description: Aims. The metal-poor star BPM 3066 belongs to the retrograde halo and presents unexpectedly strong spectral features of lithium. To gain insight into the origin of this peculiar abundance, we investigate the chemistry and kinematic properties of this star. Methods. We performed a local thermodynamic equilibrium chemical abundance analysis of UVES/VLT high-resolution spectra of BPM 3066 using ATLAS9 and ATLAS12 model atmospheres and the MyGIsFOS code. We further characterised the orbital properties of the star by integrating its orbit and analysing its integrals of motion using the galpy code. Results. The star BPM 3066 shows an exceptional overabundance of both lithium and beryllium. The abundances are A(Li) = 3.0 and A(Be) = 2.1, which are respectively about 0.8 and 2.2 dex higher than the Li and Be abundances expected at [Fe/H] = -1.5, the metallicity of the star. The observed ratio 7Li/9Be is 7.9, which is close to that expected from a synthesis by spallation processes. Overabundances of Si, Al, and of the neutron capture elements Sr,Y, Zr, and Ba are also measured. Kinematically, BPM 3066 has an eccentric, strongly retrograde orbit, confined to a height lower than 1 kpc from the galactic plane, and it is a candidate member of the Sequoia/Thamnos accreted galaxy. Conclusions. The processes leading to the 7Li and 9Be synthesis could have occurred in the environment of a hypernova. This is supported by some abundance anomalies like the high value of Si, [Si/Fe]=1.2 and [Si/O]=1.1. However, the simultaneous high values of N, Na, Al, Sc, Ti, and Cu are at odds with the expectations from a hypernova. Alternatively, the abundances of BPM 3066 could result from the engulfing of rocky planets that were rich in spallated Li and Be. In both cases, it is remarkable that such an extreme abundance pattern has been found in a star belonging to the Sequoia/Thamnos accreted galaxy.

Does carbon tax analysis consider motivation and household level behavioural change? Evaluation based on definitions from MCT and SDT.
Creators: name: Holland, Vanessa
Publisher: name: My University
Year: 2016

description: This study seeks to examine how motivational processes derived from economic and psychological theory could explain the effect of carbon taxes on pro-environmental behavioural change. In order to achieve this goal, the following paper will outline two prominent theories, motivational crowding theory (MCT) and self-determination theory (SDT), and comment on current carbon tax analysis seeing whether or not definitions used from either field are applied in practice. Four countries and one province with established carbon taxes were selected and carbon tax analysis was scored based on a classification criterion developed from an extensive, narrative literature review. The main conclusions from this research is that few studies include or comment on individual level behavioural change following the implementation of a carbon tax, and when they do, applied definitions are more closely aligned with economics. Pro-environmental behavioural change is believed to be of crucial importance in order to combat the current environmental issues that are facing our world. For this reason, it is important that the new policies being adopted are ensuring that processes consistent with self-determined motivation (in opposition to externally regulated or controlled motivation) are being supported in order to achieve lasting behavioural change. Analyses of these policies should not only include aspects of motivation, but they should incorporate definitions and tools from both fields in order to have a more thorough approach.

description: We study singly Cabibbo-suppressed two-body hadronic decays of the charmed baryon $Λ_c^+$, namely, $Λ_c^+\to ΛK^+, pπ^0, pη, nπ^+,Σ^0K^+,Σ^+ K^0$. We use the measured rate of $Λ_c^+\to pϕ$ to fix the effective Wilson coefficient $a_2$ for naive color-suppressed modes and the effective number of color $N_c^{\rm eff}$. We rely on the current-algebra approach to evaluate $W$-exchange and nonfactorizable internal $W$-emission amplitudes, that is, the commutator terms for the $S$-wave and the pole terms for the $P$-wave. Our prediction for $Λ_c^+\to pη$ is in excellent agreement with the BESIII measurement. The $pη$ ($pπ^0$) mode has a large (small) rate because of a large constructive (destructive) interference between the factorizable and nonfactorizable amplitudes for both $S$- and $P$-waves. Some of the SU(3) relations such as $M(Λ_c^+\to nπ^+)=\sqrt{2}M(Λ_c^+\to pπ^0)$ derived under the assumption of sextet dominance are not valid for decays with factorizable terms. Our calculation indicates that the branching fraction of $Λ_c^+\to nπ^+$ is about 3.5 times larger than that of $Λ_c^+\to pπ^0$. Decay asymmetries are found to be negative for all singly Cabibbo-suppressed modes and range from $-0.56$ to $-0.96$.

