description: The chiral WZNW symplectic form $Ω^ρ_{chir}$ is inverted in the general case. Thereby a precise relationship between the arbitrary monodromy dependent 2-form appearing in $Ω^ρ_{chir}$ and the exchange r-matrix that governs the Poisson brackets of the group valued chiral fields is established. The exchange r-matrices are shown to satisfy a new dynamical generalization of the classical modified Yang-Baxter (YB) equation and Poisson-Lie (PL) groupoids are constructed that encode this equation analogously as PL groups encode the classical YB equation. For an arbitrary simple Lie group G, exchange r-matrices are found that are in one-to-one correspondence with the possible PL structures on G and admit them as PL symmetries.

description: We study N=1 globally supersymmetric theories on runaway backgrounds arising from scalar potentials with a slope characterized by a scale $M = |V/V'|$. We find that, under mild assumptions, there always exists a massive goldstino in the low energy effective theory. In the simplest models the effective mass of such a fermion is of order $\sqrt{V} / M$, or of order $V / M^2 μ$ when a seesaw mechanism takes place, where $μ$ is a scale that characterizes the masses of other heavy fermions.

Creating a sustainable cover for a sand tailings dam using biosolids and log yard debris
Creators: name: Smyth, Greg
Publisher: name: The University of British Columbia
Year: 2009

description: A reclamation approach of utilizing two different types of biosolids from the GVRD and log-yard debris from the Weyerhaeuser lumber mill was tested on the sand tailings impoundment of the Smelter Lake Tailings Storage Facility at the Similco Mine, located near Princeton, BC. The purpose of this research study was targeted at creating a sustainable cover by incorporating these two products together with the top layer of the sand on the impoundment. Four test plots, each approximately 0.25 Ha in size, were created with different mixtures of log-yard debris, dewatered biosolids and land-dried biosolids. Parameters such as moisture content at 15cm and 30cm depth, physical and chemical characterization of the growth medium, vegetative yield, vegetative metal uptake and metal bioavailability of the growth medium were evaluated in an attempt to determine the effectiveness of any particular plot, or some other combination, for the reclamation of the sand impoundment. The principles of sustainable development were integral to this research project, in an effort to reclaim an old tailings facility in the most effect manner.

description: Neurodegenerative diseases are highly multifaceted. Despite their heavy burden, treatment options are limited and our understanding of their molecular triggers even less so. In this thesis, I focus on the pathogenesis of Alzheimer’s Disease (AD) due to familial, sporadic and environmental causes. Previous research shows that early AD stages are characterized by upregulated functionality of mitochondria-associated endoplasmic reticulum (ER) membranes. These “MAM” domains of the ER are dynamic contacts between the ER and mitochondria distinguished by a unique lipid composition equivalent to a lipid raft. These sites cluster a specific set of metabolic enzymes that regulate cellular lipid uptake, trafficking and turnover. We find that cleavage of the amyloid precursor protein at MAM domains is intimately involved in MAM regulation through localization of its C-terminal fragment of 99 a.a., C99, to MAM regions. C99 upregulates MAM functionality by promoting cholesterol uptake and trafficking to the ER for esterification, observable in both familial and sporadic AD samples. Here, we recapitulated these phenotypes in a mouse model of an environmental AD trigger: traumatic brain injury (TBI). Through biochemical, transcriptional and lipidomic analyses, we observed MAM functionality to be upregulated following a single brain injury. This was determined by assessment of phospholipid synthesis and cholesterol esterification. This correlated with increased deposition of C99 in MAM domains as well as cell type-specific lipidomic alterations. Specifically, cholesterol esterification was predominant in microglia, triglyceride elevations were predominant in microglia and astrocytes, and polyunsaturated phospholipid elevations were predominant in neurons. We hypothesize that, in the acute phase, MAM upregulation serves to promote lipid synthesis for tissue repair. However, if these phenotypes are sustained (such as after multiple injuries), cognitive functions dependent on neuronal functionality could become compromised. Altogether, we propose that the induction of AD pathogenesis following brain injury may arise from chronic upregulation of MAM activities. This work advances our understanding of neurodegenerative disease etiology.

description: In a recent paper, Matl et al present a high-frequency study of the complex resistivity of a pinned vortex lattice in YBaCuO . They focus on the inductive-to-resistive transition which is investigated as a function of temperature at a constant field $B_0=2$ T, so that the transition is associated with the vanishing of vortex pinning strength. To our view, their conclusions rely on a rather brittle experimental body and the collapse of C66 results from an involved analysis of the finite frequency corrections to $ρ(ω)$. These corrections are not necessary since the complex frequency spectrum has been previously interpreted by the two modes model, first proposed for low Tc materials. We think that it is more adequate to interpret the present data and should be at least considered.

