Detection of Elements at All Three r-process Peaks in the Metal-Poor Star HD 160617

, 2012
We report the first detection of elements at all three r-process peaks in the metal-poor halo star HD 160617. These elements include arsenic and selenium, which have not been detected previously in halo stars, and the elements tellurium, osmium, iridium,

Iowa Population Exposures to Metals and Metalloids in Well Water

Environmental Toxicology, EarlyView.
ABSTRACT Previous Iowa studies suggest low levels and chronic arsenic exposures are associated with prostate cancer. The rural Iowa population heavily relies on private wells for drinking water resources and thus is vulnerable to contaminants such as heavy metals found in well water.

Determination of strontium isotope ratios in plant samples by wet ashing digestion

Results in Earth Sciences
Strontium isotope provenance analysis has been widely applied across multiple disciplines, including archaeology, food science, and forensics. The establishment of bioavailable ⁸⁷Sr/⁸⁶Sr maps, known as isoscapes, which rely on a substantial number of ...

Using oxygen isotope analysis and a multi-isotopic approach in determining the region of origin of human remains [PDF]

, 2017
Multi-isotopic approaches have been used effectively to help provide estimated geographic origins for unidentified skeletal remains in cold case homicides and archaeological contexts, when DNA testing was not practical.

Magnetic‐lens‐generated polarized neutron beam with enhanced intensity and Q resolution for small‐angle neutron scattering

Journal of Applied Crystallography, EarlyView.
While maintaining or even improving Q resolution, a long array of short‐focal‐length magnetic lenses, with zero transmission loss and no diffuse scattering, successfully polarized and enhanced the intensity of neutron beams for small‐angle neutron scattering at momentum transfer Q > 0.1 nm−1.We installed a 30 mm‐bore 3.2 m‐long magnetic lens in the ...

Production of very-high-$n$ strontium Rydberg atoms

, 2013
The production of very-high-$n$, $n\sim300$-500, strontium Rydberg atoms is explored using a crossed laser-atom beam geometry. $n$$^{1}$S$_{0}$ and $n$$^{1}$D$_{2}$ states are created by two-photon excitation via the 5s5p $^{1}$P$_{1}$ intermediate state

Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Integrating Sr isotopes, microchemistry, and genetics to reconstruct Salmonidae species and life history

Archaeometry, EarlyView.
Abstract Recent approaches to fisheries research emphasize the importance of the coproduction of knowledge in building resilient and culturally mindful fisheries management frameworks. Despite widespread recognition of the need for Indigenous knowledge and historical reference points as baseline data, archaeological data are rarely included in ...
