AbstractElaborate architectural manipulation of nanohybrids with multi-components into controllable 3D hierarchical structures is of great significance for both fundamental scientific interest and realization of various functionalities, yet remains a great challenge because different materials with distinct physical/chemical properties could hardly be incorporated simultaneously into the synthesis process. Here, we develop a novel one-pot cyanogel-bridged synthetic approach for the generation of 3D flower-like metal/Prussian blue analogue nanohybrids, namely PdCo/Pd-hexacyanocobaltate for the first time. The judicious introduction of polyethylene glycol (PEG) and the formation of cyanogel are prerequisite for the successful fabrication of such fascinating hierarchical nanostructures. Due to the unique 3D hierarchical structure and the synergistic effect between hybrid components, the as-prepared hybrid nanoflowers exhibit a remarkable catalytic activity and durability toward the reduction of Rhodamine B (RhB) by NaBH4. We expect that the obtained hybrid nanoflowers may hold great promises in water remediation field and beyond. Furthermore, the facile synthetic strategy presented here for synthesizing functional hybrid materials can be extendable for the synthesis of various functional hybrid nanomaterials owing to its versatility and feasibility.

Published: August 2016

AbstractLithium-sulphur batteries are under intense research due to the high specific capacity and low cost. However, several problems limit their commercialization. One of them is the insulating nature of sulphur, which necessitates a large amount of conductive agent and binder in the cathode, reducing the effective sulphur load as well as the energy density. Here we introduce a redox mediator, cobaltocene, which acts as an electron transfer agent between the conductive surface and the polysulphides in the electrolyte. We confirmed that cobaltocene could effectively convert polysulphides to Li2S using scanning electron microscope, X-ray absorption near-edge structure and in-situ X-ray diffraction studies. This redox mediator enabled excellent electrochemical performance in a cathode with ultra-high sulphur content (80 wt%). It delivered 400 mAh g−1cathode capacity after 50 cycles, which is equivalent to 800 mAh g−1S in a typical cathode with 50 wt% sulphur. Furthermore, the volumetric capacity was also dramatically improved.

Published: August 2016

AbstractWe suggest and demonstrate the concept and design of sectional asymmetric structures which can manipulate the metamaterial absorber’s working bandwidth with maintaining the other inherent advantages. As an example, a broadband terahertz perfect absorber is designed to confirm its effectiveness. The absorber’s each cell integrates four sectional asymmetric rings and the entire structure composed of Au and Si3N4 is only 1.9 μm thick. The simulation results show the bandwidth with absorptivity being larger than 90% is extended by about 2.8 times comparing with the conventional square ring absorber. The composable small cell, ultra-thin and broadband absorption with polarization and incident angle insensitivity will make the absorber suitable for the applications of focal plane array terahertz imaging.

AbstractAn environment-friendly iron functionalized chitosan elctrospun nanofiber (ICS-ENF) was synthesized for trace arsenate removal from water. The ICS-ENF was fabricated by electrospinning a mixture of chitosan, PEO and Fe3+ followed by crosslinking with ammonia vapor. The physicochemical properties of ICS-ENF were characterized by FESEM, TEM-EDX and XRD. The ICS-ENF was found to be highly effective for As(V) adsorption at neutral pH. The As(V) adsorption occurred rapidly and achieved equilibrium within 100 min, which was well fitted by pseudo-second-order kinetics model. The As(V) adsorption decreased with increased ionic strength, suggesting an outer-sphere complexation of As(V) on ICS-ENF. Freundlich model well described the adsorption isotherm and the maximum adsorption capacity was up to 11.2 mg/g at pH 7.2. Coexisting anions of chloride and sulfate showed negligible influence on As(V) removal, but phosphate and silicate significantly reduced As(V) adsorption by competing for adsorption sites. FTIR and XPS analysis demonstrated –NH, –OH and C–O were responsible for As(V) uptake. ICS-ENF was easily regenerated using 0.003 M NaOH and the removal rate remained above 98% after ten successively adsorption-desorption recycles. This study extends the potential applicability of electrospun nanofibers for water purification and provides a promising approach for As(V) removal from water.

