Background: This study aimed to investigate the changes of serum zinc in term neonates who need major operation. Materials and Methods: In this study, 59 neonates who need major operation were studied. All patients underwent major surgical with high stress. The metabolic response to surgery was studied by measuring the serum zinc before and after surgery (24 hours and at discharge time postoper...
We present a space-efficient algorithm to compute the Hilbert class polynomial HD(X) modulo a positive integer P , based on an explicit form of the Chinese Remainder Theorem. Under the Generalized Riemann Hypothesis, the algorithm uses O(|D|1/2+ log P ) space and has an expected running time of O(|D|1+ ). We describe practical optimizations that allow us to handle larger discriminants than othe...
where the sum is taken over a complete set of residues for x modulo q and eq(t) = e2πit/q. The study of these sums is readily motivated by applications in analytic number theory and elsewhere. The first important estimates for sums in one variable appear in the work of Weyl (1916) on uniform distribution. This led to van der Corput’s method with applications to the zeta function, the divisor pr...
Let p be an odd prime. Assuming the Extended Riemann Hypothesis , we show how to construct O((log p) 4 (loglogp) ?3) residues modulo p, one of which must be a primitive root, in deterministic polynomial time. Granting some well-known character sum bounds, the proof is elementary, leading to an explicit algorithm.
