A modification of the classical Simulated Annealing algorithm for the macro-cell placement problem is proposed for implementation on multiprocessor systems. The algorithm has been implemented on the Sequent Balance 8000, a multiprocessor system with a shared-memory architecture. Experimental results show that the new algorithm obtains results comparable in(More)
The objective of this paper was to assess the effects of switching from typical and/or atypical antipsychotics to ziprasidone, owing to inadequate response or intolerance, in chronic schizophrenic patients. A total of 312 patients were switched to an 8-week, open-label, flexible dose (40-160 mg/day) of ziprasidone. Psychiatric status was evaluated by(More)
New techniques for routing general multi-layer channels are introduced. These techniques can handle a variety of technology constraints. For example, linewidth and line-to-line spacing can be specified independently for each layer, and contact stacking can be allowed or forbidden. These techniques have been implemented in a new multi-layer channel router(More)
This 18-week, randomized, flexible-dose, double-blind, double-dummy trial evaluated ziprasidone as an alternative to clozapine in treatment-refractory schizophrenia patients. Patients had a DSM-IV diagnosis of schizophrenia, a history of resistance and/or intolerance to at least three acute cycles with different antipsychotics given at therapeutic doses,(More)
BACKGROUND Recent data have suggested few differences in the cognitive effects of antipsychotic medications. However, assessment of such effects can be complex, due to a number of factors. Clozapine has previously shown greater clinical and lesser cognitive benefits than other atypicals. This study compared the cognitive benefits of clozapine and(More)
The second-order azimuthal anisotropy Fourier harmonics, v2, are obtained in p-Pb and PbPb collisions over a wide pseudorapidity (η) range based on correlations among six or more charged particles. The p-Pb data, corresponding to an integrated luminosity of 35  nb-1, were collected during the 2013 LHC p-Pb run at a nucleon-nucleon center-of-mass energy of(More)
A study of vector boson scattering in pp collisions at a center-of-mass energy of 8 TeV is presented. The data sample corresponds to an integrated luminosity of 19.4  fb(-1) collected with the CMS detector. Candidate events are selected with exactly two leptons of the same charge, two jets with large rapidity separation and high dijet mass, and moderate(More)
Measurements of the differential and double-differential Drell–Yan cross sections in the dielectron and dimuon channels are presented. They are based on proton– proton collision data at √ s = 8 TeV recorded with the CMS detector at the LHC and corresponding to an integrated luminosity of 19.7 fb −1. The measured inclusive cross section in the Z peak region(More)
