Autonomic nervous system parameters to predict the occurrence of ischemic events after transient ischemic attack or minor stroke
Creators: name: Guan, Ling
Publisher: name: University of British Columbia
Year: 2018

description: Background Stress response is tightly regulated by the autonomic nervous system (ANS) which can be measured by heart rate variability (HRV). Traditional risk factors and acute triggers for ischemic stroke and transient ischemic attack (TIA) are considered as chronic and acute stressors, respectively. These risk factors all contribute to the recurrent ischemic events and are related to ANS dysfunction. The moderate predictive value of ABCD2 score may be due to assessing a limited number of stressors. Aims, Objectives and Hypotheses We proposed to 1) assess whether HRV parameters, as markers of ANS function and stress, can predict secondary ischemic events after TIA or minor stroke, and 2) compare the HRV-based predictive tools with ABCD2 score. We expected that using HRV indicators can enhance the prediction of ischemic events. Methods This is a prospective observational study. Patients developed TIA or minor stroke within 48 hours were eligible. The main study variables included: ABCD2 score, HRV assessment from 24-hour Holter recording, and psychological stress. HRV measurement included calculations of both absolute values and changes of HRV frequency-domain parameters: high frequency (HF), normalized HF, HF+low frequency, and total power. Patients were followed for 90 days to assess the development of outcome events. Logistic regression was employed for data analyses. Area under the curve (AUC) and diagnostic tests were used to assess models’ predictive power. Results Final analyses include data collected from 201 patients. The most useful HRV predictors were Daytime HF changes (AUC=0.70) and Morning HF value (AUC=0.61). AUCs for the Best Stress Model and the Most Practical Model were 0.82 and 0.76, respectively, which were significantly higher than AUC of ABCD2 score (AUC=0.63), p <0.05. The optimal cut-off points for Daytime HF changes and Morning HF might be increase of 12.5% and 50 ms², respectively. The exploratory models that involved both values and changes of HF had AUCs ≥0.82. Conclusions Assessing the effects of stress on ANS may be an innovative way to stratify the risk of TIA or minor stroke. Models using HRV parameters, especially HF, provide superior predictive values to ABCD2 score. Future research is needed to validate these results.

description: We summarize the higher-loop perturbative computation of the ghost and gluon propagators in SU(3) Lattice Gauge Theory. Our final aim is to compare with results from lattice simulations in order to expose the genuinely nonperturbative content of the latter. By means of Numerical Stochastic Perturbation Theory we compute the ghost and gluon propagators in Landau gauge up to three and four loops. We present results in the infinite volume and a→0 limits, based on a general fitting strategy.

description: We study the Selmer group of an elliptic curve over an admissible p-adic Lie extension of a number field F . We give a formula for the Akashi series attached to this module, in terms of the corresponding objects for the cyclotomic Zp-extension and certain correction terms. This extends our earlier work [arXiv:math/0404431], in particular since it applies to elliptic curves having split multiplicative reduction at some primes above p, in which case the Akashi series can have additional zeros.

Entanglement spectrum and entanglement thermodynamics of quantum Hall bilayers at ν=1
Creators: name: Schliemann, John
Publisher: name: Universität Regensburg
Year: 2011
Subjects: subject: 530 Physik

description: We study the entanglement spectra of bilayer quantum Hall systems at total filling factor ν=1. In the interlayer-coherent phase at layer separations smaller than a critical value, the entanglement spectra show a striking similarity to the energy spectra of the corresponding monolayer systems around half-filling. The transition to the incoherent phase can be followed in terms of low-lying entanglement levels. Finally, we describe the connection between those two types of spectra in terms of an effective temperature leading to relations for the entanglement entropy which are in full analogy to canonical thermodynamics.

