In this article, we have reported the synthesis and physicochemical characterization of a novel L-glycine amino acid derived cholesterol based surface active ionic liquid (SAIL). This SAIL has been explored for the preparation of ionic liquid (IL)-in-oil microemulsions and vesicles. The formation of IL-in-oil microemulsion is characterized by construction of a ternary phase diagram, dynamic light scattering (DLS) measurement, proton nuclear magnetic resonance (1H NMR) study, fluorescence measurement using coumarin 480 (C-480) as a molecular probe and also by recording the diffusion behavior of the molecular probe rhodamine 6G (R6G) in microemulsion droplets through Fluorescence correlation spectroscopy (FCS) technique...

A large-scale nanostructured low-temperature solar selective absorber is demonstrated experimentally. It consists of a silicon dioxide thin film coating on a rough refractory tantalum substrate, fabricated based simply on self-assembled, closely packed polystyrene nanospheres. Because of the strong light harvesting of the surface nanopatterns and constructive interference within the top silicon dioxide coating, our absorber has a much higher solar absorption (0.84) than its planar counterpart (0.78). Though its absorption is lower than that of commercial black paint with ultra-broad absorption, the greatly suppressed absorption/emission in the long range still enables a superior heat accumulation...

The highly enlarged proboscis in adult thorny-headed worms of the genus Apororhynchus suggests that its inner organization might be specialized as well. However, what kind of changes occurred in the stem line of monogeneric Apororhynchida is widely unknown and there are different conceptions regarding the presence/absence of several muscles. To expand our knowledge on this topic, I examined ethanol-fixed specimens, whole mounts, and semi-thin sections of three Apororhynchus species using the light microscope...

Showing the record strengths and growth-rates, recent hurricanes have highlighted needs for improving forecasts of tropical cyclone intensities most sensitive to models of the air-sea interaction. Especially challenging is the nature of sea-spray supposed to strongly affecting the momentum- and energy- air-sea fluxes at strong winds. Even the spray-generation mechanisms in extreme winds remained undetermined. Basing on high-speed video here we identify it as the bag-breakup mode of fragmentation of liquid in gaseous flows known in a different context...

This Letter reports new results on muon neutrino disappearance from NOvA, using a 14 kton detector equivalent exposure of 6.05×10^{20} protons on target from the NuMI beam at the Fermi National Accelerator Laboratory. The measurement probes the muon-tau symmetry hypothesis that requires maximal θ_{23} mixing (θ_{23}=π/4). Assuming the normal mass hierarchy, we find Δm_{32}^{2}=(2.67±0.11)×10^{-3}  eV^{2} and sin^{2}θ_{23} at the two statistically degenerate values 0.404_{-0.022}^{+0.030} and 0...

Soft robots driven by stimuli-responsive materials have unique advantages over conventional rigid robots, especially in their high adaptability for field exploration and seamless interaction with humans. The grand challenge lies in achieving self-powered soft robots with high mobility, environmental tolerance, and long endurance. We are able to advance a soft electronic fish with a fully integrated onboard system for power and remote control. Without any motor, the fish is driven solely by a soft electroactive structure made of dielectric elastomer and ionically conductive hydrogel...

In this paper, a magnetic field sensor with enhanced sensitivity based on a fiber Fabry-Perot (F-P) cavity formed by a pair of identical fiber Bragg gratings (FBGs) is demonstrated. The F-P cavity which was filled with silicone rubber was bonded to a magnetic alloy at two positions such that when longitudinal strain is applied, the cavity is lengthened while the FBGs was virtually strain-free, effectively magnified the magnetic-field induced strain of the magnetic alloy. The FBGs could also be used for temperature-compensation because the FBG spectrum change is negligible compared to the F-P spectrum...

In October 2015, Zika virus (ZIKV) outbreak the Brazilian Ministry of Health (MoH). In response, the Brazilian Society of Medical Genetics established a task force (SBGM-ZETF) to study the phenotype of infants born with microcephaly due to ZIKV congenital infection and delineate the phenotypic spectrum of this newly recognized teratogen. This study was based on the clinical evaluation and neuroimaging of 83 infants born during the period from July, 2015 to March, 2016 and registered by the SBGM-ZETF. All 83 infants had significant findings on neuroimaging consistent with ZIKV congenital infection and 12 had confirmed ZIKV IgM in CSF...

