The closest point method for time-dependent processes on surfaces

This thesis concerns the numerical solution of time-dependent partial differential equations (PDEs) on general surfaces using a recent technique known as the Closest Point Method. The Closest Point Method represents surfaces with a closest point representation which leads to great flexibility with respect to surface geometry, among other advantages. The computation itself alternates between two steps: first, an explicit time step is performed using standard finite difference techniques on a narrow band of grid points surrounding the surface embedded in a higher dimension; second, a closest point extension is used to maintain consistency with the original surface PDE. The Closest Point Method is applied to the important problem of interface motion on surfaces by using level set equations posed on surfaces. New weighted essentially nonoscillatory (WENO) interpolation schemes are derived to perform the necessary closest point extensions. This approach, in combination with standard Hamilton–Jacobi WENO finite difference schemes and explicit time stepping, gives high-order results (up to fifth-order) on a variety of test problems. Example computations are performed on a sphere, torus, triangulated human hand and Klein bottle to demonstrate the flexibility of the method. A new implicit Closest Point Method is presented for surface PDEs which are stiff, for example, because of diffusion terms. The method uses implicit time-stepping schemes to allow large steps but retains the flexibility with respect to surface geometry of the original explicit Closest Point Method. Numerical convergence studies on the heat equation and a fourth-order biharmonic problem demonstrate the accuracy of the method and a variety of example computations demonstrate its effectiveness. These include an image processing example of blurring on triangulated surfaces, heat diffusion on a surface consisting of multiple components connected by a thin filament and Turing pattern formation on surfaces using implicit–explicit (IMEX) time stepping.
Reducibility of linear equations with quasi-periodic coefficients. A survey

Preface This survey deals with some aspects of the problem of reducibility for linear equations with quasi-periodic coefficients. It is a compilation of results on this problem, some already classical and some other more recent. Our motivation comes from the study of stability of quasi-periodic motions and preservation of invariant tori in Hamiltonian mechanics (where the reducibility of linear equations with quasi-periodic coefficients plays an important role), and this has influenced much of the presentation. The first chapter is an introduction to linear equations with quasi-periodic coefficients and their reducibility. It settles notation that we will use along the survey and gives some motivations for the study of reducibility, as well as a discussion of Floquet theory for periodic systems and some results on the reducibility of linear scalar equations with quasi-periodic coefficients. The second chapter is a survey of results on exponential dichotomy and a related spectrum for linear skew-product flows. This theory applies to general quasi-periodic equations in any dimension, and some results and definitions given there will be used in the following chapters. A reducibility result is included. The third chapter is the longest of the whole survey and it deals with Schrödinger equation with quasi-periodic potential. It is divided into two parts. In the first one we study the classical spectral theory of self-adjoint operators both in the general case and in the case of a quasi-periodic potential. The ergodic invariants like the rotation number and the Lyapunov exponents are discussed in relation with the spectral properties of the Schrödinger operator. The second part is devoted to results on reducibility for this equation and some ideas about the proof, based on KAM techniques, are presented. Finally, some attention is paid to results on non-reducibility for this equation. The fourth chapter tries to give an overview of the existing results on the reducibility of linear equation with quasi-periodic coefficients in dimension greater than two. In the first part of the chapter we study results on reducibility of general quasi-periodic equations, and in the second one we focus on the case when the flow is defined on a compact group, more specifically SO(3, R), because almost all of these systems can be shown to be reducible close to constant coefficients. Finally we give some remarks on non-reducibility for these equations. The survey is not intended to be exhaustive and it is certainly not original, neither in the results …
J-Band Spectroscopy of the z = 5.74 Broad Absorption Line Quasar SDSSp J104433.04–012502.2

We use NIRSPEC, a near-IR spectrometer on Keck II, to obtain moderate-resolution (R = 1540) spectroscopy that shows conclusively that the C IV emission line in the z = 5.74 quasar SDSSp J104433.04-012502.2 is accompanied by broad, blueshifted C IV absorption. The line has a "balnicity index" of 900 km s-1 and a rest-frame equivalent width of 13.1 ± 1.3 Å relative to the continuum. This confirms its membership in the class of objects called "broad absorption line" (BAL) quasi-stellar objects (QSOs). SDSSp J1044-0125 was previously suggested to be a BAL QSO based on its UV-to-X-ray flux ratio, which is larger than most non-BAL QSOs. The C IV emission is of normal strength, implying a metallicity similar to that found in other, lower redshift, QSOs.
“BA-TPF”: A Novel Approach Towards Regression Test Case Optimization

