description: The equation of state parameter is a significant method for characterizing dark energy models. We investigate the evolution of the equation of state parameter with redshift using a Bayesian analysis of recent observational datasets (the Cosmic Chronometer data (CC) and Pantheon samples). The Chevallier-Polarski-Linder parametrization of the effective equation of state parameter, $ω_{eff}=ω_0+ω_a \left( \frac{z}{1+z}\right) $, where $ω_0$ and $ω_a$ are free constants, is confined to the Weyl type $f(Q,T)$ gravity, where $Q$ represents the non-metricity and $T$ is the trace of the energy-momentum tensor. We observe the evolution of the deceleration parameter $q$, the density parameter $ρ$, the pressure $p$, and the effective equation of state parameter $ω$. The cosmic data limit for $ω$ does not exclude the possibility of $ω< -1$. It is seen that the parameter $ω$ shows a transition from deceleration to acceleration, as well as a shift from $ω>-1$ to $ω<-1$.

description: This work observationally addresses the relative distribution of total and optically luminous matter in galaxy clusters by computing the radial profile of the stellar-to-total mass ratio. We adopt state-of-the-art accurate lensing masses free from assumptions about the mass radial profile and we use extremely deep multicolor wide--field optical images to distinguish star formation from stellar mass, to properly calculate the mass in galaxies of low mass, those outside the red sequence, and to allow a contribution from galaxies of low mass that is clustercentric dependent. We pay special attention to issues and contributions that are usually underrated, yet are major sources of uncertainty, and we present an approach that allows us to account for all of them. Here we present the results for three very massive clusters at $z\sim0.45$, MACSJ1206.2-0847, MACSJ0329.6-0211, and RXJ1347.5-1145. We find that stellar mass and total matter are closely distributed on scales from about 150 kpc to 2.5 Mpc: the stellar-to-total mass ratio is radially constant. We find that the characteristic mass stays constant across clustercentric radii and clusters, but that the less-massive end of the galaxy mass function is dependent on the environment.

description: Le secteur de la construction s'efforce de relever les défis environnementaux actuels de diverses manières. Les blocs de terre comprimée (BTC) semblent être une alternative prometteuse. Ils permettent de réduire la consommation d'énergie tout en ayant un faible impact environnemental. En parallèle, l’utilisation de matériaux recyclés et la valorisation des déchets sont des pratiques à renforcer pour limiter la quantité de déchets produits mais aussi celle des matières premières utilisées. Chaque année, plusieurs milliers de mètres cubes de sédiments de dragage du bassin d’Arcachon sont stockés dans le but d’être valorisés. Leur utilisation pour la fabrication des BTC est alors d’un double intérêt. La problématique de la variabilité des sédiments a poussé à étudier la compatibilité de plusieurs prélèvements de différents ports du bassin avec les performances visées. De même, l’influence de plusieurs paramètres de fabrication, notamment la pression de compactage, le type et le pourcentage de stabilisation (paillis de lin, chanvre, copeaux de bois) sur la performance des blocs a été étudiée. L’augmentation de la pression de compactage statique permet d’améliorer les propriétés mécaniques et la durabilité notamment pour la résistance à la compression et à la vapeur d’eau. L’intégration de paillis de lin, de chanvre et de copeaux de bois à 0,5%, et 1% a diminué le taux de retrait et amélioré les propriétés mécaniques des blocs. De plus, une évaluation environnementale est menée pour vérifier l’aspect écologique du BTC fabriqué.

This research involves 115 students training with Mecagenius (serious game in mechanical engineering). The results of the exploratory study also confirm the relevance of the use of flow in Education scale (EduFlow) to evaluate the optimal learning experienc ewith a serious game. It also appears that EduFlow is related to specific actions within the school context such as self-efficacy, motivational climate and interest.

description: We apply the recently proposed quantum probing protocols with an unknown system-probe coupling to probe the convex coefficients in mixtures of commuting states. By using two reference states instead of one as originally suggested, we are able to probe both lower and upper bounds for the convex coefficient. We perform extensive analysis for the roles of the parameters characterizing the double peaked Gaussian frequency spectrum in the Markovian-to-non-Markovian transition of the polarization dynamics of a single photon. We apply the probing of the convex coefficient to the transition-inducing frequency parameter and show that the non-Markovianity of the polarization dynamics can be confirmed with a single snapshot measurement of the polarization qubit performed at unknown time and even with unknown coupling. We also show how the protocol can identify Markovian and non-Markovian time intervals in the dynamics. The results are validated with single photon experiments.

