description: The small binding energy of the hypertrition leads to predictions of non-existence of bound hypernuclei for isotriplet three-body systems such as $nnΛ$. However, invariant mass spectroscopy at GSI has reported events that may be interpreted as the bound $nnΛ$ state. The $nnΛ$ state was sought by missing-mass spectroscopy via the $(e,e'K^+)$ reaction at Jefferson Lab's experimental Hall A. The present experiment has higher sensitivity to the $nnΛ$-state investigation in terms of better precision by a factor of about three. The analysis shown in this article focuses on the derivation of the reaction cross-section for the $^3{\rm{H}}(γ^{*},K^+)\textrm{X}$ reaction. Events that were detected in an acceptance, where a Monte Carlo simulation could reproduce the data well ($|δp/p| < 4\%$), were analyzed to minimize the systematic uncertainty. No significant structures were observed with the acceptance cuts, and the upper limits of the production cross-section of the $nnΛ$ state were obtained to be $21$ and $31~\rm{nb/sr}$ at the $90\%$ confidence level when theoretical predictions of $(-B_Λ, Γ) = (0.25,0.8)$ and $(0.55, 4.7)$ MeV, respectively, were assumed. The cross-section result provides valuable information for examining the existence of $nnΛ$.

The contemporary northwest coast Indian art market
Creators: name: Duffek, Karen Erica
Publisher: name: University of British Columbia
Year: 2010

description: In the 1960's a revival of Northwest Coast Indian art began to take place in British Columbia, following several decades of decline in art production that resulted from effects of European contact on traditional native social structure. By the late 1970's the Indian art market had become a several million dollar industry, involving several hundred native artists, and supported by a primarily non-Indian consumer public. This thesis examines the contemporary Northwest Coast Indian art market in terms of the role and significance of the art within its contemporary social context, focusing on the relationship between the consumers and the art they collect. The history of the Indian art revival, the development of the market, changes that Northwest Coast art has undergone in response to its new purpose for production, and consumer expectations and buying preferences are discussed. This thesis shows that the revival of Northwest Coast art has involved not only the artists who create the contemporary work, but also the consumers, anthropologists, museums, and dealers, who have participated with the artists in a reconstruction and redefinition of "Indianness" and tradition, and in the development of an audience to support art production. Surveys of consumers and museum visitors conducted for the thesis suggest that an important and valued quality of contemporary Northwest Coast art is its "otherness" or Indianness. Today, Northwest Coast art traditions are used in a contemporary expression that refers to the value of tradition and heritage not only to the consumers, but to native society as well. The concept of acculturated arts is used in this study of Northwest Coast Indian art, providing a comparative context of changing art forms brought about by culture contact, and illustrating the transformation of traditional cultural elements into marketable commodities for non-native tourists and collectors. This thesis is a contribution to the literature on Northwest Coast Indian art in particular, and acculturated arts in general.
Frequency dependence of induced spin polarization and spin current in quantum wells

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: Dynamic response of two-dimensional electron systems with spin-orbit interaction is studied theoretically on the basis of quantum kinetic equation, taking into account elastic scattering of electrons. The spin polarization and spin current induced by the applied electric field are calculated for the whole class of electron systems described by p-linear spin-orbit Hamiltonians. The absence of nonequilibrium intrinsic static spin currents is confirmed for these systems with arbitrary (nonparabolic) electron energy spectrum. Relations between the spin polarization, spin current, and electric current are established. The general results are applied to the quantum wells grown in [001] and [110] crystallographic directions, with both Rashba and Dresselhaus types of spin-orbit coupling. It is shown that the existence of the fixed (momentum-independent) precession axes in [001]-grown wells with equal Rashba and Dresselhaus spin velocities or in symmetric [110]-grown wells leads to vanishing spin polarizability at arbitrary frequency of the applied electric field. This property is explained by the absence of Dyakonov-Perel-Kachorovskii spin relaxation for the spins polarized along these precession axes. As a result, a considerable frequency dispersion of spin polarization at very low frequency in the vicinity of the fixed precession axes is predicted. Possible effects of extrinsic spin-orbit coupling on the obtained results are discussed.

