description: The Confederation Bridge is the longest bridge to span ice covered waters in the world. To process the abundance of sonar data collected at the Bridge, two macro programs were created. Sonar data from 2007 and 2008 data collected by the ice force monitoring program were processed using the macros. Ice depth data was obtained from sonar instrumentation and then combined with video and pressure data to produce two dimensional keel cross-sections. Keel depth, width, leading angle, trailing angle, bottom width, and area are identified for each cross-section. Keel cross-sections are then matched to the ice load at the likely interaction time and checked for possible relationships. Maximum keel depths were less than those predicted during Bridge design. However, the probability of exceedance of keel depths observed is close to the design distribution. Almost no relationship was observed between keel geometric properties and load in the overall data.

description: Presented at the Protections 2016: 2nd international seminar on dam protection against overtopping: concrete dams, embankment dams, levees, tailings dams held on 7th-9th September, 2016, at Colorado State University in Fort Collins, Colorado, USA. The increasing demand for dam and levee safety and flood protection has motivated new research and advancements and a greater need for cost-effective measures in overtopping protection as a solution for overtopping concerns at levees and dams. This seminar will bring together leading experts from practice, research, development, and implementation for two days of knowledge exchange followed by a technical tour of the Colorado State University Hydraulic Laboratory with overtopping flume and wave simulator. This seminar will focus on: Critical issues related to levees and dams; New developments and advanced tools; Overtopping protection systems; System design and performance; Applications and innovative solutions; Case histories of overtopping events; Physical modeling techniques and recent studies; and Numerical modeling methods.

description: Roller compacted concrete (RCC) is frequently used to armor earthen embankments for passing extreme floods and to construct gravity dams and stepped spillways. Early experience on RCC dam applications in the 1980s showed a tendency for seepage to develop along the lift lines. Therefore, RCC dam designers started including an upstream facing system as a watertight barrier. An alternative facing material that has been used extensively overseas and is starting to gain more widespread acceptance in the United States is Grout Enriched RCC (GERCC). The grout enriched method of face construction has been shown to be less expensive than other facing options, particularly on larger dam projects, and has also been used on exposed RCC embankment overtopping projects. However, in the United States, the use of GERCC technology has been fairly limited, primarily due to concern over the material's freeze-thaw resistance. The objective of this project is to develop a grout formulation and construction technique that allows the production of air entrained GERCC. The study includes four phases to systemically achieve this objective: (1) optimizing grout formulation, (2 and 3) evaluation of small scale laboratory samples of GERCC, and (4) conducting a field trial. This paper focuses on the final phase, a field trial conducted with ASI contractors at the Duck River Dam site located in Alabama. The results show that the adequate freeze thaw resistance can be attained by air entraining GERCC, but the results are very sensitive to the distribution of the grout through the RCC and adequate performance requires significant internal vibration.

description: We examined baseline data from the Systolic Blood Pressure Intervention Trial (SPRINT) to investigate whether medication adherence, measured by the 8-item Morisky Medication Adherence Scale (MMAS-8), was associated with systolic blood pressure (SBP) and whether MMAS-8 score and number of antihypertensive medications interacted in influencing SBP. A total of 8435 SPRINT participants were included: 21.2% had low adherence (MMAS-8: <6); 40.0% had medium adherence (6 to <8); and 38.8% had high adherence (8). SBP was <140 mm Hg in 54.6%; 140–160 mm Hg in 36.6%; and >160 mm Hg in 8.8%. In multivariable regression, medium vs. low adherence weakly associated with lower SBP (odds ratio: 1.17; confidence interval: 1.04, 1.31). SPRINT eligibility criteria should be considered when interpreting results. Efforts to understand and enhance adherence are crucial to improve population health, and using self-report instruments might be considered for predicting treatment adherence and response in future efficacy trials and for identifying patients for adherence support in clinical practice.

