description: Iron oxides and oxyhydroxides are challenging to model computationally as competing phases may differ in formation energies by only several kJ/mol, they undergo magnetization transitions with temperature, their structures may contain partially occupied sites or long-range ordering of vacancies, and some loose structures require proper description of weak interactions such as hydrogen bonding and dispersive forces. If structures and transformations are to be reliably predicted under different chemical conditions, each of these challenges must be overcome simultaneously, while preserving a high level of numerical accuracy and physical sophistication. Here we present comparative studies of structure, magnetization, and elasticity properties of iron oxides and oxyhydroxides using density functional theory calculations with plane-wave and locally-confined-atomic-orbital basis sets, which are implemented in VASP and SIESTA packages, respectively. We have selected hematite, maghemite, goethite, lepidocrocite, and magnetite as model systems from a total of 13 known iron oxides and oxyhydroxides; and use same convergence criteria and almost equivalent settings in order to make consistent comparisons. Our results show both basis sets can reproduce the energetic stability and magnetic ordering, and are in agreement with experimental observations. There are advantages to choosing one basis set over the other, depending on the intended focus. In our case, we find the method using PW basis set most appropriate, and combine our results to construct the first phase diagram of iron oxides and oxyhydroxides in the space of competing chemical potentials, generated entirely from first principles

description: Several approaches to photonuclear reactions, based on the time-dependent density-functional theory, have been developed recently. The standard linearization leads to the random-phase approximation (RPA) or the quasiparticle-random-phase approximation (QRPA). We have developed a parallelized QRPA computer program for axially deformed nuclei. We also present a feasible approach to the (Q)RPA calculation, that is the finite amplitude method (FAM). We show results of photoabsorption cross sections for deformed nuclei using the QRPA and FAM calculations. Finally, the canonical-basis approach to the time-dependent Hartree-Fock-Bogoliubov method is presented, to demonstrate its feasibility and usefulness.

description: If you search for 'collective behaviour' with your web browser most of the texts popping up will be about group activities of humans, including riots, fashion and mass panic. Nevertheless, collective behaviour is also considered to be an important aspect of observed phenomena in atoms and molecules, for example, during spontaneous magnetization. In your web search, you might also find articles on collectively migrating bacteria, insects or birds; or phenomena where groups of organisms or non- living objects synchronize their signals or motion (think of fireflies flashing in unison or people clapping in phase during rhythmic applause).

Renormalization Group Running of Lepton Mixing Parameters in See-Saw Models with $S_4$ Flavor Symmetry

Year: 2010
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We study the renormalization group running of the tri-bimaximal mixing predicted by the two typical $S_4$ flavor models at leading order. Although the textures of the mass matrices are completely different, the evolution of neutrino mass and mixing parameters is found to display approximately the same pattern. For both normal hierarchy and inverted hierarchy spectrum, the quantum corrections to both atmospheric and reactor neutrino mixing angles are so small that they can be neglected. The evolution of the solar mixing angle $θ_{12}$ depends on $\tanβ$ and neutrino mass spectrum, the deviation from its tri-bimaximal value could be large. Taking into account the renormalization group running effect, the neutrino spectrum is constrained by experimental data on $θ_{12}$ in addition to the self-consistency conditions of the models, and the inverted hierarchy spectrum is disfavored for large $\tanβ$. The evolution of light-neutrino masses is approximately described by a common scaling factor.

description: Dielectric elastomer actuator (DEA) based on dielectric elastomer holds promising applications in soft robotics. Compliant electrodes with large stretchability and high electrical conductivity are the vital components for the DEAs. In this study, a type of DEA was developed using carbon nanotube/polyvinyl alcohol (CNT/PVA) hydrogel electrodes. The CNT/PVA hydrogel electrodes demonstrate a stretchability up to 200% with a small relative resistance change of approximately 1.2, and a self-healing capability. The areal strain of the DEA based on the CNT/PVA hydrogel electrodes is more than 40%, much higher than the ones based on pure PVA electrodes.

description: O objetivo do estudo foi analisar o efeito de 6 semanas de treino de força constituído por diferentes protocolos no desenvolvimento da força máxima (1RM: repetição máxima) dos membros superiores e inferiores em alunos do 2.º ano da Licenciatura em Desporto da ESE/IPS no ano letivo 2014/15. Os diferentes protocolos de treino foram selecionados de forma aleatória (treino concorrente ou em circuito, força explosiva ou hipertrofia muscular). Os estudantes (n=30; 1.68±0.09 m, 67.00±19.20 kg e IMC 25.00±3.00 kg/m2) foram organizados em grupos de 2 elementos, tendo realizado o programa de treino uma vez por semana com prescrição estruturada e organizada, de acordo com as referências científicas da metodologia de treino aplicada aos diferentes protocolos executados. Recorreu-se à avaliação da força máxima no exercício de supino (1RMSUP) e na prensa de pernas (1RMPR) antes e após as 6 semanas de treino. Embora o número de alunos distribuídos pelos diferentes protocolos de treino não permita uma comparação equitativa entre os grupos, observamos que maioritariamente a força máxima ao nível dos membros superiores antes e após os programas de intervenção é 10% inferior à força total o obtida nos membros inferiores, no entanto, todos s grupos melhoraram significativamente entre o pré e o pós-teste (P

