Rethinking Grant-Free Protocol in mMTC

GLOBECOM 2024 - 2024 IEEE Global Communications Conference
This paper revisits the identity detection problem under the current grant-free protocol in massive machine-type communications (mMTC) by asking the following question: for stable identity detection performance, is it enough to permit active devices to transmit preambles without any handshaking with the base station (BS)?

Biosynthese des vollständig gesättigten C16‐Homosesquiterpens Descartan durch Deprotonierung mit Cyclopropanierung

Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.
Eine nicht‐kanonische C16‐Sesquiterpensynthase aus Morganella morganii produziert das ungewöhnliche Grundgerüst Descartan. Ihr Cyclisierungsmechanismus wurde mittels Isotopenmarkierungsexperimenten und DFT‐Berechnungen aufgeklärt. Gezielte Mutagenese veränderte die Enzymfunktion und führte zu alternativen Produkten, darunter Voltairen, dessen ...
