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.

Spectral Density Function Analysis Reveals Coupled Relaxation and Resonance Modes in Fluorinated Elastomers: Comparison With Semicrystalline Poly(tetrafluoroethylene)

Magnetic Resonance in Chemistry, EarlyView.
We used static‐gradient 19F NMR imaging to compare molecular dynamics in semicrystalline polytetrafluoroethylene (PTFE) and amorphous fluorinated elastomer films. PTFE shows depth‐dependent motion, while the elastomer exhibits uniform dynamics with resonance‐like peaks in its spectral density, suggesting intrinsic vibrational modes.

Dynamic Behavior of a Two‐Degree‐of‐Freedom System With Electromagnetic Interaction via a Skew‐Symmetric Matrix

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.
