Abstract: The ethical dimension of Operational Research and Decision Aiding, although not a new subject, turns to be a concern, both for the large public and the OR community, because of the wide spread of autonomous artefacts endowed with decision capacity thanks to the use of models, methods and tools developed within our field. The paper addresses the question of whether there exists an "Ethical Operational Research", identifies the ethical questions which are specific to our professional community and suggests research topics which, although independently developed, are relevant for handling such questions.

Abstract: Despite notable scientific and medical advances, broader political, socioeconomic and behavioural factors continue to undercut the response to the COVID-19 pandemic . Here we convened, as part of this Delphi study, a diverse, multidisciplinary panel of 386 academic, health, non-governmental organization, government and other experts in COVID-19 response from 112 countries and territories to recommend specific actions to end this persistent global threat to public health. The panel developed a set of 41 consensus statements and 57 recommendations to governments, health systems, industry and other key stakeholders across six domains: communication; health systems; vaccination; prevention; treatment and care; and inequities. In the wake of nearly three years of fragmented global and national responses, it is instructive to note that three of the highest-ranked recommendations call for the adoption of whole-of-society and whole-of-government approaches , while maintaining proven prevention measures using a vaccines-plus approach that employs a range of public health and financial support measures to complement vaccination. Other recommendations with at least 99% combined agreement advise governments and other stakeholders to improve communication, rebuild public trust and engage communities in the management of pandemic responses. The findings of the study, which have been further endorsed by 184 organizations globally, include points of unanimous agreement, as well as six recommendations with >5% disagreement, that provide health and social policy actions to address inadequacies in the pandemic response and help to bring this public health threat to an end.

Abstract: International audience; This work aims at inferring a set of regular expressions to parse a text file, like a system log. To this end, we propose a novel edit distance taking advantage of the pattern matching background. Edit distances are commonly used for fuzzy search and in bioinformatics, and compare two strings at the character level. By doing so, edit distances do not consider the nature of the data conveyed by the strings. To address this problem, we propose the following contributions. First, we propose to model strings at the pattern level using a dedicated data structure, called pattern automaton. Second, we design a novel edit distance, operating at the pattern level. Third, we derive a clustering algorithm optimized for this distance. Finally, we evaluate our proposal through experimental validation.

Abstract: This word list aims to allow researchers (i) to conduct in-depth lexical investigation when doing fieldwork on languages of Southeast Asia, and (ii) to navigate between languages and dialects, through the use of a unique identifier for each lexical entry. The first version of this word list was created by Ecole Française d'Extrême-Orient (EFEO) for a broad investigation launched in 1938 and interrupted by the war in 1940. A second version of the word list was elaborated at the CNRS laboratory CeDRASEMI (Centre de documentation et de recherche sur l'Asie du Sud-Est et le monde insulindien). This overhaul was supervised by Lucien Bernot, probably between 1960 et 1970; the list was jointly prepared by the Centre de documentation et de recherche sur l'Asie du Sud-Est et le monde insulindien (EPHE-CNRS, Paris) and the Department of South Asia and Oceania of the School of Oriental Studies (University of London) with a view to creating an Ethnolinguistic Atlas of Southeast Asia. Michel Ferlus re-typed the 22-page list to adopt a format suitable for use in the field. As the list remained insufficiently comprehensive for in-depth linguistic fieldwork, Michel Ferlus added further items in the course of his field trips to Vietnam in the 1990s. This list was circulated among Michel Ferlus's colleagues and collaborators. Khmer glosses were added, based on a version of the CeDRASEMI-SOAS list to which Marie Martin had added Khmer glosses. Version 1 of the present document was updated at the International Research Institute MICA in 2013-2014. Chinese glosses were added; English glosses were supplemented; and Vietnamese glosses were revised. The word list is offered online in Open Office format (.ods) and MS-Excel format (.xlsx). In Version 2 (2016), the full set of English translations was checked. In Version 3 (2019), Central Thai, Northern Thai, Lao and Burmese translations were added.In Version 4 (2022), Tibetan translations were added., Cette liste numérotée vise à permettre aux chercheurs de naviguer entre les langues et les dialectes recueillis au fil des ans et sur tous les terrains d'Asie du Sud-Est. La première version de ce lexique a été élaborée par l'Ecole Française d'Extrême-Orient (EFEO) pour une vaste enquête lancée en 1938 et interrompue par la guerre en 1940. L'EFEO en a imprimé une quantité sous la forme de petits fascicules, distribués aux fonctionnaires envoyés en mission par l'administration coloniale (Questionnaire linguistique, Hanoi: Imprimerie d'Extrême-Orient, 1938). Une deuxième version a été élaborée au laboratoire CeDRASEMI du CNRS (Centre de documentation et de recherche sur l'Asie du Sud-Est et le monde insulindien). Lucien Bernot a été la cheville ouvrière de cette amélioration qui a dû se faire entre 1960 et 1970. Cette version était décrite comme un "Questionnaire linguistique préparé conjointement par le Centre de documentation et de recherche sur l'Asie du Sud-Est et le monde insulindien (EPHE-CNRS, Paris) et le Département d'Asie du Sud-Est et d'Océanie de la School of Oriental Studies (University of London) en vue de l'établissement d'un Atlas ethnolinguistique de l'Asie du Sud-Est". Michel Ferlus a re-tapé cette liste pour en faire des cahiers d'enquête commodes à remplir sur le terrain. Comme cette liste restait insuffisante pour une bonne utilisation linguistique, Michel Ferlus l'a augmentée au cours de ses enquêtes au Vietnam dans les années 1990. Cette liste a été enrichie de gloses en khmer, en partie fondées sur la version de la liste CeDRASEMI-SOAS annotée en khmer par Marie Martin. La première version du présent document a été réalisée à l'Institut de recherche international MICA à partir de 2013. Les ajustements principaux ont été les suivants: une nouvelle numérotation a été établie, pour faciliter l'emploi de la liste; des gloses en chinois ont été ajoutées ; les gloses en anglais ont été complétées; et les gloses en vietnamien ont été intégralement révisées. La liste de vocabulaire est mise à libre disposition en ligne au format Open Office (.ods). Dans la version 2 (2016), les gloses anglaises ont été intégralement revues par une équipe coordonnée par Ryan Gehrmann. Dans la version 3 (2019) ont été ajouté le thai central, le thai du Nord, le lao et le birman.Dans la version 4 (2022) a été ajouté le tibétain.