Published: August 2016

Ordered arrays of substrate supported gold nanodots are fabricated on c‐Si as substrate. Electron beam lithography followed by DC sputter coating was used for the fabrication of ordered gold nanodots over a 1 × 1 cm2 area on c‐Si substrate. The fabricated ordered arrays of gold nanodots were characterised through the reflectance spectra. Reduction of 60.67% in reflectance was exhibited by ordered gold nanodots when compared with bare c‐Si. For comparison, a random gold nanoparticle array of approximately same particle size was fabricated and the reflectance was compared with the ordered array. It was found that the reflectance of ordered array is 52.27% less than that of random array. This route is suitable for fabrication of large area ordered gold nanodots which has applications in photovoltaic industry.

Published: August 2016

Tunnel‐field‐effect transistors (TFETs) operate by quantum band‐to‐band tunnelling and display a steeper subthreshold slope than MOSFETs which substantially diminishes the standby current. This work explores the TFET‐based SRAM utilisation for Low STandby Power applications. An 8 T TFET SRAM cell operating at VDD = 1 V, which, in contrast to other 6 T TFET SRAMs, is write‐disturb‐ and half‐selection‐free is proposed. Simulations based on 30 nm p‐ and n‐TFETs models relying on ID, CGS, CGD vs. VGS, and VDS look‐up tables extracted from TCAD, indicate that the proposed cell has a Read SNM and a Write SNM of 120 and 200 mV, respectively, which are well above state of the art values repotted in the literature. When utilised in an 128 × 128‐bit memory array the proposed cell enables read and write operation at 3.84 GHz and 806 MHz, respectively, and a cell leakage of less than 2fA/bit, which makes it an excellent choice for Internet of Things applications.

Published: August 2016

Significance
Proteinaceous deposits composed primarily of amyloid fibrils of α-synuclein are a hallmark of a range of neurological disorders including Parkinson’s disease. Mutations of the gene encoding α-synuclein have been associated with familial variants of Parkinson’s disease and lead to early- and late-onset forms of the disease. Using a combination of experimental and theoretical approaches specifically designed for the study of α-synuclein, we report that the mutations dramatically affect the rate of lipid-induced fibril production and surface-catalyzed fibril amplification processes. Such a systematic study provides new insights into the influence that single-amino acid replacements in α-synuclein can have on the two steps of α-synuclein aggregation that are likely to be crucial for disease: the initial formation of aggregates and their proliferation.

Published: August 2016

Significance
Reconstructing subsistence practices of ancient hunter-gatherers requires quantitative data on food resources, which rarely preserve. Here we use chemical profiling of hearth sediments from three Ice Age occupations in Alaska (13,200–11,500 years ago), including compound-specific stable isotope analyses and a Bayesian mixing model, to estimate proportional contributions of marine (salmon), freshwater, and terrestrial resources. The model is verified through zooarchaeological analyses and demonstrates the importance of salmonid and freshwater resources to these early Americans. Our study also provides evidence for the earliest use of salmon in the Americas.

SignificanceEndoplasmic reticulum (ER)-associated degradation (ERAD) mediated by the E3 ubiquitin ligase Hrd1 controls ER stress through clearance of misfolded proteins. However, the physiological roles—in particular, the cell- and organ-specific functions of Hrd1 ERAD—remain undefined. Here we demonstrate that Hrd1 ERAD governs a critical checkpoint of B-cell immunity via controlling the activation-induced apoptosis of B cells. At the molecular level, Hrd1 functions as an ubiquitin ligase for the death receptor CD95/Fas. Given the fact of the ubiquitous roles of Fas in cell death and the ubiquitous expression of the antiapoptotic ubiquitin ligase Hrd1, Hrd1-mediated Fas degradation is likely a common biological mechanism in regulating Fas-induced cell death.

Published: August 2016

SignificancePre-mRNA splicing generates protein diversity, is involved in the regulation of cellular differentiation, and can be epigenetically regulated by histone modifications. Chromatin binding proteins, which recognize histone modifications, recruit splicing regulators to methylated histones around tissue-specific splicing regions and regulate pre-mRNA splicing. However, the interplay of epigenetic factors and the splicing machinery during spermatogenesis remains unclear. Here, we show that epigenetic regulation of pre-mRNA splicing is required for spermatogenesis and male fertility. Thus, novel splicing diversity is important for spermatogenesis, and defects in this system may trigger disease.

