description: In this paper, we consider the dynamics of a heavy homogeneous ball moving under the influence of dry friction on a fixed horizontal plane. We assume the ball to slide without rolling. We demonstrate that the plane may be divided into two regions, each characterized by a distinct coefficient of friction, so that balls with equal initial linear and angular velocity will converge upon the same point from different initial locations along a certain segment. We construct the boundary between the two regions explicitly and discuss possible applications to real physical systems.

description: Using a sample of ~410 000 galaxies to depth I_AB = 24 over 8.26 deg^2 in the Bootes field (~10 times larger than z~1 luminosity function studies in the prior literature), we have accurately measured the evolving B-band luminosity function of red galaxies at z<1.2 and blue galaxies at z<1.0. In addition to the large sample size, we utilise photometry that accounts for the varying angular sizes of galaxies, photometric redshifts verified with spectroscopy, and absolute magnitudes that should have very small random and systematic errors. Our results are consistent with the migration of galaxies from the blue cloud to the red sequence as they cease to form stars, and with downsizing in which more massive and luminous blue galaxies cease star formation earlier than fainter less massive ones. Comparing the observed fading of red galaxies with that to be expected from passive evolution alone, we find that the stellar mass contained within the red galaxy population has increased by a factor of ~3.6 from z~1.1 to z~0.1. The bright end of the red galaxy luminosity function fades with decreasing redshift, the rate of fading increasing from ~0.2 mag per unit redshift at z = 1.0 to ~0.8 at z = 0.2. The overall decrease in luminosity implies that the stellar mass in individual highly luminous red galaxies increased by a factor of ~2.2 from z = 1.1 to z = 0.1.

description: This study is an investigation into the social nature of self-care. Using the specific case of a phenomenon that I refer to as “progressive self-care,” I study a collection of groups that come together in order to practice a form of self-care that attempts to remove itself from capitalist productivity and consumption practices. Using Patricia Hill Collins’ Black Feminist Theory and Paula England’s Care as a Public Good framework, I find that groups attempt to politicize the nature of their meetings and the discourses surrounding rest, identity, and care in order to differentiate their practices from mainstream practices. I also find that collectivity is central to progressive self-care because it is fundamentally a collective practice, not an individual one. Finally, I find that progressive self-care practitioners use selfcare practices and discourses to dissect meanings of care and care work. I finish this study by discussing the implications of this work for further sociological research

description: We examine finite-temperature phase transitions in the two-orbital Hubbard model with different bandwidths by means of the dynamical mean-field theory combined with the continuous-time quantum Monte Carlo method. It is found that there emerges a peculiar slope-reversed first-order Mott transition between the orbital-selective Mott phase and the Mott insulator phase in the presence of Ising-type Hund's coupling. The origin of the slope-reversed phase transition is clarified by the analysis of the temperature dependence of the energy density. It turns out that the increase of Hund's coupling lowers the critical temperature of the slope-reversed Mott transition. Beyond a certain critical value of Hund's coupling the first-order transition turns into a finite-temperature crossover. We also reveal that the orbital-selective Mott phase exhibits frozen local moments in the wide orbital, which is demonstrated by the spin-spin correlation functions.

Valuing newspaper website content: what people are willing to pay for and why
Creators: name: Hussman, Mary Eliza
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: This paper investigates whether people are willing to pay to access a newspaper website that charges for content, and what news they'll pay for. This is important as it directly relates to the economic vitality of the newspaper industry, which hasn't crafted sustainable business models for digital editions. A survey of online readers of a mid-sized newspaper indicates a willingness to pay for exclusive digital content, especially local news. A majority of subscribers felt the price for online access (less than $20) was a fair price and indicated they'd become online-only subscribers if a print edition wasn't available. Nonsubscribers were more likely to feel the price was too high and seek substitute sources for local news. Roughly half of nonsubscribers said they'd consider subscribing if the price decreased. The results raise questions about pricing elasticity of subscriber models and the consumer's evolving attitude toward paying for digital information.

