Drill string dynamic characteristics simulation for the ultra-deep well drilling on the south margins of Junggar Basin

Petroleum, 2023
Improper drilling parameters may cause severe vibration of drill string which leads to reduce the rate of penetration and drilling tool premature failure accidents in the drilling process of ultra-deep well.

Sandwich‐Structured Aramid Composite Papers with Heterogeneous Dielectric Layers for Integrated Corona Resistance and Thermal Conductivity

Advanced Science, EarlyView.
A sandwich‐structured aramid composite paper was designed to integrate high corona resistance and thermal conductivity. The fluorinated graphene/aramid surface layers effectively dissipate space charges to suppress corona discharge. Meanwhile, the boron nitride nanotube/aramid core layer constructs continuous heat‐conduction pathways.

Drill String Drag and Torque Test Device Design

Shiyou jixie, 2019
The existing drag and torque theoretical model has many assumptions, leading to a large difference between the calculated value and the true value, which seriously restricts the study of the mechanical behavior of the drill string and the optimization of

A Generalizable Framework for Building Executable Domain‐Specific Large Language Models Under Data Scarcity: Demonstration on Semiconductor Technology Computer‐Aided Design Simulation

Advanced Intelligent Systems, EarlyView.
A schema‐first alignment framework builds compact, executable domain‐specific language models under data scarcity. Large‐scale synthetic question‐answer generation instills domain knowledge, and a code‐centric IR‐to‐DPO pipeline aligns generation with tool‐executable syntax.

Arthroscopic Dynamic Anterior Stabilization and Augmentation of Bony Bankart Lesions With Transfer of the Long Head of the Biceps

Arthroscopy Techniques, EarlyView.
Abstract Bony Bankart fractures treated arthroscopically with conventional suture anchor fixation are often complicated by fragment displacement and nonunion because of inadequate reduction. This technical report introduces a novel technique using the long head of the biceps (LHB) tendon transfer for elevating bony fragment and augmenting suture anchor

Bricks, knots, and bodies: Material encounters and the affective making of masculinity

British Educational Research Journal, EarlyView.
Abstract This paper examines how creative research methods do not just capture boys' experiences of masculinity, but actively materialise them. Drawing on two arts‐based activities used in school‐based fieldwork (a mannequin‐based exercise with one participant and a Lego‐building workshop with a small peer group), the paper analyses how materials ...
