Which isotopes should we choose? Entropy-based feature ranking enables evaluation of the information content of stable isotopes in archaeofaunal material.doi:10.1002/rcm.8692Andrea GhringMarkus MauderPeer KrgerGisela GrupeJohn Wiley & Sons, Ltd...
Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of ...
The industry is such that not only do insurance companies deny 51% of claims,they have enacted policies forbidding people from paying for the critical medication they need out of pocket, lest the insurance company lose control and revenue.“Either you pay us, or you pay no one,” is a lin...
STABLE isotopesGAUSSIAN mixture modelsCHEMICAL bondsRANKINGRationale Methods for multi‐isotope analyses are gaining in importance in anthropological, archaeological, and ecological studies. However, when material is limited (i.e., archaeological remains), it is obligatory to decide a priori which isotopic...
Inorganic additive, which is labeled by heavy and stable isotopes, where the labeling is firmly incorporated in the additive, is new. An independent claim is included for a method for the production of the inorganic additive.Eickschen, Ralf...
Stable hydrogen and oxygen isotopes provide a powerful technique for quantifying the proportion of root water uptake (RWU) from different potential water sources. Although many models coupled with stable isotopes have been developed to estimate plant water source apportionment, inter-comparisons of ...
1=f1+f2+f31=f1+f2+f3 (3) Here, the contributions of the three sources to the plant can be calculated with two isotope signatures. If the number of sources exceeds three sources, then the model is mathematically undetermined, with no unique solution [23]. The previous two classes of ap...
