Modeling structural and mechanical properties of intermetallic compounds and alloys requires detailed knowledge of their interatomic interactions. The first two papers of this series @Phys. Rev. B 56, 7905 ~1997!; 58, 8967 ~1998!# derived first-principles interatomic potentials for transition-metal ~TM! aluminides using generalized pseudopotential theory ~GPT!. Those papers focused on binary al...
Congeneric species often have similar ecological characteristics and use similar resources. These similarities may make it easier for them to co-occur in a similar habitat but may also lead to strong competitions that limit their coexistence. Hence, how do similarities in congeneric species affect their coexistence exactly? This study mainly used spatial point pattern analysis in two 1 hm2 plot...
A compilation of experimental animal data shows that neither delta13C(collagen) nor delta13C(apatite) nor Delta13C(CO-AP) indicate diagnostic reconstructions of diet, diet energy and diet protein. In contrast, plots of delta13C(collagen) against delta13C(apatite) provide a model of three regression lines (C3, C4, and marine diet protein) where position on each line indicates the energy source (...
The concept of a fractional base unit for the Kendrick mass defect (KMD) analysis of polymer ions is introduced for the first time. A fraction of the ethylene oxide (EO) repeat unit (namely EO/8) has been used for the KMD analysis of a poly(ethylene oxide) and found to amplify the variations of KMD between monoisotopic and 13C isotopes, producing an isotopically resolved KMD plot at full scale ...

The distribution of species and communities in relation to environmental heterogeneity is a central focus in ecology. Co-occurrence of species with similar functional traits is an indication that communities are determined in part by environmental filters. However, few studies have been designed to test how functional traits are selectively filtered by environmental conditions at local scales. ...
A modified Freeman-Murray-Richards (FMR) correlation for the analysis of 59C0 NMR shielding parameters, 6(59C0) us. ( A V ~ , ~ ) ' / ' / A E ~ ~ , is formulated by combining the Ramsey shielding theory and the Townes and Dailey theory for the calculation of the nuclear quadrupole coupling constant. It is demonstrated that the experimental 59C0 NMR half-height linewidth is a useful parameter to...
