Theory of quantum dot cavity-QED: LO-phonon induced strong coupling and non-equilibrium phonon distributions

Presently, there is considerable activity in cavity quantu m electrodynamics (CQED), which is the study of the interaction between the radiation-field mode and matter, su ch as occurring in a semiconductor quantum dot (QD) embedded in an optical microcavity. Investigations in volving QD-CQED are fueled by interesting physics and potential for tailoring emission properties, e.g. phot on statistics, within an ultrasmall volume [1]. In our contribution, we discuss calculations related to QD-CQED e xperimental and theoretical studies showing intense cavity emission and even lasing in an off-resonant cavity mo de. Here, we further explore the latter situation by including the possibility of longitudinal-optical (LO) ph onons as an enabling source for an off-resonant strong light-matter interaction. Our model is based on an approach, where a set of coupled diffe rential equations describing the photonand
REASONS OF ABSENCE FROM CLINICAL FOUNDATION CLASSES FROM THE VIEWPOINTSOF MEDICAL STUDENTS OF SEMNAN UNIVERSITY OF MEDICAL SCIENCES

Introduction : Absence of students from classes can reduce the quality of education and increase the failure rate. The present study aims to assess the reasons of absence from classes in basic sciences from the viewpoints of medical students of Semnan University of Medical Sciences in 2011. Methods: This cross-sectional study was performed using a questionnaire with the participation of medical students who undertook basic sciences' course and BSc. students who studied in year two of the course. A questionnaire containing demographic data and factors influencing on students' absence including teacher, student, educational processing and physical conditions of classrooms was designed. Students completed the questionnaire before starting of lectures in classrooms. Results: The results showed that 39% of students were absent two hours and 22.4% were absent for four hours per course credit and 38.6% said they were not aim to be absent except in emergency situation. at all. Inappropriate teaching was identified as the main reason for absence (3.53 / 4±1.1) followed by inadequate sleep the night before the class (3.45 / 4±1.33) lack of scholarship in teaching (3.43 / 4±1.21) and lack of self-interest to the field (1.76 / 4±1.13). Conclusion: Education planners should consider factors influencing on absence of students. In faculty recruitment, academic proficiency and scholarship of teaching should also be considered. Moreover, emotional status of students should be noticed.
Allometric models for aboveground biomass of ten tree species in northeast China

China contains 119 million hectares of natural forest, much of which is secondary forest. An accurate estimation of the biomass of these forests is imperative because many studies conducted in northeast China have only used primary forest and this may have resulted in biased estimates. This study analyzed secondary forest in the area using information from a forest inventory to develop allometric models of the aboveground biomass (AGB). The parameter values of the diameter at breast height (DBH), tree height (H), and crown length (CL) were derived from a forest inventory of 2,733 trees in a 3.5 ha plot. The wood-specific gravity (WSG) was determined for 109 trees belonging to ten species. A partial sampling method was also used to determine the biomass of branches (including stem, bark and foliage) in 120 trees, which substantially ease the field works. The mean AGB was 110,729 kg ha -1 . We developed four allometric models from the investiga- tion and evaluated the utility of other 19 published ones for AGB in the ten tree species. Incorporation of full range of variables with WSG-DBH-H-CL, significantly improved the precision of the models. Some of models were chosen that best fitted each tree species with high precision (R 2 ≥ 0.939, SEE 0.167). At the latitude level, the estimated AGB of secondary forest was lower than that in mature primary forests, but higher than that in pri- mary broadleaf forest and the average level in other types of forest likewise.

Direct Cost of Cardiovascular Diseases in Cardiology Department of University Hospital Gabriel Touré (Uh Gt): Comparative Study Between Patients With and Without Medical Insurance

Aim: This study aims to compare cardiovascular diseases direct costs for patients with and those without medical insurance. Methods: It was a prospective study from Mai 02 to August 31 2016 in the cardiology department of the UH GT. All outpatients aged 15 years and older, who came to visit, accepted to participate in the study and were involved. Direct costs (transport, consultation, labor tests and medicaments) were recorded for each patient at each visit. Data were inserted in a MS Access 2010 database and exported in SPSS 20 for analysis, comparing 2 groups (patients with and without medical insurance). Chi-2 and Fisher tests if applicable were used for statistical tests. Results: All patients seen in the study time (922 patients of whom 62.9% were female and 35.7% between 60-74 years ) were included. A proportion of 30.5% had medical insurance (281/922). Patients with diabetes, dyslipidemia and obesity were found among patients with medical insurance with respectively 47.5, 62.4 and 49.2%. Most frequent cardiovascular diseases among patients with medical insurance were high blood pressure without and with complications, acute coronary syndrome with respectively 36.2, 34.7 and 29.2%. Direct costs for patients with medical insurance were 1.06 to 1.77 times higher. Labor tests generated the highest costs. Direct costs for all cardiovascular diseases were higher for patients without medical insurance, up to 4 times for venous thrombo-embolic disease. Total costs were higher for patients with medical insurance. Conclusions: Direct costs for pathologies were higher for patients without medical insurance. Palpitation was the only pathology with direct costs higher for patients with medical insurance. Total costs for patients were higher for patients with medical insurance.
Severe Recurrent Epistaxis - The Main Symptom of Hereditary Haemorrhagic Teleangiectasia

