Abstract: International audience; This study presents an inventory of possible chemical reactions affecting, or having affected, the Venus surface. Fluid rock reactions are simulated using experiments under conditions close to the present surface. Slabs or powder of several natural and synthetic silicate material (crystalline fresh basalt, altered basalt, obsidian, pumice and basalt glass) were reacted at 475°C in CO 2-H 2 O-H 2 S-SO 2-CO gas mixture. Most of the runs were carried out at roughly 90 bars with a duration of one week, some experiments having longer (one month) or shorter (one day) durations. The role of H 2 O content was explored through a wide range of water pressure: from dry gas for the current Venus conditions up to 590 bars (86%H 2 O) for early Venus (or other early terrestrial planets). The gas phase was sampled before the completion of the runs for chemical analysis of major gas components (CO, H 2 S, SO 2) as well as trace elements possibly released by the rocks. The altered samples were examined by a suite of mineralogical and chemical techniques (scanning and transmission electron microscopy, X-ray diffraction and spectroscopy). In dry atmosphere, the redox potential of the gas was close to the Ni/NiO buffer (−21.3 to −27.3 log fO 2), thus close to the current Venus conditions. The sample alteration is tenuous and limited to surface oxidation of glasses and coating of olivine by iron oxides, as well as the general deposition of (Ca,Na)SO 4 at the sample surface. The oxidation of glass is reflected in the formation of magnesioferrite under the surface and is accompanied by the release of Ca, Mg and Na into the gas phase or mineralized as sulfate at the surface. In wet atmosphere, obsidian recrystallizes into a mixture of plagioclase and amphibole while basaltic glass produced non-expandable clays minerals: chlorite-type (2:1:1) at the surface and likely celadonite (2:1) below the surface. Olivine is preserved. Using obsidian (the most alterable material) as a proxy of aluminosilicates, we discuss the surface reactions operating under supercritical conditions, and we used a shrinking-core equation for modeling the long-term reactions. These parametric exploration offer new insights into processes having affected the surface of Venus and contribute to the discussion of open questions such as the fate of water or the lifetime of vitreous dust or fine grain material if present in the current or past Venusian environment. Longer duration experiments will provide more kinetic parameters that can be extrapolated to the geologic history of Venus.

Abstract: International audience; Several algorithms for finding a lower bound on the makespan for the Resource Constrained Project Scheduling Problem (RCPSP) were proposed in the literature. However, fast computable lower bounds usually do not provide the best estimations and the methods that obtain better bounds are mainly based on the cooperation between linear and constraint programming and therefore are time-consuming. In this paper, a new pseudo-polynomial algorithm is proposed to find a makespan lower bound for RCPSP with time-dependent resource capacities. Its idea is based on a consecutive evaluation of pairs of resources and their cumulated workload. Using the proposed algorithm, several bounds for the PSPLIB benchmark were improved. The results for industrial applications are also presented where the algorithm could provide good bounds even for very large problem instances.

Abstract: International audience; The paper aim is to define an original walking for a 2D biped with a trunk, two identical legs with knees and massless feet. This walking is composed of a ballistic single-support phase and a distributed in time double-support phase. The ballistic movement in single support is defined by solving a boundary value problem with initial and final biped configurations and velocity conditions. These conditions ensure that at the beginning of the single support the toe of the rear leg rises without touching the ground again and at the landing of the heel there is no impact. In the double-support phase, the orientation of the two feet and other generalized coordinates which are used to define the configuration of the biped, are chosen as Bezier functions of time. The torques and ground reaction forces resulting from this double-support phase are determined by solving for the biped the inverse dynamic problem. Statement of the problem The walking motion We design biped periodic walking, which consist of distributed in time single-and double-support phases. Ballistic single-support motion is designed. During this motion the torques in all joints are zeroes except the torque in the ankle-joint of the stance leg. The torque in the ankle-joint of the stance leg is applied in order to keep its foot in the equilibrium. During double-support motion the torques are applied in all the six joints; during this time both feet rotate: foot of the rear leg-around its toe, foot of the front leg-around its heel. To explain our statement of the problem more clearly, we show Fig. 1 with several stick-figures, which results from our numerical investigations. a) b) c) d) e)

Abstract: Background Recent advances in nanomedicine have shown the great interest of active targeting associated to nanoparticles. Single chain variable fragments (scFv) of disease-specific antibodies are very promising targeting entities because they are small, not immunogenic and able to bind their specific antigens. The present paper is devoted to biological properties in vitro and in vivo of fluorescent and pegylated iron oxide nanoparticles (SPIONs-Cy-PEG-scFv) functionalized with scFv targeting Human Epithelial growth Receptor 2 (HER2). Results Thanks to a site-selective scFv conjugation, the resultant nanoprobes demonstrated high affinity and specific binding to HER2 breast cancer cells. The cellular uptake of SPIONs-Cy-PEG-scFv was threefold higher than that for untargeted PEGylated iron oxide nanoparticles (SPIONs-Cy-PEG) and is correlated to the expression of HER2 on cells. In vivo, the decrease of MR signals in HER2+ xenograft tumor is about 30% at 24 h after the injection. Conclusions These results all indicate that SPIONs-Cy-PEG-scFv are relevant tumor-targeting magnetic resonance imaging agents, suitable for diagnosis of HER2 overexpressing breast tumor.

Abstract: Theoretical study of the bromate anion reduction under steady-state conditions is performed for rotating disk electrode. Transport of the components in solution is described within the framework of the Nernst stagnant layer model. Numerical calculations carried out recently for the same system confirmed the validity of our previous approximate analytical approaches for the weak current and thin kinetic layer regimes for small and moderate values of the principal parameters of the system: ratio of the diffusion and kinetic layer thicknesses, x dk = z d/z k, for the whole range of possible currents. At the same time, these numerical results showed a pronounced change of the calculated concentration distributions, compared to the predictions of the thin kinetic layer model, for very large values of the x dk parameter. A new theoretical analysis performed in this study provides approximate analytical expressions for the concentration distributions under conditions of very strong current exceeding the bromate diffusion-limited one. These expressions demonstrate that the passing of such currents results in a cardinal change of the kinetic layer structure, compared to that for weaker currents. The comproportionation reaction takes place mainly inside a layer near the electrode surface for moderate current densities while for strong currents a BrO3 −-free layer is formed near the surface, so that the reaction is localized within a narrow “reaction zone” displaced from the electrode surface.

