Symmetries make the world go round, but so do asymmetries. A case in point is an asymmetry known as charge–parity (CP) asymmetry, which is required to explain why matter vastly outnumbers antimatter i...

High-resolution marine magnetic surveys marine archaeological search ship-wreck amphorae
2015/9/8
Recently two marine magnetic surveys, combined with the use of a multi-beam sonar (Kongsberg Marittime EM
300 multibeam: 30 KHz frequency echosounder for hydrographic purposes; acoustic lobe composed...
Searching for the effects of the May-June 2012 Emilia seismic sequence (northern Italy):medium-depth deformation structures at the periphery of the epicentral area
Emilia 2012 earthquake Seismic effect Faulting Seismic reflection survey
2015/8/26
In 2012, a seismic sequence occurred in the lowlands of the Emilia-Romagna Region (northern Italy), between the borders of the Modena, Ferrara and Bologna Provinces. It consisted of seven mainshocks (...
Searching for a Trail of Evidence in a Maze
Detecting a chain of nodes in a network minimax detection Bayesian detection predictability profile of a stochastic process martingales exponential families of random variables
2015/6/17
Consider a graph with a set of vertices and oriented edges connecting pairs of vertices. Each vertex is associated with a random variable and these are assumed to be independent. In this setting, supp...
HST Pa Survey of the Galactic Center – Searching the missing young stellar populations within the Galactic Center
star formation process
2014/12/20
We present preliminary results of our \hst Pa$\alpha$ survey of the Galactic Center (\gc), which maps the central 0.65$\times$0.25 degrees around Sgr A*. This survey provides us with a more complete i...
Searching for seismo-ionospheric earthquakes precursors: Total Electron Content disturbances before 2005-2006 seismic events
seismo-ionoispheric earthquake precursors total electron content of ionosphere lithosphere-atmosphere-ionosphere coupling
2012/5/17
During earthquakes preparation periods significant disturbances in the ionospheric plasma density are often observed. These anomalies are caused by lithosphere-atmosphere-ionosphere interaction, parti...
Searching for initial mass function variations in resolved stellar populations
Searching function variations resolved stellar populations
2011/10/13
The initial mass function (IMF) succinctly characterizes a stellar population, provides a statistical measure of the end result of the star-formation process, and informs our under- standing of the st...
Searching for dark matter isocurvature initial conditions with N-body Simulations
Searching dark matter isocurvature initial conditions N-body Simulations
2011/10/12
Small fraction of isocurvature perturbations may exist and correlate with adiabatic perturbations in the primordial perturbations. Naively switching off isocurvature perturbations may lead to biased r...
Searching for Saturn's Dust Swarm: Limits on the size distribution of Irregular Satellites from km to micron sizes
Solar System: satellites
2011/10/8
We describe a search for dust created in collisions between the Saturnian irregular satellites using archival \emph{Spitzer} MIPS observations. Although we detected a degree scale Saturn-centric exces...
Searching for the QCD Critical Point Using Particle Ratio Fluctuations and Higher Moments of Multiplicity Distributions
QCD Particle Ratio Fluctuations Multiplicity Distributions
2011/7/20
Dynamical fluctuations in global conserved quantities such as baryon number, strangeness, or charge may be observed near a QCD critical point. Results from new measurements of dynamical $K/\pi$, $p/\p...
High Lundquist Number Resistive MHD Simulations of Magnetic Reconnection: Searching for Secondary Island Formation
Lundquist Number Resistive MHD Simulations Magnetic Reconnection
2011/9/9
Recently, secondary island formation due to the tearing instability of the Sweet-Parker current sheet was identified as a possible mechanism that can lead to fast reconnection (less sensitive dependen...
Searching for simplicity: Approaches to the analysis of neurons and behavior
the analysis neurons behavior
2011/1/5
What fascinates us about animal behavior is its richness and complexity, but understanding behavior and its neural basis requires a simpler description. Traditionally, simplification has been imposed ...
Searching for Young M Dwarfs with GALEX
Stars: activity chromospheres coronae late-type ages – Surveys
2010/11/15
The census of young moving groups in the solar neighborhood is significantly incomplete in the low-mass regime. We have developed a new selection process to find these missing members based on the GAL...
Searching for Needles in Haystacks - Using the Fermi/GBM to find GRB gamma-rays with the Fermi/LAT Detector
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/27
From the launch of the Fermi Gamma-ray Space Telescope to July 9, 2010, the Gamma-ray Burst Monitor (GBM) has detected 497 probable GRB events. Twenty-two of these satisfy the simultaneous requirement...
Searching for Needles in Haystacks - Looking for GRB gamma-rays with the Fermi/LAT Detector
