A Comparative Study on the Luminescence of the Cd2+ and Mn2+ Coordination Polymers Based on the Same Mixed Ligands
Authors: Wu Zhaofeng , Huang Xiaoying 
Published: June 2016

AbstractPresented here is the solvothermal preparation of two luminescent coordination polymers (L‐CPs) based on the same mixed ligands, namely [Cd2(1,4‐NDC)2(dppe)] (1) and [Mn3(OH)2(1,4‐NDC)2(dppe)(H2O)] (2) (1,4‐NDCH2=1,4‐naphthalene dicarboxylic acid, dppe=1,3‐di(4‐pyridyl)propane). Both the title compounds feature a neutral three‐dimensional (3D) network. Photoluminescence (PL) studies indicated that the compound 1 based on d10 Cd2+ exhibited dual emissions with tunable intensities that could result in direct white‐light emission based on the intraligand charge transfer (LLCT); while the compound 2 showed a single band of yellow emission based on the charge transfer between the ligands and the metal ion (LMCT), due to the partially filled d‐orbital of Mn2+ ion. The temperature‐dependent powder X‐ray diffraction patterns (PXRD) and PL spectra were further measured to identify their thermal stabilities. This work may provide a certain guiding significance for exploiting L‐CPs based on different metal ions.

Published: June 2016

AbstractMnO2/polyaniline/graphene composite as a supercapacitor electrode material was synthesized through an interfacial polymerization approach in the interface of oil/water phase. The as‐synthesized MPG is characterized by infrared spectroscopy, XRD, XPS, SEM and TEM, and its electrochemical performance is measured by cyclic voltammetry, galvanostatic charge/discharge, and electrochemical impedance spectroscopy. The 3D nanostructure of MPG and loose nanorod structure of polyaniline (PANI) coated with round MnO2 pellets could be clearly observed. The maximum energy density of MPG is 45.4 Wh/kg (at a power density of 67.8 kW/kg) and the highest power density is 229.2 kW/kg (at an energy density of 25.7 Wh/kg). The capacitance retentions after 500 cycles at the scan rate of 5 mV/s for MGP composite and PANI/graphene are 70.4% and 59.1%, respectively, and the capacitance values after 500 cycles are 158.4 F/g and 114.8 F/g, respectively. The improved performance of MPG is due to the 3D nanostructure, loose nanorod structure of PANI and stable support of graphene, which prevent the mechanical deformation effectively during the fast charge/discharge process and facilitate the diffusion of the electrolyte ions into the inner region of active materials. The composite material is very promising for the next generation of high‐performance supercapacitors electrode.
Structural Insights into Solid‐to‐Solid Phase Transition and Modulated Crystal Formation in Octyl‐β‐d‐Galactoside Crystals

Published: June 2016

AbstractDespite the significance of synthetic monotailed β‐linked galactolipids, for a detailed understanding of natural galactolipids, many aspects of these β‐linked galactolipids’ crystal structures such as temperature‐dependence and hydration characteristics remain inadequately understood. In this manuscript, we demonstrated detailed insight of crystal characteristics of one of the simplest monotailed galactolipids, octyl‐β‐d‐galactoside (MOβ‐Gal), using thermal analyses, Fourier‐transform infrared spectroscopy (FTIR), powder X‐ray diffraction (PXRD) measurements and grazing‐incidence wide‐angle X‐ray diffraction (GI‐WAXD) analysis. As a result, it was revealed that the MOβ‐Gal anhydrous crystal showed a continuous structural change from the high‐symmetry structure to low‐symmetry crystal lattice via the strengthened hydrogen bonding interaction as the temperature decreased. In addition, the hemihydrate crystal was found to be in the modulated “ribbon phase”. These insights strongly suggest that β‐linked galactolipids possess intrinsic characteristics necessary to form a modulated structure even in the crystal state and demonstrate the importance of the presence of tiny amounts of water as cushioning media for preventing order parameter evolution.