Abstract: International audience; This paper provides an overview of the 2022 COLING Scholarly Document Processing workshop shared task on the detection of automatically generated scientific papers. We frame the detection problem as a binary classification task: given an excerpt of text, label it as either human-written or machine-generated. We shared a dataset containing excerpts from human-written papers as well as artificially generated content and suspicious documents collected by Elsevier publishing and editorial teams. As a test set, the participants were provided with a 5x larger corpus of openly accessible human-written as well as generated papers from the same scientific domains of documents. The shared task saw 180 submissions across 14 participating teams and resulted in two published technical reports. We discuss our findings from the shared task in this overview paper.

Abstract: International audience; Shape-changing User Interfaces (UIs) explore the ability of a UI to change its physical shape to support multiple interaction modalities for users’ input and/or system’s output. An approach currently studied to implement such interfaces at a high resolution is based on mm-sized, round, and self-actuated modules. The problem we tackle in this paper is to find the range of usable sizes of such modules, to better inform the trade-off between usability and technological feasibility. We assessed four sliders in a controlled user study: a standard slider and three sliders made of mock-up rounded modules of ø1 mm, ø2.5 mm, and ø5 mm. Experimental results show that (1) ø5 mm modules significantly impair performance for the pursuit task and subjective perception for both tasks, (2) performance increases when the size of modules decreases, but (3) users reportedly enjoyed the haptic feedback provided by ø1 mm to ø2.5 mm modules. These results provide deeper understanding on the impact of the size of modules on performance and subjective perception to inform current technological development of physical user interfaces made of small robotic modules.

Abstract: Fine prediction of the elastic properties of paper materials can now be obtained using sophisticated fibre scale numerical approaches. However, there is still a need, in particular for low-density papers, for simple and compact analytical models that enable the elastic properties of these papers to be estimated from the knowledge of various structural information about their fibres and their fibrous networks. For that purpose, we pursued the analysis carried out in Marulier et al. (Cellulose 22:1517–1539, 2015. https://doi.org/10.1007/s10570-015-0610-6 ) with low-density papers that were fabricated with planar random and orientated fibrous microstructures and different fibre contents. The fibrous microstructures of these papers were imaged using X-ray synchrotron microtomography. The corresponding 3D images revealed highly connected fibrous networks with small fibre bond areas. Furthermore, the evolutions of their Young’s moduli were non-linear and evolved as power-laws with the fibre content. Current analytical models of the literature do not capture these trends. In light of these experimental data, we developed a fibre network model for the in-plane elasticity of papers in which the main deformation mechanisms of the micromechanical model is the shear of the numerous fibre bonds and their vicinity, whereas the fibre parts far from these zones were considered as rigid bodies. The stiffness tensor of papers was then estimated both numerically using a discrete element code and analytically using additional assumptions. Both approaches nicely fit the experimental trends by adjusting a unique unknown micromechanical parameter, which is the shear stiffness of bonding zones. The estimate of this parameter is relevant in light of several recently reported experimental results.

Abstract: International audience; Speech technology plays an important role in our everyday life. Speech is, among others, used for human-computer interaction, including, for instance, information retrieval and on-line shopping. In the case of an unwritten language, however, speech technology is unfortunately difficult to create, because it cannot be created by the standard combination of pre-trained speech-to-text and text-to-speech subsystems. The research presented in this paper takes the first steps towards speech technology for unwritten languages. Specifically, the aim of this work was 1) to learn speech-to-meaning representations without using text as an intermediate representation, and 2) to test the sufficiency of the learned representations to regenerate speech or translated text, or to retrieve images that depict the meaning of an utterance in an unwritten language. The results suggest that building systems that go directly from speech-to-meaning and from meaning-to-speech, bypassing the need for text, is possible.

Abstract: International audience; The chemical bath deposition of nanowires is of high interest for a wide variety of optoelectronic, piezoelectric, and sensing devices, but a theoretical description of the elongation process is still missing despite its critical importance. By solving Fick’s diffusion equations in combination with thermodynamic computations, we determine the expression of the axial growth rate of nanowires and its temporal dependence under dynamic conditions, namely, in a sealed reactor, where the depletion of chemical reactants occurs. The theoretical model is found to be in very good agreement with a large set of experimental data specifically collected in the case of the chemical bath deposition of ZnOnanowires. In particular, an activation energy of 198 ± 24 kJ/mol is deduced for the elongation process of ZnO nanowires, involving the energy barriers for both the dehydration process of Zn(II) species (i.e., [Zn(H2O)6]2+ ions) and their subsequent direct incorporation onto the c-plane top faces. This shows its high potential to enable in-depth investigation of the physicochemical processes at work in the chemical bath. By using the theoretical model as a predictive approach, a complete growth diagram reporting the evolution of the length of ZnO nanowires vs effective growth time and temperature is also obtained over a broad range of conditions, revealing its additional high potential for applied research and industrial purposes. The present general approach is further compatible with a broad range of chemicals in solution and of semiconducting materials grown by chemical bath deposition.

Abstract: Background: An accurate estimation of the risk of life-threatening (LT) ventricular tachyarrhythmia (VTA) in patients with LMNA mutations is crucial to select candidates for implantable cardioverter-defibrillator implantation. Methods: We included 839 adult patients with LMNA mutations, including 660 from a French nationwide registry in the development sample, and 179 from other countries, referred to 5 tertiary centers for cardiomyopathies, in the validation sample. LTVTA was defined as (1) sudden cardiac death or (2) implantable cardioverter defibrillator–treated or hemodynamically unstable VTA. The prognostic model was derived using the Fine-Gray regression model. The net reclassification was compared with current clinical practice guidelines. The results are presented as means (SD) or medians [interquartile range]. Results: We included 444 patients, 40.6 (14.1) years of age, in the derivation sample and 145 patients, 38.2 (15.0) years, in the validation sample, of whom 86 (19.3%) and 34 (23.4%) experienced LTVTA over 3.6 [1.0–7.2] and 5.1 [2.0–9.3] years of follow-up, respectively. Predictors of LTVTA in the derivation sample were: male sex, nonmissense LMNA mutation, first degree and higher atrioventricular block, nonsustained ventricular tachycardia, and left ventricular ejection fraction (https://lmna-risk-vta.fr). In the derivation sample, C-index (95% CI) of the model was 0.776 (0.711–0.842), and the calibration slope 0.827. In the external validation sample, the C-index was 0.800 (0.642–0.959), and the calibration slope was 1.082 (95% CI, 0.643–1.522). A 5-year estimated risk threshold ≥7% predicted 96.2% of LTVTA and net reclassified 28.8% of patients with LTVTA in comparison with the guidelines-based approach. Conclusions: In comparison with the current standard of care, this risk prediction model for LTVTA in laminopathies significantly facilitated the choice of candidates for implantable cardioverter defibrillators.

