CHB‐Induced Immune Zonation Chaos Elicited LXRα‐mediated Lipid Metabolism Disorders in Kupffer Cells to Induce Cancer Stem Cell Formation

open access: yesAdvanced Science, EarlyView.
By profiling the spatiotemporal hepatic landscape of CHB mouse models, the originally peri‐portal localized KCs migrated to the peri‐central in a CXCL9‐CXCR3‐dependent manner, facilitating their interaction with HBV+ hepatocytes. The interaction promoted LMD in KCs through ASGR1‐induced LXRα degradation, which, in turn, induced CSC formation via Stat3 ...

Hierarchical Strain‐Modified Medium‐Entropy Carbide Ceramics Exhibit Exceptional Ablation Resistance up to 2400°C

open access: yesAdvanced Science, EarlyView.
A novel strategy is developed by doping reduced graphene oxide (rGO) into a (HfZrTi)C medium‐entropy ceramic. This induces a hierarchical strain modification mechanism, synergistically inhibiting crack propagation at the microscale and dissipating stress at the mesoscale.

Quality Assessment of Hydrogeomorphological Features Derived from Digital Terrain Models [PDF]

open access: yes, 2008
Digital terrain models (DTM) provide a model for representing the continuous earth elevation surface that can contain errors introduced by the main phases of generation and modelling. Uncertainty of the model is rarely considered by users.
