Understanding and using the meaning of statements in a bio- ontology: recasting the Gene Ontology in OWL
(Springer Nature, 2007-02-20)
The bio-ontology community falls into two camps: first we have biology domain experts, who actually hold the knowledge we wish to capture in ontologies; second, we have ontology specialists, who hold knowledge about ...
Structural effects of oxidation on sugars: glucose as a precursor of gluconolactone and glucuronolactone
(RSC, 2024-05)
Although structural information on sugars is wide, experimental studies on the oxidation products of sugars in the gas phase, free from solvent interactions, have been rarely reported. We present an experimental work on ...