Abstract: Quasi phase-pure (>98 wt %) MAX phase solid solution ceramics with the (Zr,Ti)2(Al0.5,Sn0.5)C stoichiometry and variable Zr/Ti ratios were synthesized by both reactive hot pressing and pressureless sintering of ZrH2, TiH2, Al, Sn, and C powder mixtures. The influence of the different processing parameters, such as applied pressure and sintering atmosphere, on phase purity and microstructure of the produced ceramics was investigated. The addition of Sn to the (Zr,Ti)2AlC system was the key to achieve phase purity. Its effect on the crystal structure of a 211-type MAX phase was assessed by calculating the distortions of the octahedral M6C and trigonal M6A prisms due to steric effects. The M6A prismatic distortion values were found to be smaller in Sn-containing double solid solutions than in the (Zr,Ti)2AlC MAX phases. The coefficients of thermal expansion along the ⟨ a⟩ and ⟨ c⟩ directions were measured by means of Rietveld refinement of high-temperature synchrotron X-ray diffraction data of (Zr1- x,Ti x)2(Al0.5,Sn0.5)C MAX phase solid solutions with x = 0, 0.3, 0.7, and 1. The thermal expansion coefficient data of the Ti2(Al0.5,Sn0.5)C solid solution were compared with those of the Ti2AlC and Ti2SnC ternary compounds. The thermal expansion anisotropy increased in the (Zr,Ti)2(Al0.5,Sn0.5)C double solid solution MAX phases as compared to the Zr2(Al0.5,Sn0.5)C and Ti2(Al0.5,Sn0.5)C end-members. ispartof: INORGANIC CHEMISTRY vol:58 issue:10 pages:6669-6683 ispartof: location:United States status: published

Abstract: The research of the best compromise between economic, mechanical and technological imperatives has always been the primary objective of the mechanical engineer. The methods used to achieve these excellence objectives have evolved considerably over the last few years. The author's experience in optimisation began in 1983. At this time, the design stage would come first, then the calculation and finally optimisation afterwards. In practice, and during experience of shape optimisation of mechanical structures, between 1985 and 1990, many extreme cases were encountered. In these cases, the question of optimisation wasn't posed until damage had occurred in service; the author’s industrial partners realized, often too late, that their designing left quite a bit to be desired. They would then call for the author’s help in using optimisation programs to supply them with an improv ed shape. These shapes were reached despite technological limitations being very severe at this stage; so severe, in fact, that engineers were powerless to resolve the problem. Innumerable problems such as this were dealt with. Figure 1 exemplifies this very well. In this case, the very localized optimisation of the rear bearing of a hydraulic hammer is presented (the type of which had been sold in most parts of the world). The bearing in question would break after relatively few cycles of operation. The automatic optimisation of the shape of this product would, simply by a small modification of shape (which would be difficult to predict other than by calculation (increased radius, decreased width), considerably improved the mechanical durability of the bearing: the over-stress being reduced by 50%, the objective being the minimisation of the maximum value of the Von Mises equivalent stress along the mobile contour, whilst taking into account the technological constraints of the industrial partners. Such an approach to designing has become unthinkable these days. The economic competitivity has increased, the design and manufacture delays have

Abstract: Generally speaking, the problem of synthesis of mechanism can be broken down into three sub problems: i) the specification of the problem, ii) the topological synthesis of the mechanism and iii) the dimensional synthesis. This chapter relates in particular to the second sub problem. The chapter could be useful for teachers, researchers, engineers and students who are confronted with the various types of problems concerning the choice of kinematic chains in the initial phase of the topological structural design of an industrial robot. The principal goal of the chapter is to present an overview concerning the chronology of the design of the kinematic chain of an industrial robot. It starts with a review of the methods of synthesis of mechanisms provided by the MMT; then it deals with their representation, validation and concludes with the application of these mechanisms in the initial design phase of industrial robots. The chapter begins with the presentation of a new method for structural synthesis of planar link chains in robotics. It is based on the notion of logical equations. After a brief reminder of the theory of Modular Structural Groups (MSG), and of the connectivity and mobility laws of MMT, various levels of abstraction are studied concerning the complexity of the structure. This permits the synthesis of planar chains with various degrees of complexity expressed by the number of links, joints and the degree of mobility. The logical equations allow the association of MSGs of type A and closed chains of type G. The rules for associations of groups are also presented. The aim is to execute all the possible combinations to join or transform the links in order to obtain as many structures as possible by avoiding those, which are isomorphic. The association of two groups allows the elaboration of different closed chains of upper level. However there are some defect structures, which do not respect the connectivity and mobility laws. Therefore great care has been taken to avoid them. The problem of degenerated structures is central in the synthesis of structures. It concerns especially chains with two and more degrees of mobility. The problem of defect, degeneration and isomorphism is then approached. Finally, a method for description of chains by contours and molecules is proposed. It enables the reduction of the number of the topological structures of the robots concerning the position of the frame and the end-effector of the robot by comparing their respective molecules. This method is then applied for the description of the structures thus obtained (logical equations approach) and for the description of the topology of the principal structure of the industrial robots in the initial phase of their design.