One of the most critical and expensive segment of software development is software testing. It is practically not feasible to conduct exhaustive testing on any software system due to cost and time constraints. Moreover, amendments and modifications in a software for the purpose of fixing failures is inevitable. Therefore, one can never guarantee that a software has been thoroughly tested. Testing the whole software system exhaustively by running the entire set of test cases after every modification is near to impossible. Hence, the software system is tested by running the optimized test suite for minimizing the cost and effort without compromising the quality of the test suite in terms of uncovering faults and providing better coverage based on many parameters. This paper presents a novel technique “BA-TPF” for multi-objective test suite optimization for enhancing path coverage with minimized repetition ratio and minimized test suite size.
Large Eddy Simulation of the Flow Past a Soccer Ball

,e football game is the most popular, played, and loved sport around the world. ,e advent of technological breakthroughs and the continuous increase in consumer demand have led to a revolution in football’s design and manufacturing process. In the past, studies in soccer ball aerodynamics mainly were limited to the investigation of lift and drag forces inside a wind tunnel apparatus. A few researchers have analyzed the flow around the different soccer balls using computational fluid dynamics simulations with the Reynolds-Averaged-Navier–Stokes equations model. ,is study primarily intends to simulate a modern soccer ball (Adidas Telstar 18) using the Large Eddy Simulations technique. ,e whole research is divided into two phases. In the first phase, the flow around a smooth sphere is simulated numerically to validate the meshing strategy, boundary conditions, and solution methodology. ,e same modeling approach is used in the later stage to simulate the flow around a soccer ball. ,e effect of panels and seam on the boundary layer flow separation and overall turbulent flow structure around the soccer ball are visualized. ,e results indicate that the large-eddy simulations help predict the flow intricacies by resolving small eddies near the panels.
On the arithmetic transfer conjecture for exotic smooth formal moduli spaces

In the relative trace formula approach to the arithmetic Gan-Gross-Prasad conjecture, we formulate a local conjecture (arithmetic transfer) in the case of an exotic smooth formal moduli space of p-divisible groups, associated to a unitary group relative to a ramified quadratic extension of a p-adic field. We prove our conjecture in the case of a unitary group in three variables.
Estimates of genetic variability, heritability and genetic advance for grain yield and other yield attributing traits in rice (Oryza sativa L.)

Fifty two rice genotypes were evaluated in randomized block design for twelve metric traits to estimate the extent of genetic variability, heritability (broad sense) and genetic advance as per cent of mean. The analysis of variance revealed significant variability for all the characters studied. Among the 12 characters studied, high phenotypic and genotypic coefficients of variation were recorded for the traits viz. , panicle number per plant, weight of 1000 fully developed grains and grain yield plant -1 indicating that large amount of variation is present among the genotypes. High heritability coupled with high genetic advance as per cent of mean was recorded for time of heading (50% of plants with panicles), stem length (excluding panicle), panicle number per plant, weight of 1000 fully developed grains, decorticated grain width and grain yield plant -1 indicating that these traits were governed by additive gene effects and may be chosen as selection criteria for formulating breeding strategies in rice.
Interval Orders and Shift G raphs

A finite partially ordered set (poset) P = (A, P) is called an interval or­ der if there is a 1 — 1 function which assigns to each element a; 6 A a closed interval [ax , bx ] of the real line R so that x < y in P if and only if bx < ay in R. For a poset (A, P), height (A, P) is the maximum number of points in a chain, while dim(A, P) is the dimension of (A, P), the minimum number of linear orders on A whose intersection is the partial order P. In 1972, I. Ra~ binovitch proved that the function f(n) = max{dim(A, P) : height (A, P) < n, P is an interval order} is defined and satisfies f{n) < [n + 1]. In this paper, we show that f(n) = lg lgn + (1/2 + o(l))(lg lg lgn). The proof techniques in­ clude establishing links between the dimension of interval orders, the chromatic number of shift graphs, and the classical problem of counting the number of antichains in the subset lattice.
Quality of Life in Patients on Renal Dialysis in Urban Area , Dakahlia Governorate ,Egypt

Background : Chronic kidney disease (CKD) is a major health problem worldwide with increase morbidity and mortality and significant impact on patient quality of life (QoL) that is a main component of health outcome. In most of developing countries, the health related QoL gains less attention of health care providers. This needs more assessment to frame the rehabilitation and treatment programs and policies of chronic renal failure patients. General objective : to promote QoL of hemodialysis (HD) patients. Specific objectives to descube QoL among these patients. Methodology: The study is a cross section study conducted on patients with ESRD on regular HD at Talkha central hospital, Dakahlia Governorate, Health related QoL (HRQoL) was assessed using the validated Kidney Disease QoL-Short Form (KDQOL-SF) tool. It includes one multi-item scale. Results: The patients’ QOL scores were very low (below 50) for all subscales. The highest score was on social function (38.86±21 Range 25.0 - 87.5), physical function (33.87±13.76 Range 4.55 - 68.18) and Overall Health Rating (35.61±10.03 Range14.31-61.15) were directing very weakly to the best and the lowest was on role of physical function (8.59 ± 21.46 Range 0 - 100), and Pain (17.18 ± 8.07Range 25.0 - 66.67) . Conclusion: Patients with ESRD on HD generally have a diminution reduction of their quality of life scores. The results of the study showed that there are no differences on QoL among male and female patients while age, occupation and presence of diabetes affect the total QoL score.
ATYPICAL CASE OF PICA RESPONDED TO SSRI

