description: 3D hand shape and pose estimation from a single depth map is a new and challenging computer vision problem with many applications. Existing methods addressing it directly regress hand meshes via 2D convolutional neural networks, which leads to artefacts due to perspective distortions in the images. To address the limitations of the existing methods, we develop HandVoxNet++, i.e., a voxel-based deep network with 3D and graph convolutions trained in a fully supervised manner. The input to our network is a 3D voxelized-depth-map-based on the truncated signed distance function (TSDF). HandVoxNet++ relies on two hand shape representations. The first one is the 3D voxelized grid of hand shape, which does not preserve the mesh topology and which is the most accurate representation. The second representation is the hand surface that preserves the mesh topology. We combine the advantages of both representations by aligning the hand surface to the voxelized hand shape either with a new neural Graph-Convolutions-based Mesh Registration (GCN-MeshReg) or classical segment-wise Non-Rigid Gravitational Approach (NRGA++) which does not rely on training data. In extensive evaluations on three public benchmarks, i.e., SynHand5M, depth-based HANDS19 challenge and HO-3D, the proposed HandVoxNet++ achieves state-of-the-art performance. In this journal extension of our previous approach presented at CVPR 2020, we gain 41.09% and 13.7% higher shape alignment accuracy on SynHand5M and HANDS19 datasets, respectively. Our method is ranked first on the HANDS19 challenge dataset (Task 1: Depth-Based 3D Hand Pose Estimation) at the moment of the submission of our results to the portal in August 2020.

description: Context: Stellar pulsations in main-sequence B-type stars are driven by the kappa-mechanism due to the Fe-group opacity bump. The current models do not predict the presence of instability strips in the B spectral domain at very low metallicities. As the metallicity of the SMC is lower than Z=0.005, it constitutes a very suitable object to test these predictions. Aims: The main objective is to investigate the existence of B-type pulsators at low metallicities, searching for short-term periodic variability in absorption-line B and Be stars in the SMC. The analysis has been performed in a sample of 313 B and Be stars with fundamental astrophysical parameters accurately determined from high-resolution spectroscopy. Methods: Photometric light curves of the MACHO project have been analyzed using standard Fourier techniques and linear and non-linear least squares fitting methods. The position of the pulsating stars in the HR diagram has been used to ascertain their nature and to map the instability regions in the SMC. Results: We have detected 9 absorption-line B stars showing short-period variability, two among them being multiperiodic. One star is most likely a beta Cephei variable and the remaining 8 are SPB stars. The SPB instability strip in the SMC is shifted towards higher temperatures than the Galaxy. In the Be star sample, 32 stars are short-period variables, 20 among them multiperiodic. 4.9% of B stars and 25.3% of Be stars are pulsating stars. Conclusions: beta Cephei and SPB stars do exist at the SMC metallicity. The fractions of SPB stars and pulsating Be stars in the SMC are lower than in the Galaxy. The fraction of pulsating Be stars in the SMC is much higher than the fraction of pulsating absorption-line B stars, as in the Galaxy.

description: We introduce a mean-field framework for the study of systems of interacting particles sharing a conserved quantity. The work generalises and unites the existing fields of asset-exchange models, often applied to socio-economic systems, and aggregation-fragmentation models, typically used in modelling the dynamics of clusters. An initial model includes only two-body collisions, which is then extended to include many-body collisions and spontaneous fragmentation. We derive self-consistency equations for the steady-state distribution, which can be solved using a population dynamics algorithm, as well as a full solution for the time evolution of the moments, corroborated with numerical simulations. The generality of the model makes it applicable to many problems and allows for the study of systems exhibiting more complex interactions that those typically considered. The work is relevant to the modelling of barchan dune fields in which interactions between the bedforms and spontaneous fragmentation due to changes in the wind are thought to lead to size-selection. Our work could also be applied in finding wealth distributions when agents can both combine assets as well as split into multiple subsidiaries.

Markovian Approximation for the Nosé--Hoover method and H-theorem

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

description: A Langevin equation with state-dependent random force is considered. When the Helmholtz free energy is a nonincreasing function of time (the H-theorem), a generalized Einstein relation is obtained. A stochastic process of the Nosé--Hoover method is discussed on the basis of the Markovian approximation. It is found that the generalized Einstein relation holds for the Fokker--Planck equation associated with the stochastic Nosé--Hoover equation. The present result indicates that the Nosé--Hoover dynamics coarse-grained with time satisfies the H-theorem and therefore works as a heat bath.

