A 4B grounding foundation model achieves state-of-the-art visual grounding, outperforming larger models and boosting downstream robotic and autonomous driving performance by up to 24.8% in OOD settings.

Conformal structures on the hemisphere strictly collapse to the standard round metric under vanishing interior $\sigma_k$-curvature and constant boundary $\mathcal{B}_k$-curvature, closing a major rigidity question in fully nonlinear conformal geometry.

Sentiment in social-media conversations is significantly influenced by discourse moves, with specific interventions capable of mitigating negativity or amplifying hostility.

Autoregressive image and video generators can get a surprising boost in quality *without* retraining, just by steering them towards outputs that better support their own past creations.
