Limit theorems for Markov-modulated and reflected diffusion processes [PDF]
, 2015 In this thesis, asymptotic properties of two variants of one-dimensional diffusion processes, which are Markov-modulated and reflected Ornstein-Uhlenbeck processes, are studied.

Confidence surfaces for the mean of locally stationary functional time series [PDF]
, 2021 The problem of constructing a simultaneous confidence band for the mean function of a locally stationary functional time series {Xi,n(t)}i=1,...n is challenging as these bands can not be built on classical limit theory.

Random central limit theorems for linear processes with weakly dependent innovations
, 2017 Random central limit theorems (CLTs) are established for a linear process driven by a strictly stationary ψ-weakly dependent process as well as for the ψ-weakly dependent process itself, whose dependence structure was introduced by Doukhan and Louhichi ...

New limit theorems for regular diffusion processes with finite speed measure [PDF]
, 2000 We derive limit theorems for diffusion processes that have a finite speed measure. First we prove a number of asymptotic properties of the density $rho_t = dmu_t /dmu$ of the empirical measure $mu_t$ with respect to the normalized speed measure $mu ...

Nonparametric Tests for Conditional Symmetry in Dynamic Models [PDF]
, 2007 This article proposes omnibus tests for conditional symmetry around a parametric function in a dynamic context. Conditional moments may not exist or may depend on the explanatory variables.

Advanced Functional Materials, EarlyView.Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,

Generalized spectral tests for the martingale difference hypothesis [PDF]
, 2006 This article proposes a test for the martingale difference hypothesis (MDH) using dependence measures related to the characteristic function. The MDH typically has been tested using the sample autocorrelations or in the spectral domain using the ...

Critical Coupling in Semi‐Trasparent Fano Resonators for Photothermal Converters
Advanced Functional Materials, EarlyView.An ultrathin metal–insulator multilayer architecture is engineered to exploit Fano‐resonant critical coupling, completely suppressing optical reflectance while achieving a balanced 50:50 trade‐off between absorbance and transmittance. Upon laser excitation at resonance, the metamaterial generates intense localized heat (ΔT≈550∘C$\Delta T {\approx }550^\

Advanced Materials, EarlyView.Uniform monolayer Cr2Ge2Te6 films are achieved on Si substrates by molecular beam epitaxy. Intrinsic ferromagnetism with perpendicular magnetic anisotropy is established in the films by anomalous Hall effect and superconducting quantum interference device measurements, albeit with strong magnetic fluctuations characteristic of its 2D nature.

Advanced Materials, EarlyView.Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...
