description: Learning is a process which involves both teaching and learning. The integration of education with technology implies a strategy named blended learning. Flipped learning is one such approach which is a type of blended learning where lectures are provided to the learners as video lessons previously before the class hours. Thus, it pays a way for additional learning time using activities inside the class. Flipped learning is effective only when the principles of flipped learning (also known as “Pillars of Flipped Learning”) are followed in a systematic way. In this technological era, an active learning and teaching happens when such integrated strategy is used. This research paper theoretically explains blended learning, flipped learning and its pillars. It also analyses the way in which flipped learning is used to promote active teaching and learning.

description: A clear correlation exists between microbiota and the dysregulation of the immune response in Inflammatory Bowel Diseases (IBD), which comprise Crohn’s disease (CD) and ulcerative colitis (UC). These unbalanced reactions also involve humoral responses, with antibodies against Saccharomyces cerevisiae. Thus, here we aimed to quantify IgA and IgG specific to S. cerevisiae (ASCA) in quiescent CD and UC, to correlate the production of these antibodies with patient’s inflammatory response and disease clinical presentation. Twenty-nine subjects (16 CD and 13 UC) and 45 healthy controls were enrolled in this study and had plasma samples tested for ASCA and cytokines (IL-2, IL-4, IL-6, IL-10, IFN-γ, TNF-α), besides clinical evaluation. IBD patients had increase IgA and IgG ASCA, especially those with colonic (L2) and fistulizing (B3) CD. Similarly, patients who dropped out the treatment had augmented ASCA, while IgG was reduced in those receiving sulfasalazine treatment. Furthermore, the quiescent CD patients had elevated IL-6 on plasma, especially in the absence of treatment, together with increased counter regulatory response of IL-10. There was a positive correlation between IgA and IgG on CD but not UC, as well as between IgA and TNF in total IBD patients. In addition, the levels of IgG x TNF, IgA x IL-10 and IgG x IL-10 were also correlated in CD, indicating that ASCA production may be influenced by the inflammatory response. Finally, we concluded that ASCA could be pointed as relevant biomarker of CD presentation and residual inflammation, even in clinical remission patients.

description: A novel approach to heteropolymer design is proposed. It is based on the criterion by Kurosky and Deutsch, with which the probability of a target conformation in a conformation space is maximized at low but finite temperature. The key feature of the proposed approach is the use of soft spins (fuzzy monomers) that leads to a design equation, which is an analog of the Boltzmann machine learning equation in the design problem. We implement an algorithm based on the design equation for the generalized HP model on the 3x3x3 cubic lattice and check its performance.

description: This paper introduces an augmented reality application for web that works without markers. We propose a solution to manipulate virtual objects without using markers, i.e. we replaced the physical marker by user face. For this we had to develop also a method to manipulate the virtual models (e.g. to rotate models) based on user gesture allowing doing the same as the marker. Finally we present a simple augmented web game showing our approach without the use of markers.

Induced instability for boson-fermion mixed condensate of Alkali atoms due to attractive boson-fermion interaction

description: Instabilities for boson-fermion mixed condensates of trapped Alkali atoms due to the boson-fermion attractive interaction are studied using a variational method. Three regions are shown for their instabilities according to the boson-fermion interaction strength: stable, meta-stable and unstable ones. The stability condition is obtained analytically from the asymptotic expansion of the variational total energy. The life-time of metastable states is discussed for tunneling decay, and is estimated to be very long. It suggests that, except near the unstable border, meta-stable mixed condensate should be almost-stable against clusterizations. The critical border between meta-stable and unstable phases is calculated numerically and is shown to be consistent with the Mølmer scaling condition.

description: The present article aims to describe the efforts taken in order to create a generic computing solution for the most recurrent problems, usually found in the production of two dimensional, sprite-based videogames, running on mobile platforms. The developed system is a web application that fits within the scope of the recent cloudcomputing paradigm and, therefore, enjoys all of its advantages in terms of accessibility, application maintainability and scalability. In addition to the functional issues, the system is also explained in terms of its software architecture, since it was planned and implemented in the perspective of attaining an easy to maintain application that is both scalable and adaptable. Additionally, an algorithm is also proposed, seeking to find an optimized solution to the problem of space distribution for several rectangular areas, with no overlapping and no dimensional restrictions, neither on the final arrangement nor on the arranged areas.

