The asymptotic solution for the Painleve-2 equation with small parameter is considered. The solution has algebraic behavior before point t∗ and fast oscillating behavior after the point t∗. In the transition layer the behavior of the asymptotic solution is more complicated. The leading term of the asymptotics satisfies the Painleve-1 equation and some elliptic equation with constant coefficient...
Abstract. This paper is concerned with the numerical approximation of stochastic ordinary differential equations, which satisfy a global monotonicity condition. This condition includes several equations with super-linearly growing drift and diffusion coefficient functions such as the stochastic Ginzburg-Landau equation and the 3/2-volatility model from mathematical finance. Our analysis of the ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2015209409 DESCRIPTION An 88-year-old woman presented with sudden onset sharp upper abdominal pain associated with anorexia, vomiting and weight loss. Examination revealed a tender palpable mass in the epigastrium without any abnormal blood tests. A CT scan showed a 12 cm cystic...
In this paper, we introduce the concept of ordinary smooth topology on a set X by considering the gradation of openness of ordinary subsets of X . And we obtain the result [Corollary 2.13] : An ordinary smooth topology is fully determined its decomposition in classical topologies. Also we introduce the notion of ordinary smooth [resp. strong and weak] continuity and study some its properties. A...
My typical working week shows just how varied mental health nursing can be. As a GP liaison nurse specialising in mental health, I work from the surgery, hospitals, clinics and other agencies, depending on where the surgery's patients are referred.
Background and Aim: Carriage of backpack sprayers is an inevitable part of agricultural operations that increases the risk of injury along with undesirable changes in walking mechanics. The purpose of this study is to formulate the muscle moment changes in the hip, knee and ankle for the backpack sprayer operator body. Methods: In this study, a seven-link sprayer operator model is designed and...
We discuss a dynamic procedure that makes fractional derivatives emerge in the time asymptotic limit of non-Poisson processes. We find that two-state fluctuations, with an inverse power-law distribution of waiting times, finite first moment, and divergent second moment, namely, with the power index mu in the interval 2<mu<3 , yield a generalized master equation equivalent to the sum of an ordin...
We consider a subset of Markov fluid models where the discrete background process is a Population Continuous Time Markov Chain (PCTMC) – a Markov process capturing interactions between large groups of identically behaved components. We allow the transition and fluid evolution rates to depend on the fluid level. Additionally, we include time-inhomogeneous rate parameters, which can be used to in...
In solving a system of ordinary differential equations by an interval method the approximate solution at any considered moment of time t represents a set (called interval) containing the exact solution at the moment t. The intervals determining the solution of a system are often expanded in the course of time irrespective of the method and step used. The phenomenon of interval expansion, called...
