Authors: Nagasawa Kenichiro , Honjoh Masato , Miyake Hiroaki , Watanabe Rikio , Tanaka Yasuhiro , Takada Tatsuo 
Published: June 2010

AbstractCharge accumulations in electron‐beam (e‐beam)‐irradiated polymers are investigated by observing them using the pressure wave propagation method. The purpose of our research work is to measure the charge distribution in e‐beam‐irradiated dielectric materials for spacecrafts. We have been developing a system for measuring such a charge distribution in dielectric materials. Using this system, we tried to measure the charge distribution in various typical polymers (poly(ethylene terephthalate), polystyrene, low‐density polyethylene) under e‐beam irradiation. As a result, it is found that charging characteristics of insulating material is strongly influenced by the existence of benzene ring in the molecular architecture.

Two‐dimensional Numerical Simulation on the MHD Flow Behavior in a Pulse‐Detonation‐Driven MHD Electrical Power Generator
Authors: Matsumoto Masaharu , Murakami Tomoyuki , Okuno Yoshihiro 
Published: June 2010

AbstractThe magnetohydrodynamic (MHD) flow behavior in a pulse‐detonation‐driven Faraday‐type linear MHD electrical power generator with a converging–diverging nozzle connected to a linear pulse‐detonation tube has been examined by time‐dependent two‐dimensional numerical simulations. Cesium‐seeded stoichiometric hydrogen‐air mixture as the working gas is detonated under atmospheric pressure in the generator. The two‐dimensional temporal evolutions of the propagating detonation wave and the subsequent supersonic flow in the generator are successfully revealed, which result in two peaks of the power output against time. The first peak, provided by the propagation of the detonation wave, hardly deteriorates even in the continuous electrode configuration because of a low Hall parameter due to the high pressure behind the detonation wave front. Such a robust detonation wave, however, can be moderated under a strong MHD interaction. In the supersonic flow following the propagation of the detonation wave, the Hall parameter can be high enough to affect the performance. Thus, if continuous electrodes are used, the second peak shrinks owing to Hall effect, as is well known in the conventional MHD power generator.

A Proposal of User Authentication Infrastructure for Next‐Generation Telematics
Authors: Umezawa Katsuyuki , Susaki Seiichi , Kashiyama Masamori , Tezuka Satoru 
Published: June 2010

AbstractTo receive a telematics service, it must first be authenticated, and each automobile (or car navigation system) has typically to be linked to a particular vehicle owner who could authenticate such services. However, an increasing number of drivers use cars that are rented, leased, or obtained through a car‐sharing program; in such cases, the present form of car authentication is insufficient. A better system would authenticate the individual who is using a car at a particular time, but is not necessarily the owner. In this paper, we propose a personal authentication infrastructure for next‐generation telematics. Copyright © 2010 Institute of Electrical Engineers of Japan. Published by John Wiley & Sons, Inc.
A Hybrid EDA for Protein Folding Based on HP Model
Authors: Chen Benhui , Hu Jinglu 
Published: June 2010

AbstractProtein structure prediction (PSP) is one of the most important problems in computational biology. This paper proposes a novel hybrid estimation of distribution algorithm (EDA) to solve the PSP problem on HP model. First, a composite fitness function containing the information of folding structure core (H‐core) is introduced to replace the traditional fitness function of HP model. The proposed fitness function is expected to select better individuals for the probabilistic model of EDA. Second, local search with guided operators is utilized to refine the found solutions for improving the efficiency of EDA. Third, an improved backtracking‐based repairing method is proposed to repair invalid individuals sampled by the probabilistic model of EDA. It can significantly reduce the number of backtracking searching operation and the computational cost for a long‐sequence protein. Experimental results demonstrate that the proposed method outperform the basic EDA method. At the same time, it is very competitive with other existing algorithms for the PSP problem on lattice HP models. Copyright © 2010 Institute of Electrical Engineers of Japan.

xBCI: A Generic Platform for Development of an Online BCI System
Authors: Susila I Putu , Kanoh Shin'ichiro , Miyamoto Ko‐ichiro , Yoshinobu Tatsuo 
Published: June 2010

AbstractA generic platform for realizing an online brain–computer interface (BCI) named xBCI was developed. The platform consists of several functional modules (components), such as data acquisition, storage, mathematical operations, signal processing, network communication, data visualization, experiment control, and real‐time feedback presentation. Users can easily build their own BCI systems by combining the components on a graphical‐user‐interface (GUI) based diagram editor. They can also extend the platform by adding components as plug‐ins or by creating components using a scripting language. The platform works on multiple operating systems and supports parallel (multi‐threaded) data processing and data transfer to other PCs through a network transmission control protocol/internet protocol or user datagram protocol (TCP/IP or UDP). A BCI system based on motor imagery and a steady‐state visual evoked potential (SSVEP) based BCI system were constructed and tested on the platform. The results show that the platform is able to process multichannel brain signals in real time. The platform provides users with an easy‐to‐use system development tool and reduces the time needed to develop a BCI system. Copyright © 2010 Institute of Electrical Engineers of Japan.

