description: This paper presents a new progressive compression method for triangular meshes. This method, in fact, is based on a schema of irregular multi-resolution analysis and is centered on the optimization of the rate-distortion trade-off. The quantization precision is adapted to each vertex during the encoding / decoding process to optimize the rate-distortion compromise. The Optimization of the treated mesh geometry improves the approximation quality and the compression ratio at each level of resolution. The experimental results show that the proposed algorithm gives competitive results compared to the previous works dealing with the rate-distortion compromise.

description: The Lanczos algorithm has proven itself to be a valuable matrix eigensolver for problems with large dimensions, up to hundreds of millions or even tens of billions. The computational cost of using any Lanczos algorithm is dominated by the number of sparse matrix-vector multiplications until suitable convergence is reached. Block Lanczos replaces sparse matrix-vector multiplication with sparse matrix-matrix multiplication, which is more efficient, but for a randomly chosen starting block (or pivot), more multiplications are required to reach convergence. We find that a bootstrapped pivot block, that is, an initial block constructed from approximate eigenvectors computed in a truncated space, leads to a dramatically reduced number of multiplications, significantly outperforming both standard vector Lanczos and block Lanczos with a random pivot. A key condition for speed-up is that the pivot block have a non-trivial overlap with the final converged vectors. We implement this approach in a configuration-interaction code for nuclear structure, and find a reduction in time-to-solution by a factor of two or more, up to a factor of ten.

description: This study examines the effectiveness of interpretation on visitors’ knowledge, attitudes, and behavioural intentions towards environmentalconservation at the Charmouth coastal area, in the U.K. In addition, the study explores how the interpretive experience influences pro-environmental behavioural intentions along with other various variables. A pre-/post-visit questionnaire survey was conducted on-site. Results indicate that interpretation is successful in enhancing visitors’ knowledge of the environmental issues and promoting their behavioural intention. The interpretive experiences of visitors facilitate only the specific attitude related to fossil collecting activities, but no overall attitude change. In terms of the effects of various factors on behavioural intention, attitudes are more influential than knowledge. The visitors’ background and experiences are also moderatelyrelated to behavioural intention.Therefore,this studysuggeststhat interpreter’s need to approach in a more holistic and integrated basis to develop effective interpretation practice in order to promote responsible environmental behaviour.

description: We present a new method for coherent control of trapped ion qubits in separate interaction regions of a multi-zone trap by simultaneously applying an electric field and a spin-dependent gradient. Both the phase and amplitude of the effective single-qubit rotation depend on the electric field, which can be localised to each zone. We demonstrate this interaction on a single ion using both laser-based and magnetic field gradients in a surface-electrode ion trap, and measure the localisation of the electric field.

description: We report the magnetic phase transitions of a spin-5/2, 2-dimensional triangular lattice antiferromagnet (AFM) Na$_2$BaMn(PO$_4$)$_2$. From specific heat measurements, we observe two magnetic transitions at temperatures 1.15 K and 1.30 K at zero magnetic field. Detailed AC magnetic susceptibility measurements reveal multiple phases including the $\uparrow$$\uparrow$$\downarrow$ (up-up-down)-phase between 1.9 T and 2.9 T at 47 mK when magnetic field is applied along the $c$ axis, implying that Na$_2$BaMn(PO$_4$)$_2$ is a classical 2$d$ TL Heisenberg AFM with easy-axis anisotropy. However, it deviates from an ideal model as evidenced by a hump region with hysteresis between the $\uparrow$$\uparrow$$\downarrow$ and $V$-phases and weak phase transitions. Our work provides another experimental example to study frustrated magnetism in 2$d$ TL AFM which also serves as a reference to understand the possible quantum spin liquid behavior and anomalous phase diagrams observed in sibling systems Na$_2$Ba$M$(PO$_4$)$_2$ ($M$ = Co, Ni).

