Year: 2019

description: Neste artigo, pretendo apresentar um conjunto de ideias resultantes da abordagem das transformações geométricas, numa superfície plana, a partir das conceções e práticas de futuros professores, no âmbito da unidade curricular de Transformações Geométricas, do mestrado em Ensino do 1.º ciclo do ensino básico e de matemática e ciências naturais no 2.º ciclo do ensino básico, Escola Superior de Educação e Comunicação, Universidade do Algarve, integrando exemplos de simetrias, em rosáceas, frisos e padrões na natureza e na arte. A metodologia utilizada na recolha e análise dos dados assume uma natureza interpretativa, com recurso aos registos áudio de todas as aulas, às tarefas matemáticas realizadas, às notas do professor e às produções dos futuros professores, no contexto das aulas e dos trabalhos realizados autonomamente. Os dados apontam para uma redescoberta, por parte dos futuros professores, do conceito de simetria, envolvendo diversos tipos de simetria, em rosáceas, frisos e padrões, incluindo a análise de situações menos comuns como segmentos de reta, rosáceas distintas da forma circular, frisos e padrões com reflexões deslizantes encobertas. O reforço do conhecimento matemático resultou de uma diversidade de exemplos de simetrias, em rosáceas, frisos e padrões, através de um novo olhar matemático sobre a natureza e a arte, tendo em atenção o trabalho em sala de aula com alunos do 2.º ciclo do ensino básico.

description: We examine the stability of the mass hierarchy in hidden-sector supergravity theories. We show that a quadratically divergent tadpole can appear at two loops, even in minimal supergravity theories, provided the theory has a gauge- and global-symmetry singlet with renormalizable couplings to the visible fields. This tadpole can destabilize the hierarchy. We also find a quadratically divergent two-loop contribution to the field-dependent vacuum energy. This result casts doubt on the efficacy of the "LHC mechanism" for controlling quadratic divergences. We carry out the two-loop calculation in a manifestly supersymmetric formalism, and explain how to apply the formalism in the presence of supersymmetry breaking to derive radiative corrections to the supersymmetric and soft supersymmetry-breaking operators. Our approach greatly simplifies the calculation and guarantees consistency of our results with the underlying supergravity framework.

Year: 2019

description: O Curso de Licenciatura em Educação Básica (LEB) da Escola Superior de Educação e Comunicação da Universidade do Algarve oferece aos estudantes do 3.º ano, distintas unidades curriculares (UC) opcionais. A UC de Literacia Científica é uma dessas opções que tem vindo a ser lecionada de um modo diferenciado e inovador, contrastando com as premissas de cariz mais tradicional, fomentando aprendizagens ativas, baseadas no paradigma socioconstrutivista e colocando o aluno no cerne da aprendizagem e o professor como facilitador dessas mesmas aprendizagens. O conceito de Literacia Científica (LC) tem tido primordial destaque na investigação educacional dos últimos anos, principalmente no que concerne à sua importância para as crianças que frequentam as primeiras etapas escolares. O facto de as crianças contactarem, desde cedo, com elementos básicos da Ciência, permitir-lhes-á, mais tarde, compreenderem e atuarem sobre o entorno natural e social. Cabe, pois aos futuros professores e educadores fomentarem o gosto por aprender Ciência, de modo a que se possa ter, no futuro, cidadãos cientificamente literatos. Este estudo de um contexto particular, que decorreu no ano letivo 2017/2018, alicerça-se numa metodologia qualitativa e tem como principal propósito averiguar quais as perceções dos estudantes do 3.º ano da LEB, acerca: da seleção da UC de LC; da metodologia adotada nesta UC; e da sua implementação, planificação e avaliação. Os resultados sugerem que os estudantes apontam a Literacia Científica como uma UC dinâmica, onde tiveram voz ativa na sua aprendizagem, proporcionando o desenvolvimento de competências de várias índoles e a construção do seu próprio conhecimento.

description: We study the maximal displacement and related population for a branching Brownian motion in Euclidean space in terms of the principal eigenvalue of an associated Schrödinger type operator. We first determine their growth rates on the survival event. We then establish the upper deviation for the maximal displacement under the possibility of extinction. Under the non-extinction condition, we further discuss the decay rate of the upper deviation probability and the population growth at the critical phase.

