Stochastic Approximation with Two Time Scales: The General Case [PDF]
Two time scale stochastic approximation is analyzed when the iterates on either or both time scales do not necessarily converge.

Conditional oscillation of half-linear Euler-type dynamic equations on time scales
We investigate second-order half-linear Euler-type dynamic equations on time scales with positive periodic coefficients. We show that these equations are conditionally oscillatory, i.e., there exists a sharp borderline (a constant given by the ...

Planck scale to Compton scale [PDF]
The Planck scale is considered to be a natural minimum scale, made up as it is solely of fundamental constants. However the Planck scale is well beyond the scales encountered in real life, these latter being at least of the order of the Compton scale. The Compton scale too is fundamental in the same sense -- it is made up of fundamental micro physical ...

New results for time reversed symplectic dynamic systems and quadratic functionals
In this paper, we examine time scale symplectic (or Hamiltonian) systems and the associated quadratic functionals which contain a forward shift in the time variable.

Qualitative aspects of Volterra integro-dynamic system on time scales
This paper deals with the resolvent, asymptotic stability and boundedness of the solution of time-varying Volterra integro-dynamic system on time scales in which the coefficient matrix is not necessarily stable.

A new geomagnetic polarity time scale for the Late Cretaceous and Cenozoic
We have constructed a magnetic polarity time scale for the Late Cretaceous and Cenozoic based on an analysis of marine magnetic profiles from the world's ocean basins. This is the first time, since Heirtzler et al. (1968) published their time scale, that

Estimates of some applicable inequalities on time scales [PDF]
The main objective of the paper is to establish explicit estimates on some applicable inequalities in two variables on time scales which can be used in the study of certain qualitative properties of dynamical equations on time scales.

Oscillation of second order neutral dynamic equations with distributed delay
In this paper, we establish new oscillation criteria for second order neutral dynamic equations with distributed delay by employing the generalized Riccati transformation.
