Fast Dynamic Obstacle Avoidance for Quadruped Robots via Privileged State Estimation and Hierarchical Reinforcement Learning

Yilin Zhang, Jiayu Zeng, Jianan Xie, Weiyang Xu et autres

Avoiding fast, dynamic obstacles is a safety-critical capability for legged robots operating near people and in unstructured environments: the robot must infer an incoming object’s motion from brief noisy observations, generate a collision-free body motion, and execute it within tens of milliseconds. …

Freeze–Thaw Damage Model and Mechanism of Rubber Concrete with Recycled Brick–Concrete Aggregate

Jiayu Zeng, Jiangfeng Dong, Siwei Du, Shucheng Yuan et autres

This study investigated the effects of rubber substitution ratios (0%, 5%, 10%, 15%) on the frost resistance of rubber concrete with recycled brick–concrete aggregate (BRC). The freeze–thaw (F–T) damage model was established and improved, and the damage mechanism was revealed. The results …

Baicalin Restores the Hypoglycemic Effect of Metformin by Regulating the Microbial Imidazole Propionate and Short‐Chain Fatty Acids

Aiting Wang, Zenghui Miao, Binbin Huang, Jiayu Zeng et autres

Gut microbiota dysbiosis is implicated in metformin non-response. This study aimed to investigate whether baicalin, a microbiota-modulating flavonoid derived from Radix Scutellariae, could restore metformin sensitivity and explored the underlying mechanisms. Fecal samples from metformin-treated responders and non-responders were collected and used …

Transcriptional coordination of metabolic reprogramming in chlorogenic- and gamma aminobutyric acid-treated pepper during postharvest storage

Jianwei Zhang, Jiayu Zeng, Jintong Zheng, Hailin Chen et autres

Pepper ( Capsicum annuum L.) fruits rapidly deteriorate during postharvest storage, necessitating innovative preservation strategies. Chlorogenic acid (CGA) and gamma-aminobutyric acid (GABA) are bioactive compounds that extend storage life; however, the molecular mechanisms through which they produce this effect remain largely unexplored. …

Recent Progress in Rationally Engineered Core-Shell Structures of Upconversion Nanoparticles for Luminescence-Enhanced and Versatile Imaging

Sheng Pan, Jiayu Zeng, Changwen Li, Qian Dong et autres

Abstract Near-infrared (NIR)-excited lanthanide-doped upconversion nanoparticles (UCNPs) with core-shell structures present an intriguing system because of their exceptional luminescent properties and wide range of imaging applications. In this review, we establish a nanostructure-engineering framework that systematically correlates luminescence modulation with imaging uses …

Creating a Modular Activatable CRISPR–Cas12a System by Engineering crRNA Scaffold with a Steric Hindrance Effector

Pengfei Liu, Shengli Li, Jiayu Zeng, Meixia Wang et autres

CRISPR-Cas systems inherently lack spatiotemporal control over cleavage events, compromising their accuracy and efficiency in biotechnological applications. Although advances have been made in regulating these systems, developing modular activatable platforms adaptable to diverse stimuli remains challenging. To address this limitation, we developed …