English language skills of minority language children in a French Immersion program
Creators: name: Davies, Susan
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to determine the English language skills of minority language children (experimental group) in a early total French Immersion program by comparing them with those of English-speaking children in French Immersion (English control group), and with those of minority language children in a regular English program (minority control group). Ten grade one children comprised each of the three groups of children. Listening comprehension of English was assessed using two standardized tests of English comprehension (the Peabody Picture Vocabulary Test and the Token Test for Children). English speaking skills were assessed using the Clark-Madison Test of Oral Language (a standardized test) and a ten to fifteen minute language sample. English metalinguistic skills were assessed with a phoneme deletion task used by Rosner & Simon (1971) and with two tasks used by Pratt, Tunmer & Bowey (1984): a morpheme correction task and a word order correction task. Questionnaires were used to assess attitudes towards the minority language and culture and to determine the children's home and language background. It was hypothesized that the English language skills of the experimental group would be at least as good as those of the English control group and the minority control group. The results supported the hypotheses. The experimental group did as well as the English control group on all of the measures of English comprehension and production tested. The minority control group scored lower than the English control group on all measures of English comprehension and production. They scored lower than the experimental group on the comprehension of complex commands and on the Clark-Madison Test of Oral Language. The three groups scored similarly on all of the metalinguistic tasks except on the morpheme correction task, where the minority control group scored lower than the English control group. Results support the suitability of early total French Immersion for minority language children who have their first language and culture valued and maintained.
An enquiry into criminal record holders’ lived experiences of gaining and maintaining employment.
Creators: name: Stamper, Christopher
Publisher: name: University of Leicester

Subjects: Uncategorized

description: Criminal record holders occupy one of the most marginalised positions within the labour market. There is evidence to suggest this marginalisation stems from a combination of disproportionally low levels of education and work experience, and the impact of employer discrimination. Criminal record disclosure, on the other hand, has received relatively little academic attention in relation to the labour market experience of criminal record holders. There exists a paucity of research into the impacts of criminal record disclosure, most of which is from the perspective of employers, overlooking the experiences of criminal record holders. On that basis, this thesis seeks to address this gap by giving ‘voice’ to an otherwise marginalised population. Utilising a phenomenological approach, qualitative accounts of 23 criminal record holding participants were collected. My contributions are threefold; conceptual, theoretical and methodological. First, I provide an alternative way of thinking about how disclosure creates barriers to employment. The specific act of disclosure does not need to be present to impact how criminal record holders experience the labour market – the prospect of it is enough to cause self-discipline and self-marginalisation. Second, disclosure has significant life-impacts that extend beyond the context of the labour market. The emotional, economic and social impacts of disclosure work as a cyclical process to decay feelings of hope and attachment to the labour market. Finally, I contribute a contemporary study of disclosure, conducted in the UK, that adds to a field largely dominated by overseas research. By giving ‘voice’ to criminal record holders, rather than adopting a paternalistic approach, we can begin to understand the complexity of living with disclosure. These contributions provide a legitimate basis to question the current disclosure system and how it is perceived to impact or inhibit desistance from crime.

The effect of chromatin structure on P element-induced male recombination in Drosophila melanogaster
Creators: name: Fitzpatrick, Kathleen Anne
Publisher: name: University of British Columbia
Year: 2010

description: Dysgenic male recombination (MR) induced by the P strains T-007 and OKI rarely, if ever, occurs in the heterochromatin of chromosome two. One possible explanation is that the lack of heterochromatic exchange is due to the highly condensed chromatin in this region. Butyrate (a suspected modifier of chromatin structure) induced significant levels of heterochromatic MR in dysgenic hybrids derived from crosses involving two different P strains. This finding is consistent with the hypothesis that chromatin structure can influence the insertion and excision of P elements and hence MR. Analogous experiments were performed using third chromosome suppressor of variegation (Su(var)) mutations. Neither suppressor mutation induced any heterochromatic MR, suggesting that the mode of action of these Su(var) genes is different from, and more specific than, that of butyrate. One of the mutations (325) which is thought to influence meiotic recombination frequencies, causes some alterations in euchromatic MR in crosses involving the OKI strain. The other mutation, 318, affects neither meiotic nor dysgenic recombination. Su(var) 325 is the first known "factor" to influence meiotic and dysgenic recombination similarly.