description: Four new heteroleptic copper(I) complexes bearing either 2-pyridyl-1,2,3-triazole (pytri) or the related triphenylamine (TPA) substituted (TPA-tripy) ligands and the ancillary ligands 6,6′-dimesityl-2,2′-bipyridine (diMesbpy) or bis[(2-diphenylphosphino)phenyl] ether (POP) were synthesized in good yields (75-95%). All the complexes were extensively characterized using nuclear magnetic resonance (NMR) spectroscopies and electrospray ionization mass spectrometry (ESIMS) and in the case of the two pytri compounds the solid state structures were determined via X-ray crystallography. The pytri complexes showed MLCT absorption bands which shift from 433 nm for the diMesbpy complex to 347 nm for POP. TPA-pytri complexes introduce an ILCT band resulting in improved visible absorption (376 nm, 26,400 M−1 cm−1 for [Cu(TPA-pytri)(diMesbpy)](PF6)). Emission from this ILCT state (470 nm, Φ = 0.08) was red-shifted compared to the free ligand with negligible effects from ancillary ligands. Band assignments were confirmed with resonance Raman spectroscopy and TD-DFT calculations.

description: In this work we have considered a minimal extension of Standard Model by a local $U(1)$ gauge group in order to accommodate a stable (fermionic) Dark Matter (DM) candidate. We have focussed on parameter regions where DM possesses adequate self interaction, owing to the presence of a light scalar mediator (the dark Higgs), alleviating some of the tensions in the small-scale structures. We have studied the scenario in the light of a variety of data, mostly from dark matter direct searches, collider searches and flavour physics experiments, with an attempt to constrain the interactions of the standard model (SM) particles with the ones in the Dark Sector (DS). Assuming a small gauge kinetic mixing parameter, we find that for rather heavy DM %$\gtrsim \mathcal{O}(1-10)\,\, {\rm GeV}$%, the most stringent bound on the mixing angle of the Dark Higgs with the SM Higgs boson comes from dark matter direct detection experiments, while for lighter DM, LHC constraints become more relevant. Note that, due to the presence of very light mediators the usual realisation of direct detection constraints in terms of momentum independent cross sections had to be reevaluated for our scenario. In addition, we find that the smallness of the relevant portal couplings, as dictated by data, critically suppress the viability of DM production by the standard "freeze-out" mechanism in such simplified scenarios. In particular, the viable DM masses are $\lesssim \mathcal{O}(2)$ GeV $i.e.$ in the regions where direct detection limits tend to become weak. For heavier DM with large self-interactions, we hence conclude that non-thermal production mechanisms are favoured. Lastly, future collider reach of such a simplified scenario has also been studied in detail.

description: Neste artigo descrevemos a construção de uma interface adaptativa para o Caderno Escolar Electrónico, capaz de prever qual a tarefa mais provável que o utilizador irá efectuar no sistema, com base num conhecimento prévio das acções já efectuadas, assim como no tempo e percurso efectuado até determinada altura. Esta adaptabilidade visa a melhoria da interacção entre o sistema e o seu utilizador, reduzindo assim o número de interacções explícitas necessárias para efectuar uma determinada tarefa. Para conseguir prever as tarefas mais prováveis em determinada situação, o sistema recorre a algoritmos de classificação, baseados em árvores de decisão e redes de Markov. Os utilizadores com necessidades especiais, são o principal alvo deste projecto, mas o sistema poderá também dar um grande contributo a outros utilizadores em idade escolar, dado que esta ferramenta favorece a adopção de um processo metódico para recolha e organização de notas em contexto de sala de aula. Por ter sido desenvolvido com recurso a técnicas de desenho para sistemas interactivos, encontra-se totalmente adaptado aos utilizadores alvos.

description: This paper develops an extension of Krugman’s Core–Periphery (CP) model by considering a competitive primary sector that extracts a renewable natural resource. The dynamics of the resource give rise to a new dispersion force: the resource effect. If primary goods are not tradable, lower trade costs boost dispersion, and the agglomeration–dispersion transition is sudden or smooth depending on the productivity of the primary sector. Cyclic behaviours arise for high levels of productivity in resource extraction. If primary goods are tradable, in most cases, the symmetric equilibrium goes from stable to unstable as the openness of trade increases.

