Modeling the EMIC Wave‐Induced Acceleration of Energetic Protons in the Io Footprint Tail

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Io footprint tail (FPT) region is crucial for studying the interactions between Io and Jupiter's magnetosphere. In this region, Juno spacecraft observed significant acceleration of energetic protons, concurrently with electromagnetic ion cyclotron (EMIC) waves below the proton gyro‐frequency.

Stochastic analysis of ocean wave states with and without rogue waves

open access: yesNew Journal of Physics, 2014
This work presents an analysis of ocean wave data including rogue waves. A stochastic approach based on the theory of Markov processes is applied. With this analysis we achieve a characterization of the scale-dependent complexity of ocean waves by means ...

A hybrid algorithm for solving fractional Fokker-Planck equations arising in physics and engineering

open access: yesJournal of New Results in Science, 2022
In this work, we proposed a hybrid algorithm to approximate the solution of Conformable Fractional Fokker-Planck Equation (CFFPE). This algorithm comprises of unification of two methods named Fractional Wave Transformation Method (FWTM) and Differential ...

Diffusion Coefficients for Resonant Relativistic Wave‐Particle Interactions Using the PIRAN Code

open access: yesEarth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Quasilinear diffusion coefficients can be used to model the response of charged particles to resonant wave‐particle interactions. The calculation of these coefficients is sufficiently complicated and arduous to render it prohibitive to many potential users, because of the expense in time spent developing the code.

Diffusion in Phase Space as a Tool to Assess Variability of Vertical Centre-of-Mass Motion during Long-Range Walking

open access: yesPhysics, 2023
When a Hamiltonian system undergoes a stochastic, time-dependent anharmonic perturbation, the values of its adiabatic invariants as a function of time follow a distribution whose shape obeys a Fokker–Planck equation.

Short and long time behavior of the Fokker-Planck equation in a confining potential and applications [PDF]

open access: yes, 2005
We consider the linear Fokker-Planck equation in a confining po- tential in space dimension d ≥ 3. Using spectral methods, we prove bounds on the derivatives of the solution for short and long time, and give some applica- tions.

Medium‐Range Predictability of the Wintertime Bering Sea Ice Edge Using Linear Inverse Modeling

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Beginning in autumn, sea ice expands into the southern Bering Sea, where it remains until spring. In winter, some commercial stocks, particularly crabs, thrive in ice‐infested areas, necessitating short‐lead forecasts of the ice edge for fishers.

Numerical Simulation for Solute Transport in Fractal Porous Media [PDF]

open access: yes, 2004
A modified Fokker-Planck equation with continuous source for solute transport in fractal porous media is considered. The dispersion term of the governing equation uses a fractional-order derivative and the diffusion coefficient can be time and scale ...

Numerical Solution of the Time-Fractional Fokker-Planck Equation with General Forcing [PDF]

open access: yesSIAM Journal on Numerical Analysis, 2015
We study two schemes for a time-fractional Fokker-Planck equation with space- and time-dependent forcing in one space dimension. The first scheme is continuous in time and is discretized in space using a piecewise-linear Galerkin finite element method ...

Improved estimation of Fokker-Planck equations through optimisation

open access: yes, 2007
An improved method for the description of hierarchical complex systems by means of a Fokker-Planck equation is presented. In particular the limited-memory Broyden-Fletcher-Goldfarb-Shanno algorithm for constraint problems (L-BFGS-B) is used to minimize ...