description: The recent discovery of the electromagnetic counterpart of the gravitational wave source GW170817, has demonstrated the huge informative power of multi-messenger observations. During the next decade the nascent field of multi-messenger astronomy will mature significantly. Around 2030, third generation gravitational wave detectors will be roughly ten times more sensitive than the current ones. At the same time, neutrino detectors currently upgrading to multi km^3 telescopes, will include a 10 km^3 facility in the Southern hemisphere that is expected to be operational around 2030. In this review, we describe the most promising high frequency gravitational wave and neutrino sources that will be detected in the next two decades. In this context, we show the important role of the Transient High Energy Sky and Early Universe Surveyor (THESEUS), a mission concept proposed to ESA by a large international collaboration in response to the call for the Cosmic Vision Programme M5 missions. THESEUS aims at providing a substantial advancement in early Universe science as well as playing a fundamental role in multi-messenger and time-domain astrophysics, operating in strong synergy with future gravitational wave and neutrino detectors as well as major ground- and space-based telescopes. This review is an extension of the THESEUS white paper (Amati et al. 2017), also in light of the discovery of GW170817/GRB170817A that was announced on October 16th, 2017.

If the bias between the principal and the agent is large then the optimal delegation set is an interval. When the bias is small or medium the optimal delegation set is no longer connected. It can be one of two types: 1) with an interval and low option, 2) with two intervals. In all cases the agent has less discretion. However, in the case of medium bias the principal delegates in a wider range than in the case of an informed agent. / Nous considérons un problème de délégation avec un agent potentiellement mal informé lorsque le principal ne peut pas utiliser les paiements monétaires. Si l'écart entre le principal et l’agent est grande l'ensemble optimal de délégation est un intervalle. Lorsque le biais est petit ou moyenne l'ensemble optimal de délégation n'est plus connecté. Il peut s'agir de deux types: 1) avec un intervalle et l'option faible, 2) avec deux intervalles. Dans tous les cas, l'agent à moins de discrétion.

Comparison of improved TMD and CGC frameworks in forward quark dijet production

description: For studying small-$x$ gluon saturation in forward dijet production in high-energy dilute-dense collisions, the improved TMD (ITMD) factorization formula was recently proposed. In the Color Glass Condensate (CGC) framework, it represents the leading term of an expansion in inverse powers of the hard scale. It contains the leading-twist TMD factorization formula relevant for small gluon's transverse momentum $k_t$, but also incorporates an all-order resummation of kinematical twists, resulting in a proper matching to high-energy factorization at large $k_t$. In this paper, we evaluate the accuracy of the ITMD formula quantitatively, for the case of quark dijet production in high-energy proton-proton($p+p$) and proton-nucleus ($p+A$) collisions at LHC energies. We do so by comparing the quark-antiquark azimuthal angle $Δϕ$ distribution to that obtained with the CGC formula. For a dijet with each quark momentum $p_t$ much larger than the target saturation scale, $Q_s$, the ITMD formula is a good approximation to the CGC formula in a wide range of azimuthal angle. It becomes less accurate as the jet $p_t$'s are lowered, as expected, due to the presence of genuine higher-twists contributions in the CGC framework, which represent multi-body scattering effects absent in the ITMD formula. We find that, as the hard jet momenta are lowered, the accuracy of ITMD start by deteriorating at small angles, in the high-energy-factorization regime, while in the TMD regime near $Δϕ=π$, very low values of $p_t$ are needed to see differences between the CGC and the ITMD formula. In addition, the genuine twists corrections to ITMD become visible for higher values of $p_t$ in $p+A$ collisions, compared to $p+p$ collisions, signaling that they are enhanced by the target saturation scale.

