Dynamics of a state-dependent delay-differential equation
Electronic Journal of Qualitative Theory of Differential EquationsWe present a detailed study of a scalar differential equation with threshold state-dependent delayed feedback. This equation arises as a simplification of a gene regulatory model.

Stabilizability and stability robustness of state derivative feedback controllers
, 2008 We study the stabilizability of a linear controllable system using state derivative feedback control. As a special feature the stabilized system may be fragile, in the sense that arbitrarily small modelling and implementation errors may destroy the asymptotic stability.

Derivative and proportional state feedback for linear descriptor systems with variable coefficients
Linear Algebra and its Applications, 1997 This paper considers linear time-varying descriptor control systems in the form \(Ex'- Ax- Bu= 0\), \(y= Cx\). Thus \(E\), \(A\), \(B\), \(y\) all vary with time. Results are given which characterize when linear time-varying proportional and derivative output feedback controls, \(u= Fy+ Gy'+ v\), with \(G\), \(F\) time-varying, regularize the original ...

Arthritis Care &Research, EarlyView.Objective We aimed to test the efficacy of personalized treatment of older veterans with chronic low back pain (CLBP) delivered by Aging Back Clinics (ABCs) as compared with usual care (UC). Methods Two hundred ninety‐nine veterans aged 65 to 89 with CLBP from three Veterans Affairs (VA) medical centers underwent baseline testing, randomization to ABC ...
