Radius Stabilization by Two-Loop Casimir Energy
, 2005 It is well known that the Casimir energy of bulk fields induces a non-trivial potential for the compactification radius of higher-dimensional field theories. On dimensional grounds, the 1-loop potential is ~ 1/R^4.

Weighted Nash Inequalities [PDF]
, 2010 Nash or Sobolev inequalities are known to be equivalent to ultracontractive properties of Markov semigroups, hence to uniform bounds on their kernel densities.

Minimum length effects in black hole physics
, 2014 We review the main consequences of the possible existence of a minimum measurable length, of the order of the Planck scale, on quantum effects occurring in black hole physics.

Entomologia Experimentalis et Applicata, Volume 173, Issue 12, Page 1278-1284, December 2025.Initial population size and resource availability are key factors regulating population dynamics, with growth rates typically declining as populations increase but rising with greater resources. In maize weevils, however, we found an unexpected negative effect of resource availability on intrinsic growth rates, contrary to conventional expectations. We

Decoupling Interday and Intraday Volatility Dynamics With Price Durations
Journal of Time Series Analysis, Volume 46, Issue 6, Page 1224-1250, November 2025.ABSTRACT This article introduces a novel framework for volatility estimation based on price durations with an adaptive price change threshold. This innovation allows us to disentangle daily and intraday volatility dynamics from price durations, which greatly simplifies the parametric modelling of price durations and hence leads to more accurate ...
