A neural marking scheme trained with contrastive learning tightens constraints on σ8 by 2.9× and Ωm by 1.8× over classical marks at k_max=0.2 h/Mpc while breaking their degeneracy at the Fisher level.

Forecasts indicate 10-sigma detection for squeezed triangles and 100-sigma for combined shapes in the 21cm-galaxy cross-bispectrum with 100 hours of SKA-Mid interferometric observations on scales 0.2 to 0.9 per Mpc.
MeerKLASS reports successful single-dish HI intensity mapping detections that validate the technique for SKAO cosmology surveys.
Forecasts indicate SKA-Mid AA4 will measure the HI power spectrum at high significance from z~1 to z~3 near k~1 Mpc^{-1}, extending MeerKAT results to constrain HI galaxy properties and galaxy evolution.
Pilot FAST HD² survey reports 339 new HI detections in 10 deg² with 0.45 mJy rms, high DESI optical matching rates, and gas fraction relations consistent with ALFALFA, DINGO, and xGASS.
