10-Phenyl-10H-phenoxazine-4,6-diol tetrahydrofuran monosolvate

open access: yesIUCrData, 2020
In the crystalline state of the title solvate, C18H13NO3·C4H8O, hydrogen-bonding interactions between hydroxyl groups on a phenoxazine backbone and the tetrahydrofuran solvent are observed that suggest the ability for this compound to act as a chelating ...

On Davidson’s Metaphor Theory

open access: yesFelsefe Arkivi, 2022
Davidson placed his critical approach mostly opposite the semantic theories of metaphor. Accordingly, metaphors – as the opposite of these theories – should to be assumed as having only one meaning. Davidson distinguished statements as matters of meaning

Is Jacobi--Davidson Faster than Davidson?

open access: yesSIAM Journal on Matrix Analysis and Applications, 2004
A new convergence analysis of Davidson's method for computing the smallest eigenvalue of a large symmetric matrix \(A\) is given. One of the main results provides a quantitative convergence bound, which proves that the eventual convergence rate is not larger than \(1/9\), provided that \(A\) has distinct eigenvalues and is sufficiently close to being ...

Las Neurociencias en el 150 aniversario de Freud. La apuesta psicoanalítica por el sujeto hoy... como ayer

open access: yesArbor: Ciencia, Pensamiento y Cultura, 2007
Suponer que el avance de las neurociencias puede llegar a inhabilitar las explicaciones psicoanalíticas; pensar que las explicaciones psicoanalíticas son potencialmente reductibles a explicaciones fisioneuronales y/o pensar que las neurociencias pueden ...