For $K=0$ or $-1$, $-10$, there is an initial null big-bang singularity.

By using the Hamiltonian, we explore the picture of helical edge states in tensile and compressively strained HgTe QWs. We show that both dispersion and probability density of the edge states can differ significantly from those predicted by the Bernevig-Hughes-Zhang (BHZ) model. Our results pave the way towards further theoretical investigations of HgTe-based quantum spin Hall insulators with direct and indirect band gaps beyond the BHZ model.

description: A new approach to the choice ofeconometric estimators, called small-sigma asymptotics, is introduced and applied to the choice of k-class estimators of the parameters of a single equation in a system of linear simultaneous stochastic equations. I find that when the degree of over-identification is no more than six, the two stage least squares estimator uniformly dominates the limited information maximum likelihood estimator in a certain sense. The small sigma method can be used on many problems in statistics and econometrics.

Loi 21 : Neutre sur un terrain divisoire ? Perceptions des personnes s’exprimant sur des groupes Facebook
Creators: name: El Helou, Cassandra
Publisher: name: My University
Year: 2021

description: Les signes religieux ont souvent été source de polémiques dans les médias québécois, d’abord lors des débats sur les accommodements raisonnables et la charte des valeurs québécoises en 2007, puis tout au long du processus d’adoption de la loi 21 en juin 2019 (Mathelet, 2017; Hassan et coll. 2016). Les discours médiatiques sont caractérisés par une montée du nationalisme québécois expliqué par un contexte historique et sociopolitique unique. L’adoption de la L-21 a des répercussions considérables sur l’accès à l’emploi des personnes portant des signes religieux, mais aussi sur la société, renforçant la dichotomie déjà bien ancrée entre les « autres » et le « nous », et ce, au profit des personnes les plus privilégiées. Ce mémoire cherche donc à mettre en lumière les effets de cette loi sur la vie des personnes ciblées en analysant leurs perceptions à travers des publications et commentaires faits sur des groupes Facebook. Peu de recherches se sont attardées sur les opinions des personnes directement visées par la L-21, rendant d’autant plus pertinent notre mémoire souhaitant visibiliser les propos rapportés par les princip.ales.aux concerné.e.s. Se concentrant davantage sur les réalités des femmes musulmanes, c’est avec une posture féministe décoloniale et intersectionnelle que nous avons tenté une analyse des barrières structurelles auxquelles elles sont principalement confrontées. Finalement, à la suite d’une collecte de données composée de commentaires et de publications recensées sur les groupes Facebook s’opposant à la L-21, nous avons fait une analyse qualitative thématique utilisant le logiciel Nvivo et son extension Ncapture. Nos résultats nous ont permis de mieux comprendre les effets de la L-21 en termes d’attitude, des perceptions envers le gouvernement, de la laïcité, des discriminations, du racisme, du sexisme et de la haine anti-musulman vécus depuis le début du processus d’adoption de la L-21. Ainsi, les propos des personnes s’exprimant sur des groupes Facebook publics serviront d’élément central pour mieux comprendre les effets de la loi 21.
Classification of Machine Learning Frameworks for Data-Driven Thermal Fluid Models

description: Thermal fluid processes are inherently multi-physics and multi-scale, involving mass-momentum-energy transport phenomena. Thermal fluid simulation (TFS) is based on solving conservative equations, for which - except for "first-principle" direct numerical simulation - closure relations (CRs) are required to provide microscopic interactions. In practice, TFS is realized through reduced-order modeling, and its CRs can be informed by observations and data from relevant and adequately evaluated experiments and high-fidelity simulations. This paper focuses on data-driven TFS models, specifically on the development using machine learning (ML). Five ML frameworks, dubbed Type I to V, are introduced. The frameworks vary in their performance for different applications depending on the level of knowledge of governing physics, the source, type, amount and quality of available data for training. Notably, outlined for the first time in this paper, Type III models present stringent requirements on modeling, substantial computing resources for training, and high potential in extracting value from "big data" in thermal fluid research. The paper demonstrates the ML frameworks by three examples. First, we utilize the heat diffusion equation with nonlinear conductivity formulated by convolutional neural networks to illustrate the applications of Type I, II, and III ML. The results indicate a preference for Type II ML under deficient data support. Type III ML can effectively utilize field data, potentially generating more robust predictions than Type I and II ML. Second, we illustrate how to employ Type I ML and Type II ML frameworks for data-driven turbulence modeling using reference works. Third, we demonstrate Type I ML by building a deep learning (DL)-based slip closure for two-phase flow modeling. The results showe that the DL-based closure exhibits a bounded error in prediction domain.

