description: We investigate creation, manipulation, and steering of entanglement in spin chains from the viewpoint of quantum communication between distant parties. We demonstrate how global parametric driving of the spin-spin coupling and/or local time-dependent Zeeman fields produce a large amount of entanglement between the first and the last spin of the chain. This occurs whenever the driving frequency meets a resonance condition, identified as "entanglement resonance". Our approach marks a promising step towards an efficient quantum state transfer or teleportation in solid state system. Following the reasoning of Zueco et al. [1], we propose generation and routing of multipartite entangled states by use of symmetric tree-like structures of spin chains. Furthermore, we study the effect of decoherence on the resulting spin entanglement between the corresponding terminal spins.

description: O artigo aqui apresentado foca-se numa investigação realizada no contexto do ensino superior online, no decurso do qual se delinearam, aplicaram e avaliaram dois desenhos instrucionais gamificados. Do ponto de vista metodológico, foi usada uma perspetiva inspirada na Design-Based Research, integrando duas fases, com estudantes quase em final de licenciatura, a que se seguiu uma segunda fase com estudantes no início do seu percurso académico. Em qualquer dos casos foi usado um desenho curricular integrando 9 elementos de jogo, embora a mecânica do sistema tenha sofrido alterações, em função dos destinatários e do contexto disciplinar. A recolha de dados foi feita com base na observação participante, em questionários aos estudantes e em entrevistas, que, realizadas posteriormente, procuraram clarificar aspetos advindos da observação ou das respostas aos questionários. Os dados apontam para uma perceção positiva por parte dos estudantes, sobre os desenhos curriculares gamificados que foram implementados, indiciando alguns princípios a ter em conta no desenho instrucional gamificado para o ensino superior online.

The initial conditions of isolated star formation -- IX. Akari mapping of an externally heated pre-stellar core

description: We present observations of L1155 and L1148 in the Cepheus molecular cloud, taken using the FIS instrument on the Akari satellite. We compare these data to submillimetre data taken using the SCUBA camera on the JCMT, and far-infrared data taken with the ISOPHOT camera on board the ISO satellite. All of the data show a relation between the position of the peak of emission and the wavelength for the core of L1155. We interpret this as a temperature gradient. We fit modified blackbody curves to the spectral energy distributions at two positions in the core and see that the central core in L1155 (L1155C) is approximately 2 degrees warmer at one edge than it is in the centre. We consider a number of possible heating sources and conclude that the A6V star BD+67 1263 is the most likely candidate. This star is at a distance of 0.7 pc from the front of L1155C in the plane of the sky. We carry out radiative transfer modelling of the L1155C core including the effects from the nearby star. We find that we can generate a good fit to the observed data at all wavelengths, and demonstrate that the different morphologies of the core at different wavelengths can be explained by the observed 2 degree temperature gradient. The L1148 core exhibits a similar morphology to that of L1155C, and the data are also consistent with a temperature gradient across the core. In this case, the most likely heating source is the star BD197053. Our findings illustrate very clearly that the apparent observed morphology of a pre-stellar core can be highly dependent on the wavelength of the observation, and that temperature gradients must be taken into account before converting images into column density distributions. This is important to note when interpreting Akari and Spitzer data and will also be significant for Herschel data.

description: Pretende-se com este artigo fazer um levantamento, como enquadramento introdutório, na atual sociedade digital, das principais iniciativas da União Europeia e iniciativas nacionais relativamente ao processo que levou à apresentação de propostas associadas à literacia digital e às competências digitais como forma de promover a competitividade de cada país. Seguidamente, passa-se para uma análise crítica e reflexiva acerca do conceito ou dos conceitos subjacentes ao que é entendido como literacia digital e competências digitais através do confronto de perspetivas de diversos autores. Na sequência desta discussão, faz-se uma abordagem à problemática que advém de se ser infoincluído e infoexcluído, com um particular foco nos adultos mais idosos, dado que estes representam os cidadãos com as menores taxas de acesso e de utilização das tecnologias digitais. A constatação da designada fratura digital acarreta consigo uma potencial exclusão social com todas as consequências inerentes. Contudo, é discutido ainda o facto de podermos estar perante uma nova fratura digital que pode ser intergeracional ou intrageracional porque emerge a noção clara de que a literacia digital e as competências digitais associadas só estão presentes se houver uma atitude crítica e reflexiva na utilização e mobilização das tecnologias digitais em detrimento de aspetos mais funcionais ou instrumentais.

