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.

Divergence or convergence? Health inequalities and policy in a devolved Britain [PDF]

, 2009
Since the advent of political devolution in the UK, it has been widely reported that markedly different health policies have emerged. However, most of these analyses are based on a comparison of health care policies and, as such, only tell part of a ...

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller

International Journal of Adaptive Control and Signal Processing, EarlyView.
Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...

Representing Neighborhood Health: Exploring Citizen Science as a Democratic Force

Citizen Science: Theory and Practice
In discussions about citizen science (CS), scholars have considered CS as not only a tool to produce better science, but also a democratizing practice allowing for new definitions of public problems. Inspired by science and technology studies, we present

Gender variations in the relationship between social capital and mental health outcomes among the Indigenous populations of Canada

International Journal for Equity in Health, 2019
Background In this paper we examine the relationship between social capital and two mental health outcomes—self-rated mental health (SRMH) and heavy episodic drinking (HED)—among the Indigenous populations of Canada. We operationalize a unique definition

Inequalities in health [PDF]

Injury Prevention, 1999
In July 1997, shortly after the election of the new Labour government in the UK, the Secretary of State for Health asked Sir Donald Acheson, the recently retired Chief Medical Officer, to head an inquiry into inequalities in health in England and identify priority areas for policies to reduce inequalities.

Imaging of Biphoton States: Fundamentals and Applications

Advanced Functional Materials, EarlyView.
Quantum states of two photons exhibit a rich polarization and spatial structure, which provides a fundamental resource of strongly correlated and entangled states. This review analyzes the physics of these intriguing properties and explores the various techniques and technologies available to measure them, including the state of the art of their ...

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

Advanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.
