Abstract: A page status management method includes collecting statistics on N first memory access commands received in a first time window; determining reception interval information of the N first memory access commands, where the reception interval information indicates denseness of a stream of commands in the first time window; determining active standby time based on the reception interval information; and after a second memory access command accesses a target memory page, if no other memory access command accesses the target memory page within the active standby time, closing the target memory page, where the second memory access command is any memory access command received in a second time window, and the second time window is a time window after the first time window.

Abstract: The present invention provides a helicase BCH2X, comprising an amino acid sequence represented by any one of SEQ ID NOs: 1-3. The present invention also provides a complex structure comprising the helicase BCH2X and a binding moiety for binding polynucleotides. The present invention also provides a use of the helicase BCH2X or the complex structure comprising same in the control and characterization of polynucleotides and single-molecule nanopore sequencing.

Abstract: A lid for a beverage container includes: a cap main body that attaches to an upper aperture part of a beverage container main body; and a liquid stopping member that is installed on the cap main body in a detachable manner, the cap main body includes a liquid through-hole that is formed by notching a part of an outer periphery of the cap main body, the liquid stopping member engages along external surfaces of liquid through-hole walls that form the liquid through-hole in addition to engaging with an engagement groove that is formed on an external surface of the cap main body, and an airflow opening is formed in a back part of the liquid stopping member.
