description: We studied the electronic properties of beta-platinum dioxide (β-PtO2), a catalytic material, based on density functional theory. Using the GGA+U method which reproduces the GW band structures and the experimental structural parameters, we found that the creation of an oxygen vacancy will induce local magnetic moment on the neighboring Pt and O atoms. The magnetism originates not only from the unpaired electrons that occupy the vacancy induced gap state, but also from the itinerant valence electrons. Because of antiferromagnetic (AF) coupling and the localized nature of gap states, the total magnetic moment is zero for charge-neutral state (V_o^0) and is ~ 1 μB for singly-charged states (V_o^μ). Calculation of grand potential shows that, the three charge states (V_o^0, V_o^\pm) are of the same stability within a small region, and the negatively charged state (V_o^-) is energetically favored within a wide range of the band gap. On this basis we discussed the implication on catalytic behavior.

description: Neutral atomic Bose condensates and degenerate Fermi gases have been used to realize important many-body phenomena in their most simple and essential forms, without many of the complexities usually associated with material systems. However, the charge neutrality of these systems presents an apparent limitation - a wide range of intriguing phenomena arise from the Lorentz force for charged particles in a magnetic field, such as the fractional quantum Hall states in two-dimensional electron systems. The limitation can be circumvented by exploiting the equivalence of the Lorentz force and the Coriolis force to create synthetic magnetic fields in rotating neutral systems. This was demonstrated by the appearance of quantized vortices in pioneering experiments on rotating quantum gases, a hallmark of superfluids or superconductors in a magnetic field. However, because of technical issues limiting the maximum rotation velocity, the metastable nature of the rotating state and the difficulty of applying stable rotating optical lattices, rotational approaches are not able to reach the large fields required for quantum Hall physics. Here, we experimentally realize an optically synthesized magnetic field for ultracold neutral atoms, made evident from the appearance of vortices in our Bose-Einstein condensate. Our approach uses a spatially-dependent optical coupling between internal states of the atoms, yielding a Berry's phase sufficient to create large synthetic magnetic fields, and is not subject to the limitations of rotating systems; with a suitable lattice configuration, it should be possible to reach the quantum Hall regime, potentially enabling studies of topological quantum computation.

description: La realtà ci consegna, oggi, la descrizione di una adolescenza sempre piu’ isolata ed iperconnessa, ossessionata dal desiderio di apparire, comunicando per detta via una esasperata insicurezza e solitudine. La famiglia non sempre è in grado di accompagnare i figli adolescenti nel percorso di crescita e di riconoscerne i bisogni ed essi rischiano di sentirsi smarriti e privati di punti di riferimento. La scuola rappresenta spesso la prima occasione di conoscere se’ stessi in totale libertà. Il presente studio ha l’obiettivo di evidenziare, alla luce dei numerosi contributi esistenti, l’importanza di una relazione educativa docente- allievo positiva, improntata alla comunicazione e al rispetto dell’allievo - individuo, affinché l’aula di classe possa essere luogo di responsabilizzazione, consapevolezza e maturazione, di acquisizione di saperi ma prima di tutto di accoglienza e accettazione.

Conceptualizing patient-centered care in injectable opioid agonist treatment : a multi-methods study of patients' experiences and satisfaction with treatment
Creators: name: Marchand, Kirsten

