description: A Bose-Einstein condensate in an external potential consisting of a superposition of a harmonic and a random potential is considered theoretically. From a semi-quantitative analysis we find the size, shape and excitation energy as a function of the disorder strength. For positive scattering length and sufficiently strong disorder the condensate decays into fragments each of the size of the Larkin length ${\cal L}$. This state is stable over a large range of particle numbers. The frequency of the breathing mode scales as $1/{\cal L}^2$. For negative scattering length a condensate of size ${\cal L}$ may exist as a metastable state. These finding are generalized to anisotropic traps.

description: Given an i.i.d. sample drawn from a density $f$, we propose to test that $f$ equals some prescribed density $f_0$ or that $f$ belongs to some translation/scale family. We introduce a multiple testing procedure based on an estimation of the $\mathbb{L}_2$-distance between $f$ and $f_0$ or between $f$ and the parametric family that we consider. For each sample size $n$, our test has level of significance $α$. In the case of simple hypotheses, we prove that our test is adaptive: it achieves the optimal rates of testing established by Ingster [J. Math. Sci. 99 (2000) 1110--1119] over various classes of smooth functions simultaneously. As for composite hypotheses, we obtain similar results up to a logarithmic factor. We carry out a simulation study to compare our procedures with the Kolmogorov--Smirnov tests, or with goodness-of-fit tests proposed by Bickel and Ritov [in Nonparametric Statistics and Related Topics (1992) 51--57] and by Kallenberg and Ledwina [Ann. Statist. 23 (1995) 1594--1608].

description: We study the gluonic color-spin locked (GCSL) phase in dense two-flavor quark matter. In this phase, the color and spatial rotational symmetries are spontaneously broken down to SO(2)_{diag} with the generator being an appropriate linear combination of the color and rotational ones. The Meissner masses of gluons and the mass of the radial mode of the diquark field in the GCSL phase are calculated and it is shown that this phase is free from the chromomagnetic and Sarma instabilities in the whole parameter region where it exists. The GCSL phase describes an anisotropic color and electromagnetic superconducting medium. Because most of the initial symmetries in this phase are spontaneously broken, its dynamics is very rich.

description: Abstract: - The human microbiome, a complex ecosystem of microorganisms residing in and on the body, plays a crucial role in maintaining health and preventing disease. Recent advances in metagenomic technologies have revolutionized our understanding of microbial diversity and functionality, revealing intricate interactions between the microbiome and host physiology. Dysbiosis, or the imbalance of microbial communities, is associated with various health conditions, including obesity, inflammatory bowel disease, and mental health disorders. This review explores the significance of the microbiome in health and disease, the mechanisms underlying microbial diversity, and the implications of dysbiosis for disease pathogenesis. Furthermore, it highlights potential therapeutic interventions, including probiotics, prebiotics, and fecal microbiota transplantation, while discussing future directions in microbiome research. Understanding the multifaceted roles of the microbiome could lead to innovative approaches for disease prevention and treatment.

description: Philonthus rectangulus Sharp, 1874 NOVA SCOTIA: Kings Co.: Grand Pré, 19.VII.1952, F.L. Trenholm, (1, NSAC). Majka and Klimaszewski (2008) recorded P. rectangulus from Nova Scotia from specimens collected in 2004. Th e above record establishes the presence of this species in the province in 1952, 52 years earlier than previously reported, and 25 years earlier than the previous earliest record from the Maritime Provinces in 1977 from New Brunswick (Majka and Klimaszewski 2008). It appears to originally have been native to Japan before spreading to China in 1901, arriving in Europe in 1916. The earliest records from North America are from 1908 in Oregon (Smetana 1995). It now is widely distributed across the Palaearctic region, including China and Japan in the east. It is also known from many other parts of the world and is considered a cosmopolitan species (Herman 2001; Smetana 2004b). It is found in all kinds of decaying organic matter, particularly in synanthropic situations, and is particularly common in animal dung, compost, and rotting plant debris (Smetana 1995).

