An approximate method for calculating drift velocity and other kinetic coefficients of heavy ions
in a light gas is generalized to gaseous mixtures. Obtained equations are used to calculate the mobilities of
and ions, as well as rate constants for inelastic ion–molecule processes with these ions in helium with
small additions of O2 under an electric field. Calculated ...

The Smirnov method for obtaining the drift velocity of heavy ions in a light gas is generalized to
calculate the rate coefficients of threshold ion–molecule reactions. Different versions of this simple
method are used to calculate the mobility and rate coefficients for O4−,O2−, and NO− ions moving
through helium under the influence of an electric field. Calculated results ...

Taking into account the variation in the parameters of SPICE models of semiconductor components in the circuit modeling of electronic components is necessary for a more accurate assessment of the limits of their operability during the design of electronic equipment. This is especially important for equipment designed to operate in conditions other than normal or ...

The present paper bridges mathematical modeling and wind resource assessment (WRA). Sensitivity analysis (SA) links portions of output variance to the variance in each input variable. Global SA (GSA) explores inputs globally. One-at-a-time SA is dominating in WRA, while GSA is often overlooked. Compared to traditional methods, GSA offers potential improvement by the means of ...

Using an approximate approach that is valid for a large ratio of the ion mass to the mass of the neutral
particle, the mobility of O2+, N2+, O2-, and O4- ions was calculated in helium and good agreement was
obtained with the available results of Monte Carlo calculations and experimental data at high values of the
reduced electric ...

The kinetics of electrons and negative ions was numerically studied under the conditions, which are typical for multi-pulsed guided ionization waves in He flows ejected into ambient air. It was shown that, in He with a small admixture of O2 or air, O2- ions formed due to three-body electron attachment in the discharge afterglow are rapidly ...

The population annealing method is a promising approach for large-scale simulations because it is potentially scalable on any parallel architecture. We present an implementation of the algorithm on a hybrid program architecture combining CUDA and MPI. The problem is to keep all general-purpose graphics processing unit devices as busy as possible by efficiently redistributing replicas. ...

Credit rating agencies evaluate corporate risks and assign ratings to companies. Each rating grade corresponds to certain boundaries of default probability. KMV is a popular model to assess the default probability of a company. In this paper, a method to predict the default probability of a company is proposed. This method is based on the ...

The study considers corporate inversion, also known as tax inversion, which involves companies to move their operations overseas in order to avoid tax burden in the domestic country. Although the following strategy gains popularity among corporate managers, experts emphasize its’ controversial and risky nature (Lusch et al., 2016). The aim of this paper is twofold. First, we ...

In this paper we study optimal stopping problems for nonlinear Markov processes driven by a McKean-Vlasov SDE and aim at solving them numerically by Monte Carlo. To this end we propose a novel regression algorithm based on the corresponding particle system and prove its convergence. The proof of convergence is based on perturbation analysis of ...

Atomistic aspects of the structural organization, dynamics, and functioning of hydrated lipid bilayers - model cell membranes - are primarily governed by the fine balance of intermolecular interactions between all constituents of these systems. Besides the hydrophobic effect, which shapes the overall skeleton of lipid membranes, very important contribution to their behavior is made by ...