Abstract: International audience; A new member of the polyporphine series-cobalt polyporphine of type I (pCoP-I)-was prepared from the starting magnesium polyporphine of type I (pMgP-I) by ion exchange, i.e. by sequential processing of the pMgP-I polymer film on the electrode surface with solutions of trifluoroacetic acid (forming metalfree polyporphine of type I, pH(2)P-I) and cobalt(II) acetate in organic solvents. The completeness of each stage of ion exchange can be judged from the change in the electrochemical and spectral characteristics of the obtained polymer films of unsubstituted porphine (?H2P-I) and cobalt porphine (pCoP-I) of type I. Oxidative transformation of this polyporphine pCoP-I was performed, which led to the formation of additional bonds between the neighboring porphine units in the polymer film (transition of polymer of type I into polymer of type II, pCoP-II). The behavior of the polymer films of cobalt polyporphine of types I and II in oxygen electroreduction was studied. The films showed catalytic activity in this process.

Abstract: International audience; In order to implement the human-centric manufacturing and sustainability concepts in industry, an important effort should be done in order to model working conditions for human operators and improve them. Several studies have been conducted for mass production assembly lines where short cycle times make the work content highly repetitive. However, the case of low-volume production with long cycle times and different impacts on human operators has been rarely considered in the literature. In this paper, we develop a model to take into account the associated ergonomic risks in assembly lines with long cycle times. An optimization method is also developed in order to schedule tasks and assign the required tasks to a set of human operators taking into account the existing ergonomic risks.

Abstract: International audience; The assembly process is extremely complex for aircraft and its management requires to address numerous optimization problems related to the assignment of tasks to workstations, staffing problem for each workstation and finally the assignment of tasks to operators at each workstation. This paper treats the latter problem dealing with the assignment of tasks to operators under ergonomic constraints. The problem of optimal tasks scheduling in aircraft assembly line is modelled as Resource-Constrained Project Scheduling Problem (RCPSP). The objective of this research is to assign tasks to operators and to find an optimal schedule of task processing under economic and ergonomic constraints.

Abstract: International audience; Process of bromate reduction from aqueous acidic medium at (hemi)spherical microelectrode under steady-state conditions has been analyzed theoretically. Since bromate anion is non-electroactive within the potential range under consideration its transformation is based on the electroreduction of bromine which is present in bulk solution in small (even trace) amounts while the bromine reduction product, bromide anion, reacts irreversibly in acidic conditions with bromate anion, with regeneration of bromine, thus forming a redox mediator cycle. Similar to our previous studies of this process at rotating disk electrode it has been shown that this process possesses autocatalytic features, which may under certain conditions leads to considerable accumulation of the redox-couple components, Br2 and Br−, near the electrode surface. As a result the rate of the bromate transformation by the catalytic cycle becomes so rapid that the rate of the whole process is controlled by the bromate transport from the bulk solution to the kinetic layer near the electrode surface, i.e. the current becomes comparable to a very high BrO3− diffusion limited one. For such an autocatalytic passage of the process the radius of the microelectrode has to exceed a critical value which depends on the solution composition. This peculiarity of the system leads to the anomalous dependence of the maximal current density of the bromate reaction on the electrode size: if the electrode radius is under its critical value the current density is very small since it is determined by the discharge of bromine species from the bulk solution, with no significant transformation of bromate. On the contrary, for larger electrodes the autocatalytic EC″ mechanism becomes efficient and the passing current density can exceed the bromate diffusion limited one, i.e. it is a very strong one. The theory also predicts a complicated dependence of the maximal current on the bulk solution concentrations of bromate and protons.

Abstract: As the adverse impacts of hydrological extremes increase in many regions of the world, a better understanding of the drivers of changes in risk and impacts is essential for effective flood and drought risk management and climate adaptation. However, there is currently a lack of comprehensive, empirical data about the processes, interactions and feedbacks in complex human-water systems leading to flood and drought impacts. Here we present a benchmark dataset containing socio-hydrological data of paired events, i.e., two floods or two droughts that occurred in the same area. The 45 paired events occurred in 42 different study areas and cover a wide range of socio-economic and hydro-climatic conditions. The dataset is unique in covering both floods and droughts, in the number of cases assessed, and in the quantity of socio-hydrological data. The benchmark dataset comprises: 1) detailed review style reports about the events and key processes between the two events of a pair; 2) the key data table containing variables that assess the indicators which characterise management shortcomings, hazard, exposure, vulnerability and impacts of all events; 3) a table of the indicators-of-change that indicate the differences between the first and second event of a pair. The advantages of the dataset are that it enables comparative analyses across all the paired events based on the indicators-of-change and allows for detailed context- and location-specific assessments based on the extensive data and reports of the individual study areas. The dataset can be used by the scientific community for exploratory data analyses e.g. focused on causal links between risk management, changes in hazard, exposure and vulnerability and flood or drought impacts. The data can also be used for the development, calibration and validation of socio-hydrological models. The dataset is available to the public through the GFZ Data Services (Kreibich et al. 2023, link for review: https://dataservices.gfz-potsdam.de/panmetaworks/review/923c14519deb04f83815ce108b48dd2581d57b90ce069bec9c948361028b8c85/).

Abstract: International audience; The process of electroreduction of bromate anion BrO3- from aqueous solutions on catalytically inactive (e.g., carbon) electrodes is theoretically described in the framework of the generalized Nernst layer model in which the Nernst-layer thickness is chosen independently for each system’s component according to the Levich formula. For this system, the numerical algorithm is developed for solving the system diffusion- kinetic equations for the case of excessive content of protons in solution and one-dimensional transport (corresponding to RDE) under stationary conditions. The results are compared with conclusions of the approximate analytical theory proposed for the same system in our recent study (J. Electroanal. Chem., 2016, vol. 779, p. 146). The closeness of the numerical and analytical data makes it possible to conclude that both approaches can be used for solving this problem. Deviations are observed only when the approximations lying in the basis of the corresponding analytical relationships are violated.