description: Spatial process models are widely used for modeling point-referenced variables arising from diverse scientific domains. Analyzing the resulting random surface provides deeper insights into the nature of latent dependence within the studied response. We develop Bayesian modeling and inference for rapid changes on the response surface to assess directional curvature along a given trajectory. Such trajectories or curves of rapid change, often referred to as \emph{wombling} boundaries, occur in geographic space in the form of rivers in a flood plain, roads, mountains or plateaus or other topographic features leading to high gradients on the response surface. We demonstrate fully model based Bayesian inference on directional curvature processes to analyze differential behavior in responses along wombling boundaries. We illustrate our methodology with a number of simulated experiments followed by multiple applications featuring the Boston Housing data; Meuse river data; and temperature data from the Northeastern United States.

description: Strongly-interacting artificial spin systems are moving beyond mimicking naturally-occurring materials to emerge as versatile functional platforms, from reconfigurable magnonics to neuromorphic computing. Typically artificial spin systems comprise nanomagnets with a single magnetisation texture: collinear macrospins or chiral vortices. By tuning nanoarray dimensions we achieve macrospin/vortex bistability and demonstrate a four-state metamaterial spin-system 'Artificial Spin-Vortex Ice' (ASVI). ASVI can host Ising-like macrospins with strong ice-like vertex interactions, and weakly-coupled vortices with low stray dipolar-field. Vortices and macrospins exhibit starkly-differing spin-wave spectra with analogue-style mode-amplitude control and mode-frequency shifts of df = 3.8 GHz. The enhanced bi-textural microstate space gives rise to emergent physical memory phenomena, with ratchet-like vortex training and history-dependent nonlinear fading memory when driven through global field cycles. We employ spin-wave microstate fingerprinting for rapid, scaleable readout of vortex and macrospin populations and leverage this for spin-wave reservoir computation. ASVI performs linear and non-linear mapping transformations of diverse input signals as well as chaotic time-series forecasting. Energy costs of machine learning are spiralling unsustainably, developing low-energy neuromorphic computation hardware such as ASVI is crucial to achieving a zero-carbon computational future.

description: Origin of linear instability resulting in rotating sheared accretion flows has remained a controversial subject for long. While some explanations of such non-normal transient growth of disturbances in the Rayleigh stable limit were available for magnetized accretion flows, similar instabilities in absence of magnetic perturbations remained unexplained. This dichotomy was resolved in two recent publications by Chattopadhyay, {\it et al} where it was shown that such instabilities, especially for non-magnetized accretion flows, were introduced through interaction of the inherent stochastic noise in the system (even a \enquote{cold} accretion flow at 3000K is too \enquote{hot} in the statistical parlance and is capable of inducing strong thermal modes) with the underlying Taylor-Couette flow profiles. Both studies, however, excluded the additional energy influx (or efflux) that could result from nonzero cross-correlation of a noise perturbing the velocity flow, say, with the noise that is driving the vorticity flow (or equivalently the magnetic field and magnetic vorticity flow dynamics). In this article we show that nonzero noise cross-correlations essentially renormalize the strength of temporal correlations. Apart from an overall boost in the energy rate (both for spatial and temporal correlations, and hence in the ensemble averaged energy spectra), this results in mutual competition in growth rates of affected variables often resulting in suppression of oscillating Alfven waves at small times while leading to faster saturations at relatively longer time scales. The effects are seen to be more pronounced with magnetic field fluxes where the noise cross-correlation magnifies the strength of the field concerned.

