Curious people typically wonder at some point in their lives whether they might have been different if they had had different experiences while growing up. It is clear to all of us from casual observation that some of our characteristics are affected by our experiences; children growing up in Calais, France typically speak French, while children growing up just across the English Channel in Dov...

The instabilities that are believed to play an important role in the supernova mechanism are reviewed. We then investigate the dynamics of two of these instabilities, prompt convection and neutron ngers, and its consequences for the supernova outcome. We nd that prompt convection occurs immediately after shock propagation and is primarily entropy driven. A number of detailed one-dimensional sph...

A 40-year-old woman presented to a tertiary-care facility on the 11th of October 2004, having been referred from a private-health clinic for continued treatment of thyrotoxicosis. The referring doctor had started her on carbimazole, 60 mg daily 11 months earlier. She discontinued treatment after three months for fi nancial reasons. She was referred to the state tertiary facility because the fee...

The use of Implanon®/Nexplanon® has been growing in general practice and family planning clinics since its introduction in 1999. It is the most effective hormonal contraceptive available today, preventing 999 in 1000 pregnancies over its recommended period of use. I have been practising a technique for the removal for the past 8 years that I have found to be easier than the traditional one. Wit...

background: in radiation treatment of moving targets located in thorax region of patient body, the delivered dose does not match with the planned treatment, resulting in some over and under dosage in the tumor volume, as a function of motion magnitude and frequency. several efforts have been done to investigate the target motion effects on dose distribution in the target and surrounding normal ...

We present an algorithm called nger tracking for in-hand manipulation of three dimensional objects with independent robot ngers. We describe and analyze the diierential control for nger tracking and extend it to on-line continuous control for a set of cooperating robot ngers. We show experimental data from a simulation. Finally, we discuss global control issues for nger tracking and compute low...

8 allows the algorithm to operate on the same type of objects as the previous algorithm. More speciically, boundary following is achieved by keeping the distance detected by the closest sensor small, and the additional requirement of axis normality is satissed by keeping equal the distance indicated by the two sensors placed at the jaws ends. It remains to be seen how these algorithms perform i...
