A good understanding of the control processes used to maintain stability in functional movements is essential for clinicians who attempt to treat or manage musculoskeletal pain problems. There is evidence of muscle dysfunction related to the control of the movement system. There is a clear link between reduced proprioceptive input, altered slow motor unit recruitment and the development of chro...

A model to predict the effect of global and local conformability on grasp static stability is presented. Conformability is defined as the geometric similarity between a workpiece and the smallest polyhedron fit over all contacts. Two conformability metrics, C1 and C2, that quantify global and local conformability, respectively, are introduced. All stiffness components, including workpiece bulk ...

This paper explores the stability of a class of feedback fuzzy systems. The class consists of generalized additive fuzzy systems that compute a system output as a convex sum of linear operators. Continuous versions of these systems are globally asymptotically stable if all rule matrices are stable (negative definite). So local rule stability leads to global system stability. This relationship b...

Background There is an increasing trend of international migration of health professionals from low- and middle- income countries to high-income countries as well as across middle-income countries. The WHO Global Code of Practice on the International Recruitment of Health Personnel was created to better address health workforce development and the ethical conduct of international recruitment. T...

We consider the global optimization of a nonsmooth (nondifferentiable) nonconvex real function. We introduce a variable metric descent method adapted to nonsmooth situations, which is modified by the incorporation of suitable random perturbations. Convergence to a global minimum is established and a simple method for the generation of suitable perturbations is introduced. An algorithm is propos...

Design/methodology/approach Granger causality test GMM coefficient matrix methodologies were used. Findings There sustained increase eNaira first six weeks after adoption. Local exceeded cryptocurrency. The south-east re...

The paper dwells on the problems of stability of dynamical systems on a time scale. The paper is divided into the following sections: local existence and uniqueness, dynamic inequalities, existence of extremal solutions, comparison results, linear variation of parameters, nonlinear variation of parameters, global existence and stability, comparison theorems, stability criteria, etc.
