description: The role of a super-Alfvénic plasmoid instability in the onset of fast reconnection is studied by means of the largest Hall magnetohydrodynamics simulations to date, with system sizes up to $10^{4}$ ion skin depths ($d_{i}$). It is demonstrated that the plasmoid instability can facilitate the onset of rapid Hall reconnection, in a regime where the onset would otherwise be inaccessible because the Sweet-Parker width is significantly above $d_{i}$. However, the topology of Hall reconnection is not inevitably a single stable X-point. There exists an intermediate regime where the single X-point topology itself exhibits instability, causing the system to alternate between a single X-point geometry and an extended current sheet with multiple X-points produced by the plasmoid instability. Through a series of simulations with various system sizes relative to $d_{i}$, it is shown that system size affects the accessibility of the intermediate regime. The larger the system size is, the easier it is to realize the intermediate regime. Although our Hall MHD model lacks many important physical effects included in fully kinetic models, the fact that a single X-point geometry is not inevitable raises the interesting possibility for the first time that Hall MHD simulations may have the potential to realize reconnection with geometrical features similar to those seen in fully kinetic simulations, namely, extended current sheets and plasmoid formation.

description: An applied theory of cylindrical bending vibrations of a bimorph plate is developed, which takes into account the nonlinear distribution of the electric potential in piezoelectric layers. Finite-element analysis of this problem showed that such distribution arises when solving the problems of finding the resonant frequencies and modes of vibration or in the case of forced oscillations during their mechanical excitation, when the electric potentials on the electrodes are zero. The quadratic distribution of the electric potential adopted in the work showed good consistency of the results with finite-element calculations for natural oscillations and steady-state oscillations for a given potential difference when the electric potential distribution is close to linear.

description: New progress in loop gravity has lead to a simple model of `general-covariant quantum field theory'. I sum up the definition of the model in self-contained form, in terms accessible to those outside the subfield. I emphasize its formulation as a generalized topological quantum field theory with an infinite number of degrees of freedom, and its relation to lattice theory. I list the indications supporting the conjecture that the model is related to general relativity and UV finite.

description: A review of three-dimensional mathematical models describing the irreversible processes of polarization of polycrystalline ferroelectrics is given. Experimental works and most frequently used models for describing hysteresis properties are considered. These include well-known phenomenological and micromechanical models. Some of them allow describing the nonlinear response under the action of electrical and mechanical loads. For each of the models, physical and mathematical features, basic formulas and calculating algorithms are presented. The main advantages and disadvantages of each of the presented models are noted. Large and small loops of dielectric and deformation hysteresis are shown. A conclusion is drawn about the unresolved problems in the field of modeling of polycrystalline ferroelectrics - ferroelastics. The list of works on the review topic is given.

description: The existence of random attractors for a large class of stochastic partial differential equations (SPDE) driven by general additive noise is established. The main results are applied to various types of SPDE, as e.g. stochastic reaction-diffusion equations, the stochastic $p$-Laplace equation and stochastic porous media equations. Besides classical Brownian motion, we also include space-time fractional Brownian Motion and space-time Lévy noise as admissible random perturbations. Moreover, cases where the attractor consists of a single point are considered and bounds for the speed of attraction are obtained.

description: We study effects of a gate-controlled Rashba spin-orbit coupling to quantum spin-Hall edge states in HgTe quantum wells. A uniform Rashba coupling can be employed in tuning the spin orientation of the edge states while preserving the time-reversal symmetry. We introduce a sample geometry where the Rashba coupling can be used in probing helicity by purely electrical means without requiring spin detection, application of magnetic materials or magnetic fields. In the considered setup a tilt of the spin orientation with respect to the normal of the sample leads to a reduction in the two-terminal conductance with current-voltage characteristics and temperature dependence typical of Luttinger liquid constrictions.

description: Using first-principles methods we performed a theoretical study of carbon clusters in silicon carbide nanowires. We examined small clusters with carbon interstitials and antisites in hydrogen-passivated SiC nanowires growth along the [100] and [111] directions. The formation energies of these clusters were calculated as a function of the carbon concentration. We verified that the energetic stability of the carbon defects in SiC nanowires depends strongly on the composition of the nanowire surface: the energetically most favorable configuration in carbon-coated [100] SiC nanowire is not expected to occur in silicon-coated [100] SiC nanowire. The binding energies of some aggregates were also obtained, and they indicate that the formation of carbon clusters in SiC nanowires is energetically favored.

