Ensuring flexible optical intubation skills using a portable virtual reality simulator – a validation study

Mingjuan Sun, Xiaomei Guo, Qiong Qin, Huimin Liu et autres

BACKGROUND: Anesthesiologists must be able to perform flexible optical intubation (FOI) in challenging cases, but the skill is difficult to master and cannot be adequately taught using the traditional apprenticeship model. Mastery learning simulation-based training ensures that all trainees acquire basic competence …

Neuronal subtype governs amyloid structure, cellular response, and cognitive outcome in genetically targeted APP mouse models

Gabriella Perez, Zoe Lai, George A. Edwards, Jacob Dundee et autres

Pathological heterogeneity is increasingly appreciated in Alzheimer’s disease, yet we do not know how distinct aggregate conformations arise or influence cognitive outcomes. In an amyloid mouse model, we found that different brain regions formed structurally distinct Aβ deposits, prompting us to test …

TopoPerception: A Shortcut-Free Evaluation of Global Visual Perception in Large Vision-Language Models

Wenhao Zhou, Hao Zheng, Rong Zhao

Large Vision-Language Models (LVLMs) typically align visual features from an encoder with a pre-trained Large Language Model (LLM). However, this makes the visual perception module a bottleneck, which constrains the overall capabilities of LVLMs. Conventional evaluation benchmarks, while rich in visual semantics, …

Broadband-Enhanced Terahertz Metasurface Biosensor Enables Molecular Fingerprint Trace Detection via Single-Shot Acquisition

Qiang Niu, Kai He, Rong Zhao, Yinong Xie et autres

Enhancing light–matter interactions to reveal the fingerprint properties of trace molecules is of great significance for terahertz (THz) absorption spectroscopy, which provides vital information about inter- and intramolecular vibrations. The construction of gradient narrow-resonance metasurfaces offers an effective solution to amplify the …
