Advanced Science, EarlyView.Tightly focused laser irradiation can accumulate tubulin proteins at/around the laser focus, which leads to the formation of highly ordered microtubule assemblies. The assemblies can exhibit various dynamic behaviors such as radial motion, bundling, and flagella‐like rotation with motor protein and chemical energy, highlighting as a unique tool for ...

NFYB Integrates Hormonal Signals into Tissue Allometry by Promoting Protein Biosynthesis
Advanced Science, EarlyView.In the American cockroach, NFYB acts as a spatiotemporin that translates distinct hormonal cues into tissue‐specific allometry. Juvenile hormone activates NFYB in the early fat body, while 20‐hydroxyecdysone induces it in late wing pads. NFYB then promotes protein biosynthesis via core translational machinery, driving differential growth across the ...

A Strong Lewis Acidic Diethylsilylium Catalyst for Direct Sulfonamidation of Challenging Ketones
Advanced Science, EarlyView.Low‐substitution‐order silylium ions (R2HSi+) exhibit exceptional Lewis acidic activity. We report diethylsilylium‐catalyzed reductive sulfonamidation of functionalized ketones to access β‐amino esters. The in situ generated ion pair shows enhanced reactivity, with diethylsilane serving as both reductant and precatalyst. The developed protocol proceeds

The blurred cut-off frequency of acoustic horns
Archives of Acoustics, 2016 On the basis of discussion of the Webster equation the conditions and possibilities of a blurred cut-off frequency for horns of arbitrary geometry were analyzed. The transmission properties of horns in the blurred region were discussed.
