Year: 2011
Subjects: subject: High Energy Physics - Experiment (hep-ex)

description: This letter presents a search for singly produced vector-like quarks, Q, coupling to light quarks, q. The search is sensitive to both charged current (CC) and neutral current (NC) processes, p p --> Q q --> W q q' and p p --> Q q --> Z q q' with a leptonic decay of the vector gauge boson. In 1.04/fb of data taken in 2011 by the ATLAS experiment at a center-of-mass energy sqrt(s) = 7 TeV, no evidence of such heavy vector-like quarks is observed above the expected Standard Model background. Limits on the heavy vector-like quark production cross section times branching ratio as a function of mass m_Q are obtained. For a coupling kappa_(qQ) = v/m_Q, where v is the Higgs vacuum expectation value, 95% C.L. lower limits on the mass of a vector-like quark are set at 900 GeV and 760 GeV from CC and NC processes, respectively.

description: In a recent paper of Nandkishore and Senthil [arxiv:1201.5998 (2012)], a concept of orthogonal metal has been introduced to reinterpret the disordered state of slave-spin representation in the Hubbard model as an exotic gapped metallic state. We extend this concept to study the corresponding quantum phase transition in the extended Anderson lattice model. It is found that the disordered state of slave spins in this model is an orbital-selective orthogonal metal, a generalization of the concept of the orthogonal metal in the Hubbard model. Near the quantum critical point the essential behaviors are dominated by a z = 3 critical mode, which is in contrast to the naive expectation in the Hubbard model. The result provides alternative Kondo breakdown mechanism for heavy fermion compounds underlying the physics of the orbital-selective orthogonal metal in the disordered state, which is different from the conventional Kondo breakdown mechanism with the fractionalized Fermi liquid picture. This work is expected to be useful in understanding the quantum criticality happening in some heavy fermion materials and other related strongly correlated systems.

description: The work reported in this thesis explores the relationships between the crystal structure of mixed metal oxides and their electrical properties. This was accomplished by synthesizing phase pure pyrochlore and garnet compositions using the traditional solid state method. The bulk of this work was focused on strontium doped bismuth stannate (SrxBi2-xSn2O7-?) pyrochlores and calcium-tin-gallate (Ca2.65+x+ySn2.65+x-yGa2.70-2xO12-y) garnets. The electrical properties were investigated using variable temperature impedance spectroscopy and equivalent circuit modelling of the data. The crystal structures were studied using a variety of techniques including laboratory powder X-ray diffraction, synchrotron powder X-ray diffraction and neutron powder diffraction. The first study investigated the structure and electrical properties of strontium doped bismuth stannate (SrxBi2-xSn2O7-?) pyrochlores. The polymorphic structures of strontium doped SrxBi2-xSn2O7-? were investigated using combined synchrotron X-ray diffraction and neutron powder diffraction. At room temperature, the orthorhombic ?-phase of Bi2Sn2O6O’ was stabilized with strontium doping levels of x?0.15, and the cubic ?-phase was stabilized with higher doping levels x>0.15. The materials were studied using powder neutron diffraction at 800°C, revealing that all five compositions had adopted the ?-phase. The variable temperature electrical properties were investigated revealing a predominately electronic conductivity. The second study in this work focuses on the ionic conductivity and structure of the calcium-tin-gallate (Ca2.65+x+ySn2.65+x-yGa2.70-2xO12-y) solid solution of garnets. A series of unique compositions were synthesized. The average structure was investigated at room temperature for all nine compositions presented here, while five of the compositions were chosen to be used in a variable temperature neuron diffraction study. The oxide ion conduction pathways were explored in the calcium-tin-gallate (Ca2.65+x+ySn2.65+x-yGa2.70-2xO12-y) garnets using the refined models from the NPD and soft bond valence sum analysis. An EMF transport number measurement on Ca2.80Sn2.80Ga2.40O12 indicated high levels of oxide ion conductivity, as indicated with the values measured being greater than 0.90. Oxygen partial pressure (pO2) stability measurements were attempted on Ca2.65Sn2.65Ga2.70O12 and Ca2.95Sn2.95Ga2.10O12, in both cases indicating a stable conductivity in a pO2 range of 1 atm to 10-4 atm in the ionic conduction region.

