I summarize recent experimental results on B to charmonium decays. Decays of B meson to final states that include charmonium states play an important role in the study of CP violation at B-factories. The decay modes BCP → J/ψKS, ψ(2S)KS, χc1KS, ηcKS, J/ψKL and J/ψK (K → KSπ ) have been used for sin2φ1 measurements [1] [2] [3] [4] [5]. These two-body decay modes are dominated by the color suppre...

      Wetability of biocompatible polymers can be improved by plasma surface modification. The purpose of this study was to surface modify an experimental poly (dimethylsiloxane) rubber (PDMS) material in order to improve its wetability and biocompatibility. Surface properties of the PDMS were characterized using contact angles measurement for wetability analysis. Samples of experimental silico...

In recent years, plasma treatments have given good results since they offer high technological efficiency with low waste generation. One of the most important characteristics of plasma methods is their action only on a thin surface layer, whereas the bulk of sample remains unchanged and the modified material keeps its chemical and mechanical properties. In this research, polyurethane membrane s...

Bulk loading refers to the process of creating an index from scratch for a given data set. This problem is well understood for B-trees, but so far, non-traditional index structures received modest attention. We are particularly interested in fast generic bulk loading techniques whose implementations only employ a small interface that is satisfied by a broad class of index structures. Generic te...