Background To reduce the malaria burden and improve the socioeconomic status of its citizens, the Democratic Republic of Congo scaled up key malaria control interventions, especially insecticide-treated nets (ITNs), between 2005 and 2014. Since then, the effects of these interventions on malaria mortality and morbidity have not been assessed. This study aimed to measure the impact of the National Malaria Control Programme’s efforts and to inform future control strategies. Methods The authors used data from the Demographic and Health Surveys 2007 and 2013–2014 to assess trends in all-cause childhood mortality (ACCM) against trends in coverage of malaria interventions at national and subnational levels. The authors used the plausibility argument to assess the impact of the malaria control interventions and used Kaplan–Meier survival probability and Cox proportional hazard models to examine the effect of ITN ownership on child survival. Contextual factor trends affecting child survival were also considered. Results Countrywide, household ownership of at least one ITN increased, from 9% in 2007 to 70% in 2013–2014. All provinces experienced similar increases, with some greater than the national level. ITN use increased between 2007 and 2013–2014 among children under five (6% to 55%). Severe anaemia (haemoglobin concentration < 8 g/dl) prevalence among children aged 6–59 months significantly decreased, from 11% (95% confidence interval [CI] 9–13%) in 2007 to 6% (95% CI 5–7%) in 2013–2014. During the same period, ACCM declined, from 148 (95% CI 132–163) to 104 (95% CI 97–112) deaths per 1000 live births. The decline in ACCM was greater among children aged 6–23 months (relative reduction of 36%), compared to children aged 24–59 months (relative reduction of 12%). Cox regression indicated that household ownership of at least one ITN reduced the risk of mortality by 24% among children under five (risk ratio = 0.76, 95% CI 0.64–0.90). Contextual factor analysis revealed marginal improvements in socioeconomic indicators and other health interventions. Conclusions Given the patterns of the coverage of malaria control interventions, patterns in ACCM by province, and marginal improvements in contextual factors, the authors conclude that the malaria control interventions have plausibly contributed to the decrease in ACCM in the Democratic Republic of Congo from 2005 to 2014.

description: Prior studies suggest that post-traumatic stress disorder (PTSD) is associated with elevated cardiovascular disease (CVD) risk, but effects of duration and remission of PTSD symptoms have rarely been evaluated.

We examined the association of time-updated PTSD symptom severity, remission and duration with incident CVD risk (552 confirmed myocardial infarctions or strokes) over 20 years in 49 859 women in the Nurses’ Health Study II. Among women who reported trauma on the Brief Trauma Questionnaire, PTSD symptoms, assessed by a screener, were classified by symptom severity and chronicity: (a) no symptoms, (b) 1–3 ongoing, (c) 4–5 ongoing, (d) 6–7 ongoing, (e) 1–3 remitted, (f) 4–7 remitted symptoms. Inverse probability weighting was used to estimate marginal structural logistic regression models, adjusting for time-varying and time-invariant confounders.

Compared with women with no trauma exposure, women with trauma/no PTSD [odds ratio (OR) 1.30, 95% confidence interval (CI) 1.03–1.65] and women with trauma/6–7 symptoms (OR 1.69, 95% CI 1.08–2.63) had elevated risk of CVD; women with remitted symptoms did not have elevated CVD risk. Among women exposed to trauma, every 5 additional years of PTSD symptomology was associated with 9% higher CVD incidence compared with women with trauma/no PTSD.

The findings suggest that alleviating PTSD symptoms shortly after onset may attenuate CVD risk.

description: This part is a continuation of the Part I where we built resolutions of identity for certain non-Hermitian Hamiltonians constructed of biorthogonal sets of their eigen- and associated functions for the spectral problem defined on entire axis. Non-Hermitian Hamiltonians under consideration are taken with continuous spectrum and the following cases are examined: an exceptional point of arbitrary multiplicity situated on a boundary of continuous spectrum and an exceptional point situated inside of continuous spectrum. In the present work the rigorous proofs are given for the resolutions of identity in both cases.
title: Micellar- and polymer-enhanced ultrafiltration for heavy metal and sulfate removal from aqueous solutions
Creators: name: Lin, Weiyun
Publisher: name: Lin, Weiyun
Year: 2020

