Noether's theorem on time scales [PDF]
Journal of Mathematical Analysis and Applications, 2008 We show that for any variational symmetry of the problem of the calculus of variations on time scales there exists a conserved quantity along the respective Euler-Lagrange extremals.

The Convolution on Time Scales [PDF]
Abstract and Applied Analysis, 2007 The main theme in this paper is an initial value problem containing a dynamic version of the transport equation. Via this problem, the delay (or shift) of a function defined on a time scale is introduced, and the delay in turn is used to introduce the convolution of two functions defined on the time scale.

Irreversibility time scale [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2006 Entropy creation rate is introduced for a system interacting with thermostats (i.e., for a system subject to internal conservative forces interacting with “external” thermostats via conservative forces) and a fluctuation theorem for it is proved. As an application, a time scale is introduced, to be interpreted as the time over which irreversibility ...

Time scale evolution of avipoxviruses [PDF]
Infection, Genetics and Evolution, 2015 Avipoxviruses are divided into three clades: canarypox-like viruses, fowlpox-like viruses, and psittacinepox-like viruses. Several molecular clock and demographic models available in the BEAST package were compared on three avipoxvirus genes (P4b, cnpv186 and DNA polymerase genes), which enabled to determine that avipoxviruses evolved at a rate of 2-8 ...

Integrable equations on time scales [PDF]
Journal of Mathematical Physics, 2005 Integrable systems are usually given in terms of functions of continuous variables (on R), in terms of functions of discrete variables (on Z), and recently in terms of functions of q-variables (on Kq). We formulate the Gel’fand-Dikii (GD) formalism on time scales by using the delta differentiation operator and find more general integrable nonlinear ...

An Equivalence Scale for Time [PDF]
Social Indicators Research, 1998 This article proposes an ‘equivalence scale for time’ by which information on total working time in both paid and unpaid labour can be derived from information about paid working time and household structure. Different scales are offered for males and females, and an adjustment according to year is also provided.

The Time Scale of Evolution [PDF]
, 2018 AbstractFitness is a measure of how quickly alleles change in frequency under natural selection. Time is always implicit in evolutionary models but its units are rarely made explicit. When measuring phenotypes such as absolute growth rate, the units of measurement need to be made explicit.