description: Deep learning-based quality assessments have significantly enhanced perceptual multimedia quality assessment, however it is still in the early stages for 3D visual data such as 3D point clouds (PCs). Due to the high volume of 3D-PCs, such quantities are frequently compressed for transmission and viewing, which may affect perceived quality. Therefore, we propose no-reference quality metric of a given 3D-PC. Comparing to existing methods that mostly focus on geometry or color aspects, we propose integrating frequency magnitudes as indicator of spatial degradation patterns caused by the compression. To map the input attributes to quality score, we use a light-weight hybrid deep model; combined of Deformable Convolutional Network (DCN) and Vision Transformers (ViT). Experiments are carried out on ICIP20 [1], PointXR [2] dataset, and a new big dataset called BASICS [3]. The results show that our approach outperforms state-of-the-art NR-PCQA measures and even some FR-PCQA on PointXR. The implementation code can be found at: https://github.com/o-messai/3D-PCQA
Characterizing movement disorders and their associations with substance use and psychosis in adults living in precarious housing or homelessness
Creators: name: Kim, David
Publisher: name: University of British Columbia
Year: 2023

description: Background: Many individuals who are precariously housed or homeless live with multimorbid conditions, including substance use, psychotic, and neurological disorders. Despite high levels of susceptibility, movement disorders are understudied in these socially marginalized people. The general objective of the current dissertation was to characterize movement disorders in relation to substance use and psychosis, and also to examine their longitudinal characteristics. Methods: Participants were recruited from an impoverished neighborhood of downtown Vancouver, Canada. Data were collected on the diagnosis of psychiatric disorders, severity of signs of movement disorders and symptoms of psychosis, and recent use of drugs and substances. Cross-sectional and longitudinal mixed-effects regression analyses were used to examine the associations in question. Results: Among different types of substance use examined, methamphetamine was most consistently associated with movement disorders, including parkinsonism and dyskinesia, and the association was stronger in older female participants. Moreover, underlying psychotic disorders were associated with higher odds of clinically relevant signs of movement disorders as a result of methamphetamine and cannabis use. In turn, movement disorders were associated with impaired psychosocial functioning, greater symptoms of psychosis (negative, disorganized, and excited symptoms), and poorer cognitive functioning, especially in participants with underlying psychotic disorders. Furthermore, there were temporal relationships between movement disorders and cardinal psychotic symptoms, where preceding delusions and unusual thought content were associated with subsequent parkinsonism, and preceding dyskinesia was associated with subsequent conceptual disorganization. Lastly, parkinsonism was commonly observed in all age groups of precariously housed and homeless participants relative to the general population. The proportion affected by parkinsonism rapidly increased during the peak of the opioid epidemic, although urine fentanyl detection was not associated with parkinsonism. On the other hand, the proportion affected by dyskinesia decreased during the post-declaration period, and urine fentanyl detection was associated with lower severity of orofacial dyskinesia. Conclusions: Overall, these results suggest that movement disorders are important neurological complications in precariously housed and homeless individuals, and future studies should aim to reveal the mechanisms underlying substance use-associated movement disorders (e.g., neuroimaging markers), differentially diagnose parkinsonism (e.g., idiopathic Parkinson’s disease), and establish intervention and prevention strategies for these signs and symptoms.

description: We study the computational difficulty of computing the ground state degeneracy and the density of states for local Hamiltonians. We show that the difficulty of both problems is exactly captured by a class which we call #BQP, which is the counting version of the quantum complexity class QMA. We show that #BQP is not harder than its classical counting counterpart #P, which in turn implies that computing the ground state degeneracy or the density of states for classical Hamiltonians is just as hard as it is for quantum Hamiltonians.