Abstract Hereditary haemorrhagic telangiectasia (HHT), also known as Rendu-Osler-Weber syndrome, is of dominant autosomal inheritance. Pathologic changes of vascular walls cause recurrent episodes of bleeding from many organ systems. Recurrent epistaxis is the first and the most frequent symptom of HHT. The causal therapy is not known but there are many therapeutic procedures improving the overall condition. We present a case of a 76-year-old man suffering from HHT, frequently hospitalized and treated for massive nose bleeding. In past a selective arterial embolization was performed thrice; nonetheless, the intensity and frequency of epistaxis remained unchanged. Anterior nasal package and electrocoagulation were performed repeatedly as the “first aid” treatment. In the article we also mention other therapeutic modalities for this diagnosis; unfortunately, their efficacy remains inadequate.
Modelling the hydrologic behavior of the upper Tiber river basin under climate change scenarios

Precipitation and temperature data are the most frequently used forcing terms in hydrological models. However, the available General Circulation Models (GCMs), which are widely used nowadays to simulate future climate scenarios, do not provide those variables to the need of the models. The purpose of this study is therefore, to apply a statistical downscaling method and assess its strength in reproducing current climate. Two statistical downscaling techniques, namely regression based downscaling and the stochastic weather generator, were used to downscale the HadCM3 GCM predictions of the A2 and B2 scenarios for the Upper Tiber River basin located in central Italy. Four scenario periods, including the current climate (19611990), the 2020s, the 2050s and the 2080s, were considered. The Statistical Downscaling Model (SDSM)based downscaling shows an increasing trend in both minimum and maximum temperature as well as precipitation in the study area until the end of the 2080s. Long Ashton Research Station Weather Generator (LARSWG) shows an agreement with SDSM for temperature, however, the precipitation shows a decreasing trend with a pronounced decrease of summer season that goes up to60% in the time window of the 2080s as compared to the current (19611990) climate. Even though the two downscaling models do not provide the same result, both methods reveal that there will be an impact of climate on the selected basin as observed through the time series analysis of precipitation and temperature. The overall result also shows that the performance of the LARSWG resembled the results of previousstudiesandtheIPCCsAR4projections.
Possibility of N or P limitation for planktonic cladocerans: An experimental test

Threshold food N : C or P : C ratios, below which net production is N or P limited, were calculated for two cladocerans, Daphnia galeata and Bosmina longirostris, based on the N and P contents of body tissue and the C balance between ingestion and net production rates under experimental conditions with various food concentrations from 0.05 to 2.50 mg C liter-‘. With changing food concentration, the threshold N: C and P: C ratios for D. galeata changed in weight ratio from 0.039 to 0.077 and 0.0067 to 0.0120, respectively, with the lowest value at the high food concentration. Changes in threshold ratios for B. longirostris, however, were small and mean values were 0.085 and 0.0080 for the N: C and P: C ratios. As a result, the threshold N: C ratio for D. galeata was lower than for B. longirostris at high food concentrations, while the P : C ratio for B. longirostris was lower than for D. galeata at lower food concentrations. Although the threshold elemental ratios calculated here are theoretically minimum estimates, they were higher than the lower end of the sestonic elemental ratios in some lakes, suggesting that it is not unusual for these cladocerans to be N or P limited at certain periods of the year. Sestonic elemental ratios may have potential importance in determining the community structure of zooplankton.
Changes in the Yield and in the Fatty Acid Composition of Whole Carcass and Selected Meat Portions of Broiler Chickens Fed Full-Fat Oil Seeds

