Detecting separate time scales in genetic expression data
Background Biological processes occur on a vast range of time scales, and many of them occur concurrently. As a result, system-wide measurements of gene expression have the potential to capture many of these processes simultaneously.

Adding a subjective dimension to an ICF-based disability measure for people with multiple sclerosis: development and use of a measure for perception of disabilities [PDF]
OBJECTIVE: The subjective dimension of disability, the perception of disability, is a dimension missing from the International Classification of Functioning, Disability and Health (ICF), and from health-related quality of life (HRQOL) instruments ...

Stability Analysis of a Damped Nonlinear Wave Equation [PDF]
The current manuscript is concerned with extracting an analytical approximate periodic solution of a damped cubic nonlinear Klein-Gordon equation. The Riemann-Liouville fractional calculus is utilized to obtain an analytic approximate solution.

On the multiple scales perturbation method for difference equations [PDF]
In the classical multiple scales perturbation method for ordinary difference equations (O Delta Es) as developed in 1977 by Hoppensteadt and Miranker, difference equations (describing the slow dynamics of the problem) are replaced at a certain moment in ...

Testing the method of multiple scales and the averaging principle for model parameter estimation of quasiperiodic two time-scale models [PDF]
summary:Some dynamical systems are characterized by more than one time-scale, e.g. two well separated time-scales are typical for quasiperiodic systems.

Multiple time scales of bank-full discharge in the Yellow River
Under the influence of climate changes,the hydrologic system has the characteristics of multiple time scales.The bank-full discharge,as a function of inflow conditions,also has the characteristics of multiple time scales.This phenomenon was studied based

Near scale-free dynamics in neural population activity of waking/sleeping rats revealed by multiscale analysis. [PDF]
A neuron embedded in an intact brain, unlike an isolated neuron, participates in network activity at various spatial resolutions. Such multiple scale spatial dynamics is potentially reflected in multiple time scales of temporal dynamics. We identify such
