Research on the Behavior of Coiled Tubing Running Based on Experiment

Shiyou jixie, 2018
The coiled tubing is subject to complex forces in downhole condition. The loads like gravity, liquid resistance, bending moment and torque, and environmental factors such as temperature and pressure make the coiled tubing prone to buckling during running.

The Use of Coiled Tubing as a Velosity String

Acta Montanistica Slovaca, 2004
Liquid loading is a problem in many gas wells especially older and depleted type reservoirs. If steps are not taken to minimize this effect, it will severely limit the production or even "kill" the well. This is the result of insufficient transport energy in the gas phase to carry the liquid that will accumulate around the well bore.

Human‐Scale Rotating Magnetic Field Delivery With Permanent Magnets Under Anatomic and Robotic Constraints

Advanced Robotics Research, EarlyView.
Rotating magnetic fields (RMFs) are widely used for microrobot propulsion and control. We show that RMF generation with permanent magnets is mechanically feasible for many limb and intracranial applications but becomes constrained for thoracic targets.

PRMT1‐Mediated LDHA Methylation Drives STAT3 Lactylation to Orchestrate Intestinal Inflammation and Tumorigenesis

Advanced Science, EarlyView.
This study identifies an immunometabolic axis wherein SAM‐driven PRMT1 methylates LDHA, enhancing its activity. The resultant lactate induces STAT3 K709 lactylation, which stabilizes an active conformation to promote STAT3 phosphorylation and IL‐10 expression.

AI‐Designed Cyclic Peptides Enable Controllable Modulation of the CD28 Immune Checkpoint

Advanced Science, EarlyView.
AI‐designed cyclic peptides enable controllable modulation of the CD28 immune checkpoint through reversible disruption of CD28‐CD80/CD86 interactions. The lead peptide, CIP‐3, suppresses T‐cell activation without intrinsic agonist activity, demonstrates dose‐dependent efficacy in a murine colitis model, and attenuates inflammatory cytokine production ...
