title: Self And Relative Reported Executive Dysfunction In Multiple Sclerosis: Prevalence And Relationship With Mood And Health Status
Creators: name: Atkins, Elisabeth Anice
Publisher: name: The Open University
Year: 2002

description: Introduction
Research indicates that cognitive impairment in multiple sclerosis (MS) may occur in approximately half of cases and may have detrimental effects on an individual’s general health status and mood. This study explores the usefulness of subjective measures of cognitive impairment in enhancing our knowledge of the relationships between these variables. Of particular interest was the self-reporting of executive dysfunction, an under-researched area in MS.

 Method
One hundred and forty-seven individuals with MS completed a postal questionnaire survey measuring self-reported memory impairment, executive dysfunction, mood and health status. Eighty-two of their relatives completed a postal questionnaire survey, rating the patients’ memory impairment and executive dysfunction. Comparative samples were a traumatic brain injury (TBI) population and healthy controls.

 Results
The amount of executive dysfunction reported by patients was lower than in a TBI population but not significantly different from that reported by healthy controls. Relatives reported lower levels of executive dysfunction than in a TBI population but significantly higher levels than healthy controls. There was no significant difference between patient and relatives’ reports of executive dysfunction in the group overall but detailed analyses highlighted sub-groups where significant differences were found. The sample was split into individuals who over-report and under-report executive difficulties in comparison to their relatives. Over-reporters were found to be more likely to have relapsing-remitting MS, report higher levels of anxiety, report higher levels of memory impairment and have lower levels of relative-reported memory impairment, compared to under-reporters. The discrepancy score (a tendency to over-report executive dysfunction) was also found to be a predictor of depression. Subjective reports of cognitive impairment were not found to predict health status (measured by social functioning and employment status). However, self-reports of executive dysfunction were found to be the strongest predictors of depression and anxiety.

 Conclusions
 These results are interpreted and possible implications for theory and clinical practice suggested. The findings highlight relationships between subjective reports of cognitive impairment and mood and health status that have not been investigated before in MS. A number of hypotheses are proposed for the relationship between these variables, but clarification of these relationships is not possible in the current design. Therefore, avenues are suggested for future research.

description: We study the relation between the coregularity, the index of log Calabi-Yau pairs, and the complements of Fano varieties. We show that the index of a log Calabi-Yau pair $(X,B)$ of coregularity $1$ is at most $120λ^2$, where $λ$ is the Weil index of $K_X+B$. This extends a recent result due to Filipazzi, Mauri, and Moraga. We prove that a Fano variety of absolute coregularity $0$ admits either a $1$-complement or a $2$-complement. In the case of Fano varieties of absolute coregularity $1$, we show that they admit an $N$-complement with $N$ at most 6. Applying the previous results, we prove that a klt singularity of absolute coregularity $0$ admits either a $1$-complement or $2$-complement. Furthermore, a klt singularity of absolute coregularity $1$ admits an $N$-complement with $N$ at most 6. This extends the classic classification of $A,D,E$-type klt surface singularities to arbitrary dimensions. Similar results are proved in the case of coregularity $2$. In the course of the proof, we prove a novel canonical bundle formula for pairs with bounded relative coregularity. In the case of coregularity at least $3$, we establish analogous statements under the assumption of the index conjecture and the boundedness of B-representations.

description: We present version 1.0 of the ISOGAL-DENIS Point Source Catalogue (PSC), containing more than 100,000 point sources detected at 7 and/or 15 micron in the ISOGAL survey of the inner Galaxy with the ISOCAM instrument on board the Infrared Space Observatory (ISO). These sources are cross-identified, wherever possible, with near-infrared (0.8-2.2 micron) data from the DENIS survey. The overall surface covered by the ISOGAL survey is about 16 square degrees, mostly (95%) distributed near the Galactic plane (|b| < 1 deg), where the source extraction can become confusion limited and perturbed by the high background emission. Therefore, special care has been taken aimed at limiting the photometric error to ~0.2 magnitude down to a sensitivity limit of typically 10 mJy. The present paper gives a complete description of the entries and the information which can be found in this catalogue, as well as a detailed discussion of the data processing and the quality checks which have been completed. The catalogue is available via the VizieR Service at the Centre de Données Astronomiques de Strasbourg (CDS, http://vizier.u-strasbg.fr/viz-bin/VizieR/) and also via the server at the Institut d'Astrophysique de Paris (http://www-isogal.iap.fr/). A more complete version of this paper, including a detailed description of the data processing, is available in electronic form through the ADS service.

