Optimized Interactions for Targeted Self-Assembly: Application to a Honeycomb Lattice
收藏 引用
Physical Review Letters 2005年 第22期95卷 228301-228301页
作者: Mikael C. Rechtsman Frank H. Stillinger Salvatore Torquato Department of Physics Princeton University Princeton New Jersey 08544 USA Department of Chemistry Princeton University Princeton New Jersey 08544 USA Program in Applied and Computational Mathematics and PRISM Princeton University Princeton New Jersey 08544 USA
We devise an inverse statistical-mechanical methodology to find optimized interaction potentials that lead spontaneously to a target many-particle configuration. Target structures can possess varying degrees of disord... 详细信息

Physical Review E 2005年 第3期71卷 031915-031915页
作者: György Károlyi []Center for Applied Mathematics and Computational Physics and Department of Structural Mechanics Budapest University of Technology and Economics M?egyetem rkp. 3 H-1111 Budapest Hungary
The growth dynamics of filamentary microbial colonies is investigated. Fractality of the fungal or actinomycetes colonies is shown both theoretically and in numerical experiments to play an important role. The growth ... 详细信息

9th Annual International Conference on Research in computational Molecular Biology, RECOMB 2005
作者: Middendorf, Manuel Kundaje, Anshul Shah, Mihir Freund, Yoav Wiggins, Chris H. Leslie, Christina Department of Physics Columbia University New York NY 10027 Department of Computer Science Columbia University New York NY 10027 Department of Applied Mathematics Columbia University New York NY 10027 Center for Computational Biology and Bioinformatics Columbia University New York NY 10027 Center for Computational Learning Systems Columbia University New York NY 10027
We present MEDUSA, an integrative method for learning motif models of transcription factor binding sites by incorporating promoter sequence and gene expression data. We use a modern large-margin machine learning appro... 详细信息

Coiling, Entrainment, and Hydrodynamic Coupling of Decelerated Fluid Jets
收藏 引用
Physical Review Letters 2005年 第18期95卷 184501-184501页
作者: Christopher Dombrowski Braddon Lewellyn Adriana I. Pesci Juan M. Restrepo John O. Kessler Raymond E. Goldstein Department of Physics 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
From algal suspensions to magma upwellings, one finds jets which exhibit complex symmetry-breaking instabilities as they are decelerated by their surroundings. We consider here a model system—a saline jet descending ... 详细信息

Physical Review B 2005年 第1期72卷 012401-012401页
作者: A. Vernes P. Weinberger L. Szunyogh Department of Theoretical Physics and Center for Applied Mathematics and Computational Physics Budapest University of Technology and Economics Budafoki út 8 H-1521 Budapest Hungary and Center for Computational Materials Science Gumpendorferstrasse 1a A-1060 Wien Austria
Current-induced switching in Py∕Cu∕Py spin valves with the Cu spacer thickness varying between 20 and 30 monolayers is described theoretically in terms of a multiscale approach based on ab initio calculations using ...

Pair correlation function characteristics of nearly jammed disordered and ordered hard-sphere packings
收藏 引用
Physical Review E 2005年 第1期71卷 011105-011105页
作者: Aleksandar Donev Salvatore Torquato Frank H. Stillinger Program in Applied and Computational Mathematics Princeton University Princeton New Jersey 08544 USA PRISM Princeton University Princeton New Jersey 08544 USA Department of Chemistry Princeton University Princeton New Jersey 08544 USA
We study the approach to jamming in hard-sphere packings and, in particular, the pair correlation function g2(r) around contact, both theoretically and computationally. Our computational data unambiguously separate th... 详细信息

Unexpected Density Fluctuations in Jammed Disordered Sphere Packings
收藏 引用
Physical Review Letters 2005年 第9期95卷 090604-090604页
作者: Aleksandar Donev 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 Chemistry Princeton University Princeton New Jersey 08544 USA
We computationally study jammed disordered hard-sphere packings as large as a million particles. We show that the packings are saturated and hyperuniform, i.e., that local density fluctuations grow only as a logarithm... 详细信息

Physical Review Letters 2005年 第25期95卷 256103-256103页
作者: Jun Chen Lizhi Ouyang Paul Rulis Anil Misra W. Y. Ching Department of Physics University of Missouri–Kansas City Kansas City Missouri 64110 USA Institute of Applied Physics and Computational Mathematics Beijing China 100088 Department of Civil and Mechanical Engineering School of Computing and Engineering University of Missouri–Kansas City Kansas City Missouri 64110 USA
The mechanical properties of a model of Y-doped intergranular glassy film in silicon nitride ceramics are studied by large-scale ab initio modeling. By linking directly to its electronic structure, it is shown that th... 详细信息