description: Micellar-enhanced ultrafiltration (MEUF) and polymer-enhanced ultrafiltration (PEUF) show potential as promising techniques to remove dissolved ions from wastewater, but they remain inadequately understood. In this thesis, the MEUF removal of copper, nickel, and cobalt ions from aqueous solutions was investigated. The effect of surfactant-to-metal (S/M) ratio and pH on MEUF performance (i.e., metal rejection rate and permeate flux) were examined to obtain the preferred operational conditions. A resampling-based artificial neural network (ANN) modeling was proposed as a promising tool to predict the MEUF performance and to reveal the importance of process parameters. The model-predicted values showed good agreement with experimental data (R² > 0.99). S/M ratio and pH had relatively greater contributions to the system performance, whereas sampling time contributed less. A high MEUF efficiency (Rejection > 99%) was achieved.
 To optimize the system performance and to observe the interactions among operational parameters, the statistical-based response surface methodology (RSM) was used to overcome the drawbacks of the commonly used one-factor-at-a-time method. The thesis is the first study to use an RSM method based on a Box-Behnken design to examine nickel ion removal in a MEUF system while combine with an ANN model. The generated RSM models described the relationship between each performance indicator (nickel rejection rate or permeate flux) and process variables (transmembrane pressure, feed nickel concentration, feed surfactant concentration, and membrane molecular weight cut-off (MWCO) of the membrane). Both RSM and ANN methods adequately described the performance indicators within the examined ranges of the process variables.
 Next, the thesis targets on sulfate ions, a dissolved anion of increasing concern but not tackled in the MEUF/PEUF field. The thesis is the first study to use MEUF and PEUF to remove sulfate ions as the target component from aqueous solutions. It is also the first to examine the adsorption mechanism of sulfate to surfactant/polymer in such systems. Both MEUF and PEUF were found technically viable to remove sulfate from aqueous streams, with the highest rejection rate (Rejection > 99%) found in dilute sulfate solutions. Further, adsorption equilibrium and kinetics studies show that Freundlich isotherm and pseudo-second-order kinetics can describe the adsorption process.
 This thesis adds knowledge to the existing MEUF/PEUF techniques by improving system operation, conducting system optimization, and exploring new components (i.e., sulfate ions) that can be removed. It also provides treatment information and potentially facilitates reservoir souring control and mining wastewater treatment.
The role of B7-H4 in islet transplantation

Publisher: name: University of British Columbia

description: Allogeneic pancreatic islet transplantation has the potential to cure type 1 diabetes. One of the barriers to islet transplantation is the alloreactive T-cell response between donors and recipients. Co-stimulatory molecules, which play a major role in regulation of the immune response during graft rejection, may be used to inhibit allograft destruction and generate tolerance. B7-H4 is one such member in the co-stimulatory family to negatively regulate T-cell responses. However, its role in the transplantation field has not been investigated. The aim of this study is to determine the function of B7-H4 in modulating an alloreactive immune response and its signal transduction pathway. The role of B7-H4 in alloimmunity was assessed using a fully major histocompatibility complex mismatched mouse islet transplantation model. Expression of B7-H4 by a recombinant adenovirus in donor allograft islets significantly improved their survival. Moreover, prolonged graft survival was observed in the absence of immunosuppression after secondary transplant, suggesting development of donor specific tolerance. B7-H4 controlled alloreactive immune response by limiting infiltrating cells and increasing Foxp3 expressing cells in the local graft. B7-H4 treatment significantly modulated naturally occurring and inducible regulatory T cells in the periphery and generated hyporesponsiveness to alloantigen. Study of the mechanism by which B7-H4 inhibits T cells revealed interference with activation of ERK, JNK, and AKT, but not through CD3/TCR proximal signal ZAP70 or LCK. This study advances our understanding of the role of the novel co-inhibitory molecule B7-H4 in alloimmune responses. Local expression of B7-H4 prolongs islet allograft survival and generates donor-specific tolerance in vivo, suggesting translational potential for use in reducing immune injury during islet transplantation.

description: Articulating Concrete Blocks (ACBs) have been a popular choice for high performance erosion control applications and shoreline revetments for well over 35 years and continue to grow in popularity. Estimates point to over 200 dam embankments and emergency spillways having been armored with ACBs in the past 30 years. As a result of these applications, as well as the thousands of other projects not specific to dams, much has been learned from a theoretical as well as practical application standpoint of properly utilizing ACBs in the field. This presentation will provide information concerning ACB Factor of Safety (FOS) determination, briefly review the ACB testing protocols and data analysis, and discuss the practical uses and limitations of ACB applications. New installation techniques that show promise for improving ACB performance will be discussed. ACBs are a proven cost effective erosion countermeasure, however experience and attention to detail during the design and installation of systems is of paramount importance for expected performance.

