Effect of isometric handgrip exercise training on resting blood pressure in normal healthy adults.

INTRODUCTION The aim of the present study was to study the effect of isometric handgrip (IHG) exercise training on resting blood pressure in normal healthy volunteers. MATERIALS AND METHODS Hand grip spring dynamometer was used for IHG exercise training. A total of 30 normal healthy volunteers in the age group of 20-40 y were enrolled for the study. Exercise training protocol consisted of five 3-min bouts of IHG exercise at 30% of maximum voluntary contraction separated by 5 min rest periods. Exercise was performed 3 times/wk for 10 wk. Subject's blood pressure was measured before and after exercise. RESULT There was a significant reduction in resting blood pressure following 10 wk of exercise training. Both Systolic and Diastolic blood pressure reduced significantly (p<0.001). CONCLUSION IHG exercise training might be a simple, effective, inexpensive and non-pharmacological method in lowering blood pressure.
Comparative transcriptome analysis of nodules of two Mesorhizobium–chickpea associations with differential symbiotic efficiency under phosphate deficiency

Phosphate (Pi) deficiency is known to be a major limitation for symbiotic nitrogen fixation (SNF), and hence legume crop productivity globally. However, very little information is available on the adaptive mechanisms, particularly in the important legume crop chickpea (Cicer arietinum L.), which enable nodules to respond to low-Pi availability. Thus, to elucidate these mechanisms in chickpea nodules at molecular level, we used an RNA sequencing approach to investigate transcriptomes of the nodules in Mesorhizobium mediterraneum SWRI9-(MmSWRI9)-chickpea and M. ciceri CP-31-(McCP-31)-chickpea associations under Pi-sufficient and Pi-deficient conditions, of which the McCP-31-chickpea association has a better SNF capacity than the MmSWRI9-chickpea association during Pi starvation. Our investigation revealed that more genes showed altered expression patterns in MmSWRI9-induced nodules than in McCP-31-induced nodules (540 vs. 225) under Pi deficiency, suggesting that the Pi-starvation-more-sensitive MmSWRI9-induced nodules required expression change in a larger number of genes to cope with low-Pi stress than the Pi-starvation-less-sensitive McCP-31-induced nodules. The functional classification of differentially expressed genes (DEGs) was examined to gain an understanding of how chickpea nodules respond to Pi starvation, caused by soil Pi deficiency. As a result, more DEGs involved in nodulation, detoxification, nutrient/ion transport, transcriptional factors, key metabolic pathways, Pi remobilization and signalling were found in Pi-starved MmSWRI9-induced nodules than in Pi-starved McCP-31-induced nodules. Our findings have enabled the identification of molecular processes that play important roles in the acclimation of nodules to Pi deficiency, ultimately leading to the development of Pi-efficient chickpea symbiotic associations suitable for Pi-deficient soils.
On Security Indices for State Estimators in Power Networks

In this paper, we study stealthy false-data attacksagainst state estimators in power networks. The focus ison applications in SCADA (Supervisory Control and DataAcquisition) systems where measurement data is corrupted bya malicious attacker. We introduce two security indices for thestate estimators. The indices quantify the least effort neededto achieve attack goals while avoiding bad-data alarms in thepower network control center (stealthy attacks). The indicesdepend on the physical topology of the power network and theavailable measurements, and can help the system operator toidentify sparse data manipulation patterns. This informationcan be used to strengthen the security by allocating encryptiondevices, for example. The analysis is also complemented witha convex optimization framework that can be used to evaluatemore complex attacks taking model deviations and multipleattack goals into account. The security indices are finallycomputed in an example. It is seen that a large measurementredundancy forces the attacker to use large magnitudes in thedata manipulation pattern, but that the pattern still can be relatively sparse.
Individualism‐collectivism as an individual difference predictor of organizational citizenship behavior

Though it appears intuitively appealing that individual differences should be related to a person's decision to perform citizenship behaviors, the search for such individual differences has yet to yield clear results. In this study, data were collected to assess the extent of a relationship between individualism–collectivism as a within culture individual difference and self-reports of organizational citizenship behaviors. Results suggest that if an individual holds collectivistic values or norms, he/she would be more likely to perform citizenship behaviors. In addition, this relationship was found to be robust to common method effects and to the effect of the relationship between procedural justice and OCB. Implications for the way collectivistic tendencies within cultures may be used in organizations are discussed.
On the decidability of phase ordering problem in optimizing compilation

