Goursat problem for the Yang-Mills-Vlasov system in temporal gauge

Electronic Journal of Differential Equations, 2011
This article studies the characteristic Cauchy problem for the Yang-Mills-Vlasov (YMV) system in temporal gauge, where the initial data are specified on two intersecting smooth characteristic hypersurfaces of Minkowski spacetime $(mathbb{R}^{4},eta )$

Real‐world Longitudinal Data on the Impact of Hydroxychloroquine Blood Level Monitoring on Lupus Outcomes: Results of a Prospective Longitudinal Cohort Study

Arthritis Care &Research, Accepted Article.
Objectives Hydroxychloroquine (HCQ) is a cornerstone therapy in systemic lupus erythematosus (SLE), yet the weight‐based dosing does not account for clinical factors that can introduce individual variability in drug metabolism and clearance. We leveraged longitudinal data from a prospective SLE cohort to: 1) identify clinical factors that predict ...

Riemann problem for a two-dimensional quasilinear hyperbolic system

Electronic Journal of Differential Equations, 2015
This article concerns the study of the Riemann problem for a two-dimensional non-strictly hyperbolic system of conservation laws. The initial data are three constant states separated by three lines and are chosen so that one of the three interfaces ...

Safety of Prescription Nonsteroidal Anti‐inflammatory Drugs in Adults with Inflammatory Bowel Disease: Data from a Large Administrative Claims Cohort

Arthritis Care &Research, Accepted Article.
Objectives The concern that nonsteroidal anti‐inflammatory drugs (NSAIDs) may precipitate flares of inflammatory bowel disease (IBD) has limited their use in managing musculoskeletal symptoms in this population, but safety data are mixed. Methods This retrospective cohort study included patients with IBD ≥ 18 years of age from Optum's de‐identified ...

Discordance between patient and physician global assessments in early systemic sclerosis

Arthritis Care &Research, Accepted Article.
Objective This study aims to identify factors associated with patient and physician global assessments and discordance between them in systemic sclerosis (SSc). Methods Data from adults with early SSc (< 5 years) from the CONQUER registry were included.

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.

An Adaptive Human Pilot Model With Reaction Time Delay for Enhanced Adaptive Control in Piloted Systems

International Journal of Adaptive Control and Signal Processing, EarlyView.
This work introduces an adaptive human pilot model that captures pilot time‐delay effects in adaptive control systems. The model enables the prediction of pilot–controller interactions, facilitating safer integration and improved design of adaptive controllers for piloted applications.
