description: In this letter, we investigate the properties of a strongly interacting spinless Fermi gas close to a $p$-wave resonance. We show that the universal properties at a $p$-wave resonance are captured by two contacts, which are related respectively to the variation of energy with the $p$-wave scattering volume $v$ and with the effective range $R$ in the two adiabatic theorems derived. We show how the two contacts determine the leading and sub-leading asymptotic behavior of the momentum distribution ($\sim 1/k^2$ and $\sim 1/k^4$) and how they can be measured experimentally by radio-frequency, Bragg, and photo-association spectroscopies. Finally, we evaluate the two contacts at high temperature via the virial expansion.

Development of novel nanomedicines for the treatment of non-small cell lung cancer
Creators: name: Cryer, Alexander Martyn
Publisher: name: Imperial College London
Year: 2020

description: Lung cancer stands as one of the deadliest diseases, responsible for the most cancer related deaths worldwide. The UK 5-year survival rate of non-small-cell lung cancer (NSCLC), the predominant subtype of lung cancer, stands at 9.5%, highlighting an unmet need for therapeutic intervention. A key issue is the lack of efficacy current chemotherapy regimens have in the clinic. These therapies often suffer from poor tumour targeting, resulting in dissemination throughout the body and inadequate concentrations in the tumour. This causes deleterious side effects contributing to a reduced patient quality of life and ultimately survival. Nanomedicine may serve to overcome the current therapeutic hurdles in treating NSCLC; the use of nanoparticles (NPs) for the delivery of drugs can improve drug targeting to tumours, increasing efficacy and attenuating off-target side effects. NPs can be used to deliver multiple drugs and be made from varying materials such as gold (AuNPs) or polymers. Furthermore, the discovery of oncogenic mutations in genes like EGFR present druggable targets in patients harbouring the appropriate mutations. This can also be taken advantage of using NPs to more directly target tumours and increase therapeutic response. Therefore, the aim of this thesis was to develop novel NP formulations comprised of a chemically modified variant of the tyrosine kinase inhibitor afatinib and gold (Afb-AuNPs) or in combination with vinorelbine as a polymeric dual chemotherapy formulation (Dual-NPs). Drug-bearing NPs were synthesised using a combination of organic chemistry and hydrophobic ion pairing, after which the NPs were extensively characterised to discern their physicochemical properties. We then sought to investigate the in vitro efficacy of NPs. Cell viability studies revealed Afb-AuNPs and Dual-NPs were significantly cytotoxic to various NSCLC cell lines and comparatively nontoxic to noncancerous cells. Moreover, NP formulations were found to significantly inhibit proliferation of A549, H226 and PC-9 cells 3 compared to clinical formulations as determined by electric cell-substrate impedance sensing. The mechanism of uptake in cancer cells was elucidated using fluorescent NPs as a model system and quantified using confocal microscopy. Finally, the in vivo activity of biocompatibility of Dual-NPs was investigated in a physiologically relevant murine model of NSCLC. Taken together, these results highlight the therapeutic potential for NP formulations of chemotherapy.

description: The present habilitation project encompasses research on multiple and complex levels of mental health care preferences and expectations, support systems, psychological mechanisms, as well as novel and culturally sensitive treatment approaches for RAS who primarily stem from Arabic- and Farsi-speaking countries. Until today, there are still enormous mental health treatment gaps for RAS, regardless of the country of residence. The current investigations shed light on a variety of facets, including preferences and expectations on psychotherapy (Böge et al., 2021), the key role of perceived stress and social support on psychopathology (Böge et al., 2020), as well as the representation of symptoms and the influence of stigma in refugee populations (Lindheimer et al., 2020). Moreover, we could show that emotional regulation appears to be a vital psychological mechanism mediating the effect between early life stress and the development of psychiatric symptoms, suggesting a direction for personalized psychotherapeutic interventions in refugees (Demir et al., 2020). In a last step, we developed a novel stepped collaborative and care model, which proved the effectiveness and cost-effectiveness in alleviating depressive symptoms of adolescent and adult RAS compared to routine mental health care in Germany (Böge et al, 2022). Against this background, the outcomes of this habilitation project are relevant because they outline where cultural barriers lie, showcase possible ways of overcoming those and depict a suitable, scalable, and collaborative intervention approach. Our outcomes pave the way for resource-saving, cost-efficient, and tailored psychological interventions, specifically for humanitarian aid and international settings with low human and financial resources. In challenging times and impending decades, in which large-scale migration movements and pandemics significantly increase the relevance of global mental health, our findings are especially valuable. Consequently, outcomes of the present work make key contributions to and have implications and a meaningful influence on the immediate and long-term mental health and its provision for RAS worldwide.
The regulation of CDK activity by cyclins
Creators: name: Basu, Souradeep
Publisher: name: Imperial College London
Year: 2020