Abstract: International audience; Theory of the steady-state electroreduction of bromate-anion at rotating disk electrode has been developed. Bulk solution contains high concentrations of bromate anion and a strong acid (which are non-electroactive at the electrode) as well as a tracer amount of bromine. The current passes owing to bromine which is reduced to bromide ion that participates further in the comproportionation reaction with bromate anion, with regeneration of bromine. This process has been described for the first time on the basis of convective diffusion transport equations for solute components, bromate and bromide ions as well as bromine, with taking into account the difference of their diffusion coefficients. Approximate analytical solutions for all concentration distributions have been derived. It has been demonstrated that the passage of the bromate process depends crucially on the value of the ratio of two characteristic lengths: individual diffusion-layer thicknesses determined for each transporting component by an interplay of the diffusion and convection mechanisms, and kinetic layer thickness where the comproportionation reaction takes place. For small values of their ratio, bromide ions cross the diffusion layer and react with bromate ions only in the bulk solution so that this process does not affect the electrode reaction and the current is very weak since it is related to reduction of bromine from the bulk solution. For moderate values of this parameter (if the ratio of these thicknesses is less than 6), a thin kinetic layer is formed deeply inside the diffusion layer where the comproportionation reaction is localized while bromide ions are absent in the outer part of the diffusion layer where bromate ions are transported from the bulk solution towards the kinetic layer and bromine is transferred in the opposite direction. Under such conditions, this bromine flux to the bulk solution makes insufficiently efficient the redox cycle formed by the electrode and comproportionation reactions, and the passing current remains relative weak. Finally, for large values of the key parameters (if the ratio of these layer thicknesses exceeds its critical value equal to 6), the redox cycle demonstrates its autocatalytic features, i.e. the reduction of bromate ions may lead to accumulation of enormous amounts of the redox couple components, bromine and bromide ion, near the electrode surface, thus resulting in a very strong current, comparable with (or even exceeding) the formally defined “diffusion-limited current for bromate anion”. Expressions for the concentration distributions inside the (thin) kinetic layer, as well as those for the maximal current density, derived within the framework of the convective-diffusion theory are in agreement with those found for the Generalized Nernst Layer model proposed by us earlier. On the contrary, there is a marked deviation of these results from those for the conventional Nernst layer model, i.e. this simplified approach is not applicable for quantitative description of the process, even though it provides its correct qualitative picture. For the outer part of the diffusional layer the newly derived concentration distributions are essentially different from predictions of both previous approaches.

Abstract: International audience; Ion solvation process has been analysed for the spherically symmetrical system where an ion is located inside a cavity surrounded by an isotropic nonlocal dielectric medium. It has been proven that for any dielectric properties of the medium, the electric field outside the cavity as well as the ion solvation energy depend only on the total ion charge but not of the particular distribution of the ion charge density inside the cavity. These characteristics remain unchanged if the charge is displaced from the external boundary of the cavity into it. Analytical formulas for them have been derived for a particular model of the nonlocal dielectric function. Comparison of results for the solvation energy on the basis of this new theory and of the conventional approach (disregarding the existence of the cavity) shows a significant difference between their predictions if the ion charge is displaced inside the ion cavity.

Abstract: International audience; In the presence of carbon nanotubes (CNTs), palladium (Pd)-polypyrrole (PPy)@CNT nanocomposites have been synthesized by way of one-pot and one-step colloidal synthesis from a solution of a palladium inorganic salt and organic pyrrole as monomeric precursor to PPy. This efficient method leads to the growth of nanoparticles of the palladium inorganic component distributed inside a polymer matrix supported on CNTs. After characterization, palladium-PPy@CNT nanocomposites have been employed as efficient heterogeneous catalysts for direct C-H bond functionalization toward C-C bond coupling formation. The notable catalytic activity of the palladium-PPy@CNT nanocomposite decreased with successive catalytic cycles when using the same portion of the composite. This was attributed to palladium redistribution inside the PPy matrix, which occurs by way of a specific mechanism involving the reaction solvent and the composite during C-C coupling reaction. This mechanism is recrystallization of palladium nanoparticles in conductive PPy matrix. Nevertheless, the use of palladium-PPy@CNT nanocomposite in first cycle of investigated catalytic reaction facilitates C-C bond coupling formation: reaction occurs at lower temperature in comparison with homogeneous catalysts.

Abstract: International audience; The growing concern about air quality and the impact exhaust particles can have on the environment has resulted in the increased use of alternative fuels. A sampling campaign from a conventional heavy diesel engine operated in typical transient cycle or steady-state condition, and running on diesel, 30% biodiesel in diesel, and 100% biodiesel was carried out. The particulate composition was characterized using Fourier Transform Infrared (FTIR) spectroscopy, Two-step Laser Mass Spectrometry (L2MS), Secondary Ion Mass Spectrometry (SIMS), thermo-optical analysis, and capillary electrophoresis. Elemental carbon is demonstrated to decrease from diesel to 100% biodiesel, in agreement with the evolution of aromatic bands and the MS abundance of Cn– fragments, while organic carbon exhibits a constant level irrespective of the working regime. Aliphatic, aromatic, carboxyl, carbonyl, hydroxyl functionalities, and nitro compounds are found to depend on the engine-working regime. Mass spectra are mainly characterized by alkyl fragments (CnH2n+1+), associated to normal and branched alkanes, PAHs and their alkylated derivatives. The addition of biodiesel to diesel changes the particulate composition towards more oxygenated constituents, such as carbonyl groups attributed to methyl ester CH3O+ fragments of unburned biodiesel. Fuel-specific fragments have been identified, such as C3H7O+ for diesel, and C2H3O2+ and CH3O– for biodiesel. Nitrogenized compounds are revealed by -NO2 functionalities and N-containing fragments. Principal Component Analysis (PCA) was successfully applied to discriminate the engine operating conditions, with a higher variance given by the fuel, thus allowing to better evaluate the environmental impacts of alternative energy source emissions.

Abstract: Schizophrenia (SCZ) is a complex mental disorder that may result in some combination of hallucinations, delusions and disorganized thinking. Here SCZ patients and healthy controls (CTLs) report their level of confidence on a forced-choice task that manipulated the strength of sensory evidence and prior information. Neither group's responses can be explained by simple Bayesian inference. Rather, individual responses are best captured by a model with different degrees of circular inference. Circular inference refers to a corruption of sensory data by prior information and vice versa, leading us to ‘see what we expect' (through descending loops), to ‘expect what we see' (through ascending loops) or both. Ascending loops are stronger for SCZ than CTLs and correlate with the severity of positive symptoms. Descending loops correlate with the severity of negative symptoms. Both loops correlate with disorganized symptoms. The findings suggest that circular inference might mediate the clinical manifestations of SCZ., Schizophrenia is a mental disorder characterized by hallucinations and delusions. Here the authors report a novel probabilistic inference task in which compared to healthy subjects, schizophrenia patients show greater degree of circular inference that matches the severity of their clinical symptoms.

Abstract: International audience; Three alternative methods were developed for the synthesis of modifying palladium-polypyrrole layers on the surface of an inert electrode. Their electrocatalytic activity toward formaldehyde under inert atmosphere was checked. All the suggested methods are one-stage and allow synthesis of a film on the electrode surface from a solution containing a palladium salt and pyrrole in the absence of other active reagents. The electrochemical methods (potentiodynamic and double cathodic and anodic pulses techniques) in an aqueous medium give films with poorly reproducible electrocatalytic properties, while the chemical redox synthesis affords films with reproducibly high electroactivity toward methylene glycolate.