description: Für den Schmerz und die Ausweglosigkeit unglücklicher Liebe gibt es keine Lösung. Vielmehr zwingt uns die Situation in eine Transformation. Ähnlich wie die Menschen zu Zeit des Kolumbus auf die Entdeckung Indiens auf dem westlichen Seeweg fixiert waren, dann aber hinter der Enttäuschung eine neue Welt entdeckten, kann auch die genannte Transformation zu etwas ganz Neuem führen. Dem Blick zurück auf die Zeit einer unglücklichen Verliebtheit entsprechen verschiedene philosophische Einstellungen, die eine Nähe zur Melancholie zeigen.
description: There is no solution for unrequited or unhappy love, no way out. Life forces us to transform ourselves. This transformation can, possibly, open us for something really new. Columbus and his contemporaries were firmly focused on reaching India by the western sea route, were disappointed and, then, discovered something completely new. Likewise, our transformation in which unhappy love forces us can lead us to something new. Philosophical and melancholic attitudes towards the depth of life are being discussed.
Seeing absence

description: Intuitively, we often see absences. For example, if someone steals your computer from a café, you may see its absence from your table. But absence perception presents a paradox. On prevailing models of perception, we see only present objects and scenes. So, we cannot literally see an object that is not present. This suggests that we never literally perceive absences, but merely infer that something is absent cognitively on the basis of what we do perceive. But this cognitive explanation does not do justice to the phenomenology. In this paper, I argue that we can literally see absences. I present a model of absence perception based on visual expectations and a matching process. I then reply to two pressing objections.

description: A stochastic second-order wave model is applied to assess the statistical properties of wave orbital velocity in random sea states below the water surface. Directional spreading effects as well as the dependency of the water depth are investigated by means of a Monte-Carlo approach. Unlike for the surface elevation, sub-harmonics dominate the second-order contribution to orbital velocity. We show that a notable set-down occurs for the most energetic and steepest groups. This engenders a negative skewness in the temporal evolution of the orbital velocity. A substantial deviation of the upper and lower tails of the probability density function from the Gaussian distribution is noticed, velocities are faster below the wave trough and slower below the wave crest when compared with linear theory predictions. Second-order nonlinearity effects strengthen with reducing the water depth, while weaken with the broadening of the wave spectrum. The results are confirmed by laboratory data. Corresponding experiments have been conducted in a large wave basin taking into account the directionality of the wave field. As shown, laboratory data are in very good agreement with the numerical prediction.

Transitive Inference and The Testing Effect: The Effects of Testing on Knowledge Structure Formation
Creators: name: Picklesimer, Milton
Publisher: name: University of North Carolina at Chapel Hill
Year: 2012

description: Compared to restudying, testing has often been found to enhance memory. This is called the testing effect. However, the causes of this effect are not entirely understood. Testing could merely enhance isolated stimulus-response associations (i.e., item memory) or also enhance the unifying structure of the memoranda (i.e., relational memory). Recent studies have examined these issues with mixed results. The current study employed a transitive inference paradigm to teach participants a novel, highly inter-related knowledge structure comprised of several basic premises. Encoding strategy was manipulated between subjects. Both groups took a final test that assessed memory for the basic premises and their ability to make transitive inferences about them. Experiment 1 found no differences between the groups. After using a stronger manipulation in Experiment 2, it was found that, for participants who indicated awareness of the hierarchical structure of the materials, there were no differences between encoding conditions. For unaware participants, however, the restudying group showed superior performance on transitive inference problems. Thus, the current study identified conditions under which testing does not enhance inferential ability or memory for the unifying structure of the memoranda.
On Gröbner Bases and Krull Dimension of Residue Class Rings of Polynomial Rings over Integral Domains

