Merging the Spectral Theories of Distance Estrada and Distance Signless Laplacian Estrada Indices of Graphs [PDF]
Suppose that G is a simple undirected connected graph. Denote by D(G) the distance matrix of G and by Tr(G) the diagonal matrix of the vertex transmissions in G, and let α∈[0,1] . The generalized distance matrix Dα(G) is defined as Dα(G)=αTr(G)+(1−α)D(G)

Generalized Hermite processes, discrete chaos and limit theorems [PDF]
We introduce a broad class of self-similar processes $\{Z(t),t\ge 0\}$ called generalized Hermite process. They have stationary increments, are defined on a Wiener chaos with Hurst index $H\in (1/2,1)$, and include Hermite processes as a special case ...

CMB Polarization Data and Galactic Foregrounds: Estimation of Cosmological Parameters [PDF]
We estimate the accuracy with which various cosmological parameters can be determined from the CMB temperature and polarization data when various galactic unpolarized and polarized foregrounds are included and marginalized using the multi-frequency ...

Correlated noise in networks of gravitational-wave detectors: subtraction and mitigation [PDF]
One of the key science goals of advanced gravitational-wave detectors is to observe a stochastic gravitational-wave background. However, recent work demonstrates that correlated magnetic fields from Schumann resonances can produce correlated strain noise

The Hyper-Wiener Index of Trees of Order n with Diameter d
The hyper-Wiener index is a kind of extension of the Wiener index, used for predicting physicochemical properties of organic compounds. The hyper-Wiener index WW(G) is defined as WW(G)=1/2∑u,v∈VGdGu,v+dG2u,v with the summation going over all pairs of ...

Hosoya Polynomial, Wiener Index, Coloring and Planar of Annihilator Graph of Zn [PDF]
Let R be a commutative ring with identity. We consider ΓB(R) an annihilator graph of the commutative ring R. In this paper, we find Hosoya polynomial, Wiener index, Coloring, and Planar annihilator graph of Zn denote ΓB(Zn) , with n= pm or n=pmq, where p,
