Multiple Lebesgue integration on time scales [PDF]
Advances in Difference Equations, 2006 We study the process of multiple Lebesgue integration on time scales. The relationship of the Riemann and the Lebesgue multiple integrals is investigated.

Valuation of Credit Derivatives with Multiple Time Scales in the Intensity Model
Journal of Applied Mathematics, 2014 We propose approximate solutions for pricing zero-coupon defaultable bonds, credit default swap rates, and bond options based on the averaging principle of stochastic differential equations.

Smooth Hazards With Multiple Time Scales. [PDF]
Stat MedABSTRACTHazard models are the most commonly used tool to analyze time‐to‐event data. If more than one time scale is relevant for the event under study, models are required that can incorporate the dependence of a hazard along two (or more) time scales.

Bayesian analysis of survival on multiple time scales
Statistics in Medicine, 1994 AbstractWe propose a Bayesian approach to the analysis of survival data on multiple time scales. Non‐parametric modelling of variation of rates with more than one time scale is achieved using priors which specifysmoothvariation. Computations are conveniently carried out using Gibbs sampling.

Metabolic imaging in multiple time scales. [PDF]
Methods, 2014 We report here a novel combination of time-resolved imaging methods for probing mitochondrial metabolism in multiple time scales at the level of single cells. By exploiting a mitochondrial membrane potential reporter fluorescence we demonstrate the single cell metabolic dynamics in time scales ranging from microseconds to seconds to minutes in response

Multiple time scales in modeling the incidence of infections acquired in intensive care units. [PDF]
BMC Med Res Methodol, 2016 Background When patients are admitted to an intensive care unit (ICU) their risk of getting an infection will be highly depend on the length of stay at-risk in the ICU.

On Multiple Convolutions and Time Scales [PDF]
Mathematical Problems in Engineering, 2013 The properties of the multiple Laplace transform and convolutions on a time scale are studied. Further, some related results are also obtained by utilizing the double Laplace transform. We also provide an example in order to illustrate the main result.

Divided and A-Divided Differences on Time Scales
, 2023 In this chapter, the divided differences and cr-divided differences on time scales are introduced. The Newton and cr-Newton interpolation polynomial are constructed. In addition, the Hermite interpolation polynomial on time scales is constructed by using

Multiple timing and spatial scaling for bifurcations
Nonlinear Dynamics, 2023 AbstractScaling time and spatial domains often seem natural in ODEs, but unfortunately, its useful explicit form does not always agree with intuition. After reviewing the well-known methods, multiple timing and averaging, we will show that algebraic timelike variables may play a part in bifurcations.

Mixed-Mode Oscillations with Multiple Time Scales [PDF]
SIAM Review, 2012 Mixed-mode oscillations (MMOs) are trajectories of a dynamical system in which there is an alternation between oscillations of distinct large and small amplitudes. MMOs have been observed and studied for over thirty years in chemical, physical, and biological systems.
