The solution of convex Mixed Integer Quadratic Programming (MIQP) problems with a general branch{and{bound framework is considered. It is shown how lower bounds can be computed eeciently during the branch{and{bound process. Improved lower bounds such as the ones derived in this paper can reduce the number of QP problems that have to be solved. The branch{and{bound approach is also shown to be s...

Unligated side branches of the left internal mammary artery (LIMA) have been described in the literature as a cause of coronary steal resulting in angina. Despite a number of studies reporting successful side branch embolization to relieve symptoms, this phenomenon remains controversial. Hemodynamic evidence of coronary steal using angiographic and intravascular Doppler techniques has been supp...

As processor pipelines get deeper and wider and instruction windows get larger, the branch misprediction penalty increases. Predication has been used to reduce the number of branch mispredictions by eliminating hard-to-predict branches. However, with predication, the processor is guaranteed to fetch and possibly execute useless instructions, which sometimes offsets the performance advantage of ...

According to a folk theorem, every program can be transformed into a program that produces the same output and only has one loop. We generalize this to a form where the resulting program has one loop and no other branches than the one associated with the loop control. For this branch, branch prediction is easy even for a static branch predictor. If the original program is of length κ, measured ...

Marangoni convection is investigated in cylindrical column using a liquid with Pr=4. The present results are targeting on the study of the non-linear characteristics of the flow under zero-gravity conditions. The transitions to periodic, quasi-periodic and chaotic flows are investigated numerically. The 3-D oscillatory flow is a result of a supercritical Hopf bifurcation and the periodic orbit ...

A method for the simultaneous alignment of a very large number of sequences using simulated annealing is presented. The total running time of the algorithm does not depend explicitly on the number of sequences treated. The method has been used for the simultaneous alignment of 1462 human intron sequences upstream of the intron-exon boundary. The consensus sequence of the aligned set together wi...
