description: The development of systems physiology is hampered by the limited ability to relate tissue structure and function in intact organs in vivo or in vitro. Here, we show the application of a bimodal biophotonic imaging approach that employs optical coherence tomography and fluorescent imaging to investigate the structure-function relationship at the tissue level in the heart. Reconstruction of cardiac excitation and structure was limited by the depth penetration of bimodal imaging to ∼2mm in atrial tissue, and ∼1mm in ventricular myocardium. The subcellular resolution of optical coherence tomography clearly demonstrated that microscopic fiber orientation governs the pattern of wave propagation in functionally characterized rabbit sinoatrial and atrioventricular nodal preparations and revealed structural heterogeneities contributing to ventricular arrhythmias. The combination of this bimodal biophotonic imaging approach with histology and/or immunohistochemistry can span multiple scales of resolution for the investigation of the molecular and structural determinants of intact tissue physiology.

description: Polymeric composites with the hybrid filler network for high-performance electromagnetic interference (EMI) shielding brought increasing interest. Herein, UHMWPE/ground tire rubber (GTR)/conductive carbon black (CCB) (UGC) composites with a hybrid segregated structural CCB- GTR was constructed by solid-phase shear milling (S3M), mechanical blending, and compacted molding processes. The percolation behavior of electrical conductivity and EMI shielding effectiveness (SE) of composites was described using Sigmoidal/Growth models, and its EMI shielding mechanism was discussed. Results showed that the EMI SE of U30G70C20, U50G50C20, and U70G30C20 composites were found to be 37.5 dB, 41.7 dB, and 43.8 dB, respectively, due to constructing a hybrid network. The attenuation rate of microwave radiation is above 99.99%, and the shielding mechanism is mainly electrical loss. Moreover, the relationship between electrical conductivity and EMI SE is consistent with Sigmoidal/Growth models, indicating that Sigmoidal/Growth models can successfully predict the percolation threshold of the EMI SE of UGC composites.

description: Federal and state unemployment insurance (UI) programs are in a fiscal crisis.  In the current period of high unemployment and economic crises, state UI trust funds are increasingly insolvent.  Many states also have borrowed federal monies to fund their UI trust funds.  As a result, the states are facing significant loan and interest repayments in addition to insolvent trust funds.  This article examines the federal-state UI system, case studies on two states, and options for short-term and future UI trust fund solvency.

description: We report a dynamical formation of a (Mott) gap from holographic fermions. By coupling a fermion field with dipole action to the charged dilaton black branes with a Lifshitz like IR geometry and $AdS_{4}$ boundary, we find that when the dipole interaction is large enough, spectral weight is transferred between bands, and beyond a critical dipole interaction, a gap emerges in the fermion density of states. The value of the gap becomes larger as the strength of the interaction keeps increasing.

Population oscillations in spatial stochastic Lotka-Volterra models: A field-theoretic perturbational analysis

description: Field theory tools are applied to analytically study fluctuation and correlation effects in spatially extended stochastic predator-prey systems. In the mean-field rate equation approximation, the classic Lotka-Volterra model is characterized by neutral cycles in phase space, describing undamped oscillations for both predator and prey populations. In contrast, Monte Carlo simulations for stochastic two-species predator-prey reaction systems on regular lattices display complex spatio-temporal structures associated with persistent erratic population oscillations. The Doi-Peliti path integral representation of the master equation for stochastic particle interaction models is utilized to arrive at a field theory action for spatial Lotka-Volterra models in the continuum limit. In the species coexistence phase, a perturbation expansion with respect to the nonlinear predation rate is employed to demonstrate that spatial degrees of freedom and stochastic noise induce instabilities toward structure formation, and to compute the fluctuation corrections for the oscillation frequency and diffusion coefficient. The drastic downward renormalization of the frequency and the enhanced diffusivity are in excellent qualitative agreement with Monte Carlo simulation data.

description: America was built on the ideal of an open promise to those hard-working individuals that wished to create their own future: The American Dream. Naturally under this model, individualistic enterprise and opportunistic bravado amalgamated and withstood the test of time to become central tenets of American culture. Yet the question remains: Is the American mode of thought sustainable for all individuals in society? By analyzing the state of America in 2020 it is clear that our nation is still plagued by a plethora of social and political problems. Seemingly, with every tweet from our current President, it is as if our nation becomes more and more polarized in our thoughts and actions on a day-by-day basis. Ultimately, I believe our country’s cultural values can learn from the Buddhist perspective in order to become more compassionate and humane citizens for each other and our planet. While the pursuit of economic prowess seems almost instinctive under our country’s mode of thought, it is not naïve to believe that general compassion can be respected and imparted to all.

