Distributed graph searching with a sense of direction
PublicationIn this work we consider the edge searching problem for vertex-weighted graphs with arbitrarily fast and invisible fugitive. The weight function w provides for each vertex v the minimum number of searchers required to guard v, i.e., the fugitive may not pass through v without being detected only if at least w(v) searchers are present at v. This problem is a generalization of the classical edge searching problem, in which one has...

Bismuth germanate and bismuth silicate glasses in cryogenic detectors.
PublicationStwierdzono, że przewodnictwo elektryczne redukowanych szkieł silnie zależy od temperatury, czasu reakcji i koncentracji Bi. Zależność przewodnictwa elektrycznego od temperatury jest dobrze opisana przez funkcję ĺ~exp[-(T0/T)n,gdzie n=1/4. Współczynnik emisji wtórnej elektronów jest praktycznie niezależny od stopnia redukcji ale znacznie rośnie po domieszkowaniu szkieł alkalicznymi jonami. Badania dowiodły, że modyfikowane...

An Alternative Proof of a Lower Bound on the 2-Domination Number of a Tree
PublicationA 2-dominating set of a graph G is a set D of vertices of G such that every vertex not in D has a at least two neighbors in D. The 2-domination number of a graph G, denoted by gamma_2(G), is the minimum cardinality of a 2-dominating set of G. Fink and Jacobson [n-domination in graphs, Graph theory with applications to algorithms and computer science, Wiley, New York, 1985, 283-300] established the following lower bound on the 2-domination...

Ho2Pd1.3Ge2.7 – a ternary AlB2-type cluster glass system
PublicationWe report a successful synthesis of a ternary AlB2-type intermetallic compound. The phase purity was obtained by fine-tuning the Pd-Ge ratio out of the idealized 1-3. Attempts to synthesize an Er analogue were not successful. We discuss the instability of the Er analogue based on the atomic size ratio and also suggest that the increased stability of Ho2Pd1+xGe3−x in the Pd-rich range likely stems from a combination of atomic size...
