description: Extensive Monte Carlo simulations are performed on a two-dimensional random field Ising model. The purpose of the present work is to study the disorder-induced changes in the properties of disordered spin systems. The time evolution of the domain growth, the order parameter and spin-spin correlation functions are studied in the non equilibrium regime. The dynamical evolution of the order parameter and the domain growth shows a power law scaling with disorder-dependent exponents. It is observed that, except for very small random fields, exchange interaction never wins over pinning interaction to establish long range order.

description: Various applications ranging from spintronic devices, giant magnetoresistance sensors, and magnetic storage devices, include magnetic parts on very different length scales. Since the consideration of the Landau-Lifshitz-Gilbert equation (LLG) constrains the maximum element size to the exchange length within the media, it is numerically not attractive to simulate macroscopic parts with this approach. On the other hand, the magnetostatic Maxwell equations do not constrain the element size, but cannot describe the short-range exchange interaction accurately. A combination of both methods allows to describe magnetic domains within the micromagnetic regime by use of LLG and also considers the macroscopic parts by a non-linear material law using the Maxwell equations. In our work, we prove that under certain assumptions on the non-linear material law, this multiscale version of LLG admits weak solutions. Our proof is constructive in the sense that we provide a linear-implicit numerical integrator for the multiscale model such that the numerically computable finite element solutions admit weak $H^1$-convergence (at least for a subsequence) towards a weak solution.

description: We explore the four dimensional Einstein-Maxwell landscape as a toy model in which we can formulate a sphere compactification stabilized by an electromagnetic field. Replacing the compactification sphere by J spheres, we obtain a simple sector of the (2J+2)-dimensional Einstein-Maxwell landscape. In this toy model, we analyze some properties which are very difficult to uncover in the string theory landscape, including: complete moduli stabilization, stability conditions, and state counting. We also show how to construct anthropic states in this model. A detailed comparison between the main features of this landscape and the Bousso-Polchinski landscape is given. We finally speculate on the impact of these phenomena in the string theory landscape.

description: This project aims to investigate the associations between climate change emotions and individual mental health and wellbeing among young adults aged between 18-24 in Ireland. We aim to investigate whether climate change experiences and/or climate change awareness evoke different climate emotions, and seek to explore potential relationships between these emotions while controlling for socio-demographics. The study also aims to investigate whether the impact of climate emotions on mental health is mediated and/or moderated by coping and pro-environmental behaviour. Additionally, we will collect qualitative data to gain a broader understanding of the impact of climate change on young adult's mental health.

description: A toy landscape sector is introduced as a compactification of the Einstein-Maxwell model on a product of two-spheres. Features of the model include: moduli stabilization, a distribution of the effective cosmological constant of the dimensionally reduced 1+1 spacetime, which is different from the analogous distribution of the Bousso-Polchinski landscape, and the absence of the so-called "alpha-star"-problem. This problem arises when the Kachru-Kallosh-Linde-Trivedi stabilization mechanism is naively applied to the states of the Bousso-Polchinski landscape. The model also contains anthropic states, which can be readily constructed without needing any fine-tuning.

description: Zur Untersuchung von Bodenverdichtungen stehen punktuell sowie großflächig anwendbare Messmethoden zur Verfügung. Als punktuelle Methoden sind vor allem Stechzylindermessungen zu nennen, bei den großflächig anwendbaren Methoden das Horizontalpenetrometer. Stechzylindermessungen sind arbeits- und kostenaufwändig und reagieren auf Veränderungen der Bodenstruktur nur mittelmäßig sensibel mit einer hohen Streuung. Das Penetrometer ist großflächig, aber nicht auf bewachsenen Flächen einsetzbar. Zudem bereiten steinige Böden Probleme. Optimal wäre also eine zerstörungsfrei arbeitende, großflächig anwendbare Messmethode, die empfindlich auf Bodenveränderungen reagiert. Als solche soll die Eignung der Geoelektrik untersucht werden.

description: We study the irreducible constituents of the reduction modulo p of irreducible algebraic representations V of Res_{K/Q_p} GL_2 for K a finite extension of Q_p. We show that asymptotically, the multiplicity of each constituent depends only on the dimension of V and the central character of its reduction modulo p. As an application, we compute the asymptotic value of multiplicities that are the object of the Breuil-Mézard conjecture.