description: A continuum model to study the influence of dislocations on the electronic properties of condensed matter systems is described and analyzed. The model is based on a geometrical formalism that associates a density of dislocations with the torsion tensor and uses the technique of quantum field theory in curved space. When applied to two-dimensional systems with Dirac points like graphene we find that dislocations couple in the form of vector gauge fields similar to these arising from curvature or elastic strain. We also describe the ways to couple dislocations to normal metals with a Fermi surface.

description: During its commissioning phase in 2020, the Spectrometer/Telescope for Imaging X-rays (STIX) on board the Solar Orbiter spacecraft observed 69 microflares. The two most significant events from this set (of GOES class B2 and B6) were observed on-disk from the spacecraft as well as from Earth and analysed in terms of the spatial, temporal, and spectral characteristics. We complement the observations from the STIX instrument with EUV imagery from SDO/AIA and GOES soft X-ray data by adding imaging and plasma diagnostics over different temperature ranges for a detailed microflare case study that is focussed on energy release and transport. Spectral fitting of the STIX data shows clear nonthermal emission for both microflares studied here. The deduced plasma parameters from DEM reconstruction as well as spectral fitting roughly agree with the values in the literature for microflares as do the nonthermal fit parameters from STIX. The observed Neupert effects and impulsive and gradual phases indicate that both events covered in this study are consistent with the standard chromospheric evaporation flare scenario. For the B6 event on 7 June 2020, this interpretation is further supported by the temporal evolution seen in the DEM profiles of the flare ribbons and loops. For this event, we also find that accelerated electrons can roughly account for the required thermal energy. The 6 June 2020 event demonstrates that STIX can detect nonthermal emission for GOES class B2 events that is nonetheless smaller than the background rate level. We demonstrate for the first time how detailed multi-instrument studies of solar flares can be performed with STIX.

description: In recent years the increase in childhood ADHD diagnoses has been closely followed by a surge in the prescription of medication for children. The active involvement of children in medical interventions and clinical trials is part of children's rights. It is of the utmost importance that during the course of treatment, children are exercising their rights to informed consent or assent and expressing their views to ensure they are leading personally meaningful lives. The child’s participation in ADHD randomized control trials (RCTs) will be investigated from a child’s rights perspective because the symptoms heavily affect the daytime functioning and quality of life of children. Our objectives include how was the child involved in the consenting process, and was the child directly involved in any of the tools used to measure ADHD, sleep, miscellaneous outcomes, the reporting of adverse events; or was a proxy used. This knowledge will help to determine if the child’s rights are being properly considered in ADHD RCTs as well as to guide future studies in the consenting procedure.

Infrared behavior and infinite-volume limit of gluon and ghost propagators in Yang-Mills theories

description: Lattice studies of the infrared behavior of gluon and ghost propagators are a key probe of confinement scenarios in Yang-Mills theories. However, finite-volume effects become an important issue as the infrared limit is approached. By considering general quantities -- namely an associated susceptibility in the gluon case and properties of the lowest-lying eigenmode of the Faddeev-Popov matrix in the ghost case -- one can derive rigorous upper and lower bounds for the propagators. The bounds allow a better control over the extrapolation of lattice results to the infinite-volume limit. In the case of the gluon propagator, an intuitive statistical argument suggests a precise volume dependence for the bounds. This dependence is nicely confirmed by the lattice data, leading to a finite gluon propagator at zero momentum. At the same time, an enhancement of the ghost propagator in the infrared limit seems unlikely. Our analysis is applied to the case of Landau gauge and SU(2) gauge group, using the largest lattice sizes to date.

description: Este artigo tem como objetivo analisar a atual situação da investigação internacional sobre competências digitais dos professores. Para tal foi realizada um mapeamento sistemático dos artigos recuperados no Portal de Periódico da CAPES entre janeiro e março de 2018. Importa dizer que se optou pela busca no Portal de Periódico da CAPES porque, à época, este permitia o acesso da coleta de dados para este estudo, aos textos completos de artigos de mais de 38.000 publicações periódicas internacionais e 126 bases de dados (a exemplo do Proquest, EBSCO, Science Direct, Emerald, Web of Science e Web of Knowledge) com resumos de documentos em todas as áreas do conhecimento. Optou-se pela regra de exaustividade de Bardin (2011), não sendo definido corte temporal a priori para coleta de dados. Após a coleta de dados, foram recuperados 175 artigos, sendo 37 considerados válidos para compor o corpus deste estudo. As conclusões revelam que o interesse maior dos pesquisadores é sobre as competências digitais docentes de uma maneira ampla e que, por exemplo, pouco se estuda sobre a sua transposição pedagógica. Os achados corroboram estudos anteriores com relação às múltiplas interpretações da compreensão do que seja competência digital. Também há indícios na literatura analisada do uso de mais de uma terminologia, inclusive no mesmo texto, de maneira indistinta e sinonímica, para se referir às competências digitais.

