A professional training simulator for skill acquisition in ultrasound-guided lumbar facet syndrome intervention: design and educational evaluation

IntroductionUltrasonography (US) plays a central role in modern diagnostic and interventional medicine, particularly in the management of facet-origin chronic low back pain, a highly prevalent condition in industrialized societies. However, its clinical effectiveness depends largely on the level of specialist training, requiring advanced skills in probe manipulation, sonoanatomy interpretation, brain-hand-eye coordination, and safe planning of […]

ChatGPT-4o with faculty guidance outperforms AI-only and traditional learning in ultrasonography training: a randomized trial

BackgroundUltrasonography training for residents is challenging owing to its operator-dependent nature and difficulties in mastering subtle image interpretation. Multimodal large language models like ChatGPT-4o enable efficient knowledge retrieval but show marked limitations in static ultrasonography image analysis.MethodsIn this prospective, single-centre randomized controlled trial, 45 first-year ultrasonography residents were randomly allocated to control (traditional resources), AI-only […]

The Mirror Design Pattern: Strict Data Geometry over Model Scale for Prompt Injection Detection

arXiv:2603.11875v1 Announce Type: cross Abstract: Prompt injection defenses are often framed as semantic understanding problems and delegated to increasingly large neural detectors. For the first screening layer, however, the requirements are different: the detector runs on every request and therefore must be fast, deterministic, non-promptable, and auditable. We introduce Mirror, a data-curation design pattern that […]

Slow-Fast Inference: Training-Free Inference Acceleration via Within-Sentence Support Stability

arXiv:2603.12038v1 Announce Type: cross Abstract: Long-context autoregressive decoding remains expensive because each decoding step must repeatedly process a growing history. We observe a consistent pattern during decoding: within a sentence, and more generally within a short semantically coherent span, the dominant attention support often remains largely stable. Motivated by this observation, we propose Slow-Fast Inference […]
