Nd and Sr isotopic studies of Australasian tektites provide info~ation on the age and provenance of the target materials and allow us to characterize the target area and the impact process leading to tektite formation. ENd values of australites, splash-form indochinites, and Muong Nong-type indochinites are indistinguishable within analytical uncertainty and average -11.5 cu. Depleted mantle Nd...

Trace-element and Nd-Sr-Pb isotopic data for mafic lavas from the Mascarene island of Mauritius reveal that the shield-stage Older Series (with 143Nd/144Nd = 0.512827 to 0.512853, 87Sr/86Sr = 0.70412 to 0.70433, and 206Pb/204Pb = 18.771 to 19.024) is geochemically very similar to the shield-building lavas of the younger island of Réunion. The post-shield Intermediate and Younger Series lavas of...

The Reinforcement Sensitivity Theory proposes that the Behavioral Approach System (BAS) comprises dopaminergic brain regions and underpins reward sensitivity causing impulsivity. It has been shown in a supraliminal priming task that highly reward sensitive subjects have a larger reaction time (RT) priming effect and make more commission errors to prime-incongruent targets. We adapted a similar ...

We present a theoretical study of the effect electron-electron interactions and Sr doping on electronic structure infinite-layer (Nd,Sr)NiO$_2$ using density functional+dynamical mean-field theory approach. In particular, we explore impact epitaxial compressive strain that experience films properties, magnetic correlations, exchange couplings. Our results reveal crucial importance orbital-depen...

Introduction: The crystallization age of Zagami has been well established by the Rb-Sr and Sm-Nd isochron techniques. Isotopic analysis on purified mineral fractions yield Rb-Sr ages of 178±3, 174±14, and 163±19 Ma [1-2], and a Sm-Nd age of 163±7 Ma [2]. Whole rock and leachate pairs have also been analyzed for U-Th-Pb isotopes and yield a Th-Pb age of 230±5 Ma and a U-Pb age of 229±8 Ma [3]. C...