description: We propose a formalism for tilings with infinite local complexity (ILC), and especially fusion tilings with ILC. We allow an infinite variety of tile types but require that the space of possible tile types be compact. Examples include solenoids, pinwheel tilings, tilings with fault lines, and tilings with infinitely many tile sizes, shapes, or labels. Special attention is given to tilings where the infinite local complexity comes purely from geometry (shears) or comes purely from combinatorics (labels). We examine spectral properties of the invariant measures and define a new notion of complexity that applies to ILC tilings.

description: Context: Pregnancy is a significant experience in the lives of many people. Its associations with deeply entrenched sociocultural norms and messages about motherhood and femininity are widely known. Despite North American stories of pregnancy being tied to femininity, there are many pregnant people whose experiences do not align with these dominant stories, such as trans and gender diverse people. While the literature on pregnancy includes a handful of studies that have addressed the experiences and/or needs of trans and gender diverse people, there has yet to be a study pertaining to pregnancy among people who express their gender in diverse ways but who have specifically not undertaken gender-affirming hormones or surgery. Goals: The aim of this study was to fill gaps in the literature by gaining rich information about the lives and experiences of gender diverse people who experienced pregnancy. My hope was that the information gathered in conversations with participants would provide guidance to psychologists and other healthcare professionals on how to support gender diverse people during their pregnancies.Methods: Narrative inquiry was the methodological guide for this dissertation. Founded by Clandinin and Connelly (2000), narrative inquiry is the study of experience as story. I engaged in conversations with four participants over the course of 8 months, meeting with them five to eight times. Conversations were focused on stories of pregnancy, gender, and the various life experiences that informed participants’ pregnancy experiences.Results: Narrative accounts were written for each participant in accordance with Clandinin and Connelly’s approach (2000), staying anchored to the three-dimensional narrative inquiry space of temporality, sociality, and place. Across the four narrative accounts five narrative threads were identified: Resisting and enduring dominant stories; the more things change, the more they are the same; languaging our lives; the relationships that fuel us; and our midwifery teams knocked it out of the park.Discussion and Implications: Participant stories and the narrative threads were used to highlight implications for gender-affirming practice, training, policy, and research at micro, meso, and macro levels. The strengths and limitations of this study were also identified.
The Extreme Small Scales: Do Satellite Galaxies Trace Dark Matter?

description: We investigate the radial distribution of galaxies within their host dark matter halos by modeling their small-scale clustering, as measured in the Sloan Digital Sky Survey. Specifically, we model the Jiang et al. (2011) measurements of the galaxy two-point correlation function down to very small projected separations (10 < r < 400 kpc/h), in a wide range of luminosity threshold samples (absolute r-band magnitudes of -18 up to -23). We use a halo occupation distribution (HOD) framework with free parameters that specify both the number and spatial distribution of galaxies within their host dark matter halos. We assume that the first galaxy in each halo lives at the halo center and that additional satellite galaxies follow a radial density profile similar to the dark matter Navarro-Frenk-White (NFW) profile, except that the concentration and inner slope are allowed to vary. We find that in low luminosity samples, satellite galaxies have radial profiles that are consistent with NFW. M_r < -20 and brighter satellite galaxies have radial profiles with significantly steeper inner slopes than NFW (we find inner logarithmic slopes ranging from -1.6 to -2.1, as opposed to -1 for NFW). We define a useful metric of concentration, M_(1/10), which is the fraction of satellite galaxies (or mass) that are enclosed within one tenth of the virial radius of a halo. We find that M_(1/10) for low luminosity satellite galaxies agrees with NFW, whereas for luminous galaxies it is 2.5-4 times higher, demonstrating that these galaxies are substantially more centrally concentrated within their dark matter halos than the dark matter itself. Our results therefore suggest that the processes that govern the spatial distribution of galaxies, once they have merged into larger halos, must be luminosity dependent, such that luminous galaxies become poor tracers of the underlying dark matter.

