Abstract: A fuel supply circuit for an aeronautical cryogenic turbomachine including: at least one cryogenic reservoir containing a liquid fuel topped with a boil-off gas and including a high-pressure liquid pump to supply at least one main propulsion device of the turbomachine with liquid fuel, an auxiliary turbomachine including an electric generator, a gas compressor to supply the auxiliary turbomachine with gaseous fuel, and a buffer gas reservoir connecting the gas compressor to the cryogenic reservoir to reinject gas into the cryogenic reservoir in order to maintain the pressure in the cryogenic reservoir above a predefined value, the electric generator supplying the high-pressure liquid pump and the gas compressor.

Abstract: Described herein are binding proteins useful against ACE2-targeted viruses (e.g., SARS-CoV and SARS-CoV-2, etc.), and methods of using them. These binding proteins may include an extracellular portion of angiotensin-converting enzyme 2 (ACE2), excluding the collectrin domain, and a flexible polypeptide flexible linker coupling the ACE2 portion to a fragment crystallization (Fc) domain. These binding proteins dimerize, and the flexible linker may be chosen to be sufficiently long to permit concurrent interaction with multiple Spike (S) proteins on the ACE2-targeted virus.