description: В статье исследованы современные проблемы спектра индикаторов инновационной деятельности в экономике, как одного из наиболее востребованных направлений идентификации сравнительного развития экономик, в т.ч. экономики Российской Федерации и других стран мира, с целью разработки комплексных предложений по вырабатыванию элементов стратегической национальной инновационной политики, постановки задач государственно-частного партнёрства в сфере управления бизнес-инновациями. Объектом исследования является процесс формирования современных индикаторов инновационной деятельности. Предметом исследования являются теоретико-методологические и практические основы обеспечения развития спектра индикаторов инновационной деятельности в экономике. Согласно нашему анализу, основными факторами, сдерживающими инновационную деятельность компаний России (в целом по всем предприятиям без деления на группы) в 2016 году, по оценкам руководителей предприятий, были такие: отсутствие собственных средств, неплатежеспособность заказчиков, а также неблагоприятные условия инвестирования и кредитования. Эти же факторы играли основную роль в сдерживании инновационной деятельности предприятий России и в 2017-2019 гг. Используя научные методы сравнения и обобщения при рассмотрении характеристики предприятий, реализующих инновации в Европе, США и Японии, мы выявили, что полную картину уровня инновационной деятельности в стране нельзя составить, рассматривая исключительно такие показатели, как количество выданных патентов или опубликованных статей, так как развитие инноваций определяется множеством факторов. Степень важности тех или иных из них зависит от архетипа отрасли. К примеру, успешность научных инноваций во многом определяется уровнем затрат на НИОКР, в то время как для потребительских инноваций значительно важнее наличие объемных потребительских рынков или скорость внедрения и распространения инноваций. По-нашему мнению, важное направление дальнейшего практического развития спектра индикаторов инновационной деятельности предприятий в экономике модификация подхода к управлению инновациями, предполагающая внедрение портфельного управления инновационными проектами и исследованиями с учетом развития приоритетных направлений, для чего и необходимо развитие новых вышеуказанных компетенций.

description: Transport and scattering phenomena in open quantum-systems with a continuous energy spectrum are conveniently solved using the time-dependent Schrödinger equation. In the timedependent picture, the evolution of an initially localized wave-packet reveals the eigenstates and eigenvalues of the system under consideration. We discuss applications of the wave-packet method in atomic, molecular, and mesoscopic systems and point out specific advantages of the timedependent approach. In connection with the familiar initial value formulation of classical mechanics, an intuitive interpretation of transport emerges. For interacting many-particle systems, we discuss the efficient calculation of the self-consistent classical transport in the presence of a magnetic field.

description: There’s nothing quite like biking down clogged city streets, weaving in and out of traffic. For short distances, it’s faster than driving. It’s liberating. It’s fun. It also makes it painfully clear that most roads aren’t made for bikes.

We need to get off gasoline-powered vehicles, the same way we need to get off fossil-powered electricity.

I was cut off by yet another driver fixated on his phone while cycling to work, I got to thinking that this is how wind and solar electrons must feel as they try to navigate the electric grid. There, too, the infrastructure and rules were designed for the conventional, fossil fuel-based generators, not their smaller, greener counterparts.

description: В современных условиях неопределенность инновационного развития является основой кризиса системы государственного управления. Синергия государства, бизнеса, общественных организаций призвана обеспечить успешное развитие экономики и социальной сферы государства. Выявлено, что на региональном уровне наблюдается отсутствие значимых результатов инновационного развития, выражающееся в слабом развитии приоритетных отраслей экономики с учетом региональной специфики. Основная гипотеза основывается на том, что ментальные модели восприятия реальности и системное мышление у государственных служащих оказывают значительное влияние на эффективность системы государственного управления. Кадры, способные выстроить системное мышление и трансформировать устаревшие модели процессов регулирования обеспечивают эффективность функционирования организации. Ранжирование основных проблем системы государственного управления, препятствующих инновационному развитию, на основании «Стратегии социальноэкономического развития Республики Крым до 2030 года» и определение приоритетных направлений развития проведены с позиции системного подхода с помощью метода экспертных оценок. В качестве экспертов привлекались представители государственного и муниципального управления Республики Крым. Выявлено, что нежелание брать на себя ответственность и отсутствие эффективной системы взаимодействия между органами государственной власти, низкая степень использования передовых технологий менеджмента, работа «по поручениям», а не «на результат» являются основными препятствиями для совершенствования системы государственного управления и обеспечения высоких темпов роста социально-экономического развития региона. Установлено, что инновационность как ключевая характеристика, выражаемая в креативности и человеческом капитале, требует переосмысления в практическом подходе и развития ментальной модели государственного служащего. Ее применение, наряду с другими зарубежными теоретическими концепциями, требует адаптации к реалиям современного административного кризиса государственного управления.

