Published: November 2018

A group of small bivalves inhabiting Indian brackish-water estuaries and lagoons (known locally as backwaters), variously assigned to Corbula, Cuspidaria, and Sphenia, are reviewed and, based on shell characters, shown to be congeneric. Molecular (COI) and morphological data indicate that this group belongs to the family Myidae. Furthermore, the combined data suggest that these Indian myids are a sister taxon of the genus Sphenia. The Indian material studied herein exhibits a functional morphology typical of infaunal bivalves, whereas typical Sphenia are nestling and epibyssate. A new genus, Indosphenia, is thus erected for the Indian group and includes five species, one of which is named in this study.
Indospheniakayalum Oliver, Hallan &amp; Jayachandran, gen. et sp. n. is described from the Cochin Backwater on the western coast of India. Cuneocorbulacochinensis (Preston, 1916) is transferred to Indosphenia. Additionally, the west coast taxa I.abbreviata (Preston, 1907), I.abbreviatachilkaensis (Preston, 1911) and I.sowerbyi (EA Smith, 1893) are recognised herein. Corbulaalcocki Preston, 1907, Corbulagracilis Preston, 1907, Corbulacalcaria Preston, 1907 and Corbulapfefferi Preston, 1907 are placed in synonymy with I.abbreviata, and Cuspidariaannandalei Preston, 1915 is synonymised with I.abbreviatachilkaensis.

Abstract

Background:
People with multiple sclerosis (MS) are at increased risk for cognitive impairment, mental health concerns, and psychosocial issues, which can negatively affect disease outcomes and quality of life. Current MS care guidelines recommend integrated interdisciplinary services to address these concerns; however, issues can be overlooked during routine care. To date, there is inadequate research on how often these issues are identified and addressed during routine MS care.

Methods:
One hundred medical records were randomly selected and reviewed (55 relapsing-remitting MS, 17 secondary progressive MS, 8 primary progressive MS, and 20 other or subtype not indicated). All visits to, and contacts with (ie, telephone, e-mail), an MS clinic over 1 year were included in the analysis to determine the proportion of patients presenting with cognitive, mental health, and psychosocial concerns and the proportion of patients offered associated services.

Results:
Of the 25 patients with at least one identified concern, treatment recommendations occurred for 13 (52%). Rates of identification of cognitive, mental health, and psychosocial concerns in standard clinical practice were significantly lower than the identified prevalence in epidemiologic studies. Demographic factors had no bearing on who was offered treatment. Patients with concerns access MS clinic services more often than those without.

Conclusions:
Discrepancies between reported and expected frequencies may be due to overreliance on patient self-disclosure and concerns by the health care team that inadequate resources are available to address issues. An interdisciplinary team model may help address these issues.

Background. Metagenomics studies have reported on the complexity of microbiomes associated with seagrass and can provide critical insights into the sustainable use and conservation of seagrasses. Recent conservation activities in Kenya focused mainly on coral reefs and mangrove forests with little direct action taken to conserve seagrass meadows. Pollution, over-exploitation of marine resources and minimal efforts towards enforcement of conservation laws of marine environments, have caused degradation and defoliation of seagrass habitats. Little is known about the microbes associated with seagrass species in Kenya and this study aimed to characterize the genetic diversity of the microbiomes of two prominent seagrass species, Enhalus acoroides and Thallasodendron ciliatum, which are the most commonly occurring species.
Methods. Replicate microbiome samples were collected from leaves, roots, sediment and water columns associated with the two seagrass species from two sites on the Kenyan coast. The microbial communities of the samples were characterized and compared using 16S ribosomal RNA gene PCR and sequencing. Microbiome features including diversity and taxonomic composition were used to compare within and between sample types and sites.
Results. Leaf samples from both E. acoroides and T. ciliatum had significantly different microbial communities comparted to root and sediment samples, revealing a diversity gradient with lowest diversity in water samples and highest in sediment. There were no significant variation in seagrass microbial composition associated with leaf and rhizosphere microbiomes of either E. acoroides or T. ciliatum. However, we did see a difference between water samples associated with each seagrass species.
Discussion. This study of the microbiomes associated with the sediments, roots, leaves and surrounding water of E. acoroides and T. ciliatum, included a limited number of samples from a small geographic area, providing a valuable first assessment of the microbial diversity of seagrass beds on the Kenyan coast. We found no significant differences between the plant-associated bacterial communities of the two-seagrass species investigated. Significant differences however, were observed amongst leaf-, root-, sediment- and water-associated bacterial communities. This work will contribute to understanding the dynamic environment of seagrass beds and will contribute to helping conserving and re-establishing seagrass beds degraded by due to anthropogenic activities.
Repeatedly adopting power postures does not affect hormonal correlates of dominance and affiliative behavior
Authors: Metzler Hannah , Grèzes Julie 
Published: November 2018

