Abstract:
the article examines the activities of Titus Labienus, Caesar’s legate in Gaul and a prominent commander in Pompey’s army during the Civil War. His biography is known with large lacunas, as are his political leanings. In Caesar’s Gallic campaigns Labienus served as a legatus pro praetore and proved himself to be a talented military commander. But the fact that he had been praetor before this seems doubtful. With the outbreak of the civil war Labienus defected to Pompey. The motive seems to have been his unsatisfied ambition. After Pompey’s death, Labienus took part in the fight against Caesar in Africa and Spain. Changing sides, Labienus left himself no choice but to fight to the end.

Abstract:
Distributed POMDPs provide an expressive framework for modeling multiagent collaboration problems, but NEXP-Complete complexity hinders their scalability and application in real-world domains. This paper introduces a subclass of distributed POMDPs, and TREMOR, an algorithm to solve such distributed POMDPs. The primary novelty of TREMOR is that agents plan individually with a single agent POMDP solver and use social model shaping to implicitly coordinate with other agents. Experiments demonstrate that TREMOR can provide solutions orders of magnitude faster than existing algorithms while achieving comparable, or even superior, solution quality.

Abstract:
Autophagy is an evolutionarily conserved lysosome-dependent degradation of cytoplasmic constituents. The system operates as a critical cellular pro-survival mechanism in response to nutrient deprivation and a variety of stress conditions. On top of that, autophagy is involved in maintaining cellular homeostasis through selective elimination of worn-out or damaged proteins and organelles. The autophagic pathway is largely responsible for the delivery of cytosolic glycogen to the lysosome where it is degraded to glucose via acid α-glucosidase. Although the physiological role of lysosomal glycogenolysis is not fully understood, its significance is highlighted by the manifestations of Pompe disease, which is caused by a deficiency of this lysosomal enzyme. Pompe disease is a severe lysosomal glycogen storage disorder that affects skeletal and cardiac muscles most. In this review, we discuss the basics of autophagy and describe its involvement in the pathogenesis of muscle damage in Pompe disease. Finally, we outline how autophagic pathology in the diseased muscles can be used as a tool to fast track the efficacy of therapeutic interventions.

Abstract:
Background and Purpose Pompe disease is an inherited disorder notable for severe, progressive ventilatory compromise. Although ventilatory failure has been attributed to myofiber dysfunction secondary to diaphragmatic glycogen accumulation, neural involvement of the phrenic motor system is also a prominent feature. Direct diaphragm pacing supplements respiratory function in other disorders of the phrenic motor system. Accordingly, it is hypothesized that augmented neuromuscular activity via diaphragm pacing would promote weaning from mechanical ventilation in patients with Pompe disease who are unresponsive to conventional, muscle-directed treatments. Case Description Three patients with Pompe disease developed diaphragm paresis that resulted in chronic mechanical ventilation dependence. After preoperative inspiratory muscle strengthening exercises failed to improve function, fine-wire pacing electrodes were laparoscopically implanted into the diaphragm. Diaphragm conditioning was initiated the first postoperative week and consisted of gradual increases in stimulation parameters, lengthening of stimulation sessions, and ventilator weaning. Ventilation and intramuscular electromyographic activity were recorded periodically during conditioning to quantify diaphragm neuromuscular function. Outcomes During paced breathing without mechanical ventilation, tidal volumes increased, and 2 patients were weaned from daytime ventilator dependence within the first 3 months of pacing, which has been sustained over the long-term. A third patient reduced reliance on daytime ventilation, but weaning was delayed by malacia of the large airways. In all patients, pacing appeared to facilitate spontaneous phrenic motor unit activity during independent breathing without ventilator or pacer support. Discussion The findings are consistent with the view that diaphragm pacing has potential rehabilitative value to reduce reliance on mechanical ventilation in people with Pompe disease, but further study is needed. Diaphragm pacing represents a paradigm shift in the management of respiratory insufficiency for Pompe disease that warrants further controlled examination.