Abstract Broiler chicks were fed eight experimental diets containing two levels (10 and 20%) of either full-fat flax seed (FFS) or full-fat canola seed (FCS), and two levels (3.5 and 7.0%) of canola oil (CO) in combination with either flax meal (FM) or canola meal (CM) at 6.5 or 13%. A corn and soybean meal diet was included as a control. Carcass cut-up yields, total lipids, cholesterol, and fatty acid composition of whole chicken carcasses and white and dark chicken meats were evaluated at the end of a 6-wk feeding period. The 20% FFS diet produced significantly lower live weight and smaller carcass, breast, leg, and neck weights. Feeding 20% FFS, 20% CO + CM, and 10% FCS depressed breast yield. Except for 20% FCS, the rest of the full-fat oil seed treatments increased leg yield significantly. Source (flax, canola) and levels of full-fat oil seeds and CO significantly modulated tissue fatty acid composition. The FFS, 20% FCS, and 20% CO + FM diets resulted in a substantial tissue and carcass enrichment of n-3 fatty acids, linolenic acid, eicosapentaenoic acid, docosapentaenoic acid, and docosahexaenoic acid. Tissue cholesterol and lipid contents were lower in white than in dark meat for all the experimental diets. Generally, birds fed flax products contained less fat in white and dark meat than the birds fed canola. Addition of either FFS or 13% FM to the diet resulted in significantly reduced carcass fat. These trends suggest that dietary FFS could affect total carcass fat and elevate tissue and carcass levels of nutritionally desirable n-3 fatty acids.
A Comprehensive Survey on Cyberbullying Perceptions at a Major Metropolitan University - Faculty Perspectives

Cyberbullying is a concern for any college or university. Digital harassment incidents are featured daily in the news. The authors of this study examine the perceptions of faculty on cyberbullying at a major metropolitan university. From the findings of a survey distributed to faculty in all schools of the university, the authors learn of high levels of perceptions on incidents as an issue, but low levels of perceptions on infrastructural and instructional methods of preemption and resolution, at the university. This study will be beneficial to faculty in colleges and universities, as cyberbullying is considered an issue more frequent in high schools.
Matrix computations for query expansion in information retrieval

Information retrieval (IR) is the task of identifying information items (documents) that are relevant to a user query from a collection. The most popular IR research technique, the vector space model (VSM), is a word-matching approach: it uses the words in common between the query and the document as a basic way of determining their similarity. Because the same concept can be expressed in the query and document using very different vocabularies, synonymy can cause a document to be judged as irrelevant by VSM. Query-expansion methods deal with this problem by automatically supplying the query with additional words that are related to those already in it. Latent semantic indexing (LSI) is a statistical method that derives term associations through a reduced dimensional singular value decomposition (SVD) of a matrix formed from the collection. LSI has equaled or outperformed VSM on many relatively small retrieval collections. But, with the growing size of modern information repositories, LSI has failed to demonstrate its advantage over traditional word-matching methods on some of these large corpora. In this work, I provide evidence that LSI is not reaching its potential for large collections because existing SVD implementations are not able to compute a sufficiently large number of dimensions. I establish a unified framework of vector-based information retrieval called dimension equalization . Through this, I present approximate dimension equalization (ADE), a method that “extrapolates” the result of a high-dimensional SVD based on a relatively small number of computed dimensions. Experiments indicate that ADE improves retrieval performance over LSI and has great utility in cross-language applications. I also investigate sampling approaches to reducing LSI computation, which use only a subset of the document collection to build LSI term-associations. My focus is on local LSI, a variation of the ever-popular local feedback approaches in the IR community. This method computes an SVD on a subset of documents that are related to the query. Experiments show that local LSI outperforms not only the global sampling methods but also the baseline VSM or LSI without sampling. I extend the existing local LSI approach to cross-language retrieval and present its high-quality results.

FACTORS AFFECTING JOB SATISFACTION AMONG PERSONNEL OF THE JIHAD-E- KESHAVARZI ORGANIZATION OF ILAM PROVINCE, IRAN

The main purpose of this study was to investigating factors affecting job satisfaction among personnel of Jihad-e-Keshavarzi Organization of Ilam Province. The nature of this research was applied that done by causal-correlation method. The population for this study comprised all personnel of Jihad-e-Keshavarzi organization in Ilam Province (N=123). Data for this study were collected through structured and pre-tested questionnaire. The questionnaires of the research were sent to the all statistical population of the study, which finally 111 questionnaires were completed and returned. The validity of the questionnaire was determined by the opinions of expert group and its reliability was calculated by using Cronbach's alpha coefficient (? = 0.89). The data were analyzed using statistical methods such as frequencies, percentage and mean comparison, correlation and regression analysis. The results of the study showed that the majority of the personnel (87.4 percent) belonged to medium level of job satisfaction. Findings of the mean comparison showed that there was significant difference between job satisfaction of personnel of Jihad-e-Keshavarzi Organization based on variables like gender, marital and employment status. Results of correlation analysis showed that the number of children had significant and negative correlation with job satisfaction, and variables of age, work experience, salary and education level correlated significant and positive with job satisfaction of respondents. Also, based on the results of multiple stepwise regression analysis 61.5 percent of the variance of the job satisfaction is explained by three variables of "salary", "education level" and "work experience".
Positive provability logic for uniform reflection principles

