X-LMC: Cross-View Spatiotemporal Collateral Circulation Scoring from DSA

X‑LMC is a spatiotemporal deep‑learning framework that automatically scores leptomeningeal collateral (LMC) status from time‑resolved biplane digital subtraction angiography (DSA). It uses a DINOv2 backbone to encode spatial frames, a token‑level cross‑view attention module to fuse orthogonal projections, and a recurrent network to model contrast bolus dynamics. On a multicenter dataset of 134 M1‑segment occlusion patients, X‑LMC achieved a Quadratic Weighted Kappa of 0.398 and a macro‑F1 of 0.711, outperforming static and other spatiotemporal baselines and matching clinical inter‑rater agreement.

Knowledge-Guided Cross-Modal Fusion for Adult-to-Pediatric ECG Transfer via Label-Conditioned Contrastive Alignment

arXiv:2607. 15928v1 Announce Type: new Abstract: Adult and pediatric electrocardiogram (ECG) interpretation relies on age-sensitive criteria, and models pretrained mainly on adult ECGs often transfer poorly to pediatric populations when pediatric labels are scarce.

An Elastic Shape Variational Autoencoder for Skeleton Pose Trajectories

The paper introduces the Elastic Shape Variational Autoencoder (ES‑VAE), a geometry‑aware generative model for skeletal pose trajectories that uses the transported square‑root velocity field representation on Kendall's shape manifold to remove rigid transformations and temporal rate variability. ES‑VAE maps sequences to a low‑dimensional latent space via the Riemannian logarithm map and reconstructs them using the exponential map. Experiments on gait analysis for clinical mobility scoring and action recognition on the NTU RGB+D dataset show that ES‑VAE outperforms standard VAEs and several sequence‑modeling baselines.