description: We discuss several features of coherent choice functions - where the admissible options in a decision problem are exactly those which maximize expected utility for some probability/utility pair in fixed set S of probability/utility pairs. In this paper we consider, primarily, normal form decision problems under uncertainty - where only the probability component of S is indeterminate. Coherent choice distinguishes between each pair of sets of probabilities. We axiomatize the theory of choice functions and show these axioms are necessary for coherence. The axioms are sufficient for coherence using a set of probability/almost-state-independent utility pairs. We give sufficient conditions when a choice function satisfying our axioms is represented by a set of probability/state-independent utility pairs with a common utility.

description: The original Kerker effect was introduced for a hypothetical magnetic sphere, and initially it did not attract much attention due to a lack of magnetic materials required. Rejuvenated by the recent explosive development of the field of metamaterials and especially its core concept of optically-induced artificial magnetism, the Kerker effect has gained an unprecedented impetus and rapidly pervaded different branches of nanophotonics. At the same time, the concept behind the effect itself has also been significantly expanded and generalized. Here we review the physics and various manifestations of the generalized Kerker effects, including the progress in the emerging field of meta-optics that focuses on interferences of electromagnetic multipoles of different orders and origins. We discuss not only the scattering by individual particles and particle clusters, but also the manipulation of reflection, transmission, diffraction, and absorption for metalattices and metasurfaces, revealing how various optical phenomena observed recently are all ubiquitously related to the Kerker's concept.

description: In the light of the recently proposed scenario of asymmetry-induced synchronization (AISync), in which dynamical uniformity and consensus in a distributed system would demand certain asymmetries in the underlying network, we investigate here the influence of some regularities in the interlayer connection patterns on the synchronization properties of multilayer random networks. More specifically, by considering a Stuart-Landau model of complex oscillators with random frequencies, we report for multilayer networks a dynamical behavior that could be also classified as a manifestation of AISync. We show, namely, that the presence of certain symmetries in the interlayer connection pattern tends to diminish the synchronization capability of the whole network or, in other words, asymmetries in the interlayer connections would enhance synchronization in such structured networks. Our results might help the understanding not only of the AISync mechanism itself, but also its possible role in the determination of the interlayer connection pattern of multilayer and other structured networks with optimal synchronization properties.

description: We present a model for current-driven motion of a magnetic domain-wall line, in which the dynamics of the domain wall is equivalent to that of an overdamped vortex line in an anisotropic pinning potential. This potential has both extrinsic contributions due to, e.g., sample inhomogeneities, and an intrinsic contribution due to magnetic anisotropy. We obtain results for the domain-wall velocity as a function of current for various regimes of pinning. In particular, we find that the exponent characterizing the creep regime depends strongly on the presence of a dissipative spin transfer torque. We discuss our results in the light of recent experiments on current-driven domain-wall creep in ferromagnetic semiconductors, and suggest further experiments to corroborate our model.

description: Retrieval of episodic memory is a dynamical process in the large scale brain networks. In social groups, the neural patterns, associated to specific events directly experienced by single members, are encoded, recalled and shared by all participants. Here we construct and study the dynamical model for the formation and maintaining of episodic memory in small ensembles of interacting brains. We prove that the unconventional dynamical attractor of this process - the nonsmooth heteroclinic torus - is structurally stable within the Lotka-Volterra-like sets of equations. Dynamics on this torus combines absence of chaos with asymptotic instability of every separate trajectory; its adequate quantitative characteristics are length-related Lyapunov exponents. Variation of the coupling strength between the participants results in different types of sequential switching between metastable states; we interpret them as stages in formation and modification of the episodic memory.

