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 $U_{e3} = 0$.

A relaxed block splitting preconditioner for complex symmetric indefinite linear systems
Open Mathematics, 2018 In this paper, we propose a relaxed block splitting preconditioner for a class of complex symmetric indefinite linear systems to accelerate the convergence rate of the Krylov subspace iteration method and the relaxed preconditioner is much closer to the ...

Quasilocality of joining/splitting strings from coherent states
, 2007 Using the coherent state formalism we calculate matrix elements of the one-loop non-planar dilatation operator of ${\cal N}=4$ SYM between operators dual to folded Frolov-Tseytlin strings and observe a curious scaling behavior.

A lattice determination of Sigma - Lambda mixing [PDF]
, 2014 Isospin breaking effects in baryon octet (and decuplet) masses are due to a combination of up and down quark mass differences and electromagnetic effects and lead to small mass splittings.

Structural conserved moiety splitting of a stoichiometric matrix
Journal of Theoretical Biology, 2020 Characterising biochemical reaction network structure in mathematical terms enables the inference of functional biochemical consequences from network structure with existing mathematical techniques and spurs the development of new mathematics that exploits the peculiarities of biochemical network structure. The structure of a biochemical network may be

On properties of some matrix splittings
The Electronic Journal of Linear Algebra, 2001 In iterative methods for linear systems, a matrix is split as \(A=M-N\) and the iteration is \(x^{(t+1)}=M^{-1}Nx^{(t)}+M^{-1}b\), \(t\geq 0\). The splitting is called convergent if the iterative method converges, i.e., if \(\rho(M^{-1}N)

Study on the flexure performance of fine concrete sheets reinforced with textile and short fiber composites [PDF]
MATEC Web of Conferences, 2019 In order to study the influences of the contents of short fiber on the mechanical properties of concrete matrix, the properties of compressive, flexure and splitting of concrete matrix reinforced by alkali resistant glass fiber and calcium carbonate ...
