Sparse preconditioners for dense linear systems from electromagnetic applications

Dans cette these, nous etudions des preconditionneurs creux par inverse approche pour la resolution de systemes lineaires denses issus d'applications en electromagnetisme en formulation integrale. L'objectif de ce travail etait le developpement de preconditionneurs robustes et paralleles pouvant etre integres ulterieurement dans des codes de simulation capables de traiter des geometries industrielles de tres grandes echelles. Dans un premier temps, nous avons realise une etude comparative des divers preconditionneurs initialement developpes en algebre lineaire creuse en les adaptant au traitement des matrices denses. En particulier, nous avons propose une strategie efficace permettant de definir a priori la structure creuse d'un preconditionneur base sur un inverse approche minimisant la norme de Frobenius. Cette approche a ete implantee par un autre doctorant dans un code parallele qui exploite une methode "fast multipole" pour le calcul de l'operation produit matrice-vecteur dans les methodes de Krylov. Ce code nous a permis d'evaluer l'evolutivite de notre preconditionneur lors de la resolution de systemes lineaires de taille croissante et d'en caracteriser les limitations. Afin de repousser ces limitations, nous avons propose un schema numerique base sur des iterations emboitees qui nous a permis d'ameliorer notablement la robustesse de notre preconditionneur sur des problemes de grande taille. Cette technique nous a permis de reduire les couts de calcul ainsi que de pouvoir traiter des geometries complexes telle que celle d'un avion avec plus d'un million de degres de liberte. Enfin, nous avons egalement realise une etude preliminaire sur des preconditionneurs 2 niveaux spectraux qui exploitent des proprietes spectrales du systeme preconditionne.

Association of Diligence and Sociability with Stroke: A UK Biobank Study on Personality Proxies.

BACKGROUND There is a growing interest in how personality may be related to the risk of developing disease. Associations between personality and stroke have so far only been studied in relation to stroke mortality. However, many stroke survivors suffer severe impairment of quality of life due to sequelae such as aphasia, hemiparesis, depression and anxiety. In this study we assess the association between personality and risk of stroke, regardless of mortality. METHODS Using self-reported data on psychological factors, mental health and social support, proxies for the Big Five personality traits were developed for 482,535 participants in the UK Biobank. Logistic regression and Cox proportional hazard models, with 95% confidence intervals (CI), were used to estimate odds ratios (OR) and hazard ratios (HR) between each personality trait and stroke prevalence (N = 6793) and incidence (N = 3312), respectively. Models were adjusted for demographic, health-related, and lifestyle factors. RESULTS Diligence and sociability were associated with a lower risk of stroke incidence in the fully adjusted model (respectively: [HR = 0.92; 95% CI = (0.88, 0.96)], [HR = 0.93; 95% CI = (0.89, 0.97)]). However, nervousness, curiosity and warmth were not significantly associated with a risk of stroke incidence. CONCLUSIONS Individuals with higher levels of diligence and sociability may be at a reduced risk of developing stroke. With respect to the debated role of neuroticism in relation to cardiovascular disease, we did not find evidence of an association between nervousness and risk of developing stroke.
Multiobjective Scheduling of Hybrid Synchronization Messages

One of the essential aspects of distributed simulations is to order events according to a causal consistency model. However, traditional approaches are costly in terms of processing to ensure causality. A promising approach to order events is using a hybrid synchronization approach, where processes can alter dynamically between optimistic and conservative approaches. Unfortunately, synchronizing processes running a hybrid synchronization is a complex problem. In this work, we discuss a multi-objective scheduling of hybrid synchronization messages problem. Beyond that, we propose using a scheduling algorithm and describe how to integrate the algorithm in an existing distributed simulator. Finally, we propose a preliminary analysis of our algorithm regarding work done and the number of messages.
Factors Influence the Purchase Intention of Electric Vehicles in Egypt

