Second‐Order Degradation Modeling and Multiscale Feature Fusion for High‐Fidelity Segmentation of Low‐Quality Digital Rock Images

open access: yesGeophysical Research Letters
Digital Rock Physics (DRP) is a critical tool for characterizing rock properties and modeling multiphase flow, but segmenting low‐quality (LQ) rock images remains a key challenge due to partial volume blurring.

Targeting the NR1D1–IGF2BP2–V‐ATPase Axis With Hybrid Nanovesicles Restores Macrophage Rhythms to Reverse Sepsis‐Induced Immunosuppression

open access: yesAdvanced Science, EarlyView.
Sepsis disrupts immune‐cell rhythms and weakens bacterial clearance. Biomimetic nanovesicles combining erythrocyte and inflammation‐activated macrophage membranes deliver siNR1D1 to dysfunctional macrophages, restoring the NR1D1–IGF2BP2–V‐ATPase pathway, circadian regulation, phagolysosomal acidification, and antimicrobial defense.

Deep‐Learning‐Based Denoising for Improved Phase Precision in Electron Holography of Electromagnetic Fields in Nanoscale Materials

open access: yesAdvanced Science, EarlyView.
Low‐dose electron holography is limited by shot noise, which buries weak phase signals. HoloDenoiser, a physics‐informed network that works simultaneously in the spatial and frequency domains, locates and protects the holographic sideband while suppressing noise in the hologram.

Natural Product Toosendanin Suppresses the Malignant Development of Skin Melanoma by Targeting BNC2 for Degradation

open access: yesAdvanced Science, EarlyView.
BNC2 exhibits context‐dependent opposing functions across multiple cancer types. This study reveals BNC2 as an oncogenic driver of melanoma proliferation and metastasis through transcriptional activation of PIK3CA. The natural compound TSN simultaneously degrades BNC2 and its oncogenic partner SMAD3 via CRBN‐dependent ubiquitination.

The Adaptive LQ Regulator

open access: yes, 1987
The optimal adaptive control of a linear system in a signal-plus-noise setting with infinite horizon LQ regulator cost is studied. The class of partially observed linear systems for which the certainty equivalence property holds is identified. It is also shown that a linear system is adaptively stabilizable if and only if it is uniformly stabilizable ...

A Huaxian Formula Nanoformulation Confers Protection Against Acute Radiation‐Induced Lung Injury by Targeting Ferroptosis

open access: yesAdvanced Science, EarlyView.
An inhalable, nanoengineered herbal therapy achieves protection against acute radiation‐induced lung injury via self‐assembled nanomicelle‐mediated pulmonary targeting and a previously unrecognized dual mechanism that attenuates oxidative stress while inhibiting ferroptosis in alveolar epithelial cells.

DLST Succinylation‐Mediated Mitochondrial Metabolic Remodeling and Cuproptosis Resistance Promote Malignant Progression of Lung Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
The DLST K409 succinylation mediated by CPT1A promotes OXPHOS and redox homeostasis through regulating enzyme activity, thereby promoting the malignant progression of LUAD. Notably, the succinylation of DLST can enhance the cuproptosis resistance by inhibiting its lipoylation.

Weakly Coordinated Solvent Network‐Induced Ternary Water‐Deficient Eutectic Electrolytes for Low‐Polarization Zn Anodes

open access: yesAdvanced Science, EarlyView.
A water‐deficient ternary eutectic electrolyte employs weakly coordinating solvents to decouple strong solvation interactions, constructing a loose and dynamic solvation network. This optimized solvation structure accelerates Zn2+ transport and interfacial kinetics, promotes robust SEI formation, and ultimately enables highly stable and reversible Zn ...
