Approximate analysis of search algorithms with “physical” methods
Statistical physics analysis of algorithms stochastic input the physical concept
2015/8/20
An overview of some methods of statistical physics applied to the analysis of algorithms for optimization problems (satisfiability of Boolean constraints, vertex cover of graphs, decoding, ...) with d...
Structural Analysis of Laplacian Spectral Properties with Application to Electric Transmission Networks
Laplacian Spectral Properties Electric Transmission Networks Optimization and Control
2011/8/18
Abstract: The spectrum of the Laplacian matrix of a network plays a key role in a wide range of dynamical problems associated with the network, from transient stability analysis of power networks to d...
Empirical analysis of collective human behavior for extraordinary events in blogosphere
Empirical analysis collective human behavior extraordinary events blogosphere
2011/8/11
Abstract: To explain collective human behavior in blogosphere, we survey more than 1.8 billion entries and observe statistical properties of word appearance. We first estimate the basic properties of ...
Arbitrary-order Hilbert spectral analysis for time series possessing scaling statistics: a comparison study with detrended fluctuation analysis and wavelet leaders
Arbitrary-order Hilbert spectral analysis time series wavelet leaders
2011/8/5
Abstract: In this paper we present an extended version of Hilbert-Huang transform, namely arbitrary-order Hilbert spectral analysis, to characterize the scale-invariant properties of a time series dir...
Probing Tissue Multifractality Using Wavelet based Multifractal Detrended Fluctuation Analysis: Applications in Precancer Detection
Fractal Multifractal detrended fluctuation analysis Phase contrast imaging Refractive index Cancer diagnosis
2011/8/4
Abstract: The refractive index fluctuations in the connective tissue layer (stroma) of human cervical tissues having different grades of precancers (dysplasia) was quantified using a wavelet-based mul...
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...
Non-commutative tomography: A tool for data analysis and signal processing
Non-commutative tomography data analysis signal processing
2011/8/2
Abstract: Tomograms, a generalization of the Radon transform to arbitrary pairs of non-commuting operators, are positive bilinear transforms with a rigorous probabilistic interpretation which provide ...
Diagrammatic Analysis of Charmless Three-Body B Decays
Diagrammatic Analysis Charmless Three-Body B Decays
2011/1/5
We express the amplitudes for charmless three-body B decays in terms of diagrams.As in two-body decays, we neglect annihilation-type contributions. When this is done, many of the exact, purely isospin...
Staggered chiral perturbation theory in the two-flavor case and SU(2) analysis of the MILC data
Staggered chiral perturbation theory two-flavor case SU(2) analysis of the MILC data
2011/1/13
In the light pseudoscalar sector, we study rooted staggered chiral perturbation theory in the
two-flavor case. The pion mass and decay constant are calculated through NLO for a partiallyquenched theo...
Statistical mechanical analysis of hierarchical random code ensemble in signal processing
Statistical mechanical analysis hierarchical random code ensemble signal processing
2010/11/23
We study a random code ensemble with a hierarchical structure, which is closely related to generalized random energy model with discrete energy values.Based on this correspondence, we analyze this ens...
We perform a Dalitz plot analysis of about 100, 000 D+ s decays to K+K−+ and measure the
complex amplitudes of the intermediate resonances which contribute to this decay mode.
A First Passage Time Analysis of Atomic-Resolution Simulations of the Ionic Transport in a Bacterial Porin
Atomic-Resolution Simulations Ionic Transport Bacterial Porin
2010/11/24
We have studied the dynamics of chloride and potassium ions in the interior of the OmpF porin
under the influence of an external electric field. From the results of extensive all-atom molecular dynam...