description: High-quality surface normal can help improve geometry estimation in problems faced by autonomous vehicles, such as collision avoidance and occlusion inference. While a considerable volume of literature focuses on densely scanned indoor scenarios, normal estimation during autonomous driving remains an intricate problem due to the sparse, non-uniform, and noisy nature of real-world LiDAR scans. In this paper, we introduce a multi-modal technique that leverages 3D point clouds and 2D colour images obtained from LiDAR and camera sensors for surface normal estimation. We present the Hybrid Geometric Transformer (HGT), a novel transformer-based neural network architecture that proficiently fuses visual semantic and 3D geometric information. Furthermore, we developed an effective learning strategy for the multi-modal data. Experimental results demonstrate the superior effectiveness of our information fusion approach compared to existing methods. It has also been verified that the proposed model can learn from a simulated 3D environment that mimics a traffic scene. The learned geometric knowledge is transferable and can be applied to real-world 3D scenes in the KITTI dataset. Further tasks built upon the estimated normal vectors in the KITTI dataset show that the proposed estimator has an advantage over existing methods.

description: The feasibility of a measurement of the electric and magnetic nucleon form factors at $B$-meson factories through the radiative return is studied. Angular distributions allow a separation of the contributions from the two form factors. The distributions are presented for the laboratory and the hadronic rest frame, and the advantages of different coordinate systems are investigated. It is demonstrated that $Q^2$ values up to 8 or even 9 GeV$^2$ are within reach. The Monte Carlo event generator PHOKHARA is extended to nucleon final states, and results are presented which include Next-to-Leading Order radiative corrections from initial-state radiation. The impact of angular cuts on rates and distributions is investigated and the relative importance of radiative corrections is analysed.

description: We consider a class of \textit{factorizable} Poisson brackets which includes almost all reasonable Poisson structures. A particular case of the factorizable brackets are those associated with symplectic Lie algebroids. The BRST theory is applied to describe the geometry underlying these brackets as well as to develop a deformation quantization procedure in this particular case. This can be viewed as an extension of the Fedosov deformation quantization to a wide class of \textit{irregular} Poisson structures. In a more general case, the factorizable Poisson brackets are shown to be closely connected with the notion of $n$-algebroid. A simple description is suggested for the geometry underlying the factorizable Poisson brackets basing on construction of an odd Poisson algebra bundle equipped with an abelian connection. It is shown that the zero-curvature condition for this connection generates all the structure relations for the $n$-algebroid as well as a generalization of the Yang-Baxter equation for the symplectic structure.

description: We present scanning-probe images and magnetic-field plots which reveal fractal conductance fluctuations in a quantum billiard. The quantum billiard is drawn and tuned using erasable electrostatic lithography, where the scanning probe draws patterns of surface charge in the same environment used for measurements. A periodicity in magnetic field, which is observed in both the images and plots, suggests the presence of classical orbits. Subsequent high-pass filtered high-resolution images resemble the predicted probability density of scarred wave functions, which describe the classical orbits.

description: We study contributions to the Delta S=2 weak Chiral Lagrangian producing K0-K0bar mixing which are not enhanced by the charm mass. For the real part, these contributions turn out to be related to the box diagram with up quarks but, unlike in perturbation theory, they do not vanish in the limit m_u->0. They increase the leading contribution to the K_L-K_S mass difference by ~10%. This means that short distances amount to (90+-15)% of this mass difference. For the imaginary part, we find a correction to the lambda_c^2 m_c^2 term of -5% from the integration of charm, which is a small contribution to epsilon_K. The calculation is done in the large-Nc limit and we show explicitly how to match short and long distances.

