We studied the effects of the lower leg bi-articular muscle in vertebrates in jumping. We used the proposed Jumping Jack model in computer simulation to analyze the impact of bi-articular muscle on postural jumping stability, energy transition caused by postural change, and the relationship between the ground reaction force and the center of gravity. We made a trial model and measured the jumpi...

BACKGROUND Little is known about the characteristics of people who die by jumping from different locations (e.g. bridges, buildings) and the factors that might influence the effectiveness of suicide prevention measures at such sites. METHODS We collected data on suicides by jumping (n = 134) between 1994 and 2003 in Bristol, UK, an area that includes the Clifton Suspension Bridge, a site reno...

M. Saito [S] proved that the jumping numbers of a hyperplane arrangement depend only on the combinatorics of the arrangement. However, a formula in terms of the combinatorial data was still missing. In this note, we give a formula and a different proof of the fact that the jumping numbers of a hyperplane arrangement depend only on the combinatorics. We also give a combinatorial formula for part...

The importance of jumping ability in basketball is well known, but there is an evident lack of studies that have examined different jumping testing protocols in basketball players at advanced levels. The aim of this study was to assess the applicability of different tests of jumping capacity in identifying differences between (i) playing position and (ii) competitive levels of professional play...

In this paper, the robust Kalman filtering problem for uncertain discretetime linear systems with hlarkovian jumping parameters is addressed. It is assumed that the information about the jumping parameters is available, and the uncertainties are formulated by linear fractional transformation. We propose two methods for designing Markovian jumping filters so that the covariance of estimation err...

Many tiny robots have developed which walk in smooth surface but the problem face in complex terrain. Some wheel based robot move in flat surface only. In this paper, we studied some bio-inspired jumping robots like Grillo, MiniWhegs, MSU jumper, EPFL. Because Jumping is used by small animals in nature, rough terrain and cluttered environment. These robots use energy store and release mechanism...

in the present study, interactive effects of d1 and d2 dopamine receptors antagonists and different periods of lithium pretreatment on morphine dependence in mice have been investigated. this study was designed to investigate whether the hypothesis that lithium and dopaminergic mechanisms via their effects on phosphoinositide pathways and calcium flux could influence morphine withdrawal respons...

Properties of sport surfaces influence the occurrence of injuries and the performance of equine athletes. The sports governing body seeks to develop standards for safety and performance of show jumping surfaces. Limited information is available to guide this process. Objective methods are warranted in order to define surface properties that can be associated to injury and performance data. Desc...

Jumping: There are a limited number of studies available evaluating the efficiency of interventions aiming to reduce numbers of suicides by jumping. They are limited to sites that have over the years acquired a status of iconic suicide ‘hot-spots’. There are no studies reporting on the efficiency of such interventions in reducing suicide attempts, possibly because suicide by jumping is consider...
