Published: August 2013

ABSTRACTIn this article, a transversal filter with winner‐take‐all variable gain amplifiers is investigated to improve the performance of a feed‐forward equalizer. The proposed equalizer structure with nine gain cells has wide bandwidth and improved voltage headroom, at the same time achieving the low power consumption per gain cell. The proposed equalizer is fabricated in a 0.18 μm CMOS process and shows the successful compensation with 30 and 60 in backplanes with 3 Gbps signal. © 2013 Wiley Periodicals, Inc.

Reduction of mutual coupling between E‐shaped microstrip antennas by using a simple microstrip I‐section
Authors: Ghosh Chandan Kumar , Parui Susanta Kumar 
Published: August 2013

ABSTRACTMutual coupling is an inevitable phenomenon in multielement antenna systems. It can significantly degrade the performance of array systems. A number of works have been done on the suppression of mutual coupling in the recent years. In this article, we propose a simple I‐shaped resonator in between two E‐shaped microstrip antenna elements separated by 0.45λ to reduce the mutual coupling in patch array of antennas. The mutual coupling has been reduced by more than 30 dB by the introduction of this simple I‐shaped resonator on the same plane of the microstrip radiator. We have developed an experimental model that has proven this concept of antenna coupling reduction. Finally, the influence of other antenna parameters on the mutual coupling level has been studied. One may find its application in wireless communication. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2544–2549, 2013
A novel dual‐band bandpass filter using CRLH triangle mushroom structure and DGS

Published: August 2013

ABSTRACTIn this article, a novel dual‐band bandpass filter using composite right/left handed (CRLH) triangle mushroom structure and defected ground structure (DGS) is proposed. The proposed filter uses triangle mushroom structure as the CRLH transmission line to achieve low‐in‐band insertion loss and compact size, and DGS to achieve out‐band rejection. Simulation and measurement results are in good agreement and the good properties mentioned above have been verified. It is proved that CRLH triangle mushroom structure and DGS can be both used to reduce the size of the filter and increase the rejection between the passbands in multipassband filter applications for the first time. This new combination of the two different structures has succeeded in achieving excellent performance. This novel filter can be applied in the microwave circuits and wireless communication systems. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2756–2759, 2013

Authors: Jabbour Georges , O'Loughlin Jennifer , Sabiston Catherine , Tremblay Angelo , Mathieu Marie‐Eve 
Published: August 2013

ObjectiveThis study explores differences in LO rates between pre‐pubertal and pubertal girls of three body weight status groups.MethodsThe sample included 39 pre‐pubertal girls [12 normal‐weight (NW), 12 overweight (OW), and 15 obese (OB)] and 37 pubertal girls [16 NW, 10 OW, and 11 OB]. Following a rest period, the girls performed a graded maximal cycling test. The %LO contribution was computed at each stage.ResultsThe %LO contribution did not differ between NW, OW, or OB pre‐pubertal girls at each exercise stage. In contrast, pubertal OB girls showed a statistically significantly higher %LO contribution at 25, 50, and 75 W stages compared with OW and NW as well as with OB pre‐pubertal girls.ConclusionsOur results demonstrate that entering puberty is a period associated with differentiation in substrate selection in obese girls. A higher %LO contribution may help girls to solicit more fat while performing submaximal exercise.

ObjectiveTo examine the extent to which an intervention using electronic decision support delivered to pediatricians at the point‐of‐care of obese children, with or without direct‐to‐parent outreach, improved health care quality measures for child obesity.Design and MethodsProcess outcomes from a three‐arm, cluster‐randomized trial from 14 pediatric practices in Massachusetts were reported. Participants were 549 children aged 6‐12 years with body mass index (BMI) ≥ 95th percentile. In five practices (Intervention‐1), pediatricians receive electronic decision support at the point‐of‐care. In five other practices (Intervention‐2), pediatricians receive point‐of‐care decision support and parents receive information about their child's prior BMI before their scheduled visit. Four practices receive usual care. The main outcomes were Healthcare Effectiveness Data and Information Set (HEDIS) performance measures for child obesity: documentation of BMI percentile and use of counseling codes for nutrition or physical activity.ResultsCompared to the usual care condition, participants in Intervention‐2, but not Intervention‐1, had substantially higher odds of use of HEDIS codes for BMI percentile documentation (adjusted OR: 3.97; 95% CI: 1.92, 8.23) and higher prevalence of use of HEDIS codes for counseling for nutrition or physical activity (adjusted predicted prevalence 20.3% [95% CI 8.5, 41.2] for Intervention −2 vs. 0.0% [0.0, 2.0] for usual care).ConclusionAn intervention that included both decision support for clinicians and outreach to parents resulted in improved health care quality measures for child obesity.
Terahertz studies of carrier localization in spontaneously forming polar lateral heterostructures
Authors: Metcalfe Grace D. , Hirai Asako , Young Erin C. , Speck James S. , Shen Hongen , Wraback Michael 
Published: August 2013

