Antarctic detector offers first look at how Earth stops high-energy neutrinos in their tracks
Antarctic detector Earth stops high-energy neutrinos their tracks
2017/11/24
An interdisciplinary team of researchers using the IceCube Neutrino Observatory in Antarctica has measured how certain high-energy neutrinos are absorbed by the Earth, as opposed to passing through ma...
Inverted,but not perfectly:First trace of differences between matter and “ordinary” antimatter
Inverted but not perfectly First trace differences between matter ordinary antimatter
2017/3/14
In data collected during the first phase of operation of the Large Hadron Collider the LHCb collaboration team has discovered an interesting asymmetry. The most recent analysis of decays of the beauty...
The National Science Foundation (NSF) has issued its first-ever awards for the NSF INCLUDES program, a comprehensive initiative to enhance U.S. leadership in science and engineering by broadening part...
Iowa State physicist analyzes first electron neutrino data from NOvA Experiment
Iowa State physicist first electron neutrino data NOvA Experiment
2016/4/25
Mayly Sanchez clicked to a presentation slide showing the telltale track of an electron neutrino racing through the 14,000-ton Far Detector of the NOvA Neutrino Experiment.Since that detector sta...
Percolation in Interdependent and Interconnected Networks: Abrupt Change from Second to First Order Transition
Cascading failures, Percolation, Coupled networks, Phase transition
2011/9/5
Robustness of two coupled networks system has been studied only for dependency coupling (S. Buldyrev et. al., Nature, 2010) and only for connectivity coupling (E. A. Leicht and R. M. D’Souza, arxiv:09...
CoRoT\,102699796, the first metal-poor Herbig Ae pulsator: a hybrid $δ$ Sct-$γ$ Dor variable?
stars: pre-main-sequence – stars: variables: T Tauri, Herbig Ae/Be variables: Scuti stars: fundamental parameters stars: abundances infrared:stars.
2011/9/9
We present the analysis of the time series observations of CoRoT102699796 obtained by the CoRoT satellite that show the presence of five independent oscilla-
tion frequencies in the range 3.6-5 c/d. ...
First experience in operating the population of the condition databases for the CMS experiment
CMS experiment condition data
2010/3/15
Reliable population of the condition databases is critical for the correct operation of the online selection as well as of the offline reconstruction and analysis of data. We will describe here the sy...
Small Scale Magnetic Field Evolution In The First Objects Formed In The Universe
Small Scale Magnetic Field Evolution The First Objects In The Universe
2010/10/27
Large scale magnetic fields in galaxies are thought to be generated, by a mean field dynamo. In order to have generated the fields observed, the dynamo would have had to have operated for a sufficient...
Revisiting the First-Principles Approach to the Granular Gas Steady State
the First-Principles Approach the Granular Gas Steady State
2010/10/26
We extend a Fokker-Planck formalism, previously used to describe the behavior of a cooling granular gas, with a Hertzian contact potential and viscoelastic radial friction, giving a velocity dependent...
A First Principles Investigation of Mercuric Iodide: Bulk Properties and Intrinsic Defects
Mercuric Iodide Bulk Properties Intrinsic Defects
2010/10/22
We carried a theoretical investigation on the properties of mercuric iodide in the red tetragonal crystalline phase, and its respective intrinsic defects. Our calculations were performed using the ab ...
Diluted Magnetic Ga1 - xMnxN Alloys: a First-Principles Study
Diluted Magnetic Ga1 - xMnxN Alloys a First-Principles Study
2010/10/22
The utilization of the quantum properties of the electron spin wave function will allow the development of a new class of devices. The problem is still controversial and unsettled, even qualitatively,...
