description: The Pleiades is a young open cluster that has not yet dynamically relaxed, making it an ideal target to observe various internal dynamical effects. By employing a well-defined sample of main-sequence (MS) cluster members, including both MS single stars and unresolved MS+MS binaries, we revisited their individual masses and mass functions and quantified the mass dependence of their radial distributions. We found that the mass function of binaries is more top-heavy than that of single stars. Significant mass segregation is observed for both single and binary populations respectively, with more massive objects concentrated towards the cluster center. Notably, within given mass ranges, binaries are distributed more scattered than single stars, providing direct evidence for more efficient dynamical disruption of binaries in the inner region. The radial distribution of the binary fraction, expressed as the $f_{\rm b}-R$ relation can be characterized by a bimodal shape, with higher $f_{\rm b}$ values in both innermost and outermost regions of the cluster. The lower-mass subsample exhibits a monotonic increase in $f_{\rm b}$ with radius, reflecting the impact of binary disruption. Conversely, for the higher-mass subsample, $f_{\rm b}$ decreases with radius. It can be explained that these massive cluster members, which possess higher binary probabilities, have already undergone significant mass segregation. All these observational evidence and analyses related to the radial mass distribution imply that the Pleiades is currently undergoing a complicated interplay of various internal dynamical effects, of which the modulation between mass segregation and binary disruption is particularly pronounced.

The Healthy Immigrant Effect and LGBTQ+ Asian Canadians
Creators: name: Shima, Tsuba
Publisher: name: The University of British Columbia

description: Health is a huge issue when it comes to the Asian diaspora for numerous reasons – cultural barriers, traditional systems of medicine, discrimination, and other factors all play an important role. The discussion that needs to take place with greater prominence is understanding how racialization, gender, and sexual orientation all intersect with each other to better explain and account for variability in health. Tsuba conducts a comprehensive review to examine whether or not such intersectionality matters when examining health disparities. In particular, do conventional health trends regarding racialized settlers in Canada replicate for racialized LGBTQ+ folks, and what implications does this have for future research involving this topic?

description: Pseudogenes are fossil relatives of genes. Although pseudogene sequences are highly similar to gene sequences, accumulation of mutations has disabled pseudogenes from producing protein products. Pseudogenes might present a reservoir of genetic diversity. Key mutation signatures in pseudogenes indicate the history of gene evolution. In this study, we develop a novel approach integrating graph analysis, sequence alignment and functional analysis to investigate gene-pseudogene relationships, and generate the first set of gene-pseudogene families in human. For each family, we perform conservation analysis from sequence alignment, and identify the mutation signatures (both conserved and non-conserved sites), which might contribute to enabling/disabling protein coding ability, thus have functional impact on the genome.
title: An Investigation into Oral Digital Storytelling in Primary English in Switzerland
Creators: name: Lustenberger, Andrea
Publisher: name: The Open University
Year: 2022

description: This thesis investigates oral digital storytelling (DST) in the young learner foreign language (L2) classroom and was motivated by my practice as a Swiss primary teacher and English language methodology lecturer at the teacher training college in Zug. To date, there has been little research on the potential role of oral task-based DST in the L2 classroom at primary level. This year-long study explores opportunities and challenges of collaborative oral task-based DST in English L2 classes in a Year 4 primary classroom (ten-year-olds). It examines how L2 learning can be promoted, and what prior knowledge is needed to engage in the tasks. It further explores the effect of collaborative DST on speaking proficiency, and the use of language(s) - and notably translanguaging. The main data consist of video- and audio-recordings of four pupils working in dyads on collaborative oral tasks, and semi-structured interviews with the children and their Year 4 teacher. My original research and data-collection plans were significantly affected by the COVID-19 lockdown, making adaptations necessary. These included: analysis of an English lesson observed before lockdown; an individual DST task for the children to complete as part of home-schooling; a pupil questionnaire about their different experiences of DST in pairs at school and at home alone; and an interview with the children’s Year 5 teacher to gain some qualitative insights into her perception of the impact of DST on the children’s English. The data were analysed using reflexive thematic analysis and the underlying approach to the research was ecological constructivism. The findings suggest that DST can provide a bridge between the mandated textbook to connect it with the children’s lives and play a motivating role in supporting the development of L2 oracy, particularly where supported by: the explicit teaching of effective collaborative work; the provision of task-based language support resources; and the presence of an audience. A further significant finding was the positive role of using L1 and translanguaging in the L2 classroom. Translanguaging, little-known in Switzerland, is unsupported by Curriculum 21, the recently implemented curriculum to harmonise education across the various cantons in Switzerland. My findings also give insights into how structured oral task-based DST can enhance pupils’ oracy in an L2, pupils’ and teachers’ Information and Communication Technology skills, and pedagogy more generally – an important set of findings given the necessity for more theoretical insights in technology-supported task-based DST.

