description: Os ambientes e aplicações móveis têm sido alvo de pesquisa extensiva, com foco nas questões de usabilidade e experiência de utilização. Métodos como gravação de video, Feiticeiro de Oz ou etnografia são amplamente usados para cobrir as referidas questões. Porém, estes métodos dependem de dados observacionais ou emoções expressas pelos utilizadores em situações pós-teste, que poderão não corresponder à verdade. A utilização de modalidades de interacção fisiológica é um tema que ganha ímpeto no qual sinais biológicos provenientes dos invidíduos são usados como meio de interacção com um sistema ou aplicação. Este tipo de interacção permite aos investigadores e programadores o acesso a dados que estariam ocultos caso utilizassem as técnicas de análise convencionais acima referidas. Este artigo descreve o uso destas técnicas de interacção em ambientes movies através do uso de um electrocardiograma portátil de forma a analisar o ritmo cardíaco dos utilizadores enquanto interagem neste contexto.

description: The automatic adjustment of mobile user interfaces to the contexts in which they are used presents a possible solution for the interaction difficulties introduced by the constantly mutating characteristics of such contexts. Here we present a prototype of a portable media player. This player automatically adjusts its volume according to the users' preferences and the noise of the surrounding environment. We focus on the details of the volume adjustment algorithm and its – laboratorial and contextual - user centered evaluations. We detail the problems found on each phase of the evaluation procedure, and present a set of Wizard of Oz experiments exploring possible solutions for those problems.

description: Este artigo descreve uma experiência de desenvolvimento de um Sistema de Informação (SI) na área da saúde, que beneficiou das práticas de Projecto Centradas no Utilizador (PCU), num ambiente de 'Participatory Design' (PD). Um conjunto de técnicas oriundas das disciplinas de Interacção Humano-Computador (IHC) e da Engenharia de Usabilidade (EU), combinadas com as tradicionais da Engenharia de Software (ES), permitiram chegar a uma solução eficaz e, do ponto de vista do utilizador, usável. Com base nesta experiência foi possível concluir, em conformidade com a literatura, os bons resultados normalmente conseguidos com a aplicação de abordagens PCU, em ambiente de PD. No entanto, e apesar destes bons resultados, a experiência com este projecto leva a acreditar que se não existir um certo controlo do procedimento por parte do analista, o processo de alteração de requisitos pode tornar- se infindável, devido ao ambiente favorável para a mudança rápida de ideias e, consequentemente, propício à reformulação dos requisitos.

description: When developing interactive applications, considering the correctness of graphical user interfaces (GUIs) code is essential. GUIs are critical components of today's software, and contemporary software tools do not provide enough support for ensuring GUIs' code quality. GUIsurfer, a GUI reverse engineering tool, enables evaluation of behavioral properties of user interfaces. It performs static analysis of GUI code, generating state machines that can help in the evaluation of interactive applications. This paper describes the design, software architecture, and the use of GUIsurfer through an example. The tool is easily re-targetable, and support is available to Java/Swing, and WxHaskell. The paper sets the ground for a generalization effort to consider rich internet applications. It explores the GWT web applications' user interface programming toolkit.

description: The Resilient Dairy Genome Project (RDGP) is an international large-scale applied research project that aims to generate genomic tools to breed more resilient dairy cows. In this context, improving feed efficiency and reducing greenhouse gases from dairy is a high priority. The inclusion of traits related to feed efficiency (e.g., dry matter intake [DMI]) or greenhouse gases (e.g., methane emissions [CH4]) relies on available genotypes as well as high quality phenotypes. Currently, 7 countries (i.e., Australia, Canada, Denmark, Germany, Spain, Switzerland, and United States) contribute with genotypes and phenotypes including DMI and CH4. However, combining data are challenging due to differences in recording protocols, measurement technology, genotyping, and animal management across sources. In this study, we provide an overview of how the RDGP partners address these issues to advance international collaboration to generate genomic tools for resilient dairy. Specifically, we describe the current state of the RDGP database, data collection protocols in each country, and the strategies used for managing the shared data. As of February 2022, the database contains 1,289,593 DMI records from 12,687 cows and 17,403 CH4 records from 3,093 cows and continues to grow as countries upload new data over the coming years. No strong genomic differentiation between the populations was identified in this study, which may be beneficial for eventual across-country genomic predictions. Moreover, our results reinforce the need to account for the heterogeneity in the DMI and CH4 phenotypes in genomic analysis.
Description of juvenile specimens of Prosaurolophus maximus (Hadrosauridae: Saurolophinae) from the Upper Cretaceous Bearpaw Formation of southern Alberta, Canada, reveals ontogenetic changes in crest morphology