description: Given an ideal $\mathfrak{a}$ in $A[x_1, \ldots, x_n]$, where $A$ is a Noetherian integral domain, we propose an approach to compute the Krull dimension of $A[x_1,\ldots,x_n]/\mathfrak{a}$, when the residue class polynomial ring is a free $A$-module. When $A$ is a field, the Krull dimension of $A[x_1,\ldots,x_n]/\mathfrak{a}$ has several equivalent algorithmic definitions by which it can be computed. But this is not true in the case of arbitrary Noetherian rings. For a Noetherian integral domain, $A$ we introduce the notion of combinatorial dimension of $A[x_1, \ldots,x_n]/\mathfrak{a}$ and give a Gröbner basis method to compute it for residue class polynomial rings that have a free $A$-module representation w.r.t. a lexicographic ordering. For such $A$-algebras, we derive a relation between Krull dimension and combinatorial dimension of $A[x_1, \ldots, x_n]/\mathfrak{a}$. An immediate application of this relation is that it gives a uniform method, the first of its kind, to compute the dimension of $A[x_1, \ldots, x_n]/\mathfrak{a}$ without having to consider individual properties of the ideal. For $A$-algebras that have a free $A$-module representation w.r.t. degree compatible monomial orderings, we introduce the concepts of Hilbert function, Hilbert series and Hilbert polynomials and show that Gröbner basis methods can be used to compute these quantities. We then proceed to show that the combinatorial dimension of such $A$-algebras is equal to the degree of the Hilbert polynomial. This enables us to extend the relation between Krull dimension and combinatorial dimension to $A$-algebras with a free $A$-module representation w.r.t. a degree compatible ordering as well.
A converter for DDI: From CodeBook to Lifecycle

Year: 2020

description: On earlier conferences, we talked about the concepts of our approach for efficient management of DDI files for documentation applications called DDI-FlatDB. We also showed how to use this approach for bringing metadata into search and dissemination applications, e.g. the GESIS Questionnaire Editor. Now we want to share the experiences using DDI-FlatDB when it comes to convert instances between major DDI versions, e.g. DDI CodeBook 2.5 to DDI Lifecycle 3.2 This conversion of DDI is an absolute necessity to support infrastructures to convert their metadata for the use in new arising documentation tools or for the development of such tools and services. A general point is, that we promised, that we could convert any DDI version to another, just by configuration files. But due to significant different models, e.g. CodeBook vs Lifecycle, we realized, that still programmatic work is needed. Making e.g. question texts, codes and categories from NESSTAR or DDI 2.x variables usable within applications that were implemented along DDI 3.x is challenging. Based on the splitting and entity parsing mechanisms of DDI-FlatDB, we managed to create a converting path from e.g. NESSTAR outputs from various sources into DDI LC 3.2 on variable and question level. This is the first step for indexing questions for the CESSDA European Question Bank search portal or the GESIS ExploreData Variable search portal. We will present the open source conversion tool and describe the process and the lessons learned. Recorded version of the whole session: https://youtu.be/mAXlABqemik
Transition to Decentralized Energy in Cities through a Complex Systems Approach

Publisher: name: University of Illinois at Chicago

description: Energy infrastructure systems, traditionally known for their reliability in providing energy access, are undergoing transformative changes due to recent advancements in technology and the rise of decentralized systems and renewable energy sources. This shift in energy systems is altering the dynamics of socio-technical interactions within urban environments and influencing consumer behavior, further impacting the energy landscape. Policymakers play a critical role in facilitating this transition, necessitating a comprehensive understanding of energy systems as complex socio-technical entities. This dissertation aims to equip stakeholders in the energy market with a valuable instrument for assessing the potential consequences of policies and technologies, providing guidance for urban planners in managing the transition. Using a modeling framework and methods such as causal loop diagramming, system dynamics, and graph theory, the research evaluates diverse strategies for stakeholders in the transition to decentralized energy systems. The study focuses on the state of Illinois (USA), which is committed to renewable energy reliance and climate neutrality by 2050. The policies and strategies in Illinois are compared and partly informed by the policies in European Union (Denmark, in particular), examining their energy planning strategies and the roles of various levels of government in shaping the landscape. The system dynamics model frames and evaluates several potential scenarios of the energy market development for the following decades, and the application of graph theory to a causal loop diagram quantitatively analyzes key variables driving and reinforcing the transition. The study identifies profit-driven approaches, technological progress, energy visibility, long-term strategic planning, and sustainable urban practices as crucial factors influencing the widespread adoption of decentralized energy systems. These findings contribute valuable insights to support the integration of decentralized grids into urban planning agendas and promote a sustainable transition to renewable energy reliance.

