Advanced Science, EarlyView.This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Multivariate Polynomial Approximation of Powers of the Euclidean Distance Function
, 2007 The polynomial approximation behaviour of the class of functions $F_s: {\bf R}^2 \backslash \{ (x_0, y_0) \} \to {\bf R}, \quad F_s(x,y) = ( (x-x_0)^2 + (y-y_0)^2 )^{-s},\quad s \in (0, \infty),$ is studied in [Bra01].

Advanced Science, EarlyView.The crystalline structure, the atomic numbers of the constituent elementsand the size of MOF crystals each influence their photoluminescence and scintillation properties in distinct ways. Together, these factors provide valuable guidelines for designing systems with optimized performance and tunable timing characteristics, arising from the synergistic ...

A Smart Fluid‐Hydraulic System Based on MRF Valve Control and Its Application in Flexible Grasping
Advanced Science, EarlyView.This study introduces a smart fluid hydraulic system using MRF valve control for flexible gripping. An MRF‐MSV with an integrated excitation coil and micro‐textured damping channels is designed and validated; micro‐texturing increases hydraulic resistance. Coupled with a soft actuator, the MRF‐MSV enables dynamic bending and grasping.

Advanced Science, EarlyView.Frequent sweetened beverage consumption is associated with accelerated biological aging in a large Chinese population. Five gut microbial genera are consistently enriched in both frequent sweetened beverage consumers and individuals with accelerated aging and show significant mediating effects, suggesting a potential microbiota‐related pathway linking ...
