description: Aims: Stars twinkle because their light propagates through the atmosphere. The same phenomenon is expected at a longer time scale when the light of remote stars crosses an interstellar molecular cloud, but it has never been observed at optical wavelength. In a favorable case, the light of a background star can be subject to stochastic fluctuations on the order of a few percent at a characteristic time scale of a few minutes. Our ultimate aim is to discover or exclude these scintillation effects to estimate the contribution of molecular hydrogen to the Galactic baryonic hidden mass. This feasibility study is a pathfinder toward an observational strategy to search for scintillation, probing the sensitivity of future surveys and estimating the background level. Methods: We searched for scintillation induced by molecular gas in visible dark nebulae as well as by hypothetical halo clumpuscules of cool molecular hydrogen ($\mathrm{H_2-He}$) during two nights. We took long series of 10s infrared exposures with the ESO-NTT telescope toward stellar populations located behind visible nebulae and toward the Small Magellanic Cloud (SMC). We therefore searched for stars exhibiting stochastic flux variations similar to what is expected from the scintillation effect. According to our simulations of the scintillation process, this search should allow one to detect (stochastic) transverse gradients of column density in cool Galactic molecular clouds of order of $\sim 3\times 10^{-5}\,\mathrm{g/cm^2/10\,000\,km}$. Results: We found one light-curve that is compatible with a strong scintillation effect through a turbulent structure characterized by a diffusion radius $R_{diff}<100\, km$ in the B68 nebula. Complementary observations are needed to clarify the status of this candidate, and no firm conclusion can be established from this single observation. We can also infer limits on the existence of turbulent dense cores (of number density $n>10^9\, cm^{-3}$) within the dark nebulae. Because no candidate is found toward the SMC, we are also able to establish upper limits on the contribution of gas clumpuscules to the Galactic halo mass. Conclusions: The limits set by this test do not seriously constrain the known models, but we show that the short time-scale monitoring for a few $10^6 star\times hour$ in the visible band with a $>4$ meter telescope and a fast readout camera should allow one to quantify the contribution of turbulent molecular gas to the Galactic halo. The LSST (Large Synoptic Survey Telescope) is perfectly suited for this search.

description: Two component Bose gas in a double well potential with repulsive interactions may undergo a phase separation transition if the inter-species interactions outweigh the intra-species ones. We analyze the transition in the strong interaction limit within the two-mode approximation. Numbers of particles in each potential well are equal and constant. However, at the transition point, the ground state of the system reveals huge fluctuations of numbers of particles belonging to the different gas components. That is, probability for observation of any mixture of particles in each potential well becomes uniform.

description: The overall objective of the study was to assess the levels of human impacts on nature based on the European hemeroby approach in Bangladesh. Empirical data was used in this study. Based on the respondents’ perceptions a set of parameters was developed and compiled in a matrix. Forest, vegetation, landscape and biodiversity were identified as the scale of naturalness. It was found that ahemorobic (disturbance-free) habitats are absent in Bangladesh. The natural forest remnants are highly degraded and fragmented. The probability of emerging natural successional forests is disappeared due to the massive destruction of natural regeneration. The natural landscape is degraded by unplanned urbanization and industrialization. Biodiversity is in peril due to natural habitat destruction, logging and poaching. The study advocated for a mitigation strategy to heal nature.

description: We show that topology of the low-energy band structure in bilayer graphene critically depends on mechanical deformations of the crystal which may easily develop in suspended graphene flakes. We describe the Lifshitz transition that takes place in strained bilayers upon splitting the parabollic bands at intermediate energies into several Dirac cones at the energy scale of few meV. Then, we show how this affects the electron Landau level spectra and the quantum Hall effect.

Robust reinforcement learning with intrinsic stochasticity in real-time simulation
Creators: name: Dershan, Ram
Publisher: name: University of British Columbia
Year: 2022

