In this paper we show that both of the Green-Schwarz anomaly factorization formulafor the gauge group E8 × E8 and the Hoˇrava-Witten anomaly factorization formula for the gaugegroup E8 can be derived ...
The E8 Lattice and Error Correction in Multi-Level Flash Memory
E8 Lattice Error Correction Multi-Level Flash Memory

A construction using the E8 lattice and Reed-Solomon codes for error-correction in flash memory is given. Since E8 lattice decoding errors are bursty, a Reed-Solomon code over GF(28) is well suited. T...

转基因技术的发展，使转基因植物口服疫苗的研制成为可能。外源基因能否在转基因植株中高效稳定表达，是其能否作为口服疫苗的前提条件。基因表达的程序、时间和位置在不同层次上受不同的调节因素控制，这种调控机制不仅决定基因表达水平，也决定基因表达的时空顺序。作为最主要的一种转录调节方式，植物启动子有着十分重要的作用，采用什么样的启动子对于外源基因的表达至关重要。组织特异性表达启动子，如在果实、种子等器官特异表...