We are interested in the computing frontier around an essential question about compiler construction: having a program P and a set M of non parametric compiler optimization modules (called also phases), is it possible to find a sequence s of these phases such that the performance (execution time for instance) of the final generated program P′ is "optimal" ? We prove in this article that this problem is undecidable in two general schemes of optimizing compilation: iterative compilation and library optimization/generation. Fortunately, we give some simplified cases when this problem be-comes decidable, and we provide some algorithms (not necessary efficient) that can answer our main question. Another essential question that we are interested in is parame-ters space exploration in optimizing compilation (tuning optimizing compilation parameters). In this case, we assume a fixed sequence of optimization, but each optimization phase is allowed to have a parameter. We try to figure out how to compute the best parameter values for all program transformations when the compilation sequence is given. We also prove that this general problem is undecidable and we provide some simplified decidable instances.
Wideband Linear-to-Circular Polarization Converters Based on Miniaturized-Element Frequency Selective Surfaces

We introduce a new technique for designing wideband polarization converters based on miniaturized-element frequency selective surfaces (MEFSSs). The proposed structure is a two-dimensionally anisotropic periodic structure composed of arrays of subwavelength capacitive patches and inductive wire grids separated by thin dielectric substrates. The structure is designed to behave differently for field components of the two orthogonal polarizations and transmits a circularly polarized wave once illuminated by a linearly polarized plane wave. Using equivalent circuit models for MEFSSs, a synthesis procedure is developed that can be used to design the polarization converter from its required bandwidth and center frequency of operation. Using this procedure, a prototype of the proposed polarization converter operating within the X-band is designed, fabricated, and experimentally characterized using a free-space measurement system. The measurement results confirm the theoretical predictions and the design procedure of the structure and demonstrate that the proposed MEFSS-based polarization converter operates in a wide field of view of ±45° with a fractional bandwidth of 40%.
Curvature, connected sums, and Seiberg-Witten theory

We consider several differential-topological invariants of compact 4-manifolds which directly arise from Riemannian variational problems. Using recent results of Bauer and Furuta, we compute these invariants in many cases that were previously intractable. In particular, we are now able to calculate the Yamabe invariant for certain connected sums of complex surfaces.
Recommendation under Capacity Constraints

In this paper, we investigate the common scenario where every candidate item for recommendation is characterized by a maximum capacity, i.e., number of seats in a Point-of-Interest (POI) or size of an item's inventory. Despite the prevalence of the task of recommending items under capacity constraints in a variety of settings, to the best of our knowledge, none of the known recommender methods is designed to respect capacity constraints. To close this gap, we extend three state-of-the art latent factor recommendation approaches: probabilistic matrix factorization (PMF), geographical matrix factorization (GeoMF), and bayesian personalized ranking (BPR), to optimize for both recommendation accuracy and expected item usage that respects the capacity constraints. We introduce the useful concepts of user propensity to listen and item capacity. Our experimental results in real-world datasets, both for the domain of item recommendation and POI recommendation, highlight the benefit of our method for the setting of recommendation under capacity constraints.
Creating an academic and technological landscape of service innovation: An analysis of the citation network

It is widely recognized that the concept of service innovation is significant for innovation strategy and economic growth especially in developed countries. However, since the term “service innovation” represents a broad sense, there is not the common understanding about what is service innovation even among experts. In this paper, we create an academic and technological landscape of service innovation from a number of academic publications and patents. Not only creating landscapes, extracting the gap between science and technology can be extract by comparing the major topics. As a result, there were mainly eight clusters in science and twelve in technology. SSME research domain is so interdisciplinary that each of eight is not so strongly related to others. On the contrary, all major patent clusters are IT-related ones. In other words, the scientific outcomes are not applied into industries. This result suggests we need to accelerate applying the scientific outcomes into industries.
High rates of serum selenium deficiency among HIV- and HCV-infected and uninfected drug users in Buenos Aires, Argentina

Abstract Objective To describe the prevalence of low serum Se and determine whether HIV, hepatitis C virus (HCV) and/or the types of drugs used are associated with serum Se in a cohort of infected and uninfected drug users. Design Independent correlates of low serum Se levels based on data collected from food recalls, physical examinations and clinical questionnaires were identified using multivariate regression analysis. Setting Buenos Aires, Argentina Subjects A total of 205 (twenty-five female and 180 male) former and current drug users. Results Drug users had an average serum Se level of 69·8 (sd 32·8) μg/dl, and 82 % were considered deficient (<85 μg/dl). Multivariate analyses found that HIV- and/or HCV-infected individuals had lower mean Se compared with healthy, uninfected drug users (HIV/HCV co-infection: −25·3 μg/l (se 7·6), P = 0·001; HIV alone: −28·9 μg/l (se 6·9), P < 0·001; HCV alone: −19·4 μg/l (se 7·1), P = 0·006). Current and previous drug use was associated with higher serum Se. Cigarette smoking and heavy alcohol consumption were not found to be associated with Se status. Conclusions Low serum Se levels are highly prevalent among drug users in Buenos Aires, Argentina. Se supplementation and/or dietary interventions may be warranted in drug users who are at high risk for HIV and/or HCV infection.
Controllable Printing Droplets for High‐Resolution Patterns