description: The highly stratified nature of Mediterranean cities, if on the one hand contrib­utes to the construction of an image with remarkable historical and artistic val­ues, on the other it makes their reading and understanding more complex. The relationship between archaeology and the context, especially urban, has many variables and problems related both to the mode of use of the user/citizen as well as the need for transformation and growth of the city itself. Archaeological heritage is not a sort of “reserve” that is separated from the context. On the contrary, it is necessary to work to reduce the gap that often exists between everyday reality and the reality of the asset, the result of years of isolation policies. This contribution, from the research-project experiences matured by the author, proposes an hypothesis of “enriched” path in which cultural heritage, in particu­lar archaeological, are put to system with the context of belonging. The sustainable use of cultural resources and the concept of “selecting” the most significant goods in relation to the path to be realized, are the main ideas of the proposed considerations as well as Accessibility, comfort and safety concepts of the visit are the strategic points of a fruition project to be devel­oped starting from the user’s needs and in com­pliance with the environmental and technological compatibility of the asset to be protected.

description: Este trabajo de investigación aborda el acoso laboral como factor de riesgo psicosocial generador de problemas en la salud e integridad de los trabajadores y la responsabilidad del empleador en su calidad de garante de los derechos de aquellos cuando se presentan estas conductas y no se llevan a cabo las medidas de prevención pertinentes, generando el deterioro de la salud de los trabajadores. Para ello, se desarrolla la definición y el alcance del concepto de acoso laboral, se hace referencia a su incremento con las nuevas dinámicas laborales. Asimismo, se hace alusión a regulaciones normativas de la OIT, legislaciones internacionales y a nuestro ordenamiento. Se estudian las normas y la jurisprudencia de las obligaciones y responsabilidades del empleador, en relación a la culpa patronal, en la ocurrencia de problemas de salud en trabajadores por conductas de acoso laboral. Se concluye en una falta de regulación normativa eficiente y las consecuencias en nuestro ordenamiento jurídico, pero con la ventaja de que la jurisprudencia que aborda el tema suple a la misma, frente a un fenómeno que se encuentra en crecimiento ante las nuevas dinámicas laborales.
description: This research addresses workplace harassment as a psychosocial risk factor that generates problems in the health and integrity of workers and the responsibility of the employer as guarantor of the rights of those when these behaviors occur and the relevant preventive measures are not carried out, generating the deterioration of the workers’ health. For this purpose, the definition and scope of the concept of labor harassment is developed, referencing its increase with the new labor dynamics. Likewise, reference is made to normative regulations of the ILO, international legislations, and our legal system. The norms and jurisprudence of the employer's obligations and responsibilities are studied, in relation to the employer's fault, in the occurrence of health problems in workers due to harassment at work. It is concluded that there is a lack of efficient normative regulation and the consequences in our legal system, but with the advantage that the jurisprudence that addresses the issue supplements it, regarding a phenomenon that is growing in the face of the new labor dynamics.

description: Consider an infinite tree with random degrees, i.i.d. over the sites, with a prescribed probability distribution with generating function G(s). We consider the following variation of Renyi's parking problem, alternatively called blocking RSA: at every vertex of the tree a particle (or car) arrives with rate one. The particle sticks to the vertex whenever the vertex and all of its nearest neighbors are not occupied yet. We provide an explicit expression for the so-called parking constant in terms of the generating function.

Coupled spin and electron-phonon dynamics at the relativistic Tl/Si(111) surface

description: We investigate the role played by the electron spin and the spin-orbit interaction on the exceptional electronphonon coupling at the Tl/Si(111) surface. Our first-principles calculations demonstrate that the particular spin pattern of this system dominates the whole low-energy electron-phonon physics, which is remarkably explained by forbidden spin-spin scattering channels. In particular, we show that the strength of the electron-phonon coupling appears drastically weakened for surface states close to the K and K' valleys, which is unambiguously attributed to the spin polarization through the associated modulation due to the spinor overlaps. However, close to the Γ point, the particular spin pattern in this area is less effective in damping the electron-phonon matrix elements, and the result is an exceptional strength of electron-phonon coupling parameter λ ~ 1.4. These results are rationalized by a simple model for the electron-phonon matrix elements including the spinor terms.