Electronic properties of graphene and graphene nanoribbons with `pseudo-Rashba' spin-orbit coupling
Creators: name: Stauber, Tobias
name: Schliemann, John
Publisher: name: Universität Regensburg
Year: 2009
Subjects: subject: 530 Physik

description: We discuss the electronic properties of graphene and graphene nanoribbons including ‘pseudo-Rashba’ spin–orbit coupling. After summarizing the bulk properties of massless and massive Dirac particles, we first analyze the scattering behavior close to an infinite mass and zigzag boundary. For low energies, we observe strong deviations from the usual spin-conserving behavior at high energies such as reflection acting as a spin polarizer or switch. This results in spin polarization along the direction of the boundary due to the appearance of evanescent modes in the case of non-equilibrium or when there is no coherence between the two one-particle branches. We then discuss the spin and density distribution of graphene nanoribbons.
Dynamical polarizability of graphene beyond the Dirac cone approximation

description: We compute the dynamical polarizability of graphene beyond the usual Dirac cone approximation, integrating over the full Brillouin zone. We find deviations at ℏω=2t (where t is the hopping parameter) which amount to a logarithmic singularity due to the Van Hove singularity and derive an approximate analytical expression. Also at low energies, we find deviations from the results obtained from the Dirac cone approximation which manifest themselves in a peak spitting at arbitrary direction of the incoming wave vector q. Consequences for the plasmon spectrum are discussed.

Hyperfine induced spin and entanglement dynamics in double quantum dots: A homogeneous coupling approach
Creators: name: Erbe, Björn
name: Schliemann, John
Publisher: name: Universität Regensburg
Year: 2010
Subjects: subject: 530 Physik

description: We investigate hyperfine induced electron spin and entanglement dynamics in a system of two quantum dot spin qubits. We focus on the situation of zero external magnetic field and concentrate on approximation-free theoretical methods. We give an exact solution of the model for homogeneous hyperfine coupling constants (with all coupling coefficients being equal) and varying exchange coupling, and we derive the dynamics therefrom. After describing and explaining the basic dynamical properties, the decoherence time is calculated from the results of a detailed investigation of the short-time electron-spin dynamics. The result turns out to be in good agreement with experimental data.

description: Hypertension, a common risk factor for cardiovascular disease, is usually diagnosed and treated based on blood pressure readings obtained in the clinic setting. Blood pressure may differ considerably when measured inside versus outside of the clinic setting. Over the past several decades, evidence has accumulated on the following 2 approaches for measuring blood pressure outside of the clinic: ambulatory blood pressure monitoring (ABPM) and home blood pressure monitoring (HBPM). Both of these methods have a stronger association with cardiovascular disease outcomes than clinic blood pressure measurement. Controversy exists about whether ABPM or HBPM is superior for estimating risk for cardiovascular disease and under what circumstances these methods should be used in clinical practice for assessing blood pressure outside of the clinic. This review describes ABPM and HBPM procedures, the blood pressure phenotypic measurements that can be ascertained, and the evidence that supports the use of each approach to measuring blood pressure outside of the clinic. It also describes barriers to the successful implementation of ABPM and HBPM in clinical practice, proposes core competencies for the conduct of these procedures, and highlights important areas for future research.
Landauer-Büttiker study of the anomalous Hall effect

