A series of retroviral vectors encoding human mdr1 gene alone as well as in combination with either human mgmt gene or human mutant Ser31-dhfr gene are engineer
Using a well-known result of polynomial over the finite field Fp, we show that the Euler-Fermat theorem holds in ZN[x]. We present a multi-dimension RSA cryptos
The genetic algorithm and marching method are integrated into a novel algorithm to solve the surface intersection problem. By combining genetic algorithm with l