description: A detailed analysis of the bremsstrahlung spectrum at nonrelativistic electron scattering on argon and xenon is carried out. It is shown that the approximate formulas widely used for the description of bremsstrahlung spectra lead to predictions that significantly differ from the exact results. In the limit when the photon frequency tends to zero, a rigorous proof of the relationship between the spectrum of the bremsstrahlung with a transport cross section of electron scattering on an atom is given. This proof does not require any assumptions about the dependence of the scattering phases on energy. For electron energies lower than the luminescence threshold, it is shown that the predictions for a number of radiated photons obtained by the exact formula are in good agreement with the available experimental data.

description: We study theoretically helical edge states of 2D and 3D topological insulators (TI) tunnel-coupled to metal leads and show that their transport properties are strongly affected by contacts as the latter play a role of a heat bath and induce damping and relaxation of electrons in the helical states of TI. A simple structure that produces a pure spin current in the external circuit is proposed. The current and spin current delivered to the external circuit depend on relation between characteristic lengths: damping length due to tunneling, contact length and, in case of 3D TI, mean free path and spin relaxation length caused by momentum scattering. If the damping length due to tunneling is the smallest one, then the electric and spin currents are proportional to the conductance quantum in 2D TI, and to the conductance quantum multiplied by the ratio of the contact width to the Fermi wavelength in 3D TI.

Turismo étnico, cidades e identidades: o projecto “Sabura - África, aqui tão perto!”. Uma viragem cognitiva na apreciação da diferença
Creators: name: Costa, Francisco Lima
Publisher: name: Revista Turismo & Desenvolvimento
Year: 2006

description: As cidades sempre foram espaços de relações inter-étnicas onde pessoas de diferentes origens e passados se encontram. Os processos de globalização são sempre acompanhados pelo aumento dos fluxos migratórios, contribuindo para um aumento da diversidade cultural nas grandes cidades; neste processo, tanto o turismo como a imigração assumem um importante papel. No decurso deste trabalho salientaremos, em primeiro lugar, a relação entre turismo étnico e globalização, e seus impactos nas cidades. Num segundo momento, focalizaremos na origem e natureza do conceito de “turismo étnico” e nos caminhos problemáticos que têm vindo a ser explorados. Finalmente, procederemos, para o caso concreto de Lisboa, a uma análise das relações entre fluxos migratórios, turismo e relações inter-étnicas, discutindo os processos e quadros de produção da diferença e das dinâmicas identitárias, e a forma como umas – no caso do turismo étnico – geram ethnopaisagens (Appadurai, 1996 e Anderson, 2001) e outras – como no caso da focalização na imigração – geram fenómenos de exclusão e, até mesmo, de guetização. Apresentaremos, para o efeito, como estudo de caso: “O Projecto Sabura- África, aqui tão perto!”, no arredores de Lisboa. Mais concretamente, reflectiremos sobre a emergência deste mercado turístico e seus impactos aos níveis cultural, económico, político e social.

Expressing the entropy of lattice systems as sums of conditional entropies

Year: 2014
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: Whether a system is to be considered complex or not depends on how one searches for correlations. We propose a general scheme for calculation of entropies in lattice systems that has high flexibility in how correlations are successively taken into account. Compared to the traditional approach for estimating the entropy density, in which successive approximations builds on step-wise extensions of blocks of symbols, we show that one can take larger steps when collecting the statistics necessary to calculate the entropy density of the system. In one dimension this means that, instead of a single sweep over the system in which states are read sequentially, one take several sweeps with larger steps so that eventually the whole lattice is covered. This means that the information in correlations is captured in a different way, and in some situations this will lead to a considerably much faster convergence of the entropy density estimate as a function of the size of the configurations used in the estimate. The formalism is exemplified with both an example of a free energy minimisation scheme for the two-dimensional Ising model, and an example of increasingly complex spatial correlations generated by the time evolution of elementary cellular automaton rule 60.

