A singular perturbation result for a class of periodic-parabolic BVPs

Open Mathematics
In this article, we obtain a very sharp version of some singular perturbation results going back to Dancer and Hess [Behaviour of a semilinear periodic-parabolic problem when a parameter is small, Lecture Notes in Mathematics, Vol. 1450, Springer-Verlag,

Positive solutions for the periodic-parabolic problem with large diffusion

Networks and Heterogeneous Media
In this paper, we study the positive solutions of the periodic-parabolic logistic equation with indefinite weight function and nonhomogeneous diffusion coefficient.

Recognising the Imminence of Suicide Risk—Reframing Positive Obligations Under the European Convention on Human Rights

The Howard Journal of Crime and Justice, EarlyView.
ABSTRACT This article reframes the concept of imminence of suicide risk of mentally ill offenders under Article 2 of the European Convention on Human Rights, which enshrines the right to life. The proposal is based on Article 2 domestic violence jurisprudence which has built its knowledge of lethal risk by reference to relevant expertise.

A priori bounds and existence of non-real eigenvalues of fourth-order boundary value problem with indefinite weight function

Electronic Journal of Differential Equations, 2016
In this article, we give a priori bounds on the possible non-real eigenvalue of regular fourth-order boundary value problem with indefinite weight function and obtain a sufficient conditions for such problem to admit non-real eigenvalue.

Reinforcement Learning in Modern Biostatistics: Constructing Optimal Adaptive Interventions

International Statistical Review, EarlyView.
Summary In recent years, reinforcement learning (RL) has acquired a prominent position in health‐related sequential decision‐making problems, gaining traction as a valuable tool for delivering adaptive interventions (AIs). However, in part due to a poor synergy between the methodological and the applied communities, its real‐life application is still ...

Medical Knowledge Integration Into Reinforcement Learning Algorithms for Dynamic Treatment Regimes

International Statistical Review, EarlyView.
Summary The goal of precision medicine is to provide individualised treatment at each stage of chronic diseases, a concept formalised by dynamic treatment regimes (DTR). These regimes adapt treatment strategies based on decision rules learned from clinical data to enhance therapeutic effectiveness.
