Collapse capacity of soil‐structure systems under pulse‐like earthquakes
Authors: Khoshnoudian Faramarz , Ahmadi Ehsan , Kiani Mahdi , Hadikhan Tehrani Mohammad 
Published: October 2014

SummaryIn this paper, a comprehensive study is carried out to examine the possibility of dynamic instability produced in soil‐structure systems using an ensemble of 50 pulse‐like records. A number of structural models with various vibration periods varying from 0.1 to 2 s are used in this study. The superstructure is simulated as a non‐linear SDOF oscillator with a two‐segment backbone curve having negative post‐yield stiffness. The soil is idealized based on the cone model concept widely used for practical purposes. The results of this investigation demonstrate that as the pulse period increases, the collapse relative lateral strength ratio decreases and probability of dynamic instability enhances. Moreover, soil flexibility makes the system dynamically more unstable, and as the non‐dimensional frequency increases, the collapse relative lateral strength ratio highly reduces. Additionally, the aspect ratio has insignificant effects on the collapse relative lateral strength ratio. Furthermore, comparison of the collapse relative lateral strength ratios resulting from pulse‐like motions with those obtained from studies under non‐pulse‐like motions (Miranda and Akkar; FEMA 440) for fixed‐base conditions shows that high‐velocity pulses exacerbate the dynamic instability problem and decrease the collapse relative lateral strength ratio.

Authors: Li Lydia W. , Liu Jinyu , Zhang Zhenmei , Xu Hongwei 
Published: October 2014

ObjectivesThis study aimed to examine whether physical infrastructure and availability of three types of community resources (old‐age income support, healthcare facilities, and elder activity centers) in rural villages are associated with depressive symptoms among older adults in rural China.MethodData were from the 2011 baseline survey of the Chinese Health and Retirement Longitudinal Study (CHARLS). The sample included 3824 older adults aged 60 years or older residing in 301 rural villages across China. A score of 12 on the 10‐item Center for Epidemiologic Studies Depression Scale was used as the cutoff for depressed versus not depressed. Village infrastructure was indicated by an index summing deficiency in six areas: drinking water, fuel, road, sewage, waste management, and toilet facilities. Three dichotomous variables indicated whether income support, healthcare facility, and elder activity center were available in the village. Respondents' demographic characteristics (age, gender, marital status, and living arrangements), health status (chronic conditions and physical disability), and socioeconomic status (education, support from children, health insurance, household luxury items, and housing quality) were covariates. Multilevel logistic regression was conducted.ResultsControlling for individuals' socioeconomic status, health status, and demographic characteristics, village infrastructure deficiency was positively associated with the odds of being depressed among rural older Chinese, whereas the provision of income support and healthcare facilities in rural villages was associated with lower odds.ConclusionVillage infrastructure and availability of community resources matter for depressive symptoms in rural older adults. Improving infrastructure, providing old‐age income support, and establishing healthcare facilities in villages could be effective strategies to prevent late‐life depression in rural China.

AbstractBackgroundThe impact of comorbidities on patients with advanced head and neck cancer treated with major surgery has not been reported before.MethodsWe retrospectively reviewed clinical charts between 2004 and 2011 at our institution and identified 185 patients with clinical stage III to IV head and neck cancer treated with major surgery. Comorbidities were scored using the Adult Comorbidity Evaluation‐27 (ACE‐27) index manual.ResultsPatients with ACE‐27 ≥2 had significantly worse overall survival (OS) and disease‐specific survival (DSS) than those with ACE‐27 ≤1 (p < .0001 and p = .0047, respectively). Multivariate analyses revealed that ACE‐27 ≥2 and extracapsular spread (ECS) were independently significant adverse prognostic factors for OS and DSS. In addition, patients with ACE‐27 ≥2 had a higher incidence of distant metastases (p = .0057).ConclusionThe current study suggests that comorbidities may predict poor prognosis and development of distant metastases for patients with advanced head and neck cancer treated with major surgery. © 2015 Wiley Periodicals, Inc.

