In this paper, we present an access method called branch index for query processing of the aggregation hierarchy as a tree in object-oriented databases. The algorithm of branch generation will be proposed to generate all branches for the tree aggregation of classes in the database. For each branch, the information of linking objects is stored so that class traversal methods can be eliminated. U...

acute myocardial infarction (mi) during pregnancy is rare and mi due to prinzmetal's angina is much rarer. we present a 35-year-old, obese, multigravida, and pre-eclamptic woman, who developed acute anterior wall mi at the 30th week of gestation. on coronary angiography, the second obtuse marginal branch was totally occluded and the right coronary artery (rca) was normal. three days later, she ...

The performance and hardware complexity of superscalar architectures is hindered by conditional branch instructions. When conditional branches are encountered in a program, the instruction fetch unit must rapidly predict the branch predicate and begin speculatively fetching instructions with no loss of instruction throughput. Speculative execution increases hardware cost, since speculative inst...

The dolphin mystique. Throughout the ages, an enduring mystique has developed around dolphins. Even today some people continue to impute dolphins with mystical abilities such as extra-sensory perception and, in alternative medicine circles, special healing powers. An entire industry in ‘dolphinassisted therapy’ has been founded on the idea that dolphins have the capacity to heal illnesses throu...
