Bellman--Shoreline Search in Arbitrary Dimension: Exponential Vector Oscillators, Active Memory, Precession, and Effective Computability

Florentin Koch

We study online search for an unknown affine hyperplane in , for arbitrary fixed finite dimension. Building on a companion self-similar cell reduction and support-fun…

Bellman Search in Arbitrary Finite Dimension: A Self-Similar Cell Theorem and Effective Computability of Planar Shoreline Search

Florentin Koch

A shoreline-search path starts at the origin and must meet an unknown affine line, without knowing either its normal or its distance. We first establish a self-similar reduction th…

Thermal Non-equilibrium Cycles in a Non-eruptive Pseudo-Streamer

Clara Froment, Sophie Masson

Thermal non-equilibrium (TNE) is a well-known thermodynamic mechanism, generally studied in coronal loops. These evaporation and condensation cycles are induced by a quasi-steady a…

Effects of realistic pulse shapes in two-dimensional spectroscopy

M. Russo, R. Gilliot, A. Blech +3

Two-dimensional (2D) spectroscopy is a powerful pump-pump-probe technique for revealing couplings between quantum states and disentangling the different contributions to the optica…

Back Reaction of the Untwisting Solar Corona Scars Sunspots

Chen Xing, Xin Cheng, Guillaume Aulanier +1

The evolution of magnetic fields in the tenuous solar corona is predominantly governed by the motions of the underlying dense photosphere. Despite, coronal magnetic restructuring d…

From Electroculture to Plasma Agriculture: A Three-Century Arc Bridging Bertholon's Legacy with Contemporary Farming Advances

Thierry Dufour

This review traces the historical trajectory of electricity in agriculture, from the earliest observations of electrical phenomena to the emergence of cold plasmas. Looking back to…