description: Small and large estates all over Europe represent major partners in the conservation of biodiversity; they provide space, shelter and living conditions for some of our most iconic species. From the running white-tailed deer of Finland to flights of migrating birds in Spain, estates often provide room for such animals to thrive. The Wildlife Estates project aims to establish a network of exemplary estates. These estates/territories will showcase the simple principles of good management and conservation of wildlife estates all over Europe. After 10 years of experience, more than 150estates in 17 countries and close to 1.000.000 ha labelled, the Wildlife Estates (WE) Label has perfected its method of creating biodiversity, which in turn generates economic, social and ecological stability. Our objective is simple. Use the land to its fullest potential, in a respectful manner, so as to create long term benefits. Apart from a highly beneficial exchange of experience, the initiative has established simple but precise principles for the good territorial management and conservation of 'wildlife' territories throughout Europe, divided up according to the different biogeographical regions of the European Union. The WE label has been developed to recognize and admit good and exemplary management of territories. It creates a system which ensures and demonstrates that the management and the use of natural resources on relevant estates comply with biodiversity and nature conservation principles and aims to be flexible and reproducible. This is why the WE Label is vital; to combine careful management practice with conservation – a private commitment to working for the public good. All those who commit to our principles do so on a voluntary basis, not because their hand is forced by regulation, but because they have a healthy respect for the maintenance of biodiversity. In many cases, this is not only good for nature, but a diverse and healthy estate can provide even more benefits like increased pollination, especially when the aims of the WE Label are combined with those of our Pollinator Network initiative.

description: We consider a quantum field which is in a Hartle-Hawking state propagating in a general spherically symmetric black hole space-time. We make use of uniform approximations to the radial equation to calculate the components of the stress tensor, renormalized using the Hadamard form of the Green's function, on the horizons of this space-time. We then specialize these results to the case of the `lukewarm' Reissner-Nordstrom-de Sitter black hole and derive some conditions on the stress tensor for the regularity of the Hartle-Hawking state.

description: The hallmark of a successful response to a nuclear detonation will be the resilience of the community, region, and nation. An incident of this magnitude will rapidly become a national incident; however, the initial critical steps to reduce lives lost, save the lives that can be saved with the resources available, and understand and apply resources available to a complex and dynamic situation will be the responsibility of the local and regional responders and planners. Expectations of the public health and health care systems will be met to the extent possible by coordination, cooperation, and an effort to produce as consistent a response as possible for the victims. Responders will face extraordinarily stressful situations, and their own physical and psychological health is of great importance to optimizing the response. This article illustrates through vignettes and supporting text how the incident may unfold for the various components of the health and medical systems and provides additional context for the discipline-related actions outlined in the state and local planners’ playbook.
Documenting the impact of outliers on decisions about the number of factors in exploratory factor analysis
Creators: name: Liu, Yan
Publisher: name: University of British Columbia
Year: 2011

description: The overall purpose of this dissertation is to investigate how outliers affect the decisions about the number of factors in exploratory factor analysis (EFA) as determined by four widely used and/or highly recommended methods. Very few studies have looked into this issue in the literature and the conclusions are contradictory— i.e., with studies disagreeing as to whether outliers result in extra factors or a reduced number of factors. For this dissertation I systematically studied the impact of outliers arising from different sources and matched outlier simulation models with different type of outliers. Chapter 1 provides an overview of the gap between statistical theory regarding outliers and researchers’ day-to-day practice and their understanding of the effects of outliers. Chapter 2 presents a review of EFA with an emphasis on the four commonly used or highly recommended decision methods on the number of factors as well as a review of outliers which includes the sources of outliers and problems of outliers in factor analysis. Chapter 3 examines the effects of outliers arising from errors using the deterministic and slippage models. The results revealed that outliers can inflate, deflate, or have no effects on the decisions about the number of factors, which depends on the decision method used and the magnitude and number of outliers. Chapter 4 investigates the effects of outliers arising from an unintended and unknowingly included subpopulation using the mixture contamination model. The general conclusions are similar to chapter 3, but chapter 4 also reveals that symmetric and asymmetric contamination has different effects on different decision methods and the effects of outliers do not depend on sample size. Chapter 5 provides a general discussion of the findings of this dissertation, describes four novel contributions, and points out the limitations of the present research as well as the future research directions. This dissertation aims to bridge the gap from day-to-day researchers’ practice and understanding of the effects of outliers to current outlier research that emphasizes robust statistics. The findings of this dissertation address the contradictory conclusions made in previous studies.

