We introduce an algorithm that computes the prime numbers up to N using O(N/log logN) additions and N1/2+o(1) bits of memory. The algorithm enumerates representations of integers by certain binary quadratic forms. We present implementation results for this algorithm and one of the best previous algorithms.

Effects of ionic liquid structures on the aluminophosphate molecular sieve products in ionothermal synthesis process were investigated. The results showed that the possible structure-directing effect of ionic liquid might exist during ionothermal synthesis. Microwave heating was introduced into the ionothermal synthesis, which led to a fast and safe process for preparation of molecular sieves. ...