description: By considering predictors as nodes and their correlation as edges, a graphical structure can be imposed on predictors in a survival model. Some researchers have shown that by incorporating the graphical structure into regularized regression, the accuracy of variable selection and inference would increase. In this study, we present a double penalty in penalized likelihood function for the Cox proportional hazards model with a graphical structure among predictors. The proposed double penalty encourages sparsity not only among groups but also at individual levels. Theoretical properties such as the error bound and asymptotic distribution of the regularized estimators are investigated. Our simulation studies show that the proposed method outperforms the existing methods for the sparse Cox regression model with a graphical structure among predictors. The results of analyzing the progress of primary biliary cirrhosis PBC data also demonstrate the effectiveness of the proposed method.

description: The Municipality of Bečej is located in the eastern part of the Bačka region, one of the lowest part of the Vojvodina province in Serbia. The municipality is mostly located on the loess terrace and alluvial plain, where the characteristics of the water regime of the phreatic aquifer are specific. This researches studies the effects of the natural factors, but also anthropogenic influences that have a high impact on the characteristics of the water regime of the shallowest groundwater horizont. In the study area only 11 monitoring wells are active, which are mostly located in the alluvial plain and loess terrace. Using available data from active and also from nonactive wells, we described the main characteristics of water regime of the phreatic aquifer in the study area. We found that climate characteristics have a significant impact on the water regime of the phreatic aquifer in the higher part of the study area, while hydrologic and anthropogenic factors are more dominant in the lower part of the municipality.

description: Despite prognostic value recognized individually from patient-reported health, electronic health information, and imaging-based phenotypic data, their respective and combined contributions to cardiovascular risk modelling remain uncertain. Our primary aim was to evaluate the individual and combined value of these three data domains for the implementation of personalized risk modelling. This was studied in a broad cardiovascular disease referral population of 9,779 patients undergoing CMR imaging for the prediction of major adverse cardiovascular events (MACE). Ninety features were presented to two machine learning survival prediction algorithms. Performance was compared using C-index, cumulative/dynamic AUC, and integrated Brier score in the test set, demonstrating optimal performance for models with combined access to all three data domains. Shapley values were used to deliver model explainability. A sub-study focussed on the prognostic impact of patient-reported habits demonstrated moderate alcohol consumption of 1-2 drinks/day to be independently associated with a 16% reduction in MACE, active and former smoking associated with increased MACE risk, and caffeinated beverages to have no significant association.Our second aim was to study the capacity of advanced CMR phenotypes to identify associations with a specific cardiovascular outcome of cardiotoxicity using a focussed referral population of 167 patients with cancer. Over 12 months, 54 patients (32%) experienced cardiotoxicity. Adjusting for age, sex, chemotherapy regimen, and baseline left ventricular ejection fraction, several baseline (prechemotherapy) CMR-based 3D strain markers were independently associated with future cardiotoxicity. Multivariable models assessing markers by optimal cut points identified patients with up to 4.7-fold increased odds of future cardiotoxicity based on their prechemotherapy CMR phenotype. A sub-study of 381 patients undergoing prechemotherapy imaging demonstrated cancer to express a unique cardiac phenotype with reduced chamber volumes and elevated strain versus healthy volunteers.Overall, this work demonstrates strong predictive value from the routine capture of high-quality, multi-domain data for the delivery of personalized prediction modelling in broad cardiovascular disease referral populations. Prediction of targeted outcomes in focussed referral populations poses unique challenges; however, can benefit from tailored phenotypic data to identify patients at elevated risk of future outcomes.
Juvenile growth of subalpine fir (Abies lasiocarpa) in the Montane Spruce Ecological Zone of British Columbia Canada
Creators: name: Blenner-Hassett, Trevor
Publisher: name: University of British Columbia
Year: 2013