This project is a continuation of a previous year capstone project which UBC PAS wanted us to improve upon their design. The designed product will be installed in areas where stall flexibility is needed. UBC PAS will have access to an online management system to remotely control what is displayed on the sign and monitor the status of each sign. The final product will feature a programmable display showing parking information. It will be powered by rechargeable batteries and a solar panel. This document records all choices of components our team made in order to fulfill the functional and non-functional requirements while adhering to the constraints of this project.

description: We present an analysis of a Chandra observation of Abell 2034. The cluster has multiple signatures of an ongoing merger, including a cold front and probable significant heating of the intracluster medium above its equilibrium temperature. We find no evidence for the large cooling rate previously determined for the cluster, and in fact find it to be roughly isothermal, though with numerous small-scale inhomogeneities, out to a radius of ~700 kpc. The cold front appears to be in the process of being disrupted by gas dynamic instability and perhaps by shock heating. We find weak evidence for Inverse Compton hard X-ray emission from the radio relic suspected to be associated with the cold front. Finally, we study the emission to the south of the cluster, which was previously thought to be a merging subcluster. We find no evidence that this "subcluster" is interacting with the main Abell 2034 cluster. On the other hand, the properties of this region are inconsistent with an equilibrium cluster at the redshift of Abell 2034 or less. We explore the possibility that it is a disrupted merging subcluster, but find its luminosity to be significantly lower than expected for such a scenario. We suggest that the emission to the south of the cluster may actually be a moderate to high redshift (0.3 < z < 1.25) background cluster seen in projection against Abell 2034.

description: We are concerned with a class of second order quasilinear elliptic equations driven by a nonhomogeneous differential operator introduced by C.A. Stuart and whose study is motivated by models in Nonlinear Optics. We establish sufficient conditions for the existence of at least one or two non-negative solutions. Our analysis considers the cases when the reaction has either a sublinear or a linear growth. In the sublinear case, we also prove a nonexistence property. The proofs combine energy estimates and variational methods. In particular, the monotonicity trick is applied in order to overcome the lack of a priori bounds on the Palais-Smale sequences.

description: [abridged] We have assembled a database of stars having both masses determined from measured orbital dynamics and sufficient spectral and photometric information for their placement on a theoretical HR diagram. Our sample consists of 115 low mass (M < 2.0 Msun) stars, 27 pre-main sequence and 88 main sequence. We use a variety of available pre-main sequence evolutionary calculations to test the consistency of predicted stellar masses with dynamically determined masses. Despite substantial improvements in model physics over the past decade, large systematic discrepancies still exist between empirical and theoretically derived masses. For main-sequence stars, all models considered predict masses consistent with dynamical values above 1.2 Msun, some models predict consistent masses at solar or slightly lower masses, and no models predict consistent masses below 0.5 Msun but rather all models systematically under-predict such low masses by 5-20%. The failure at low masses stems from the poor match of most models to the empirical main-sequence below temperatures of 3800 K where molecules become the dominant source of opacity and convection is the dominant mode of energy transport. For the pre-main sequence sample we find similar trends. There is generally good agreement between predicted and dynamical masses above 1.2 Msun for all models. Below 1.2 Msun and down to 0.3 Msun (the lowest mass testable) most evolutionary models systematically under-predict the dynamically determined masses by 10-30% on average with the Lyon group models (e.g. Baraffe et al. 1998) predicting marginally consistent masses *in the mean* though with large scatter.

description: The center of M83, a barred starburst galaxy with a double nucleus, has been observed in the CO(J=2-1) and CO(J=3-2) lines with the Submillimeter Array. The molecular gas shows a distribution and kinematics typical for barred galaxies at kpc radii, but reveals unusual kinematics around the double nucleus in the central 300 pc. Our CO velocity data show that the visible nucleus in M83 is at least 3" (65 pc) away from the galaxy's dynamical center, which most likely coincides with the center of symmetry previously determined in K band and is suggested to host another nucleus. We discovered high-velocity molecular gas associated with the visible off-center nucleus, and also found a steep velocity gradient across it. We attribute these features to a gas disk rotating around the off-center nucleus, which may be the remnant of a small galaxy accreted by M83. The dynamical mass of this component is estimated to be 3x10^8 Msun within a radius of 40 pc. The dynamical perturbation from the off-center nucleus may have played a key role in shaping the lopsided starburst.

