Tuning of near‐ and far‐field properties of all‐dielectric dimer nanoantennas via ultrafast electron‐hole plasma photoexcitation
Authors: Baranov Denis G. , Makarov Sergey V. , Krasnok Alexander E. , Belov Pavel A. , Alù Andrea 
Published: November 2016

AbstractAll‐optical ultrafast signal modulation and routing by low‐loss nanodevices is a crucial step towards an ultracompact optical chip with high performance. Here, we propose a specifically designed silicon dimer nanoantenna, which is tunable via photoexcitation of dense electron‐hole plasma with ultrafast relaxation rate. On the basis of this concept, we demonstrate the effect of beam steering by up to 20 degrees through simple variation of the intensity of incident light. The effect, which is suitable for ultrafast light routing in an optical chip, is demonstrated both in the visible and near‐IR spectral regions for silicon‐ and germanium‐based nanoantennas. We also reveal the effect of electron‐hole plasma photoexcitation on the local density of states (LDOS) in the dimer gap and find that the orientation averaged LDOS can be altered by 50%, whereas modification of the projected LDOS can be even more dramatic, almost five‐fold for transverse dipole orientation. Moreover, our analytical model sheds light on the transient dynamics of the studied nonlinear nanoantennas, yielding all temporal characteristics of the suggested ultrafast nanodevice. The proposed concept paves the way to the creation of low‐loss, ultrafast, and compact devices for optical signal modulation and routing.

Published: November 2016

Performances of a newly developed microprocess in producing size‐controlled nanoemulsions in the lower nanometer range are assessed. The microprocess comprises an elongational‐flow micromixer with a bore size of either 150, 250, or 500 μm. By inducing a reciprocating flow through the restriction of the micromixer, methyl methacrylate (MMA)‐based nanoemulsions with controlled sizes in the range 50–300 nm are successfully prepared at low pressures (ca. 2.5 bars) in laminar to intermediate hydrodynamic flow regimes. Effect of process parameters (flow rate through the restriction, number of cycles), micromixer parameters (angle, bore size), and finally composition parameters (weight content of MMA and surfactant, dispersed to continuous phase viscosity ratio) on nanodroplet size and size distribution is thoroughly studied. A unique empirical correlation is extracted from the experimental results and is found to fairly well model the variations of the nanodroplet size with aforementioned parameters.

Are Parental Welfare Work Requirements Good for Disadvantaged Children? Evidence From Age‐of‐Youngest‐Child Exemptions
Authors: Herbst Chris M. 
Published: November 2016

AbstractThis paper assesses the impact of welfare reform's parental work requirements on low‐income children's cognitive and social‐emotional development. The identification strategy exploits an important feature of the work requirement rules—namely, age‐of‐youngest‐child exemptions—as a source of quasi‐experimental variation in first‐year maternal employment. The 1996 welfare reform law empowered states to exempt adult recipients from the work requirements until the youngest child reaches a certain age. This led to substantial variation in the amount of time that mothers can remain home with a newborn child. I use this variation to estimate the impact of work‐requirement‐induced increases in maternal employment. Using a sample of infants from the Birth cohort of the Early Childhood Longitudinal Study, the reduced form and instrumental variables estimates reveal sizable negative effects of maternal employment. An auxiliary analysis of mechanisms finds that working mothers experience an increase in depressive symptoms, and are less likely to breastfeed and read to their children. In addition, such children are exposed to nonparental child care arrangements at a younger age, and they spend more time in these settings throughout the first year of life.

AbstractHydrodynamic and optical methods were applied to study conformational and physical properties of hyperbranched pyridylphenylene polymers in dilute solutions. The samples were synthesized using Diels–Alder polycyclocondensation. It was demonstrated that hydrodynamic properties of the studied macromolecules were typical for compact non‐percolated spheres. Optical and electro‐optical methods revealed information regarding the shape and asymmetry of the macromolecules (p ≈ 1.4). The contributions of optical shape effect to the observed flow birefringence of polypyridylphenylene solutions and intrinsic anisotropy of polarizability were evaluated and analysed. It was shown that varying the polymer composition (i.e. the degree of branching) caused considerable changes in the anisotropy of optical polarizability of the polymers. Dramatic difference of the electro‐optical properties in non‐polar (toluene) and polar (tetrachloroethane) solvents was found; this difference was related to the orientational correlation of polar solvent molecules with respect to the macromolecules. Dynamic properties were studied by non‐equilibrium electric birefringence which had a reasonable agreement with the dimensions estimated from hydrodynamic data. © 2016 Society of Chemical Industry
Regulation of mRNA turnover in cystic fibrosis lung disease
Authors: Biswas Roopa , Kumar Parameet , Pollard Harvey B. 
Published: November 2016

