description: L’étude suivante, présente sous la base d’une série d’essais réalisés sur des éprouvettes d’essences tempérée (sapin blanc du massif central ou Picea alba Mils) et tropicale (okoumé du Gabon ou Aucoumea Klaineana Pierre…), une base de données de leurs différentes propriétés physiques et mécaniques. Les essais sont réalisés en intérieur à température ambiante, sur des éprouvettes dimensionnées selon la norme française [AFN 06]. Ces éprouvettes, dont les propriétés physiques sont préalablement déterminées, sont chargées en flexion statique 4-points sur une presse électrostatique. Puis grâce à des méthodes de calculs normalisées, une détermination des principaux paramètres mécaniques de ces espèces est effectuée. Pour des densités proches, les résultats des différentes analyses comparatives montrent qu’il n’y a pas de différences significatives entre les paramètres mis en valeur, dans cette étude, pour ces différentes espèces malgré la différence de leurs zones de croissances.

description: Fast Radio Bursts (FRBs) are highly energetic radio transients with millisecond duration, whose physical origin is still unknown. Many models consider magnetars as possible FRB sources, supported by the observational association of FRBs with the galactic magnetar SGR 1935+2154. Magnetars are also thought to be the source of the power of a fraction of Gamma Ray Bursts (GRBs), opening the possibility that the two extreme phenomena have a common progenitor. In this work we put constrains to this hypothesis searching for possible associations between GRBs and FRBs with currently available catalogs, and estimating if the lack of coincident detection can rule out their association. We cross-matched all the Swift GRBs detected so far with all the well-localised FRBs reported in the FRBSTATS catalog, and we looked for FRB-GRB associations considering both spatial and temporal constraints. We also simulated a synthetic population of FRBs associated with Swift GRBs to estimate how likely it is to have a joint detection with current and future radio facilities. We recover two, low significant, possible associations already reported in literature from the catalogs' matches: GRB 110715A/FRB 20171209A and GRB 060502B/FRB 20190309A. However, our study shows that the absence of any unambiguous association so far between Swift GRBs and FRBs cannot exclude that the two populations are connected, given the characteristics of current GRB and FRB detectors. Currently available observational data are not sufficient to clearly exclude/confirm whether GRBs and FRBs are physically associated. In the next decade, with new generations of GRB and FRB detectors there will be a higher probability to detect joint GRB-FRB events, if any: future observations will therefore be key to put more stringent constraints on the hypothesis that FRBs and GRBs have common progenitors.

description: Let $W$ denote $d$-dimensional Brownian motion. We find an explicit formula for the essential supremum of Hausdorff dimension of $W(E)\cap F$, where $E\subset(0,\infty)$ and $F\subset \mathbf {R}^d$ are arbitrary nonrandom compact sets. Our formula is related intimately to the thermal capacity of Watson [Proc. Lond. Math. Soc. (3) 37 (1978) 342-362]. We prove also that when $d\ge2$, our formula can be described in terms of the Hausdorff dimension of $E\times F$, where $E\times F$ is viewed as a subspace of space time.

One-loop N = 4 super Yang-Mills scattering amplitudes in d dimensions, relation to open strings and polygonal Wilson loops

description: In this review we discuss some recent developments related to one-loop N = 4 super Yang-Mills scattering amplitudes calculated to all orders in epsilon. It is often the case that one-loop gauge theory computations are carried out to order epsilon^0, since higher order in epsilon contributions vanish in the limit as epsilon goes to zero. We will show, however, that the higher order contributions are actually quite useful. In the context of maximally supersymmetric Yang-Mills, we consider two examples in detail to illustrate our point. First we concentrate on computations with gluonic external states and argue that N = 4 supersymmetry implies a simple relation between all-orders-in-epsilon one-loop N = 4 super Yang-Mills amplitudes and the first and second stringy corrections to analogous tree-level superstring amplitudes. For our second example we will derive a new result for the all-orders-in-epsilon one-loop superamplitude for planar six-particle NMHV scattering, an object which allows one to easily obtain six-point NMHV amplitudes with arbitrary external states. We will then discuss the relevance of this computation to the evaluation of the ratio of the planar two-loop six-point NMHV superamplitude to the planar two-loop six-point MHV superamplitude, a quantity which is expected to have remarkable properties and has been the subject of much recent investigation.