Background. Adopting expansive versus constrictive postures related to high versus low levels of social power has been suggested to induce changes in testosterone and cortisol levels, and thereby to mimic hormonal correlates of dominance behavior. However, these findings have been challenged by several non-replications recently. Although there is thus more evidence against than for such posture effects on hormones, the question remains as to whether repeatedly holding postures over time and/or assessing hormonal responses at different time points would yield different outcomes. The current study assesses these methodological characteristics as possible reasons for previous null-findings. By testing effects of repeated but short posture manipulations in a social context while using a cover-story, it further fulfills the conditions previously raised as potentially necessary for the effects to occur.
Methods. 82 male participants repeatedly adopted an expansive or constrictive posture for 2 minutes in between blocks of a task that consisted in categorizing faces based on first impressions. Saliva samples were taken at two different time points in a time window in which hormonal responses to stress, competition and other manipulations are known to be strongest.
Results. Neither testosterone and cortisol levels linked to dominance behaviors, nor progesterone levels related to affiliative tendencies, changed from before to after adopting expansive or constrictive postures. The present results establish that even repeated power posing in a context where social stimuli are task-relevant does not elicit changes in hormone levels.

Aging impairs the activation of stress signaling pathways (SSPs), preventing the induction of longevity mechanisms late in life. Here, we show that the antibiotic minocycline increases lifespan and reduces protein aggregation even in old, SSP-deficient Caenorhabditis elegans by targeting cytoplasmic ribosomes, preferentially attenuating translation of highly translated mRNAs. In contrast to most other longevity paradigms, minocycline inhibits rather than activates all major SSPs and extends lifespan in mutants deficient in the activation of SSPs, lysosomal or autophagic pathways. We propose that minocycline lowers the concentration of newly synthesized aggregation-prone proteins, resulting in a relative increase in protein-folding capacity without the necessity to induce protein-folding pathways. Our study suggests that in old individuals with incapacitated SSPs or autophagic pathways, pharmacological attenuation of cytoplasmic translation is a promising strategy to reduce protein aggregation. Altogether, it provides a geroprotecive mechanism for the many beneficial effects of tetracyclines in models of neurodegenerative disease.Editorial note: This article has been through an editorial process in which the authors decide how to respond to the issues raised during peer review.

Anthropometric prediction of DXA-measured body composition in female team handball players
Authors: Cavedon Valentina , Zancanaro Carlo , Milanese Chiara 
Published: November 2018

Background
The relevance of body composition (BC) to performance in sport has long been appreciated with special concern on the total and regional proportion of fat and muscle. Dual-energy X-ray absorptiometry (DXA) is able to accurately measure BC, but it may not be easily available in practice; anthropometry has long been used as a simple and inexpensive field method to objectively assess BC. The aim of this study was twofold: first, to develop and validate a sport-specific anthropometric predictive equation for total body fat mass (FM) and lean mass components in female handball players to be used in the sport setting; second, to cross-validate in female team handball players several independently developed, predictive equations for BC in female athletes.