Daylighting in atrium spaces
Creators: name: Iyer, Usha
Publisher: name: University of British Columbia
Year: 2010

description: Among the different environmental functions atria perform, this research has focused only on daylighting. The thesis has been presented in two parts. The first part provides the background information, the extent of daylighting research in atria, objective and scope of the research. The environmental role of atria has also been discussed. The second part deals with the research procedure, the description of the scale model used for the study, the conditions under which the study have been conducted, and finally, the conclusions of the study. The effects of changing the reflectivity of the wall and floor surfaces of the atria well on the illumination in the adjacent spaces to atria have been studied. The objective of the thesis was to establish the relative contributions of the changes in the surface reflectance of the wall and the effects of variations in the area of the openings in the wall facade on lighting in the adjacent occupied spaces. The importance of the floor reflectivity in lighting the spaces adjacent to the atria was also determined. Quantitative analysis of daylighting in atria has been conducted using physical scale models under natural overcast skies using daylight factor and well index to normalize the results. Although the thesis has concentrated on daylighting, in reality there are other functions, both social and environmental, that atria are required to perform, and where appropriate, these functions have been acknowledged. It has been established by this research, that the atria well and the spaces adjacent to it are affected by changes in the area of openings in the form of windows in the wall facades of the well. Small variations in higher reflective surfaces on the wall facade produce greater differences in the daylight factors as compared to similar differences in surfaces with lower reflectances. Using high surface reflectance on the floor of the atria well will enhance illumination in the lower levels of the atria. As the area of the (high) reflective surfaces along the edges of the floor is increased, the illumination in the side spaces in the lower levels also increases. The area of floor reflectivity needed for increasing the illumination levels in the side spaces is dependent on the area of openings on the walls at the lower levels.

description: We consider the Fermi surface inside the antiferromagnetic ordered region of a Kondo lattice system in an arbitrary dimension higher than one. We establish the existence of ${\rm AF_S}$, an antiferromagnetic phase whose Fermi surface is ``small,'' in the sense that the local moments do not participate in the Fermi-surface formation. This is in contrast to the ``large'' Fermi surface that is typically assumed for heavy fermion metals. We extend our earlier work to the case that the Fermi surface of the conduction electrons intersects the antiferromagnetic Brillouin zone boundary. Our results provide a new perspective on local quantum criticality. In addition, our results imply that, for the ${\rm AF_S}$ phase, it is important to keep track of the dynamical screening processes; we suggest that this effect is not captured in a recent variational Monte-Carlo study of the Kondo lattice.

Reformulating SU(N) Yang-Mills theory based on change of variables

Year: 2008
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We propose a new version of SU(N) Yang-Mills theory reformulated in terms of new field variables which are obtained by a nonlinear change of variables from the original Yang-Mills gauge field. The reformulated Yang-Mills theory enables us to study the low-energy dynamics by explicitly extracting the topological degrees of freedom such as magnetic monopoles and vortices to clarify the mechanism for quark confinement. The dual superconductivity in Yang-Mills theory is understood in a gauge-invariant manner, as demonstrated recently by a non-Abelian Stokes theorem for the Wilson loop operator, although the basic idea of this reformulation is based on the Cho-Faddeev-Niemi decomposition of the gauge potential.