name: Irene Bernardeschi

Publisher: name: Zenodo
Year: 2020

description: In this Deliverable the prototypes of PEG-fibrinogen-based hydrogel formulations developed by REGENTIS and their main features are described.
In section 2, the key specifications identified for the hydrogels are reported, also with a description of the three material types developed, as well as of the methods and techniques used to optimize the hydrogel formulations based on the required specifications.
Then, in section 2.1, the results of preliminary biological tests performed to assess the viability of human adipose tissue-derived stem cells (ASCs) after cell encapsulation within PEG-fibrinogen printed hydrogels are reported. These tests also served to evaluate the right amount of photoinitiator, UV intensity and exposure time to be employed to have a material respecting the specifications.
After this preliminary analysis, an optimization process for PEG-based hydrogel formulations is described in the same section. This implied to vary: i) the total amount of Pluronic and ii) the ratio of non-cross-linkable and UVA-cross-linkable Pluronic. Material characterization in terms of mechanical and rheological properties, the diffusivity of proteins in the material and cell viability of human chondrocytes are also reported in section 2.1 for the different formulations. Results indicate that the formulations containing a lower amount of cross-linkable Pluronic show a higher swelling, a lower shear modulus (G') and a smaller Young modulus (E), corresponding to a few kPa.
Results on protein diffusivity, obtained by testing some selected formulations, are reported in section 2.2 and suggest that the decreased amount of Pluronic increases the “permeability” of the material to nutrients available in the medium surrounding the hydrogels. However, even the formulation showing the highest diffusivity between the ones tested, does not guarantee a sufficient level of human chondrocytes cell viability, highlighting a possible relevant role played by material chemistry, with the tested cell type.
In conclusion, the PEG-fibrinogen-based hydrogels do not result in good candidates usable as the matrix of the nanocomposite materials envisaged in ADMAIORA.

description: Identification of novel genetic causes for rare or genetically heterogeneous diseases relies on fast and straightforward accessibility of related OMICs studies. Although there is already a multitude of disease-specific genomic web databases, many diseases are still not or not sufficiently represented. In order to support researchers in the domains of medicine and biology to implement disease-specific web applications in their fields, the open source template myGeneAtlas is currently under development. It is based on a recently published web application for the field of male infertility, the Male Fertility Gene Atlas [1]. The template, provides all main functionalities of gene atlas web applications: Registered users can upload data of relevant OMICs studies, i.e. meta information, annotations regarding phenotypes, processed cells and tissues as well as images and tables. Data, most importantly images and tables, can then easily be viewed on the website and automatically be searched for mentioning of gene names and other annotations. MyGeneAtlas is java-based and employs the frameworks Hibernate and Spring Boot on the server side and Bootstrap on the client side for a modern and responsive web design. Wherever possible, appropriate ontologies are integrated.