Year: 2009
Subjects: subject: 530 Physik

description: We report on Landauer-Büttiker studies of anomalous Hall transport in a two-dimensional electron gas with Rashba spin-orbit coupling and a magnetization provided by localized magnetic moments. Our system is described by a discretized tight-binding model in a four-terminal geometry. We consider both the case of magnetically disordered systems as well as ballistic transport in disorder-free systems with spatially homogeneous magnetization. In the latter case we investigate both out-of-plane and in-plane magnetizations. We numerically establish a close connection between singularities in the density of states and peaks in the Hall conductance close to the lower band edge. Consistent with previous theoretical studies based on diagrammatic perturbation expansions, these peaks occur at Fermi energies where only the lower dispersion branch is occupied. Moreover, for large magnetization the Hall conductance is, along with the density of states, suppressed. This numerical finding can be understood from analytical properties of the underlying model in the limit of an infinite system.

description: I have to admit, we recently published a paper that was wrong.  Well not totally wrong, more like incomplete.  This is how science works we put something forward and people say if they think the idea is solid or needs work. If the latter they hopefully do something productive, like amend the formulae to be more generalizable.  This is what I am hoping happens.  Let me tell you about my errant paper. This paper started as a chat during the closed door session of my doctoral defense. The day was Good Friday, 2008 and I had just given an hour-long presentation on the biogeography, evolution and conservation of Melanesian fishes.  My committee member, Les Kaufman, asked me how the genetic approaches that I had used in my dissertation could help with the shifting baselines of coral reefs.

description: The orbital degrees of freedom are of vital importance in explanation of various phenomena. Among them is the orbital-selective Mott transition (OSMT), which is thought to occur in several materials as Ca$_{2-x}$Sr$_x$RuO$_4$ and La$_{n+1}$Ni${_n}$O$_{3n+1}$. OSMT is usually studied in the infinite-dimension limit, and for the time being, it is not clear if it could survive in one-dimensional (1D) case. There exist two scenarios for the OSMT: upon increasing the interaction in a two-band system i) one of the bands becomes insulating, while the other remains metallic and ii) one of the bands becomes empty, while the other may eventually undergo a single-band Mott insulator transition. In this work, we present a preliminary study of the two-orbital Hubbard model by means of Density Matrix Renormalization Group in 1D at quarter-filling, where the second scenario seems to be realized. In particular, we study the orbital densities, double occupancies and form-factors also in the case of finite inter-orbital inter-site hopping.

Different Types of Integrability and Their Relation to Decoherence in Central Spin Models

Publisher: name: Universität Regensburg
Year: 2010
Subjects: subject: 530 Physik

description: We investigate the relation between integrability and decoherence in central spin models with more than one central spin. We show that there is a transition between integrability ensured by the Bethe ansatz and integrability ensured by complete sets of commuting operators. This has a significant impact on the decoherence properties of the system, suggesting that it is not necessarily integrability or nonintegrability which is related to decoherence, but rather its type or a change from integrability to nonintegrability.
An ecofeminist critique of in/humane biopower : bad faith, speciesism and carnism in "happy meat" marketing
Creators: name: Trapara, Katarina
Publisher: name: University of British Columbia
Year: 2017

description: This thesis uses an interdisciplinary Critical Animal Studies and Foucauldian Studies framework to argue that “humane” animal agribusiness is firmly implicated in the animal-industrial complex and thus poses major ethical, ecological and social justice issues. I use the term in/humane biopower to refer to the discursive power mechanisms used by the meat and dairy industries to control and manipulate public opinion surrounding the “question of the animal” (Derrida 12) as well as questions of ecological sustainability. An intersectional ecofeminist framework, which posits that nonhuman animals have subjectivity and therefore should be given moral and ethical consideration, is used to critique advertisements of “happy meat” as that which reify what Carol J. Adams has called the absent referent, which replaces the animal subject with the object of “meat”. The function of the absent referent is to allow for the moral abandonment of a being while also emptying violence from the language (Adams 41-42). I argue that the ubiquitous symbol of “happy meat” in carnist advertising and marketing is problematic in that it normalizes meat consumption by interpellating the individual as a consumer, not of violence or suffering, but of compassionate products. As my research shows, welfare discourses and regulations that aim to “improve” the lives of farmed animals justify new forms of violence against animals and do not signal the end of animal suffering. Furthermore, I observe that in/humane biopower reflects neoliberal forms of governance and citizenship where individual consumerism is seen as the answer to animal rights and ecological sustainability, rather than the radical political action I argue is necessary to rethink the centeredness of the human in the Anthropocene. I therefore conclude that ecofeminism and Critical Animal Studies alongside a Foucauldian critique of modern power provides fundamentally important lines of moral reasoning and questioning that can lead to truly sustainable and ethical outcomes for ourselves and for those beings with whom we share this planet.

