We survey recent work on the elliptic curve discrete logarithm problem. In particular we review index calculus algorithms using summation polynomials, and claims about their complexity.

INSPECTION OF the Hodgkin’s disease (HD) mortality curve (Fig 1) gives cause for satisfaction with the progress of the past 30 years. United States mortality, which remained above 1.8 per 100,000 per year in the 1950s and early 1960s, had decreased to 0.47 by 1994.1 The most recent 5-year survival figure is 81%.2 Whereas HD accounted for 30% of total lymphoma deaths in 1950, it accounted for on...

three activated carbons are synthesized in a rotary reactor at different activation times. the adsorption isotherms of the samples are measured the pore size distribution of the samples is determined using combined saito and foley method, bjh method. an average potential function has been determined inside the cylindrical pores. the effect of activation time on the pore size distribution sample...

Phosphorylation-induced expression or modulation of a functional protein is a common signal in living cells. Many functional proteins are phosphorylated at multiple sites and it is frequently observed that phosphorylation at one site enhances or suppresses phosphorylation at another site. Therefore, characterizing such cooperative phosphorylation is important. In this study, we determine a temp...