Distorted mass edges at LHC from supersymmetric leptoquarks

description: Supersymmetric (SUSY) grand unified theories based on exceptional gauge groups such as E6 have recently triggered a lot of interest. Aside from top-down motivations, they contain phenomenologically interesting states with leptoquark quantum numbers. Their SUSY partners, leptoquarkinos, will appear similar to all R-odd particles in decay cascades, but mass edges in kinematic distributions- originating from the same semiexclusive final states-will however have major differences to the corresponding edges of ordinary squarks. This distortion of standard observables bears the opportunity to detect them at the LHC, but may also pose significant confusion of underlying model assumptions, which should be handled with care and, if interpreted falsely, might even prevent a possible discovery.

description: In this study, we synthesized a hydrogel from the extract of gracillaria (GR), poly-(vinyl alcohol) (PVA), glutaraldehyde (GA), and carbon nanotube (CNT). To confirm the synthesis of hydrogel, several characterizations were done, including fourier transform infra red (FTIR) and scanning electron microscope (SEM). Analysis on the material performance under various parameters (such as swelling ratio and release behavior of potassium from hydrogel into aqueous media) was also carefully evaluated based on weight measurement and flame-photometry instrumentation. FTIR spectra showed that the interaction of hydrogel components (GR, PVA, GA, CNT and Kalium-related material) involved some functional groups such as C-O, C-N, C=O, C-H sp3 as well as O-H which predominantly occurred through hydrogen bonding. The swelling ratio of technical-grade PVA-based hydrogel was higher than that of pro-analytical-grade. The hydrogel showed a typical slow release behavior for potassium ion with the release rate is 8.89 ppm for first ten minutes and the release rate average is 0.0134 ppm/minutes for the normal phase.

description: The aim of this study was to evaluate the effect of different solvents in sonication process on the formation of graphene from the electrochemical exfoliation of graphite. In short, graphite rod was exfoliated by electrochemical process with ammonium sulfate as salt-electrolyte. The exfoliated powder then sonicated under two different solvents, which are Dimethylformamide (DMF) and aqueous solution to form graphene. It was found that similar structure of graphene was obtained from both types of solvent. However, the amount of graphene produced was different due to the differences in graphene stability. Graphene is more stable in DMF solvents compared to the aqueous solution. The aqueous solution can allow the reversible reaction that can reform graphite oxide from graphene due to the existence of hydroxyl component in the aqueous solution.

description: A boundary-element scheme for analyzing initial boundary-value problems of 3-D porelasticity is considered. The scheme is based on a time-step method of numerically inverting Laplace transform. According to the method, a solution in time is calculated using quadrature formulas, based on complex values of the function in specific points. The choice of the points is determined by Lobatto method being one of Runge-Kutta methods. A possibility of using two- and three-stage Lobatto methods is considered. Using as an example the problem about a force, acting upon end of a prismatic poroelastic body, the effect of time-step on the dynamic responses of the forces is studied. The present results are compared with the results obtained on the nodes of Radau method.

description: We give a partial "quasi-stratification" of the secant varieties of the order $d$ Veronese variety $X_{m,d}$ of $\mathbb {P}^m$. It covers the set $σ_t(X_{m,d})^{\dagger}$ of all points lying on the linear span of curvilinear subschemes of $X_{m,d}$, but two "quasi-strata" may overlap. For low border rank two different "quasi-strata" are disjoint and we compute the symmetric rank of their elements. Our tool is the Hilbert schemes of curvilinear subschemes of Veronese varieties. To get a stratification we attach to each $P\in σ_t(X_{m,d})^{\dagger}$ the minimal label of a quasi-stratum containing it.

description: We discuss the mass transport of a degenerate Fermi liquid $^3$He film over a rough surface, and the film momentum relaxation time, in the framework of theoretical predictions. In the mesoscopic régime, the anomalous temperature dependence of the relaxation time is explained in terms of the interference between elastic boundary scattering and inelastic quasiparticle-quasiparticle scattering within the film. We exploit a quasiclassical treatment of quantum size effects in the film in which the surface roughness, whose power spectrum is experimentally determined, is mapped into an effective disorder potential within a film of uniform thickness. Confirmation is provided by the introduction of elastic scattering centres within the film. We model further studies on $^3$He confined in nanofluidic sample chambers with lithographically defined surface roughness. The improved understanding of surface roughness scattering may impact on enhancing the conductivity in thin metallic films.

description: Sulphonamides (SAs) are widely used in animal husbandry. In our work, based on multi-walled carbon nanotubes, a novel residue method was developed for highly sensitive and determination trace levels of sulfamethoxazole, acetyl sulfamethoxazole and aditoprim in edible swine tissues by LC-MS/MS with magnetic solid-phase extraction. The samples were extracted using 2% ammoniated acetonitrile and purified by magnetic solid phase extraction (MSPE). Under the optimal conditions, good linearity was obtained ranging from 5 to 160 μg kg−1. The limits of detection (LOD) and quantification (LOQ) were 2 μg kg−1 and 5 μg kg−1 respectively. The average recoveries were 73.9–94.8% at different spiking levels. The inter-day RSDs were 6.2–10.7% and the intra-day RSDs were 2.4–5.4%. MSPE based on multi-walled carbon nanotubes was a simple and efficient method to enrich and separate the analyses and could be successfully applied for extraction of sulfamethoxazole, acetyl sulfamethoxazole and aditoprim residues in swine tissues.