description: As the proportion of road accidents increases each year, driver distraction continues to be an important risk component in road traffic injuries and deaths. The distractions caused by the increasing use of mobile phones and other wireless devices pose a potential risk to road safety. Our current study aims to aid the already existing techniques in driver posture recognition by improving the performance in the driver distraction classification problem. We present an approach using a genetic algorithm-based ensemble of six independent deep neural architectures, namely, AlexNet, VGG-16, EfficientNet B0, Vanilla CNN, Modified DenseNet, and InceptionV3 + BiLSTM. We test it on two comprehensive datasets, the AUC Distracted Driver Dataset, on which our technique achieves an accuracy of 96.37%, surpassing the previously obtained 95.98%, and on the State Farm Driver Distraction Dataset, on which we attain an accuracy of 99.75%. The 6-Model Ensemble gave an inference time of 0.024 seconds as measured on our machine with Ubuntu 20.04(64-bit) and GPU as GeForce GTX 1080.

description: We classify all integrable 3-dimensional scalar discrete quasilinear equations Q=0 on an elementary cubic cell of the 3-dimensional lattice. An equation Q=0 is called integrable if it may be consistently imposed on all 3-dimensional elementary faces of the 4-dimensional lattice. Under the natural requirement of invariance of the equation under the action of the complete group of symmetries of the cube we prove that the only nontrivial (non-linearizable) integrable equation from this class is the well-known dBKP-system.

description: We study the stellar binary black holes (BBHs) inspiralling/merging in galactic nuclei based on our numerical method GNC. We find that $3-40\%$ of all new born BBHs will finally merge due to various dynamical effects. In a five year's mission, up to $10^4$, $10^5$, $\sim100$ of BBHs inspiralling/merging in galactic nuclei can be detected with SNR$>8$ in aLIGO, Einstein/DECIGO, TianQin/LISA/TaiJi, respectively. About tens are detectable in both LISA/TaiJi/TianQin and aLIGO. These BBHs have two unique characteristics: (1) Significant eccentricities. $1-3\%$, $2-7\%$, or $30-90\%$ of them is with $e_i>0.1$ when they enter into aLIGO, Einstein, or space observatories, respectively. Such high eccentricities provide a possible explanation for that of GW 190521. Most highly-eccentric BBHs are not detectable in LISA/Tianqin/TaiJi before entering into aLIGO/Einstein as their strain become significant only at $f_{\rm GW}\gtrsim0.1$ Hz. DECIGO become an ideal observatory to detect those events as it can fully cover the rising phase. (2) Up to $2\%$ of BBHs can inspiral/merge at distances $\lesssim10^3 r_{\rm SW}$ from the massive black hole (MBH), with significant accelerations, such that the Doppler phase drift of $\sim10-10^5$ of them can be detectable with SNR$>8$ in space observatories. The energy density of the gravitational wave backgrounds (GWB) contributed by these BBHs deviate from the powerlaw slope of $2/3$ at $f_{\rm GW}\lesssim 1$mHz. The high eccentricity, significant accelerations and different profile of GWB of these sources make them distinguishable, thus interesting for future GW detections and tests of relativities.

Coupled-channel approach to $T_{cc}^+$ including three-body effects

description: A coupled-channel approach is applied to the charged tetraquark state $T_{cc}^+$ recently discovered by the LHCb Collaboration. The parameters of the interaction are fixed by a fit to the observed line shape in the three-body $D^0D^0π^+$ channel. Special attention is paid to the three-body dynamics in the $T_{cc}^+$ due to the finite life time of the $D^*$. An approach to the $T_{cc}^+$ is argued to be self-consistent only if both manifestations of the three-body dynamics, the pion exchange between the $D$ and $D^*$ mesons and the finite $D^*$ width, are taken into account simultaneously to ensure that three-body unitarity is preserved. This is especially important to precisely extract the pole position in the complex energy plane whose imaginary part is very sensitive to the details of the coupled-channel scheme employed. The $D^0D^0$ and $D^0D^+$ invariant mass distributions, predicted based on this analysis, are in good agreement with the LHCb data. The low-energy expansion of the $D^*D$ scattering amplitude is performed and the low-energy constants (the scattering length and effective range) are extracted. The compositeness parameter of the $T_{cc}^+$ is found to be close to unity, which implies that the $T_{cc}^+$ is a hadronic molecule generated by the interactions in the $D^{*+}D^0$ and $D^{*0}D^+$ channels. Employing heavy-quark spin symmetry, an isoscalar $D^*D^*$ molecular partner of the $T_{cc}^+$ with $J^P=1^+$ is predicted under the assumption that the $ DD^*$-$D^*D^*$ coupled-channel effects can be neglected.