AbstractWe employ near‐bandgap terahertz emission spectroscopy to study lateral heterostructures resulting from basal plane stacking faults in m ‐plane GaN. The predominant stacking faults have I1 character and behave as an array of spontaneously forming layers comprised of a single cubic stacking sequence within the wurtzite matrix that terminate the spontaneous polarization along the in‐plane c‐axis, leading to strong lateral electric fields. Spectral tuning of femtosecond excitation pulses enables observation of the transition from carrier transport in the continuum to formation of instantaneous dipoles and nonlinear susceptibility associated with both the quantum‐well‐like regions of the cubic layers and polarization‐induced triangular‐like potentials.

Propagation of dilatation and shear waves through a dynamic checkerboard material geometry in 1D space + time
Authors: Sanguinet W.C. , Lurie K.A. 
Published: August 2013

AbstractWe study the propagation of dilatational and shear waves through an isotropic elastic material having the dilatation and shear moduli variable in space and time. Two isotropic materials alternate occupying rectangular cells in 1D space + time producing a double periodic checkerboard material assembly. The materials are assumed to differ in their wave velocities (dilatational and shear) and to have pairwise equal values of wave impedances for each type of wave. We show, however, that, for both types of waves traveling normally to spatial interfaces between the materials, the average velocity of propagation is the same for certain ranges of material and structural parameters. Also, the energy is accumulated in those waves, and such accumulation occurs in very narrow pulses. This is unlike the wave propagation in a uniform static material, where both types of waves propagate at different speeds. The coincidence of average speeds of propagation appears to be due to the checkerboard material geometry. It creates the “plateau effect” within the ranges of material and structural parameters mentioned above [3, 4, 6]. These ranges do not include the purely uniform material. In elastodynamics, the concept of dynamic materials has been previously studied in references [2, 7].

Published: August 2013

AbstractHypophosphatasia (HPP) is an inborn error of metabolism caused by deficiency of the tissue‐nonspecific alkaline phosphatase (TNSALP), resulting in a defect of bone mineralization. Natural substrates for this ectoenzyme accumulate extracellulary including inorganic pyrophosphate (PPi), an inhibitor of mineralization, and pyridoxal 5‐phosphate (PLP), a co‐factor form of vitamin B6. Enzyme replacement therapy (ERT) for HPP by functional TNSALP is one of the therapeutic options. The C‐terminal‐anchorless human recombinant TNSALP derived from Chinese hamster ovary cell lines was purified. TNSALP‐null mice (Akp2‐/‐), an infantile model of HPP, were treated from birth using TNSALP and vitamin B6 diet. Long‐term efficacy studies of ERT consisted of every 3 days subcutaneous or intravenous injections till 28 days old (dose 20 U/g) and subsequently every 3 days intravenous injections for 6 months (dose 10 U/g). We assessed therapeutic effect by growth and survival rates, fertility, skeletal manifestations, and radiographic and pathological finding. Treated Akp2‐/‐ mice grew normally till 4 weeks and appeared well with a minimum skeletal abnormality as well as absence of epilepsy, compared with untreated mice which died by 3 weeks old. The prognosis of TNSALP‐treated Akp2‐/‐ mice was improved substantially: 1) prolonged life span over 6 months, 2) improvement of the growth, and 3) normal fertility. After 6 months of treatment, we found moderate hypomineralization with abnormal proliferative chondrocytes in growth plate and articular cartilage. In conclusion, ERT with human native TNSALP improves substantial clinical manifestations in Akp2‐/‐ mice, suggesting that ERT with anchorless TNSALP is also a potential therapy for HPP.
Maritime safety and the ISM code: a study of investigated casualties and incidents
Authors: Batalden Bjørn-Morten , Sydnes Are Kristoffer 
Published: August 2013