description: Metabolic zonation refers to the spatial separation of metabolic functions along the sinusoidal axes of the liver. This phenomenon forms the foundation for adjusting hepatic metabolism to physiological requirements in health and disease (e.g., metabolic dysfunction-associated steatotic liver disease/MASLD). Zonated metabolic functions are influenced by zonal morphological abnormalities in the liver, such as periportal fibrosis and pericentral steatosis. We aim to analyze the interplay between microperfusion, oxygen gradient, fat metabolism and resulting zonated fat accumulation in a liver lobule. Therefore we developed a continuum biomechanical, tri-phasic, bi-scale, and multicomponent in silico model, which allows to numerically simulate coupled perfusion-function-growth interactions two-dimensionally in liver lobules. The developed homogenized model has the following specifications: (i) thermodynamically consistent, (ii) tri-phase model (tissue, fat, blood), (iii) penta-substances (glycogen, glucose, lactate, FFA, and oxygen), and (iv) bi-scale approach (lobule, cell). Our presented in silico model accounts for the mutual coupling between spatial and time-dependent liver perfusion, metabolic pathways and fat accumulation. The model thus allows the prediction of fat development in the liver lobule, depending on perfusion, oxygen and plasma concentration of free fatty acids (FFA), oxidative processes, the synthesis and the secretion of triglycerides (TGs). The use of a bi-scale approach allows in addition to focus on scale bridging processes. Thus, we will investigate how changes at the cellular scale affect perfusion at the lobular scale and vice versa. This allows to predict the zonation of fat distribution (periportal or pericentral) depending on initial conditions, as well as external and internal boundary value conditions.

description: Recent work in decentralized, schedule-driven tra ffic control
has demonstrated the ability to improve the effi ciency of traffic flow in complex urban road networks. In this approach, a scheduling agent is associated with each intersection. Each agent senses the traffic approaching its intersection and in real-time constructs a schedule that minimizes the cumulative wait time of vehicles approaching the intersection over the current look-ahead horizon. In order to achieve network-level coordination in a scalable manner, scheduling agents communicate only with their direct neighbors.
Each time an agent generates a new intersection schedule it communicates its expected out flows to its downstream neighbors as a prediction of future demand and these out
flows are appended to the downstream agent's locally perceived demand. In this thesis, we study how to upgrade the network-level coordination of schedule-driven tra ffic control to tackle increasingly serious traffi c congestion from three aspects: stability, optimality and learnability. For stability, a hybrid approach that incorporates
the stability of queuing theory into a schedule-driven control
framework is proposed. For optimality, the basic coordination protocol is extended to additionally incorporate the complementary flow of information re
effective of an intersection's current congestion level to its upstream neighbors. We propose an asynchronous
decentralized algorithm in order to approach networkwide
optimality. In addition, we show that integrating connected
and autonomous vehicles with the intersection control could provide bene fits for further improving performance. To present its learnability, we study a parameter learning problem to confi gure maximum green time by a fully decentralized reinforcement learning algorithm and a timing prediction problem utilizing the cluster representation for scheduling approaching vehicles. The goal of this thesis is to demonstrate the capability of schedule driven traffic control to mitigate urban network congestion. To
achieve this goal, we leverage the techniques originated from online planning, distributed optimization and reinforcement learning as well as incorporate the new technologies including connected and autonomous vehicles into the schedule-driven framework.

description: The mouse olfactory system detects odorants with 1000 olfactory receptors (ORs). Olfactory sensory neurons (OSNs) express only 1 OR. OSNs expressing a common OR converge on a single glomerulus, a stereotyped location in the olfactory bulb (OB). Thus, odorants are represented by a spatial map of glomerular activation. OB odor representations are then processed by five central brain regions. One region, cortical amygdala (CoA), receives spatially patterned and stereotyped axonal input from the OB and is both necessary and sufficient for innate behavioral responses to odor. However, CoA receives input from all glomeruli and forms a representation of every odor. It is not known why all odors are represented in CoA or how some odor representations elicit behavior while others do not. One hypothesis is that only rare neurons in CoA, not activated by most odors, participate in innate signaling. Another hypothesis is that all neurons in CoA participate in innate signaling, but for many odors, opposing CoA outputs cancel out downstream. These hypotheses were addressed by single nuclei sequencing and in situ hybridization which identified and localized neuronal cell types within CoA. Cell types are topographically segregated in regions well positioned to differentially receive inputs from genetically defined subsets of glomeruli. Therefore, the connectivity between OB and CoA may instantiate a genetically wired circuit from OB to cortex for innate odor processing. A number of rare and common cell types were identified. Thus, CoA may process two types of innate signals: (1) specific innate signals, produced by few glomeruli and processed by rare CoA cell types; (2) broad innate signals, produced by many glomeruli and processed by common CoA cell types through the integration of probabilistic information about the value of odorants.