description: In eukaryotes, the two major cell cycle events of DNA replication and chromosome segregation are directed by Cyclin Dependent Kinases (CDKs) in combination with G1/S cyclins (S-CDK) and G2/M cyclins (M-CDK), respectively. It is still unclear what differentiates S-CDK activity from M-CDK activity, and how much functional redundancy exists between cyclin-CDK complexes. Here the fission yeast G1/S cyclin-CDK complex, Cig2-Cdc2, is used to study S-CDK. It is shown that S-CDK is capable of achieving high levels of CDK activity, but is incapable of executing mitosis. However, deletion of Protein Phosphatase 1 (PP1) allows for mitotic progression, and is therefore responsible for restricting S-CDK from executing mitosis. Substrates at the yeast centrosome equivalent, the spindle pole body (SPB), are phosphorylated poorly by S-CDK. Consistent with this idea, removal of PP1 at the SPB alone allows S-CDK to drive mitosis. Phosphoproteomic analysis then shows that S-CDK and M-CDK have subtly different in vivo CDK substrate preferences, but that the majority of substrates experience S-CDK and M-CDK activity equally. Using a CDK mutant that does not need cyclin binding for activity, evidence is presented suggesting that generic CDK activity without cyclins is sufficient for S-phase, but that cyclin-associated CDK activity is required for mitosis. In pursuit of why cyclins are essential for mitosis, the substrate docking region of the mitotic cyclin Cdc13 is mutated. The mutation of this region does not affect Cdc13-dependent S-phase progression, but cells fail to execute mitosis. Mutant Cdc13 is unable to localise correctly to the interphase SPB, and phosphoproteomic analysis suggests that this defect causes reduced CDK substrate phosphorylation at the SPB, preventing mitosis. These data are consistent with the idea that cyclins regulate CDK localisation at mitosis to influence CDK substrate selection, and suggests that correctly regulated CDK activity across cellular compartments is needed to execute mitosis.

description: In this master thesis we study the derived invariance of Hochschild cohomology, a notion of great significance as it records meaningful algebraic and geometric information, under two types of derived equivalences. The first type of derived equivalence is given by the so-called derived Morita theorem and in this case it follows effortlessly that Hochschild cohomology is indeed a homological invariant. However, when we restrict our attention to a special class of algebras, named Koszul algebras, and study the Koszul duality functor, we show that, although we have a triangle equivalence between certain derived categories, the Hochschild cohomology is not preserved under such equivalences. Fortunately, we resolve this problem by working in the right framework, which turns out to be very nicely captured by differential graded categories. In this context, we manage to lift the isomorphism between the Hochschild cohomologies to a weak equivalence of the Hochschild cochain complexes, using a theorem of Bernhard Keller. Finally, we show that this weak equivalence, preserves the higher structure of Hochschild cohomology and refines the already known invariance results.

Ο πρώτος τύπος παραγόμενης ισοδυναμίας δίνεται από το περίφημο παραγόμενο θεώρημα Morita και σ' αυτή την περίπτωση έπεται αβίαστα ότι η συνομολογία Hochschild είναι πράγματι μια ομολογική αναλλοίωτη. Ωστόσο, όταν περιορίζουμε την έρευνά μας σε μια ειδική κλάση αλγεβρών, ονόματι άλγεβρες Koszul, και μελετάμε τον συναρτητή δυϊκότητας των αλγεβρών Koszul, παρόλο που έχουμε μια τριγωνισμένη ισοδυναμία μεταξύ συγκεκριμένων παραγόμενων κατηγοριών, βλέπουμε ότι η συνομολογία Hochschild δεν διατηρείται. Ευτυχώς η επίλυση του προβλήματος αυτού είναι εφικτή, δουλεύοντας στις σωστές δομές, οι οποίες αποτυπώνονται όμορφα από τις differential graded κατηγορίες. Στο πλαίσιο αυτό, καταφέρνουμε να ανυψώσουμε τον ισομορφισμό των συνομολογιών Hochschild, σε μια ασθενή ισοδυναμία μεταξύ των συμπλόκων Hochschild, χρησιμοποιώντας ένα θεώρημα του Bernhard Keller. Τέλος, αποδεικνύουμε ότι αυτή η ασθενής ισοδυναμία διατηρεί την ανώτερη δομή της συνομολογίας Hochschild και βελτιώνει τα ήδη γνωστά αποτελέσματα της ομολογικής αναλλοίωσης.