description: Masked hypertension is associated with increased risk for cardiovascular disease. Identifying modifiable risk factors for masked hypertension could provide approaches to reduce its prevalence. Life’s Simple 7 is a measure of cardiovascular health developed by the American Heart Association that includes body mass index, physical activity, diet, cigarette smoking, blood pressure (BP), cholesterol, and glucose. We examined the association between cardiovascular health and masked daytime hypertension in the Jackson Heart Study, an exclusively African American cohort. Life’s Simple 7 factors were assessed during a study visit and categorized as poor, intermediate, or ideal. Ambulatory BP monitoring was performed after the study visit. Using BP measured between 10:00 AM and 8:00 PM on ambulatory BP monitoring, masked daytime hypertension was defined as mean clinic systolic BP/diastolic BP <140/90 mm Hg and mean daytime systolic BP/diastolic BP ≥135/85 mm Hg. Among the 758 participants with systolic BP/diastolic BP <140/90 mm Hg, 30.5% had masked daytime hypertension. The multivariable-adjusted prevalence ratios for masked daytime hypertension comparing participants with 2, 3, and ≥4 versus ≤1 ideal Life’s Simple 7 factors were 0.99 (95% confidence interval [CI], 0.74–1.33), 0.77 (95% CI, 0.57–1.03), and 0.51 (95% CI, 0.33–0.79), respectively. Masked daytime hypertension was less common among participants with ideal versus poor levels of physical activity (ratio, 0.74; 95% CI, 0.56–1.00), ideal or intermediate levels pooled together versus poor diet (prevalence ratio, 0.73; 95% CI, 0.58–0.91), ideal versus poor levels of cigarette smoking (prevalence ratio, 0.61; 95% CI, 0.46–0.82), and ideal versus intermediate levels of clinic BP (prevalence ratio, 0.28, 95% CI, 0.16–0.48). Better cardiovascular health is associated with a lower preva lence of masked hypertension.

description: We consider a mass-asymmetric polarized Fermi system in the presence of Hartree-Fock (HF) potentials. We concentrate on the BCS regime with various interaction strengths and numerically obtain the allowed values of the chemical and HF potentials, as well as the mass ratio. The functional dependence of the heat conductivity of the N-SF interface on relevant physical parameters, namely the temperature, the mass ratio, and the interaction strength, is obtained. In particular, we show that the interface conductivity starts to drop with decreasing temperature at the temperature, $T_{\text{m}}$, where the mean kinetic energy of the particles is just sufficient to overcome the SF gap. We obtain $T_{\text{m}}$ as a function of the mass ratio and the interaction strength. The variation of the heat conductivity, at fixed temperature, with the HF potentials and the imbalance chemical potential is also obtained. Finally, because the range of relevant temperatures increases for larger values of the mass ratio, we consider the $^6\text{Li}$-$^{40}\text{K}$ mixture separately by taking the temperature dependence of the pair potential into account.

description: Background: Clinical guidelines recommend using predicted atherosclerotic cardiovascular disease (ASCVD) risk to inform treatment decisions. The objective was to compare the contribution of changes in modifiable risk factors versus aging to the development of high 10‐year predicted ASCVD risk.

Methods and Results: A prospective follow‐up was done of the Jackson Heart Study, an exclusively black cohort at visit 1 (2000–2004) and visit 3 (2009–2012). Analyses included 1115 black participants without high 10‐year predicted ASCVD risk (<7.5%), hypertension, diabetes mellitus, or ASCVD at visit 1. We used the Pooled Cohort equations to calculate the incidence of high (≥7.5%) 10‐year predicted ASCVD risk at visit 3. We recalculated the percentage with high 10‐year predicted ASCVD risk at visit 3 assuming each risk factor (age, systolic blood pressure, antihypertensive medication use, diabetes mellitus, smoking, total and high‐density lipoprotein cholesterol), one at a time, did not change from visit 1. The mean age at visit 1 was 45.2±9.5 years. Overall, 30.9% (95% CI 28.3–33.4%) of participants developed high 10‐year predicted ASCVD risk. Aging accounted for 59.7% (95% CI 54.2–65.1%) of the development of high 10‐year predicted ASCVD risk compared with 32.8% (95% CI 27.0–38.2%) for increases in systolic blood pressure or antihypertensive medication initiation and 12.8% (95% CI 9.6–16.5%) for incident diabetes mellitus. Among participants <50 years, the contribution of increases in systolic blood pressure or antihypertensive medication initiation was similar to aging.

