Search with home returns provides advantage under high uncertainty

A Pal, Ł Kuśmierz, S Reuveni - Physical Review Research, 2020 - APS
Many search processes are conducted in the vicinity of a favored location, ie, a home, which
is visited repeatedly. Foraging animals return to their dens and nests to rest, scouts return to …

Computational roles of intrinsic synaptic dynamics

G Shimizu, K Yoshida, H Kasai, T Toyoizumi - Current opinion in …, 2021 - Elsevier

Thermodynamics of superdiffusion generated by Lévy–Wiener fluctuating forces

Ł Kuśmierz, B Dybiec, E Gudowska-Nowak - Entropy, 2018 - mdpi.com
Scale free Lévy motion is a generalized analogue of the Wiener process. Its time derivative
extends the notion of “white noise” to non-Gaussian noise sources, and as such, it has been …