description: In a framework that makes close contact with modern effective field theories for non-relativistic bound states at zero temperature, we study the real-time evolution of a static quark-antiquark pair in a medium of gluons and light quarks at finite temperature. For temperatures ranging from values larger to smaller than the inverse distance of the quark and antiquark, 1/r, and at short distances, we derive the potential between the two static sources, and calculate their energy and thermal decay width. Two mechanisms contribute to the thermal decay width: the imaginary part of the gluon self energy induced by the Landau damping phenomenon, and the quark-antiquark color singlet to color octet thermal break up. Parametrically, the first mechanism dominates for temperatures such that the Debye mass is larger than the binding energy, while the latter, which we quantify here for the first time, dominates for temperatures such that the Debye mass is smaller than the binding energy. If the Debye mass is of the same order as 1/r, our results are in agreement with a recent calculation of the static Wilson loop at finite temperature. For temperatures smaller than 1/r, we find new contributions to the potential, both real and imaginary, which may be relevant to understand the onset of heavy quarkonium dissociation in a thermal medium.

description: The article recognizes the need to complement the existing criticism on Piranesi by Susanna Clarke with acknowledgement of the deep concern for current environmental problems evinced by that text. Employing ecocritical literary theory, it calls into question the dichotomy between fantasy literature and contemporary concerns of the primary reality. By exploring two alternative models of human relationship with the House, the secondary world entered by the characters of that portal fantasy novel, the article seeks to prove that they may serve as actual models of environmental practices and ethical stances on the relationship between man and nature. It argues that Piranesi proposes a certain form of animism as a solution to modern man’s alienation from his natural environment. Moreover, it suggests that a return to the childlike state of wonder and recognition of one’s multidimensional connection with one’s place of living is a necessary remedy for the science and greed-driven devastations of nature. The novel’s environmental ethics are interpreted in the context of Barfield’s concept of Original Participation. Using Foucault’s concept of heterotopia, the article establishes Clarke’s House as an example of heterotopia of compensation stressing the contemporary cultural silence of the Earth.

description: A mean-field like stochastic evolution equation with growth and reset terms (LGGR model) is used to model wealth distribution in modern societies. The stationary solution of the model leads to an analytical form for the density function that is successful in describing the observed data for all wealth categories. In the limit of high wealth values the proposed density function has the accepted Tsallis-Pareto shape. Our results are in agreement with the predictions of an earlier approach based on a mean-field like wealth exchange process.

description: Grazielia nummularia
(syn. Eupatorium nummularium, Dimorpholepis nummularia),
a 0.3–0.9 m tall, low-branched, white-flowered sub-shrub native to Southern Brazil (Parana´and Rio Grande do Sul), which is anatomically very similar and exhibits the same geographical distribution as G. gaudichaudieana (King and Robinson, 1987; Matzenbacher, 1979), was collected in Sapiranga (2006). The VOs in its leaves/inflorescences are also qualitatively and quantitatively very similar to those obtained from G. gaudichaudieana. Hydrocarbon monoterpenes are the main fraction (78.9%) and are composed of the same substances that make up the VOs in G. gaudichaudieana (α- pinene, 8.5%; β- pinene, 20.5%; and limonene, 36.5%). The sesquiterpene fraction is very similar to that of the G. gaudichaudieana sample obtained from Canela/05 with 10.1 vs 11.3% germacrene D. The VOs obtained from the branches of G. nummularia present some quantitative differences when compared to the plant’ s leaves: A lower percentage of pinenes (α- pinene, 2.8%; β- pinene, 10.0%) and a higher percentage of para-cymene (5.5% vs 1.8% in the leaves/inflorescences), the percentage of limonene was similar in both subsamples (31.5 vs 36.5%), and the hydrocarbon sesquiterpene germacrene D was higher in the branches (26.3% vs. 10.1%). This is the first piece of evidence showing that the lesser-known G. nummularia is not only botanically and geographically, but also chemically similar to G. gaudichaudieana, suggesting that the bouquet of volatile terpenes is likely to exert similar functions in the biological interactions of both species with insects.

