Transition Metal Chalcogenide Tin Sulfide Nanodimensional Films Align Liquid Crystals

Transition metal chalcogenide tin sulfide (SnS) films as alternative noncontact alignment layer for liquid crystals, have been demonstrated and investigated. The SnS has an anisotropic atomic chain structure similar to black Phosphorous which causes the liquid crystal molecules to align without the need for any additional surface treatments. The high anisotropic nature of SnS promotes the alignment of the easy axis of liquid crystal molecules along the periodic atomic grooves of the SnS layer. The atomically thin SnS layers were deposited on indium tin oxide films on glass substrates, at room temperature by chemical vapor deposition. The device characteristics are comparable to those commercially available, which use photo-aligning polymer materials. We measured threshold voltage of 0.92V, anchoring energy of 1.573x10^(-6) J/m^2, contrast ratio better than 71:1 and electro-optical rise/fall times of 80/390ms, respectively for ~11 micron thick liquid crystal device as expected.
Physical evidence for dark energy

The authors present measurements of the angular cross-correlation between luminous red galaxies from the Sloan Digital Sky Survey and the cosmic microwave background temperature maps from the Wilkinson Microwave Anisotropy Probe. They find a statistically significant achromatic positive correlation between these two data sets, which is consistent with the expected signal from the late Integrated Sachs-Wolfe (ISW) effect. they do not detect any anti-correlation on small angular scales as would be produced from a large Sunyaev-Zel'dovich (SZ) effect, although they do see evidence for some SZ effect for their highest redshift samples. Assuming a flat universe, their preliminary detection of the ISW effect provides independent physical evidence for the existence of dark energy.
UNIFIED TREATMENT OF SMALL- AND LARGE-SCALE DYNAMOS IN HELICAL TURBULENCE

Helical turbulence may provide the key to the generation of large-scale magnetic fields. Turbulence also generically leads to rapidly growing small-scale magnetic fields. These two processes are usually studied separately. We give here a unified treatment of both processes, in the case of random fields, incorporating also a simple model nonlinear drift. We uncover an interesting plausible saturated state of the small-scale dynamo and a novel analogy between quantum mechanical (QM) tunneling and the generation of large-scale fields. A field generated by the small-scale dynamo, can ``tunnel'' to produce large-scale correlations, which in steady state, correspond to a force-free ``mean'' field.
Creation of a persistent current and vortex in a Bose-Einstein condensate of alkali-metal atoms

It is shown theoretically that a persistent current can be continuously created in a Bose-Einstein condensate (BEC) of alkali-metal atoms confined in a multiply connected region by making use of a spin degree of freedom of the order parameter of a BEC. We demonstrate that this persistent current is easily transformed into a vortex. Relaxation processes of these BEC after the confining field is turned off are also studied, so that our analyses are compared with time-of-flight experiments. The results are shown to clearly reflect the existence of a persistent current.
Smearing Distributions and their use in Financial Markets

It is shown that superpositions of path integrals with arbitrary Hamiltonians and different scaling parameters v ("variances") obey the Chapman-Kolmogorov relation for Markovian processes if and only if the corresponding smearing distributions for v have a specific functional form. Ensuing "smearing" distributions substantially simplify the coupled system of Fokker-Planck equations for smeared and un-smeared conditional probabilities. Simple application in financial models with stochastic volatility is presented.

Finite Element Method for Solving the Collective Nuclear Model with Tetrahedral Symmetry

We apply a new calculation scheme of a finite element method (FEM) for solving an elliptic boundary-value problem describing a quadrupole vibration collective nuclear model with tetrahedral symmetry. We use of shape functions constructed with interpolation Lagrange polynomials on a triangle finite element grid and compare the FEM results with obtained early by a finite difference method.
The Effect of Different Parameters on Electrochemical Removal of Ampicillin Using New Generation Sn/Sb/Ni-Ti Anodes