An In-Depth Analysis of After-Hours Pediatric Emergency Dental Care
Creators: name: Brecher, Erica
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Objectives: To examine after-hours emergency dental care guidelines and assess related practice patterns of pediatric dentists (PD) and general dentists (GD). Methods: State and national guidelines were examined for language pertaining to after-hours emergency care. A 29-item survey was distributed to PD and GD in North Carolina, assessing demographics and after-hours practice patterns. Respondents were called to validate reported after-hours protocol. Results: Most states followed American Dental Association guidelines, suggesting dentists make reasonable arrangements for the emergency dental care of patients. Eighty-six(46%) PD and 1199(36%) GD completed the survey. More PD than GD had after-hours protocol, practiced in a group, and shared call. Telephone and survey responses significantly differed for GD but not PD. Conclusions: Current after-hours emergency guidelines are nonspecific and open to interpretation. More PD than GD provided comprehensive, continuously accessible dental care. These results highlight gaps in emergency dental practice and a breakdown in the dental home.

description: Hagedorn states (HS) are a tool to model the hadronization process which occurs in the phase transition region between the quark gluon plasma (QGP) and the hadron resonance gas (HRG). These states are believed to appear near the Hagedorn temperature $T_H$ which in our understanding equals the critical temperature $T_c$. A covariantly formulated bootstrap equation is solved to generate the zoo of these particles characterized baryon number $B$, strangeness $S$ and electric charge $Q$. These hadron-like resonances are characterized by being very massive and by not being limited to quantum numbers of known hadrons. All hadronic properties like masses, spectral functions etc.are taken from the hadronic transport model Ultra Relativistic Quantum Molecular Dynamics (UrQMD). Decay chains of single Hagedorn states provide a well description of experimentally observed multiplicity ratios of strange and multi-strange particles. In addition, the final energy spectra of resulting hadrons show a thermal-like distribution with the characteristic Hagedorn temperature $T_H$. Box calculations including these Hagedorn states are performed. Indeed, the time scales leading to equilibration of the system are drastically reduced down to 2...5 fm/c.

In this paper we analyze the Shapley value (Shapley, 1953) of the game and propose its use as a measure of the players' attitude towards collusion. Furthermore, we relate the sign of the Shapley value with the ranking order of the players' evaluation, and show that some players in a given ranking will always deter collusion. Finally, we characterize the coalitions that maximize the gain from collusion, and suggest an ad-hoc coalition formation mechanism.

description: T2K-nd280-energy-dependent-ccqe-xsec-2014.tar
description: KEK. The Charged-Current Quasi-Elastic (CCQE) interaction, $\nu_{l} + n \rightarrow l^{-} + p$, is the dominant CC process at $E_\nu \sim 1$ GeV and contributes to the signal in accelerator-based long-baseline neutrino oscillation experiments operating at intermediate neutrino energies. This paper reports a measurement by the T2K experiment of the $\nu_{\mu}$ CCQE cross section on a carbon target with the off-axis detector based on the observed distribution of muon momentum ($p_\mu$) and angle with respect to the incident neutrino beam ($\theta_\mu$). The flux-integrated CCQE cross section was measured to be $(0.83 \pm 0.12) \times 10^{-38}\textrm{ cm}^{2}$ in good agreement with NEUT MC value of ${0.88 \times 10^{-38}} \textrm{ cm}^{2}$. The energy dependence of the CCQE cross section is also reported. Data points taken from attached tar file available at http://t2k-experiment.org/results/.

