2. On the collapse in fourth order gravities

Author

Subjects
General Relativity and Quantum Cosmology
Abstract

The gravitational collapse in fourth order theories of gravity defined by an arbitrary action of the scalar curvature shows significant deviations with General Relativity. The presence of a new scalar mode produces a higher initial contraction that favors the reduction of the collapsing time. However, depending on the particular model, there are fundamental differences when the modifications to the General Relativity collapse leave the linear regime. These analyses can be used to exclude an important region of the parameter space associated with alternative gravitational models., Comment: 4 pages, 2 figures, Contribution to the Proceedings of Spanish Relativity Meeting ERE2011, Madrid 2011

Abstract

We study the gravitational collapse in modified gravitational theories. In particular, we analyze a general $f(R)$ model with uniformly collapsing cloud of self-gravitating dust particles. This analysis shares analogies with the formation of large-scale structures in the early Universe and with the formation of stars in a molecular cloud experiencing gravitational collapse. In the same way, this investigation can be used as a first approximation to the modification that stellar objects can suffer in these modified theories of gravity. We study concrete examples, and find that the analysis of gravitational collapse is an important tool to constrain models that present late-time cosmological acceleration., Comment: 10 pages, 6 figures

Abstract

Triple negative breast cancer (TNBC) is the breast cancer subtype with the worst prognosis and still lacks a targeted therapy. In this study, we found increased ERK phosphorylation in TNBC cell lines and an important role for ERK in sustaining the migration of TNBC cells. Although ROS have been suggested to have an important role in sustaining MAPK signaling, antioxidant treatment increased ERK phosphorylation, probably suggesting increased invasive potential. Interestingly, treatment with PD0325901 (PD), a MEK inhibitor, decreased ROS levels in TNBC cells and decreased mitochondrial fragmentation in the MDAMB231 cell line. Our data supports an important role for MEK/ERK in TNBC, sustaining cellular migration, regulating mitochondrial dynamics and ROS production in this breast cancer subtype.

Abstract

20 pages, 15 figures, 4 tables.-- Data Availability Statement: All data are available under request to the first auth, Measuring the nearshore bathymetry is critical in coastal management and morphodynamic studies. The recent advent of Unmanned Aerial Vehicles (UAVs), in combination with coastal video monitoring techniques, allows for an alternative and low cost evaluation of the nearshore bathymetry. Camera calibration and stabilization is a critical issue in bathymetry estimation from video systems. This work introduces a new methodology in order to obtain such bathymetries, and it compares the results to echo-sounder ground truth data. The goal is to gain a better understanding on the influence of the camera calibration and stabilization on the inferred bathymetry. The results show how the proposed methodology allows for accurate evaluations of the bathymetry, with overall root mean square errors in the order of 40 cm. It is shown that the intrinsic calibration of the camera, related to the lens distortion, is the most critical aspect. Here, the intrinsic calibration that was obtained directly during the flight yields the best results, This research was funded by the Spanish Government (MINECO/MICINN/FEDER) grant numbers RTI2018-093941-B-C32, and RTI2018-093941-B-C33, PID2019-109143RB-I00 and FEDER-UCA18-107062.

Abstract

Purpose To compare the local recurrence rate and overall survival between patients with circumferential resection margin (CRM) involvement by direct tumor spread and by a tumor within a lymph node. Methods A total of 776 patients diagnosed with rectal cancer underwent rectal resection. Patients with CRM involvement by direct tumor spread were named group A. CRM involvement by tumor within a lymph node formed group B. Patient data, including sex, age, pT, pN, stage I-III versus IV, neoadjuvant radiotherapy, adjuvant chemotherapy, carcinoembryonic antigen, primary tumor location, lymph node retrieval, and need for abdominoperineal resection, were compared between both groups. Results In total, 10.5% of the patients had CRM involvement. Of these, in 57 cases (7.3%), it was by direct tumor spread and in 19 cases (2.4%) by tumor within a lymph node. Other types of CRM involvement were found in six patients. With a mean follow-up of 32.9 months, 18 patients from group A (31.5%) and one patient from group B (5.2%) suffered a local recurrence. Local recurrence-free survival was significantly higher in patients from group B (P = 0.049). Patients in stage I-III (P = 0.037) and from group B ( P = 0.049) had better overall survival. Conclusion Patients with CRM involvement by tumor within a lymph node have a low risk of local recurrence and better overall survival than patients with CRM involvement by direct tumor spread.

Abstract

There is growing evidence that the frequency and magnitude of extreme weather events may be increasing in conjunction with climate change. This means that many communities will encounter phenomena, such as extreme storm surge events, never before experienced by local residents. The tragic effects of Typhoon Haiyan on the city of Tacloban, Philippines, in November 2013 were attributed, in part, to the inability of routine technical bulletins to communicate the unprecedented nature of the predicted storm surge. In response, the authors construct a relational model of risk communication that suggests that narrative messages that simulate direct face-to-face communication may be more effective in spurring action. Conducting a postevent target audience study in the city of Tacloban, the authors tested the relative effectiveness of narrative-based versus technical message designs on residents who chose not to evacuate during the typhoon. Results show increased effectiveness of the narrative design vis-à-vis intent to evacuate, self-relevance and vividness of the message, and perceived authority of the message source. The study also explored factors behind noncompliance with evacuation advisories. The research supports the relational model, which captures insights from recent research on evacuation and emergency preparedness for extreme hazard events. It supports a broader effort to democratize risk communication and, in so doing, increase people’s sense of agency in preparing for these events.

