Chaos in Si MMIC Oscillators [PDF]
This paper analyzes the dynamics of two Si circuits in miliimetric band for which chaotic responses had been experimentally observed. The aim has been to determine, in each case, the particular phenomena leading to the chaotic response, in order to avoid this behavior in future realizations of these circuits.

Lichen and Its Microbiome as an Untapped Source of Anti‐Biofilm Compounds
Lichens and their associated fungi give rise to the evaluation of several extracts and compounds against biofilms. ABSTRACT Lichen substances have been first described in the 1870s, and around 10 000 compounds have been isolated and characterized. Most of them have been evaluated for their activity on planktonic microorganisms (bacteria and fungi ...
