Maximum of Dyson Brownian motion and non-colliding systems with a boundary [PDF]

, 2009
We prove an equality-in-law relating the maximum of GUE Dyson's Brownian motion and the non-colliding systems with a wall. This generalizes the well known relation between the maximum of a Brownian motion and a reflected Brownian ...

Research on the Influence of Hydrofoil Propulsive Parameters on Propulsion Efficiency

Journal of Marine Science and Engineering
Oscillating hydrofoils can be used to simplify the study of the swinging caudal fin propulsive mode of fish, where the motion parameters have a direct impact on the hydrodynamic performance and propulsive efficiency. In this study, numerical calculations

Numerical simulation for peristalsis of Quemada fluid: A dynamic mesh approach

Journal of Advanced Research, 2023
Introduction: Flow dynamics due to the peristaltic pumping has been the topic of great interest for the researchers. But numerical and analytical analyses for the peristaltic motion are limited where flow domain is deformed real-time.

Unaffected perceptual thresholds for biological and non-biological form-from-motion perception in autism spectrum conditions [PDF]

, 2010
Background: Perception of biological motion is linked to the action perception system in the human brain, abnormalities within which have been suggested to underlie impairments in social domains observed in autism spectrum conditions (ASC).

Enhanced Power Extraction via Hybrid Pitching Motion in an Oscillating Wing Energy Harvester with Leading Flap

Energies
This study applied a hybrid pitching motion for an oscillating wing with a leading flap aimed at enhancing energy extraction efficiency. In the first half of the cycle, the hybrid pitching motion begins with a non-sinusoidal pitching motion for 0.0 ≤ t/T

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.

Enhancement Mechanism of Non-Sinusoidal Trajectory on Dual-Flapping-Wing Energy Harvesting Across Three Layouts

Aerospace
Flapping-wing energy harvesting is a promising technology for distributed wind energy utilization, yet the enhancement mechanism of non-sinusoidal motion trajectories across different dual-wing configurations remains insufficiently elucidated.

Temporal Interference Stimulation of Centromedian‐Parafascicular Complex in Disorders of Consciousness: A Pilot Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Treatment of disorders of consciousness (DoC) remains a major clinical challenge, and noninvasive, targeted modulation of deep brain structures has emerged as a promising therapeutic strategy. We aimed to evaluate the feasibility/safety and preliminary effects of thalamic temporal interference stimulation (TIS) targeting centromedian‐
