description: We present a new class of non-singular string cosmologies in d space-time dimensions. At very early times, τ<< τ_c, the Universe is described by a flat σ-model metric, a constant maximal temperature T_c and super-weak string interactions, g_str << 1. During the evolution, the metric remains flat up to τ_c, while the string coupling grows and reaches a critical value g*_str at τ_c. This phase is characterized by a uniform temporal distribution of spacelike branes. At later times, τ> τ_c, the Universe enters in a new phase of expansion, with radiation. The string coupling decreases due to the dilaton motion and asymptotes to a constant for τ>> τ_c. Throughout the evolution, the string coupling remains smaller than g*_str. In the Einstein frame, the cosmologies describe bouncing Universes, where two distinct phases are connected at τ_c. In the initial contracting phase, the evolution of the scale factor is identical to that of a negatively curved Universe filled with radiation. At later times, the Universe enters in an expanding thermal phase with a running dilaton. Explicit examples are presented in a large class of thermal (4,0) type II superstring vacua, with non-trivial "gravito-magnetic" fluxes.

description: Khoa is one of the most important bases for preparing indigenous sweets. The production of khoa was 4.9% in the year 1966 while only 8.7% of milk was being used for the production of products out of the total dairy production. However, the total khoa production is over 300 million kg valued at 300 crores at the present rate. Khoa is mostly produced in northern and western part of our country. The maximum amount of khoa is produced by Uttar-Pradesh, nearly 36.0% of the total production. Even in U.P. the major khoa producing cities and their surrounding area are Meerut, Muradabad, Muzaffarnagar, Aligarh, Hathars, Etawah, Kanpur etc.

Retrieving the three-dimensional matter power spectrum and galaxy biasing parameters from lensing tomography

description: With the availability of galaxy distance indicators in weak lensing surveys, lensing tomography can be harnessed to constrain the three-dimensional (3D) matter power spectrum over a range of redshift and physical scale. By combining galaxy-galaxy lensing and galaxy clustering, this can be extended to probe the 3D galaxy-matter and galaxy-galaxy power spectrum or, alternatively, galaxy biasing parameters. To achieve this aim, this paper introduces and discusses minimum variance estimators and a more general Bayesian approach to statistically invert a set of noisy tomography 2-point correlation functions, measured within a confined opening angle. Both methods are constructed such that they probe deviations of the power spectrum from a fiducial power spectrum, thereby enabling both a direct comparison of theory and data, and in principle the identification of the physical scale and redshift of deviations. By devising a new Monte Carlo technique, we quantify the measurement noise in the correlators for a fiducial survey, and test the performance of the inversion techniques. We conclude that a shear tomography analysis of near future weak lensing surveys promises fruitful insights into the effect of baryons on the nonlinear matter power spectrum at z

description: We specify for a general correlation scenario a particular type of a local quasi hidden variable (LqHV) model [J. Math. Phys. 53 (2012), 022201] -- a deterministic LqHV model, where all joint probability distributions of a correlation scenario are simulated via a single measure space with a normalized bounded real-valued measure not necessarily positive and random variables, each depending only on a setting of the corresponding measurement at the corresponding site. We prove that an arbitrary multipartite correlation scenario admits a deterministic LqHV model if and only if all its joint probability distributions satisfy the consistency condition constituting the general nonsignaling condition formulated in [J. Phys. A: Math. Theor. 41 (2008), 445303]. This mathematical result specifies a new probability model that has the measure-theoretic structure resembling the structure of the classical probability model but incorporates the latter only as a particular case. The local version of this quasi classical probability model covers the probabilistic description of every nonsignaling correlation scenario, in particular, each correlation scenario on an multipartite quantum state.