Abstract:
Nella Galleria Colonna di Roma si trova un ritratto poco considerato di uno delle figure più significative, e lui stesso a sua volta poco considerato, della storia dei primi venticinque anni del XVI secolo a Roma: il Cardinale Pompeo Colonna. I fini di questo articolo sono due: innanzitutto identificare il reale artista di quel ritratto, precedentemente attribuito a Lorenzo Lotto, ma in questa sede identificato come Sebastiano del Piombo; e, in secondo luogo, restituire al Cardinale Pompeo il giusto grado di importanza in questo momento critico della storia del papato e di Roma. Il tema dell'articolo sarà quindi ampliato al fine di comprendere i percorsi che avrebbero reso possibile l'incontro tra il patrono e l'artista, e dimostrare come queste particolari contatti — qui riferiti come ‘imperiali’ — offrano una nuova via per collegare la carriera di Sebastiano del Piombo a Roma.

La campaña de Cn. Pompeyo Magno (cos. I 70 a.C.) en la isla de Sicilia durante el año 82 a.C., en el marco de la Primera Guerra Civil (88-81 a.C.), no es muy conocida. No sólo figura de puntillas en obras sobre el mencionado conflicto, sino que en diversas biografías de este personaje apenas se menciona su estancia. En el presente trabajo queremos presentar las acciones que realizó Pompeyo, tanto de carácter positivo (impartir justicia, establecimiento de lazos clientelares, la via Pompeia ) como negativo (ejecución de M. Valerio Sorano [tr. pl. 82 a.C.] y de Cn. Papirio Carbón [cos. II 82 a.C.], lo que le valió el calificativo de adulescentulus carnifex ). The campaign of Cn. Pompey the Great (cos . I 70 BC) on the island of Sicily during the year 82 B.C., in the framework of the First Civil War (88-81 BC), is not well known. Not only does he figure on tiptoe in works on the aforementioned conflict, but in several biographies of this character his stay is hardly mentioned. In this paper we want to present the actions that Pompey carried out, both positive (to provide justice, establishment of clientties, the via Pompeia ) and negative (execution of M. Valerius Soranus [tr . pl . 82 BC] and Cn. Papirius Carbo [cos. II 82 BC], which earned him the qualification of adulescentulus carnifex ).

Metrics and distances in probability spaces have shown to be useful tools for physical purposes. Here we use this idea, with emphasis on Jensen Divergences and relative entropies, to investigate features of the road towards the classical limit. A well-known semiclassical model is used and recourse is made to numerical techniques, via the well-known Bandt and Pompe methodology, to extract probability distributions from the pertinent time-series associated with dynamical data.

Full text
Abstract:
La glycoprotéine P ou Pgp est une protéine de transport transmembranaire qui a pour rôle principal d'évacuer hors des cellules les xénobiotiques et les toxines. Elle agit comme une pompe à efflux et est surexprimée par certaines cellules cancéreuses. Ainsi, via ce mécanisme, les cellules tumorales peuvent devenir résistantes aux antitumoraux et conduire à l'échec des traitements lors de la chimiothérapie anticancéreuse. Aussi, la modulation de l'activité de cette protéine peut être un des moyens permettant l'amélioration des traitements anticancéreux. La Pgp possède plusieurs sites de fixation de substrats dont deux sont relativement proches spatialement : un site à stéroïdes et un site à ATP permettant d'hydrolyser l'ATP, source d'énergie nécessaire au fonctionnement de la Pgp. Notre objectif a été de synthétiser des modulateurs bivalents stéroïdes/bras/nucléosides. Pour cela, nous avons dans un premier temps préparé des analogues de bases puriques et plus particulièrement des didéazapurines, les 5- et 6-azaindoles et les trioxopyrrolopyridines correspondant puis effectué la glycosylation de ces derniers. Dans un second temps, des modulateurs stéroïdiens ont été synthétisés : plusieurs ont montré une bonne activité modulatrice de la Pgp. Enfin, des bras polyéthylènes glycols de longueurs variables ont été reliés à l'adénine pour être ensuite fixés aux stéroïdes via une fonction amide
P-glycoprotein Pgp is a transmembrane transporter protein that protects cells from potentially toxic exogenous compounds. This protein acts as a molecular pump and is overexpressed in cancer cells. So via that mechanism, tumor cells exhibit intrinsic or acquired cross-resistance to diverse chemotherapeutic agents, resulting in the failure of chemotherapy for some cancers. The modulation of the efflux activity of that protein can be one of the mean that could increase anticancer treatments efficiency. Pgp has different substrates sites, two of which are spatially close : the steroid site and the ATP site, the latter is in charge of ATP hydrolysis which give the required energy for the Pgp efflux activity. Our goal was to synthesize bivalent modulators steroids/linker/nucleosides. First we have obtained purine bases analogues and particularly didéazapurines such as 5- and 6-azaindoles and the corresponding trioxopyrrolopyridines, then we have carried out the glycosylation of those compounds. Then, steroids modulators have been synthesized : some of them have shown a good modulation activity toward Pgp. Finally, polyethylene glycols chains with different length have been grafted on adenine so that they could be attached to the steroids via an amide function

