Reliability of Time-Linearized Flutter Predictions Near the Surge Line [PDF]
, 2011 In the context of the flutter analysis of a modern transonic axial compressor two different CFD codes have been compared: based on the same three-dimensional steady solution, the timelinearized Navier-Stokes flow solver TRACE of the German Aerospace ...

Advanced Science, EarlyView.Photobiomodulated microglia release engineered extracellular vesicles that deliver UFL1 to the injured spinal cord. UFL1 competitively binds p53 with MDM2, inhibiting p53 ubiquitination and stabilizing p53 signaling. This dual mechanism simultaneously promotes anti‐inflammatory microglial polarization and directs neural stem cell differentiation toward

Advanced Science, EarlyView.ABSTRACT Mechanophores with mechanochromic properties have attracted significant attention as force‐responsive materials for structural sensing. However, their applications remain mainly limited to qualitative force visualization, as direct and quantitative extraction of mechanical parameters such as stress and strain from mechanochromic responses has ...