description: We demonstrate that the new single crystal of YCu$_3$[OH(D)]$_{6.5}$Br$_{2.5}$ (YCOB) is a kagome Heisenberg antiferromagnet (KHA) without evident orphan spins ($\ll$ 0.8\%). The site mixing between polar OH$^-$ and non-polar Br$^-$ causes local distortions of Cu-O-Cu exchange paths, and gives rise to 70(2)\% of randomly distributed hexagons of alternate bonds ($\sim$ $J_1-ΔJ$ and $J_1+ΔJ$) and the rest of almost uniform hexagons ($\sim$ $J_1$) on the kagome lattice. Simulations of the random exchange model with $ΔJ$/$J_1$ = 0.7(1) show good agreement with the experimental observations, including the weak upturn seen in susceptibility and the slight polarization in magnetization. Despite the average antiferromagnetic coupling of $J_1$ $\sim$ 60 K, no conventional freezing is observed down to $T$ $\sim$ 0.001$J_1$, and the raw specific heat exhibits a nearly quadratic temperature dependence below 1 K $\sim$ 0.02$J_1$, phenomenologically consistent with a gapless (spin gap $\leq$ 0.025$J_1$) Dirac quantum spin liquid (QSL). Our result sheds new light on the theoretical understanding of the randomness-relevant gapless QSL behavior in YCOB, as well as in other relevant materials.

description: Let $H_d(n,p)$ signify a random $d$-uniform hypergraph with $n$ vertices in which each of the ${n}\choose{d}$ possible edges is present with probability $p=p(n)$ independently, and let $H_d(n,m)$ denote a uniformly distributed with $n$ vertices and $m$ edges. We derive local limit theorems for the joint distribution of the number of vertices and the number of edges in the largest component of $H_d(n,p)$ and $H_d(n,m)$ for the regime ${{n-1}\choose{d-1}} p,dm/n >(d-1)^{-1}+ε$. As an application, we obtain an asymptotic formula for the probability that $H_d(n,p)$ or $H_d(n,m)$ is connected. In addition, we infer a local limit theorem for the conditional distribution of the number of edges in $H_d(n,p)$ given connectivity. While most prior work on this subject relies on techniques from enumerative combinatorics, we present a new, purely probabilistic approach.

description: The maximum recoverable strain of most crystalline solids is less than 1% because plastic deformation or fracture usually occurs at a small strain. In this work, we show that a SrNi$_2$P$_2$ micropillar exhibits pseudoelasticity with a large maximum recoverable strain of ~14% under uniaxial compression via unique reversible structural transformation, double lattice collapse-expansion that is repeatable under cyclic loading. Its high yield strength (~3.8$\pm$0.5 GPa) and large maximum recoverable strain bring out the ultrahigh modulus of resilience (~146$\pm$19MJ/m$^3$) a few orders of magnitude higher than that of most engineering materials. The double lattice collapse-expansion mechanism shows stress-strain behaviors similar with that of conventional shape memory alloys, such as hysteresis and thermo-mechanical actuation, even though the structural changes involved are completely different. Our work suggests that the discovery of a new class of high performance ThCr$_2$Si$_2$-structured materials will open new research opportunities in the field of pseudoelasticity.

In particular, the motion of the wave packets is investigated and, in both the models, the classical singularity appear to be probabilistic suppressed. Moreover, the FRW wave packets approach the Planckian region in a stationary way and no evidences for a Big-Bounce, as predicted in Loop Quantum Cosmology, appear. On the other hand, the Taub wave packets provide the right behavior in predicting an isotropic Universe.

