The interaction in the molten system Rb2O‐P2O5‐TiO2‐NiO was investigated at different molar ratios Rb/P = 0.5‐1.3, fixed Ti/P = 0.15, Ti/Ni = 1.0 at temperature range 1073–953 K. The conditions of formation of complex phosphates RbTi2(PO4)3, Rb2Ni0.5Ti1.5(PO4)3 and RbNiPO4 have been determined. The new phosphate Rb2Ni0.5Ti1.5(PO4)3 (space group P213, a = 9.9386(2) Å) has been obtained and investigated by the single crystal X‐ray diffraction and FTIR‐spectroscopy. It has langbeinite‐like structure, that is built up from mixed (Ni/Ti)O6‐octahedra and РО4‐tetrahedra. Rubidium atoms are located in closed cavities of 3D‐framework.

Published: May 2015

SummaryMobile learning can augment formal education and bridge the gap between formal and informal education by creating extended learning communities using any digital technology in connected or infrastructure‐less environments. With the use of ad hoc networks and mobile authoring tools, we can now create an ‘on‐the‐fly’ learning scenario, where learners can create, share, and view content from their mobile devices without the need for server–client or infrastructure‐based liaisons. Mobile learning, however, is not just about sharing content or learning using mobile, wireless, and portable devices. Rather, it is learning across spatiotemporal contexts that enables learners to form knowledge and understanding in different scenarios. When facing limited resources stemming from the characteristics of mobility and wireless technologies, determining the best practices for content creation and delivery becomes a challenge. This paper describes the architecture of a mobile‐focused learning network designed so that learning tools, activities, contexts, and interactions are created as necessary over time and space while adhering to traditional learning object standards.

Does depression matter in neuropsychological performances in anorexia nervosa? A descriptive review
Authors: Abbate‐Daga Giovanni , Buzzichelli Sara , Marzola Enrica , Aloi Matteo , Amianto Federico , Fassino Secondo 
Published: May 2015

ABSTRACTObjectiveThis review aims to examine the impact of depressive symptoms on the assessment of cognitive flexibility, central coherence, and decision‐making in individuals with anorexia nervosa (AN).MethodAn online search was carried out using PubMed and PsycInfo. Articles were selected for review if they were published in English between 1990 and 2014 and used the Wisconsin Card Sorting Test, the Trail Making Task parts A and B, the Brixton Test, the Rey‐Osterrieth Complex Figure Test, and/or the Iowa Gambling Task.ResultsSixty‐two studies were included. Thirty (48%) of the studies statistically assessed the association between depression and neurocognition in AN versus healthy controls. Where significant correlations were found, it became clear that the more serious the depression, the greater the neuropsychological impairment. Only six (10%) studies examined whether increased depressive symptoms were able to eliminate the differences between individuals with AN and healthy controls, and one study found that depressive symptoms did eliminate group differences in cognitive flexibility and decision‐making.DiscussionOnly a subgroup of articles on neuropsychology in AN adjusted for depression. However, given the role of depression that some articles suggest, future studies should pay closer attention to the evaluation of this potential confounder. © 2015 Wiley Periodicals, Inc.

Authors: Kothari Radha , Easter Abigail , Lewis Rebecca , Howard Louise M. , Micali Nadia 
Published: May 2015

ABSTRACTObjective Prevalence of intimate partner violence (IPV) during pregnancy is estimated to be 4%–8%. Women with mental health difficulties are at increased risk for IPV during the perinatal period. Prevalence of IPV is high among women with eating disorders (ED); however, prevalence of IPV during the perinatal period among women with ED is unknown.Method We studied women from a population‐based cohort, the Avon Longitudinal Study of Parents and Children. Prevalence and odds of physical and emotional IPV during and after the perinatal period was investigated among women with lifetime ED, with (n = 174) or without pregnancy shape and weight concern and/or purging behaviors (n = 189), and women with no ED (n = 8723).Results Women with lifetime ED showed higher prevalence of IPV during and after the perinatal period (physical = 9.6%–14.3% and emotional = 24.1%–28.1%). Lifetime ED was associated with higher odds of physical IPV during the perinatal period (odds ratio: 2.34, 95% confidence interval: 1.11–4.93, p = .03). Lifetime ED with and without pregnancy shape and weight concerns and/or purging was associated with higher odds of IPV after the perinatal period, and higher odds of reporting emotional IPV at all time points. Associations were moderated by partner's response to pregnancy and maternal experience of childhood sexual abuse.Discussion Mothers with ED and their children may be vulnerable to negative effects due to maternal ED and IPV combined, both of which have been associated with severe and long‐lasting harmful consequences. Partner's response to pregnancy and maternal experience of childhood sexual abuse might contribute to the association between ED and IPV perinatally. © 2015 The Authors.