description: En France comme dans le reste du monde, en raison du réchauffement climatique, de la croissance démographique et de la pollution, l'approvisionnement en eau devient un enjeu important. Pour résoudre ce problème, le stockage et/ou la récupération et purification de l'eau impropre à la consommation sont envisagées. L'évaporation solaire, qui fait l'objet de recherches depuis plusieurs années, est une méthode de purification qui utilise l'énergie du rayonnement solaire pour vaporiser l'eau puis la condenser et la récupérer pour la consommation humaine. Le système consiste à placer un matériau à la surface de l'eau pour accélérer son évaporation. Ce matériau doit capter suffisamment bien le rayonnement solaire, tout en permettant à l'eau de diffuser vers la surface d'évaporation. De plus, le matériau doit limiter les transferts thermiques vers l'eau liquide, afin de conserver l'énergie en surface. Jusqu'à présent, les études sur le sujet ont été principalement expérimentales, utilisant différents types de matériaux et de méthodes sans validation numérique des hypothèses émises. L'objectif du travail présenté est de proposer un modèle numérique permettant de simuler les performances d'évaporation du système, de confirmer les hypothèses avancées dans la bibliographie, et d'étudier l'impact des conditions aux limites hygrothermiques . Un modèle axisymétrique 2D, qui inclut la modélisation des transferts thermiques ainsi que du transfert d'eau vers la surface, a été choisi. Ainsi, deux équations couplées comprenant la conservation de la masse d'eau liquide et l'équation de la chaleur ont été utilisées et implémentées dans un logiciel de modélisation par éléments finis (COMSOL 5.6). Pour valider ce modèle, plusieurs expériences ont été réalisées en utilisant une mousse poreuse biosourcée à base de tanin de mimosa. Le tanin est un composant extrait du bois, qui, dans le cas du mimosa, est présent dans les écorces. Les mousses de tannin sont donc faciles à produire et ont un faible impact environnemental. En outre, elles sont poreuses à 95 \% et permettent le transport de l'eau jusqu'à la surface d'évaporation. En ajoutant une couche de peinture à base de graphite pour améliorer l'absorption du rayonnement solaire, elles font un maté
‘I don’t feel like I am desirable’ : Internalized racism among Asian GBM and MSM and the subsequent health consequences
Creators: name: Bawaan, Nathan
Publisher: name: The University of British Columbia
Year: 2022

description: Nathan writes about the experiences of Asian Gay and Bisexual Men (GBM) and men who have sex with men (MSM), and the struggles that they often have to deal with – systemic racism within LGBTQ+ communities, the resulting internalized racism, and how both impact their mental health. As Nathan explains, Asian GBM and MSM exist in a system in which they sometimes reject their own ethnic identities and idealize Whiteness (and particularly White gayness), often out of a desire to fit into LGBTQ+ spaces. This piece dovetails nicely with Tiffany Ou’s animation about the stripping down of the fight for queer liberation into effectively a gay White man’s struggle. Nathan points out that this kind of self-loathing, to the point of not recognizing oneself as being desirable, presents particularly difficult mental health challenges for Asian GBM and MSM – with extremely concerning physical health implications, too. How, then, can Asian GBM MSM find community within LGBTQ+ spaces, or must they create their own?