description: The notions of entanglement witnesses, separable and entangled states for two qubits system can be visualized in three dimensions using the SLOCC equivalence classes. This visualization preserves the duality relations between the various sets and allows us to give ``proof by inspection'' of a non-elementary result of the Horodeckies that for two qubits, Peres separability test is iff. We then show that the CHSH Bell inequalities can be visualized as circles and cylinders in the same diagram. This allows us to give a geometric proof of yet another result of the Horodeckies, which optimizes the violation of the CHSH Bell inequality. Finally, we give numerical evidence that, remarkably, allowing Alice and Bob to use three rather than two measurements each, does not help them to distinguish any new entangled SLOCC equivalence class beyond the CHSH class.

description: Strong and weak simulation relations have been proposed for Markov chains, while strong simulation and strong probabilistic simulation relations have been proposed for probabilistic automata. However, decision algorithms for strong and weak simulation over Markov chains, and for strong simulation over probabilistic automata are not efficient, which makes it as yet unclear whether they can be used as effectively as their non-probabilistic counterparts. This paper presents drastically improved algorithms to decide whether some (discrete- or continuous-time) Markov chain strongly or weakly simulates another, or whether a probabilistic automaton strongly simulates another. The key innovation is the use of parametric maximum flow techniques to amortize computations. We also present a novel algorithm for deciding strong probabilistic simulation preorders on probabilistic automata, which has polynomial complexity via a reduction to an LP problem. When extending the algorithms for probabilistic automata to their continuous-time counterpart, we retain the same complexity for both strong and strong probabilistic simulations.

description: The transitions between neighbouring plateaux in the quantum Hall system are observed to follow anti-holomophic scaling with superuniversal scaling exponents, showing that the system contains an emergent sub-modular discrete symmetry and a holomorphic structure at low energies. We identify a class of effective scaling models consistent with this data, which is parametrized by the complex structure of a torus with a special spin structure, in which only the number of fermions (c) remains undetermined. For c = 2 this gives the superuniversal anti-holomorphic scaling potential previously inferred from data, with scaling exponent nu = 2.6, in reasonable agreement with available scaling data.

description: We study competition among contests in a general model that allows for an arbitrary and heterogeneous space of contest design, where the goal of the contest designers is to maximize the contestants' sum of efforts. Our main result shows that optimal contests in the monopolistic setting (i.e., those that maximize the sum of efforts in a model with a single contest) form an equilibrium in the model with competition among contests. Under a very natural assumption these contests are in fact dominant, and the equilibria that they form are unique. Moreover, equilibria with the optimal contests are Pareto-optimal even in cases where other equilibria emerge. In many natural cases, they also maximize the social welfare.
title: The prevalence of comorbid obsessive-compulsive disorder in individuals with eating disorders: an epidemiological meta-analysis
Creators: name: Drakes, Dalainey H.
Publisher: name: Memorial University of Newfoundland
Year: 2021