L'objectif global était d'évaluer la diversité génétique d'une collection de variétés de pommes de terre indigènes originaires de l'île de Chiloé, pour caractériser la résistance de ces variétés au mildiou (Phytophthora infestans) et pour en savoir davantage sur l'état de conservation in-situ. Les sujets suivants a été élaboré: a) la conservation in situ de Solanum indigènes à l'île la grande de Chiloé et son impact sur la diversité, b) l'évaluation de la diversité morphologique des pommes de terre indigènes que nous avons recueillis c) l'évaluation de la diversité génétique par marqueurs microsatellites et AFLP, d) la caractérisation du terrain et des résistances in-vitro au mildiou. Sur la base des résultats des enquêtes, nous pouvons conclure que le maintien in situ de la diversité de pommes de terre indigènes n' est pas bien conservé, en raison des forts changes sociaux et économiques sur l'île de Chiloé. Il y a un processus clair de remplacer les variétés indigènes pour les cultivars commerciaux en réponse aux conditions du marché. Les variétés natives sont présents dans 80,5% des fermes de Chiloé, mais la diversité a été considérablement réduite. Les résultats de la diversité morphologique ont montré la formation de groupes sous le nom populaire et des attributs locaux affectés par les agriculteurs eux-mêmes. L'évaluation moléculaire de la collection (SSRs et AFLP) révèle un haut degré de diversité génétique.

The overall objective was to assess the genetic diversity of a collection of native potato varieties originating from the island of Chiloe, to characterize the resistance of these varieties to late blight (Phytophthora infestans) and to inquire about the status of in-situ conservation. The following specific topics was developed: a) conservation in-situ of native Solanum within the great isle of Chiloe and its impact on diversity, b) evaluation of the morphological diversity of the native potatoes that we have collected c) assessment of genetic diversity of the collection by the mean of microsatellite and AFLP markers, d) characterization of field and in-vitro resistances to late blight. Based on the results of the surveys, we can conclude that in-situ maintenance of native potato diversity i is not well preserved, due to strong social and economic changes on the island of Chiloe. There is a clear process of replacing native varieties for commercial cultivars in response to market conditions. Native varieties are present in 80.5% of the farms of Chiloe, but the diversity of varieties has been significantly reduced. The results morphological diversity showed the formation of groups under the popular name and local attributes assigned by the farmers themselves. Molecular evaluation of the collection (SSRs and AFLP) reveals a high degree of genetic diversity. Both markers were consistent in classifying Solanum fernandezianum as the more distant genotype compared to all the others. The SSRs allowed the estimation of the polymorphic information content for seven loci which values ranged between 0.63 to 0.89. Both types of markers, did not provide the same groupings among the accessions. The SSR-based study showed a low differentiation between native potatoes and improved cultivated varieties. The analysis of diversity based on the AFLP was not inconsistent with this result because despite containing only one cultivar (Desiree), the cultivar was grouped with the native varieties. In relation to resistance to late blight, most accessions of native potato fall into the ranks moderately resistant to moderately susceptible

L’étude de la durabilité des élastomères des stators des pompes Moineau a été menée en utilisant à la fois des simulations numériques, des essais thermomécaniques et des analyses physico-chimiques. Les simulations numériques ont eu pour principal objectif de permettre de déterminer la localisation et le niveau des maximums des champs mécaniques dans le stator. Les essais ont permis quant à eux de caractériser le comportement mécanique du matériau élastomère sous sollicitations mécaniques cycliques à différentes températures. Une première étude a permis d’analyser l’évolution de l’effet Payne en fatigue. Une seconde s’est concentrée sur l’analyse de l’effet de l’application d’un chargement thermomécanique sur l’évolution de la microstructure du matériau élastomère
The study of the sustainability of the rubber, which is the main constitutive material of the Moineau pump stator, was carried out using finite element analyses, thermomechanical experiments and physic-chemical analysis. The numerical simulations were performed to identify the range and location of the maximal stress and strain within the pump stator. The experimental tests allowed to characterize the mechanical behaviour of rubber under cyclic solicitation at several temperatures. The first part of the study focused on the Payne effect during fatigue loading while the second dealt with the effect of a thermomechanical loading on the rubber microstructure evolution