description: Fast X-ray transients (FXTs) are X-ray flares lasting minutes to hours. Multi-wavelength counterparts to these FXTs have been proven hard to find. As a result distance measurements are through indirect methods such as host galaxy identification. The three main models proposed for FXTs; supernova shock breakout emission (SN SBO), binary neutron star (BNS) mergers and tidal dirsuption events (TDEs) of an intermediate mass black hole (IMBH) disrupting a white dwarf (WD), have a different associated L$_{X, peak}$. Therefore obtaining the distance to FXTs will be a powerful probe to investigate the nature of these FXTs. We use VLT/MUSE observations of a sample of FXTs to report the redshift of between 13 and 22 galaxies per FXT and use these redshifts to calculate the distance, L$_{X, peak}$ and the projected offsets. We find L$_{X, peak}>10^{44}$ erg s$^{-1}$ if we assume any of the sources with a redshift measurement is the true host galaxy of the corresponding FXT. For XRT 100831 we find a very faint galaxy within the 1$σ$ uncertainty region with a chance alignment probability of 0.04. For XRT 060207 we find a candidate host galaxy at z = 0.939 with a low chance alignment probability. However, we also report the detection of a late-type star within the 3$σ$ uncertainty region with a similar chance alignment probability. For the remaining FXTs we find no sources within their 3$σ$ uncertainty regions. We rule out a SN SBO nature for all FXTs based on L$_{X, peak}$ and the projected offsets. For XRT 100831 we conclude the detected galaxy within the 1$σ$ uncertainty position is likely to be the host galaxy of this FXT. From the available information, we are not able to determine if XRT 060207 originated from the galaxy found within 1$σ$ of the FXT position or was due to a flare from the late-type star detected within the 3$σ$ uncertainty region.

description: The noise exposure levels of workers wearing hearing protective devices (HPDs) depend on ambient noise and the protective effect of hearing protectors. This cross-sectional study aimed to adjust for cumulative noise exposure (CNE) based on the effective protection of hearing protection devices and explore the dose–response relationship between noise-induced hearing loss (NIHL) and adjusted cumulative noise exposure. A questionnaire was used to acquire the basic characteristics and occupational information of noise-exposed workers. Individual noise dosimetry, individual fitting tests, and pure-tone audiometric tests were performed to assess workers’ noise exposure levels, HPDs’ sound attenuation, and hearing status. A total of 714 workers participated in this study. Four hundred seventy-three participants wore foam earplugs and 241 wore pre-molded earplugs. The median Personal Attenuation Rating (PAR) was 13.0 dB. The median PAR′ (the PAR after combining the earplugs usage time) was 8.0 dB. Thirty-one percent of the workers wore earplugs properly during noise exposure and they tended to possess a greater PAR. The median LAeq,8h was 94.1 dB (A) and the median unadjusted cumulative noise exposure was 102.3 dB (A)· year. The PAR′-adjusted CNE (CNEP) was 91.3 dB (A)·year. A total of 161 workers (22.5%) with hearing loss were identified. There was an obvious trend between the prevalence of NIHL and CNEP (χtrend2 = 31.9, p < 0.01). The Wald values of the CNE and CNEP logistic regression models were 4.0 and 14.1, respectively. Furthermore, the curve slope of the CNEP was steeper than that of the unadjusted CNE. The CNEP can represent the noise exposure level among workers wearing hearing protectors more accurately and has an apparent dose–response relationship with the prevalence of NIHL. For workers utilizing hearing protection devices, wearing them properly and consistently in the workplace is recommended. Assessing noise exposure based on the protective effects of hearing protectors is also essential. Additional studies are needed to quantify the impact of behaviors associated with the improper use of hearing protection.

description: A quantum system (with Hilbert space $\mathscr{H}_1$) entangled with its environment (with Hilbert space $\mathscr{H}_2$) is usually not attributed a wave function but only a reduced density matrix $ρ_1$. Nevertheless, there is a precise way of attributing to it a random wave function $ψ_1$, called its conditional wave function, whose probability distribution $μ_1$ depends on the entangled wave function $ψ\in\mathscr{H}_1\otimes\mathscr{H}_2$ in the Hilbert space of system and environment together. It also depends on a choice of orthonormal basis of $\mathscr{H}_2$ but in relevant cases, as we show, not very much. We prove several universality (or typicality) results about $μ_1$, e.g., that if the environment is sufficiently large then for every orthonormal basis of $\mathscr{H}_2$, most entangled states $ψ$ with given reduced density matrix $ρ_1$ are such that $μ_1$ is close to one of the so-called GAP (Gaussian adjusted projected) measures, $GAP(ρ_1)$. We also show that, for most entangled states $ψ$ from a microcanonical subspace (spanned by the eigenvectors of the Hamiltonian with energies in a narrow interval $[E,E+δE]$) and most orthonormal bases of $\mathscr{H}_2$, $μ_1$ is close to $GAP(\mathrm{tr}_2 ρ_{mc})$ with $ρ_{mc}$ the normalized projection to the microcanonical subspace. In particular, if the coupling between the system and the environment is weak, then $μ_1$ is close to $GAP(ρ_β)$ with $ρ_β$ the canonical density matrix on $\mathscr{H}_1$ at inverse temperature $β=β(E)$. This provides the mathematical justification of our claim in [J. Statist. Phys. 125:1193 (2006), http://arxiv.org/abs/quant-ph/0309021] that $GAP$ measures describe the thermal equilibrium distribution of the wave function.

