The Dynamics of Buoyant Microplastic in the Ocean Forced by Unsteady Insolation

Journal of Marine Science and Engineering, 2023
Building on the deterministic mathematical models of Kooi et al. (Environ. Sci. Technol. 51, 2017) and Kreczak et al. (Limnol. Oceanogr. 66, 2021), this study investigates the trajectories of biofouled microplastic particles forced by unsteady insolation.

Oscillators: Phenomenological mappings and analogies: First part: Mathematical analogy and chains [PDF]

Scientific Technical Review, 2015
New analytical and numerical results of dynamics for both linear and nonlinear system with two degrees of freedom are presented. For a mechanical chain system with two degrees of freedom, oscillations are investigated analytically and numerically with ...

Detection and Reconstruction of Bursting Oscillations in Complex Systems Using the HAVOK Analysis Framework

Algorithms
Multi-scale dynamical systems may exhibit bursting oscillations, which are typically identified by analyzing time series and phase portraits. However, in cases where bursting oscillations are not apparent, relying solely on these methods may have ...

Suppression of amplitude dependent closest tune approach and its behavior under forced oscillations

Physical Review Accelerators and Beams, 2019
An amplitude dependent closest tune approach (ADeCTA) was first observed in the LHC in 2012. This potentially harmful effect can be generated by linear coupling in conjunction with octupoles.

Personality Assessment, Forced-Choice. [PDF]

, 2015
Instead of responding to questionnaire items one at a time, respondents may be forced to make a choice between two or more items measuring the same or different traits. The forced-choice format eliminates uniform response biases, although the research on

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).

Chirped Bloch-harmonic oscillations in a parametrically forced optical lattice

Physical Review Research, 2023
The acceleration theorem for wave packet propagation in periodic potentials disentangles the k-space dynamics and real space dynamics. This is well known and understood for Bloch oscillations and super Bloch oscillations in the presence of position ...
