Stability in quadratic variation, with applications
, 2020 We show that non continuous Dirichlet processes, defined as in \cite{NonCont} are closed under a wide family of locally Lipschitz continuous maps (similar to the time-homogeneous variants of the maps considered in \cite{Low}) thus extending Theorem 2.1. from that paper. We provide an Itô formula for these transforms and apply it to study of how $[f(X^n)

Second‐Harmonic Hyper‐Mie Optical Activity Enables Closed‐Loop Chiral Photochemistry
Advanced Materials, EarlyView.Nonlinear chiral photochemistry is demonstrated in CdTe/CdO nanohelices, where circularly polarized infrared light both drives and tracks photo‐oxidation via second‐harmonic scattering. This closed‐loop process reveals real‐time structural evolution, including shell fracturing and core exposure, accompanied by a transition from hyper‐Mie to hyper ...

On the quadratic variation process of a continuous Martingale
Illinois Journal of Mathematics, 1983 This article deals with the pathwise construction of the quadratic variation process \(\) associated to a continuous local martingale (M(t),\(t\geq 0)\). More precisely, for \(n\geq 1\) let the sequence \((T_ i^ n;i\geq 0)\) of stopping times \(T_ i^ n\) be defined by \(T_ 0^ n=0\), \(T^ n_{i+1}=\inf \{t\geq T_ i^ n:| M(t)-M(T_ i^ n)| \geq 2^{-n ...

A Survey of Interlayer Interaction Models for Graphene and Other 2D Materials
Advanced Materials Interfaces, EarlyView.Van der Waals interactions arising from electronic polarization at atomically close interfaces generate corrugated interlayer energy landscapes that govern normal and tangential tractions. This review presents an overview of quantum, atomistic, analytical, and continuum modeling approaches, highlighting their roles across length scales in capturing ...

On quadratic variations for the fractional-white wave equation
Theory of Probability and Mathematical Statistics, 2023 This paper studies the behaviour of quadratic variations of a stochastic wave equation driven by a noise that is white in space and fractional in time. Complementing the analysis of quadratic variations in the space component carried out in [Correlation structure, quadratic variations and parameter estimation for the solution to ...
