Arthritis Care &Research, EarlyView.Objective We assessed the effectiveness of PrismRA to improve clinical outcomes among patients with rheumatoid arthritis (RA) initiating treatment with a biologic or targeted synthetic disease‐modifying antirheumatic drug (b/tsDMARD). Methods PrismRA incorporated 19 gene expression features and four clinical features to assess a patient's likelihood of

Constrained controllability of nonlinear systems [PDF]
Proceedings of the 2003 American Control Conference, 2003., 1995 This paper contains constrained exact local controllability results for nonlinear abstract differential equations. A generalization of the open mapping theorem is used for the sufficient conditions to guarantee controllability. The values of controls are in a convex, closed cone with vertex at 0.

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems
International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

SUBOPTIMAL CONTROL OF NONLINEAR MULTI-AGENT SYSTEMS [PDF]
Научно-технический вестник информационных технологий, механики и оптики, 2013 The article deals with the issue of robust suboptimal control for multi-agent systems which model is represented by differential equations with Lipschitz nonlinearity. It is assumed that only scalar subsystem outputs are available to measurement.

Hysteresis Quantizer-Based Event-Triggered Control of Nonlinear Networked Control Systems
IEEE Access, 2019 In this paper, we present a novel event-triggered control mechanism for nonlinear systems with hysteresis quantization. To describe the tendency of the dynamic quantizer parameter, an auxiliary parameter is created and the relationship between the ...