Battles staged by : the development and organization of stage combat in Canada
Creators: name: Harrison, Nicholas John
Publisher: name: University of British Columbia
Year: 2012

description: This dissertation traces the history and development of stage combat in Canada. The Canadian Theatre Agreement of 2002 recognized fight directors as professional theatre artists for the first time. However, the first recorded professional fight director in Canada was Douglas Campbell at the Stratford Festival in 1953. The fight director has been part of a long theatrical tradition that involves both artistic interpretation of dramatic texts and practical skills. To date there has not been a thorough investigation of the history of the fight director in Canada. Chapter One defines the role and function of the fight director and introduces the people interviewed as part of my research. In Chapter Two explores the origins of modern stage combat. Chapter Three concerns the roles that Douglas Campbell and Patrick Crean played in the establishment of professional stage combat in Canada through their involvement with the Stratford Festival. Chapters Four and Five explore the emergence of the two major Canadian fight associations and the training syllabi they created to properly train actor combatants. Through a series of interviews with professional Canadian fight directors, Chapter Six focuses on the role of the fight director as artist, dramaturg, instructor and choreographer, and analyzes their experiences staging fights for various Canadian productions of Hamlet. Chapter Seven explains the varying methods of fight notation instrumental in archiving a fight director's work for reference. Chapter Eight summarizes the role and function of the fight director in modern Canadian theatre. These elements are placed in context through personal interviews, newspaper articles, existing scholarship on stage combat and fencing, as well as current training methodologies used by Fight Directors Canada.

description: Although much is known about the virus believed by most experts to be the cause of the acquired immunodeficiency syndrome and about its pathogenic actions, major areas of ignorance remain. Among these are the reasons for the varying time between infection with human immunodeficiency virus and development of acquired imunodeficiency syndrome, the relationship between neurologic and medical aspects of the disease, the time course of neuropsychological findings, and the prevalence of psychiatric morbidity. We assessed 124 homosexual men who were positive for human immunodeficiency virus and 84 who were negative for the virus. In this article we describe the study design, method of recruitment, and medical and demographic characteristics of the cohort, which will be followed up for 5 years.

description: Recently, a tentative 130 GeV $γ$-ray line signal was identified by quite a few groups. If correct it would constitute a ``smoking gun'' for dark matter annihilations. Interestingly, the spectra of the cosmic ray electrons detected by PAMELA and Fermi-LAT both show tiny wiggle-like structure at $\sim 100$ GeV, which might indicate a weak signal of the annihilation of $\sim 130$ GeV dark matter particles into electrons/positrons with a velocity-weighted cross section $\langleσv\rangle_{\rm χχ\rightarrow e^{+}e^{-}} \sim 4\times10^{-26}~{\rm cm^{3}~s^{-1}}$. The prospect of identifying such a potential weak dark-matter-annihilation electron and/or positron component by AMS-02, a mission to measure the high energy cosmic ray spectra with unprecedented accuracy, is investigated.

description: The onset of superconductivity at the transition temperature is marked by the onset of order, which is characterized by an energy gap. Most models of the iron-based superconductors find a sign-changing (s\pm) order parameter [1-6], with the physical implication that pairing is driven by spin fluctuations. Recent work, however, has indicated that LiFeAs has a simple isotropic order parameter [7-9] and spin fluctuations are not necessary [7,10], contrary to the models [1-6]. The strength of the spin fluctuations has been controversial [11,12], meaning that the mechanism of superconductivity cannot as yet be determined. Here we report the momentum dependence of the superconducting energy gap, where we find an anisotropy that rules out coupling through spin fluctuations and the sign change. The results instead suggest that orbital fluctuations assisted by phonons [13,14] are the best explanation for superconductivity.

description: We describe how the Hardy-Ramanujan-Rademacher formula can be implemented to allow the partition function $p(n)$ to be computed with softly optimal complexity $O(n^{1/2+o(1)})$ and very little overhead. A new implementation based on these techniques achieves speedups in excess of a factor 500 over previously published software and has been used by the author to calculate $p(10^{19})$, an exponent twice as large as in previously reported computations. We also investigate performance for multi-evaluation of $p(n)$, where our implementation of the Hardy-Ramanujan-Rademacher formula becomes superior to power series methods on far denser sets of indices than previous implementations. As an application, we determine over 22 billion new congruences for the partition function, extending Weaver's tabulation of 76,065 congruences.

