One of the key necessary steps to prevent human neurological disorders is the efficient disruption of protein aggregation or amyloid fibril. In this article, we have explored the effect of three amphiphilic surface active ionic liquids (SAILs) namely 1-methyl-3-octylimidazolium chloride ([C8mim]Cl), 1-dodecyl-3-methyllimidazolium chloride ([C12mim]Cl) and 1-hexadecyl-3-methyllimidazolium chloride ([C16mim]Cl) having concentration of 5.8 mM, 0.29 mM and 0.08 mM respectively on bovine serum albumin (BSA) and human serum albumin (HSA) fibril...

Absence or minimization of PVL after TAVR and its potential association with higher rates of PPM placement has been the Achilles' heel of TAVR procedures. Pre-existing RBBB and depth of implantation are independent predictors of PPM need after Lotus valve implantation. Optimization of device design, increased operator experience, and focus on accurate device placement seem to result in decreased need for PPM after Lotus valve implantation.

To solve the unavailability of a traditional strapdown inertial navigation system (SINS) for unmanned underwater vehicles (UUVs) in the polar region, a polar grid navigation algorithm for UUVs is proposed in this paper. Precise navigation is the basis for UUVs to complete missions. The rapid convergence of Earth meridians and the serious polar environment make it difficult to establish the true heading of the UUV at a particular instant. Traditional SINS and traditional representation of position are not suitable in the polar region...

Localized surface plasmon polaritons (SPPs), which can decay non-radiatively into hot carriers, have been widely employed to extend the responses of traditional semiconductor-based photocatalytic and photovoltaic devices to sub-bandgap photons. However, radiative decay is unavoidable and adverse to device performances. Here, we propose to take advantage of propagating SPPs, another form of SPPs, which possess non-radiative decay only. A special gold-titanium dioxide nanowire array with each nanowire capped with a nanocone is proposed...

Ouranosaurus nigeriensis is an iconic African dinosaur taxon that has been described on the basis of two nearly complete skeletons from the Lower Cretaceous Gadoufaoua locality of the Ténéré desert in Niger. The entire holotype and a few bones attributed to the paratype formed the basis of the original description by Taquet (1976). A mounted skeleton that appears to correspond to O. nigeriensis has been on public display since 1975, exhibited at the Natural History Museum of Venice. It was never explicitly reported whether the Venice specimen represents a paratype and therefore, the second nearly complete skeleton reported in literature or a third unreported skeleton...

Results are reported from an improved measurement of ν_{μ}→ν_{e} transitions by the NOvA experiment. Using an exposure equivalent to 6.05×10^{20} protons on target, 33 ν_{e} candidates are observed with a background of 8.2±0.8 (syst.). Combined with the latest NOvA ν_{μ} disappearance data and external constraints from reactor experiments on sin^{2}2θ_{13}, the hypothesis of inverted mass hierarchy with θ_{23} in the lower octant is disfavored at greater than 93% C.L. for all values of δ_{CP}.

Dinghy sailors lean their upper body over the windward side of the boat ('hiking') to keep the boat's balance and maximise its speed. Sustaining the hiking position is essential for competitive performance and this study examined sport-specific differences of muscles relevant for hiking in elite sailors. Knee extensor muscle strength as well as trunk muscle strength, muscle endurance and muscle thickness were assessed in elite dinghy sailors (n = 15) and compared to matched, non-sailing controls (n = 15)...

As more and more quality of life becomes a goal of personnel and sustainable development, long-distance travel is becoming more widespread. Sailing around the world is an example of this evolution. The keys to a successful journey are rigorous preparation and adherence to some prevention rules. Medical or surgical emergencies are rare, and can often be dealt with by remote medical contact. New communication technologies such as satellite phones make it possible to seek medical advice from professionals, or even for sailers to treat themselves with very short prior training, provided that the required equipment and medicines have been embarked before leaving...

Xiaolong Li, Yan Zheng, Jun Cai, Yunfei Yi
This paper aims at proposing a new wireless indoor localization system (ILS), called TrackCC, based on a commercial type of low-power system-on-chip (SoC), nRF24LE1. This type of chip has only l output power levels and acute fluctuation for a received minimum power level in operation, which give rise to many practical challenges for designing localization algorithms. In order to address these challenges, we exploit the Markov theory to construct a ( l + 1 ) × ( l + 1 ) -sized state transition matrix to remove the fluctuation, and then propose a priority-based pattern matching algorithm to search for the most similar match in the signal map to estimate the real position of unknown nodes...

Metasurface serves as a promising plasmonic sensing platform for engineering the enhanced light-matter interactions. Here, a hyperbolic metasurface with the nanogroove structure in the subwavelength scale is designed. This metasurface is able to modify the wavefront and wavelength of surface plasmon wave with the variation of the nanogroove width or periodicity. At the specific optical frequency, surface plasmon polaritons are tightly confined and propagated with a diffraction-free feature due to the epsilon-near-zero effect...

Chemical flooding with surfactants for reducing oil-brine interfacial tensions (IFTs) to mobilize residual oil trapped by capillary forces has a great potential for Enhanced Oil Recovery (EOR). Surface-active ionic liquids (SAILs) constitute a class of surfactants that has recently been proposed for this application. For the first time, SAILs or their blends with an anionic surfactant are studied by determining equilibrium phase behavior for systems of about unit water-oil ratio at various temperatures. The test fluids were model alkane and aromatic oils, NaCl brine, and synthetic hard seawater (SW)...

This paper presents the design, manufacturing and testing of a Dual Accelerometer Vector Sensor (DAVS). The device was built within the activities of the WiMUST project, supported under the Horizon 2020 Framework Programme, which aims to improve the efficiency of the methodologies used to perform geophysical acoustic surveys at sea by the use of Autonomous Underwater Vehicles (AUVs). The DAVS has the potential to contribute to this aim in various ways, for example, owing to its spatial filtering capability, it may reduce the amount of post processing by discriminating the bottom from the surface reflections...

Perinatal mood and anxiety disorders (PMAD) are the most common, yet under-diagnosed and undertreated complication of pregnancy, affecting up to 50% of pregnant and parenting teens. PMAD are a global health issue that can have devastating effects on the mental, physical, emotional, developmental health, and social life of the mother, infant, and family. Adolescents present with similar symptoms of PMAD as their adult counterparts, but also experience isolation from their peer group and lack of resources and coping strategies, as well as difficulty sleeping and lack of concentration and ability to focus...

X F Shen, B Qiao, H Zhang, S Kar, C T Zhou, H X Chang, M Borghesi, X T He
A method to achieve stable radiation pressure acceleration (RPA) of heavy ions from laser-irradiated ultrathin foils is proposed, where a high-Z material coating in front is used. The coated high-Z material, acting as a moving electron repository, continuously replenishes the accelerating heavy ion foil with comoving electrons in the light-sail acceleration stage due to its successive ionization under laser fields with Gaussian temporal profile. As a result, the detrimental effects such as foil deformation and electron loss induced by the Rayleigh-Taylor-like and other instabilities in RPA are significantly offset and suppressed so that stable acceleration of heavy ions are maintained...

Introduction In quite a few patients with bipolar disorder there is no real alternative to lithium treatment despite impaired kidney function. Is it possible to continue lithium treatment despite kidney malfunction by changing dosage and/or frequency of administration? Case Report We report on a 65-year-old woman suffering from bipolar-I disorder who had been on lithium treatment for many decades. While on lithium, the glomerular filtration rate (GFR) decreased constantly. A decision had to be made whether to switch to a more tolerable o...