description: Glucagon (GCGN) plays a key role in glucose and amino acid (AA) metabolism by increasing hepatic glucose output. AA strongly stimulate GCGN secretion which regulates hepatic AA degradation by ureagenesis. Although increased fasting GCGN levels cause hyperglycemia GCGN has beneficial actions by stimulating hepatic lipolysis and improving insulin sensitivity through alanine induced activation of AMPK. Indeed, stimulating prandial GCGN secretion by isocaloric high protein diets (HPDs) strongly reduces intrahepatic lipids (IHLs) and improves glucose metabolism in type 2 diabetes mellitus (T2DM). Therefore, the role of GCGN and circulating AAs in metabolic improvements in 31 patients with T2DM consuming HPD was investigated. Six weeks HPD strongly coordinated GCGN and AA levels with IHL and insulin sensitivity as shown by significant correlations compared to baseline. Reduction of IHL during the intervention by 42% significantly improved insulin sensitivity [homeostatic model assessment for insulin resistance (HOMA-IR) or hyperinsulinemic euglycemic clamps] but not fasting GCGN or AA levels. By contrast, GCGN secretion in mixed meal tolerance tests (MMTTs) decreased depending on IHL reduction together with a selective reduction of GCGN-regulated alanine levels indicating greater GCGN sensitivity. HPD aligned glucose metabolism with GCGN actions. Meal stimulated, but not fasting GCGN, was related to reduced liver fat and improved insulin sensitivity. This supports the concept of GCGN-induced hepatic lipolysis and alanine- and ureagenesis-induced activation of AMPK by HPD.

description: In literature, there have been many studies on the liquefaction of soil; however, most of them are to study the liquefaction of saturated soil and it is necessary to have more results on the liquefaction of unsaturated soil. In this study, a series of triaxial test on both saturated and unsaturated samples was carried out to have better understand of the liquefaction of unsaturated sand in very dense state. All the samples were reconstituted using wet tamping method at a relative density of 83%. After wetting and consolidating, the samples were subjected to cyclic loading with stepping Cyclic Stress Ratio (CSR). The results shows that the saturation degree affects significantly liquefaction potential of soil. The decrease of saturation degree results on the decrease of liquefaction potential of soil. Besides, the effects saturation degree on the friction angle and the slope of failures lines at the liquefaction state were also considered.

description: What makes this review essay on Francisco Cantúʼs bestselling book on the US-Mexican border regimes uniquely thought-provoking – and, in equal measure, challenging – is the diversity of the disciplines involved and their relationship to the subject matter. Our working groupʼs aim has been to analyze notions of ›subjectivation‹, that is, the process of becoming a subject in relation to practices of vigilance. Thus, our working group explored what different disciplines can gain from reflecting on and analyzing the same text and which aspects of it they consider particularly relevant to ongoing debates on vigilance and subjectivation. What kind of subtexts are brought to light by these divergent readings and what aspects do some disciplines stress that others would not have noticed in such detail?

description: La résistance à la compression du béton est l'un des paramètres mécaniques les plus importants dans l'évaluation des performances mécaniques des structures en béton armé. La méthodologie récente de l’évaluation de la résistance mécanique du béton d’un ouvrage existant combine des mesures de contrôle non destructif (CND), comme la mesure du rebond et la mesure de la vitesse de propagation des ondes ultrasonores, avec des mesures destructives (prélèvements) de manière à développer un modèle de conversion, entre la résistance mécanique et les mesures non destructives. Le modèle de conversion est utilisé pour estimer ensuite la valeur locale de la résistance à chaque emplacement des mesures non destructives et de représenter ainsi la variabilité spatiale. Le but de cette étude est de proposer une nouvelle méthodologie basée sur l'optimisation multi-objective pour prédire la résistance à la compression du béton et sa variabilité sur la base des mesures CND. À cette fin, une large base de données expérimentale et synthétique d'essais destructifs et non destructifs a été utilisée. Les conclusions tirées des données synthétiques seront confrontées aux résultats obtenus sur la base de données réelle afin de tester le potentiel de la méthodologie proposée. Cette étude montre le principe de la méthodologie et les premiers résultats de son efficacité pour prédire la résistance à la compression et sa variabilité.

