On the Absolute Stability Problem for Nonlinear Feedback Systems [PDF]
, 1979 The paper considers the use of a pole/zero canonical form in the investigation of the absolute stability problem for nonlinear feedback systems. The canonical form is easily computed and has an interpretation in terms of a nested system feedback ...

A novel chaotic system with one absolute term: stability, ultimate boundedness, and image encryption
HeliyonThis paper proposes a system with an absolute term, exhibiting chaos. The system's dynamics are examined by computation of bifurcation and Lyapunov exponents. This system has a countable finite coexisting nested attractors.

Necessary and sufficient conditions for absolute stability: the case of second-order systems
, 1997 Absolute stability is perhaps the most well-known open problem in control theory as easily verifiable necessary and sufficient conditions for absolute stability have remained unattainable since the 1940's.

A Lyapunov-based perspective on absolute stability
at - AutomatisierungstechnikAbstract This article presents a unifying perspective on absolute stability concepts. In particular, it develops a Lyapunov-like explanatory framework for a nonscalar circle criterion with its small-gain and strict-passivity special cases.

Deep Learning Pose Estimation for Phenotyping of Co‐Occurring Hyperkinetic Movement Disorders
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To explore whether routine outpatient video combined with deep learning‐based pose estimation and clinically interpretable kinematic features can support multi‐label phenotyping of co‐occurring hyperkinetic movement disorders (HMDs).

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.

Global Rather Than Vertical‐Selective Saccadic Abnormalities in Progressive Supranuclear Palsy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective To test whether vertical saccades are preferentially affected in Progressive Supranuclear Palsy (PSP). Methods PSP patients (n = 24) were compared to age‐matched controls (n = 94) and two degenerative groups (Alzheimer's disease, n = 20; Lewy body disease, n = 50).
