Sound waves are converted into electric signals by hair bundles(also known as stereocilia)in the cochlear hair ***,a cluster of actin protrusions at the apical surface of hair cells,are organized into rows of graded height(Figure 1).Mechanical force induced by sound waves leads to stereocilia deflection towards the tallest row and subsequent activation of mechanoelectrical transducer channels at the tips of the shorter rows,thus achieving mechanoelectrical transduction(Gillespie and Muller,2009).Such a staircase-like architecture is essential for auditory perception as manifested by severe deafness caused by genetic mutations that disrupt stereocilia morphology(Barr-Gillespie,2015).However,little is known about how this planar asymmetry of stereocilia is achieved.

Traveling wave solutions for a diffusive predator-prey model with predator saturation and competition

引用

International Journal of Biomathematics 2017年第6期10卷 231-253页

作者： lin zhu shi-Liang Wu School of Mathematics and Statistics Xidian University Xi'an Shanxi 710071 P. R. China

The purpose of this paper is to study the traveling wave solutions of a diffusive predator- prey model with predator saturation and competition functional response. The system admits three equilibria： a zero equilibrium E0, a boundary equilibrium E1 and a posi- tive equilibrium E. under some conditions. We establish the existence of two types of traveling wave solutions which connect E0 and E. and E1 and E., respectively. Our main arguments are based on a simplified shooting method, a sandwich method and constructions of appropriate Lyapunov functions. Our particular interest is to investi- gate the oscillation of both types of traveling wave solutions when they approach the positive equilibrium.

X（1835）： A Possible Baryonium？

引用

Communications in Theoretical Physics 2006年第2X期46卷 291-293页

作者： zhu shi-lin GAO Chong-Shou Department of Physics Peking University Beijing 100871 China Research Center for Nuclear Physics Osaka University Japan

We point out that the large pp^- coupling of X（1835） and the suppression of the three-body strange final states strongly indicate that X（1835） may be a pp^- baryonium. We also point out that the branching ratio of X（1835） →ηππ should be bigger than that of X（1835） →η′ππ. We suggest BES search X（1835） in the ηππ channel Finally, X（1835） may be used a tetraquark generator if X（1835） is really established as a baryonium state.
