Radiative corrections are crucial for modern high-precision physics experiments, and are an area of active research in the experimental and theoretical community. Here we provide an overview of the state of the field of radiative corrections with a focus on several topics: lepton-proton scattering, QED corrections in deep-inelastic scattering, and in radiative light-hadron decays. Particular emphasis is placed on the two-photon exchange, believed to be responsible for the proton form-factor discrepancy, and associated Monte-Carlo codes. We encourage the community to continue developing theoretical techniques to treat radiative corrections, and perform experimental tests of these corrections.

Owing to their unique combination of magnetic and optical properties, luminescent polychlorinated radicals are promising candidates for advanced applications in both optoelectronics and quantum technologies. In this study, we employ the lineshape formalism within a computational protocol based on time-dependent density functional theory (TD-DFT) to investigate the excited-state properties of six representative members of this family presenting different sizes and excited-state characters. We explore a wide range of density functionals, applying or not the Tamm-Dancoff approximation (TDA), combined with different vibronic models, namely, the vertical gradient (VG), vertical Hessian (VH), and adiabatic Hessian (AH), as well as dipole moment expansions using the Franck-Condon (FC) and Herzberg-Teller (HT) approximations.

Monte Carlo (MC) simulations are the gold standard for describing various transport phenomena and have largely contributed to the understanding of these processes. However, while their implementation for classical transport governed by exponential step-length distributions is well-established, widely accepted approaches are still lacking for the more general class of anomalous transport phenomena. In this work, a set of rules for performing MC simulations in anomalous diffusion media is identified, which is also applicable in the case of finite-size geometries and/or heterogeneous inclusions.

Coastal waters are among the most ecologically and economically significant ecosystems, yet many regions remain under-monitored due to the limitations of existing monitoring stations and satellite imaging products. This study introduces the Sentinel-3 Coastal Analysis Ready Data (S3CARD) framework, designed to generate gridded, analysis-ready, atmospherically corrected surface reflectance data from Sentinel-3 Ocean and Land Colour Instrument (OLCI) imagery for coastal applications. The framework integrates radiative transfer-based atmospheric correction, adjacency and glint correction, and quality assessment to produce gridded surface reflectance outputs for coastal water analysis.

Accurate determination of the quantum yield (Φf) in scattering media is essential for numerous scientific and industrial applications, but it remains challenging due to re-absorption and scattering-induced biases. In this study, we present a GPU-accelerated Monte Carlo simulation framework that solves the full fluorescence radiative transfer equation (FRTE), incorporating spectrally dependent absorption, scattering, and fluorescence cascade processes. The model accounts for re-emission shifts, energy scaling due to the Stokes shift and implements a digital optical twin of the experimental setup, including the precise description of the applied integrating sphere.