Published: June 2016

AbstractBackgroundEstablishment of cutpoints for classifying mild, moderate and severe pain is commonly based on single rating of worst or average pain. However, single pain measure may serve as a brief and partial surrogate for composite pain ratings. This study aimed to base composite pain ratings to establish optimal cutpoint that maximized the difference of pain interference on daily function and compare its utility with those based on single worst and average pain.MethodsData were from a cohort study of 322 patients with chronic pain. Brief pain inventory (including four items measuring the least, worst, average and current pain) was administered. Rasch analysis and Serlin et al.'s (Pain, 61, 1995, 277) method were used to derive optimal cutpoint.ResultsRasch analysis calibrated the least, worst, average and current pain items into a unidimensional hierarchy and produced composite pain measurement. The optimal cutpoint for composite pain (mild, ≤4; moderate, >4−6; severe, >6−10 on the 0−10 numeric rating scale) differed from those cutpoints for worst (≤6; >6−8; >8−10) and average pain (≤5; >5−7; >7−10). The optimal cutpoint for composite pain was better able than those for worst and average pain to distinguish among groups on patient‐rated pain quality and quality of life. The optimal cutpoint for average pain had better discriminant ability than that for worst pain.ConclusionThe results suggest that using optimal cutpoint for composite pain may be useful to classify clinically important groups in patients with chronic pain and that average pain may be an alternative choice if a single item is used.What does this study add?Using composite pain, optimal classification for mild, moderate and severe pain exhibited better discriminant ability than using single worst/average pain. The difficulty hierarchy of the least, worst, average and current pain helps to screen people with irregular responses.

Published: June 2016

AbstractA simple and sensitive nanobiosensor was developed for diagnosing label‐free, PCR‐free of rfbE gene in Escherichia coli O157 : H7 real sample. The Au nanoparticles modified electrode (AunanoME) was prepared by electrodeposition technique. The single‐stranded DNA probes were immobilized through the chemisorptions process on AunanoME (ssDNA/AunanoME). Electrochemical impedance spectroscopy (EIS) technique has been used to investigate the hybridization and sensing properties. Using electrochemical impedance spectroscopy (EIS) technique, the charge‐transfer resistance (Rct) values were raised by immobilization of the DNA probe and after the hybridization with the complementary oligonucleotide for ssDNA/Au electrode from 2.81±0.1 to 7.62±0.2 kΩ and for ssDNA/AunanoME from 2.58±0.1 to 9.95±0.2 kΩ. The results showed that the immobilization and hybridization of DNA on the AunanoME increases effectively the nanobiosensor response compared with the Au bare electrode. In addition, the electrochemical DNA biosensor showed a good selectivity toward the detection of the complementary oligonucleotides of the rfbE gene of E. coli O157. The nanobiosensor response showed a linear dynamic range 1.0×10−13 to 1.0×10−6 mol L−1 with a detection limit of 9.1×10−14 mol L−1 and was able to detect E. coli O157 : H7 real sample corresponding to 102 cells per ml. Our results suggest that, the nanobiosensor is promising for environmental and clinical applications.

Published: June 2016

AbstractTwo hole‐transporting materials (HTMs) based on N,N,N′,N′‐ tetraphenylbenzidine (TPB) and MeO‐triphenylamine (MOTPA) are synthesized. The HTMs offer outstanding thermal stability, film‐forming properties, and hole mobilities. Perovskite solar cells (PSCs) are prepared using either pristine HTM layers or layers doped with cobalt salts. The nondoped PSCs with as‐synthesized HTMs show better performance compared to spiro‐OMeTAD, especially for long‐time stability in ambient air. The power conversion efficiency (PCE) of the cells decreases by only 3 % after 600 h of storage. The nondoped hole‐transport layer (HTL) are hydrophobic, with a contact angle of 94.3° to water. The moisture‐repelling ability of these HTMs are demonstrated by exposing the nondoped PSCs to an atmosphere saturated with water vapor. The PCE of doped PSCs with spiro‐OMeTAD as HTL decreased 53 %, while that of nondoped PSCs with the as‐synthesized HTMs as HTL only decreased 27 % after 15 min. These result thus show a new method to improve the operational stability of PSCs, especially at high humidity levels.
Reproductive effects on freshwater fish exposed to 17α-trenbolone and 17α-estradiol
Authors: Robinson Joseph A. , Staveley Jane P. , Constantine Lisa 
Published: June 2016

Abstract

17α-Trenbolone and 17α-estradiol are principal metabolites in cattle excreta following the administration of Synovex® ONE, which contains trenbolone acetate and estradiol benzoate. As part of the environmental assessment of the use of Synovex® ONE, data were generated to characterize the effects of 17α-trenbolone and 17α-estradiol on the reproduction of freshwater fish. These substances are known endocrine disruptors, so the purpose of testing was not to clarify these properties but to identify concentrations representing population-relevant effects for use in risk characterization. The short-term reproduction assay was conducted with 17α-trenbolone using the fathead minnow (Pimephales promelas) and the medaka (Oryzias latipes) and with 17α-estradiol using the fathead minnow. Adverse effects on the population-relevant endpoints of survival and fecundity were used to establish the no-observed-effect concentration (NOEC) and the lowest-observed-effect concentration (LOEC) for each study. For 17α-trenbolone, adverse effects on fecundity of the fathead minnow occurred at 120 ng/L; this was the LOEC, and the NOEC was 35 ng/L. 17β-Trenbolone did not adversely affect survival and fecundity of medaka at the concentrations tested, resulting in a NOEC of 110 ng/L and a LOEC of &gt;110 ng/L. 17α-Estradiol did not adversely impact survival and fecundity of the fathead minnow at the concentrations tested, resulting in a NOEC and LOEC of 250 ng/L and &gt;250 ng/L, respectively.

