Root‐Inspired Microneedle Patch With Interlocked Rigid‐Soft Architecture for High Tissue‐Adaptiveness

Advanced Science, EarlyView.
A root‐inspired microneedle array patch uses lattice‐based mechanical interlocking to unite rigid microneedles with a flexible substrate. The interlocked rigid–soft architecture improves interfacial bonding, supports stable adhesion on curved and wet tissues under dynamic motion, and provides a versatile platform for robust biointerfacing and future ...

Span-dependent comparative analysis of lateral torsional buckling and nonlinear load behaviour in castellated and solid I-beams using analytical and finite element approaches

Materials Research Express
Castellated beams (CB), widely employed in modern construction, offer an improved strength-to-weight ratio and enhanced structural efficiency due to their increased depth and moment of inertia.

TNAP and PHOSPHO1 Function Synergistically to Afford Critical Control Over the Mineralization of the Postnatal Murine Skeleton

Advanced Science, EarlyView.
Biomineralization underpins skeletal development, yet its molecular control remains incompletely understood. Using a novel murine knockout model, this study reveals the essential and complementary roles of PHOSPHO1 and TNAP in postnatal skeletal development.

Study on bearing characteristics of rigid rectangular foundation subjected to horizontal force and torque (H-T)

Shuiwen dizhi gongcheng dizhi
The current design of member foundation only considers horizontal forces (H) and ignores the effect of torque (T), which may lead to torsional failure of the foundation.

Raman Analysis of RNA Nucleotide Strands From SARS‐CoV‐2 Variants and Subvariants: A Step Forward in the Definition of “Raman Genome”

Advanced Science, EarlyView.
Main Raman signals in RNA, related to helical backbone, ribofuranose ring, and nitrogenous bases, are affected by secondary structures that cause hyperchromic effects and significantly alter the Raman intensity. ABSTRACT Raman spectra of RNA nucleotide strands extracted from 20 SARS‐CoV‐2 strains, including the original Japanese isolate, Alpha, Beta ...

Reversible, Chemically Gated FRET via Ligand‐Activated Acceptors

Advanced Science, EarlyView.
Fluorogen binding turns the compact FAST tag into a tunable FRET acceptor, with ligand chemistry programming spectral overlap and excited‐state lifetimes. Fluorescence‐lifetime imaging reads out energy transfer through the shortened donor lifetime, while simply adding or washing out the dye switches FRET on and off, reversibly mapping the supramodular ...

Engineering Evaluation of the Buffeting Response of a Variable-Depth Continuous Rigid-Frame Bridge: Time-Domain Analysis with Three-Component Aerodynamic Coefficients and Comparison Against Six-Component Wind Tunnel Tests

Buildings
Tall-pier, long-span continuous rigid-frame bridges are prone to wind-induced vibration due to their large spans and pier heights; during cantilever erection, the maximum double-cantilever stage has reduced stiffness and buffeting becomes more evident ...
