Synthesizing bijective lenses [PDF]

open access: yesProceedings of the ACM on Programming Languages, 2017
Bidirectional transformations between different data representations occur frequently in modern software systems. They appear as serializers and deserializers, as parsers and pretty printers, as database views and view updaters, and as a multitude of different kinds of ad hoc data converters. Manually building bidirectional transformations---by writing

Glyceryl-Ether Monooxygenase [EC 1.14.16.5J Part VIII. Probing the Nature of the Active Site

open access: yesPteridines, 1995
The V /K kinetic parameters for glyceryl-ether monooxygenase with 3-1 '-n-alkoxypropane-I,2-diols having alkyl sidechains varying from Cll to C22 (lb-k, 2a and b, and 3d) were determined. Maximum activity was found with the CI6 ethers, dropping almost to

Synthesizing symmetric lenses [PDF]

open access: yesProceedings of the ACM on Programming Languages, 2019
Lenses are programs that can be run both "front to back" and "back to front," allowing updates to either their source or their target data to be transferred in both directions. Since their introduction by Foster et al., lenses have been extensively studied, extended, and applied.

The Syntheses of Glycosylbarbiturate.

open access: yesChemical and Pharmaceutical Bulletin, 1964
By condensation of 1-(2, 3, 4, 6-tetra-O-acetyl-β-D-glucopyranosyl) urea (IV) with malonyl chloride in pyridine, N, N'-bis (2, 3, 4, 6-tetra-O-acetyl-β-D-glucopyranosylcarbamoyl)-malondiamide (V) was obtained. This compound, when treated with alkali, afforded each one mole of 1-(β-D-glucopyranosyl) urea and sodium 1-(β-D-glucopyranosyl) barbiturate (VI)
