A novel grid interactive hybrid power supply system for telecom application

Telecom providers in India are facing a tough challenge to ensure a reliable service due to non-availability of continuous grid supply. This is particularly so in rural areas. Currently, diesel generators are used to ensure continuous power supply. This increases greenhouse gas emission, fuel cost and requires regular maintenance. Instead, renewable energy sources can be effectively used to mitigate these issues and to provide a long term sustainable solution. An attempt is made to design a telecom power supply using hybrid wind/solar photovoltaic (PV) energy systems. Utility grid/diesel generator are used only for backup purpose. The proposed system consists of PWM boost rectifier cascaded with a bidirectional dc-dc converter for interaction with the grid. A single dual input converter which is a combination of Cuk and buck converters, is used to process power from renewable sources. This configuration allows two sources to supply the load separately or simultaneously depending on their availability. Principle of operation of the system is discussed. In order to predict the performance of the system, detailed simulation studies are carried out and results are presented.
Functional impairment in the remission phase of bipolar disorder.

OBJECTIVES The purpose of this study was to evaluate functional impairment in a group of patients with bipolar disorder in remission and to determine the extent of relationships between overall functioning and current depressive, manic and panic spectrum symptoms. METHOD A subset of the patient population at the Pittsburgh site of the Systematic Treatment Enhancement Program in Bipolar Disorder (STEP-BD) study was evaluated in this study. The subsample comprises 103 male and female subjects with bipolar I disorder (n = 70), bipolar II disorder (n = 24), schizoaffective disorder - bipolar type (n = 4), or bipolar disorder NOS (n = 5). Subjects were evaluated in a period of remission (at least 4 weeks with no more than two depressive or manic symptoms). Subjects were assessed for overall functional status using the Work and Social Adjustment Scale (WSAS) and for current bipolar and panic spectrum symptoms using the Mood Spectrum Self-Report questionnaire (MOODS-SR) and Panic-Agoraphobic Spectrum Self-Report questionnaire (PAS-SR). RESULTS The median WSAS total score in these remitted subjects was 14, indicating significant functional impairment. Regressing WSAS on current depressive, manic, and panic spectrum total scores, we observed a highly significant depressive spectrum effect (t = 4.9, df = 94, p < 0.0001), but non-significant panic and manic spectrum effects (t = 1.3, df = 94, p = 0.19 and t = -1.8, df = 94, p = 0.07, respectively). CONCLUSION Bipolar disorder is associated with functional deficits even during periods of sustained and substantial remission. The degree of functional impairment is correlated with the degree of depressive spectrum symptoms.
Towards a complete documentary heritage of Zimbabwe. Whither oral history?

The history of Zimbabwe, like the rest of post-colonial Africa is replete with bias, prejudice, inaccuracies and misconceptions, since some of it was a product of colonialists who had their own interests to serve. Oral history has come as a great relief. With it, Zimbabwe can now have a balanced and more complete documentary heritage. However, the National Archives of Zimbabwe’s Oral History Unit faces a number of challenges, resulting in the Unit lacking national vibrancy and visibility. This empirical study made use of the descriptive survey method, where data were collected through questionnaires and observation. Content analysis of the Directors’ Reports and other secondary sources was also used. The study highlighted the centrality of oral history as a source of history and hypothesized that more resources need to be mobilized for the Oral History Unit to be more visible and more vibrant, for the nation to have a balanced and more complete record of the past.
2 . 2 Identifying Relevant Citations from “ pure ” MIS Journals

The research community has long and often been fervently keen on debating the topic of journal impact. Well, just what is the impact of a journal? Today, the Science Citation Index (SCI) recognizes over 7,000 journals. The sheer number of available journals renders it pivotal for researchers to accurately gauge a journal’s impact when submitting their papers, as it has become commonplace that researchers regard publishing their work in established journals to have significant influence on peer recognition. For journals in Management Information System (MIS), such research studies have continuously been published since the 1990s. Nine of them have been summarized by Carol Saunders [11], whereby seven were based on respondent perceptions by surveying experts, and two were based on the citation quantity to indicate the journal impact.
Learning with Transformation Invariant Kernels

This paper considers kernels invariant to translation, rotation and dilation. We show that no non-trivial positive definite (p.d.) kernels exist which are radial and dilation invariant, only conditionally positive definite (c.p.d.) ones. Accordingly, we discuss the c.p.d. case and provide some novel analysis, including an elementary derivation of a c.p.d. representer theorem. On the practical side, we give a support vector machine (s.v.m.) algorithm for arbitrary c.p.d. kernels. For the thin-plate kernel this leads to a classifier with only one parameter (the amount of regularisation), which we demonstrate to be as effective as an s.v. m. with the Gaussian kernel, even though the Gaussian involves a second parameter (the length scale).
Compressive sensing strategy for classification of bearing faults

