Nondegeneracy of the lump solution to the KP-I equation
, 2017 The KP-I equation \[ \partial_{x}\left( \partial_{t}u+\partial_{x}^{3}u+3\partial_{x}\left( u^{2}\right) \right) -\partial_{y}^{2}u=0 \] has a lump solution of the form $Q\left( x-t,y\right) ,$ where \[ Q\left( x,y\right) =Q\left( x,y\right) =4 ...

Stationary solutions for the Cahn-Hilliard equation [PDF]
, 1998 We study the Cahn-Hilliard equation in a bounded domain without any symmetry assumptions. We assume that the mean curvature of the boundary has a nongenerate critical point.

Arthritis Care &Research, EarlyView.Objective Although the definition of a gout flare is well established, the state of gout flare resolution has not yet been defined. This study aimed to explore patients’ experiences and perceptions of gout flare resolution. Methods Semistructured interviews were conducted with 24 people with gout, guided by open‐ended questions exploring their ...

Immunosuppressive Drug Use in Limited Systemic Sclerosis: An International Survey
Arthritis Care &Research, EarlyView.Objective Current guidelines recommend immunosuppressive treatment for diffuse cutaneous systemic sclerosis but are less clear on their use in limited cutaneous systemic sclerosis (lcSSc) in the absence of internal organ complications. We conducted an international survey to understand current immunosuppressive drug prescribing patterns in lcSSc ...

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.
