Dynamic Disturbance Minimization Control for Discrete Non-Linear Stochastic Systems

, 1993
A dynamic feedback control scheme is proposed to reduce the effect of process and measurement disturbances of known wave-form for a class of discrete non-linear stochastic systems.

Dynamical analysis of multi-nutrient and single microorganism chemostat model in a polluted environment

Advances in Difference Equations, 2018
In this paper, we propose a multi-nutrient and single microorganism chemostat model with stochastic effect and impulsive toxicant input. Firstly, for the system neglecting stochastic effect, we investigate the global dynamics including the existence and ...

Consensus Formation and Change are Enhanced by Neutrality

Advanced Science, EarlyView.
Neutral agents are shown to enhance both the formation and overturning of consensus in collective decision‐making. A general mathematical model and experiments with locusts and humans reveal that neutrality enables robust consensus via simple interactions and accelerates consensus change by reducing effective population size.

Stochastic Periodic Solution and Persistence of a Nonautonomous Impulsive System with Nonlinear Self-Interaction

Discrete Dynamics in Nature and Society, 2020
Considering periodic environmental changes and random disturbance, we explore the dynamical behaviors of a stochastic competitive system with impulsive and periodic parameters in this paper.

eQTL Meta‐Analysis Reveals Conserved and Population‐Specific Regulatory Variation Underlying Nutritional Trait Evolution and Domestication in Tomato

Advanced Science, EarlyView.
A comprehensive meta‐analysis of expression quantitative trait loci (eQTLs) across five diverse tomato populations reveals a high‐resolution atlas of transcriptional regulation and uncovers conserved and population‐specific regulatory architectures underlying fruit nutritional quality traits, including flavonoids, sugars, organic acids, carotenoids ...

Tumor‐Derived Alpha‐1 Antitrypsin Promotes Liver Metastasis of Colorectal Cancer Through the Neutrophil Extracellular Traps–CCDC25 Pathway

Advanced Science, EarlyView.
ABSTRACT Liver metastasis is a leading cause of mortality in colorectal cancer (CRC), where the inflammatory tumor microenvironment, specifically neutrophil infiltration, significantly promotes metastatic colonization. This study reveals a pro‐metastatic role for alpha‐1 antitrypsin (A1AT) in CRC liver metastasis via a dual mechanism involving ...

Gaussian Process and Disturbance Observer Based Control for Disturbance Rejection

, 2022
This paper proposes Gaussian process and disturbance observer-based (GP and DOB-based) control by stochastic learning of position-based disturbance, where patterned disturbance is effectively eliminated in positions such as the cogging force and ripple ...

Composite Robust $H_\infty$ Control for Uncertain Stochastic Nonlinear Systems With State Delay via a Disturbance Observer

IEEE Transactions on Automatic Control, 2018
In this note, the robust stochastic stabilization and robust $H_\infty$ control problems are investigated for uncertain stochastic time-delay systems with nonlinearity and multiple disturbances.

TSPYL5 Promotes Triple‐Negative Breast Cancer Metastasis by Antagonizing USP10‐Mediated PTEN Stabilization to Unleash a ZEB1‐Dependent EMT Program

Advanced Science, EarlyView.
The hyperactivation of PI3K/AKT signaling in PTEN wild‐type triple‐negative breast cancer represents a clinical paradox. We delineate a novel post‐translational regulatory axis wherein the oncogene TSPYL5 competitively antagonizes the deubiquitinase USP10.

Development of stochastic delay cost functions [PDF]

, 2020
When a disturbance cannot be absorbed by schedule buffer, the tactical schedule recovery process of an airline prioritises between flights. This considers the cost of delay and may result in a reallocation of scarce airport resources during turnaround ...