description: Subalpine fir (Abies lasiocarpa (Hook.) Nutt.) is a widely distributed western North American conifer that can grow under a wide range of light environments, initial densities and site qualities. It can be a major component of stands found within the Thompson Dry Mild variant of the Montane Spruce ecological zone (MSdm2) in the southern interior of British Columbia, Canada. In chapter 2 of this dissertation, I examined the effects of light, moisture, nutrients and neighbor density on juvenile subalpine fir growth. This led me to conclude that: 1) light availability had the largest influence on juvenile tree growth; 2) Delta-13C was the second most important growth predictor; 3) tree size also improved growth predictions; 4) soil moisture was a weak growth predictor; 5) foliar N levels did not improve growth predictions; and 6) density, as expressed as stems/ha, improved growth predictions negligibly. The results from chapter 2 helped to determine the important predictor variables (light and tree size) that were used in investigating the importance of spatially explicit competition on the development of juvenile trees (chapter 3). The chosen spatial model utilized tree size and the crowding effect of neighbors to predict juvenile radial growth. This model was then incorporated into SORTIE-ND as a new juvenile growth behavior, “Juvenile NCI Growth”, and used to test whether juvenile or mature trees have a greater competitive influence on juvenile subalpine fir growth under three basal area classes. Here, I found that juvenile radial growth was faster under the canopy of mature trees than in the neighborhood of similar sized juveniles at the two lowest density classes, 7 and 20 m²/ha. This indicated that symmetric competition processes dominated. I also found that at the highest density class, there were no differences in juvenile radial growth between the two neighbor strata. Chapter 4 was designed to test the influence of site series on growth predictions using SORTIE-ND. I found that site series did have an influence on the growth and development of the stand, as would be expected, which suggests that incorporating site quality into SORTIE-ND would improve growth and yield predictions.
Evidence for spin correlation in ttbar production

description: We present a measurement of the ratio of events with correlated t and tbar spins to the total number of ttbar events. This ratio f is evaluated using a matrix-element-based approach in events with a single lepton (electron or muon) and at least four jets. We analyze ppbar collisions data corresponding to an integrated luminosity of 5.3 fb^-1 collected with the D0 detector at the Fermilab Tevatron collider operating at a center of mass energy $\sqrt{s}=1.96$ TeV. Combining this result with a recent measurement of f in dilepton final states, we find f in agreement with the standard model. In addition, the combination provides evidence for the presence of spin correlation in ttbar events with a significance of more than three standard deviations.

description: Background: The number of new cancer cases is rising in Canada. Incidence rates of chlamydia, gonorrhea, and syphilis have also increased over the last two decades. However, few studies have explored the relationship between these bacterial sexually transmitted infections (STIs) and cancer risk.Purpose: To investigate the risk of primary invasive cancer among individuals with a prior reported diagnosis of chlamydia, gonorrhea, and/or syphilis in Alberta, Canada, from 2000-2019. Methods: This population-based, data-linkage, retrospective cohort study explored seven exposure categories based on prior records of three bacterial STIs. We investigated outcomes for (a) cancers overall, including all cancer sites, and (b) thirteen individual cancer regions. A cohort comprising 175,024 Albertan residents with a reported diagnosis of chlamydia, gonorrhea, and/or syphilis from January 1, 2000, to December 31, 2019, were identified and followed until the development of invasive cancer or death or study end date, whichever happened first. The cancer incidence rate in the STI cohort was compared with the cancer incidence rate in the general population of Alberta using standardized incidence ratios (SIR) and absolute excess risk (AER) with 95% confidence intervals (CI).Results: We identified 1,593 subsequent first primary invasive cancers and in-situ bladder carcinomas during the 1,385,580 person-years of observation (median follow-up=7.3 years; IQR=3.4-11.9). We did not find increased or decreased risk for cancers overall associated with any of the seven exposure categories. However, an increase in risk was identified for cancers of female genital organs (SIR=1.4, 95%CI=1.2,1.6; AER=0.6, 95%CI=0.3,0.9) and male genital organs (SIR=1.5, 95%CI=1.2,1.8; AER=1.1, 95%CI=0.5,1.8) among those exposed to chlamydia only; cancers of digestive organs in case of exposure to gonorrhea only (both sexes combined: SIR=1.4, 95%CI=1.02,2.0; AER=1.6, 95%CI=0.0,3.2); cancers of respiratory and intrathoracic organs (both sexes combined: SIR=1.7, 95%CI=1.1,2.5; AER=3.8, 95%CI=0.2,7.3), as well as cancers of hematopoietic and reticuloendothelial system (both sexes combined: SIR=1.6, 95%CI=1.02,2.3; AER=3.3, 95%CI=-0.3,6.8) in case of syphilis only exposure; and cancers of female genital organs among those exposed to chlamydia and gonorrhea (SIR=1.9, 95%CI=1.2,3.0; AER=1.2, 95%CI=0.1,2.2). Conclusion: Overall findings of this study suggest a possible role of common bacterial STIs in carcinogenesis.
Exploring the longitudinal experiences of physicians transitioning to unsupervised practice: A realist study

