description: Charge density wave, or CDW, is usually associated with Fermi surfaces nesting. We here report a new CDW mechanism discovered in a 2H-structured transition metal dichalcogenide, where the two essential ingredients of CDW are realized in very anomalous ways due to the strong-coupling nature of the electronic structure. Namely, the CDW gap is only partially open, and charge density wavevector match is fulfilled through participation of states of the large Fermi patch, while the straight FS sections have secondary or negligible contributions.

Comparative responses of black spruce and jack pine seedlings to interspecific competition

description: Competition from non-crop vegetation decreases the productivity of conifer plantations across Canada. The objectives of this research were: (1) to develop reliable indices of perennial, interspecific competition; (2) to compare the responses of black spruce and jack pine seedlings to tree and brush competition in northern Ontario; and (3) to identify the silvicultural implications of the responses. An examination of potential components of a competition index considered measures based on hemispherical photographs, fractal geometry, stand maps, and mensurational data from 360 seedling-centred plots for each of the two crop species. Reliable competition indices should be simple formulations which include horizontal and vertical dimensions and which express the amount of competition relative to the size of the seedling. The optimum index was found to be the area of competing canopy on hemispherical photographs, relative to the seedling leaf area. An alternate index, requiring no elaborate equipment, was the sum of the competing stem volumes (relative to the seedling stem volume) of the largest competitor in each quadrant surrounding the seedling. Comparisons of crop tree responses were made using functional growth analysis, replacing the conventional time axis with a competition axis. The relationship between growth and competition was adequately modelled with a power exponential composite function. Jack pine and bare root stock of both species maintained superior growth despite greater sensitivities to competition, compared to black spruce and container stock, respectively. Thus, jack pine or bare root stock of black spruce would outperform the alternatives if tending were delayed, but competition should be removed in all cases to capture the maximum growth potential. The rate of growth decline in response to competition was consistently greatest at the lowest competition levels, indicating that no beneficial effect on growth was provided by a light cover of non-crop vegetation. Allometric analyses indicated that black spruce had a greater morphological plasticity than jack pine. At high competition levels black spruce allocated more biomass to branches and foliage, at the expense of stem and roots. Jack pine demonstrated no such adjustment in allocation pattern, but followed a strategy of stress avoidance through sustained high growth rates.

description: Optimal performance is critical for decision-making tasks from medicine to autonomous driving, however common performance measures may be too general or too specific. For binary classifiers, diagnostic tests or prognosis at a timepoint, measures such as the area under the receiver operating characteristic curve, or the area under the precision recall curve, are too general because they include unrealistic decision thresholds. On the other hand, measures such as accuracy, sensitivity or the F1 score are measures at a single threshold that reflect an individual single probability or predicted risk, rather than a range of individuals or risk. We propose a method in between, deep ROC analysis, that examines groups of probabilities or predicted risks for more insightful analysis. We translate esoteric measures into familiar terms: AUC and the normalized concordant partial AUC are balanced average accuracy (a new finding); the normalized partial AUC is average sensitivity; and the normalized horizontal partial AUC is average specificity. Along with post-test measures, we provide a method that can improve model selection in some cases and provide interpretation and assurance for patients in each risk group. We demonstrate deep ROC analysis in two case studies and provide a toolkit in Python.

description: We present theoretical transmission spectra of a strongly driven, damped, flux qubit coupled to a dissipative resonator in the ultrastrong coupling regime. Such a qubit-oscillator system, described within a dissipative Rabi model, constitutes the building block of superconducting circuit QED platforms. The addition of a strong drive allows one to characterize the system properties and study novel phenomena, leading to a better understanding and control of the qubit-oscillator system. In this work, the calculated transmission of a weak probe field quantifies the response of the qubit, in frequency domain, under the influence of the quantized resonator and of the strong microwave drive. We find distinctive features of the entangled driven qubit-resonator spectrum, namely resonant features and avoided crossings, modified by the presence of the dissipative environment. The magnitude, positions, and broadening of these features are determined by the interplay among qubit-oscillator detuning, the strength of their coupling, the driving amplitude, and the interaction with the heat bath. This work establishes the theoretical basis for future experiments in the driven ultrastrong coupling regime and their impact to develop novel quantum technologies with superconducting circuits.