Cystic fibrosis (CF) is an autosomal recessive disease due to mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, F508del‐CFTR
being the most frequent mutation. The CF lung is characterized by a hyperinflammatory phenotype and is regulated by multiple factors that coordinate its pathophysiology. In CF the expression of CFTR as well as proinflammatory genes are regulated at the level of messenger RNA (mRNA) stability, which subsequently affect translation. These mechanisms are mediated by inflammatory RNA‐binding proteins as well as small endogenous noncoding microRNAs, in coordination with cellular signaling pathways. These regulatory factors exhibit altered expression and function in vivo in the CF lung, and play a key role in the pathophysiology of CF lung disease. In this review, we have described the role of mRNA stability and associated regulatory mechanisms in CF lung disease.

The human physiological impact of global deoxygenation
Authors: Martin Daniel , McKenna Helen , Livina Valerie 
Published: November 2016

Abstract
There has been a clear decline in the volume of oxygen in Earth’s atmosphere over the past 20 years. Although the magnitude of this decrease appears small compared to the amount of oxygen in the atmosphere, it is difficult to predict how this process may evolve, due to the brevity of the collected records. A recently proposed model predicts a non-linear decay, which would result in an increasingly rapid fall-off in atmospheric oxygen concentration, with potentially devastating consequences for human health. We discuss the impact that global deoxygenation, over hundreds of generations, might have on human physiology. Exploring the changes between different native high-altitude populations provides a paradigm of how humans might tolerate worsening hypoxia over time. Using this model of atmospheric change, we predict that humans may continue to survive in an unprotected atmosphere for ~3600 years. Accordingly, without dramatic changes to the way in which we interact with our planet, humans may lose their dominance on Earth during the next few millennia.
Moving Beyond Salmon Bias: Mexican Return Migration and Health Selection

Published: November 2016

Abstract
Despite having lower levels of education and limited access to health care services, Mexican immigrants report better health outcomes than U.S.-born individuals. Research suggests that the Mexican health advantage may be partially attributable to selective return migration among less healthy migrants—often referred to as “salmon bias.” Our study takes advantage of a rare opportunity to observe the health status of Mexican-origin males as they cross the Mexican border. To assess whether unhealthy migrants are disproportionately represented among those who return, we use data from two California-based studies: the California Health Interview Survey; and the Migrante Study, a survey that samples Mexican migrants entering and leaving the United States through Tijuana. We pool these data sources to look for evidence of health-related return migration. Results provide mixed support for salmon bias. Although migrants who report health limitations and frequent stress are more likely to return, we find little evidence that chronic conditions and self-reported health are associated with higher probabilities of return. Results also provide some indication that limited health care access increases the likelihood of return among the least healthy. This study provides new theoretical considerations of return migration and further elucidates the relationship between health and migration decisions.

AbstractPercutaneous release (PR) of the A1 pulley is a quick, safe, and minimally invasive procedure for treating trigger fingers. The purpose of this study is to identify if PR with additional steroid injections can shorten the recovery to reach unlimited range of motion. Between January 2013 and December 2013, we included 432 trigger fingers with actively correctable triggering or severer symptoms without previous surgical release or steroid injections from two hand clinic offices (A and B). The same experienced surgeon performed PR at the office. Patients from Clinic A received PR with steroid injections and those from Clinic B received PR without steroid injections. Patients returned for follow‐up 1 week, 6 weeks, and 12 weeks after the procedure. Between the steroid group and the nonsteroid group, there is no significant difference in the mean time for patients to return to normal work and the rate of residual extensor lag. Middle fingers showed a 5.09‐fold chance of having a residual extensor lag over that of the other fingers. High grade trigger fingers recovered more slowly than low grade ones. The success rate of a 12‐week follow‐up was 98.4%. There was no significant difference between the steroid group (97.5%) and the nonsteroid group (99.1%). PR can treat trigger fingers effectively, but additional steroid injection does not provide more benefit. Some fingers showed temporary extensor lag, especially in middle fingers and high grade trigger fingers, but 85% of those will eventually reach full recovery after self‐rehabilitation without another surgical release.
Social Factors Associated With Psychological Distress and Health Problems Among Elderly Members of a Disaster-Affected Population: Subgroup Analysis of a 1-Year Post-disaster Survey in Ishinomaki Area, Japan
Authors: Inoue Mariko , Yamaoka Kazue 
Published: November 2016

