Maximum principle for near-optimality of stochastic delay control problem

open access: yesAdvances in Difference Equations, 2017
This paper is concerned with near-optimality for stochastic control problems of linear delay systems with convex control domain and controlled diffusion. Necessary and sufficient conditions for a control to be near-optimal are established by Pontryagin’s

Prevalence, determinants and outcomes of low disease activity and remission attainment in SLE patients with clinically active disease

open access: yesArthritis Care &Research, Accepted Article.
Objectives This study aimed to identify the frequency and determinants of Lupus Low Disease Activity State (LLDAS) and Definition of Remission in SLE (DORIS‐remission) attainment in systemic lupus erythematosus (SLE) patients with clinically active disease, and the frequency and determinants of flare and damage accrual after target attainment.

Quantum collapse rules from the maximum relative entropy principle

open access: yesNew Journal of Physics, 2016
We show that the von Neumann–Lüders collapse rules in quantum mechanics always select the unique state that maximises the quantum relative entropy with respect to the premeasurement state, subject to the constraint that the postmeasurement state has to ...

Effectiveness and safety of baricitinib for juvenile idiopathic arthritis associated uveitis or chronic anterior antinuclear antibody positive uveitis

open access: yesArthritis Care &Research, Accepted Article.
Objectives Evaluate the efficacy and safety of baricitinib in paediatric patients with active JIA‐U or chronic anterior ANA‐positive uveitis, who had an inadequate response to MTX or bDMARDs. Methods JUVE‐BRIGHT was an open‐label, active‐controlled, Phase‐3 multicentre trial which utilized a novel design, including 1:1 randomization to an active ...

Maximum principles for Laplacian and fractional Laplacian with critical integrability

open access: yes, 2019
In this paper, we study maximum principles for Laplacian and fractional Laplacian with critical integrability. We first consider $-\Delta u(x)+c(x)u(x)\geq 0$ in $B_1$ where $c(x)\in L^{p}(B_1)$, $B_1\subset \mathbf{R}^n$. As is known that $p=\frac{n}{2}$

Assessment of skin in patients with systemic sclerosis using high‐frequency ultrasound and shear wave elastography: A comparative study with histology, molecular and clinical parameters

open access: yesArthritis Care &Research, Accepted Article.
Objective Ultrasound (US) has been proposed as a potential tool for assessing skin fibrosis in systemic sclerosis (SSc). However, a large‐scale comparison of US‐based assessment with histological markers of skin fibrosis has not been reported. We evaluated the US‐based skin assessments for their face validity (differentiation between involved SSc and ...

Use of the Principles of Maximum Entropy and Maximum Relative Entropy for the Determination of Uncertain Parameter Distributions in Engineering Applications

open access: yesEntropy, 2017
The determination of the probability distribution function (PDF) of uncertain input and model parameters in engineering application codes is an issue of importance for uncertainty quantification methods. One of the approaches that can be used for the PDF