description: With the advent of Industry 4.0, we see a push for manufacturing processes to be more intelligent. One of the main components of a manufacturing process are the robots, which also must be intelligent and more autonomous. One method of achieving intelligent robots is the use of reinforcement learning (RL). However, the need for large data samples for learning forces us to use simulations to train RL agents for robotic tasks. While simulations help alleviate the data burden, they can negatively impact the robustness of RL agents. Since simulations are not necessarily accurate representations of the real-world, the agents trained in these environments are sensitive to modelling errors and input disturbances, resulting in failure when transferred to the real-world. Many solutions exist to improve the sim-to-real transfer of agents to make them more robust. These solutions include system identification, domain adaptation, and domain randomization. While these methods succeed in creating more robust agents, they are highly extensive, heuristic, and require expert knowledge to implement them. In this work, we propose a method based on the principles of domain randomization that produces robust agents with simpler implementation. We start by proposing a novel simulation platform that incorporates robot dynamics into an existing industrial simulation tool, CIROS, to allow high-fidelity simulations of manufacturing processes. During the testing of this platform, we notice some intrinsic stochasticity in the robot trajectories caused by its real-time nature. We investigate this intrinsic stochasticity further and find that it is comparable to the stochasticity of a real-robot. Based on this finding, we propose using the intrinsic stochasticity as a simpler alternative to domain randomization for robust RL. We validate this claim by training and evaluating the robustness of an agent trained on the intrinsic stochasticity. We found that our method produces a significant level of robustness and can indeed be a viable alternative that is easier to implement than existing solutions.
"Farming in a fishbowl"- landowners' motivations to initiate the collaborative riparian restoration
Creators: name: Rahimova, Nargiz
Publisher: name: University of British Columbia
Year: 2022

description: This study looks into landowners’ motives to initiate a collaborative riparian restoration project in the southern interior of British Columbia, Canada. The project intends to coordinate restoration activities across several adjoining parcels, better aligning activities with the natural riparian processes than would occur through individual, uncoordinated actions. This study provided a number of important insights into the understanding of factors motivating collective restoration projects. The study also helped understand the specific social-ecological context where riparian restoration can be used as an adaptation approach to climate change by farming communities. This analysis highlights that the emergence and execution of this project was the result of a coincidence of enabling conditions. Important initial triggers included impacts from changing weather patterns that increase farming costs and a threat of regulatory action. Landowners’ perception of being in a ‘fishbowl’ in relation to a nearby residential subdivision created a perceived need to act as a group and demonstrate their pro-environmental attitudes. The availability of a funding program targeted at group farm projects enabled this project to proceed. Improved knowledge about climate change and the role of ecosystems in mitigating the impacts, facilitated by the restoration practitioners, served as an important driver for change in motivations and intention to proceed despite regulatory and project management hurdles and delays. Although a supportive regulatory environment was found important to motivating the restoration collective action, institutional barriers do not discourage participation if other enabling factors are present.

Higgs as a pseudo-Goldstone boson, the mu problem and gauge-mediated supersymmetry breaking

description: We study the interplay between the spontaneous breaking of a global symmetry of the Higgs sector and gauge-mediated supersymmetry breaking, in the framework of a supersymmetric model with global SU(3) symmetry. In addition to solving the supersymmetric flavour problem and alleviating the little hierarchy problem, this scenario automatically triggers the breaking of the global symmetry and provides an elegant solution to the mu/Bmu problem of gauge mediation. We study in detail the processes of global symmetry and electroweak symmetry breaking, including the contributions of the top/stop and gauge-Higgs sectors to the one-loop effective potential of the pseudo-Goldstone Higgs boson. While the joint effect of supersymmetry and of the global symmetry allows in principle the electroweak symmetry to be broken with little fine-tuning, the simplest version of the model fails to bring the Higgs mass above the LEP bound due to a suppressed tree-level quartic coupling. To cure this problem, we consider the possibility of additional SU(3)-breaking contributions to the Higgs potential, which results in a moderate fine-tuning. The model predicts a rather low messenger scale, a small tan beta value, a light Higgs boson with Standard Model-like properties, and heavy higgsinos.

description: Using the dS/QFT correspondence in the context of inflation allows for the study of interesting, otherwise inaccessible physics. In particular, by studying inflation via its dual field theory at the boundary of the de Sitter space, it may be possible to study a regime of strongly coupled gravity at early times. The purpose of this work is to completely express cosmological observables in terms of the free parameters of a dual field theory and to compare them with CMB data. In this way, constraints on the observational parameters constrains the validity of the strongly coupled inflation picture by imposing limits on the parameters of the field theory. The fit with data defines a limit for the consistency and validity of the approach taken and shows that, within this limit, the model is almost unconstrained, but quite predictive, producing power spectra of density perturbations extremely near scale invariance.

description: I review recent approaches to constructing supersymmetric lattice theories focusing in particular on the concept of topological twisting. The latter technique is shown to expose a nilpotent, scalar supersymmetry which can be implemented exactly in the lattice theory. Using these ideas a lattice action for $\mathcal{N}=4$ super Yang-Mills in four dimensions can be written down which is gauge invariant, free of fermion doublers and respects one out of a total of 16 continuum supersymmetries. It is shown how these exact symmetries together with the large point group symmetry of the lattice strongly constrain the possible counterterms needed to renormalize the theory and hence determine how much residual fine tuning will be needed to restore all supersymmetries in the continuum limit. We report on progress to study these renormalization effects at one loop. We go on to give examples of applications of these supersymmetric lattice theories to explore the connections between gauge theories and gravity.

