Maintenance and replacement of aging water pipes are critical for urban development.To this end, trenchless rehabilitation methods that do not require excavation offer an efficient replacement for aging water pipes.Thus, this study developed a trenchless method using die drawing, which continuously inserts polyethylene (PE) liners into the reach po
Mutational (genetic) robustness is phenotypic constancy in the face of mutational changes to the genome.Robustness is critical to the understanding of evolution because phenotypically expressed genetic variation is the fuel of natural selection.Nonetheless, the evidence for adaptive evolution of mutational robustness in biological populations is co
IPv6 is majicontrast red a next-generation IP protocol that replaces IPv4.It not only expands the number of network address resources but also solves the problem of multiple access devices connected to the Internet.While IPv6 has brought excellent convenience to the public, related security issues have gradually emerged, and an assessment of the se
