description: Distribution of quantum entanglement is investigated for an anisotropic quantum XY model with variable range interactions and in the presence of a uniform transverse magnetic field. We report the possibility of \emph{qualitative} growth in the entanglement between distant sites with an increase in the range of interactions that vary either exponentially or polynomially as the distance between the sites increases. Interestingly, we find that such entanglement enhancement is not ubiquitous and is dependent on the factorization points, a specific set of system parameters where the zero-temperature state of the system is fully separable. In particular, we observe that at zero-temperature, when the system parameters are chosen beyond the pair of factorization points, the increments in entanglement length due to variable range interactions are more pronounced compared to the situation when the parameters lie in between the factorization points. By employing the sum of all the bipartite entanglements with respect to a single site, we also show that the shareability of the bipartite entanglements are constrained, thereby establishing their monogamous nature. Furthermore, we note that the factorization points get reallocated depending on the laws of interaction fall-offs and provide an ansatz for the same. We reveal that the temperature at which the canonical equilibrium state becomes entangled from an unentangled one increases with the increase in the range of interactions, thereby demonstrating enhanced robustness in entanglement against temperature in the presence of long-range interactions and only when the system parameters are chosen between the pair of factorization points. We apply an energy-based entanglement witness to provide a justification to the observed robustness with temperature.

description: Na literatura da área de estratégia de operações, os critérios competitivos devem ser priorizados tendo como referência a importância desses para os clientes, o desempenho da comparativo aos concorrentes, os trade-offs existentes entre os critérios e a disponibilidades de recursos estratégicos. Entretanto, há uma lacuna na literatura de como fazer essa escolha. Nesse sentido foi realizada a revisão da literatura sobre os temas análise estratégica de operações e teoria baseada em recursos com vistas a contribuir para o entendimento de como os recursos estratégicos se associam com os critérios competitivos. Dessa revisão foi proposto um framework de análise. Esse framework foi pré-testado em duas grandes empresas de Canoas-RS. Durante essa etapa foram realizadas observações diretas nas empresas e entrevistas. Os resultados mostram que um recurso específico pode contribuir com vários critérios competitivos, não havendo uma relação específica entre um recurso estratégico e um critério competitivo em particular e que o framework pode ser utilizado para pesquisas futuras.-----------------------------------------------In the literature of the field of strategy of operations, the competitive criteria must be priorized having as reference the importance of those for the clients, the comparative performance for the competitors, the existing trade-offs between the criteria and the availability of strategic resources. Therefore, there is a lack in the literature in how to make this choice. In this sense, it was carried out a revision of the literature about the themes strategic analysis of operations and theory based on resources aiming to contribute for the understanding of how the strategic resources associate with the competitive criteria. From this revision was proposed a framework of analysis. This framework was pre-tested in two big companies in Canoas, State of Rio Grande do Sul. In the time of this stage, direct observations were carried out in the companies and in the interviews. The results show that a specific resource can contribute with several competitive criteria, not having a specific relation between a strategic resource and a specific competitive criteria and that the framework can be used for future researches.
Warm and Cold Dark Matter in Bouncing Universe

subject: FOS: Physical sciences

description: Being free from the initial singularity, bouncing cosmology serves as a promising alternative to inflation. However, the entropy production during the post-bounce phase is still unclear. In this work, we use a newly unveiled DM candidate (EQFIDM), which can directly freeze in thermal equilibrium shortly after bounce, to trace the entropy-producing decay process of residual bouncing field (RBF). Specifically, we present a model-independent formalism to obtain all nine possible types of the entropy-producing decay of RBF within a generic bouncing universe, and show that, due to the entropy productions in different types, the particle mass of this new candidate can range from sub-keV scale to super-TeV scale. With current Lyman-$α$ forest observation on linear matter spectrum, we find that, although four types have been excluded, the rest five types, which suggest warm and cold EQFIDM candidates with effective entropy productions, are accommodated with current observation. Then we illustrate how the nature of RBF can be constrained by current observation and investigate the potential of EQFIDM on alleviating small-scale crisis.