description: Problem: The transition from residency to unsupervised practice is a longitudinal process that is fraught with challenges. Most new attendings do not feel adequately prepared or supported for their new roles and responsibilities. We need to better understand the challenges physicians face transitioning to unsupervised practice.Method of Study: The study aim was to explore the different mechanisms that shape a physician’s ability to successfully transition to unsupervised practice. As the transition to unsupervised practice is complex and highly context-dependent, a qualitative realist evaluation study design was used to explore how different factors (mechanisms) can lead to different outcomes for different individuals transitioning to practice. Participants in a variety of specialties were recruited for semi-structured interviews at three points in time - one in the final months of residency, and two at different points in their first year in unsupervised practice. Conclusion: Eight middle-range theories were developed from the data covering: the varying opportunities and challenges participants faced whether or not they stayed at the institutions they trained at, the challenges of learner supervision, the effects of fellowship training, how variable their practice was compared to what they were exposed to in residency training, the timing of orientation or training sessions, being hired into a locum contract, and how sheltered trainees were from the realities of unsupervised practice. Each of these theories have implications for key stakeholders. Residency programs should expose their trainees to the breadth of practice available in each specialty and provide resident autonomy that reflects realistic experiences of unsupervised practice. Departments should have formalized mentorship programs, shadow shifts, and site and department specific orientations. In addition, they should strive to protect new staff from unnecessary stressors through a graduated increase in responsibilities. Both residency programs and departments should provide sessions regarding the new supervisory role, specifically teaching how to manage senior learners and learners in difficulty.

description: This Letter presents a search for contact interactions in the dielectron and dimuon channels using data from proton-proton collisions produced by the LHC at sqrt(s) = 7 TeV and recorded by the ATLAS detector. The data sample, collected in 2011, corresponds to an integrated luminosity of 1.08 and 1.21 fb^-1 in the e+ e- and mu+ mu- channels, respectively. No significant deviations from the standard model are observed. Using a Bayesian approach with a prior flat in 1/Lambda^2, the following 95% CL lower limits are placed on the energy scale of llqq contact interactions: Lambda^- > 10.1 TeV (Lambda^+ > 9.4 TeV) in the electron channel and Lambda^- > 8.0 TeV (Lambda^+ > 7.0 TeV) in the muon channel for constructive (destructive) interference in the left-left isoscalar contact interaction model. Limits are also provided for a prior flat in 1/Lambda^4.

description: We propose a new approach to study coideal algebras. It is well-known that Manin triples (or equivalently Lie bi-algebra structures) are the requirement to deform Lie algebras and to obtain quantum groups. In this paper, introducing some particular automorphisms of Manin triples, we define new structures that we call Lie bi-ideal structures. A link with coisotropic subalgebras is explained. We show that their deformation provide coideal algebras. As examples, we recover from our general construction the twisted Yangians, the q-Onsager algebra and the augmented q-Onsager algebra. As an important by-product, we find a new presentation for the twisted Yangians.

