Published: August 2019

AbstractAlthough being less competitive energy density‐wise, Na‐ion batteries are serious alternatives to Li‐ion ones for applications where cost and sustainability dominate. O3‐type sodium layered oxides could partially overcome the energy limitation, but their practical use is plagued by a reaction process that enlists numerous phase changes and volume variations while additionally being moisture sensitive. Here, it is shown that the double substitution of Ti for Mn and Cu for Ni in O3‐NaNi0.5−yCuyMn0.5− zTizO2 can alleviate most of these issues. Among this series, electrodes with specific compositions are identified that can reversibly release and uptake ≈0.9 sodium per formula unit via a smooth voltage‐composition profile enlisting minor lattice volume changes upon cycling as opposed to ΔV/V≈23% in the parent NaNi0.5Mn0.5O2 while showing a greater resistance against moisture. The positive attributes of substitution are rationalized by structure considerations supported by density functional theory (DFT) calculations. Electrodes with sustained capacities of ≈180 mAh g−1 are successfully implemented into 18 650 Na‐ion cells having greater performances, energy density‐wise (≈250 Wh L−1), than today's Na3V2(PO4)2F3/HC Na‐ion technology which excels in rate capabilities. These results constitute a step forward in increasing the practicality of Na‐ion technology with additional opportunities for applications in which energy density prevails over rate capability.

AbstractArthrogryposis multiplex congenita (AMC) can be a perplexing diagnosis that consists of limited range of motion (ROM) and decreased muscle strength in multiple joints. The person with AMC often possesses a certain tenacity and “spunk” that assists them with adjusting and adapting to the realities of daily life. The rehabilitation process assists the individual with AMC in achieving and maintaining the maximal active and passive range of motion and strength in order to participate in activities of daily living (ADL) throughout the developmental stages. The result of this life‐long process is greatly impacted by collaboration among the multidisciplinary teams. Ultimately, rehabilitation should focus on three levels of treatment: (a) body structure, (b) activity, and (c) participation. This article describes rehabilitation across the lifespan—focusing on the therapeutic needs in the infant, toddler, school age and teenage/adult years—while also highlighting opportunities for improvement.

Authors: Leonardi Mathew , Condous George 
Published: August 2019

AbstractWe believe the uterosacral ligaments (USLs) are an essential key to resolving the dilemma of diagnosing endometriosis non‐invasively. This editorial will utilise laparoscopic and ultrasonographic figures and videos, along with written descriptive techniques, to educate clinicians, sonographers, sonologists and radiologists on normal and abnormal USLs to improve knowledge and skill in scanning patients with possible endometriosis.

Published: August 2019

BackgroundPortal venous gas (PVG) and pneumatosis intestinalis (PI) are rare pathologic findings, and a delayed appearance of portal vein thrombosis (PVT) in such patients is extremely rare.Case PresentationA 51‐year‐old man complaining of epigastric pain was referred to our hospital. Computed tomography (CT) at admission revealed massive PVG and extensive PI, but no PVT. Emergency laparotomy was carried out, but bowel resection was unnecessary. On follow‐up CT on postoperative day 5, thrombosis was noted in the portal venous system, and anticoagulant was started immediately. This patient was discharged and continued to take the anticoagulant. Seven months after discharge, PVT had disappeared on CT without any thromboembolic complications.ConclusionIf acute PVT is detected, anticoagulant is needed to prevent bowel ischemia and/or portal hypertension due to the growth of the thrombus. Clinicians should be aware of the potential for such a complication, and make their best efforts to exclude this entity using CT or sonography.

