Power control with QoS constraints in WSN using game theoretic approach

The major issue in wireless sensor network (WSN) is the power control since it is impossible to recharge or replace the batteries of the sensors. The sensors transmit at high power to make its transmission successful. Transmitting at high power not only reduces the lifetime of the nodes and that of the network, it also introduces excessive interference. Therefore, every node should transmit at minimal power while satisfying the quality of service (QoS) requirements. This paper proposes a power control game with error control coding (ECC) while considering the QoS requirements. The performance of the power control game satisfying QoS delay constraints with Reed Solomon (RS) and Multivariate Interpolation Decoded RS code (MIDRS) code for WSN is evaluated in terms of bit error rate (BER), throughput and delay.
Structural relationships between clathrin assembly proteins from the Golgi and the plasma membrane.

We have established by peptide mapping and immunochemical analysis of purified clathrin assembly protein preparations from bovine brain, that the cluster of components of mol. wt 100‐120 kd fall into four classes, which we term alpha, beta, beta‘ and gamma. The beta and beta’ proteins are immunologically related and generate a series of common tryptic peptides. The same criteria reveal no such homologies between the alpha, beta(beta‘) and gamma polypeptides. The so‐called HA‐II assembly protein group contains equimolar amounts of alpha and beta class polypeptides, which are shown to interact with each other. In the HA‐I group assembly protein complex gamma and beta’ class polypeptides form a stoichiometric complex. Immunofluorescence microscopy reveals that the HA‐I complex is specifically associated with clathrin‐coated membranes in the Golgi region of cultured cells, whereas the HA‐II complex appears to be restricted to coated pits on the plasma membrane. The data lead to the tentative conclusion that the clathrin assembly proteins are involved in the recognition of the intracellular targets by uncoated vesicles.
Terminal Restriction Fragment Length Polymorphism Analysis for Human Fecal Microbiota and Its Application for Analysis of Complex Bifidobacterial Communities

Terminal restriction fragment length polymorphism (T‐RFLP) analysis was used to characterize and compare human fecal microbiota among individuals. T‐RFLP patterns of fecal 16S ribosomal DNA (rDNA) PCR products from three adults revealed host‐specific bacterial communities and were in good agreement with those reported in our previous study. In addition, we applied T‐RFLP analysis for the analysis of complex bifidobacterial communities in human fecal samples. The developed method based on Bifidobacterium genus‐specific PCR and T‐RFLP could identify more than one bifidobacterial species. T‐RFLP patterns of Bifidobacterium genus‐specific PCR products from the fecal samples were host‐specific as well as those of fecal 16S rDNA PCR products. These results were confirmed by PCR‐denaturing gradient gel electrophoresis (DGGE) with primers specific for the genus Bifidobacterium and Bifidobacterium species‐ and group‐specific PCR. Our study demonstrates that T‐RFLP analysis is useful for assessment of the diversity of the human fecal microbiota and rapid comparison of the community structure among individuals, and that the applied method is useful for rapid and sensitive analysis of bifidobacterial community.
Finite Control Set–Model Predictive Control with Modulation to Mitigate Harmonic Component in Output Current for a Grid-Connected Inverter under Distorted Grid Conditions

This paper presents an improved current control strategy for a three-phase grid-connected inverter under distorted grid conditions. In terms of performance, it is important for a grid-connected inverter to maintain the harmonic contents of inverter output currents below the specified limit even when the grid is subject to harmonic distortion. To address this problem, this paper proposes a modulated finite control set–model predictive control (FCS-MPC) scheme, which effectively mitigates the harmonic components in output current of a grid-connected inverter. In the proposed scheme, the system behavior in the future is predicted from the system model in the discrete-time domain. Then, the cost function is selected based on the control objective of system. This cost function is minimized during the optimization process to determine the control signals that minimize the cost function. In addition, since the proposed scheme requires pure sinusoidal reference currents in the stationary frame to work successfully, the moving average filter (MAF) is employed to enhance the performance of the traditional phase lock loop (PLL). Due to the control performance of the FCS-MPC scheme as well as the harmonic disturbance rejection capability of the MAF-PLL, the proposed scheme is able to suppress the harmonic distortion even in the presence of distorted grid condition, while retaining fast transient response. Comparative simulation results of different controllers verify the effectiveness of the proposed control scheme in compensating the harmonic disturbance. To validate the practical feasibility of the proposed scheme, the whole control algorithm is implemented on a 32-bit floating-point digital signal processor (DSP) TMS320F28335 to control a 2 kW three-phase grid-connected inverter. As a result, the proposed scheme is a promising approach toward improving the current quality of a grid-connected inverter under distorted grid conditions.
[A meta-analysis of radiofrequency ablation for early hepatocellular carcinoma].

