Obliquely rotating pulsars: screening of the inductive electric field

description: Pulsar electrodynamics has been built up by taking ingredients from two models, the vacuum-dipole model, which ignores the magnetosphere but includes the inductive electric field due to the obliquely rotating magnetic dipole, and the corotating-magnetosphere model, which neglects the vacuum inductive electric field and assumes a corotating magnetosphere. We argue that the inductive field can be neglected only if it is screened by a current, ${\bi J}_{\rm sc}$, which we calculate for a rigidly rotating magnetosphere. Screening of the parallel component of the inductive field can be effective, but the perpendicular component cannot be screened in a pulsar magnetosphere. The incompletely screened inductive electric field has not been included in any model for a pulsar magnetosphere, and taking it into account has important implications. One effect is that it implies that the magnetosphere cannot be corotating, and we suggest that drift relative to corotation offers a natural explanation for the drifting of subpulses. A second effect is that this screening of the parallel inductive electric field must break down in the outer magnetosphere, and this offers a natural explanation for the acceleration of the electrons that produce pulsed gamma-ray emission.

description: The problem is to calculate a simple zero of a nonlinear function f. We consider rational iterations without memory which use two evaluations of f or its derivatives. It is shown that the optimal order is 2. This settles a conjecture of Kung and Traub that an iteration using n evaluations without memory is of order at most 2ⁿ⁻¹, for the case n=2. Furthermore we show that any rational two-evaluation iteration of optimal order must use either two evaluations of f or one evaluation of f and one of f'. From this result we completely settle the question of the optimal efficiency, in our efficiency measure, for any two-evaluation iteration without memory. Depending on the relative cost of evaluating f and f', the optimal efficiency is achieved by either Newton iteration or the iteration ᴪ.

description: The behavior of the vector recurrence y_(n + 1) = My_n + w_(n + 1) is studied under very weak assumptions. Let λ(M) denote the spectral radius of M and let λ(M) ≥ 1. Then if the w_n are bounded in norm and a certain subspace hypothesis holds, the root order of the y_n is shown to be λ(M). If one additional hypothesis on the dimension of the principal Jordan blocks of M holds, then the quotient order of the y_n is also λ(M). The behavior of the homogeneous recurrence is studied for all values of λ(M). These results are applied to the analysis of (1) Nonlinear iteration with application to iteration with memory and to parallel iteration algorithms. (2) Order and efficiency of composite iteration.

description: Background: Due to the COVID-19 pandemic, an extensive reorganisation of healthcare resources was necessary-with a particular impact on surgical care across all disciplines. However, the direct and indirect consequences of this redistribution of resources on surgical therapy and care are largely unknown. Methods: We analysed our prospectively collected standardised digital quality management document for all surgical cases in 2020 and compared them to the years 2018 and 2019. Periods with high COVID-19 burdens were compared with the reference periods in 2018 and 2019. Results: From 2018 to 2020, 10,723 patients underwent surgical treatment at our centres. We observed a decrease in treated patients and a change in the overall patient health status. Patient age and length of hospital stay increased during the COVID-19 pandemic (p = 0.004 and p = 0.002). Furthermore, the distribution of indications for surgical treatment changed in favour of oncological cases and less elective cases such as hernia repairs (p < 0.001). Postoperative thromboembolic and pulmonary complications increased slightly during the COVID-19 pandemic. There were slight differences for postoperative overall complications according to Clavien-Dindo, with a significant increase of postoperative mortality (p = 0.01). Conclusion: During the COVID-19 pandemic we did not see an increase in the occurrence, or the severity of postoperative complications. Despite a slightly higher rate of mortality and specific complications being more prevalent, the biggest change was in indication for surgery, resulting in a higher proportion of older and sicker patients with corresponding comorbidities. Further research is warranted to analyse how this changed demographic will influence long-term patient care.

