In this paper we introduce a system of nonlinear ordinary differential equations which in a particular case reduces to Volterra’s system. We found in two simplest cases the complete sets of the integrals of motion using Nambu–Poisson reformulation of the Hamiltonian dynamics. In these cases we have solved the systems by quadratures.

We present an overview of existing methods to generate pseudorandom numbers from a nonhomogeneous Poisson process. We start with various definitions of the nonhomogeneous Poisson process, present theoretical results (sometimes with a proof) that form the basis of existing generation algorithms, and provide algorithm listings. Whenever available, we also provide links to sources containing compu...

Stochastic point sets are considered that display a diffraction spectrum of mixed type, with special emphasis on explicitly computable cases together with a unified approach of reasonable generality. Several pairs of autocorrelation and diffraction measures are discussed which show a duality structure that may be viewed as analogues of the Poisson summation formula for lattice Dirac combs.

We derive the ‘exact’ Newtonian limit of general relativity with a positive cosmological constant Λ. We point out that in contrast to the case with Λ ≤ 0, the presence of a positive Λ in Einsteins’s equations enforces, via the condition |Φ| 1, on the potential Φ, a range Rmax(Λ) r Rmin(Λ), within which the Newtonian limit is valid. It also leads to the existence of a maximum mass, Mmax(Λ). As a...

As know, a ballistic MOS-Like carbon nanotube FET can be simulated by using a self-consistent procedure between the charge and the Poisson equations. Because of the integral form of the charge equation, this model cannot be implemented in the commercially available circuit simulators, such as SPICE. In this paper, we propose an analytical solution for estimating the charge equation, so that the...

We present an approach for solving the Boltzmann equation based on the explicit construction of the Green’s functions. The Green’s function approach has been useful for the study of nonlinear interior waves and the boundary waves. In this Part I we study the Green’s functions for the initial and initial-boundary value problems. In the forthcoming Part II, we will study the general solutions of ...

We show the existing solution of Poisson-Boltzmann equation (PBE) to violate charge conservation principle, and then derive the correct formula for charge density distribution (ρe) in a fluid. We replaced unphysical old boundary conditions with some conditions that have never been used. Our result demonstrates that PBE cannot explain the formation of ‘Electric Double Layer’ (EDL); it follows th...

We set limits on the magnetic moment and charge radius of the tau neutrino by examining an extra contribution to the electroweak process e+e− → ννγ using VENUS, TOPAZ and AMY results. We find that κ(ντ ) < 9.1 × 10−6 (i.e. μ(ντ ) < 9.1 × 10μB , μB = e/2me) and 〈r2〉 < 3.1 × 10−31cm2 with Poisson statistics by combining their results. Whereas, similar to this method, with the Unified Approach we ...

In a spherical-harmonics expansion formulation of the semi-classical Boltzmann transport equation (BTE) the influence of surface-scattering mechanisms on mobility are investigated, accounting for both global and local scattering mechanisms, with reference to holes in silicon. The analysis successfully reproduces the experimental data.