description: Engineering long-range interactions in experimental platforms has been achieved with great success in a large variety of quantum systems in recent years. Inspired by this progress, we propose a generalization of the classical Hamiltonian mean-field model to fermionic particles. We study the phase diagram and thermodynamic properties of the model in the canonical ensemble for ferromagnetic interactions as a function of temperature and hopping. At zero temperature, small charge fluctuations drive the many-body system through a first-order quantum phase transition from an ordered to a disordered phase. At higher temperatures, the fluctuation-induced phase transition remains first order initially and switches to second-order only at a tricritical point. Our results offer an intriguing example of tricriticality in a quantum system with long-range couplings, which bears direct experimental relevance. The analysis is performed by exact diagonalization and mean-field theory.

description: Limiting the amount of greenhouse gas CO2 related to the production of cement is a major issue for industrials and the scientific community. The partial substitution of cement by low carbon impact additions allows the reduction of this impact. In this context, the aim of this study is the formulation of a ternary binder based on flash calcined sediment (FCS) and ground granulated blast-furnace slag (GGBS). This also allows the valorization of dredged sediments. The used materials –ordinary Portland cement (OPC), FCS and GGBS– were physically, chemically and mineralogically characterized. Five formulations, one reference mortar RM (100% OPC), one binary formulation (50% OPC/50% GGBS), and three ternary formulations containing variable FCS rates (10%, 15%, 20%), were characterized fresh and hardened. Results showed the incorporation of FCS reduces workability and increases the density. Also, a reduction of the initial setting time and the peak of the heat of hydration were observed. At the hardened state, the mixture containing 10% FCS showed better mechanical strengths than those of RM at 90 days. This was confirmed by the investigation of the mortars porosity. Moreover, the use of FCS in ternary binders could reduce the environmental impact of concrete and enhance its mechanical performance.

description: La perméabilité est un indicateur de durabilité reconnu permettant d’évaluer entre autres l’étanchéité des ouvrages, notamment du nucléaire, pour lesquels les propriétés de confinement sont essentielles. Plusieurs techniques de mesure sont utilisées pour déterminer une valeur de perméabilité apparente, qui diffère selon la nature de la technique utilisée. La technique de mesure en surpression et régime permanent est la seule à faire l’objet d’une norme (XP-P18-463), la perméabilité obtenue par cette technique sera considérée ici comme perméabilité de référence. Les techniques en dépression (régime permanent ou transitoire) conduisent à une perméabilité supérieure du fait de la nature des écoulements non visqueux mis en jeu et/ou des gradients de pression évolutifs présents dans l’échantillon. L’objectif de l’article est de proposer une méthode d’harmonisation des techniques permettant de remonter à la perméabilité de référence quelle que soit la technique utilisée.

description: The equilibria formed by the self-gravitating, collisionless collapse of simple initial conditions have been investigated for decades. We present the results of our attempts to describe the equilibria formed in $N$-body simulations using thermodynamically-motivated models. Previous work has suggested that it is possible to define distribution functions for such systems that describe maximum entropy states. These distribution functions are used to create radial density and velocity distributions for comparison to those from simulations. A wide variety of $N$-body code conditions are used to reduce the chance that results are biased by numerical issues. We find that a subset of initial conditions studied lead to equilibria that can be accurately described by these models, and that direct calculation of the entropy shows maximum values being achieved.

