Turning angle analysis reveals hidden anisotropies in the anomalous diffusion of molecules in live cells
Michał Balcerek, Adrian Pacheco-Pozo, Agnieszka Wyłomańska +1
Molecular motion within living cells provides a window into the physical principles underlying intracellular organization and transport. Yet a fundamental limitation remains: measu…
Oscillatory Active Brownian Motion: A Minimal Model for Sperm Dynamics
Adrian Pacheco-Pozo, Arturo Matamoros Volante, Pilar Ameijeiras +2
Active biological microswimmers typically combine persistent self-propulsion with cyclic motion generated by flagellar or ciliary beating. However, standard active Brownian motion…
Two-dimensional fractional Brownian motion: Analysis in time and frequency domains
MichaÅ Balcerek, Adrian Pacheco-Pozo, Agnieszka WyÅomaÅska +2
This article introduces a novel construction of the two-dimensional fractional Brownian motion (2D fBm) with dependent components. Unlike similar models discussed in the literature…
Analytical results for the distribution of first return times of non-backtracking random walks on configuration model networks
Dor Lev-Ari, Ido Tishby, Ofer Biham +2
We present analytical results for the distribution of first return (FR) times of non-backtracking random walks (NBWs) on undirected configuration model networks consisting of n…
Objective comparison of methods to decode anomalous diffusion
Gorka Muñoz-Gil, Giovanni Volpe, Miguel Angel Garcia-March +31
Deviations from Brownian motion leading to anomalous diffusion are found in transport dynamics from quantum physics to life sciences. The characterization of anomalous diffusion fr…
Quantitative evaluation of methods to analyze motion changes in single-particle experiments
Gorka Muñoz-Gil, Harshith Bachimanchi, Jesús Pineda +33
The analysis of live-cell single-molecule imaging experiments can reveal valuable information about the heterogeneity of transport processes and interactions between cell component…
