Assessing the estimation of nearly singular covariance matrices for modeling spatial variables
(Wiley, 2023)
© 2023, Institute of Mathematical Statistics. All rights reserved.Spatial analysis commonly relies on the estimation of a co-variance matrix associated with a random field. This estimation strongly impacts the prediction ...
Tuning the Fano factor of graphene via Fermi velocity modulation

Origin of Fueguian-Patagonians: An approach to population history and structure using R matrix and matrix permutation methods
(Wiley-liss, Div John Wiley & Sons Inc, 2002-12)
A complicated history of isolation between Fueguian and Patagonian groups (originated by the appearance of the Straits of Magellan) as much as differences in population structure and life strategies constitute important ...
Convergence and computational efficiency enhancements in the iterative solution of the G-particle-hole hypervirial equation
(John Wiley & Sons Inc, 2011-04)
The G-particle-hole hypervirial (GHV) equation has been recently reported (Valdemoro et al., Sixth International Congress of the International Society for Theoretical Chemical Physics Vancouver: Canada, 2008. Alcoba et ...
The r-matrix of the Alday-Arutyunov-Frolov model
(SPRINGERNEW YORK, 2012)
We investigate the classical integrability of the Alday-Arutyunov-Frolov model, and show that the Lax connection can be reduced to a simpler 2 x 2 representation. Based on this result, we calculate the algebra between the ...
