The Maximum Principle for Optimal Control Problems with Time Delays

open access: yesSIAM Journal of Control and Optimization, 2017
: In this paper we present necessary conditions for optimal control problems with time delays. The dynamic constraint is formulated as a control delay differential equation, with time delays occuring in both state and control variables.

Precision‐Optimised Post‐Stroke Prognoses

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Current medicine cannot confidently predict who will recover from post‐stroke impairments. Researchers have sought to bridge this gap by treating the post‐stroke prognostic problem as a machine learning problem, reporting prediction error metrics across samples of patients whose outcomes are known.

Influence of Dystrophin Isoform Deficiency on Motor Development in Duchenne Muscular Dystrophy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective In Duchenne muscular dystrophy (DMD), lack of the shorter dystrophin isoforms Dp140 and Dp71 is associated with increased central nervous system (CNS) involvement. We aimed to investigate how CNS involvement affects motor development in young DMD boys.

Maximum principle and the fourth order boundary value problem

open access: yesMathematical Modelling and Analysis, 2011
This paper is devoted to the study the nonlinear boundary value problem . We state a maximum principle related with the operator  and apply it to prove the existence and approximation of solutions to the problem (i), (ii), in presence of properly ordered

The Diagnostic Value of Visual Evoked Potentials in Chronic Disorders of Consciousness

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective In chronic disorders of consciousness (DOCs), the distinction between vegetative state/unresponsive wakefulness syndrome (VS/UWS) and minimally conscious state (MCS) is as crucial as it is challenging. Evoked potentials (EPs) and event‐related potentials (ERPs) are helpful, but some limitations prevent their consistent use in the ...

Optimal Control of Polymer Flooding Based on Maximum Principle

open access: yesJournal of Applied Mathematics, 2012
Polymer flooding is one of the most important technologies for enhanced oil recovery (EOR). In this paper, an optimal control model of distributed parameter systems (DPSs) for polymer injection strategies is established, which involves the performance ...

Long‐Term Temporal Profile of Motor Recovery After Intracerebral Hemorrhage

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Limited data is available to describe the temporal profile of long‐term recovery over 1 year after the stroke in patients with spontaneous intracerebral hemorrhage (ICH). Methods A registered multicentral cohort was conducted to consecutively include non‐herniated supratentorial ICH patients from November 2013 to January 2023 ...

A strong maximum principle for the Paneitz operator and a non-local flow for the $Q$-curvature [PDF]

open access: yes, 2014
In this paper we consider Riemannian manifolds (M, g) of dimension n ≥ 5, with semi-positive Q-curvature and non-negative scalar curvature. Under these assumptions we prove (i) the Paneitz operator satisfies a strong maximum principle; (ii) the Paneitz ...

Lived and care experiences of chronic musculoskeletal shoulder pain in Australian adults: A qualitative study

open access: yesArthritis Care &Research, Accepted Article.
Objectives Australian evidence on lived and care experiences of chronic musculoskeletal shoulder pain (CMSP), irrespective of disorder classification or disease, is limited. However, such evidence is important for person‐centred care and informing local service pathways and care guidelines or standards.

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

open access: yesInternational Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.
