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…
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…
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…
