Nonparametric Survival Estimation With Contaminated and Adjudicated Events
Scandinavian Journal of Statistics, EarlyView.ABSTRACT We study the conditional expert Kaplan–Meier estimator, an extension of the classical Kaplan–Meier estimator designed for time‐to‐event data subject to both right‐censoring and contamination. Such contamination, where observed events may not reflect true outcomes, is common in applied settings, including insurance and credit risk, where expert

Vector: The Journal of Engineering, Volume 2027, Issue 1, January/December 2027.This study is concerned with the application of consensus control to a class of discrete‐time nonlinear multi‐agent systems with unknown inputs and additive noise. The aim is to design an extended Kalman unknown input observer (EKUIO) such that the state vector of a discrete‐time nonlinear system can be estimated, additive noise can be mitigated, and ...

Design Principles for Light‐Scattering Reservoir Computing at the Edge of Chaos
Advanced Computing, Volume 1, Issue 1, December 2026.Here we realize a light‐scattering reservoir computer operating with measurement‐modulation feedback, physically tunable in three axes—reservoir dynamics, input‐reservoir coupling, and reservoir interconnectivity. Sweeping each axis, we locate the axis‐specific optimum of memory capacity; the dynamic axis displays the sharpest optimum.

Surrogate‐Assisted Nonlinear Model Predictive Control for a Lambda Robot
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT This work presents a nonlinear model predictive control (NMPC) framework for a lambda‐shaped parallel robot that incorporates data‐driven surrogates to facilitate control design. An inverse surrogate model is used to provide an efficient initialization of the control inputs for NMPC.
