A dual-motor drive system for scraper conveyor

Gong-kuang zidonghua, 2022
Current scraper conveyors with permanent magnet synchronous motors often improve their efficiency by updating the mechanical structure of their drive systems, few efforts are made to optimize the control of permanent magnet synchronous motors. This paper fills the gap by involving maximum torque per ampere (MTPA) and flux-weakening controls to improve ...

Genetic Control of Tissue Remodeling by a Non‐Coding SNP in ITGA8 Explains Carotenoid‐Based Color Polymorphism in Marine Mollusks

Advanced Science, EarlyView.
In this study, the orange‐muscle giant abalone (Haliotis gigantea) is used as a model to identify a non‐coding SNP that disrupts the interaction between ITGA8 pre‐mRNA and the splicing factor ILF2, leading to altered ITGA8 splicing. These splicing changes promote carotenoid accumulation in abalone muscle through the regulation of tissue remodeling ...
