Multiscale modeling of heterogeneous magnetic materials
Authors: Bottauscio Oriano , Chiampi Mario , Manzin Alessandra 
Published: September 2013

ABSTRACTThis paper analyzes and discusses some computational methods for the simulation of the electric and magnetic behavior versus frequency of heterogeneous soft magnetic materials (such as soft magnetic composites, soft ferrites, and polymer composites). All these media are characterized by a granular structure, with magnetic grains separated by high resistivity layers, so that the study involves phenomena occurring at both macroscopic (sample size) and microscopic scale (grain size). The main purpose of the analysis is the prediction of the effective magnetic and electric properties, and of the relative energy losses starting from the known properties of the constituents, as well as the extrapolation of the constituent parameters from the measured global properties of the heterogeneous medium (inverse problem). The adopted computational methodologies include both analytical mixing rules and numerical approaches on the basis of homogenization and multiscale methods. The paper reports some examples illustrating advantages and drawbacks of these techniques, giving also an outline of nonlinear media homogenization. Copyright © 2013 John Wiley & Sons, Ltd.
Portable NIR‐AOTF spectroscopy combined with winery FTIR spectroscopy for an easy, rapid, in‐field monitoring of Sangiovese grape quality
Authors: Barnaba Federico Emanuele , Bellincontro Andrea , Mencarelli Fabio 
Published: September 2013

AbstractBACKGROUNDA near infrared acousto‐optically tunable filter (NIR‐AOTF) spectrophotometer was tested for three seasons on four different vineyards with the aim of monitoring the ripening evolution of the Italian red wine grape variety Sangiovese. Predictive models for the estimation of several enological parameters were carried out applying the partial least squares chemometric approach. Reference analysis was conducted using Fourier transform infrared spectroscopy (FTIR). Spectral detections were obtained working on whole grape berries. A global set of 96 samples (n = 76 in 2009, and n = 20 in 2010) each one represented by 100 intact grape berries was tested. Finally, in 2011, an external validation on an independent data set of 25 samples (50 grape berries per set) was carried out.RESULTSCoupling the two spectroscopic applications, the following enological parameters were tested: °Brix, °Babo, total sugars (g L−1), glucose (g L−1), fructose (g L−1), density (g mL−1), titratable acidity (g L−1), tartaric acid (g L−1), pH, malic acid (g L−1), gluconic acid (g L−1), assumable nitrogen (mg L−1), anthocyanins (mg L−1), and total phenols (mg L−1). NIR‐AOTF spectroscopy was able to predict with a high correlation versus the measured data: °Brix, °Babo, total sugars, glucose, fructose and density. The coefficient of determination (R2) and the standard error in prediction were: 0.93 and 0.73 for °Brix; 0.93 and 0.62 for °Babo; 0.94 and 7.39 g L−1 for total sugars; 0.93 and 5.39 g L−1 for glucose; 0.92 and 5.07 g L−1 for fructose; and 0.91 and 0.004 g mL−1 for density, respectively. Significant correlations were found in prediction for tartaric acid and pH value. Promising validation results were recorded for anthocyanins and total phenols, even though predictive models were affected by the method of sample preparation in compound extraction.CONCLUSIONSThis study shows how NIR‐AOTF spectroscopy can be used in viticulture to investigate, directly in‐field, the most significant markers of ripening evolution and of Sangiovese grape quality definition. The use of the vinery FTIR spectroscopy provided the reduction of the time required by reference analysis, with the big advantage of obtaining many different parameters in just a few seconds and allowing easier calibration of the NIR spectrometer. © 2013 Society of Chemical Industry
Thermal management of edge‐lit wide color gamut backlight for LCD using red laser diodes and cyan LEDs
Authors: Nagase Akihiro , Niikura Eiji , Shinozaki Masaru , Nagayasu Tetsuya , Kondo Taiji , Ohashi Gosuke 
Published: September 2013

AbstractThe color gamut is one of the critical parameters that dictate the image quality of displays. The liquid crystal displays using white color light‐emitting diodes (LEDs) as the backlight, though having been widely employed recently, are not very satisfactory in terms of their color gamut because of the broad spectrum inherent to white LEDs. This prompted the authors to develop improved liquid crystal displays using an edge‐lit wide color gamut backlight that used red laser diodes and cyan LEDs. Generating laser beams with high color purity, the laser diodes are light sources with a significant effect on expanding the color gamut. However, laser diodes, red ones in particular, have unfavorable thermal characteristics. To cope with this shortcoming, the authors clearly defined the restrictive criteria for laying out two kinds of light source on the edge‐lit backlight and made a prototype 55‐type laser backlight for performance evaluation.
Micellization of St/MMA Gradient Copolymers: A General Picture of Structural Transitions in Gradient Copolymer Micelles
Authors: Zheng Chao , Huang Haiying , He Tianbai 
Published: September 2013