Dynamo efficiency with shear in helical turbulence
Creators: name: Leprovost, Nicolas

Publisher: name: arXiv
Year: 2009
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: To elucidate the influence of shear flow on the generation of magnetic field (the dynamo effect), we study the kinematic limit where the magnetic field does not backreact on the velocity field. By non-perturbatively incorporating the effect of shear in a helically forced turbulence, we show that turbulence intensity and turbulent transport coefficients (turbulent viscosity, $α$ and $β$ effect) are enhanced by a weak shear while strongly suppressed for strong shear. In particular, $β$ is shown to be much more strongly suppressed than $α$ effect. We discuss its important implications for dynamo efficiency, i.e. on the scaling of the dynamo number with differential rotation.

description: Este estudo exploratório, apresentado sob a forma de mapeamento, tem como objetivo analisar estudos em português sobre as seguintes temáticas: Competências digitais, Qualificação e Empregabilidade. Para tal, conjugaram-se estes três termos como descritores no Repositório Científico de Acesso Aberto de Portugal (RCAAP), obtendo-se um corpus que foi analisado num processo analítico-metodológico inspirado no Meta-modelo de Análise e Exploração do Conhecimento Científico® (MAECC®). Com este trabalho preliminar, que pode constituir a base para um projeto a desenvolver com uma equipa mais alargada de investigadores, pretendemos contribuir para a sistematização do conhecimento sobre aquelas áreas, exemplificando uma via para o realizar. Em última instância, esperamos também contribuir para que futuras iniciativas de aquisição e desenvolvimento de competências digitais possam ser melhor (in)formadas.No enquadramento teórico, constatamos que no contexto da atual sociedade, em que as tecnologias colocam novos desafios aos indivíduos, as organizações governamentais têm vindo a definir estratégias políticas, no sentido de melhorar as competências digitais dos seus cidadãos, estabelecendo uma relação direta com a sua qualificação e empregabilidade.Concluímos que a tríade “Competências digitais - Qualificação – Empregabilidade” deve ser uma constante ao longo da vida, pois as evoluções tecnológicas não param de transformar o nosso quotidiano. Mas também é fundamental para a construção de uma sociedade mais justa, inclusiva e sustentável.

description: A participação informada nos processos de decisão coletiva exige melhores níveis educacionais, um leque mais amplo de competências digitais e, naturalmente, o acesso às tecnologias. Na sociedade global digital, este processo faz parte do exercício de uma cidadania informada. A cidadania digital pressupõe a participação mediada pelo acesso e, sobretudo, pelo uso crítico das tecnologias digitais, nos processos de decisão social. Em estreita ligação com a cidadania digital encontra-se a literacia digital. Entendida numa perspetiva mais ampla do que a literacia tecnológica, supõe o desenvolvimento de competências fundamentais que contrariam a exclusão social e, por consequência, representam um valioso mecanismo para o seu combate, especialmente em grupos sociais em risco. Por sua vez, as competências digitais fazem parte das competências essenciais da educação ao longo da vida, estando diretamente relacionadas com os conceitos de cidadania digital e participação democrática. No presente artigo, começamos por analisar os conceitos de cidadania digital, literacia digital e competências digitais para o séc. XXI, bem como as relações entre estes conceitos. Posteriormente, são apresentados dados parciais relativos a uma investigação, em curso, sobre programas digitais como via de empoderamento, no Alentejo e no País Basco. Como conclusão genérica, assinalam-se as perspetivas dos monitores sobre as modificações de hábitos dos utilizadores dos Espaços de Acesso à Internet e dos Centros KZgunea.