Inkjet printing has attracted wide attention due to the important applications in fabricating biological, optical, and electrical devices. During the inkjet printing process, the solutes prefer to deposit along the droplet periphery and form an inhomogeneous morphology, known as the coffee‐ring effect. Besides, the feature size of printed dots or lines of conventional inkjet printing is usually limited to tens or even hundreds of micrometers. The above two issues greatly restrict the extensive application of printed patterns in high‐performance devices. This paper reviews the recent advances in precisely controlling the printing droplets for high‐resolution patterns and three‐dimensional structures, with a focus on the development to suppress the coffee‐ring effect and minimize the feature size of printed dots or lines. A perspective on the remaining challenges of the research is also proposed.
Callosa gen. n., a new troglobitic genus from southwest China (Araneae, Linyphiidae)

Abstract A new linyphiid genus Callosa gen. n. , with two new species Callosa ciliata sp. n. (♂♀, type species) and Callosa baiseensis sp. n. (♂♀), from southwest China are described. Detailed description of genitalic characters and somatic features is provided, as well as light microscopy and SEM micrographs of each species. Callosa gen. n. was found in caves in Yunnan and Guangxi, and its copulatory organs are similar to those of Bathyphantes and Porrhomma, but differ greatly in details. The monophyly and placement of Callosa gen. n. are supported by the results of molecular analysis.

A top choice performance of 96% is achieved on a database of postal words captured at 212 dpi.
An Application of Brightness Temperature Received from a Ground-based Microwave Radiometer to Estimation of Precipitation Occurrences and Rainfall Intensity

Ground-based microwave radiometers (MWR) provide continuous thermodynamic (temperature, water vapor, and cloud liquid) soundings in the clear and cloudy weather conditions. These profiles can be determined by observing the intensity of the atmospheric radiation at selected frequencies. The MWR used in this study is TP/WVP-3000A, which measures the intensity of radiation at 8 water vapor channels (22-30 ㎓) and 14 oxygen channels (51-59 ㎓) to obtain thermodynamic profiles at National Center for Intensive Observation of severe weather (NCIO) located at Haenam, Korea. In this study, the predictability of precipitation occurrences and the estimation of rainfall intensity were investigated by using the brightness temperature (TB) of the MWR. The averaged differences of TBs in 2 hours before raining were calculated and compared with those of period unrelated with rain. In 2 hours before raining, the pronounced increase of TB was observed in water vapor channels (22-30 ㎓), while TBs in 54-59 ㎓ as oxygen channels were almost remaining constant except for the great increase of TB at 51-52 ㎓ related to cloud liquid water. Performance for forecasts of precipitation occurrences using the preceding increases of TBs at 22.2 ㎓, 30.0 ㎓, and 51.2 ㎓ was improved and better than the 3-hour operational (routine) forecasts. The estimation of rainfall intensity was examined by two simple estimative methods using the linear and the nonlinear regression analyses between rainfall intensity and TBs. Rainfall intensity was estimated by the calculated regression curves of TBs from MWR and compared with observed one by an Optical Rain Gauge (ORG) at the Haenam NCIO. As a result of the verification on forecasting performances, both the linear and the logarithmic regression methods between the observed and the estimated rainfall intensity showed substantially high in Equitable Threat Scores (ETSs) and correlation coefficients.
Sources of Fear of Crime at School

Abstract While policymakers have granted a substantial commitment of resources in order to reduce fear of crime among U.S. school students, the research literature on fear of crime at school is in its infancy. This study investigates whether school security techniques reduce or exacerbate fear of crime among students, net of community and school disorder and student characteristics. Ferraro's (1995) theory of incivilities suggests that students might perceive highly visible security as an incivility, which might increase their fear of crime. Using a nationally representative sample of American school children from the 1993 National Household Education Survey: School Safety and Discipline Component (NHES-SSD), we found that while school security efforts do not predict student fear as well as school disorder and individual student traits, many types of security correspond with a significantly greater likelihood that a student will be worried about crime while none reduce feelings of worry.
FUZZY PARAMETRIC GEOMETRIC PROGRAMMING WITH APPLICATION IN FUZZY EPQ MODEL UNDER FLEXIBILITY AND RELIABILITY CONSIDERATION