description: Quantum low-density parity-check codes can be decoded using a syndrome based $\mathrm{GF}(4)$ belief propagation decoder. However, the performance of this decoder is limited both by unavoidable $4$-cycles in the code's factor graph and the degenerate nature of quantum errors. For the subclass of CSS codes, the number of $4$-cycles can be reduced by breaking an error into an $X$ and $Z$ component and decoding each with an individual $\mathrm{GF}(2)$ based decoder. However, this comes at the expense of ignoring potential correlations between these two error components. We present a number of modified belief propagation decoders that address these issues. We propose a $\mathrm{GF}(2)$ based decoder for CSS codes that reintroduces error correlations by reattempting decoding with adjusted error probabilities. We also propose the use of an augmented decoder, which has previously been suggested for classical binary low-density parity-check codes. This decoder iteratively reattempts decoding on factor graphs that have a subset of their check nodes duplicated. The augmented decoder can be based on a $\mathrm{GF}(4)$ decoder for any code, a $\mathrm{GF}(2)$ decoder for CSS code, or even a supernode decoder for a dual-containing CSS code. For CSS codes, we further propose a $\mathrm{GF}(2)$ based decoder that combines the augmented decoder with error probability adjustment. We demonstrate the performance of these new decoders on a range of different codes, showing that they perform favorably compared to other decoders presented in literature.

Remedial works implementation at the Britannia Mine remediation project
Creators: name: O'Hara, Gerry
Publisher: name: The University of British Columbia
Year: 2009

description: The BC Ministry of Agriculture and Lands (the Province), is undertaking a program of environmental remediation at Britannia Mine, located 45 km north of Vancouver, BC. The Britannia Mine operated for 70 years and produced mainly copper and zinc concentrates. During its operating life, and since its closure in 1974, the mine has discharged large volumes of acidic water, elevated in metals toxic to aquatic life, including copper, zinc and cadmium. Metal loadings to Howe Sound average some 300 kg/day each of copper and zinc. The Province’s remedial concept uses the mine workings as a storage reservoir balancing seasonal flows to a water treatment plant prior to discharge to Howe Sound. In addition to the acid rock drainage (ARD) from the mine, mine infrastructure and mineral processing activities provide secondary sources of metal contamination of soils, groundwater and surface water. The major investigation phase of the project completed in 2002 and remedial planning and implementation commenced in early-2003. Remediation works include a novel groundwater management system, surface and storm water drainage, relocation and management of ~35,000m³ of metal-contaminated soils, surface water diversions and construction of a high-density sludge water treatment plant and deep outfall, the latter scheduled for completion in November, 2005.

description: We examine some of the subtleties inherent in formulating a theory of spinors on a manifold with a smooth degenerate metric. We concentrate on the case where the metric is singular on a hypersurface that partitions the manifold into Lorentzian and Euclidean domains. We introduce the notion of a complex spinor fibration to make precise the meaning of continuity of a spinor field and give an expression for the components of a local spinor connection that is valid in the absence of a frame of local orthonormal vectors. These considerations enable one to construct a Dirac equation for the discussion of the behavior of spinors in the vicinity of the metric degeneracy. We conclude that the theory contains more freedom than the spacetime Dirac theory and we discuss some of the implications of this for the continuity of conserved currents.

description: Taking the model system of an oxide containing acceptor dopant cations and charge-compensating oxygen vacancies, we calculate at the continuum level the change in the excess grain-boundary energy of an ionic solid upon space-charge formation. Two different cases are considered for the space-charge layers: (i) only vacancies attain electrochemical equilibrium and (ii) both dopants and vacancies attain electrochemical equilibrium. The changes calculated for a specific set of grain boundaries indicate that, depending on dopant concentration, space-charged formation can decrease the excess free energy by up to 15% in the first case and by up to 45% in the second case. The possibility of the excess grain-boundary energy going to zero and the possible effects of an external electric field on the excess grain-boundary energy are also discussed.This article is part of the discussion meeting issue ‘Energy materials for a low carbon future’.