description: In the last 20 years, sustainability has been the major driving factor regardless of the field of research. The search for greener, more environmentally friendly alternative materials has garnered significant pace, especially in the last decade. 5-hydroxymethylfurfural (HMF) is one of the most versatile platform chemicals that can be derived from biomass. HMF can be upgraded into various value-added chemicals via hydrogenation, furan ring-opening reactions and especially oxidation. Two major products derived from HMF oxidation are 2,5-furandicarboxyaldehyde (DFF) and 2,5-furandicarboxylic acid (FDCA). Herein, we have studied a one-pot photocatalytic system using undoped ZnIn2S4 as the catalyst to convert HMF into DFF using acetonitrile as the solvent and oxygen atmosphere. 91.1% HMF conversion with a 99.4% selectivity of DFF in 1 hour was observed in these tests. However, the photocatalyst performance significantly decreased during recycling tests due to inevitable photcorrosion of metal sulfides. Further, electrocatalytic studies were carried out using CoS and CoPS as bifunctional catalysts for HMF oxidation to FDCA on cathodic side of an H-cell and hydrogen evolution (HER) on the anodic side. 100% conversion of HMF with a 98.2% selectivity of FDCA in 1M KOH as the electrolyte was observed. One takeaway from this process was the 99% faradaic efficiency of the reaction system. Intrinsically designed metal sulfides and metal phosphosulfides have the potential to be used as photo-electrocatalysts which is touted to be the next big step in the field of heterogeneous catalysis. Research now must be directed towards synergistically combining these processes along with upcoming bio-enzymatic base free oxidation of HMF to potentially scale-up biomass valorization.

description: The prevalence of infertility in Canada has substantially increased over the last 30 years with one in six couples seeking medical intervention, many of which rely on assisted reproductive technologies (ARTs) including in vitro fertilization (IVF) and in vitro culture (IVC) of embryos. In clinical IVF programs, embryos undergo extended culture until the blastocyst stage (~6 days) under 5% or 2% O2 concentrations to facilitate success of single embryo transfer. Modest success rates of these culture systems warrant further research to refine culture conditions. The objectives of this study were to characterize stress-related responses of cultured embryos under 5% and 2% O2 in comparison to in vivo-derived blastocysts using a CD1 mouse model. We hypothesized 2% O2 during mouse in vitro embryo culture compromises developmental competence through altered transcriptional profiles of genes involved in the embryonic stress response and apoptosis relative to 5% O2-cultured and in vivo-derived blastocysts. The relative expressions of a cohort of stress-related genes in mouse blastocysts cultured under 5 or 2% O2 were quantified through RT-qPCR and compared to in vivo¬-derived embryos. Apoptotic responses were evaluated using an immunofluorescence assay specific for Caspase-3 as the executioner protein in apoptosis. The mean percentage of blastocysts developed in vivo or cultured under 5% O2 was significantly higher than those cultured under 2% O2. Furthermore, in vivo-derived embryos, or those cultured under 5% O2, had greater total cell numbers relative to those cultured under 2% O2. The expansion status of blastocysts was also greatest in embryos cultured under 5% O2. In general, stress response genes were significantly upregulated in embryos cultured under 2% O2, and the expression of antioxidant-related genes was significantly lower in cultured embryos versus those derived in vivo. Caspase-3 immunofluorescence was significantly higher in cultured embryos versus in vivo-derived embryos.Therefore, we inferred that 5% O2 systems may be optimal for culture of mouse embryos, warranting critical evaluation of culturing human embryos under continuous 2% O2 concentrations during clinical IVF programs.

description: The heterogeneous A11 nucleus is the primary direct source of spinal dopamine in rodents. Previous work has implicated this region in nociception, locomotion, and sociosexual behaviours in various animal models. The A11’s activity patterns in freely moving animal models have not been researched. I examined the A11 region’s activity through fibre photometry in mice during various behavioural contexts to elucidate this region’s roles. I found that the A11 regional activity was most excited by novel stimuli. Goal-directed locomotion was associated with increased A11 activity, while locomotion in the open field was on par with baseline fluorescence levels. During states of lower anxiety in the open arms of the elevated plus maze, I also observed increased A11 activity. The A11’s activity was also increased during periods of ultrasonic vocalization. Overall, I suggest that the A11 responds to novelty by promoting goal-directed locomotion and also encodes sociosexual vocalizations. Additionally, I validated an intersectional viral approach to target spinally-projecting A11 cells in a circuit-dependent manner.

