The specific activity of ribonucleotide reductase was found to increase significantly after deoxyribonucleic acid inhibition in seven species of bacteria investigated. This group of bacteria includes species with B12-dependent ribonucleotide reductase as well as some with an Escherichia coli-type ribonucleotide reductase.

A bstract We present a family of new M2-brane solutions in AdS 7 × S 4 that calculate toroidal BPS surface operators the $$ \mathcal{N} N = (2 , 0) theory. These observables are conformally invariant and not subject to anomalies so we able evaluate their finite expectation values at leading order large N . In...
