With the development of e-commerce over Internet, web service discovery received much interest. A critical aspect of web service discovery is web service similarity search or matchmaking. To enhance the similarity precision, several solutions that do not limit to a syntactic comparison of inputs and outputs of the compared services have been proposed ...

Chronometer for S-Process Nucleosynthesis
Nature Physical Science, 1973The importance of the short-lived s-process chronometer 205Pb, its relation to the mechanism of s-process nucleosynthesis and its implications for cosmochronology are discussed.

OWL-S Process Model Matchmaking
2010 IEEE International Conference on Web Services, 2010In this paper, we propose an approach for approximate matching of OWL-S process model. We also propose a similarity measure that captures structural and semantic differences between two process models. To do so, we reduce the process matching to a graph matching problem and we adapt existing algorithms for this purpose.

We argue that the solar-system σN curve can be best understood if the s-process is largely produced by stars in the mass range of M ∿ 2–4 MO. Several observations are then studied as indicators of the validity of this hypothesis. We find that isotopic Zr abundances and elemental (Ba/Sr) vs. (Ba/Nd) ratios are consistent with these conditions.

176Lu‐An s‐Process Thermometer
AIP Conference Proceedings, 1991The use of 176Lu as a cosmic clock has been in question since the possibility of a thermal coupling between the long‐lived ground state (t1/2=41⋅109 yr) and the beta unstable isomer with 3.68 hr half‐life was considered. This coupling requires induced transitions to higher lying states because direct transitions are highly forbidden by selection rules.

176Lu and s-Process Nucleosynthesis
Nature Physical Science, 1972THE elements heavier than those in the iron abundance peak have been divided into three groups1: s-process isotopes (formed by slow radiative capture of neutrons), r-process isotopes (formed by rapid radiative capture of neutrons) and p-process isotopes, which are rarer proton-rich isotopes formed by a still poorly understood mechanism which probably ...

The s process in massive stars
Progress in Particle and Nuclear Physics, 2007Abstract In the past decades considerable progress has been made in the understanding of the various processes responsible for the nucleosynthesis of the elements in stars. This holds especially for the main s process in low-mass AGB stars, which is largely responsible for the production of about half of the elemental abundances in the mass range ...