description: In much of the so-called developed world, palliative care for infants occurs in the context of Neonatal Intensive Care Units (NICUs). Scholars and practitioners identified a clear need for coherent delivery of neonatal palliative care; however, it remains an often overlooked aspect of medical care in the NICU. This thesis explores ethical principles involved in decision-making, as well as the barriers, facilitators, and models of care delivery of neonatal palliative care in the literature. It also examines health care practitioner perspectives on these subjects revealed during focus groups. In the context of this qualitative descriptive study, ten focus groups were held with a total of forty-five multidisciplinary participants to collect data on the study question. Identified barriers were: (1) communication challenges, (2) inconsistency of care, (3) discomfort with parental decisions and moral distress, (4) lack of support for NICU team members, (5) lack of education or training for staff, and (6) material and personnel resources for provision of palliative care. Identified facilitators were: (1) compassionate support of families, (2) good communication within teams, (3) consistency of the care team, (4) respect for patient-family differences, and (5) individual expertise within teams. An integrative model was heavily favoured by focus group participants. The implications of this research pursue practical application of findings concerning identified barriers and facilitators towards development of a neonatal-perinatal palliative program in Edmonton. Related recommendations are offered for: communication and collaboration, education and training, support and resources, physical space and environment, and piloting a model of care.
High-field magnetoresistance revealing scattering mechanisms in graphene

description: We show that the type of charge carrier scattering significantly affects the high-field magnetoresistance of graphene nanoribbons. This effect has potential to be used in identifying the scattering mechanisms in graphene. The results also provide an explanation for the experimentally found, intriguing differences in the behavior of the magnetoresistance of graphene Hall bars placed on different substrates. Additionally, our simulations indicate that the peaks in the longitudinal resistance tend to become pinned to fractionally quantized values, as different transport modes have very different scattering properties.

description: The impact of carbohydrate (CHO) availability on time to task failure (TTF) and key physiological responses to exercise at the maximal lactate steady state (MLSS) has not been studied. The primary objective of this thesis was to determine how various levels of CHO availability affected TTF at MLSS. The secondary objectives of this thesis were to explore how changes in CHO availability impacted i) [BLa] and CHO oxidation rates at MLSS and ii) neuromuscular fatigue (NMF) and subjective ratings of fatigue and exertion when exercise is performed at MLSS. A combination of nutritional (carbohydrate [CHO] and placebo [PLA]) and exercise interventions (no exercise [REST] and glycogen depletion [GD]) created four conditions with distinct levels of CHO availability at the time of data collection (RESTCHO > RESTPLA > GDCHO > GDPLA). Specifically, CHO and PLA involved consuming beverages containing 7g or 0g of CHO per kg of body mass, respectively, and REST and GD involved no exercise intervention or a glycogen depletion intervention the evening prior to data collection, respectively. Ten participants (4 females, 6 males) completed this double blinded study. TTF at MLSS was not improved by CHO loading, as RESTCHO (57.1 ± 15.8 min) and RESTPLA (57.1 ± 14.8 min) were not significantly different (p = 1.0); however, TTF was significantly reduced in both GD conditions (p < 0.05), and GDCHO (39.1 ± 8.8 min) had a significantly longer TTF compared to GDPLA (20.6 ± 6.5 min; p < 0.001). Pre-TTF to post-TTF changes in NMF variables were not significantly different between conditions despite the large differences in TTF (p> 0.05). Further, at task failure, there was no significant differences in subjective ratings of fatigue and exertion (p > 0.05); however, prior to the TTF trial, participants reported significantly higher ratings of fatigue in GD conditions compared to rest conditions (p < 0.001), with no significant difference between GD conditions (p > 0.05). Finally, the magnitude of some physiological variables (i.e. [BLa] and RER) were impacted by CHO availability, but the pattern of these responses remained unchanged. These findings indicate that changes in CHO availability hinder MLSS determination through a reduction in TTF (i.e., inability to cycle for 30 min continuously), not via changes in metabolic responses to exercise at MLSS (i.e., [BLa] was stable in all conditions).