description: We study at finite temperature the energy-momentum tensor $T_{μν}(x)$ of (i) a scalar field in arbitrary dimension, and (ii) a spinor field in 1+1 dimensions, interacting with a static background electromagnetic field. $T_{μν}$ separates into an UV divergent part $T_{μν}^{sea}$ representing the virtual sea, and an UV finite part $T_{μν}^{plasma}$ describing the thermal plasma of the matter field. $T_{μν}^{sea}$ remains uniform in the presence of a \underbar{uniform} electric field $\vec E$, while $T_{μν}^{plasma}$ becomes a periodic function with period $Δx=2πT/E$ in the direction parallel to $\vec E$. A related periodicity is found for a uniform static magnetic field if one spatial direction perpendicular to the magnetic field is compactified to a circle.

description: A promoção e o desenvolvimento de competências essenciais na escola e na vida podem ser consideradas práticas de ensino-aprendizagem inovadoras. Estas, ao fomentarem explícita e intencionalmente o pensamento crítico, a criatividade, a colaboração e a comunicação – os quatro pilares da aprendizagem significativa –, podem ajudar a promover tais competências. Neste artigo, partilham-se estratégias didático-pedagógicas a serem utilizadas nas práticas das Ciências no 2.º Ciclo do Ensino Básico, para a identificação, análise e desconstrução de conceções alternativas de Ciências, no quadro mais amplo de uma abordagem Ciência-Tecnologia-Sociedade/Pensamento Crítico (CTS/PC). Propõem-se exemplos de tais estratégias (nomeadamente, concept cartoons, participação de cientista convidado, construção de mapa de conceitos e controvérsia sociocientífica), apresentados no contexto de uma sequência didática, da autoria dos autores, adaptados às aprendizagens essenciais deste ciclo de estudo. Após escolhido o tema organizador das aprendizagens essenciais da área e ano pretendidos (Ciências Naturais do 5.º ano), a sequência didática foi construída tendo em vista a inclusão de estratégias didático-pedagógicas especificamente orientadas à promoção do pensamento crítico dos alunos, para a identificação, análise e desconstrução de conceções alternativas de Ciências, nomeadamente no que concerne fatores que colocam em perigo a biodiversidade local, que medidas de prevenção podem ser tomadas e como podem os alunos posicionar-se criticamente face a esses temas. Através de tais práticas pedagógicas inovadoras, os professores podem inovar na sala de aula e criar impactes dentro e fora dela.

A grid-overlay finite difference method for the fractional Laplacian on arbitrary bounded domains

description: A grid-overlay finite difference method is proposed for the numerical approximation of the fractional Laplacian on arbitrary bounded domains. The method uses an unstructured simplicial mesh and an overlay uniform grid for the underlying domain and constructs the approximation based on a uniform-grid finite difference approximation and a data transfer from the unstructured mesh to the uniform grid. The method takes full advantages of both uniform-grid finite difference approximation in efficient matrix-vector multiplication via the fast Fourier transform and unstructured meshes for complex geometries and mesh adaptation. It is shown that its stiffness matrix is similar to a symmetric and positive definite matrix and thus invertible if the data transfer has full column rank and positive column sums. Piecewise linear interpolation is studied as a special example for the data transfer. It is proved that the full column rank and positive column sums of linear interpolation is guaranteed if the spacing of the uniform grid is smaller than or equal to a positive bound proportional to the minimum element height of the unstructured mesh. Moreover, a sparse preconditioner is proposed for the iterative solution of the resulting linear system for the homogeneous Dirichlet problem of the fractional Laplacian. Numerical examples demonstrate that the new method has similar convergence behavior as existing finite difference and finite element methods and that the sparse preconditioning is effective. Furthermore, the new method can readily be incorporated with existing mesh adaptation strategies. Numerical results obtained by combining with the so-called MMPDE moving mesh method are also presented.

description: Neutrino telescopes provide strong sensitivity to sterile neutrino oscillations through matter-enhanced oscillation, occurring in the few TeV energy range for eV$^{2}$-scale neutrino mass-squared splittings. Prior searches have focused on $ν_μ$ disappearance, which has a particularly strong sensitivity to the mixing angle $θ_{24}$ via $ν_μ\rightarrowν_s$ transitions. Nowadays, the $ν_μ\rightarrowν_e$ and $ν_μ\rightarrowν_τ$ appearance channels have been considered less promising at neutrino telescopes, due in part to the much smaller target volume for cascades relative to tracks. This work explores the detectability of these signatures at neutrino telescopes given present constraints on sterile neutrino mixing, and as an example, forecasts the sensitivity of the IceCube Neutrino Observatory to the mixing angles $θ_{14}$, $θ_{24}$, and $θ_{34}$ in the 3+1 sterile neutrino model using the cascade channel with ten years of data. We find that $ν_τ$ appearance signatures consistent with the existing IceCube $ν_μ$ disappearance best-fit point are discoverable for values of $θ_{34}$ consistent with world constraints, and that the sterile neutrino parameters favored by the BEST and gallium anomalies are expected to be testable at the 95\% confidence level.