description: La liquéfaction est un phénomène dangereux observé principalement dans les sols sans cohésion, est bien documentée dans des conditions de pleine saturation. Cette étude explore le potentiel de liquéfaction du matériau de sable Hostun RF sous chargement dynamique dans un appareil triaxial. L'objectif de cette étude se concentre sur l'analyse du potentiel de liquéfaction du matériau de sable Hostun RF sous chargement dynamique dans un appareil triaxial. Trois tests, avec une contrainte effective initiale de 100 kPa, examinent l'influence de la densité du sol et du degré de saturation sur le potentiel de liquéfaction. Le premier test, présentant une densité relative de 71% et un degré de saturation de 96%, représente un échantillon relativement dense. Le deuxième test, avec une densité relative initiale de 55% et un degré de saturation de 85%, montre une liquéfaction sous des charges dynamiques contrôlées par la déformation dans des conditions non drainées. En revanche, le troisième test explore un échantillon peu saturé avec une densité relative de 55% et un degré de saturation initial de 62%, ne révélant aucune potentialité de liquéfaction même après 50 cycles de charge appliquée. Ces résultats suggèrent l'existence d'un seuil de degré de saturation pour la liquéfaction du sable, influencé à la fois par la densité relative initiale et la consolidation isotrope.

description: There is a growing use of neural network classifiers as unbinned, high-dimensional (and variable-dimensional) reweighting functions. To date, the focus has been on marginal reweighting, where a subset of features are used for reweighting while all other features are integrated over. There are some situations, though, where it is preferable to condition on auxiliary features instead of marginalizing over them. In this paper, we introduce neural conditional reweighting, which extends neural marginal reweighting to the conditional case. This approach is particularly relevant in high-energy physics experiments for reweighting detector effects conditioned on particle-level truth information. We leverage a custom loss function that not only allows us to achieve neural conditional reweighting through a single training procedure, but also yields sensible interpolation even in the presence of phase space holes. As a specific example, we apply neural conditional reweighting to the energy response of high-energy jets, which could be used to improve the modeling of physics objects in parametrized fast simulation packages.

description: The $Λ$CDM model provides a good fit to most astronomical observations but harbors large areas of phenomenology and ignorance. With the improvements in the precision and number of observations, discrepancies between key cosmological parameters of this model have emerged. Among them, the most notable tension is the 4$σ$ to 6$σ$ deviation between the Hubble constant ($H_{0}$) estimations measured by the local distance ladder and the cosmic microwave background (CMB) measurement. In this review, we revisit the $H_{0}$ tension based on the latest research and sort out evidence from solutions to this tension that might imply new physics beyond the $Λ$CDM model. The evidence leans more towards modifying the late-time universe.

Money Lending and Settling Debts in and around Meran (South Tirol) in the 14th Century
Creators: name: Köhler, Stephan
Publisher: name: Mannheim Working Papers in Premodern Economic History"
Year: 2020

description: Recent studies of credit practices in (northwestern) Europe have shown that credit markets already existed in the medieval period in the towns and countryside. Little is known, however, about how these credit markets in large parts of medieval Europe allowed a reallocation of capital and how they actually worked. Market structures that helped to limit transaction costs were usually an exponent of the social structure, for example by regulating access to the market or protecting property rights. Thus, market structures – and the development of credit markets – differed from region to region. Exploring the practices of money lending in the Alpine region of South Tirol may offer new insights into the functioning of medieval capital markets. The registers (imbreviatura) of several Tirolian notaries (particularly 1390-1392), and records of provincial courts (eleich taidings; 1388-1391) are used in this paper to describe the credit market in Meran (South Tirol) and its hinterland in the 14th century. As will be shown, several social groups ranging from nobles to urban citizens and peasants from the countryside were engaged in the credit market. The analysis of the transactions documented by the notaries and the provincial courts provides a picture of a dynamic credit market that permeated not only Meran but also small towns in the countryside like Naturns, Partschins, Lana, Algund, Forst and Riffian. To further profile the 14th century credit market in South Tirol, a comparison is made between the debts recorded by notaries and the (defaulted) debts litigated before the provincial courts. To what extent did the clientele differ (social group, place of residence)? Was there a difference in their borrowing behaviour? Moreover, what economic mechanisms were used to guarantee repayment? Besides, it will be tested whether urban centres were a prerequisite for functioning credit markets. The general picture that emerges from the study is that different credit practices and institutions (written evidence provided by notaries, pawn broking, legal courts, practice of pledging) helped different social groups to gain access to the capital market.

description: Multi-orbital Hubbard models are shown to exhibit a spatially isotropic spin-triplet superconducting phase, where equal-spin electrons in different local orbitals are paired. This superconducting state is stabilized in the spin-freezing crossover regime, where local moments emerge in the metal phase, and the pairing is substantially assisted by spin anisotropy. The phase diagram features a superconducting dome below a non-Fermi liquid metallic region and next to a magnetically ordered phase. We suggest that this type of fluctuating-moment induced superconductivity, which is not originating from fluctuations near a quantum critical point, may be realized in spin-triplet superconductors such as strontium ruthenates and uranium compounds.