description: We consider a spatially homogeneous and isotropic cosmological model where Dirac spinors are coupled to classical gravity. For the Dirac spinors we choose a Hartree– Fock ansatz where all one-particle wave functions are coherent and have the same momentum. If the scale function is large, the universe behaves like the classical Friedmann dust solution. If however the scale function is small, quantum effects lead to oscillations of the energy-momentum tensor. It is shown numerically and proven analytically that these quantum oscillations can prevent the formation of a big bang or big crunch singularity. The energy conditions are analyzed. We prove the existence of time-periodic solutions which go through an infinite number of expansion and contraction cycles.
Current-induced domain wall motion with adiabatic spin torque only in cylindrical nanowires

description: We investigate current-driven domain wall (DW) propagation in magnetic nanowires in the framework of the modified Landau-Lifshitz-Gilbert equation with both adiabatic and nonadiabatic spin torque (AST and NAST) terms. By employing a simple analytical model, we can demonstrate the essential physics that any small current density can drive the DW motion along a uniaxial anisotropy nanowire even in absence of NAST, while a critical current density threshold is required due to intrinsic anisotropy pinning in a biaxial nanowire without NAST. The DW motion along the uniaxial wire corresponds to the asymptotical DW oscillation solution under high field/current in the biaxial wire case. The current-driven DW velocity weakly depends on the NAST parameter β in a uniaxial wire and it is similar to the β = α case (α: damping) in the biaxial wire. Apart from that, we discuss the rigid DW motion from both the energy and angular momentum viewpoints and point out some physical relations in between. We also propose an experimental scheme to measure the spin current polarization by combining both field- and current-driven DW motion in a usual flat (biaxial) nanowire.

description: We present the results of ab-initio density functional theory based calculations of the stability and reconstruction of zigzag edges in triangular graphene quantum dots. We show that, while the reconstructed pentagon-heptagon zigzag edge structure is more stable in the absence of hydrogen, ideal zigzag edges are energetically favored by hydrogen passivation. Zero-energy band exists in both structures when passivated by hydrogen, however in case of pentagon-heptagon zigzag, this band is found to have stronger dispersion, leading to the loss of net magnetization.

description: Экономическое развитие является движущей силой активных и пассивных процессов и изменений, обеспечивает общественный прогресс. Это движение, которое создает системные преобразования как в рамках мирового, национального, так и регионального хозяйства, создавая необходимые условия для роста всех составляющих процесса воспроизведения экономической и социальной системы. Одной из важнейших таких составляющих является предпринимательские структуры, который формирует фундамент успешного регионального развития, является главным приоритетом для повышения социально-экономического развития страны. Предпринимательство является источником устойчивого экономического роста, стабильности общества и обеспечения занятости в стране, непосредственно влияет на повышение уровня и качества жизни населения. Современное развитие экономики основывается на активном развитии предпринимательской среды. Мировая и отечественная практика свидетельствуют, что необходимым условием успешного функционирования предпринимательских структур является государственная и региональная поддержка. В исследовании проведен анализ дефиниции предпринимательство и рассмотрена сущность поддержки предпринимательства, как процесса последовательных мер со стороны участников экономических отношений, объединенных сетью связей с целью удовлетворения их потребностей и направленных на его эффективное развитие. Выявлена комплексная поддержка предпринимательского сектора, в основе которой лежат механизмы поддержки. Также выделена роль механизма инфраструктурной поддержки предпринимательской деятельности.

description: The dual condensate is a new QCD phase transition order parameter, which connnects confinement and chiral symmetry breaking as different mass limits. We discuss the relation between the fermion spectrum at general boundary conditions and the dual condensate and show numerical results for the latter from unquenched SU(3) lattice configurations.