description: A compact low-energy and high-intensity X-ray source for radiation biology applications is presented. A laser-induced plasma moves inside a 30 kV diode and produces a beam of 10$^{14}$ electrons at the anode location. An aluminum foil converts a part of the energy of these electrons into X-ray photons which are characterized using filtered imaging plates. The dose that would be deposited by these X-ray photons in C. elegans larvae is calculated from Geant4 simulations. It can be set to a value ranging between 10 $μ$Gy and 10 mGy per laser shot by simply changing the aluminum foil thickness and the diode voltage. Therefore, this versatile and compact X-ray source opens a new path to explore the radiation effects induced by dose rates varying over several orders of magnitude.

description: We present a brief review of the cohomological solutions of self-coupling interactions of the fields in the free Yang-Mills theory. All consistent interactions among the fields have been obtained using the antifield formalism through several order BRST deformations of the master equation. It is found that the coupling deformations halt exclusively at the second order, whereas higher order deformations are obstructed due to non-local interactions. The results demonstrate the BRST cohomological derivation of the interacting Yang-Mills theory.

description: The discovery of MAX phase borides has added a new dimension for research in the materials science community. In this paper, a first-principles study of the newly known MAX phase borides Zr2AB2 (A = In, Tl) has been carried out. The estimated lattice constants and volumes of the unit cell are found to be consistent with previous study. The dynamical and mechanical stability of the titled compounds have been checked. Fundamental insights into the stiffness constants, elastic moduli, hardness parameters, brittleness and anisotropy indices are presented. The Variation of these mechanical properties was explained based on the Mulliken population analysis and charge density mapping (CDM). The electronic properties have been dealt with by considering electronic band structure and density of states (DOS) which confirmed the metallic nature of Zr2AB2 (A = In, Tl). The lowly dispersive energy bands along the c-direction confirmed anisotropy in conductivity. The analysis of DOS revealed the dominant contribution from Zr-d orbitals to the conductivity with a small contribution from the In/Tl-p states contributing at the Fermi level. The Debye temperature (Theta-D), minimum thermal conductivity (Kmin), Gruneisen parameter and melting temperature (Tm) have been calculated. The higher values of Theta-D and Tm, and lower value of Kmin for Zr2AB2 (A = In, Tl) compared to those of Zr2AC (A = In, Tl). Besides, the specific heat capacities, thermal expansion coefficient, and different thermodynamic potential functions have been calculated. The optical constants have been studied to reveal their possible relevance for application purposes. The reflectivity spectra revealed the applicability of Zr2AB2 (A = In, Tl) as cover materials to diminish the solar heating. The studied physical properties of Zr2AB2 (A = In, Tl) are compared with those of other relevant 212 and 211 MAX phase nanolaminates.

description: Nos últimos anos tem-se assistido a um interesse considerável no desenvolvimento de atletas tomando a noção de preparação desportiva a longo prazo (PDLP) como ferramenta essencial de planeamento (Costa et al., 2016). Parece estar a assistir-se a quebra de recordes mundiais por parte de nadadores que apresentam idades cada vez mais avançadas. Não obstante esta constatação, a investigação nesta matéria permanece escassa. Neste estudo pretende-se verificar uma possível tendência de aumento da longevidade de atletas de nível internacional, mais concretamente proceder a uma análise retrospetiva da idade dos recordistas mundiais, tendo-se selecionado para o efeito o estilo Costas no setor Masculino. Procedeu-se à recolha da informação referentes aos recordes mundiais no sexo masculino obtidos em piscina de 50 m nas diferentes distâncias oficiais na técnica de Costas (50 m, 100 m e 200 m), no período compreendido entre 1949 e 2018. Foram analisados 84 recordes no total. O nome dos nadadores e as idades correspondentes foram recolhidos de uma plataforma digital https://www.swimrankings.net/). A idade cronológica dos nadadores à data da obtenção do recorde mundial foi convertida em idade decimal. Foram calculadas diversas estatísticas descritivas (média, 1 desvio-padrão, variância, quartis). Para analisar a relação entre a idade decimal e a data de obtenção do recorde recorreu-se a uma regressão linear, de modo a analisar a variação cronológica deste parâmetro, calculando-se o coeficiente de correlação linear (R). Confirma-se a tendência para a idade em que se batem os recordes mundiais aumentar ao longo do tempo, tendo-se verificado em resultado da aplicação da regressão linear uma correlação forte e positiva (R = 0,640) entre as idades decimais e as datas de obtenção dos recordes. O nível de significância da correlação foi determinado para p ≤ .05. A tendência de longevidade verificada na natação a nível internacional reforça a necessidade de implementação de um modelo de desenvolvimento desportivo a longo prazo. Para esse efeito, o envolvimento de toda a comunidade técnico-científica da natação nacional é fundamental para promover a longevidade na carreira dos atletas.

