The Condenser Problem

open access: yesThe Annals of Probability, 1977
The condenser theorem in classical potential theory is studied within the framework of Markov processes and probabilistic potential theory. The condenser charge is expressed in terms of successive balayages of a capacitary measure.

To condense or not to condense: Wnt regulation by centrosome-nucleated biomolecular condensates

open access: yesProceedings of the National Academy of Sciences, 2022
Colorectal cancer is the third leading cause of cancer deaths worldwide, and, thus, understanding genetic changes driving cancer development and progression is critical. A key breakthrough occurred 31 y ago when scientists cloned the tumor suppressor gene adenomatous polyposis coli (APC), mutated in families with a predisposition to colon cancer ...

Memory Re-Condensation

open access: yes, 2023
This paper reveals a phenomenon of memory in dropwise condensation in open air. After a first condensation process and complete evaporation of the condensed droplets, further condensations proceed with droplets nucleating at the very places where former ...
