Abstract: There is provided a ?-peptido sugar-copolymer having the structure of formula (I) as defined herein, or a stereoisomer, a tautomer, an N-oxide, a hydrate, a solvate, or a salt thereof, or a mixture of the same. There is provided a process to make the ?-peptido sugar-copolymer as defined herein. There are further provided medical applications of the ?-peptido sugar-copolymer as defined herein. In a preferred embodiment, a block-like copolymer poly(amido-D-glucose)-block-poly-?-(L)-homolysine (PDGu-b-PBLK) synthesized via anionic ring-opening polymerization (ROP) demonstrates an antimicrobial efficacy, an enhanced selectivity towards different bacteria, biocompatibility vs. mammalian cells and spontaneous assembly.

Abstract: A high-speed signal driving device includes an assist driver, a delay adjuster, and a plurality of drivers. The assist driver receives a control signal and is coupled to a first output node and a second output node to output a first current to the first output node or the second output node. The delay adjuster receives the control signal to generate a plurality of delay signals. Each of the delay signals has a different delay time corresponding to the control signal. One of the drivers receives the control signal, and other drivers correspondingly receive the plurality of delay signals. The plurality of drivers are coupled to the first output node and the second output node via a first output end and a second output end.
