Atroposelective Construction of Axially Chiral Tetraarylethenes Via NHC‐Catalyzed Desymmetrization
Advanced Science, EarlyView.We report the first NHC‐catalyzed atroposelective synthesis of axially chiral TAEs via oxidative desymmetrization of prochiral TAE dialdehydes. This catalytic strategy operates under mild conditions and accommodates a broad range of phenolic and nitrogen nucleophiles, delivering diverse axially chiral TAEs in good yields and up to 99% ee.

Metabolism‐Based Biomarkers for Rapid Phenotypic Antibiotic Susceptibility Testing
Advanced Science, EarlyView.Metabolic differences emerging after antibiotic exposure provide rapid phenotypic signals of susceptibility and resistance. This review summarizes metabolic biomarkers for rapid phenotypic AST, associated with nutrient uptake, respiratory activity, metabolic reprogramming, and enzymatic function. ABSTRACT The accelerating global crisis of antimicrobial

Pilot evaluation of sailplane handling qualities [PDF]
The evaluation sailplanes were found generally deficient in the area of cockpit layout. The pilots indicated general dissatisfaction with high pitch sensitivity especially when coupled with inertially induced stick forces.

Advanced Science, EarlyView.RNA structural profiling of Turnip Yellow Mosaic Virus by DMS‐MaPseq and DREEM analyses uncover that viral genome‐wide RSS is highly complicated and heterogeneous, with alternative RSSs widely distributed across the genome. Notably, the viral 3’ tRNA‐like structure adopts alternative conformations in vivo.

Observations of the Growth and Decay of Stall Cells during Stall and Surge in an Axial Compressor
International Journal of Rotating Machinery, 2017 This research investigated unsteady events such as stall inception, stall-cell development, and surge. Stall is characterized by a decrease in overall pressure rise and nonaxisymmetric throughflow.

Advanced Science, EarlyView.This study elucidates the mechanisms of subcellular multidimensional collapse in exhausted T cells. By specifically targeting the nucleus, mitochondria, and endoplasmic reticulum, strategic interventions can effectively remodel the compromised organelle network. This integrated approach drives comprehensive T cell resuscitation, ultimately establishing

The development of CFD methods for rotor applications [PDF]
The optimum design of the advancing helicopter rotor for high-speed forward flight always involves a tradeoff between transonic and stall limitations. However, the preoccupation of the rotor industry was primarily concerned with stall until well into the