description: In this Deliverable, the main features of the Pluronic-fibrinogen based formulations developed by REGENTIS are described.
In particular, in the Introduction of section 2 the main specifications identified for the hydrogels are reported, also with a description of the three types of materials developed and the methods and techniques used to optimize the basal hydrogel formulations, based on the specifications. In section 2.1, the Pluronic-fibrinogen based hydrogel formulation optimization is described, together with material characterization results, in terms of mechanical and rheological properties. Diffusivity of proteins in the material and cell viability on human chondrocytes are reported in section 2.2.
The material tended to shrink when incubated at 37°C in a saline solution after being cross-linked with UV light. No marked gradients of fluorescent proteins were observed, indicating a good diffusivity of nutrients into the material. However, such a material formulation did not guarantee a high level of cell viability, probably due to material chemistry. For this reason, the Pluronic-fibrinogen based hydrogel did not result in a good candidate for the project purposes.

An experimental investigation and multicriteria decision making into flax and carbon fibres reinforced biopolymers for outdoor structural applications
Creators: name: Margoto, Olivia Helena
Publisher: name: University of British Columbia
Year: 2022

description: Growing concerns on climate change have been leading many manufacturing sectors to be more environmentally conscious, valuing renewable materials, and reusing resources and waste. Aligned with the same trend, biobased polymer composites and natural fibre reinforcements are being considered widely as an alternative to non-renewable composites, while targeting similar properties. This study primarily aims to investigate the weathering resistance of a set of natural fibre reinforced biobased polymer composites towards expanding their outdoor structural applications. For this, three subsequent tasks were carried out. In task 1, a flax fibre fabric and its monofilaments’ physical, mechanical, and thermal properties were characterized. The flax fibre fabric characterized was then used as a composite reinforcement in tasks 2 and 3. Next, task 2 investigated the mechanical and thermal performance of a flax fibre reinforced green high-density polyethylene, made through compression moulding. Task 3 then focused primarily on the effect of natural and accelerated weathering on the mechanical (including tensile, impact, damping, hardness) and physical (density, roughness) properties of flax fibre (FF) and carbon fibre (CF) reinforced thermoset bioresins. For the latter study, the biocomposite samples were fabricated using two different manufacturing techniques. Flax fibre reinforced biobased epoxy (Bioepoxy/35%FF) was made through vacuum infusion. Flax and carbon fibre pre-impregnated with a Polyfurfuryl Alcohol (PFA) resin were used, on the other hand, to fabricate PFA/60%FF, PFA/45%FF-15%CF and PFA/60%CF through vacuum bagging. Bioepoxy/35%FF and PFA/60%FF showed similar density, tensile, and impact properties and performed at least 150% better in damping than CF composites. Notably, by replacing only 15 % of flax with carbon fibre, PFA/45%FF-15%CF had an increase of 130 % in tensile strength and 90 % in modulus. Natural weathering exposures for 30 and 90 days did not statistically affect the tensile and hardness properties of the tested thermoset biocomposites compared to the respective controls. Finally, a multicriteria decision-making method, namely PROMETHEE II, was used to rank the biocomposite options characterized in task 3. PFA/60%CF was ranked first, followed by PFA/45%FF-15%CF, PFA/60%FF and lastly, Bioepoxy/35%FF. This shows that a hybrid biocomposite solution can be an excellent option to fulfill both mechanical performance and weathering concerns for outdoor structural applications.