Microfluidic transport in magnetic MEMS and bioMEMS
Authors: Ganguly Ranjan , Puri Ishwar K. 
Published: June 2010

AbstractMagnetic materials, such as ferrimagnetic and ferromagnetic nanoparticles and microparticles in the form of ferrofluids, can be advantageously used in micro‐electro‐mechanical systems (MEMS) and bioMEMS applications, as they possess several unique features that provide solutions for major microfluidic challenges. These materials come with a wide range of sizes, tunable magnetic properties and offer a stark magnetic contrast with respect to biological entities. Thus, these magnetic particles are readily and precisely maneuvered in microfluidic and biological environments. The surfaces of these particles offer a relatively large area that can be functionalized with diverse biochemical agents. The useful combination of selective biochemical functionalization and ‘action‐at‐a‐distance’ that a magnetic field provides makes superparamagnetic particles useful for the application in micro‐total analysis systems (µ‐TAS). We provide insight into the microfluidic transport of magnetic particles and discuss various MEMS and bioMEMS applications.WIREs Nanomed Nanobiotechnol2010 2 382–399This article is categorized under:Diagnostic Tools > In Vitro Nanoparticle-Based Sensing
Video‐Assisted Thoracoscopic Surgery Lobectomy for Lung Cancer: The Learning Curve
Authors: Zhao Hui , Bu Liang , Yang Fan , Li Jianfeng , Li Yun , Wang Jun 
Published: June 2010

AbstractBackgroundVideo‐assisted thoracoscopic surgery (VATS) lobectomy is an acceptable alternative to open lobectomy for treating early‐stage lung cancer. As with any video‐assisted surgical procedure, there is a learning curve to overcome before becoming proficient. In this study, the outcomes of 90 consecutive VATS lobectomies for lung cancer were evaluated to determine the learning curve for this procedure.MethodsA single group of surgeons performed VATS lobectomy with systematic lymph node dissection in 90 patients with lung cancer between September 2006 and January 2009. The patients were divided equally and chronologically into three groups: group A, group B, and group C; group A was the earliest group of patients treated. Clinical data were collected. The operative time, blood loss, number of dissected mediastinal lymph nodes and nodal stations, conversion rate to thoracotomy, postoperative complications, duration of chest drainage, and hospital stay duration were compared between the three groups.ResultsThere were no differences between the three groups with respect to age, gender, size of tumor, pathological stage, and operative procedure. The operative time and blood loss were significantly lower in groups B and C than in group A (P< 0.01); however, there were no differences between groups B and C. There were no differences among the groups in the number lymph nodes harvested, conversion rate, postoperative complications, duration of chest drainage, or hospital stay duration.ConclusionsA learning curve for VATS lobectomy existed in this series. The surgeon became more proficient after 30–60 cases and was able to perform the procedure with decreased blood loss and operative time.
Microemulsion Systems with Rhodium Tris(3‐sulfophenyl)phosphine Trisodium Salt Complex for Product Isolation and Catalyst Recycling in the Hydrogenation of Dimethyl Itaconate
Authors: Milano‐Brusco Juan S. , Touitou Jamal , Strempel Verena , Schomäcker Reinhard 
Published: June 2010

AbstractMicroemulsion systems with the nonionic surfactant p‐tert‐octylphenoxy polyethoxyethanol (OP9.5EO), the anionic surfactant dioctyl sulfosuccinate sodium salt (DOSS) and the narrow range nonionic surfactant alkyl polyethylene glycol ether (C10EO5) were used as solvent systems in the catalytic hydrogenation of dimethyl itaconate (DMI) catalysed by the water soluble catalyst complex Rh‐TPPTS in order to achieve product isolation and catalyst recycling. The DOSS systems, which are more sensitive to the substrate and catalyst addition allowed for the hydrogenation to proceed with an initial hydrogenation rate about three times higher than with the nonionic surfactants, when the surfactant concentration was 15 wt%. Systems with 3 wt% surfactant were used in order to accomplish catalyst recycling. With a biphasic DOSS mixture a turnover number (TON) of 1,200 mol of DMI hydrogenated per mol of catalyst (Rh) was obtained in 3 consecutive runs. A three‐phase system for the OP9.5EO mixture allowed the catalyst to be recycled 3 times and a TON of 1,500 in 4 runs was obtained. A TON of 800 in 2 runs was obtained using a three‐phase C10EO5 mixture.