AbstractBackgroundMethods for the detection of the temporal and spatial generation of painful symptoms are needed to improve the diagnosis and treatment of painful neuropathies and to aid preclinical screening of molecular therapeutics.MethodsIn this study, we utilized in vivo luminescent imaging of NF‐κB activity and serum cytokine measures to investigate relationships between the NF‐κB regulatory network and the presentation of painful symptoms in a model of neuropathy.ResultsThe chronic constriction injury model led to temporal increases in NF‐κB activity that were strongly and non‐linearly correlated with the presentation of pain sensitivities (i.e. mechanical allodynia and thermal hyperalgesia). The delivery of NEMO‐binding domain peptide reduced pain sensitivities through the inhibition of NF‐κB activity in a manner consistent with the demonstrated non‐linear relationship. Importantly, the combination of non‐invasive measures of NF‐κB activity and NF‐κB‐regulated serum cytokines produced a highly predictive model of both mechanical (R2 = 0.86) and thermal (R2 = 0.76) pain centred on the NF‐κB regulatory network (NF‐κB, IL‐6, CXCL1).ConclusionsUsing in vivo luminescent imaging of NF‐κB activity and serum cytokine measures, this work establishes NF‐κB and NF‐κB‐regulated cytokines as novel multivariate biomarkers of pain‐related sensitivity in this model of neuropathy that may be useful for the rapid screening of novel molecular therapeutics.
Ethylene vinyl acetate/poly(ethylene glycol) blend membranes for CO2/N2 separation
Authors: Zamiri Mohammad Amin , Kargari Ali , Sanaeepur Hamidreza 
Published: May 2015

AbstractIn this paper, novel membranes were prepared from blending the ethylene vinyl acetate (EVA), containing 28 wt.% of vinyl acetate, and poly(ethylene glycol) (PEG) (0–20 wt.%) with molecular weights of 200, 1000, and 1500, and considered for CO2/N2 separation over the feed pressure of range 2–8 bar. Physical properties and the morphology of the membranes were evaluated by Fourier transform infrared (FTIR) spectroscopy, differential scanning calorimetry (DSC), X‐ray diffraction (XRD), and scanning electron microscope (SEM) analyses in order to justify the gas permeation and separation performance of the membranes. The results showed that CO2 permeability increases by increasing the PEG content of the blend membranes. However, increasing PEG loading enhanced CO2/N2 selectivity just for the blends containing up to 10 wt.% of PEG and it decreased at higher PEG loadings. The PEG with a molecular weight of 200 showed a more efficient gas separation performance due to its effective role in providing amorphous regions in the blends. Furthermore, higher CO2 permeabilities were obtained at higher feed pressures. The selectivity increased by increasing the feed pressure for neat EVA, EVA/5 wt.% PEG and EVA/10 wt.% PEG membranes, but it had no significant effect on the selectivity of the samples with 15 and 20 wt.% of PEG.© 2015 Society of Chemical Industry and John Wiley & Sons, Ltd
Meso‐Cenozoic thermal structure of the lithosphere in the Bohai Bay Basin, eastern North China Craton
Authors: Qiu Nansheng , Zuo Yinhui , Xu Wei , Chang Jian 
Published: May 2015

AbstractThermal structure of the lithosphere studies the partition of crustal and mantle heat flow of the continental area and is of significant importance to understand various energy‐related geodynamic processes. The study addresses the spatial distribution of the Meso‐Cenozoic mantle heat flow and Moho temperatures in the region of the Bohai Bay Basin based on the thermal history of the sedimentary basin, radioactive heat production rate and thickness of crustal layering. The results show that the ratio of the mantle and surface heat flow (qm/qs) experienced two peaks in the late period of the Early Cretaceous (qm/qs ~ 68%) and the Middle to Late Palaeogene (qm/qs ~ 75%), respectively. Based on the qm/qs ratio, the lithosphere of the Bohai Bay Basin transformed its thermal structure during the Meso‐Cenozoic, from the ‘cold mantle but hot crust’ stage in the Triassic–Jurassic to the ‘hot mantle but cold crust’ stage in the Cretaceous and Cenozoic. The Moho temperatures (Tm) during the Meso‐Cenozoic were also calculated by using the equation of one‐dimensional heat conduction, and the result shows that there exist three Tm peaks occurring in the late period of the Early Cretaceous (930–1080 °C), the Middle‐Late Palaeogene (820–890 °C) and the Early Neogene (770–810 °C). The qm/qs ratio began to exceed 50%, and the Moho temperature started to go over 700 °C from the Cretaceous to the present day, which revealed that the activity of the upper mantle in the eastern North China Craton (NCC) increased significantly accompanied by the strong crustal movement in the Cretaceous. The thermal structure revealed the Cretaceous to be a revolutionary period during the evolution of the Bohai Bay Basin, and this paper may provide some thermal evidence for the studies of the geodynamic evolution during the destruction of the NCC.