Owing to the importance of rolling element bearings in rotating machines, condition monitoring of rolling element bearings has been studied extensively over the past decades. However, most of the existing techniques require large storage and time for signal processing. This paper presents a new strategy based on compressive sensing for bearing faults classification that uses fewer measurements. Under this strategy, to match the compressed sensing mechanism, the compressed vibration signals are first obtained by resampling the acquired bearing vibration signals in the time domain with a random Gaussian matrix using different compressed sensing sampling rates. Then three approaches have been chosen to process these compressed data for the purpose of bearing fault classification these includes using the data directly as the input of classifier, and extract features from the data using linear feature extraction methods, namely, unsupervised Principal Component Analysis (PCA) and supervised Linear Discriminant Analysis (LDA). Classification performance using Logistic Regression Classifier (LRC) achieved high classification accuracy with significantly reduced bandwidth consumption compared with the existing techniques.
Research Paper: Evaluation of a Command-line Parser-based Order Entry Pathway for the Department of Veterans Affairs Electronic Patient Record

OBJECTIVE To improve and simplify electronic order entry in an existing electronic patient record, the authors developed an alternative system for entering orders, which is based on a command- interface using robust and simple natural-language techniques. DESIGN The authors conducted a randomized evaluation of the new entry pathway, measuring time to complete a standard set of orders, and users' satisfaction measured by questionnaire. A group of 16 physician volunteers from the staff of the Department of Veterans Affairs Puget Sound Health Care System-Seattle Division participated in the evaluation. RESULTS Thirteen of the 16 physicians (81%) were able to enter medical orders more quickly using the natural-language-based entry system than the standard graphical user interface that uses menus and dialogs (mean time spared, 16.06 +/- 4.52 minutes; P=0.029). Compared with the graphical user interface, the command--based pathway was perceived as easier to learn (P<0.01), was considered easier to use and faster (P<0.01), and was rated better overall (P<0.05). CONCLUSION Physicians found the command- interface easier to learn and faster to use than the usual menu-driven system. The major advantage of the system is that it combines an intuitive graphical user interface with the power and speed of a natural-language analyzer.
Islam, Jihad, and Terrorism in Post-9/11 Arabic Discussion Boards

This study analyzed the contents of three of the most popular Arabic-language online message boards regarding the attacks of September 11, 2001 on the United States. Although terrorists claimed that the attacks were committed in the name of Islam, those who posted messages on all three forums rejected this claim. More than 43% of the messages condemned the attacks as a criminal act of terrorism that contradicts the core teachings of Islam. Some 30% saw some justification behind the attacks, even if they felt sorry for the victims and their families. However, those participants viewed the attacks as a political, rather than a religious, issue.
Stressors, Coping and Coping Strategies among Young Adults with Cancer

Introduction: Research shows that young adults with cancer experience physical and mental changes that affect both their body image and their ability to cope with the situation. The purpose of this study was therefore to describe stressors, coping and coping strategies among young adults with cancer. Study design: A qualitative interview study. Material and methods: Setting: Swedish university hospital. Data was collected through semi-structured interviews until saturation (12 informants). The interviews were transcribed verbatim and analysed using a phenomenographic approach. Results: Four categories of stressors where identified: ’feeling physically ill’, ‘side-effects of the cancer treatment that caused negative wellbeing’, ’how can I have cancer when I have none or few symptoms from my body? ’ and ‘feelings of psychological distress’. Identified coping styles were ‘physical exercise’, ‘seeking professional help’, ‘trying to regain control’, ‘finding new ways of thinking / acting’ and ‘seeking help from family and friends’. Coping strategies used were problem-focused, emotion-focused, meaning-based and social coping. The informants also used various forms of psychological defense mechanisms. Conclusion: Young adults with cancer experienced stressors similar to older cancer patients but also specific stressors related to their youth based on a lack of previous experience of severe illness which is an important implication for health care personal. Physical exercise was identified as a coping strategy and further studies are needed to investigate if supervised physical exercise may increase internal locus
Interleukin-4 receptor-targeted cytotoxin therapy of androgen-dependent and -independent prostate carcinoma in xenograft models.