description: We investigate how a catastrophic event (modeled as a temporary fall of the reproduction rate) increases the extinction probability of an isolated self-regulated stochastic population. Using a variant of the Verhulst logistic model as an example, we combine the probability generating function technique with an eikonal approximation to evaluate the exponentially large increase in the extinction probability caused by the catastrophe. This quantity is given by the eikonal action computed over "the optimal path" (instanton) of an effective classical Hamiltonian system with a time-dependent Hamiltonian. For a general catastrophe the eikonal equations can be solved numerically. For simple models of catastrophic events analytic solutions can be obtained. One such solution becomes quite simple close to the bifurcation point of the Verhulst model. The eikonal results for the increase in the extinction probability caused by a catastrophe agree well with numerical solutions of the master equation.

description: We search for the charmed pentaquark candidate reported by the H1 collaboration, the Theta_c(3100)^0, in e^+e^- interactions at a center-of-mass (c.m.) energy of 10.58 GeV, using 124~fb-1 of data recorded with the BaBar detector at the PEP-II e^+e^- facility at SLAC. We find no evidence for such a state in the same pD^{*-} decay mode reported by H1, and we set limits on its production cross section times branching fraction into pD^{*-} as a function of c.m. momentum. The corresponding limit on its total rate per e^+e^- -> qqbar event, times branching fraction, is about three orders of magnitude lower than rates measured for the charmed Lambda_c and Sigma_c baryons in such events.

description: A literatura existente sobre o estudo das forças propulsivas em exercícios base de hidroginástica é bastante reduzida. Dos escassos estudos realça-se a comparação das forças aplicadas em diferentes exercícios a diferentes cadências musicais (Santos et al., 2019). Contudo, permanece por esclarecer o comportamento cinético no mesmo exercício básico de hidroginástica, mas usando diferentes estratégias de execução. Foi objetivo deste estudo comparar a força propulsiva durante a flexão do antebraço entre a condição de execução alternada e simultânea. Vinte e três idosas (64,19±7,23 anos de idade; 68,15±9,29 kg de massa corporal; 158±0,07 cm de estatura) cumpriram um protocolo incremental com candências de 105, 120, 135 e 150 batimentos por minuto (bmp), ao ritmo de execução “tempo de água” e com a água ao nível do apêndice xifoide, através da realização da flexão dos antebraços em duas condições de execução: (i) alternada; e (ii) simultânea. Para análise das forças propulsivas recorreu-se a um sistema diferencial de sensores de pressão (Aquanex 4.1, Swimming Technology Research, USA), possibilitando a aquisição de valores de força máxima do membro dominante (FmáxD, N) e não dominante (FmáxND, N). Recorreu-se ao Teste-T para a análise comparativa com uma significância assumida de p≤0,05. Os resultados demostram diferenças na produção de força entre o membro dominante e o membro não dominante maioritariamente na condição de execução simultânea. Na condição alternada este facto não se verifica. Quando comparadas as duas condições de execução nos membros em ação não se detetam quaisquer diferenças em todas as cadências musicais. Quer isto dizer que os instrutores de hidroginástica deverão optar preferencialmente por uma modalidade de execução alternada quando quiserem trabalhar a flexão do antebraço nas suas sessões, de modo a manter a integridade do movimento entre o membro dominante e não dominante.