Improving Accuracy of Electrochemical Capacitance and Solvation Energetics in First-Principles Calculations

description: Reliable first-principles calculations of electrochemical processes require accurate prediction of the interfacial capacitance, a challenge for current computationally-efficient continuum solvation methodologies. We develop a model for the double layer of a metallic electrode that reproduces the features of the experimental capacitance of Ag(100) in a non-adsorbing, aqueous electrolyte, including a broad hump in the capacitance near the Potential of Zero Charge (PZC), and a dip in the capacitance under conditions of low ionic strength. Using this model, we identify the necessary characteristics of a solvation model suitable for first-principles electrochemistry of metal surfaces in non-adsorbing, aqueous electrolytes: dielectric and ionic nonlinearity, and a dielectric-only region at the interface. The dielectric nonlinearity, caused by the saturation of dipole rotational response in water, creates the capacitance hump, while ionic nonlinearity, caused by the compactness of the diffuse layer, generates the capacitance dip seen at low ionic strength. We show that none of the previously developed solvation models simultaneously meet all these criteria. We design the Nonlinear Electrochemical Soft-Sphere solvation model (NESS) which both captures the capacitance features observed experimentally, and serves as a general-purpose continuum solvation model.

description: Two time series are considered in this paper: one is the volume of hard disk activity, aggregated into half-hour periods, measured on a workstation, and the other is the volume of internet requests made to a workstation. Both of these time series exhibit features typical of network traffic data, namely, strong seasonal components and highly non-Gaussian distributions. For these time series, a particular class of nonlinear state-space models is proposed, and practical techniques for model-fitting and forecasting are demonstrated.

description: The harvesting of ambient radio-frequency (RF) energy is an attractive and clean way to realize the idea of self-powered electronics. Here we present a design for a microwave energy harvester based on a nanoscale spintronic diode (NSD). This diode contains a magnetic tunnel junction with a canted magnetization of the free layer, and can convert RF energy over the frequency range from 100 MHz to 1.2 GHz into DC electric voltage. An attractive property of the developed NSD is the generation of an almost constant DC voltage in a wide range of frequencies of the external RF signals. We further show that the developed NSD provides sufficient DC voltage to power a low-power nanodevice - a black phosphorus photo-sensor. Our results demonstrate that the developed NSD could pave the way for using spintronic detectors as building blocks for self-powered nano-systems, such as implantable biomedical devices, wireless sensors, and portable electronics.

Le rôle du soutien social dans la réduction des contraintes familiales et sociales chez les proches aidants de maladies cardiovasculaires et de cancer.
Creators: name: Bah, Rougui

description: Les maladies cardiovasculaires (MCV) et le cancer ont un impact important sur les sphères émotionnelles et psycho-physiques des proches aidants. En 2018, environ un Canadien sur quatre âgé de 15 ans et plus a prodigué des soins à un membre de leur famille ou à un ami souffrant d'un problème de santé à long terme, d'une incapacité physique ou mentale ou des problèmes liés au vieillissement (Statistique Canada, 2018). Bien que certaines recherches comparent la qualité de vie des proches aidants de maladie cardiovasculaire et de cancer, peu d’études analysent la condition médicale un proche aidant est prodigué à administrer des soins et l’impact que cela peut avoir sur les relations sociales et familiales, ainsi que l’importance, en soi, d’avoir un réseau de support pour alléger le poids des responsabilités. L'étude actuelle a révélé que les proches aidants de maladies cardiovasculaires étaient plus susceptibles de subir des contraintes sociales et familiales que les proches aidants de cancer. Notamment, les résultats démontrent que le soutien social joue un rôle crucial sur les contraintes subies. C’est pourquoi il est important de prendre conscience des lacunes des systèmes mis en place pour les proches aidants lorsqu’il s’agit de soins non institutionnalisés afin d’introduire des politiques et des services qui seront mieux en mesure de les soutenir.
