A smoothing algorithm for systems with multiplicative noise [PDF]
IEEE Transactions on Automatic Control, 1988 A fixed-point smoothing algorithm is derived for systems with multiplicative noise in the state channels of the plant and the measurements as well as additive noise. As in systems without multiplicative noise the smoothed estimates depend on the filtered estimates. The steady-state behavior of the algorithm is examined.

Transient behavior of a population dynamical model [PDF]
, 2004 The transient behavior of an ecosystem with N random interacting species in the presence of a multiplicative noise is analyzed. The multiplicative noise mimics the interaction with the environment.

Homogenization for deterministic maps and multiplicative noise [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2013 A recent paper of Melbourne & Stuart (2011 A note on diffusion limits of chaotic skew product flows. Nonlinearity 24 , 1361–1367 (doi:10.1088/0951-7715/24/4/018)) gives a rigorous proof of convergence of a fast–slow deterministic system to a stochastic differential equation with additive noise.

Data‐Driven Distributed Safe Control Design for Multi‐Agent Systems
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents a data‐driven control barrier function (CBF) technique for ensuring safe control of multi‐agent systems (MASs) with uncertain linear dynamics. A data‐driven quadratic programming (QP) optimization is first developed for CBF‐based safe control of single‐agent systems using a nonlinear controller. This approach is then extended to the

The Analytical Solutions of the Stochastic mKdV Equation via the Mapping Method
Mathematics, 2022 Here, we analyze the (2+1)-dimensional stochastic modified Kordeweg–de Vries (SmKdV) equation perturbed by multiplicative white noise in the Stratonovich sense.

Bistable stochastic processes in the q-exponential family
, 2010 Stochastic bistable systems whose stationary distributions belong to the q-exponential family are investigated using two approaches: (i) the Langevin model subjected to additive and quadratic multiplicative noise, and (ii) the superstatistical model ...

When multiplicative noise stymies control [PDF]
The Annals of Applied Probability, 2019 We consider the stabilization of an unstable discrete-time linear system that is observed over a channel corrupted by continuous multiplicative noise. Our main result shows that if the system growth is large enough, then the system cannot be stabilized in a second-moment sense.

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.By fabricating and covalently assembling gelatin methacryloyl (GelMA) porous microgels, a new class of granular hydrogel scaffolds with hierarchical porosity is developed. These scaffolds have a significantly higher void fraction than their counterparts made up of nonporous microgels, enhancing cell recruitment and tissue integration. This research may

Advanced Functional Materials, EarlyView.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...