description: A set of experiments was conducted to synthesize doped and undoped sodium tantalates with carbon and sulfur in energy efficient single-step hydrothermal process. Undoped sodium tantalate nanocubes were synthesized at 140$^\circ$C and doped one at 180$^\circ$C for 12 hours in rich alkaline atmosphere. The sizes of undoped, carbon-doped, and sulfur-doped sodium tantalate nanocubes were 38 nm, 45 nm, and 40 nm, respectively. The morphological, elemental, compositional, structural, thermal, and photophysical properties of as-synthesized doped and undoped sodium tantalate (NaTaO$_3$) were characterized using scanning electron microscope (SEM), energy dispersive x-ray spectroscope (EDS), Raman spectroscopy, X-ray powder diffraction (XRD), thermal gravimetric analysis (TGA), Fourier transform infrared spectrophotometer (FTIR), and UV-vis spectrophotometer. The sulfur doped NaTaO$_3$ shows a higher photocatalytic activity in degradation of methylene blue than carbon doped and the undoped NaTaO$_3$. The band gaps of undoped NaTaO$_3$, carbon doped c-NaTaO$_3$, and sulfur doped s-NaTaO$_3$ were calculated to be 3.94 eV, 3.8 eV, and 3.52 eV, respectively using Tauc plot.

With the same method we establish a sharp lower bound for the slope of trigonal fibrations of even genus and general Maroni invariant; in particular this result proves a conjecture due to Harris and Stankova-Frenkel.

description: A lombalgia é uma queixa comum dos atletas, e o diagnóstico preciso é essencial, pois muitas causas de problemas nas costas podem levar à incapacidade, como tem um grande impacto no rendimento dos nadadores quando ocorrem. O objetivo da revisão sistemática foi avaliar os estudos publicados, definir os fatores de risco que podem predispor um nadador a sofrer de dores lombares. Foram investigadas as bases de dados PubMed, Google Scholar, Web of Sciences e Cochrane Library, e foram usadas as palavras-chave (Low Back Pain) AND (Swimmers). De acordo com os critérios foram encontrados 1225 artigos após as exclusões finais e os artigos repetidos, foram analisados os artigos entre os anos de 2015 a 2020. Foram considerados todos os indivíduos, independentemente da sua idade ou sexo. Dos resultados obtidos, foram considerados 10 artigos elegíveis, com um número aproximado de 688 de participantes, entre jovens, adultos a master. Dos estudos elegíveis, 2 tinham como objetivo programas de exercícios específicos para a zona lombar, outros 2 estudos aplicaram questionários sobre a avaliação das dores lombares, os restantes 6 estudos incidiram sobre a caracterização das dores lombares. Os vários grupos dos estudos eram indivíduos jovens, adultos e mais velhos de ambos os sexos. Os desenhos de estudo de investigação passaram por investigação longitunal e transversal. A evidência quanto às causas das dores em nadadores não é conclusiva, apesar dos resultados desta revisão de estudos. No entanto constatou-se que um programa adequado de reforço muscular ajudará na prevenção das dores lombares (Esser, 2017; Nowotny et al., 2018). De acordo, com a nossa revisão dos estudos concluímos que existem fortes indicadores que as dores lombares estão associadas a problemas técnicos e à falta de reforço muscular da zona lombar. Estes resultados são uma ferramenta para garantir e focar a importância de uma técnica de nado adequada tal como a aplicação de programas de reforço muscular nos nadadores por parte das equipas técnicas. Ainda se colocam dúvidas sobre os benefícios da natação no tratamento de algumas doenças relacionadas com a coluna vertebral, ou até no próprio bem-estar do indivíduo.

description: We report an optical study of transition metal dichalcogenide 2$H$-TaS$_2$ and Na intercalated superconductor Na$_x$TaS$_2$ over a broad frequency range at various temperatures. A clear gap feature was observed for 2$H$-TaS$_2$ when it undergoes a CDW transition. The existence of a Drude component in $σ$$_1$($ω$) below T$_{CDW}$ indicates that the Fermi surface of 2$H$-TaS$_2$ is only partially gapped in CDW state. The spectral evolution of two different Na$_x$TaS$_2$ crystals further confirms that the partial gap structure observed in 2$H$-TaS$_2$ has a CDW origin. The CDW mechanism for 2$H$-TaS$_2$, the competition between CDW and superconductivity in Na$_x$TaS$_2$ system are discussed.

