Abstract: The present invention relates to application of gossypol and its optical isomers to preparation of an anti-Coronavirus drug. Specifically disclosed is application of pharmaceutically acceptable salts, solvates, isotopes, stereoisomers, stereoisomer mixtures, and tautomers of the gossypol and its optical isomers to preparation of a drug for preventing and/or treating a disease caused by a Coronavirus. The Coronavirus is MERS-CoV, SARS-CoV, or SARS-CoV-2. It is found in the present invention for the first time that the gossypol and its optical isomers can inhibit the activity of Coronavirus 3CL proteases to achieve an anti-Coronavirus effect. The half maximal inhibitory concentrations of gossypol and (?)-gossypol to SARS-CoV proteases and SARS-CoV-2 3CL proteases are all lower than 10 ?M. The anti-Coronavirus 3CL protease effect is good. Therefore, the gossypol and its optical isomers have the potential for use in the preparation of a drug for preventing and/or treating novel Coronavirus infections.

Abstract: Methods, apparatuses and systems for providing dehumidification providing dehumidification for gas detecting components are disclosed herein. An example apparatus may comprise: a humidity sensing component configured to generate a humidity level indication associated with gaseous substance in a gas flow channel, a dehumidifier component disposed along the gas flow channel, a gas detecting component disposed downstream with respect to the dehumidifier component along the gas flow channel, and a controller component in electronic communication with the humidity sensing component and the dehumidifier component.

Abstract: An apparatus is programmed with a plurality of programming instructions for automatically generating a reconfiguration script comprising a plurality of configuration commands for reconfiguring a plurality of telecommunication devices of a telecommunication system, based on a current and a target descriptive image of the telecommunication system. The current descriptive image specifies the devices and their features included in the current configuration of the telecommunication system, whereas the target image specifies the devices and their features to be included in the target configuration of the telecommunication system. The plurality of programming instructions generate the reconfiguration script employing feature dependency graph (FDG) data structures, a device model modeling the rules and behaviors of the telecommunication devices, and feature deletion/addition linklists.
