We develop an algorithm for bounding the rank of elliptic curves in the family y 2 = x 3 −B x, all of them with torsion group Z/(2 Z) and modular invariant j = 1728. We use it to look for curves of high rank in this family and present four such curves of rank 13 and 22 of rank 12.
Stable maintenance replication is characteristic of the latency phase of HPV infection, during which the viral genomes are actively maintained as extrachromosomal genetic elements in infected proliferating basal keratinocytes. Active replication in the S-phase and segregation of the genome into daughter cells in mitosis are required for stable maintenance… (More)
PCFORT is a compiler for the FORTRAN language designed to fit as a building block into a PASCAL oriented environment. It forms part of the programming systems being developed for the S-l multiprocessor. It is written in PASCAL, and generates P-code, an intermediate language used by transportable PASCAL compilers to represent the program in a simple form.… (More)