Studies on the processing of rubella virus structural proteins by analysis of the endoproteolytic cleavage sites
Creators: name: McDonald, Helen L
Publisher: name: University of British Columbia
Year: 2010

description: Rubella virus is a small enveloped positive strand RNA virus. Two species of viral RNA are found in infected cells: a full-length genomic RNA and a subgenomic species corresponding to the 3' one third of the genomic RNA molecule. The 24S subgenomic RNA specifies a polyprotein which is cotranslationally processed by endoproteolytic cleavage by host signal peptidase to yield three structural proteins, El, E2 and capsid. El and E2 are membrane glycoproteins forming the virion spikes, and C protein binds to 40S genomic RNA to form a nucleocapsid. El and E2 proteins contain N-linked oligosaccharide as a consequence of their passage through the endoplasmic reticulum (ER) and Golgi apparatus. According to the signal hypothesis, translocation of secretory and membrane proteins into the ER is mediated by a hydrophobic signal peptide. The signal peptides for E2 and El have been localized by in vivo expression of El and E2 cDNAs. Oligonucleotide-directed mutagenesis was used to define the cleavage sites between C, E2, and El, as well as the effect of the cleavages on the transport and processing of E2 and El. The expression of the cleavage site mutants was studied in vitro and in vivo. It was found that uncleaved precursor polypeptides were retained in the ER and very little E2 or El polypeptide was observed at either the Golgi apparatus or the plasma membrane. The E2 and El polypeptides can cross the ER membrane without the cleavage of the signal peptide while the transport of E2 and El beyond the ER requires the cleavage of E2 from C and El from E2. The C-termini of the C and E2 proteins, which were not previously defined, have been partially characterized. Capsid protein does not appear to undergo further proteolytic processing after it is cleaved from E2 by signal peptidase, but E2 may be processed at a second cleavage site at its C-terminus by a trypsin-like enzyme.

Effect of temperature and molt stage on ion regulation of the Dungeness crab: characterisation of cation transporting ATPases
Creators: name: Marta, Malinowska
Publisher: name: Zenodo
Year: 2022
Subjects: cation transporting ATPases, molt cycle, thermal acclimation, Metacarcinus magister, metabolic cold compensation

description: Periodically, crustaceans have to shed their old exoskeleton and synthesize a new one in order to grow, in a process called molting. This requires the transfer of massive quantities of ions through the body what is mediated by ion transporting ATPases.Temperature affects these enzymes however, it is essential for the ectothermic animals to maintain ion homeostasis within stable range. Using samples from a preceding exposure experiment, maximal ATPase capacities of the Na+/K+-ATPase and an Mg2+-ATPase were determined in the hepatopancreas of thermally acclimated crabs (10°,15° and 20°C) which additionally differed by their molt stage (C, D0, D1, D2). Na+/K+-ATPase activity assay revealed that it’s capacity increased with proceeding molt cycle. Warm acclimated animals responded less than the cold-acclimated animals, demonstrating some level of metabolic cold compensation. Mg2+ dependent activity was low in comparison to the Na+/K+-ATPase activity, in line with the assumption that the uptake of Mg2+ by the animal is not that critical than a Na+ gradient facilitated Ca2+ uptake. A set of inhibitors were identified (vanadate, PMSF
 and soy bean trypsin inhibitor), to stabilize the hepatopancreatic extracts and allowing to quantify the Na+/K+ -ATPase protein expression. Na+/K+-ATPase protein expression increased with proceeding molt cycle, and warm acclimated animals responded less than the cold-acclimated animals. Correlation analyses of enzyme function, protein expression and mRNA expression were also performed. Overall, the correlation between mRNA and activity was quite strong, indicating a transcriptional control of the Na+/K+-ATPase function. The weaker correlations between mRNA vs. protein and protein vs. activity may be caused by some methodological concerns. This study provides some first evidence about molt stage and temperature dependent ATPase function and its regulation in the crab Metacarcinus magister. A significant interaction of these two factors seem to exist, which may affect the ability of the crab to molt in a changing climate.

description: We study the rational cohomology groups of the real De Concini-Procesi model corresponding to a finite Coxeter group, generalizing the type-A case of the moduli space of stable genus 0 curves with marked points. We compute the Betti numbers in the exceptional types, and give formulae for them in types B and D. We give a generating-function formula for the characters of the representations of a Coxeter group of type B on the rational cohomology groups of the corresponding real De Concini-Procesi model, and deduce the multiplicities of one-dimensional characters in the representations, and a formula for the Euler character. We also give a moduli space interpretation of this type-B variety, and hence show that the action of the Coxeter group extends to a slightly larger group.