description: We theoretically study the characteristics of photoelectron emission in plasmonic nanoparticle arrays. Nanoparticles are partially embedded in a semiconductor, forming Schottky barriers at metal/semiconductor interfaces through which photoelectrons can tunnel from the nanoparticle into the semiconductor; photodetection in the infrared range, where photon energies are below the semiconductor band gap (insufficient for band-to-band absorption in semiconductor), is therefore possible. The nanoparticles are arranged in a sparse rectangular lattice so that the wavelength of the lattice-induced Rayleigh anomalies can overlap the wavelength of the localized surface plasmon resonance of the individual particles, bringing about collective effects from the nanoparticle array. Using full-wave numerical simulations, we analyze the effects of lattice constant, embedding depth, and refractive index step between the semiconductor layer and an adjacent transparent conductive oxide layer. We show that the presence of refractive index mismatch between media surrounding the nanoparticles disrupts the formation of a narrow absorption peak associated with the Rayleigh anomaly, so the role of collective lattice effects in the formation of plasmonic resonance is diminished. We also show that 5 to 20-times increase of photoemission can be achieved on embedding of nanoparticles without taking into account dynamics of ballistic electrons. The results obtained can be used to increase efficiency of plasmon-based photodetectors and photovoltaic devices. The results may provide clues to designing an experiment where the contributions of surface and volume photoelectric effects to the overall photocurrent would be defined.

description: The detection of genomic regions unusually rich in a given pattern is an important undertaking in the analysis of next generation sequencing data. Recent studies of chromosomal translocations in activated B lymphocytes have identified regions that are frequently translocated to c-myc oncogene. A quantitative method for the identification of translocation hotspots was crucial to this study. Here we improve this analysis by using a simple probabilistic model and the framework provided by scan statistics to define the number and location of translocation breakpoint hotspots. A key feature of our method is that it provides a global chromosome-wide significance level to clustering, as opposed to previous methods based on local criteria. Whilst being motivated by a specific application, the detection of unusual clusters is a widespread problem in bioinformatics. We expect our method to be useful in the analysis of data from other experimental approaches such as of ChIP-seq and 4C-seq.

description: We present an algorithm and implementation of integral-direct, density-fitted Hartree-Fock (HF) and second-order Møller-Plesset perturbation theory (MP2) for periodic systems. The new code eliminates the formerly prohibitive storage requirements and allows us to study systems one order of magnitude larger than before at the periodic MP2 level. We demonstrate the significance of the development by studying the benzene crystal in both the thermodynamic limit and the complete basis set limit, for which we predict an MP2 cohesive energy of $-72.8$ kJ/mol, which is about $10$--$15$ kJ/mol larger in magnitude than all previously reported MP2 calculations. Compared to the best theoretical estimate from literature, several modified MP2 models approach chemical accuracy in the predicted cohesive energy of the benzene crystal and hence may be promising cost-effective choices for future applications on molecular crystals.

description: The recent observation of correlated phases in transition metal dichalcogenide moiré systems at integer and fractional filling promises new insight into metal-insulator transitions and the unusual states of matter that can emerge near such transitions. Here, we combine real- and momentum-space mapping techniques to study moiré superlattice effects in 57.4$^{\circ}$ twisted WSe$_2$ (tWSe$_2$). Our data reveal a split-off flat band that derives from the monolayer $Γ$ states. Using advanced data analysis, we directly quantify the moiré potential from our data. We further demonstrate that the global valence band maximum in tWSe$_2$ is close in energy to this flat band but derives from the monolayer K-states which show weaker superlattice effects. These results constrain theoretical models and open the perspective that $Γ$-valley flat bands might be involved in the correlated physics of twisted WSe$_2$.

description: Almancil é a freguesia do país com uma maior concentração de campos de golfe, representando 55% dos campos do concelho de Loulé, 22% das unidades da região e mais de 25% das voltas efectuadas pelos golfistas que procuraram o Algarve, em 2003. O golfe surge, assim, como uma das bases de sustentação do negócio turístico, neste espaço. A forma como os golfistas percebem a qualidade do campo constitui uma incógnita para a maior parte dos empresários. Neste artigo, avalia-se a forma como os golfistas posicionam cada um dos campos, a partir dos atributos que constituem a oferta. Prova-se que o golfista utiliza um número reduzido de atributos para posicionar os campos de golfe. Conclui-se que Almancil se posiciona, de forma consistente, no imaginário dos golfistas com claras vantagens competitivas relativamente às áreas de destino suas concorrentes. As vantagens competitivas de Almancil assentam na qualidade dos campos e na sua manutenção, para aqueles que, normalmente, jogam neste destino.