description: (Au. D.) -- Towson University, 2017.
description: The purpose of this study was to examine commonalities between patient case history complaints, diagnoses, and test results, and cases presented in the literature. Patient files of individuals seen for audiological testing at the Towson University Institute for Well Being were reviewed. The total number of active, inactive, and archived audiology patient files totaled 2,554. Patients with a diagnosis of sensorineural hearing loss and poorer-than-expected word recognition scores, compared to Dubno et al. (1995), met study criteria. The number of patient files that met study criteria, and were included in statistical analysis, was 231 after exclusions (n = 163). Data were analyzed to determine any numerical (i.e., PTA, WRS) or case history complaints (i.e., difficulty in noise) significantly predicted poorer than-expected word recognition scores. Patient pure-tone average (average of 500 Hz, 1000 Hz, and 2000 Hz) was the only significant predictor of poor word recognition scores. Individuals with sudden sensorineural hearing loss appeared to have markedly decreased word recognition scores, and individuals with OAE notches ≥15 dB appeared to have better word recognition scores, on average, compared to the individuals who did not present with this case history; however, inferential statistics were not calculated on this sub-population due to the small sample size. Future research should focus on a prospective study to determine statistical significance of case history variables, and additional rehabilitation options for individuals with poor word recognition abilities.

Filipino Representation in Media and Colonial Mentality among Second-Generation Filipino Immigrants in North America
Creators: name: Abando, Gabrielle
Publisher: name: The University of British Columbia
Year: 2022

description: The Philippines is an infinitely diverse country with a rich precolonial and postcolonial history. Notably, though, the several centuries of colonization inevitably left their indelible mark on the Philippines in things like beef caldereta, champorado, and spamsilog. As benign as those examples might be, colonialism had more insidious effects, most notably affecting the psychology of the local population. This effect, more generally referred to as a colonial mentality, has impacted consequential aspects of life including standards of beauty, social stratification that prizes Whiteness, migratory aspirations, and Western idealization. In considering these issues, Gabrielle presents a research proposal to address a greatly important question: To what extent do second-generation North American Filipino diaspora identify with media about Filipinos and how does this facilitate distance or proximity to their Filipino ethnic identities?

Can we predict infants’ evaluations of bullies?

description: Humans often characterize other individuals based on shared interests, language, status, and other traits. This can even be seen in infants as young as eleven months old, who prefer puppets that share the same food preference as themselves (Mahajan & Wynn, 2012). Infants also prefer to harm individuals dissimilar to them (Hamlin et al., 2013). Many studies have found that infants present certain moral and prosocial behaviours to individuals depending on their similarities (Botwin et al., 1997; Brewer, 2016; Cikara et al., 2011; Weisel & Böhm, 2015). However, few studies have explored what factors play a role in an infant’s ability to differentiate and categorize similar and dissimilar individuals and further use these categorizations to make moral judgments. This current exploratory study uses a longitudinal approach to examine whether their preference for similar individuals at 12 months old, cognitive processing and deliberation speed at 17 months old can predict their preference in hindering a dissimilar puppet at 17 months old. Chi-square analysis showed that their preference for similar individuals at 12 months old is not significantly associated with harming a dissimilar character at 17 months old, ꭓ2 (1, n = 27) = 1.74, p = .19. A binary logistic regression also showed that age (b = 0.2855, SE = 0.52, p = .58), cognitive processing speed (b = 0.4128, SE = 0.37, p = .27), and latency to choose (b = -0.6843, SE = 0.52, p = .19) also do not significantly predict an infant’s ability to understand the complex task at 17 months old. Though these results are insignificant and there are multiple limitations in this current study, there may still be many factors that can predict how and why infants have selective moral and prosocial behaviour. Understanding infants’ perceptions of social situations can further explain how certain preferences, and possibly even biases, develop throughout our lives.

description: Devant le défi majeur de la réduction de l'impact des activités humaines sur le changement climatique, le secteur des bâtiments représente en France un domaine dans lequel il existe un fort potentiel en termes de réduction des consommations d'énergies fossiles et de production de gaz à effet de serre. Dans ce contexte, l'enveloppe de bâtiment figure parmi les principaux axes d'amélioration, en matière d'isolation mais aussi en gérant de manière efficace les interactions avec l'environnement. L'équipe habitat du LGCgE à Béthune travaille depuis plusieurs années sur la conception et le développement de parois multifonctionnelles, actives ou passives (murs solaires, parois ventilées, etc…). Ces parois sont moins déperditives, voir même à bilan positif du fait de la récupération d'apports solaires et d'énergies fatales. Le travail présenté ici s'inscrit dans le cadre du projet « VARIETO » - ADEME NTE Nouvelles technologies émergentes, réalisé par un consortium de deux équipes universitaires et un industriel de la menuiserie. Le but est de concevoir et analyser le comportement d'une fenêtre pariétodynamique à triple vitrage chauffant. Celle-ci est conçue pour assurer à la fois le chauffage, la ventilation et l'éclairage naturel à l'intérieur d'un bâtiment. Son principe de fonctionnement consiste à faire circuler et à chauffer de l'air neuf provenant de l'extérieur entre les lames de vitrage avant son introduction dans le local à chauffer. La recherche présentée dans cette communication via les approches numériques et expérimentales, concerne plus particulièrement le comportement thermique et dynamique de l'écoulement d'air interne lorsque la fenêtre est équipée d'un vitrage chauffant. Du fait de la géométrie du composant, des zones de recirculation, dites « zones mortes », se forment et perturbent la dynamique de l'écoulement et les échanges de chaleur. On discutera ici de la notion de coefficient d'échange convectif dans ces zones, et des difficultés qui se présentent au niveau de la définition des températures de fluide de référence. En particulier, les températures de mélanges dans ces zones hétérogènes, s'avèrent très complexes à déterminer. Un modèle numérique a été établi en comparaison avec des expérimentations réalisées en cellules climatiques. Plusieurs pistes ont été explorées numériquement pour montrer qu'il est possible de faire fonctionner la fenêtre à différents débits optimaux.