description: Recent studies suggest that faint active galactic nuclei may be responsible for the reionization of the universe. Confirmation of this scenario requires spectroscopic identification of faint quasars ($M_{1450}>-24$ mag) at $z \gtrsim6$, but only a very small number of such quasars have been spectroscopically identified so far. Here, we report the discovery of a faint quasar IMS J220417.92+011144.8 at z~6 in a 12.5 deg$^{2}$ region of the SA22 field of the Infrared Medium-deep Survey (IMS). The spectrum of the quasar shows a sharp break at $\sim8443~\rmÅ$, with emission lines redshifted to $z=5.944 \pm 0.002$ and rest-frame ultraviolet continuum magnitude $M_{1450}=-23.59\pm0.10$ AB mag. The discovery of IMS J220417.92+011144.8 is consistent with the expected number of quasars at z~6 estimated from quasar luminosity functions based on previous observations of spectroscopically identified low-luminosity quasars . This suggests that the number of $M_{1450}\sim-23$ mag quasars at z~6 may not be high enough to fully account for the reionization of the universe. In addition, our study demonstrates that faint quasars in the early universe can be identified effectively with a moderately wide and deep near-infrared survey such as the IMS.

description: Hardware and software of secured embedded systems are prone to physical attacks. In particular, fault injection attacks revealed vulnerabilities on the data and the control flow allowing an attacker to break cryptographic or secured algorithms implementations. While many research studies concentrated on successful attacks on the data flow, only a few targets the instruction flow. In this paper, we focus on electromagnetic fault injection (EMFI) on the control flow, especially on the instruction cache. We target the very widespread (smartphones, tablets, settop-boxes, health-industry monitors and sensors, etc.) ARMv7-M architecture. We describe a practical EMFI platform and present a methodology providing high control level and high reproducibility over fault injections. Indeed, we observe that a precise fault model occurs in up to 96% of the cases. We then characterize and exhibit this practical fault model on the cache that is not yet considered in the literature. We comprehensively describe its effects and show how it can be used to reproduce well known fault attacks. Finally, we describe how it can benefits attackers to mount new powerful attacks or simplify existing ones.

As Rotinas Jornalísticas como arma contra as Fake News
Creators: name: Batista, Margarida
Publisher: name: Aprender
Year: 2021

description: A informação manipulada com o propósito de se fazer passar por notícia tem gerado grande desconfiança dos cidadãos em relação aos média, numa sociedade que não está preparada para lidar com este género de situação. Os próprios media, tentando manter‐se como pioneiros das notícias, tentam também delinear estratégias de combate à desinformação. E a responsabilidade só aumenta se falarmos de agências noticiosas, como a Agência Lusa. Neste sentido, e numa primeira abordagem, recorremos a autores como Fontcuberta (2002), Kovach & Rosenstiel (2004) ou Ryfe (2012) de modo a discutirmos o conceito de verdade aplicado ao jornalismo, bem como a relevância das rotinas jornalísticas. Em seguida, e com base na observação direta das dinâmicas aplicadas na Lusa, além da análise de três entrevistas realizadas a profissionais da agência, identificaremos os principais mecanismos utilizados no combate às fake news, procurando ainda estimular a reflexão das seguintes questões: 1. A Agência Lusa atua de forma direta na luta contras as fake news? 2. As rotinas jornalísticas, como a verificação ou o contraditório, são respeitadas enquanto métodos de combate à desinformação? 3. A Lusa identifica‐se como agente ativo na estimulação da literacia mediática? No final, tentaremos discuti‐las enquanto mecanismos de combate manipulação informativa.

