Two endo-beta-1,4-glucanase components (YEG1 and YEG2) of the endogenous cellulase from the Japanese subterranean termite, Reticulitermes speratus, were purified to homogeneity using gel filtration and hydroxylapatite chromatography, and their enzymatic properties were investigated. Using sodium dodecyl sulphate-polyacrylamide gel electrophoresis(More)
This paper is a critique of version three of Joonmo Kim’s paper entitled “P 6= NP by Modus Tollens.” After summarizing Kim’s proof, we note that the logic that Kim uses is inconsistent, which provides evidence that the proof is invalid. To show this, we will consider two reasonable interpretations of Kim’s definitions, and show that “P 6= NP” does not seem(More)
alpha-Lactalbumin was isolated from the whey fraction of platypus (Ornithorhynchus anatinus) milk by successive ion-exchange, hydrophobic interaction and gel-permeation chromatography. The purified protein modified the action of partially-purified galactosyltransferase from platypus milk to promote the synthesis of lactose, but had very little modifier(More)
In this paper, we report the results of Monte Carlo simulations of the adsorption of neon, argon, methane and carbon dioxide in carbon nanohorns. We model the nanohorns as an array of carbon cones and obtained adsorption isotherms and isosteric heats. The main sites of adsorption are inside the cones and in the interstices between three cones. We also(More)
In this paper we discuss the Erdős-Falconer distance problem. The classical Erdős distance problem in R, d 2, asks for the smallest possible size of (E) = {|x y| : x, y 2 E} with E ⇢ R a finite set. An analogous problem is the Falconer distance problem which asks how large does the Hausdor↵ dimension of a compact set E ⇢ R, d 2, needs to be to ensure that(More)
Goldreich and Izsak (Theory of Computing, 2012) initiated the research on understanding the role of negations in circuits implementing cryptographic primitives, notably, considering one-way functions and pseudo-random generators. More recently, Guo, Malkin, Oliveira and Rosen (TCC, 2014) determined tight bounds on the minimum number of negations gates(More)
