RD-flatness and RD-injectivity

It is proved that every commutative ring whose RD-injective modules are Σ-RD-injective is the product of a pure semi-simple ring and a finite ring. A complete characterization of commutative rings for which each artinian (respectively simple) module is RD-injective, is given. These results can be obtained by using the properties of RD-flat modules and RD-coflat modules which are respectively th...

DOE medical research funding cut in FY 2006 budget; SNM calls for nuclear medicine community action.

Funding decisions

Funding decision is one of the financial strategic decisions of a corporation. There are also two other finan-cial strategic decisions that a corporation faces, the investment and the dividend decision. This paper de-scribes briefly the investment and the dividend decision, although its main focus is on funding decision. In de-scribing the funding decision the researchers will first explain the...

Ideal observer for heading judgments

Several aspects of the viewing situation affect the ability to determine heading from optical flow. These include the amount of depth variation and number of texture elements in the scene, the location and amount of the visual field stimulated, and the position of the focus of expansion within the stimulus. Without a quantification of the discrimination information provided by the stimuli prese...