title: Studies on the stereoselective synthesis of functionalized quaternary stereocenters and E-3-(arylmethylidene)-5-(alkyl/aryl)-2(3H)-Furanones
Creators: name: Muthusamy, Gopinathan
Publisher: name: Memorial University of Newfoundland
Year: 2019

description: An enantioselective synthesis of isolated acyclic quaternary stereocenters was achieved using metal-catalyzed Gosteli-Claisen rearrangements of allyl vinyl ethers. A concise synthesis of 2-t-butoxycarbonyl allyl vinyl ethers by regioselective Petasis methylenation and stereoselective Suzuki-Miyaura cross-coupling reactions of iodoallyl t-butyl oxalates was developed. Ethers with a terminally unsubstituted vinyl group and a terminally disubstituted allyl portion are readily accessible by this method. In addition to the metal-catalyzed Gosteli-Claisen rearrangements, organocatalytic variant of the Gosteli-Claisen rearrangement was investigated. A modular synthesis of several new, chiral cyclic phosphoramide-based, thioureas, formamidines and thiosemicarbazides was developed and these phosphoramides were examined for their ability to catalyze the Gosteli-Claisen rearrangement of a selected allyl vinyl ether. A variety of E-3-(arylidene)-5-(alkyl/aryl)-2(3H)-furanones were synthesized by employing regioselctive addition of -aryl acrylic acids with iodoacetylenes and subsequent intramolecular Heck reaction of Z-acyloxy iodo alkenes. The approach was applied in a formal synthesis of the naturally occurring kinase inhibitor BE-23372M.

description: We report measurements of the absolute energies of the hyperfine components of the $12s \ ^2S_{1/2}$ and $13s \ ^2S_{1/2}$ levels of atomic cesium, $^{133}$Cs. Using the frequency difference between these components, we determine the hyperfine coupling constants for these states, and report these values with a relative uncertainty of $\sim$0.06 %. We also examine the hyperfine structure of the $11d \ ^2D_{J}$ ($J=3/2, 5/2$) states, and resolve the sign ambiguity of the hyperfine coupling constants from previous measurements of these states. We also derive new, high precision values for the state energies of the $12s \ ^2S_{1/2}$, $13s \ ^2S_{1/2}$ and $11d \ ^2D_{J}$ states of cesium.

The MIMO antenna is built on a FR4 substrate with a dielectric constant of 4.4 and a thickness of 1.6 mm, and it is designed using the ANSYS HFSS software program. This design focuses on optimizing radiation patterns while remaining compact and simple to fabricate. The proposed antenna has a return loss of below -20 dB, VSWR < 1.5, an axial ratio of < 3dB. The simulation results illustrate how well the MIMO antenna effectively performs for SAR applications, such as vegetation monitoring, soil moisture, GPS, and disaster management.

description: Let $Ω$ be an open subset of $\Ri^d$ and $H_Ω=-\sum^d_{i,j=1}\partial_i c_{ij} \partial_j$ a second-order partial differential operator on $L_2(Ω)$ with domain $C_c^\infty(Ω)$ where the coefficients $c_{ij}\in W^{1,\infty}(Ω)$ are real symmetric and $C=(c_{ij})$ is a strictly positive-definite matrix over $Ω$. In particular, $H_Ω$ is locally strongly elliptic. We analyze the submarkovian extensions of $H_Ω$, i.e. the self-adjoint extensions which generate submarkovian semigroups. Our main result establishes that $H_Ω$ is Markov unique, i.e. it has a unique submarkovian extension, if and only if $\capp_Ω(\partialΩ)=0$ where $\capp_Ω(\partialΩ)$ is the capacity of the boundary of $Ω$ measured with respect to $H_Ω$. The second main result establishes that Markov uniqueness of $H_Ω$ is equivalent to the semigroup generated by the Friedrichs extension of $H_Ω$ being conservative.

description: We compute the conservative dynamics of non-spinning binaries at fourth Post-Minkowskian order in the large-eccentricity limit, including both potential and radiation-reaction tail effects. This is achieved by obtaining the scattering angle in the worldline effective field theory approach and deriving the bound radial action via analytic continuation. The associated integrals are bootstrapped to all orders in velocities through differential equations, with boundary conditions in the potential and radiation regions. The large angular momentum expansion captures all the local-in-time effects as well as the trademark logarithmic corrections for generic bound orbits. We briefly discuss strategies to extend the full result to the case of small eccentricities, as well as the inclusion of memory terms. Agreement is found in the overlap with the state-of-the-art in Post-Newtonian theory.

description: We study the flavor-changing quark-graviton vertex that is induced at the one-loop level when gravitational interactions are coupled to the standard model. Because of the conservation of the energy-momentum tensor the corresponding form factors turn out to be finite and gauge-invariant. Analytical expressions of the form factors are provided at leading order in the external masses. We show that flavor-changing interactions in gravity are local if the graviton is strictly massless while if the graviton has a small mass long-range interactions inducing a flavor-changing contribution in the Newton potential appear. Flavor-changing processes with massive spin-2 particles are also briefly discussed. These results can be generalized to the case of the lepton-graviton coupling.
