We present measures for bounding the instance-based complexity of AND/OR search algorithms for solution counting and related #P problems. To this end we estimate the size of the search space, with special consideration given to the impact of determinism in a problem. The resulting schemes are evaluated empirically on a variety of problem instances and shown to be quite powerful.

We analyze strong one-pion and radiative one-photon decays of heavy flavored baryons within a relativistic three-quark model. Employing the same parameters as were used for the description of the semileptonic decays of heavy baryons, we calculate the couplings of one-pion and one-photon transitions of both ground and excited heavy baryon states. We predict the decay rates for all relevant decay...

I report the following case only to show one more instance of the great value and utility of the new photography in aid of diagnosis and treatment in practical surgery. Mrs. B. consulted me on June 22nd with the following history. When retiring to bed on June 7th she felt a sharp pain in her foot, but did not know the cause until, after search,

OBJECTIVES To determine whether a sharp increase in Emergency Room (ER) visits at the Montreal Children's Hospital (MCH) during the week following the death of Natasha Richardson from a skiing-related head injury was a) statistically significant and b) related to media coverage of the event. We postulated that there would be less coverage in the French media and in centres west of Quebec. MET...
