Solvent‐Switching Gelation and Orange–Red Emission of Ultrasmall Copper Nanoclusters
Authors: Liu Jinhua , Zhang Qiang Matthew , Feng Yong , Zhou Zhengyuan , Shih Kaimin 
Published: November 2015

AbstractBy tuning the Cu⋅⋅⋅Cu and hydrogen‐bonding interactions, the small cluster Cu3L can be selectively synthesized to develop a stable and highly fluorescent material, as confirmed by matrix‐assisted laser desorption ionization–time of flight mass spectroscopy. Further characterizations, including absorbance spectroscopy, XPS, and XRD demonstrate the formation of tiny Cu nanoclusters (NCs). In water, the as‐prepared Cu NCs can exhibit high orange fluorescence via solution evaporation to eliminate hydrogen‐bonding, and in dimethylformamide, a strong orange fluorescent gel is obtained by solvent induction to enhance the Cu⋅⋅⋅Cu and hydrogen‐bonding interactions. More importantly, the Cu NCs in their substantial form exhibit nonlinear optical properties upon two‐photon excitation. These results will shed light on Cu and related cluster applications in two‐photon biological imaging, optical power limiting, and solar energy conversion.
The Dilemma of Supporting Electrolytes for Electroorganic Synthesis: A Case Study on Kolbe Electrolysis
Authors: Stang Carolin , Harnisch Falk 
Published: November 2015

AbstractRemarkably, coulombic efficiency (CE, about 50 % at 1 Farad equivalent), and product composition resulting from aqueous Kolbe electrolysis are independent of reactor temperature and initial pH value. Although numerous studies on Kolbe electrolysis are available, the interrelations of different reaction parameters (e.g., acid concentration, pH, and especially electrolytic conductivity) are not addressed. A systematic analysis based on cyclic voltammetry reveals that solely the electrolytic conductivity impacts the current–voltage behavior. When using supporting electrolytes, not only their concentration, but also the type is decisive. We show that higher concentrations of KNO3 result in reduced CE and thus in significant increase in electric energy demand per converted molecule, whereas Na2SO4 allows improved space–time yields. Pros and cons of adding supporting electrolytes are discussed in a final cost assessment.

AbstractA full‐scale controlled experiment was conducted on an excavated and re‐assembled coastal wetland surface, typical of floristically diverse northwest European saltmarsh. The experiment was undertaken with true‐to‐scale water depths and waves in a large wave flume, in order to assess the impact of storm surge conditions on marsh surface soils, initially with three different plant species and then when this marsh canopy had been mowed. The data presented suggests a high bio‐geomorphological resilience of salt marshes to vertical sediment removal, with less than 0.6 cm average vertical lowering in response to a sequence of simulated storm surge conditions. Both organic matter content and plant species exerted an important influence on both the variability and degree of soil surface stability, with surfaces covered by a flattened canopy of the salt marsh grass Puccinellia experiencing a lower and less variable elevation loss than those characterized by Elymus or Atriplex that exhibited considerable physical damage through stem folding and breakage.

Quantifying the Morphological Print of Bedload Transport
Authors: Recking Alain , Piton Guillaume , Vazquez‐Tarrio Daniel , Parker Gary 
Published: November 2015

AbstractBedload and river morphology interact in a strong feedback manner. Bedload conditions the development of river morphology along different space and time scales; however, by concentrating the flow in preferential paths, a given morphology controls bedload for a given discharge. As bedload is a non‐linear response of shear stress, local morphology is likely to have a strong impact on bedload prediction when the shear stress is averaged over the section, as is usually done.This was investigated by comparing bedload measured in different bed morphologies (step‐pool, plane bed, riffle‐pool, braiding, and sand beds), with bedload measured in narrow flumes in the absence of any bed form, used here as a reference. The initial methodology consisted of fitting a bedload equation to the flume data. Secondly, the morphological signature of each river was studied as the distance to this referent equation.It was concluded that each morphology affects bedload in a different way. For a given average grain shear stress, the larger the river, the larger the deviation from the flume transport. Narrow streams are those morphologies that behave more like flumes; this is particularly true with flat beds, whereas results deviate from flumes to a greater extent in step‐pools. The riffle‐pool's morphology impacts bedload at different levels depending on the degree of bar development, considered here through the ratio D84/D50 which is used as a proxy for the local bed patchiness and morphology. In braiding rivers morphological effects are important but difficult to assess because width is dependent on transport rate. Bed morphology was found to have negligible effects in sand bed rivers where the Shields stress is usually sufficiently high to minimize the non‐linearity effects when hydraulics is averaged over the section.

AbstractObjectivesRecovery of independent ambulation after stroke is a major goal. However, which rehabilitation regimen best benefits each individual is unknown and decisions are currently made on a subjective basis. Predictors of response to specific therapies would guide the type of therapy most appropriate for each patient. Although lesion topography is a strong predictor of upper limb response, walking involves more distributed functions. Earlier studies that assessed the cortico‐spinal tract (CST) were negative, suggesting other structures may be important.Experimental Design: The relationship between lesion topography and response of walking speed to standard rehabilitation was assessed in 50 adult‐onset patients using both volumetric measurement of CST lesion load and voxel‐based lesion–symptom mapping (VLSM) to assess non‐CST structures. Two functional mobility scales, the functional ambulation category (FAC) and the modified rivermead mobility index (MRMI) were also administered. Performance measures were obtained both at entry into the study (3–42 days post‐stroke) and at the end of a 6‐week course of therapy. Baseline score, age, time since stroke onset and white matter hyperintensities score were included as nuisance covariates in regression models.Principal Observations: CST damage independently predicted response to therapy for FAC and MRMI, but not for walk speed. However, using VLSM the latter was predicted by damage to the putamen, insula, external capsule and neighbouring white matter.ConclusionsWalk speed response to rehabilitation was affected by damage involving the putamen and neighbouring structures but not the CST, while the latter had modest but significant impact on everyday functions of general mobility and gait.