Gp78 regulation of basal mitophagy, mitochondrial health and mitochondria-endoplasmic reticulum contact sites
Creators: name: Vandevoorde, Kurt
Publisher: name: University of British Columbia
Year: 2023

description: Selective autophagic degradation of the mitochondria, or mitophagy, is a quality control mechanism through which mitochondria that are dysfunctional or no longer required are degraded. Dysregulation of mitophagy has been associated with oncogenesis and neurodegenerative diseases. Gp78 is an E3 ubiquitin ligase involved in ER-associated degradation and previously implicated in damage-induced mitophagy. Here we demonstrate that CRISPR Cas9 KO of Gp78 results in impaired basal and damage-induced mitophagy using both mtKeima and LC3-GFP-RFP assays which report on mitochondrial delivery to autolysosomes and autophagic flux, respectively. We demonstrate that impaired autophagic flux results in decreased mitochondrial potential and the accumulation of mitochondrial derived superoxide. Induction of mitochondrial fission through the overexpression of Drp1 fails to rescue decreased membrane potential in Gp78 KO cells suggesting that Gp78 regulation of mitophagy extends beyond the induction of mitochondrial fission. In our HT-1080 cell model we demonstrate that autophagosomes selectively localize to mitochondria exhibiting low membrane potential and that the regulation of membrane potential by Gp78 extends to additional cell lines other than our HT-1080 model. Mitochondria-endoplasmic reticulum (ER) contacts (MERCs) are regions of close apposition between the ER and mitochondria. These sites act as signaling hubs regulating lipid transfer, calcium signaling and mitochondrial dynamics. These structures are classified based on the type of ER (rough/smooth) associating with the mitochondria forming ribo-MERCs and smooth MERCs, respectively. Dysregulation of MERCs has been demonstrated in neurodegenerative diseases, cancer, and metabolic disorders. Here we demonstrate that COS7 and HT-1080 preferentially form smooth MERCs and rough MERCs, respectively. We have developed a novel Laplacian-based algorithm to detect MERCs in 3D super-resolution microscopy data capable of detecting endogenous and induced MERCs. We demonstrate that Gp78 and RRBP1 selectively regulate ribo-MERCs independent of one another. MERC regulation through the expression of Gp78 is dependent on GP78’s E3 ligase activity as RING-mut Gp78 failed to induce ribo-MERCs. MERCs generated through Gp78 expression exhibit convoluted tubular morphologies distinct from planar MERCs induced through artificial tether expression.

We derive the corresponding boundary conditions and construct an asymptotic representation of the solution to this initial boundary value problem when $α$ is small, by applying the theory of singular perturbation. We illustrate the effect of passivation film near and far from a grain boundary groove.

Drying and heat treatment process of bamboo strips
Creators: name: Xia, YeLing
Publisher: name: University of British Columbia
Year: 2023

description: Bamboo and its composites have been increasingly used to supplement timber-based products owing to their fast growth and superior strength attributes. To make laminated products, green bamboo strips must be dried to moisture contents below 10%. Drying determines both the productivity and quality of laminated bamboo, but is currently very inefficient due to limited understanding of many critical phenomena. This thesis investigates the fundamentals and industrial practice of bamboo strip drying, and the effects of different heat treatment processes on their morphology and properties. In the first part, green strips were subjected to different steam pretreatments called caramelization and dried in a step-wise schedule in lab. Strip deformations and flexural strength were evaluated. Mould resistance was tested using controlled inoculation experiments, and starch modification was observed by scanning electron microscopy (SEM). The results showed that the 160 °C saturated-steam caramelization reduces bamboo strength and causes longitudinal bowing, transverse deformation, and node shrinkage. The caramelization does not appear to improve mould resistance in the long term, but it delays the onset of mould colonization, which may be explained by the continued presence of modified starch. In the second part, the drying department of a typical laminated bamboo factory was investigated. Drying involves five steps in chronological order: caramelization, primary drying, ambient conditioning, steam reconditioning, and secondary drying. From monitoring in-situ environmental conditions, the step-wise drying schedule can adequately simulate the progressive tunnel kiln drying process. Statistical analysis suggests reconditioning rather than caramelization is the key process for controlling strip moisture content and dimensional changes. Bamboo cell collapse was investigated using SEM to elucidate the patterns and severity of the cellular deformation under different reconditioning regimes. Collapse occurs in parenchyma cells, and the patterns in the cross-section are complex and governed by the spatial locations relative to fiber bundles and the inner or outer edge of the culm. Bamboo requires saturated steam at higher temperatures (>100 °C) than wood for effective collapse recovery. This thesis pointed to real potential for improving industrial bamboo drying by eliminating pre-caramelization and reducing cell collapse. Further research is needed to implement the findings in bamboo industry.

