Bifunctional Molecular Switches in Fused Diarylethene–Rhodamine Systems
ChemPhotoChem, Volume 10, Issue 2, February 2026.Spectroscopic and time‐dependent density‐functional theory studies show that these novel rhodamine‐based diarylethene (DAE) compounds display intense UV absorption, undergo reversible two‐step protonation involving triazole and rhodamine units, and respond selectively to acid, base, and metal ions.

Meson resonances in forward-angle π+π− photoproduction
Physics Letters B, 2019 Assuming that the π+π− photoproduction at forward angles and high energies is dominated by one pion exchange we calculate the π+π− mass distributions for low partial waves.

Nitric oxide supersaturation in the surface waters of the oligotrophic Atlantic Ocean
Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.Abstract Atmospheric nitric oxide (NO) is a pollutant and climate‐relevant trace gas. Dissolved NO accumulates in the surface ocean and therefore the ocean is a natural source of atmospheric NO. It is generally assumed that NO in the surface ocean is produced photochemically from nitrite (NO2−).

An Investigation of the Hard Contribution to phi Photoproduction
, 1999 We investigate the possibility that the process of phi photoproduction may have a significant hard perturbative QCD component. This suggestion is based on a study of the energy dependence of the forward phi photoproduction cross section followed by a ...

Evolution of Ionospheric Ion Upflow Flux During the April 2023 Geomagnetic Storm
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract We study the impact of the evolving magnetosphere‐ionosphere‐thermosphere system on upward ion fluxes during the 23–24 April 2023 geomagnetic storm. This storm has a “double‐dip” structure where two southward IMF Bz ${\mathrm{B}}_{z}$ periods cause two dips in the SYM‐H index.

Ultra-peripheral collisions and hadronic structure
, 2017 Ultra-peripheral collisions are the energy frontier for photon-mediated interactions, reaching, at the Large Hadron Collider (LHC), $\gamma-p$ center of mass energies five to ten times higher than at HERA and reaching $\gamma\gamma$ energies higher than ...

Dressing the electromagnetic nucleon current [PDF]
, 2011 A field-theory-based approach to pion photoproduction off the nucleon is used to derive a microscopically consistent formulation of the fully dressed electromagnetic nucleon current in an effective Lagrangian formalism.

Assessment of the Generation of Traveling Ionospheric Disturbances by Solar Terminators
Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.Abstract The generation of traveling ionospheric disturbances (TIDs) near solar terminators has been predicted, and several studies have reported the detection of TIDs associated with sunrise. However, there are also observations that do not show TID signatures at sunrise.

J/ψ photoproduction in ultra-peripheral Pb-Pb and p-Pb collisions with the ALICE detector
EPJ Web of Conferences, 2014 Ultra-relativistic heavy ions generate strong electromagnetic fields which offer the possibility to study gamma-gamma, gamma-nucleus and gamma-proton processes at the LHC in ultra-peripheral Pb-Pb and p-Pb collisions.
