The nematic susceptibility of hole-doped Ba1-xKxFe2As2 and electron-doped Ba(Fe1-xCox)2As2 iron-based superconductors is obtained from measurements of the elastic shear modulus using a three-point bending setup in a capacitance dilatometer. Nematic fluctuations, although weakened by doping, extend over the whole super…
In this paper, Fig. The correct total e-p coupling q = q for each wave vector q is given in the corrected Fig. None of the conclusions in the original paper are affected. FIG. 5. (Color online) Electron-phonon coupling parameter q for sc As at 30, 40, and 50 GPa. The values of the peak at R are 35, 9.8, and 6.1 for 30…

GaAs nanopillars with 150 nm - 200 nm long axial InGaAs inserts are grown by\nMOCVD via catalyst-free selective-area-epitaxy (SAE). The alloy composition of\nthe InGaAs region, as determined by room-temperature photoluminescence (PL),\ndepends critically on the pitch and diameter of the selective-area pattern\ngeometr…
We study the presumably unnecessary convexity hypothesis in the theorem of Chung et al. [CFS] on perimeter-minimizing planar tilings by convex pentagons. We prove that the theorem holds without the convexity hypothesis in certain special cases, and we offer direction for future research.
This article reports a comprehensive investigation of the average and local structure of La5.6WO12 delta, which has excellent mixed proton, electron and oxide ion conduction suitable for device applications. Synchrotron X ray and neutron powder diffraction show that a cubic fluorite supercell describes the average str…
This specification covers powder metallurgy (PM) structural components fabricated from commercially pure (CP) (that is, unalloyed) titanium powder, pre-alloyed powders, and mixtures of elemental powders or mixtures of elemental powders and pre-all
The Higgs boson mass and the abundance of dark matter constrain the CMSSM/mSUGRA supersymmetry breaking inputs. A complete map of the CMSSM that is consistent with these two measured quantities is provided. Various “continents,” consisting of non-excluded models, can be organized by their dark mat ter dynamics. The fo…
We have found a mistake in Fig. In the text of the article it is stated that, for obtaining the optimized intra-and intercluster distances d m and D m , a spin-averaged (O 2 ) 2 potential has been employed for the V inter ij
This research aims at understanding the conditions that lead to reaction initiation of polymer-bonded explosives (PBXs) as they undergo mechanical and thermal processes subsequent to impact. To analyze this issue, a cohesive finite element method (CFEM) based finite deformation framework is developed and used to quant…
We address the problem of analyzing sets of noisy time-varying signals that all report on the same process but confound straightforward analyses due to complex inter-signal heterogeneities and measurement artifacts. In particular we consider single-molecule experiments which indirectly measure the distinct steps in a…
We predict that electron-doped silicene is a good two-dimensional electron-phonon superconductor under biaxial tensile strain by first-principles calculations within rigid band approximation. Superconductivity transition temperature of electron-doped silicene can be increased to be above 10 K by 5% tensile strain. Ban…

In this work the angle and amplitude-frequency characteristics of electromechanical characteristics of the receiving transducer with fully electroelasticelektrodirovannoy surface, which is placed in a closed circular layer. Calculated and analyzed the distribution of normal, radial and total cumulative displacement of…
It was researched acoustics characteristics of ring cylindrical transducer, that create from ceramic envelope and coaxial rigid cylindrical acoustic baffle, that placed in inside cavity of envelope. The created annular gap filled with liquid. Was get analytical expressions, that describe sound fields out and inside of…

The desirable combination of corrosion and chemical resistance, strength to weight ratio, flexibility, long-term tensile strength, water tight joints, abrasion resistance, relatively low coefficient of friction, and effective cost have made solid wall polyvinyl chloride (PVC) pipe a popular material for both pressure…
Fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent. The paper describes a mathematical model of proton exchange membrane fuel cells by analyzing the working mechanism of the proton exchange membrane fuel cell. Furtherm…
Tyrosine kinase inhibitors (TKIs) have been recently introduced for treatment of different malignancies. Various cardiovascular toxicities have been reported with TKIs with hypertension being the most common adverse cardiovascular event. We report a case of a 60-year-old woman who developed left renal artery stenosis…