Significance
Our work shows a remarkable synergy between physiological levels of vitamin C and 5-aza-CdR. The combination enhances the viral mimicry response to DNA methyltransferase inhibitors, including the upregulation of endogenous retroviruses in the dsRNA form and the induction of viral defense pathways. Because patients with hematological and other cancers are often markedly vitamin C deficient, the addition of vitamin C to treatment protocols may be a straightforward way to increase the clinical efficacy of such drugs in patients with myelodysplastic syndrome and leukemia.

AbstractObjectives: To improve well‐being and performance indicators in a group of Australian Football League (AFL) players via a six‐week sleep optimisation programme. Design: Prospective intervention study following observations suggestive of reduced sleep and excessive daytime sleepiness in an AFL group. Methods: Athletes from the Adelaide Football Club were invited to participate if they had played AFL senior‐level football for 1–5 years, or if they had excessive daytime sleepiness (Epworth Sleepiness Scale [ESS] >10), measured via ESS. An initial education session explained normal sleep needs, and how to achieve increased sleep duration and quality. Participants (n = 25) received ongoing feedback on their sleep, and a mid‐programme education and feedback session. Sleep duration, quality and related outcomes were measured during week one and at the conclusion of the six‐week intervention period using sleep diaries, actigraphy, ESS, Pittsburgh Sleep Quality Index, Profile of Mood States, Training Distress Scale, Perceived Stress Scale and the Psychomotor Vigilance Task. Results: Sleep diaries demonstrated an increase in total sleep time of approximately 20 min (498.8 ± 53.8 to 518.7 ± 34.3; p < .05) and a 2% increase in sleep efficiency (p < 0.05). There was a corresponding increase in vigour (p < 0.001) and decrease in fatigue (p < 0.05). Conclusions: Improvements in measures of sleep efficiency, fatigue and vigour indicate that a sleep optimisation programme may improve athletes’ well‐being. More research is required into the effects of sleep optimisation on athletic performance.
Influence of Tb on easy magnetization direction and magnetostriction of ferromagnetic Laves phase GdFe2 compounds*
Authors: Murtaza Adil , Yang Sen , Zhou Chao , Song Xiaoping 
Published: August 2016

Abstract
The crystal structure, magnetization, and spontaneous magnetostriction of ferromagnetic Laves phase GdFe2 compound have been investigated. High resolution synchrotron x-ray diffraction (XRD) analysis shows that GdFe2 has a lower cubic symmetry with easy magnetization direction (EMD) along [100] below Curie temperature T
C. The replacement of Gd with a small amount of Tb changes the EMD to [111]. The Curie temperature decreases while the field dependence of the saturation magnetization (M
s) measured in temperature range 5–300 K varies with increasing Tb concentration. Coercivity H
c increases with increasing Tb concentration and decays exponentially as temperature increases. The anisotropy in GdFe2 is so weak that some of the rare-earth substitution plays an important role in determining the easy direction of magnetization in GdFe2. The calculated magnetostrictive constant λ
100 shows a small value of 37×10−6. This value agrees well with experimental data 30×10−6. Under a relatively small magnetic field, GdFe2 exhibits a V-shaped positive magnetostriction curve. When the field is further increased, the crystal exhibits a negative magnetostriction curve. This phenomenon has been discussed in term of magnetic domain switching. Furthermore, magnetostriction increases with increasing Tb concentration. Our work leads to a simple and unified mesoscopic explanation for magnetostriction in ferromagnets. It may also provide insight for developing novel functional materials.