The sales rate of Electric Vehicles is growing rapidly worldwide. On the contrary, EVs are not achieving the same rate of popularity in emerging markets like Egypt. Some researchers suggest that developed countries have better infrastructure, governmental frameworks, and policies to support mass adoption, other researchers claim that consumers in developed markets have higher environmental awareness that drives them to adopt cleaner transportation means. In Egypt, research investigating EVs’ unpopularity is limited. Therefore, the researchers studied the factors that influence the purchase intention of EVs in Egypt to bridge this gap and accelerate the penetration rate of EVs in the Egyptian market. This study used the TPB model to study the effect of Attitude, subjective norms, and perceived behavioral control on the purchase intention of adopting an EV in Egypt. In addition, the literature review suggested including Environmental knowledge and Governmental Policies & Support to study their effect on the intention of EVs’ adoption besides the regular TPB independent variables. The conceptual framework of this study hypothesized several relationships and for that, data was collected through a self-administered questionnaire from a sample of 113 passenger vehicle prospective buyers in Egypt. Results show that Governmental Policies & Support alone can explain 39.1% of the purchase intention of EVs in Egypt, followed by Attitude and Perceived Behavioral Control with 8.1% and 3.2% respectively. The findings highlight the importance of Governmental Policies & Support on the EVs’ adoption intention in emerging markets generally and in Egypt specifically.
Identifying the Barriers and Facilitators for Adherence Among Type 2 Diabetes Patients: Role of Health Behavior Change Models

The diagnosis of type 2 diabetes results in several complications which can be prevented with adherence to dietary, exercise and medical regimen. But many people fail to follow this. The objective of this study is to detect that factors the prevent and promote adherence with the role of health behavior change models along with counselling approach and an intervention to achieve change in individuals. The results show that adherence is determined by environmental and personality factors and the theories target these variables to elicit change among people. The paper implicates the importance of doctor patient communication and utilization of social support networks to increase adherence in people with diabetes.
Semi-analytical Model of Laser Resonance Absorption in Plasmas

When an electromagnetic wave is obliquely incident on an inhomogeneous high density plasma, it will be absorbed resonantly as long as it is polarized in the plane of incidence and has an electric field component along the plasma electron density gradient. This process takes place by linear mode conversion into an electron plasma wave. In this paper, we have considered the resonant absorption of laser light near the critical density of a plasma with linear electron density profile. The behaviour of the electric and magnetic vectors of a laser light propagating through inhomogeneous plasma has been studied by calculating them using Maxwell's equations using a new semi-analytical model. The absorbed fraction of the laser light energy, then, evaluated and plotted versus the angle of incidence. It has been shown that this new model can explain the previous classical approximated results at high density scale lengths as well as the reported numerical results in almost all density scale lengths.
An Assessment of Number Sense among Secondary School Students.

This paper reports selected findings from a study of number sense proficiency of students aged 13 to 16 years in a state in Malaysia A total of 1756 students, from thirteen schools in a state in Malaysia participated in this study. A majority (74.9%) of these students obtained an A grade for their respective year-end school examinations. The design for this study was quantitative in nature where the data on student‘s sense of numbers was collected using Number Sense Test adapted from McIntosh et. al.,(1997). The results from this study indicate that students obtained a low percentage of success rate ranging from 37.3% to 47.7% across the levels. There was no significant difference in the results between Secondary 1 students and Secondary 2 students and also between Secondary 3 students and Secondary 4 students. In terms of gender comparison, although the male students obtained a higher score than their female counterparts, this difference was only significant among the Secondary one student‘s. It seems that an over reliance on paper and pencil computation at the expense of intuitive understanding of numbers is taking place among these students.
A study on the Impact of Cancer Awareness Program in improving the awareness and vaccine uptake for Cervical cancer in Nursing students of a tertiary care hospital of Bhubaneswar

Despite the evidence of Human Papilloma Virus vaccination, as an effective mode of primary prevention of cervical cancer, the uptake of vaccine is very less. There being a lot of gaps regarding knowledge about HPV vaccination, its safety, efficacy and availability, the study was done to assess the effect of awareness programs in the acceptance of safe practices for prevention of cervical cancer. Using a longitudinal study design, a study was conducted among 152 B.Sc. nursing students of a tertiary care teaching hospital; using a researcher-made questionnaire. An awareness session was organized to educate them on cervical cancer prevention. The same questionnaire was re-administered as a post- test after a period of one month. Data collected was entered into Microsoft excel spreadsheet; analyzed using EpiInfo software. Data was represented using appropriate statistical tests; taking a p-value of < 0.05 as statistically significant. The mean-age of the study participants was 20.92 + 1.68 years. As few as15.1% knew that “HPV infection is generally asymptomatic”, pre-awareness session. There was considerable improvement in the knowledge regarding the symptoms of carcinoma of cervix post the awareness drive, results were was also statistically significant (p< 0.001). Similarly, their knowledge regarding various risk factors of carcinoma cervix, PAP smear test as a screening tool, also had a marked improvement, post the awareness session. 52.6% were hesitant to take the HPV vaccine pre-awareness session, whereas 73.6% agreed for the same after the awareness program. Although prior to the awareness drive their knowledge about cervical cancer was poor, but there was a significant improvement in their level of knowledge after it. Thus awareness programs can be conducted to inculcate safe lifestyle practices. For wider dissemination, more numbers of awareness drives and at frequent intervals should be done.
The E2F-Regulated Gene Chk1 Is Highly Expressed in Triple-Negative Estrogen Receptor (cid:1) /Progesterone Receptor (cid:1) /HER-2 (cid:1) Breast Carcinomas