description: The objectives of this study are: 1) to evaluate the best band combinations to estimate soil salinity with each crop type; 2) to compare regression kriging and cokriging techniques when applied to LANDSAT images to generate accurate soil salinity maps; and to compare the performance of different crop types: alfalfa, cantaloupe, corn, and wheat as indicators of soil salinity; and. This study was conducted in an area in the southern part of the Arkansas River Basin in Colorado. Six LANDSAT images acquired during the years: 2000, 2001, 2003, 2004, 2005, and 2006 in conjunction with field data were used to estimate soil salinity in the study area. The optimal subset of band combinations from LANDSAT images that correlates best with the soil salinity data was selected. Regression kriging and cokring were applied to 2,915 soil salinity data points collected in alfalfa, cantaloupe, corn, and wheat fields in conjunction with the selected subset band combinations from the LANDSAT images. Ordinary Least Squares (OLS) was used to regress the correlated band combinations to generate a soil salinity surface. The residuals of the OLS model were kriged and combined with the soil salinity surface generated using the OLS model to produce the final regression kriging soil salinity surface. The same LANDSAT band combinations used with the regression kriging technique were used as secondary data variables with the cokriging technique, while soil salinity data was used as a primary variable. The results show that the best band combinations for estimating soil salinity with different crops are as follows: alfalfa (red, near infrared, and NDVI); cantaloupe (green, and near infrared); corn (near infrared, thermal, and NDVI); and wheat (blue and thermal). The regression kriging technique performed better than the cokriging technique since it was able to capture most of the small variations in soil salinity. Corn fields performed the best and alfalfa fields performed the least. Wheat comes in the second place and cantaloupe comes in the third place.

description: Mathematics anxiety (MA) is an academic anxiety related to doing, learning and testing mathematics. MA can negatively affect mathematics performance, motivation and math-heavy science and technology-related career choices. Previous data suggest that subjective perceptions and interpretations of students are key in the genesis of MA. Here, based on expectancy-value and control- value theory, we aimed to identify potential, theoretically based subjective factors likely key to under- standing MA. We analysed data from 151 745 fifteen-year-old children from 65 ‘countries and economies' from the PISA 2012 dataset. Subjective self-perceptions had a stronger relationship with MA than math achievement. We found that higher MA was associated with lower perceived control over math activities and lower subjective expectation of success. Surprisingly, children with higher subjective valuation of math had higher MA for similar levels of subjective control and success expectancy in math. Results offer an improved understanding of potential antecedents of MA and suggest that effective interventions could be based on gradual confidence building in math. These could primarily draw on a deeper understanding of the subject improving subjective success expectancy and feeling of control over math activities. Cultural variation in findings is discussed.

Different dimensionality trends in the Landau damping of magnons in iron, cobalt and nickel: time dependent density functional study

description: We study the Landau damping of ferromagnetic magnons in Fe, Co, and Ni as the dimensionality of the system is reduced from three to two. We resort to the \textit{ab initio} linear response time dependent density functional theory in the adiabatic local spin density approximation. The numerical scheme is based on the Korringa-Kohn-Rostoker Green's function method. The key points of the theoretical approach and the implementation are discussed. We investigate the transition metals in three different forms: bulk phases, free-standing thin films and thin films supported on a nonmagnetic substrate. We demonstrate that the dimensionality trends in Fe and Ni are opposite: in Fe the transition from bulk bcc crystal to Fe/Cu(100) film reduces the damping whereas in Ni/Cu(100) film the attenuation increases compared to bulk fcc Ni. In Co, the strength of the damping depends relatively weakly on the sample dimensionality. We explain the difference in the trends on the basis of the underlying electronic structure. The influence of the substrate on the spin-wave damping is analyzed by employing Landau maps representing wave-vector resolved spectral density of the Stoner excitations.