description: We study the electrical detection of spin accumulation at a ferromagnet-silicon interface, which can be verified by measuring a Hanle effect in three-terminal lateral devices. The device structures used consist of a semiconducting Si channel and a high-quality Schottky tunnel contact. In a low current-bias region, the Hanle-effect curves are observed only under forward bias conditions. This can be considered that the electrical detectability of the forward-biased contact is higher than that of the reverse-biased contact. This is possible evidence for the detection of spin-polarized electrons created in a Si channel.

description: We study (pre-)sheaves in bicategories on geometric categories: smooth manifolds, manifolds with a Lie group action and Lie groupoids. We present three main results: we describe equivariant descent, we generalize the plus construction to our setting and show that the plus construction yields a 2-stackification for 2-prestacks. Finally we show that, for a 2-stack, the pullback functor along a Morita-equivalence of Lie groupoids is an equivalence of bicategories. Our results have direct applications to gerbes and 2-vector bundles. For instance, they allow to construct equivariant gerbes from local data and can be used to simplify the description of the local data. We illustrate the usefulness of our results in a systematic discussion of holonomies for unoriented surfaces.

description: This work is motivated by a real work problem: objectivization. It consists in explaining the subjective drivability using physical criteria coming from signals measured during experiments. We suggest an approach for the discriminant variables selection trying to take advantage of the functional nature of the data. The porblem is ill-posed, since the number of explanatory variables is hugely greater than the sample size. The strategy proceeds in three steps: a signal preprocessing including wavelet denoising and synchronization, dimensionality reduction by compression using a common wavelet basis, and finally the selection of useful variables using a stepwise strategy involving successive applications of the CART method.

In the present work, we calculate the masses and decay constants of mesons containing either both quarks from the fourth generation or one from fourth family and the other from known third family SM quarks in the framework of the QCD sum rules. In the calculations, we take into account two gluon condensate diagrams as nonperturbative contributions. The obtained results reduce to the known masses and decay constants of the $\bar b b$ and $\bar c c$ quarkonia when the fourth family quark is replaced by the bottom or charm quark.

Fixel based analysis of relapsing remitting multiple sclerosis subjects
Creators: name: Lesack, Nikolai Ingvald
Publisher: name: University of British Columbia
Year: 2022

description: Magnetic resonance imaging (MRI) is an important tool in the diagnosis and monitoring of multiple sclerosis (MS). Diffusion MRI can be used to probe changes in normal appearing white matter (NAWM) through its ability to image changes in water diffusivity. Standard diffusion imaging techniques such as diffusion tensor imaging (DTI) are limited in their ability to quantify regions containing complex fibre geometries. The technique of fixel-based analysis (FBA) extracts information on the properties of fibre bundles within white matter and has shown advantages in analyzing areas containing complex fibre geometries. In this work, FBA and DTI analysis were applied to a set of relapsing remitting MS subjects (RRMS) and healthy controls. An image analysis pipeline was created to extract fixel-based and DTI metrics for MS lesions, NAWM adjacent lesions, and all NAWM. Comparisons were made between fixel-based and DTI metrics for differing disease modifying therapy (DMT) treatments in the three brain regions. We found significant differences in both fixel-based and DTI metrics between RRMS subjects and healthy controls. We found that the NAWM adjacent to MS lesions showed significant differences in fixel-based and DTI metrics compared to MS lesions and NAWM. Differences in fixel-based and DTI metrics between MS lesions and NAWM may indicate that fixel-based metrics can probe disease that extends out from MS lesions into NAWM. Analysis was performed to compare fixel-based and DTI metrics based on DMT. No significant trends were found between DMTs in terms of fixel-based and DTI metrics. This analysis is limited by the low sample sizes in this work. Further studies are needed to determine if small differences in fixel-based and DTI metrics can be observed between DMTs.

description: There are currently two optical interferometry recombiners that can provide spectral resolutions better than 10000, AMBER/VLTI operating in the H-K bands, and VEGA/CHARA, recently commissioned, operating in the visible. These instruments are well suited to study the wind activity of the brightest AB supergiants in our vicinity, in lines such as H$α$ or BrGamma. We present here the first observations of this kind, performed on Rigel (B8Ia) and Deneb (A2Ia). Rigel was monitored by AMBER in two campaigns, in 2006-2007 and 2009-2010, and observed in 2009 by VEGA; whereas Deneb was monitored in 2008-2009 by VEGA. The extension of the Halpha and BrGamma line forming regions were accurately measured and compared with CMFGEN models of both stars. Moreover, clear signs of activity were observed in the differential visibility and phases. These pioneer observations are still limited, but show the path for a better understanding of the spatial structure and temporal evolution of localized ejections using optical interferometry.