description: Albania has one of the world's highest emigration rates, relative to its population, at -3.3 migrants per 1,000 people, and a total migrant population of more than 1.25 million in 2014, according to UN Department of Economic and Social Affairs data. In 2010 Albania was granted with visa-free travel to the Schengen area and this also affected the crossing of the borders and the circular migration across the land border between Greece and Albania was for many years, one of the most significant irregular migratory flows across the EU's external borders. Although during the last years it is observed an increase number of return migrants, Albanian citizens continued to migrate and it is observed an increase of the number during 2014, and the new trend now is requesting asylum in EU member states increased during 2014. According to EUROSTAT data show that 65,000 Albanians applied for asylum in 2015, 55,000 of them sought asylum in Germany, 99% of these asylum requests have been refused from European countries, and 1/2 of them belong to the age group 18–34 years old. Due to the poor economic and living conditions in Albania, the labor market affects the on-going migrant flows from Albania to the most developed labor markets of European countries. Migration in Albania has major development impact and poverty implications in several aspects. It affects individuals and their families, of origin and destination countries, and the national economy. At the individual level it shows that migrants benefit economically from their movements, their migration leads to better employment opportunities and income; at the household level in the home country migration reduces poverty at the family level and positively contributes to human capital formation, and improving education and healthcare conditions.

Gebräunte Haut als Schönheitsideal

description: In den westlichen Industrienationen gilt gebräunte Haut allgemein als schön und erstrebenswert. Psychologische Studien zeigen, dass Jugendliche und Erwachsene sich häufig natürlicher und künstlicher ultravioletten (UV-) Strahlung (etwa Sonnenbaden oder Solariennutzung) aussetzen, um ihre Attraktivität zu steigern. Ein solches Schönheitsideal birgt jedoch zahlreiche dermatologische und onkologische Risiken (z. B. vorzeitige Hautalterung, Hautkrebs). Im Rahmen des bundesweit repräsentativen Nationalen Krebshilfe-Monitorings (NCAM) wurden im Jahr 2017 3.000 Personen zu den sogenannten attraktivitätsbezogenen Motiven des Bräunungsverhaltens (ABM) befragt. Es zeigte sich, dass ABM eher für Befragte zwischen 18 und 35 Jahren, Befragte mit Migrationshintergrund, Befragte mit mittlerem Bildungsniveau und für Befragte ohne festen Partner relevant waren. Zudem zeigte sich, dass Personen, die sich mit dem Ziel der Attraktivitätssteigerung bräunen, eine geringere Risikowahrnehmung für natürliche und künstliche UV-Strahlung besitzen, aber gleichzeitig ein risikoreicheres Bräunungsverhalten zeigen: Sie bräunen sich häufiger im Solarium und in der Sonne und berichten dabei häufiger von einem Sonnenbrand. Damit haben diese Personen ein erhöhtes Risiko, Hautkrebs zu entwickeln. Diese Ergebnisse sind von Bedeutung für zukünftige Präventionsmaßnahmen. So sollten Präventionskampagnen auch einen Schwerpunkt auf die Reduzierung der positiven Bewertung einer gebräunten Haut und damit auf die Veränderung westlicher Schönheitsideale legen.

description: The current deliverable D13.3 gives an overview of some important methods of pattern transfer in semiconductor nanofabrication where all 4 partners, LUND, EPFL, CSIC and C2N-CNRS are involved. The emphasis is put on atomic layer etching (ALE) that represent one of few approached in nano-processing that offer a potential of atomic layer control during removal of material. A related method of layer-by-layer epitaxial growth is added to give a more complete picture. Finally, lithographic-based approaches of high-resolution patterning that do not yet provide atomic resolution are mentioned, too.

description: In the mid eighties Goldman proved an embedded curve could be isotoped to not intersect a closed geodesic if and only if their Lie bracket (as defined in that work) vanished. Goldman asked for a topological proof and about extensions of the conclusion to curves with self-intersection. Turaev, in the late eighties, asked about characterizing simple closed curves algebraically, in terms of the same Lie structure. We show how the Goldman bracket answers these questions for all finite type surfaces. In fact we count self-intersection numbers and mutual intersection numbers for all finite type orientable orbifolds in terms of a new Lie bracket operation, extending Goldman's. The arguments are purely topological, or based on elementary ideas from hyperbolic geometry. These results are intended to be used to recognize hyperbolic and Seifert vertices and the gluing graph in the geometrization of three manifolds. The recognition is based on the structure of the String Topology bracket of three manifolds.