Abstract: Boosted by the simultaneous translation shared task at IWSLT 2020, promising end-to-end online speech translation approaches were recently proposed. They consist in incrementally encoding a speech input (in a source language) and decoding the corresponding text (in a target language) with the best possible trade-off between latency and translation quality. This paper investigates two key aspects of end-to-end simultaneous speech translation: (a) how to encode efficiently the continuous speech flow, and (b) how to segment the speech flow in order to alternate optimally between reading (R: encoding input) and writing (W: decoding output) operations. We extend our previously proposed end-to-end online decoding strategy and show that while replacing BLSTM by ULSTM encoding degrades performance in offline mode, it actually improves both efficiency and performance in online mode. We also measure the impact of different methods to segment the speech signal (using fixed interval boundaries, oracle word boundaries or randomly set boundaries) and show that our best end-to-end online decoding strategy is surprisingly the one that alternates R/W operations on fixed size blocks on our English-German speech translation setup., Accepted for presentation at Interspeech 2021

Abstract: Strict priority policies in a stochastic system with abandonment In the technical note “Stochastic scheduling with abandonment: Necessary and sufficient conditions for the optimality of a strict priority policy,” Chen, Gayon, and Lemaire consider a stochastic scheduling problem in which jobs abandon when their waiting time exceeds their lifetime. Such a problem arises, for example, in call centers or emergency systems. It is known that the optimal policy is a strict priority policy under some sets of conditions. The authors provide the first set of necessary and sufficient conditions for a problem with two types of jobs. They also provide conjectures to guide toward generalizations of the proposed conditions.

Abstract: Estimating the needs of healthcare products and inventory management are still challenging issues in hospitals nowadays. Centers are supposed to cope with tight budgets and patient satisfaction at the same time. Some issues can be tackled in advance, especially regarding the prediction of drug consumption needs. This work delves into the literature in order to highlight existing methods of quantifying and estimating the needs for drugs in health facilities. A second objective is to draw up a list of factors that impact drug consumption in particular, factors that are used in these prediction methods. Following this literature review, it appears that six sustainable methods are being used by practitioners around the world, taking into account certain prerequisites and types of data. Thirty-four factors are identified as well and grouped into three categories. These results should participate in setting up new tools for predicting the need of drugs, to facilitate the upstream dimensioning of new pharmaceutical warehouses and to solve some hospital logistics issues., Comment: CIGI-Qualita : Conf{\'e}rence Internationale G{\'e}nie Industriel QUALITA - Grenoble, May 2021, Grenoble, France

Abstract: Evaluation of information retrieval systems follows the Cranfield paradigm, where the evaluation of several IR systems relies on a common evaluation environment (test collection and evaluation settings). The Cranfield paradigm requires the evaluation environment (EE) to be strictly identical to compare system’s performances. For those cases where such paradigm cannot be used, e.g. when we do not have access to the code of the systems, we consider an evaluation framework that allows for slight changes in the EEs, as the evolution of the document corpus or topics. To do so, we propose to compare systems evaluated on different environments using a reference system, called pivot. In this paper, we present and validate a method to select a pivot, which is used to construct a correct ranking of systems evaluated in different environments. We test our framework on the TREC-COVID test collection, which is composed of five rounds of growing topics, documents and relevance judgments. The results of our experiments show that the pivot strategy can propose a correct ranking of systems evaluated in an evolving test collection.

Abstract: arXiv:1405.3766v1, Unconventional magnetotransport fingerprints in the quantum Hall regime (with applied magnetic fields from one to several tens of Tesla) in chemically functionalized graphene are reported. Upon chemical adsorption of monoatomic oxygen (from $0.5\%$ to few percents), the electron-hole symmetry of Landau levels (LLs) is broken, while a double-peaked conductivity develops at low-energy, resulting from the formation of critical states conveyed by the random network of defects-induced impurity states. Scaling analysis hints towards the existence of an additional zero-energy quantized Hall conductance plateau, which is here not connected to degeneracy lifting of LLs by sublattice symmetry breaking. This singularly contrasts with usual interpretation, and unveils a new playground for tailoring the fundamental characteristics of the quantum Hall effect., J-CC and NL acknowledge financial support from the FRS-FNRS of Belgium.

Abstract: Under the terms of the Creative Commons Attribution License 3.0 (CC-BY)., We report an intriguing transition from the quantum spin Hall phase to the spin Hall effect upon segregation of thallium adatoms adsorbed onto a graphene surface. Landauer-Büttiker and Kubo-Greenwood simulations are used to access both edge and bulk transport physics in disordered thallium-functionalized graphene systems of realistic sizes. Our findings not only quantify the detrimental effects of adatom clustering in the formation of the topological state, but also provide evidence for the emergence of spin accumulation at opposite sample edges driven by spin-dependent scattering induced by thallium islands, which eventually results in a minimum bulk conductivity ~4e2/h, insensitive to localization effects., S.

Abstract: International audience; This paper addresses the issue of matching rigid and articulated shapes through probabilistic point registration. The problem is recast into a missing data framework where unknown correspondences are handled via mixture models. Adopting a maximum likelihood principle, we introduce an innovative EM-like algorithm, namely the Expectation Conditional Maximization for Point Registration (ECMPR) algorithm. The algorithm allows the use of general covariance matrices for the mixture model components and improves over the isotropic covariance case. We analyse in detail the associated consequences in terms of estimation of the registration parameters, and we propose an optimal method for estimating the rotational and translational parameters based on semi-definite positive relaxation. We extend rigid registration to articulated registration. Robustness is ensured by detecting and rejecting outliers through the addition of a uniform component to the Gaussian mixture model at hand. We provide an in-depth analysis of our method and we compare it both theoretically and experimentally with other robust methods for point registration.

Abstract: The efficiency of the superconducting radio frequency cavities composed of Nb required the deposition of thickness-controlled multilayer coatings of superconductor-insulator-superconductor (S-I-S) on the internal surfaces of the cavities. Herein, we report the plasma-enhanced atomic layer deposition of carbon-free NbN (50 µm thick), followed by a thermal treatment, to obtain the superconducting layer in the S-I-S structure. Using (tert-butylimido)-tris(diethylamino)-niobium as the niobium precursor and H2 and NH3 plasma as reactive gasses, the deposition and annealing parameters were optimized by studying their effects on the film properties (crystallinity, density, and composition). We demonstrated that the superconducting critical temperature (Tc) can be improved after thermal annealing up to 13.8 K, a value compatible with the targeted application. In addition to the expected densified layers and increased grain size, we observed a partial transformation of the oxide present in the as-deposited layer into niobium oxynitride, which could indicate the origin of the improvement of the superconducting properties. With low carbon and oxygen impurity concentrations in the films, this study contributes to the understanding of the relationship between the structure, composition, and superconductivity in NbN.