AbstractObjectiveWe aimed to investigate the influence of social factors, especially social support, on psychological distress and the prevalence of health problems (HPs) among victims living in their homes 14 to 21 months after the Great East Japan Earthquake and tsunami.MethodsA subgroup analysis was performed for elderly participants of a cross-sectional household survey in Ishinomaki area, Japan. The prevalence of psychological HPs was assessed by using a psychological distress questionnaire (K6) and by recording the number of subjective HPs. Perceived social support was assessed in 3 dimensions: informational, emotional, and instrumental support. Univariate and multivariate logistic regression models were used to examine the association between social factors and psychological health.ResultsAn elderly subgroup with 879 participants was used for analyses. Psychological distress (K6 score≥9) was observed in 6.8% of the participants aged 65 to 74 years and in 8.0% of those aged ≥75 years. Receiving a long-term care service was associated with having HPs, and discontinuation of attendance at a hospital as an outpatient was associated with psychological distress. Receiving emotional support was associated with lower psychological distress and not having HPs.ConclusionsEmotional support was found to be an important factor for promoting health among elderly disaster victims.

Sum-of-squares approach to feedback control of laminar wake flows
Authors: Lasagna Davide , Huang Deqing , Tutty Owen R. , Chernyshenko Sergei 
Published: November 2016

In this paper a novel nonlinear feedback control design methodology for incompressible fluid flows aiming at the optimisation of long-time averages of flow quantities is presented. It applies to reduced-order finite-dimensional models of fluid flows, expressed as a set of first-order nonlinear ordinary differential equations with the right-hand side being a polynomial function in the state variables and in the controls. The key idea, first discussed in Chernyshenkoet al.(Phil. Trans. R. Soc. Lond. A, vol. 372, 2014, 20130350), is that the difficulties of treating and optimising long-time averages of a cost are relaxed by using the upper/lower bounds of such averages as the objective function. In this setting, control design reduces to finding a feedback controller that optimises the bound, subject to a polynomial inequality constraint involving the cost function, the nonlinear system, the controller itself and a tunable polynomial function. A numerically tractable and efficient approach to the solution of such optimisation problems, based on sum-of-squares techniques and semidefinite programming, is proposed. To showcase the methodology, the mitigation of the fluctuation kinetic energy in the unsteady wake behind a circular cylinder in the laminar regime at$Re=100$, via controlled angular motions of the surface, is numerically investigated. A compact reduced-order model that resolves the long-term behaviour of the fluid flow and the effects of actuation, is first derived using proper orthogonal decomposition and Galerkin projection. In a full-information setting, feedback controllers are then designed to reduce the long-time average of the resolved kinetic energy associated with the limit cycle. These controllers are then implemented in direct numerical simulations of the actuated flow. Control performance, total energy efficiency and the physical control mechanisms identified are analysed in detail. Key elements of the methodology, implications and future work are finally discussed.

AbstractWe evaluated the association between dietary estimates of fatty acid (FA) consumption and type 2 diabetes (T2D) risk in the French E3N (Etude Epidémiologique auprès des femmes de la Mutuelle Générale de l’Education Nationale) cohort. In total, 71 334 women without diabetes at baseline were followed up from 1993 to 2011. Diabetes was identified using questionnaires and drug-reimbursement claims, and incident cases were validated. FA consumption in 1993 was estimated from a validated dietary questionnaire. Cox regression estimated hazard ratios (HR) and 95 % CI of diabetes risk, comparing the upper tertile group with the lowest. High n-3 PUFA consumption was associated with T2D even after adjustment for confounders, including other FA and BMI (HR 1·26; 95 % CI 1·13, 1·41; upper tertile compared with lowest). Upon stratification by overweight (BMI≥25 kg/m2)/non-overweight, a positive association between total PUFA consumption and T2D was observed, but it was restricted to non-overweight women (HR 1·22; 95 % CI 1·05, 1·42), whereas n-3 PUFA consumption was associated with increased T2D risk in both BMI strata (BMI<25 kg/m2: HR 1·19; 95 % CI 1·01, 1·40 and BMI≥25 kg/m2: HR 1·38; 95 % CI 1·20, 1·59). Within the n-3 PUFA, high DPA (HR 1·41; 95 % CI 1·23, 1·63) and α-linolenic acid (ALA) intakes were associated with increased T2D risk, but the effects of ALA were restricted to overweight women (HR 1·17; 95 % CI 1·01, 1·36). Within the n-6 PUFA, only arachidonic acid (AA) intake was associated with T2D risk (HR 1·49; 95 % CI 1·33, 1·66). The associations with DPA and AA persisted even after adjustment of their principal source in this cohort, the consumption of meat. The effects of PUFA are heterogeneous within the FA group. Intake of DPA and AA may contribute to T2D development.
Description and experimental transmission of Tetracapsuloides vermiformis n. sp. (Cnidaria: Myxozoa) and guidelines for describing malacosporean species including reinstatement of Buddenbrockia bryozoides n. comb. (syn. Tetracapsula bryozoides)