description: The present study aimed to provide a meta-analytic estimate of the prevalence of obsessive-compulsive disorder (OCD) amongst those with a current primary eating disorder (ED) diagnosis, and to isolate predictors of comorbid OCD. An online search of PubMed and PsycINFO was conducted with a Boolean search phrase incorporating keywords related to OCD, EDs, comorbidity, prevalence, and epidemiology, complemented by reference review and contact with experts in the field. Articles were included if they (a) reported an observational study examining current ED diagnoses, (b) used a semi-structured or structured diagnostic interview for OCD and ED diagnosis, (c) applied DSM or ICD criteria, (d) included adolescent or adult samples (age > 12), (e) included patient or community samples, and (f) reported lifetime or current OCD comorbidity. From the 846 articles identified, 35 lifetime and 42 current estimates of comorbid OCD were calculated. Analyses revealed an aggregate lifetime OCD prevalence of 13.9% CI₉₅% [10.4 to 18.1] and current OCD prevalence of 8.7% CI₉₅% [5.8 to 11.8] across EDs. Moderator analyses revealed the prevalence of OCD to be greatest in anorexia nervosa binge-eating purging type, in patient versus community samples, among those with an earlier age of ED onset, and those with lower mean BMIs. Awareness of the populations at greatest risk of comorbid OCD in EDs will ensure appropriate diagnosis, while facilitating development of treatments targeting their shared etiology.

description: Spin current of two-dimensional holes occupying the ground-state subband in an asymmetric quantum well and interacting with static disorder potential is calculated in the presence of a weak magnetic field H perpendicular to the well plane. Both spin-orbit coupling and Zeeman coupling are taken into account. It is shown that the applied electric field excites both the transverse (spin-Hall) and diagonal spin currents, the latter changes its sign at a finite H and becomes greater than the spin-Hall current as H increases. The effective spin-Hall conductivity introduced to describe the spin response in Hall bars is considerably enhanced by the magnetic field in the case of weak disorder and demonstrates a non-monotonic dependence on H.

description: Les polymères renforcés de fibres (PRF) à base de fibres de carbone ou de verre sont des solutions efficaces pour la réparation des ouvrages de génie civil. Afin d'apporter une solution plus responsable sur le plan environnemental, nous étudions la durabilité et la fiabilité de PRF à base de fibres de lin (PRF-L). Une campagne d'essais de dégradation accélérée à deux facteurs, température et humidité, sur une période de trois ans a été menée. Des modèles de dégradation des caractéristiques en traction, cisaillement et arrachement considérant la compétition de deux mécanismes physiques sont développés.

description: This work proposes an autonomous docking control for nonholonomic constrained mobile robots and applies it to an intelligent mobility device or wheelchair for assisting the user in approaching resting furniture such as a chair or a bed. We defined a virtual landmark inferred from the target docking destination. Then, we solve the problem of keeping the targeted volume inside the field of view (FOV) of a tracking camera and docking to the virtual landmark through a novel definition that enables to control for the desired end-pose. In this article, we proposed a nonlinear feedback controller to perform the docking with the depth camera's FOV as a constraint. Then, a numerical method is proposed to find the feasible space of initial states where convergence could be guaranteed. Finally, the entire system was embedded for real-time operation on a standing wheelchair with the virtual landmark estimation by 3D object tracking with an RGB-D camera and we validated the effectiveness in simulation and experimental evaluations. The results show the guaranteed convergence for the feasible space depending on the virtual landmark location. In the implementation, the robot converges to the virtual landmark while respecting the FOV constraints.

description: We determine in a nonperturbative way the critical velocity for superfluidity of a generic quantum fluid flowing past a localized obstacle in the one-dimensional mean-field regime. We get exact expressions in the narrow- and wide-obstacle limits and interpolate them numerically using an original relaxation algorithm for the stationary problem. The existence of a Josephson-type critical current across a very high and slowly varying obstacle is discussed. Particle losses, if present, are treated within an adiabatic approach of the dynamics giving results in excellent agreement with full numerics. Relevant for experiments with quantum fluids of matter, of mixed matter-light, and of light, our study paves the way for further nonperturbative investigations in higher dimensions and beyond mean-field theory.

