The critical points of the two-layer Ising and Potts models for square lattice have been calculated with high precision using probabilistic cellular automata (PCA) with Glauber alghorithm. The critical temperature is calculated for the isotropic and symmetric case (Kx=Ky=Kz=K), where Kx and Ky are the nearest-neighbor interactions within each layer in the x and y directions, respectively, and K...
Introduct ion Investigations of former KZ-prisoners report of extensive physical and psychological sequences. Some studies have focused on the somatic consequences of hunger dvstrophy (Herman and Thygcsen 1954, Thygcsen et al 1970) and the KZ-syndrome is seen as an organic damage also affecting the brain (Nielsen 1986). Others (e.g. Chodoft 1982) stress that the massive emotional and physical t...
The three-dimensional band structure and superconducting gap of Ba0.6K0.4Fe2As2 are studied with angle-resolved photoemission spectroscopy. In contrast with previous results, we have identified three holelike Fermi surface sheets near the zone center with sizable out-of-plane or kz dispersion. The superconducting gap on certain Fermi surface sheets shows significant kz dependence. Moreover, the...
Introduction In principle, two different approaches are reported to diminish wave propagation effects, and thus, improve B1 homogeneity with parallel transmission. The first approach is given by "basic" RF shimming, adjusting amplitude and phase of the different transmit channels to obtain a homogeneous B1 distribution [1]. The second approach is given by "tailored" RF shimming, i.e., multidime...
We present a systematic study of the dynamical scaling process leading to the establishment of the Kolmogorov-Zakharov (KZ) spectrum in weak three-wave turbulence. In the finite-capacity case, in which the transient spectrum reaches infinite frequency in finite time, the dynamical scaling exponent is anomalous in the sense that it cannot be determined from dimensional considerations. As a conse...
We present a proof for certain cases of extended Borsuk-Ulam conjectures by Baum, D ‘ abrowski, and Hajac. When a unital C-algebra A admits a free action of Z/kZ, k ≥ 2, we show that there is no equivariant map from A to the C-algebraic join of A and the compact “quantum” group C(Z/kZ). This also resolves D ‘ abrowski’s conjecture on unreduced suspensions of C-algebras and has implications in t...
Financing strategy in corporations is one of the most important subject matters among accounting and finance scholars. Investment in companies to increase profitability is one of the important purposes of financing activities. Different methods for execution of financing activities include: Internal finance, external finance and combination of these two. The problem is that whether there is...
The Kibble-Zurek (KZ) mechanism is a universal framework that can in principle describe nonequilibrium phase transition phenomena any system with the required symmetry properties. However, conflicting phenomenon termed anti-KZ behavior has been reported study of ferroelectric transitions, which slower driving results more topological defects [S. M. Griffin et al., Phys. Rev. X 2, 041022 (2012)]...
