Hash Hashemian: Visionary leadership
As Dr. Hashem M. “Hash” Hashemian prepares to step into his term as President of the American Nuclear Society, he is clear that he wants to make the most of this unique moment.
A groundswell in public approval of nuclear is finding a home in growing governmental support that is backed by a tailwind of technological innovation. “Now is a good time to be in nuclear,” Hashemian said, as he explained the criticality of this moment and what he hoped to accomplish as president.

In photon transport calculations by a Monte Carlo method, the solution of the inverse Klein-Nishina cumulative distribution function for random selection of a photon energy upon Compton scattering is not practical; moreover, Koblinger's procedure cannot be applied for incoming photon energies less than . In this case the sampling rejection methods (SRMs), especially the nonuniform ones, represent a good alternative. A number of SRMs for the Klein-Nishina probability density function are presented; some of the methods have very high selection efficiencies. These techniques are tested within the bounds of computer time required for a successful selection. At least one of them is appreciably advantageous over those previously proposed.