description: La corrosion des armatures en acier dans les structures en béton est une cause majeure de leur détérioration. En particulier, la pénétration des ions chlorure est une problématique majeure pour la durabilité des ouvrages en béton situés en bord de mer car elle peut entrainer un développement de corrosion par piqûre. Le cas d'un quai en béton armé soumis à l’action des chlorures marins est détaillé dans cette étude. Un modèle d'élément fini spécifique (FEM) a été développé dans le but d'estimer le temps de dépassivation des armatures. Ainsi, l'étude vise à estimer la probabilité d'initiation de la corrosion lorsque la quantité de chlorure à la surface de l'armature dépasse une valeur seuil. La détermination du temps correspondant à ce dépassement, avec une probabilité prédéfinie, est une étape importante pour la maintenance d’un ouvrage. Les propriétés du béton, l'environnement externe (pression partielle de CO2, teneur en chlorures, humidité relative) sont considérés comme des variables aléatoires dans l'étude. Afin de surmonter la charge numérique du modèle dans les calculs probabilistes, un modèle de substitution basé sur un chaos polynomial est utilisé. Une analyse de sensibilité de Sobol est effectuée sur les paramètres pour observer leur influence sur le résultat.

description: Corrosion defects are a major concern for pipeline operators, and in-line inspections (ILI) are essential to detect and identify such defects and to optimize maintenance actions to avoid costly losses. However, it is crucial to conduct statistical analysis to estimate and monitor the corrosion evolution over time and enhance the accuracy of pipeline reliability assessments. This paper presents a statistical study of corrosion defect parameters (length and depth) obtained from ILI. The study evaluates statistical moments, considers the Pearson correlation coefficient, and determines the probability of failure using the Monte Carlo method based on the burst criterion. Moreover, we examine the influence of the coefficient of variation of corrosion defects on the probability of bursting by analyzing the sensitivity of key design parameters, such as operating pressure and the depth-to-wall thickness ratio. The paper employs a real case study of a corroded gas pipeline in Algeria to illustrate these findings. The results of this study can provide crucial information to pipeline operators to make informed decisions regarding maintenance activities throughout the pipeline's operational life.

description: We present results of transmission measurements on CdTe quantum wells with thin semimagnetic CdMnTe probe layers embedded in various positions along the growth axis. The presence of the probes allow us to map the probability density functions by two independent methods: analyzing the exciton energy position and the exciton Zeeman splitting. We apply both approaches to map the first three quantum well eigenstates and we find that both of them yield equally accurate results.

description: Reliability-Based Design Optimization (RBDO) is a widely used approach for optimizing engineering structures, but it often neglects the effects of fatigue. In this article, we propose an RBDO methodology that combines the Reliability Index Approach (RIA) with Dirlik spectral method for fatigue damage assessment. The RIA approach is utilized to estimate the reliability index (RI) of the structure, while Dirlik fatigue approach is employed to assess the fatigue damage. Fatigue damage is introduced as a hard constraint in the optimization process. A case study is presented to demonstrate the effectiveness of the proposed methodology. The results show that the RBDO approach, incorporating fatigue phenomenon using RIA and Dirlik spectral method, can lead to reliable and fatigue-informed optimal designs for enhanced performance and durability of cantilever beam structures. Further research can explore the applicability of the proposed methodology to other types of structures and loading conditions.

description: In this paper, we extend the notion of (word) derivatives and partial derivatives due to (respectively) Brzozowski and Antimirov to tree derivatives using already known inductive formulae of quotients. We define a new family of extended regular tree expressions (using negation or intersection operators), and we show how to compute a Brzozowski-like inductive tree automaton; the fixed point of this construction, when it exists, is the derivative tree automaton. Such a deterministic tree automaton can be used to solve the membership test efficiently: the whole structure is not necessarily computed, and the derivative computations can be performed in parallel. We also show how to solve the membership test using our (Bottom-Up) partial derivatives, without computing an automaton.

description: This work present an original uncertainty propagation method, called sprase-PCE, developed to assess the reliability of a cracked plate with spatially varying uncertain mechanical properties. It combines regression techniques to compute the unknown coefficients of the PCE-based metamodel and an efficient truncation scheme which uses prior available second order statistical moment information to identify the most important components of the polynomial chaos basis on the model responses of interest. In this way, the PCE coefficients corresponding to the components with weak effects are discarded, and the computational efforts devoted to solving the regression problem is significantly reduced. An economy index is introduced in the form of a ratio between the respective cardinalities of the sparse and the full chaos polynomial basis, which allows us to objectively assess the computational cost saving obtained by the proposed truncation scheme based on second moment information.