description: Diese kumulative Habilitation behandelt die wissenschaftliche Analyse der kontrastmittelverstärkten Magnetresonanztomographie in der Diagnostik von Krankheitsbildern der muskuloskelettalen Radiologie. Die MRT-basierte Bildgebung hat in der Diagnostik sowohl gutartiger als auch maligner muskuloskelettaler Erkrankungen einen hohen Stellenwert. 
Teilprojekt 1 beschäftigte sich mit der MRT-basierten Diagnostik der Frozen Shoulder, auch genannt adhäsive Kapsulitis. Die Frozen Shoulder ist eine häufige Erkrankung in der Bevölkerung mittleren Alters, bei der die Patientinnen und Patienten unter einer schmerzhaft eingeschränkten Bewegungsfähigkeit der Schulter leiden, wobei primär konservative Therapieverfahren eingesetzt werden. Eine korrekte und frühzeitige klinische und radiologische Diagnose ist dabei wesentlich für eine adäquate Behandlung. Ziel des Projektes war es, die Relevanz kontrastmittelverstärkter Sequenzen für die MRT-basierte Diagnosestellung zu eruieren.
Teilprojekt 2 behandelte den Einfluss neuartiger, dynamisch-kontrastverstärkter MRT-Sequenzen sowie einzelner MRT-Bildgebungsparameter auf die diagnostische Aussagekraft der MRT in der Erkennung von Rezidiven von Weichteilsarkomen nach multimodaler Therapie. Die MRT ist derzeit eine wichtige Säule in der Nachsorge dieser Patientengruppe und wird in den ersten drei Jahren nach Resektion routinemäßig alle 3-4 Monate durchgeführt. Zentrale Fragestellungen waren die mögliche Verbesserung der diagnostischen Aussagekraft der MRT durch dynamisch-kontrastverstärkte Sequenzen sowie die Relevanz von MRT-Voruntersuchungen und einzelner MR-morphologischer Bildparameter.
In Teilprojekt 3 wurden Assoziationen des Ödems des Quadrizeps-Fettkörpers mit Alterationen der Sehne des M. quadriceps femoris untersucht. Ein Ödem des Quadrizeps-Fettkörpers wird in der Literatur als Ursache für vorderen Knieschmerz betrachtet, seine Ätiologie bleibt jedoch umstritten. Ziel dieser Studie war es, einen möglichen Zusammenhang zwischen dem Ödem des Quadrizeps-Fettkörpers, Veränderungen der angrenzenden Quadrizepssehne sowie Strukturen im vorderen Knie zu analysieren.

description: Background: The Delphi method is a demonstrated way to gather structured expert opinions to forecast, plan, and prioritize around a given topic. It builds consensus through iterative rounds. Aims: The goal of this study was to build consensus-based predictions for the year 2022 about: future trends in surgeon continuing medical education (CME); the role of technology in learning for surgeons of different experience levels (trainee/resident, practicing, expert); and CME funding models. Methods: A three round e-Delphi method was employed for this study. Panelist identities were anonymized, and controlled feedback and consensus rules were employed. Fifteen international expert panelists’ input was collected via electronically distributed, open-ended questionnaire (Round 1) and 5-point Likert scale ranking surveys (Rounds 2 and 3), in a series of nine questions (Round 1) and 26 and 25 summary statements (Rounds 2 and 3, respectively). Summary statements were collated via key words and ideas collected from panelist’s input. Mean, median, standard deviation, and 95% confidence intervals were calculated. Results: Response rate was 100% for each round. Consensus in Round 2 was 61% and 88% in Round 3. Seven key finding statements with supporting background information was the result. Discussion: Reliable, affordable internet access was identified as a likely barrier to education for certain regions, even in 5 years’ time. The use of similar educational resources were identified for all levels of surgeon, what varied was the reliance on a particular resource by each level of surgeon. Conclusion: Institutes of employment were predicted to have ended CME funding for expert surgeons by 2022. Industry sponsored CME was predicted to have a continued role for trainee/residents and practicing surgeons.