Abstract

Senecio L., the largest genus in the tribe Senecioneae (Asteraceae), contains a significant number of taxonomic difficulties, given that its boundaries are not clearly defined and species identification is sometimes complicated. A study was carried out to evaluate the importance of micromorphological characters in the resolution of such taxonomic problems. The study included 18 South American taxa from series Xerosenecio, Corymbosi and Otoperi. The characters studied include the stigmatic surface and apices of the stylar branches, the filament collar, base and appendages of the anthers, and the pollen shape, size, sculpture and aperture. The microcharacters of the stamens (filaments and anthers) and the presence of margo in the pollen provide taxonomically useful traits for the differentiation of related taxa and infraspecific entities in the genus Senecio. The mesoaperture in the pollen grain in eight Argentinean taxa of Senecio is recorded for the first time. Finally, unique floral microcharacters (sagittate anther base) and palynological features (cavea not evident, long spines) in S. otites were observed.

Abstract

We report on a measurement of the attenuation length for the scintillation light in the tonne size liquid argon target of the ArDM dark matter experiment. The data was recorded in the first underground operation of the experiment in single-phase operational mode. The results were achieved by comparing the light yield spectra from 39Ar and 83mKr to a description of the ArDM setup with a model of full light ray tracing. A relatively low value close to 0.5 m was found for the attenuation length of the liquid argon bulk to its own scintillation light. We interpret this result as a presence of optically active impurities in the liquid argon which are not filtered by the installed purification systems. We also present analyses of the argon gas employed for the filling and discuss cross sections in the vacuum ultraviolet of various molecules in respect to purity requirements in the context of large liquid argon installations.

Abstract

Autophagy is an intracellular recycling process active in eukaryotic cells which involves the formation of an autophagosome that delivers cytoplasmic components to the lysosome for degradation. This process occurs at low rates under basal conditions, but it can be induced by diverse stress conditions such as starvation, hypoxia or metabolic disorders. Autophagic flux can also be enhanced in response to hormones, including leptin. Leptin is considered a pro-tumorigenic protein whose circulating levels have been related to a bad prognosis in obese breast cancer patients. It has been recently demonstrated that leptin can induce autophagy in cancer cell lines from different tissues, suggesting that autophagy could modulate the pro-tumorigenic effects associated with leptin. In this study, the role of autophagy in leptin-induced proliferation, migration, apoptosis and ERK phosphorylation in breast cancer cell lines was evaluated. Methods: MCF7 estrogen receptor positive and MDA-MB-231 triple negative breast cancer cell lines were used. MCF7 and MDA-MB-231 cell lines were stimulated with 400 and 50 ng/ml of leptin, respectively. Autophagy was assessed by LC3-II and p62 protein levels by western blot, and autophagosome formation by fluorescence microscopy. Proliferation and migration were assessed by real-time microscopy in an IncuCyte analyzer; and cell death was evaluated by fluorescence analysis of caspase activity. Changes in ERK phosphorylation were measure by western blot. Results: Leptin increased autophagy in MCF7 cells but not in triple negative MDA-MB-231 cells. In MCF7 cells, autophagy inhibition reduced leptin-induced cell proliferation, changes associated to a mesenchymal morphology, cell migration, and ERK activation. In MDA-MB-231 cells, autophagy inhibition reduced proliferation and increased apoptosis independently of leptin treatment. In both cell lines, leptin-induced migration and ERK phosphorylation were reduced by the inhibition of autophagy. Conclusion: Autophagy was important for increased cancer cell migration induced by leptin and for the maintenance of ERK phosphorylation. Our data suggest a potential use for the inhibition of autophagy in breast cancer associated with obesity. Citation Format: Alin García Miranda, Karen A. Solano Alcalá, José B.