OBJECTIVE To compare the effectiveness and safety of radiofrequency ablation (RFA) with other therapeutic methods for patients with early hepatocellular carcinoma (HCC). METHODS Randomized clinical trials (RCTs) which compared the efficacy or safety of RFA with other therapeutic methods for primary hepatocellular carcinoma in Cochrane library, EMBASE, PubMed, OVID and CBM were searched. Trials were considered of high quality if methodological quality score was 3 or more according to Jadad standard. Statistical heterogeneity between trials was evaluated by STATA 9.0 and considered to exist when P < 0.1. Heterogeneity of the included articles was tested and used to select proper effective model for calculation. Sensitivity analysis was performed and publication bias was investigated through visual inspection of funnel plots and Egger regression model. RESULTS Six RCTs including 862 cases were analyzed. As compared with other therapeutic approaches, RFA significantly increased 3-year overall survival rate and reduced local recurrence rate of early hepatocellular carcinoma; the total OR were 2.06 (95% CI being 1.54-2.77, P = 0.000) and 0.40 (95% CI being 0.28-0.57, P = 0.000) respectively. As compared with other therapeutic approaches, the total OR of new HCC recurrence rates, extrahepatic metastasis rate and major complications in patients with HCC treated with RFA were 0.92 (95% CI being 0.68-1.24), 0.98 (95% CI being 0.30-3.22), 1.35 (95% CI being 0.49-3.77) respectively, showing no significant differences (P > 0.05). Inspection of the funnel plots for all outcome measures did not reveal evidence of publication bias (P = 0.670, 0.160, 0.884, 0.087, 0.317, respectively, by Egger regression model). CONCLUSIONS RFA is superior to other treatment methods with respect to local recurrence and 3 year overall survival in early HCC and is the preferred therapeutic method for small HCC because it is minimally invasive, simple and convenient.
Sphingosine‐1‐phosphate is released by cerebellar astrocytes in response to bFGF and induces astrocyte proliferation through Gi‐protein‐coupled receptors

The mitogenic role of sphingosine‐1‐phosphate (S1P) and its involvement in basic fibroblast growth factor (bFGF)‐induced proliferation were examined in primary cultures of cerebellar astrocytes. Exposure to bFGF resulted in a rapid increase of extracellular S1P formation, bFGF inducing astrocytes to release S1P, but not sphingosine kinase, in the extracellular milieu. The SK inhibitor N,N‐dimethylsphingosine inhibited S1P release as well as bFGF‐induced growth stimulation. S1P application in quiescent astrocytes caused a dose‐dependent increase in DNA synthesis. This gliotrophic effect was induced by a brief exposure to low nanomolar S1P, mimicked by the S1P receptor agonist dihydro‐S1P, and inhibited by pertussis toxin (PTX), an inactivator of Gi/Go‐proteins. S1P also induced activation of extracellular signal‐regulated kinase that was inhibited again by PTX. Moreover, the S1P lyase inhibitor 4‐deoxypyridoxine induced the cellular accumulation of S1P but did not affect DNA synthesis. These results support the view that S1P exerted a mitogenic effect on cerebellar astrocytes extracellularly, most likely through cell surface S1P receptors. In agreement, mRNAs for S1P1, S1P2, and S1P3 receptors are expressed in cerebellar astrocytes (Anelli et al., 2005. J Neurochem 92:1204–1215). Ceramide, a negative regulator of astrocyte proliferation and down‐regulated by bFGF (Riboni et al., 2002. Cerebellum 1:129–135), efficiently inhibited S1P‐induced proliferation. The S1P action appears to be part of an autocrine/paracrine cascade stimulated by bFGF and, together with ceramide down‐regulation, essential for astrocytes to respond to bFGF. The results suggest that S1P and bFGF/S1P may play an important role in physiopathological glial proliferation, such as brain development, reactive gliosis and brain tumor formation. © 2006 Wiley‐Liss, Inc.
Influence of SNS User Innovativeness and Public Individuation on SNS Usage Patterns and Social Capital Development: The Case of Facebook

