For students of medieval proportional systems who lack such documentary evidence as James Ackerman had, in relative abundance, for his groundbreaking 1949 study of the Cathedral of Milan, the only choice has been to turn to the buildings. Yet Ackerman warned that such an exercise was destined to fail: ‘the analysis of remaining monuments,’ he wrote, ‘provides insufficient evidence for [the] tas...

This article describes reproducibility of a single-step automated β-galactosidase, and the equivalence of its data to the traditional assay ("Experiments in Molecular Genetics" [1]). This was done via a pairwise comparison of both methods using strains with Miller Unit [MU] values ranging from 0 to over 2000. The data presented in this article is associated with the research article entitled "A...

The ability of membrane proteins to sense and respond to changes in membrane voltage is critical for a vast array of biological processes, from generating and propagating the nerve impulse to excitation–secretion coupling. Hodgkin and Huxley (1952) were the first to characterize voltage-activated potassium (Kv) and sodium (Nav) currents, but the common architecture of voltage-activated cation c...