description: Food losses refer to edible food mass decrease throughout the human food chain. Food losses occurring at consumption stage are called food waste. Food Losses and Waste (FLW) represent one of the most critical social, economic and ecological challenges facing humanity, besides being also an ethical issue. FAO data show that roughly one-third of food produced for human consumption is lost or wasted. There are no precise and accurate data regarding food waste in Near East and North Africa (NENA) region. The review paper aims at providing insights about the extent of FLW in NENA region with a special focus on Arab countries and Iran. The paper explores linkages between food waste and food security. Moreover, it analyses the economic and environmental implications of FLW. FLW vary depending on food type, country and season. Generally speaking, postharvest losses are significant in this region for most of commodity groups. It is estimated that FLW amount to 34% of food supply in NENA region. FLW undermine the very foundations of food security and amount to major depletion of resources (e.g. water, land, energy) and produce needlessly greenhouse gases. They also represent a wasted investment that reduces farmers’ incomes and increase consumers’ expenses. Therefore, food waste reduction is crucial for improving the sustainability of the food supply chain and achieving food and nutrition security in the region.

description: We show that the braided tensor product algebra $A_1\underline{\otimes}A_2$ of two module algebras $A_1, A_2$ of a quasitriangular Hopf algebra $H$ is equal to the ordinary tensor product algebra of $A_1$ with a subalgebra of $A_1\underline{\otimes}A_2$ isomorphic to $A_2$, provided there exists a realization of $H$ within $A_1$. In other words, under this assumption we construct a transformation of generators which `decouples' $A_1, A_2$ (i.e. makes them commuting). We apply the theorem to the braided tensor product algebras of two or more quantum group covariant quantum spaces, deformed Heisenberg algebras and q-deformed fuzzy spheres.

 COLOMBIA: Cundinamarca Department, Tena; 13 December 2020, 1551; J. N. Rozo Pinilla. Host: Ctenus sp. (Ctenidae), adult or subadult female. The wasp straddled the immobilized wandering spider, dorsal side upward, and grasped the patella of its left foreleg with her mandibles. She then walked to the front of the spider, grasped its chelicera with her mandibles, and turned it onto its back, ventral side upward. Maintaining this grasp of the spider, she walked forward into dense vegetation, occasionally pausing and walking backwards for a short distance before turning around and walking forward (Fig. 5; Rozo Pinilla 2020).

Neuronal Laterality in Caenorhabditis elegans: Morphological and Functional Aspects

description: The ASE neurons of C. elegans are an excellent model to study neuronal asymmetry. Lateralization with respect to their genetic fate and function has been well studied, but their more subtle asymmetries have not. This work describes three such asymmetries: that of amino acid gustation, associative learning, and morphological size. In the first two of these, I found a previously uncharacterized asymmetric neuronal response with respect to amino acid gustation, and expand on the known asymmetry with respect to associative salt learning. Most of this thesis focuses on a discovered size asymmetry in the ASE pair of neurons: characterizing it, providing a functional significance, and describing some of its genetic underpinnings. Size asymmetry and the mechanisms of overall neuron growth are not well-studied, but do have functional consequences in higher organisms. This work hopefully furthers our understandings of these processes and of neuronal development in general.
White garments, petticoats and straw hats: analysing sartorial clues in Wilkie Collins’s The Woman in White
Creators: name: Sarnelli, Debora A.
Publisher: name: La camera blu
Year: 2022

description: The aim of the research is to present and discuss the symbolic dimension clothes acquire in relation to the mains characters of Wilkie Collins’s novel, The Woman in White. The clothes examined reveal the characters’ emotions, intent and personality. Anne and Laura’s white clothes will be the first to be examined as means used by the villains to both change and control their identities. The research will then shed a light on the clothes Marian and Fosco, two ambiguously gendered characters, wear to discuss their gender liminality and the impossibility to categorise them within traditional markers of gender. Ultimately, clothes as symbols of patriarchal authority will be considered, with reference to two marginalised female figures, Madame Fosco and Mrs Catherick.

Effective interactions and phase behaviour for a model clay suspension in an electrolyte

description: Since the early observation of nematic phases of disc-like clay colloids by Langmuir in 1938, the phase behaviour of such systems has resisted theoretical understanding. The main reason is that there is no satisfactory generalization for charged discs of the isotropic DLVO potential describing the effective interactions between a pair of spherical colloids in an electrolyte. In this contribution, we show how to construct such a pair potential, incorporating approximately both the non-linear effects of counter-ion condensation (charge renormalization) and the anisotropy of the charged platelets. The consequences on the phase behaviour of Laponite dispersions (thin discs of 30 nm diameter and 1 nm thickness) are discussed, and investigation into the mesostructure via Monte Carlo simulations are presented.

