Advanced Science, EarlyView.The concept of high‐dimensional EM modulation using the STMA for physical layer secure communication is illustrated in figure. The STMA consists of a series of programmable unit cells, with 1‐bit reconfigurable phase states (0/π). The STMA is excited by a monochromatic continuous wave (CW) at frequency fc and controlled by a field‐programmable gate ...

Advanced Science, EarlyView.This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

Precipitation Induced Signatures in SAR Images [PDF]
, 2009 Active microwave SAR imaging of the Earth’s surface is commonly considered to be of all weather capability. However, as the operating frequencies of SAR-systems are increasing, visible image distortions due to heavy precipitation in SAR-images are ...

Advanced Science, EarlyView.This study elucidates the phase transition pathway of surface‐engineered perovskite films. During spin‐coating, n = 1 2D perovskite dominantly forms, while subsequent annealing drives OA+ release and induces conversion to higher n‐value 2D phases.

Deltacoronavirus Modulates circRNA cGLIS3 Metabolism to Evade Host Antiviral Response
Advanced Science, EarlyView.This study reveals that both deltacoronavirus nucleocapsid protein and host RNA binding protein IGF2BP2 promote circular RNA GLIS3 (cGLIS3) biogenesis by binding to GLIS3 pre‐mRNA. The m6A modification‐mediated cGLIS3‐IGF2BP2 interaction weakens RNase L‐mediated degradation of cGLIS3 while facilitates a ubiquitin‐dependent degradation of IGF2BP2, thus ...