ABSTRACTβ‐catenin is a central effector of the Wnt pathway and one of the players in Ca+‐dependent cell‐cell adhesion. While many wnts are present and expressed in vertebrates, only one β‐catenin exists in the majority of the organisms. One intriguing exception is zebrafish that carries two genes for β‐catenin. The maternal recessive mutation ichabod presents very low levels of β‐catenin2 that in turn affects dorsal axis formation, suggesting that β‐catenin1 is incapable to compensate for β‐catenin2 loss and raising the question of whether these two β‐catenins may have differential roles during early axis specification. Here we identify a specific antibody that can discriminate selectively for β‐catenin1. By confocal co‐immunofluorescent analysis and low concentration gain‐of‐function experiments, we show that β‐catenin1 and 2 behave in similar modes in dorsal axis induction and cellular localization. Surprisingly, we also found that in the ich embryo the mRNAs of the components of β‐catenin regulatory pathway, including β‐catenin1, are more abundant than in the Wt embryo. Increased levels of β‐catenin1 are found at the membrane level but not in the nuclei till high stage. Finally, we present evidence that β‐catenin1 cannot revert the ich phenotype because it may be under the control of a GSK3β‐independent mechanism that required Axin's RGS domain function. J. Cell.

PPAR‐γ Promotes Endothelial Cell Migration By Inducing the Expression of Sema3g
Authors: Liu Weiwei , Li Jingjin , Liu Min , Zhang Hong , Wang Nanping 
Published: October 2014

ABSTRACTIn addition to regulating lipid and glucose metabolism, the nuclear receptor PPAR‐γ has emerged as a potentially relevant player in regulating endothelial cell function. Despite the identification of numerous PPAR‐γ targets involved in vascular development, the targets downstream of PPAR‐γ that directly affect endothelial cell function remain to be elucidated. In this report, we identify Sema3g as a novel PPAR‐γ‐regulated gene playing a substantial role in endothelial biology, particularly with respect to endothelial cell migration. Sema3g expression is induced by either overexpression of PPAR‐γ or PPAR‐γ ligands treatment in human umbilical vein endothelial cells (HUVECs). Chromatin immunoprecipitation (ChIP) and transient transfection assays revealed that PPAR‐γ binds to the Sema3g promoter and activates transcription. Furthermore, we show that overexpression of Sema3g augments PPAR‐γ‐driven HUVECs migration, whereas silencing of Sema3g expression almost completely abrogates PPAR‐γ or Sema3g‐mediated cell migration. Accordingly, the anti‐neuropilin‐2 (Sema3g receptor) neutralizing antibody treatment markedly inhibits Sema3g‐induced cell migration. Collectively, these results identify Sema3g as one of the downstream effectors of PPAR‐γ, which is centrally involved in regulating endothelial cell migration. J. Cell.

Published: October 2014

AbstractBACKGROUNDα‐Dicarbonyl compounds (α‐DCs) such as 3‐deoxyglucosone (3‐DG) and glucosone are markers of both Maillard and degradation reactions of sugars and also of certain enzymatic processes. However, quantitation of these compounds is not straightforward when more abundant carbohydrates are present in real samples. Therefore in this work a GC/MS method was developed to separate monosaccharides, 3‐DG and glucosone and applied to analyze them in carbohydrate‐rich food products. Difructose anhydrides (DFAs), known markers of sugar degradation, were also determined. The effect of time and temperature in the production and storage of these compounds was also evaluated.RESULTSUnder optimized conditions, good separation between monosaccharides and α‐DCs was achieved. Must syrups showed the highest concentrations of 3‐DG and glucosone (average values 9.2 and 5.8 mg g−1 respectively). Coffee substitutes based on carob, chicory and blends showed the highest content of DFAs. Heating and storage assays proved that production of 3‐DG was influenced by temperature, while glucosone was more affected by storage time.CONCLUSIONThe proposed method allows the rapid quantitation of 3‐DG and glucosone along with carbohydrates and DFAs in different food products, which is essential to determine their degradation level. Moreover, the α‐DC content in several foods is reported for the first time. © 2014 Society of Chemical Industry
Resistant starch in food: a review
Authors: Raigond Pinky , Ezekiel Rajarathnam , Raigond Baswaraj 
Published: October 2014

AbstractThe nutritional property of starch is related to its rate and extent of digestion and absorption in the small intestine. For nutritional purposes, starch is classified as rapidly available, slowly available and resistant starch (RS). The exact underlying mechanism of relative resistance of starch granules is complicated because those factors are often interconnected. The content of RS in food is highly influenced by food preparation manner and processing techniques. Physical or chemical treatments also alter the level of RS in a food. Commercial preparations of RS are now available and can be added to foods as an ingredient for lowering the calorific value and improving textural and organoleptic characteristics along with increasing the amount of dietary fiber. RS has assumed great importance owing to its unique functional properties and health benefits. The beneficial effects of RS include glycemic control and control of fasting plasma triglyceride and cholesterol levels and absorption of minerals. This review attempts to analyze the information published, especially in the recent past, on classification, structure, properties, applications and health benefits of RS. © 2014 Society of Chemical Industry

