Application of Mudline Tubing Hanger in Dry Tree Well on TLP Platform
Shiyou jixie, 2018 Reducing the tension of the TTR riser of the TLP platform could help to reduce the platform load and size. The overall and local tension force analyses of the TTR system indicate that the gravity of the TTR riser does not affect the top tension of the ...

Advanced Robotics Research, EarlyView.Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...

Advanced Science, EarlyView.This study demonstrates that HDAC1/2 knockout in microglia alleviates neurological deficits, preserves white matter, and accelerates hematoma clearance after ICH. HDAC1/2 inhibition reduces HK2 acetylation, shifts metabolism from glycolysis to fatty acid oxidation, reduces inflammation, and enhances phagocytosis.
