Modeling and Simulation of Bottom Hole Pattern of Hybrid Bit and Cutter Layout Optimization
Shiyou jixie, 2020 The outline of the cutting structure of the hybrid bit is the projection of the cone cutting structure and the PDC cutting structure on the same two-dimensional plane, which will lose part of the cutter distribution information and will limit the design ...

Deep neural networks to correct sub-precision errors in CFD
Applications in Energy and Combustion Science, 2022 Information loss in numerical physics simulations can arise from various sources when solving discretised partial differential equations. In particular, errors related to numerical precision (“sub-precision errors”) can accumulate in the quantities of ...

FEBS Letters, EarlyView.Cancer progression is regulated by the dynamic matrix code of the tumor microenvironment, which influences cellular behavior and disease development. Importantly, matrix remodeling in three‐dimensional cancer models more accurately reflects in vivo conditions compared to conventional two‐dimensional systems.
