On Some New Dynamic Inequalities Involving C-Monotonic Functions on Time Scales
In this paper, we establish some new dynamic inequalities involving C-monotonic functions with C≥1, on time scales. As a special case of our results when C=1, we obtain the inequalities involving increasing or decreasing functions (where for C=1, the 1 ...

Brief communication Decreasing fires in a Mediterranean region (1970–2010, NE Spain) [PDF]
We analyse the recent evolution of fires in Catalonia (north-eastern Iberian Peninsula), a typical Mediterranean region. We examine a homogeneous series of forest fires in the period 1970–2010.

The Friction Properties of Firebrat Scales
Friction is an important subject for sustainability due to problems that are associated with energy loss. In recent years, micro- and nanostructured surfaces have attracted much attention to reduce friction; however, suitable structures are still under ...

Liquidity management with decreasing returns to scale and secured credit line [PDF]
This paper examines the dividend and investment policies of a cash constrained firm that has access to costly external funding. We depart from the literature by allowing the firm to issue collateralized debt to increase its investment in productive assets resulting in a performance sensitive interest rate on debt.

In full transition: Key impacts of vanishing mountain ice on water-security at local to global scales [PDF]
Icy mountains with their surface ice in glaciers and subsurface ice in permafrost constitute important water towers relating to multiple human needs for water security.

Grazing-induced biodiversity loss impairs grassland ecosystem stability at multiple scales [PDF]
Livestock grazing is a major driver shaping grassland biodiversity, functioning and stability. Whether grazing impacts on grassland ecosystems are scale-dependent remains unclear.

A Robust Estimate of Continental‐Scale Terrestrial Carbon Sinks Using GOSAT XCO2 Retrievals
Satellite XCO2 retrievals could improve the estimates of surface carbon fluxes, but it remains unknown on what scales these estimates are robust. Here, we use the time‐dependent Bayesian synthesis top‐down method and prior net ecosystem exchanges (NEEs ...

Theory of rapid variation on time scales with applications to dynamic equations [PDF]
summary:In the first part of this paper we establish the theory of rapid variation on time scales, which corresponds to existing theory from continuous and discrete cases. We introduce two definitions of rapid variation on time scales.

Excitations Are Localized and Relaxation Is Hierarchical in Glass-Forming Liquids
For several atomistic models of glass formers, at conditions below their glassy-dynamics–onset temperatures, T_{o}, we use importance sampling of trajectory space to study the structure, statistics, and dynamics of excitations responsible for structural ...