description: This paper investigates the process of knowledge exchange in inter-firm Research and Development (R&D) alliances by means of an agent-based model. Extant research has pointed out that firms select alliance partners considering both network-related and network-unrelated features (e.g., social capital versus complementary knowledge stocks). In our agent-based model, firms are located in a metric knowledge space. The interaction rules incorporate an exploration phase and a knowledge transfer phase, during which firms search for a new partner and then evaluate whether they can establish an alliance to exchange their knowledge stocks. The model parameters determining the overall system properties are the rate at which alliances form and dissolve and the agents' interaction radius. Next, we define a novel indicator of performance, based on the distance traveled by the firms in the knowledge space. Remarkably, we find that - depending on the alliance formation rate and the interaction radius - firms tend to cluster around one or more attractors in the knowledge space, whose position is an emergent property of the system. And, more importantly, we find that there exists an inverted U-shaped dependence of the network performance on both model parameters.

description: We present the analysis of photometric and spectroscopic data on eight candidates for post-nova systems. Five post-novae, V528 Aql, HS Sge, BS Sgr, GR Sgr and V999 Sgr, are successfully recovered. We furthermore identify likely candidates for the fields of V1301 Aql, V1151 Sgr and V3964 Sgr. The spectroscopic properties of the confirmed post-novae are briefly discussed. We find that two of the oldest post-novae in our sample, GR Sgr and V999 Sgr, contain an optically thick accretion disc, and thus can be suspected to have a high mass-transfer rate, contrary to what one would expect from most models. HS Sge and V528 Aql show evidence for a (comparatively) high system inclination, which makes them attractive targets for time-series observations. Finally, the presence of particularly strong He II emission together with a small eruption amplitude suggests that BS Sgr is a good candidate for an intermediate polar.

Year: 2021

description: This thesis explores the mainstreaming of far-right anti-migrant frames in Sweden and France. Using frame analysis, the thesis documents when three frames transferred from the manifestos of far-right to mainstream parties across three elections. The thesis also examines how discursive opportunities, specifically the visibility of migration, and political context, specifically differences in voter competition and political systems, impacted the transfer of frames. The material includes manifestos published by center, center-right, and far-right parties between 2007-2018 and supplementary data published between 2002-2019, including immigration statistics, vote margins, and party GAL-TAN scores. The thesis concludes that in Sweden, far-right frames did not appear in center-right manifestos in 2010 or 2014, but transferred by 2018. In France, far-right frames appeared in center-right manifestos in 2007 and 2012, but less by 2017. The thesis also finds that in both countries, differences in political context and discursive opportunities, specifically migration visibility, impacted frame transfer.

description: Chains of magnetic adatoms on superconductors have been discussed as promising systems for realizing Majorana end states. Here, we show that dilute Yu-Shiba-Rusinov (YSR) chains are also a versatile platform for quantum magnetism and correlated electron dynamics, with widely adjustable spin values and couplings. Focusing on subgap excitations, we derive an extended t−J model for dilute quantum YSR chains and use it to study the phase diagram as well as tunneling spectra. We explore the implications of quantum magnetism for the formation of a topological superconducting phase, contrasting it to existing models assuming classical spin textures.

description: Providing the neurobiological basis of information processing in higher animals, spiking neural networks must be able to learn a variety of complicated computations, including the generation of appropriate, possibly delayed reactions to inputs and the self-sustained generation of complex activity patterns, e.g.~for locomotion. Many such computations require previous building of intrinsic world models. Here we show how spiking neural networks may solve these different tasks. Firstly, we derive constraints under which classes of spiking neural networks lend themselves to substrates of powerful general purpose computing. The networks contain dendritic or synaptic nonlinearities and have a constrained connectivity. We then combine such networks with learning rules for outputs or recurrent connections. We show that this allows to learn even difficult benchmark tasks such as the self-sustained generation of desired low-dimensional chaotic dynamics or memory-dependent computations. Furthermore, we show how spiking networks can build models of external world systems and use the acquired knowledge to control them.

Οι θρησκευτικές γιορτές στοχεύουν στην ανάπτυξη της έμφυτης θρησκευτικότητας του μαθητή και επιπροσθέτως παρέχουν στους μαθητές /τριες θρησκευτικές αλλά και γνώσεις από άλλα γνωστικά αντικείμενα.
description: This paper deals with religious holidays in Primary School. Originally, a reference is made to the school holidays of the 3 Hierarchs, Christmas and Easter. The relevant legislative framework (laws, circulars, instructions) as well as the Hidden Analytical Program are presented. The religious holidays are described in P.S. and in the Religious Studies course (1977 – 2021). Then, the Curriculum for the Religious Studies course in Primary Education (2020) is mentioned. A comparison is made of the APS and the Religious and Language school textbooks regarding religious holidays. The paper concludes with the presentation of the proposal for a Christmas cross-cultural school celebration. The Christmas holiday is of great importance but at the same time needs special attention from the teacher's side due to the multicultural composition of the school classes. The religious holidays aim to develop the innate religiosity of the student and additionally provide the students with religious knowledge as well as knowledge from other subjects.
Valorisation binaire de la poudre de verre et des déblais argileux calcinées flash par alcali-activation

