Accurate GW frontier orbital energies of 134 kilo molecules

open access: yesScientific Data, 2023
HOMO and LUMO energies are critical molecular properties that typically require high accuracy computations for practical applicability. Until now, a comprehensive dataset containing sufficiently accurate HOMO and LUMO energies has been unavailable.

Accurate and Efficient Computations of the Greeks for Options Near Expiry Using the Black-Scholes Equations

open access: yesDiscrete Dynamics in Nature and Society, 2016
We investigate the accurate computations for the Greeks using the numerical solutions of the Black-Scholes partial differential equation. In particular, we study the behaviors of the Greeks close to the maturity time and in the neighborhood around the ...

Accurate Computation of Covariance

open access: yesTeaching Statistics, 1991
SummaryUsing as a starting point pre‐existing remarks on the discrepancies arising in calculations of statistical quantities from certain formulae because of errors in the means, or the choice of the appropriate formula, the author proposes a scheme by which teachers and students can overcome these difficulties and achieve error‐free results.

Accurate and Interpretable Computational Modeling of Chemical Mutagenicity [PDF]

open access: yesJournal of Chemical Information and Modeling, 2008
We describe a method for modeling chemical mutagenicity in terms of simple rules based on molecular features. A classification model was built using a rule-based ensemble method called RuleFit, developed by Friedman and Popescu. We show how performance compares favorably against literature methods.

A new method for solving ill-conditioned linear systems [PDF]

open access: yesOpuscula Mathematica, 2013
An accurate numerical method is established for matrix inversion. It is shown theoretically that the scheme possesses the high order of convergence of seven. Subsequently, the method is taken into account for solving linear systems of equations.

Computing smooth surface contours with accurate topology [PDF]

open access: yesACM Transactions on Graphics, 2014
This article introduces a method for accurately computing the visible contours of a smooth 3D surface for stylization. This is a surprisingly difficult problem, and previous methods are prone to topological errors, such as gaps in the outline.