description: La disponibilité limitée des combustibles fossiles conventionnels comme le gaz naturel a renforcé l'intérêt de la diversification des sources d'énergie afin d'assurer des ressources durables suffisantes à la demande combinée en chaleur et en électricité. Les ressources renouvelables non-conventionnelles que sont les biogaz, les syngaz and les biocarburants sont de bons postulants à ces objectifs de diversification énergétique, particulièrement dans un contexte de production décentralisée telle que l'utilisation de micro turbines à gaz dans une application de cogénération de faible puissance. De plus, ils présentent l'avantage majeur de réduire les émissions de CO2 afin d'atteindre les objectifs climatiques à l'horizon 2050. Cependant, dus à leurs propriétés spécifiques telles leur pouvoir calorifique inférieur, leur composition variable ainsi que leur fraction de vapeur d'eau importante quand ils ne sont pas correctement post-traités, une meilleure caractérisation des sources d'énergies renouvelables non-conventionnelles est requise. L'objectif de ce travail est donc d'identifier le comportement de plusieurs syngaz dans une chambre de combustion industrielle, spécifiquement conçue pour le gaz naturel. Dans ce travail, l'analyse des résultats de simulations numériques d'une chambre de combustion alimentée au syngaz est présentée. Les performances de la chambre de combustion est analysée pour différentes compositions de syngaz avec injection progressive de vapeur d'eau dans le but de déterminer la teneur maximale admissible en vapeur et limiter le post-traitement dans la production des gaz synthétiques. L'allumage et la stabilité de flamme ont été particulièrement étudiés avec une distribution de gaz variée entre la flamme pilote et la flamme principale. Les résultats montrent le champ de température, les prédictions précises des espèces de réactions intermédiaires et des NOx, CO, CO2 et H2O dans les fumées, qui sont de même nature que les précédentes observations. Plus spécifiquement, il a été trouvé que le NOx sont particulièrement sensibles aux modifications de distribution de combustible entre la flamme pilote et la flamme principale. Ces résultats obtenus pourront servir de références pour la caractérisation future de gaz synthétiques bruts dans une large gamme de conditions d'utilisation, ce qui permettra d'exploiter entièrement leur potentiel dans des applications de cogénération de faible puissance.

description: The University of British Columbia (UBC) has a unique urban food production site, known as the UBC Farm (“the Farm”), next to a coastal hemlock forest that harbors a variety of local bat species. Bat populations are currently declining worldwide and face many threats such as the critical fungal disease known as white-nose syndrome (WNS). These threats could potentially compromise the ecosystems services bats provide to their environment. Moreover, WNS could be especially devastating to the vulnerable communities of the little brown bat (Myotis lucifugus) which was the most observed bat species at the Farm. For these reasons, it is important to understand and document the current state of these populations. This research investigates the temporal patterns and spatial distributions of bat biodiversity by analyzing bat calls recorded from 2019-2021. Potential phenological shifts were detected but require long-term monitoring to confirm these conclusions. Furthermore, the effect of land cover on bat activities was explored but limited due to small sample sizes. This effect was also likely masked by the little brown bats' roosting preference for forest-edges and man-made structures. Findings of bat activities contributed to better understanding these bat populations at UBC. This research was the first to uncover bat biodiversity trends at the Farm and provide support for the local bats conservation as a means to protect the agro-ecosystem and ensure food security.