The uvbyHbeta Metallicity Calibration for G and K Dwarfs

Publisher: name: arXiv

description: The metallicity dependence of the primary indices of the uvby photometric system for cooler dwarfs (Teff ~ 6500 K to 5000K) is investigated. The data base for the analysis is composed of the overlap between a composite catalog of selected, high-dispersion spectroscopic abundances for 1801 stars on the metallicity scale of Valenti and Fischer (2005) and a merged catalog of high-precision uvbyHbeta photometry for over 35,000 stars. While [Fe/H] for F dwarfs is best estimated from m_1, with a modest dependence on c_1 as expected, for hotter G dwarfs the pattern reverses and c_1 becomes the dominant index. For cooler G dwarfs and K stars, the c_1 dominance continues, but a discontinuity appears such that stars between (b-y) = 0.50 and 0.58 with [Fe/H] >= +0.25 have m_1 and c_1 indices that classify them as subgiants, confirming an earlier result based upon a much smaller sample. The reversal in the sensitivity to m_1 and c_1 is traced, in part, to the metallicity sensitivity of the (b-y) index. Moreover, (b-y) grows larger in a non-linear fashion for stars above solar metallicity, leading to an overestimate of the reddening for super-metal-rich stars from some standard intrinsic color relations. Based upon successful tests using indices from synthetic spectra and the empirical trends among the observations, metallicity calibrations tied to Hbeta rather than (b-y) have been derived for [Fe/H] >= -1.0, generating dispersions among the residuals ranging from 0.061 dex to 0.085 dex over the entire temperature range of interest. The new calibrations have the added advantage of being significantly less sensitive to errors in reddening than previous calibrations.

Identity, place, power and the 'text' : Kerry's Dale and the "monster" house
Creators: name: Majury, Niall Charles
Publisher: name: University of British Columbia
Year: 2010

description: Since the late 1960's, fundamental changes in Canadian immigration policy, encouraging more middle-class/professional immigration in an effort to create employment and to boost the nation's skill profile, have precipitated a shift in orientation of population and capital flows into Canada. In particular the countries of the Pacific Rim have risen in relative importance as source regions of both international finance and migrants. These trends have had an uneven impact across Canada, and Vancouver in particular has come to play a significant role as a "gateway city". This thesis considers some of the ramifications of the emerging social geography of this elite portion of the wide spectrum of immigrants entering Canada. In focusing on neighbourhood change within the upper middle-class suburb of Kerrisdale, situated on Vancouver's elite West Side, it examines the cultural politics surrounding perceived social change. It explores a contested sense of identity and place, showing how these are informed and invigorated by a diverse set of social struggles evident in conflicting landscape 'tastes' in the neighbourhood of Kerrisdale.

Fluctuations and Pattern Formation in Fluids with Competing Interactions

description: One of the most interesting phenomena in the soft-matter realm consists in the spontaneous formation of super-molecular structures (microphases) in condition of thermodynamic equilibrium. A simple mechanism responsible for this self-organization or pattern formation is based on the competition between attractive and repulsive forces with different length scales in the microscopic potential, typically, a short-range attraction against a longer-range repulsion. We analyse this problem by simulations in 2D fluids. We find that, as the temperature is lowered, liquid-vapor phase separation is inhibited by the competition between attraction and repulsion, and replaced by a transition to non-homogeneous phases. The structure of the fluid shows well defined signatures of the presence of both intra- and inter-cluster correlations. Even when the competition between attraction and repulsion is not so strong as to cause microphase formation, it still induces large density fluctuations in a wide region of the temperature-density plane. In this large-fluctuation regime, pattern formation can be triggered by a weak external modulating field.