ABSTRACT This paper studies the correlation between users’ psychological traits and their social network sites (SNS) usage patterns, and the correlation between SNS usage patterns and the development of social capital as it relates to Facebook. Individual personality traits, including user innovativeness and public individuation, are proposed to be positively correlated with SNS usage patterns such as usage rate and diversification of use. This study specifically classifies social capital into two types—bridging vs. bonding—based on Social Capital Theory, and examines the correlation between SNS usage patterns and social capital development. To investigate the proposed hypotheses of this study, SNS users in Korea were surveyed and a structural equation model was used to analyze and verify the hypotheses. The results showed that users exhibiting both a high degree of innovativeness and public individuation use SNS more frequently and in more diverse ways than users who exhibited lower degrees of innovativeness and public individuation. It was also found that SNS usage patterns are correlated with social capital. The results of this study contribute to SNS-related research work as this study focuses on the development of social capital—a key concept behind the creation and use of SNS—and allows for a deeper understanding of how the psychological traits of individual users affect SNS usage patterns and the development of social capital. This study also offers insights to the corporate sector by providing practical guidelines on how to utilize SNS more effectively.
Nature of the Kanagawa phenomenon of Vibrio parahaemolyticus

In a study of the Kanagawa phenomenon of Vibrio parahaemolyticus, both Kanagawa-positive and -negative strains were found to produce hemolytic factors that could not be differentiated on Wagatsuma blood agar. The presence of fermentable carbohydrates in media containing high concentrations of NaCl promoted the growth of V. parahaemolyticus and resulted in a marked decrease in medium pH and increased hemolysin production. The Kanagawa hemolysis of test strains differed according to the carbohydrates added. Clearly defined Kanagawa hemolysis was observed in blood agars of high salt content, but the distinction was lost in media containing 3% NaCl. From the results of this study, the Kanagawa hemolysis was interpreted as an expression of quantitative difference in hemolysin production, a conclusion that is clearly demonstrated on special blood agar of high salt content.
Productivity & Play: A First-Person Shooter for Fast and Easy Scene Design

Building 3D scenes for games can be a difficult task, especially for beginners and other non-experts wanting to contribute their own ideas in an easy way. Tools for map or world creation are often complex to understand and use, don't support the creative process of building a scene, and decouple design from player experience. To overcome these problems, we present a First-Person Shooter (FPS) game for level creation using game mechanics for all tasks, making the process more easy and enjoyable while also providing direct experience of the work from a player's point of view. We evaluated our approach in a preliminary study where we compared our game to a simplified version of the Unity editor, representing generic world building tools, and found that users enjoy the our game, find it more usable, and feel more creative.
Reputation, framing strategies and user's choice of content on the Web: an empirical study

Current trends on the Internet indicate an increasing supply of content from anonymous users (e.g. blogs), which may become popular among website visitors. Motivated by these Internet trends, the present study explores the tradeoffs between the source's reputation and the way content is displayed or offered on the web page as well as the effects of both on the Internet user's choice of information services. The study builds upon behavioral economics and focuses on the interaction between background and local context effects on the individual's choice. In particular, the study investigates the tradeoffs between the source's reputation, representing the background context and the provision of enriched content (e.g. source bundled with a picture or a video) representing local context. The research involved a set of experiments based on hypothetical choice or matching tasks. The main findings indicate that there are significant interaction effects between reputation and enriched content, in the form of content related pictures, video and users' recommendations, which affect the user's choice of information services.

