We report a systematic investigation of Ba(Fe1 xCox)2As2 based on transport and As NMR measurements, and establish the electronic phase diagram. We demonstrate that doping progressively suppresses the uniform spin susceptibility and low frequency spin fluctuations. The optimum superconducting phase emerges at xc ’ 0:08 when the tendency toward spin ordering completely diminishes. Our findings p...

A real hyperelliptic curve X is said to be Gaussian if there is an automorphism α : XC → XC such that α = [−1]C ◦ α, where [−1] denotes the hyperelliptic involution on X. Gaussian curves arise naturally in several contexts, for example when one studies real Jacobians. In the present paper we study the properties of Gaussian curves and we describe their moduli spaces. MSC 2000: 14H15, 14H37, 14P...

2014 Measurements of the NMR absorption line shapes have been used to establish the phase diagram for orientational ordering of the J = 1 molecules in solid mixtures of paradeuterium (J = 1) and orthodeuterium (J = 0) for para concentrations 42 X 75 % and temperatures 0.035 T 2.5 K. As in solid hydrogen, we observe three phases : a rotationally disordered phase, a long range orientationally ord...

Xinnaoshutong capsule (XC) is a traditional Chinese prescription derived from the ripe fruit of Tribulus terrestris L. (TT). Although XC has long been considered as an important herbal medicine, no analytical method of marker compounds for quality assessment is registered in the Chinese Pharmacopoeia. A simple analytical method of twelve marker components was developed and validated by HPLC-VWD...

A series of carbon-based superconductors XC₆ with high Tc were reported recently. In this paper, based on the first-principles calculations, we studied the mechanical properties of these structures, and further explored the XC12 phases, where the X atoms are from elemental hydrogen to calcium, except noble gas atoms. The mechanically- and dynamically-stable structures include HC₆, NC₆, and SC₆ ...

We investigate, for a given smooth closed manifold M , the existence of an algebraic model X for M (i.e., a nonsingular real algebraic variety diffeomorphic to M) such that some nonsingular projective complexification i : X → XC of X admits a retraction r : XC → X. If such an X exists, we show that M must be formal in the sense of Sullivan’s minimal models, and that all rational Massey products...

The ferroelectric degenerate semiconductor Sn1−δTe exhibits superconductivity with critical temperatures, Tc, of up to 0.3 K for hole densities of order 10 21 cm. When doped on the tin site with greater than xc = 1.7(3)% indium atoms, however, superconductivity is observed up to 2 K, though the carrier density does not change significantly. We present specific heat data showing that a stronger ...

XC cells originally derived from the tumor of a rat previously inoculated with the Prague strain of Rous sarcoma virus were used to induce tumors in chickens surgically thymectomized or bursectomized in the newly hatched period. Thymectomized chickens had a significantly higher incidence of tumors, larger tumors, and a higher tumor mortality, compared with control chickens, when both groups wer...

Convergence problems of meta-GGA (generalized gradient approximation) XC (exchange and correlation) functionals containing a self-interaction correction term are traced back to a singularity of the latter that occurs at critical points of the electron density. This is demonstrated for the bond critical point of equilibrium and stretched H2. A simple remedy is suggested that cures meta-XC functi...

∂tc+ λ c+ u ∂xc− κ ∂ xc = q + ∂xf + ∂ xg . At the grid points the extremely high order of approximation for the numerical solutions is such that if loss of accuracy is to be avoided then interpolation must use values extending beyond the local 3 by 2 computational module. Illustrative examples show that reasonable accuracy is possible with extremely long time steps on sparse non-uniform, moving...