We deal with the fragment of modal logic consisting of implications of formulas built up from the variables and the constant `true' by conjunction and diamonds only. The weaker language allows one to interpret the diamonds as the uniform reflection schemata in arithmetic, possibly of unrestricted logical complexity. We formulate an arithmetically complete calculus with modalities labeled by natural numbers and \omega, where \omega corresponds to the full uniform reflection schema, whereas n<\omega corresponds to its restriction to arithmetical \Pi_{n+1}-formulas. This calculus is shown to be complete w.r. t. a suitable class of finite Kripke models and to be decidable in polynomial time.
Juvenile Frogs Compensate for Small Metamorph Size with Terrestrial Growth: Overcoming the Effects of Larval Density and Insecticide Exposure

Abstract I reared four species of anurans (Rana sphenocephala [Southern Leopard Frog], Rana blairi [Plains Leopard Frog], Rana clamitans [Green Frog], and Bufo woodhousii [Woodhouse's Toad]) for seven to 12 months in small, outdoor terrestrial enclosures (1 × 2 m) to examine the consequences of larval competition (via density) and contaminant exposure (via the insecticide carbaryl). I added six Rana clamitans, eight Rana sphenocephala, eight Rana blairi, and 10 Bufo woodhousii to terrestrial enclosures shortly after metamorphosis and recaptured them during the following spring. All anurans from low-density ponds were significantly larger than those from high-density ponds, but these size differences did not significantly affect survival to or size at spring emergence. However, R. sphenocephala, R. blairi, and R. clamitans that survived to spring had been larger at metamorphosis on average than those that did not survive; in contrast, B. woodhousii that survived the winter were smaller at metamorphosis on average than those that did not survive. Carbaryl exposure affected mass at metamorphosis of R. clamitans and B. woodhousii that were added to enclosures, but this difference disappeared or did not increase by spring emergence. Overall, exposure to carbaryl during the larval period did not have any apparent effects on survival or growth during the terrestrial phase. In my study, anurans were able to offset small size at metamorphosis with terrestrial growth, although there was a trend of reduced overwinter survival for ranid species that metamorphosed at a smaller size.
The Effectiveness of Early Intensive Intervention in Modifying the Frequency of Repetitive Behavior for Children with ASD in Egypt

The present study aims to test the effectiveness of an integrated training program for early intervention based on Applied Behavioral Analysis (ABA) to improve some of the repetitive behavior patterns (stereotyped behavior, self-harm behavior, compulsive behavior, ritual behavior, sameness behavior, unrestricted behavior) among a sample of children with autism. It uses an experimental approach, with experimental and control groups (N = 17 for each group) and three-time interval assessments (pre, post and follow-up). The study uses several assessments such as the Goddard Measure of Intelligence, a Socio-economic Status Form (Abo Hamza & Helal, 2013), and the Stereotyped Behavior Scale (RBS-R) [1]. Statistical analysis has been performed using the Pearson correlation, and Chi-square, Mann- Whitney, Eta-squared and Z tests for each time assessment from the two groups to identify interaction effects. Results indicate that the intervention program has a positive effect on modifying the stereotyped behavior patterns in both post- and first follow-up assessment (after two weeks). However, the study shows no positive effect for the second follow-up assessment (after two months).
Cmos Imagers: From Phototransduction To Image Processing

This is the first book published on CMOS imagers. It covers the full chain, starting from the basic concepts of photo transduction, and continues with pixel and system examples of CMOS Active Pixel Sensor (APS) imagers. CMOS Imagers: From Phototransduction to Image Processing contains six contributed chapters. The first three detail the basic concepts of photo transduction, modeling, evaluation, and optimization of APS. The last three continue with the description of APS design issues using a bottom-up strategy, starting from pixels and finishing with image processing systems. Various focal-plane image processing alternatives to either improve imaging or to extract visual information are presented. The book closes with a discussion of a completely non-traditional method for image noise suppression. Targeted audiences for this work are people interested in imaging, whether from the academic, the industrial or the scientific arena. All students, engineers and technical workers interested in understanding more about the physics, the design and the potential of CMOS imagers are invited to read the book. Each chapter can also be read independently.