description: With the increasing prevalence of online learning, adapting education to diverse learner needs remains a persistent challenge. Recent advancements in artificial intelligence (AI), particularly large language models (LLMs), promise powerful tools and capabilities to enhance personalized learning in online educational environments. In this work, we explore how LLMs can improve personalized learning experiences by catering to individual user needs toward enhancing the overall quality of online education. We designed personalization guidelines based on the growing literature on personalized learning to ground LLMs in generating tailored learning plans. To operationalize these guidelines, we implemented LearnMate, an LLM-based system that generates personalized learning plans and provides users with real-time learning support. We discuss the implications and future directions of this work, aiming to move beyond the traditional one-size-fits-all approach by integrating LLM-based personalized support into online learning environments.

description: Large language models have been used to translate natural language questions to SQL queries. Without hard constraints on syntax and database schema, they occasionally produce invalid queries that are not executable. These failures limit the usage of these systems in real-life scenarios. We propose a neurosymbolic framework that imposes SQL syntax and schema constraints with unification-based definite clause grammars and thus guarantees the generation of valid queries. Our framework also builds a bi-directional interface to language models to leverage their natural language understanding abilities. The evaluation results on a subset of SQL grammars show that all our output queries are valid. This work is the first step towards extending language models with unification-based grammars. We demonstrate this extension enhances the validity, execution accuracy, and ground truth alignment of the underlying language model by a large margin. Our code is available at https://github.com/ML-KULeuven/deepstochlog-lm.

description: The past few years developments in advanced cycle modifications aimed at making micro Gas Turbines (mGTs) more fuel and operational flexible. However, accurate data, on real industrial combustor configuration, assessing the performances and emissions of the combustion under unconventional diluted conditions or fuels involved by these novel cycles are still missing. In this framework, Large Eddy Simulations, which allow to accurately assess the unsteady effects coupled to turbulent-chemistry interaction of reacting flows, offer an opportunity to better assess the combustion behavior under these specific conditions. However, the computational cost still remains much higher than RANS simulations. Moreover, an adequate mesh has to be generated to perform valid LES. However, for such complex geometries, the mesh generation might be complex, especially when the region of interest is not intuitively known. In this work, a dynamic adaptive mesh refinement strategy is proposed and applied on the LES of a typical industrial mGT combustor, the Turbec T100. This strategy consists in automatically refining the mesh along the simulation only in regions where finer cells are required to capture essential effects, i.e. the flame front, at a reasonable cost. Thus, the flame sensor, allowing to identify the flame front location, is used as adaptation criterion. The triggering of the mesh adaptation over time is based on the relative metric error, representing the deviation from the desired mesh metric. The results show that the adaptation strategy allows to generate automatically a dynamic mesh that is able to capture correctly the flame. Moreover, although the mesh adaptation process has a non-negligible calculation cost, a much heavier static mesh would be required to achieve the same resolution accuracy. However, this strategy, simply based on the flame sensor, does not allow the automatic and correct meshing of the dilution zone at the combustion chamber outlet, which is necessary to predict emissions and flue gas properties precisely. Therefore, to ensure a fully automatic meshing of the combustion chamber to avoid human intervention, an additional adaptation criterion must be considered.

description: Nitrogen-containing drug molecules and pharmaceuticals are ubiquitous, rendering the construction of C−N bonds a crucial target in methodology development. The Ritter reaction is a well-established method for accessing C−N bonds by generating amide functionality through the reaction of carbocations and nitriles. Since its discovery back in 1948, the Ritter reaction has progressively advanced towards milder and more sustainable conditions for carbocation generation. In this regard, notable contributions have been made by means of single electron transfer (SET) chemistry. Nowadays, photo- and electrochemistry are established methods of choice for the generation of reactive radical intermediates and their subsequent oxidation via radical-polar crossover (RPC) mechanism. We review recent examples of tandem RPC and Ritter-type protocols, demonstrating how photo- and electrochemical energies have been effectively harvested to expand the precursor pool for the Ritter reaction as well as reimagining the process with novel mechanisms and additives.