Electron cyclotron drift instability and anomalous transport: two-fluid moment theory and modeling

description: In the presence of a strong electric field perpendicular to the magnetic field, the electron cross-field (E$\times$B) flow relative to the unmagnetized ions can cause the Electron Cyclotron Drift Instability (ECDI) due to resonances of the ion acoustic mode and the electron cyclotron harmonics. This occurs in collisionless shock ramps in space, and in $\rm{E \times B}$ discharge devices such as Hall thrusters. ECDI can induce an electron flow parallel to the background E field at a speed greatly exceeding predictions by classical collision theory. Such anomalous transport may lead to particle thermalization at space shocks, and may cause unfavorable plasma flows towards the walls of E$\times$B devices. The development of ECDI and anomalous transport is often considered fully-kinetic. In this work, however, we demonstrate that a reduced variant of this instability, and more importantly, the associated anomalous transport, can be treated self-consistently in a two-fluid framework without any collision. By treating electrons and ions on an equal footing, the free energy allows the growth of an anomalous electron flow parallel to the background E field. We first present linear analyses of the instability in the two-fluid 5- and 10-moment models, and compare them against the fully-kinetic theory. At lower temperatures, the two-fluid fastest-growing mode is in good agreement with the kinetic result. Also, by including more ($>=10$) moments, secondary (and possibly higher) unstable branches can be recovered. The dependence of the instability on various parameters is also explored. We then carry out direct numerical simulations of the cross-field setup using the 5-moment model. The growth of the instability and the anomalous transport is confirmed. Finally, 5-moment and Vlasov simulations using identical parameters in the lower-temperature regime are performed, showing reasonable agreement.

description: The contribution deals with the perspective of incorporating the TSCG into the legal order of the European Union, with particular attention to the proposal for a Directive presented by the European Commission on 6 December 2017, in the context of the so-called ‘Saint-Nicholas’ EMU Package. After having briefly recalled the legal nature of the TSCG, the specific provision laid down in Article 16 thereof – setting out an (alleged) obligation to take the necessary steps to incorporate the ‘substance’ of the stability treaty into the legal framework of the EU – is examined. The Commission’s proposal is then summarized and critically assessed, highlighting some problematic issues, such as the narrow scope of the envisaged integration of the TSCG, the choice of a more than questionable legal basis and the limited involvement of the European Parliament. Finally, several conclusions are drawn, on the basis of the analysis carried out.
The German Political Propaganda Postcard
Creators: name: Fraser, John
Publisher: name: London South Bank University
Year: 1978

description: This thesis sets out to establish that from the 1800's the picture postcard was an important component of popular German culture and that between 1914 and 1945 it was used as an instrument of political propaganda. The picture postcard was pioneered in Germany in the 1880's and 1890's and by 1900 a craze had developed, not only in Germany but across Europe and North America, for the sending and collecting of picture postcards. This fashion lasted for several years and was revived by the First World War but declined rapidly after the war, with the exception of a few countries - notably Germany. In Germany interest in the picture postcard continued almost unabated, the number of subjects and aspects of German life covered on the picture postcard being as varied as hitherto. One important use of the picture postcard was for political propaganda. From the 1890's patriotic postcards were common in Germany and in 1898-99 an anti-French campaign was waged on postcards over the Dreyfus affair, soon followed by an anti-British campaign over the South African War. These campaigns were characterised by the use of vigorous cartoons and caricatures, and the same quality of vituperation and vehemence reappeared on German postcards during the First World War. Postcards were also used in the war loan campaigns and to help build up wartime personalities and heroes, as well as to raise money for the war charities. The raising of money by selling postcards was taken much further by the Nazis, who also greatly extended the range of propaganda conducted on the picture postcard so that now, in retrospect, the postcards produced under the Third Reich form an almost complete pictorial history of the years 1933-45.

