Abstract: Provided here are adsorbent compositions containing polyvinyl alcohol-bonded pellets of zeolite templated carbon. Also provided here are methods of producing adsorbent compositions by forming an aqueous mixture containing a binder, water, and zeolite-templated carbon; subjecting the aqueous mixture to a drying process to remove the water and form a dry mixture of the binder and the zeolite-templated carbon, and compacting the dry mixture of the binder and the zeolite-templated carbon to form the binder-bonded pellets of the zeolite templated carbon.

Abstract: Disclosed are an optical-time-division-multiplexed transmission method and system using a simple sinusoidally modulated optical signal as an input pulse source. An optical-time-division-multiplexed transmission system comprises: an optical-time-division-multiplexed transmitter by applying a sinusoidal electrical signal, a first multi-level electrical PAM signal, and a second multi-level electrical PAM signal so as to generate an optical-time-division-multiplexed multi-level PAM signal; an optical detector for converting the transmitted optical-time-division-multiplexed PAM signal into an electrical signal; a time-division-demultiplexer for demultiplexing the detected electrical signal into two signals; a MIMO equalizer; and two decision elements for determining the levels of two demultiplexed signals obtained from the MIMO equalizer.

Abstract: Disclosed are three-dimensional image registration via dense staining and a super-resolution multiplexed imaging method using the same. The three-dimensional image registration includes: placing at least one fiducial marker in an internal structure of a living tissue via dense staining; obtaining a plurality of images by repeatedly imaging the living tissue while replacing a fluorescent label attached to at least one target molecule within the living tissue where the fiducial marker is placed; and registering the images using the fiducial marker as a reference to obtain a final image of the target molecule.

Abstract: The present invention relates to a pharmaceutical composition for preventing or treating coronavirus disease 2019, and more specifically to a pharmaceutical composition for preventing or treating coronavirus disease 2019 found by drug repositioning technology using drug virtual screening technology. The pharmaceutical composition for preventing or treating coronavirus disease 2019 according to the present invention is a composition obtained by finding new uses for drugs, which have already been proven effective, for preventing or treating coronavirus disease 2019 by drug repositioning technology. The pharmaceutical composition is useful because it has significantly lower side effects than new drugs and can be rapidly applied to clinical practice.