The Embedded Experience of Racialised Space. The Case of the Descendants of Algerians in Marseille Through the Sayad’s Gaze
Creators: name: Ragone, Marianna
Publisher: name: Italian Sociological Review
Year: 2025

description: In this contribution, we will attempt, in line with the legacy left to us by Abdelmalek Sayad, to start from spatial conditions in order to analyse more broadly the national/not national representations made by the descendants of Algerians, born and raised in France. The investigation will be based on ethnographic research carried out in the Belsunce neighbourhood in Marseille, which began in September 2022 and ended in September 2023. The questions the research aims to answer are: what is the representation of spaces made by young descendants of Algerians? How does the neighbourhood participate in the production and reproduction of the national/non-national categorisation (Sayad, 1979) that affects the descendants of migrants?  The article therefore questions the description of Belsunce made by some young descendants of Algerians women and men who live there or work there. Through their words, their reflections and the observation of the spatial practices they implement, it is possible to notice how Belsunce, and therefore Marseille as a whole, is the product of the persistent effects of the colonial organisation of space and also how the neighbourhood participates in the reproduction of processes of colonial categorisation and racialisation; French/non-French, national/non-national, civilised/uncivilised, integrated/barbarians. Confirming that space is not only structured but also structuring.

description: Bossa is a framework to develop new processes schedulers in commodity operating systems. Although Bossa enables fine-grained management of the processor through new scheduling policies, deploying an application with its own scheduler raises some problems. In this paper we study the problems caused when deploying an application and its scheduler and to adresse these, we propose to establish Quality of Service contracts and mechanisms to reconfigure the scheduler hierarchy.

description: A sample of isolated Earth-impacting ICMEs that occurred in the period January 2008 to August 2014 is analysed in order to study in detail the ICME in situ signatures with respect to the type of filament eruption related to the corresponding CME. For Earth-directed CMEs, a kinematical study was performed using the STEREO-A, B COR1 and COR2 coronagraphs and the Heliospheric Imagers HI1. Based on the extrapolated CME kinematics, we identified interacting CMEs, which were excluded from further analysis. Applying this approach, a set of 31 isolated Earth-impacting CMEs was unambiguously identified and related to the in situ measurements recorded by the Wind spacecraft. We classified the events into subsets with respect to the CME source location as well as with respect to the type of the associated filament eruption. Hence, the events are divided into three subsamples: active region (AR) CMEs, disappearing filament (DSF) CMEs, and stealthy CMEs. The related three groups of ICMEs were further divided into two subsets: magnetic obstacle (MO) events (out of which four were stealthy), covering ICMEs that at least partly expose characteristics of flux ropes, and ejecta (EJ) events, not showing such characteristics. In the next step, MO-events were analysed in more detail, considering the magnetic field strengths and the plasma characteristics in three different segments of the ICMEs, defined as the turbulent sheath (TS), the frontal region (FR), and the MO itself. The analysis revealed various well-defined correlations for AR, DSF, and stealthy ICMEs, which we interpreted considering basic physical concepts. Our results support the hypothesis that ICMEs show different signatures depending on the in situ spacecraft trajectory, in terms of apex versus flank hits.

description: A vortex line is shaped by a zigzag of pinning centers and we study here how far the stretched vortex line is able to follow this path. The pinning center is described by an insulating sphere of coherence length size such that in its surface the de Gennes boundary condition applies. We calculate the free energy density of this system in the framework of the Ginzburg-Landau theory and study the critical displacement beyond which the vortex line is detached from the pinning center.

The impact of overcrowding on the practice environment for emergency department nurses
Creators: name: Gillrie, Clay Douglas
Publisher: name: University of British Columbia
Year: 2009

description: Overcrowding in the Emergency Department (ED) occurs when there is an imbalance between resource supply and demand. In other words, the ED is challenged to provide quality care within acceptable time frames. Overcrowding literature illustrates that ED overcrowding has become so common that it is now considered normal, which begs the question: are terms such as "overcrowded" still pertinent to the current context of the ED environment in which overcrowding is a normal state? A recent and growing body of Canadian literature describes negative workplace environments in acute care facilities, but there is as yet no literature that examines overcrowding in relation to workplace environments in the ED. This interpretive descriptive study examines the relationship of overcrowding to the practice environment of emergency departments. Data were collected over six months and included in-depth interviews with ten experienced emergency department nurses. These data illustrate the negative impact of overcrowding on the emergency department environment. Emergency department overcrowding has occurred in parallel with fundamental restructuring of the health care system, creating a new era environment. This new environment is characterized by chronic overcrowding and an equally chronic shortage of resources. Within this environment nurses face several new challenges, such as understanding the discourse of overcrowding, reconciling conflicting values, and navigating the cycles of tension that arise from this new situation. Many of the changes to the ED have resulted from changes imposed elsewhere in the system, such as the closure of acute care beds. EDs are consequently in a state of transition as health care providers attempt to put the pieces back together. Within this new era environment many challenges have emerged and data analysis suggests that new era EDs support negative workplace environments. It is crucial that policy makers be well informed when making decisions that impact EDs. In order to be able to influence policy makers it is essential that nurses be proactive and involved in charting the course for the future. It is also necessary for organizations to invest in leadership by creating appropriate positions at appropriate levels so that leaders can be visible and available to create vision and help nurses through the transition to the new era environment. This study argues for the need to create an increased body of research that will inform policy makers about how ED overcrowding negatively affects the practice environment.

