The D0 experiment, located at the Fermilab National Accelerator Laboratory in the US, is used to study proton-anti-proton collisions at a center of mass energy of 1.96 TeV. The experiment's data acquisition system is based on a sophisticated trigger system used to select potentially interesting events. The Level 2 Silicon Track Trigger (L2STT) is part of the trigger system that provides precise reconstruction of charged particle tracks allowing the selection of events that contain the decays of long lived particles. For example, such particles appear in the decay of the Higgs boson into a pair of bottom quarks. The design of the L2STT preprocessor has greatly benefited from recent advances in electronics technology. The preprocessor has been recently installed and will be used to further optimize the triggering strategy of the experiment. Leptoquarks would mediate hypothetical new interactions between the quarks and leptons of the Standard Model. The existence of such particles would be evidence for physics beyond that model. In this thesis, a direct search for leptoquarks is performed in the jets and missing transverse energy final state. For this analysis, a trigger had to be developed along with a tool to precisely determine its efficiency. An analysis of …

Ensemble concert performed at UNT College of Music Recital Hall.

Recording of Paolo Besagno's Normalmente, due. This work is an homage to Mr. Jacquard and his loom. The score was written with rows and columns in order to maintain the concept of the loom. The composer describes this piece as "a word game".

Recording of Marco Dibeltulu's Microclima II. This work was created as part of the open work "Les Maîtres Sonneurs" for the Synthèse festival. The intent of this work was to combine electroacoustic music with popular music. The title metaphorically represents the island in the center of the Mediterranean and the sound mimics the harsh and wild landscapes of the island with the emerald sea and ancestral music. This has been represented by the Launeddas and by the Canto a Tenore, a typical expression of island vocal polyphony.

Annual journal containing essays, studies, book reviews, and other articles related to the history of Western Music Theory, methods of analysis, and analytical discussions of musical compositions. The appendix includes corrigenda from the preceding volume, information about contributors to the current volume, and an index of content in previously-issued volumes.

Recording of Stefano Trevisi's Tabula irrasa. This is a work for tape that was inspired by the composer's experiences on trains crossing the Po Valley. While travelling, the composer found himself focusing on the landscape and drew inspiration from the fields, farmsteads, hedges, etc. The materials that have been used are based on the sounds of the language spoken by the river. The composer thanks Italo Formigoni and Wainer Melli for their helpfulness as well as the Istituto Mantovano di Storia Contemporanea for historical audio documents.