In this work, a gradient copolymer of styrene (St) and methyl methacrylate (MMA) is synthesized via reversible addition–fragmentation chain transfer living radical polymerization and its micellization behaviors in an acetone and water mixture are investigated by transmission electron microscopy, light scattering, and NMR spectroscopy. Three different kinds of transitions were found to coexist in a single system for the first time: a unimers to micelles transition, a star‐like micelles to crew‐cut micelles transition resulting from the shrinkage of micelles, and morphological transitions from spherical micelles to cylindrical micelles to vesicles. Our findings provide a general picture of structural transitions and relaxation processes in gradient copolymer micelles, which can lead to the development of novel materials and applications based on gradient copolymers.

Efficacy of insecticide residues on adult Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) mortality and injury in apple and peach orchards
Authors: Leskey Tracy C. , Short Brent D. , Lee Doo‐Hyung 
Published: September 2013

AbstractBACKGROUNDThe primary threat from Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) originates from populations continuously dispersing from and among wild and cultivated hosts, so many individuals may not be directly sprayed with insecticides. Limited information exists regarding field‐based residual activity of insecticides for management of H. halys in tree fruit. Thus, we conducted field‐based bioassays in apple and peach orchards to evaluate residual activity of insecticides commonly applied against H. halys. Adults used in these trials were collected from wild and cultivated hosts less than one week prior to testing to more accurately reflect the susceptibility of wild H. halys populations in the field throughout the season.RESULTSSignificantly higher mortality rates of Halyomorpha halys were observed early in the growing season, when overwintered adults were prevalent, compared with populations present later in the growing season that included new generation adults. Significantly higher mortality was recorded for adults exposed to fresh insecticide applications compared with three‐ and seven‐day old residues. Typically, the addition of an adjuvant did not enhance efficacy or residual activity of insecticides. Significantly fewer injury sites were recorded on apples treated with dinotefuran and fenpropathrin compared with the untreated apples for all residue ages.CONCLUSIONSOverwintered Halyomorpha halys populations are easier to kill with insecticide applications than the first and second generation which are present in the field during the mid‐ to late‐season. Residual activity of nearly all insecticides decreased significantly three days after application and adjuvants generally did not increase residual activity. These factors should be considered in developing season‐long programs for management of this invasive species in tree fruit. © 2013 Society of Chemical Industry
Sampled‐data control of networked nonlinear systems with variable delays and drops
Authors: Liu Xi , Marquez Horacio J. , Kumar K.D. , Lin Y. 
Published: September 2013

SUMMARYThis paper investigates the stabilization problem of the nonlinear networked control systems (NCSs) with drops and variable delays. The NCS is modeled as a sampled‐data system. For such a sampled‐data NCS, the stability properties are studied for delay that can be both shorter and longer than one sampling period, respectively. The exponential stability conditions are derived in terms of the parameters of the plant and time delay. On the other hand, a model‐based control scheme based on an approximate discrete‐time model of the plant is presented to guarantee the stability of the closed‐loop system subject to variable time delays and packet losses. The performance of the proposed control schemes are examined through numerical simulations of an automated rendezvous and docking of spacecraft system. Moreover, the simulations show that by employing the model‐based controller, a higher closed‐loop control performance can be achieved. Copyright © 2013 John Wiley & Sons, Ltd.
Character‐based symmetric searchable encryption and its implementation and experiment on mobile devices
Authors: Suga Takanori , Nishide Takashi , Sakurai Kouichi 
Published: September 2013

AbstractSearchable encryption allows us to perform a keyword search over encrypted data. However, we cannot efficiently perform some complex search (e.g., a wildcard search) with traditional searchable encryption schemes because they can deal with only equality matches. Our symmetric searchable encryption can deal with partial matches. This allows us to efficiently perform a wildcard search, partial match search, and so on. We also examine the feasibility of our scheme by experiments on a smartphone and tablet, and confirm our scheme can be used in these environments. Availability on portable devices will offer high convenience. Copyright © 2013 John Wiley & Sons, Ltd.

