Quenched invariance principles for random walks and elliptic diffusions in random media with boundary [PDF]
, 2014 Via a Dirichlet form extension theorem and making full use of two-sided heat kernel estimates, we establish quenched invariance principles for random walks in random environments with a boundary.

Asymptotic properties of linear combinations of U-statistics with degenerate kernels [PDF]
, 2005 As an estimator of a real estimable parameter, we consider a linear combination of U-statistics which include V-statistic and limit of Bayes estimate (Toda and Yamato [9]).

External Bootstrap Tests for Parameter stability [PDF]
, 2002 This article considers tests for parameter stability over time in general econometric models, possibly nonlinear-in-variables. Existing test statistics are commonly not asymptotically pivotal under nonstandard conditions.

Estimation of the distribution of change-points with appliction to fMRI data [PDF]
, 2011 Change-point detection in sequences of functional data is examined where the functional observations are dependent and where the distributions of change- points from multiple subjects is required.

Joint Invariance Principles for Random Walks with Positively and Negatively Reinforced Steps [PDF]
, 2022 Given a random walk $$(S_n)$$ with typical step distributed according to some fixed law and a fixed parameter $$p \in (0,1)$$, the associated positively step-reinforced random walk is a discrete-time process which performs at each step, with probability $

A Perspective on Interactive Theorem Provers in Physics
Advanced Science, EarlyView.Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics

Advanced Science, EarlyView.This work provides a practical guide for neuroengineers to design advanced neural interfaces, embracing and tailoring the concept of functional disorder. By bridging 2D and 3D in vitro models, this work highlights how non‐periodic, spatially heterogeneous, multiscale nanotopography can enable more physiologically relevant platforms for studying neural ...

Detecting and estimating epidemic changes in dependent functional data [PDF]
, 2011 Change point detection in sequences of functional data is examined where the functional observations are dependent. Of particular interest is the case where the change point is an epidemic change (a change occurs and then the observations return to ...

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws
Advanced Intelligent Discovery, EarlyView.The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...
