Automatic Virtual‐to‐real Calibration and Dynamic Registration of Deformable Tissue for Endoscopic Submucosal Dissection

open access: yesAdvanced Intelligent Systems, EarlyView.
During endoscopic submucosal dissection (ESD), the precise and intuitive sensing of target tissues is of crucial importance. Augmented reality (AR), at present, emerges as a powerful solution to offer intuitive guidance. The cover image presents an AR‐assisted ESD procedure.

Discrete-Time Chaotic-Map Truly Random Number Generators: Design, Implementation, and Variability Analysis of the Zigzag Map

open access: yes, 2012
In this paper, we introduce a novel discrete chaotic map named zigzag map that demonstrates excellent chaotic behaviors and can be utilized in Truly Random Number Generators (TRNGs). We comprehensively investigate the map and explore its critical chaotic

Hierarchical Superposition Framework Reveals the Complex Effects of Natural Medicine Formulas

open access: yesAdvanced Intelligent Systems, EarlyView.
A novel hierarchical superposition pharmacological model incorporates the principle of hierarchical structures from physics to simulate the spatiotemporal dynamics of drug combinations, to elucidate the universal law underlying drug combination effects. By modeling cross‐level causal transmission and attenuation, it advances beyond traditional additive

Magnetic Multifunctional Nanoparticles for Effective Targeted Cancer Therapy

open access: yesAdvanced NanoBiomed Research, EarlyView.
To overcome physiological barriers and achieve prolonged tumor retention, core–shell nanoparticles (Fe3O4@SiO2@Au, termed FSA‐NPs) with gold‐decorated surfaces are constructed. FSA‐NPs exhibit strong magnetic resonance imaging (MRI) contrast and potent anticancer effects through the synergistic action of chemotherapy, magnetic targeting, and ...

Isothiourea‐Catalysed Acylative Kinetic and Dynamic Kinetic Resolution of Planar Chiral Paracyclophanols

open access: yesAngewandte Chemie International Edition, Accepted Article.
The development of synthetic methods for the catalytic enantioselective preparation of planar chiral paracyclophane derivaties is of considerable interest to the synthetic community. To date, relatively few successful and effective organocatalytic approaches to this molecular class have been reported.