attempts ingestion of mouth He knew that possible medical problems, e.g., of mouth, pain abdomen could develop after long-term ingestion of the substance. But the ingestion was not associated with a feeling of wanting to punish himself, nor did this impulse respond to any other edible substance. In addition, he was not sure whether the feelings of ingestion were compulsive/ impulsive since onset. But for the past year they had definitely had a compulsive/impulsive character. The information was cross-checked with the details provided by his wife. His wife reported that her husband also complained of irritability, headache, anxiety, forgetfulness and occasional sleeplessness. ABSTRACT Pica is a common disorder in childhood, however, in adults it is associated with mental retardation, psychosis and pregnancy. A few case reports have described it being associated with obsessive compulsive disorder in adults. We describe the case of an adult male patient who developed an impulse to ingest 4 to 5 bottles of mouthwash. These thoughts were ego-dystonic and kept on hammering his mind until he ate it. He was diagnosed as having pica. We prescribed him vilazodone 20mg with clonazepam and asked him to ventilate his feelings during stressful situations. He showed remarkable improvement in pica symptoms in 4 weeks. It can be concluded that stress may induce the pica in some adults and that such feelings have impulsive/compulsive characters.
Selected EU Countries Crop Trade Competitiveness from the Perspective of the Czech Republic

: The question of the sources of agricultural competitiveness is widely discussed on the farm and sectoral levels in the European Union. This paper assesses the competitiveness of the plant production using the combination of trade measures and strategic management measures in the selected European countries related to the Czech Republic. Thus, the paper evaluates and identiﬁes the sources of competitiveness of plant production. In the case of Belgium and the Netherlands, labour and capital factors have a signiﬁcant inﬂuence on production; in the case of the new member states, these factors are less important, and, conversely, market competitiveness factors are more crucial. The continuous convergence process between Belgium and the Netherlands is illustrated. The divergence between the Netherlands and the rest of the countries is also visible. There is a stable connection between the Czech Republic and Austria, France, and Slovakia. It can be mentioned that there is no statistically signiﬁcant difference in the comparative advantage between 2005 and 2019, except in the case of France. Analysing sources of competitiveness among the countries of interest is a possible tool for the future direction of trade policies.
PESTE DES PETITS RUMINANTS AMONG SHEEP AND GOATS IN SAUDI ARABIA IN 2004

An outbreak of Peste des petits ruminants (PPR) among and goats was reported in the central and southern regions of the Kingdom of Typical clinical manifestations of acute PPR including, fever, anorexia, diarrhea, mucopurulent nasal and ocular discharges, dyspnea and necro-ulcerative stomatitis were observed with a relatively high case fatality rate among lambs and kids aged 4-9 months. On postmortem examinations, pneumonia, enteritis, hemorrhages and necrosis in the abomasal mucosa, and pleurisy were the most common gross lesions. Both PPRV-antigen and antibody assays were used to confirm diagnosis of the disease. Indirect fluorescent antibody (IFA) technique and immuno-capture ELISA (IC-ELISA) were used for demonstration of PPR viral antigen in the mouth scraping, spleen and lung tissue specimens. The laboratory study indicated that both IFA and IC-ELISA were reliable, rapid and sensitive methods for detection and identification of PPRV antigen. Competitive ELISA (C-ELISA) was used for detection of PPRV-antibodies in ovine and caprine sera. Serodiagnosis revealed that 40.7-100% of the collected sheep and goats sera were positive. In conclusions, the reported PPR outbreak is mostly attributed to the presence of enzootic virulent strains of PPR virus, which could have circulate between the infected and susceptible animals in sheep and goats flocks with no actual national vaccination regime against the disease. The present study recommended that, legalization of the restriction of the animal movement should be applied for sheep and goats populations during the risk period of PPR in different localities of the country. An obligatory vaccination program against PPR virus infection should be applied for all sheep and goats flocks allover the country. Lambs and kids should be vaccinated at 3 rd month of age, when the maternal antibodies decline. – Outbreak Peste des petits ruminants (PPR) – PPR virus – Serodiagnosis
University of Birmingham AftD functions as an 15 arabinofuranosyltransferase involved in the biosynthesis of the mycobacterial cell wall core

