Abstract: A process for producing a barrier composition includes subjecting a siloxane compound having 1 to 3 amino groups and an aqueous solution including water and an alcohol to hydrolysis and first-stage condensation under required conditions, subjecting a first colloidal mixture obtained and an additional alcohol to second-stage condensation, subjecting a second colloidal mixture obtained, which has a particular solid content, to heating under required conditions, and subjecting a cured product obtained to aging under required conditions. A barrier composition produced by the process is also disclosed.

Abstract: A data processing system can be operated in one of a preprocessing mode, a short-read mapping mode, a sequence assembly mode or a variant calling mode that are related to a to-be-tested DNA sequence. The data processing system includes a sorting engine that supports high-speed processing of sorting in the preprocessing mode and the sequence assembly mode, and a dynamic processing engine that supports dynamic programming calculations in the short-read mapping mode and the variant calling mode. The data processing system may be implemented on a system-on-chip (SoC) for performing accelerated processing of gene sequencing data with reduced memory requirements.
