Use of Noncanonical Tyrosine Analogues to Probe Control of Radical Intermediates during Endoperoxide Installation by Verruculogen Synthase (FtmOx1).

Important bioactive natural products, including prostaglandin H and artemisinin, contain reactive endoperoxides. Known enzymatic pathways for endoperoxide installation require multiple hydrogen-atom transfers (HATs). For example, iron(II)- and 2-oxoglutarate-dependent verruculogen synthase (FtmOx1; EC 1.

Predictive Models for the Characterization of Internal Defects in Additive Materials from Active Thermography Sequences Supported by Machine Learning Methods.

The present article addresses a generation of predictive models that assesses the thickness and length of internal defects in additive manufacturing materials. These modes use data from the application of active transient thermography numerical simulation. In this manner, the raised procedure is an ad-hoc hybrid method that integrates finite element simulation and machine learning models using different predictive feature sets and characteristics (i.