description: O tema das Humanidades Digitais têm sido recorrentemente procurado no Brasil. Apesar da retórica da interdisciplinaridade estar presente na maioria das iniciativas de pesquisa a prática nos mostra que a interdisciplinaridade cessa sua abrangência real quando o assunto se trata de acesso à informação e de reuso de dados por vezes mineirados por ferramentas e métodos interdisciplinares por natureza. Após o digital turn o cenário acadêmico precisou reencontrar-se no que tange às suas estratégias de preservação e de uso da informação científica para a continuidade da produção do conhecimento e da promoção ao seu acesso. Nesse escopo, criamos o Laboratório em Rede de Humanidades Digitais (Larhud) e tal fato igualmente nos convidou a pensar sobre um repositório capaz de guardar e preservar dados brutos (raw data) provenientes da pesquisa em humanidades de maneira a promover seu acesso pela comunidade científica possibilitando, entre outras coisas, seu acompanhamento, a troca de informações além de, consequentemente, a geração de inovação e de novos conteúdos. Neste artigo tratamos do processo de produção de ambos: laboratório e repositório enquanto partes intrínsecas para as atividades em andamento, além de suscitar reflexões de ordem epistemológica e metodológica.

description: Limitations to the speed of evolution of quantum systems, typically referred to as quantum speed limits (QSLs), have important consequences for quantum control problems. However, in its standard formulation, is not straightforward to obtain meaningful QSL bounds for time-dependent Hamiltonians with unknown control parameters. In this paper we present a short introductory overview of quantum speed limit for unitary dynamics and its connection to quantum control. We then analyze potential methods for obtaining new bounds on control times inspired by the QSL. We finally extend the work in [Poggi, Lombardo and Wisniacki EPL 104 40005 (2013)] by studying the properties and limitations of these new bounds in the context of a driven two-level quantum system

description: Controlling the electronic properties via bandstructure engineering is at the heart of modern semiconductor devices. Here, we extend this concept to semimetals where, utilizing LuSb as a model system, we show that quantum confinement lifts carrier compensation and differentially affects the mobility of the electron and hole-like carriers resulting in a strong modification in its large, non-saturating magnetoresistance behavior. Bonding mismatch at the heteroepitaxial interface of a semimetal (LuSb) and a semiconductor (GaSb) leads to the emergence of a novel, two-dimensional, interfacial hole gas and is accompanied by a charge transfer across the interface that provides another avenue to modify the electronic structure and magnetotransport properties in the ultra-thin limit. Our work lays out a general strategy of utilizing confined thin film geometries and heteroepitaxial interfaces to engineer electronic structure in semimetallic systems, which allows control over their magnetoresistance behavior and simultaneously, provides insights into its origin.

title: Understanding the factors that influence the provision of 1:1 care in residential homes for older adults : an application of the theory of planned behaviour
Creators: name: Rollinson, Rebecca
Publisher: name: The Open University
Year: 2001

description: Objectives To use the theory of planned behaviour to explore the factors affecting the decision of professional carers to provide 1:1 care in residential homes for older adults. Design A cross sectional survey design was used to assess 102 carers in 17 residential homes. A small sample returned a repeat assessment allowing a longitudinal examination of the relationship between intention and actual behaviour. Methods A questionnaire was written in accordance with the theory of planned behaviour guidelines and developed through interviews with carers. Standardised questionnaires were used to assess resident ability, perceived involvement in decision making and the extent to which the homes were resident or institution focused. Results On average, carers intended to spend 27 to 45 minutes per shift providing 1:1 care. Perceived behavioural control was the strongest predictor of intention (accounting for 34% of the variance). Low resident ability level correlated with low perceived behavioural control and predicted a lower intention to provide 1:1 care. Perceived involvement correlated with perceived behavioural control but was not predictive of intention. Past behaviour retained predictive ability once the theory of planned behaviour components were accounted for. Conclusions Residential carers perceive factors within the resident and the organisation as barriers to 1:1 care. Carers may be less likely to provide 1:1 care to residents with lower ability levels, although methodological limitations restrict the conclusions that can be drawn. Future research could usefully consider the potentially habitual nature of 1:1 care.