Occupations

description: We previously reported an inverse relation between parietal cerebral blood flow and years of education in Alzheimer's disease (AD) patients matched for clinical severity. This suggested that the clinical manifestation of advancing AD pathology is delayed in patients with higher educational attainment. Other aspects of life experience may also provide a reserve against the clinical expression of AD. To test this hypothesis, we classified the primary lifetime occupations of 51 AD patients using the Dictionary of Occupational Titles, published by the US Department of Labor, and derived six factor scores describing intellectual, interpersonal, and physical job demands. Regional cerebral blood flow was measured using the xenon-133 inhalation method. After controlling for age, clinical dementia severity, and education, there was less relative perfusion in the parietal region in subjects whose occupations were associated with higher interpersonal skills and physical demands factor scores. We conclude that independent of education, aspects of occupational experience may provide a reserve that delays the clinical manifestation of AD.

description: OBJECTIVE: To examine the effects of caregiver and patient characteristics on caregivers' medical care use and cost. METHODS: One hundred forty-seven caregiver/patient dyads were followed annually for 6 years in three academic Alzheimer's disease centers in the United States. Logistic, negative binomial, and generalized linear mixed models were used to examine overall effects of caregiver/patient characteristics on caregivers' hospitalizations, doctor visits, outpatient tests and procedures, and prescription and over-the-counter medications. RESULTS: Patients' comorbid conditions and dependence were associated with increased health-care use and costs of caregivers. Increases in caregiver depressive symptoms are associated with increases in multiple domains of caregivers' health-care use and costs. DISCUSSION: Findings suggest expanding our focus on dementia patients to include family caregivers to obtain a fuller picture of effects of caregiving. Primary care providers should integrate caregivers' needs in health-care planning and delivery. Clinical interventions that treat patients and caregivers as a whole will likely achieve the greatest beneficial effects.

description: Photon structure functions in supersymmetric QCD are investigated in terms of the parton model where squark contributions are evaluated. We calculate the eight virtual photon structure functions by taking the discontinuity of the squark massive one-loop diagrams of the photon-photon forward amplitude. The model-independent positivity constraints derived from the Cauchy-Schwarz inequalities are satisfied by the squark parton model calculation and actually the two equality relations hold for the squark contribution. We also show that our polarized photon structure function $g_1^γ$ for the real photon leads to the vanishing 1st moment sum rule, and the constraint $|g_1^γ|\leq F_1^γ$ is satisfied by the real photon. We also discuss a squark signature in the structure function $W_{TT}^τ$.

From these we can construct new superintegrable models. One realisation is in terms of a staggered isotropic XY spin chain. Further we investigate the importance of the algebra for the existence of mutually commuting charges. This leads us to a natural generalisation of the boost-operator, which generates the charges.

Las muestras incluyen 87 lagunas en el páramo, la región interandina, la Amazonía, la costa y Galápagos.  Para varias lagunas tenemos muestras de diferentes años.  La mayoría fueron muestreadas solamente una vez.   Muestreamos las lagunas con una red de plancton tanto en el centro de la laguna, como en varios microhábitats de las orillas.  La mayoría de las especies encontradas son diatomeas, aunque no son generalmente las especies dominantes.  El análisis de componentes principales indica que las diferentes regiones del país tienen distintas comunidades de fitoplancton, que reflejan las diferentes condiciones fisicoquímicas de las lagunas.  Hay correlación entre el número de especies de las lagunas y su área, en particular el área de la zona litoral.  En los 40 años de estudios notamos cambios en las comunidades de fitoplancton de algunas lagunas.  Estos cambios parecen ligados a la influencia humana y al cambio climático.  En las lagunas eutróficas como Yambo, Yahuarcocha y Limoncocha dominan las cianobacterias.  Encontramos una invasión reciente de la cianobacteria tóxica Cylindrospermopsis raciborskii en algunas lagunas de la Sierra, de la Costa y del Oriente. Esto puede ser el resultado del incremento en el Ecuador del uso de herbicidas que contienen glifosato, ya que Cylindrospermopsis lo utiliza como nutriente tanto para P y para N y el glifosato mata a las algas eucarióticas.

