D-Dimensional Bose Gases And The Lambert W Function, Sree Ram Valluri, J Tanguay, M Gil, D J. Jeffrey Dec 2010

D-Dimensional Bose Gases And The Lambert W Function, Sree Ram Valluri, J Tanguay, M Gil, D J. Jeffrey

Physics and Astronomy Publications

The applications of the Lambert W function (also known as the W function) to D-dimensional Bose gases are presented. We introduce two sets of families of logarithmic transcendental equations that occur frequently in thermodynamics and statistical mechanics and present their solution in terms of the W function. The low temperature T behavior of free ideal Bose gases is considered in three and four dimensions. It is shown that near condensation in four dimensions, the chemical potential μ and pressure P can be expressed in terms of T through the W function. The low T behavior of one- and two-dimensional ideal …

Peroxisome Proliferator-Activated Receptor -Β/Δ, -Γ Agonists And Resveratrol Modulate Hypoxia Induced Changes In Nuclear Receptor Activators Of Muscle Oxidative Metabolism, Timothy R.H. Regnault, Lin Zhao, Jacky S.S. Chiu, Stephanie K. Gottheil, Allison Foran, Siu Pok Yee Dec 2010

Peroxisome Proliferator-Activated Receptor -Β/Δ, -Γ Agonists And Resveratrol Modulate Hypoxia Induced Changes In Nuclear Receptor Activators Of Muscle Oxidative Metabolism, Timothy R.H. Regnault, Lin Zhao, Jacky S.S. Chiu, Stephanie K. Gottheil, Allison Foran, Siu Pok Yee

Paediatrics Publications

PPAR-α, PPAR-β, and PPAR-γ, and RXR in conjunction with PGC-1α and SIRT1, activate oxidative metabolism genes determining insulin sensitivity. In utero, hypoxia is commonly observed in Intrauterine Growth Restriction (IUGR), and reduced insulin sensitivity is often observed in these infants as adults. We sought to investigate how changes in oxygen tension might directly impact muscle PPAR regulation of oxidative genes. Following eight days in culture at 1 oxygen, C2C12 muscle myoblasts displayed a reduction of PGC-1α, PPAR-α, and RXR-α mRNA, as well as CPT-1b and UCP-2 mRNA. SIRT1 and PGC-1α protein was reduced, and PPAR-γ protein increased. The addition of …

Sympathetic Neural Activation: An Ordered Affair, Craig D. Steinback, Aryan Salmanpour, Toni Breskovic, Zeljko Dujic, J. Kevin Shoemaker Dec 2010

Sympathetic Neural Activation: An Ordered Affair, Craig D. Steinback, Aryan Salmanpour, Toni Breskovic, Zeljko Dujic, J. Kevin Shoemaker

Paediatrics Publications

Is there an ordered pattern in the recruitment of postganglionic sympathetic neurones? Using new multi-unit action potential detection and analysis techniques we sought to determine whether the activation of sympathetic vasomotor neurones during stress is governed by the size principle of recruitment. Multi-unit postganglionic sympathetic activity (fibular nerve) was collected from five male subjects at rest and during periods of elevated sympathetic stress (end-inspiratory apnoeas; 178 ± 37 s(mean ± S.D.)). Compared to baseline (0.24 ± 0.04 V), periods of elevated stress resulted in augmented sympathetic burst size (1.34 ± 0.38 V, P < 0.05). Increased burst size was directly related to both the number of action potentials within a multi-unit burst of postganglionic sympathetic activity (r= 0.88 ± 0.04, P < 0.001 in all subjects), and the amplitude of detected action potentials (r= 0.88 ± 0.06, P < 0.001 in all subjects). The recruitment of larger, otherwise silent, neurons accounted for approximately 74% of the increase in detected action potentials across burst sizes. Further, action potential conduction velocities (inverse of latencies) were increased as a function of action potential size (R2= 0.936, P= 0.001). As axon diameter is positively correlated with action potential size and conduction velocity, these data suggest that the principle of ordered recruitment based on neuronal size applies to postganglionic sympathetic vasomotor neurones. This information may be pertinent to our understanding of reflex-specific recruitment strategies in postganglionic sympathetic nerves, patterns of vasomotor control during stress, and the malleability of sympathetic neuronal properties and recruitment in health and disease.The sympathetic nervous system is an important controller of blood pressure and blood flow to critical tissues and organs. In other neural systems (e.g. the skeletal motor system) there is a well understood pattern of neural recruitment during activation. Alternatively, our understanding of how sympathetic neurones are coordinated during stress is limited. We demonstrate that during stress otherwise silent sympathetic neurones are activated in an order based on neuronal size (from smallest to largest). This recruitment pattern is similar to what is known in other neural systems. This information has important implications for how blood pressure and blood flow are controlled, and the malleability of sympathetic activation in health and disease. © 2010 The Authors.

