A heterobimetallic complex, in which a RuCl2(acetone) (PPh3)(2) fragment is connected via three chloro bridges to a (eta(4)-C4Ph4CO)RhCl fragment, has been identified as a potent catalyst precursor for the Oppenauer-type oxidation of alcohols. With 0.1-0.5 ...
The purpose of this paper is to present a detailed characterization of a dual-wavelength VCSEL - the BiVCSEL. This device consists of two active optical cavities, which share a coupling mirror and can be independently electrically pumped. We present the ou ...
Eight sesquiterpenes, four stilbene derivs. along with two lignans have been isolated from lipophilic fraction of stems of Dendrobium moniliforme (Orchidaceae). Among the eight sesquiterpenes, one allo-aromadendrane-type (I) and four picrotoxane-type sesqu ...
Mutual information is an attractive registration criterion because it provides a meaningful comparison of images that represent different physical properties. In this paper, we review the shortcomings of three published methods for its computation. We iden ...
The objective of this paper is to identify the behavioral issues arising in the context of pedestrian dynamics, analyze how they have been addressed in the literature and propose some potential research tracks. We particularly focus on an application in th ...
The electrolytic cond. and soln. viscosity of some strong polycations, which possess the ammonium quaternary centers either attached to an acrylic macromol. chain (polycation PDMAEMQ type), or in the backbone (polycation PCA type), have been measured to id ...
Assessing and comparing the performance of watermarking algorithms is di cult.The visibility of the watermark is an important aspect in this process.In this paper,we propose two metrics for evaluating the visual impact of video watermarks.Based on several ...
PROSITE [Bairoch and Bucher (1994) Nucleic Acids Res., 22, 3583-3589; Hofmann et al. (1999) Nucleic Acids Res., 27, 215-219] is a method of identifying the functions of uncharacterized proteins translated from genomic or cDNA sequences. The PROSITE databas ...
This study is designed to understand how to facilitate children's conceptual growth about plants using digital technology. Fifteen 4 and 5 year old children were interviewed to identify their understandings about plant growth and reproduction. Misunderstan ...
In this paper we present an experimental study in the identification of an industrial hybrid system. Piecewise ARX models, that consist of a number of ARX models, together with the partition of the regressor space into regions where each of the models is v ...
