Development of a Disease Activity Index for the Assessment of VEXAS Syndrome (VEXAS‐DAI)
Arthritis Care &Research, EarlyView.Objective Vacuoles, E1 enzyme, X‐linked, autoinflammatory, somatic syndrome (VEXAS) syndrome is characterized by a complex spectrum of inflammatory and hematologic manifestations. Clinical research to identify effective therapies is urgently needed but is hindered by the lack of validated outcome measures.

Arthritis Care &Research, EarlyView.Objective Youth who experience a sport‐related knee injury have elevated odds of becoming overweight or developing obesity in 3 to 10 years, compounding their risk for posttraumatic osteoarthritis (PTOA). To inform prevention strategies, this study compared patterns of adiposity change between youth with a sport‐related knee injury and uninjured youth ...

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.

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.

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 ...
