Active Anomaly Detection for Key Item Selection in Process Auditing [PDF]
, 2022 Process mining allows auditors to retrieve crucial information about transactions by analysing the process data of a client. We propose an approach that supports the identification of unusual or unexpected transactions, also referred to as exceptions ...

The s-process Nucleosynthesis [PDF]
Proceedings of the International Astronomical Union, 2005 Theoretical as well as observational aspects of the s-process nucleosynthesis are reviewed. The classical site-independent s-process model as well as the s-process in massive stars are shortly described. A special attention is paid to the nucleosynthesis taking place in AGB stars and the extra-mixing invoked to explain the production of neutrons in the

Universe, 2022 The foundations of stellar nucleosynthesis have been established more than 70 years ago. Since then, much progress has been made, both on the theoretical side, with stellar evolution and nucleosynthesis models of increasing complexity, using more and ...

Towards stable and highly active IrO2 catalysts supported on doped tin oxides for the oxygen evolution reaction in acidic media [PDF]
E3S Web of Conferences, 2022 Iridium oxide is the preferred catalyst for water oxidation but it is required to maximize its utilization to deploy Proton Exchange Membrane Water Electrolyzers (PEMWEs) into the large-scale applications panorama. A promising pathway for dispersing this

Molybdenum Isotope Dichotomy in Meteorites Caused by s-Process Variability
, 2021 Molybdenum isotopes measured in most individual presolar silicon carbide grains are dominated by s-process contributions from the helium intershells of asymptotic giant branch (AGB) stars.

Universe, 2022 The (n,α) reaction contributes in many processes of energy generation and nucleosynthesis in stellar environment. Since experimental data are available for a limited number of nuclei and in restricted energy ranges, at present only theoretical studies ...

The origin of s-process isotope heterogeneity in the solar protoplanetary disk [PDF]
Nature Astronomy, 2019 Rocky asteroids and planets display nucleosynthetic isotope variations that are attributed to the heterogeneous distribution of stardust from different stellar sources in the solar protoplanetary disk.

Tạp chí Khoa học Đại học Huế: Khoa học Tự nhiên, 2021 The W isotopic compositions have been investigated within the classical approach to the s-process nucleosynthesis. The Maxwellian averaged neutron capture cross-sections (MACS) adopted in the calculation are obtained from the TALYS-1.9 code with four ...

, 2006 Bioleaching processes of three zinc sulphides (marmatite, sphalerite and ZnS synthetically prepared) with Acidithiobacillus ferrooxidans and a moderately thermoacidophilic iron-oxidizing bacterium (MLY) were investigated by leaching experiments and ...

NuGrid stellar data set – III. Updated low-mass AGB models and s-process nucleosynthesis with metallicities Z= 0.01, Z = 0.02, and Z = 0.03 [PDF]
Monthly notices of the Royal Astronomical Society, 2019 The production of the neutron-capture isotopes beyond iron that we observe today in the Solar system is the result of the combined contribution of the r-process, the s-process, and possibly the i-process. Low-mass asymptotic giant branch (AGB) (1.5 < M/