Abstract: International audience; Theoretical analysis has been developed for the reduction reaction of the non-electroactive bromate anion from its aqueous solution at a thin-layer porous electrode on the surface of a membrane transporting protons from anode under steady-state 1D conditions. The cathodic process is realized via a cycle composed of the reversible Br2 to 2 Br− transformation and of the irreversible (owing to high acidity of the solution) comproportionation reaction between bromate and bromide which regenerates bromine. Protons (assumed to be in great excess) are transported to the comproportionation-reaction (kinetic) layer near the electrode both via the membrane and from the bulk solution. As it has been demonstrated by calculations for the dependence of the local value of the maximal current density, jmax, on the local value of the diffusion layer thickness, zd, high values of the current density cannot be achieved for relatively thin diffusion layers. Contrary to intuitive expectations, for sufficiently thick diffusion layers the current density may reach extremely high values comparable with the diffusion-limited flux of bromate anions (if they could react at the electrode), even for a tracer amount of Br2 in the bulk solution. Such strong steady-state currents originate from the autocatalytic character of this redox-mediating cycle (EC″ mechanism) resulting in progressive accumulation of the components of the Br2/Br− mediating redox couple near the electrode surface. Relations between the fluxes of bromate and bromide anions, protons and bromine across the diffusion layer in solution as well as the flux of protons across the membrane have been established. Approximate analytical expressions for all characteristics of the system (concentration profiles, maximal current, etc.) have been derived for two regimes corresponding either to “weak currents” or to “thin kinetic layer”. The quantitative criterion for protons to be considered as being in great excess compared to bromate anions has been derived for both an ion-impermeable electrode/bromate solution cell (corresponding to the rotating-disk electrode system, RDE) and a proton-exchange membrane/porous electrode/bromate solution configuration.

Abstract: International audience; The process of electroxidative polymerization of magnesium 5,15-di(N-methoxyphenyl)porphine MgP(MeOPh)(2) is studied. The presence of substituents in positions 5 and 15 of the porphine macroring makes reactive two of its four meso positions, which allows new bonds to be formed only in the opposite positions 10 and 20. As a result, the process of electropolymerization of this substituted monomer at its oxidation can produce only linear chains, in contrast to unsubstituted magnesium porphine MgP for which the polymer structure can both be linear and contain zigzag and/or cruciform fragments.

Abstract: International audience; A method for modification of the inert electrode surface with an electroactive polymeric film containing the CoN4 catalytic site has been suggested and approved. The described approach affords the maximal content of the metal porphine moiety per unit weight of the coating. The classical method of introduction of an ion into the porphine macrocycle has been replaced by electrochemical polarization of an electrode with a metallated film in a dilute solution. The metalation efficiency has been demonstrated by the presence of changes in the current-voltage and spectral characteristics of the resulting polymeric films of the unsubstituted porphine pH(2)P and cobalt polyporphine pCoP.

Abstract: The reduction of nonelectroactive bromate anion BrO 3 - from acidic solutions while limiting the maximum current by diffusion transport of protons was studied by methods of numerical integration of transport equations. The calculation was performed based on a generalization of the Nernst steady diffusion layer model, in which the choice of the layer thickness for each component of the system is made using the Levich formula and takes into account the difference in diffusivity between the components. This difference in layer thickness was shown to have a significant effect on the main characteristics of the system, such as the maximum possible discharge current, and also the concentration profiles of the components.

Abstract: The behavioural rhythms of organisms are thought to be under strong selection, influenced by the rhythmicity of the environment1,2,3,4. Such behavioural rhythms are well studied in isolated individuals under laboratory conditions1,5, but free-living individuals have to temporally synchronize their activities with those of others, including potential mates, competitors, prey and predators6,7,8,9,10. Individuals can temporally segregate their daily activities (for example, prey avoiding predators, subordinates avoiding dominants) or synchronize their activities (for example, group foraging, communal defence, pairs reproducing or caring for offspring)6,7,8,9,11. The behavioural rhythms that emerge from such social synchronization and the underlying evolutionary and ecological drivers that shape them remain poorly understood5,6,7,9. Here we investigate these rhythms in the context of biparental care, a particularly sensitive phase of social synchronization12 where pair members potentially compromise their individual rhythms. Using data from 729 nests of 91 populations of 32 biparentally incubating shorebird species, where parents synchronize to achieve continuous coverage of developing eggs, we report remarkable within- and between-species diversity in incubation rhythms. Between species, the median length of one parent’s incubation bout varied from 1–19 h, whereas period length—the time in which a parent’s probability to incubate cycles once between its highest and lowest value—varied from 6–43 h. The length of incubation bouts was unrelated to variables reflecting energetic demands, but species relying on crypsis (the ability to avoid detection by other animals) had longer incubation bouts than those that are readily visible or who actively protect their nest against predators. Rhythms entrainable to the 24-h light–dark cycle were less prevalent at high latitudes and absent in 18 species. Our results indicate that even under similar environmental conditions and despite 24-h environmental cues, social synchronization can generate far more diverse behavioural rhythms than expected from studies of individuals in captivity5,6,7,9. The risk of predation, not the risk of starvation, may be a key factor underlying the diversity in these rhythms., The study was supported by the Max Planck Society (to B.K.).

Abstract: The study is devoted to analyzing the electroreduction of bromate anion BrO 3 - on catalytically inactive (e.g., carbon) electrodes by numerical methods. This process is realized due to the combination of the reversible mediator pair Br2/Br- and the process of comproportionation (reaction of bromate and bromide anions) in solution phase. These reactions increase the concentration of bromine and bromide near the electrode surface; hence, this process is autocatalytic (EC″ mechanism). Within the framework of this study, a numerical algorithm which allows the system of diffusion-kinetic equations to be solved for this system is proposed for one-dimensional transport and the process under steady-state conditions. The results are compared with the conclusions of the approximate analytical theory published in Electrochim. Acta, 2015, vol. 173, p. 779, which allows inferring that both approaches are correct. The deviation between the latter is observed only in the cases of violation of approximations lying in the basis of the corresponding analytical relationships. Thus, the predictions of the analytical theory of practical interest can be considered as reliably confirmed by numerical calculations, particularly, the prediction on the nonmonotonous dependence of the maximum current on the diffusion layer thickness (or the RDE rotation rate) including the anomalous region of this dependence in which the current increases with the increase in the diffusion layer thickness.

Abstract: International audience; Novel synthetic route towards electroactive films of Co(II) polyporphine has been elaborated. It is based on the electrochemical transformation of the metal-free polyporphine film with replacement of protons inside the macrocycles by Co(II) cations. Compared to the conventional procedure of such ion exchange based on extended thermal treatment of macrocycles in the presence of the saturated solution of the metal salt, the developed approach allows one to use dilute solutions of the metal cation at ambient conditions. The resulting Co(II) polyporphine possesses a very high concentration of CoN4 functional groups which are known as prospective catalysts of various processes.

