Editor's note: This article has been updated to clarify that the new study in Physical Review Letters focuses on the detection of Unruh effect on a single accelerated particle, and to note that other ...
Matter is made of elementary particles, and the Standard Model of particle physics states that these particles occur in two families: leptons (such as electrons and neutrinos) and quarks (which make u...
In a step toward bridging the gap between fungal taxonomy and molecular ecology, scientists from several institutions including Los Alamos National Laboratory have characterized a sample of “mystery” ...
The sources of the high-energy cosmic neutrinos that are detected by the IceCube Neutrino Observatory buried in the Antarctic ice may be hidden from observations of high-energy gamma rays, new researc...
We establish weak and strong law of large numbers for a class of branching symmetric Hunt processes with the branching rate being a smooth measure with respect to the underlying Hunt process, and the ...
Bats use water ripples to hunt frogs(图)     Bats  frogs       2014/3/18
AUSTIN, Texas — As the male túngara frog serenades female frogs from a pond, he creates watery ripples that make him easier to target by rivals and predators such as bats, according to researchers fro...
A University of Queensland researcher has been awarded an $85,000 grant to identify the genes that underlie rare paediatric brain disorders.
Let $E$ be a locally compact separable metric space and $m$ be a positive Radon measure on it. Given a nonnegative function $k$ defined on $E\times E$ off the diagonal whose anti-symmetric part is ass...
In this paper we use the spine decomposition and martingale change of measure to establish a Kesten-Stigum Llog L theorem for branching Hunt processes. This result is a generalization of the results i...
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...
Until recently Cummingsella was only known by two rare and puzzling species, erected on very limited material. The genus was therefore considered as representing a very uncommon and puzzling form that...
UQ scientist Ian Mackay is always on the lookout for that lucky find – well, if you consider unknown strains of the common cold virus lucky. Dr Mackay's team has worked in this area for the past three...
本文首先讨论由正则半狄氏型所定义的一些概念与由相应Hunt过程所定义的一些概念之间的关系, 主要证明了例外集、${\cal E}$-例外集与半极集的等价性, q.e.精连续函数与${\cal E}$-拟连续函数的等价性. 接着讨论正则半狄氏型的部分, 证明了正则半狄氏型在一个开集上的部分仍是一个正则半狄氏型.
We review briefly the recent progress in the search for the quark-gluon plasma (QGP) at CERN SPS and BNL RHIC. Several model analyses and observables, such as hadronic thermal equilibrium, hydrodynami...
