A comprehensive review on adaptive plasticity and recovery mechanisms post‐acquired brain injury

open access: yesNeuroprotection, EarlyView.
This figure illustrates the dynamic process of neurogenesis following brain injury, focusing on the roles of neural stem and progenitor cells at the injury site. Key mechanisms include axonal sprouting, synaptogenesis, dendritic remodeling, and brain‐derived neurotrophic factor signaling via TrkB receptors.

ReliOcc: Towards Reliable Semantic Occupancy Prediction via Uncertainty Learning [PDF]

open access: yesarXiv
Vision-centric semantic occupancy prediction plays a crucial role in autonomous driving, which requires accurate and reliable predictions from low-cost sensors. Although having notably narrowed the accuracy gap with LiDAR, there is still few research effort to explore the reliability in predicting semantic occupancy from camera.