Two Loop Ghost free Quantisation of Wilson Loops in $\mathcal{N}=4$ supersymmetric Yang-Mills

description: We report a perturbative calculation of the expectation value of the infinite straight line Maldacena-Wilson loop in $\mathcal{N}=4$ supersymmetric Yang-Mills theory to order $g^6$. Thus, we extend the previous perturbative result by one order. The vacuum expectation value is reformulated in terms of a non-linear and non-local transformation, the Nicolai map, mapping the full functional measure of the interacting theory to that of a free bosonic theory. The results are twofold. The perturbative cancellations of the different contributions to the Maldacena-Wilson loop are by no means trivial and seem to resemble those of the circular Maldacena-Wilson loop at order $g^4$. Furthermore, we argue that our approach to computing quantum correlation functions is competitive with more standard diagrammatic techniques.

description: Due to their extremely dust-obscured nature, much uncertainty still exists surrounding the stellar mass growth and content in dusty, star-forming galaxies (DSFGs) at $z>1$. In this work, we present a numerical model built using empirical data on DSFGs to estimate their stellar mass contributions across the first $\sim$10 Gyr of cosmic time. We generate a dust-obscured stellar mass function that extends beyond the mass limit of star-forming stellar mass functions in the literature, and predict that massive DSFGs constitute as much as $50-100\%$ of all star-forming galaxies with M $\ge10^{11}$M$_\odot$ at $z>1$. We predict the number density of massive DSFGs and find general agreement with observations, although more data is needed to narrow wide observational uncertainties. We forward model mock massive DSFGs to their quiescent descendants and find remarkable agreement with observations from the literature demonstrating that, to first order, massive DSFGs are a sufficient ancestral population to describe the prevalence of massive quiescent galaxies at $z>1$. We predict that massive DSFGs and their descendants contribute as much as $25-60\%$ to the cosmic stellar mass density during the peak of cosmic star formation, and predict an intense epoch of population growth during the $\sim1$ Gyr from $z=6$ to 3 during which the majority of the most massive galaxies at high-$z$ grow and then quench. Future studies seeking to understand massive galaxy growth and evolution in the early Universe should strategize synergies with data from the latest observatories (e.g. JWST and ALMA) to better include the heavily dust-obscured galaxy population.

description: No âmbito do turismo, a imagem dos destinos tem uma importante influência no comportamento dos consumidores. No entanto, diversos estudos apontam para o facto da imagem que as pessoas possuem dos destinos turísticos poder ser influenciada pelas suas características sócio-demográficas. Este estudo tem como objectivo identificar a imagem que os visitantes do concelho de Aveiro possuem sobre este concelho e verificar se esta imagem está relacionada com as características sócio-demográficas dos visitantes. Os resultados revelam que as pessoas que visitam o concelho têm uma imagem positiva de Aveiro, particularmente em termos de atracções naturais, gastronomia e hospitalidade dos residentes. No entanto, verifica-se que a imagem é influenciada pelas características sócio-demográficas dos visitantes, nomeadamente pela sua idade, género, nível de habilitações literárias e nacionalidade.

description: When a compact object is formed in a binary, any mass lost during core collapse will impart a kick on the binary's center of mass. Asymmetries in this mass loss or neutrino emission would impart an additional natal kick on the remnant black hole or neutron star, whether it was formed in a binary or in isolation. While it is well established that neutron stars receive natal kicks upon formation, it is unclear whether black holes do as well. Here, we consider the low-mass X-ray binary MAXI J1305-704, which has been reported to have a space velocity $\gtrsim$ 200 km/s. In addition to integrating its trajectory to infer its velocity upon formation of its black hole, we account for recent estimates of its period, black hole mass, mass ratio, and donor effective temperature from photometric and spectroscopic observations. We find that if MAXI J1305-704 formed via isolated binary evolution in the thick Galactic disk, then the supernova that formed its black hole imparted a natal kick of at least 70 km/s while ejecting less than $\simeq 1$ M$_\odot$ with 95% confidence assuming uninformative priors on mass loss and natal kick velocity.