description: Three juvenile specimens of Prosaurolophus maximus, represented by articulated to disarticulated skeletons, are the smallest known individuals for the taxon. Cranial anatomy of the juvenile specimens indicates that diagnostic characters of P. maximus are ontogenetically variable. In the smallest individual, the crest and deeply excavated fossa at the caudal margin of the circumnarial depression are poorly developed or absent. The crest approaches adult-like morphology in large juveniles, whereas crest robusticity and the deep excavation of the circumnarial depression occur only in subadult and adult individuals. The shape of the caudal margin of the circumnarial depression is consistent between juvenile and adult individuals, potentially making this feature a reliable character for taxonomic identification at younger ontogenetic stages. The crest of P. maximus grows isometrically during ontogeny, unlike the positive allometric growth of lambeosaurine hadrosaur crests, suggesting that this taxon may have had soft tissue structures associated with the narial-crest region, rather than the bony crest itself, selected for sexual display. Recovered from sediments of the Bearpaw Formation deposited during the Baculites compressus ammonite zone and magnetochrons 33n.3n to 33n.2n, the juvenile specimens are stratigraphically younger than P. maximus specimens from the Dinosaur Park Formation (Alberta) and contemporaneous with most specimens from the Two Medicine Formation (Montana), extending the temporal range of the taxon to 75.7–74 Ma. The occurrence of P. maximus in well-drained terrestrial deposits of the Dinosaur Park and Two Medicine formations and marine sediments of the Bearpaw Formation indicates that this taxon inhabited various paleoenvironments in western North America.
Band-theoretical prediction of magnetic anisotropy in uranium monochalcogenides

description: Magnetic anisotropy of uranium monochalcogenides, US, USe and UTe, is studied by means of fully-relativistic spin-polarized band structure calculations within the local spin-density approximation. It is found that the size of the magnetic anisotropy is fairly large (about 10 meV/unit formula), which is comparable with experiment. This strong anisotropy is discussed in view of a pseudo-gap formation, of which crucial ingredients are the exchange splitting of U 5f states and their hybridization with chalcogen p states (f-p hybridization). An anomalous trend in the anisotropy is found in the series (US>>USe

description: In the context of our research project, we propose an interactive tool (GuessXQ) to perform the access to the information in a collection of eXtensible Markup Language (XML) documents. Due to the complex nature of those structured documents, the associated standard query language is also complex and, thus, not easy for most of the users. The GUI we propose does not require any knowledge about the query language, it is based on the Query-By-Example (QBE) paradigm from traditional databases. Using QBE, instead of specifying the desired components of the documents and eventual restrictions in a query, the user exemplifies those components marking them directly on a sample document picked-up from the collection. We believe this leverages the user's cognition about the object to search. GuessXQ is then responsible for the generation of the query to be treated by the information retrieval engine.

description: Previous research has shown that the presentation of valenced information about a target stimulus sometimes has different effects on implicit and explicit stimulus evaluations. Importantly, however, research examining the moderators of implicit-explicit dissociations has often failed to account for differences in the properties of the instruments used to measure implicit and explicit evaluations, preventing a clear interpretation of the results. In an effort to overcome these limitations, we conducted a study that probed the impact of valenced information on implicit and explicit evaluations as measured with procedures that were matched on methodological factors. Participants first read positive and negative information about a person named Bob and then completed measures of implicit and explicit evaluations of Bob. We examined the moderating effect of three characteristics: information diagnosticity, primacy, and whether information retrieval was cued during evaluation. Results of two high-powered experiments showed an effect of diagnosticity on implicit and explicit evaluations, replicating previous work, and extending it to new evaluation measures. We observed primacy effects on explicit evaluations in Experiment 1 and on implicit evaluations in Experiment 2. However, we did not observe memory cueing effects or any interactions. We discuss practical implications as well as implications for cognitive evaluation theories.