description: Analytical approximations are commonly employed in the initial trajectory design phase of a mission to rapidly explore a broad design space. In the context of an asteroid deflection mission, accurately predicting deflection is crucial to determining the spacecraft's trajectory that will produce the desired outcome. However, the dynamics involved are intricate, and simplistic models may not fully capture the system's complexity. This study assesses the precision and limitations of analytical models in predicting deflection, comparing them to more accurate numerical simulations. The findings reveal that encounters with perturbing bodies, even at significant distances (a dozen times the radii of the sphere of influence of the perturbing planet), can markedly disturb the deflected asteroid's trajectory, resulting in notable disparities between analytical and numerical predictions. The underlying reasons for this phenomenon are explained, and provisional general guidelines are provided to assist mission analysts in addressing such occurrences. By comprehending the impact of shallow encounters on deflection, this study equips designers with the knowledge to make informed decisions throughout the trajectory planning process, enhancing the efficiency and effectiveness of asteroid deflection missions.

description: We study the most promising signals of Constrained Minimal Supersymmetry detectable at a luminosity upgraded 2 TeV Fermilab Tevatron collider. Using a full event-level Monte Carlo based on Pythia/Jetset, we simulate the trilepton signal examining in detail the effect of constraints on the parameter space. We also simulate the monolepton and dilepton signals, the missing E_T + jets signal, and the signals of stop production in supersymmetry all with full Standard Model backgrounds with realistic detector cuts. We find that large fractions of parameter space can be probed (or eliminated if no signal is found), but mass limits on charginos and neutralinos are not possible based solely on the trilepton signal. Detection efficiencies depend strongly on supersymmetry parameters beyond simply the neutralino and chargino masses; analyses (experimental or theoretical) that do not include this will draw misleading conclusions. Finally, we comment on how searches at LEP II will complement searches at Fermilab.

description: We construct a notion of teleparallelization for Newton-Cartan theory, and show that the teleparallel equivalent of this theory is Newtonian gravity; furthermore, we show that this result is consistent with teleparallelization in general relativity, and can be obtained by null-reducing the teleparallel equivalent of a five-dimensional gravitational wave solution. This work thus strengthens substantially the connections between four theories: Newton-Cartan theory, Newtonian gravitation theory, general relativity, and teleparallel gravity.

Prandtl-Batchelor theorem for flows with quasi-periodic time dependence

description: The classical Prandtl-Batchelor theorem (Prandtl 1904; Batchelor 1956) states that in the regions of steady 2D flow where viscous forces are small and streamlines are closed, the vorticity is constant. In this paper, we extend this theorem to recirculating flows with quasi-periodic time dependence using ergodic and geometric analysis of Lagrangian dynamics. In particular, we show that 2D quasi-periodic viscous flows, in the limit of zero viscosity, cannot converge to recirculating inviscid flows with non-uniform vorticity distribution. A corollary of this result is that if the vorticity contours form a family of closed curves in a quasi-periodic viscous flow, then at the limit of zero viscosity, vorticity is constant in the area enclosed by those curves at all times.

description: Planckian behavior has been recently observed in La1.76Sr0.24CuO4 at the pseudogap critical point. The Planckian behavior takes place in an intriguing quantum metallic state at a quantum critical point. Here, the Planckian behavior was simulated with an energy-independent (or flat) and weakly temperature-dependent electron-boson spectral density (EBSD) function by using a generalized Allen's (Shulga's) formula. We obtained various optical quantities from the flat EBSD function, such as the optical scattering rate, the optical effective mass, and the optical conductivity. These quantities are well fitted with the recently observed Planckian behavior. Fermi-liquid behavior was also simulated with an energy-linear and temperature-independent EBSD function. The EBSD functions agree well with the overall doping- and temperature-dependent trends of the EBSD function obtained from the optically measured spectra of cuprate systems, which can be crucial for understanding the microscopic electron-pairing mechanism for high-Tc superconductivity in cuprates.