PurposeTo develop and validate a method for acquiring helium‐3 (3He) and proton (1H) three‐dimensional (3D) image sets of the human lung with isotropic spatial resolution within a 10‐s breath‐hold by using compressed sensing (CS) acceleration, and to assess the fidelity of undersampled images compared with fully sampled images.MethodsThe undersampling scheme for CS acceleration was optimized and tested using 3He ventilation data. Rapid 3D acquisition of both 3He and 1H data during one breath‐hold was then implemented, based on a balanced steady‐state free‐precession pulse sequence, by random undersampling of k‐space with reconstruction by means of minimizing the L1 norm and total variance. CS‐reconstruction fidelity was evaluated quantitatively by comparing fully sampled and retrospectively undersampled image sets.ResultsHelium‐3 and 1H 3D image sets of the lung with isotropic 3.9‐mm resolution were acquired during a single breath‐hold in 12 s and 8 s using acceleration factors of 2 and 3, respectively. Comparison of fully sampled and retrospectively undersampled 3He and 1H images yielded mean absolute errors <10% and structural similarity indices >0.9.ConclusionBy randomly undersampling k‐space and using CS reconstruction, high‐quality 3He and 1H 3D image sets with isotropic 3.9‐mm resolution can be acquired within an 8‐s breath‐hold.

AbstractThe geometric process is considered when the distribution of the first interarrival time is assumed to be Weibull. Its one‐dimensional probability distribution is derived as a power series expansion of the convolution of the Weibull distributions. Further, the mean value function is expanded into a power series using an integral equation. © 2014 Wiley Periodicals, Inc. Naval Research Logistics, 61: 599–603, 2014

AbstractObjectiveA haematological malignancy is a serious, life‐altering disease and may be characterised as an uncontrollable and unpredictable stress situation. In dealing with potentially threatening information, individuals generally utilise two main cognitive coping styles: monitoring (the tendency to seek threat‐relevant information) and blunting (avoiding threatening information and seeking distraction). The aim of this study was to obtain insight into the association between cognitive coping style and (a) need for information, (b) satisfaction with information, (c) involvement in decision making, and (d) quality of life (QoL).MethodsIn this cross‐sectional study, coping style was assessed among adult patients diagnosed with a haematological malignancy, using an adapted version of the Threatening Medical Situations Inventory. Information need, information satisfaction, decision‐making preference and QoL were measured with validated questionnaires.ResultsIn total, 458 patients returned the questionnaire (66%). A monitoring coping style was positively related to need for both general and specific information. Blunting was positively and QoL was negatively related to need for information. Monitoring was positively related to involvement in decision‐making and negatively to information satisfaction. Using multivariate analysis, this relation between monitoring and information satisfaction disappeared, and for blunting, we found a negatively significant relation. QoL was not related to coping style.ConclusionsAmong patients with haematological malignancies, coping style is related to a need for information, information satisfaction, and involvement in treatment decision‐making. Therefore, it is important for health care professionals to be aware of individual differences in cognitive coping style. Copyright © 2014 John Wiley & Sons, Ltd.
Casimir interactions in strained graphene systems
Authors: Phan Anh D. , Phan The‐Long 
Published: October 2014

We theoretically study the strain effect on the Casimir interactions in graphene based systems. We found that the interactions between two strained graphene sheets are strongly dependent on the direction of stretching. The influence of the strain on the dispersion interactions is still strong in the presence of dielectric substrates but is relatively weak when the substrate is metallic. Our studies would suggest new ways to design next generation devices.

Authors: Ranganathan Chitra , Montemayor Raymond 
Published: October 2014

ABSTRACTThe purpose of this study was to investigate the relationship between parental efficacy and a new concept entitled parental monitoring efficacy, and to examine the association between parental monitoring efficacy and monitoring. We conducted two studies on two samples of Asian‐Indian parents and adolescents living in Chennai, India. In the first study of 241 parents of adolescents in grades, 9–12, we constructed a new measure of parental efficacy that included two factors. The first factor, responding competently to negative adolescent behavior was more strongly predictive of parental monitoring efficacy than the second factor, instilling positive behavior. In the second study of 215 parents and adolescents in grades 10 and 12, parental monitoring efficacy predicted monitoring, especially adolescent disclosure and parental control. The importance of parental control as a monitoring technique among traditional Indian parents was discussed.