description: Anisotropic magnetoresistance (AMR) is a relativistic magnetotransport phenomenon arising from combined effects of spin-orbit coupling and broken symmetry of a ferromagnetically ordered state of the system. In this work we focus on one realization of the AMR in which spin-orbit coupling enters via specific spin-textures on the carrier Fermi surfaces and ferromagnetism via elastic scattering of carriers from polarized magnetic impurities. We report detailed heuristic examination, using model spin-orbit coupled systems, of the emergence of positive AMR (maximum resistivity for magnetization along current), negative AMR (minimum resistivity for magnetization along current), and of the crystalline AMR (resistivity depends on the absolute orientation of the magnetization and current vectors with respect to the crystal axes) components. We emphasize potential qualitative differences between pure magnetic and combined electromagnetic impurity potentials, between short-range and long-range impurities, and between spin-1/2 and higher spin-state carriers. Conclusions based on our heuristic analysis are supported by exact solutions to the integral form of the Boltzmann transport equation in archetypical two-dimensional electron systems with Rashba and Dresselhaus spin-orbit interactions and in the three-dimensional spherical Kohn-Littinger model. We include comments on the relation of our microscopic calculations to standard phenomenology of the full angular dependence of the AMR, and on the relevance of our study to realistic, two-dimensional conduction-band carrier systems and to anisotropic transport in the valence band of diluted magnetic semiconductors.
Spins coupled to a spin bath: From integrability to chaos

Subjects: subject: 530 Physik

description: Motivated by the hyperfine interaction of electron spins with surrounding nuclei, we investigate systems of central spins coupled to a bath of noninteracting spins in the framework of random matrix theory. With increasing number of central spins a transition from Poissonian statistics to the Gaussian orthogonal ensemble occurs which can be described by a generalized Brody distribution. These observations are unaltered upon applying an external magnetic field. In the transition region, the classical counterparts of the models studied have mixed phase space.

description: For better or worse publications are the coins of the realm in academia. They represent a basic unit of measurement by which a lab’s productivity can be measured, by which decisions on tenure and promotion are made, and a factor in how grants are allocated. For many young researchers getting that first publication is a tremendous feeling, the first form of professional validation, and proof that those long hours in the lab/field/simulation were all worth it.

The Highest Resolution Mass Map of Galaxy Cluster Substructure To Date Without Assuming Light Traces Mass: LensPerfect Analysis of Abell 1689

description: We present a strong lensing mass model of Abell 1689 which resolves substructures ~25 kpc across (including about ten individual galaxy subhalos) within the central ~400 kpc diameter. We achieve this resolution by perfectly reproducing the observed (strongly lensed) input positions of 168 multiple images of 55 knots residing within 135 images of 42 galaxies. Our model makes no assumptions about light tracing mass, yet we reproduce the brightest visible structures with some slight deviations. A1689 remains one of the strongest known lenses on the sky, with an Einstein radius of RE = 47.0" +/- 1.2" (143 +3/-4 kpc) for a lensed source at zs = 2. We find a single NFW or Sersic prole yields a good fit simultaneously (with only slight tension) to both our strong lensing (SL) mass model and published weak lensing (WL) measurements at larger radius (out to the virial radius). According to this NFW fit, A1689 has a mass of Mvir = 2.0 +0.5/-0.3 x 10^15 Msun / h70 (M200 = 1.8 +0.4/-0.3 x 10^15 Msun / h70) within the virial radius rvir = 3.0 +/- 0.2 Mpc / h70 (r200 = 2.4 +0.1/-0.2 Mpc / h70), and a central concentration cvir = 11.5 +1.5/-1.4 (c200 = 9.2 +/- 1.2). Our SL model prefers slightly higher concentrations than previous SL models, bringing our SL+WL constraints in line with other recent derivations. Our results support those of previous studies which find A1689 has either an anomalously large concentration or significant extra mass along the line of sight (perhaps in part due to triaxiality). If clusters are generally found to have higher concentrations than realized in simulations, this could indicate they formed earlier, perhaps as a result of early dark energy.