description: Tratando-se o turismo de um sector de actividade capaz de se constituir como alavanca do crescimento económico, assim como da prosperidade social e da sustentabilidade ambiental, a qualidade deve assumir um claro protagonismo, muito especialmente a nível dos destinos. Com efeito, não só é a esse nível que os turistas fazem as suas escolhas de férias, como também a avaliação que realizam a respeito desta ou daquela organização turística vem a repercutir-se na imagem global do destino. Porque a experiência turística é indissociável da totalidade de uma cadeia de valor, a qualidade deve ser encarada como uma preocupação de todos os stakeholders, e não exclusivamente da indústria turística. Abordagens no âmbito das organizações têm vindo a fundamentar a convicção de que a gestão da qualidade emana dos valores, princípios e normas prevalecentes na organização, por conseguinte, da sua cultura. Trata-se de uma perspectiva diferente, e mais alargada, a respeito da qualidade, pois transcende uma concepção estritamente instrumental. À semelhança das organizações consideradas isoladamente, também os destinos se vêem implicados numa tomada de posição proactiva a respeito da qualidade. O conceito de “cultura da qualidade”, constitutivo do paradigma cultural, é uma via possível para esse efeito. Apurar “onde se está”, “onde se quer estar” e “como lá chegar” em matéria de qualidade no destino é um exercício de análise e reflexão a realizar em paralelo com a exigência de dar condições de expressão e continuidade a uma cultura que se ambiciona integradora de todos os actores sociais. O artigo sugere possibilidades metodológicas que auxiliem na construção do conhecimento do destino turístico em matéria de cultura da qualidade e considera estratégias cuja aplicação favoreça o seu surgimento, postulando a sua existência integrada e continuada como condição do desenvolvimento sustentável da actividade turística.

description: Magneto conductivities in Weyl semimetals (WSM) in presence of small fields are studied using quasi-classical Boltzmann transport equations (BTE). Following such formalism here we consider irradiation via circularly polarized light on a two-node time reversal breaking WSM already under a dc/static electric field and study the magneto-transport properties due to the presence of chiral anomaly. Chiral anomaly affects both longitudinal magnetoconductivity as well as planar Hall conductivity. {As our field set-up causes continuous time variation in the relative orientation between the fields, one naturally expects interesting magneto-transport behavior for different field strengths and tilting.} The type-I tilting that we study here displays both positive and negative magnetoconductances depending on the field strengths and time. Furthermore, we find that a direct temporal tuning of the irradiated field strengths can {lead to fluctuating} magneto-transport behavior which can be easily improvised and checked in the laboratories.

description: In the current work, we find that a free axisymmetric jet in air displays self-similarity in the fully developed part of the jet. We report accurate measurements of first, second and third order, spatially averaged statistical functions of the axial velocity component performed with a laser Doppler anemometer, including in the outer (high intensity) regions of the jet. The measurements are compared to predictions derived from a simple jet model, described in a separate publication, and we discuss the implications for the further study of self-similarity in a free jet. It appears that all statistical functions included in this study can be scaled with a single geometrical scaling factor -- the downstream distance from a common virtual origin.

