Thermonuclear reaction rate of O17(p,γ)F18 [PDF]

open access: yes, 2005
The O17(p,γ)F18 and O17(p,α)N14 reactions have a profound influence on hydrogen-burning nucleosynthesis in a number of stellar sites, including red giants, asymptotic giant branch (AGB) stars, massive stars, and classical novae.

Measurement of the O17(p,α)N14 cross section at stellar energies [PDF]

open access: yes, 1995
The cross section for the astrophysically important O17(p,α)N14 reaction was measured at proton energies of 75 and 65 keV. Thick, high-purity Ta2O5 targets (77% enriched O17) and large-area detectors were used with beam currents of 0.45 mA.

Cysteine Thioaldehydes: Photolytic Generation, Reactivity, and Biological Implications

open access: yesAngewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Photolysis of cysteine phenacylsulfides bearing non‐conjugating electron‐withdrawing substituents leads to high conversions into cysteine thioaldehydes through a Norrish type‐II pathway. This methodology enabled the study of the aqueous reactivity of these important biosynthetic intermediates, which, depending on peptide sequence, pH and buffer ...

Artificial intelligence and unemployment in high-tech developed countries: New insights from dynamic panel data model

open access: yesResearch in Globalization, 2023
This study examines the effect of artificial intelligence on unemployment in high-tech developed countries. While artificial intelligence is more discussed in futuristic aspects, comprehensive empirical studies are limited in the literature.

Remeasurement of the 193 keV resonance in O17(p,α)N14 [PDF]

open access: yes, 2007
A recently discovered resonance at 193 keV determines the thermonuclear rates of the O17 +p reactions at temperatures important for the nucleosynthesis in classical novae (T=0.1-0.4 GK).

Measurement of O17(p,γ)F18 between the narrow resonances at Erlab=193 and 519keV [PDF]

open access: yes, 2010
The O17(p,γ)F18 reaction sensitively influences hydrogen burning nucleosynthesis in a number of stellar sites, including classical novae. These thermonuclear explosions, taking place in close binary star systems, produce peak temperatures in the range of
