From searching for extraterrestrial life to tracking rainfall, non-experts are increasingly helping gather information to answer scientific questions. A hands-on, outdoor citizen science project, the ...
Hurricane forecasters will be ready for the upcoming peak of hurricane season, thanks to a partnership between the National Science Foundation (NSF) and the National Oceanic and Atmospheric Administra...
UC Berkeley astronomers will lead one of 16 new projects funded by NASA to coordinate different exoplanet searches to more efficiently find habitable planets around other stars, and perhaps extraterre...
Let $G$ be a connected graph. A vertex $w$ strongly resolves a pair $u$, $v$ of vertices of $G$ if there exists some shortest $u-w$ path containing $v$ or some shortest $v-w$ path containing $u$. A se...
In this short note we construct a simple cut-and-join operator representation for Kontsevich-Witten tau-function that is the partition function of the two-dimensional topological gravity. Our derivati...
Ever on the look-out for ultra-low radioactive materials to shield their sensitive experiments, nuclear physicists have struck gold with a consignment of lead that lay on the floor of the Mediterranea...
We determined the equation of state (EOS) of three silicate liquid compositions by shock compression of preheated samples up to 127 GPa. Diopside (Di; Ca2Mg2SiO6) at 1773 K, anorthite (An; CaAl2Si2O...
研究一类排队空间有限且服务台可修的非周期Fork-Join排队网络,给出求解稳态 概率的直接法和等效法,并计算一些排队指标和可修指标(如稳态队长、服务台的可用度和服 务台的失效概率),最后通过仿真验证其正确性.
14 April 2007,SAN FRANCISCO—Despite public perceptions that local school boards are battlegrounds over evolution and other science-related issues, board members in the Kansas City area are far more co...
January 17, 2007,The advent of 2007 brought some fresh faces to the Penn State Geography Department: Alex Klippel and Frank Hardisty. Alex joins the department as an Assistant Professor, specializing ...
02-Nov-2006,Five international organizations met in Paris on 20 October 2006 to advise the World Organization for Animal Health (OIE) on funding to help developing countries meet international standar...
Abstract: A series of hydrothermal experiments were performed to determine the phase relations on the beidellite-saponite pseudo-binary join. Quenched glasses with stoichiometric dehydrated compositio...
The phase relations at high pressure and high temperature for the FeTiO -MgTiO join were de-termined using several different experimental methods. Through a series of multi-anvil experiments,a phase ...
We report here an investigation of amphibole synthesis within the ternary system Ca Mg Si O (OH) - Mg Al Si O (OH) -Mg Si O (OH) (= TR-PG-MC) to define better the limits of solid solution for amphi...