description: NMR, muSR, magnetization and specific heat measurements in Li(2)VOSiO(4) powders and single crystals are reported. Specific heat and magnetization measurements evidence that Li(2)VOSiO(4) is a frustrated two-dimensional S=1/2 Heisenberg antiferromagnet on a square lattice with a superexchange coupling J_1, along the sides of the square, almost equal to J_2, the one along the diagonal ($J_2/J_1=1.1\pm 0.1$ with $J_2 + J_1 = 8.2\pm 1$ K). At $T_c\simeq 2.8$ K a phase transition to a low temperature collinear order is observed. T_c and the sublattice magnetization, derived from NMR and muSR, were found practically independent on the magnetic field intensity up to 9 Tesla. The critical exponent of the sublattice magnetization was estimated $β\simeq 0.235$, nearly coincident with the one predicted for a two-dimensional XY system on a finite size. The different magnetic properties found above and below T_c are associated with the modifications in the spin hamiltonian arising from a structural distortion occurring just above T_c.

description: The thermal properties of silver are calculated within the quasi-harmonic approximation, by using phonon dispersions from density-functional perturbation theory, and the pseudopotential plane-wave method. The resulting free energy provides predictions for the temperature dependence of various quantities such as the equilibrium lattice parameter, the bulk modulus, and the heat capacity. Our results for the thermal properties are in good agreement with available experimental data in a wide range of temperatures. As a by-product, we calculate phonon frequency and Grueneisen parameter dispersion curves which are also in good agreement with experiment.

description: Arbuscular mycorrhizal fungi (AMF) are mutualistic fungi that play important roles in plant nutrition and soil ecosystem functions. While AMF are known to benefit diverse host plants under a range of conditions, little is known about their presence in commercial almond orchards and how frequently used management practices regulate AMF root colonisation. A large-scale survey of almond orchards in the Central Valley of California was conducted to determine the extent of mycorrhizal associations with roots and the impact of orchard management practices and soil properties on AMF root colonisation rates. The roots in all orchards were colonised, with an overall average rate of 64.4%. Organically managed orchards had higher AMF root colonisation rates (73.2%) as compared with conventionally managed orchards (62.1%), primarily due to the presence of soil vegetative cover rather than organic matter inputs. Choice of rootstock and fumigation had only marginal effects while inoculation at planting increased AMF root colonisation of young trees by 27% compared to non-inoculated control. These results highlighted the ubiquitous presence of AMF in commercial almond orchards and significant interacting influences of common management practices on AMF root colonisation under field conditions. Further research into the functional implications of mycorrhizal associations in these orchards will help guide the development of management practices that increase AMF abundance and root colonisation to improve the sustainability of this rapidly expanding industry.
Amplitude of jump motion signatures in classical vibration-jump dynamic

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

description: The classical Langevin dynamics of a particle in a periodic potential energy landscape are studied via the intermediate scattering function (ISF). By construction, the particle performs coupled vibrational and activated jump motion with a wide separation of the vibrational period and the mean residence time between jumps. The long time limit of the ISF is a decaying tail proportional to the function that describes ideal jump motion in the absence of vibrations. The amplitude of the tail is unity in idealized jump dynamics models, but is reduced from unity by the intra-well motion. Analytical estimates of the amplitude of the jump motion signature are provided by assuming a \textcolor{blue}{factorization of the conditional probability density of the particle position at long times, motivated by the separation of time scales associated with inter-cell and intra-cell motion}. The assumption leads to a factorization of the ISF at long correlation times, where one factor is an ideal jump motion signature, and the other component is the amplitude of the signature. The amplitude takes the form of a single-particle anharmonic Debye-Waller factor. The factorization approximation is exact at the diffraction conditions associated with the periodic potential. Numerical simulations of the Langevin equation in one and two spatial dimensions confirm that for a strongly corrugated potential the analytical approximation provides a good qualitative description of the trend in the jump signature amplitude, between the points where the factorization is exact.

