objectives: cerebral hemispheres functioning have been found to be abnormal in children with asd. the role of lateralization in implicit and explicit motor learning has received little attention in asd researches. the main goal of this study is investigating the differences between two hands implicit and explicit motor learning in children with asd and typical matched group. methods: in the pre...

introduction: the aim of this study was to assess of both implicit and explicit motor sequence learning in children with attention deficit hyper activity disorder (adhd) and typical peers , by serial reaction time task. materials and methods: the sample size for each group was 12. the study sample was included 24 children with adhd, in explicit learning group and implicit learning group.  and 2...

We provide explicit conditions for a polynomial f of degree 2d to be a sum of squares (s.o.s.), stated only in terms of the coefficients of f , i.e. with no lifting. All conditions are simple and provide an explicit description of a convex polyhedral subcone of the cone of s.o.s. polynomials of degree at most 2d. We also provide a simple condition to ensure that f is s.o.s., possibly modulo a c...

We construct and analyze combinations of rational implicit and explicit multistep methods for nonlinear parabolic equations. The resulting schemes are linearly implicit and include as particular cases implicit-explicit multistep schemes as well as the combination of implicit Runge-Kutta schemes and extrapolation. An optimal condition for the stability constant is derived under which the schemes...

In this note, based on a control Lyapunov function approach, an integrated design of switching laws and feedback controllers for uncertain switched nonlinear control systems with two modes is discussed. A sufficient condition for the existence of globally asymptotically stabilizing state feedback laws (switching laws  controllers) is derived. Moreover, an explicit rule for constructing switchi...

using the group inverse, an explicit solution to a symmetric singular system is described. The general explicit solution is derived when the symmetric singular system satisfies the regularity condition. Certain special properties of these singular systems are presented. Finally, a symmetric balanced realization is obtained from an equivalent standard control system. @ 2002 Elsevier Science Ltd....

Data rei cation normally involves the explicit positing of an abstraction function with certain properties. However, the condition for one de nition to reify another only requires that a function with such properties should exist. This suggests that it may be possible to carry through a data rei cation without giving an explicit de nition of the abstraction function at all. This paper explores ...

Using motivational intensity theory as a framework, three experiments examined how implicit self-focus (manipulated with masked first-name priming) and explicit self-focus (manipulated with a large mirror) influence effort-related cardiovascular activity, particularly systolic blood pressure reactivity. Theories of self-focused attention suggest that both implicit and explicit self-focus bring ...

We present a real symmetric tridiagonalmatrix of order nwhose eigenvalues are {2k}n−1 k=0 which also satisfies the additional condition that its leading principle submatrix has a uniformly interlaced spectrum, {2l + 1}n−2 l=0 . Thematrix entries are explicit functions of the size n, and so the matrix can be used as a test matrix for eigenproblems, both forward and inverse. An explicit solution ...

This paper is devoted to the analysis of a numerical scheme for the coagulation and fragmentation equation. A time explicit finite volume scheme is developed, based on a conservative formulation of the equation. It is shown to converge under a stability condition on the time step, while a first order rate of convergence is established and an explicit error estimate is given. Finally, several nu...
