Mean first-passage times of non-Markovian random walkers in confinement
The first-passage time, defined as the time a random walker takes to reach a target point in
a confining domain, is a key quantity in the theory of stochastic processes 1 . Its importance …

CNT effective interfacial energy and pre-exponential kinetic factor from measured NaCl crystal nucleation time distributions in contracting microdroplets
Nucleation, the birth of a stable cluster from a disorder, is inherently stochastic. Yet up to date,
there are no quantitative studies on NaCl nucleation that accounts for its stochastic nature. …