Abstract

Se ha realizado un estudio para la validación biofarmacéutica del preparado de liberación sostenida de diclofenaco, Dolotrén® Retard (DA) respecto a otro con cubierta entérica, Dolotrén® (D). Para ello se determinó la biodisponibilidad de ambas formulaciones administradas por vía oral, en dosis única y múltiples. Participaron 9 voluntarios sanos que recibieron, de manera aleatoria y cruzada, 100 mg de D y 100 mg de DA, primero en dosis única y luego cada día, durante 15 días. Para la determinación analítica de diclofenaco se extrajeron muestras de sangre a intervalos de tiempo definidos, el día de la dosis única y los días 3°, 7° y 15° de la administración de dosis múltiples. Se determinaron los parámetros cinéticos: Cmax, tmax, a y p, aclaramiento, ka, área bajo la curva y biodisponibilidad absoluta y relativa. Se pone de manifiesto la gran variabilidad interindividual existente en las características cinéticas del diclofenaco sódico, tanto cuando se le administra por vía endovenosa como por vía oral. El período de latencia (t1a9) de DR es de 0,4 h, más corto que el de O (2,2 h), indicando una más precoz absorción en tramos altos del tracto gastrointestinal. La tmax, también fue más corta para DR (1,9 h) que para D (4,3 h). La Cmax alcanzada con D fue más alta que con DR. Los procesos de desaparición del diclofenaco sódico del plasma son significativamente más lentos con DR que con D (t112P de 18,1 h y 2,5 h, respectivamente). Ello trae como consecuencia el mantenimiento de niveles plasmáticos cuantificables durante al menos 24 horas después de la administración de DA, lo que no ocurre con D. La biodisponibilidad absoluta de los dos preparados es de aproximadamente un 80%, con grandes variaciones interindividuales, no se han podido demostrar diferencias significativas entre los dos preparados. La biodisponibilidad relativa entre DR y D fue del 91,5 %. Con ninguno de los preparados se produce acumulación cuando se administra en dosis repetidas, D cada 12 horas y DA cada 24 horas, ni cambian sus características farmacocinéticas. La tolerancia clínica y biológica de ambos preparados fue excelente, a las dosis utilizadas y durante el período de tiempo estudiado. Dolotrén® Retard se absorbe por vía oral más pronto que Dolotrén® y mantiene niveles plasmáticos durante más tiempo, lo que permite su administración una sola vez al día, con una menor incidencia de efectos indeseables relacionados con la Cmax.

Abstract

In this study a video-monitoring system was used to analyze the presence of mesoforms during a time period of five years in the urban beach of La Victoria, Cádiz, Spain. This technique allowed the generation of plan views using an improved version of ULISES software. The presence and spatiotemporal variability of the most common mesoforms, such as bars and cusps, was identified in all the plan views. Furthermore, the morphodynamic state of the beach was investigated in combination with local hydrodynamic data. The cusp systems were also studied by means of wavelet analyses and different theories on cusps formation were tested. The presence of the investigated features was related to the wave energy and its seasonal variations. The behavior of the mesoforms demonstrated the important role of a subtidal rocky outcrop in the nearshore processes. The results also show that bars and cusps as indicators of the nearshore processes are a useful tool for the macroscopic analysis of surf zone dynamics in dissipative beaches, This research was funded by the Spanish Ministry of Economy and Competitiveness under ADACOSTA research project, grant number CGL2014-53153-R.

Montes, J.; Benavente, J.; Silva, R.; Plomaritis, T.A., and Del Rio, L., 2020. Simplified method for the identification of erosion and flooding hazard hotspots on sandy beaches. In: Malvarez, G. and Navas, F. (eds.), Global Coastal Issues of 2020. Journal of Coastal Research, Special Issue No. 95, pp. 1206-1210. Coconut Creek (Florida), ISSN 0749-0208. The exponential growth in coastal population over the recent decades has intensified the pressure on coastal zones and has placed them on the focus of the scientific community, particularly in the context of climate change. This work presents a reliable method to easily identify current and future hazard hotspots on sandy beaches in monitored coastal areas. Hotspots are defined as areas with high erosion and flooding hazard, which require detailed further study. The methodology is based into the application of WAPO (Wave Propagation On the Coast) model and DSAS (Digital Shoreline Analysis System) tool. WAPO model propagates monochromatic wave trains over a variable bottom and extracts the energy flux on the coast, taking into account refraction, diffraction, shoaling, reflection and energy dissipation. DSAS tool calculates rates of shoreline change from multiple historical shoreline positions. The method was applied in La Atunara beach in the South of Spain, influenced by the presence of anthropic structures and a complex bathymetry. Wave data used in the models were extracted by a joint probability analysis of wave height, period and direction for modal and storm conditions in the zone. Additionally, synthetic cases were generated for assessing climate change impact by modifying mean sea level parameters according to the IPCC scenarios. Results show that this methodology provides a simplified assessment of hotspots that allows focusing on the most vulnerable areas. This avoids the use of more complex and time-consuming models in large areas, allowing efforts to be concentrated on the identified hotspots.

Abstract

The coast of Cadiz province (SW Spain) constitutes a complex system with a wide variety of hydrodynamic and geological-geomorphological conditions. Morphodynamic behaviour of beaches in this area shows more dissipative states in the Atlantic coast and more reflective states in the Mediterranean coast. Recent shoreline trends indicate a relatively stable behaviour along most part of Cadiz coast over the last decades, although there are numerous sectors with a clearly erosive trend, mainly in the Northern half of the province. The great spatial and temporal variability of shoreline changes observed is related to the heterogeneity of the coast, as well as to the diversity of factors contributing to erosion processes on each sector. Several coastal hazard hotspots appear along the study zone, mostly related to extreme meteorological events and short-term trends, namely coastal erosion and flooding. The frequency and severity of the risks derived from these hazards have increased over the last decades, mainly due to the increased anthropogenic pressure and urban development on the coast.

