This note describes a technique for generating large non-singular matrices with blocks of full rank. Our motivation to construct such matrices arises in the white-box implementation of cryptographic algorithms with S-boxes.

GTP:RNA guanylyltransferase catalyzes the initial reaction in the formation of “caps” at 5’ termini of mRNAs. The characteristics of the guanylation reaction have been studied using purified enzyme isolated from vaccinia virus. Guanylation requires a divalent cation (Mg2’), is stimulated by monovalent cations (Na+ and K+), and is unaffected by S-adenosylmethionine. The enzyme utilizes GTP as gu...

In this paper we look at the motivations of managers of small and medium sized enterprises (SMEs) to engage with climate change. The paper reports on an exploratory, qualitative study with managers of nine environmentally proactive SMEs in the East of England. The aim of the research was to study what motivated managers of SMEs to engage with environmental issues in general and with climate cha...

Cell-free extracts of Neurospora crassa mycelium catalyze the methylation of l-histidine to form hercynine (histidine betaine). The partially methylated compounds, alpha-N-methyl-l-histidine and alpha-N,N-dimethyl-l-histidine, are also methylated by the same enzyme preparation to form hercynine. All three methylation reactions are stimulated by the addition of S-adenosylmethionine.