Abstract
In 1993, the International Maritime Organization adopted the International Safety Management (ISM) Code which requires all shipping companies operating certain types of vessels to establish safety management systems. Nevertheless, two decades later, maritime safety remains a concern. This article studies 94 maritime cases investigated by the Maritime Accident Investigation Branch in the UK. By providing an analysis of reported casualties and incidents, it highlights current challenges in maritime safety. For each casualty and incident, the study reviews the underlying causal factors. These causal factors are then coded according to the functional sections of the ISM Code, covering various aspects of safety management. To investigate human and organizational factors involved in the casualties and incidents, the human factor analysis and classification system (HFACS) is applied to code the same data. Finally, the relative seriousness of casualties and incidents is considered to discuss the findings from ISM Code and HFACS reviews. The study found that the main challenges pertain to the development of plans for shipboard operations, local shipboard management, and the ability of the company to verify when such practices deviate from best practices or required standards.
What makes a joint venture: Micro‐evidence from Sino‐Italian contracts
Authors: Gattai Valeria , Natale Piergiovanna 
Published: August 2013

AbstractThis paper provides new contract‐level evidence on control rights allocation in order to define what makes a joint venture. Property rights theory of the firm identifies circumstances under which joint control alleviates investment distortions due to contract incompleteness. We compare predictions of the theoretical literature with actual governance structures of Sino‐Italian joint ventures, as reported in a questionnaire submitted to the entire population of Italian enterprises operating in China. With an exceptional response rate of 60%, our evidence confirms most of the theoretical predictions and helps select among competing approaches to model joint ventures.
Decompression mineral microtextures in granulites of the Irkut block (Sharyzhalgai uplift of the Siberian Platform)
Authors: Sukhorukov V.P. 
Published: August 2013

Abstract
This paper presents mineral reactions in metapelites and estimations of PT-conditions of metamorphism for paragranulites of the Irkut block of the Sharyzhalgay uplift (Siberian Platform). The geothermometeric data based on exchange reactions, the contents of Na in cordierite and Ti in zircon indicate that the peak temperature of metamorphism reached ca. 800 °C at 6–7 kbar. The observed mineral reactions suggest that the pressure decreased to ca. 3 kbar at a retrograde stage of metamorphism.
Conditions of the accumulation of organic matter and metals in the bottom sediments of the Chukchi Sea

Published: August 2013

Abstract
The chemical composition of bottom sediments in the Chukchi and, partly, East Siberian Seas was studied. In the south and west of the Chukchi Sea, a zone has been detected with the accumulation of sediments rich in organic carbon, an increased background content and anomalies of sulfophile metals (Mo, Zn, Hg, Ag, Au), iron-group metals (V, Ni, Co), and some PGE (Ru, Pt). This zone is confined to the neotectonic active system of rift troughs extending from the Bering Strait and eastern Chukchi Peninsula to the continental slope, where it is bounded by the Cenozoic Charlie rift basin of the Canadian hollow. The geochemical features of the carbon-enriched sediments evidence that they formed under oxygen-deficient conditions and, sometimes, in suboxic and anoxic environments near endogenic water and gas sources. The high carbon and metal contents suggest that the very fine-grained sediments in the rift troughs of the Chukchi Sea are a possible analog of some types of ancient highly carbonaceous sediments belonging to black shales.

AbstractAttachment formation is the most pivotal factor for humans and animals in the growth and development of social relationships. However, the developmental processes of attachment formation mediated by sensory-motor, emotional and cognitive integration remain obscure. Here we developed an animal model to understand the types of social interactions that lead to peer-social attachment formation. We found that the social interaction in a sensitive period was essential to stabilise or overwrite the initially imprinted peer affiliation state and that synchronised behaviour with others based on common motivations could be a driver of peer social attachment formation. Furthermore, feeding experience with supplementation of ubiquinol conferred peer social attachment formation even after the sensitive period. Surprisingly, the experience of feeding beyond the cage window was also effective to reduce the required amount ubiquinol, suggesting that peri-personal space modulation may affect socio-emotional cognition and there by lead to attachment formation.