description: Differential spectra of coherent photon bremsstrahlung in relativistic heavy ion collisions are calculated within various schematic models of the projectile-target stopping. Two versions of the degradation length model, based on a phenomenological deceleration law, are considered. The simple shock wave model is studied analytically. The predictions of these models agree in the soft photon limit, where the spectrum is determined only by the final velocity distribution of charged particles. The results of these models in the case of central Au+Au collisions at various bombarding energies are compared with the predictions of the microscopic transport model UrQMD. It is shown that at the AGS energy the coherent photon bremsstrahlung exceeds the photon yield from $π^0$-decays at photon energies $ω\loo 50$ MeV.

description: In this paper, we assess the state of the art in pedestrian trajectory prediction within the context of generating single trajectories, a critical aspect aligning with the requirements in autonomous systems. The evaluation is conducted on the widely-used ETH/UCY dataset where the Average Displacement Error (ADE) and the Final Displacement Error (FDE) are reported. Alongside this, we perform an ablation study to investigate the impact of the observed motion history on prediction performance. To evaluate the scalability of each approach when confronted with varying amounts of agents, the inference time of each model is measured. Following a quantitative analysis, the resulting predictions are compared in a qualitative manner, giving insight into the strengths and weaknesses of current approaches. The results demonstrate that although a constant velocity model (CVM) provides a good approximation of the overall dynamics in the majority of cases, additional features need to be incorporated to reflect common pedestrian behavior observed. Therefore, this study presents a data-driven analysis with the intent to guide the future development of pedestrian trajectory prediction algorithms.

description: Multi-band observations of the fast radio burst (FRB) 131104 show that this burst may be associated with a gamma-ray transient entitled Swift J0644.5-5111. Follow-up observations for potential X-ray and radio counterparts of FRB 131104/Swift J0644.5-5111 got null results and provided the upper limits of the emission flux at 5.5 GHz, 7.5 GHz, $U$-band, and X-ray band. By assuming this association and using these upper limits, environmental properties (the fraction of energyin a magnetic field $\varepsilon_{\rm B}$ and the number density $n$) of the progenitor system of FRB 131104/Swift J0644.5-5111 were constrained in the context of the standard afterglow model that neglects the non-relativistic effect and jet effect by several groups. In this paper, we adopt a unified afterglow model that takes into account the non-relativistic effect and jet effect and use the upper limits of four bands (5.5 GHz, 7.5 GHz, $U$-band, and X-ray) to obtain more stringent constraints on the parameter space spanned by $\varepsilon_{\rm B}$ and $n$. We thus suggest that FRB 131104/Swift J0644.5-5111 might originate from a black hole-neutron star merger event. Moreover, we calculate multi-band emissions from a kilonova powered by the radioactivity of $r$-process elements synthesized in the ejected neutron-rich material and find that the $U$-band emission from the putative kilonova is significantly lower than the upper limit of the observations.

Publisher: name: Interacções
Year: 2019

description: Este trabalho foi realizado no enquadramento dos objetivos de aprendizagem da unidade curricular Qualidade de Vida do curso de Literacia Digital para o Mercado de Trabalho (LDMT) e concretizado com estudantes do ensino superior com necessidades educativas. O seu objetivo principal é apresentar uma reflexão do processo de aprendizagem dos estudantes durante a aplicação de uma sequência didática sobre alimentação. As evidências recolhidas da participação dos estudantes de LDMT nas diferentes atividades da sequência didática mostram que adquiriram ou aprofundaram conhecimentos sobre a alimentação saudável. Os principais constrangimentos resultaram de os estudantes terem conhecimentos prévios bastante desiguais sobre a alimentação e dificuldades em realizar determinadas tarefas autonomamente. Uma das atividades dessa sequência consistiu na realização de um estudo sobre os hábitos alimentares de uma amostra de estudantes da instituição de ensino superior. Os estudantes de LDMT aplicaram um inquérito a 36 participantes para quantificar os tipos de alimentos ingeridos pelos inquiridos ao almoço. O objetivo foi identificar os hábitos alimentares saudáveis e os erros alimentares. Os resultados foram expressos em gráficos. A análise dos resultados mostra que a alimentação dos estudantes ao almoço foi diversificada, tendo em conta os grupos da roda dos alimentos, mas apresentou alguns erros alimentares associados ao consumo de alimentos processados, fast-food, bolos e doces. Este estudo, ao implicar o envolvimento dos estudantes de LDMT em algumas etapas do processo de realização de uma investigação, permitiu que desenvolvessem as suas competências nesta área.

