On Delay-independent Stability of a class of Nonlinear Positive Time-delay Systems
, 2013 We present a condition for delay-independent stability of a class of nonlinear positive systems. This result applies to systems that are not necessarily monotone and extends recent work on cooperative nonlinear systems.Comment: 9 ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Glioma recurrence severely impacts patient prognosis, with current treatments showing limited efficacy. Traditional methods struggle to analyze recurrence mechanisms due to challenges in assessing tumor heterogeneity, spatial dynamics, and gene networks.

Stability of pole solutions for planar propagating flames: II. Properties of eigenvalues/eigenfunctions and implications to stability [PDF]
, 2000 In a previous paper (Part I) we focused our attention on pole solutions that arise in the context of flame propagation. The nonlinear development that follows after a planar flame front becomes unstable is described by a single nonlinear PDE which admits

Nonlinear stability of vortex patches [PDF]
Transactions of the American Mathematical Society, 1987 To establish the nonlinear (Liapunov) stability of both circular and elliptical vortex patches in the plane for the nonlinear dynamical system generated by the two-dimensional Euler equations of incompressible, inviscid hydrodynamics. This is accomplished by using a relative variational principle in terms of energy function. A counterexample shows that

Fluid Biomarkers of Disease Burden and Cognitive Dysfunction in Progressive Supranuclear Palsy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Identifying objective biomarkers for progressive supranuclear palsy (PSP) is crucial to improving diagnosis and establishing clinical trial and treatment endpoints. This study evaluated fluid biomarkers in PSP versus controls and their associations with regional 18F‐PI‐2620 tau‐PET, clinical, and cognitive outcomes.

Nonlinear stability for 2 dimensional plane Couette flow
Revista Integración, 2004 In this expository article, we discuss the application of the resolvent technique to prove nonlinear stability of 2 dimensional plane Couette flow. Using this technique, we show how one can derive a threshold amplitude for perturbations that can lead to ...
