We present a taxonomy of myopic stability concepts for hedonic games in terms of deviations, and discuss the status of the existence problems of stable coalition structures. In particular, we show that contractual strictly core stable coalition structures always exist, and provide su¢ cient conditions for the existence of contractually Nash stable and weak individually stable coalition structur...

It is held as axiomatic that an understanding of the mechanism of the passage of substances from the blood stream to the gastric lumen must include a knowledge of the passage of these same substances in the reverse direction. In the previous paper (1), the absorption of radioactive sodium (Na24) from the stomach was reported. Tangible amounts of Na24 placed in a stomach pouch were found after 1...

ISIDORE S. EDELMAN, M.D. TO DATE, deuterium oxide (D20) has been the most satisfactory and accurate tracer substance for body water: its diffusion characteristics have been thoroughly studied, and its reliability as a tracer for body water by the dilution technic has been established.' 2 However, the technical difficulty of deuterium analysis by the falling drop method and the labor and expense...

Near-infrared spectrometry has been successfully used to determine association binding constants between phenol and alpha-, beta- and gamma-cyclodextrin (CD) in [butylmethylimidazolium][chloride] room-temperature ionic liquid (RTIL). It was found that adding CD into the RTIL solution of phenol resulted in an enhancement in the absorption coefficient of the stretching overtone of the aromatic C-...

Function and structure of adult pancreatic islets are determined by early postnatal development, which in rats corresponds to the first month of life. We analyzed changes in blood glucose and hormones during this stage and their association with morphological and functional changes of alpha and beta cell populations during this period. At day 20 (d20), insulin and glucose plasma levels were two...

The reactions of Sc+ and Ti+ with D20 are studied as a function of translational energy in a guided ion beam tandem mass spectrometer. Both ions react to form three ionic products: MD+, MO', and MOD'. MO+ formation occurs exothermically by dehydrogenation of D20, even though this reaction is spin forbidden for reaction of ground state M+ in both systems. In the titanium system, the effect of el...