In this study, it was aimed to investigate the feasibility of new generation and stable Sn/Sb/Ni-Ti anodes for treatment of wastewater containing Ampicillin (AMP) antibiotic by electrochemical oxidation processes. Ampicillin concentration was 0.05 g L-1 in the aqueous solution. Residual ampicillin conc. was measured with Ultra-Performance Liquid Chromatography (UPLC) – Photodiode Array Detector (PDA). While, several parameters were evaluated such salt type and concentration, pH, current density, and anode-cathode distance; salt type and concentration was found as the most effective parameter for the removal of COD, TOC and AMP. Two different type of salts were used for this purpose; sodium chloride (NaCl) and potassium chloride (KCl). However, the removal efficiencies were found more higher in the presence of potassium chloride (KCl) when compared to sodium chloride (NaCl), generally. In the presence of KCl, ≥99% removal of COD and AMP after 60 min, pH 8, 50 mA/cm2, 750 mg/L and 1cm distance between anodes. However, in the presence of sodium chloride (NaCl), complete removal of COD and AMP after 90 min, pH 8, 50 mA/cm2, 2500 mg/L and 1cm distance between anodes.
Calculation of transmission tunneling current across arbitrary potential barriers

This paper presents a simple method for accurately calculating quantum mechanical transmission probability and current across arbitrary potential barriers by using the multistep potential approximation. This method is applicable to various potential barriers and wells, including continuous variations of potential energy and electron effective mass. Various potential barrier structures and a hot‐electron transistor are analyzed to show the feasibility of this method.
Internal vertebral morphology of bony fishes matches the mechanical demands of different environments

Abstract Fishes have repeatedly evolved characteristic body shapes depending on how close they live to the substrate. Pelagic fishes live in open water and typically have narrow, streamlined body shapes; benthic and demersal fishes live close to the substrate; and demersal fishes often have deeper bodies. These shape differences are often associated with behavioral differences: pelagic fishes swim nearly constantly, demersal fishes tend to maneuver near the substrate, and benthic fishes often lie in wait on the substrate. We hypothesized that these morphological and behavioral differences would be reflected in the mechanical properties of the body, and specifically in vertebral column stiffness, because it is an attachment point for the locomotor musculature and a central axis for body bending. The vertebrae of bony fishes are composed of two cones connected by a foramen, which is filled by the notochord. Since the notochord is more flexible than bony vertebral centra, we predicted that pelagic fishes would have narrower foramina or shallower cones, leading to less notochordal material and a stiffer vertebral column which might support continuous swimming. In contrast, we predicted that benthic and demersal fishes would have more notochordal material, making the vertebral column more flexible for diverse behaviors in these species. We therefore examined vertebral morphology in 79 species using micro‐computed tomography scans. Six vertebral features were measured including notochordal foramen diameter, centrum body length, and the cone angles and diameters for the anterior and posterior vertebral cones, along with body fineness. Using phylogenetic generalized least squares analyses, we found that benthic and pelagic species differed significantly, with larger foramina, shorter centra, and larger cones in benthic species. Thus, morphological differences in the internal shape of the vertebrae of fishes are consistent with a stiffer vertebral column in pelagic fishes and with a more flexible vertebral column in benthic species.
Molecular Clouds Associated with the Type Ia SNR N103B in the Large Magellanic Cloud

N103B is a Type Ia supernova remnant (SNR) in the Large Magellanic Cloud (LMC). We carried out new 12CO(J = 3–2) and 12CO(J = 1–0) observations using ASTE and ALMA. We have confirmed the existence of a giant molecular cloud at VLSR ∼ 245 km s−1 toward the southeast of the SNR using ASTE 12CO(J = 3–2) data at an angular resolution of ∼25″ (∼6 pc in the LMC). Using the ALMA 12CO(J = 1–0) data, we have spatially resolved CO clouds along the southeastern edge of the SNR with an angular resolution of ∼1. ″8 (∼0.4 pc in the LMC). The molecular clouds show an expanding gas motion in the position–velocity diagram with an expansion velocity of ∼5 km s−1. The spatial extent of the expanding shell is roughly similar to that of the SNR. We also find tiny molecular clumps in the directions of optical nebula knots. We present a possible scenario that N103B exploded in the wind-bubble formed by the accretion winds from the progenitor system, and is now interacting with the dense gas wall. This is consistent with a single-degenerate scenario.
Contract Strengthening through Constrained Horn Clause Verification