description: In this paper we analyze the behavior of solutions of the Neumann problem posed in a thin domain of the type $R^ε= \{(x_1,x_2) \in \R^2 \; | \; x_1 \in (0,1), \, - \, ε\, b(x_1) < x_2 < ε\, G(x_1, x_1/ε^α) \}$ with $α>1$ and $ε> 0$, defined by smooth functions $b(x)$ and $G(x,y)$, where the function $G$ is supposed to be $l(x)$-periodic in the second variable $y$. The condition $α> 1$ implies that the upper boundary of this thin domain presents a very high oscillatory behavior. Indeed, we have that the order of its oscillations is larger than the order of the amplitude and height of $R^ε$ given by the small parameter $ε$. We also consider more general and complicated geometries for thin domains which are not given as the graph of certain smooth functions, but rather more comb-like domains.

description: Background: Clinical reasoning is a key ability essential for practising health professionals. However, little is known about the current global adoption of clinical reasoning teaching and assessment. Purpose: We aimed to provide insights into how clinical reasoning is deliberately taught and assessed in curricula worldwide and to identify needs and perceived barriers for teaching clinical reasoning to students and educators. Methods: A questionnaire was devised by an international expert group and distributed in a large international medical education community. Data were collected in 2018 and analysed using descriptive statistics. We identified themes in free-text responses using content analysis. Results: Three hundred and thirteen responses from 76 countries were collected. Most respondents were from Europe (34%). While the presence of a longitudinal clinical reasoning curriculum was only reported by 28%, 85% stated that such a curriculum was needed. The lack of awareness of the need to explicitly teach clinical reasoning was the most commonly identified barrier. For assessment, the greatest need identified was for more workplace-based assessment. Conclusions: Global respondents indicate the need to implement explicit longitudinal clinical reasoning curricula. Our findings suggest that efforts should be put into improving faculty development, including evidence-based materials on how to teach and assess clinical reasoning.

description: La ligne de chemin de fer qui traverse le Gabon du Nord-Ouest vers le Sud-Est, constitue le moyen de transport stratégique vis-à-vis du développement économique du pays. Or, une partie de l’infrastructure ferroviaire est construite sur des sols fins à priori inaptes à recevoir une plateforme ferroviaire. Sur cette partie de la ligne, sont répertoriés des problèmes d’instabilité récurrents et dont l’ampleur devient encore plus importante avec l’augmentation de la charge à l’essieu des wagons des trains minéraliers à plus de 25 tonnes. Selon [LI 95], les mécanismes de défaillances survenant sur les plateformes ferroviaires en matériau fins argileux sont dus à la combinaison de trois facteurs : la nature argileuse du sol de plateforme, la présence d’eau et l’effet du chargement cyclique des essieux des différents véhicules ferroviaires. Dans cet article, nous nous intéressons à l’étude du comportement des sols argileux des plateformes ferroviaires dans le contexte d’augmentation de la charge à l’essieu, en prenant en compte la variation de leur état hydrique.