ObjectiveTo evaluate the effect of a decrease in blood pressure (BP) fulfilling the diagnostic criteria for orthostatic hypotension (OH) on performance in each domain of cognitive function in patients with type 2 diabetes mellitus using a cross‐sectional and within‐group design.MethodsSubjects were individuals without dementia and with type 2 diabetes mellitus, including 107 individuals without OH and 94 with OH (DMOH); 95 control participants were also included. BP was assessed in both the supine and standing positions. A detailed neuropsychological assessment was made in each posture for all subjects.ResultsThere were statistically significant differences between the patients without OH and the DMOH group with regard to some cognitive measures while supine. Standing posture exacerbated and broadened cognitive deficits in the DMOH group for all measures in the different domains of cognition including executive functioning, memory, visuospatial skills, information processing speed, and attention. When group‐specific supine scores were used as baseline anchors, both the patients without OH and the DMOH group showed cognitive changes when transitioning from a supine to a standing, upright position, with the DMOH group exhibiting a wider range of neuropsychological deficits in memory, visuospatial skills, executive function, and sustained attention, as well as significant changes in information processing speed.InterpretationThese data demonstrate that type 2 diabetes mellitus patients with OH had transient, posture‐mediated cognitive deficits in excess of those found in diabetes mellitus without OH. Understanding the effects of OH on cognition due to autonomic failure is important, particularly as clinical assessments and neuroimaging collect data only in the seated or supine positions.

PremiseRecent habitat fragmentation is posing a risk to the wavy‐leaved smokebush, Conospermum undulatum (Proteaceae), a rare plant species endemic to southwestern Western Australia. Microsatellite markers are required to characterize the genetic diversity and structure of the species for conservation purposes and to facilitate ecological studies.Methods and ResultsIllumina MiSeq high‐throughput sequencing was used to develop 20 novel microsatellite markers for C. undulatum. Polymorphism at each locus was assessed using 72 individuals from three natural populations. Nineteen markers were polymorphic, with the number of alleles per locus ranging from two to 21, and observed and expected heterozygosity ranging from 0.000 to 1.000 and 0.117 to 0.919, respectively. All markers successfully amplified in three congeneric species (C. stoechadis, C. canaliculatum and C. triplinervium).ConclusionsThe microsatellite markers will be useful for revealing patterns of genetic diversity, dispersal dynamics, and hybridization events for C. undulatum to inform future conservation efforts.

Published: August 2019

AbstractIn this work, we developed a one‐pot synthesis of guanidine directly from isothiocyanate using DIB (diacetoxyiodobenzene) as a desulfurizing agent under micellar conditions in water. Our optimization study revealed that the use of 1 % TPGS‐750‐M as a surfactant with NaOH as an additive base at room temperature can convert a variety of isothiocyanates and amines into corresponding guanidines in excellent yields (69–95 %). This synthetic process in water can be applied to prepare guanidine at gram‐scale quantity. Our aqueous micellar medium also demonstrated high reusability as the reaction can be performed for several cycles without losing its efficiency. The reaction is metal‐free, utilizes water as solvent and practical (room temperature and open flask).
A two‐stage searching method for continuous time‐delay systems identification
Authors: Bai Meng , Li Minhua 
Published: August 2019

AbstractThis paper presents a novel method to estimate the unknown parameters of continuous‐time systems with time delay. In the proposed method, the time delay and plant parameters are estimated separately. To estimate the time delay, a one‐dimensional searching method with variable step size is proposed to improve computational efficiency. The searching method consists of two stages: the coarse stage and the refined searching stage. To analyze the convergence of the searching method, the concept of significant interval is proposed. By defining the significant interval, a sufficient condition for global convergence of the searching method is provided. Based on the two‐stage searching method, a novel identification algorithm is developed in which the simplified refined instrumental variable for continuous‐time models algorithm is used to estimate the plant parameters. Simulation results demonstrate that the proposed identification method can estimate the unknown parameters of continuous‐time system with time delay efficiently. The estimation results under different noisy conditions verify the reliability and robustness of the proposed method. The applicability of the developed identification method is demonstrated by a practical example.
Numerical methods for the minimal non‐negative solution of the non‐symmetric coupled algebraic Riccati equation
Authors: Zhang Juan , Tan Fangyuan 
Published: August 2019

AbstractIn this paper, base on the theory of the non‐symmetric algebraic Riccati equation and the coupled Riccati equation, we give the general form of the non‐symmetric coupled algebraic Riccati equation (NCARE). In order to effectively solve the minimal non‐negative solution of the NCARE, two numerical iteration methods are improved: inexact Newton method (INewton) and alternate linear implicit method (ALI). Further, we give the convergence theory of the two iteration methods. Finally, we offer numerical examples to show the effectiveness of the derived methods.

