The notion of “relativistic finance” became ingrained in the public imagination and has been asserted many mass-media reports. However, despite an observed drive most reputable Wall Street firms to establish their servers ever closer trading hubs, there is surprisingly little concrete information related relativistic delay orders. There underlying assumption that faster electronics are always b...

With the transmission of COVID-19 epidemic at home and abroad, this paper considers spread process in China, improves classic SEIR model, establishes a multistage time-delay control model (MTCM) for transmission. The MTCM divides into three periods: outbreak period, period steady period. classical improved SEQIR ? correspond to periods. was adopted yielded results that were consistent with obse...

We investigate the re-amplification and reshaping using nonlinear optical loopmirrors in a 10-Gb/s non-return-to-zero grating-compensated dispersion-managed transmission line with standard fibers. A large improvement of the system performance is achieved.

Feasible region is a simple and optimal framework for scheduling the transmission of data with deadlines. In this paper, we establish the fundamental relationship between the bandwidth requirement and the initial delay in feasible-region-based transmission scheduling. The relationship represents the optimal band-width/delay tradeoo. In the process, we identify the essential bandwidth, the exact...
