    Notes: The Synchrotron Medical Research Facility (SMERF) at the National Synchrotron Light Source has been completed and is operational for human coronary angiography experiments. The imaging system and hardware have been brought to SMERF from the Stanford Synchrotron Radiation Laboratory where prior studies were carried out. SMERF consists of a suite of rooms at the end of the high-field superconducting wiggler X17 beam line and is classified as an Ambulatory Health Care Facility. Since October of 1990 the coronary arteries of five patients have been imaged. Continuously improving image quality has shown that a large part of both the right coronary artery and the left anterior descending coronary artery can be imaged following a venous injection of contrast agent.

    Monochromator harmonic content measurements and calculations at energies above 20 keV : Proceedings of the 4th international conference on synchrotron radiation instrumentation (1992)

    Notes: Measurements of the harmonic content from single- and double-crystal silicon monochromators have been made in the 20- to 100-keV range at the X17 superconducting wiggler beam line at the NSLS. These measurements are compared with calculations which estimate the monochromatic beam harmonic content and the detection system efficiency with good agreement. At high photon energies ((approximately-greater-than)20 keV), the scattering of x rays from an amorphous scatterer is dominated by the inelastic Compton process. At large scattering angles this will completely overwhelm the more forward directed elastic scattering. The Compton x-ray energy shift is large enough to make the distinction between elastic and Compton scattering unambiguous when a spectrum is acquired with a solid-state detector. This shift, which is energy dependent, allows the measurement of the relative harmonic intensity in a way that is not affected by pulse pileup in the detector and electronics. The present measurements were done to assess the level of harmonic contamination from two monochromator systems both used on the X17 beam line: the single-crystal-type monochromator for the digital subtraction coronary angiography project; and the double-crystal monochromator being developed for the multiple energy computed tomography (MECT) project and the Materials Science program.

    Cores and large cores when population varies (1990)
    Springer
    International journal of game theory 19 (1990), S. 219-232

    Notes: Abstract In a TU cooperative game with populationN, a monotonic core allocation allocates each surplusv (S) among the agents of coalitionS in such a way that agenti's share never decreases when the coalition to which he belongs expands. We investigate the property of largeness (Sharkey [1982]) for monotonic cores. We show the following result. Given a convex TU game and an upper bound on each agent' share in each coalition containing him, if the upper bound depends only upon the size of the coalition and varies monotonically as the size increases, then there exists a monotonic core allocation meeting this system of upper bounds. We apply this result to the provision of a public good problem.

    Fair division under joint ownership: Recent results and open problems (1990)

    Notes: Abstract Two microeconomic models of joint ownership are discussed: the division of unproduced commodities and the joint production of a single output by a single input. In both models the two principal interpretations of fairness are Equal Split Guarantee (ESG) and No Envy (NE). When combined with Pareto optimality these axioms are however not compatible with some appealing monotonicity properties. Resource monotonicity (more cake to share makes everyone happy) is incompatible with either ESG or NE, and Population Monotonicity (one more mouth to feed makes everyone unhappy) is incompatible with NE. This in turn suggests three disjoint classes of fair solutions. This paper contains very few new results, it is mostly a survey of recent literature.