Conclusions: Increases in systolic blood pressure and antihypertensive medication initiation are major contributors to the development of high 10‐year predicted ASCVD risk in blacks, particularly among younger adults.

description: We use a large sample of upper limits and accurate estimates of supermassive black holes masses coupled with libraries of host galaxy velocity dispersions, rotational velocities and photometric parameters extracted from Sloan Digital Sky Survey i-band images to establish correlations between the SMBH and host galaxy parameters. We test whether the mass of the black hole, MBH, is fundamentally driven by either local or global galaxy properties. We explore correlations between MBH and stellar velocity dispersion sigma, bulge luminosity, bulge mass Sersic index, bulge mean effective surface brightness, luminosity of the galaxy, galaxy stellar mass, maximum circular velocity Vc, galaxy dynamical and effective masses. We verify the tightness of the MBH-sigma relation and find that correlations with other galaxy parameters do not yield tighter trends. We do not find differences in the MBH-sigma relation of barred and unbarred galaxies. The MBH-sigma relation of pseudo-bulges is also coarser and has a different slope than that involving classical bulges. The MBH-bulge mass is not as tight as the MBH-sigma relation, despite the bulge mass proving to be a better proxy of MBH than bulge luminosity. We find a rather poor correlation between MBH and Sersic index suggesting that MBH is not related to the bulge light concentration. The correlations between MBH and galaxy luminosity or mass are not a marked improvement over the MBH sigma relation. If Vc is a proxy for the dark matter halo mass, the large scatter of the MBH-Vc relation then suggests that MBH is more coupled to the baryonic rather than the dark matter. We have tested the need for a third parameter in the MBH scaling relations, through various linear correlations with bulge and galaxy parameters, only to confirm that the fundamental plane of the SMBH is mainly driven by sigma, with a small tilt due to the effective radius.

description: Background: Abnormal diurnal blood pressure (BP), including nondipping patterns, assessed using ambulatory BP monitoring, have been associated with increased cardiovascular risk among white and Asian adults. We examined the associations of BP dipping patterns (dipping, nondipping, and reverse dipping) with cardiovascular target organ damage (left ventricular mass index and left ventricular hypertrophy), among participants from the Jackson Heart Study, an exclusively black population–based cohort.

Methods and Results: Analyses included 1015 participants who completed ambulatory BP monitoring and had echocardiography data from the baseline visit. Participants were categorized based on the nighttime to daytime systolic BP ratio into 3 patterns: dipping pattern (≤0.90), nondipping pattern (>0.90 to ≤1.00), and reverse dipping pattern (>1.00). The prevalence of dipping, nondipping, and reverse dipping patterns was 33.6%, 48.2%, and 18.2%, respectively. In a fully adjusted model, which included antihypertensive medication use and clinic and daytime systolic BP, the mean differences in left ventricular mass index between reverse dipping pattern versus dipping pattern was 8.3±2.1 g/m2 (P<0.001) and between nondipping pattern versus dipping pattern was −1.0±1.6 g/m2 (P=0.536). Compared with participants with a dipping pattern, the prevalence ratio for having left ventricular hypertrophy was 1.65 (95% CI, 1.05–2.58) and 0.96 (95% CI, 0.63–1.97) for those with a reverse dipping pattern and nondipping pattern, respectively.

Conclusions: In this population‐based study of blacks, a reverse dipping pattern was associated with increased left ventricular mass index and a higher prevalence of left ventricular hypertrophy. Identification of a reverse dipping pattern on ambulatory BP monitoring may help identify black at increased risk for cardiovascular target organ damage.

description: We developed transmon qubits based on epitaxial tunnel junctions and interdigitated capacitors. This multileveled qubit, patterned by use of all-optical lithography, is a step towards scalable qubits with a high integration density. The relaxation time T1 is .72-.86mu sec and the ensemble dephasing time T2 is slightly larger than T1. The dephasing time T2 (1.36mu sec) is nearly energy-relaxation-limited. Qubit spectroscopy yields weaker level splitting than observed in qubits with amorphous barriers in equivalent-size junctions. The qubit's inferred microwave loss closely matches the weighted losses of the individual elements (junction, wiring dielectric, and interdigitated capacitor), determined by independent resonator measurements.