description: Lors d'un accident hypothétique de perte de réfrigérant au primaire (APRP) dans un réacteur à eau pressurisée (REP), de l'eau est injectée dans le plenum du cœur afin de refroidir les assemblages. Due à l'élévation de la température des assemblages au cours du transitoire, un écoulement constitué de vapeur avec des gouttes dispersées se forme en aval du front de remouillage. Cet écoulement permet de refroidir les parties d'assemblages non encore immergées par l'eau. La caractérisation des transferts thermiques dans ces zones est indispensable pour s'assurer que les assemblages puissent être refroidis même s'ils sont déformés. Afin de caractériser ces transferts, une boucle expérimentale, appelée COLIBRI, a été construite. Cette boucle a permis de déterminer le flux de chaleur dégagé par un écoulement vapeur/gouttes à l'échelle d'un sous-canal combustible intact ou déformé en conditions thermo-hydrauliques typiques d'un APRP. D'autre part, COLIBRI a permis la validation d'un code, appelé NECTAR, qui a été développé dans le but de calculer le transfert de chaleur et de masse, ainsi que la dynamique des gouttes dans un écoulement polydispersé dans les mêmes conditions géométriques et thermo-hydrauliques que COLIBRI. L'analyse des premiers résultats expérimentaux avec NECTAR a montré que la convection entre la vapeur et la paroi est le mécanisme de transfert le plus important dans le calcul du flux interne de chaleur mais le transfert de chaleur par impacts de gouttes à la paroi est également non négligeable. Ces résultats obtenus avec une température d'entrée de vapeur et une fraction volumique des gouttes faibles qui ne permettent pas de valider l'ensemble des corrélations sur toute la gamme des écoulements attendus en APRP (Tv=180$^{\circ}$C et $\alpha$g~10-4). Afin d'analyser l'influence des différents mécanismes de chaleur dans ces configurations thermo-hydrauliques étendues, la boucle expérimental COLIBRI a été modifiée, afin d'augmenter la fraction volumique des gouttes ($\alpha$g~2.10-3) et la température d'entrée de la vapeur (Tv= 500 $^{\circ}$C). Finalement, le but de cet article est de comparer les résultats du code NECTAR avec les données expérimentales obtenues avec la nouvelle configuration de la boucle COLIBRI (sous-canal non bouché de 100mm de longueur). La dissipation thermique interne totale est évaluée et les contributions des différents mécanismes impliqués sont analysées.

Thermal conductivity

description: The thermal characterization at micro or nano scale is of great interest for numerous of technical and technological applications. Assessment of heat transfer at microscale permits understanding behavior and design of different kind of systems like microelectronic or micro-electro-mechanical devices or effective properties of composite materials.\\ In this context, at I2M laboratory, we use widely the photothermal methods for thermal characterization of thin layer materials. One of these methods is the modulated photothermal radiometry (MPTR) which is well adapted to measure the out of plane thermal properties of thin films. The modulated photothermal radiometry is a contactless measurement technique based on monitoring the emitted infrared radiation from the surface of the sample consequently to a periodic photothermal excitation. The photothermal power from a modulated laser source is absorbed by the surface of the sample leading to an increase in the temperature at the heating area. This results in an increase in the infrared emitted radiation and assuming small temperature increase the emitted radiation can be linearized. On this way an indirect measurement of the temperature at the sample surface is obtained. In this work, we intend to develop a fast photothermal radiometry with several tenth of microns in resolution in order to enable the in plane thermal characterization. With the use an optical arrangement we manage the formation of the heating and measurement spots at the sample surface. The heating spot of 15 $\mu$m in diameter is formed by focusing the laser; the measurement spot of 50 $\mu$m in dimeter is an image of the detector over the sample surface. The sample mounted over a translation stage permits it's scanning with micrometric precision. The use of modulated excitation allows exploring the frequencies up to 50 kHz. Under this configuration the in plane and out of plane heat conduction is possible to be assessed.