The functional properties of a program are often speciﬁed by providing a contract for each of its functions. A contract of a function consists of a pair of formulas, called a precondition and a postcondition, which, respectively, should hold before and after execution of that function. It might be the case that the contracts supplied by the programmer are not adequate to allow a veriﬁcation system to prove program correctness, that is, to show that for every function, if the precondition holds and the execution of the function terminates, then the postcondition holds. We address this problem by providing a technique which may strengthen the postconditions of the functions, thereby improving the ability of the veriﬁer to show program correctness. Our technique consists of four steps. First, the translation of the given program, which may manipulate algebraic data structures (ADTs), and its contracts into a set of constrained Horn clauses (CHCs) whose satisﬁability implies the validity of the given contracts. Then, the derivation, via CHC transformation performed by the VeriCaT tool, of a new set of CHCs that manipulate only basic sorts (such as booleans or integers) and whose satisﬁability implies the satisﬁability of the original set of clauses. Then, the construction of a model, if any, of the new, derived CHCs using the CHC solver SPACER for basic sorts. Finally, the translation of that model into the formulas that suitably strengthen the postconditions of the given contracts. We will present our technique through an example consisting of a Scala program for reversing lists. Note that the S TAINLESS veriﬁer is not able to prove the correctness of that program when considering the given contracts, while it succeeds when considering the contracts with the strengthened postconditions constructed by applying our technique.
Improved superconducting properties in nanocrystalline bulk MgB2

High density nanocrystalline MgB2 bulk superconductors with distinctly improved pinning were prepared by mechanical alloying of Mg and B powders at ambient temperatures followed by hot pressing. The nanocrystalline samples reveal high jc=105 A/cm2 at 20 K and 1 T together with an irreversibility line strongly shifted towards higher fields resulting in Hirr(T)∼0.8 Hc2(T), whereas typically Hirr(T)∼0.5 Hc2(T) is observed for untextured bulk samples. These values exceed those of all other reported bulk samples and are in the range of values for thin films. The improved pinning of this material, which mainly consists of spherical grains about 40–100 nm in size, is attributed to the large number of grain boundaries in the nanocrystalline state.
A GPU-based incompressible Navier–Stokes solver on moving overset grids

In pursuit of obtaining high fidelity solutions to the fluid flow equations in a short span of time, graphics processing units (GPUs) which were originally intended for gaming applications are currently being used to accelerate computational fluid dynamics (CFD) codes. With a high peak throughput of about 1 TFLOPS on a PC, GPUs seem to be favourable for many high-resolution computations. One such computation that involves a lot of number crunching is computing time accurate flow solutions past moving bodies. The aim of the present paper is thus to discuss the development of a flow solver on unstructured and overset grids and its implementation on GPUs. In its present form, the flow solver solves the incompressible fluid flow equations on unstructured/hybrid/overset grids using a fully implicit projection method. The resulting discretised equations are solved using a matrix-free Krylov solver using several GPU kernels such as gradient, Laplacian and reduction. Some of the simple arithmetic vector calculations are implemented using the CU++: An Object Oriented Framework for Computational Fluid Dynamics Applications using Graphics Processing Units, Journal of Supercomputing, 2013, doi:10.1007/s11227-013-0985-9 approach where GPU kernels are automatically generated at compile time. Results are presented for two- and three-dimensional computations on static and moving grids.
Low Left Ventricular Mass Index in Gilbert Syndrome? Arterial Stiffness Might Be the Missing Piece of the Puzzle

Zengin et al proposed that preserved endothelial function in patients with Gilbert syndrome is due to the anti-oxidant effects of raised bilirubin levels. Endocan levels and left ventricular mass index (LVMI) were lower in patients with Gilbert syndrome than in control subjects. Several factors can affect left ventricular mass and LVMI. Gender is a major determinant (higher LVMI in males). Blood pressure (BP), which causes pressure load, and physical activity were also associated with increased LVMI. Left ventricular mass also depends on loading conditions, and valvular diseases may affect LVMI because of volume or pressure overload. Relative wall thickness estimates the geometry of left ventricular remodeling. Eccentric remodeling usually develops under conditions with volume overload while concentric remodeling usually occurs with pressure overload. In the current study, although the female-to-male ratio was significantly higher in the control group, LVMI was, contrary to expectations, significantly higher than in patients with Gilbert syndrome. Production of endocan is induced by endothelial damage and is driven via proinflammatory cytokines. Endocan levels are elevated in the early phases of hypertension and are a sign of higher pulse wave velocity and increased arterial stiffness. Therefore, a decreased oxidative burden and lower endocan levels due to raised bilirubin might improve both arterial stiffness and BP; this could explain the lower LVMI in patients with Gilbert syndrome. It would be useful if the BP was also evaluated. Moreover, because valvular diseases may affect LVMI, as mentioned above, echocardiographic measures would help further clarify the relationship between bilirubin levels and LVMI.
OXA-48-producing Enterobacterales in different ecological niches in Algeria: clonal expansion, plasmid characteristics and virulence traits.