description: The North American Softwood Lumber market has been extremely dynamic over the past 30 years with significant growth and contraction over this time. This thesis presents a methodical examination of this market and its development over this period. This research provides an in-depth overview of the evolution of this conflict as well as a theoretical explanation of the various trade instruments used. It then explores the welfare implications of these managed trade regimes by first estimating supply and demand elasticities then simulating the hypothetical effects of each regime using the estimated elasticities in combination with reference prices and quantities for the U.S. and Canada. This paper finds that the new softwood lumber agreements economic implications are far more complex than its predecessors and may lead to further price volatility. This paper also reinforces the view that managed trade agreements are rarely favorable to all parties involved but, through careful identification of priorities, potential disruptions can be minimized.

description: Presented at the Protections 2016: 2nd international seminar on dam protection against overtopping: concrete dams, embankment dams, levees, tailings dams held on 7th-9th September, 2016, at Colorado State University in Fort Collins, Colorado, USA. The increasing demand for dam and levee safety and flood protection has motivated new research and advancements and a greater need for cost-effective measures in overtopping protection as a solution for overtopping concerns at levees and dams. This seminar will bring together leading experts from practice, research, development, and implementation for two days of knowledge exchange followed by a technical tour of the Colorado State University Hydraulic Laboratory with overtopping flume and wave simulator. This seminar will focus on: Critical issues related to levees and dams; New developments and advanced tools; Overtopping protection systems; System design and performance; Applications and innovative solutions; Case histories of overtopping events; Physical modeling techniques and recent studies; and Numerical modeling methods.
description: Includes bibliographical references.
description: Case studies that focus on exceedance of the design flood event and the resulting overtopping conditions may be used to provide cost-effective analysis of overtopping protection systems. For this case study, conditions of levee overtopping are evaluated for the Probable Maximum Flood (PMF), with a two dimensional flow model (FLO-2D) used to represent the flood event in a relatively flat area susceptible to flash flooding. The model calculates the duration of overtopping and the resulting flood depths and velocities. The model outputs are utilized to evaluate the effectiveness of riprap as potential overtopping protection.

description: Based on reflection symmetry in the reaction plane, it is shown that measuring the transverse spin-transfer coefficient $K_{yy}$ in the $\bar{K}N \to KΞ$ reaction directly determines the parity of the produced cascade hyperon in a model-independent way as $π_Ξ=K_{yy}$, where $π_Ξ=\pm 1$ is the parity. This result based on Bohr's theorem provides a completely general, universal relationship that applies to the entire hyperon spectrum. A similar expression is obtained for the photoreaction $γN \to K K Ξ$ by measuring both the double-polarization observable $K_{yy}$ and the photon-beam asymmetry $Σ$. Regarding the feasibility of such experiments, it is pointed out that the self-analyzing property of the $Ξ$'s can be invoked, thus requiring only a polarized nucleon target.

A stadium of small things: collecting contemporary Canadian fiction

description: Bibliography: p. 228-240
description: This dissertation examines the figure of the collector and the trope of collecting in recent Canadian fiction in order to propose new theoretical and thematic strategies of reading critically within the field. "A Stadium of Small Things" takes the form of a collection itself; it gathers together dreams, memoir, architecture, archives, cultural studies, and literary theory in its reconsideration of the desires of fictional and real Can Lit collectors, and the narrative possibilities born of their collections as objects, representations, and allusions. Taking its major theoretical lead from Walter Benjamin's The Arcades Project, the thesis begins by proposing a theory of collecting as a means of constructing, recreating, or continuing narratives that aim to resist their own conclusion and closure. It reads objects for the subjectivity they acquire as part of collections, and it treats those collections, variously, as presence, absence, and arcade. Collections, though, are examined not merely as thematic constructions, but as structural and narratological strategies functioning in distinctive ways within several recent Canadian fictions as both products and ongoing processes of reading and writing. This project finds its title and its inspiration in Michael Ondaatje's attempt to collect his father's past in the memoir Running in the Family, and it undertakes critical readings of the collectors and collections in fictions by Robert Kroetsch, Timothy Findley, Thomas King, Alice Munro, Alissa York, Margaret Laurence, Dionne Brand, Timothy Taylor, Jane Urquhart, Kyo Maclear, Robert Majzels, and C. S. Richardson. It argues, ultimately, that Can Lit collections-both in and as narratives-can be endlessly reordered and reinvented

description: We study the regularity properties of the Hausdorff distance between spectra of continuous Harper-like operators. As a special case we obtain Hölder continuity of this Hausdorff distance with respect to the intensity of the magnetic field for a large class of magnetic elliptic (pseudo)differential operators with long range magnetic fields.

