Summary: With the rapid development of aerospace, the lack of digital monitoring and detection in the current manufacturing process leads to low efficiency and inconsistent quality of large complex curved workpieces. To address this issue, a framework of a monitoring system based on digital twin technology is proposed, focusing on the low degree of virtual visualization and insufficient monitoring ability in large complex surface machining. By studying key technologies such as virtual twin model construction, multi-source data acquisition and transmission, and virtual-real mapping relationship construction, a digital twin monitoring system for large complex surface machining is developed. The feasibility and effectiveness of the system are verified through a real scene, providing a reference for monitoring the machining process of large complex curved workpieces.

Summary: This article proposes a strategy for automating and controlling multi-step polishing chromatography in the continuous manufacturing of monoclonal antibodies. The strategy utilizes a BioSMB system with a customized Python control layer and leverages the BioSMB valve manifold for in-line conditioning. Real-time monitoring of pH and conductivity, along with control of pumps and valves, allows for automated in-line conditioning inside the BioSMB manifold. The strategy eliminates the need for multiple BioSMB units or external equipment, offering a simple and robust structure for integrating multiple polishing chromatography steps.

Summary: In this study, the activity of L-asparaginase II (MW 135 kDa) from E. coli was observed using NMR technology. It was found that a flexible loop structure of the enzyme played a key role in its activity. Combining isothermal titration calorimetry (ITC) and NMR, it was demonstrated that changes in protein conformation could result in loss of function. The results indicate that 2D NMR can be reliably used to evaluate the structure-function relationship of this enzyme without the need for protein labeling.
