The research focuses on software packages at the application library level by aggregating data from over half a million observations of FOSS libraries used in production applications at thousands of companies in 2020. “FOSS has become a critical part of the modern economy. There are tens of ...
In the meantime, we performed DDA analysis of fractionated mouse membrane proteome and yeast proteome samples on QE HF and timsTOF Pro instruments. The DDA data was used to build project-specific libraries typically required for DIA data mining (Fig. 1a). Fig. 1: Schematic of the benchmarking...

We provide a photocatalytic radical cascade to create libraries of chiral tetrahydrocarbolinones under benign circumstances, with high regio-, -stereo, and chemoselectivity. This radical cascade may produce two of the three monoterpenoid indole-alkaloid, including the aspidosperma-type and corynanthe-...
Simple/limited/incomplete benchmark for scalability, speed and accuracy of machine learning libraries for classification All benchmarks are wrong, but some are useful This project aims at a minimal benchmark for scalability, speed and accuracy of commonly used implementations of a few machine learning...