Abstract: Process of the bromate anion reduction in the presence of a very low bromine concentration from an acidic solution for the one-dimensional transport under steady-state conditions has been analyzed theoretically. Bromate being non-electroactive in the potential range under consideration, its transformation takes place via the redox cycle composed by the reversible couple, Br 2 /Br − , and the irreversible comproportionation reaction inside the solution phase between BrO 3 − , Br − and protons which regenerates Br 2 . Specific feature of this process compared to the conventional EC' mechanism is the progressive increase in the overall amount of the components of the redox couple owing to consumed bromate. As a result, this novel EC” mechanism possesses autocatalytic properties so that even a trace amount of bromine in the bulk solution may result in very high current densities, up to the those limited by the diffusion of the principal solution components, bromate and protons. Unlike our previous study of this system carried out for excess of protons compared to bromate [Electrochim. Acta, 173 (2015) 779-795] we consider the opposite situation where bromate is in great excess compared to protons so that the transport of the latter component from the bulk solution limits the maximal current. Approximate analytical formulas have been derived for all characteristics of the system based on the condition of either a relatively weak current or a thin kinetic layer compared to the diffusion one. Behavior of the system depends crucially on the relation between the diffusion layer thickness, z d , and the kinetic layer thickness, z k (determined by the rate of the homogeneous reaction). For a very thin diffusion layers: z d z k , bromide anions leave the diffusion layer and react with bromate anions only in the bulk solution. Then, both the polarization curve and the maximal current correspond to the electrode reaction of Br 2 molecules from the bulk solution, without a significant effect due to BrO 3 − presence. In the intermediate range of the diffusion layer thicknesses, z k z d z k , bromide anions generated at the electrode are consumed by the comproportionation reaction within a thin kinetic layer (located deeply inside the diffusion layer) while bromine molecules produced by this reaction diffuse partially to the electrode, generating again bromide anions. This combination of the chemical and electrochemical steps results in an autocatalytic cycle, based on the Br − /Br 2 mediating redox couple, which consumes a significant amount of bromate anions. The maximal current becomes much higher, exceeding the one limited by the bromine diffusion from the bulk solution, and it depends essentially on the kinetic layer thickness. In the third range of even larger diffusion layer thicknesses, 6 z k z d , the amounts of the accumulated redox-couple components become so high that the current is limited by the diffusion of protons from the bulk solution into the kinetic layer. This diffusion limited current is proportional to the bulk-solution proton concentration and it may reach very high values. The theory predicts a complicated behavior of the maximal current as a function of the diffusion layer thickness (or of the disk rotation rate for the RDE technique), with a maximum and a minimum separated by the range with an anomalous variation: increase of the maximal current with increase of the diffusion layer thickness (“autocatalytic interval”).

Abstract: International audience; Theoretical analysis has been developed for the reduction process of the non-electroactive bromate anion via a redox-mediating cycle composed of the reversible Br-2-to-Br- transformation at the electrode and of the irreversible (owing to high acidity of the solution) comproportionation reaction between Br- and BrO3- which regenerates Br-2. Owing to the autocatalytic character of this cycle (EC '' mechanism) even a tracer amount of Br-2 in the bulk solution may result in enormous values of the reduction current compared to the BrO3- diffusion-limited one towards the electrode surface where it is consumed inside a thin kinetic layer by the comproportionation reaction. Unlike the preceding theoretical papers on this process (Electrochim. Acta, 2015, 173, 779; Doklady Phys. Chem., 2016,468,37; Russ. J. Electrochem., 2016, 52, in press), this study is based on a more advanced theoretical concept of the Generalized Nernst-Layer Model which takes into account that the difference in the diffusion coefficients of BrO3-, Br- and Br-2 means the non-equality of the diffusion layer thicknesses for these species, as evidenced by the Levich formula for the RDE. Approximate analytical expressions for all characteristics of the system have been derived for two regimes corresponding either to "weak currents" or to "thin kinetic layer". In particular, the maximal current for the diffusion-limited conditions has turned out to depend on the novel parameter of the model, i.e. on the ratio of the diffusion layer thicknesses for BrO3- and Br-2, which in its turn is expressed via the ratio of their diffusion coefficients.

Abstract: International audience; The present volume is the fifth in the series of yearbooks with the title Globalistics and Globalization Studies. The subtitle of the present volume is Global Transformations and Global Future. We become more and more accustomed to think globally and to see global processes. And our future can all means be global. However, is this statement justified? Indeed, in recent years, many have begun to claim that globalization has stalled, that we are rather dealing with the process of anti-globalization. Will not we find ourselves at some point again in an edifice spanning across the globe, but divided into national apartments, separated by walls of high tariffs and mutual suspicion? Of course, some setbacks are always possible, because the process of globalization cannot develop smoothly. It is a process which is itself emerging from contradictions and is shaped by a new contradiction. They often go much further than underlying systemic changes allow. They break forward, as the vanguard of a victorious army, and then often meet resistance of various social and political forces and may suddenly start to roll back just at the moment when everyone expects their further offensive. We believe that this is what is happening with globalization at present. The yearbook will be interesting to a wide range of researchers, teachers, students and all those who are concerned about global issues.

Abstract: International audience; Globalization processes continue to develop and we should pay more and more attention to them. We also need to systematize our ideas about globalization and Global Studies to somehow fit the realities. We hope that our Yearbook contributes to the realization of this goal. The present volume is the fifth in the series of yearbooks with the title Globalistics and Globalization Studies1. However, why Globalistics, not Global Studies? Elsewhere we explained that the notion of Globalistics first appeared in Russia, this is a translation of the Russian term globalistika; however, we believe it might be useful within the English Global Studies thesaurus. We are sure that the introduction of this term is meaningful, because it expresses the vision of systemic and epistemological unity of global processes, the presence of a relatively autonomous field with its own research subject. Morphologically this term is identical with such well-established designations of academic disciplines as Economics, Linguistics, Physics, and so on (for more details see Grinin, Ilyin, and Korotayev 2012b, 2013b, 2014b).

Abstract: International audience; This paper presents an easy, efficient and reproducible way to obtain cobalt polyporphine films. A fast three step process (less than one hour) based on electrosynthesis of magnesium polyporphine of type I followed by a demetallation in acid medium and then cobalt insertion inside the porphine units allowed us to obtain an interesting material with a high density of active cobalt(II) centers. Kinetics studies were conducted to determine the best conditions for the demetallation and remetallation steps. Moreover, IRATR and UV-visible measurements attested that the initial molecular structure of the porphine units was kept during the three step process. Qualitative composition of polyporphine films has been confirmed via XPS and EDX methods. In situ specific conductivity of these polyporphine polymers of type I has been determined as a function of the imposed potential, i.e. of the oxidation degree. (C) 2016 Elsevier Ltd.