description: It has been proposed that the terror itself that results from a terrorist
attack elicits what is perhaps one of the attack’s more profound
consequences: a direct assault on the population’s mental health.
Prior research suggests that in the context of a mass disaster, children may be an especially vulnerable group. Previous research has shown that direct
exposure to different types of mass traumatic events is associated with an increase in posttraumatic stress symptoms among children. Postdisaster studies have also reported elevated prevalence of physical symptoms,  anxiety, and depression, which are frequently comorbid with posttraumatic
stress reactions among youth. Previous studies examining the results of mass trauma on child mental health have included selected or volunteer samples at the trauma site. Studies to date have not examined population-based samples; therefore, the extent to which results generalize to youth in the community, or to different levels of exposure, is not known. Moreover, previous studies have focused mainly on posttraumatic stress disorder (PTSD), and have not assessed a range of mental disorders. Several publications have documented the impact of September 11 on adults’ mental health; studies published to date have not yet directly assessed children, although some did elicit parental reports. This article reports the results of the New York City, NY, Department of Education (formerly the New York City Board of Education) study, which examined the prevalence of 8 probable mental disorders and their relationship to levels of exposure to the World Trade Center (WTC) attack in a large representative sample of New York City public school children 6 months following this disaster.

description: Waveguides of subwavelength dimensions with asymmetric geometries, such as rib waveguides, can display nonlinear polarization effects in which the nonlinear phase difference dominates the linear contribution, provided the birefringence is sufficiently small. We demonstrate that self-flipping polarization states can appear in such rib waveguides at low (mW) power levels. We describe an optical power limiting device with optimized rib waveguide parameters that can operate at low powers with switching properties.

description: An exemplar group of disaster mental health subject matter experts was formed as part of the CDC Center for Public Health Preparedness program to develop a "toolkit' of relevant CPHP disaster mental health training and education curricula and resources. The group developed a charter, compiled relevant CPHP training materials, developed an objective review template, and collectively reviewed the assembled resources. Curricular reviews were presented at a March 2005 meeting where an asset matrix was developed to categorize and compare the training and education curricula and
resources. This article describes findings and next steps for toolkit development and refinement. Some recommendations for the toolkit identified thus far are to develop standardized disaster mental health nomenclature, add training exercises to the array of CPHP training and education resources, develop disaster mental health competencies for public health workers, add more advanced trainings to the current repertoire, and add resources to the toolkit during the coming years. The group also plans to disseminate the mental health/psychosocial preparedness toolkit to practice partners engaged in training disaster response personnel.

description: Mongolia is a semi-arid and arid country in Asia where the climate has been changing more drastically than many other locations across the globe. The proceedings of the "Trans-disciplinary Research Conference: Building Resilience of Mongolian Rangelands" is divided into five sections: 1) Rangeland Ecology and Management, 2) Climate Change and Hydrology, 3) Institutional Innovations in Mongolian Rangelands, 4) Social and Economic Development in Rural Mongolia, and 5) Methods of Knowledge and Data Integration. The papers presented provide cause for concern regarding observed changes in climate, rangeland conditions and livestock populations, as well as reasons for hope and motivations for action to address the current challenges. We hope that this volume and the conference it accompanies, will inspire renewed commitment to support science and science-based policy-making and management to sustain Mongolia's unique natural and cultural heritage as they adapt to a changing planet.

Mesoscopic transport of fermions through an engineered optical lattice connecting two reservoirs

Year: 2011
Subjects: subject: Quantum Gases (cond-mat.quant-gas)

description: We study transport of fermions in a system composed of a short optical lattice connecting two finite atomic reservoirs at different filling levels. The average equilibration current through the optical lattice, for strong lattice-reservoir coupling and finite temperatures, is calculated within the Landauer formalism using a nonequilibrium Green's functions approach. We moreover determine quantum and thermal fluctuations in the transport and find significant shot-to-shot deviations from the average equilibration current. We show how to control the atomic current by engineering specific optical lattice potentials without requiring site-by-site manipulations and suggest the realization of a single level model. Based on this model we discuss the blocking effect on the atomic current resulting from weak interactions between the fermions.