description: We consider an optimization problem posed by an actual newspaper company, which consists of computing a minimum length route for a delivery truck, such that the driver only stops at street crossings, each time delivering copies to all customers adjacent to the crossing. This can be modeled as an abstract problem that takes an unweighted simple graph $G = (V, E)$ and a subset of edges $X$ and asks for a shortest cycle, not necessarily simple, such that every edge of $X$ has an endpoint in the cycle. We show that the decision version of the problem is strongly NP-complete, even if $G$ is a grid graph. Regarding approximate solutions, we show that the general case of the problem is APX-hard, and thus no PTAS is possible unless P $=$ NP. Despite the hardness of approximation, we show that given any $α$-approximation algorithm for metric TSP, we can build a $3α$-approximation algorithm for our optimization problem, yielding a concrete $9/2$-approximation algorithm. The grid case is of particular importance, because it models a city map or some part of it. A usual scenario is having some neighborhood full of customers, which translates as an instance of the abstract problem where almost every edge of $G$ is in $X$. We model this property as $|E - X| = o(|E|)$, and for these instances we give a $(3/2 + \varepsilon)$-approximation algorithm, for any $\varepsilon > 0$, provided that the grid is sufficiently big.

description: A importância da familiarização das crianças com a tecnologia é cada vez mais notável: quer porque esta faz parte inquestionável do mundo que a rodeia, quer pela relevância educativa das experiências que lhe pode proporcionar. As crianças do pré-escolar são um grupo de utilizadores especiais, uma vez que se encontram numa fase inicial das suas vidas, onde têm de aprender a viver em sociedade, isto é, aprender a ouvir e respeitar as opiniões dos outros, partilhar os mesmos objectos e também a ajudar-se mutuamente. Neste estudo, foi desenhado e desenvolvido um jogo em Realidade Aumentada para o ensino de conceitos simples que promove acções colaborativas entre as crianças. Todo o design do jogo foi devidamente acompanhado por educadoras. Os resultados sugerem que o jogo é eficaz para obter níveis altos de concentração, envolvimento, motivação e curiosidade que levam a que haja uma maior colaboração entre as crianças, particularmente quando o feedback (resultado) do jogo é fornecido de forma imediata. Embora já existam diversas soluções voltadas para o ensino, tais como jogos sobre a matemática, geometria e sobre o sistema solar, existe claramente uma falta de soluções e estudos sobre a aplicação desta tecnologia com crianças do pré-escolar (3 aos 5/6 anos). Esta foi uma das principais razões que nos levou a desenvolver esta investigação.

Os resultados mostraram que para cada técnica a eficácia e precisão varia de acordo com as diferentes parametrizações. Regra geral, o Tapping (método tradicional) foi a técnica de interacção preferida e entre as mais eficazes. Isto mostra que é possível criar interfaces unificadas e acessíveis a utilizadores com e sem deficiências, caso existam métodos de parametrização ou adaptação apropriados.

description: A qualidade dos jardins de lar é um ponto fundamental para a qualidade de vida do idoso. A persecução deste objectivo nem sempre é simples para o projectista, porque existem muitas lacunas na literatura sobre a relação entre as características de um jardim e as motivações, capacidades e limitações do sénior. Neste contexto, este trabalho corresponde a uma fase preliminar de um projecto de investigação mais lato e tem como objectivo a apresentação de uma metodologia para o desenvolvimento de um guião de entrevista (tratandose de um pré-teste), para se conhecer a forma como os idosos interagem com um jardim de lar, em função das características de jardins existentes. Foram fotografados quatro jardins de lares portugueses e seleccionadas vinte e três fotografias em função dos seguintes critérios: elementos do design e de composição dum jardim, aliados às actividades de lazer. Tendo como ponto de partida estes elementos, desenvolvemos um primeiro guião de uma entrevista com doze perguntas que foram testadas com cinco idosos entrevistados (Estudo Piloto). Durante a entrevista verificámos a necessidade de rever quatro fotografias, em que manifestaram dificuldades em identificar os elementos gráficos; no entanto, para a generalidade dos aspectos, não identificámos problemas de compreensão. Os resultados desta entrevista mostraram que a metodologia utilizada foi eficaz para medir a forma como os idosos manifestam as suas intenções comportamentais no que se refere à sua interacção com os jardins de lar. Após a modificação deste guião, ele será aplicado a uma amostra significativa de idosos, com o objectivo de recolher conhecimento útil na elaboração de cenários para jardins de lar.

