purpose : to demonstrate visual evoked potential (vep) changes in multiple sclerosis (ms) disease methods : a case series study of vep changes in forty-nine patients with definite, probable and possible diagnoses of ms referred to electrophysiology ward from january 2002 to december 2005. pattern vep was done for those with good visual acuity (va), and flash vep was done for those who did not h...

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 ...

We present an explicit method to evaluate the nonnegativity of order 3 Matrix exponential functions.

The basic ideas of semi-implicit time differencing are reviewed, including analytical results not widely referenced in the meteorological literature. It is shown that solving the resulting implicit equations by simple fixed-point iteration requires a relatively small time step to guarantee convergence, thus defeating the purpose of the semiimplicit method. In contrast, classical iteration metho...

In this work, we discuss a family of parallel implicit time integrators for multi-core and potentially multinode or multi-gpgpu systems. The method is an extension of Revisionist Integral Deferred Correction (RIDC) by Christlieb, Macdonald and Ong (SISC-2010) which constructed parallel explicit time integrators. The key idea is to re-write the defect correction framework so that, after initial ...

Implicit pressure-explicit saturation method (IMPES) is widely used in oil reservoir simulation to study the multiphase flow in porous media. This method has no complexity compared to the fully implicit method, although both of them are based on the finite difference technique. Water coning is one the most important phenomenon that affects the oil production from oil reservoirs having a water d...

the aim of this study was to evaluate the effect of handedness and two practice types (explicit vs. implicit) on motor sequence learning. 60 girls (age range of 14 – 17 years old) were randomly assigned to four groups according to their handedness: right–handed-explicit, right–handed–implicit, left–handed-explicit, and left–handed-implicit. participants’ task was accuracy and time of sequential...

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...
