Abstract: In this paper, we provide some results on the class of spatial autoregressive conditional heteroscedasticity (ARCH) models, which have been introduced in recent literature to model spatial conditional heteroscedasticity. That means that the variance in… read more here.

Abstract: Abstract The present work is concerned with assessing the vulnerability of seismically excited structures using non-deterministic analysis concepts, in order to take uncertainties into account. In this respect, uncertainties in both structural properties and earthquake… read more here.

DOI: 10.1088/1402-4896/abfd65
Abstract: This work approaches the Michaelis-Menten model for enzymatic reactions at a nanoscale, where we focus on the quasi-stationary state of the process. The entropy and the kinetics of the stochastic fluctuations are studied to obtain… read more here.
