Physical Review B 2006年 第5期73卷 054109-054109页
作者: Aleksandar Donev Joshua Burton Frank H. Stillinger Salvatore Torquato Program in Applied and Computational Mathematics Princeton University Princeton New Jersey 08544 USA PRISM Princeton University Princeton New Jersey 08544 USA Department of Physics Princeton University Princeton New Jersey 08544 USA Department of Chemistry Princeton University Princeton New Jersey 08544 USA
Previous Monte Carlo investigations by Wojciechowski et al. have found two unusual phases in two-dimensional systems of anisotropic hard particles: a tetratic phase of fourfold symmetry for hard squares [Comput. Meth...

Physical Review E 2006年 第1期74卷 010901(R)-010901(R)页
作者: Raymond E. Goldstein Alain Goriely Department of Physics University of Arizona Tucson Arizona 85721 USA BIO5 Institute University of Arizona Tucson Arizona 85721 USA Program in Applied Mathematics University of Arizona Tucson Arizona 85721 USA Department of Mathematics University of Arizona Tucson Arizona 85721 USA
The equilibrium shapes of biological structures as diverse as plant tendrils and bacterial filaments can be altered by externally imposed stresses of sufficient duration. We study the simplest model for this morphoela... 详细信息

Physical Review E 2006年 第3期73卷 030901(R)-030901(R)页
作者: Luis Cisneros Christopher Dombrowski Raymond E. Goldstein John O. Kessler Department of Physics University of Arizona Tucson Arizona 85721 USA Program in Applied Mathematics University of Arizona Tucson Arizona 85721 USA BIO5 Institute University of Arizona Tucson Arizona 85721 USA
Recent experiments have shown large-scale dynamic coherence in suspensions of the bacterium B. subtilis, characterized by quorum polarity, collective parallel swimming of cells. To probe mechanisms leading to this, we... 详细信息

Mechanism of enhanced broadening of the ionization level of Li outside transition metal surfaces
收藏 引用
Physical Review B 2006年 第11期74卷 115109-115109页
作者: Keith Niedfeldt Peter Nordlander Emily A. Carter Department of Mechanical and Aerospace Engineering and Program in Applied and Computational Mathematics Princeton University Princeton New Jersey 08544-5263 USA Department of Physics and Astronomy M.S. 61 Rice University P.O. Box 1892 6100 South Main Street Houston Texas 77251-1892 USA
We show that the d-band of a transition metal surface induces intra-atomic hybridization of an atom in its vicinity. It is demonstrated that such hybridization can have a profound influence on the resonance width and ...

Physical Review E 2006年 第4期74卷 041911-041911页
作者: Tobias Munk Oskar Hallatschek Chris H. Wiggins Erwin Frey Arnold Sommerfeld Center and Center for NanoScience Ludwig-Maximilians-Universität München Theresienstraße 37 80333 München Germany Lyman Laboratory of Physics Harvard University Cambridge Massachusetts 02138 USA Department of Applied Physics and Applied Mathematics and Center for Computational Biology and Bioinformatics Columbia University 500 West 120th Street New York New York 10027 USA
We present a method to investigate the dynamics of a single semiflexible polymer, subject to anisotropic friction in a viscous fluid. In contrast to previous approaches, we do not rely on a discrete bead-rod model, bu... 详细信息