description: The objective of this study was to describe the occurrence of HIV dementia and neuropsychological testing abnormalities in a new cohort of HIV-seropositive individuals at high risk for HIV dementia and to compare these results to a cohort before the advent of highly active antiretroviral therapy (HAART). HAART has been associated with improvements in cognitive performance in some HIV-infected patients. However, it is uncertain whether HAART has changed the frequency of specific neurocognitive abnormalities. Baseline data from 272 HIV-seropositive subjects in the Dana cohort recruited from January, 1994, to December, 1995, and 251 HIV-seropositive subjects in the Northeastern AIDS Dementia Consortium (NEAD) cohort recruited from April, 1998, to August, 1999, were compared. Participants in both cohorts received nearly identical assessments. After adjusting for differences in age, education, gender, race, and CD4 count between the two cohorts, there were no differences in the occurrence of HIV dementia or abnormalities either 1 SD or 2 SDs below established norms for any of the neuropsychological tests. Even though HAART has reduced the incidence of HIV dementia, HIV-associated cognitive impairment continues to be a major clinical problem among individuals with advanced infection.

description: This thesis utilises a research framework based on a double diamond model to explore design challenges in revitalising post-industrial sites. Specifically, it investigates the potential of Human-Centred Emotional Design (HCED) theory to enhance the visitor experience and contribute to the regeneration sites. To achieve the research objectives, this thesis conducts an extensive literature review encompassing existing research on urban regeneration, post-industrial transformation, and relevant theories regarding HCED and design approaches. This review aims to define the scope of HCED in this study, highlight current issues in post-industrial regeneration projects, emphasise complexities associated with converting former industrial sites, and identify potential future trends in urban regeneration efforts. Based on insights from the literature review, this thesis proposes a hypothesis that HCED theory can facilitate the regeneration of post-industrial sites at the visceral, behavioural, and reflective design levels. To test this hypothesis, the study employs diverse research methods, including fieldwork-based case studies, to gain comprehensive insights into various types of regeneration projects across diverse cultural contexts. Additionally, participatory design methods, such as focus groups, questionnaires, interviews, and analysis of digital footprints, are used to gather insights and feedback from stakeholders representing different backgrounds.The findings from the case studies and stakeholder engagement inform the development of a design framework rooted in HCED theory. This framework is further validated through the creation of a conceptual design and a comparative analysis with the existing design of Albert Dock. Both designs are recreated in virtual reality (VR) to facilitate participant comparison. Galvanic Skin Response (GSR) techniques and self-report questionnaires are employed to collect participants' emotional responses and assess their preferences. The experimental results indicate that participants generally show a greater inclination towards the conceptual design based on HCED theory, finding it more engaging across all three design levels. Consequently, it can be concluded that the HCED-based design framework proposed in this study is effective and has the potential to significantly enhance the visitor experience in post-industrial regeneration projects. This design-oriented research project addresses the emotional aspects of urban regeneration design, particularly in relation to the redevelopment of post-industrial sites. It offers a standardised, principled, and interdisciplinary design solution for the field of urban regeneration. Furthermore, the theoretical contributions of this thesis promote a comprehensive understanding of how post-industrial sites can be transformed into vibrant, habitable urban spaces that cater to the emotional and psychological needs of visitors.

description: The walk distances in graphs have no direct interpretation in terms of walk weights, since they are introduced via the \emph{logarithms} of walk weights. Only in the limiting cases where the logarithms vanish such representations follow straightforwardly. The interpretation proposed in this paper rests on the identity $\ln\det B=\tr\ln B$ applied to the cofactors of the matrix $I-tA,$ where $A$ is the weighted adjacency matrix of a weighted multigraph and $t$ is a sufficiently small positive parameter. In addition, this interpretation is based on the power series expansion of the logarithm of a matrix. Kasteleyn (1967) was probably the first to apply the foregoing approach to expanding the determinant of $I-A$. We show that using a certain linear transformation the same approach can be extended to the cofactors of $I-tA,$ which provides a topological interpretation of the walk distances.

