Space‐Time Smoothness and Parsimony in Covariance Functions

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper challenges the trade off between computational efficiency and statistical accuracy within the framework of Gaussian space‐time processes. Under such a framework, the space‐time dependence is completely specified through the space‐time covariance function.

Attractors for an Energy‐Damped Viscoelastic Plate Equation

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a class of non‐autonomous beam/plate equations with an integro‐differential damping given by a possibly degenerate memory and an energy damping given by a nonlocal ε$$ \varepsilon $$‐perturbed coefficient. For each ε>0$$ \varepsilon >0 $$, we show that the dynamical system generated by the weak solutions of the ...

Structural complexity of hard substrates shapes shallow marine benthic communities

open access: yesOikos, EarlyView.
Structurally complex habitats offer niche diversity, with varying biotic and abiotic conditions, generally leading to higher biodiversity compared to simpler habitats. However, our understanding of the response of ecological communities to increased complexity and the underlying drivers remain ambiguous due to discrepancies in how complexity is ...