description: The diversity of lignan small molecules derived from podophyllotoxin, a non-covalent tubulin inhibitor isolated from the Podophyllum family, has led to the clinical development of FDA-approved anticancer agents etoposide and teniposide. While these two compounds share the same tetracyclic core as podophyllotoxin, two subtle structural changes—4’ demethylation on the aromatic ring and stereospecific glycosylation at the C-4 hydroxyl—result in an alternate biological mechanism. Given the immense pharmacological importance of altering the C-4 position, we synthesised and evaluated a systematic library of diversified esters to establish a structure-activity relationship regarding modification at C-4 on the properties of podophyllotoxin. We determined the biological activity of these esters through cell viability assays, computer docking models, tubulin polymerisation assays, and cell cycle analysis. Altogether, we demonstrate that increasing steric hindrance at C-4 leads to a loss in potency against human cancer cells but has a significantly lesser impact on cell-free tubulin inhibition.

description: We present results of theoretical description of ultrasonic phenomena in molecular liquids. In particular, we are interested in the development of microscopical, i.e., statistical-mechanical framework capable to explain the long living puzzle of the excess ultrasonic absorption in liquids. Typically, ultrasonic wave in a liquid can be generated by applying the periodically alternating external pressure with the angular frequency that corresponds to the ultrasound. If the perturbation introduced by such process is weak - its statistical-mechanical treatment can be done with the use of the linear response theory. We treat the liquid as a system of interacting sites, so that all the response/aftereffect functions as well as the energy dissipation and generalized (wave-vector and frequency dependent) ultrasonic absorption coefficient are obtained in terms of familiar site-site static and time correlation functions such as static structure factors or intermediate scattering functions. To express the site-site intermediate scattering functions we refer to the site-site memory equations in the mode-coupling approximation for the first-order memory kernels, while equilibrium properties such as site-site static structure factors, direct and total correlation functions are deduced from the integral equation theory of molecular liquids known as RISM or one of its generalizations. All the formalism is phrased in a general manner, hence the obtained results are expected to work for arbitrary type of molecular liquid including simple, ionic, polar, and non-polar liquids.

description: We present a model unifying general relativity and quantum mechanics. The model is based on the (noncommutative) algebra \mbox{\cal A} on the groupoid Γ= E \times G where E is the total space of the frame bundle over spacetime, and G the Lorentz group. The differential geometry, based on derivations of \mbox{\cal A}, is constructed. The eigenvalue equation for the Einstein operator plays the role of the generalized Einstein's equation. The algebra \mbox{\cal A}, when suitably represented in a bundle of Hilbert spaces, is a von Neumann algebra \mathcal{M} of random operators representing the quantum sector of the model. The Tomita-Takesaki theorem allows us to define the dynamics of random operators which depends on the state ϕ. The same state defines the noncommutative probability measure (in the sense of Voiculescu's free probability theory). Moreover, the state ϕsatisfies the Kubo-Martin-Schwinger (KMS) condition, and can be interpreted as describing a generalized equilibrium state. By suitably averaging elements of the algebra \mbox{\cal A}, one recovers the standard geometry of spacetime. We show that any act of measurement, performed at a given spacetime point, makes the model to collapse to the standard quantum mechanics (on the group G). As an example we compute the noncommutative version of the closed Friedman world model. Generalized eigenvalues of the Einstein operator produce the correct components of the energy-momentum tensor. Dynamics of random operators does not ``feel'' singularities.

On sparse representations of linear operators and the approximation of matrix products

description: Thus far, sparse representations have been exploited largely in the context of robustly estimating functions in a noisy environment from a few measurements. In this context, the existence of a basis in which the signal class under consideration is sparse is used to decrease the number of necessary measurements while controlling the approximation error. In this paper, we instead focus on applications in numerical analysis, by way of sparse representations of linear operators with the objective of minimizing the number of operations needed to perform basic operations (here, multiplication) on these operators. We represent a linear operator by a sum of rank-one operators, and show how a sparse representation that guarantees a low approximation error for the product can be obtained from analyzing an induced quadratic form. This construction in turn yields new algorithms for computing approximate matrix products.

