A datamining approach to predict the formation enthalpy for rareearth dihydrides REH2 (RE = Ce,Pr,Dy)
(Elsevier Ltd, 2016)Different theoretical methods estimating the formation enthalpy for hydrides have been adopted, among them the density functional theory (DFT) calculations. In this paper, an attempt has been made to study and estimate the ... 
A Double Parton Scattering Background to Associate WH and ZH Production at the LHC
(2007)Higgs boson production in association with W and Z bosons at high luminosity CERN Large Hadron Collider (LHC, sqrt(s) = 14 TeV), is one of the most promising discovery channel for a SM Higgs particle with a mass below 135 ... 
A facile method for the fabrication of hierarchical porous nanocrystalline zeolite silicalite1
(2011)Zeolites are used in several industrial applications as catalysts, ionexchangers and molecular sieves. The superior performance is related to the presence of welldefined micropores in the zeolite structure. However, in ... 
A Family of Second Order Methods for Variable Coefficient Fourth Order Parabolic Partial Differential Equations
(1987)A family of second order methods is developed for the numerical solution of variable coefficient fourth order parabolic partial differential equations in one space variable. The methods arise from a three point recurrence ...
