Abstract Although aggregation-induced electrochemiluminescence (AIECL) holds significant promise for signal amplification, its practical advancement is impeded by the intrinsically low ECL efficiency of conventional AIEgens and the stochastic nature of aggregate formation. Herein...

Nonlinear dynamic modeling and parameter identification of air springs in the ultra-low frequency range considering thermal hysteresis

The nonlinear dynamic performance of a constrained rolling-lobe air spring (CRLAS) is measured using a servo-controlled hydraulic test rig. Experimental results indicate that in the ultra-low frequency range (0.002–1 Hz), the dynamic stiffness increases sharply, while the loss an...

When to stop? assessing the appropriate cycle of ovulation induction with timed intercourse in letrozole- or clomiphene citrate-sensitive polycystic ovary syndrome

To study how many cycles of ovulation induction with timed intercourse were appropriate for PCOS patients sensitive to letrozole or clomiphene citrate. A prospective study. A total of 655 women with PCOS were included who underwent 2633 cycles with ovulation induction followed by...

Transcytosis-Guided Intestinal Absorption of Ultrasmall Gold Nanoparticles for Lymphatic Entry into Systemic Circulation

Abstract The intestinal epithelial barrier severely impedes absorption of orally administered nanoparticles. Herein, we designed ultrasmall PEPT1-targeted gold nanoparticles (GP-AuNPs) using a dual-ligand strategy: Gly-Sar peptides for PEPT1 recognition on intestinal epithelial c...

Active suspension preview control via deep reinforcement learning with hybrid synchronizing policy and hierarchical road perception

The rapid advancement of vehicle electronic control systems has provided favorable support for enhancing the dynamic response and control performance of suspension systems. Conventional control strategies based on suspension state feedback are limited in their active adjustment c...

Dirac‐Point‐Assisted Topological Charge Exchange in Dual‐Wavelength BIC Vortex Microlasers

ABSTRACT On‐chip lasers that emit wavelength‐multiplexed structured light are important in integrated photonics. Bound states in the continuum (BICs) provide high‐quality resonances with radiation topology, enabling vortex lasing at multiple wavelengths. However, the topological...

Inclined pullout performance of helical anchors for floating offshore wind turbines: A geometry-driven mechanism shift

Helical anchors serve as critical mooring foundations for floating offshore wind turbines (FOWTs) under complex inclined pullout loads. However, the effect of anchor geometric stiffness on the inclined load-bearing mechanism remains poorly understood. This study employs three-dim...
