Long-Time Data Storage: Relevant Time Scales
Challenges, 2011 Dynamic processes relevant for long-time storage of information about human kind are discussed, ranging from biological and geological processes to the lifecycle of stars and the expansion of the universe.

Discounting in Games across Time Scales [PDF]
Electronic Proceedings in Theoretical Computer Science, 2010 We introduce two-level discounted games played by two players on a perfect-information stochastic game graph. The upper level game is a discounted game and the lower level game is an undiscounted reachability game.

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 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.

A Hierarchy of Time-Scales and the Brain
PLoS Computational Biology, 2008 In this paper, we suggest that cortical anatomy recapitulates the temporal hierarchy that is inherent in the dynamics of environmental states. Many aspects of brain function can be understood in terms of a hierarchy of temporal scales at which representations of the environment evolve. The lowest level of this hierarchy corresponds to fast fluctuations

Time‐scale transformations of discrete time processes [PDF]
Journal of Time Series Analysis, 2003 Abstract. This paper investigates the effects of temporal aggregation when the aggregation frequency is variable and possibly stochastic. The results that we report include, as a particular case, the well‐known results on fixed‐interval aggregation, such as when monthly data are aggregated into quarters.

Journal of Mathematical Analysis and Applications, 2003 In this paper, the author defines the Riemann and Lebesgue integrals (more precisely, the Riemann and Lebesgue \(\Delta\)-integrals and \(\nabla\)-integrals) on time scales and studies their properties and relationship. In particular, the author presents results concerning the lower and upper Darboux sums, the Riemann sums, the Riemann and Lebesgue ...

Gronwall-OuIang-Type Integral Inequalities on Time Scales
Journal of Inequalities and Applications, 2010 We present several Gronwall-OuIang-type integral inequalities on time scales. Firstly, an OuIang inequality on time scales is discussed. Then we extend the Gronwall-type inequalities to multiple integrals.

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders
Population Ecology, EarlyView.We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...