We previously showed that checkpoint kinase 1 ( Chk1 ) and Claspin , two DNA-damage checkpoint proteins, were downregulated by 1,25-dihydroxyvitamin D 3 , a known inhibitor of cell proliferation. In the present study, we aimed to investigate the transcriptional regulation of Chk1 and Claspin and to study their expression levels in human breast cancer tissue. Transient transfection experiments in MCF-7 breast cancer cells showed that promoter activities of Chk1 and Claspin were regulated by the E2F family of transcription factors. Subsequently, transcript levels of Chk1, Claspin , and E2F1 were determined by quantitative reverse transcriptase-PCR analysis in 103 primary invasive breast carcinomas and were compared with several clinicopathologic variables in breast cancer. A strong correlation was found between Chk1 and Claspin transcript levels. Transcript levels of Chk1, Claspin , and E2F1 were highest in histologic grade 3 tumors and in tumors in which the expression of estrogen receptor (ER) and progesterone receptor (PR) was lost. Moreover, Chk1 expression was significantly elevated in grade 3 breast carcinomas showing a triple-negative ER (cid:1) /PR (cid:1) /HER-2 (cid:1) phenotype compared with other grade 3 tumors. Further research is warranted to validate the use of Chk1 inhibitors in triple-negative breast carcinomas for which treatment strategies are limited at present. Res 2007;67(14):6574–81] immunostaining was for and was situ hybridization of gene expression after addition of serum to serum-starved cells was assessed by the Fisher’s least significant difference multiple comparison test. For the transfection experiments, differences between E2F overexpression and empty vector control (pcDNA3.1) were analyzed by Student’s t test. Differences in gene expression levels across patient groups, defined by histologic tumor grade; lymph node metastases; ER, PR, or HER-2 status; and tumor size were assessed by the Mann-Whitney U (two groups) or Kruskal-Wallis (three or more groups) tests. The Pearson product-moment correlation coefficient was used to evaluate the associations between Chk1, Claspin, E2F1 , and Ki-67 . Logistic regression was implemented to determine whether Chk1, Claspin, E2F1 , or Ki-67 expression was a significant predictor of histologic tumor grade; lymph node metastasis; or ER, PR, or HER-2 status. Considering grade 3 breast carcinomas separately, we further examined whether Chk1, Claspin, E2F1 , or Ki-67 gene expression levels could predict ER, PR, and/or HER-2 status.
On Bloch-Kato's Tamagawa number conjecture for Hecke characters of imaginary quadratic number fields

This is essentially the author's thesis submited to The University of Chicago (May 1997). I prove the validity of Tamagawa number conjecture of Bloch-Kato for certain Hecke characters. I study the exponential map and local Tamagawa number for all odd primes (both ordinary and supersingular), using Kato's explicit reciprocity law for one dimensional Lubin-Tate formal group. I also study p-part of Shafarevich-Tate group for motives associated to Hecke characters, using Rubin's Main Conjecture in Iwasawa theory. Interestingly a congruence property between p-adic periods of elliptic curve and weight 1 Eisenstein series evaluated at torsion CM points play a crucial role in the proof of Bloch-Kato conjecture.

