Objectives: Each step during gait requires different attention demands that will affect muscles activity. The study of changes in the timing and intensity of the muscles activity in walking with dual task has received less attention from researchers. The purpose of this study was to evaluate changes in electromyography patterns of gait with cognitive dual tasks in balance impaired elderly. M...

The relationship between topography, land use, and topsoil moisture storage is investigated for a small catchment with undulating deep loess hilslopes in the south of the Netherlands. For a period of 10 months, soil moisture profiles have been measured weekly at 15 locations throughout the catchment. A Generalized Additive Model was employed to find relationships between the various factors inf...

Background and Objective: In the recent decade, critical condition of particulate matters (PMs) concentration is considered as one of the most important issues in Tehran megacity. Due to sparse spatial distribution of air quality monitoring stations and economic considerations, researchers proposed remote sensing technique as a fast and economical way to obtain complete spatial and temporal cov...

Aims & Backgrounds: The present study analyzes the spatial location of sports facilities and assessing the access to sports centers according to their spatial distribution pattern at the level of communication networks in Garmsar County. The main purpose is to identify the distribution and distribution status of sports applications in the city and determine the shortcomings and needs. Methodolo...

Protrusion formation is the first step that precedes cell movement of motile cells. Spatial control of actin polymerization is necessary to achieve directional protrusion during cell migration. Here we show that the spatial coordinators p190RhoGEF and p190RhoGAP regulate actin polymerization during leading edge protrusions by regulating the actin barbed end distribution and amplitude. The distr...

Spatial data balancing distribution can evidently improve the performance of parallel spatial database in shared nothing parallel architecture. Considering spatial locality and unstructured variable length characteristics of spatial data, this paper proposes a dynamic spatial data balancing distribution method under shared nothing parallel database environment. By using Hilbert ordering code to...