OBJECTIVES To investigate the prevalence and molecular characteristics of OXA-48-carbapenemase-producing Enterobacterales strains recovered from various ecological niches in Algeria. METHODS In total, 3309 samples were collected from different ecological niches (human carriage, animal farms, wild animals, pets, food products, aquatic environment and wastewater treatment plants) distributed among six provinces in Algeria between December 2015 and April 2017. The potential presence of OXA-48-producing Enterobacterales isolates was screened on selective medium. Resistance and virulence profiles were characterized by PCR and sequencing. The clonal relatedness of the different isolates was studied using Rep-PCR and MLST. Conjugation was performed for all OXA-48-producing isolates. The plasmids were analysed by PCR-based replicon typing and WGS. RESULTS A total of 78 OXA-48-producing Enterobacterales isolates were detected from 3309 samples (2.4%). OXA producers were observed in all the screened sources. The blaCTX-M-15 gene was only observed in two isolates. Clonality analysis revealed distinct lineages of the isolates and a clonal expansion of Klebsiella pneumoniae ST13. K. pneumoniae and Escherichia coli had few virulence factors. Plasmid analysis confirmed that all the isolates harboured a very similar transferable plasmid (belonging to IncL) with a similar structure to the pOXA-48a plasmid carried by K. pneumoniae strain Kp11978. CONCLUSIONS This study suggests a global dissemination of OXA-48-producing Enterobacterales in different niches due mainly to the spread of an epidemic plasmid. Furthermore, it clearly shows that K. pneumoniae and commensal E. coli can be reservoirs of the blaOXA-48 gene, contributing to the dissemination and transfer of this gene to diverse bacteria among different sources.

CrVI contaminated groundwater in the Mediterranean: Case study from Mersin, Turkey

Increasing population, industrialization, agricultural and tourism activities in Mediterranean countries not only increase the water demand but also led to deterioration of water quality. Water quality degredation is a common problem in all circum-Mediterranean countries and there is an increasing need for development of a common approach in tackling water resources management problems. ERANETMED CrITERIA project aims to assist the water resources management organizations with an optimization tool that includes documentation and database for decision support. Greece, Italy, Turkey, Cyprus, Jordan and Omman are the partners of the project. The project area in Turkey covers Mersin city and its surrounding. This region is located on the Mediterranean coast and consist of two main hydrogeological parts; the Coastal Aquifer and the Hillside Aquifer. The Coastal Aquifer is represented by a deltaic environment and The Hillside Aquifer is composed mainly of sedimentary and ophiolitic rocks. Within the scope of the study, surface and groundwater samples were collected from the region in May 2017, October-November 2017 and May-June 2018. About 50 sites were sampled in each period. It is determined that none of the samples has above the 50 µg/L limit of EU drinking water standard for total Cr, but some of the samples have CrVI contents above 10 µg/L. CrVI is regarded as a potential carcinogen.
Generalized form factors, generalized parton distributions, and the spin contents of the nucleon

With a special intention of clarifying the underlying spin contents of the nucleon, we investigate the generalized form factors of the nucleon, which are defined as the $n$th $x$ moments of the generalized parton distribution functions, within the framework of the chiral quark soliton model. A particular emphasis is put on the pion mass dependence of final predictions, which we shall compare with the predictions of lattice QCD simulations carried out in the so-called heavy pion region around ${m}_{\ensuremath{\pi}}\ensuremath{\simeq}(700\char21{}900)\text{ }\text{ }\mathrm{MeV}$. We find that some observables are very sensitive to the variation of the pion mass. It will be argued that the negligible importance of the quark orbital angular momentum indicated by the LHPC and QCDSF lattice collaborations might be true in the unrealistic heavy pion world, but it is not necessarily the case in our real world close to the chiral limit.
Proton decay and the quantum structure of space–time

Virtual black holes in noncommutative space–time are investigated using coordinate coherent state formalism such that the event horizon of a black hole is manipulated by smearing it with a Gaussian of width [Formula: see text], where θ is the noncommutativity parameter. Proton lifetime, the main associated phenomenology of the noncommutative virtual black holes, has been studied, first in four-dimensional space–time and then generalized to D dimensions. The lifetime depends on θ and the number of space–time dimensions such that it emphasizes on the measurement of proton lifetime as a potential probe for the microstructure of space–time.
