Phylogenetic Stochastic Mapping without Matrix Exponentiation [PDF]
Journal of Computational Biology, 2014 Phylogenetic stochastic mapping is a method for reconstructing the history of trait changes on a phylogenetic tree relating species/organisms carrying the trait. State-of-the-art methods assume that the trait evolves according to a continuous-time Markov

Jarlskog Invariant of the Neutrino Mapping Matrix [PDF]
Annals of Physics, 2007 The Jarlskog Invariant $J_{\nu-map}$ of the neutrino mapping matrix is calculated based on a phenomenological model which relates the smallness of light lepton masses $m_e$ and $m_1$ (of $\nu_1$) with the smallness of $T$ violation.

Applications of uniform boundedness principle to matrix transformations
Karpatsʹkì Matematičnì Publìkacìï, 2023 Using the uniform boundedness principle of Maddox, we characterize matrix transformations from the space $(\ell_{p}) _{T}$ to the spaces $m(\phi )$ and $n(\phi )$ for the case $1\leq p\leq \infty$, which correspond to bounded linear operators.

On the fine spectra of the generalized difference operator $\Delta_{uv}$ over the sequence space $c_0$ [PDF]
Journal of Mahani Mathematical Research, 2012 The main purpose of this paper is to detemine the fine spectrum of the generalized difference operator $\Delta_{uv}$ over the sequence space c0. These results are more general than the fine spectrum of the generalized difference operator $\Delta_{uv}$ of

Reliable Virtual Network Mapping Algorithm With Network Characteristics and Associations
IEEE Access, 2021 In the existing research on reliable virtual network mapping, the relationship between network parameters is insufficiently analyzed, the network topology and historical mapping data are not fully utilized, resulting in a low virtual network mapping ...

Design of a Physical Layer Encryption Scheme for Rate Compatible Modulation
IEEE Access, 2020 Spectral efficiency and transmission security are both essential metrics for wireless communication. Rate compatible modulation (RCM) is an adaptive transmission scheme to improve the spectral efficiency. However, the mapping matrix of RCM is fixed. Once

Indecomposable Positive Maps in Matrix Algebras [PDF]
Canadian Mathematical Bulletin, 1988 AbstractWe prove that Choi's map in M3 cannot be written as the sum of a 2-positive map and a 2-copositive map. We also provide other examples of positive maps in Mn which cannot be written as the sum of an n-positive map and a 2-copositive map.