Published: September 2013

AbstractNumerous groups of health professionals have undertaken the task of defining core competencies for their profession. The goal of establishing core competencies is to have a defined standard for such professional needs as practice guidelines, training curricula, certification, continuing competency and re‐entry to practice. In 2006, the Canadian Association of Genetic Counsellors (CAGC) recognized the need for uniform practice standards for the profession in Canada, given the rapid progress of genetic knowledge and technologies, the expanding practice of genetic counsellors and the increasing demand for services. We report here the process by which the CAGC Practice Based Competencies were developed and then validated via two survey cycles, the first within the CAGC membership, and the second with feedback from external stakeholders. These competencies were formally approved in 2012 and describe the integrated skills, attitudes and judgment that genetic counsellors in Canada require in order to perform the services and duties that fall within the practice of the profession responsibly, safely, effectively and ethically.
Stress‐Temperature Effects on Transitions in PEO17PPO60PEO17 Triblock Copolymer Micellar Solutions

Published: September 2013

AbstractIn this work, the shear thickening behavior of micellar solutions of the PEO17PPO60PEO17 triblock copolymer as a function of applied shear stress and temperature is reported. Both, dynamic light scattering and rheological measurements, confirm micellar growth upon increasing temperature and/or applied stress, after an induction time. A synergetic effect of temperature and stress on the intensity of shear thickening (up to three‐order of magnitude) is demonstrated by a combination of T‐jump experiments and application of shear stress. The effect of temperature on the induction and saturation times, detected during the viscosity rise after applying both, a T‐jump and shear stress, is also examined.
Time well spent: The duration of foster care and early adult labor market, educational, and health outcomes
Authors: Fallesen Peter 
Published: September 2013

AbstractIndividuals who spent time in foster care as children fare on average worse than non‐placed peers in early adult life. Recent research on the effect of foster care placement on early adult life outcomes provides mixed evidence. Some studies suggest negative effects of foster care placement on early adult outcomes, others find null effects. This study shows that differences in the average duration of foster care stays explain parts of these discordant findings and then test how foster care duration shapes later life outcomes using administrative data on 7220 children. The children experienced different average durations of foster care because of differences in exposure to a reform. Later born cohorts spent on average 3 months longer in foster care than earlier born cohorts. Isolating exogenous variation in duration of foster care, the study finds positive effects of increased duration of foster care on income and labor market participation.
Turbophoresis attenuation in a turbulent channel flow with polymer additives
Authors: Nowbahar Arash , Sardina Gaetano , Picano Francesco , Brandt Luca 
Published: September 2013

AbstractTurbophoresis occurs in wall-bounded turbulent flows where it induces a preferential accumulation of inertial particles towards the wall and is related to the spatial gradients of the turbulent velocity fluctuations. In this work, we address the effects of drag-reducing polymer additives on turbophoresis in a channel flow. The analysis is based on data from a direct numerical simulation of the turbulent flow of a viscoelastic fluid modelled with the FENE-P closure and laden with particles of different inertia. We show that polymer additives decrease the particle preferential wall accumulation and demonstrate with an analytical model that the turbophoretic drift is reduced because the wall-normal variation of the wall-normal fluid velocity fluctuations decreases. As this is a typical feature of drag reduction in turbulent flows, an attenuation of turbophoresis and a corresponding increase in the particle streamwise flux are expected to be observed in all of these flows, e.g. fibre or bubble suspensions and magnetohydrodynamics.
AN EXAMPLE CONCERNING BOUNDED LINEAR REGULARITY OF SUBSPACES IN HILBERT SPACE
Authors: REICH SIMEON , ZASLAVSKI ALEXANDER J. 
Published: September 2013

AbstractWe study bounded linear regularity of finite sets of closed subspaces in a Hilbert space. In particular, we construct for each natural number $n\geq 3$ a set of $n$ closed subspaces of ${\ell }^{2} $ which has the bounded linear regularity property, while the bounded linear regularity property does not hold for each one of its nonempty, proper nonsingleton subsets. We also establish a related theorem regarding the bounded regularity property in metric spaces.