description: Employing first principles parallel tempering molecular dynamics in the microcanonical ensemble, we report the presence of a clear solid-liquid-like melting transition in Al20+ clusters, not found in experiments. The phase transition temperature obtained from the multiple histogram method is 993 K, 60 K above the melting point of aluminium. Root mean squared bond length fluctuation, the velocity auto-correlation function and the corresponding power spectrum further confirm the phase transition from a solid-like to liquid-like phase. Atoms-In-Molecules analysis shows a strong charge segregation between the internal and surface atoms, with negatively charged internal atoms and positive charge at the surface. Analysis of the calculated diffusion coefficient indicates different mobilities of the internal and surface atoms in the solid-like phase, and the differences between the environment of the internal atoms in these clusters with that of the bulk atoms suggest a physical picture for the origin of greater-than-bulk melting temperatures.

description: The insurance industry is shifting their sales mode from offline to online, in expectation to reach massive potential customers in the digitization era. Due to the complexity and the nature of insurance products, a cost-effective online sales solution is to exploit chatbot AI to raise customers' attention and pass those with interests to human agents for further sales. For high response and conversion rates of customers, it is crucial for the chatbot to initiate a conversation with personalized opening sentences, which are generated with user-specific topic selection and ordering. Such personalized opening sentence generation is challenging because (i) there are limited historical samples for conversation topic recommendation in online insurance sales and (ii) existing text generation schemes often fail to support customized topic ordering based on user preferences. We design POSGen, a personalized opening sentence generation scheme dedicated for online insurance sales. It transfers user embeddings learned from auxiliary online user behaviours to enhance conversation topic recommendation, and exploits a context management unit to arrange the recommended topics in user-specific ordering for opening sentence generation. POSGen is deployed on a real-world online insurance platform. It achieves 2.33x total insurance premium improvement through a two-month global test.

The assessment and management of social impacts in urban transport infrastructure projects: exploring relationships between urban governance, project management and impact assessment practices in different geographical contexts

description: Practices in the assessment and management of social impacts play an important role in the ongoing development of urban transport infrastructure megaprojects. Social Impact Assessment (SIA) is an internationally recognised process used to predict, assess and manage impacts aimed at securing an equitable distribution of social benefits and costs. However, practitioners applying SIA face significant challenges in balancing strategic policy objectives and specific project aims. The pilot study for this research suggested practitioners have limited influence on long-term social outcomes as their involvement is constrained by political decision-making and planning approval processes. Using a qualitative analysis of three rail infrastructure megaprojects from two urban geographical contexts, Sydney Australia and Amsterdam in the Netherlands, this research investigated what constrains and influences assessment and management of social impacts. It considered relationships between urban geographical context and real-world practices of Environmental and Social Impact Assessment (ESIA) and management in these cases. It asks what lessons might be drawn to improve social outcomes in the future. Primary research methods included document analysis, field observations, semi-structured interviews and international focus groups with practitioners, professionals and academics. Findings are documented as a set of publications. The thesis argues that over-emphasis of technical (financial and engineering) aspects during urban and transport planning risks decision-makers undervaluing social impacts. Public interest issues identified through public consultation and by practitioners are often overlooked in project lifecycles due to poor integration of urban governance and project management processes. It argues the implementation of good practice SIA, Follow-up, and the management of impacts, is constrained by a tension between governance priorities at multiple spatial scales. The findings suggest that adaptive management and governance to respond to social change arising from megaprojects over time is essential. The thesis concludes that practice must be supported by effective integration of impact assessments with project management, urban governance and planning to improve social outcomes from transport infrastructure megaprojects.

description: We study the renormalizability in theories of a self-interacting Lifshitz scalar field. We show that although the statement of power-counting is true at one-loop order, in generic cases where the scalar field is dimensionless, an infinite number of counter terms are involved in the renormalization procedure. This problem can be avoided by imposing symmetries, the shift symmetry in the present paper, which allow only a finite number of counter terms to appear. The symmetry requirements might have important implications for the construction of matter field sectors in the Horava-Lifshitz gravity.

