Bifurcation Control of an Electrostatically-Actuated MEMS Actuator with Time-Delay Feedback
Micromachines, 2016 The parametric excitation system consisting of a flexible beam and shuttle mass widely exists in microelectromechanical systems (MEMS), which can exhibit rich nonlinear dynamic behaviors.

The Smart Detection of Ship Severe Roll Motions and Decision-Making for Evasive Actions
Journal of Marine Science and Engineering, 2020 This paper presents a numerical model for the smart detection of synchronous and parametric roll resonance of a ship. The model implements manoeuvring equations superimposed onto ship dynamics in waves.

Dynamics of Peccei-Quinn Breaking Field after Inflation and Axion Isocurvature Perturbations
, 2015 The Peccei-Quinn mechanism suffers from the problem of the isocurvature perturbations. The isocurvature perturbations are suppressed if the Peccei-Quinn breaking scale is large during inflation.

Statistics of resonance width shifts as a signature of eigenfunction non-orthogonality [PDF]
, 2012 We consider an open (scattering) quantum system under the action of a perturbation of its closed counterpart. It is demonstrated that the resulting shift of resonance widths is a sensitive indicator of the non-orthogonality of resonance wavefunctions ...

Parametric Resonance Climate Model
, 2023 Abstract The variations in the distribution of solar radiation due to the ∼105 years Milankovitch cycle alone cannot explain the sharp drop in temperature of approximately 10 K that marks the transition from the interglacial to the glacial age registered in the last ∼5.5 106 years temperature variation behavior.

Acoustic Measures Capture Speech Dysfunction in Spinocerebellar Ataxia
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Spinocerebellar ataxias (SCA) are hereditary cerebellar degenerative disorders with a common feature of dysarthria, involving impaired phonatory and articulatory control of speech, thereby affecting social communication. In this study, we investigated whether acoustic measures could objectively measure speech dysfunction and identify

Stochastic parametric resonance in shear flows [PDF]
Nonlinear Processes in Geophysics, 2005 Time-periodic shear flows can give rise to Parametric Instability (PI), as in the case of the Mathieu equation (Stoker, 1950; Nayfeh and Mook, 1995).

Are Kaluza-Klein modes enhanced by parametric resonance? [PDF]
, 2000 We study parametric amplification of Kaluza-Klein (KK) modes in a higher $D$-dimensional generalized Kaluza-Klein theory, which was originally considered by Mukohyama in the narrow resonance case.

Glymphatic Dysfunction Reflects Post‐Concussion Symptoms: Changes Within 1 Month and After 3 Months
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Mild traumatic brain injury (mTBI) may alter glymphatic function; however, its progression and variability remain obscure. This study examined glymphatic function following mTBI within 1 month and after 3 months post‐injury to determine whether variations in glymphatic function are associated with post‐traumatic symptom severity ...