A health care operations research analysis of elderly fallers' emergency department services utilization and cost
Creators: name: Woolcott, John Clifford
Publisher: name: University of British Columbia
Year: 2012

description: Introduction: Falls in the elderly are a significant cause of morbidity. Prescription medication use has been identified as an independent risk factor for falls. Among all Emergency Department (ED) presentations by elderly persons, 14-40% are due to falls, placing considerable strain on ED resources. Aims: In my thesis I aimed to 1) Provide updated estimates of the association between the use of specific medications and falling, 2) Determine whether the care provided to elderly fallers while patients in the ED follows published recommendations and was provided in a timely fashion, 3) Estimate the cost per fall resulting in an ED presentation, 4) Design a discrete event simulation (DES) model simulating care and then simulating other approaches to care including hypothetical changes. Methods: 1) A Bayesian meta-analysis of studies assessing the association between specific classes of medication use and risk of a fall. 2) A cohort study of elderly fallers presenting to the ED. 3) DES of the ED care received by elderly fallers. Results: Use of anti-hypertensives, diuretics, sedatives and hypnotics, neuroleptics and anti-psychotics, antidepressants, benzodiazepines, and non-steroidal antiinflammatory drugs are associated with an increased risk of falling. 1) In a sample of 101 ED fall presentations, 38% of elderly fallers leave the ED without a geriatric assessment and 14% are assessed by a physiotherapist. Less than 8% of fallers received care which met the wait time benchmarks. The estimated cost per fall causing an ED presentation is $11,408 with the cost per fall-related hospitalization estimated to be $29,363. 2) Providing care in a timely fashion could significantly reduce the time an elderly faller spends in the ED and the opportunity costs associated with waiting to be seen by physician or admission to hospital. Summary: Many commonly used medications are associated with falls. The care provided by the elderly faller in the ED does not currently meet the recommendations of published guidelines, nor is it provided in a timely fashion. The economic burden of falls is significant. By not providing ED care that meets recommended wait time benchmarks significant opportunity costs are incurred by the ED.

На основе опубликованных источников и документов российских, армянских и грузинских архивов реконструируется внешняя политика европейских держав, России и США, которые в экономическом, политическом и гуманитарном отношении были вовлечены в проблемы положения армянского населения, проживавшего компактно на российском Кавказе и в Западной Армении. Впервые в российской историографии предлагается комплексное видение подходов и реальной политики всех участников событий относительно проблемы осуществления реформ на армянских территориях Османской империи. Кроме того, выявлены основные этапы эволюции Армянского вопроса в связи с Первой мировой войной и последующими революциями в России и Турции. Логическим завершением Восточного, а соответственно и Армянского вопроса представляется Лозаннский договор, окончательно отказавший армянскому населению в собственном государстве.

description: We discuss classical integrable structure of two-dimensional sigma models which have three-dimensional Schrodinger spacetimes as target spaces. The Schrodinger spacetimes are regarded as null-like deformations of AdS_3. The original AdS_3 isometry SL(2,R)_L x SL(2,R)_R is broken to SL(2,R)_L x U(1)_R due to the deformation. According to this symmetry, there are two descriptions to describe the classical dynamics of the system, 1) the SL(2,R)_L description and 2) the enhanced U(1)_R description. In the former 1), we show that the Yangian symmetry is realized by improving the SL(2,R)_L Noether current. Then a Lax pair is constructed with the improved current and the classical integrability is shown by deriving the r/s-matrix algebra. In the latter 2), we find a non-local current by using a scaling limit of warped AdS_3 and that it enhances U(1)_R to a q-deformed Poincare algebra. Then another Lax pair is presented and the corresponding r/s-matrices are also computed. The two descriptions are equivalent via a non-local map.

description: This study estimates 2007 national poverty rates using an approach largely conceptualized by a 1995 National Academy of Sciences panel and similar to the supplemental poverty measure that will soon be produced by the U.S. Census Bureau. The study uses poverty thresholds based on expenditures for shelter, food, clothing, and utilities as well as a measure of family income that includes earnings, cash transfers, near-cash benefits, tax credits, and tax payments. The measure also accounts for child care, work, and out-of-pocket medical expenses; variation in regional cost of living; and mortgage-free homeownership. Under this method, the rate of poverty is estimated to be higher than the rate calculated in the traditional manner, rising from 12.4 percent in the official measure to 16 percent in the new measure; the rate of child poverty is more than 3 percentage points higher, and elderly poverty is nearly 7 points higher.

description: We construct a new entanglement-assisted quantum polar coding scheme which achieves the symmetric coherent information rate by synthesizing "amplitude" and "phase" channels from a given, arbitrary quantum channel. We first demonstrate the coding scheme for arbitrary quantum channels with qubit inputs, and we show that quantum data can be reliably decoded by O(N) rounds of coherent quantum successive cancellation, followed by N controlled-NOT gates (where N is the number of channel uses). We also find that the entanglement consumption rate of the code vanishes for degradable quantum channels. Finally, we extend the coding scheme to channels with multiple qubit inputs. This gives a near-explicit method for realizing one of the most striking phenomena in quantum information theory: the superactivation effect, whereby two quantum channels which individually have zero quantum capacity can have a non-zero quantum capacity when used together.