ObjectiveS: Research implicates the A1 allele of the dopamine D2 receptor gene (DRD2) Taq1A polymorphism in the development of depression and anxiety. Furthermore, recent papers suggest that children with A1 allele of this gene may receive less positive parenting, and that the effects of this gene on child symptoms may be moderated by parenting. We sought to replicate and extend these findings using behavioral measures in a nonclinical sample of young children. Methods: In a sample of 473 preschool-aged children and their mothers, structured clinical interview measures and maternal reports of child symptoms were collected, and standardized observations of parent-child …

Β-Cell-Specific Pyruvate Dehydrogenase Deficiency Impairs Glucose-Stimulated Insulin Secretion, Malathi Srinivasan, Cheol S. Choi, Pushpankur Ghoshal, Lioudmila Pliss, Jignesh D. Pandya, David Hill, Gary Cline, Mulchand S. Patel

Paediatrics Publications

Glucose-stimulated insulin secretion (GSIS) by β-cells requires the generation of ATP from oxidation of pyruvate as well as generation of coupling factors involving three different pyruvate cycling shuttles. The roles of several key enzymes involved in pyruvate cycling in β-cells have been documented using isolated islets and β-cell clonal lines. To investigate the role of the pyruvate dehydrogenase (PDH) complex (PDC) in GSIS, a murine model of β-cell-specific PDH deficiency (β-PDHKO) was created. Pancreatic insulin content was decreased in 1-day-old β-PDHKO male pups and adult male mice. The plasma insulin levels were decreased and blood glucose levels increased in β-PDHKO …

Cancellation Of Indigenous Australians From The Apprenticeship Training Contract, John Mangan, Bernard Trendle Dec 2010

Cancellation Of Indigenous Australians From The Apprenticeship Training Contract, John Mangan, Bernard Trendle

Aboriginal Policy Research Consortium International (APRCi)

The vocational education and training (VET) sector is a major pathway to postschool education for indigenous students, yet questions are being raised about the capacity of the VET system to provide successful outcomes for the indigenous apprentices and trainees it attracts. Within a system plagued by high cancellation rates in general, indigenous apprentices appear to do particularly badly. This paper combines data from an administrative database on apprenticeship with income data from the 2001 Census of Population and Housing to provide an analysis of attrition rates for apprenticeship training contracts in Queensland, asking: Are cancellation rates for indigenous students significantly …

Prospective Evaluation Of A Cognitive Vulnerability-Stress Model For Depression: The Interaction Of Schema Self-Structures And Negative Life Events., Pamela M Seeds, David J A Dozois Dec 2010

Prospective Evaluation Of A Cognitive Vulnerability-Stress Model For Depression: The Interaction Of Schema Self-Structures And Negative Life Events., Pamela M Seeds, David J A Dozois

Psychology Publications

This study tested the diathesis-stress component of Beck's (1967) cognitive theory of depression. Initially, participants completed measures assessing cognitive organization of the self-schema and depressive symptoms. One year later, participants completed measures assessing cognitive organization of the self-schema, depressive symptoms, and negative life events. Hierarchical multiple regression analyses, controlling for initial depression, indicated that more tightly interconnected negative content was associated with greater elevations in depressive symptoms following the occurrence of life events. More diffusely interconnected positive content for interpersonal self-referent information also interacted with life events to predict depressive symptoms. Cognitive organization dimensions showed moderate to high stability across …

Exploring Relationships Between Racism, Housing And Child Illness In Remote Indigenous Communities, Naomi Priest, Yin Paradies, Matthew Stevens, Ross Bailie Nov 2010

Exploring Relationships Between Racism, Housing And Child Illness In Remote Indigenous Communities, Naomi Priest, Yin Paradies, Matthew Stevens, Ross Bailie

Aboriginal Policy Research Consortium International (APRCi)

Background Although racism is increasingly acknowledged as a determinant of health, few studies have examined the relationship between racism, housing and child health outcomes. Methods Cross-sectional data from the Housing Improvement and Child Health study collected in ten remote indigenous communities in the Northern Territory, Australia were analysed using hierarchical logistic regression. Carer and householder self-reported racism was measured using a single item and child illness was measured using a carer report of common childhood illnesses. A range of confounders, moderators and mediators were considered, including socio-demographic and household composition, psychosocial measures for carers and householders, community environment, and health-related …

The Carter Constant For Inclined Orbits About A Massive Kerr Black Hole: I. Circular Orbits, Peter G. Komorowski, Sree Ram Valluri, Martin Houde Nov 2010

