A dominating set of a graph is a vertex subset that any vertex belongs to or is adjacent to. Among the many well-studied variants of domination are the so-called paired-dominating sets. A paired-dominating set is a dominating set whose induced subgraph has a perfect matching. In this paper, we continue their study. We focus on graphs that do not contain the net-graph (obtained by attaching a pe...

We define a ranked trigroupoid as a natural followup on the idea of a ranked bigroupoid. We consider the idea of a derivation on such a trigroupoid as representing a two-step process on a pair of ranked bigroupoids where the mapping d is a self-derivation at each step. Following up on this idea we obtain several results and conclusions of interest. We also discuss the notion of a couplet (D, d)...

Furin inhibitors are promising therapeutics for the treatment of cancer and numerous infections caused by bacteria and viruses, including the highly lethal Bacillus anthracis or the pandemic influenza virus. Development and improvement of inhibitors for pharmacological use require a detailed knowledge of the protease's substrate and inhibitor binding properties. Here we present a novel preparat...

Twenty-four species of mites were found associated with Ips typographus (Linnaeus) collected from pheromone traps in Sweden, bringing to 38 the total recorded for this scolytid. Because three of the species are parasites, it may be possible to use them in biological control of I. typographus. Couplets from an earlier key to these mites in south Germany have been modified to include three of the...

My intent is to focus on the project and methodology of phenomenology in a manner that is not overly technical and that may help others to further elaborate on or question the singular features that make phenomenology into a unique qualitative form of inquiry. I pay special attention ...