Disaster victims--Psychological aspects

description: During and after disasters, pediatricians can assist parents and community leaders not only by accommodating the unique needs of children but also by
being cognizant of the psychological responses of children to reduce the possibility of long-term psychological morbidity. The effects of disaster on children are mediated by many factors including personal experience, parental reaction, developmental competency, gender, and the stage of disaster response. Pediatricians can be effective advocates for the child and family and at the community level and can affect national policy in support of
families. In this report, specific children’s responses are delineated, risk factors for adverse reactions are discussed, and advice is given for pediatricians to ameliorate the effects of disaster on children.

description: In this paper, we explore experimentally the phase behavior of a dense active suspension of self- propelled colloids. In addition to a solid-like and a gas-like phase observed for high and low densities, a novel cluster phase is reported at intermediate densities. This takes the form of a stationary assembly of dense aggregates, with an average size which grows with activity as a linear function of the self-propelling velocity. While different possible scenarii can be considered to account for these observations - such as a generic velocity weakening instability recently put forward -, we show that the experimental results are reproduced by a chemotactic aggregation mechanism, originally introduced to account for bacterial aggregation, and accounting here for diffusiophoretic chemical interaction between colloidal swimmers.

description: The Poynting-Robertson Cosmic Battery proposes that the innermost part of the accretion disk around a black hole is threaded by a large scale dipolar magnetic field generated in situ, and that the return part of the field diffuses outward through the accretion disk. This is different from the scenario that the field originates at large distances and is carried inward by the accretion flow. In view of the importance of large scale magnetic fields in regulating the processes of accretion and outflows, we study the stability of the inner edge of a magnetized disk in general relativity when the distribution of the magnetic field is the one predicted by the Poynting-Robertson Cosmic Battery. We found that as the field grows, the inner edge of the disk gradually moves outward. In a fast spinning black hole with a>0.8M the inner edge moves back in towards the black hole horizon as the field grows beyond some threshold value. In all cases, the inner part of the disk undergoes a dramatic structural change as the field approaches equipartition.

description: An informed understanding of the subsurface is critical for mining, tunnelling, wastewater injection, carbon sequestration, and hydraulic fracturing (HF). Unfortunately, subsurface characterization is full of uncertainty. This is especially true when trying to understand or mitigate induced seismicity (IS), or the triggering of earthquakes by anthropogenic processes. This research focuses on hydraulic fracturing caused IS in unconventional reservoirs. The interaction between HF and IS is complicated by geomechanical variability and the presence of natural fractures. Our research accomplishes three objectives. We study natural fractures through outcrop analogues, discrete fracture network modelling, and induced seismicity. We characterise geomechanical rock properties along with their uncertainty. Finally, we develop a repeatable and scalable workflow to separate HF microseismicity from IS in order to characterise hydraulic and natural fractures. The research focuses on the Duvernay Formation in the Western Canadian Sedimentary Basin. An alpine outcrop equivalent of the Duvernay is characterized to quantify small- and large-scale fractures. This study reveals irreducible small-scale heterogeneity, as well as discernable patterns in large-scale fractures. Statistics and geostatistics are used to investigate elastic moduli and brittleness. The work shows how measurement and modelling uncertainity can propogate from laboratory to basin-scale. It reveals fundamental differences between elastic moduli and brittleness and shows why holistic modelling and uncertainty quantification approaches are essential to understanding and modelling the subsurface. We then introduce methods for the separation of HF microseismicity from IS. Physics-based clustering and Bayesian inference of diffusivity are used for the separation. This permits HF characterization which highlights the large variability of diffusivity and HF dimensions. We show why physics-based constraints are essential for microseismic analysis. The separated IS allows us to infer information about the natural fractures linked with induced seismicity. Application of the methods to the Duvernay shows HFs propogating directly into natural fractures and rotating away from the maximum principal stress direction towards natural fractures. Discrete fracture network modelling and parameter estimation is able to constrain the architecture of multiple fracture sets. We demonstrate that aseismic fracture sets are essential for establishing pressure connectivity and displaying IS.
