Introduction of Nano-hole sequencing technology Nano hole sequencing Fourth generation Sequencing The nano-sequencing is coming.The technology of Nano-hole sequencing (also known as the fourth Generation sequencing technology) is a new generation of sequencing technology that has arisen in recent years. The current sequencing length can reach 150kb. This technology began in the 90 's, underwent three major technological innovations: one, single molecule DNA from the nano-hole

GE switches are still commonly used. So I have studied the full performance solution of the mainstream L2 switches with all-optical ports. I would like to share this with you and hope it will be useful to you. Recently, the F-engine S2200F series all-optical ports, 10-Gigabit L2 switches and F-engine S2200G series all-optical ports, which are independently developed by beacon network, were officially introduced to the market, this is an important step in improving the Ethernet switch Product Lin

Note that, the starting address does not include sfp and ret) Bp and sp are based on the following operating mechanisms: 1. The called function first defines the original bp push as