Children with autism spectrum disorder (ASD) exhibit significant difficulties with emotion regulation and reactivity, which may be linked to underlying psychophysiology. The present study examined associations between autonomic nervous system activity and individual differences in externalizing behavior problems in children with ASD. A multisystem approach was adopted to consider the interplay between markers of sympathetic (electrodermal reactivity—EDA‐R) and parasympathetic reactivity (respiratory sinus arrhythmia reactivity—RSA‐R) in relation to behavioral challenges. Fifty‐two children with ASD ages 6–10 years contributed complete psychophysiological data. Measures of EDA‐R and RSA‐R (RSA withdrawal) were obtained in response to a laboratory challenge task and parents reported on child externalizing behavior problems using a standardized questionnaire and a structured clinical interview. An equifinality model was supported, with two distinct psychophysiological pathways linked to heightened externalizing behavior problems. Greater RSA‐R was associated with more externalizing problems in the context of higher levels of EDA‐R, and lower EDA‐R was associated with increased externalizing problems at lower levels of RSA‐R. Findings underscore the importance of considering the role of psychophysiology in the unfolding of comorbid externalizing problems in children with ASD. Potential implications for tailoring coregulatory supports are discussed. Autism Res 2019, 12: 1805–1816. © 2019 International Society for Autism Research, Wiley Periodicals, Inc.Lay SummaryChildren with autism spectrum disorder (ASD) exhibit elevated rates of challenging behavior. This study identified specific psychophysiological profiles (low sympathetic‐low parasympathetic reactivity, and high sympathetic‐high parasympathetic reactivity) that may place these children at greater risk for behavior problems. Findings have implications for better understanding behavioral challenges in children with ASD, and for tailoring supports to address underlying psychophysiology.
Stress and support: The dual role of the migrant community in the acculturation of Korean migrant families in Australia
Authors: Kim Hyo‐Jung , Khawaja Nigar G. , Eivers Areana 
Published: August 2019

AbstractDespite recent exploration of diverse acculturation experiences, there is still limited understanding of the specific acculturation features of the migrant experience. To address this gap, the current study aimed to explore subjective acculturation experiences of Korean migrant families by focusing on the contexts of home country, migrant community, and marital relationship. Twenty‐three married South Korean migrants with young children participated in four focus groups. Thematic analysis was used to identify major themes from the discussion. Participants reported that, contrary to a stressful life in Korea, they developed premigration expectations regarding a relaxed life in Australia. However, once the participants became involved in the Korean migrant community in Australia, their expectations were mismatched by recreating their previous stressful lives in the new country. The Korean migrant community was helpful in participants' adaptation but also unhelpful in handling acculturation issues of mismatched expectations and parental stress. The study also found that although some postmigration marital conflicts arose, marital communication in the relationship may have a protective role in solving migrants' difficulties. These findings highlight the need for enhancing the traditional acculturation framework with other theoretical frameworks to capture both general and specific acculturation features of the migrant experience.

AbstractPhotocatalytic oxidation of alcohols with high selectivity is a promising approach for the synthesis of organic compounds under mild conditions and for solar energy conversion. In this work, we report on the highly selective anaerobic photooxidation of alcohols to carbonyl compounds with coupled H2 production over Pt‐loaded Fe‐doped SrTiO3 under visible light. Representatively, an optimized apparent quantum efficiency of 13.2 % at 420 nm was obtained for benzyl alcohol oxidation. X‐ray absorption fine structure and in situ diffuse reflectance IR spectroscopy revealed that the surface oxygen vacancies and the fine‐tuned valence band edge position induced by Fe doping not only contributed to the activation of α‐C−H bonds in alcohols, but also avoided the over‐oxidation of the obtained carbonyl compounds.