We find a characterization of the spectrum of the resulting operator $H$ in terms of the relation between $B$ and $V$ at infinity. In particular, we give a sharp condition for the discreteness of the spectrum of $H$ beyond which we find dense pure point spectrum.

description: Let $X= \mathbb{P}^1 \setminus \{0,1,\infty\}$, and let $S$ denote a finite set of prime numbers. In an article of 2005, Minhyong Kim gave a new proof of Siegel's theorem for $X$: the set $X(\mathbb{Z}[S^{-1}])$ of $S$-integral points of $X$ is finite. The proof relies on a `nonabelian' version of the classical Chabauty method. At its heart is a modular interpretation of unipotent $p$-adic Hodge theory, given by a tower of morphisms $h_n$ between certain $\mathbb{Q}_p$-varieties. We set out to obtain a better understanding of $h_2$. Its mysterious piece is a polynomial in $2|S|$ variables. Our main theorem states that this polynomial is quadratic, and gives a procedure for writing its coefficients in terms of $p$-adic logarithms and dilogarithms.

description: This study examines remote work and the impact that Covid-19 has had on employees. The study focuses on the impact of Covid-19 on employees by analyzing the emotional experiences, feelings they have about Covid-19, productivity at work, performance, motivation, working conditions and job satisfaction. The questionnaire is the instrument used. The questionnaire was completed online in google form by 250 employees, namely 187 girls/women and 63 boys/men. The study showed that remote work has not had a direct or negative impact on employees, but has come as an innovation in all public or private organizations, a practice that has its positive and negative sides. Emotional experiences and feelings about Covid 19 are present and although faded, some employees have more pronounced these experiences compared to others. Covid 19 has affected the lives of employees but has not had a negative impact on their productivity at work. The work process has been efficient even though they have been working remotely during the biggest period of the outbreak of the pandemic. Keywords: Covid-19, employees, productivity, motivation, work.

Conditions for uniqueness of product representations for separable quantum channels and separable quantum states
Creators: name: Cohen, Scott M.
Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We give a sufficient condition that an operator sum representation of a separable quantum channel in terms of product operators is the unique product representation for that channel, and then provide examples of such channels for any number of parties. This result has implications for efforts to determine whether or not a given separable channel can be exactly implemented by local operations and classical communication. By the Choi-Jamiolkowski isomorphism, it also translates to a condition for the uniqueness of product state ensembles representing a given quantum state. These ideas follow from considerations concerning whether or not a subspace spanned by a given set of product operators contains at least one additional product operator.
description: Latest version has a new title, and is completely reorganized to emphasize the quantum information applications as opposed to the mathematical results. Version 3 has revised results for more than two parties, having discovered an error in earlier versions (see Conclusions for an explanation). Bipartite results are unchanged

description: The precise origin of short gamma ray bursts (SGRBs) remains an important open question in relativistic astrophysics. Increasingly, observational evidence suggests the merger of a binary compact object system as the source for most SGRBs, but it is currently unclear how to distinguish observationally between a binary neutron star progenitor and a black hole-neutron star progenitor. We suggest the quasi-periodic signal of jet precession as an observational signature of SGRBs originating in mixed binary systems, and quantify both the fraction of mixed binaries capable of producing SGRBs, and the distributions of precession amplitudes and periods. The difficulty inherent in disrupting a neutron star outside the horizon of a stellar-mass black hole biases the jet precession signal towards low amplitude and high frequency. Precession periods of ~ 0.01-0.1 s and disk-BH spin misalignments ~10 degrees are generally expected, although sufficiently high viscosity may prevent the accumulation of multiple precession periods during the SGRB. The precessing jet will naturally cover a larger solid angle in the sky than would standard SGRB jets, enhancing observability for both prompt emission and optical afterglows.