description: One of the important unsolved problems in information theory is the conjecture that network coding has no rate benefit over routing in undirected unicast networks. Three known bounds on the symmetric rate in undirected unicast information networks are the sparsest cut, the LP bound and the partition bound. In this paper, we present three results on the partition bound. We show that the decision version problem of computing the partition bound is NP-complete. We give complete proofs of optimal routing schemes for two classes of networks that attain the partition bound. Recently, the conjecture was proved for a new class of networks and it was shown that all the network instances for which the conjecture is proved previously are elements of this class. We show the existence of a network for which the partition bound is tight, achievable by routing and is not an element of this new class of networks.

Para tanto foram levantados junto a uma agroindústria de atomatados os dados de consumo e parâmetros técnicos do vapor, e baseado nestas informações foi desenvolvido um modelo de simulação. A metodologia utilizada foi o System Dynamics a qual auxiliou no desenvolvimento de um modelo composto por quatro módulos: o módulo da matriz energética agroindustrial, o módulo demandador de vapor, o módulo ofertador de vapor e o módulo financeiro, que trata inúmeras variáveis de forma aleatória com a utilização de curvas de distribuição normal e ferramentas randômicas para valores que variam entre intervalos. Através do modelo que utiliza recursos aleatórios tem-se, de forma estocástica, a geração do vapor e seu custo. Possibilitando a construção de cenários, que auxilia a percepção do processo de produção do vapor e tomadas de decisões por parte de diretores e gerentes industriais. ------------------------------------------------------------------The objective of this paper was to presentation the result of the work was to develop a system of management expenditure of random form of the saturated steam for the industry.

description: Interest in Brownian motion was shared by different communities: this phenomenon was first observed by the botanist Robert Brown in 1827, then theorised by physicists in the 1900s, and eventually modelled by mathematicians from the 1920s, while still evolving as a physical theory. Consequently, Brownian motion now refers to the natural phenomenon but also to the theories accounting for it. There is no published work telling its entire history from its discovery until today, but rather partial histories either from 1827 to Perrin's experiments in the late 1900s, from a physicist's point of view; or from the 1920s from a mathematician's point of view. In this article, we tackle the period straddling the two `half-histories' just mentioned, in order to highlight continuity, to investigate the domain-shift from physics to mathematics, and to survey the enhancements of later physical theories. We study the works of Einstein, Smoluchowski, Langevin, Wiener, Ornstein and Uhlenbeck from 1905 to 1934 as well as experimental results, using the concept of Brownian velocity as a leading thread. We show how Brownian motion became a research topic for the mathematician Wiener in the 1920s, why his model was an idealization of physical experiments, what Ornstein and Uhlenbeck added to Einstein's results, and how Wiener, Ornstein and Uhlenbeck developed in parallel contradictory theories concerning Brownian velocity.

Our approach combines a quantum mechanical treatment of the photon's initial state interactions with a semi-classical coupled channel simulation of the (pre)hadronic final-state interactions (FSI). This allows us to study the hadron attenuation observed at HERMES and to get information on the space-time picture of hadron formation separately for $π^{\pm}$, $π^0$, $K^\pm$, $p$ and $\bar{p}$.

description: Ao longo do período 2000/2007 o setor externo do agronegócio brasileiro encontrou uma conjuntura altamente favorável para o aumento de suas exportações, pois se combinou uma situação de forte expansão da economia mundial com elevação dos preços internacionais de commodities. No âmbito interno, os ganhos de produtividade permitiram o avanço das exportações, enquanto que a valorização cambial, iniciada em meados de 2004, praticamente eliminou os efeitos positivos da elevação dos preços internacionais. Esse trabalho mostra que, a despeito dos efeitos negativos da valorização cambial, o crescimento das importações mundiais teve efeito relevante (em torno de 20%) no aumento das exportações brasileiras do agronegócio entre os anos de 2000 e 2007.-----------------------------------------------Over the period 2000/2007 the external sector of Brazilian agribusiness found a favorable environment to increase their exports, which combined a situation of strong expansion of the world economy with elevation in international commodities prices. On the domestic front, productivity gains enabled the progress of exports, while the exchange rate overvaluation, which began in mid-2004, virtually eliminated the positive effects of the international prices increasing. This work shows that, despite the negative effects of exchange rate overvaluation, the growth of world imports took relevant effect (around 20%) on the Brazilian agribusiness exports evolution on the period from 2000 to 2007.