Abstract

This chapter examines the origin, evolution and present state of the coastal dunes along the South Atlantic Spanish coast around the Strait of Gibraltar. Wind regime in the zone is strongly affected by the North Atlantic Oscillation (NAO). Low or negative NAO index values give rise to the prevalence of westerly humid winds, while during periods with a positive NAO index easterly, dry winds prevail. Several Holocene and historical aeolian phases have been identified in the zone, represented by different aeolian deposits, many of them containing archaeological remains. The oldest one dates to shortly after the mid-Holocene eustatic maximum. During historical times dune-building episodes were associated with a higher frequency and persistence of easterly winds. During the 20th century, and especially in the last few decades, the prevalence of positive values of the NAO index has favoured the growth and advance of mobile dunes in the vicinity of the Strait of Gibraltar. In contrast, dune ridges associated with westerly winds are much less mobile or stable and form shore-parallel ridges covered by vegetation. In the Atlantic side of the Strait, environmental health of coastal dunes is satisfactory, especially those included in the Strait of Gibraltar Natural Park, where more effective protection measures are applied. The Mediterranean side is characterized by a dense population and intense human interventions, leading to erosion problems. Climate change predictions for the next decades suggest an increase in the frequency and intensity of easterly-Levante winds in the Strait. This situation would favour the reinforcement and growth of the Levante-derived dunes around the Strait, and perhaps recovery of the small dunes existing in the Mediterranean side.

Abstract

We report measurements of the inclusive J/ψ yield and average transverse momentum as a function of charged-particle pseudorapidity density dNch/dη in p–Pb collisions at sNN=5.02TeV with ALICE at the LHC. The observables are normalised to their corresponding averages in non-single diffractive events. An increase of the normalised J/ψ yield with normalised dNch/dη, measured at mid-rapidity, is observed at mid-rapidity and backward rapidity. At forward rapidity, a saturation of the relative yield is observed for high charged-particle multiplicities. The normalised average transverse momentum at forward and backward rapidities increases with multiplicity at low multiplicities and saturates beyond moderate multiplicities. In addition, the forward-to-backward nuclear modification factor ratio is also reported, showing an increasing suppression of J/ψ production at forward rapidity with respect to backward rapidity for increasing charged-particle multiplicity. © 2017 The Author

Abstract

Palynological studies contribute to understanding the taxonomy, phylogeny and ecology of the Asteraceae and other families. In this study, pollen morphology and ultrastructure oft he exine of Senecio bergii Hieron. were studied using light, scanning and transmission electron microscopy. The pollen of this species is prolate-spheroidal, it has a Senecioid pattern on the exine and an apertural system composed of three apertures (ecto-, meso- and endoapertures). This pollen type is defined as tricolpororate due to the triple apertural system. This is the first description of the ultrastructure of the apertural system of the pollen of Argentine species of Senecio. The presence of mesoapertures and the description of the ultrastructure of the pollen of Senecio bergii contribute to the general knowledge of the Senecio pollen type, as well as to the taxonomic delimitation of species in this genus.

Abstract

Large size detectors based on Cs2LiYCl6:Ce (CLYC) are capable of performing a combined $\gamma$-ray and neutron spectrometry and constitute a promising technology for a wide range of applications in nuclear and high energy physics. Due to their novelty, the comprehensive characterization of the performance of individual CLYC detectors is of great importance for determining their range of applicability. In this work we report on a wide series measurements performed with a commercial 2"x2" CLYC crystal. Good energy and timing resolution values of 4.7% (@ 662 keV) and 1340 ps (FWHM), respectively, were achieved, and a neutron/$\gamma$ separation figure of merit value of 4.2 was obtained. A dedicated measurement for investigating the intrinsic background of the detector was performed at the Laboratorio Subterr\'aneo de Canfranc (Spain). It evidenced a sizeable contamination in the detector materials which poses limits in the use of CLYC in low background experiments. In addition, detailed Monte Carlo simulations with the GEANT4 toolkit were performed for modeling the response function of the CLYC detector to gamma-rays. An excellent agreement with the experimental data has been achieved., Comment: 30 pages, 22 figures. Submitted to Nuclear Instruments and Methods in Physics Research A

Abstract

We present the first measurement of the two-particle transverse momentum differential correlation function, P-2 = / < p(T)>(2), in Pb-Pb collisions at root s(NN) = 2.76 TeV. Results for P-2 are reported as a function of the relative pseudorapidity (Delta eta) and azimuthal angle (Delta phi) between two particles for different collision centralities. The Delta phi dependence is found to be largely independent of Delta eta for broken vertical bar Delta eta broken vertical bar >= 0.9. In the 5% most central Pb-Pb collisions, the two-particle transverse momentum correlation function exhibits a clear double-hump structure around Delta phi=pi (i. e., on the away side), which is not observed in number correlations in the same centrality range, and thus provides an indication of the dominance of triangular flow in this collision centrality. Fourier decompositions of P-2, studied as a function of the collision centrality, show that correlations at broken vertical bar Delta eta broken vertical bar >= 0.9 can be well reproduced by a flow ansatz based on the notion that measured transverse momentum correlations are strictly determined by the collective motion of the system.