Abstract: 9 pages, 7 figures, CVPR2020 NTIRE2020 Real Image Super-Resolution Challenge; International audience; Benefited from the deep learning, image Super-Resolution has been one of the most developing research fields in computer vision. Depending upon whether using a discriminator or not, a deep convolutional neural network can provide an image with high fidelity or better perceptual quality. Due to the lack of ground truth images in real life, people prefer a photo-realistic image with low fidelity to a blurry image with high fidelity. In this paper, we revisit the classic example based image super-resolution approaches and come up with a novel generative model for perceptual image super-resolution. Given that real images contain various noise and artifacts, we propose a joint image denoising and super-resolution model via Variational AutoEncoder. We come up with a conditional variational autoencoder to encode the reference for dense feature vector which can then be transferred to the decoder for target image denoising. With the aid of the discriminator, an additional overhead of super-resolution subnetwork is attached to super-resolve the denoised image with photo-realistic visual quality. We participated the NTIRE2020 Real Image Super-Resolution Challenge. Experimental results show that by using the proposed approach, we can obtain enlarged images with clean and pleasant features compared to other supervised methods. We also compared our approach with state-of-the-art methods on various datasets to demonstrate the efficiency of our proposed unsupervised super-resolution model.

Abstract: ZnO thin films and nanostructures have received increasing interest in the field of piezoelectricity over the last decade, but their formation mechanisms on silicon when using pulsed-liquid injection metal–organic chemical vapor deposition (PLI-MOCVD) are still open to a large extent. Also, the effects of their morphology, dimensions, polarity, and electrical properties on their piezoelectric properties have not been completely decoupled yet. By only tuning the growth temperature from 400 to 750 °C while fixing the other growth conditions, the morphology transition of ZnO deposits on silicon from stacked thin films to nanowires through columnar thin films is shown. A detailed analysis of their formation mechanisms is further provided. The present transition is associated with strong enhancement of their crystallinity and growth texture along the c-axis together with a massive relaxation of the strain in nanowires. It is also related to a prevailed zinc polarity, for which its uniformity is strongly improved in nanowires. The nucleation of basal-plane stacking faults of I1-type in nanowires is also revealed and related to an emission line at about 3.326 eV in cathodoluminescence spectra, further exhibiting fairly low phonon coupling. Interestingly, the transition is additionally associated with a significant improvement of the piezoelectric amplitude, as determined by piezoresponse force microscopy measurements. The Zn-polar domains exhibit a larger piezoelectric amplitude than the O-polar domains, showing the importance of controlling the polarity in these deposits as a prerequisite to enhance the performances of piezoelectric devices. The present findings demonstrate the high potential in using the PLI-MOCVD system to form ZnO with different morphologies and polarity uniformity on silicon. They further reveal unambiguously the superiority of nanowires over thin films for piezoelectric devices.

Abstract: Scheduling computational jobs with data-sets dependencies is an important challenge of edge computing infrastructures. Although several strategies have been proposed, they have been evaluated through ad-hoc simulator extensions that are, when available, usually not maintained. This is a critical problem because it prevents researchers to-easily-perform fair comparisons between different proposals. In this paper, we propose to address this limitation by presenting a simulation engine dedicated to the evaluation and comparison of scheduling and data movement policies for edge computing use-cases. Built upon the Batsim/SimGrid toolkit, our tool includes a plug-in system that allows researchers to add new models in order to cope with the diversity of edge computing devices. Moreover, it includes an injector that allows the simulator to replay a series of events captured in real infrastructures. We demonstrate the relevance of such a simulation toolkit by studying 2 scheduling strategies with 4 data movement policies on top of a simulated version of the Qarnot Computing platform, a production edge infrastructure based on smart heaters. We chose this use-case as it illustrates the heterogeneity as well as the uncertainties of edge infrastructures. Our ultimate goal is to gather industry and academics around a common simulator so that efforts made by one group can be factorized by others., Ordonnancer efficacement des travaux de calcul avec des dépendances de données est un des plus importants challenges des infrastructures de calcul edge. Bien que plusieurs stratégies ont été proposées, elles ont toutes été évaluées avec des extensions de simulateur ad-hoc qui sont, s’ils sont rendues disponibles, habituellement pas maintenus. C’est un problème critique parce que cela empêche les chercheurs de – facilement – conduire des évaluations équitables entre différentes stratégies proposées. Dans ce rapport de recherche, nous proposons d’adresser cette limitation en présentant un simulateur dédié à l’ évaluation et la comparaison de politiques d’ordonnancement et de mouvement de donnés pour le cas d’usage du calcul edge. Construit au dessus de Batsim/SimGrid, notre outil inclus un sysème de plug-in qui permet aux chercheurs d’ajouter des nouveaux modèles pour faire face à la diversité des appareils de calcul edre. De plus, cet outil inclut un injecteur qui permet au simulateur de rejouer une série d'évènement capturés au sein d’une infrastructure réelle. Nous démontrons la pertinence d’un tel outil de simulation en étudiant 2 stratégies d’ordonnancement avec 4 politiques de mouvements de données sur une version simulée de la plateforme de Qarnot Computing, une infrastructure de production edge basée sur des radiateurs intelligents. Nous avons choisi ce cas d’usage car il illustre l’hétérogénéité et l’incertitude d’une infrastructure de l’edge.Notre but ultime est de rassemble les industriels et les académiques autour d’un simulateur commun afin que les efforts faits par un groupe puissent être factorisés par d’autres.