Trip Gabriel
In this vivid first-person case history, political reporter Trip Gabriel describes experiencing a classic episode of transient global amnesia. He was near the average target age of 61. Although no cause has been established for the syndrome, as with many other patients his episode appears to have been triggered by contact with water: He was racing a sailboat. While remaining alert and handling complex sailing maneuvers, he suddenly developed amnesia that left him with no recollection of finishing two races, returning to shore, drinking a beer with his friends, needing help finding his car, and not knowing where he was or where he lived...

Wormlike micelles were successfully fabricated by the self-assembly of a single-tailed zwitterionic surface-active ionic liquid (SAIL), 3-(1-hexadecyl-3-imidazolio) propanesulfonate β-naphthalene sulfonate (C16IPS-Nsa), in aqueous solutions without any additives. With increasing zwitterionic SAIL concentration, spontaneous transition from micelles to wormlike micelles and then a hexagonal phase occurs. Interestingly, the wormlike micelles are closed, stretched and directionally arranged, which was rarely found in previous research studies...

'A tribute to Dr J. Rogge' aims to systematically review muscle activity and muscle fatigue during sustained submaximal quasi-isometric knee extension exercise (hiking) related to Olympic dinghy sailing as a tribute to Dr Rogge's merits in the world of sports. Dr Jacques Rogge is not only the former President of the International Olympic Committee, he was also an orthopaedic surgeon and a keen sailor, competing at three Olympic Games. In 1972, in fulfilment of the requirements for the degree of Master in Sports Medicine, he was the first who studied a sailors' muscle activity by means of invasive needle electromyography (EMG) during a specific sailing technique (hiking) on a self-constructed sailing ergometer...

BACKGROUND: The updated bedside Schwartz equation requires constant, serum creatinine concentration and height measurements to calculate the estimated glomerular filtration rate (eGFR) in pediatric patients. Unlike the serum creatinine levels, obtaining height information from the laboratory information system (LIS) is not always possible in a clinical laboratory. Recently, the height-independent eGFR equation, the full age spectrum (FAS) equation, has been introduced. We evaluated the performance of height-independent eGFR equation in Korean children with cancer...

Galectins are members of the lectin superfamily. They function as pattern recognition receptors in the innate immune system of vertebrates and invertebrates. A galectin homolog from the triangle sail mussel Hyriopsis cumingii (HcGal2) was cloned and characterized. HcGal2 mRNA was expressed in all tissues examined, displaying particular enrichment in mantle tissue. Interestingly, rHcGAL2 protein was only detected in the mantle, hemocytes, and gills, suggesting that post-transcriptional regulation may occur. HcGal2 expression was induced in the mantle, liver, and hemocytes after exposure to lipopolysaccharides, Gram-negative bacteria (Aeromonas hydrophila), and Gram-positive bacteria (Staphylococcus aureus)...

Proton acceleration from nanometer thin foils with intense laser pulses is investigated experimentally. We analyzed the laser absorptivity by parallel monitoring of laser transmissivity and reflectivity with different laser intensities when moving the targets along the laser axis. A direct correlation between laser absorptivity and maximum proton energy is observed. Experimental results are interpreted in analytical estimation, exhibiting a coexistence of plasma expansion and light-sail form of radiation pressure acceleration (RPA-LS) mechanisms during the entire proton acceleration process based on the measured laser absorptivity and reflectivity...

Contamination by microplastic particles and fibres has been observed in sediment and animals sampled from the Firth of Clyde, West Scotland. In addition to microplastics released during clothes washing, a probable source is polymer ropes in abandoned, lost and discarded fishing and recreational sailing gear. The fragmentation of polypropylene, polyethylene, and nylon exposed to benthic conditions at 10m depth over 12months was monitored using changes in weight and tensile properties. Water temperature and light levels were continuously monitored...