description: We present lattice calculations of the low-lying spectrum of $^{12}$C using a simple nucleon-nucleon interaction that is independent of spin and isospin and therefore invariant under Wigner's SU(4) symmetry. We find strong signals for all excited states up to $\sim 15$~MeV above the ground state, and explore the structure of each state using a large variety of $α$ cluster and harmonic oscillator trial states, projected onto given irreducible representations of the cubic group. We are able to verify earlier findings for the $α$ clustering in the Hoyle state and the second $2^+$ state of $^{12}$C. The success of these calculations to describe the full low-lying energy spectrum using spin-independent interactions suggest that either the spin-orbit interactions are somewhat weak in the $^{12}$C system, or the effects of $α$ clustering are diminishing their influence. This is in agreement with previous findings from {\it ab initio} shell model calculations.

description: As variáveis antropométricas e a força muscular têm sido apontados como fatores determinantes para o rendimento em nadadores jovens (Morais et al., 2013). No entanto, a influência de algumas destas variáveis ainda não é clara na literatura. Com o presente estudo procuramos verificar de que forma as características antropométricas (i.e. altura, massa corporal e envergadura) e a força muscular explosiva poderão influenciar o rendimento desportivo no escalão juvenil, verificando a sua relação com as provas dos 50m e 400m livres. Foram avaliados 184 nadadores (idade: 14.64±0.80 anos; altura: 1.69±0.08m; massa corporal: 58.71±7.87kg),92 do sexo feminino e 92 do sexo masculino. Registaram-se as medidas antropométricas (massa corporal, altura e envergadura) de cada nadador. Seguiu-se a avaliação da força muscular explosiva dos membros inferiores e membros superiores, através do salto horizontal a pés juntos e do lançamento da bola medicinal (3kg), respetivamente. Em dias diferentes, foram realizadas as avaliações do rendimento (tempo) e de variáveis biomecânicas (distância de ciclo, frequência gestual, índice de nado) na prova dos 50m livres e dos 400m livres. Verificou-se uma correlação linear negativa entre a altura (r = -0.64 e r = -0.60, p <0.01), a massa corporal (r = -0.67 e r = -0.60, p <0.01), a envergadura (r = -0.66 e r = -0.58, p<0.01) com o tempo dos 50m livres e dos 400m livres, respetivamente. No que se refere à força muscular, verificou-se uma correlação linear negativa entre o lançamento da bola medicinal (r = -0.80 e r = -0.70, p<0.01) e entre o salto horizontal (r= -0.78 e r = -0.61, p<0.01) e o tempo dos 50m livres e dos 400m livres, respetivamente. Os resultados demonstraram que as características antropométricas (i.e. altura, massa corporal e envergadura) e a força muscular explosiva (i.e., lançamento da bola medicinal e salto horizontal) relacionam-se de uma forma linear e negativa com o rendimento dos 50m e 400m livres em nadadores juvenis.

description: A circular quantum secret sharing protocol is proposed, which is useful and efficient when one of the parties of secret sharing is remote to the others who are in adjacent, especially the parties are more than three. We describe the process of this protocol and discuss its security when the quantum information carrying is polarized single photons running circularly. It will be shown that entanglement is not necessary for quantum secret sharing. Moreover, the theoretic efficiency is improved to approach 100% as almost all the instances can be used for generating the private key, and each photon can carry one bit of information without quantum storage. It is straightforwardly to utilize this topological structure to complete quantum secret sharing with multi-level two-particle entanglement in high capacity securely.

description: This article is the $\mathrm{Z}_l$-version of my paper "Monodromie du faisceau pervers des cycles évanescents de quelques variétés de Shimura simples" in Invent. Math. 2009 vol 177 pp. 239-280, where we study the vanishing cycles of some unitary Shimura variety. The aim is to prove that the cohomology sheaves of this complexe are free so that, thanks to the main theorem of Berkovich on vanishing cycles, we can deduce that the $\mathrm{Z}_l$-cohomology of the model of Deligne-Carayol is free. There will be a second article which will be the $\mathrm{Z}_l$ version of my paper "Conjecture de monodromie-poids pour quelques varités de Shimura unitaires" in Compositio vol 146 part 2, pp. 367-403. The aim of this second article will be to study the torsion of the cohomology groups of these Shimura varieties.

