Analysis of the Oscillating Motion of a Solid Body on Vibrating Bearers

Machines, 2019
This article considers the oscillation of a solid body on kinematic foundations, the main elements of which are rolling bearers bounded by high-order surfaces of rotation at horizontal displacement of the foundation.

Equilibrium and Stability of Entropy Operator Model for Migratory Interaction of Regional Systems

Mathematics, 2019
In this paper, we develop a dynamic model for migratory interaction of regional systems that is based on an entropy operator. Next, we study the properties of this operator and establish the existence of a unique singular point in the dynamic entropy ...

SINGULAR POINTS FOR THE SUM OF A SERIES OF EXPONENTIAL MONOMIALS

Проблемы анализа, 2018
A problem of distribution of singular points for sums of series of exponential monomials on the boundary of its convergence domain is studied. The influence of a multiple sequence Λ = {λk, nk}_(∞;k=1) of the series in the presence of singular points on ...

Properties of the resolvent of singular q-Dirac operators

Electronic Journal of Differential Equations, 2020
In this article, we investigate the resolvent operator of a singular q-Dirac system. We obtain an integral representations for the resolvent of this system, in terms of the spectral function.

Study of Stability of Non-linear Model with Hyperbolic Secant Function [PDF]

مجلة التربية والعلم, 2019
We study a new definition of a non-linear model of time series with hyperbolic secant function in a discrete time. The suggested model consist of two parts the first part is (linear) and the second part is (non-linear) which contains the hyperbolic ...

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