AimsTo evaluate how recommendations of European guidelines regarding pharmacological and non‐pharmacological treatments for heart failure (HF) are adopted in clinical practice.Methods and resultsThe ESC‐HF Long‐Term Registry is a prospective, observational study conducted in 211 Cardiology Centres of 21 European and Mediterranean countries, members of the European Society of Cardiology (ESC). From May 2011 to April 2013, a total of 12 440 patients were enrolled, 40.5% with acute HF and 59.5% with chronic HF. Intravenous treatments for acute HF were heterogeneously administered, irrespective of guideline recommendations. In chronic HF, with reduced EF, renin–angiotensin system (RAS) blockers, beta‐blockers, and mineralocorticoid antagonists (MRAs) were used in 92.2, 92.7, and 67.0% of patients, respectively. When reasons for non‐adherence were considered, the real rate of undertreatment accounted for 3.2, 2.3, and 5.4% of the cases, respectively. About 30% of patients received the target dosage of these drugs, but a documented reason for not achieving the target dosage was reported in almost two‐thirds of them. The more relevant reasons for non‐implantation of a device, when clinically indicated, were related to doctor uncertainties on the indication, patient refusal, or logistical/cost issues.ConclusionThis pan‐European registry shows that, while in patients with acute HF, a large heterogeneity of treatments exists, drug treatment of chronic HF can be considered largely adherent to recommendations of current guidelines, when the reasons for non‐adherence are taken into account. Observations regarding the real possibility to adhere fully to current guidelines in daily clinical practice should be seriously considered when clinical practice guidelines have to be written.

Abstract
Liu, Y., Saitoh, S-I., Radiarta, I. N., Isada, T., Hirawake, T., Mizuta, H., and Yasui, H. 2013. Improvement of an aquaculture site-selection model for Japanese kelp (Saccharinajaponica) in southern Hokkaido, Japan: an application for the impacts of climate events. – ICES Journal of Marine Science, 70: . Japanese kelp (Saccharinajaponica) is one of the most valuable cultured and harvested kelp species in Japan. In this study, we added a physical parameter, sea surface nitrate (SSN) estimated from satellite remote sensing data, to develop a suitable aquaculture site-selection model (SASSM) for hanging cultures of Japanese kelp in southern Hokkaido, Japan. The local algorithm to estimate SSN was developed using satellite measurements of sea surface temperature and chlorophyll-a. We found a high correlation between satellite- and ship-measured data (r2 = 0.87, RMSE = 1.39). Multi-criteria evaluation was adapted to the SASSM to rank sites on a scale of 1 (least suitable) to 8 (most suitable). We found that 64.4% of the areas were suitable (score above 7). Minamikayabe was identified as the most suitable area, and Funka Bay also contained potential aquaculture sites. In addition, we examined the impact of El Niño/La Niña–Southern Oscillation (ENSO) events on Japanese kelp aquaculture and site suitability from 2003–2010. During El Niño events, the number of suitable areas (scores 7 and 8) decreased significantly, indicating that climatic conditions should be considered for future development of marine aquaculture.

AbstractZwolinski, J. P., and Demer, D. A. 2013. Measurements of natural mortality for Pacific sardine (Sardinops sagax). – ICES Journal of Marine Science, 70: . The northern stock of Pacific sardine (Sardinops sagax) in the California Current Ecosystem is periodically assessed to provide harvest guidelines for the United States and Canadian fisheries. The assessment model incorporates the estimates of abundance from acoustic-trawl method (ATM) and other surveys and many parameters including a constant value for the instantaneous natural mortality coefficient (M). Here, the ATM-estimated length-structured sardine abundances for 2006–2011 are combined to directly estimate M. The stock was dominated by the 2003, 2004, and 2005 year classes (2003–2005 cohort) from 2006 to 2010 and by the 2009 and 2010 year classes in 2011. Insignificant recruitments during 2006–2010 allowed the 2003–2005 cohort to be tracked and M to be estimated. The bootstrap distributions of estimated M encompass the assessment-assumed value of 0.4−year. The measurements suggest that M is high for a new cohort, declines during mid-life, then increases as the fish approach their longevity. The mean M for the entire period, 0.52, is 30% higher than the one currently assumed for the assessment, reflecting the steeper decline in the ATM-estimated biomass versus that in the assessment model.