Published: November 2016

SUMMARYThis paper provides the first detailed description of a Tetracapsuloides species, Tetracapsuloides vermiformis n. sp., with vermiform stages in the bryozoan host, Fredericella sultana, and its experimental transmission from F. sultana to Cyprinus carpio. The suitability of morphological, biological and 18S rDNA sequence data for discrimination between malacosporean species is reviewed and recommendations are given for future descriptions. Presently, malacosporean species cannot be differentiated morphologically due to their cryptic nature and the lack of differential characters of spores and spore-forming stages in both hosts. We examined biological, morphological and molecular characters for the present description and for revising malacosporean taxonomy in general. As a result, Buddenbrockia plumatellae was split into two species, with its sac-like stages being ascribed to Buddenbrockia bryozoides n. comb. In addition to ribosomal DNA sequences multiple biological features rather than morphological characters are considered essential tools to improve malacosporean taxonomy in the future according to our analysis of the limited traits presently available.
Incentives facing UK-listed companies to comply with the risk reporting provisions of the UK Corporate Governance Code
Authors: Klumpes P. , Ledlie C. , Fahey F. , Kakar G. , Styles S. 
Published: November 2016

AbstractRecent changes made to the UK Corporate Governance Code require UK firms to report new or enhanced narrative information concerning their principal risks, their risk management processes and their future viability. This paper analyses whether the level and nature of voluntary compliance with these new requirements is consistent with alternative economic and political visibility incentives. We analyse relevant sections of financial reports produced by industry-matched samples of large-, mid- and small-cap UK-listed firms during the transitional 2013–2014 financial reporting years. Both specific and generic readability attributes of the reports are measured. We find that virtually no firm in our sample has provided any viability statement. Empirical analysis of disclosures concerning principal risk assessment and review processes appear to be primarily motivated by political visibility reasons. Examples of particularly good and cases of poor corporate risk reporting practices are also discussed. Possible implications for the actuarial profession are discussed.

AbstractObjectiveThis study was conducted for comparison of techniques between volumetric modulated arc therapy (VMAT), forward-planning intensity-modulated radiotherapy (FIMRT) and conventional technique for left-sided breast radiotherapy after conservative surgery.MethodsIn all, 20 postoperative left breast carcinoma patients were included in this study. In all plans the planning target volume (PTV) was the breast tissue with appropriate margin as per our institutional protocol. The contouring was done on a Monaco Sim (V5.00.02) contouring workstation. All patient were planned using partial arc VMAT in Monaco treatment planning system (TPS) (V5.00.02) and treated on Elekta Synergy linear accelerator. The 3D conformal radiotherapy (3DCRT) and FIMRT planning were done in CMS XIO (V5.00.01.1) TPS. The 3DCRT planning consisted of conventional medial and tangential wedge portals with multileaf collimator field shaping conforming to the target volume. For all the plans generated the following metrics were scored: V105%, V100%, V95%, mean dose (for PTV), V5%, V20%, D2cc and mean dose (for organs at risk).ResultsThe mean PTV volume for 20 patients was 1,074·6±405·1 cc. The highest PTV dose coverage was observed in the 3DCRT technique with 94·1±1·8% of the breast PTV receiving 95% of the prescription dose (V95%). However, it was also observed that this technique resulted in 21·3±10% of the PTV receiving more than 105% of the prescription dose (V105%), which was highest among the three techniques. In contrast, VMAT yielded lowest V95% of 93·0±1·8 and 3·3±5·5% of V105%.ConclusionThis study concluded equivalent result between FIMRT and VMAT. However, VMAT was found to be the choice of radiotherapy technique as it produces lesser dose distribution to heart compared with any other technique.
Tense, Time, Aspect and the Ancient Greek Verb
Authors: Moran Jerome 
Published: November 2016

Nearly every – no, every – Greek grammar and course book, even the most comprehensive (in English, at any rate), gives a very skimpy, perfunctory and unhelpful account — insofar as it gives any account at all – of what ‘aspect’ is and how exactly it is related to verb tense and time (which tend to be conflated). Most of the books and articles on the subject of the aspect of the Greek verb are accessible only to the professional philologist, and can't therefore be easily applied by non-specialists to the understanding of the actual usage of Greek writers or to the imitation of their usage when translating into their language. This article sets out to remedy this situation by giving a clear and (within limits) comprehensive explanation of aspect as it applies to the Greek verb.