Methods
A total of 85 female team handball players (30 wings, 31 backs, 14 pivots, 10 goalkeepers) of different competitive levels underwent anthropometry and a whole-body DXA scan. Multiple linear regression analysis was used to develop predictive equations in a derivation sample (n = 60) of randomly selected players using demographic and anthropometric variables. The developed equations were used to predict DXA outcomes in an independent validation sample (n = 25).

Results
Statistically significant (P < 0.001) models were developed for total body FM (adjusted R2 = 0.943, standard error of the estimate, SEE = 1,379 g), percentage FM (adjusted R2 = 0.877, SEE = 2.00%), fat-free soft tissue mass (FFSTM) (adjusted R2 = 0.834, SEE = 2,412 g), fat-free mass (FFSTM + bone mineral content; adjusted R2 = 0.829, SEE = 2,579 g). All models were robust to collinearity. Each developed equation was successfully validated in the remaining 25 players using correlation analysis, mean signed difference, t-test, and Bland–Altman plot. The whole dataset of team handball players (n = 85) was used to cross-validate several predictive equations independently developed by others in female athletes. Equations significantly (P < 0.001 for all; t-test) over- or underestimated the corresponding DXA measurements.

Discussion
It is concluded that in team female handball players the anthropometric equations presented herein are able to estimate body fat and FFSTM with accuracy. Several BC predictive anthropometric equations developed in different female athletic populations revealed inaccurate when tested in team handball players. These results should be of use for coaches, physical trainers, and nutritionists when evaluating the physical status of female team handball players.
Decentralized robust adaptive neural dynamic surface control for multi‐machine excitation systems with static var compensator
Authors: Zhang Xiuyu , Wang Shuran , Zhu Guoqiang , Ma Jia , Li Xiaoming , Chen Xinkai 
Published: November 2018

SummaryFocusing on solving the control problem of the multimachine excitation systems with static var compensator (SVC), this paper proposes a decentralized neural adaptive dynamic surface control (DNADSC) scheme, where the radial basis function neural networks are used to approximate the unknown nonlinear dynamics of the subsystems and compensate the unknown nonlinear interactions. The main advantages of the proposed DNADSC scheme are summarized as follows: (1) the strong nonlinearities and complexities are mitigated when the SVC equipment are introduced to the multimachine excitation systems and the explosion of complexity problem of the backstepping method is overcome by combining the dynamic surface control method with neural networks (NNs) approximators; 2) the tracking error of the power angle can be kept in the prespecified performance curve by introducing the error transformed function; (3) instead of estimating the weighted vector itself, the norm of the weighted vector of the NNs are estimated, leading to the reduction of the computational burden. It is proved that all the signals in the multimachine excitation system with SVC are semiglobally uniformly ultimately bounded.
Adaptive state‐feedback control with sensor failure compensation for asymptotic output tracking
Authors: Song Ge , Tao Gang 
Published: November 2018

SummaryThis paper addresses a new adaptive output tracking problem in the presence of uncertain plant dynamics and uncertain sensor failures. A new unified nominal state‐feedback control law is developed to deal with various sensor failures, which is directly constructed by state sensor outputs. Such a new state‐feedback compensation control law is able to ensure the desired plant‐model matching properties under different failure patterns. Based on the nominal compensation control design, a new adaptive compensation control scheme is proposed, which guarantees closed‐loop signal boundedness and asymptotic output tracking. The new adaptive compensation scheme not only expands the sensor failures types that the system could tolerate but also avoids some signal processing procedures that the traditional fault‐tolerant control techniques are forced to encounter. A complete stability analysis and a representative simulation study are conducted to evaluate the effectiveness of the proposed adaptive compensation control scheme.
Experimental and Theoretical Insights into the Bioinspired Formation of Disordered Ba‐Calcite

