Area spectrum of the Schwarzschild black hole
, 1996 We consider a Hamiltonian theory of spherically symmetric vacuum Einstein gravity under Kruskal-like boundary conditions in variables associated with the Einstein-Rosen wormhole throat.

On thin-shell wormholes evolving in flat FRW spacetimes
, 2011 We analize the stability of a class of thin-shell wormholes with spherical symmetry evolving in flat FRW spacetimes. The wormholes considered here are supported at the throat by a perfect fluid with equation of state $\mathcal{P}=w\sigma$ and have a ...

Advanced Science, EarlyView.This study developes a universal colorimetric ICA platform that integrates broad‐spectrum recognition by 4‐mercaptophenylboronic acid with dual signal enhancement—both colorimetric and catalytic—mediated by a biomimetic magnetic nanozyme. This platform, for the first time, enables simple, convenient, ultrasensitive, and simultaneous screening of ...

Advanced Science, EarlyView.Hijacking Host Kinase PIM1: A β‐Coronavirus (OC43) strategy to degrade IFNAR1 and evade antiviral immunity. Human β‐coronaviruses (OC43) exploit the proto‐oncoprotein PIM1 kinase to sabotage innate immunity. Viral RNA/proteins upregulate PIM1, which phosphorylates E3 ligase β‐TrCP1.

Advanced Science, EarlyView.In this study, C‐TAH, as multifunctional nanosheets, is developed with tannic acid and histone aptamer coverage. C‐TAH displays mild cytotoxicity, robust dsDNA and NETs/EETs binding efficiency, and potent antioxidant and antibacterial ability in vitro. C‐TAH treatment ameliorates dysregulated inflammation and restores hearing function in animal models,

A Wearable AI‐Driven Mask with Humidity‐Sensing Respiratory Microphone for Non‐Vocal Communication
Advanced Science, EarlyView.A wearable, plug‐and‐play respiratory microphone—featuring a gold nanoparticle‐based humidity sensor—facilitates voice‐free verbal communication for patients with impaired vocal fold function. Abstract Hoarseness and dysphonia caused by vocal cord conditions or laryngeal surgeries significantly hinder communication and quality of life.