Stellar tracers of the Cygnus Arm I. Spectroscopic study of bright photometric candidates

description: We present medium-resolution spectroscopy of a sample of stars in the second Galactic quadrant selected from the literature because their colours suggest that they are moderately-reddened early-type stars at very large distances. From the derived spectral types and observed colours, we calculate distances to all these objects. For a sizable fraction of our sample, we find distances well in excess of what is expected for Perseus Arm objects, even allowing for rather generous errors. In the interval l=150degr-180degr, there is a large number of objects with distances in excess of 4 kpc, which are likely tracing the Outer or Cygnus Arm. In particular, we find that the association Cam OB3 is placed on this Arm. Based on our results, the extent and definition of the associations Cas OB4 and Aur OB2 need to be reevaluated.

description: We consider in detail the situation of applying a time dependent external magnetic field to a 87Rb atomic Bose-Einstein condensate held in a harmonic trap, in order to adiabatically sweep the interatomic interactions across a Feshbach resonance to produce diatomic molecules. To this end, we introduce a minimal two-body Hamiltonian depending on just five measurable parameters of a Feshbach resonance, which accurately determines all low energy binary scattering observables, in particular, the molecular conversion efficiency of just two atoms. Based on this description of the microscopic collision phenomena, we use the many-body theory of T. Koehler and K. Burnett [Phys. Rev. A 65, 033601 (2002)] to study the efficiency of the association of molecules in a 87Rb Bose-Einstein condensate during a linear passage of the magnetic field strength across the 100 mT Feshbach resonance. We explore different, experimentally accessible, parameter regimes, and compare the predictions of Landau-Zener, configuration interaction, and two level mean field calculations with those of the microscopic many-body approach. Our comparative studies reveal a remarkable insensitivity of the molecular conversion efficiency with respect to both the details of the microscopic binary collision physics and the coherent nature of the Bose-Einstein condensed gas, provided that the magnetic field strength is varied linearly. We provide the reasons for this universality of the molecular production achieved by linear ramps of the magnetic field strength, and identify the Landau-Zener coefficient determined by F.H. Mies et al. [Phys. Rev. A 61, 022721 (2000)] as the main parameter that controls the efficiency.

description: A presente comunicação se apresenta como uma contribuição teorico-metodológica para os estudos de altmetria com abordagem qualitativa para análise das condições de interação das menções a um conjunto de artigos científicos sobre políticas públicas. Os dados foram coletados via Dimensions.api com busca por artigos em acesso aberto em consultas pelos termos “bolsa família” e “bolsa escola”. Ao todo foram identificados 344 artigos e 275 dados altmétricos publicados entre 2010 e 2017. Buscando enfatizar as redes e arenas que se formam em torno das políticas públicas, foi possível perceber que apesar da grande quantidade de pessoas não-especialistas compartilhando o conteúdo científico, estes usuários formam micro-clusters isolados, enquanto comunicadores da ciência, cientistas atuantes na área de políticas públicas e saúde marcam sua autoridade sobre o assunto em suas redes sociais, mostrando a relevância destes profissionais na comunicação de políticas públicas pela ciência. A partir de um estudo qualitativo, foi possível observar ainda que quando se trata de políticas públicas, uma outra categoria de menções foi identificada a partir de manifestações ideológicas dos usuários, sendo utilizada como argumento de disputas políticas nas redes sociais.

description: Acredita-se que os resultados e impactos dos avanços científicos e tecnológicos resultantes das atividades das instituições públicas de pesquisa devem ser amplamente disseminados e compartilhados, a fim de promover múltiplos caminhos de socialização com a comunidade em geral. O objetivo deste trabalho é apresentar como boas práticas de divulgação científica o evento "Café com Ciência", realizado na sala de leitura da Biblioteca Embrapa Amapá. Neste evento, os resultados da pesquisa são apresentados na forma de publicações da série Embrapa, recentemente publicadas e disponíveis em acesso aberto no Repositório de Informações da Embrapa, e são discutidas de forma prática, informal e descontraída. O evento teve início em 2017, ano em que foram realizadas quatro sessões, entre agosto e dezembro. Colaboradores da Embrapa Amapá (bolsistas e trainees) participaram, além de professores e alunos de universidades e outras instituições de ensino e pesquisa da região. Um dos principais resultados do evento é a disseminação e divulgação de informações e conhecimentos gerados na Embrapa Amapá, que consequentemente repercutem nas estatísticas de acesso (consultas e downloads) dos documentos disponíveis na Infoteca-e e no repositório.