Published: November 2015

AbstractMental disorder and trauma experiences are highly prevalent among individuals in custody; however, the impact of posttraumatic stress disorder (PTSD) on functioning is rarely considered. Indigenous Australians are incarcerated at 13 times the rate of nonindigenous Australians and report high levels of trauma exposure and psychological distress. In analysis of the largest systematic study of mental disorder among indigenous Australians in custody (N = 396), we found that the 12‐month prevalence of PTSD was high in both men (12.1%) and women (32.3%). Having PTSD was also associated with high rates of co‐occurring mental disorders (anxiety 31.2%, depression 32.8%, psychosis 24.6%, and substance use, 75.4%), lifetime suicidal ideation (50.1%), and suicide attempts (34.4%). Individuals with PTSD, compared to those without, were more likely to experience other mental disorders, OR = 2.42, 95% CI [1.12, 5.80], p = .022; lifetime suicide thoughts, OR = 2.43, 95% CI [1.34, 4.39], p = .001, and attempts, OR = 2.56, 95% CI [1.33, 4.83], p = .002; and high rates of intoxication at the time of arrest. Despite this, most (58.9%) had not accessed any form of mental health care prior to incarceration. These findings highlight the need to identify and manage PTSD in community and custodial populations.
Bayesian sampling plans for exponential distributions with interval censored samples
Authors: Chen Lee‐Shen , Yang Ming‐Chung , Liang TaChen 
Published: November 2015

ABSTRACTThis article studies the problem of designing Bayesian sampling plans (BSP) with interval censored samples. First, an algorithm for deriving the conventional BSP is proposed. The BSP is shown to possess some monotonicity. Based on the BSP and using the property of monotonicity, a new sampling plan modified by the curtailment procedure is proposed. The resulting curtailed Bayesian sampling plan (CBSP) can reduce the duration time of life test experiment, and it is optimal in the sense that its associated Bayes risk is smaller than the Bayes risk of the BSP if the cost of the duration time of life test experiment is considered. A numerical example to compute the Bayes risks of BSP and CBSP and related quantities is given. Also, a Monte Carlo simulation study is performed to illustrate the performance of the CBSP compared with the BSP. The simulation results demonstrate that our proposed CBSP has better performance because it has smaller risk. The CBSP is recommended. © 2015 Wiley Periodicals, Inc.

Practical Approaches to Definitive Reconstruction of Complex Abdominal Wall Defects
Authors: Latifi Rifat 
Published: November 2015

AbstractWith advances in abdominal surgery and the management of major trauma, complex abdominal wall defects have become the new surgical disease, and the need for abdominal wall reconstruction has increased dramatically. Subsequently, how to reconstruct these large defects has become a new surgical question. While most surgeons use native abdominal wall whenever possible, evidence suggests that synthetic or biologic mesh needs to be added to large ventral hernia repairs. One particular group of patients who exemplify “complex” are those with contaminated wounds, enterocutaneous fistulas, enteroatmospheric fistulas, and/or stoma(s), where synthetic mesh is to be avoided if at all possible. Most recently, biologic mesh has become the new standard in high‐risk patients with contaminated and dirty‐infected wounds. While biologic mesh is the most common tissue engineered used in this field of surgery, level I evidence is needed on its indication and long‐term outcomes. Various techniques for reconstructing the abdominal wall have been described, however the long‐term outcomes for most of these studies, are rarely reported. In this article, I outline current practical approaches to perioperative management and definitive abdominal reconstruction in patients with complex abdominal wall defects, with or without fistulas, as well as those who have lost abdominal domain.

Abstract
Guard cells are indispensable for higher plants because they control gas exchange and water balance to maintain photosynthetic activity. The signaling processes that govern their movement are controlled by several factors, such as abscisic acid (ABA), blue light, pathogen-associated molecular patterns (PAMPs), and carbon dioxide. Herein, we demonstrated that the amino acid glutamate (Glu), a well-known mammalian neurotransmitter, functions as a novel signaling molecule in stomatal closure in both Arabidopsis and fava bean (Vicia faba L.). Pharmacological and electrophysiological analyses provided important clues for the participation of Glu-receptors, Ca2+, and protein phosphorylation during the signaling process. Genetic analyses using Arabidopsis ABA-deficient (aba2-1) and ABA-insensitive (abi1-1 and abi2-1) mutants showed that ABA is not required for Glu signaling. However, loss-of-function of the Arabidopsis gene encoding Slow Anion Channel-Associated
1 (SLAC1) and Calcium-Dependent Protein Kinase 6 (CPK6) impaired the Glu response. Moreover, T-DNA knockout mutations of the Arabidopsis Glu receptor-like gene (GLR), GLR3.5, lost their sensitivity to Glu-dependent stomatal closure. Our results strongly support functional Glu-signaling in stomatal closure and the crucial roles of GLRs in this signaling process.
