Bionic design and optimisation of a mechanical model of the knee-tibia-heel of a car crash dummy

Yuechen Ji, Zhixin Liu, Hai Liu, Zhengqi Fan et autres

The biomechanical performance of crash dummies is crucial for assessing vehicle safety and occupant protection. In traffic accidents, the Knee-Tibia-Heel (KTH) of the front-seat occupants experiences axial forces, causing tibial fractures, ankle damage, and knee trauma. However, dummy responses in these regions …

VvCRY2 mediates blue light signaling to regulate grape anthocyanin biosynthesis via the VvCOP1-VvHY5 signaling cascade

Tianyu Dong, Shaonan Li, Yanhua Ren, Peian Zhang et autres

Blue light enhances anthocyanin accumulation in grape berries, yet the molecular mechanisms underlying this photoreceptor-mediated process remain partially elucidated. ‘Kyoho’ grapevines were subjected to various light treatments, including monochromatic blue and red light (blue, red, or white) and mixed red-blue light treatments …

Enhancement of carrimycin production in Streptomyces spiramyceticus 54-IA by the reporter-guided selection method with traditional mutagenesis

K Li, Jianlu Dai, Yue Chang, Tianyi Hao et autres

Carrimycin, a new drug approved in recent years, is produced by recombinant Streptomyces spiramyceticus harboring a heterogeneous 4″-O-isovaleryltransferase gene (ist). The regulatory gene bsm42 plays a crucial role in activation of carrimycin biosynthesis, its high expression can improve the carrimycin production. The …

A Novel Method to Characterize the Damping Capacity of EPDM/CIIR Blends Using Vibrating Rubber Balls

Zhixin Liu, Kai Wang, Yongqiang Wu, Hanxiao Zhang et autres

An experimental device fixed with a laser displacement sensor was assembled to investigate the rebound behaviors and damping mechanism of rubber balls prepared with ethylene-propylene-diene monomer (EPDM)/chlorinated butyl rubber (CIIR) blends. The result showed that a prediction model was proposed to characterize …

A Novel Method to Characterize the Damping Capacity of EPDM/CIIR Blends Using Vibrating Rubber Balls

Zhixin Liu, Kai Wang, Yongqiang Wu, Hanxiao Zhang et autres

The rebound behaviors of rubber balls based on ethylene-propylene-diene monomer (EPDM) / chlorinated butyl rubber (CIIR) blends were investigated systematically. A novel method was proposed to characterize the damping capacity of the EPDM/CIIR blends. The damping capacity can be represented by the …

Enhancement of Carrimycin Production Via Traditional Mutagenesis with Metabolic Engineering in Streptomyces Spiramyceticus 54IA

Kemeng Li, Jianlu Dai, Juanjuan Liu, Tianyi Hao et autres

Abstract Background: Carrimycin is a new approved class I antibiotic in China. The novel carrimycin producing strain, Streptomyces spiramyceticus 54IA, was constructed by CRISPR-Cas9 editing system without insertion of antibiotics resistant gene. The problem of low yield limits this strain in large …
