Data integration across conditions improves turnover number estimates and metabolic predictions

open access: yesNature Communications, 2023
The construction of protein-constrained genome-scale metabolic models depends on the integration of organism-specific enzyme turnover numbers. Here, the authors show that correction of turnover numbers by simultaneous consideration of proteomics and ...

Solution of generalised type – 2 Fuzzy boundary value problem

open access: yesAlexandria Engineering Journal, 2021
In this article, we proposed a new representation of type-2 fuzzy numbers called generalized type-2 fuzzy numbers. Dirichlet, Neumann and Mixed kind of boundary value problem have been considered with the boundary condition as generalized type-2 fuzzy ...

Condition Numbers of the Nonlinear Matrix Equation Xp-A⁎eXA=I

open access: yesJournal of Function Spaces, 2018
We explore the condition numbers of the nonlinear matrix equation Xp-A⁎eXA=I. Explicit expressions for the normwise, mixed, and componentwise condition numbers are derived.

The processing of symbolic and nonsymbolic ratios in school-age children. [PDF]

open access: yesPLoS ONE, 2013
This study tested the processing of ratios of natural numbers in school-age children. Nine- and eleven-year-olds were presented collections made up of orange and grey dots (i.e., nonsymbolic format) and fractions (i.e., symbolic format).

Norms and inequalities for condition numbers [PDF]

open access: yesPacific Journal of Mathematics, 1965
Abstract : The condition number c sub phi of a nonsingular matrix A is defined by c sub phi (A) = phi (A) phi (A superscript -1) where ordinarily phi is a norm. It was shown by J. D. Riley that if A is positive definite, c sub phi (A + kI) = or 0 and phi squared (A) is the maximum eigenvalue of AA* or phi squared (A) = Tr AA*.

Counting algebraic numbers in short intervals with rational points

open access: yesЖурнал Белорусского государственного университета: Математика, информатика, 2019
In 2012 it was proved that real algebraic numbers follow a non­uniform but regular distribution, where the respective definitions go back to H. Weyl (1916) and A. Baker and W. Schmidt (1970).

Negative Subtraction Hybridization: An efficient method to isolate large numbers of condition-specific cDNAs

open access: yesBMC Genomics, 2004
Background The construction of cDNA libraries is a useful tool to understand gene expression in organisms under different conditions, but random sequencing of unbiased cDNA collections is laborious and can give rise to redundant EST collections. We aimed

Numerical Stability in Complex Summation

open access: yesپژوهش‌های ریاضی, 2021
The natural and practical condition numbers for summation of complex numbers are introduced. These numbers measure the effect of loss of significant digits on the round-off error when computing a sum in floating point arithmetic. The relationship between