description: Previous studies have found that anterior cruciate ligament reconstructed (ACL-R), individuals demonstrate altered corticospinal excitability, quadriceps activation, and vertical ground reaction force (vGRF) loading rates during walking gait. Altered corticospinal excitability may influence the onset of quadriceps activity in preparation for heel strike, which could lead to an increased vGRF rate of loading. The purpose of this study was to determine the association between corticospinal excitability and vGRF rate of loading and quadriceps electromyography activity onset times during walking gait in ACL-R individuals. Individuals in this study participated in two testing sessions separated by at least one week. This study found a significant negative association between corticospinal excitability and vGRF rate of loading but no association between corticospinal excitability and quadriceps EMG onset times. The results of this study suggest that ACL-R individuals with higher corticospinal excitability have higher vGRF during walking gait.
Audiovisual e interação: práticas semióticas contemporâneas

description: Neste trabalho pretendemos uma reflexão sobre o audiovisual como uma prática semiótica contemporânea com características estéticas que promovem uma interação, a partir de experiências sensíveis propostas. Partimos, para isso, dos conceitos de tecnologia (Rudiger) e da narrativa audiovisual como manifestação (Barthes). Ampliamos a discussão buscando ‐ historicamente – explicar os momentos diferentes por quais passou o cinema e o audiovisual, com uma atenção especial aos conceitos de cinema interativo (Parente, 2007); de imersão de Janet Murray (2003) e de práticas de interação de Eric Landowski (2014). Por fim, observamos sob o olhar destes conceitos o videoclipe “De repente”, da banda brasileira Skank.

description: Many candidate multiquark mesons, i.e., mesons with substructures that are more complex than the quark-antiquark prescription that is in the textbooks, have recently been observed. Many of the most recently observed candidate states are electrically charged and have the same spin and parity, namely JP=1+. In this talk I give an overview of the current experimental situation and identify patterns among the recently discovered JP=1+ states, compare these patterns with expectations from proposed theoretical models, and the existence of additional, related states that might be accessible at current and future experiments. In addition, models that attribute the observed states to kinematically induced cusps are discussed.

description: Neste artigo, pretendemos refletir sobre a comunicação em saúde pública (CSP), um conceito de compreensão muito alargada e multidisciplinar. Discutimos e desconstruímos algumas ideias relacionadas com os direitos sociais na saúde pública. Finalmente, considerando a pertinência das estratégias de comunicação em saúde pública (ECSP) ou das estratégias de comunicação de crise em saúde pública (ECCSP) – Pandemia SARS‐COV2 – consideramos que é mandatório desenhar uma estratégia com os campos Comunicação em Saúde (CS), que envolva os seguintes elementos: Público‐Alvo (PA) + Mensagens‐chave (MC) + Produtos de comunicação (PC) = Ganhos em Saúde (GS).

O papel da Comunicação Interna em tempos de pandemia: uma resposta à crise da Covid‐19
Creators: name: Rodrigues, Rosália
Publisher: name: Aprender
Year: 2021

description: A comunicação organizacional é responsável pela criação e fortalecimento da identidade e imagem de uma organização, por meio de ações que promovam o diálogo e a interação com seus públicos, sejam eles internos (colaboradores e funcionários) ou externos (clientes, parceiros, imprensa e sociedade em geral). E, através da comunicação feita para os públicos, a organização dá a conhecer o comportamento organizacional da instituição, a sua missão, visão, e os valores e políticas orientadoras das práticas de trabalho, bem como os objetivos, enquanto instituição. Assim, as instituições têm de repensar as formas e os meios privilegiados de comunicação, agilizandoos face às mudanças, crises e disrupções. Partindo do princípio de que, no presente, a estrutura social concreta é a da sociedade‐rede, a estrutura social que caracteriza a sociedade no início do século XXI, uma estrutura social construída ao redor das redes digitais de comunicação, neste artigo, propomo‐nos refletir acerca do papel que a comunicação interna teve durante a pandemia e no futuro próximo.