description: Tirar o maior aproveitamento possível da experiência de visita em espaços como museus ou exposições tem sido alvo de muitos estudos. Neste projecto foram exploradas as potencialidades de comunicação de plataformas de personagens virtuais como tecnologia de suporte a visitas. Em particular, investigou-se até que ponto uma personagem virtual pode desempenhar funções próximas daquelas que normalmente se atribuem a um guia Humano, ou seja, ser capaz de acompanhar pequenos grupos, transmitindo em cada ponto da visita as informações adequadas a esse local. Como principal conclusão foi identificado que o cenário em que a utilização deste tipo de sistemas se poderá mostrar mais vantajosa será no caso de visitas de estudo com professores, ou outras em que um dos elementos do grupo, mesmo não conhecendo o museu, tem objectivos de ensino para com os restantes. Nesse caso, a não existência de um guia Humano tem como vantagem potencial permitir ao grupo de visitantes definir o seu ritmo de visita e ao mesmo tempo facilita o contacto social entre os elementos do grupo, que é um factor bastante importante para a aprendizagem. O sistema aproveita as potencialidades de comunicação das personagens virtuais para transmitir a informação, mas o facto de não exigir um guia Humano a narrar o guião dá alguma liberdade aos vários elementos para terem conversas informais sobre os conteúdos da visita.

avisos de segurança

description: Este estudo teve como objectivo principal a avaliação da interacção com Envolvimentos Virtuais (EVs) através de matrizes de exploração do espaço. As matrizes são o resultado da exploração de um EV, com dois níveis de poluição visual, onde foram aplicados dois tipos de avisos de segurança, estáticos e dinâmicos, tendo ainda sido considerada uma condição de controlo. Participaram neste estudo 150 indivíduos, 30 em cada uma de 5 condições experimentais, aos quais foi pedido que efectuassem uma tarefa, relacionada com avisos de segurança, que implicava a procura de botões distribuídos por diversas zonas do EV. Partindo do pressuposto que os avisos mais salientes (dinâmicos) seriam detectados mais facilmente, foi colocada a hipótese de que existiriam diferenças na exploração do espaço e que essas diferenças estariam reflectidas nas matrizes. O sistema de Realidade Virtual (RV) imersiva – ErgoVR – recolheu automaticamente diversos dados da interacção, entre os quais se destacam a posição do participante no EV, os tempos e as distâncias percorridas. Esses dados permitiram gerar matrizes de exploração do espaço, por condição experimental, contendo indicação das quadrículas pisadas e a frequência com que o foram. O ''acordo”'' da exploração espacial, nas 5 condições experimentais, foi avaliado através da aplicação do Coeficiente de Correlação de Concordância sobre as frequências com que as quadrículas foram pisadas. Os resultados obtidos revelam valores bastante elevados de ''acordo'' entre as matrizes, o que permite afirmar que a exploração do espaço no EV não foi fortemente influenciada pela condição experimental.

description: We study the interactions between the coherent quasiparticles and the incoherent Mott-Hubbard excitations and their effects on the low energy properties in the $U=\infty$ Hubbard model. Within the framework of a systematic large-N expansion, these effects first occur in the next to leading order in 1/N. We calculate the scattering phase shift and the free energy, and determine the quasiparticle weight Z, mass renormalization, and the compressibility. It is found that the compressibility is strongly renormalized and diverges at a critical doping $δ_c=0.07\pm0.01$. We discuss the nature of this zero-temperature phase transition and its connection to phase separation and superconductivity.

description: A experiência de utilização de ambiente ubíquos é um factor determinante no seu sucesso. As características de tais sistemas devem ser exploradas o mais cedo possível para antecipar potenciais problemas de utilização por parte do utilizador e para reduzir custos de re-design. No entanto, o desenvolvimento antecipado de prot´otipos a serem avaliados no ambiente final pode ser disruptivo e tornar-se inaceitável. O desenvolvimento de prot´otipos de ambientes ubíquos pode ajudar, fornecendo indicações de como o utilizador irá reagir perante os ambientes. Este artigo descreve o APEX, uma plataforma de prototipagem rápida de ambientes ubíquos que junta a CPN Tools com um servidor de aplicações 3D existente. Os prot´otipos desenvolvidos com o APEX permitem que os utilizadores naveguem num mundo virtual, podendo experimentar muitas das características do design proposto. A arquitectura do APEX e a modelação baseada em CPN s˜ao descritas. Um exemplo ilustra a abordagem.