Changing Strategies of Mexican Drug Trafficking Organizations (DTOs) in the Context of Synthetic Opioids

description: This thesis examines the relationship between the United States demand for illicit substances and the evolution of Mexican drug trafficking organizations (DTOs), specifically within the context of a shift from heroin to synthetic opioids. A history of these interdependent actors provides a contextual understanding of Mexico’s current criminal landscape, where DTOs employ adaptive strategies to account for shifts in supply and demand. I also examine the distinctions between the supply chains for heroin and those for synthetic opioids, interpreting the possible implications for DTO strategies. Then, I conduct a regression analysis using a carefully curated set of violent event data from the Armed Conflict Location & Event Data Project (ACLED) to test whether the shift from heroin production to synthetic opioid production by DTOs led to a parallel shift in their presence and violence. My findings challenge the initial hypothesis that a decreasing rate of violence in heroin-producing regions is associated with an increasing rate of violence in Mexico’s Pacific ports - the primary node in the synthetic opioid supply chain. Further examination of the data provides valuable detail on the actions and strategies of Mexican DTOs from 2018 to the present day. I conclude by discussing the potential of event data to aid political violence research and explore possible policy solutions for both the U.S. opioid epidemic and drug violence in Mexico.

description: Cet article vise à évaluer l'impact des innovations technologiques, des réformes administratives et de l'efficacité des ressources sur la collecte des recettes douanières à la DGDA, en se concentrant sur la région du Katanga. Pour cela, une méthodologie non paramétrique a été utilisée, incluant l'indice de Malmquist et l'analyse en enveloppement des données (DEA), afin de mesurer les variations de productivité douanière sur une période donnée, en s'appuyant sur des données secondaires de la DGDA.

Les résultats révèlent que l'adoption de technologies modernes est cruciale pour optimiser les recettes douanières, avec des hausses de productivité notables en 2021. Cependant, des baisses de performance ont été observées en 2017, attribuées à un manque d'investissement technologique. L'efficacité technique est restée constante, indiquant une bonne gestion des ressources internes, mais une amélioration des outils et infrastructures est nécessaire. L'étude souligne que la modernisation technologique et les réformes institutionnelles sont essentielles pour maximiser les recettes douanières et recommande une stratégie continue d'innovation et de renforcement des capacités des agents pour améliorer les processus douaniers tout en réduisant les coûts opérationnels.

description: Après un an d’épidémie de coronavirus, la Côte d’Ivoire termine une troisième vague de Covid-19. Si l’épidémie a été confinée majoritairement dans le Grand Abidjan, notamment grâce aux mesures d’isolement imposée à la capitale économique ivoirienne, l’impact de la crise sanitaire a été néanmoins marqué. À l’instar d’autres pays d’Afrique de l’ouest, la Côte d’Ivoire n’a pas connu le tsunami épidémique que certains prévoyaient en mars 2020, mais plus de 45 000 cas et près de 300 décès ont été notifiés, tout en sachant que ces chiffres sous-estiment la réalité épidémiologique. Avec l’arrivée de la vaccination, la Côte d’Ivoire espère pouvoir contrôler l’épidémie mais la possible circulation de variants notamment sud-africains et les difficultés d’approvisionnement en doses vaccinales sont autant de défis que devront relever les autorités sanitaires ivoiriennes. La résilience des populations a été importante durant cette crise, illustrant la capacité des Ivoiriens à résister à l’impact de cette crise.

description: Inspired by Chern-Simons effective theory description of symmetry protected topological (SPT) phases in two dimensions, we present a projective construction for many-body wavefunctions of SPT phases. Using this projective construction we can systematically write down trial wavefunctions of SPT phases on a lattice. An explicit example of SPT phase with $U(1)$ symmetry is constructed for two types of bosons with filling $ν_{b_1}=ν_{b_2}=\frac12$ per site on square lattice. We study continuous phase transitions between different $U(1)$-SPT phases based on projective construction. The effective theory around the critical point is emergent $QED_3$ with fermion number $N_f=2$. Such a continuous phase transition however needs fine tuning, and in general there are intermediate phases between different $U(1)$-SPT phases. We show that such an intermediate phase has the same response as an anyon superconductor, and hence dub it "anyon superfluid". A schematic phase diagram of interacting bosons with $U(1)$ symmetry is depicted.