Reduced‐order modeling for nonlocal diffusion problems
Authors: Witman David R. , Gunzburger Max , Peterson Janet 
Published: June 2016

SummaryIn several settings, diffusive behavior is observed to not follow the rate of spread predicted by parabolic partial differential equations (PDEs) such as the heat equation. Such behaviors, often referred to as anomalous diffusion, can be modeled using nonlocal equations for which points at a finite distance apart can interact. An example of such models is provided by fractional derivative equations. Because of the nonlocal interactions, discretized nonlocal systems have less sparsity, often significantly less, compared with corresponding discretized PDE systems. As such, the need for reduced‐order surrogates that can be used to cheaply determine approximate solutions is much more acute for nonlocal models compared with that for PDEs. In this paper, we consider the construction, application, and testing of proper orthogonal decomposition (POD) reduced models for an integral equation model for nonlocal diffusion. For certain modeling parameters, the model we consider allows for discontinuous solutions and includes fractional Laplacian kernels as a special case. Preliminary computational results illustrate the potential of using POD to obtain accurate approximations of solutions of nonlocal diffusion equations at much lower costs compared with, for example, standard finite element methods.

AbstractDue to increasing reports on poor‐quality palm oil in the market, there has been a continual decrease in demand and revenue cum product rejection of palm oil sold in Jos, Nigeria. Hence, the significance of this work aims to moderate the microbial and physical qualities of crude palm oil sold in different major markets in order to increase revenue through quality control and quality assurance protocols. The intent is to create awareness among government monitoring agencies, buyers (exporters and importers), and to promote standard processing procedures among manufacturers. The study was carried out to ascertain the levels of mold contamination and physicochemical properties of crude palm oil sold in Jos and its environ. A total of 90 samples were collected in sterile containers. Molds were isolated and identified using standard identification procedures. The physicochemical properties: free fatty acids (FFA), peroxide value (PV), iodine value (IV), moisture content (MC), and impurity level were determined. The assessment of mold isolated from the study sites recognized some life‐threatening genera capable of producing carcinogenic toxins. Candida sp. (51%) had the highest percentage of occurrence followed by Aspergillus sp. (45%) while Fusarium sp. (3%) was the least occurring mold. The mean mold count for all the palm oil samples ranges from 3.18 × 104 (cfu/mL)–4.56 × 104 (cfu/mL). Physicochemical findings showed that the average FFA (3.43–6.88%), PV (6.96–13.63 mEq/kg), IV (39.7–67.5 wijs), and MC (0.44–0.72%) values were within the SON acceptable limit, except the impurity level (0.28–0.44%) which was higher than the acceptable SON range in all the sites. There was a significant difference (P ≤ 0.05) in the mold and physicochemical properties of crude palm oil in almost all the samples analyzed when compared to both local and international permissible limits of the tested parameters recommended for edible palm oil. There was compliance between the permissible limits (local and international) of the physicochemical values of the parameters we tested for in the edible palm oil except the impurity level, while the mold count did not meet (was higher) with the required permissible limit of the SON mold count.
Parameter Estimation for a Proton Exchange Membrane Fuel Cell Model Using GRG Technique
Authors: Geem Z. W. , Noh J.‐S. 
Published: June 2016

AbstractThe parameter estimation of the proton exchange membrane fuel cell (PEMFC) model is important to accurately present the relationship between voltage versus current. Regarding this problem, the difference between observed voltage and model‐calibrated voltage, which composed of cell reversible voltage, activation voltage drop, ohmic loss, and concentration voltage drop, should be minimized. So far, various optimization algorithms have tackled this problem. However, there is still a way to improve the solution quality using another technique, and in order to fairly compare the solution qualities among the techniques, more information is required which has been so far missed. Thus, this study proposed generalized reduced gradient (GRG) technique which obtained good results. When compared with two variants of harmony search and two variants of particle swarm optimization, GRG could find much better results in terms of mean square error (MSE). Also, this study provided full problem formulation and numerical dataset, which was scattered in literature and not clearly provided in previous literature. Hopefully, this study invites more researchers to replicate this bench‐mark problem of the PEMFC parameter estimation and to tackle it using their own techniques in the future.
Microglia engulf viable newborn cells in the epileptic dentate gyrus
Authors: Luo Cong , Koyama Ryuta , Ikegaya Yuji 
Published: June 2016

