A neutrino mass matrix with seesaw mechanism and two-loop mass splitting [PDF]

, 2000
We propose a model which uses the seesaw mechanism and the lepton number $\bar L = L_e - L_\mu - L_\tau$ to achieve the neutrino mass spectrum $m_1 = m_2$ and $m_3 = 0$, together with a lepton mixing matrix $U$ with $U_{e3} = 0$.

Magnetic Photon Splitting: Computations of Proper-time Rates and Spectra [PDF]

, 1997
The splitting of photons in the presence of an intense magnetic field has recently found astrophysical applications in polar cap models of gamma-ray pulsars and in magnetar scenarios for soft gamma repeaters.

A Data-Driven Parameter Prediction Method for HSS-Type Methods

Mathematics, 2022
Some matrix-splitting iterative methods for solving systems of linear equations contain parameters that need to be specified in advance, and the choice of these parameters directly affects the efficiency of the corresponding iterative methods. This paper

Albertson (Alb) spectral radii and Albertson (Alb) energies of graph operation

Frontiers in Chemistry, 2023
The sum of the absolute eigenvalues of the adjacency matrix make up graph energy. The greatest absolute eigenvalue of the adjacency matrix is represented by the spectral radius of the graph.