description: We construct supersymmetric $AdS_5\times Σ$ solutions of $D=7$ gauged supergravity, where $Σ$ is a two-dimensional orbifold known as a spindle. These uplift on $S^4$ to solutions of $D=11$ supergravity which have orbifold singularites. We argue that the solutions are dual to $d=4$, $\mathcal{N}=1$ SCFTs that arise from $N$ M5-branes wrapped on a spindle, embedded as a holomorphic curve inside a Calabi-Yau three-fold. In contrast to the usual topological twist solutions, the superconformal R-symmetry mixes with the isometry of the spindle in the IR, and we verify this via a field theory calculation, as well as reproducing the gravity formula for the central charge.

Publisher: name: arXiv
Year: 2011
Subjects: subject: Methodology (stat.ME)

description: We herein introduce a new method of interpretable clustering that uses unsupervised binary trees. It is a three-stage procedure, the first stage of which entails a series of recursive binary splits to reduce the heterogeneity of the data within the new subsamples. During the second stage (pruning), consideration is given to whether adjacent nodes can be aggregated. Finally, during the third stage (joining), similar clusters are joined together, even if they do not descend from the same node originally. Consistency results are obtained, and the procedure is used on simulated and real data sets.

description: A realização de exercícios aquáticos aumentou exponencialmente nas últimas décadas devido aos benefícios dessa prática na saúde e aptidão física1. Essas atividades aquáticas têm sido recomendadas especialmente para pessoas com necessidades especiais, mas também para indivíduos sem qualquer problema associado. Portanto, é importante entender os efeitos dos programas aquáticos sobre o estado de saúde e aptidão física em adultos com e sem patologias. Foi realizada uma revisão sistemática através de uma pesquisa em 3 bases de dados (Web of Science, PubMed e Scopus) até dezembro de 2019. Foram incluídos estudos experimentais, com a aplicação de um programa de treino aquático, comparando (ou não) com um programa realizado em terra e/ou com grupos de controlo com ou sem intervenção. Incluímos estudos que investigaram o efeito dessas atividades em indivíduos sem patologias, mas também em adultos com algumas doenças. As doenças analisadas nos diferentes estudos foram: musculoesqueléticas (fibromialgia e doenças ósseas), doenças cardíacas (doença arterial coronária, insuficiência cardíaca, hipertensão e acidente vascular cerebral), diabetes mellitus, esclerose múltipla e Parkinson. Setenta e oito estudos foram incluídos, trinta para a população sem patologias e quarenta e oito para os indivíduos com alguma doença. A prática de exercício aquático produziu melhorias significativas na maioria das populações. No grupo sem qualquer patologia, os resultados foram notórios sobretudo na força e resistência muscular, equilíbrio e aptidão cardiorrespiratória. Em relação aos indivíduos com alguma doença, os parâmetros que sofreram alterações mais positivas foram a qualidade de vida, aptidão cardiorrespiratória, perceção da dor e equilíbrio. Assim, os programas aquáticos são uma atividade confiável quando a intenção é melhorar indicadores de saúde e aptidão física em adultos patológicos e também em indivíduos sem qualquer doença.

Projecting SPH Particles in Adaptive Environments

Year: 2021
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: The reconstruction of a smooth field onto a fixed grid is a necessary step for direct comparisons to various real-world observations. Projecting SPH data onto a fixed grid becomes challenging in adaptive environments, where some particles may have smoothing lengths far below the grid size, whilst others are resolved by thousands of pixels. In this paper we show how the common approach of treating particles below the grid size as Monte Carlo tracers of the field leads to significant reconstruction errors, and despite good convergence properties is unacceptable for use in synthetic observations in astrophysics. We propose a new method, where particles smaller than the grid size are `blitted' onto the grid using a high-resolution pre-calculated kernel, and those close to the grid size are subsampled, that allows for converged predictions for projected quantities at all grid sizes.

description: We study concepts of stabilities associated to a smooth complex curve together with a linear series on it. In particular we investigate the relation between stability of the associated Dual Span Bundle and linear stability. Our result implies a stability condition related to the Clifford index of the curve. Furthermore, in some of the cases, we prove that a stronger stability holds: cohomological stability. Eventually using our results we obtain stable vector bundles of integral slope 3, and prove that they admit theta-divisors.