Résumé

Objectifs
Rechercher la présence d’altérations nucléaires ou acrosomiques dans les spermatozoïdes présentant des vacuoles occupant au moins 13 % de la surface de la tête des spermatozoïdes (spermatozoïdes dits de type 3), détectées à l’aide de la technique MSOME (motile sperm organelle morphology examination).

Matériel et méthodes
Notre étude a été effectuée sur des recueils de sperme de 20 hommes infertiles. Une évaluation de l’acrosome par immunomarquage à l’aide d’un anticorps monoclonal antiproacrosine (Mab4D4) a été associée à une détection de la fragmentation de l’ADN par la technique TUNEL. La condensation de la chromatine spermatique a été évaluée par une coloration au bleu d’aniline, et le taux d’aneuploïdie a été déterminé par hybridation in situ en fluorescence (FISH). Une observation des échantillons spermatiques par microscopie électronique à transmission (MET) [sperme entier] et confocale [spermatozoïdes de type 3 isolés] a complété ces analyses. Les résultats ont été comparés entre des spermatozoïdes provenant du sperme entier et des spermatozoïdes de type 3 isolés.

Résultats
Une augmentation significative de la proportion d’acrosomes anormaux a été constatée dans les spermatozoïdes isolés de type 3 par comparaison au sperme entier (77,8 ± 2,49 % vs 70,6 ± 2,62 %). La fragmentation de l’ADN a été observée de manière comparable dans les spermatozoïdes de type 3 et le sperme entier (14,5 ± 3,45 % vs 11,5 ± 1,25%), un défaut de condensation de la chromatine ainsi qu’une augmentation significative du taux d’aneuploïdie ont été retrouvés dans les spermatozoïdes isolés par comparaison à ceux provenant du sperme entier (50,4 ± 3,10 % vs 26,5 ± 2,60 % et 7,8 ± 1,98 % vs 1,3 ± 0,18 %). Les larges vacuoles sont à localisation nucléaire exclusive (MET et microscopie confocale).

Conclusion
Les vacuoles seraient en relation directe avec un défaut de maturation nucléaire survenant au cours de la spermiogenèse.

AbstractWe performed an Internet-based questionnaire survey of the opinions of German-speaking psychiatrists regarding the experiences with the 10th revision of the international classification of mental disorders (chapter F of ICD-10). We received 304 completed questionnaires including more than 500 free-text comments. The responding group was characterized by professionally experienced middle-aged psychiatrists. German-speaking psychiatrists were comparatively content with ICD-10. Most diagnostic categories received a “satisfied” or “very satisfied” rating by the majority of respondents. Negative “goodness of fit” ratings – a possible indicator of the need for revision – were not higher than 50% for any category. Based on free-text entries, neurasthenia was the single diagnostic category most often suggested for deletion in ICD-11. Changes were considered necessary mainly for dementias and personality disorders. Adult attention deficit disorder and narcissistic personality disorder were the two diagnostic categories most frequently suggested to be added as new categories. This study provides valuable information related to perceived clinical utility of the classification, though with a narrow sample. Information about clinicians’ experiences should be combined with scientific evidence for the revision process of ICD-11.
SUFFERING INFERTILITY: THE IMPACT OF INFERTILITY ON WOMEN'S LIFE EXPERIENCES IN TWO NIGERIAN COMMUNITIES
Authors: LARSEN ULLA , HOLLOS MARIDA , OBONO OKA , WHITEHOUSE BRUCE 
Published: June 2010

SummaryThis paper examines the experiences of women with infertility in two Nigerian communities with different systems of descent and historically different levels of infertility. First, the paper focuses on the life experiences of individual women across the two communities and second, it compares these experiences with those of their fertile counterparts, in each community. In doing this, women who are childless are distinguished from those with subfertility and compared with high-fertility women. The research is based on interdisciplinary research conducted among the Ijo and Yakurr people of southern Nigeria, which included a survey of approximately 100 childless and subfertile women and a matching sample of 100 fertile women as well as in-depth ethnographic interviews with childless and subfertile women in two communities: Amakiri in Delta State and Lopon in Cross River State. The findings indicate that while there are variations in the extent to which childlessness is considered to be problematic, the necessity for a woman to have a child remains basic in this region.
Ecology of parasiteSycophilomorphasp. onFicus altissimaand its effect on the fig-fig wasp mutualism