description: Background:
As many as 12% of acute coronary syndrome (ACS) patients screen positive for post-traumatic stress disorder (PTSD) symptoms due to their cardiac event, and emergency department (ED) factors such as overcrowding have been associated with risk for PTSD. We tested the association of patients’ perceptions of their proximity to a critically ill patient during ED evaluation for ACS with development of posttraumatic stress symptoms (PSS) in the month after hospital discharge.

Methods:
Participants were enrolled in the REactions to Acute Care and Hospitalization (REACH) study during evaluation for ACS in an urban ED. Participants reported whether they perceived a patient near them was close to death. They also reported their current fear, concern they may die, perceived control, and feelings of vulnerability on an Emergency Room Perceptions questionnaire. One month later, participants reported on PTSD symptoms specific to the cardiac event and ED hospitalization.

Results:
Of 763 participants, 12% reported perceiving a nearby patient was likely to die. In a multivariate linear regression model [F(9757) = 19.69, p < .001, R2 adjusted = .18] with adjustment for age, sex, GRACE cardiac risk score, discharge ACS diagnosis, Charlson comorbidity index, objective ED crowding, and depression symptoms at baseline, perception of a nearby patients’ likely death was associated with a 2.33 point (95% CI, 0.60–4.61) increase in 1 month PTSD score. A post hoc mediation analysis with personal threat perceptions [F(10,756) = 25.28, p < .001, R2 adjusted = .24] showed increased personal threat perceptions during the ED visit, B = 0.71 points on the PCL per point on the personal threat perception questionnaire, β = 0.27, p = .001, fully mediated association of participants’ perceptions of nearby patients’ likely death with 1-month PTSD score (after adjustment for ED threat perceptions,) B = 0.89 (95% CI, −1.33 to 3.12), β = 0.03, p = .43, accounting for 62% of the adjusted effect and causing the main effect to become statistically nonsignificant.

Conclusions:
We found patients who perceived a nearby patient was likely to die had significantly greater PTSD symptoms at 1 month. Awareness of this association may be helpful for designing ED patient management procedures to identify and treat patients with an eye to post-ACS psychological care.
Finite element simulation of hydraulic fracturing in unconsolidated sands

description: Fluid injection into reservoirs; such as waste disposal, steam or water flooding and well testing, is a common practice in oil and gas industry. The injection of large volumes of fluid into an unconsolidated sands reservoir can result in significant changes to the in-situ stress distributions which may lead to the hydraulic fractures initiation and propagation. Hydraulic fracturing can be broadly defined as a process by which a fracture initiates and propagates due to hydraulic loading (i.e., pressure) applied by a fluid inside the fracture[l]. Although hydraulic fracturing in hard rock has been comprehensively studied both experimentally and numerically, some fundamental mechanisms of hydraulic fracturing in unconsolidated formation have not been well understood. The hydraulic fracture in unconsolidated sand reservoir can be represented as an anisotropic area of dilation zone or a net of micro-cracks, inside which the formation has low effective stresses and high hydraulic conductivity values. In this thesis, w present a 3D finite element model for simulating the hydraulic fracture initiation and propagation in unconsolidated sands reservoir due to large volumes of fluid injection at high injection rate. To simulate this strong anisotropy in mechanical and hydraulic behaviour induced by fluid injection, a poro-elasto-plastic constitutive model together with a strain-induced anisotropic permeability model are formulated and implemented into a 3D finite element simulator, which is used to match the field injection data. Several case studies, which include the field produced water re-injection into deep unconsolidated formation and well testing in oil sands formation, are conducted using the developed finite element model. The bottom-hole-pressures predicted by the developed finite element codes are used to history match the field bottom-hole-pressures. The numerical calculations clearly show that the presented numerical model can capture the physical mechanism of hydraulic fracture initiation and propagation in unconsolidated sand formation and matches the field pressure versus time curve very well.