Cytocompatibility and bioactive potential of AH Plus Bioceramic Sealer: An in vitro study

Abstract Aim To assess the cytocompatibility and bioactive potential of the new calcium silicate cement‐based sealer AH Plus Bioceramic Sealer (AHPbcs) on human periodontal ligament stem cells (hPDLSCs) compared with the epoxy resin‐based sealer AH Plus (AHP) and the calcium silicate cement‐based sealer Endosequence BC Sealer (ESbcs). Methodology Standardized sample discs and 1:1, 1:2 and 1:4 eluates of the tested materials were prepared. The following assays were performed: surface element distribution via SEM–EDX, cell attachment and morphology via SEM, cell viability via a MTT assay, cell migration/proliferation via a wound‐healing assay, osteo/cemento/odontogenic marker expression via RT‐qPCR and cell mineralized nodule formation via Alizarin Red S staining. HPDLSCs were isolated from extracted third molars. Comparisons were made with hPDLSCs cultured in unconditioned (negative control) or osteogenic (positive control) culture media. Statistical significance was established at p < . 05. Results A higher peak of Ca2+ was detected from ESbcs compared with AHPbcs and AHP in SEM–EDX. Both AHPbcs and ESbcs showed significantly positive results in the cytocompatibility assays (cell viability, migration/proliferation, attachment and morphology) compared with a negative control group, whilst AHP showed significant negative results. Both AHPbcs and ESbcs exhibited an upregulation of at least one osteo/odonto/cementogenic marker compared with the negative and positive control groups. Both ESbcs and AHPbcs showed a significantly higher calcified nodule formation than the negative and positive control groups, indicative of their biomineralization potential and were also significantly higher than AHP group. Conclusion AH Plus Bioceramic Sealer exhibited a significantly higher cytocompatibility and bioactive potential than AH Plus and a similar cytocompatibility to that of Endosequence BC Sealer. Endosequence BC Sealer exhibited a significantly higher mineralization potential than the other tested sealers. The results from this in vitro study act as supporting evidence for the use of AH Plus Bioceramic Sealer in root canal treatment.
Galaxy Orbits for Galaxy Clusters in the Sloan Digital Sky Survey and Two Degree Field Galaxy Redshift Survey

We present the results of a study for galaxy orbits in galaxy clusters using a spectroscopic sample of galaxies in SDSS and 2dFGRS. We have determined the member galaxies of Abell clusters covered by these surveys using the galaxies’ redshift and positional data. We have selected 10 clusters using three criteria: the number of member galaxies is greater than or equal to 40, the spatial coverage is complete, and the X-ray mass profile is available in the literature. We derive the radial profile of the galaxy number density and velocity dispersion using all, early-type, and late-type galaxies for each cluster. We have investigated the galaxy orbits for our sample clusters with constant and variable velocity anisotropies over the clustercentric distance using the Jeans equation. Using all member galaxies, the galaxy orbits are found to be isotropic within the uncertainty for most of the sample clusters, although it is difficult to conclude strongly for some clusters due to the large errors and the variation as a function of the clustercentric distance in the calculated velocity anisotropies. We investigated the orbital difference between early-type and late-type galaxies for four sample clusters and found no significant difference between them.
Isolation, Assessments of Risk Factors, and Antimicrobial Susceptibility Test of Klebsiella from Gut of Bee in and around Haramaya University Bee Farm, East Hararghe, Oromia Regional State, Ethiopia

A cross-sectional study was employed from March 2021 to October 2021 to isolate and identify Klebsiella species found in the gut of honey bees collected from worker of honey bee (Apis mellifera) from hives in Haramaya University bee farm, Damota and Finqile's, managed under traditional and modern beekeeping apiculture. From the selected farm, a total of 60 samples of live adult honey bees were collected purposively. The live adult worker of the honey bee was individually surface-sterilized and complete alimentary canals of the worker bee were dissected and processed for Klebsiella isolation. Descriptive statistics were used to describe the occurrence of Klebsiella species and the proportion of Klebsiella found in the gut was analyzed for the association with study variables by the Pearson chi-square test. The overall prevalence of Klebsiella spp. was 50% from samples. The prevalence of Klebsiella pneumoniae was 26.7% and that of Klebsiella oxytoca was 23.3% from isolated using bacteriological examined samples. The isolates were characterized for the antimicrobial susceptibility test using the disc diffusion method. Among the isolated colonies, Klebsiella pneumoniae had the highest resistance to ampicillin (84.2%) and showed less resistance to gentamycin and trimethoprim sulfamethoxazole (26.3%). Klebsiella oxytoca was highly resistant to ampicillin (54.5%) and erythromycin (54.5%) and showed low and equal resistance to gentamycin and amoxicillin (18.2%). Molecular characterization should be conducted to identify Klebsiella spp. from honey bees. Monitoring antimicrobial effectiveness is recommended to tackle the existing problem in apiculture farms, and its possible public health threat should be noted for community by public health professionals.