Abstract: International audience; The process of electroreduction of bromate anion BrO3 in acidic solutions at catalytically inactive electrodes when bromate anions are in excess compared to protons has been studied by numerical integration of transport equations. Under these conditions, the maximum possible current is limited by the limiting diffusion current of protons (rather than bromate), since both ions are consumed in the comproportionation reaction. It has been demonstrated that the curve of maximum current versus diffusion layer thickness has an anomalous segment where the current increases with an increase of the latter.

Abstract: In the present paper, we combine numerical and experimental approaches to study the dynamics of stable and unstable internal wave attractors. The problem is considered in a classic trapezoidal set-up filled with a uniformly stratified fluid. Energy is injected into the system at global scale by the small-amplitude motion of a vertical wall. Wave motion in the test tank is measured with the help of conventional synthetic schlieren and particle image velocimetry techniques. The numerical set-up closely reproduces the experimental one in terms of geometry and the operational range of the Reynolds and Schmidt numbers. The spectral element method is used as a numerical tool to simulate the nonlinear dynamics of a viscous salt-stratified fluid. We show that the results of 3D calculations are in excellent qualitative and quantitative agreement with the experimental data, including the spatial and temporal parameters of the secondary waves produced by triadic resonance instability. Further, we explore experimentally and numerically the effect of lateral walls on secondary currents and spanwise distribution of velocity amplitudes in the wave beams. Finally, we test the assumption of a bidimensional flow and estimate the error made in synthetic schlieren measurements due to this assumption.

Abstract: International audience; Palladium-polypyrrole nanocomposite materials with high electrocatalytic activity toward formaldehyde in an alkaline solution (methylene glycolate) have been synthesized via a one-step redox route. Key factors that have an effect on the sensor properties of palladium nanoparticles have been determined. It has been demonstrated for the first time that the emergence of not only the forward but also the reverse wave of formaldehyde oxidation on palladium particles is associated with the oxidation of methylene glycolate rather than intermediate species.

Abstract: International audience; Composite materials of Prussian blue-polypyrrole (PB/PPy) on the surface of indium tin oxide (ITO)-coated glasses were obtained via one-step chemical (redox) and one-stage electrochemical procedures in mixed solution of iron (III), hexacyanoferrate (III), and pyrrole with various concentration ratios of components in nitrate supporting electrolyte. Electrochemical stability of composite films depends on the amount of Py in synthetic solution, whereas color contrast coefficient values depend on the type of synthetic procedure. PB/PPy film electrochromic response (tested by spectroelectrochemical potentiodynamic measurements) was compared with response of both pure PB and pure PPy films. It was shown that degradation of composite films occurs due to PB component instability in Prussian white form. The highest value of color contrast coefficient and great electrochemical stability were revealed for composite films obtained via redox-synthesis procedure from solution with 0.1 mM [Fe3+ + Fe(CN)(6) (3-)] and 1.0 mM D N integral (PB/PPy-Ch-1:1:10 system).

Abstract: Tau protein has been extensively studied due to its key roles in microtubular cytoskeleton regulation and in the formation of aggregates found in some neurodegenerative diseases. Recently it has been shown that zinc is able to induce tau aggregation by interacting with several binding sites. However, the precise location of these sites and the molecular mechanism of zinc-induced aggregation remain unknown. Here we used Nuclear Magnetic Resonance (NMR) to identify zinc binding sites on hTau40 isoform. These experiments revealed three distinct zinc binding sites on tau, located in the N-terminal part (H14, H32, H94, and H121), the repeat region (H299, C322, H329 and H330) and the C-terminal part (H362, H374, H388 and H407). Further analysis enabled us to show that the C-terminal and the N-terminal sites are independent of each other. Using molecular simulations, we modeled the structure of each site in a complex with zinc. Given the clinical importance of zinc in tau aggregation, our findings pave the way for designing potential therapies for tauopathies.HighlightsZinc is known to induce tau aggregation in neurodegenerative diseasesZinc binding locations and mechanism are not yet clearUsing NMR we localized 3 zinc binding site on tauBy molecular simulations, we proposed a modeled structure of each siteOur findings pave the way for designing potential therapies for tauopathies

Abstract: International audience; Primary open-angle glaucoma (POAG) is a frequent blindness-causing neurodegenerative disorder characterized by optic nerve and retinal ganglion cell damage most commonly due to a chronic increase in intraocular pressure. The preservation of visual function in patients critically depends on the timeliness of detection and treatment of the disease, which is challenging due to its asymptomatic course at early stages and lack of objective diagnostic approaches. Recent studies revealed that the pathophysiology of glaucoma includes complex metabolomic and proteomic alterations in the eye liquids, including tear fluid (TF). Although TF can be collected by a noninvasive procedure and may serve as a source of the appropriate biomarkers, its multi-omics analysis is technically sophisticated and unsuitable for clinical practice. In this study, we tested a novel concept of glaucoma diagnostics based on the rapid high-performance analysis of the TF proteome by differential scanning fluorimetry (nanoDSF). An examination of the thermal denaturation of TF proteins in a cohort of 311 ophthalmic patients revealed typical profiles, with two peaks exhibiting characteristic shifts in POAG. Clustering of the profiles according to peaks maxima allowed us to identify glaucoma in 70% of cases, while the employment of artificial intelligence (machine learning) algorithms reduced the amount of false-positive diagnoses to 13.5%. The POAG-associated alterations in the core TF proteins included an increase in the concentration of serum albumin, accompanied by a decrease in lysozyme C, lipocalin-1, and lactotransferrin contents. Unexpectedly, these changes were not the only factor affecting the observed denaturation profile shifts, which considerably depended on the presence of low-molecular-weight ligands of tear proteins, such as fatty acids and iron. Overall, we recognized the TF denaturation profile as a novel biomarker of glaucoma, which integrates proteomic, lipidomic, and metallomic alterations in tears, and monitoring of which could be adapted for rapid non-invasive screening of the disease in a clinical setting.

Abstract: Dark matter elastic scattering off nuclei can result in the excitation and ionization of the recoiling atom through the so-called Migdal effect. The energy deposition from the ionization electron adds to the energy deposited by the recoiling nuclear system and allows for the detection of interactions of sub-GeV/c2 mass dark matter. We present new constraints for sub-GeV/c2 dark matter using the dual-phase liquid argon time projection chamber of the DarkSide-50 experiment with an exposure of (12 306±184) kg d. The analysis is based on the ionization signal alone and significantly enhances the sensitivity of DarkSide-50, enabling sensitivity to dark matter with masses down to 40 MeV/c2. Furthermore, it sets the most stringent upper limit on the spin independent dark matter nucleon cross section for masses below 3.6 GeV/c2.