description: During the last decade, known as the “Genomic Era”, the gap between sequence determination and functional annotation has increased dramatically, representing an incomplete understanding of the data we have generated. Automatic annotation pipelines ease the burden of manual annotation, but are limited in scope and coverage. Computational tools for proteome annotation are intrinsically conservative in assigning a definitive function (76% in UniProt/TrEMBL are annotated as "unknown" or "uncharacterized") and tend to focus on specific aspects of the protein such as functional domains, signal peptide prediction, or the a in its environment. Integrating results from several databases and tools allows us to simultaneously question several aspects of a protein's function. We have created a computational pipeline that combines the advantages of manual curation with the speed and power of bioinformatics. The pipeline is modular, open-source, can be installed at your location or run on our server. The pipeline allows the characterization of whole proteomes as well as single proteins. We applied the computational Integrative Cell Biology (cICB) pipeline to 40 bacterial proteomes belonging to the PVC superphylum and were able to increase the average number of annotated proteins from 54% to 78%. We illustrate some of the advantages of cICB with some global and detailed results. The PVC results are available at www.pvcbacteria.org/pvcbacteria

description: Le Laboratoire National de Métrologie et d'Essais a développé une installation de référence pour effectuer des mesures de diffusivité thermique par méthode "laser flash" jusqu'à 3000 $^{\circ}$C. Cette installation a été adaptée à la détermination de la capacité thermique massique des matériaux aux très hautes températures par calorimétrie à chute. Dans cette installation, un échantillon, mis dans un creuset et suspendu par un fil métallique très fin en tantale (diamètre 50 \si{\micro\metre}) via une pince motorisée, est chauffé dans un four inductif. Lorsque l'équilibre thermique est atteint, le creuset et l'échantillon chute dans un bloc calorimétrique situé sous le four et maintenu à une température proche de la température ambiante. Un obturateur mécanique mobile est placé au-dessus du calorimètre pour limiter le rayonnement du four vers le calorimètre pendant les phases de chauffe. Les variations d'enthalpie de l'échantillon entre sa température initiale dans le four et la température du calorimètre sont mesurées par étapes en fonction de la température initiale dans le four. Plusieurs creusets ont été fabriqués et utilisés pour effectuer des essais à vide et avec les matériaux à tester afin de s'affranchir des pertes thermiques de l'échantillon lors de la chute. La dérivation de la courbe de variation d'enthalpie de l'échantillon par rapport à la température initiale dans le four conduit à la capacité thermique massique. L'étalonnage en énergie du calorimètre est effectué par substitution électrique dans des conditions expérimentales identiques à celles des mesures grâce à un système d'étalonnage in-situ développé spécifiquement pour ce calorimètre. Des mesures de variation d'enthalpie et de capacité thermique massique à haute température ont été réalisées sur plusieurs matériaux solides (alumine, tungstène, graphite). L'enthalpie de fusion du cuivre pur a aussi été mesurée en effectuant des chutes à l'état solide et à l'état liquide et en déterminant la variation d'enthalpie liée à la congélation. Cette communication décrit la mise au point du calorimètre à chute à haute température et la procédure qui a été développée afin de mesurer des incréments d'enthalpie et d'en déduire la capacité thermique massique.

description: A method of computing the derivative of any automaton is presented, based on Brzozowski's work on derivatives of regular expressions and Might, Darais, and Spiewak's work on derivatives of context- free grammars. Equivalence with Brzozowski's and Might et al.'s derivatives are proven, but practical applications depend on other means of constructing automata.

description: Context. Binary asteroids are present in all populations of the Solar System, from near-Earth to trans-Neptunian regions. As is true for the small Solar System bodies (SSSBs), binary asteroids generally offer valuable insights into the formation of the Solar System, as well as its collisions and dynamic evolution. In particular, the binaries provide fundamental quantities and properties of these SSSBs, such as mass, angular momentum, and density, all of which are often hidden. The direct measurement of densities and porosities is of great value in revealing the gravitational aggregates and icy bodies that form the asteroid-comet continuum. Aims. Several observation techniques from space and ground-based platforms have provided many results in this regard. Here we show the value of the Gaia mission and its high-precision astrometry for analysing asteroid binaries and for individually deriving the masses of the components. Methods. We focus on the binary asteroid (4337) Arecibo, a member of the Themis family. We analysed the astrometry obtained in the Gaia FPR catalogue release, and performed orbital fitting for both the heliocentric orbit of the system and the relative orbit of the binary components. Results. We obtain an estimation of the component masses and their flux ratio, and derive bulk densities rho1 = 1.2 and rho2 = 1.6 for the primary and the secondary, respectively. The results are consistent with an ice-rich body in the outer main belt. They also show a significantly denser secondary or a less closely packed primary. Constraints on these densities and on macroscopic porosities are nevertheless limited by our poor knowledge of the sizes of the components. Observations of future mutual events, and of stellar occultations predicted in 2024 - 2025, will be essential for improving our knowledge of this system and its formation.