description: Topic of the final qualification work: "Development of a low-noise amplifier for determining low-frequency sources of noise in a microwave bipolar transistor."Â This work is aimed at developing a circuit of a measuring setup for isolating low-frequency noise sources of a microwave bipolar transistor with a heterojunction. Various methods for measuring low-frequency noise were considered. On the basis of one of the methods, a scheme of the measuring setup was developed. For this setup, two LNAs were developed, their sensitivity was evaluated, and low-frequency noise measurements were modeled using the developed setup, from which the measurement error was estimated and the PSD of low-frequency noise of the measured transistor was estimated.

description: O objetivo do presente estudo foi avaliar a motivação para o envolvimento em atividades desportivas (AD) em função do género. A amostra foi composta por 36 clientes de um ginásio divididos por género (n=18 masculinos 34.83 ± 17.16, idade; n=18 femininos 29.72 ± 11.24 idade). Foi utilizado o Questionário de Mo-tivação para as Atividades Desportivas (QMAD) (Serpa e Frias, 1990). Após uma informação inicial dos propósitos da investigação e a obtenção do consentimento por parte dos encarregados de educação dos indivíduos menores foram aplicados os questionários, sendo solicitado que respondessem de forma sincera e sendo garantindo o anonimato e a confidencialidade das respostas Os questionários foram aplicados antes dos treinos de modo a evitar diferentes estados emocionais (fadiga, cansaço, motivação) pela equipa de investigação supervisionada por um especialista em Ciências do Desporto. Observaram-se diferenças significativas entre géneros nos fatores “estatuto”, “competição” e “afiliação geral”, com os homens a evidenciarem valores significativamente diferentes (superiores) das mulheres nestes fatores específicos, o que se relaciona com uma motivação mais centrada no ego, na motivação extrínseca e na visibilidade. Estudos futuros de-vem ser conduzidos nesta temática uma vez que é fundamental compreender os motivos que conduzem os praticantes à prática de AD no sentido de procurar que as atividades vão ao encontro do público-alvo e este adira às mesmas e se man-tenha envolvido e motivado ao longo do tempo.

description: Este estudo teve como objetivo comparar os desempenhos dos atletas de diferen-tes escalões etários e dos dois géneros, em Campeonatos do Mundo de Natação masters em dois períodos (2006-2010 e 2008-2012) verificando a possível influ-ência que a idade e o género poderão ter nos desempenhos dos indivíduos. Proce-deu-se à análise dos resultados dos nadadores masters obtidos na página oficial da internet da Federação Internacional de Natação Amadora (FINA, www.fina.org), tendo como critério os dez primeiros classificados das provas de 50, 100, 200, 400 e 800 metros (estilo livre) desde o Campeonato do Mundo de 2006 ao de 2012, sendo os escalões etários estudados 25-29, 35-39, 45-49 e 55-59 anos de idade, amplitudes temporais de dez anos. Concluiu-se que os 49 anos de idade parecem representar uma fronteira nas capacidades funcionais, e, por consequência, no desempenho desportivo e que o género dos nadadores masters relaciona-se com o desempenho em diferentes distâncias de nado.

description: Neste texto apresentam-se os resultados finlandeses no PISA, as suas eventuais causas e as reações que provocaram no sistema educativo e na sociedade. Estes resultados são depois comparados com os resultados portugueses no PISA e com os resultados de ambos os países no PIRLS. Constata-se, que a Finlândia e Portugal têm desempenhos opostos nestes estudos internacionais, mas também inversos. Este facto, aliado a um estudo da Universidade do Porto, permitem questionar a validade universal do PISA.

description: Na história da educação de infância e na sua implementação em Portugal, figuram factos históricos que remontam aos primeiros cuidados prestados às crianças, exclusivamente destinados à figura feminina. Teresa de Matos e Francisco paixão, com onze e trinta e um anos de prática docente, respetivamente, educadores de infância com experiências diferenciadas, construíram os seus percursos académicos e profissionais em contacto direto com as dificuldades, os desafios, as conquistas e algumas surpresas, inerentes à sua condição e visão de género. Destacando alguns estudos e pesquisas relacionadas com o homem como educador de infância mostram, em discurso direto, a forma como encaram a educação, como a testemunham e como são vistos enquanto pares num meio essencialmente feminino.

