Abstract Data-driven AI (artificial intelligence) models have become instrumental in drilling operations, offering potential efficiency gains through real-time predictions and decision support. However, while access to diverse datasets from different fields companies can significantly enhance model performance, data sharing is often constrained by strict security privacy regulations. To overcome these challenges, we developed a federated learning framework that enables collaborative training...

Retinoic acid receptor alpha (RARα) plays an essential role in the regulation of many biological processes, such as hematopoietic cell differentiation, while abnormal RARα function contributes to pathogenesis certain diseases including cancers, especially acute promyelocytic leukemia (APL). Recently, oridonin, a natural diterpenoid isolated from Rabdosia rubescens, was demonstrated regulate by increasing its protein level. However, underlying molecular mechanism for this action has not been...

Chlorophylls are the major pigments present in photosynthetic plants but their application foods is limited due to lack of solubility aqueous media and susceptibility degradation during processing storage. These problems might be overcome by addition sodium caseinate (NaCas) whose hydrophobic hydrophilic groups may result electrostatic steric stabilization. In work, 1% 3% (w/w) chlorophylls NaCas dispersion or ethanol (control) were prepared color stability under light treatment for 5 h...

The standard penetration test (SPT) is a widely used in situ method worldwide that can evaluate soil properties based on the blow counts (N-value). N-value depends properties, and energy transferred to drill pipe during hammering. Currently, European American scholars generally believe variation amount of hammer transmitted due different types drop systems primary factor leads variations N-value. In China, there lack research quantitative transfer efficiency system data from instrument. this...

Permanent downhole gauges (PDG) are massively installed in injection and production wells operated different industries such as oil gas, geological CO2 storage, the geothermal industry. These provide a vast amount of real-time pressure measurements. The measurements may be divided into periods with predominantly monotonic change response to sudden rate, called transients. transients caused by well operations, variation or rate shut-ins. Transient identification is one important steps...