The Carter Constant For Inclined Orbits About A Massive Kerr Black Hole: I. Circular Orbits, Peter G. Komorowski, Sree Ram Valluri, Martin Houde

Physics and Astronomy Publications

In an extreme binary black hole system, an orbit will increase its angle of inclination (ι) as it evolves in Kerr spacetime. We focus our attention on the behaviour of the Carter constant (Q) for near-polar orbits, and develop an analysis that is independent of and complements radiation-reactionmodels. For a Schwarzschild black hole, the polar orbits represent the abutment between the prograde and retrograde orbits at whichQis at its maximum value for given values of the latus rectum (˜l ) and the eccentricity (e). The introduction of spin (S˜ = |J|/M2) to themassive black hole causes this boundary, or abutment, …

Role Of Alpha 7 Nicotinic Acetylcholine Receptor In Calcium Signaling Induced By Prion Protein Interaction With Stress-Inducible Protein 1, Flavio H. Beraldo, Camila P. Arantes, Tiago G. Santos, Nicolle G. T. Queiroz, Kirk Young, Jane R. Rylett, Regina P. Markus, Marco A. M. Prado, Vilma R. Martins

Anatomy and Cell Biology Publications

The prion protein (PrP(C)) is a conserved glycosylphosphatidyl-inositol-anchored cell surface protein expressed by neurons and other cells. Stress-inducible protein 1 (STI1) binds PrP(C) extracellularly, and this activated signaling complex promotes neuronal differentiation and neuroprotection via the extracellular signal-regulated kinase 1 and 2 (ERK1/2) and cAMP-dependent protein kinase 1 (PKA) pathways. However, the mechanism by which the PrPC-STI1 interaction transduces extracellular signals to the intracellular environment is unknown. We found that in hippocampal neurons, STI1-PrP(C) engagement induces an increase in intracellular Ca(2+) levels. This effect was not detected in PrP(C)-null neurons or wild-type neurons treated with an STI1 mutant unable to …

Failing To Ignore: Paradoxical Neural Effects Of Perceptual Load On Early Attentional Selection In Normal Aging, Taylor W. Schmitz, Frederick H.T. Cheng, Eve De Rosa Nov 2010

Failing To Ignore: Paradoxical Neural Effects Of Perceptual Load On Early Attentional Selection In Normal Aging, Taylor W. Schmitz, Frederick H.T. Cheng, Eve De Rosa

Brain and Mind Institute Researchers' Publications

We examined visual selective attention under perceptual load - simultaneous presentation of task-relevant and -irrelevant information - in healthy young and older adult human participants to determine whether age differences are observable at early stages of selection in the visual cortices. Participants viewed 50/50 superimposed face/place images and judged whether the faces were male or female, rendering places perceptible but task-irrelevant. Each stimulus was repeated, allowing us to index dynamic stimulus-driven competition from places. Consistent with intact early selection in young adults, we observed no adaptation to unattended places in parahippocampal place area (PPA) and significant adaptation to attended faces …

Enhancing Use Case Points Estimation Method Using Soft Computing Techniques, Ali Bou Nassif, Luiz Fernando Capretz, Nfa-Estimation Nov 2010

Enhancing Use Case Points Estimation Method Using Soft Computing Techniques, Ali Bou Nassif, Luiz Fernando Capretz, Nfa-Estimation

Electrical and Computer Engineering Publications

Software estimation is a crucial task in software engineering. Software estimation encompasses cost, effort, schedule, and size. The importance of software estimation becomes critical in the early stages of the software life cycle when the details of software have not been revealed yet. Several commercial and non-commercial tools exist to estimate software in the early stages. Most software effort estimation methods require software size as one of the important metric inputs and consequently, software size estimation in the early stages becomes essential. One of the approaches that has been used for about two decades in the early size and effort …

From Music Tracks To Google Maps: Who Owns Computer-Generated Works?, Mark Perry, Thomas Margoni

Law Publications

Increasingly the digital content used in everyday life has little or no human intervention in its creation. Typically, when such content is delivered to consumers it comes with attached claims of copyright. However, depending on the jurisdiction, approaches to ownership of computer-generated works vary from legislated to uncertain. In this paper we look at the various approaches taken by the common law, such as in Canada, and the legislative approach taken in the United Kingdom. The options for how computer-generated works may be treated and suggestions for their best placement in copyright are discussed.