description: Software components turn out to be a convenient model to build complex applications for scientific computing and to run them on a computational grid. However, deploying complex, component-based applications in a grid environment is particularly arduous. To prevent the user from directly dealing with a large number of execution hosts and their heterogeneity within a grid, the application deployment phase must be as automatic as possible. This paper describes an architecture for automatic deployment of component-based applications on computational grids. In the context of the CORBA Component Model (CCM), this paper details all the steps to achieve an automatic deployment of components as well as the entities involved: a grid access middleware and its grid information service (like OGSI), a component deployment model, as specified by CCM, an enriched application description and a deployment planner in order to select resources and map components onto computers.

description: The article presents a proposal to contextualize the study of movement in first courses of university physics, as a contribution to decision-making in situations of a social nature. For this, the case of the use of kinetic impact projectiles and the actual data provided by official sources is considered. This information is used in an object motion model describing the kinematic characteristics of a spherical projectile (a rubber bullet). For these purposes, a number Reynolds Re >> 1 was used, which allows applying a nonlinear motion equation to find the velocity and impact energy per unit area of projectile. Results and analysis of this model can generate an interesting discussion in the classroom about the need to build protocols for the use of kinetic impact projectiles, and the importance of using scientific knowledge in social conflicts.

description: We show that the combined action of diffraction and convection (walk-off) in wave mixing processes leads to a nonlinear-symmetry-breaking in the generated traveling waves. The dynamics near to threshold is reduced to a Ginzburg-Landau model, showing an original dependence of the nonlinear self-coupling term on the convection. Analytical expressions of the intensity and the velocity of traveling waves emphasize the utmost importance of convection in this phenomenon. These predictions are in excellent agreement with the numerical solutions of the full dynamical model.

description: We study some aspects of localized tachyon condensation on non-supersymmetric orbifolds of the form $\BC^2/\BZ_n$ and $\BC^3/\BZ_n$. We discuss the gauged linear sigma models for these orbifolds. We show how several features of the decay of orbifolds of $\BC^3$ can be realised in terms of orbifolds of $\BC^2$.

What’s in store : exploring design for community, mixed-use and greening in the retail landscape
Creators: name: Good, Allison Mary
Publisher: name: University of British Columbia
Year: 2009

description: The project was a conceptual design development based on precedent exploring, in particular, the retail environment and its relationship to the development of urban sustainability. Three major areas of focus were researched and synthesized to inform design principles: the shopping center as community focus; the development of mixed, multi and adaptive uses to complement retail; and the need for greening of traditional retail landscapes. The principles developed from this research are intended for application to retail development and have been illustrated via conceptual redesign of a 30-acre shopping center in Kingston, Ontario. Through conceptual and detailed design, the project indicates how a retail-focused environment can contribute to a healthier and more vibrant urban landscape through enhanced community connections, range of uses on site and improved green infrastructure.
Detection of Topology via Entanglement Oscillations

description: We introduce a characterization of topological order based on bulk oscillations of the entanglement entropy and the definition of an `entanglement gap', showing that it is generally applicable to pure and disordered quantum systems. Using exact diagonalization and the strong disorder renormalization group method, we demonstrate that this approach gives results in agreement with the use of traditional topological invariants, especially in cases where topological order is known to persist in the presence of off-diagonal bond disorder. The entanglement gap is then used to analyze classes of quantum systems with alternating bond types, allowing us to construct their topological phase diagrams. The validity of these phase diagrams is verified in limiting cases of dominant bond types, where the solution is known.

