Level Crossing Analysis of Cosmic Microwave Background Radiation: A method for detecting cosmic strings
Cosmic Microwave Background Radiation detecting cosmic strings
2010/12/27
In this paper we study the footprint of cosmic string as the topological defects in the very early universe on the cosmic microwave background radiation. We develop the method of level crossing analy...
The level crossing analysis of German stock market index (DAX) and daily oil price time series
German stock market index daily oil price time series
2010/4/27
The level crossing analysis of DAX and oil price time series are given. We determine the average frequency of positive-slope crossings, $\nu_{\alpha}^+$, where $T_{\alpha} =1/\nu_{\alpha}^+ $ is the a...

Level Crossing of N*(1535)hole and η Modes and Partial Restoration of Chiral Symmetry in ηmesic Nuclei
A etamesic nuclei N*(1535) in medium partial restoration of chiral symmetry
2009/10/29
We investigate the properties of the ηnucleus interaction by postulating the N*(1535) dominance for ηN system. Since the mass gap of N* and N is very close to the η meson mass, there is the possi...
Level crossing and local time for regularized Gaussian processes
Level crossing local time regularized Gaussian processes

Let (X,,t~ [0, 11) be a oentred stationary Gaussian
process defined on (D,A , P) with covariance function satisfying
Define the regularized process
X' = cp, * X and YE = Xc/oe, where CT~ = var Xf ,...
