UAV High-Speed Target Reconnaissance and Deblurring
IEEE AccessIn military operations, the detection of enemy targets by reconnaissance aircraft usually results in obvious motion blur in imaging due to the rapid movement or position change of the target, which poses a challenge for accurate target identification. To

Enhancing Maturation of Human Neuromuscular Organoids via Electrical Stimulation
Advanced Science, EarlyView.A framework for on‐demand and non‐invasive exposure of human neuromuscular organoids (NMOs) to electrical stimuli is established to promote their maturation. The robustness and effectiveness of different stimulation regimes are evaluated via thorough characterization of organoid tissue structure and contraction capacity. Chronic electrical stimulation,

The Mind From Within: Visceral Roots of Human Cognition
Advanced Science, EarlyView.The physiological activity of visceral organs, such as the heart, the lungs, and the gut, is surprisingly linked to many sophisticated mental operations, such as remembering the past, being aware of ourselves, making choices, and forging social bonds.

Ethical Precision in Nanoscale Brain Interfacing
Advanced Science, EarlyView.As brain interfaces approach the nanoscale, precision no longer only measures—it knows, predicts, and potentially reshapes the mind. This work argues that traditional ethics fails under such conditions and proposes a shift toward continuous, operation‐based governance using the recovery–discovery framework to track, constrain, and responsibly steer ...

Motion De-blurring Using a Blur Model
The Journal of the Institute of Image Information and Television Engineers, 2005 We present a variational motion de-blurring method that minimizes the regularized energy functional defined with a spatially variant model of motion blurs. Unlike spatially invariant image blurs, minimization cannot be achieved in a closed non-iterative way, and we therefore need to derive its iterative algorithm.

Advanced Science, EarlyView.This study presents an anatomical landmark‐guided DRL framework for autonomous wireless capsule endoscopy navigation. Using a lightweight edge‐contour‐depth fusion module, it achieves over 97% coverage across diverse gastric anatomies. To ensure reliability, a two‐stage sim‐to‐real pipeline with an adaptive dynamic programming controller mitigates ...

Advanced Science, EarlyView.Stem cell differentiation follows a conserved surface condensate trajectory: H3K27ac super enhancers nucleate large RNA polymerase II clusters that grow and unfold before transcriptional activity disperses them. This work reveals how biophysical forces at enhancer surfaces dynamically build and dismantle stem cell transcription hubs, reshaping cell ...

Optical Windows for Transcranial Brain Imaging in Living Mice: Skull Thinning, Clearing, and Beyond
Advanced Science, EarlyView.Longitudinal, noninvasive in vivo imaging is crucial for studying brain physiology. Advances in transcranial optical windows and multiphoton microscopy have improved imaging depth, but their performance often deteriorates over time. This work investigated various transcranial window approaches and found that skull regrowth limits image quality.