description: Neste artigo analisa‐se a forma como se desencadearam os processos de comunicação no Instituto Politécnico de Portalegre, num momento particularmente difícil, inesperado e ímpar. Perante a que já se considera ser a mais feroz crise sanitária do presente século, a COVID‐19, que obrigou o mundo a parar, o Politécnico de Portalegre passou a funcionar à distância fazendo da comunicação digital o único instrumento para chegar junto dos seus públicos. Partindo da comunicação digital, foram contextualizadas e caracterizadas três categorias de comunicação: institucional, COVID‐19 e emocional. Analisaram‐se qualitativamente os conteúdos difundidos nas diversas plataformas digitais do Politécnico, no período compreendido entre os dias 9 de março (data do primeiro comunicado do Sr. Presidente) e 18 de maio de 2020 (data do início da segunda fase de desconfinamento), com o objetivo de observar os procedimentos adotados pela Instituição na gestão da comunicação neste contexto. O contributo científico deste artigo assenta no estudo dos processos de comunicação que foi necessário manter e reinventar de forma fluida, ágil e adaptada aos públicos‐alvo. Esta nova dinâmica comunicacional espelha o Politécnico de Portalegre como uma instituição aberta, inclusiva e sustentável.

description: In this work, we investigate the molecular gas and star formation properties in the barred spiral galaxy NGC 6946 using multiple molecular lines and star formation tracers. High-resolution image (100 pc) of $^{13}$CO (1-0) is created by single dish NRO45 and interferometer CARMA for the inner 2 kpc disk, which includes the central region (nuclear ring and bar) and the offset ridges of the primary bar. Single dish HCN (1-0) observations were also made to constrain the amount of dense gas. Physical properties of molecular gas are inferred by (1) the Large Velocity Gradient (LVG) calculations using our observations and archival $^{12}$CO (1-0), $^{12}$CO(2-1) data, (2) dense gas fraction suggested by HCN to $^{12}$CO (1-0) luminosity ratio, and (3) infrared color. The results show that the molecular gas in the central region is warmer and denser than that of the offset ridges. Dense gas fraction of the central region is similar with that of LIRGs/ULIRGs, while the offset ridges are close to the global average of normal galaxies. The coolest and least dense region is found in a spiral-like structure, which was misunderstood to be part of the southern primary bar in previous low-resolution observations. Star formation efficiency (SFE) changes by ~ 5 times in the inner disk. The variation of SFE agrees with the prediction in terms of star formation regulated by galactic bar. We find a consistency between star-forming region and the temperature inferred by the infrared color, suggesting that the distribution of sub-kpc scale temperature is driven by star formation.

description: A 11 de março de 2020, a Organização Mundial de Saúde (OMS) declarou a existência de uma nova pandemia global. De facto, em 2020 e 2021, os portugueses viveram dois longos momentos de confinamento que produziram uma modificação dos nossos hábitos. Como a comunidade do Instituto Politécnico de Portalegre enfrentou este momento? O consumo de notícias aumentou? Com base nas respostas de um inquérito a toda a comunidade académica do IPP, o presente artigo procura mapear os efeitos da pandemia no consumo de notícias.

description: We perform a Wang-Landau Monte Carlo simulation of a Cu0.5Zn0.5 order-disorder transition using 250 atoms and pairwise atom swaps inside a 5 x 5 x 5 BCC supercell. Each time step uses energies calculated from density functional theory (DFT) via the all-electron Korringa-Kohn- Rostoker method and self-consistent potentials. Here we find CuZn undergoes a transition from a disordered A2 to an ordered B2 structure, as observed in experiment. Our calculated transition temperature is near 870 K, comparing favorably to the known experimental peak at 750 K. We also plot the entropy, temperature, specific-heat, and short-range order as a function of internal energy.

description: Using the Kadanoff-Baym-Keldysh formalism, we employ nonequilibrium dynamical mean-field theory to exactly solve for the nonlinear response of an electron-mediated charge-density-wave-ordered material. We examine both the dc current and the order parameter of the conduction electrons as the ordered system is driven by the electric field. Although the formalism we develop applies to all models, for concreteness, we examine the charge-density-wave phase of the Falicov-Kimball model, which displays a number of anomalous behaviors including the appearance of subgap density of states as the temperature increases. These subgap states should have a significant impact on transport properties, particularly the nonlinear response of the system to a large dc electric field.