description: Opioid use disorder (OUD) is a chronic health condition that exposes people to harms (e.g., overdoses) that can be mitigated by treatments, such as oral methadone. For people not benefitting from such oral treatments, evidence supports the use of injectable opioid agonist treatment (iOAT) with diacetylmorphine or hydromorphone, which has recently begun expanding in Canada. While iOAT was rigorously tested in clinical trials, research questions were motivated towards testing the effectiveness of medications. This leaves critical questions about other salient attributes of iOAT (e.g., daily interactions with health care providers) and patients’ experiences when iOAT is offered as a regular clinical program. Addressing these gaps was the broader aim of this research. This multi-method research was conducted alongside a longitudinal cohort study of people with OUD who were currently or previously receiving iOAT in Canada’s first clinical program. A qualitative study explored participants’ experiences in iOAT as they related to patient-centered care (i.e., holistic care, individualized care, collaborative care, therapeutic relationships). Next, a thematic analysis was conducted on eight waves of participants’ positive and negative perceptions of iOAT. These studies supported framework development for a quantitative analysis of participants’ treatment satisfaction trajectories and its relationship with patient and program characteristics. The qualitative research revealed two inter-related processes: ‘meeting me where I am’ highlighted participants’ initial reasons for seeking iOAT and the unique unraveling of individualized and holistic care needs. The second process ‘building health care provider relationships’ revealed the significance of therapeutic relationships and how these were formed through “opening up” and “being a part of care”. The salience of therapeutic relationships was also shown in the thematic analysis, where they represented 23% of positive and 12% of negative comments overall. The analysis of treatment satisfaction trajectories determined that the extent of drug liking and unfavorable health care provider interactions held the strongest independent effects on overall satisfaction over time. This research demonstrated that therapeutic relationships played a fundamental role in participants’ unique iOAT needs and treatment satisfaction over time. These findings urge an expanded vision of treatment implementation and monitoring for OUD.

description: We consider Hamiltonian systems with symmetry, and relative equilibria with isotropy subgroup of positive dimension. The stability of such relative equilibria has been studied by Ortega and Ratiu and by Lerman and Singer. In both papers the authors give sufficient conditions for stability which require first determining a splitting of a subspace of the Lie algebra of the symmetry group, with different splittings giving different criteria. In this note we remove this splitting construction and so provide a more general and more easily computed criterion for stability. The result is also extended to apply to systems whose momentum map is not coadjoint equivariant.

description: We present a concept study on weak lensing map reconstruction through the cosmic magnification effect in galaxy number density distribution. We propose a minimal variance linear estimator to minimize both the dominant systematical and statistical errors in the map reconstruction. It utilizes the distinctively different flux dependences to separate the cosmic magnification signal from the overwhelming galaxy intrinsic clustering noise. It also minimizes the shot noise error by an optimal weighting scheme on the galaxy number density in each flux bin. Our method is in principle applicable to all galaxy surveys with reasonable redshift information. We demonstrate its applicability against the planned Square Kilometer Array survey, under simplified conditions. Weak lensing maps reconstructed through our method are complementary to that from cosmic shear and CMB and 21cm lensing. They are useful for cross checking over systematical errors in weak lensing reconstruction and for improving cosmological constraints.

description: O presente estudo incide sobre as eleições suplementares de 1913. Aborda os tópicos referentes aos partidos políticos nesta região, elite política local, escolha dos candidatos, campanha eleitoral e resultados eleitorais. As eleições suplementares de 1913 foram o primeiro grande combate político e partidário do Alentejo após a implantação da República. Estas eleições foram disputadas pelas principais forças políticas que se estabeleceram de forma diferente em cada distrito alentejano. Apesar da influência local de Brito Camacho e do seu partido, estas eleições demonstraram a hegemonia crescente do Partido Republicano Português que se tornou o maior partido na região e no país até 1926.

description: Services oriented grids will be more prominent among other kinds of grids in the present distributed environments. With the advent of online government services the governmental grids will come up in huge numbers. Apart from common security issues as in other grids, the authorization in service oriented grids faces certain shortcomings and needs to be looked upon differently. The CMMS model presented here overcomes all these shortcomings and adds to the simplicity of implementation because of its tight similarities with certain government services and their functioning. The model is used to prototype a State Police Information Grid (SPIG). Small technological restructuring is required in PKIX and X.509 certificates.
A História Local no mundo das Humanidades Digitais. O estudo de caso das elites políticas covilhanenses