description: We introduce a one-dimensional (1D) XZ model with alternating $σ_i^zσ_{i+1}^z$ and $σ_i^xσ_{i+1}^x$ interactions on even/odd bonds, interpolating between the Ising model and the quantum compass model. We present two ways of its exact solution by: ($i$) mapping to the quantum Ising models, and ($ii$) using fermions with spin 1/2. In certain cases the nearest neighbor pseudospin correlations change discontinuously at the quantum phase transition, where one finds highly degenerate ground state of the 1D compass model.

description: 4. Ilyocryptus isanensis Kotov, Stifter et Sanoamuang, 2005
Localities and specimens found: 101 − 1♀.
Distribution and ecology. This is a rare species discovered in Thailand (Kotov et al. 2005; Kotov & Štifter 2006), probably endemic to Southeast Asia. At present, it is known only from Thailand and Vietnam (Kotov & Štifter 2006; Maiphae et al. 2008; Jeong et al. 2012; Korovchinsky 2013; Choedchim & Maiphae 2023; Kotov et al. 2024).
The lifestyle and ecology of this species are unstudied. Like other ilyocryptids (Kotov 2006; Kotov & Štifter 2006), it is obviously a typical bottom dweller. In Thailand, I. isanensis was recorded in a temporary pond and a rice field (Kotov et al. 2005; Choedchim & Maiphae 2023). The only female from our material was found in the Mekong Delta, in the channel zone of the Co Chien Branch (see Appendix 1).

Inhibitory effect of Browning reaction products and phenolic compounds on carcinogen-induced mutagenesis
Creators: name: Chan, Robin Isaac Man-Hang
Publisher: name: University of British Columbia
Year: 2010

description: Chemical carcinogens are highly reactive electrophilic substances capable of interacting with nucleophilic sites indiscriminately. The use of nucleophilic trapping agents that react with electrophiles could thus provide possible protection for critical cellular targets against the action of chemical carcinogens. It was on the basis of this general concept that substances in the present study were examined for possible inhibitory activities against carcinogen-induced mutagenesis. Non-enzymatic browning reactions occur in virutually all heated food stuffs. Phenolic compounds are also widely distributed in plants and are consequently present in many foods. Antimutagenic activity of two non-enzymatic browning reaction products (caramelized sucrose and lysine-fructose Maillard reaction products) and several phenolic compounds were determined in the present study. At non-toxic concentrations, the two browning reaction products and three phenolic compounds (gallic acid, caffeic acid and chlorogenic acid) significantly suppressed the mutagenicity of the carcinogen N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) in Salmonella typhimum-um strain TA 1535 and Sacchavomyces cerevis-iae strain XV185-14C. Interaction between phenolic compounds and MNNG was also studied in a cell-free system. The amount of MNNG, detected by a colorimetric method, following its incubation with phenolic compounds decreased substantially compared to that in the untreated MNNG controls. The results are consistent with the assumption that phenolic compounds scavenged reactive electrophilic MNNG degradation products thereby preventing their action on critical cellular targets. The two browning reaction products and seven phenolic compounds (tannic acid, gallic acid, caffeic acid, chlorogenic acid, salicylic acid, p-hydroxybenzoic acid and dopamine) also reduced the mutagenicity of the precarcinogen, aflatoxin B₁ (AFB₁), when assayed on Salmonella typh-imurium strain TA 98 in the presence of a rat liver microsomal activation system. The effect of phenolic compounds on the activation of AFB^ by rat liver microsomes was also studied by high-pressure liquid chromatography (HPLC). The results from the HPLC analysis suggested that one mechanism whereby the phenolic, compounds suppressed the mutagenic activity of AFB₁ is by interfering with its metabolic activation. However, the possibility remains that part of the antimutagenic activity observed may be due to interactions between the phenolic compounds and the reactive metabolite(s) of AFB₁. The present study does not permit an assessment of the relative contribution of the two mechanisms of antimutagenic action.
