Stable dark red (M = Al) or dark green (M = Ga) neutral radicals {[PhB(mu-NtBu)2]2M} are obtained by the oxidation of their corresponding anions with iodine, and EPR spectra supported by DFT calculations show that the spin density is equally delocalized over all four nitrogen atoms in these spiroconjugated systems.

We establish formulae for the Iwasawa invariants of Mazur–Tate elements of cuspidal eigenforms, generalizing known results in weight 2. Our first theorem deals with forms of “medium” weight, and our second deals with forms of small slope. We give examples illustrating the strange behavior which can occur in the high weight, high slope case.

The correlation consistent composite approach (ccCA) has been applied to the G3/05 training set of 51 energetic properties for the atoms and molecules that contain the 4p elements, Ga-Kr. When atomic and molecular first-order spin orbit coupling corrections are added to open shell atoms and molecules, the ccCA has a mean absolute deviation from experiment (MAD) of 0.95 kcal mol(-1), an improvem...

Th& article departs &ghtZy from previous ones in the annual series on national heaZth expenditures. Data were fomerly presented for calendar years beginning with 1950. This year the article presents historical data back to 1929, on both a fiscal-year and calendar-year basis. Detailed fiscal-year data by source of funds and type of program are reported regularly in the annual report on sociaZ we...

The authors’ purpose in this study was to identify social structural predictors of receiving emotional support from parents early in life and structural factors responsible for variations in the associations between early parental support and adult health status. Data from a US representative sample of 2,786 adults aged 25–74 years suggest that men, non-Whites, and individuals from socioeconomi...

Ethnic German Immigration from Eastern Europe and the former Soviet Union to Germany: the Effects of Migrant Networks This paper employed a widely accepted theoretical concept, the ‘theory of migrant networks’ to look at the recent immigration and absorption experience of ethnic Germans (Aussiedler) from Eastern Europe and the former Soviet Union in Germany. Consistent with network theory, the ...
