Ecohydrologists environmental damage from los fog observable outer space
2020/6/12
A new National Science Foundation-funded study led by ecohydrologists at Indiana University has shown for the first time that it's possible to use satellite data to measure the threat o...
Galaxies in a simulated Lambda CDM universe - II. Observable properties and constraints on feedback
feedback cluster
2014/12/23
We compare the properties of galaxies that form in a cosmological simulation without strong feedback to observations of the z= 0 galaxy population. We confirm previous findings that models without str...
On the Ratio of Circumference to Diameter for the Largest Observable Circles: An Empirical Approach
On the Ratio of Circumference Diameter the Largest Observable Circles Empirical Approach Instrumentation and Methods for Astrophysics
2012/4/19
I present here a measurement of pi as determined for the largest observable circles. Intriguingly, the value of 16/5 asserted by the House of Representatives of the State of Indiana in 1897 is still v...
Avoiding bias in reconstructing the largest observable scales from partial-sky data
Avoiding bias reconstructing largest observable partial-sky data
2011/10/18
Obscuration due to Galactic emission complicates the extraction of information from cosmological surveys, and requires some combination of the (typically imperfect) modeling and subtraction of foregro...
Dynamical Opacity-Sampling Models of Mira Variables. II: Time-Dependent Atmospheric Structure and Observable Properties of 4 M-Type Model Series
stars: AGB and post-AGB, stars: atmospheres, stars: variables: other, stars: mass loss
2011/10/11
We present 4 model series of the CODEX dynamical opacity-sampling models of Mira variables with solar abundances, designed to have parameters similar to $o$ Cet, R Leo and R Cas. We demonstrate that t...
Are gravitational waves from giant magnetar flares observable?
gravitational giant magnetar observable
2011/10/18
Are giant flares in magnetars viable sources of gravitational radiation? Few theoretical studies have been concerned with this problem, with the small number using either highly idealized models or as...
Joint Extremal Behavior of Hidden and Observable Time Series
tail chain time series joint extremal behavior ARCH
2011/8/24
Abstract: We analyze the joint extremal behavior of two real-valued processes (X_t) and (Y_t) which can be interpreted as an observable and an unobservable time series. Our analysis is motivated by th...
Flavor unification, dark matter, proton decay and other observable predictions with low-scale $S_4$ symmetry
Flavor symmetries Grand unification Proton decay Intermediate symmetry
2011/1/5
We show how gauge coupling unification is successfully implemented through non- supersym-metric GU ×Gf (GU = SU(5), SO(10); Gf = S4 , SO(3)f , SU(3)f ) at the grand unification scale MU > 1015 GeV usi...

Optimization of the transmission of observable expectation values and observable statistics in Continuous Variable Teleportation
transmission of observable expectation values observable statistics Continuous Variable Teleportation
2010/10/21
We analyze the statistics of observables in continuous variable (CV)quantum teleportation in the formalism of the characteristic function.We derive expressions for average values of output state obser...
Time as a Quantum Observable, Canonically Conjugated to Energy, and Foundations of Self-Consistent Time Analysis of Quantum Processes
Quantum Processes Canonically Conjugated Self-Consistent Time Analysis
2009/9/4
Recent developments are reviewed and some new results are presented in the study of time in quantum mechanics and quantum electrodynamics as an observable, canonically conjugate to energy. This paper ...
Trace initial interaction from final state observable in relativistic heavy ion collisions
angular-bin correlation patterns centrality in-plane out-of-plane
2009/8/13
In order to trace azimuthal angle dependence of the initial interaction in ultra-relativistic heavy ion collision, two azimuthal multiplicity-correlation patterns
— neighboring and fixed-to-arbitrary...
Predicting the future from observable sequences of events in astrophysics I. Maximum Likelihood Estimation for a fixed number of parameters
astrophysics Maximum Likelihood
2009/5/27
Using analytical and numerical methods, estimates are given of future predictions in astrophysics that can be gathered from a sequence of observed events, for example for γ-ray bursts. Some general pr...
