1/N ExpansionAmong the possible CP-odd couplings of the axion to ordinary matter, the most relevant ones for phenomenology are the Yukawa couplings to nucleons. We analyze such non-derivative couplings within three different approaches: standard effective field theory, the Skyrme model and ...

Ellipticine is a natural alkaloid isolated from the leaves of Ochrosia elliptica; it has a 6H-pyrido[4,3-b]carbazole scaffold (Fig. 5.1) [3–5]. It intercalates between adjacent base pairs and changes their orientation to interact with single-stranded nucleic acids formed locally during D...
The tetracyclines are a family of polyketide natural products or their semisynthetic derivatives based upon the naphthacene tetracycline ring system which have been used widely for over 50 years in human healthcare, veterinary medicine, and agriculture. ...
