Compatibility and Accuracy Verification of CADmesh-Based Complex Geometry Modeling in Geant4
Shiwei Jing, Weiyang Zhang, Shengduo Liu +11
Geant4 Monte Carlo simulation relies on the Constructive Solid Geometry (CSG) method for complex geometric modeling. This method has low efficiency and a high application threshold…
A Method for Neutron-Gamma Pulse Shape Discrimination of CLYC Detector Based on a Gated Residual-Linear Attention Network
Shiwei Jing, Shengduo Liu, Weiyang Zhang +11
The discrimination of neutron and gamma pulse shapes is a key technology in fields such as nuclear safety monitoring and radiation assessment. An enhanced recursive gated cyclic re…
Optimized design of a Penning ion source for sealed neutron tube
Shiwei Jing, Jia Song, Shengduo Liu +7
Sealed neutron tubes have a wide range of applications, and the ion source is their core component. Penning ion sources commonly suffer from issues such as uneven magnetic field di…
Learning a potential formulation for rate-and-state friction
Shengduo Liu, Kaushik Bhattacharya, Nadia Lapusta
Empirical rate-and-state friction laws are widely used in geophysics and engineering to simulate interface slip. They postulate that the friction coefficient depends on the local s…
