On Hardy-Hilbert-type inequalities with α-fractional derivatives
In the current manuscript, new alpha delta dynamic Hardy-Hilbert inequalities on time scales are discussed. These inequalities combine and expand a number of continuous inequalities and their corresponding discrete analogues in the literature.

Time scale bias in erosion rates of glaciated landscapes
Averaging time scale bias may produce an apparent acceleration of measured erosion rates in glaciated landscapes. Deciphering erosion rates over geologic time is fundamental for understanding the interplay between climate, tectonic, and erosional ...

Diversity of timescale promotes the maintenance of extortioners in a spatial prisoner’s dilemma game
Recently, a class of interesting strategies, named extortion strategies, has attracted considerable attention since such extortion strategies can dominate any opponent in a repeated prisoner's dilemma game.

The asymptotic properties of the dynamic equation with a delayed argument [PDF]
In this paper, we present some asymptotic results related to the scalar dynamic equation with a delayed argument. Using the time scale calculus we generalize some results known in the differential and difference case to the more general dynamic case.

Ancient mitochondrial DNA provides high-resolution time scale of the peopling of the Americas
Native American population history is reexamined using a large data set of pre-Columbian mitochondrial genomes. The exact timing, route, and process of the initial peopling of the Americas remains uncertain despite much research.

Increasing the Utilization of Transmission Lines Capacity by Quasi-Dynamic Thermal Ratings
The power grid is under pressure to maintain a reliable supply because of constrained budgets and environmental policies. In order to effectively make use of existing transmission lines, it is important to accurately evaluate the line capacity.