The adherence of Acidiphilium cryptum to chalcopyrite
Creators: name: Heffelfinger, Blair
Publisher: name: University of British Columbia
Year: 2010

description: Acidiphilium cryptum is a heterotrophic acidophile commonly found in acidic environments and industrial bioleaching operations. Attachment to mineral surfaces may serve to maintain this organism in aqueous environments where it is subject to removal by hydrodynamic forces. Using indirect and direct methods we have looked at the binding of A.cryptum to chalcopyrite (CuFeS₂) and other mineral ores to determine whether specific adhesins mediate binding. A modified ELISA binding assay (the Ore ELISA) was developed to measure direct adherence. Finely ground chalcopyrite was bound irreversibly to the walls of an ELISA plate, the organisms were added and after incubation and washing, the number of attached bacteria were assessed by reacting with anti-A.cryptum antibody followed by goat anti-rabbit IgG conjugated to alkaline phosphatase. This assay was found to be sensitive, rapid and reproducible. The Ore ELISA allowed direct binding measurement in the presence of various inhibitors and provided a rapid screening method for adherence-defective mutants. Adherence was shown to be saturable and increased slightly as pH decreased. A moderate increase in binding affinity was recorded in the presence of monovalent and divalent cations and EDTA. Various bactericidal agents and pentose and hexose sugars had no effect on chalcopyrite attachment. Reducing agents had little effect on cell adherence. A strong increase in adherence was observed in the presence of surface active agents. Bovine serum albumin and gelatin were both found to markedly reduce mineral surface binding. Competition for attachment sites between A.cryptum and the autotrophic acidophile, Thiobacillus ferrooxidans, showed that each organism binds to unique sites on the chalcopyrite surface. A.cryptum mutant strains displaying reduced adherence to chalcopyrite were shown to lack a 31.6 kDa outer membrane protein.

description: Open Source Software (OSS) development challenges traditional software engineering practices. In particular, OSS projects are managed by a large number of volunteers, working freely on the tasks they choose to undertake. OSS projects also rarely rely on explicit system-level design, or on project plans or schedules. Moreover, OSS developers work in arbitrary locations and collaborate almost exclusively over the Internet, using simple tools such as email and software code tracking databases (e.g. CVS). All the characteristics above make OSS development akin to weaving a tapestry of heterogeneous components. The OSS design process relies on various types of actors: people with prescribed roles, but also elements coming from a variety of information spaces (such as email and software code). The objective of our research is to understand the specific hybrid weaving accomplished by the actors of this distributed, collective design process. This, in turn, challenges traditional methodologies used to understand distributed software engineering: OSS development is simply too "fibrous" to lend itself well to analysis under a single methodological lens. In this paper, we describe the methodological framework we articulated to analyze collaborative design in the Open Source world. Our framework focuses on the links between the heterogeneous components of a project's hybrid network. We combine ethnography, text mining, and socio-technical network analysis and visualization to understand OSS development in its totality. This way, we are able to simultaneously consider the social, technical, and cognitive aspects of OSS development. We describe our methodology in detail, and discuss its implications for future research on distributed collective practices.

description: In situ optical absorption spectroscopy was used to study the generation of E' centres in amorphous SiO_2 occurring by photo-induced breaking of Si-H groups under 4.7eV pulsed laser radiation. The dependence from laser intensity of the defect generation rate is consistent with a two-photon mechanism for Si-H rupture, while the growth and the saturation of the defects are conditioned by their concurrent annealing due to reaction with mobile hydrogen arising from the same precursor. A rate equation is proposed to model the kinetics of the defects and tested on experimental data.