Arabinogalactan (AG) is an essential structural macromolecule present in the cell wall of Mycobacterium tuberculosis , serving to connect peptidoglycan with the outer mycolic acid layer. The D-arabinan segment is a highly branched component of AG and is assembled in a step-wise fashion by a variety of arabinofu- ranosyltransferases (AraT). We have previously used Corynebacterium glutamicum as a model organism to study these complex processes which are otherwise essential in mycobacteria. In order to further our understanding of the molecular basis of AG assembly, we investigated the role of a fourth AraT, now termed AftD by generating single ( D aftD ) and double deletion ( D aftB D aftD ) mutants of C. glutamicum . We demonstrate that AftD functions as an a (1 ? 5) AraT and reveal the point at which it exerts its activity in the AG biosynthetic pathway. (cid:1) 2017 The Authors. Published Elsevier B.V.

Coherent structures in weakly birefringent nonlinear optical fibers

This article studies two coupled nonlinear Schrodinger equations that govern the pulse propagation in weakly birefringent nonlinear optical fibers. The coherent structures for these equations, such as vector solitons and localized oscillating solutions, are studied analytically and numerically. Three types of localized oscillating structures are identified and their functional forms determined by perturbation methods. In some of these structures, infinite oscillating tails are present. The implications of these tails are also discussed.
Surgical management of cervical degenerative disc disease - A retrospective analysis of 100 consecutive cases

Background: Surgical management of cervical disc disease may produce faster symptom resolution compared to conservative treatment. Hence the present study was undertaken to analyze the outcome of patients with degenerative cervical disc disease, who were surgically treated via the anterior or posterior approach for cervical disc prolapse. Method: Total 100 consecutive cases of cervical spondylosis and who underwent anterior cervical discectomy and fusion by auto graft and posterior cervical decompression surgery were included in the study. Clinical outcome was analyzed by Nurick’s Grading System. Results: Most of the patients (96%) were surgically intervened via the anterior approach whereas very few patients (4%) were approached through posterior route. The commonest level to be operated through anterior approach was C 5 -C 6 (66.67%) followed by C 4 -C 5 (40.63%) and C 6 -C 7 (35.40%). Anterior cervical discectomy with fusion was done in 53 (53%) cases among them 47 (88.6%) cases had good fusion and 6 (11.3%) had poor fusion. The commonest site of fusion was C 5 -C 6 (64%) followed by C 4 -C 5 (39%) and C 6 -C 7 (34%). Two patients underwent laminectomy and two laminoplasty by posterior approach from C 3 -C 7 levels. Preoperatively, most of the patients (43%) were in Nurick’s grade 0 whereas 7% were in grade V. Postoperatively patients who were in Nurick’s grade 0 improved with no evidence of radiculopathy whereas 2% of patients who were in Nurick’s grade V did not show any improvement. Conclusion: The present study revealed good results with anterior cervical discectomy and fusion even for multiple levels (≥3). Also, significant proportion of patients with poor Nurick’s grade improved well in this study.

Insider timing on the Stockholm Stock Exchange

This paper investigates how CEOs in public Swedish mid-cap corporations time their transactions in their own company’s stock in a short-term perspective. To investigate this, an event study methodology is employed on cumulative returns surrounding these insiders’ transactions, both absolute and relative to the market. We find that these insiders, on average, purchase stock subsequent to a period of decline in both total and abnormal cumulative returns and sell stock following a period of positive total and abnormal returns. This is in line with our hypotheses. We also find that total and abnormal cumulative returns tend to turn and increase for a short period following a purchase transaction, while for a sale transaction, the trend does not turn but continues upward, implying that purchases may be timed more rigorously in the short run than sales. This paper discusses these observations in connection to earlier findings and motivates further research on the subject of insider transaction timing.
Path analysis of factors affecting decision making behavior and work behavior of employees in a large subdistrict administrative organization in Udon Thani Province, Thailand

The objectives of this research were (1) to study the level of Subdistrict Administrative Organizations (SAO)’ employees opinion on work environment, emotional reaction, work attitude, work behavior, and decision making behavior and (2) to study causal effect of factors affecting on work behavior and decision making behavior of Udon Thani SAOs’ employees. The samples consisted of 500 government officers, permanent workers, temporary workers, and general workers of 20 large SAOs in UdonThani Province. The samples were selected by stratified sampling based on each SOA employee proportions. The data collection tool was questionnaires. The data analysis used were descriptive statistics and path analysis. The result of path analysis indicated that the factor with a direct impact on decision-making behavior was work environment, with total effect of 0.096.
