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 Dissipation of Relative Entropy by Diffusion Flows
Entropy, 2016 Given a probability measure, we consider the diffusion flows of probability measures associated with the partial differential equation (PDE) of Fokker–Planck. Our flows of the probability measures are defined as the solution of the Fokker–Planck equation

Advanced Science, Volume 13, Issue 1, 5 January 2026.This study reconstructs the driving force field of fibroblast‐to‐neuron transdifferentiation from sparse single‐cell images by decomposing it into flux and time‐dependent potential gradient, extending the landscape‐flux framework to non‐steady‐state systems.

Archives of Mechanics, 2019 The probabilistic solutions of the elastic stretched beam are studied under the excitation of Kanai–Tajimi ground motion. Finite difference scheme is adopted to formulate the nonlinear multi-degree-of-freedom system about the random vibration of the beam.

Quantum Jumps in Amplitude Bistability: Tracking a Coherent and Invertible State Localization
Annalen der Physik, Volume 538, Issue 1, January 2026.A notable asymmetry is shown to characterize the bistable switching between macroscopic metastable states of light in the strong‐coupling limit of radiation–matter interaction. Transitions from the vacuum to a highly excited state correlate with a highly bunched sequence of emitted photons, while a downward switch to the vacuum involves a coherent ...

Communications on Pure and Applied Mathematics, Volume 79, Issue 1, Page 3-88, January 2026.Abstract We address the problem of regularity of solutions ui(t,x1,…,xN)$u^i(t, x^1, \ldots, x^N)$ to a family of semilinear parabolic systems of N$N$ equations, which describe closed‐loop equilibria of some N$N$‐player differential games with Lagrangian having quadratic behaviour in the velocity variable, running costs fi(x)$f^i(x)$ and final costs gi(

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract Earth's outer radiation belt electron flux is highly variable and can be enhanced by over an order of magnitude over timescales less than one day, as observed during the October 2012 storm. Previous studies of this storm (e.g., Reeves et al., 2013, https://doi.org/10.1126/science.1237743) have invoked local acceleration to explain this ...

Chorus Wave–Driven Electron Dynamics in the Van Allen Belts: From Coherence to Diffusion
AGU Advances, Volume 6, Issue 6, December 2025.Abstract The Van Allen radiation belts contain relativistic electrons trapped by Earth's magnetic field, posing serious risks to spacecraft. Chorus waves are known to accelerate these electrons via resonant interactions, but these interactions are inherently nonlinear and coherent.

Nonlinear Electron Interactions With Intense VLF Waves From Transmitters
Journal of Geophysical Research: Space Physics, Volume 130, Issue 12, December 2025.Abstract The impact on electron lifetimes of nonlinear interactions with the most intense very low frequency (VLF) waves from transmitters has hitherto been neglected in radiation belt codes. Here, we show the presence of a small population of intense wave packets, originating from ground‐based VLF transmitters and reaching 10 mV/m around the magnetic ...