AbstractCholinergic transmission shapes the maturation of glutamatergic circuits, yet the developmental sources of acetylcholine have not been systematically explored. Here, we have used Cre‐recombinase‐mediated genetic labeling to identify and map both mature and developing CNS neurons that express choline acetyltransferase (ChAT). Correction of a significant problem with a widely used ChatCre transgenic line ensures that this map does not contain expression artifacts. ChatCre marks all known cholinergic systems in the adult brain, but also identifies several brain areas not usually regarded as cholinergic, including specific thalamic and hypothalamic neurons, the subiculum, the lateral parabrachial nucleus, the cuneate/gracilis nuclei, and the pontocerebellar system. This ChatCre fate map suggests transient developmental expression of a cholinergic phenotype in areas important for cognition, motor control, and respiration. We therefore examined expression of ChAT and the vesicular acetylcholine transporter in the embryonic and early postnatal brain to determine the developmental timing of this transient cholinergic phenotype, and found that it mirrored the establishment of relevant glutamatergic projection pathways. We then used an intersectional genetic strategy combining ChatCre with Vglut2Flp to show that these neurons adopt a glutamatergic fate in the adult brain. The transient cholinergic phenotype of these glutamatergic neurons suggests a homosynaptic source of acetylcholine for the maturation of developing glutamatergic synapses. These findings thus define critical windows during which specific glutamatergic circuits may be vulnerable to disruption by nicotine in utero, and suggest new mechanisms for pediatric disorders associated with maternal smoking, such as sudden infant death syndrome.

Published: August 2019

AbstractThe key role of colour in ergonomics has been emphasized by a number of researchers and design professionals. Although several research studies have been published regarding the use of colour in ergonomics, there are still some areas that need to be considered. The issue of deciding a “colour of the year” is an example, which represents a new challenge for researchers in the field of ergonomics. This is of particular interest considering the fact that the nature of research on the selection of a “colour of the year” is generally based on user experience. This paper argues that ergonomics should play a more prominent role in this field to ensure better user experience and performance. This paper highlights specific areas that need further study and development.

Published: August 2019

SummaryGPUs are very powerful computing accelerators that are often employed in single‐device configuration. However, there is a steadily growing interest in using multiple GPUs in a concurrent way both to overcome the memory limitations of the single device and to further reduce execution times. Until recently, communication among GPUs had been carried out mainly by using networking technologies originally devised for standard CPUs with the CPU playing an active role in the communication. However, new alternatives start to be available in which a moderate number of GPUs are directly connected each other by means of proprietary technologies. We present the results of a set of experiments aimed at assessing the performance of some of these hardware/software platforms using a particularly challenging application as a benchmark. We release its source code to facilitate people interested in reproducing or extending our results.

Published: August 2019

SummaryAiming at further improving the energy efficiency of system while meeting the data rate requirement of the users, in this paper, a network energy efficiency optimization problem by jointly optimizing the resource allocation of macrocells and small cells is formulated and proven to be an NP‐hard problem, which cannot be worked out by direct methods in polynomial time. Considering the effectiveness of the modified particle swarm optimization (MPSO) algorithm, an MPSO‐based resource allocation and cell association algorithm is employed to solve the proposed joint optimization problem where the frequency resource partitioning of the macrocells, the transmission power, and the cell‐association bias of the small cells are jointly optimized. During the implementation of the optimization algorithm, the cell association alters with the transmission power and cell‐association bias adjustment, and the small cells where there are no active users associating with them will be turned off. The data rate requirement of the users is an indispensable metric in the communication system. Taking no account of the data rate requirement of the users, the frequency resource partitioning and cell association alteration will deteriorate the data rate of a few of users. Under such circumstances, we take the users' data rate requirement as a constraint of the joint optimization problem. The system level simulation results show that, by jointly optimizing the resource allocation of macrocells and small cells while guaranteeing the users' data rate requirement, the energy efficiency and system throughput can be further improved, and energy consumption can be further reduced.