description: A quantum pumping mechanism which produces dc current or voltage in response to a cyclic deformation of the confining potential in an open quantum dot is reported. The voltage produced at zero current bias is sinusoidal in the phase difference between the two ac voltages deforming the potential and shows random fluctuations in amplitude and direction with small changes in external parameters such as magnetic field. The amplitude of the pumping response increases linearly with the frequency of the deformation. Dependencies of pumping on the strength of the deformations, temperature, and breaking of time-reversal symmetry are also investigated.

We consider the 2D system located at the interface between two dielectric media with different dielectric constants. An external dc magnetic field is assumed to be directed along the normal to the 2D electron layer. In such a configuration the cyclotron-polaritons (CPs) in 2D electron system can be excited with the frequencies in the vicinity of the cyclotron frequency. Under the CPs excitation the resonance polarisation conversion of electromagnetic wave greatly increases in the system. In the absence of the electron scattering in 2D system, the polarisation conversion reaches 100% at a certain value of the angle of incidence which is more than the total reflection angle. Extremely high polarisation conversion takes place in a quite wide range of variation of the angle of incidence. High polarisation conversion efficiency (above 80%) remains when the actual electron scattering in the 2D system on GsAs is taken into account. The considered phenomena may be taken up in polarisation spectroscopy of 2D electron systems.

On the metal-insulator transition in the two-chain model of correlated fermions

description: The doping-induced metal-insulator transition in two-chain systems of correlated fermions is studied using a solvable limit of the t-J model and the fact that various strong- and weak-coupling limits of the two-chain model are in the same phase, i.e. have the same low-energy properties. It is shown that the Luttinger-liquid parameter K_ρtakes the universal value unity as the insulating state (half-filling) is approached, implying dominant d-type superconducting fluctuations, independently of the interaction strength. The crossover to insulating behavior of correlations as the transition is approached is discussed.

description: O processo de fisioterapia consiste em devolver alguma qualidade de vida a deficientes motores, através do treino de um conjunto de movimentos. Cabe ao fisioterapeuta conseguir observar, interpretar e avaliar o estado actual e evolução dos seus pacientes, de forma a maximizar o seu desempenho físico. Neste artigo, apresentamos uma análise ao processo actual de fisioterapia, num centro de reabilitação para tetraplégicos, identificando as suas principais limitações e oportunidades para uma ferramenta tecnológica. Seguindo uma abordagem de desenho centrado no utilizador, é descrita uma plataforma de suporte aos fisioterapeutas, cujo principal objectivo é tornar a reabilitação num processo mais fiável e robusto. Avaliações preliminares com a população-alvo confirmam a utilidade da nossa abordagem, contribuindo para um acompanhamento mais preciso. Por fim, são apresentados alguns cenários de interacção ilustrando todas as potencialidades do sistema.

Universality class for bootstrap percolation with $m=3$ on the cubic lattice

description: We study the $m=3$ bootstrap percolation model on a cubic lattice, using Monte Carlo simulation and finite-size scaling techniques. In bootstrap percolation, sites on a lattice are considered occupied (present) or vacant (absent) with probability $p$ or $1-p$, respectively. Occupied sites with less than $m$ occupied first-neighbours are then rendered unoccupied; this culling process is repeated until a stable configuration is reached. We evaluate the percolation critical probability, $p_c$, and both scaling powers, $y_p$ and $y_h$, and, contrarily to previous calculations, our results indicate that the model belongs to the same universality class as usual percolation (i.e., $m=0$). The critical spanning probability, $R(p_c)$, is also numerically studied, for systems with linear sizes ranging from L=32 up to L=480: the value we found, $R(p_c)=0.270 \pm 0.005$, is the same as for usual percolation with free boundary conditions.