Published: November 2018

AbstractCalcite has the ability to host large amounts of intracrystalline inclusions, a phenomenon that is known to be the case in biominerals and has been demonstrated in bioinspired synthetic systems. In this study, barium ion is focused on as the inclusion. Highly substituted Ba‐calcite possesses disordered carbonate orientations, characteristic of symmetry. It is shown that calcite experiences an order–disorder transition, in which the carbonate groups undergo progressive loss of their rotational order with increasing amounts of incorporated Ba, and reach complete rotational disorder for a critical amount of Ba. This transition is characterized and a theoretical model justifying the influence of Ba is proposed. Moreover, the disordered Ba‐substituted calcite has been previously identified as a high‐temperature phase or as a highly metastable room‐temperature phase. Those descriptions are challenged by successfully synthesizing it under slow‐rate conditions and by studying its thermal behavior, and it is concluded that the fully disordered Ba‐calcite is stable, whereas the transitional, partially disordered Ba‐calcite phase is metastable.
Carbazole–Dibenzofuran Dyads as Metal‐Free Single‐Component White‐Color Photoemitters
Authors: Tabata Kenichi , Yamada Tetsuya , Kita Hiroshi , Yamamoto Yohei 
Published: November 2018

AbstractWhite‐color light emitters from single organic molecule without heavy metals are valuable for practical applications in organic light‐emitting devices. In this study, carbazole (Cz)–dibenzofuran (DBF) donor–acceptor dyads are designed for white‐color light emitters. Originally, these molecules show photoluminescence (PL) in near ultraviolet region. However, upon successive ultraviolet (UV) irradiation, white‐color PL appears, comprising dual‐color phosphorescence from the amorphous and crystalline state of the dyad. A continuous UV irradiation makes the twisting angle between the Cz and DBF planes flatten through the triplet‐excited state, which proceeds crystallization. Thermal annealing and UV irradiation can switch the blue‐ and white‐color phosphorescences from the dyad. Furthermore, charge injection generates white‐color electroluminescence. The materials with PL color modulation ability by UV‐light irradiation and heating can be applicable as light‐ and thermo‐sensors.

AbstractSodium (Na) metal is a promising alternative to lithium metal as an anode material for the next‐generation energy storage systems due to its high theoretical capacity, low cost, and natural abundance. However, dendritic/mossy Na growth caused by uncontrollable plating/stripping results in serious safe concerns and rapid electrode degradation. This study presents Sn2+ pillared Ti3C2 MXene serving as a stable matrix for high‐performance dendrite‐free Na metal anode. The intercalated Sn2+ between Ti3C2 layers not only induces Na to nucleate and grow within Ti3C2 interlayers, but also endows the Ti3C2 with larger interlayer space to accommodate the deposited Na by taking advantage of the “pillar effect,” contributing to uniform Na deposition. As a result, the pillar‐structured MXene‐based Na metal electrode could enable high current density (up to 10 mA cm−2) along with high areal capacity (up to 5 mAh cm−2) over long‐term cycling (up to 500 cycles). The full cell using MXene‐based Na metal anode exhibits superior electrochemical performance than that using host‐less commercial Na. It is believed that the well‐controlled MXene‐based Na anode not only extends the application scope of MXene, but also provides guidance in designing high‐performance Na metal batteries.

AbstractNanomotors have emerged as promising and versatile nanorobotic tools in a variety of medical, sensing, decontamination, and manufacturing applications due to their unique ability to operate and perform task at small scales. This review focuses on the current progress and future perspectives of hybrid nanomotors based on two power sources, with a special highlight on their distinct advantages, unique propulsion behaviors, adaptive operation, and potential applications. Such incorporation of multiple engines into a single nanoscale vehicle addresses certain limitations of nanomotors based on a single propulsion mode and adds new dimensions for advanced motion management. These attractive capabilities of hybrid nanoscale vehicles are discussed along with the challenges and opportunities when coupling several propulsion modes into a single device. With continuous innovations, it is expected that hybrid nanomotors will have a profound impact upon the field of nanorobotics.
