Dimeric and monomeric conformation of SARS-CoV-2 main protease: New technical approaches based on IR radiation

open access: hybridSpectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy
The main proteases Mpro are a group of highly conserved cysteine hydrolases in β-coronaviruses. They have been demonstrated to play an unavoidable role in viral replication, and consequently they have been suggested as key targets for treating coronavirus-caused infectious diseases, mainly from the COVID-19 epidemic.

Uniqueness of Neumann-Tricomi problem in IR/sup 2/. Technical note BN-906. [Energy-integral method] [PDF]

open access: green, 1979
Using a variation of the energy-integral method sufficient conditions for the uniqueness of the solution of the Neumann-Tricomi boundary value problem are obtained. A uniqueness theorem is given for a general function. 11 references. (JFP)

Scaffolding for re-engineering with organizational and technical frameworks [at the IRS] [PDF]

open access: yesProceedings of 6th International Workshop on Computer-Aided Software Engineering, 2002
Three studies concerning software reengineering conducted by the US Internal Revenue Service (IRS) in 1991 and 1992 are described. The situation at the IRS-aging, piecemeal information technology systems maintained by a large staff-is familiar to many institutions.