In the area of the investigated shops, the nearly complete removal of all the floors, carried out in the first part of the nineteenth century, has allowed a detailed study of the stratigraphic layers to take place and to collect information, not only about several building phases between the end of the third century BC and 79 AD, but also about the socio-economic picture of the period. In particular, the pottery assemblage discarded near a series of small structures, mostly built in earth and wood, and probably used as latrines (II century BC), provides interesting clues about the ceramic used by the families who frequented the space in that period of time.

Abstract:
Les infections infantiles constituent une problématique majeure en termes de morbi-mortalité à l'échelle mondiale, contribuant significativement aux décès infantiles, notamment via les infections respiratoires. Les facteurs de risque d'infection grave chez les nourrissons sont multifactoriels, principalement liés au développement in utero, à la prématurité, au faible poids de naissance, ainsi qu'à des facteurs immunologiques, génétiques et environnementaux. Les données récentes dans la littérature montrent que des modifications du microbiote peuvent avoir des répercussions au niveau immunitaire et potentiellement accroître le risque infectieux. Ainsi des modifications du microbiote materno-foetal pourraient avoir des conséquences chez le nourrisson. La littérature récente suggère l'existence d'associations entre une exposition in utero aux antibiotiques et l'augmentation du risque d'infections graves chez les nourrissons. Ces études ont été rendues possibles notamment grâce au développement de la pharmaco-épidémiologie via l'usage des bases médico-administratives, tel que le Système National des Données de Santé (SNDS), permettant la constitution de cohortes conséquentes de femmes enceintes. L'objectif global de cette thèse consistait en l'évaluation du rôle d'expositions médicamenteuses pendant la grossesse et le risque d'infections graves au cours de la première année de vie. Les travaux ont été centrés sur l'étude de deux classes pharmacologiques en raison de leur usage fréquent au cours de la grossesse et de leur impact sur le microbiote materno-foetal : les antibiotiques et les inhibiteurs de la pompe à protons. Dans un premier temps, une étude de cohorte nationale, incluant 2,8 millions de nourrissons nés à terme, a évalué l'association entre l'exposition in utero aux antibiotiques systémiques et l'apparition d'infections graves au cours de leur première année de vie. Les résultats ont montré une augmentation modérée de l'incidence des infections graves chez les nourrissons exposés in utero aux antibiotiques. Les associations étaient similaires quel que soit le trimestre d'exposition, la classe d'antibiotiques, ainsi que le site d'infection. Néanmoins, les nourrissons exposés à des antibiotiques à large spectre ou à trois cures ou plus au cours de la grossesse semblaient avoir un risque légèrement accru, en faveur d'une relation causale. Dans un second temps, une autre étude, stratifiée sur la consommation d'inhibiteurs de la pompe à protons au cours des trois premiers mois de vie et incluant 2,1 millions de nourrissons nés à terme, a exploré l'impact de l'exposition prénatale aux inhibiteurs de la pompe à protons sur la survenue d'infections graves pendant leur première année de vie. Les résultats ont permis d'éliminer une association importante entre la consommation d'inhibiteurs de la pompe à protons au cours de la grossesse et la survenue d'infections graves chez le nourrisson. Néanmoins, même après la prise en compte de nombreux facteurs de confusion, cette étude n'a pas permis d'exclure un risque résiduel, restreint uniquement aux nourrissons qui ne reçoivent pas d'inhibiteurs de la pompe à protons durant les premiers mois de vie. En conclusion, cette thèse a confirmé les données existantes sur une association entre l'exposition aux antibiotiques au cours de la grossesse, médicaments impactant fortement le microbiote, et la survenue d'infections graves chez le nourrisson. Les résultats sont plus rassurants concernant les inhibiteurs de la pompe à protons même si un risque faible ne peut être exclu. Ces résultats sont à confirmer avec d'autres études. Ils ont contribué à élargir la base de connaissances relatives à la sécurité d'utilisation des médicaments au cours de la grossesse
Infant infections are a major concern in terms of global morbidity and mortality, significantly contributing to infant deaths, particularly through respiratory infections. Risk factors for severe infections in infants are multifactorial, primarily related to in utero development, prematurity, low birth weight, as well as immunological, genetic, and environmental factors. Recent data in the literature suggest that modifications in the microbiome can have immunological implications and potentially increase the risk of infection. Therefore, changes in the maternal-fetal microbiome could have consequences for the infant. Recent literature suggests associations between in utero exposure to antibiotics and an increased risk of serious infections in early childhood. These studies have been made possible, in particular, through the development of pharmacoepidemiology using medical-administrative databases, such as the National Health Data System (SNDS), allowing the creation of substantial cohorts of pregnant women. The overall objective of this thesis was to evaluate the role of medication exposures during pregnancy and the risk of serious infections in the first year of life. The research work focused on two pharmacological classes due to their frequent use during pregnancy and their impact on the maternal-fetal microbiome: antibiotics and proton pump inhibitors. Firstly, a national cohort study, including 2.8 million full-term infants, evaluated the association between in utero exposure to systemic antibiotics and the occurrence of serious infections in full-term infants during their first year of life. The results revealed a moderate increase in the incidence of serious infections in infants exposed in utero to systemic antibiotics. Associations were similar regardless of the trimester of exposure, antibiotic class, and infection sites. However, infants exposed to broad-spectrum antibiotics or three or more antibiotic courses appeared to have a slightly increased risk, supporting a potential causal relationship. Secondly, another study, stratified by the use of proton pump inhibitors during the first three months of life and including 2.1 million full-term infants, explored the impact of prenatal exposure to proton pump inhibitors on the occurrence of serious infections during their first year of life. The results ruled out a significant association between the use of proton pump inhibitors during pregnancy and the occurrence of serious infections in infants. Nevertheless, even after adjusting for several confounding factors, this study did not exclude a limited residual risk, restricted only to infants with proton pump inhibitors use in early life. In conclusion, this thesis confirmed existing data on an association between exposure to antibiotics during pregnancy, which strongly affects the microbiome, and the occurrence of serious infections in infants. The results are more reassuring concerning proton pump inhibitors; although a low risk cannot be completely ruled out. These findings need confirmation through further studies. They have contributed to expanding the knowledge regarding the safety of medication use during pregnancy