Abstract: We define a measure of "complexity" of a braid which is natural with respect to both an algebraic and a geometric point of view. Algebraically, we modify the standard notion of the length of a braid by introducing generators $\Delta\_{ij}$, which are Garside-like half-twists involving strings $i$ through $j$, and by counting powered generators $\Delta\_{ij}^k$ as $\log(|k|+1)$ instead of simply $|k|$. The geometrical complexity is some natural measure of the amount of distortion of the $n$ times punctured disk caused by a homeomorphism. Our main result is that the two notions of complexity are comparable. This gives rise to a new combinatorial model for the Teichmueller space of an $n+1$ times punctured sphere. We also show how to recover a braid from its curve diagram in polynomial time. The key r\^ole in the proofs is played by a technique introduced by Agol, Hass, and Thurston., Comment: Version 2: added section on Teichmueller geometry, removed section on train tracks

Abstract: We study tunneling of charge carriers in single- and bilayer graphene. We propose an explanation for non-zero "magic angles" with 100% transmission for the case of symmetric potential barrier, as well as for their almost-survival for slightly asymmetric barrier in the bilayer graphene known previously from numerical simulations. Most importantly, we demonstrate that these magic angles are not protected in the case of bilayer and give an explicit example of a barrier with very small electron transmission probability for any angles. This means that one can lock charge carriers by a p-n-p (or n-p-n) junction without opening energy gap. This creates new opportunities for the construction of graphene transistors., Comment: 13 pages, 10 figures

Abstract: Context. In 2009, the Sun and the Earth passed through the equatorial plane of Jupiter and therefore the orbital planes of its main satellites. It was the equinox on Jupiter. This occurrence made mutual occultations and eclipses between the satellites possible. Experience has shown that the observations of such events provide accurate astrometric data able to bring new information on the dynamics of the Galilean satellites. Observations are made under the form of photometric measurements, but need to be made through the organization of a worldwide observation campaign maximizing the number and the quality of the data obtained. Aims. This work focuses on processing the complete database of photometric observations of the mutual occultations and eclipses of the Galilean satellites of Jupiter made during the international campaign in 2009. The final goal is to derive new accurate astrometric data. Methods. We used an accurate photometric model of mutual events adequate with the accuracy of the observation. Our original method was applied to derive astrometric data from photometric observations of mutual occultations and eclipses of the Galilean satellites of Jupiter. Results. We processed the 457 lightcurves obtained during the international campaign of photometric observations of the Galilean satellites of Jupiter in 2009. Compared with the theory, for successful observations, the r.m.s. of O-C residuals are equal to 45.8 mas and 81.1 mas in right ascension and declination, respectively; the mean O-C residuals are equal to -2 mas and -9 mas in right ascension and declination, respectively, for mutual occultations; and -6 mas and +1 mas in right ascension and declination, respectively, for mutual eclipses. © ESO, 2014.

In 2009, the Sun and the Earth passed through the equatorial plane of Jupiter and therefore the orbital planes of its main satellites. It was the equinox on Jupiter. This occurrence made mutual occultations and eclipses between the satellites possible. Experience has shown that the observations of such events provide accurate astrometric data able to bring new information on the dynamics of the Galilean satellites. Observations are made under the form of photometric measurements, but need to be made through the organization of a worldwide observation campaign maximizing the number and the quality of the data obtained. Aims. This work focuses on processing the complete database of photometric observations of the mutual occultations and eclipses of the Galilean satellites of Jupiter made during the international campaign in 2009. The final goal is to derive new accurate astrometric data. Methods. We used an accurate photometric model of mutual events adequate with the accuracy of the observation. Our original method was applied to derive astrometric data from photometric observations of mutual occultations and eclipses of the Galilean satellites of Jupiter. Results. We processed the 457 lightcurves obtained during the international campaign of photometric observations of the Galilean satellites of Jupiter in 2009. Compared with the theory, for successful observations, the r.m.s. of O–C residuals are equal to 45.8 mas and 81.1 mas in right ascension and declination, respectively; the mean O–C residuals are equal to –2 mas and –9 mas in right ascension and declination, respectively, for mutual occultations; and –6 mas and +1 mas in right ascension and declination, respectively, for mutual eclipses. astronomical databases: miscellaneous planets and satellites: general occultations eclipses ephemerides idline A&A 572, A120 (2014) cover_date December 2014 first_month 12 last_month 12 first_year 2014 last_year 2014 This work was supported by the Russian Foundation for Basic Research (project no. 12-02-00294), by The European contract ESPaCE (FP7-grant agreement 263466), by the Scientific Council of Paris Observatory, by the CNRS PICS 3840 France-Russia, by the Programme National de Planétologie (CNES and CNRS) and by the National Science Foundation of China (Grant No 11273014) and the Fundamental Research Funds for the Central Universities.

Abstract: International audience; Eclogitisation is a major metamorphic process of continental subduction zones, where transformation of dry lower crustal rocks into eclogites seem to correlate with seismogenic events. Eclogitisation can occur at high pressure during hydration of granulite, but the physical processes controlling the hydration of dry, impermeable granulite remain poorly understood. Here, we present a new fully coupled hydro-chemical model of a non-deforming porous rock which undergoes metamorphic reactions in response to fluid pressure variations. Conservation equations for total and solid mass are solved, and fluid and solid densities are calculated with look-up tables computed from models relying on equilibrium thermodynamics. Our model shows that a fluid pressure pulse generates a pressure gradient that causes densification when the pressure required for eclogitisation is reached. The reaction generates porosity and subsequent porous fluid flow into the initially non-porous impermeable granulite. This process lasts as long as the pressure pulse is maintained, but high pressure within eclogite can persist for a longer time. The hydration front propagates tens of centimetres into the granulite in the order of weeks to months. We show that propagation of a hydration-reaction front is effectively a diffusive process, with diffusivity in the order of 10 −9 m 2 •s −1 for eclogitisation as in Holsnøy, Norway. Reactive hydration of impermeable granulite is possible because its solid density is smaller than that of eclogite. We discuss the application of our model for eclogitisation and also for other reactions for which hydration of impermeable rock is possible.