Use of stable water isotopes to identify hydrological processes of meteoric water in montane catchments

Published: May 2015

AbstractThis study analyzes the stable isotopic compositions of hydrogen and oxygen (δ2H, δ18O) in montane meteoric waters including precipitation and stream water of central Taiwan to identify hydrological processes in montane catchments. Results of precipitation demonstrate that monsoon and altitude effects are two principal processes affecting δ and deuterium excess (dE) values of inland precipitation in central Taiwan. Furthermore, slope and intercept values of summer and winter local meteoric water line are modified by secondary evaporation effects such as moisture recycling and raindrop evaporation. Additionally, stream water's results indicate that differences in δ values among stream waters reflect isotopic altitude effect whereby lower values are more evident in stream water originating from high‐elevation catchments than low‐elevation catchments. Comparison of the isotopic results between precipitation and stream water indicates that summer precipitation containing recycled moisture is the most important water source for the studied stream waters and indicates that catchment effect and base flow contribution are the two major hydrological processes affecting mountain stream hydrology. The hydrological processes identified by the isotopic study re‐stress the important role of forests in mountain hydrology. Copyright © 2015 John Wiley & Sons, Ltd.

ABSTRACTSeeding cells efficiently and uniformly onto three‐dimensional scaffolds is key for engineering urological tissue with an ideal histological structure in vitro. Using an optimized seeding technology allows cells to cooperate positively with biomaterials, resulting in successful reconstructive surgery. In this study, we used four different types of seeding methods in a scaffold of small intestinal submucosa (SIS). The efficiency of the sandwich co‐culture, layered co‐culture, static‐agitation seeding, and centrifugation seeding methods were compared. It was demonstrated that dynamic seeding methods, such as static‐agitation and centrifugation seeding, had superior cell‐matrix infiltration and mechanical properties. The seeding time could be reduced by 5–10 min using the centrifugation method. Furthermore, functional assessment of the barriers revealed that this function was better in the centrifugation seeding method than in any other method. Our study suggests that both the static‐agitation and centrifugation methods are suitable for cell seeding on SIS. There is no significant change in surface area of SIS with different seeding methods. These methods reinforce the physiological and mechanical properties of biomaterials and allow for the future in vivo study of tissue‐engineered urethral reconstruction. © 2015 Wiley Periodicals, Inc.

Published: May 2015

INTRODUCTIONTimely and reliable verbal communication between hospitalists and primary care physicians (PCPs) is critical for prevention of medical adverse events but difficult in practice. Our aim was to increase the proportion of completed verbal handoffs from on‐call residents or attendings to PCPs within 24 hours of patient discharge from a hospital medicine service to ≥90% within 18 months.METHODSA multidisciplinary team collaborated to redesign the process by which PCPs were contacted following patient discharge. Interventions focused on the key drivers of obtaining stakeholder buy‐in, standardization of the communication process, including assigning primary responsibility for discharge communication to a single resident on each team and batching calls during times of maximum resident availability, reliable automated process initiation through leveraging the electronic health record (EHR), and transparency of data. A run chart assessed the impact of interventions over time.RESULTSThe percentage of calls initiated within 24 hours of discharge improved from 52% to 97%, and the percentage of calls completed improved to 93%. Results were sustained for 18 months. Standardization of the communication process through hospital telephone operators, use of the discharge order to ensure initiation of discharge communication, and batching of phone calls were associated with improvements in our measures.CONCLUSIONReliable verbal discharge communication can be achieved through the use of a standardized discharge communication process coupled with the EHR.