Abstract:
Le processus d'urbanisation en Chine exerce une forte pression sur l’environnement. Le plus fort potentiel de réduction de ces impacts correspond aux décisions prises lors de la conception du bâtiment, qui peuvent s’appuyer sur des outils de simulation numérique. Cette thèse est consacrée à l’étude de trois conditions aux limites liées à l'évaluation de la performance énergétique et environnementale des bâtiments en Chine : - Le sol : un modèle de pompe à chaleur couplée au sol est proposé, et couplé à un modèle d'échangeur de chaleur géothermique permettant le calcul rapide de la réponse d’un champ de sondes verticales de grande taille. Ce modèle peut être utilisé pour améliorer les performances énergétiques du système en phase de conception ou de gestion. - Le microclimat : une méthode de génération de fichier climatique spécifique au site qui fournit la température horaire locale de l'air est proposée, prenant en compte l'effet d'îlot de chaleur urbain. Les effets du microclimat sur la performance énergétique du bâtiment sont étudiés quantitativement. - Le système d’arrière-plan pour l’analyse de cycle de vie : les effets de la variation spatiale et temporelle du mix de production d'électricité en Chine sur les impacts environnementaux sont étudiés. La base de données environnementales est adaptée au contexte national et local chinois. Les résultats montrent que les impacts environnementaux des bâtiments peuvent être évalués plus raisonnablement en considérant ces trois conditions aux limites
The urbanisation process in China brings a high pressure on the environment. The highest potential to reduce these impacts corresponds to decisions made during the building’s design phase, which can be supported by numerical simulation. This thesis is dedicated to the study of three boundary conditions related to the energy and environmental performance evaluation of buildings in China: - The ground: a ground coupled heat pump model is proposed integrating a fast calculation ground heat exchanger model for a large-scale boreholes field. This model can be used to improve the energy performance of the system in the design and operation phases. - The microclimate: a site-specific weather file generation method which can provide local hourly air temperature is proposed, accounting for the urban heat island effect. The effects of the microclimate on the building’s energy performance are quantitatively investigated. - The background system for life cycle assessment: the effects of the spatial and temporal variation of the electricity production mix in China on the environmental impacts are investigated. The environmental database is adapted to the Chinese national and local context. The results show that the environmental impacts of buildings could be more reasonably evaluated by considering these three boundary conditions

