T cell migration, search strategies and mechanisms
T cell migration is essential for T cell responses; it allows for the detection of cognate antigen
at the surface of antigen-presenting cells and for interactions with other cells involved in the …

Intermittent search strategies
This review examines intermittent target search strategies, which combine phases of slow
motion, allowing the searcher to detect the target, and phases of fast motion during which …

Description of an ecological niche for a mixed local/nonlocal dispersal: an evolution equation and a new Neumann condition arising from the superposition of …
S Dipierro, E Valdinoci - Physica A: Statistical Mechanics and its …, 2021 - Elsevier
We propose here a motivation for a mixed local/nonlocal problem with a new type of
Neumann condition. Our description is based on formal expansions and approximations. In …

New insights into pelagic migrations: implications for ecology and conservation
Highly pelagic large marine vertebrates have evolved the capability of moving across large
expanses of the marine environment; some species routinely move across entire ocean …

Assessing Lévy walks as models of animal foraging
The hypothesis that the optimal search strategy is a Lévy walk (LW) or Lévy flight, originally
suggested in 1995, has generated an explosion of interest and controversy. Long-standing …

The topography of the environment alters the optimal search strategy for active particles
In environments with scarce resources, adopting the right search strategy can make the
difference between succeeding and failing, even between life and death. At different scales …

Molecular mechanism of long-range diffusion in phospholipid membranes studied by quasielastic neutron scattering
The motion of phospholipids has previously been studied on many time scales due to the
significance for living cells and technological applications. The motions on a pico-to …

Asymptotic analysis of first passage time problems inspired by ecology
A hybrid asymptotic–numerical method is formulated and implemented to accurately
calculate the mean first passage time (MFPT) for the expected time needed for a predator to …

Sampling rate and misidentification of Lévy and non‐Lévy movement paths
MJ Plank, EA Codling - Ecology, 2009 - Wiley Online Library
A large number of empirical studies have attributed Lévy search patterns to the foraging
movements of animals. Typically, this is done by fitting a power‐law distribution with an …