Prostate cancer is the most commonly diagnosed solid tumors in United States men. Survival with advanced prostate cancer is dismal because of a lack of effective treatments. Overexpression of interleukin 4 receptors (IL-4R) on prostate carcinoma cells makes them suitable targets for the interleukin 4 (IL-4) fused Pseudomonas exotoxin, IL-4 cytotoxin (IL4-CTx). Androgen-dependent (LNCaP) and -independent (DU145) human prostate cancer cell lines overexpress IL-4Rs and are exquisitely sensitive to IL4-CTx. Using LNCaP and DU145 cell lines, IC(50) values of 4.5 +/- 2.0 and 6.5 +/- 0.5 ng/ml, respectively, were obtained for IL4-CTx in protein synthesis inhibition assays. Primary cultures established from prostate tumor biopsies were equally sensitive to the cytotoxic effects of IL4-CTx. Reverse transcription-PCR analysis, although not quantitative, indicated the presence of mRNA for IL-4Ralpha, a primary subunit of the IL-4R receptor complex in prostate carcinoma cell lines, primary cultures, benign prostatic hyperplasia, and prostate carcinoma tissues. Immunohistochemistry studies revealed the presence of IL-4R in benign prostatic hyperplasia and prostate carcinomas. Five daily (QD) injections of IL4-CTx (100 micro g/kg) administered i.v. , i.p., or intratumoral (i.t.) caused several complete responses in nude mice with s.c. DU145 and LNCaP tumors. i.t. injections of IL4-CTx elicited tumor regression in a dose-dependent manner with complete responses occurring in 100% of the animals when treated with IL4-CTx (500 micro g/kg) given five QD injections. Administration of IL4-CTx i.t. (500 micro g/kg) either 10 times QD or six injections on alternate days elicited complete responses in 40% of mice with DU145 tumors that were three times larger (67 mm(2)) on initiation of treatments. IL4-CTx appeared to be well tolerated. On the basis of these results, combining i.t. injections of IL4-CTx with systemic administration may provide an effective strategy for treating patients with advanced, refractory prostate cancer.
TRIPLET IMAGE MATCHING FOR AIRBORNE DIGITAL SENSOR ADS 40

3D reconstruction from multiple images is one of the most attractive and challenging research fields in photogrammetry and computer vision. One of the practical applications of 3D reconstruction techniques is automated generation of Digital Surface Models (DSMs) from satellite or airborne images. However, it is not easy to obtain a reliable DSM through image matching mainly due to the complexity of urban environments and lack of adequate information for accurate matching. A recently developed commercial Airborne Digital Sensor ADS40 can provide plentiful information and detailed description of complex urban features. Thus, there is a great demand for development of corresponding new strategies to exploit the abundant information and special characteristics of the new sensor. This study introduces a hierarchical triplet image matching strategy for ADS40.
Nature, nurture, and social development*

It is time to bring nature (genetics) together with nurture (environment) in the study of social development. Following a brief overview of behavioral genetic theory and methods, three examples are described of new genetic research especially relevant to social developmentalists. First, initial research findings on three key domains of social development (attachment, empathy, and social competence) suggest that genetic factors contribute to individual differences in social development. Second, research on widely used measures of social environment implicates a genetic contribution, which opens up new directions for research at the interface of nature and nurture in social development. Third, by the turn of the century, it is predicted that behavioral genetic research will be conducted using DNA markers that assess genetic variation among individuals directly rather than resorting to indirect estimates based on twin and adoption methods. This will revolutionize behavioral genetic research and make it more accessible and applicable to developmentalists. As a first step in the direction of behavioral genetics, social developmentalists are encouraged to include siblings in their research.

Adaptive channel estimation in DS-CDMA systems

The accuracy of channel estimation (CE) significantly aects the performance of the coherent rake receiver in DS-CDMA systems. It is desirable to employ a CE scheme that can provide good estimation performance and fast tracking the channel fading with reduced complexity. Such a CE scheme needs to employ a so-called channel estimation filter (CEF) that can eectively reduce the noise eect according to the channel condition. In this paper, we consider the use of adaptive channel estimators that employ a moving average (MA) FIR filter as the CEF. Numerical results show that the use of adaptive MA FIR CEF for pilot based and hybrid CE schemes can provide a performance similar to the use of Wiener CEF, while significantly reducing the implementation complexity.
Health Related Quality of Life among Omani Men and Women with Type 2 Diabetes

The aim of this study was to explore predictors of health related quality of life (HRQoL) among men and women with type 2 diabetes. This cross-sectional descriptive study consisted of a random sample of 300 adults with type 2 diabetes in a selected public hospital. Euro-QoL and Revised Summary of Diabetes Self-Care Activities scales were used to collect data between January and June 2010. Schooling and ability to manage positively were highly significant predictors of quality of life (QoL) among women as compared to men. Age, prevention of activities of daily living and knowledge/management of diabetes were significant predictors of Health state among women as compared to men. Findings demonstrate that 30.6% (versus 35.7%) of the variance in the total QoL and 14% (versus 23%) of the variance in health state could be explained by personal and clinical characteristics among women and men, respectively. The study underlines the importance for nurse educators to assess HRQoL among men and women and to develop effective self-care management strategies based on personal and clinical characteristics.
Simple scaling of photosynthesis from leaves to canopies without the errors of big‐leaf models

