Discrete analogues of second‐order Riesz transforms

Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.
Abstract Discrete analogues of classical operators in harmonic analysis have been widely studied, revealing deep connections with areas such as ergodic theory and analytic number theory. This line of research is commonly known as Discrete Analogues in Harmonic Analysis (DAHA).

Onset of Fokker-Planck dynamics within a Closed Finite Spin System

, 2012
Relaxation according to Fokker-Planck equations is a standard scenario in classical statistical mechanics. It is however not obvious how such an equilibration may emerge within a closed, finite quantum system.

Tropical TCV as a Process Diagnostic: Connecting Probability to Processes in km–Scale Models Via Moisture Budget Statistics

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Observations show a bimodal frequency distribution in total column vapor (TCV) over tropical oceans, with convective rainfall predominantly produced on the moist side of the frequency minimum between two modal peaks. Here we show a km–scale model of the tropics with explicit convection produces a bimodal TCV distribution, whereas the same ...

The Principle of Minimal Resistance in Non-Equilibrium Thermodynamics [PDF]

, 2015
Analytical models describing the motion of colloidal particles in given velocity fields are presented. In addition to local approaches, leading to well known master equations such as the Langevin and the Fokker-Planck equations, a global description ...

The Dominant Role of the Electron Isotropy Boundary in Controlling Earth's Outer Radiation Belt Electron Lifetimes

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Field‐line curvature scattering (FLCS) is believed to be the primary mechanism forming electron isotropy boundaries (IB) and can rapidly scatter relativistic electrons from the outer radiation belt. However, its direct and quantitative impact on controlling outer belt electron lifetimes has never been directly assessed.

Stochastic Resonance Elucidates the Emergence and Periodicity Transition of Glacial Cycles

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Glacial cycles emerged with a 41‐kyr period after the Pliocene and later intensified with a 100‐kyr period in the mid‐Pleistocene, which were attributed to Earth's orbital variations. However, no significant changes in the orbital forcing were found at the two transitions, and the forcing was too small to drive these cycles. Here, a stochastic

A diffusion approximation and numerical methods for adaptive neuron models with stochastic inputs

Frontiers in Computational Neuroscience, 2016
Characterizing the spiking statistics of neurons receiving noisy synaptic input is a central problem in computational neuroscience. Monte Carlo approaches to this problem are computationally expensive and often fail to provide mechanistic insight. Thus,

Fractional-View Analysis of Space-Time Fractional Fokker-Planck Equations within Caputo Operator

Journal of Function Spaces, 2022
In this article, we investigate the fractional-order Fokker-Planck equations with the help of the Yang transform decomposition method (YTDM). The YTDM combines Yang transform, Adomian decomposition method, and Adomian polynomials into one method.

Equivalence among different formalisms in the Tsallis entropy framework

, 2007
In a recent paper [Phys. Lett. A {\bf335}, 351 (2005)] the authors discussed the equivalence among the various probability distribution functions of a system in equilibrium in the Tsallis entropy framework.