Cognitive Maps in Rats and Robots

More is known of the navigation skills of mice and rats than of any other vertebrate. The discovery of place cells (cells whose firing rate correlates with the spatial position of the animal) in the rat’s hippoc ampus has inspired various attempts to model these cells. This work presents one such model which has been optimized on simulated autonomous agents and implemented on a mobile robot which learns to navigate within its environment through exploration using vision as its main sensory modal ity. The artificial mouse robot aMouse, a mobile robot with active whiskers and omnidirectional vision, is presented as an ideal robotic platform to study rodent navigation. The visual field of the robot is similar to the large visual field of rats and mice, and its whisker system uses real rat whiskers for tex ture recognition. The paper suggests how tactile information from the active whisker array on the robot can be used as an additional sensory modality for the place cell model described earlier.
Anopheles rivulorum, a vector of human malaria in Africa

Malaria transmission in tropical Africa is dominated by three widespread vectors: Anopheles arubiensis Patton, An.garnbiae Giles and An,funesfus Giles. Other locally important vectors include An.me1n. r Theobald, An.merus Donitz, An.rnoucheti Evans and An.nili (Theobald). Occasional specimens of about a dozen more Afrotropical Anopheles spp. have been found carrying sporozoites. putatively of human malaria (Gillies & De Meillon. 1968: Gillies & Coetzee, 1987). Since most of these iecondary vectors are exophilic, they might sustain malaria transmission after the control or elimination of the main endophilic vectors. Furthermore. reduction of An,funestus which is very endophilic and anthropophilic -can lead to upsurge of other memhers of the,finestus group that are more exophilic (Gillies & Smith, 1960). Following insecticidal house-spraying, for example, An.pnrmsis Gillies increased at Malindi on the Kenya Coast (Gillies & Furlong. 1964); likewise in Transvaal, South Africa, An.vaneedeni Gillies & Coetzee increased and was suspected of maintaining the transmission of malaria in the absence of the usual vector \pecies (De Meillon et al., 1977: Smith er al., 1977). Apart from An. ,fitnesfu.y Giles sensu stricro, the most widespread member of this species group is An.rivulorum Leeson. Number3 of An.rirulorurn have been found to increase after the elimination of An.funesfus S.S. by house-spraying with residual insecticide (Gillies & Smith, 1960). The possibility that Anriwlorurn may assume some importance in malaria transmission under these circumstances has not been studied previously. We found sporozoite-positive An.rivulorurn in Tanzanian villages where this species remained prevalent despite malaria vector control by means of house-spraying (Matola ef al., 1990) or the use of pyrethroid-impregnated mosquito nets (Magesa et al. 1991). Mosquitoe\ were collected in 1987-90 from four villages close to the tuwn of Muheza (50"lI'S. 38'50'E), some 50 km inland from the Tanzanian coast at Tanga. The area is holoendemic for malaria due to perennial transmission of Pfalciparurn by the vectors An.garnbiue S . S . and An. funestus S.S. Mosquitoes were obtained from resting-sites close to cattle corrals and pit shelters during the day time: all-night peridomiciliary landing catches on human bait: knock-down spray-collections indoors; CDC light
Flaxseed Alone or in Combination with Tamoxifen Inhibits MCF-7 Breast Tumor Growth in Ovariectomized Athymic Mice with High Circulating Levels of Estrogen