In big-leaf models of canopy photosynthesis, the Rubisco activity per unit ground area is taken as the sum of activities per unit leaf area within the canopy, and electron transport capacity is similarly summed. Such models overestimate rates of photosynthesis and require empirical curvature factors in the response to irradiance. We show that, with any distribution of leaf nitrogen within the canopy (including optimal), the required curvature factors are not constant but vary with canopy leaf area index and leaf nitrogen content. We further show that the underlying reason is the difference between the time-averaged and instantaneous distributions of absorbed irradiance, caused by penetration of sunflecks and the range of leaf angles in canopies. These errors are avoided in models that treat the canopy in terms of a number of layers ‐ the multi-layer models. We present an alternative to the multi-layer model: by separately integrating the sunlit and shaded leaf fractions of the canopy, a single layered sun/shade model is obtained, which is as accurate and simpler. The model is a scaled version of a leaf model as distinct from an integrative approach.
FLEP: Enabling Flexible and Efficient Preemption on GPUs

GPUs are widely adopted in HPC and cloud computing platforms to accelerate general-purpose workloads. However, modern GPUs do not support flexible preemption, leading to performance and priority inversion problems in multi-tasking environments. In this paper, we propose and develop FLEP, the first software system that enables flexible kernel preemption and kernel scheduling on commodity GPUs. The FLEP compilation engine transforms the GPU program into preemptable forms, which can be interrupted during execution and yield all or part of the streaming multi-processors (SMs) in the GPU. The FLEP runtime engine intercepts all kernel invocations and determines which kernels and how those kernels should be preempted and scheduled. Experimental results on two-kernel co-runs demonstrate up to 24.2X speedup for high-priority kernels and up to 27X improvement on normalized average turnaround time for kernels with the same priority. FLEP reduces the preemption latency by up to 41% compared to yielding the whole GPU when the waiting kernels only need several SMs. With all the benefits, FLEP only introduces 2.5% runtime overhead, which is substantially lower than the kernel slicing approach.
Systems toxicology approaches enable mechanistic comparison of spontaneous and cigarette smoke-related lung tumor development in the A/J mouse model

ABSTRACT The A/J mouse is highly susceptible to lung tumor induction and has been widely used as a screening model in carcinogenicity testing and chemoprevention studies. However, the A/J mouse model has several disadvantages. Most notably, it develops lung tumors spontaneously. Moreover, there is a considerable gap in our understanding of the underlying mechanisms of pulmonary chemical carcinogenesis in the A/J mouse. Therefore, we examined the differences between spontaneous and cigarette smokerelated lung tumors in the A/J mouse model using mRNA and microRNA (miRNA) profiling. Male A/J mice were exposed whole-body to mainstream cigarette smoke (MS) for 18 months. Gene expression interaction term analysis of lung tumors and surrounding nontumorous parenchyma samples from animals that were exposed to either 300 mg/m3 MS or sham-exposed to fresh air indicated significant differential expression of 296 genes. Ingenuity Pathway Analysis® (IPA®) indicated an overall suppression of the humoral immune response, which was accompanied by a disruption of sphingolipid and glycosaminoglycan metabolism and a deregulation of potentially oncogenic miRNA in tumors of MS-exposed A/J mice. Thus, we propose that MS exposure leads to severe perturbations in pathways essential for tumor recognition by the immune system, thereby potentiating the ability of tumor cells to escape from immune surveillance. Further, exposure to MS appeared to affect expression of miRNA, which have previously been implicated in carcinogenesis and are thought to contribute to tumor progression. Finally, we identified a 50-gene expression signature and show its utility in distinguishing between cigarette smoke-related and spontaneous lung tumors
Engaging with parents: the relationship between school engagement efforts, social class, and learning

Using data from the U.S. Department of Education's (2000) Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 (ECLS-K), this study investigates the relationship between school efforts to engage parents, average socioeconomic status (SES) of families within a school, and kindergarteners' end-of-year reading and mathematics achievement. Drawing from Epstein's (2001) parent involvement framework, the 4 types of engagement efforts explored are intended to promote communication, parent volunteering, parent influence in school decision making, and parenting skills. We apply multilevel methods to explore the impact of schools' efforts to engage parents on student achievement. Our findings indicate certain types of school efforts to engage parents influence achievement. Depending on average school SES, efforts to promote volunteering has a differential impact on reading achievement, efforts to involve parents in school decision making has a differential impact on mathematics achievement, and efforts to increase communication and promote parenting skills have a differential impact on reading and mathematics achievement.