description: The use of Machine Learning recently, has shown an increase in performance in relation to problems in various fields. This work aims to demonstrate the importance of integrating machine learning algorithms into problem-solving solutions. The main focus is to analyze and describe the contribution of algorithms that fall under the classification tasks in this field. The concepts, processes, algorithms, and their characteristics, as well as ML techniques, mainly supervised learning techniques and other elements are discussed. Through a practical example, the main steps of building a classification algorithm using the SVM machine learning method are presented by analyzing the components needed to configure the model based on the type of data we want to classify and the parameters of the model itself.

description: Finite gauge transformations in double field theory can be defined by the exponential of generalized Lie derivatives. We interpret these transformations as `generalized coordinate transformations' in the doubled space by proposing and testing a formula that writes large transformations in terms of derivatives of the coordinate maps. Successive generalized coordinate transformations give a generalized coordinate transformation that differs from the direct composition of the original two. Instead, it is constructed using the Courant bracket. These transformations form a group when acting on fields but, intriguingly, do not associate when acting on coordinates.

description: Let V be a projective hypersurface of fixed degree and dimension which has only isolated singular points. We show that, if the sum of the Milnor numbers at the singular points of V is large, then V cannot have a point of large multiplicity, unless V is a cone. As an application, we give an affirmative answer to a conjecture of Dimca and Papadima.

description: L’impact de la COVID-19 sur le continent africain a été et reste l’une des grandes inquiétudes quant aux conséquences de la pandémie. Pourtant, loin de rester passives, les mutuelles de santé ont mis en place dès le printemps 2020 une série d’actions de sensibilisation, de soutien aux populations ainsi que de soutien à l’action de leurs gouvernements. Ces actions ont pu capitaliser sur les atouts des mutuelles : un déploiement local auprès des communautés et des catégories socioprofessionnelles, mais aussi auprès des mutualistes et des personnels de centres de soins. L’action des mutuelles auprès des populations a permis de faire l’inventaire de leurs qualités, qui seront importantes dans le cadre d’une sortie équilibrée de la crise socioéconomique à venir, le vrai défi qui attend l’Afrique.

description: (1) Background. (1) In the majority of professional fields, extended working hours are recognized as a significant contributing factor to the development of occupational burnout and the presence of psychological concerns. While prolonged working hours pose a risk, gender differences have been observed in the perceived symptoms of burnout and the experience of psychological symptoms. (2) Objective: This study aims to assess the association between working hours and the development of burnout symptoms. Additionally, it explores gender differences and examines the impact of early maladaptive schemas on burnout development. (3) Method: A total of 200 professionals participated in the study and completed three assessment tools: The Burnout Assessment Tool (BAT), the Perceived Stress Scale (PSS-10), and the Symptom Checklist-90 (SCL90). The Young Schema Questionnaire-Short Form (YSQSF) was also administered to evaluate early maladaptive schemas. (4) Results: Female participants displayed higher scores in burnout and its components, as well as in psychological symptoms. However, no gender differences were observed in early maladaptive schemas or in the development of burnout. (5) Conclusions: Within the same professional environments, female professionals may be more susceptible to developing burnout symptoms when exposed to extended working hours. The implementation of training strategies aimed at addressing occupational burnout may contribute to mitigating its impact. Keywords: perceived distress; burnout; early maladaptive schemas

