100 000 quinacrine nonsurgical female sterilizations have been completed over the past decade involving transcervical insertion of quinacrine (252 mg) as pellets by one, two or three monthly insertions. No deaths have been reported and serious complications are far fewer than for surgical sterilization. Sideeffects are mild and transient. Efficacy has improved from 3 pregnancy failures per 100 ...

1. Drawing balls without replacement (20 pts). Suppose that we have an urn containing one red ball and n − 1 white balls. Each time we draw a ball at random from the urn without replacement (so after the n-th drawing, there is no ball left in the urn). X i = 1 if the i-th ball is red, 0 otherwise.

2. Polya’s urn. Suppose we have an urn containing one red ball and one blue ball. We draw a ball at random from the urn. If it is red, we put the drawn ball plus another red ball into the urn. If it is blue, we put the drawn ball plus another blue ball into the urn. We then repeat this process. At the n-th stage, we draw a ball at random from the urn with n+1 balls, note its color, and put the ...

To elucidate the geometric structure of putative room-temperature superconductor, carbonaceous sulfur hydride (C-S-H), at high pressure, we present results an extensive computational search bulk C-S-H 250 GPa. Using minima hopping prediction method coupled to GPU-accelerated sirius library, more than 17 000 local with different stoichiometries in large simulation cells were investigated. Only 2...

Two trials using a total of 1,484 Ross male broilers were conducted to study the effect of air velocities of 180 and 120 m/min versus still air (<15 m/min) on BW gain (BWG) and feed:gain from 3 to 7 wk of age. Broilers were raised in a common environment to 3 wk of age. The experimental facility was a closed sided house containing eight wind tunnel floor pens and six floor pens. There were two ...