In addition, we require each star to be observed in at least 6 sectors in each North/South Cycle: 1,950 low mass stars meet these criteria. Strong evidence was seen in 245 stars for a very stable photometric variation which we assume to be a signature of the stars rotation period. We did a similar study for Solar-like stars and found that 194 out of 1432 stars had a very stable modulation. We then searched for evidence of a variation in the rotational amplitude. We found 26 low mass stars showed evidence of variability in their photometric amplitude and only one Solar-like star. Some show a monotonic trend over 3--4 yrs whilst other show shorter term variations. We determine the predicted cycle durations of these stars using the relationship found by Irving (2023} using an estimate of the stars Rossby number. Finally we find a marginally statistically significant correlation between the range in the rotational amplitude modulation and the rotation period.

description: In this expository paper we present an overview of various graphical categorifications of the Heisenberg algebra and its Fock space representation. We begin with a discussion of "weak" categorifications via modules for Hecke algebras and "geometrizations" in terms of the cohomology of the Hilbert scheme. We then turn our attention to more recent "strong" categorifications involving planar diagrammatics and derived categories of coherent sheaves on Hilbert schemes.

description: Purpose: Gamification or learning using game elements is a process that seeks to capture students’ interest. One of the most popular games in recent years is the Escape Room, but the study of its use in education and with health professionals is still limited. The aim of this study was to find out the perceptions and experiences of final year nursing students in an Objective Structured Clinical Examination (OSCE) by means of an Escape Room. Methods: In January 2019, 9 focus groups (FG) were held, with a total of 95 final year nursing students. We applied a qualitative content analysis approach and ATLAS.ti version 8 was used for data analysis. Results: The data revealed 3 main themes and 8 sub-themes. The three main themes, which were mapped to the conceptual framework, were student learning outcomes, emotional impact on students and conclusions on the serious games experience. Both the main themes and the sub-themes were illustrated using representative quotes from the participants. Conclusions: These results can help to apply these methodologies, such as the Escape Room, alongside other pre-existing ones, complementing the way in which students are assessed and the development of important nursing skills, such as teamwork and communication.

description: Recent progress in generative AI technology has made audio deepfakes remarkably more realistic. While current research on anti-spoofing systems primarily focuses on assessing whether a given audio sample is fake or genuine, there has been limited attention on discerning the specific techniques to create the audio deepfakes. Algorithms commonly used in audio deepfake generation, like text-to-speech (TTS) and voice conversion (VC), undergo distinct stages including input processing, acoustic modeling, and waveform generation. In this work, we introduce a system designed to classify various spoofing attributes, capturing the distinctive features of individual modules throughout the entire generation pipeline. We evaluate our system on two datasets: the ASVspoof 2019 Logical Access and the Multi-Language Audio Anti-Spoofing Dataset (MLAAD). Results from both experiments demonstrate the robustness of the system to identify the different spoofing attributes of deepfake generation systems.

description: La durabilité des structures en béton armé est devenue une préoccupation majeure pour toutes étapes de construction : la conception, la réalisation et la maintenance de ces ouvrages. La durée de vie est en grande partie liée à la durabilité du matériau mis en œuvre, d’où le béton est estimé plus durable s’il résiste à la pénétration d’agents agressifs. Contrairement aux actions mécaniques, les actions environnementales ne sont pas réversibles et accumulent des composants dangereux dans le béton comme les ions chlorures. La mauvaise estimation de la gravité des actions environnementales cause un pourcentage élevé de dommages à des structures en béton armé. Ces dernières auront besoin d’être réparé après une courte durée de vie. Aujourd’hui, la restauration et la réparation des structures en béton armé est presque aussi importante que de nouvelles constructions. La corrosion des armatures est l’un des principaux phénomènes déterminants pour la durée de vie de la structure. A cet effet, les résultats des travaux expérimentaux présentés dans cet article sont le fruit d’un travail qui est à mi-parcours. Il s’agit d’essais de laboratoire effectués essentiellement sur des bétons ordinaires à l’état durci ou plusieurs bancs d’essais ont été mis au point en vue d’évaluer le risque de corrosion à l’aide d’essais non destructifs « appareil CANIN+ ». Les résultats obtenus à l’aide de ces mesures révèlent une diminution du potentiel de corrosion pour les éprouvettes confectionnes en béton armé dans un milieu agressif (contenant 3% NaCl) par rapport au milieu de référence. Le déroulement des essais dans les différents milieux confirme l’agressivité de l’environnement sur les structures et l’intérêt de l’enrobage.