Published: June 2010

SUMMARYFigs and their pollinating wasps are a classic example of an obligate mutualism. In addition, figs are parasitized by a suite of non-mutualistic wasps whose basic ecology is largely undescribed.Sycophilomorpha(subfamily Epichrysomallinae) fig wasps are ovule gallers and the genus contains only 1 described species. An undescribedSycophilomorphaspecies parasitizedFicus altissimaat Xishuangbana, Southwestern China. The wasp was observed ovipositing on the tiny immature figs that were still concealed beneath the involucral bracts. ASycophilomorphawasp oviposited on more than 1 fig and spent long time-periods to lay large clutches on a single fig. The wasps naturally occurred on all 7 sampled trees, but the occurrence of wasps was significantly different among trees, crops and months. These wasps were able to prevent unpollinated figs from being aborted, and their offspring were able to develop in the figs that otherwise had no pollinator wasps or seeds. TheSycophilomorphawasp had a detrimental effect on the fig–fig wasp mutualism. Figs in whichSycophilomorphawasps were present, produced significantly fewer seeds, pollinators and cheaters. However, the abundance ofSycophilomorphain a fig was only significantly negatively correlated with pollinator production and not seed or cheater production. Our study illustrates a previously unknown fig wasp niche and expands our understanding of factors that can affect the fig–fig wasp interaction.
Low secondary transmission of 2009 pandemic influenza A (H1N1) in households following an outbreak at a summer camp: relationship to timing of exposure
Authors: DOYLE T. J. , HOPKINS R. S. 
Published: June 2010

SUMMARYFollowing an outbreak of 2009 pandemic influenza A (H1N1) at a residential summer camp for boys aged 10–16 years, we assessed secondary household transmission of the novel virus after their return home. Of 212 study participants who attended camp, 49 had confirmed or probable influenza for a primary attack rate of 23%. Of 87 exposed household contacts who did not attend camp, only three instances of probable transmission were observed, for a household secondary attack rate of 3·5%. All secondary cases occurred in households where the ill camp attendee returned home 1 day after onset of illness, with an attack rate of 14·3% in household contacts in this category. Returning home after peak infectivity to others and advanced warning prior to reintegration of sick individuals into the household probably contributed to the overall low secondary attack rate observed.
Social fragmentation and economic growth: evidence from developing countries
Authors: OKEDIJI TADE O. 
Published: June 2010

Abstract:This paper proposes a composite measure of ethnic fragmentation, the Social Diversity Index (SDI) to capture inherent multidimensionality not captured in the prevalent Ethno-Linguistic Fractionalization Index (ELF). The SDI more accurately demonstrates the direct effects of hidden diversity values and the extent and corresponding costs of ethnic diversity on economic growth. A comparative empirical analysis of the results from 132 countries employing the SDI and the ELF Index, suggests that the SDI is more robustly correlated with growth, and does a moderately better job of explaining the effect of exogenous static ethnic diversity. However, the empirical effects of ethnic diversity on growth tend to diminish with the inclusion of additional macroeconomic variables.

Abstract
Hoff, A., Frost, H., Ulrich, C., Damalas, D., Maravelias, C. D., Goti, L., and Santurtún, M. 2010. Economic effort management in multispecies fisheries: the FcubEcon model. – ICES Journal of Marine Science, 67: 1802–1810. Applying single-species assessment and quotas in multispecies fisheries can lead to overfishing or quota underutilization, because advice can be conflicting when different stocks are caught within the same fishery. During the past decade, increased focus on this issue has resulted in the development of management tools based on fleets, fisheries, and areas, rather than on unit fish stocks. A natural consequence of this has been to consider effort rather than quota management, a final effort decision being based on fleet-harvest potential and fish-stock-preservation considerations. Effort allocation between fleets should not be based on biological considerations alone, but also on the economic behaviour of fishers, because fisheries management has a significant impact on human behaviour as well as on ecosystem development. The FcubEcon management framework for effort allocation between fleets and fisheries is presented, based on the economic optimization of a fishery's earnings while complying with stock-preservation criteria. Through case studies of two European fisheries, it is shown how fishery earnings can be increased significantly by reallocating effort between fisheries in an economically optimal manner, in both effort-management and single-quota management settings.

ABSTRACTAims  Peer substance involvement (PSI) is a robust correlate of adolescent substance use. A small number of genetically informative studies suggest that shared genetic and environmental factors contribute to this association. We examine mechanisms by which PSI influences the etiology of regular substance involvement (RSI), particularly in women.Design  Population‐based cohort study of twin women from the US Midwest.Participants  2176 twin women.Measurements  To examine the relationship between self‐reported PSI during adolescence and a composite RSI representing regular tobacco, alcohol and cannabis use during young adulthood, using genetically informative correlation, moderation and joint correlation‐moderation models.Findings  There was evidence for a significant additive genetic X environment interaction. PSI was moderately heritable (h2 = 0.25). Genetic, shared and non‐shared influences on RSI overlapped with influences on PSI (genetic correlation of 0.43). Even after controlling for these shared genetic influences, RSI was more heritable in those reporting greater PSI.Conclusions  While young women may select peers based on certain dispositional traits (e.g. permissiveness towards substance use), the social milieu constructed by PSI does modify the architecture of increased RSI in those individuals with increasing levels of PSI being associated with stronger expression of heritable influences.
