A preprint describes a deterministic pipeline that improves the signal-to-noise of faint Jovian radio emissions in Parker Solar Probe archives, compares its patterns with Stokes V data, and screens likely events without becoming a definitive detector.

A preprint comparing optical observations of BlueBird 6 with five earlier satellites found the newer spacecraft was fainter than Block 1 craft and fell well below expectations based on its larger size.

Capra recovered the main large-scale structures in a tested IBEX-Hi dataset and closely preserved the rates, intensities and reconstructed signal checked by the analysis. The authors considered Nside = 64 sufficient for that dataset under the stated convergence criterion, while benchmark results varied by kernel setting.

A laboratory experiment reports pairs of attosecond soft-X-ray pulses with adjustable timing and evidence that their relative phase could be tuned. The study characterizes the light source and its diagnostics; it does not report a direct molecular or quantum-system control experiment.