description: Systems of spins engineered with tunable density and reduced dimensionality enable a number of advancements in quantum sensing and simulation. Defects in diamond, such as nitrogen-vacancy (NV) centers and substitutional nitrogen (P1 centers), are particularly promising solid-state platforms to explore. However, the ability to controllably create coherent, two-dimensional spin systems and characterize their properties, such as density, depth confinement, and coherence is an outstanding materials challenge. We present a refined approach to engineer dense ($\gtrsim$1 ppm$\cdot$nm), 2D nitrogen and NV layers in diamond using delta-doping during plasma-enhanced chemical vapor deposition (PECVD) epitaxial growth. We employ both traditional materials techniques, e.g. secondary ion mass spectrometry (SIMS), alongside NV spin decoherence-based measurements to characterize the density and dimensionality of the P1 and NV layers. We find P1 densities of 5-10 ppm$\cdot$nm, NV densities between 1 and 3.5 ppm$\cdot$nm tuned via electron irradiation dosage, and depth confinement of the spin layer down to 1.6 nm. We also observe high (up to 0.74) ratios of P1 to NV centers and reproducibly long NV coherence times, dominated by dipolar interactions with the engineered P1 and NV spin baths.

description: O artigo remete para um quadro de avaliação, corrente e unânime, sobre as virtualidades da coexistência e articulação dos dois fenómenos: cultura (aqui representado pelo património arquitectónico) e turismo. Para o estudo destas questões foram analisadas propostas de oferta organizadas por um conjunto de operadores turísticos que programam o Norte de Portugal e que referem, ou integram, nos seus percursos os concelhos de Amarante e Vila Real. As conclusões dão lugar a uma análise da procura, donde resulta a caracterização das suas opiniões face a questões relacionadas com a utilização do património arquitectónico.

A acessibilidade da oferta turística para pessoas portadoras de deficiências: o caso do município da Lousã como exemplo de boas práticas
Creators: name: Devile, Eugénia Lima
Publisher: name: Revista Turismo & Desenvolvimento
Year: 2006

description: O conceito de Turismo Acessível ou de Turismo para Todos prevê o acesso às instalações e serviços turísticos e à oferta de serviços e atividades orientada aos gostos e preferências de pessoas portadoras de deficiência ou com necessidades e exigências diferentes dos outros segmentos da procura. Ou seja, qualquer cidadão com mobilidade reduzida deve poder aceder ao que está à disposição de qualquer outro turista, em segurança, sem ter que recorrer a serviços específicos. Grande parte dos obstáculos que se colocam às pessoas portadoras de deficiência nas suas atividades turísticas resulta da falta de conhecimento das suas necessidades específicas e também da desvalorização do seu potencial, enquanto segmento de procura turística. Neste artigo, pretende-se analisar os principais aspetos da acessibilidade dos serviços turísticos para pessoas com mobilidade reduzida e o papel dos diferentes atores na remoção das barreiras existentes, utilizando como caso de estudo o município da Lousã.

description: Os quadros comunitários são um forte incentivo ao desenvolvimento territorial e estão assentes em fatores de inovação e modernização, de qualificação dos recursos humanos e de valorização do território. Estão assentes na preocupação das questões ambientais e de sustentabilidade, nos fatores imateriais de competitividade das empresas e dos territórios. Neste caso específico pretendemos dar o nosso contributo sobre o QREN, que poderá ser uma oportunidade para aprofundar as experiências do anterior Quadro Comunitário de Apoio. O objetivo é contribuir para consolidar o caminho do desenvolvimento sustentado do turismo, no âmbito do futuro QREN, através de três linhas de ação que entendemos como fundamentais: A criação de um label associado a boas práticas de turismo sustentável, e aplicável a diferentes tipologias de projetos e iniciativas; A informação/formação através da disponibilização de mais informação e promoção de formação junto dos potenciais promotores; e finalmente a articulação entre fontes de financiamento sectorial e institucional, de forma a congregar para os mesmos objetivos estratégicos prioritários de desenvolvimento territorial as diferentes fontes e sistemas de financiamento que vierem a ser definidos.

description: We propose a simple system of optically driven colloids that convert light into heat and move in response to self- and collectively- generated thermal gradients. We show that the system exhibits self-organization into a moving comet-like swarm and characterize the structure and response of the swarm to a light intensity dependent external tuning parameter. We observe many interesting features in this nonequilibrium system including circulation and evaporation, intensity-dependent shape, density and temperature fluctuations, and ejection of hot colloids from the swarm tip.
