The first explicit recognition of non-atmospheric Xe in terrestrial samples came from the analysis of CO 2-well gas in New Mexico, displaying an excess of 129 I-derived or primitive source 129 Xe and high content in 131-136 Xe due to the decay of 238 U. [38] At present, the excess of 129 Xe and 131-136 Xe has been widely observed in mid-ocean ...
Naturally occurring xenon (54 Xe) consists of seven stable isotopes and two very long-lived isotopes. Double electron capture has been observed in 124 Xe (half-life 1.8 ± 0.5(stat) ± 0.1(sys) × 10 22 years) [2] and double beta decay in 136 Xe (half-life 2.165 ± 0.016(stat) ± 0.059(sys) × 10 21 years), [7] which are among the longest measured half-lives of all nuclides.
[1] [2] 129 Xe is a stable, naturally occurring isotope of xenon with 26.44% isotope abundance. It is one of two Xe isotopes, along with 131 Xe, that has non-zero spin, which allows for magnetic resonance. 129 Xe is used for MRI because its large electron cloud permits hyperpolarization and a wide range of chemical shifts

Intel Parallel Studio XE was a software development product developed by Intel that facilitated native code development on Windows, macOS and Linux in C++ and Fortran for parallel computing. [2] Parallel programming enables software programs to take advantage of multi-core processors from Intel and other processor vendors.
Super Bowl LIX wasn’t just a decisive win for the Philadelphia Eagles — who steamrolled the Kansas City Chiefs with a 40-22 victory — it was also a night packed with fashion statements ...