description: Using Monte-Carlo simulations, we deconvolved the sliding and hopping kinetics of GFP-LacI proteins on elongated DNA from their experimentally observed seconds-long diffusion trajectories. Our simulations suggest the following results: (1) in each diffusion trajectory, a protein makes on average hundreds of alternating slides and hops with a mean sliding time of several tens of ms; (2) sliding dominates the root mean square displacement of fast diffusion trajectories, whereas hopping dominates slow ones; (3) flow and variations in salt concentration have limited effects on hopping kinetics, while in vivo DNA configuration is not expected to influence sliding kinetics; furthermore, (4) the rate of occurrence for hops longer than 200 nm agrees with experimental data for EcoRV proteins.

Effects of periodic potentials on the critical velocity of superfluid Fermi gases in the BCS-BEC crossover

description: We study the effects of an external periodic potential on the critical velocity of a superfluid Fermi gas in the crossover between the Bardeen-Cooper-Schrieffer (BCS) phase and Bose-Einstein condensation (BEC). We numerically solve the Bogoliubov-de Gennes equations to model a three-dimensional (3D) gas of ultracold atoms in the superfluid phase flowing through a 1D optical lattice. We find that when the recoil energy is comparable to the Fermi energy, the presence of the periodic potential reduces the effect of pair-breaking excitations. This behavior is a consequence of the peculiar band structure of the quasiparticle energy spectrum in the lattice. When the lattice height is much larger than the Fermi energy, the periodic potential makes pairs of atoms to be strongly bound even in the BCS regime and pair-breaking excitations are further suppressed. We have also found that when the recoil energy is comparable to or larger than the Fermi energy, the critical velocity due to long-wavelength phonon excitations shows a non-monotonic behavior along the BCS-BEC crossover.

description: Let $k$ be an algebraically closed field of characteristic $p > 0$, and let $G$ be a simple, simply connected algebraic group defined over $\mathbb{F}_p$. Given $r \geq 1$, set $q=p^r$, and let $G(\mathbb{F}_q)$ be the corresponding finite Chevalley group. In this paper we investigate the structure of the first cohomology group $H^1(G(\mathbb{F}_q),L(λ))$ where $L(λ)$ is the simple $G$-module of highest weight $λ$. Under certain very mild conditions on $p$ and $q$, we are able to completely describe the first cohomology group when $λ$ is less than or equal to a fundamental dominant weight. In particular, in the cases we consider, we show that the first cohomology group has dimension at most one. Our calculations significantly extend, and provide new proofs for, earlier results of Cline, Parshall, Scott, and Jones, who considered the special case when $λ$ is a minimal nonzero dominant weight.

Chiral unitary approach to η' N scattering at low energies

description: We study the η' N interaction within a chiral unitary approach which includes πN, ηN and related pseudoscalar meson-baryon coupled channels. Since the SU(3) singlet does not contribute to the standard interaction and the η' is mostly a singlet, the resulting scattering amplitude is very small and inconsistent with experimental estimations of the η' N scattering length. The additional consideration of vector meson-baryon states into the coupled channel scheme, via normal and anomalous couplings of pseudoscalar to vector mesons, enhances substantially the η' N amplitude. We also exploit the freedom of adding to the Lagrangian a new term, allowed by the symmetries of QCD, which couples baryons to the singlet meson of SU(3). Adjusting the unknown strength to the η' N scattering length, we obtain predictions for the elastic η' N --> η' N and inelastic η' N --> ηN, πN, KΛ, KΣ cross sections at low η' energies, and discuss their significance.