description: Ce travail s’intéresse à la valorisation de déchets locaux à savoir des déchets de verre (GV), des cendres volantes (CV) et des déblais calcinés Flash. Afin de réaliser une matrice recomposée alcali-activée, une première étape consiste à optimiser l’activateur formé de NaOH (12, 10, 8 et 6 M) et de GV. Les résultats suggèrent que l'augmentation de la quantité de déchets de verre ainsi que l'augmentation de la molarité de NaOH conduisent à une diminution de l’étalement, et à une amélioration de la résistance en compression sur les mortiers. La deuxième étape est l’optimisation des formulations en NaOH (10 et 12 M avec 30% de GV et 70% de CV) pour substituer davantage les CV par les deux déblais (notés AM et FL) calcinés Flash à hauteur de 25%. Les résultats de lixiviation sont conformes aux seuils actuels pour les matières non dangereuses. De même, les résistances à la compression sont améliorées dans les matrices ternaires (GV, CV et AM/FL), notamment dans les matrices avec 12 M en NaOH.

description: Lors des tremblements de terre, les murs en maçonnerie de briques sont vulnérables aux forces de cisaillement et ce, principalement en raison de la faible résistance à la traction et de la grande hétérogénéité des matériaux constitutifs. De nombreuses recherches ont alors été menées sur le renforcement de ce type de mur, par différents composites, avec des résultats plus ou moins probants. Et c'est sur la base de ces résultats que nous avons choisi de tester la résistance aux forces de cisaillement de murs renforcés avec des composites TRM. Nous présentons dans ce qui suit les principaux résultats de ces tests effectués au sein du LMDC de Toulouse.

description: La mobilité est en constante évolution, et les enjeux environnementaux actuels nécessitent une mobilité plus durable. Le projet SwITCh vise à créer un outil d’aide à la réflexion sur ces problématiques de mobilité urbaine à destination de tous les acteurs concernés. Ce travail y contribue en proposant une simulation basée agent des décisions sur le choix des modalités des individus pour le trajet domicile-travail. Ces décisions sont basées à la fois sur des critères rationnels et sur l’habitude. Le but est de pouvoir tester différentes stratégies urbaines en termes d’infrastructures afin de (faire) comprendre leur impact sur le choix modal des individus. En particulier, nous avons implémenté une stratégie d’aménagement de nouvelles pistes cyclables, et montré qu’elle résulte en une augmentation de la part modale du vélo, mais ceci au détriment de la marche à pied et des transports en commun plutôt que de la voiture. Des travaux futurs étudieront d’autres stratégies pour augmenter la part des mobilités douces dans les trajets quotidiens, afin de tendre vers une ville plus durable.

Publisher: name: Academic Journal of Civil Engineering
Year: 2022

description: Cet article présente une étude de caractérisation expérimentale en torsion de poutres hybrides GFRP-bois. Chaque composant élémentaire (poutres bois et profilés GFRP) a d’abord été testé seul en torsion. Puis les composants ont été assemblés par boulonnage et testés à leur tour en torsion dans le domaine élastique. La mesure des rotations a permis d’en déduire les rigidités de torsion pour différentes configurations géométriques. Les résultats expérimentaux ont montré que l’apport du bois augmente significativement la rigidité en torsion des profilés GFRP dans chaque configuration. L'influence de la densité des connecteurs a également été mise en évidence. Une analyse par éléments finis volumiques a été ensuite utilisée pour simuler le comportement en torsion de ces poutres. Les résultats numériques sont en adéquation avec les mesures.

description: Computing the holographic entanglement entropy proposed by Ryu-Takayanagi shows that thermal energy near boundary region in $AdS_3$ gain maximum of the temperature. The absolute maxima of temperature is $T^{Max}_{E}= \frac{4G_3 ε_{\infty}}{l}$. By simple physical investigations it has become possible to predict a phase transition of first order at critical temperature $T_c\leq T_{E}$. As they predict a tail or root towards which the AdS space ultimately tend, the boundary is considered thermalized. The Phase transitions of this form have received striking theoretical and experimental verifications so far.

