Inferring Tree Structure with Hidden Traps from First Passage Times
Fabian H. Kreten, Ludger Santen, Reza Shaebani
Tracking the movement of tracer particles has long been a strategy for uncovering complex structures. Here, we study discrete-time random walks on finite Cayley trees to infer key…
Convective Flows in Sheared Packings of Spherical Particles
Mehran Erfanifam, Mahnoush Madani, Reza Shaebani +1
Understanding how granular materials respond to shear stress remains a central challenge in soft matter physics. We report direct observations of persistent granular convection in…
Transport-Generated Signals Uncover Geometric Features of Evolving Branched Structures
Fabian H. Kreten, Ludger Santen, Reza Shaebani
Branched structures that evolve over time critically determine the function of various natural and engineered systems, including growing vasculature, neural arborization, pulmonary…
Microtubule polymerization generates microtentacles important in circulating tumor cell invasion
Lucina Kainka, Reza Shaebani, Kathi Kaiser +3
Circulating tumor cells (CTCs) have crucial roles in the spread of tumors during metastasis. A decisive step is the extravasation of CTCs from the blood stream or lymph system, whi…
Geometry-Driven Segregation in Periodically Textured Microfluidic Channels
Fatemeh S. Ahmadi, Hossein Hamzehpour, Reza Shaebani
We investigate the transport dynamics of elongated microparticles in microchannel flows. While smooth-walled channels preserve the dependence of particle trajectories on initial or…
Tracking the Morphological Evolution of Neuronal Dendrites by First-Passage Analysis
Fabian H. Kreten, Barbara A. Niemeyer, Ludger Santen +1
A high degree of structural complexity arises in dynamic neuronal dendrites due to extensive branching patterns and diverse spine morphologies, which enable the nervous system to a…
