Abstract In previous publications, it was argued that because energy and matter are aligned in the thin increment of present time for an observer, spacetime should must have surface tension. this paper, we review how to apply 4-dimensional continuum mechanics with imaginary coordinates derive a mechanical model Then, continue development, discuss concept preferred curvature from physical chemis...
In this paper, a new type of steel-concrete composite member, concrete-filled core steel tube with outer angle steel plank reinforced concrete stub column, is proposed and a series of nonlinear 3D(three-dimensional) full-range numerical calculations under axial compression are carried out, some important factors are analyzed, such as the strength of the concrete, the steel tube and the angle st...
In order to calculate ion currents through solid-state nanopore transistors realistically, we propose a computational model based on the Poisson-Nernst-Plank equation. In the present model, we determine the surface charge density locally on the nanopore by imposing consistency between the ion distribution and the chemical reaction at the surface. The model can consider a non-uniform influence b...
In [BL] in relation to the unsolved Bang’s plank problem (1951) we obtained a lower bound for the sum of relevant measures of cylinders covering a given d-dimensional convex body. In this paper we provide the packing counterpart of these estimates. We also extend bounds to the case of r-fold covering and packing and show a packing analog of Falconer’s results ([Fa]).
This is a revised variant of my preprint: Max-Plank Institut fuer Mathematik, Bonn, 2001, No 16. Foreword This is the first part of the detailed version of my work “On linear forms with coefficients in Nζ(1 + N),” [11]. The goal of this work is to give a complete proof of the following theorem. Theorem. Let

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
