Phenotypical Differentiation of Tremor Using Time Series Feature Extraction and Machine Learning
Movement Disorders, EarlyView.Abstract Background The clinical diagnosis of tremor disorders depends on the interpretation of subtle movement characteristics, signs, and symptoms. Given the absence of a universally accepted biomarker, differentiation between essential tremor (ET) and tremor‐dominant Parkinson's disease (PD) frequently proves to be non‐trivial. Objective To identify

Defining the Rhythm: Developing a New Method to Describe Tremor and Myoclonus
Movement Disorders, EarlyView.Abstract Background The hallmark feature of tremor is rhythmicity, which can be quantified using power spectral density (PSD) analysis. However, tremor exhibits considerable variability, ranging from highly regular to more irregular patterns. Similarly, rhythmicity in myoclonus varies, but it typically manifests as arrhythmic jerks.

Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT The existence of one or two strictly positive solutions of Neumann boundary value problems is studied in this paper where the nonlinearities are L1$$ {L}^1 $$‐Carathéodory functions, so they are not necessarily continuous. Additional weaker and better conditions than those used in previous results are posted on the nonlinearities to obtain ...

International Journal of Mechanical System Dynamics, EarlyView.ABSTRACT This paper analyzes the dynamic behavior of a two‐degree‐of‐freedom system subjected to electromagnetic interaction modelled through a skew‐symmetric coupling matrix. The system comprises two mechanically independent oscillators coupled by velocity‐dependent electromagnetic forces.