description: Diffusely infiltrating gliomas, of which glioblastoma (GBM) is most common, are highly aggressive brain tumors with dismal outcomes. Application of the Cancer Stem Cell (CSC) hypothesis to glioma led to the discovery of Brain Tumor Stem Cells (BTSCs) and a direct link to Neural Stem Cells (NSCs). In this thesis I begin by trying to identify characteristics that distinguish BTSCs from NSCs. I cultured cells isolated from GBMs, using the neurosphere culture system, in order to understand their growth requirements. GBM BTSCs proliferated in the absence of exogenous mitogenic stimulation and gave rise to multipotent GBM spheres that were capable of self-renewal. Epidermal growth factor and fibroblast growth factor-2 enhanced GBM BTSC survival and proliferation. Implantation of exogenous mitogen independent GBM BTSCs led to the formation of highly invasive intracranial tumors in immunocompromised mice. Thus, exogenous mitogen independence is one characteristic that distinguishes GBM BTSCs from NSCs. I then ask whether BTSCs can be isolated from other gliomas, specifically oligodendroglioma. Investigating the biology of oligodendroglioma, and its characteristic combined deletion of chromosomal arms 1 p and 19q, has been hampered by the lack of cell lines that harbor these traits. Cells from anaplastic oligodendrogliomas cultured in serum-free conditions, followed by serial propagation and expansion, led to the establishment of permanent cell lines that maintained the genetic signature of the parent tumors. Furthermore, these oligodendroglioma cells displayed features of BTSCs in vitro. These lines may be important tools for understanding the biology of oligodendroglioma and the function of their defining genetic traits. Finally, I employed the neurosphere culture system in order to generate 70 cell lines that collectively comprise a cellular model system of GBM. This robust model system harbors characteristic genetic abnormalities of GBM that permit sub-grouping of the cell lines. Importantly, this system recapitulates the heterogeneity of GBM and facilitates both in vitro and in vivo studies of phenotypic and molecular sub-groups. By coupling cell line generation with molecular characteristics and patient outcome, the model system has direct clinical relevance. In sum, the results demonstrate that glioma heterogeneity is evident in BTSCs isolated from individual tumors. This unique experimental system will permit elucidation of mechanisms that underlie glioma BTSC biology together with preclinical studies that evaluate novel therapeutic strategies.

description: We fulfill the detailed analysis of coupling the charged bosonic higher spin fields to external constant electromagnetic field in first order in external field strength. Cubic interaction vertex of arbitrary massive and massless bosonic higher spin fields with external field is found. Construction is based on deformation of free Lagrangian and free gauge transformations by terms linear in electromagnetic field strength. In massive case a formulation with Stueckelberg fields is used. We begin with most general form of deformations for Lagrangian and gauge transformations, admissible by Lorentz covariance and gauge invariance and containing some number of arbitrary coefficients, and require the gauge invariance of the deformed theory in first order in strength. It yields the equations for the coefficients which are exactly solved. As a result, the complete interacting Lagrangian of arbitrary bosonic higher spin fields with constant electromagnetic field in first order in electromagnetic strength is obtained. Causality of massive spin-2 and spin-3 fields propagation in the corresponding electromagnetic background is proved.

description: The guanine-rich RNA sequence binding factor 1 (GRSF1) is an RNA-binding protein of the heterogenous nuclear ribonucleoprotein H/F (hnRNP H/F) family that binds to guanine-rich RNA sequences forming G-quadruplex structures. In mice and humans there are single copy GRSF1 genes, but multiple transcripts have been reported. GRSF1 has been implicated in a number of physiological processes (e.g. embryogenesis, erythropoiesis, redox homeostasis, RNA metabolism) but also in the pathogenesis of viral infections and hyperproliferative diseases. These postulated biological functions of GRSF1 originate from in vitro studies rather than complex in vivo systems. To assess the in vivo relevance of these findings, we created systemic Grsf1(-/-) knockout mice lacking exons 4 and 5 of the Grsf1 gene and compared the basic functional characteristics of these animals with those of wildtype controls. We found that Grsf1-deficient mice are viable, reproduce normally and have fully functional hematopoietic systems. Up to an age of 15 weeks they develop normally but when male individuals grow older, they gain significantly less body weight than wildtype controls in a gender-specific manner. Profiling Grsf1 mRNA expression in different mouse tissues we observed high concentrations in testis. Comparison of the testicular transcriptomes of Grsf1(-/-) mice and wildtype controls confirmed near complete knock-out of Grsf1 but otherwise subtle differences in transcript regulations. Comparative testicular proteome analyses suggested perturbed mitochondrial respiration in Grsf1(-/-) mice which may be related to compromised expression of complex I proteins. Here we present, for the first time, an in vivo complete Grsf1 knock-out mouse with comprehensive physiological, transcriptomic and proteomic characterization to improve our understanding of the GRSF1 beyond in vitro cell culture models.
The road away from home : policy and power in post-Katrina New Orleans
Creators: name: Rosenman, Emily
Publisher: name: University of British Columbia
Year: 2011

