Positivity and nonexistence of solutions for quasilinear inequalities

open access: yesElectronic Journal of Differential Equations, 2016
We prove a positivity property and a nonexistence theorem for weak solutions of quasilinear differential equalities in R^N. To obtain our results, we use a comparison principle.

Comparison principle for unbounded viscosity solutions of degenerate elliptic PDEs with gradient superlinear terms [PDF]

open access: yesarXiv, 2010
We are concerned with fully nonlinear possibly degenerate elliptic partial differential equations (PDEs) with superlinear terms with respect to $Du$. We prove several comparison principles among viscosity solutions which may be unbounded under some polynomial-type growth conditions.

Epigenome‐wide association study, meta‐analysis, and multiscore profiling of whole blood in Parkinson's disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Objectives An increasing body of evidence indicates altered DNA methylation in Parkinson's disease, yet the reproducibility and utility of such methylation changes are largely unexplored. We aimed to further elucidate the role of dysregulated DNA methylation in Parkinson's disease and to evaluate the biomarker potential of methylation‐based ...

Generalized spreading speeds for lattice differential equations with time and space dependence

open access: yesElectronic Journal of Differential Equations, 2019
This article concerns the spatial spreading speeds for lattice differential equations with general time and space dependence. Firstly, we give the concept of spreading speed intervals.

Corrigendum for the comparison theorem in "A new definitions for a class of integro-differential equatons" [PDF]

open access: yesAnnales I.H.P. Analyse Nonlineaire, 24, 1, (2007), pp.167-169, 2010
By using the Jensen's maximum principle and the Alexandrov's theorem in the convex analysis, we present the nonlocal version of the Jensen-Ishii lemma, which leads to the precise argument for the comparison principle.

Handling rescue therapy in myasthenia gravis clinical trials: why it matters and why you should care

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
Abstract Myasthenia gravis (MG) clinical trials typically allow rescue therapy during follow‐up in the event of marked worsening of MG symptoms. Failure to appropriately address rescue therapy in defining treatment effects and planning statistical analyses may yield biased estimates, increase false positive rates, or decrease statistical power – all of