Unified Field Equations Coupling Four Forces and Principle of Interaction Dynamics

description: The main objective of this article is to postulate a principle of interaction dynamics (PID) and to derive unified field equations coupling the four fundamental interactions based on first principles. PID is a least action principle subject to div$_A$-free constraints for the variational element with $A$ being gauge potentials. The Lagrangian action is uniquely determined by 1) the principle of general relativity, 2) the $U(1)$, $SU(2)$ and $SU(3)$ gauge invariances, 3) the Lorentz invariance, and 4) principle of principle of representation invariance (PRI), introduced in [11]. The unified field equations are then derived using PID. The unified field model spontaneously breaks the gauge symmetries, and gives rise to a new mechanism for energy and mass generation. The unified field model introduces a natural duality between the mediators and their dual mediators, and can be easily decoupled to study each individual interaction when other interactions are negligible. The unified field model, together with PRI and PID applied to individual interactions, provides clear explanations and solutions to a number of outstanding challenges in physics and cosmology, including e.g. the dark energy and dark matter phenomena, the quark confinement, asymptotic freedom, short-range nature of both strong and weak interactions, decay mechanism of sub-atomic particles, baryon asymmetry, and the solar neutrino problem.

EIT phenomenon for the three-level hydrogen atoms and its application to the era of the cosmological recombination

description: The electromagnetically induced transparency (EIT) phenomenon in earlier universe is considered. We evaluated the elementary processes of the single scattering of photon on the hydrogen atom with the purpose of their use in the tasks of the radiation transfer theory. The additional function $f$, which depends on external conditions, is found. This function can be considered as an adjustment of the optical depth that leads to the necessity of modernization of the escape probability $p_{ij}(τ_S)\rightarrow p_{ij}(τ_S(1+f))$. The numerical values of $f$ for the different schemes of atom in three-level approximation are given. It is found that the magnitude of function $f$ could influence significantly on the formation of CMB in some partial cases.

description: We propose a quantum optical implementation of a class of dissipative spin systems, including the XXZ and Ising model, with ultra-cold atoms in optical lattices. Employing the motional degree of freedom of the atoms and detuned Raman transitions we show how to obtain engineerable dissipation and a tunable transversal magnetic field, enabling the study of the dynamics and steady-states of dissipative spin models. As an example of effects made accessible this way, we consider small spin chains and weak dissipation and show by numerical simulation that steady-state expectation values display pronounced peaks at certain critical system parameters. We show that this effect is related to degeneracies in the Hamiltonian and derive a sufficient condition for its occurrence.

description: O Estudo teve como objetivo principal compreender a forma como se elaboram as representações sociais dos penitentes do Sítio de  Cabeceiras, no município de Barbalha-CE, sobre a prática do flagelo, enquanto forma de penitência. Utilizou-se como suporte metodológico a Teoria das Representações Sociais (TRS), uma vez que a mesma é considerada como uma forma de saber prático, elaborado no âmbito dos fenômenos comunicacionais e que  reflete as interações e mudanças sociais.  O mundo dos Penitentes Irmãos da Cruz, seus cânticos, chamados benditos e incelências, suas Representações Sociais da morte do morrer e das intervenções divinas nesses fenômenos, constituíram o foco de interesse deste estudo.  A análise das representações sociais sobre a temática permitiram a identificação de aspectos do modo de pensar e de agir desse grupo, com relação à construção do sentido de pertença e o conteúdo subjetivo da realidade ali vivenciada. Procurou-se compreender de que forma este fenômeno encontra-se implicado na vida cotidiana dos atores sociais envolvidos.  A amostra constituiu-se de cinquenta e cinco sujeitos, todos moradores do Sítio de Cabaceiras. Os instrumentos utilizados para a coleta dos dados foram: a associação livre de palavras e entrevistas semi-dirigidas. Os dados foram analisados por meio da análise de conteúdo (BARDIN, 1978) e pelo programa Tri-deux-mots (CIBOIS, 1998). Os resultados apontam para uma indissociabilidade entre o conceito de "penitência" e de "ser penitente"; demonstrou-se que estas expressões encontram-se intimamente associados a religião, a coisa boa, que faz bem a alma, que faz ser feliz e viver bem com o outro, sem briga, sem bebida. Quanto ao flagelo, é representado como vida de Jesus, é desejo de Deus, é fé, é comunicar-se com Deus, é o bem da alma, maneira de representar a vida de Jesus, comparando com o que Jesus sofreu por nós, nas expressões dos sujeitos da pesquisa.
