USF binding sequences from the HS4 insulator element impose early replication timing on a vertebrate replicator [PDF]

, 2012
The nuclear genomes of vertebrates show a highly organized program of DNA replication where GC-rich isochores are replicated early in S-phase, while AT-rich isochores are late replicating.

Comprehensive simulation of snow crystal deposition and electric field characteristics of composite sheath improved porcelain cantilever insulator in a wind and snow environment

Journal of Measurement Science and Instrumentation, 2022
The installed porcelain insulators on existing railway lines in China are prone to "snow flash" in winter. In order to prevent the occurrence of "snow flash" and improve the reliability of the insulators, a composite-porcelain insulator is designed.