Abstract

We present the first azimuthally differential measurements of the pion source size relative to the second harmonic event plane in Pb-Pb collisions at a center-of-mass energy per nucleon-nucleon pair of sNN=2.76 TeV. The measurements have been performed in the centrality range 0%-50% and for pion pair transverse momenta 0.2

Abstract

We present the charged-particle pseudorapidity density in Pb–Pb collisions at sNN=5.02 TeV in centrality classes measured by ALICE. The measurement covers a wide pseudorapidity range from −3.5 to 5, which is sufficient for reliable estimates of the total number of charged particles produced in the collisions. For the most central (0–5%) collisions we find 21400±1300, while for the most peripheral (80–90%) we find 230±38. This corresponds to an increase of (27±4)% over the results at sNN=2.76 TeV previously reported by ALICE. The energy dependence of the total number of charged particles produced in heavy-ion collisions is found to obey a modified power-law like behaviour. The charged-particle pseudorapidity density of the most central collisions is compared to model calculations — none of which fully describes the measured distribution. We also present an estimate of the rapidity density of charged particles. The width of that distribution is found to exhibit a remarkable proportionality to the beam rapidity, independent of the collision energy from the top SPS to LHC energies. © 2017 The Author(s)

Abstract

The transverse momentum distributions of the strange and double-strange hyperon resonances (Σ (1385) ±, Ξ (1530) 0) produced in p–Pb collisions at sNN=5.02 TeV were measured in the rapidity range - 0.5 < yCMS< 0 for event classes corresponding to different charged-particle multiplicity densities, ⟨ dNch/dηlab⟩. The mean transverse momentum values are presented as a function of ⟨ dNch/dηlab⟩ , as well as a function of the particle masses and compared with previous results on hyperon production. The integrated yield ratios of excited to ground-state hyperons are constant as a function of ⟨ dNch/dηlab⟩. The equivalent ratios to pions exhibit an increase with ⟨ dNch/dηlab⟩ , depending on their strangeness content. © 2017, CERN for the benefit of the ALICE collaboration.

Abstract

The production of K*(892)(0) and phi(1020) mesons in proton-proton (pp) and lead-lead (Pb-Pb) collisions at root sNN = 2.76 TeV has been analyzed using a high luminosity data sample accumulated in 2011 with the ALICE detector at the Large Hadron Collider (LHC). Transverse momentum (p(T)) spectra have been measured for K*(892)(0) and phi(1020) mesons via their hadronic decay channels for p(T) up to 20 GeV/c. The measurements in pp collisions have been compared to model calculations and used to determine the nuclear modification factor and particle ratios. The K*(892)(0)/K ratio exhibits significant reduction from pp to central Pb-Pb collisions, consistent with the suppression of the K*( 892)(0) yield at low pT due to rescattering of its decay products in the hadronic phase. In central Pb-Pb collisions the pT dependent phi(1020)/p and K*(892)0/p ratios show an enhancement over pp collisions for pT approximate to 3 GeV/c, consistent with previous observations of strong radial flow. At high pT, particle ratios in Pb-Pb collisions are similar to those measured in pp collisions. In central Pb-Pb collisions, the production of K*(892)(0) and phi(1020) mesons is suppressed for p(T) > 8 GeV/c. This suppression is similar to that of charged pions, kaons, and protons, indicating that the suppression does not depend on particle mass or flavor in the light quark sector.

Abstract

Chenopodium album is a very polymorphic, cosmopolitan, annual herb that grows spontaneously in modified soils in wasteland in the outlying urban zones of Bahia Blanca. In this city, the flowering period is mainly during February and March, which coincides with the highest concentrations of this pollen type in the atmosphere of the city. The objective of this study was to characterize the pollen grains of Chenopodium album, both morphologically and immunochemically, that were obtained from three different zones in the urban area of Bahia Blanca. Samples were collected from the three separate zones in the city that were far apart. The structure and morphology of the grains were analyzed using light and electron microscopy. The protein and antigenic profiles were studied with Tricine-SDS-PAGE and western blot with a polyclonal rabbit serum, respectively. The morphological analysis showed significant differences in relation to the diameters of the pollen grains in one of the studied areas. Differences in the protein expression were seen for the same area although the antigenic profile was conserved. The variations in the morphology and the protein profile may be caused by the effect of environmental conditions on the pollen, and the presence of urban contaminants from vehicular traffic.

