A neutrally buoyant particle in pipe flow is known to undergo a radial migration for finite Reynolds number flows. This effect was first observed by Segré and Silberberg (1962), who noted a radial equilibrium position at a radius r = 0.6R in a pipe of radius R, in conditions of finite but low Re. These results have been extended to show that the equilibrium position of the particles is moved to...

Mutations at multiple sites within the simian virus 40 (SV40) early region yield large T antigens which interfere trans dominantly with the replicative activities of wild-type T antigen. A series of experiments were conducted to study possible mechanisms of interference with SV40 DNA replication caused by these mutant T antigens. First, the levels of wild-type T antigen expression in cells cotr...

OBJECTIVE To assess the effect of a tackling task replicating the force magnitudes and directions seen in a competitive game or training session, on a players shoulder joint position sense. DESIGN Repeated measures design. SETTING Field based. PARTICIPANTS Nineteen, senior, male, semi-professional rugby union players. MAIN OUTCOME MEASURES Two criterion angles of 45° and 20° off maximal...

Chinese tone sandhi systems are often classified as left-dominant or right-dominant depending on the position of the syllable retaining the citation tone. An asymmetry exists between the two types of systems: left-dominant sandhi often involves rightward extension of the initial tone to the entire sandhi domain; right-dominant sandhi, however, often involves default insertion and paradigmatic n...

This study mapped the development of proprioception in healthy, typically developing children by objectively measuring forearm position sense acuity. We assessed position sense acuity in a cross-sectional sample of 308 children (5-17 years old; M/F = 127/181) and a reference group of 26 healthy adults (18-25 years old; M/F = 12/14) using a body-scalable bimanual manipulandum that allowed forear...