description: Non-small cell lung cancer (NSCLC) is one of the most prevalent cancers diagnosed worldwide, yet managing it is still challenging. The epidermal growth factor receptor (EGFR) exhibits aberrant signalling in a wide range of human cancers, and it is reported to overexpress in most NSCLC cases. The monoclonal antibody [Cetuximab (Cet)] was conjugated onto the surface of the poly (lactide-co-glycolide) (PLGA) nanoparticles which were loaded with docetaxel (DTX) for the development of targeted therapy against lung cancer. This site-specific delivery system exhibited an enhanced cellular uptake in lung cancer cells which overexpress EGFR (A549 and NCI-H23). The nanoparticles also showed better therapeutic effectiveness against NSCLC cells, as evidenced by reduced IC50 values, cell cycle arrest at the G2/M phase, and increased apoptosis. The improved efficacy and in vivo tolerance of Cet-DTX NPs were demonstrated in benzo(a)pyrene (BaP)-induced lung cancer mice model. Histopathological analysis showed that intravenous injection of Cet-DTX NP to mice carrying lung cancer greatly reduced tumour development and proliferation. Comparing Cet-DTX NP to free drug and unconjugated nanoparticles, it also had negligible side effects and improved survival rates. Therefore, Cet-DTX NPs present a promising active targeting carrier for lung tumour-NSCLC-selective treatment.

description: Assuming that the lightest neutral component in an SU(2)L gauge multiplet is the main ingredient of dark matter in the universe, we calculate the elastic scattering cross section of the dark matter with nucleon, which is an important quantity for the direct detection experiments. When the dark matter is a real scalar or a Majorana fermion which has only electroweak gauge interactions, the scattering with quarks and gluon are induced through one- and two-loop quantum processes, respectively, and both of them give rise to comparable contributions to the elastic scattering cross section. We evaluate all of the contributions at the leading order and find that there is an accidental cancellation among them. As a result, the spin-independent cross section is found to be O(10^-(46-48)) cm^2, which is far below the current experimental bounds.

description: Carnot's theorem poses a fundamental limit on the maximum efficiency achievable from an engine that works between two reservoirs at thermal equilibrium. We extend this result to the case of arbitrary nonthermal stationary reservoirs, even with quantum coherence. In order to do this we prove that a single nonthermal reservoir is formally equivalent to multiple equilibrium ones. Finally, we discuss the possibility of realizing an engine that works at unit efficiency by exploiting quantum coherence present in the reservoir.

description: La maladie de kahler ou myélome multiple est une hémopathie maligne, caractérisée par une prolifération plasmocytaire monoclonale envahissant la moelle osseuse. C’est une maladie très hétérogène dans sa présentation clinique.

Notre travail concerne une étude rétrospective, portant sur 61 patients hospitalisés durant la période du 2017 jusqu’à 2021 dans le Centre National d’Oncologie de Nouakchott, dont le diagnostic était retenu conformément aux nouveaux critères diagnostiques de l’International Myeloma Working Group.

Cette étude a pour objectif de cerner les différents aspects du myélome multiple et de les comparer aux résultats de la littérature.

Sur le plan épidémiologique, l’âge moyen de nos patients était de 59 ans (extrêmes de 40-74 ans), avec un sexe-ratio (H/F) de 1,34.

Sur le plan clinique, les signes osseux ont dominé la symptomatologie révélatrice. La douleur osseuse a été retrouvée dans (86%), les manifestations hématologiques (70%), l’altération de l’état général (42%) et les manifestations rénales (26,3%).

Sur le plan radiologique, les atteintes ostéolytiques du rachis, de la paroi thoracique, et du crâne étaient les plus fréquentes.

Sur le plan biologique, les troubles observés étaient : La présence d’un pic monoclonal chez (93%) des cas, une augmentation de la vitesse de sédimentation (86%), une anémie a été notée dans (83%), dont (47%) sous forme d’une anémie normocytaire, normochrome. Une hyperleucocytose a été observée dans (19,6%), une leucopénie chez (6,5%), et une thrombopénie dans (11,4%). Le médullogramme a été concluant dans (92%) des cas où il a mis en évidence une plasmocytose à plus de (10%).

