A chess-like board game developed by University of Michigan researchers helps small-scale Mexican coffee farmers better understand the complex interactions between the insects and fungi that live on t...
The National Science Board (NSB) announced today that Robert J. Birgeneau is the recipient of the 2016 Vannevar Bush Award. Birgeneau is chancellor emeritus at the University of California, Berkeley a...
发表在JGG2016年第一期上的两篇文章"Efficient targeted genome modification in maize using CRISPR/Cas9 system"(通讯作者:韩方普)和"Efficiency and inheritance of targeted mutagenesis in maize using CRISPR-Cas9"(通讯作者:赖锦盛)由 Maiz...
Vector measurements of the geomagnetic field have been made in the South Indian Ocean since 1988 when a Shipboard Three Component Magnetometer (STCM) was installed on board the icebreaker Shirase by t...
DIFFUSIVE MOTION AND RECURRENCE ON AN IDEALIZED GALTON BOARD     DIFFUSIVE MOTION  AN IDEALIZED GALTON BOAR       font style='font-size:12px;'> 2015/9/29
We study a mechanical model known as Galton board { a particle rolling on a tilted plane under gravitation and bouncing o a periodic array of rigid obstacles (pegs). This model is also identical to...
Galton Board: limit theorems and recurrence     limit theorems  recurrence       font style='font-size:12px;'> 2015/9/29
We study a particle moving in R 2 under a constant (external) force and bouncing o a periodic array of convex domains (scatterers); the latter must satisfy a standard ‘finite horizon’...
National Science Board to meet Nov. 19-20, 2014 in Arlington, Va.(图)     Arlington  Science       font style='font-size:12px;'> 2014/12/1
The National Science Board (NSB) will meet Nov. 19-20, 2014, to address science and engineering policy of interest to the National Science Foundation (NSF). Members of the media and the public are inv...
This site was created by the Water Science and Technology Board of the National Academies. Its purpose is to assist the work of water scientists, engineers, managers, policymakers, and students throug...
A special wire circuit with an appropriate layout was designed and formed on printed circuit board (PCB). After a current flowed through the wire circuit, the magnetic field was induced according to A...

Fast Timing Analysis of Cygnus X-1 using SPI on board INTEGRAL     Analysis  Cygnus  board INTEGRAL       font style='font-size:12px;'> 2011/9/29
For the very first time, we report the high frequency analysis of Cyg X-1 up to hard X-ray using SPI on-board INTEGRAL. After analyzing the possible contribution fromthe background, and using INTEGRAL...
The Swiss Board Directors Network in 2009     Boards of directors    Complex networks    Corporate governance       font style='font-size:12px;'> 2011/9/28
We study the networks formed by the directors of the most important Swiss boards and the boards themselves for the year 2009. The networks are obtained by projection from the original bipartite graph....
Predicting nonequilibrium fluctuations requires a knowledge of nonequilibrium distribution functions.Despite the distributions’ fractal character some theoretical results, “Fluctuation Theorems”,remin...
Using extensive Monte Carlo simulations we study numerically and analytically a photogalvanic effect, or ratchet, of directed electron transport induced by a microwave radiation on a semidisk Galton b...
Maker Can Construct a Sparse Graph on a Small Board     Sparse Graph  Small Board       font style='font-size:12px;'> 2010/11/15
We study Maker/Breaker games on the edges of sparse graphs. Maker and Breaker take turns in claiming previously unclaimed edges of a given graph H. Maker aims to occupy a given target graph G and Bre...