Abstract: The primary objective of this multicentric dose allocation and dose expansion study was to determine the MTD and the DLTs of the lucitanib (a tyrosine kinase inhibitor of the FGFR/VEGFR/PDFGR pathways)/fulvestrant combination. Postmenopausal women with ER+/HER2− mBC, who have relapsed during or after treatment with fulvestrant, were eligible. The study had a dose allocation part to assess the tolerability of the combination followed by a dose expansion part. Eighteen patients with ER+, mBC were enrolled; median age was 66 years, 50% had a PS: 0 and all had received previous endocrine treatment. The study was prematurely terminated after 18 patients (15 in part 1 and 3 in part 2) based on preclinical experiments that failed to confirm the hypothesis that addition of lucitanib would reverse sensitivity to endocrine treatments. Based on data of global lucitanib development, it was decided to stop the dose allocation at 12.5 mg and to start the dose expansion part at 10 mg/day. The most common grade ≥ 3 toxicities (> 10% of patients) were hypertension (78%) and asthenia (22%). All patients required at ≥ 1 interruption, 13 patients (72%) required ≥ 1 dose reduction. Three patients (72%) withdrew from the study for AEs (at 10 mg). Three patients achieved a confirmed PR (10 mg n = 1; 12.5 mg n = 2). Although the combination is feasible it requires close monitoring of the patients for the management of adverse events. Further investigation is required to better understand the potential role of FGFR inhibition in reversing resistance to endocrine treatment.

Abstract: In this article, we introduce PackingSolver, a new solver for two-dimensional two-and three-staged guillotine Packing Problems. It relies on a simple yet powerful anytime tree search algorithm called Memory Bounded A* (MBA*). This algorithm was first introduced in libralesso2020 for the 2018 ROADEF/EURO challenge glass cutting problem † , for which it had been ranked first during the final phase. In this article, we generalize it for a large variety of Cutting and Packing problems. The resulting program can tackle two-dimensional Bin Packing, Multiple Knapsack, and Strip Packing Problems, with two-or three-staged exact or non-exact guillotine cuts, the orientation of the first cut being imposed or not, and with or without item rotation. Despite its simplicity and genericity, computational experiments show that this approach is competitive compared to the other dedicated algorithms from the literature. It even returns state-of-the-art solutions on several variants. The combination of efficiency, ability to provide good solutions fast, simplicity and versatility makes it particularly suited for industrial applications, which require quickly developing algorithms implementing several business-specific constraints.

Abstract: We consider the recommendations of the World Wide Web Consortium (W3C) about the Resource Description Framework (RDF) and the associated query language SPARQL. We propose a new formal framework based on category theory which provides clear and concise formal definitions of the main basic features of RDF and SPARQL. We propose to define the notions of RDF graphs as well as SPARQL basic graph patterns as objects of some nested categories. This allows one to clarify, in particular, the role of blank nodes. Furthermore, we consider basic SPARQL CONSTRUCT and SELECT queries and formalize their operational semantics following a novel algebraic graph transformation approach called POIM.

Abstract: Understanding the interactions between bedload transport and morpholdynamics in braided streams has important applications in river management and restoration. Direct field measurements addressing this question are however scarce as they are often challenging to perform. Here, we report an extensive two-month field campaign in an Alpine braided reach (La Severaisse river, French Alps) that experienced predictable daily peak discharge (48 events observed) generating significant bedload transport and morphological changes during the melting season. We monitored these processes using a wide range of direct and indirect techniques (bedload sampling, continuous seismic measurements, pebbles tracking, topographic surveys, remote sensing using ground control cameras and drone flights). Doing so, surrogate measurements allowed to extend temporally discrete manual bedload sampling, and to extend spatially local riverbed cross section measurements. These measurements provide unique complementary constraints on the targeted physics, at various spatial and temporal scales which enabled us to draw robust conclusions. Data showed a progressive decrease in bedload transport for a given flow rate along the two months period. Simultaneously, river morphology in the braided sections changed from an incised to a more distributed configuration which led to a decrease of local maxima in dimensionless shear stresses in the braided reach for similar flow conditions. This control of bedload transport by maximum local shear stresses was in line with tracked pebble surveys indicating that coarse bedload particles were mostly transported in the main active channel. At the reach scale, this transport was found to be more efficient in laterally confined sections than in braided ones which has important implications in terms of bedload estimation in alternative confined and braided (unconfined) rivers. Finally, this study highlight the interest to combine a large variety of traditional and innovative measurements techniques to better understand complex sediment transport processes in the field.

Abstract: International audience; This paper deals with the modelling of the mechanical behaviour of coated woven fabric. The proposed model takes into account the individual behaviours of the yarns, the coating and their interactions including the influence of the angle variation between warp and weft yarns. This model is able to describe simultaneously the non-Newtonian viscous behaviour, the time-independent irreversibility, the anisotropy and the cyclic loading behaviour. The model was implemented in the finite element code ABAQUS and enables calculations on structures such as complete sails.

Abstract: Bone fractures are the most common traumatic injuries in humans. The repair of bone fractures is a regenerative process that recapitulates many of the biological events of embryonic skeletal development. Most of the time it leads to successful healing and the recovery of the damaged bone. Unfortunately, about 5-10% of fractures will lead to delayed healing or non-union, more so in the case of co-morbidities such as diabetes. In this article, we review the different strategies to heal bone defects using synthetic bone graft substitutes and biologically active substances or stem cells. Our review is different from previous reviews, which focus on strategies that are still at the early stages of development and use mostly in vitro experiments with cell lines or stem cells. Here, we focus on what is already implemented in the clinics, what is currently in clinical trials, and what has been tested in animal models. Treatment approaches can be classified in three major categories: i) synthetic bone graft substitutes (BGS) whose architecture and surface can be optimized; ii) BGS combined with bioactive molecules such as growth factors, peptides or small molecules targeting bone precursor cells, bone formation and metabolism; iii) cell-based strategies with progenitor cells combined or not with active molecules that can be injected or seeded on BGS for improved delivery. We review the major types of adult stromal cells (bone marrow, adipose and periosteum derived) that have been used and compare their properties. Finally, we discuss the remaining challenges that need to be addressed to significantly improve the healing of bone defects.

