Molecular Oncology, EarlyView.This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

, 2012 We demonstrate a simple and robust technique for removal of the carrier wave from a phase-modulated laser beam, using a noninterferometric method that is insensitive to the modulation frequency and instead exploits the polarization dependence of electro ...

Random lasing in a short Er-doped artificial Rayleigh fiber
Results in Physics, 2020 We report on random lasing observed with 5-m-long Er-doped fiber comprising an array of weak fiber Bragg gratings (FBGs) inscribed in the fiber core and uniformly distributed over the whole fiber length.

Molecular Oncology, EarlyView.We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

IEEE Photonics JournalThe backscatter-induced lock-in effect constitutes a primary error source in laser gyroscopes, with the lock-in threshold critically dependent on the magnitude of the backscatter angle. Conventional dual-mirror synchronous frequency stabilization suffers