Spilotes pullatus

description: Spilotes pullatus (Linnaeus, 1758) Records. Table 2. The Yellow Rat Snake was easily identified in the field by its size (TL = 230.9 cm ± 46.9; n = 2), shape, and color pattern, and through comparisons to collected specimens (e.g. ZUFMS-REP02134). The body was slender and laterally compressed with head quite distinct from the neck. Dorsally, the body was black with yellow spots, which formed crossbands, and on the all-black tail, the yellow banding was absent. The tip of the snout was yellow. The head shields were black, with a combination of yellow and black crossbands and black sutures between shields. Ventrally, specimens were yellow, with irregular black crossbands (Fig. 8).

description: We present results for W-boson production at large transverse momentum at LHC and Tevatron energies. We calculate complete next-to-leading-order (NLO) QCD corrections and higher-order soft-gluon corrections to the differential cross section. The soft-gluon contributions are resummed at next-to-next-to-leading-logarithm (NNLL) accuracy via the two-loop soft anomalous dimensions. Both NLO and approximate next-to-next-to-leading-order (NNLO) p_T distributions are presented. Our numerical results are in good agreement with recent data from the LHC.

description: Erythrolamprus aesculapii (Linnaeus, 1758) Records. Table 2. The False Coral Snake was identified by its size (TL = 89.5 cm ± 6.4; n = 2) and color pattern of alternating red, black, and white rings. The arrangement of these rings showed a pair of black bands with a medial white band, the head was black with a white band posterior to the eyes, and the dorsal color patterns extended onto the belly (Fig. 9). We used collected specimens to help with identifications (e.g. ZUFMS-REP01385, REP01569, REP01629, REP01899).

description: Objective: To determine whether the rate of decline in performance on a memory test is more rapid in AD patients with higher versus lower educational and occupational attainment. Background: Epidemiologic and imaging studies have suggested that, given comparable clinical severity of dementia, AD pathology is more advanced in patients with higher educational and occupational attainment. Because educational and occupational attainment should not influence the progression of AD pathology, and because severe AD pathology will eventually produce a mortality-causing condition, people with higher attainment might experience clinical AD for a shorter time and have a more rapid clinical progression. Methods: A total of 177 AD patients were tested yearly for up to four study visits with the Selective Reminding Test (a memory test). Analysis of prospective change in the total recall score was performed by applying generalized estimating equations to regression analyses with repeated measures. Results: At the initial visit, scores were comparable in the high- and low-education and the high- and low-occupation groups. Overall, memory scores declined by approximately 1 point yearly (p < 0.01). There was a more rapid decline in memory scores in patients with higher educational (p < 0.057) and higher occupational attainment (p < 0.02). The authors then stratified patients based on their initial memory scores. The more rapid decline in memory scores associated with higher educational and occupational attainment was noted only in the group with low initial scores (p < 0.05 for both). The full group and stratified group analyses were also repeated controlling for other potentially relevant variables including age, gender, race, ethnicity, and the presence of extrapyramidal signs, stroke, or at least one apolipoprotein E-ε4 allele. The results remained unchanged. Conclusions: Memory declined more rapidly in AD patients with higher educational and occupational attainment. This adds support to the idea that the discontinuity between the degree of AD pathology and the observed clinical severity of AD is mediated through some form of reserve.
Social capital, institutions, and economic development in China
Creators: name: Wang, Shun
Publisher: name: University of British Columbia