Boundary-Value Problems for the Squared Laplace Operator

Year: 1998

description: The squared Laplace operator acting on symmetric rank-two tensor fields is studied on a (flat) Riemannian manifold with smooth boundary. Symmetry of this fourth-order elliptic operator is obtained provided that such tensor fields and their first (or second) normal derivatives are set to zero at the boundary. Strong ellipticity of the resulting boundary-value problems is also proved. Mixed boundary conditions are eventually studied which involve complementary projectors and tangential differential operators. In such a case, strong ellipticity is guaranteed if a pair of matrices are non-degenerate. These results find application to the analysis of quantum field theories on manifolds with boundary.

O Que é um Problema Matemático?

Publisher: name: Interacções

description: A resolução de problemas no ensino da matemática assume-se como uma capacidade transversal essencial para o desenvolvimento de ideias matemáticas por parte dos alunos, colocando-os a pensar e a desenvolver o seu raciocínio matemático. Neste contexto, o presente artigo tem como objetivo apresentar as conceções de problema matemático de quatro alunos do 4.º ano de escolaridade, antes e após a implementação de uma sequência didática baseada na formulação de problemas. Tendo presente este objetivo, optou-se por uma metodologia qualitativa, através do estudo de caso, recorrendo-se a um questionário como instrumento de recolha de dados. Os resultados sugerem que, inicialmente, os alunos definiram problema matemático como sendo um enunciado cuja resolução implica o recurso a cálculos matemáticos, que tenham uma pergunta e que não tenham mais do que uma solução ou solução nenhuma. Esta realidade parece sugerir que estes alunos estão mais familiarizados com um tipo de problema matemático - os problemas de cálculo - em detrimento de outro tipo de problemas que desenvolvem importantes capacidades matemáticas. Contudo, a implementação da sequência didática baseada na formulação de problemas, parece ter influenciado as conceções de problema matemático dos alunos, uma vez que os alunos passaram a dar mais relevância à existência de um contexto no enunciado e ao facto dos problemas terem de ser desafiantes, destacando-se a importância da formulação de problemas nas práticas em sala de aula, com vista ao desenvolvimento de capacidades matemáticas por parte dos alunos.

description: This article is aimed at proposing a generalization of the Ross-Macdonald model for the transmission of Vector-borne diseases in which human-to-human contagions are also considered. We first present this generalized model by formulating a mean field theory, checking its validity by comparing to numerical simulations. To make the premises of our model more realistic, we adapt the mean field equations to the case in which human contacts are described by a complex network. In this case we are also able to derive an analytical expression for the epidemic threshold. In both the mean-field and network-based models, we estimate the value of the epidemic threshold which corresponds to the boundary between the disease-free and epidemic regimes. The expression of this threshold allows us to discuss the impact that human-to-human contagions have on the spread of vector-borne diseases.

description: Machine learning models may inadvertently memorize sensitive, unauthorized, or malicious data, posing risks of privacy breaches, security vulnerabilities, and performance degradation. To address these issues, machine unlearning has emerged as a critical technique to selectively remove specific training data points' influence on trained models. This paper provides a comprehensive taxonomy and analysis of the solutions in machine unlearning. We categorize existing solutions into exact unlearning approaches that remove data influence thoroughly and approximate unlearning approaches that efficiently minimize data influence. By comprehensively reviewing solutions, we identify and discuss their strengths and limitations. Furthermore, we propose future directions to advance machine unlearning and establish it as an essential capability for trustworthy and adaptive machine learning models. This paper provides researchers with a roadmap of open problems, encouraging impactful contributions to address real-world needs for selective data removal.

description: Near- and mid-IR absorption spectra of endohedral H2@C60+ have been measured using He-tagging. The samples have been prepared using a 'molecular surgery' synthetic approach and were ionized and spectroscopically characterized in the gas phase. In contrast to neutral C60 and H2@C60, the corresponding He-tagged cationic species show distinct spectral differences. Shifts and line splittings in the near- and mid-IR regions indicate the influence of the caged hydrogen molecule on both the electronic ground and excited states. Possible relevance to astronomy is discussed.