Microglia, which are the brain's resident immune cells, engulf dead neural progenitor cells during adult neurogenesis in the subgranular zone (SGZ) of the dentate gyrus (DG). The number of newborn cells in the SGZ increases significantly after status epilepticus (SE), but whether and how microglia regulate the number of newborn cells after SE remain unclear. Here, we show that microglia rapidly eliminate newborn cells after SE by primary phagocytosis, a process by which viable cells are engulfed, thereby regulating the number of newborn cells that are incorporated into the DG. The number of newborn cells in the DG was increased at 5 days after SE in the adult mouse brain but rapidly decreased to the control levels within a week. During this period, microglia in the DG were highly active and engulfed newborn cells. We found that the majority of engulfed newborn cells were caspase‐negative viable cells. Finally, inactivation of microglia with minocycline maintained the increase in the number of newborn cells after SE. Furthermore, minocycline treatment after SE induced the emergence of hilar ectopic granule cells. Thus, our findings suggest that microglia may contribute to homeostasis of the dentate neurogenic niche by eliminating excess newborn cells after SE via primary phagocytosis. GLIA 2016;64:1508–1517
Trichosporon: another yeast‐like organism responsible for immune reconstitution inflammatory syndrome in patients with hematological malignancy

Published: June 2016

AbstractTrichosporon has recently emerged as a life‐threatening opportunistic fungal pathogen, notably in patients with hematological malignancy. Fungemia, sometimes associated with cutaneous lesions and/or pneumonitis, is the major clinical form. Here, we report two cases of patients suffering from acute leukaemia who developed hepatic and/or splenic lesions apart from Trichosporon positive blood cultures. The appearance of hepatic and splenic lesions following the recovery from neutropenia is highly suggestive of a chronic disseminated infection, now considered as an immune reconstitution inflammatory syndrome. Treatment with corticosteroid therapy led to clinical improvement in both cases. Copyright © 2016 John Wiley & Sons, Ltd.
Tests of Predictive Ability for Vector Autoregressions Used for Conditional Forecasting
Authors: Clark Todd E. , McCracken Michael W. 
Published: June 2016

SummaryMany forecasts are conditional in nature. For example, a number of central banks routinely report forecasts conditional on particular paths of policy instruments. Even though conditional forecasting is common, there has been little work on methods for evaluating conditional forecasts. This paper provides analytical, Monte Carlo and empirical evidence on tests of predictive ability for conditional forecasts from estimated models. In the empirical analysis, we examine conditional forecasts obtained with a VAR in the variables included in the DSGE model of Smets and Wouters (American Economic Review 2007; 97: 586–606). Throughout the analysis, we focus on tests of bias, efficiency and equal accuracy applied to conditional forecasts from VAR models. Copyright © 2016 John Wiley & Sons, Ltd.

Published: June 2016

AbstractThis systematic review and meta‐analysis evaluated the influence of biological implant surface coatings on periimplant bone formation in comparison to an uncoated titanium reference surface in experimental large animal models. The analysis was structured according to the PRISMA criteriae. Of the1077 studies, 30 studies met the inclusion criteriae. Nineteen studies examined the bone implant contact (BIC) and were included in the meta‐analysis. Overall, the mean increase in BIC for the test surfaces compared to the reference surfaces was 3.7 percentage points (pp) (95% CI −3.9–11.2, p = 0.339). Analyzing the increase in BIC for specific coated surfaces in comparison to uncoated reference surfaces, inorganic surface coatings showed a significant mean increase in BIC of 14.7 pp (95% CI 10.6–18.9, p < 0.01), extracellular matrix (ECM) surface coatings showed an increase of 10.0 pp (95% CI 4.4–15.6, p < 0.001), and peptide coatings showed a statistical trend with 7.1 pp BIC increase (95% CI −0.8–15.0, p = 0.08). In this review, no statistically significant difference could be found for growth factor surface coatings (observed difference −3.3 pp, 95% CI −16.5–9.9, p = 0.6). All analyses are exploratory in nature. The results show a statistically significant effect of inorganic and ECM coatings on periimplant bone formation. © 2016 Wiley Periodicals, Inc.