Abstract: International audience; Raman spectroscopy is a technique that is now widely used to study all carbon materials and carbon nanostructures and as such is one of the characterization methods that can be used for the analysis of nanodiamonds. In this paper, we focus on detonation nanodiamonds, the contributions and weaknesses of the method for the understanding of their structure and their surface features are reviewed. The choice of the excitation wavelength, from deep UV to more conventional visible wavelengths, and the choice of the experimental conditions are first examined. In particular, experimental conditions are to be adapted to minimize laser-induced effects and to increase the signal to noise ratio of the spectra. Then, the different features observed for the detonation nanodiamonds, in particular the characteristic diamond peak as well as the one usually assigned as a “G” line, are compared to those that are observed from other origins, HPHT or shock wave. The benefit to use different excitation wavelengths to discriminate between samples is underlined. Finally, the effects of annealing under different atmospheres (in reductive atmospheres, e.g. hydrogen; in an oxidative atmosphere (air, oxygen) and in inert atmospheres: argon or in vacuum) were analyzed. Isotopic labelling (deuterated water, 18O) was also considered. The origin of the “G” line is discussed. In specific cases, high resolution TEM images allowed a better understanding of the observed spectra, showing that size dependent reactivity is another parameter to be taken into account during the analysis of the spectra.

Abstract: We report the study of stimuli-responsive ZnII and FeII coordination polymers (MC34+ or MC24+ with M=Fe2+ or Zn2+ ). These soluble metallopolymers were formed spontaneously by reaction of an organic ligand (C34+ or C24+ ) with one molar equivalent of metal ions. The C34+ and C24+ ligands incorporate two chelating terpyridine groups bridged by a redox responsive hinge featuring two viologen units (viologen=N,N'-dialkyl-4,4'-bipyridinium) linked either with propyl (C34+ ) or ethyl (C24+ ) chains. The viologen units in the polymer chains were reduced (1 e- per viologen group) either by bulk electrolysis or by visible-light irradiation carried out in the presence of a photosensitizer. The 1 e- reduction of the viologen units in the MC24+ polymers induced a slight decrease in the viscosity of the solutions due to a modification of the overall charge carried by the metallopolymers. In strong contrast, reduction of coordination polymers involving propyl linkers (MC34+ ) led to a remarkable increase (≈+400 %) in observed viscosity. This reversible effect was attributed to a folding of the polymer chains triggered by π-dimerization of the photo-generated viologen cation radicals.

Abstract: International audience; Since the early 2000s, silicon nanowire field effect transistors are emerging as ultrasensitive biosensors while offering label-free, portable and rapid detection. Nevertheless, their large scale production remains an ongoing challenge due to time consuming, complex and costly technology. In order to bypass these issues, we report here on the first integration of silicon nanowire networks, called nanonet, into long channel field effect transistors using standard microelectronic process. A special attention is paid to the silicidation of the contacts which involved a large number of SiNWs. The electrical characteristics of these FETs constituted by randomly oriented silicon nanowires are also studied. Compatible integration on the back-end of CMOS readout and promising electrical performances open new opportunities for sensing applications.

Abstract: International audience; Carbons were elaborated from purely lignocellulosic precursors (Microfibrillated cellulose and Lignosulfonates blends, simplified as MFC/LS blends) by slow pyrolysis (0.2 °C/min) in a large temperature range (400–1200 °C). They were characterized in terms of morphology (scanning electron microscopy), chemical functionalities (infrared spectroscopy), microstructure (Raman spectroscopy and X-ray diffraction) and physical properties (electrical conductivity and density evolution). MFC/LS carbons could achieve high electrical conductivity of 95 S/cm with regard to their low density, i.e.1.14 g/cm3 after pyrolysis at 1000 °C, compared to other biocarbons. The major aim of this work was to understand the electrical conductivity development in MFC/LS-derived biocarbons during the pyrolysis. A descriptive model, based on the progressive conversion of the biomass into conductive engineering carbons and composed of 3 distinct phases, was thus established to illustrate the electrical conductivity development phenomenon.

Two experiments were conducted. The first one involved a geosynthetic clay liner, a nonwoven needle-punched geotextile and a high-density polyethylene geomembrane. For the second experiment, a 50 kN/m polyvinyl alcohol geogrid was embedded within the sand layer below the geosynthetic clay liner to provide reinforcement above the cavity. An overburden pressure varying from 10 to 100 kPa was applied to the top of the GLS. Strain gauges were used to measure the strain within the geogrid and the geomembrane. The results proved that the 50 kN/m geogrid reinforcement beneath the geomembrane reduced the maximum strain within the geomembrane, compared to the case where the geomembrane was unreinforced, by 25% on average. The results showed that the overall strain within the geomembrane was 31% to 42% less than that of the geogrid above the cavity. Finally, the results showed that the spatial distribution of the strain within the geomembrane and that of the geogrid differed because of a conical shape of the collapsed zone.

Abstract: The emission of circularly polarized light from a single quantum dot relies on the injection of carriers with well-defined spin polarization. Here we demonstrate single dot electroluminescence (EL) with a circular polarization degree up to 35% at zero applied magnetic field. The injection of spin polarized electrons is achieved by combining ultrathin CoFeB electrodes on top of a spin-LED device with p-type InGaAs quantum dots in the active region. We measure an Overhauser shift of several $\mu$eV at zero magnetic field for the positively charged exciton (trion X$^+$) EL emission, which changes sign as we reverse the injected electron spin orientation. This is a signature of dynamic polarization of the nuclear spins in the quantum dot induced by the hyperfine interaction with the electrically injected electron spin. This study paves the way for electrical control of nuclear spin polarization in a single quantum dot without any external magnetic field., Comment: initial version, final version to appear in ACS Nano Letters

Abstract: International audience; Flax fibre mats are promising and versatile biosourced reinforcements that can be used in composite parts obtained using various processing routes. To optimise their impregnation and the end-use properties of composites, it is crucial to better understand the process-induced evolution of their microstructure and their permeability. In this study, flax fibre mats were subjected to in situ X-ray microtomography compression experiments. The resulting 3D images enabled the evolution of several key descriptors of their microstructure under compression to be determined, and the evolution of their permeability to be quantified by direct fibre scale CFD simulations. The microstructural data were also used as input parameters of a modified directional Kozeny-Carman model, accounting for the anisotropy and heterogeneity of mats. Only one unknown directional parameter was identified by inverse method from permeability calculations performed on numerically generated 3D realistic fibre networks. The predictions of the proposed model were consistent with numerical simulations.