description: We present a Model Uncertainty-aware Differentiable ARchiTecture Search ($μ$DARTS) that optimizes neural networks to simultaneously achieve high accuracy and low uncertainty. We introduce concrete dropout within DARTS cells and include a Monte-Carlo regularizer within the training loss to optimize the concrete dropout probabilities. A predictive variance term is introduced in the validation loss to enable searching for architecture with minimal model uncertainty. The experiments on CIFAR10, CIFAR100, SVHN, and ImageNet verify the effectiveness of $μ$DARTS in improving accuracy and reducing uncertainty compared to existing DARTS methods. Moreover, the final architecture obtained from $μ$DARTS shows higher robustness to noise at the input image and model parameters compared to the architecture obtained from existing DARTS methods.

Charge radii in covariant density functional theory: a global view

description: A systematic global investigation of differential charge radii has been performed within the CDFT framework for the first time. Theoretical results obtained with conventional covariant energy density functionals and separable pairing interaction are compared with experimental differential charge radii in the regions of the nuclear chart in which available experimental data crosses neutron shell closures at N = 28, 50, 82 and 126. The analysis of absolute differential radii of different isotopic chains and their relative properties indicate clearly that such properties are reasonably well described in model calculations in the cases when the mean-field approximation is justified. However, while the observed clusterization of differential charge radii of different isotopic chains is well described above the N=50 and N=126 shell closures, it is more difficult to reproduce it above the N=28 and N=82 shell closures because of possible deficiencies in underlying single-particle structure. The impact of the latter has been evaluated for spherical shapes and it was shown that the relative energies of the single-particle states and the patterns of their occupation with increasing neutron number have an appreciable impact on the evolution of the differential charge radii. It is shown that the kinks in the charge radii at neutron shell closures are due to the underlying single-particle structure and due to weakening or collapse of pairing at these closures. It is usually assumed that pairing is a dominant contributor to odd-even staggering (OES) in charge radii. Our analysis paints a more complicated picture. It suggests a new mechanism in which the fragmentation of the single-particle content of the ground state in odd-mass nuclei due to particle-vibration coupling provides a significant contribution to OES in charge radii.

description: Diminution of the thermal conductivity is a crucial aspect in thermoelectric research. We report a systematic and significant reduction of the cross-plane thermal conductivity in a model system consisting of DC sputtered TiNiSn and HfNiSn half-Heusler superlattices. The reduction of $κ$ is measured by the 3$ω$ method and originates from phonon scattering at the internal interfaces. Heat transport in the superlattices is calculated based on Boltzmann transport theory, including a diffusive mismatch model for the phonons at the internal interfaces. Down to superlattice periodicity of 3 nm the phonon spectrum mismatch between the superlattice components quantitatively explains the reduction of $κ$. For very thin individual layers the interface model breaks down and the artificial crystal shows an enhanced $κ$. We also present an enhanced ZT value for all investigated superlattices compared to the single TiNiSn and HfNiSn films.

description: Nonholonomic models of automobiles are developed by utilizing tools of analytical mechanics, in particular the Appellian approach that allows one to describe the vehicle dynamics with minimum number of time-dependent state variables. The models are categorized based on how they represent the wheel-ground contact, whether they incorporate the longitudinal dynamics, and whether they consider the steering dynamics. It is demonstrated that the developed models can be used to design low-complexity controllers that enable automated vehicles to execute a large variety of maneuvers with high precision.

Galois-Module Theory for Wildly Ramified Covers of Curves over Finite Fields  (with an Appendix by Bernhard K\"ock and Adriano Marmora)

description: Given a Galois cover of curves over $\mathbb{F}_p$, we relate the $p$-adic valuation of epsilon constants appearing in functional equations of Artin L-functions to an equivariant Euler characteristic. Our main theorem generalises a result of Chinburg from the tamely to the weakly ramified case. We furthermore apply Chinburg's result to obtain a `weak' relation in the general case. In the Appendix, we study, in this arbitrarily wildly ramified case, the integrality of $p$-adic valuations of epsilon constants.
