Influence of resonances in hyperonic neutron stars on gravitational-wave inspiral signatures
Athira S., Vivek Baruah Thapa, Monika Sinha
The composition of dense matter in neutron star interiors remains uncertain, with the possible appearance of the non-strange resonances providing an important source of theoret…
CoPiT: A conditional Position-induced Transformer for aerodynamic field prediction on unstructured meshes
Junfeng Chen, Yongchen Fan, Zhonghua Qiao +1
High-fidelity Reynolds-averaged Navier--Stokes (RANS) simulations remain a standard tool for aerodynamic analysis, yet each solve on an unstructured mesh is computationally expensi…
An efficient and stable diffusion generated method for quadrilateral mesh generation in general domains
Jingwen Dai, Zhonghua Qiao, Dong Wang
This paper introduces a novel, robust, and computationally efficient framework for high-quality quadrilateral mesh generation on general two-dimensional domains. The core of the pr…
A new randomized CholeskyQR based on LU decomposition with partial pivoting
Yuwei Fan, Haoran Guan, Zhonghua Qiao
CholeskyQR has received considerable attention in recent years for its efficiency and simplicity in computing QR decomposition of the tall-skinny wit…
An improved Shifted CholeskyQR based on columns
Yuwei Fan, Haoran Guan, Zhonghua Qiao
Among all the deterministic CholeskyQR-type algorithms, Shifted CholeskyQR3 is specifically designed to address the QR factorization of ill-conditioned matrices. This algorithm int…
