Transcription is the first step of gene expression, in which a particular segment of DNA is copied to RNA by the enzyme RNA polymerase (RNAP). Despite many details of the complex interactions between DNA and RNA synthesis disclosed experimentally, much of physical behavior of transcription remains largely unknown. Understanding torsional mechanics of DNA and RNAP together with its nascent RNA and...
Railway clearance detection system based on rotating laser scanner sensors was designed for the realization of non-contact detection of railway clearance. In the system, in order to acquire and synchronize the data of Laser scanner sensors, gyroscope, position transducers and speed sensor, the FPGA-based PCI data acquisition synchronization card was designed. This paper describes the hardware design...
