Using Monte Carlo techniques, the critical Binder cumulant U∗ of isotropic nearest–neighbour Ising models on square and triangular lattices is studied. For rectangular shapes, employing periodic boundary conditions, U∗ is found to show the same dependence on the aspect ratio for both lattice types. Similarly, applying free boundary conditions for systems with square as well as circular shapes f...

where a(x, t) is some scalar quantity and u is the velocity at which it is advected (u > 0 advects to the right). The solution to Eq. 1 is to simply take the initial data, a(x, t = 0), and displace it to the right at a speed u. The shape of the initial data is preserved in the advection. Many hyperbolic systems of PDEs, e.g. the equations of hydrodynamics, can be written in a form that looks li...

conclusions extracts of u. dioica showed significant antibacterial effect against some clinically important pathogenic bacteria. based on the obtained results it can be concluded that u. dioica is useful as antibacterial and bactericidal agent in treating infectious diseases. materials and methods hydroalcoholic extracts from aerial parts were prepared using aqueous solution of ethanol and meth...

ABSTRACT In the smut fungi, few features are available for use as taxonomic criteria (spore size, shape, morphology, germination type, and host range). DNA-based molecular techniques are useful in expanding the traits considered in determining relationships among these fungi. We examined the phylogenetic relationships among seven species of Ustilago (U. avenae, U. bullata, U. hordei, U. kolleri...

We consider a system of two porous medium equations defined on two different components of the real line, which are connected by the nonlinear contact condition ux = vx , v = ψ(u) on the contact line S. First we prove existence and uniqueness of a solution (u, v) on a bounded domain. Furthermore, we are interested in the behaviour of the interface of the porous medium equation when it crosses t...

The shape-from-shading (SFS) equation relating u(y, r), the unknown (angular) height of a surface, to I(y, r), the known synthetic aperture radar (SAR) intensity data from the surface, is

We show that quantile regression is better than ordinary-least-squares (OLS) in forecasting profitability for a range of measures following the conventional setup accounting literature, including mean absolute forecast error (MAFE) evaluation criterion. Moreover, we perform both simulated-data and an archival-data analysis to examine how performance against OLS changes with shape distribution. ...

We examine the effect of rainfall on agricultural output and democratization in world’s most countries. As economics literature, we find that relationship between has an inverted U-shape, as agriculture is harmed by both droughts very wet conditions. also to be transitory. The U-shaped short run, this persists long run. Hence democratic transitions outlast (transitory) shocks started process. c...

We obtain a characterization of quantum shape-phase transitions in the terms of complexity measures in the two-dimensional limit of the vibron model based on the spectrum generating algebra U(3). Complexity measures (in terms of the Rényi entropies) have been calculated for different values of the control parameter for the ground state of this model giving sharp signatures of the quantum shape-...