Abstract

A study of the dynamics of the positive charges in liquid argon has been carried out in the context of the future massive time projection chambers proposed for dark matter and neutrino physics. Given their small mobility coefficient in liquid argon, the ions spend a considerably longer time in the active volume with respect to the electrons. The positive charge density can be additionally increased by the injection, in the liquid volume, of the ions produced by the electron multiplying devices located in gas argon. The impact of the ion current on the uniformity of the field has been evaluated as well as the probability of the charge signal quenching due to the electron-ion recombination along the drift. The study results show some potential concerns for massive detectors with drift of many meters operated on surface., Submitted to Astroparticle Physics

Abstract

Nowadays, Dark Matter search constitutes one of the most challenging scientific activity. During the last decades several detectors have been developed to evidence the signal of interactions between Dark Matter and ordinary matter. The Argon Dark Matter detector, placed in the Canfranc Underground Laboratory in Spain is the first ton-scale liquid-Ar experiment in operation for Dark Matter direct detection. In parallel to the development of other engineering issues, computational methods are being applied to maximize the exploitation of generated data. In this work, two algorithms based on decision trees —Generalized Boosted Regression Models and Random Forests— are employed to reconstruct the position of the interaction in Argon Dark Matter detector. These two algorithms are confronted to a Montecarlo data set reproducing the physical behaviour of Argon Dark Matter detector. In this work, an in-depth study of the position reconstruction of the interaction is performed for both algorithms, including a study of the distribution of errors.

Abstract

Light sheet optical microscopy on strontium aluminate nanoparticles (SrAl2 O4 NPs)1 codoped with Eu2+ and Dy3+ was used for cancer cell tagging and tracking. The nanoparticles were synthesized by urea-assisted combustion with optimized percentage values of the 2 codoping rare-earth ions for cell viability and for lower cytotoxic effects. The optical properties of these materials showed an excitation wide range of wavelengths (λexc = 254-460 nm), a broad emission band (λem = 475-575 nm) with the maximum centered wavelength at 525 nm and a half lifetime within the seconds regime. The feasibility to measure the nanoparticle luminescence under the selective plane illumination configuration was studied by immersing the nanoparticles in 1% Agarose. The potential applicability of the synthesized nanophosphors for cancer cell tagging was demonstrated by using in vitro experiments with human breast adenocarcinoma MCF-7 cells. A single MCF-7 cell observed by the use of light sheet microscopy with UV excitation. The cell has been bio-labeled with FA-SrAl2 04 : Eu2+ , Dy3+ NPs and 4',6-diamidino-2-phenylindole, dihydrochloride for nucleus identification.

Abstract

Galectin-1 (Gal-1) is important in immune function and muscle regeneration, but its expression and localization in adult tissues and primary leukocytes remain unclear. To address this, we generated a specific monoclonal antibody against Gal-1, termed alphahGal-1, and defined a sequential peptide epitope that it recognizes, which is preserved in human and porcine Gal-1, but not in murine Gal-1. Using alphahGal-1, we found that Gal-1 is expressed in a wide range of porcine tissues, including striated muscle, liver, lung, brain, kidney, spleen, and intestine. In most types of cells, Gal-1 exhibits diffuse cytosolic expression, but in cells within the splenic red pulp, Gal-1 showed both cytosolic and nuclear localization. Gal-1 was also expressed in arterial walls and exhibited prominent cytosolic and nuclear staining in cultured human endothelial cells. However, human peripheral leukocytes and promyelocytic HL60 cells lack detectable Gal-1 and also showed very low levels of Gal-1 mRNA. In striking contrast, Gal-1 exhibited an organized cytosolic staining pattern within striated muscle tissue of cardiac and skeletal muscle and colocalized with sarcomeric actin on I bands. These results provide insights into previously defined roles for Gal-1 in inflammation, immune regulation and muscle biology.

Abstract

Summary. The effects of a new triazole antifungal agent, saperconazole, on the morphology of Candida albicans were studied by scanning and transmission electron microscopy. An inoculum of 106 CFU ml-1 was exposed to saperconazole at 1 and 10 μg ml-1 and at different times up to 24 h samples were removed for microscopic observations. The antifungal agent caused the yeasts to become round and turgescent and to cluster; budding appeared to be affected also, as seen by scanning electron microscopy. Transmission electron microscopy showed a thickened wall, the presence of intraparietal electron-dense vesicles and of multilamellae near the plasma membrane. Zusammenfassung. Die Wirkung des neuen Triazol-Antimyzetikums Saperconacol auf die Mor-phologie von Candida albicans wurde raster- und transmissionselektronenmikroskopisch untersucht. Ein Inoculum von 106 Kolonie-bildenden Einhei-ten/ml wurde Saperconacol in den Konzentrationen von 1 und 10 μg ml-1 exponiert. Zu unterschiedli-chen Expositionszeiten bis maximal 24 h wurden Stichproben zur ultrastrukturellen Untersuchung gewonnen. Die Einwirkung des Antimyzetikums zeigte sich in Abrundung, Turgeszenz und Klumpenbildung der Hefezellen; ebenso war die Knos-pung betroffen, wie rasterelektronenmikroskopisch gezeigt werden konnte. Die Transmissionselektro-nenmikroskopie zeigte eine verdickte Zellwand, das Auftreten elektronendichter Vesikel in der Zellwand und vielschichtige Lamellen in der Nahe der cyto-plasmatischen Membran.