description: Pretende-se analisar o impacto que as humanidades digitais têm naquilo que é a nova historiografia para a história local. Esta nova visão historiográfica vai influenciar novas abordagens do conceito de elite, a partir do programa designado de Gephi. Este programa é um instrumento que permite analisar uma rede, isto é, trata-se de uma ferramenta de código aberto que permite a observação de conexões que serão designadas pelas pessoas. Numa linguagem académica de redes, o conceito de nós (nodes) define-se como uma representação de um indivíduo, e, por sua vez, chama-se conexões (edges) há linha que há entre essa pessoa e o indivíduo. Para a investigação em ciências sociais e humanas, esta ferramenta tem um grande interesse, uma vez que permite a transversalidade entre várias áreas. Para exemplificar esta análise historiográfica, iremos analisar as elites políticas covilhanenses, que através dos polos político administrativos, como o caso da Santa Casa da Misericórdia e da Câmara Municipal, a par da sua participação do mundo associativista, como é o caso do Clube União e do Ginásio Clube da Covilhã, irá ser construído uma rede, a partir do programa referido, e iremos proceder à sua análise com alguns conceitos provenientes das humanidades digitais.

description: A transição entre Antigo Regime e o Liberalismo significou uma alteração profunda nos modelos de representação política e social. Se no passado no acesso aos lugares de destaque se privilegiava o nascimento e a predominância social da chamada “gente da governança”, com o poder económico baseado na posse da terra, o Liberalismo apostou na meritocracia, promovendo outras formas de acumular fortuna. Porém, as continuidades foram evidentes e as antigas elites souberam adaptar-se, aumentando o seu poder económico, político e social. Foram estes os casos das famílias dos Vaz Preto e Tavares Proença na Beira Baixa.

name: Savoji, Mohammad H.

Year: 2011

description: A fast, efficient and scalable algorithm is proposed, in this paper, for re-encoding of perceptually quantized wavelet-packet transform (WPT) coefficients of audio and high quality speech and is called "adaptive variable degree-k zero-trees" (AVDZ). The quantization process is carried out by taking into account some basic perceptual considerations, and achieves good subjective quality with low complexity. The performance of the proposed AVDZ algorithm is compared with two other zero-tree-based schemes comprising: 1- Embedded Zero-tree Wavelet (EZW) and 2- The set partitioning in hierarchical trees (SPIHT). Since EZW and SPIHT are designed for image compression, some modifications are incorporated in these schemes for their better matching to audio signals. It is shown that the proposed modifications can improve their performance by about 15-25%. Furthermore, it is concluded that the proposed AVDZ algorithm outperforms these modified versions in terms of both output average bit-rates and computation times.

description: The evolution of the ground state wave function of a zero-temperature Bose-Einstein condensate (BEC) is well described by the Hamiltonian Gross-Pitaevskii (GP) equation. Using a set of appropriately interleaved unitary collision-streaming operators, a quantum lattice gas algorithm is devised which on taking moments recovers the Gross-Pitaevskii (GP) equation in diffusion ordering (time scales as square of length). Unexpectedly, there is a class of initial conditions in which their Poincare recurrence is extremely short. Further it is shown that the Poincare recurrence time scales with diffusion ordering as the the grid is increased. The spectral results of Yepez et.al. [1] for quantum turbulence are corrected and it is found that it is the compressible kinetic energy spectrum that exhibits the 3 cascade regions: a small k classical Kolmogorov k^(-5/3) spectrum, a steep semi-classical cascade region, and a large k quantum Kelvin wave cascade k^(-3) spectrum. The incompressible kinetic energy spectrum exhibits basically a single cascade power law of k^(-3). For winding number 1 linear vortices it is also shown that there is an intermittent loss of Kelvin wave cascade with its signature seen in the time evolution of the kinetic energy, the loss of the k^(-3) spectrum in the incompressible kinetic energy spectrum as well as the minimization of the vortex core isosurfaces that inhibits the Kelvin wave cascade.

description: A method is proposed for measuring the size of the broad emission line region (BLR) in quasars using broadband photometric data. A feasibility study, based on numerical simulations, points to the advantages and pitfalls associated with this approach. The method is applied to a subset of the Palomar-Green quasar sample for which independent BLR size measurements are available. An agreement is found between the results of the photometric method and the spectroscopic reverberation mapping technique. Implications for the measurement of BLR sizes and black hole masses for numerous quasars in the era of large surveys are discussed.