An economic production quantity model with demand dependent unit production cost in fuzzy environment has been developed. Flexibility and reliability consideration are introduced in the production process. The models are developed under fuzzy goal and fuzzy restrictions on budgetary cost. The inventory related costs and other parameters are taken as fuzzy in nature. The problem is solved by parametric geometric programming technique. The model is illustrated through numerical example. The sensitivity analyses of the cost function due to different measures are performed and presented graphically.
A Knowledge-Based Approach to Organizing Retrieved Documents

When people use computer-based tools to find answers to general questions, they often are faced with a daunting list of search results or "hits" returned by the search engine. Many search tools address this problem by helping users to make their searches more specific. However, when dozens or hundreds of documents are relevant to their question, users need tools that help them to explore and to understand their search results, rather than ones that eliminate a portion of those results. In this paper, we present DynaCat, a tool that dynamically categorizes search results into a hierarchical organization by using knowledge of important kinds of queries and a model of the domain terminology. Results from our evaluation show that DynaCat helps users find answers to those important types of questions more quickly and easily than when they use a relevance-ranking system or a clustering system.
Social-Behavioral Assessment of At-Risk Early Adolescent Students: Psychometric Characteristics and Validity of a Parent Report Form of the School Social Behavior Scales

The purposes of this investigation were to examine the validity of the Home and Community Social Behavior Scales (HCSBS) for differentiating at-risk and non-at-risk stu dents in grades 6 through 9 and to evaluate psychometric characteristics of this instru ment. Parent ratings of social competence and antisocial behavior on the HCSBS for a group of 160 students who were part of an at-risk pre vention project were compared with those of 107 typical non-at-risk students. These students were all in grades 6 through 9, and the groups were relatively similar in terms of demographic characteristics. The at-risk group was rated as having significantly lower social competence and significantly higher rates of antisocial behavior than the non-at-risk group (p < .0001). Power analyses indicated that these group differences ranged from approximately 1½ to 1 3/4 standard deviations. Item level HCSBS scores were also shown to correctly clas sify the students into their respective groups with a great deal of accuracy (92.37% overall). Internal consistency coefficients of the two HCSBS scales were uniformly high (in the mid .90 range). These results provide new and use ful evidence regarding the significant social behavior problems exhibited by at-risk stu dents, as well as preliminary evidence of the validity and usefulness of the HCSBS. Implications for further research and psychoe ducational assessment practice are discussed.
Interdigitating cell sarcoma: A morphologic, immunohistologic, and enzyme‐histochemical study

A 58‐year‐old man presented with an unusual sarcoma of the cervical lymph node. The tumor also involved the mesenteric lymph node and jejunum. Tumor cells possessed intracytoplasmic S100 protein, Leu‐3a (T4), and HLA‐DR antigens. The neoplastic cells also showed membranous ATPase activity. LeuM1, T6, Leu1, Leu2a, B1, lysozyme, and immunoglobulin were not recognized. Their fine structure was similar to that of interdigitating cells. These data are consistent with derivation from lymph node interdigitating reticulum cell.
Retrograde adenoviral vector targeting of nociresponsive pontospinal noradrenergic neurons in the rat in vivo

The spinal dorsal horn receives a dense innervation of noradrenaline‐containing fibers that originate from pontine neurons in the A5, locus coeruleus (LC), and A7 cell groups. These pontospinal neurons are believed to constitute a component of the endogenous analgesic system. We used an adenoviral vector with a catecholaminergic‐selective promoter (AVV‐PRS) to retrogradely label the noradrenergic neurons projecting to the lumbar (L4–L5) dorsal horn with enhanced green fluorescent protein (EGFP) or monomeric red fluorescent protein (mRFP). Retrogradely labeled neurons (145 ± 12, n = 14) were found in A5‐12%, LC‐80% and A7‐8% after injection of AVV‐PRS‐EGFP to the dorsal horn of L4–L5. These neurons were immunopositive for dopamine β‐hydroxylase, indicating that they were catecholaminergic. Retrograde labeling was optimal 7 days after injection, persisted for over 4 weeks, and was dependent on viral vector titer. The spinal topography of the noradrenergic projection was examined using EGFP‐ and mRFP‐expressing adenoviral vectors. Pontospinal neurons provide bilateral innervation of the cord and there was little overlap in the distribution of neurons projecting to the cervical and lumbar regions. The axonal arbor of the pontospinal neurons was visualized with GFP immunocytochemistry to show projections to the inferior olive, cerebellum, thalamus, and cortex but not to the hippocampus or caudate putamen. Formalin testing evoked c‐fos expression in these pontospinal neurons, suggesting that they were nociresponsive (A5‐21%, LC‐16%, and A7‐26%, n = 8). Thus, we have developed a viral vector‐based strategy to selectively, retrogradely target the pontospinal noradrenergic neurons that are likely to be involved in the descending control of nociception.