The Role Of Brain-Derived Neurotrophic Factor Genotype, Parental Depression, And Relationship Discord In Predicting Early-Emerging Negative Emotionality, Elizabeth P. Hayden, Daniel N. Klein, Lea R. Dougherty, Thomas M. Olino, Margaret W. Dyson, C. Durbin, Haroon I. Sheikh, Shiva M. Singh Nov 2010

The Role Of Brain-Derived Neurotrophic Factor Genotype, Parental Depression, And Relationship Discord In Predicting Early-Emerging Negative Emotionality, Elizabeth P. Hayden, Daniel N. Klein, Lea R. Dougherty, Thomas M. Olino, Margaret W. Dyson, C. Durbin, Haroon I. Sheikh, Shiva M. Singh

Paediatrics Publications

The brain-derived neurotrophic factor (BDNF) gene is a plausible candidate for early-emerging negative emotionality (NE), and evidence suggests that the effects of this gene may be especially salient in the context of familial risk for child maladjustment. We therefore examined whether the single-nucleotide polymorphism producing a valine-to-methionine substitution at codon 66 (val66met) of the BDNF gene was associated with childhood NE, in the context of parental depression and relationship discord. A sample of 413 three-year-old children was assessed for NE using standardized laboratory measures. The children's parents completed clinical interviews as well as a measure of marital satisfaction. Children with …

Adjuvant Immunotherapy Increases Β Cell Regenerative Factor Reg2 In The Pancreas Of Diabetic Mice, Katrina Huszarik, Benjamin Wright, Christina Keller, Enayat Nikoopour, Olga Krougly, Edwin Lee-Chan, Hui Yu Qin, Mark J. Cameron

Paediatrics Publications

Insulin-producing β cells can partially regenerate in adult pancreatic tissues, both in human and animal models of type 1 diabetes (T1D). Previous studies have shown that treatment with mycobacterial adjuvants such as CFA and bacillus Calmette-Guérin prevents induction and recurrence of T1D in NOD mice with partial recovery of β cell mass. In this study, we investigated factors involved in the regeneration of β cells in the pancreas of NOD mice during diabetes development and after treatment with adjuvants. The Regeneration (Reg) gene family is known to be involved in regeneration of various tissues including β cells. Reg2 expression was …

Digital Prosumption And Alienation, Edward Comor Nov 2010

Digital Prosumption And Alienation, Edward Comor

FIMS Publications

Since the hybrid producer-consumer – the prosumer – was conceptualized three decades ago, prosumption has been embraced by both mainstream and progressive analysts. With digital technologies enabling more people to engage in an array of online prosumption activities, one shared claim is particularly striking: the empowering and humanizing implications of prosumption will mark the end of human alienation. In this paper, I assess this extraordinary prediction by, first, establishing that the core of Marx’s conceptualization of alienation is capital’s dominance over human relations, compelling people to become mere tools of the production process. Second, I assess both general and specific …

Another Look At Bill C-32 And The Access Copyright Tariff: Still Double Trouble For Higher Education, Samuel E. Trosow Oct 2010

Another Look At Bill C-32 And The Access Copyright Tariff: Still Double Trouble For Higher Education, Samuel E. Trosow

FIMS Presentations

Earlier this year, the government tabled Bill C-32, proposed amendments to the Copyright Act. Following a consultation process, the Bill is widely recognized as more reasonable than its predecessor, Bill C-61. On the positive side, the bill would expand fair dealing to explicitly include "education". On the other hand, the digital locks provisions of the Bill are fundamentally flawed and override many existing and proposed users rights. Also this year, Access Copyright filed a proposed tariff for the post-secondary education sector with the Copyright Board. The proposal, which includes a drastic increase in costs as well as numerous new reporting …

A Systematic Review On The Diagnosis Of Pediatric Bacterial Pneumonia: When Gold Is Bronze, Tim Lynch, Liza Bialy, James D. Kellner, Martin H. Osmond, Terry P. Klassen, Tamara Durec, Robin Leicht, David W. Johnson Oct 2010

A Systematic Review On The Diagnosis Of Pediatric Bacterial Pneumonia: When Gold Is Bronze, Tim Lynch, Liza Bialy, James D. Kellner, Martin H. Osmond, Terry P. Klassen, Tamara Durec, Robin Leicht, David W. Johnson

Paediatrics Publications

Background: In developing countries, pneumonia is one of the leading causes of death in children under five years of age and hence timely and accurate diagnosis is critical. In North America, pneumonia is also a common source of childhood morbidity and occasionally mortality. Clinicians traditionally have used the chest radiograph as the gold standard in the diagnosis of pneumonia, but they are becoming increasingly aware that it is not ideal. Numerous studies have shown that chest radiography findings lack precision in defining the etiology of childhood pneumonia. There is no single test that reliably distinguishes bacterial from non-bacterial causes. These …