description: This thesis investigates the impact of social capital and institutions on economic development in China. Specifically, Chapters Two and Three address issues regarding social capital and cooperation, and Chapter Four studies the effect of a specific institution on economic status. In Chapter Two, I study whether social capital has an effect on household decisions to participate in Rotating Labor Associations (ROLAs) in rural China. I find that households in communities with higher levels of social capital are more likely to participate in ROLAs using household data collected from the Gansu province in China. The presence of village temple prior to 1949 is employed as an instrument for social capital. Numerous falsification exercises are performed to evaluate the efficacy of the instrumental variables approach. In Chapter Three (joint with Kathy Baylis and Yazhen Gong), we compare the effect of bridging versus bonding social capital on the management of a common pool resource. We develop a theoretical model and show that bonding social capital increases vulnerability to social sanction, while by giving communities an outside option, bridging social capital can reduce people’s vulnerability to social sanction, and reducing the enforcement capability of the community. However, bridging social might decrease people’s consumption by providing financial support to those who have few options to self-insure against risk. We then show that the empirical analysis using household level data on firewood collection from the Yunnan province in China supports the theoretical findings. In Chapter Four, I study the long-term impact of class identity (chengfen) on individuals’ income and households’ wealth in urban China. The Chinese government launched movements to make income and consumption in cities substantially homogeneous and assigned an inheritable class identity to each family in the 1950s. The government then implemented class-based discriminatory policies against the rich and middle class until 1978. This chapter shows that individuals with poor class origins have significantly lower income and family assets per capita than those from the rich class in 2002, however individuals with revolutionary background and Chinese Community Party (CCP) members from the poor class do not have lower income than those from the rich.

description: A comparison between existing measurements and calculations of the scalar spin-spin interaction (J-coupling) in deuterated molecular hydrogen (HD) yields stringent constraints on anomalous spin-dependent potentials between nucleons at the atomic scale (${\rm \sim 1 Å}$). The dimensionless coupling constant $g_P^pg_P^{N}/4π$ associated with exchange of pseudoscalar (axion-like) bosons between nucleons is constrained to be less than $5\times 10^{-7}$ for boson masses in the range of $5 {\rm keV}$. This represents improvement by a factor of about 100 over constraints placed by measurements of the dipole-dipole interaction in molecular ${\rm H_2}$. The dimensionless coupling constant $g_A^pg_A^N/4 π$ associated with exchange of a heretofore undiscovered axial-vector boson between nucleons is constrained to be $g_A^pg_A^N/4 π< 2 \times 10^{-19}$ for bosons of mass $\lesssim 1000 {\rm eV}$, improving constraints at this distance scale by a factor of 100 for proton-proton couplings and more than 8 orders of magnitude for neutron-proton couplings. This limit is also a factor of 100 more stringent than recent constraints obtained for axial-vector couplings between electrons and nucleons obtained from comparison of measurements and calculations of hyperfine structure.

Size matters: the non-universal density profile of subhaloes in SPH simulations and implications for the Milky Way's dSphs

description: We use dark matter only and full hydrodynamical Constrained Local UniversE Simulations (CLUES) of the formation of the Local Group to study the density profile of subhaloes of the simulated Milky Way and Andromeda galaxies. We show that the Einasto model provides the best description of the subhaloes' density profile, as opposed to the more commonly used NFW profile or any generalisation of it. We further find that the Einasto shape parameter \nEin\ is strongly correlated with the total subhalo mass, pointing towards the notion of a non-universality of the subhaloes' density profile. We observe that the effect of mass loss due to tidal stripping, in both the dark matter only and the hydrodynamical run, is the reduction of the shape parameter \nEin\ between the infall and the present time. Assuming now that the dSphs of our Galaxy follow the Einasto profile and using the maximum and minimum values of \nEin\ from our hydrodynamical simulation as a gauge, we can improve the observational constraints on the \Rmax-\Vmax\ pairs obtained for the brightest satellite galaxies of the Milky Way. When considering only the subhaloes with $-13.2\lesssim M_V\lesssim-8.8$, i.e. the range of luminosity of the classical dwarfs, we find that all our simulated objects are consistent with the observed dSphs if their haloes follow the Einasto model with $1.6\lesssim n_{\rm E} \lesssim5.3$. The numerically motivated Einasto profile for the observed dSphs will alleviate the recently presented "massive failures" problem.