Abstract

Summary: The susceptibility of several strains of Candida and Tomlopsis to saperconazole, a new triazole antifungal compound, was compared to that of ketoconazole. The MICs of the two antifungal agents were determined against 70 strains of Candida albicans, 10 strains of C. guilliermon-dii, 10 strains of C. krusei, 10 strains of C. parapsilosis, 10 strains of C. pseudotropicalis, 10 strains of C. tropicalis and 15 strains of Torulopsis glabrata. The fungi-static activity was evaluated by the agar dilution method using BHI and casitone media after incubation for 48 hours at 28–30°C. The in vitro activity of saperconazole was similar to that of ketoconazole for most of the Candidaspp. tested except for C. krusei in particular. An MIC of ≤ 3.12 μg/ml for saperconazole was found with 92 % of the C albicans strains tested. In contrast, T. glabrata was more susceptible to ketoconazole. Zusammenfassung: Die Empfindlichkeit fur Saperconazol, einem neuen Triazol, und Ketoconazol wurde an Candida- und Torulopsis Stammen vergleichend in vitro gepruft. Die MHK der beiden Antimyzetika wurde an 70 Candida albicans-, 10 C. guilliermondii-, 10 C. krusei-, 10 C. parapsilosis-, 10 C pseudotropicalis-, 10 C. tropicalisund 15 Torulopsis glabrata-Satammen bestimmt. Die fungistatische Aktivitat wurde mit der Agardilutionsmethode (Herz-, Hirn- und Casitone-Agar) nach 48 h Bebrutung bei 28–30°C erfast. Die Aktivitat von Saperconazol in vitro war fur die meisten Candida-Arten (auser C. krusei) derjeniger von Ketoconazol ahnlich. Eine MHK ≤ 3.12 μg/ml Saperconazol wurde bei 92 % der gepruften C. albicans-Stamme gefunden. Im Gegensatz hierzu war T. glabrata empfindlicher fur Ketoconazol.

Abstract

The Argon Dark Matter (ArDM) experiment consists of a liquid argon (LAr) time projection chamber (TPC) sensitive to nuclear recoils, resulting from scattering of hypothetical Weakly Interacting Massive Particles (WIMPs) on argon targets. With an active target mass of 850 kg ArDM represents an important milestone towards developments for large LAr Dark Matter detectors. Here we present the experimental apparatus currently installed underground at the Laboratorio Subterráneo de Canfranc (LSC), Spain. We show data on gaseous or liquid argon targets recorded in 2015 during the commissioning of ArDM in single phase at zero E-field (ArDM Run I). The data confirms the overall good and stable performance of the ArDM tonne-scale LAr detector., Journal of Cosmology and Astroparticle Physics, 2017 (3), ISSN:1475-7516

Abstract

The Argon Dark Matter experiment is a ton-scale double phase argon Time Projection Chamber designed for direct Dark Matter searches. It combines the detection of scintillation light together with the ionisation charge in order to discriminate the background (electron recoils) from the WIMP signals (nuclear recoils). After a successful operation on surface at CERN, the detector was recently installed in the underground Laboratorio Subterráneo de Canfranc, and the commissioning phase is ongoing. We describe the status of the installation and present first results from data collected underground with the detector filled with gas argon at room temperature., Journal of Instrumentation, 8 (9), ISSN:1748-0221

Abstract

Introduction: During climacteric, women experience physical and psychological changes due to declining ovarian estrogen. The cardiovascular system is one of those affected. However, there are not sufficient studies of the effects of the climacteric on heart function. The fluctuations of the heart rate are the most common way to analyze the changes in heart function. Materials and Methods: In this work, ten minutes of ECG signal at rest were recorded for a group of 57 healthy climacteric females. In this study, two methodologies were used to analyze the ECG signal: Heart Rate Variability (HRV) and Detrended Fluctuation Analysis (DFA). Results and Discussion: Heart rate variability and detrended fluctuation analysis can be used to monitor changes of cardiovascular system during the climacteric stages (pre-, peri-, and postmenopausal). Both methodologies are sensitive almost at the same level to cardiovascular changes observed during the peri- menopausal stage.

Abstract

Introduction: Cardiovascular response to acute stress is a widely addressed topic because there is a clinical association of psychological and physical stress with high risk for stroke and cardiovascular events and also with the increase of morbid-mortality of the population. The Heart Rate Variability (HRV) is one of the most common methods of evaluation although some other alternatives have been emerged to complement the information about this response. One of these alternatives is the Detrended Fluctuation Analysis (DFA). Materials and Methods: Here we present a comparison between the results from HRV via the area under low frequency spectrum versus those from DFA via the scaling parameter alpha. Fifty seven healthy women, aging between 40 and 60 years old, were evaluated according to the following paradigm: 1) ECG in basal state (ten min); 2) ECG during psychological stress test (Stroop test, 3 min); and 3) ECG in basal state (three min). Results and Discussion: Heart rate variability, and detrended fluctuation analysis can be used, in short term recordings, to evaluate psychological stress response to Stroop test. HRV and DFA are sensitive to different stages of the paradigm used in this study, being the HRV which gives a fast reaction to the psychological stress, but DFA gives information about a more delayed response, at the last step of the paradigm (resting state).