Detecting Bosonic Dark Matter with Neutron Stars

description: What if the dark matter-nucleon scattering cross section is too small to be detected by direct detection experiments? It is well known in the literature that some interactions lead to dark matter-nucleon scattering cross sections that can be velocity and momentum suppressed. We show that in the case of bosonic dark matter, neutron star spectroscopy offers a possible detection. Firstly, we discuss the case of scalar dark matter with scalar, pseudoscalar, and vector mediators. Later, we do this exercise for vector dark matter. We show that, depending on the nature of dark matter and the interaction involved, neutron stars can improve the sensitivity on the dark matter-nucleon scattering cross section by orders of magnitude, representing a major step forward in the dark matter siege.

description: A evolução da pandemia provocada pelo novo coronavírus (COVID-19) e as indicações de contingência expressas pela Direção Geral de Saúde, não permitem a realização habitual do 43º Congresso Técnico-Científico da APTN, anteriormente agendado para os dias 1 e 2 de maio de 2020 em Odivelas. Atendendo que a possibilidade de reagendamento em data oportuna para todos os parceiros, oradores e congressistas seria escassa, e mantendo em perspetiva o superior interesse de saúde pública, a APTN em conjunto com a autarquia de Odivelas, promove uma versão digital alternativa - a primeira na história da APTN. Este é um esforço grande para manter a cadência anual de um congresso que se organiza ininterruptamente há 42 anos, sobretudo dos oradores que aceitaram o desafio de partilhar connosco o seu conhecimento e experiência, num formato diferente. O programa será, por isso, muito semelhante à versão inicialmente proposta, contemplando inclusive a possibilidade de submissão de comunicações livres. Tal como já o teríamos referido, a área do treino desportivo terá um especial realce, pelo que contamos com a participação de vários especialistas nacionais e internacionais. Temos a certeza que vai desfrutar. Optamos por um modelo de formação em e-learning pelas suas vantagens de acessibilidade e de conveniência na gestão do tempo dos participantes. Assim, todas as conferências previstas no programa estarão disponíveis para acesso on-line em qualquer momento e durante várias semanas. Para permitir a troca de opiniões, será criado um fórum de discussão sobre cada conferência. Por último, importa salientar que o Congresso anual da APTN também é um momento de convívio e de reconhecimento público, nomeadamente do mérito dos nossos melhores treinadores da época desportiva anterior. Esta finalidade não é possível de garantir cabalmente numa versão digital, pelo que essa cerimónia está para já adiada sine die.

description: We study three methods that prove the positivity of a natural numerical invariant associated to $1-$parameter families of polarized varieties. All these methods involve different stability conditions. In dimension 2 we prove that there is a natural connection between them, related to a yet another stability condition, the linear stability. Finally we make some speculations and prove new results in higher dimension.

Influence of the driving mechanism on the response of systems with athermal dynamics: the example of the random-field Ising model

description: We investigate the influence of the driving mechanism on the hysteretic response of systems with athermal dynamics. In the framework of local-mean field theory at finite temperature (but neglecting thermallly activated processes), we compare the rate-independent hysteresis loops obtained in the random field Ising model (RFIM) when controlling either the external magnetic field $H$ or the extensive magnetization $M$. Two distinct behaviors are observed, depending on disorder strength. At large disorder, the $H$-driven and $M$-driven protocols yield identical hysteresis loops in the thermodynamic limit. At low disorder, when the $H$-driven magnetization curve is discontinuous (due to the presence of a macroscopic avalanche), the $M$-driven loop is re-entrant while the induced field exhibits strong intermittent fluctuations and is only weakly self-averaging. The relevance of these results to the experimental observations in ferromagnetic materials, shape memory alloys, and other disordered systems is discussed.
