Discovery of association rules has been found useful in many applications. In previous work, all items in a basket database are treated uniformly. We generalize this to the case where items are given weights to re ect their importance to the user. The weights may correspond to special promotions on some products, or the pro tability of di erent items. We(More)
Computerized physician order entry (CPOE) has had demonstrated benefits in error reduction and guideline adherence, but its implementation has often been complicated by disruptions in established workflow processes. We conducted an observational study of the healthcare team in an intensive care unit after the implementation of mandatory CPOE. We found that(More)
The farthest string problem (FARTHEST STRING) is one of the core problems in the field of consensus word analysis and several biological problems such as discovering potential drugs, universal primers, or unbiased consensus sequences. Given k strings of the same length L and a nonnegative integer d, FARTHEST STRING is to find a string s such that none of(More)
A supersymmetric way of imposing the constraint of no double occupancy in models with strong on-site Coulomb repulsion is presented in this paper. In this formulation the physical operators in the constrainted Hilbert space are invariant under local unitary transformations mixing boson and fermion representations. To illustrate, the formulation is applied(More)
Traveling has always been a popular way of relaxation. With the ongoing stress cause by work and daily labours, the need of reducing stress via traveling has grown immensely, making trips a major part of human life. The core of vacation is to relax not only the body, but also the soul. However, there are so many information scattered around the internet,(More)
We present a review of the measurements of the CKM angle β (φ 1) by the BABAR and Belle experiments at the asymmetric-energy e + e − B Factories PEP-II and KEKB. The angle β (φ 1) is measured by time-dependent CP analyses of neutral B meson decays in a Υ (4S) → BB system, where one B meson is fully reconstructed in a final state that can be accessed to by(More)
A supersymmetric way of imposing the constraint of no double occupancy in models with strong on-site Coulomb repulsion is presented in this paper. In this formulation the physical operators in the constrainted Hilbert space are invariant under local unitary transformations mixing boson and fermion representations. As an illustration the formulation is(More)