Abstract: We present a novel approach for the search of dark matter in the DarkSide-50 experiment, relying on Bayesian Networks. This method incorporates the detector response model into the likelihood function, explicitly maintaining the connection with the quantity of interest. No assumptions about the linearity of the problem or the shape of the probability distribution functions are required, and there is no need to morph signal and background spectra as a function of nuisance parameters. By expressing the problem in terms of Bayesian Networks, we have developed an inference algorithm based on a Markov Chain Monte Carlo to calculate the posterior probability. A clever description of the detector response model in terms of parametric matrices allows us to study the impact of systematic variations of any parameter on the final results. Our approach not only provides the desired information on the parameter of interest, but also potential constraints on the response model. Our results are consistent with recent published analyses and further refine the parameters of the detector response model., Comment: 24 pages, 12 figures, 1 table

Abstract: We present re-processed flux calibrated spectra of 406 stars from the UVES-POP stellar library in the wavelength range 320-1025 nm, which can be used for stellar population synthesis. The spectra are provided in the two versions having spectral resolving power R=20,000 and R=80,000. Raw spectra from the ESO data archive were re-reduced using the latest version of the UVES data reduction pipeline with some additional algorithms that we developed. The most significant improvements in comparison with the original UVES-POP release are: (i) an updated Echelle order merging, which eliminates "ripples" present in the published spectra, (ii) a full telluric correction, (iii) merging of non-overlapping UVES spectral setups taking into account the global continuum shape, (iv) a spectrophotometric correction and absolute flux calibration, and (v) estimates of the interstellar extinction. For 364 stars from our sample, we computed atmospheric parameters $T_\mathrm{eff}$, surface gravity log $g$, metallicity [Fe/H], and $\alpha$-element enhancement [$\alpha$/Fe] by using a full spectrum fitting technique based on a grid of synthetic stellar atmospheres and a novel minimization algorithm. We also provide projected rotational velocity $v\sin i$ and radial velocity $v_{rad}$ estimates. The overall absolute flux uncertainty in the re-processed dataset is better than 2% with sub-% accuracy for about half of the stars. A comparison of the recalibrated UVES-POP spectra with other spectral libraries shows a very good agreement in flux; at the same time, $Gaia$ DR3 BP/RP spectra are often discrepant with our data, which we attribute to spectrophotometric calibration issues in $Gaia$ DR3., Comment: 26 pages, 19 figures, accepted for publication in ApJS

Abstract: We report on the search for dark matter WIMPs in the mass range below 10 GeV/c$^2$, from the analysis of the entire dataset acquired with a low-radioactivity argon target by the DarkSide-50 experiment at LNGS. The new analysis benefits from more accurate calibration of the detector response, improved background model, and better determination of systematic uncertainties, allowing us to accurately model the background rate and spectra down to 0.06 keV$_{er}$. A 90% C.L. exclusion limit for the spin-independent cross section of 3 GeV/c$^2$ mass WIMP on nucleons is set at 6$\times$10$^{-43}$ cm$^2$, about a factor 10 better than the previous DarkSide-50 limit. This analysis extends the exclusion region for spin-independent dark matter interactions below the current experimental constraints in the $[1.2, 3.6]$ GeV/c$^2$ WIMP mass range., 11 pages, 12 figures

Abstract: We use an integrative taxonomic approach to revise the genus Anisopteromalus. In particular, we apply multivariate ratio analysis (MRA), a rather new statistical method based on principal component analysis (PCA) and linear discriminant analysis (LDA), to numerous body measurements and combine the data with those from our molecular analysis of Cytb and ITS2 genetic markers (on a subset of species) and all available published data on morphology, karyology, behaviour, host associations and geographic distribution. We demonstrate that the analysis of quantitative characters using MRA plays a major role for the integration of name-bearing types and thus for the association of taxa with names. Six species are recognized, of which two are new: A. cornis Baur sp.n. and A. quinarius Gokhman & Baur sp.n. For Anisopteromalus calandrae (Howard), a well-known, cosmopolitan parasitoid of stored-product pests, we have selected a neotype to foster continuity and stability in the application of this important name. The species was sometimes confused with the related A. quinarius sp.n., another cosmopolitan species that is frequently encountered in similar environments. We also show that several species originally described or later put under Anisopteromalus actually belong to different genera: Cyrtoptyx camerunus (Risbec) comb.n.; Meraporus glaber (Szelenyi) comb.n.; Dinarmus schwenkei (Roomi, Khan & Khan) comb.n. Neocatolaccus indicus Ayyar & Mani is confirmed as a junior synonym of Oxysychus sphenopterae (Ferriere) syn.n. and Anisopteromalus calandrae brasiliensis (Domenichini) stat.rev. must be considered as a valid but doubtful taxon.

Peace & justice, Arnold tongue, Ordinary differential equation, complex variables, symbols, Adjacency list, Analysis, Sign (mathematics)
Abstract: We investigate two-parametric family of non-autonomous ordinary differential equations on the two-torus $$\dot x=\frac{dx}{dt}=\nu\sin x + a + s \sin t, \ a,\nu,s\in\rr; \ \nu\neq0 \text {is fixed},$$ that model the Josephson effect from superconductivity. We study its rotation number as a function of parameters $(a,s)$ and its {\it Arnold tongues}: the level sets of the rotation number that have non-empty interior. Its Arnold tongues have many non-typical properties: they exist only for integer rotation numbers (V.M.Buchstaber, O.V.Karpov, S.I.Tertychnyi (2010); Yu.S.Ilyashenko, D.A.Ryzhov, D.A.Filimonov (2011)); their boundaries are given by pairs of analytic curves (V.M.Buchstaber, O.V.Karpov, S.I.Tertychnyi (2004, 2012)). Numerical experiments and theoretical investigations (V.M.Buchstaber, O.V.Karpov, S.I.Tertychnyi (2006); A.V.Klimenko and O.L.Romaskevich (2012)) show that each Arnold tongue forms an infinite chain of adjacent domains separated by adjacency points and going to infinity in asymptotically vertical direction. Recent numerical experiments had also shown that the adjacencies of each Arnold tongue have one and the same integer abscissa $a$ equal to the corresponding rotation number. We prove this fact for every fixed $\nu$ with $|\nu|\leq1$. In the general case we prove a weaker statement: the abscissa of each adjacency point is integer; it has the same sign, as the rotation number; its modulus is no greater than that of the rotation number. The proof is based on the representation of the differential equations under consideration as projectivizations of complex linear differential equations on the Riemann sphere (V.M.Buchstaber, O.V.Karpov, S.I.Tertychnyi (2004); R.L.Foote (1998); Yu.S.Ilyashenko, D.A.Ryzhov, D.A.Filimonov (2011)), and the classical theory of complex linear equations., Comment: In Russian (18 pages, 1 figure); brief summary in English (7 pages)

Abstract: Mixed-ligand ruthenium(II) complex with 2,2′-bipyridine and 1,10-phenanthroline-3,8-dicarboxylic acid with the composition [Ru(phen-C)(bpy)2]Cl2·5H2O (bpy = 2,2′-bipyridine, phen-C = 1,10-phenantroline-3,8-dicarboxylic acid) has been synthesized and characterized by spectral data. The complex has been tested as photocatalyst in aerobic oxidation reactions, including transformation of arylboronic acids to phenols, primary amines to imines, and sulfides to sulfoxides in aqueous medium. The possibility of regeneration of the catalyst in the oxidation of sulfides has been demonstrated.