AbstractBackground.Physical activity can enhance cognitive functions in both animals and humans. We hypothesized that physically active video gaming could: i) improve cognitive functions and ii) improve the execution of activities of daily living among survivors of childhood brain tumors.Methods.Children 7 to 17 years old who completed treatment, including radiotherapy, for a brain tumor 1 to 5 years earlier were randomized to either intervention or waiting list. After 10 to 12 weeks the groups crossed over. The intervention consisted of active video gaming, using a motion-controlled video console (Nintendo Wii), for a minimum of 30 minutes a day, 5 days a week and weekly Internet-based coaching sessions. Evaluations before and after each period included tests of the execution of activities of daily living, using the Assessment of Motor and Process Skills (AMPS) and cognitive tests. Test scores before and after the intervention were compared. A parallel group comparison was performed as a sensitivity analysis.Results.All 13 children enrolled completed the program. Compared to baseline, the motor (P= .012) and process (P=.002) parts of AMPS improved significantly after active video gaming. In the parallel group analysis the improvement in the process part of AMPS remained statistically significant (P= .029), but not the change in AMPS motor score (P= .059). No significant change was found in cognitive tests although there were trends for improvement in sustained attention (P = .090) and selective attention (P = .078).Conclusion.In this pilot study, active video gaming used as a home-based intervention for childhood brain tumor survivors improved motor and process skills in activities of daily living.
Andrew Marvell
Authors: Mottram Stewart 
Published: August 2016

Andrew Marvell (b. 1621–d. 1678) is today one of the best known of English 17th-century poets, his poems frequently anthologized and studied in school and university syllabi. He was born on 31 March 1621 at Winestead-in-Holderness, fourteen miles southeast of Kingston-upon-Hull. Marvell’s family moved to Hull three years later when his father, a Church of England minister, was appointed master of the Charterhouse, an almshouse for the poor just north of Hull’s town walls. Marvell attended Hull Grammar School between 1629 and 1633, leaving for Trinity College, Cambridge, in December 1633 and traveling in mainland Europe throughout the civil war years in the 1640s. Marvell’s Yorkshire connections later led him to Nun Appleton, near York, where in 1650–1652 he worked as tutor to the daughter of Thomas, Lord Fairfax, the former general of the New Model Army. He also tutored William Dutton, ward of Oliver Cromwell, and worked as a civil servant in Cromwell’s Protectorate government, assisting the poet, John Milton, in Milton’s work at the post of Latin Secretary. In 1659, Marvell was elected a Member of Parliament for Hull, a post he held until his sudden death in August 1678 of a fever he had contracted on a visit to Hull “about the Towns affaires.” Marvell’s poetry has not always been as well received as it is today. Few poems were published in his lifetime, and in the eighteenth and nineteenth centuries he was better known as a political controversialist, the author of several prose pamphlets attacking establishment figures in church and state in the 1670s. T. S. Eliot’s influential essay, published in 1921, marked the rise of Marvell’s reputation as a metaphysical poet, but it also had the effect of sidelining Marvell’s political writings and parliamentary career. Recent scholarship has helped assemble a clearer picture of Marvell’s life and times, and a fuller understanding of his complex political and religious views has also helped forge better links between Marvell’s poetry and his political writings. Recent years have seen the publication of new biographies and new editions of Marvell’s complete poems and prose, helping new generations of students and scholars assemble a complete picture of this most complex of 17th-century writers.
Trends and Correlates of Cannabis-involved Emergency Department Visits: 2004 to 2011
Authors: Zhu He , Wu Li-Tzy 
Published: August 2016

Objectives:
To examine trends and correlates of cannabis-involved emergency department (ED) visits in the United States from 2004 to 2011.

Methods:
Data were obtained from the 2004 to 2011 Drug Abuse Warning Network. We analyzed trend in cannabis-involved ED visits for persons aged ≥12 years and stratified by type of cannabis involvement (cannabis-only, cannabis-polydrug). We used logistic regressions to determine correlates of cannabis-involved hospitalization versus cannabis-involved ED visits only.

Results:
Between 2004 and 2011, the ED visit rate increased from 51 to 73 visits per 100,000 population aged ≥12 years for cannabis-only use (P value for trend = 0.004) and from 63 to 100 for cannabis-polydrug use (P value for trend < 0.001). Adolescents aged 12–17 years showed the largest increase in the cannabis-only-involved ED visit rate (rate difference = 80 per 100,000 adolescents). Across racial/ethnic groups, the most prevalent ED visits were noted among non-Hispanic blacks. Among cannabis-involved visits, the odds of hospitalization (vs ED visits only) increased with age strata compared with age 12 to 17 years.

Conclusions:
These findings suggest a notable increase in the ED visit numbers and rates for both the use of cannabis-only and cannabis-polydrug during the studied period, particularly among young people and non-Hispanic blacks.