description: In this thesis I explore several intersections of hurricane recovery, urban planning, housing assistance, and neighborhood organizing in post-Katrina New Orleans. These intersections include the mobilization of particular kinds of evidence in redevelopment planning, the construction of “community” and “neighborhood” in the aftermath of disaster, and the changing geographical scale of community development in a post-disaster environment. Hurricane Katrina has inspired a huge amount of research; much of which has been written from either a policy or hazards/disaster perspective. I argue in Chapter 2 that the disaster literature on Hurricane Katrina can benefit from engagement with literature on urban governance and the politics of civic engagement. Similarly, I propose in Chapter 3 that economic analyses of pre-and post-Katrina data must be contextualized by the post-Katrina politics and social realities of New Orleans. In this chapter, I explore the effects of depoliticizing the issue of affordable housing in New Orleans. In engendering public uncertainty about the reliability of housing data, powerful landlords and politicians avoided a debate on housing access and instead focused legislative attention on a seemingly counterintuitive question: is there too much affordable housing in New Orleans? In this chapter, I find that a preoccupation with questions about the accuracy of housing data became a tool to shut down political debate and to present subsidized housing as a nuisance to New Orleans neighborhoods and, more threateningly, to the city’s housing market as a whole. Through in-depth interviews and observations of public meetings, Chapter 4 explores neighborhood-scale participation in the governance of post-Katrina New Orleans. In this chapter I analyze the manifestations of civic involvement in three hurricane-damaged neighborhoods and find that civic participation inside or outside of formal political structures yields different results for New Orleans’ neighborhoods, and that some avenues of participation are more easily visible than others. Finally, this thesis concludes with some reflections on persisting inequalities in the post-hurricane recovery process and the New Orleans’ upcoming plans to standardize neighborhood participation in urban planning.

description: We use the "magnetic tweezers" technique to reveal the structural transitions that DNA undergoes in the force-torsion space. In particular, we focus on regions corresponding to negative supercoiling. These regions are characterized by the formation of so-called denaturation bubbles, which have an essential role in the replication and transcription of DNA. We experimentally map the region of the force-torsion space where the denaturation takes place. We observe that large fluctuations in DNA extension occur at one of the boundaries of this region, i.e., when the formation of denaturation bubbles and of plectonemes are competing. To describe the experiments, we introduce a suitable extension of the classical model. The model correctly describes the position of the denaturation regions, the transition boundaries, and the measured values of the DNA extension fluctuations.

Healthy human volunteers were assessed twice, once after acute (single-dose), and once after prolonged (week-long) daily administration of the SSRI citalopram or placebo. Using computational modelling, we show that prolonged boosting of serotonin enhances learning from punishment and reduces learning from reward. This valence-dependent learning asymmetry increases subjects' tendency to avoid actions as a function of cumulative failure without leading to detrimental, or advantageous, outcomes. By contrast, no significant modulation of learning was observed following acute SSRI administration. However, differences between the effects of acute and prolonged administration were not significant. Overall, these findings may help explain how serotonergic agents impact on mood disorders.

description: As prevention of disasters concerning flooding in coastal urban area, this study has developed the real time monitoring system aimed at the On-cheon stream in Busan. The basis of this study was a selection of various geological data based on the numerical map and computation of hydrologic GIS data. Thiessen polygon method was used to analyze rainfall on this site. And regression equation of 6th degree and Huff's Type II was used for investigating time-distribution of rainfall. To estimate warning standard rainfall and flood discharge, risk depth was selected on Sebyeong bridge site. Flood depth and threshold runoff considering the effect of tidal water level was estimated for hydraulic analysis using HEC-RAS and urban flash flood rainfall were evaluated using PCSWMM 2002. Consequently, this study estimated warning standard of rainfall and flood discharge using ArcView GIS, HEC-RAS and SWMM on the study area. And real time monitoring system developed is to study various cases on a variety of basins to reduce natural disasters induced by flood in coastal urban area.