L’immunoglobuline monoclonale était une IgG (64%), une IgA (24%), une chaine légère (12%), avec une prédominance des chaines légères kappa dans (68%).

Selon la classification pronostique de Durie et Salmon, nos patients étaient au stade III à (78,7%), et au stade II à (21,3%).

D’après le score International Staging System, nos patients étaient au stade III à (41%), stade II à (23 %), et (32,7%) des cas n’ont pas pu être classés faute de données.

Sur le plan évolutif, on constate 26 décès, et 21 perdus de vue, diminuant alors le nombre de sujets toujours suivis au 14 cas.

Le myélome multiple demeure encore une maladie incurable, malgré le progrès technique et thérapeutique.

CLT for U-statistics of Ornstein-Uhlenbeck branching particle system with small branching rate

Publisher: name: arXiv

Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: In this paper we consider a branching particle system consisting of particles moving according to the Ornstein-Uhlenbeck process in R^d and undergoing a binary, supercritical branching with a constant rate λ>0. This system is known to fulfil a law of large numbers (under exponential scaling). In the paper we prove the corresponding central limit theorem. Moreover, in the second part of the paper we consider U-statistics of the system, for which, under mild assumptions, we prove a law of large numbers and a central limit theorem. The limits are expressed in terms of multiple stochastic integrals with respect to a random Gaussian measure. The second order behaviour depends qualitatively on the growth rate of the system. In this paper we concentrate on the case when the growth rate is relatively small comparing to smoothing properties of particles' movement.

Magneto-structural coupling and harmonic lattice dynamics in CaFe$_2$As$_2$ probed by Mössbauer spectroscopy

description: In this paper we present detailed Mössbauer spectroscopy study of structural and magnetic properties of the undoped parent compound CaFe$_2$As$_2$ single crystal. By fitting the temperature dependence of the hyperfine magnetic field we show that the magneto-structural phase transition is clearly first-order in nature and we also deduced the compressibility of our sample to be $1.67\times10^{-2}\,GPa^{-1}$. Within the Landau's theory of phase transition, we further argue that the observed phase transition may stem from the strong magneto-structural coupling effect. Temperature dependence of the Lamb-Mössbauer factor show that the paramagnetic phase and the antiferromagnetic phase exhibit similar lattice dynamics in high frequency modes with very close Debye temperatures, $Θ_D \sim$270\,K.

Characterization of overdose survivors and their outcomes in opioid agonist treatment : findings from a pragmatic, pan-Canadian, randomized control trial
Creators: name: Crepeault, Hannah
Publisher: name: University of British Columbia
Year: 2022

description: Background: Canada is currently facing an overdose epidemic primarily attributed to prescription and synthetic opioids. Previous work has revealed that individuals with a history of non-fatal overdose (NFO) are at a higher risk of mortality, but little is known about treatment outcomes among this population. The aim of this thesis was to characterize opioid agonist treatment (OAT) seeking individuals with prescription-type opioid use disorder (POUD) and a history of NFO, as well as their treatment outcomes. Methods: Data were drawn from OPTIMA, a multi-site, 24-week, pragmatic, randomized control trial evaluating the relative effectiveness of buprenorphine/naloxone and methadone models of care for adults with POUD. Multivariable logistic regression was used to determine correlates of NFO and to explore treatment retention among participants with a history of NFO. Analysis of covariance (ANCOVA) was used to examine the mean difference in opioid use between treatment arms. Finally, descriptive statistics were produced to determine the prevalence of overdose during treatment and investigate patterns of opioid use before and after overdose. Results: Among the 272 randomized participants, 159 (58%) had a lifetime history of NFO. Homelessness, receiving income assistance and positive urine drug screens (UDS) for fentanyl and methamphetamine were all independently associated with a history of NFO. Among participants with a history of NFO, retention was 17% for the buprenorphine/naloxone group and 18% for the methadone group and was not statistically different between the treatment arms (p = 0.54). Across the study period, there was an 11.9% adjusted mean difference in opioid-free UDS, favouring the buprenorphine/naloxone arm (95% CI= 3.5 to 20.3; p=0.0057). A total of 24 overdoses were reported during the study period (6 participants randomized to buprenorphine/naloxone; 12 randomized to methadone). All participants that initiated treatment continued to use opioids after overdose. Conclusions: Findings from this research indicate that a considerable proportion of OAT-seeking individuals have a history of NFO. Low retention rates and high opioid use in treatment highlight the importance of an individualized, multidimensional approach to treatment for this population. Timely initiation of low-barrier treatment and interventions to address socio-structural barriers could potentially mitigate future overdose and improve treatment outcomes.
