Trans-Planckian signals from the breaking of local Lorentz invariance

, 2007
This article examines how a breakdown of a locally Lorentz invariant, point-like description of nature at tiny space-time intervals would translate into a distinctive set of signals in the primordial power spectrum generated by inflation.

Generalized Second Law of Thermodynamics for FRW Cosmology with Power-Law Entropy Correction

, 2012
In this work, we have considered the power law correction of entropy on the horizon. If the flat FRW Universe is filled with the n components fluid with interactions, the GSL of thermodynamics for apparent and event horizons have been investigated for ...

Enhanced performance of substation dynamics during large induction motor starting using SVC

Alexandria Engineering Journal, 2018
Static Var Compensators (SVC) have been widely used to separately improve each of voltage variation performance and steady state power factor of industrial substations. However, these two functions are interdependent, power factor improvement tends to do

Effects of in-medium nucleon-nucleon cross section on collective flow and nuclear stopping in heavy-ion collisions in the Fermi-energy domain

, 2018
With the newly updated version of the ultrarelativistic quantum molecular dynamics (UrQMD) model, a systematic investigation of the effects of in-medium nucleon-nucleon ($NN$) elastic cross section on the collective flow and the stopping observables in $^

Bootstraping cointegration tests under structural co-breaks: a robust extended ECM test [PDF]

, 1998
The aim of the paper is the analysis of ECM bootstrap cointegration tests under structural breaks. Classical ECM tests depend on sorne nuisance parameters, which is an undesirable feature for empirical applications.
