A discontinuously coupled network of phase oscillators replicate actomyosin cooperation

B. Warmington, J. Rossiter, H. Gadelha

This paper introduces a phase oscillator model to explain actomyosin oscillations, showing that cooperative behavior arises from mechanical coupling rather than molecular kinetics.

Direct Measurement of Unsteady Microscale Stokes Flow Using Optically Driven Microspheres

N. Bruot, P. Cicuta, H. Gadelha, R. E. Goldstein, J. E. Kotar, E. Lauga, F. Nadal

The paper directly measures unsteady microscale Stokes flow by tracking tracer particles around an oscillating particle, revealing phase lag and flow patterns consistent with theoretical predictions.

Computer-assisted segmentation-free analysis for long-term assessment of flagellar beating in free swimming human spermatozoa: the role of emptying calcium stores

G. Corkidi, P. Hernandez-Herrera, F. Montoya, H. Gadelha, A. Darszon

This paper introduces a segmentation-free method to analyze flagellar beating in human spermatozoa over long periods, revealing nonlinear effects of intracellular Ca2+ on beat frequency and amplitude.

The human sperm beats anisotropically and asymmetrically in 3D

H. Gadelha, P. Hernandez-Herrera, F. Montoya, A. Darszon, G. Corkidi

This paper uses 3D imaging and mathematical analysis to show human sperm flagella beat anisotropically and asymmetrically, revealing a novel mechanism that creates the illusion of symmetry in 2D observations.