description: O presente artigo é a narrativa que traduz uma reflexão prático-teórica sobre um projeto desenvolvido numa sala com 23 crianças com 5 anos de idade, pertencente ao Colégio do Vale em Almada, cujo corpo docente tem uma longa prática pedagógica desenvolvida segundo as perspetivas do Movimento da Escola Moderna. Na introdução são expostas as principais orientações que guiam a nossa prática pedagógica, e nomeadamente é elucidado o conceito de projeto que nos conduziu à conceção de um objetivo a atingir, a partir da questão encontrada “Como é que nascem os bebés?”, interesse que foi manifestado durante o Acolhimento em Conselho, onde as crianças mostraram interesse em descobrir a resposta essa questão, o que deu origem a um Projeto de Estudo. Posteriormente, é descrito o contexto pedagógico, no que se refere à organização das rotinas e dos espaços. No capítulo seguinte são apresentadas as fases que constituíram o projeto, a saber: a definição do problema; a planificação e lançamento do trabalho; a sua execução; a sua divulgação e a sua avaliação. O artigo termina com as considerações finais em que são tecidos comentários relativamente ao balanço final que fazemos deste projeto.

description: We present the historic photographic light curves of three little known Blazars (two BL Lacs and one FSRQ), BZB J1058+5628, BZQ J1148+5254 and BZB J1209+4119 spanning a time interval of about 50 years, mostly built using the Asiago plate archive. All objects show evident long-term variability, over which short-term variations are superposed. One source, BZB J1058+5628, showed a marked quasi-periodic variability of 1 mag on time scale of about 6.3 years, making it one of the few BL Lac objects with a quasi-periodic behavior.

Single-Photon Absorption in Coupled Atom-Cavity Systems

description: We show how to capture a single photon of arbitrary temporal shape with one atom coupled to an optical cavity. Our model applies to Raman transitions in three-level atoms with one branch of the transition controlled by a (classical) laser pulse, and the other coupled to the cavity. Photons impinging on the cavity normally exhibit partial reflection, transmission, and/or absorption by the atom. Only a control pulse of suitable temporal shape ensures impedance matching throughout the pulse, which is necessary for complete state mapping from photon to atom. For most possible photon shapes, we derive an unambiguous analytic expression for the shape of this control pulse, and we discuss how this relates to a quantum memory.

Leveraging the light-matter interaction in angle-resolved photoemission spectroscopy
Creators: name: Day, Ryan Patrick
Publisher: name: University of British Columbia
Year: 2020

description: The light-matter interaction is central to the photoemission process, with an ultraviolet photon providing the necessary impulse required to eject those electrons which we collect in an effort to understand the electronic structure of matter. As such, selection rules impose constraints on those electronic orbits to which one is sensitive. Photoemission-based techniques then present an opportunity to access information beyond spectroscopic characterization of a material's level structure; an orbital description of the underlying wavefunctions is also viable. We present here a numerical scheme within which such information can be garnered, with specific application to several experiments on candidate materials. The Fe-based superconductors are an ideal platform for application of this methodology. The electronic structure is characterized by a large number of closely spaced, moderately correlated states. The competition and cooperation between several competing energy scales pose a considerable challenge for both theory and experiment. The unique sensitivity to both spin and orbital degrees of freedom which photoemission provides therefore allow for a comprehensive exploration of the various energy scales in these compounds. Taking advantage of this sensitivity, we have mapped the momentum and energy dependence of spin-orbit entanglement in representative compounds, FeSe and LiFeAs. Despite the surface sensitivity which inhibits access to the crystal bulk in photoemission, there is a strong inclination to assert a correspondence between the bulk electronic structure, and that measured experimentally, a contentious claim which is frequently the cause of misinterpretation. We explore the surface issue in detail, and discover an interference mechanism which provides justification for the unanticipated success of valence-band photoemission in quasi two-dimensional materials. The surface issue is of specific relevance to the Fe-superconductors, where certain orbitals exhibit significant dispersion perpendicular to the surface. We examine the canonical Fe-superconductor LiFeAs, wherein a confluence of three-dimensional dispersion, spin-orbit coupling, and surface states have conspired to preclude identification of the low-energy electronic structure. We combine detailed photon-energy dependent measurements with results from a slab-projected model to unambiguously identify the three-dimensional Fermi surface of this material.

A educação para a criatividade no ensino superior de música: o caso da formação de compositores
Creators: name: Vasconcelos, António
Publisher: name: Medi@ções
Year: 2014

description: No âmbito da educação para a criatividade e para o desenvolvimento autónomo, a formação desenvolvida no ensino superior de música com vista à criação de uma personalidade artística envolve um conjunto diferenciado de processos e procedimentos situados entre diferentes mundos musicais: técnicos, estéticos, sociais e culturais. Da mesma forma, combina a tradição e a inovação em que, partindo dos sujeitos individuais e de sujeitos institucionais, se estabelece uma rede diferenciada e complexa de interdependências colaborativas na procura e no desenvolvimento da singularidade artística e de um trabalho simultaneamente autónomo e conectivo. Partindo de um conjunto de entrevistas a professores de composição do ensino superior de música que exercem simultaneamente a atividade criativa, este texto pretende apresentar e discutir um conjunto de indicadores que potenciam o desenvolvimento da autonomia pessoal e criativa, num quadro de interligações múltiplas. Defende-se a ideia de que a construção da autonomia através da educação para a criatividade se inscreve num contexto formativo complexo, multi-situado, multi-modal e multi-referencial e que, esta via, se afigura como um instrumento potenciador do desenvolvimento de uma educação transformadora e emancipatória.