A study of biophysical phenomena associated with gas bubble trauma in fish
Creators: name: Fidler, Larry E.
Publisher: name: University of British Columbia
Year: 2010

description: The condition of Gas Bubble Trauma in fish was examined in terms of specific symptoms involving bubble development in the circulatory system and buccal cavities of fish. Based on a comparison between the conditions for bubble growth in fish exposed to supersaturated water and mammals exposed to hyperbaric and hypobaric decompression a mathematical model was developed describing environmental water threshold needed to initiate bubble growth in fish. The equation development yielded expressions which related the thresholds in total dissolved gas pressure required to initiate bubble growth in the circulatory system to the partial pressure ratio of dissolved oxygen in the environmental water, oxygen uptake ratio across the gill, the size of nucleation sites in the circulatory system, the surface tension of fish blood and environmental parameters such as water temperature, depth and barometric pressure. In the case of bubble growth in the buccal cavity, environmental water thresholds were related to total gas pressure, nuclei radius, water surface tension, water temperature, depth and barometric pressure. Bubble growth thresholds were examined for a range of the above dependent parameters.

description: We discuss an approach to the computer assisted proof of the existence of branches of stationary and periodic solutions for dissipative PDEs, using the Brussellator system with diffusion and Dirichlet boundary conditions as an example, We also consider the case where the branch of periodic solutions emanates from a branch of stationary solutions through a Hopf bifurcation.

description: We introduce a pre-symplectic structure on the space of connections in a G-principal bundle over a four-manifold and a Hamiltonian action on it of the group of gauge transformations that are trivial on the boundary. The moment map is given by the square of curvature so that the 0-level set is the space of flat connections. Thus the moduli space of flat connections is endowed with a pre-symplectic structure. In case when the four-manifold is null-cobordant we shall construct, on the moduli space of connections, as well as on that of flat connections, a hermitian line bundle with connection whose curvature is given by the pre-symplectic form. This is the Chern-Simons pre-quantum line bundle. The group of gauge transformations on the boundary of the base manifold acts on the moduli space of flat connections by an infinitesimally symplectic way. When the base manifold is a 4-dimensional disc we show that this action is lifted to the pre-quantum line bundle by its abelian extension. The geometric description of the latter is related to the 4-dimensional Wess-Zumino-Witten model. The previous version of this arxiv text had several incoincidence with the published article in the Differential Geometry and its Applications vol.29, so the author corrected them.

description: Defects which are predominant in a realistic model, usually spoil its integrability or solvability. We on the other hand show the exact integrability of a known sine-Gordon field model with a defect (DSG), at the classical as well as at the quantum level based on the Yang-Baxter equation. We find the associated classical and quantum R-matrices and the underlying q-algebraic structures, analyzing the exact lattice regularized model. We derive algorithmically all higher conserved quantities $C_n, n=1,2,...$ of this integrable DSG model, focusing explicitly on the contribution of the defect point to each $C_n$. The bridging condition across the defect, defined through the Bäcklund transformation is found to induce creation or annihilation of a soliton by the defect point or its preservation with a phase shift.

description: Suicide is the 10th leading cause of death in the U.S (1999-2019). However, predicting when someone will attempt suicide has been nearly impossible. In the modern world, many individuals suffering from mental illness seek emotional support and advice on well-known and easily-accessible social media platforms such as Reddit. While prior artificial intelligence research has demonstrated the ability to extract valuable information from social media on suicidal thoughts and behaviors, these efforts have not considered both severity and temporality of risk. The insights made possible by access to such data have enormous clinical potential - most dramatically envisioned as a trigger to employ timely and targeted interventions (i.e., voluntary and involuntary psychiatric hospitalization) to save lives. In this work, we address this knowledge gap by developing deep learning algorithms to assess suicide risk in terms of severity and temporality from Reddit data based on the Columbia Suicide Severity Rating Scale (C-SSRS). In particular, we employ two deep learning approaches: time-variant and time-invariant modeling, for user-level suicide risk assessment, and evaluate their performance against a clinician-adjudicated gold standard Reddit corpus annotated based on the C-SSRS. Our results suggest that the time-variant approach outperforms the time-invariant method in the assessment of suicide-related ideations and supportive behaviors (AUC:0.78), while the time-invariant model performed better in predicting suicide-related behaviors and suicide attempt (AUC:0.64). The proposed approach can be integrated with clinical diagnostic interviews for improving suicide risk assessments.

description: The wavelet transform modulus maxima (WTMM) used in the singularity analysis of one fractal function is extended to study the fractal correlation of two multifractal functions. The technique is developed in the framework of joint partition function analysis (JPFA) proposed by Meneveau et al. [1] and is shown to be equally effective. In addition, we show that another leading approach developed for the same purpose, namely, relative multifractal analysis, can be considered as a special case of JPFA at a particular parameter setting.