Divine maximal beauty: a reply to Jon Robson
Authors: ROBSON MARK IAN THOMAS 
Published: September 2013

AbstractIn this article I reply to Jon Robson's objections to my argument that God does not contain any possible worlds. I had argued that ugly possible worlds clearly compromise God's beauty. Robson argues that I failed to show that possible worlds can be subject to aesthetic evaluation, and that even if they were it could be the case that ugliness might contribute to God's overall beauty. In reply I try to show that possible worlds are aesthetically evaluable by arguing that possible worlds are maximally rich representations of possible events. I further argue that nothing in God's being can be aesthetically non-evaluable since God must be maximal beauty – a beauteous maximality which needs no ugliness. Finally I show in what sense Christ's heavenly scars can be beautiful.
From Two Camps to Three Worlds: The Party Worldview in PRC Textbooks (1949–1966)
Authors: Yu Miin-ling 
Published: September 2013

AbstractThe worldview as reflected in the textbooks of the People's Republic of China during 1949–1966 centred on Party-led nationalism, anti-imperialism and anti-colonialism. This article emphasizes both the continuities and changes in nationalist ideology during the Republican and Maoist periods. First, textbooks in Maoist China presented the imperialist powers as shifting away from Britain, Russia and Japan under the KMT government and towards the United States (since 1949) and the Soviet Union (since the 1960s), and emphasized class struggle. Second, the CCP had far greater control over the production of textbooks than the KMT. In this sense, the CCP truly carried out “partified” (danghua) education, a goal shared by the KMT which it never had the ability to achieve. In addition, “the language of Cultural Revolution” appeared with the outbreak of the Korean War. In other words, the education that cultivated revolutionary successors began in the early 1950s.
The interaction between humanitarian non-governmental organisations and extractive industries: a perspective from Médecins Sans Frontières
Authors: Calain Philippe 
Published: September 2013

AbstractThis opinion note explores some aspects of the relationship between humanitarian non-governmental organisations (NGOs) and extractive industries. Médecins sans Frontières (Doctors without Borders, MSF) has endorsed a policy of non-engagement with the corporate sector of the extractive industries, particularly when it comes to financial donations. This is coherent with MSF being first and foremost a medical organisation, and one that adheres to the humanitarian principles of independence and neutrality. For humanitarian actors, the prospect of future environmental disasters and environmental conflicts calls for the anticipation of novel encounters, not only with environmental organisations but also with the extractive sector. Unlike environmental organisations, extractive industries are prone to generating or perpetuating different forms of violence, often putting extractive companies on a par with the parties to armed conflicts. In situations where a dialogue with extractive companies would be needed to optimise care and access to victims, humanitarian organisations should carefully weigh pragmatic considerations against the risk of being co-opted as medical providers of mitigation measures.
Genomic properties of Marine Group A bacteria indicate a role in the marine sulfur cycle

Published: September 2013

Abstract
Marine Group A (MGA) is a deeply branching and uncultivated phylum of bacteria. Although their functional roles remain elusive, MGA subgroups are particularly abundant and diverse in oxygen minimum zones and permanent or seasonally stratified anoxic basins, suggesting metabolic adaptation to oxygen-deficiency. Here, we expand a previous survey of MGA diversity in O2-deficient waters of the Northeast subarctic Pacific Ocean (NESAP) to include Saanich Inlet (SI), an anoxic fjord with seasonal O2 gradients and periodic sulfide accumulation. Phylogenetic analysis of small subunit ribosomal RNA (16S rRNA) gene clone libraries recovered five previously described MGA subgroups and defined three novel subgroups (SHBH1141, SHBH391, and SHAN400) in SI. To discern the functional properties of MGA residing along gradients of O2 in the NESAP and SI, we identified and sequenced to completion 14 fosmids harboring MGA-associated 16S RNA genes from a collection of 46 fosmid libraries sourced from NESAP and SI waters. Comparative analysis of these fosmids, in addition to four publicly available MGA-associated large-insert DNA fragments from Hawaii Ocean Time-series and Monterey Bay, revealed widespread genomic differentiation proximal to the ribosomal RNA operon that did not consistently reflect subgroup partitioning patterns observed in 16S rRNA gene clone libraries. Predicted protein-coding genes associated with adaptation to O2-deficiency and sulfur-based energy metabolism were detected on multiple fosmids, including polysulfide reductase (psrABC), implicated in dissimilatory polysulfide reduction to hydrogen sulfide and dissimilatory sulfur oxidation. These results posit a potential role for specific MGA subgroups in the marine sulfur cycle.
