Abstract: A synthesis method of a targeted drug nCoVshRNA.2ACE2 of a COVID-19 virus, which includes the following steps: designing a consensus RNAi sequence siRNA of the COVID-19 virus and a variant strain thereof; synthesizing two complementary siRNAs into a small hairpin-shaped shRNA with a loop, and synthesizing ACE2 or a cell penetrating peptide ACE2 with a receptor-binding domain (RBD) as a ligand; and ligating the ACE2 to a sense strand and an antisense strand of the shRNA separately to synthesize the nCoVshRNA.2ACE2 including a shRNA region and an ACE2 region. The bivalent ACE2 functions to neutralize the RBD and deliver the shRNA in a targeted manner; an “shRNA-ACE2-RBD-virus” complex bridged by the ACE2 allows the shRNA to enter target cells with virus infection, thereby avoiding a side effect of non-specific delivery of the shRNA to uninfected cells, as well as resisting the variant strain and neutralizing the virus with the ACE2.

Abstract: A method, computer program product, and computer system for processing instances of message sequences. Two or more instances are received. Each instance has an instance number and an associated instance Id. Each instance includes a stream of one or more messages. Each message in each stream is associated with a respective task. All messages in the two or more instances whose respective tasks have been completed are distributed into partitions in the broker. Different messages in each instance of at least one instance are distributed into different partitions. The messages distributed in the partitions include parallel task messages. The parallel task messages are sequenced by being grouped by the instance number or instance Id and are sequentially ordered in each group in an ascending order of a timestamp of arrival of each parallel task message at the broker. The parallel task messages in each instance are dispatched to a service.

Abstract: A method for correcting infant crying identification includes the following steps: a detecting step provides an audio unit to detect a sound around an infant to generate a plurality of audio samples. A converting step provides a processing unit to convert the audio samples to generate a plurality of audio spectrograms. An extracting step provides a common model to extract the audio spectrograms to generate a plurality of infant crying features. An incremental training step provides an incremental model to train the infant crying features to generate an identification result.
