Energy fluctuations, hydrodynamics and local correlations in harmonic systems with bulk noises
Energy fluctuations hydrodynamics local correlations harmonic systems Mathematical Physics
2012/6/12
In this note, I summarise and comment on joint work with C. Bernardin, V. Kannan and J. L. Lebowitz concerning two harmonic systems with bulk noises whose nonequilibrium steady states (NESS) are nearl...
Spatiotemporal correlations of handset-based service usages
Spatiotemporal correlations handset-based service usages Physics and Society
2012/4/20
We study spatiotemporal correlations and temporal inhomogeneities of handset-based service usages by analyzing a dataset collected from 124 users for over 16 months. The dataset consists of detailed i...
Capturing correlations in chaotic diffusion by approximation methods
Capturing correlations chaotic diffusion approximation methods
2011/9/21
Abstract: We investigate three different methods for systematically approximating the diffusion coefficient of a deterministic random walk on the line which contains dynamical correlations that change...

non-femtoscopic two-pion analytical models
2011/7/21
A simple model of non-femtoscopic particle correlations in proton-proton collisions is proposed.
Study of $ππ$ correlations at LHC and RHIC energies in $pp$ collisions within the quark-gluon string model
quark-gluon string model RHIC energies
2011/7/21
The Quark Gluon String Model (QGSM) reproduces well the global characteristics of the $pp$ collisions at RHIC and LHC, e.g., the pseudorapidity and transverse momenta distributions at different centra...
Initial fluctuation and dihadron and $γ$-hadron correlations in high-energy heavy ion collisions
Initial fluctuation dihadron $γ$-hadron
2011/7/21
Fluctuations in initial parton density give rise to fluctuating geometrical shapes and hot spots in high energy heavy ion collisions.
Three dimensional structure from intensity correlations
Three dimensional structure intensity correlations x-ray dilute ensembles
2011/8/5
Abstract: We develop the analysis of x-ray intensity correlations from dilute ensembles of identical particles in a number of ways. First, we show that the 3D particle structure can be determined if t...
Identity Method for Particle Number Fluctuations and Correlations
hadron chemical fluctuations incomplete particle identification identity method
2011/7/20
An incomplete particle identification distorts the observed event-by-event fluctuations of the hadron chemical composition in nucleus-nucleus collisions. A new experimental technique called the {\em i...
Analysis of cross-correlations in electroencephalogram signals as an approach to proactive diagnosis of schizophrenia
Flicker-noise spectroscopy Frequency-phase synchronization Cross-correlations Electroencephalogram signals
2011/8/3
Abstract: We apply flicker-noise spectroscopy (FNS), a time series analysis method operating on structure functions and power spectrum estimates, to study the clinical electroencephalogram (EEG) signa...
On the velocity distribution in homogeneous isotropic turbulence: correlations and deviations from Gaussianity
homogeneous isotropic turbulence deviations Gaussianity Fluid Dynamics
2011/8/1
Abstract: We investigate the single-point probability density function of the velocity in three-dimensional stationary and decaying homogeneous isotropic turbulence. To this end we apply the statistic...
We study the condensed fraction of a harmonically-trapped atomic Bose gas at the critical point predicted by mean-field (MF) theory. The non-zero condensed fraction f0 is induced by critical correlati...
Advancements in full jet reconstruction have made it possible to use jets as triggers in azimuthal angular correlations to study the modification of hard-scattered partons in the medium created in ult...
Initial fluctuation and dihadron and $γ$-hadron correlations in high-energy heavy ion collisions
Initial fluctuation dihadron high-energy heavy ion collisions
2011/7/22
Fluctuations in initial parton density give rise to fluctuating geometrical shapes and hot spots in high energy heavy ion collisions. Hydrodynamic evolution of these initial fluctuations lead to the f...
Untriggered di-hadron correlations in Pb-Pb collisions at $\sqrt{s_{NN}} =$ 2.76 TeV from ALICE
Pb-Pb collisions Untriggered di-hadron correlations ALICE
2011/7/20
We present measurements of untriggered di-hadron correlations as a function of centrality in Pb-Pb \sNN collisions, for charged hadrons with $p_{T} > 0.15$ GeV$/c$. These measurements provide a map of...
In recent years, the study of dihadron correlations has been one of the primary methods used to investigate the propagation and modification of hard-scattered partons through the QGP. Due to recent ad...