ABSTRACTAdolescence is a crucial phase of human life characterized by enhanced exposure and vulnerability to various stressful stimuli. The Adolescent Stress Questionnaire (ASQ) is a useful measure to evaluate possible sources of stressors affecting the adolescent equilibrium. The present study examines the scientific properties of the Greek version of ASQ to measure perceived stress among 250 Greek adolescents. The confirmatory factor analysis (CFA) results showed a good fit of the original structure of ASQ to the observed data in the Greek sample. A good internal reliability was also confirmed by high Cronbach's alpha values. In line with previous research, girls reported more stress than boys. Overall, the Greek ASQ is a valid and reliable instrument for evaluating adolescent stress.

Published: October 2014

AbstractIn the present paper, the problem on normal low-velocity impact of a solid upon an isotropic spherical shell is studied without considering the changes in the geometrical dimensions of the contact domain. At the moment of impact, shock waves (surfaces of strong discontinuity) are generated in the target, which then propagate along the shell during the process of impact. Behind the wave fronts up to the boundary of the contact domain, the solution is constructed with the help of the theory of discontinuities and one-term ray expansions. The ray method is used outside the contact spot, but the Laplace transform method is applied within the contact region. As a result, the exact solution of the contact force is determined as a function of time. This model is intended to be used in simulating crash scenarios in frontal impacts, and to provide an effective tool to estimate the severity of effect on the human head and to estimate brain injury risks.
Optimization of Rectangular Multi-Chamber Plenums Equipped with Multiple Extended Tubes Using the BEM, Neural Networks, and the Genetic Algorithm

Published: October 2014

AbstractThe focal point of this paper is to uncover, by analyzing the higher order wave effect, an improved mechanism for space-constrained rectangular plenums using a simplified objective function in conjunction with a genetic (GA). Three kinds of rectangular mufflers hybridized with extended tubes will be assessed: Plenum A: A two-chamber plenum equipped with an extended tube; plenum B: A three-chamber plenum with two extended tubes; and plenum C: A two-chamber plenum equipped with three extended tubes. In order to shorten the numerical assessment, a simplified objective function (OBJ) is established using a boundary element model (BEM) in conjunction with the neural network model (NNM). To expediently approach an optimal plenum, the best OBJ will be numerically searched using a genetic algorithm (GA). However, before the GA operation is performed, the accuracy of the BEM is verified using analytical data. And, because the simplified objective function (OBJ) is seen to be in agreement with the BEM, the numerical cases of sound elimination relative to the various parameter sets and pure tones (300, 750, and 1300Hz) can be carried out.Results reveal that the maximum value of the sound transmission loss (STL) can be accurately obtained at the desired frequencies. Additionally, the acoustical performance of the lower frequencies will be improved if the number of chambers and rectangular tubes are increased. However, the acoustical performance of the higher frequencies will decrease when the number of chambers and rectangular tubes are decreased. Consequently, the algorithms proposed in this study will efficiently develop optimal rectangular plenums with multiple rectangular extended tubes.

Authors: Seth G. S. , Sarkar S. 
Published: October 2014

AbstractAn investigation of unsteady hydromagnetic natural convection heat and mass transfer flow of an electrically conducting, viscous, incompressible and optically thick radiating fluid past an impulsively moving infinite vertical plate embedded in a uniform porous medium in a rotating system with Hall effects in the presence of homogeneous first order chemical reaction is carried out when temperature of the plate has a temporarily ramped profile. Exact solution of the governing equations is obtained in closed form by Laplace transform technique. Expressions for skin friction due to primary and secondary flows and Nusselt number are derived for both ramped temperature and isothermal plates. Expression for Sherwood number is also derived. The numerical values of primary and secondary fluid velocities, fluid temperature and species concentration are displayed graphically whereas those of skin friction are presented in tabular form for various values of pertinent flow parameters. In order to highlight the influence of ramped temperature distribution within the plate on the flow-field, the fluid flow past a ramped temperature plate is compared with the one past an isothermal plate.