description: O treino de competências sociais, como parte da psicoterapia, para crianças e adolescentes, requer que estes participem em actividades exteriores, nas quais têm que completar tarefas, tais como falar com alguém ou visitar um local especifico. De momento, a incapacidade, por parte dos terapeutas, de monitorizar os seus pacientes, promover esforços colaborativos e fortalecer atitudes positivas, é uma questão importante que afecta tanto o processo da terapia como os seus resultados. Neste artigo detalhamos a avaliação de um protótipo para um sistema colaborativo móvel e georreferenciado que suporta terapia de grupo in-situ. O sistema visa fornecer meios ao terapeutas, para monitorizar os seus pacientes, as suas localizações e os seus feitos, e inclui mecanismos de comunicação que facilitam a cooperação entre pacientes e terapeuta. Descrevemos o conceito por detrás do projecto, os protótipos de baixa fidelidade e os testes que foram levados a cabo para validá-los. São discutidos resultados e o é esboçado o trabalho futuro.

Electron and Nuclear Spin Dynamics in Antiferromagnetic Molecular Rings

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We study theoretically the spin dynamics of the ferric wheel, an antiferromagnetic molecular ring. For a single nuclear or impurity spin coupled to one of the electron spins of the ring, we calculate nuclear and electronic spin correlation functions and show that nuclear magnetic resonance (NMR) and electron spin resonance (ESR) techniques can be used to detect coherent tunneling of the Neel vector in these rings. The location of the NMR/ESR resonances gives the tunnel splitting and its linewidth an upper bound on the decoherence rate of the electron spin dynamics. We illustrate the experimental feasibility of our proposal with estimates for Fe_10 molecules.

description: Four new heteroleptic copper(I) complexes bearing either 2-pyridyl-1,2,3-triazole (pytri) or the related triphenylamine (TPA) substituted (TPApytri) ligands and the ancillary ligands 6,6′-dimesityl-2,2′-bipyridine (diMesbpy) or bis[(2-diphenylphosphino)phenyl] ether (POP) were synthesized in good yields (75-95%). All the complexes were extensively characterized using nuclear magnetic resonance (NMR) spectroscopies and electrospray ionization mass spectrometry (ESIMS) and in the case of the two pytri compounds the solid state structures were determined via X-ray crystallography. The pytri complexes showed MLCT absorption bands which shift from 433 nm for the diMesbpy complex to 347 nm for POP. TPA-pytri complexes introduce an ILCT band resulting in improved visible absorption (376 nm, 26400 M−1 cm−1 for [Cu(TPA-pytri)(diMesbpy)](PF6)). Emission from this ILCT state (470 nm, Φ = 0.08) was redshifted compared to the free ligand with negligible effects from ancillary ligands. Band assignments were confirmed with resonance Raman spectroscopy and TD-DFT calculations.

description: We propose a developmental approach that allows a robot to interpret and describe the actions of human agents by reusing previous experience. The robot first learns the association between words and object affordances by manipulating the objects in its environment. It then uses this information to learn a mapping between its own actions and those performed by a human in a shared environment. It finally fuses the information from these two models to interpret and describe human actions in light of its own experience. In our experiments, we show that the model can be used flexibly to do inference on different aspects of the scene. We can predict the effects of an action on the basis of object properties. We can revise the belief that a certain action occurred, given the observed effects of the human action. In an early action recognition fashion, we can anticipate the effects when the action has only been partially observed. By estimating the probability of words given the evidence and feeding them into a pre-defined grammar, we can generate relevant descriptions of the scene. We believe that this is a step towards providing robots with the fundamental skills to engage in social collaboration with humans.

Fermi's golden rule in a mesoscopic metal ring

description: We examine the time-dependent non-equilibrium current in a mesoscopic metal ring threaded by a static magnetic flux phi that is generated by a time-dependent electric field oscillating with frequency omega. We show that in quadratic order in the field there are three fundamentally different contributions to the current. (a) A time-independent contribution which can be obtained from a thermodynamic derivative. (b) A term increasing linearly in time that can be understood in terms of Fermi's golden rule. The derivation of this term requires a careful treatment of the infinitesimal imaginary parts that are added to the real frequency omega when the electric field is adiabatically switched on. (c) Finally, there is also a time-dependent current oscillating with frequency 2 omega. We suggest an experiment to test our results.