Combinatorial Hopf algebras, noncommutative Hall-Littlewood functions, and permutation tableaux

description: We introduce a new family of noncommutative analogues of the Hall-Littlewood symmetric functions. Our construction relies upon Tevlin's bases and simple q-deformations of the classical combinatorial Hopf algebras. We connect our new Hall-Littlewood functions to permutation tableaux, and also give an exact formula for the q-enumeration of permutation tableaux of a fixed shape. This gives an explicit formula for: the steady state probability of each state in the partially asymmetric exclusion process (PASEP); the polynomial enumerating permutations with a fixed set of weak excedances according to crossings; the polynomial enumerating permutations with a fixed set of descent bottoms according to occurrences of the generalized pattern 2-31.

description: Supermassive black holes launch highly relativistic jets with velocities reaching Lorentz factors as high as $Γ>50$. How the jets accelerate to such high velocities and where along the jet do they reach terminal velocity are open questions that are tightly linked to their structure, launching and dissipation mechanisms. Changes in the beaming factor along the jets could potentially reveal jet acceleration, deceleration, or bending. We aim to (1) quantify the relativistic effects in multiple radio frequencies and (2) study possible jet velocity--viewing angle variations at parsec scales. We used the state-of-the-art code Magnetron to model light curves from the University of Michigan Radio Observatory and the Metsähovi Radio Observatory's monitoring programs in five frequencies covering about 25 years of observations in the 4.8-37~GHz range for 61 sources. We supplement our data set with high-frequency radio observations in the 100-340~GHz range from ALMA, CARMA, and SMA. For each frequency we estimate the Doppler factor which we use to quantify possible changes in the relativistic effects along the jets. The majority of our sources do not show any statistically significant difference in their Doppler factor across frequencies. This is consistent with constant velocity in a conical jet, as expected at parsec scales. However, our analysis reveals 17 sources where relativistic beaming changes as a function of frequency. In the majority of cases the Doppler factor increases towards lower frequencies. Only 1253-053 shows the opposite behavior. By exploring their jet properties we find that the jet of 0420-014 is likely bent across the 4.8-340~GHz range. For 0212+735 the jet is likely parabolic, and still accelerating in the 4.8-37~GHz range. We discuss possible interpretations for the trends found in the remaining sources.

description: Cette étude analyse principalement l’effet de la croissance économique sur les inégalités de revenus dans l’espace UEMOA au cours de la période 2005-2019.

La vérification empirique du modèle économétrique par la méthode des Moindres Carrés Généralisés (MCG) sur les données de panel montre que la croissance économique réduit les inégalités de revenus dans les pays de l’UEMOA.

Par ailleurs, les résultats montrent que la hausse d’emplois agricoles contribue à réduire les inégalités de revenus dans l’union. De même une amélioration de la qualité des institutions est sources d’atténuation des inégalités de revenu dans l’espace UEMOA. Par contre, la croissance démographique contribue à creuser les inégalités de revenus, toutes choses égales par ailleurs.

description: Music is a fundamental human construct, and harmony provides the building blocks of musical language. Using the Kunstderfuge corpus of classical music, we analyze the historical evolution of the richness of harmonic vocabulary of 76 classical composers, covering almost 6 centuries. Such corpus comprises about 9500 pieces, resulting in more than 5 million tokens of music codewords. The fulfilment of Heaps' law for the relation between the size of the harmonic vocabulary of a composer (in codeword types) and the total length of his works (in codeword tokens), with an exponent around 0.35, allows us to define a relative measure of vocabulary richness that has a transparent interpretation. When coupled with the considered corpus, this measure allows us to quantify harmony richness across centuries, unveiling a clear increasing linear trend. In this way, we are able to rank the composers in terms of richness of vocabulary, in the same way as for other related metrics, such as entropy. We find that the latter is particularly highly correlated with our measure of richness. Our approach is not specific for music and can be applied to other systems built by tokens of different types, as for instance natural language.