Multi-quark matrix elements in the proton and three gluon exchange for exclusive $η_c$ production in photon-proton diffractive scattering

description: Exclusive production of a $η_c$ pseudo-scalar meson in $γ^{(*)} + p \to η_c + p$ scattering at high energies involves a ${\cal C}$-odd exchange in the $t$-channel. We formulate the description of this process within the high-energy framework of eikonal dipole scattering. We obtain expressions for the light-cone wave function of the $η_c$ required in this framework as well as for the ${\cal C}$-odd amplitudes due to exchange of a single photon, of a photon plus two gluons, and of three gluons. We relate these amplitudes to correlators of the $+$ component of the quark current in the light-cone wave function of the proton. For high transverse momenta these correlators correspond to Generalized Parton Distributions (GPDs) given by diagrams where all exchanged gauge bosons attach to a single quark in the proton. Diagrams involving multi-quark matrix elements potentially sensitive to correlations, screen infrared singularities. Moreover, they are numerically important for configurations where the exchanged bosons nearly share the total momentum transfer. Using two simple models for the three quark Fock state of the proton at $x\simeq0.1$, we find that single photon exchange dominates for $|t|<1.5$~GeV$^2$. Here, the quark GPD could be measured cleanly in $γ^{(*)} + p \to η_c + p$ via single photon exchange. For higher momentum transfer three gluon (`Odderon') exchange is dominant.

description: Multistep dynamical phase transition from the locked to the running state of atoms in response to a dc external force is studied by MD simulations of the generalized Frenkel-Kontorova model in the underdamped limit. We show that the hierarchy of transition recently reported [Braun et al, Phys. Rev. Lett. 78, 1295 (1997)] strongly depends on the value of the friction constant. A simple phenomenological explanation for the friction dependence of the various critical forces separating intermediate regimes is given.

description: Brain diseases including neurological disorders and tumors remain undertreated due to the challenge in accessing the brain, and blood-brain barrier (BBB) restricting drug delivery, which also profoundly limits the development of pharmacological treatment. Focused ultrasound (FUS) with acoustic agents including microbubbles and nanodroplets remains as the only method to open the BBB noninvasively, locally, and transiently to assist drug delivery. For an ideal medical system to serve a broad patient population, it requires precise and flexible targeting with simulation to personalize treatment, real-time monitoring to ensure safety and effectiveness, and rapid application, as repetitive pharmacological treatment is often required. Since none of current systems fulfills all the requirements, here we designed a neuronavigation-guided FUS system with protocol assessed in in vivo mice, in vivo non-human primates, and human skulls from in silico preplanning, online FUS treatment and real-time acoustic monitoring and mapping, to post-treatment assessment using MRI. Both sedate and awake non-human primates were evaluated with total treatment time averaging 30 min and 3-mm targeting accuracy in cerebral cortex and subcortical structures. The FUS system developed would enable transcranial FUS in patients with high accuracy and independent of MRI guidance.
On the Quantum Levels of Isolated Spherically Symmetric Gravitational Systems

description: The known canonical quantum theory of a spherically symmetric pure (Schwarzschild) gravitational system describes isolated black holes by plane waves exp(-iMc^2τ/\hbar) with respect to their continuous masses M and the proper time τof obsevers at spatial infinity. On the other hand Bekenstein and Mukhanov postulated discrete mass levels for such black holes in the spirit of the Bohr-Sommerfeld quantisation in atomic physics. The two approaches can be related by postulating periodic boundary conditions in time for the plane waves and by identifying the period Δin real time with the period Δ_H= 8πGM/c^3 in Euclidean time. This yields the mass spectrum M_n=(1/2)\sqrt{n}m_P, n=1,2,... .

At most 27 length inequalities define Maskit's fundamental domain for the modular group in genus 2

description: In recently published work Maskit constructs a fundamental domain D_g for the Teichmueller modular group of a closed surface S of genus g>1. Maskit's technique is to demand that a certain set of 2g non-dividing geodesics C_{2g} on S satisfies certain shortness criteria. This gives an a priori infinite set of length inequalities that the geodesics in C_{2g} must satisfy. Maskit shows that this set of inequalities is finite and that for genus g=2 there are at most 45. In this paper we improve this number to 27. Each of these inequalities: compares distances between Weierstrass points in the fundamental domain S-C_4 for S; and is realised (as an equality) on one or other of two special surfaces.