An examination of the factor structure of the Psychopathy Checklist : Youth Version and its association with instrumental aggression among violent female youth
Creators: name: Hutton, Erin Lisa
Publisher: name: University of British Columbia
Year: 2011

description: Female youth are a strikingly understudied population within the accumulated forensic literature which is particularly troubling since adolescent females represent a significant and growing population within forensic contexts. The Psychopathy Checklist: Youth Version (PCL:YV; Forth, Kosson, & Hare, 2003) was created to assess psychopathic traits among adolescents, which include interpersonal deceptiveness, affective deficits, and impulsive, antisocial tendencies. However, to ensure its proper use, the underlying factor structure of the PCL:YV must be determined. The primary purpose of this thesis was to examine whether the two-factor, three-factor, or four-facet model is most appropriate for female youth. This is the first study to simultaneously examine all three of the primary factor models among a North American sample of violent female youth offenders. Results demonstrated that the three-factor model is the best-fitting of the three primary PCL:YV factor models among violent female youth offenders. Further, the extant research has repeatedly demonstrated a relationship between the presence of psychopathic traits and instrumental aggression, however, researchers have only recently begun to examine this relationship among juvenile offenders, and females have often been excluded or represent only a small proportion of mixed samples. A secondary goal of the current thesis was to examine the relationship between psychopathy total, factor, and facet scores and instrumental aggression in a sample of female offenders. Contrary to previous studies on male youth, results revealed that female youth with psychopathic traits were not significantly more likely to use instrumental violence in the commission of their violent crimes. Findings and their respective research and clinical applications are discussed.
The House on Bayou Road: Atlantic Creole Networks in the Eighteenth and Nineteenth Centuries

Families

description: This article discusses the coherence and relevance of the concept of "Atlantic creole" by examining the itineraries of two families, one white and one black, whose paths briefly crossed in the Tremé neighborhood of New Orleans in 1811. Through archival and genealogical research conducted in Louisiana, the southwest of France, Spain, and Cuba, the history of each family is reconstructed over the course of two centuries, with multiple crossings and re-crossings between Europe, Africa, and the Americas. Matrimonial strategies and strategies of asset accumulation are examined carefully and compared over several generations, giving us a glimpse of how individual and group identities as well as one's positioning in the social hierarchy were constantly renegotiated. Some characters in each family are directly connected to major historical events: one fought on both sides of the Haitian Revolution; another was the editor of the first black daily in United States history. The study makes the case for the fundamental importance of family networks in Atlantic creole history. It also argues that the origin of Atlantic creole culture in coastal enclaves explains the coexistence of two opposite features: an unusual capacity for self-reinvention and a strong sense of local belonging.

Systematics of fusion probability in "hot" fusion reactions

description: The fusion probability in "hot" fusion reactions leading to the synthesis of super-heavy nuclei is investigated systematically. The quasi-fission barrier influences the formation of the super-heavy nucleus around the "island of stability" in addition to the shell correction. Based on the quasi-fission barrier height obtained with the Skyrme energy-density functional, we propose an analytical expression for the description of the fusion probability, with which the measured evaporation residual cross sections can be reproduced acceptably well. Simultaneously, some special fusion reactions for synthesizing new elements 119 and 120 are studied. The predicted evaporation residual cross sections for 50Ti+249Bk are about 10-150fb at energies around the entrance-channel Coulomb barrier. For the fusion reactions synthesizing element 120 with projectiles 54Cr and 58Fe, the cross sections fall to a few femtobarns which seems beyond the limit of the available facilities.