Abstract:
AbstractInter-cellular heterogeneity is central to the dynamic range and robustness of function in many tissues, particularly electrically excitable tissues. In pancreatic islet 𝛽-cells, inter-cellular heterogeneity underlies the range of insulin response to glucose. In human-induced-pluripotent stem cell-derived cardiomyocytes (hiPSCCMs), inter-cellular heterogeneity presents a key challenge for drug screening applications. In this study, we assess the ability to reconstruct inter-cellular heterogeneity in silico by applying a “population of models” (PoMs) framework, i.e. collections of computational cells created via Monte Carlo variation of model parameters. We define parameter variation based on experimentally observed heterogeneity in properties such as ion current conductances and enzymatic affinities. We then assess the accuracy of those reconstructions, based on the degree to which variation in PoM outputs (e.g. action potential duration) matches experimentally observed variation. We report that this “ground-up” approach underestimates functional heterogeneity in the hiPSC-CM population, but overestimates it in adult human cardiomyocytes. In contrast, the 𝛽-cell PoM captures three distinct and physiologically relevant subclasses of 𝛽-cell function. In the future, we expect PoM approaches like these willpermit incorporation of realistic cellular heterogeneity in detailed models of intact tissues, and thereby aid development of sophisticated tissue-engineered platforms for therapeutics.

Abstract:
Abstract We investigate the interpretation of proper orthogonal modes (POMs) of displacements in both linear and nonlinear vibrations. The POMs in undamped linear symmetric systems can represent linear natural modes if the mass distribution is known. This is appoximately true in a distributed system if it is discretized uniformly. If a single mode dominates, the dominant POM approximates the dominant mode. This is also true if a distributed system is discretized arbitrarily. Generally, the POMs represent the principal axes of inertia of the data in the coordinate space. For synchronous nonlinear normal modes, the dominant POM represents a best fit of the nonlinear modal curve. Linear and nonlinear simulation examples are presented.

Abstract:
Abstract We apply proper orthogonal decomposition (POD) to an experimental cantilevered beam and obtain a set of proper orthogonal modes (POMs) and proper orthogonal values (POVs). The POMs form a bases that represents the optimal distribution of energy in the system. A set of experiments was performed excited by impulse inputs and sensed with strain gages. The strains were converted to displacements and POD was performed on the displacements. The POMs were compared with the theoretical normal modes. The results confirmed the validity of this method for acquiring lower modes of vibration. The identification of lower modes was robust with respect to the choice of data acquisition parameters and input locations. We also used different types of basis functions for converting strains to displacements.

Abstract:
We study the problem of policy synthesis for uncertain partially observable Markov decision processes (uPOMDPs). The transition probability function of uPOMDPs is only known to belong to a so-called uncertainty set, for instance in the form of probability intervals. Such a model arises when, for example, an agent operates under information limitation due to imperfect knowledge about the accuracy of its sensors. The goal is to compute a policy for the agent that is robust against all possible probability distributions within the uncertainty set. In particular, we are interested in a policy that robustly ensures the satisfaction of temporal logic and expected reward specifications. We state the underlying optimization problem as a semi-infinite quadratically-constrained quadratic program (QCQP), which has finitely many variables and infinitely many constraints. Since QCQPs are non-convex in general and practically infeasible to solve, we resort to the so-called convex-concave procedure to convexify the QCQP. Even though convex, the resulting optimization problem still has infinitely many constraints and is NP-hard. For uncertainty sets that form convex polytopes, we provide a transformation of the problem to a convex QCQP with finitely many constraints. We demonstrate the feasibility of our approach by means of several case studies that highlight typical bottlenecks for our problem. In particular, we show that we are able to solve benchmarks with hundreds of thousands of states, hundreds of different observations, and we investigate the effect of different levels of uncertainty in the models.