Abstract: International audience; This paper describes research done on a new testing device including its laboratory test procedure; namely, a laboratory punching test for cementitious backfill materials that evaluates their excavatability with a pick. Three-dimensional and two-dimensional numerical studies using a finite element method were carried out according to calibrated parameters of the material obtained by triaxial tests. This made it possible to study the behavior of the backfill material under action induced by a tool (a pick) as well as to optimize the geometry of the punching test specimen. This paper provides detailed information and results for the experimental study of this laboratory test. Attention was particularly focused on energy relating to displacement as well as types of ruptures. The behavior of these types of materials was found to be greatly influenced by gravel in the material. Repeatability of the test was also studied. Finally, a method for this punching test of backfill materials is also provided.

Abstract: International audience; Moesin, a protein of the ezrin, radixin, and moesin family, which links the plasma membrane to the cytoskeleton, is involved in multiple physiological and pathological processes, including viral budding and infection. Its interaction with the plasma membrane occurs via a key phosphoinositide, the phosphatidyl(4,5)inositol-bisphosphate (PIP2), and phosphorylation of residue T558, which has been shown to contribute, in cellulo, to a conformationally open protein. We study the impact of a double phosphomimetic mutation of moesin (T235D, T558D), which mimics the phosphorylation state of the protein, on protein/PIP2/microtubule interactions. Analytical ultracentrifugation in the micromolar range showed moesin in the monomer and dimer forms, with wild-type (WT) moesin containing a slightly larger fraction (∼30%) of dimers than DD moesin (10-20%). Only DD moesin was responsive to PIP2 in its micellar form. Quantitative cosedimentation assays using large unilamellar vesicles and quartz crystal microbalance on supported lipid bilayers containing PIP2 reveal a specific cooperative interaction for DD moesin with an ability to bind two PIP2 molecules simultaneously, whereas WT moesin was able to bind only one. In addition, DD moesin could subsequently interact with microtubules, whereas WT moesin was unable to do so. Altogether, our results point to an important role of these two phosphorylation sites in the opening of moesin: since DD moesin is intrinsically in a more open conformation than WT moesin, this intermolecular interaction is reinforced by its binding to PIP2. We also highlight important differences between moesin and ezrin, which appear to be finely regulated and to exhibit distinct molecular behaviors.

Abstract: Statistical downscaling models (SDMs) are often used to produce local weather scenarios from large-scale atmospheric information. SDMs include transfer functions which are based on a statistical link identified from observations between local weather and a set of large-scale predictors. As physical processes driving surface weather vary in time, the most relevant predictors and the regression link are likely to vary in time too. This is well known for precipitation for instance and the link is thus often estimated after some seasonal stratification of the data. In this study, we present a two-stage analog/regression model where the regression link is estimated from atmospheric analogs of the current prediction day. Atmospheric analogs are identified from fields of geopotential heights at 1000 and 500 hPa. For the regression stage, two generalized linear models are further used to model the probability of precipitation occurrence and the distribution of non-zero precipitation amounts, respectively. The two-stage model is evaluated for the probabilistic prediction of small-scale precipitation over France. It noticeably improves the skill of the prediction for both precipitation occurrence and amount. As the analog days vary from one prediction day to another, the atmospheric predictors selected in the regression stage and the value of the corresponding regression coefficients can vary from one prediction day to another. The model allows thus for a day-to-day adaptive and tailored downscaling. It can also reveal specific predictors for peculiar and non-frequent weather configurations.

Abstract: International audience; Embedded devices of the Internet of Things form the so-called low-power and lossy networks. In these networks, nodes are constrained in terms of energy, memory and processing. Links are lossy and exhibit a transient behavior. From the point of view of energy expenditure, governing control overhead emission is crucial and is the role of the Trickle algorithm. We address Trickle's fairness problem to evenly distribute the transmission load across the network, while keeping the total message count low. First, we analytically analyze two underlying causes of unfairness in Trickle networks: desynchronization among nodes and non-uniform topologies. Based on our analysis, we propose a first algorithm whose performance and parameters we study in an emulated environment. From this feedback, we design a second algorithm TrickleD that adapts the redundancy parameter to achieve high fairness while keeping the transmission load low. We validate TrickleD in real-life conditions using a large scale experimental testbed. TrickleD requires minimal changes to Trickle, zero user input, emits 17.7% less messages than state-of-the-art and 37.2% less messages than state-of-practice, while guaranteeing high fairness across the network.

Abstract: International audience; Despite of a growing use of the poly-L-lysine dendrigrafts in biomedical applications , a deeper understanding of the molecular level properties of these macromolecules is missing. Herein, we report a simple methodology for the construction of three dimensional structures of poly-L-lysine dendrigrafts, and the subsequent investigation of their structural features using microsecond molecular dynamics simulations. Thismethodology relies on the encoding of the polymers– experimental characterizations (i.e.composition, degrees of polymerization, branching ratios, charges) into alphanumeric strings that are readable by the Amber simulation package. Such an original approach opens avenues toward thein silico exploration of dendrigrafts and hyper-branched polymers

Abstract: International audience; Flexible barriers are widely used as protection structures against natural hazards in mountainous regions, in particular for containing granular materials such as debris flows, snow avalanches and rock slides. This article presents a discrete element method-based model developed in the aim of investigating the response of flexible barriers in such contexts. It allows for accounting for the peculiar mechanical and geometrical characteristics of both the granular flow and the barrier in a same framework, and with limited assumptions. The model, developed with YADE software, is described in detail, as well as its calibration. In particular, cables are modeled as continuous bodies. Besides, it naturally considers the sliding of rings along supporting cables. The model is then applied for a generic flexible barrier to demonstrate its capacities in accounting for the behavior of different components. A detailed analysis of the forces in the different components showed that energy dissipators (ED) had limited influence on total force applied to the barrier and retaining capacity, but greatly influenced the load transmission within the barrier and the force in anchors. A sensitivity analysis showed that the barrier's response significantly changes according to the choice of ED activation force and incoming flow conditions.