Flaxseed (FS) is rich in mammalian lignan precursors and α-linolenic acid, which have been suggested as having anticancer effects. Previous studies have shown that 10% FS inhibits the growth of human estrogen–dependent breast cancer (MCF-7) in athymic mice, and it enhances the inhibitory effect of tamoxifen (TAM). This study determined whether the effect of FS, alone or in combination with TAM, is dose dependent, and it explored the potential mechanism of action. Ovariectomized athymic mice with estradiol (E2) supplementation (1.7 mg/pellet, 60-day release) and established MCF-7 tumors were treated with basal diet control (0FS), 5% FS (5FS), 10% FS (10FS), and TAM (TAM/ 0FS; 5 mg/pellet, 60-day release), alone or in combination (TAM/ 5FS and TAM/10FS) for 8 weeks. Compared with control, 5FS and 10FS significantly inhibited tumor growth by 26% and 38%, respectively. TAM/0FS had an effect similar to the 10FS. TAM/ 5FS and TAM/10FS, respectively, induced significant 48% and 43% reductions in tumor size compared with 0FS, and 18% and 10% reductions compared with TAM/0FS. The relative uterine weight was significantly lower in all TAM groups compared with the control. The reduction of tumor growth resulted from decreased cell proliferation and increased cell apoptosis. TAM/ 5FS caused a significantly higher expression of estrogen receptor-α (ERα) compared with 5FS and TAM/0FS, whereas TAM/10FS had a higher ERα than 10FS and TAM/0FS. Compared with the control, progesterone receptor (PgR) expression was significantly reduced in all treatment groups, but insulin-like growth factor-1 (IGF-1) expression was reduced only by 10FS, TAM/5FS and TAM/10FS. Tumor cell proliferation was significantly positively associated with expression of PgR and IGF-1 and negatively associated with apoptosis and ERα. Apoptosis was only associated with ERα. In conclusion, FS inhibited MCF-7 tumor growth in a dose-dependent manner and enhanced the inhibitory effect of TAM due to the modulation of ER and growth factor signal transduction pathways.
Vaccination of goats with recombinant galectin antigen induces partial protection against Haemonchus contortus infection

The efficacy of vaccination against Haemonchus contortus infection with two recombinant proteins, rHco‐gal‐m and rHco‐gal‐f, was studied in 9–10‐month‐old goats. Vaccination with 100 µg protein reduced faecal egg output and worm burdens by 37·25% and 41·1%, respectively. Corresponding reductions with 200 µg protein were 48·03% and 46·19%. Vaccinated groups had significantly higher IgG levels than the negative and positive controls. Significant negative correlations were detected between IgG level, mucosal homogenate IgA concentration, haemoglobin and abomasal worm burden at necropsy. By contrast a positive correlation was found between the percentage of B cells, monocytes and abomasal worm burden. These findings suggested that vaccination with a combination of recombinant rHco‐gal‐m/f proteins had a role in protecting goats against H. contortus infection.
NHS and Community Care Act 1990 and discharges from hospital to private residential and nursing homes

The NHS and Community Care Act 1990 requires social services departments to assess elderly inpatients who may need help after discharge from hospital and to use a care management process to arrange their care.1 One of the main aims of the act was to reverse the “perverse incentive” for people to be cared for in private residential and nursing homes. The act tried to achieve this aim by ensuring that money that was originally available through social security to people in private homes who received income support was transferred to social services departments; social services could use the money to maintain people in their own homes. Concern was expressed that the new assessment and care management might delay patients' discharge from hospital,2 and such delays have been reported. …
Electrostatic-spray ionization mass spectrometry sniffing for perfume fingerprinting.

RATIONALE The perfume market is growing significantly, and it is easy to find imitative fragrances of probably all types of perfume. Such imitative fragrances are usually of lower quality than the authentic ones, creating a possible threat for perfume companies. Therefore, it is important to develop efficient chemical analysis techniques to screen rapidly perfume samples. METHODS Electrostatic-spray ionization (ESTASI) was used to analyze directly samples sprayed or deposited on different types of paper. A linear ion trap mass spectrometer was used to detect the ions produced by ESTASI with a modified extended transfer capillary for 'sniffing' ions from the paper. RESULTS Several commercial perfumes and a model perfume were analyzed by ESTASI-sniffing. The results obtained by paper ESTASI-MS of commercial fragrances were compared with those obtained from ESI-MS. In addition, a commercial fragrance was first nebulized on the hand and then soaked up by blotting paper, which was afterwards placed on an insulating plate for ESTASI-MS analysis. Analysis of peptides and proteins was also performed to show that the paper ESTASI-MS could be used for samples with very different molecular masses. CONCLUSIONS Paper ESTASI-MS yields a rapid fingerprinting characterization of perfume fragrances, avoiding time-consuming sample-preparation steps, and thereby performing a rapid screening in a few seconds.