A TRANSATLANTIC DIVORCE AND THE TIME FOR EUROPEAN SOVEREIGNTY? – A STUDY ON HOW US FOREIGN POLICY, DURING 2010-2020, IMPACTED EU MEMBER STATE VIEWS ON DEFENCE INTEGRATION
Creators: name: Strandquist, Julia Anna Maria
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: This thesis explores the impact of US foreign policy, during 2010-2020, on EU member state willingness to integrate defence, by utilizing a mixed-method approach. The objective is to investigate how EU member states reacted to the Obama administration’s ‘pivot to Asia’ and the election and presidency of Donald Trump and whether those administrations contributed to further defence integration. Quantitative analysis finds that EU member state increased defence expenditures after 2015, which could be a continued response to Russian aggression, Brexit, and Trump threats to the EU and NATO. Qualitative analysis finds no support that the changes in US commitment to Europe impacted the EU member state willingness or arguments for further defence integration. The thesis concludes that as PESCO is a member state-driven initiative, it enables EU member states to pursue projects that align with their self-interests.
Regenerative synthetic ecosystems and evolving asteroid starships: a cybernetic reframing of the politics, poetics and ethics of space colonization

description: Inevitably, there will be a time when humankind transitions from the stage of space exploration to actual space colonization. With colonists living semi-independently from Earth comes the need for self-sustainability. Biology will play a key role here, through the establishment of regenerative life support and agricultural food production systems. In this presentation, two space research projects will be presented that explicitly take the analogy between biology and machines as their departure point. An analysis of both projects' intrinsic politics and the poetics emanating from their idiosyncratic perspectives leads us to shared ethical values. The first project, the MELiSSA research programme of the European Space Agency, focuses on the development of an artificial ecosystem in which human waste is broken down into nutrients for plants by a series of bioreactors. The plants consequently provide the necessary food and oxygen for the crew. The project employs a perspective in which the ecosystem is entirely atomized: life is conceived to be an ongoing exchange of molecules, and the ecosystem a superbody in which all actors sooner or later share the same atoms. This endless exchange and the consequential web-like interdependencies are at the heart of the system's politics. E|A|S (Evolving Asteroid Starships) is a transdisciplinary advanced concept research programme at Delft University of Technology. The bio-inspired concept of an evolvable spacecraft is being explored based on a combination of requirements research, computer modeling, and visual research. This spacecraft is conceived to be an open and responsive life-like entity that is in constant dialogue with its internal and external environment. It achieves this through a combination of asteroid mining and space-based 3D manufacturing. In essence, the spacecraft operationalizes a willingness to change. The machine is conceived here as an endless flow, constantly working against entropy-driven decay. As such it can be considered to be an 'anti-ruin'. The above analysis finally leads to two shared lines of ethics: obsolete obsolescence and responsibility for the Other. In this presentation, these ethics will be further elucidated, and their relevance to life on Earth discussed.
Comportement en flexion des poutres mixtes Composites-Bois

Publisher: name: Academic Journal of Civil Engineering

description: Cet article présente une étude expérimentale du comportement en flexion à court- terme et jusqu’à la rupture, de poutres hybrides innovantes en GFRP-bois. Plusieurs configurations géométriques ont été étudiées avec un mode de connexion entre les poutres bois et les profilés GFRP par boulonnage. Les résultats des essais ont montré un gain remarquable de capacité portante apporté par les poutres en bois qui permettent de retarder le déversement des profilés GFRP. Ce gain dépend principalement de la configuration géométrique. En outre, des simulations numériques de ces poutres par éléments finis dans le domaine élastique ont été effectuées. Les résultats numériques et les mesures présentent des écarts faibles (de l’ordre de 6 %), y compris à l’approche de la rupture. Une étude paramétrique a montré l’influence des propriétés du bois ou de la disposition des boulons sur le comportement des poutres hybrides. Cette étude ouvre la voie à une nouvelle hybridation des matériaux de construction afin d’optimiser leur utilisation dans le secteur de la construction.
