Ready‐made chromatography columns for extracellular vesicle isolation from plasma

open access: yesJournal of Extracellular Vesicles, 2015
Proteomic studies of circulating vesicles are hampered by difficulties in purifying vesicles from plasma and serum. Isolations are contaminated with high-abundance blood proteins that may mask genuine vesicular-associated proteins and/or simply provide ...

Automata column

ACM SIGLOG News, 2014
In this column, Sylvain Schmitz summarizes two recent advances on the complexity of the reachability problem for vector addition systems with states. This is one of the most celebrated decidable problems in theoretical computer science, and until now, there was absolutely no upper bound on the complexity.

Complexity Column

ACM SIGLOG News, 2022
Descriptive complexity theory initiated by celebrated Fagin's theorem aims to characterize complexity classes by the kind of logic necessary to express problems in the class. For many complexity classes such a characterization has been found; this includes the class NP that, according to Fagin's theorem, can be characterized by the monadic second order