Abstract

We present an experiment for demonstrating the principle of plasma beat-wave acceleration. The beating of two Nd-laser pulses creates a relativistic plasma wave in a deuterium plasma. Electrons at an energy of 3 MeV are injected into the plasma. We observe several hundred electrons accelerated up to 3.7 MeV. This paper is mainly devoted to the description of the experimental apparatus. In the design of the apparatus, we gave particular attention to efficient electron injection and to background noise suppression. We present also some preliminary results of electron acceleration experiments.

Abstract

Persistent luminescence strontium aluminate nanoparticles co-doped with Eu2+ and Dy3+ were prepared by urea-assisted combustion synthesis. Different percentages of co-dopants were evaluated in order to optimize luminescence of the nanophosphor. Luminescence measurements showed that excitation of this green-emitting phosphor occurred within a wide range of wavelengths (254 – 460 nm) while the half-life time of persistent luminescence laid within the seconds regime. Presence of Dy3+ as the co-dopant enhanced the green emission in this interval of time, and the entire decay time occurred in minutes. Crystallinity and morphology were evaluated by X-ray diffraction (XRD) and transmission electron microscopy (TEM), respectively. Strontium aluminate co-doped with 1%Eu, and 1%Dy, and 1%Eu, and 3%Dy emitted an intense green signal and long decay time. These crystal nanophosphors displayed sizes of 18 nm and 22 nm, respectively. The cytotoxic effect of nanoparticles was determined by a cell viability test where the tri-methyl-tetrazolium reagent (MTT) was reduced only by metabolically active cells. Different concentrations of bare nanoparticles were tested in a 96-well plate containing 10, 000 cells per well of a human cervix carcinoma cell line (HeLa). Evaluation of cell viability by this cytotoxic assay showed that in most of the cases cell viability was higher than 60% after incubation with bare nanoparticles. Since our bare nanoparticles were not cytotoxic, these results open a broad field of biomedical applications for phosphorescent materials as cell biolabels and imaging research area.

Abstract

The gravitational collapse in fourth order theories of gravity defined by an arbitrary action of the scalar curvature shows significant deviations with General Relativity. The presence of a new scalar mode produces a higher initial contraction that favors the reduction of the collapsing time. However, depending on the particular model, there are fundamental differences when the modifications to the General Relativity collapse leave the linear regime. These analyses can be used to exclude an important region of the parameter space associated with alternative gravitational models., 4 pages, 2 figures, Contribution to the Proceedings of Spanish Relativity Meeting ERE2011, Madrid 2011

Abstract

Background Up-regulation of S100A7 (Psoriasin), a small calcium-binding protein, is associated with the development of several types of carcinomas, but its function and possibility to serve as a diagnostic or prognostic marker have not been fully defined. In order to prepare antibodies to the protein for immunohistochemical studies we produced the recombinant S100A7 protein in E. coli. mRNA extracted from human tracheal tumor tissue which was amplified by RT-PCR to provide the region coding for the S100A7 gene. The amplified fragment was cloned in the vector pCR2.1-TOPO and sub-cloned in the expression vector pAE. The protein rS100A7 (His-tag) was expressed in E. coli BL21::DE3, purified by affinity chromatography on an Ni-NTA column, recovered in the 2.0 to 3.5 mg/mL range in culture medium, and used to produce a rabbit polyclonal antibody anti-rS100A7 protein. The profile of this polyclonal antibody was evaluated in a tissue microarray. Results The rS100A7 (His-tag) protein was homogeneous by SDS-PAGE and mass spectrometry and was used to produce an anti-recombinant S100A7 (His-tag) rabbit serum (polyclonal antibody anti-rS100A7). The molecular weight of rS100A7 (His-tag) protein determined by linear MALDI-TOF-MS was 12,655.91 Da. The theoretical mass calculated for the nonapeptide attached to the amino terminus is 12,653.26 Da (delta 2.65 Da). Immunostaining with the polyclonal anti-rS100A7 protein generated showed reactivity with little or no background staining in head and neck squamous cell carcinoma cells, detecting S100A7 both in nucleus and cytoplasm. Lower levels of S100A7 were detected in non-neoplastic tissue. Conclusions The polyclonal anti-rS100A7 antibody generated here yielded a good signal-to-noise contrast and should be useful for immunohistochemical detection of S100A7 protein. Its potential use for other epithelial lesions besides human larynx squamous cell carcinoma and non-neoplastic larynx should be explored in future.