locomoção virtual e ambientes virtuais

description: A navegação é uma das tarefas principais que os utilizadores podem realizar nos ambientes virtuais 3D. Muitas técnicas, metáforas e dispositivos de interacção têm sido desenhados, implementados e avaliados nesta área da Interacção Pessoa/Computador. Inicialmente, foram usados métodos de interacção indirecta para controlar a navegação, baseados no uso de controlos virtuais e físicos, mas, actualmente, os métodos inovadores que têm sido mais comummente investigados são suportados em interacção directa, conduzida pela acção do controlo de partes do corpo do utilizador, como a cabeça, o tronco, os braços/mãos e as pernas/pés. Este artigo descreve uma abordagem de uma técnica de navegação virtual denominada ''Caminhar no Lugar''que permite a um utilizador controlar a velocidade de deslocamento do avatar. Fizeram-se experiências para determinar uma forma de cálculo genérica da velocidade instantânea da locomoção horizontal virtual baseada na velocidade vertical dos pés do utilizador ao caminhar no lugar, através do correlacionamento com a velocidade horizontal do utilizador no caminhar real. Os resultados obtidos permitiram determinar uma fórmula do cálculo da velocidade horizontal virtual para cada tipo de passo (devagar, moderado e rápido) e uma outra mais genérica e independente do tipo de passo.

description: A cross-sectional survey study was undertaken to describe the perceived competence, pre- and post-professional training, and practice of Filipino speech-language pathologists (SLPs) in augmentative and alternative communication (AAC). Printed and electronic questionnaires were distributed to all SLPs in the Philippines with at least 1 year of practice experience. A total of 152 (47%) questionnaires were returned. Based on these data, 108 respondents (71%) practiced AAC, but most (range = 59–89%) did not perceive themselves to be competent in working with various client populations with complex communication needs. A majority (range = 70–93%) of the respondents reported limited pre-professional training in all AAC content areas, and at least 82% strongly desired continuing education in almost all areas of AAC. Almost 90% of respondents only occasionally (53%) or rarely (36%) recommended AAC, and 82% considered it as a last resort. Major practice challenges reported were families’ negative attitudes toward AAC and lack of AAC-specific interdisciplinary collaboration. Infrequent use of high-tech AAC was also reported. The findings suggest various ways through which AAC education and services in the Philippines may be enhanced. They also imply the need for further research on alternative service delivery models, as well as additional members of the AAC team.
On identifying magnetized anomalies using geomagnetic monitoring II. A Magnetohydrodynamic Model

description: This paper is a continuation and an extension of our recent work [13] on the identification of magnetized anomalies using geomagnetic monitoring, which aims to establish a rigorous mathematical theory for the geomagnetic detection technology. Suppose a collection of magnetized anomalies is presented in the shell of the Earth. By monitoring the variation of the magnetic field of the Earth due to the presence of the anomalies, we establish sufficient conditions for the unique recovery of those unknown anomalies. In [13], the geomagnetic model was described by a linear Maxwell system. In this paper, we consider a much more sophisticated and complicated magnetohydrodynamic model, which stems from the widely accepted dynamo theory of geomagnetics.
Diffusion in a strongly correlated anisotropic overlayer

description: We study the collective diffusion in chain structures on anisotropic substrates like (112) bcc and (110) fcc surfaces with deep troughs in the substrate potential corrugation. These chain structures are aligned normal to the troughs and can move only along the troughs. In a combination of theoretical arguments and of numerical simulations, we study the mass transport in these anisotropic systems. We find that a mechanism similar to soliton diffusion, instead of single particle diffusion, is still effective at temperatures well above the melting temperature of the ordered chain structures. This mechanism is directly correlated with the ordered phases that appear at much lower temperatures. As a consequence, also the influence of frozen disorder is still visible above the melting temperature. Theoretically we predict a strong dependence of the pre-exponential factor and weak dependence of the activation energy on the concentration of frozen surface defects. These predictions are confirmed by the simulations.
