Synthesis mechanism of superheavy element 120: a dinuclear system model approach with microscopic inputs
Wei Zhang, Shi-Jie Zhang, Peng-Hui Chen
The dinuclear system model incorporates several essential input physical quantities, including nuclear mass, fission barrier, shell correction energy, level density parameter, and…
Sequential subspace methods on Stiefel manifold optimization
Pengwen Chen, Chung-Kuan Cheng, Chester Holtz
We investigate the minimization of a quadratic function over Stiefel manifolds (the set of all orthogonal - frames in ), which has applications in high-dimensional…
Semi-Supervised Laplace Learning on Stiefel Manifolds
Chester Holtz, Pengwen Chen, Alexander Cloninger +2
Motivated by the need to address the degeneracy of canonical Laplace learning algorithms in low label rates, we propose to reformulate graph-based semi-supervised learning as a non…
Local saddle structure in relaxed averaged alternating reflections Algorithms on phase retrieval
Pengwen Chen
Phase retrieval can be expressed as one non-convex constrained optimization problem to identify one phase minimizer in the primal space. Many iterative transform techniques have be…
Arnoldi algorithms with structured orthogonalization
Pengwen Chen, Chung-Kuan Cheng, Xinyuan Wang
We study a stability preserved Arnoldi algorithm for matrix exponential in the time domain simulation of large-scale power delivery networks (PDN), which are formulated as semi-exp…
Blind Ptychography: Uniqueness and Ambiguities
A. Fannjiang, P. Chen
Ptychography with an unknown mask and object is analyzed for general ptychographic measurement schemes that are strongly connected and possess an anchor. Under a mild constraint on…