description: Le développement d’outils de prédiction du comportement macroscopique des matériaux hétérogènes comme les bétons, par une approche micromécanique, nécessite la connaissance à la fois de la microstructure et des lois d’interaction locales. Cette étude porte sur la simulation numérique d’un essai de cisaillement bi-matériaux prenant en compte les propriétés mécaniques de l’interphase « pâte de ciment-granulat » ainsi que leur évolution au cours de l’hydratation. Un modèle d’endommagement basé sur une approche cohésive est utilisé pour caractériser le comportement mécanique de l’interphase. Des simulations numériques de l’essai de cisaillement ont été effectuées avec la plateforme logicielle LMGC90, développée au LMGC, dans laquelle plusieurs modèles de zone cohésive sont implémentés. Une modélisation par éléments finis de l’essai de cisaillement en 3D sur un composite « pâte de ciment-granulat calcaire » a été réalisée. Ces simulations permettent notamment un calibrage rigoureux des paramètres locaux des modèles cohésifs.

Fuel cell battery hybrid (hydrail) propulsion for zero emissions freight switching locomotives : duty cycle construction, component sizing, and low power vehicle prototyping
Creators: name: Hegazi, Mohamed
Publisher: name: University of British Columbia

description: The transport sector is a major contributor to greenhouse gas emissions globally with up to 14% of global emissions. It is one of the most difficult to decarbonize as evidenced by an increased proportion in localities with renewable energy grids. For example, approximately 38% of British Columbia’s GHG emissions come from transport due in part to 87% of its electricity production coming from hydro power. The railway sector presents a unique opportunity to start decarbonizing transport since railway vehicles operate on fixed tracks and therefore present less of a logistical challenge. Railway networks rely on nodes called yards to assemble and disassemble trains for dispatching. Locomotives that operate in these yards are called switcher or shunter locomotives and unlike mainline locomotives they do not travel long distances and rarely leave the yard. Switcher locomotives contribute disproportionately higher levels of emissions on a per unit volume of fuel basis when compared to mainline freight or passenger locomotives. It is reported that switcher locomotives produce almost twice as much nitrogen oxides and particulate matter emissions as mainline freight locomotives, more than twice the hydrocarbons (HC) emissions, and similar levels of carbon monoxide (CO) and sulfur oxide emissions. Switcher locomotives have an aggravated impact on human health as they often operate in and around railway yards that are often located inside cities (population centers). Switcher locomotives present a unique opportunity to apply hydrogen fuel cell battery hybrid (hydrail) technology as a zero emissions solution. This research addresses a gap in knowledge related to the understanding of switcher locomotive duty cycles (power demand) and the sizing of the major components in a hydrail retrofit. An in-service switcher locomotive was instrumented with sensors and a duty cycle was synthesized. In addition, a methodology for sizing the major components in a hydrail retrofit was presented. A technology demonstrator named Hydrail One was prototyped to demonstrate the viability of the technology for locomotive applications and to be used as a research and educational platform to advance knowledge in this field.

description: Ce travail présente les résultats des essais effectués sur un matériau atypique prélevé en Guadeloupe. Le but de ce travail est d’étudier la susceptibilité de ce matériau vis-à-vis de la liquéfaction. Une caractérisation mécanique du matériau a été effectuée via des essais triaxiaux monotones. Ces essais ont permis d’estimer l’angle de frottement du matériau à 38°. L’étude de la susceptibilité à la liquéfaction via les critères basés sur les paramètres de plasticité, n’a pas permis d’avoir une appréciation exacte de la susceptibilité à la liquéfaction du matériau. En effet, certains critères le classait comme fortement liquéfiable, d’autres le classifiait comme non liquéfiable. Les essais au laboratoire ont monté que la liquéfaction de ce matériau ne se produisait que pour de fortes valeurs de déviateur cyclique ce qui correspond à des séismes de forte amplitude.
