Advanced Science, EarlyView.This study reveals that dietary stachyose enriches Butyricimonas virosa, effectively attenuating metabolic dysfunction‐associated steatotic liver disease (MASLD). Mechanistically, B. virosa enhances gut thiamine monophosphate synthesis, which elevates hepatic thiamine pyrophosphate levels.

Programmable Multifunctional Bistable Structures for Energy Transfer and Dissipation
Advanced Science, EarlyView.Utilizing the energy conversion characteristics of asymmetric bistable beams, this study develops a programmable multifunctional system composed of multiple bistable beams for energy transfer and dissipation. The high energy density enables the system to demonstrate potential in transient scenarios such as target delivery and shock absorption ...

Encoding Cumulation to Learn Perturbative Nonlinear Oscillatory Dynamics
Advanced Science, EarlyView.Weak nonlinearities critically shape the long term behavior of oscillatory systems but are difficult to identify from data. A data‐driven framework is introduced to infer governing equations of weakly nonlinear oscillators from sparse and noisy observations.

Application of numerical optimization to the design of advanced supercritical airfoils [PDF]
An application of numerical optimization to the design of advanced airfoils for transonic aircraft showed that low-drag sections can be developed for a given design Mach number without an accompanying drag increase at lower Mach numbers. This is achieved

Advanced Science, EarlyView.An ionic liquid‐based shear‐thickening fluid (ILSTF) exhibits lubricated dynamics from strong shear thickening to impact‐triggered jamming. A persistent nanometric solvation layer around silica governs both the shear thickening saturation in rheology and jamming front propagation under dynamic impact compression.