description: “La risoluzione di un problema, [...] è un’operazione complessa che richiede l’applicazione di parecchie conoscenze. Ne consegue che [...] occorre [...] impostare una didattica che porti l’allievo a saper affrontare un problema.” (Arigoni et al., 1992, p. 23). Questo lavoro di tesi si basa su tale affermazione, declinandola al contesto dei problemi con immagine in una classe di seconda elementare, con allievi che sperimentano per le prime volte questo genere di attività. Tramite delle attività di risoluzione, discussione e delle interviste semi-strutturate con quattro alunni selezionati, si è indagato il ruolo dell’immagine nella risoluzione di problemi e la sua influenza sul processo risolutivo. Tra gli aspetti emersi, vi è un’evoluzione nel considerare l’immagine al fine di pianificare il protocollo risolutivo e non tanto per determinare la difficoltà del problema. Tale progetto ha contribuito a sviluppare negli allievi una maggiore consapevolezza nei confronti della risoluzione di problemi, sensibilizzando alla dimensione personale della rappresentazione semiotica e abbattendo un apparente contratto didattico nei confronti dell’organizzazione della stessa.

description: Thin films composed of Ge nanocrystals embedded in amorphous SiO2 matrix (Ge-NCs TFs) were prepared using a low temperature in-situ growth method. Unexpected high p-type conductivity was observed in the intrinsic Ge-NCs TFs. Unintentional doping from shallow dopants was excluded as a candidate mechanism of hole generation. Instead, the p-type characteristic was attributed to surface state induced hole accumulation in NCs, and the hole conduction was found to be a thermally activated process involving charge hopping from one NC to its nearest neighbor. Theoretical analysis has shown that the density of surface states in Ge-NCs is sufficient to induce adequate holes for measured conductivity. The film conductivity can be improved significantly by post-growth rapid thermal annealing and this effect is explained by a simple thermodynamic model. The impact of impurities on the conduction properties was also studied. Neither compensation nor enhancement in conduction was observed in the Sb and Ga doped Ge-NCs TFs, respectively. This could be attributed to the fact that these impurities are no longer shallow dopants in NCs and are much less likely to be effectively activated. Finally, the photovoltaic effect of heterojunction diodes employing such Ge-NCs TFs was characterized in order to demonstrate its functionality in device implementation.

description: In the first part of this paper, the different distinguishable pathways and regions of the single and sequential double ionization are determined and discussed. It is shown that there are two distinguishable pathways for the single ionization and four distinct pathways for the sequential double ionization. It is also shown that there are two and three different regions of space which are related to the single and double ionization respectively. In the second part of the paper, the time dependent Schrödinger and Newton equations are solved simultaneously for the electrons and the nuclei of H$_2$ respectively. The electrons and nuclei dynamics are separated on the base of the adiabatic approximation. The soft-core potential is used to model the electrostatic interaction between the electrons and the nuclei. A variety of wavelengths (390 nm, 532 nm and 780 nm) and intensities ($5\times10^{14}$ $Wcm^{-2} $ and $ 5\times10^{15}$ $Wcm^{-2}$) of the ultrashort intense laser pulses with a sinus second order envelope function are used. The behaviour of the time dependent classical nuclear dynamics in the absence and present of the laser field are investigated and compared. In the absence of the laser field, there are three distinct sections for the nuclear dynamics on the electronic ground state energy curve. The bond hardening phenomenon does not appear in this classical nuclear dynamics simulation.

