Conjecture 1.1. Fix an integer g. Let B be a g-dimensional CM principally polarized abelian variety, and let x be the corresponding point in Ag,1(Q). Finally, let Z(End(B)) denote the center of the endomorphism ring of B. Then there exists a constant δg > 0 so that |Gal(Q/Q) · x| g Disc(Z(End(B)))g . Edixhoven established the desired lower bound for Hilbert modular surfaces in [3]. Recently, Pi...

The control of the expression of the pilin gene (pilE) in Neisseria gonorrhoeae under a wide variety of growth conditions has been studied. The expression of pilE was measured using transcriptional fusions between pilE and the gene encoding chloramphenicol acetyltransferase (CAT), and the level of pilin production was measured by Western blot analysis. Many of the conditions tested affected bot...

Type IV pili are an efficient and versatile device for bacterial surface motility. They are widespread among the beta-, gamma-, and delta-proteobacteria and the cyanobacteria. Within that diversity, there is a core of conserved proteins that includes the pilin (PilA), the motors PilB and PilT, and various components of pilus biogenesis and assembly, PilC, PilD, PilM, PilN, PilO, PilP, and PilQ....