description: The dust extinction in spiral disks can be estimated from the counts of background field galaxies, provided the deleterious effects of confusion introduced by structure in the image of the foreground spiral disk can be calibrated. Gonzalez et al. (1998) developed a method for this calibration, the ``Synthetic Field Method'' (SFM), and applied this concept to a HST/WFPC2 image of NGC4536. The SFM estimates the total extinction through the disk without the necessity of assumptions about the distribution of absorbers or the disk light. The poor statistics, however, result in a large error in individual measurements. We report on improvements to and automation of the Synthetic Field Method which render it suitable for application to large archival datasets. To illustrate the strengths and weaknesses of this new method, the results on NGC 1365, a SBb, and NGC 4536, a SABbc, are presented. The extinction estimate for NGC1365 is A_I = 0.6 (+0.6/-0.7) at 0.45 R_25 and for NGC4536 it is A_I = 1.6 (+1.0/-1.3) at 0.75 R_25. The results for NGC4536 are compared with those of Gonzalez et al. (1998). The automation is found to limit the maximum depth to which field galaxies can be found. Taking this into account, our results agree with those of Gonzalez et al. (1998). We conclude that this method can only give an inaccurate measure of extinction for a field covering a small solid angle. An improved measurement of disk extinction can be done by averaging the results over a series of HST fields, thereby improving the statistics. This can be achieved with the automated method, trading some completeness limit for speed. The results from this set of fields are reported in a companion paper Holwerda et al. (2005b).

description: Special relativity is generalized to extra dimensions and quantized energy levels of particles are obtained. By calculating the probability of particles' motion in extra dimensions at high temperature of the early universe, it is proposed that the branes may have not existed since the very beginning of the universe, but formed later. Meanwhile, before the formation, particles of the universe may have filled in the whole bulk, not just on the branes. This scenario differs from that in the standard big bang cosmology in which all particles are assumed to be in the 4D spacetime. So, in brane models, whether our universe began from a 4D big bang singularity is questionable. A cosmological constraint on the number of extra dimensions is also given which favors $N\geq 7$.

White Dwarf Heating and Subsequent Cooling in Dwarf Nova Outbursts

description: We follow the time dependent thermal evolution of a white dwarf (WD) undergoing sudden accretion in a dwarf nova outburst, using both simulations and analytic estimates. The post-outburst lightcurve clearly separates into early times when the WD flux is high, and late times when the flux is near the quiescent level. The break between these two regimes, occurring at a time of order the outburst duration, corresponds to a thermal diffusion wave reaching the base of the freshly accreted layer. Our principal result is that long after the outburst, the fractional flux perturbation about the quiescent flux decays as a power law with time (and {\it not} as an exponential). We use this result to construct a simple fitting formula that yields estimates for both the quiescent flux and the accreted column, i.e. the total accreted mass divided by WD surface area. The WD mass is not well constrained by the late time lightcurve alone, but it can be inferred if the accreted mass is known from observations. We compare our work with the well-studied outburst of WZ Sge, finding that the cooling is well described by our model, giving an effective temperature $T_{\rm eff}=14,500 {\rm K}$ and accreted column $Δy\approx10^6 {\rm g cm^{-2}}$, in agreement with the modeling of Godon et al. To reconcile this accreted column with the accreted mass inferred from the bolometric accretion luminosity, a large WD mass $\gtrsim1.1M_\odot$ is needed. Our power law result is a valuable tool for making quick estimates of the outburst properties. We show that fitting the late time lightcurve with this formula yields a predicted column within 20% of that estimated from our full numerical calculations.

Irreducibility of the Fermi variety for discrete periodic Schrödinger operators and embedded eigenvalues

description: Let $H_0$ be a discrete periodic Schrödinger operator on $\ell^2(\mathbb{Z}^d)$: $$H_0=-Δ+V,$$ where $Δ$ is the discrete Laplacian and $V: \mathbb{Z}^d\to \mathbb{C}$ is periodic. We prove that for any $d\geq3$, the Fermi variety at every energy level is irreducible (modulo periodicity). For $d=2$, we prove that the Fermi variety at every energy level except for the average of the potential is irreducible (modulo periodicity) and the Fermi variety at the average of the potential has at most two irreducible components (modulo periodicity). This is sharp since for $d=2$ and a constant potential $V$, the Fermi variety at $V$-level has exactly two irreducible components (modulo periodicity). We also prove that the Bloch variety is irreducible (modulo periodicity) for any $d\geq 2$. As applications, we prove that when $V$ is a real-valued periodic function, the level set of any extrema of any spectral band functions, spectral band edges in particular, has dimension at most $d-2$ for any $d\geq 3$, and finite cardinality for $d=2$. We also show that $H=-Δ+V+v$ does not have any embedded eigenvalues provided that $v$ decays super-exponentially.