Processes and patterns of cocaine use among patients receiving injectable opioids for the treatment of opioid use disorder : a multi-method study
Creators: name: Palis, Heather Nadine
Publisher: name: University of British Columbia
Year: 2020

description: Background: Injectable opioid agonist treatment with hydromorphone (a licensed opioid analgesic) or diacetylmorphine (pharmaceutical grade heroin) is effective at reducing illicit opioid use and improving health and social functioning among patients with opioid use disorder. Concurrent cocaine use is prevalent among patients receiving injectable opioid agonist treatment, however modest declines have been observed in the proportion of patients using cocaine and in the number of days of cocaine use while engaged in treatment. To date, studies have not explored what processes might explain these reductions, or how patterns of cocaine use might vary over time at the intra- and inter-individual levels. Methods: This study was conducted with patients receiving daily injectable hydromorphone or diacetylmorphine for the treatment of opioid use disorder at a clinic in Vancouver, Canada. The qualitative analysis was guided by a grounded theory approach involving one-on-one patient interviews (n=31). Findings directed covariate selection for the quantitative analysis. The profile of participants using cocaine was characterized (n=166), and multilevel models were used to explain variation in cocaine use over 24-months, using data from a baseline visit and six follow-up visits. Results: Qualitative analysis revealed that access to injectable opioid agonist treatment promoted the self-management of cocaine use. Participants distanced themselves from the street environment, made efforts to “control” their cocaine use, and sought supports to bolster these efforts. Quantitative analyses identified significant intra- and inter-individual variation in cocaine use over 24-months. On average, cocaine use decreased over time, however the rate of change varied from one participant to the next. Women reported more cocaine use than men, and participants with more lifetime years of cocaine use at baseline reported more cocaine use over 24-months. Conclusions: This research highlights heterogeneity in patterns and processes of cocaine use. Intra- and inter-individual variation in cocaine use was identified, and was explained by participant characteristics, including demographics and substance use histories. Given daily contact with care, injectable opioid agonist treatment serves as an optimal setting to integrate treatments for cocaine use disorder. Care providers can communicate with patients about their patterns of cocaine use and associated characteristics to guide treatment plans.
Iterative Schwarz-Christoffel Transformations Driven by Random Walks and Fractal Curves

description: Stochastic Loewner evolution (SLE) is a differential equation driven by a one-dimensional Brownian motion (BM), whose solution gives a stochastic process of conformal transformation on the upper half complex-plane $\H$. As an evolutionary boundary of image of the transformation, a random curve (the SLE curve) is generated, which is starting from the origin and running in $\H$ toward the infinity as time is going. The SLE curves provides a variety of statistical ensembles of important fractal curves, if we change the diffusion constant of the driving BM. In the present paper, we consider the Schwarz-Christoffel transformation (SCT), which is a conformal map from $\H$ to the region $\H$ with a slit starting from the origin. We prepare a binomial system of SCTs, one of which generates a slit in $\H$ with an angle $απ$ from the positive direction of the real axis, and the other of which with an angle $(1-α) π$. One parameter $κ>0$ is introduced to control the value of $α$ and the length of slit. Driven by a one-dimensional random walk, which is a binomial stochastic process, a random iteration of SCTs is performed. By interpolating tips of slits by straight lines, we have a random path in $\H$, which we call an Iterative SCT (ISCT) path. It is well-known that, as the number of steps $N$ of random walk goes infinity, each path of random walk divided by $\sqrt{N}$ converges to a Brownian curve. Then we expect that the ISCT paths divided by $\sqrt{N}$ (the rescaled ISCT paths) converge to the SLE curves in $N \to \infty$. Our numerical study implies that, for sufficiently large $N$, the rescaled ISCT paths will have the same statistical properties as the SLE curves have, supporting our expectation.

description: A robótica educativa e a educação inclusiva passaram a fazer parte da realidade das escolas e integram o vocabulário dos profissionais de educação. Ensinar implica desenhar contextos propícios à aprendizagem, utilizando ferramentas didáticas com potencial pedagógico, motivacional (como é exemplo a robótica), que possam ser utilizadas nos diversos contextos educativos, promovendo uma educação para todos e cada um, em integração com os seus pares, independentemente das suas condições físicas, intelectuais, sociais, emocionais, linguísticas ou outras. Com base nestes pressupostos, o artigo relata o processo de criação de um jogo robótico, o Robot Caramelo, projeto interdisciplinar pensado numa vertente de inclusão social e curricular dos alunos de uma turma do ensino profissional que integrava alunos apoiados pela educação especial.
