The DO Collaboration reports on a search for the standard model top quark in pp collisions at +s = 1.8 TeV at the Fermilab Tevatron with an integrated luminosity of approximately 50 pb '. We have searched for tt production in the dilepton and single-lepton decay channels with and without tagging of b-quark jets. We observed 17 events with an expected(More)
The Tandem NonStop System is a fault-tolerant [1], expandable, and distributed computer system designed expressly for online transaction processing. This paper describes the key primitives of the kernel of the operating system. The first section describes the basic hardware building blocks and introduces their software analogs: processes and messages. Using(More)
T he advent of fast, power-thrifty microprocessors has made possible pocket-size computers with performance approaching that of desktop PCs. This new class of mobile computers enables applications and user-interface modalities not feasible with traditional personal digital assistants and cell phones, while placing new demands on batteries and power(More)
is part of Compaq's Corporate Research group. Our focus is research on information technology that is relevant to the technical strategy of the Corporation and has the potential to open new business opportunities. Research at WRL ranges from Web search engines to tools to optimize binary codes, from hardware and software mechanisms to support scalable(More)
We search for the technicolor process pp-->rhoT/omegaT-->WpiT in events containing one electron and two jets, in data corresponding to an integrated luminosity of 390 pb(-1), recorded by the D0 experiment at the Fermilab Tevatron. Technicolor predicts that technipions pi(T) decay dominantly into bb, bc, or bc, depending on their charge. In these events b(More)
