Anharmonic state counts and partition functions for molecules via classical phase space integrals in curvilinear coordinates

The Journal of Chemical Physics, 2013
An algorithm is presented for calculating fully anharmonic vibrational state counts, state densities, and partition functions for molecules using Monte Carlo integration of classical phase space. The algorithm includes numerical evaluations of the elements of the Jacobian and is general enough to allow for sampling in arbitrary curvilinear or ...

Multiple Wiener-itô integral expansions for level-crossing-count functionals

Probability Theory and Related Fields, 1991
This paper applies the stochastic calculus of multiple Wiener-Itô integral expansions to express the number of crossings of the mean level by a stationary (discrete- or continuous-time) Gaussian process within a fixed time interval [0,T]. The resulting expansions involve a class of hypergeometric functions, for which recursion and differential ...

Lower Bounds for the Counting Function of an Integral Operator

2012
The paper presents a lower bound for the number of eigenvalues of an integral operator k with continuous kernel\( \mathcal{K} \) lying in the interval \( (-\infty,t){\rm with} \; t\leq 0 \). The estimate is given in terms of some integrals of \( \mathcal{K} \)

STATISTICAL METHODS FOR SEQUENCING COUNT DATA AND INTEGRATIVE FUNCTIONAL GENOMICS

2019
One key aim in RNA-seq differential expression (DE) analysis is to detect genes with changes in expression level across conditions while controlling for biological and technical variation and biases that is present in the observations. One task is to accurately estimate the effect size, often in terms of a logarithmic fold change (LFC).