ScopeThere is strong epidemiological evidence indicating that consumption by humans of whole‐grain foods including rice bran may be associated with a low incidence of cancer, especially in the colorectum. Molecular processes associated with cancer development may be retarded by fiber consumption. Consequently, intervention with dietary fiber might be suitable as a cancer chemoprevention strategy in high‐risk populations. Here, we searched for putative molecular mechanism‐based efficacy biomarkers of rice fiber consumption in the plasma of mice characterized by a genetic propensity to develop gastrointestinal adenomas. The hypothesis was tested that metabolic and proteomic changes in blood reflect the chemopreventive activity of rice bran.Methods and resultsApcMin mice received diet supplemented with rice bran at 5, 15, and 30%. Blood and tissue samples were taken. Plasma was subjected to MS‐based proteomic and metabolic profiling analyses as well as assessment of hematocrit values. Gastrointestinal tracts were removed and adenomas were counted and their size was measured so that total tumor burden could be calculated. The hypothesis was tested that metabolic and proteomic changes in blood reflect chemopreventive activity.ConclusionRice bran consumption reduced adenoma burden and number in a dose‐related fashion when compared to controls. Metabolic profiling data demonstrated strong clustering of the groups indicating that metabolic pathways are perturbed. Proteomic analysis identified adiponectin as a molecule that was significantly altered, which may play a role in tumor suppression.
Locking‐free discontinuous finite elements for the upper bound yield design of thick plates
Authors: Bleyer Jeremy , Van Le Canh , de Buhan Patrick 
Published: May 2015

SummaryThis work investigates the formulation of finite elements dedicated to the upper bound kinematic approach of yield design or limit analysis of Reissner–Mindlin thick plates in shear‐bending interaction. The main novelty of this paper is to take full advantage of the fundamental difference between limit analysis and elasticity problems as regards the class of admissible virtual velocity fields. In particular, it has been demonstrated for 2D plane stress, plane strain or 3D limit analysis problems that the use of discontinuous velocity fields presents a lot of advantages when seeking for accurate upper bound estimates. For this reason, discontinuous interpolations of the transverse velocity and the rotation fields for Reissner–Mindlin plates are proposed. The subsequent discrete minimization problem is formulated as a second‐order cone programming problem and is solved using the industrial software package MOSEK. A comprehensive study of the shear‐locking phenomenon is also conducted, and it is shown that discontinuous elements avoid such a phenomenon quite naturally whereas continuous elements cannot without any specific treatment. This particular aspect is confirmed through numerical examples on classical benchmark problems and the so‐obtained upper bound estimates are confronted to recently developed lower bound equilibrium finite elements for thick plates.

Laplace‐domain, high‐order homogenization for transient dynamic response of viscoelastic composites
Authors: Hui Tong , Oskay Caglar 
Published: May 2015

SummaryThis paper presents a high‐order homogenization model for wave propagation in viscoelastic composite structures. Asymptotic expansions with multiple spatial scales are employed to formulate the homogenization model. The proposed multiscale model operates in the Laplace domain allowing the representation of linear viscoelastic constitutive relationship using a proportionality law. The high‐order terms in the asymptotic expansion of response fields are included to reproduce micro‐heterogeneity‐induced wave dispersion and formation of bandgaps. The first and second‐order influence functions and the macroscopic deformation are evaluated using the finite element method with complex coefficients in the Laplace domain. The performance of the proposed model is assessed by investigating wave propagation characteristics in layered and particulate composites and verified against direct numerical simulations and analytical solutions. The analysis of dissipated energy revealed that material dispersion may contribute significantly to wave attenuation in dissipative composite materials. The wave dispersion characteristics are shown to be sensitive to microstructure morphology. Copyright © 2015 John Wiley & Sons, Ltd.
Modified correlation entropy of a gated nanowire system described by a numerically determined non‐equilibrium many‐body statistical operator
Authors: Castelo José María , Indlekofer Klaus Michael 
Published: May 2015

AbstractA numerical correlation measure of the interacting electrons in a semiconductor nanowire‐based field‐effect transistor (NWFET) is presented, which solely quantifies correlation whether the preparation of the system is pure or mixed, in contrast to the single‐particle‐reduced entropy, which depends on the degree of correlation and mixture as well. This numerical measure, which is termed modified correlation entropy , is based on the concept of von Neumann entropy, whose calculation is dependent on the non‐equilibrium many‐body statistical operator of the system. Therefore, we present a numerical approach to construct such a non‐equilibrium many‐body statistical operator for relevant quasi‐bound electronic states in a NWFET. As a constraint for , we assume that the single‐particle density matrix is a given quantity, resulting from a non‐equilibrium Green's function (NEGF) calculation for the NWFET for a given set of applied voltages. The eigenbasis of is assumed to be identical to the eigenbasis of the projected many‐body Hamiltonian within a relevant Fock subspace of the quasi‐bound subsystem. As for the eigenvalues of , we furthermore assume that have a generalized Boltzmann form, parameterized by effective electrochemical potentials of natural orbitals and a given temperature. Once is obtained, we calculate and compare the modified entropy , the single‐particle‐reduced entropy and the von Neumann entropy S for two different transport regimes of the NWFET.
