INTRODUCTION Cone-beam computed tomography (CBCT) imaging has broadened opportunities for examining morphologic aspects of the craniofacial complex, including alveolar bone, but limitations of the technology have yet to be defined. Through the use of comparisons with direct measurements, the purpose of this study was to investigate the accuracy and(More)
PURPOSE Cone-beam computed technology (CBCT) is a relatively new medium for maxillofacial conditions. Developed in 1998, commercial cone beam technology has been commonly used since 2000. CBCT offers less radiation than computed tomography (CT) in 3D image construction. With the meteoric rise in the number of dental implant surgeries, CBCT could become a(More)
Soils are predicted to exhibit significant feedback to global warming via the temperature response of greenhouse gas (GHG) production. However, the temperature response of hydromorphic wetland soils is complicated by confounding factors such as oxygen (O2 ), nitrate (NO3-) and soil carbon (C). We examined the effect of a temperature gradient (2-25 °C) on(More)

We present final measurements of the Z boson-lepton coupling asymmetry parameters A(e), A(mu), and A(tau) with the complete sample of polarized Z bosons collected by the SLD detector at the SLAC Linear Collider. From the left-right production and decay polar angle asymmetries in leptonic Z decays we measure A(e) = 0.1544+/-0.0060, A(mu) = 0.142+/-0.015, and(More)
We present final measurements of the Z boson-lepton coupling asymmetry parameters Ae, Aμ, and Aτ with the complete sample of polarized Z bosons collected by the SLD detector at the SLAC Linear Collider. From the left-right production and decay polar angle asymmetries in leptonic Z decays we measure Ae = 0:1544 0:0060, Aμ = 0:142 0:015, and Aτ = 0:136 0:015.(More)
We present the first study of rapidity gaps in ee annihilations, using Z decays collected by the SLD experiment at SLAC. Our measured rapidity gap spectra fall exponentially with increasing gap size over five decades, and we observe no anomalous class of events containing large gaps. This supports the interpretation of the large-gap events measured in pp(More)
The parity violation parameters A(b) and A(c) of the Zb(b) and Zc(c) couplings have been measured directly, using the polar angle dependence of the polarized cross sections at the Z(0) pole. Bottom and charmed hadrons were tagged via their semileptonic decays. Both the electron and muon analyses take advantage of new multivariate techniques to increase the(More)

Using an impact parameter tag to select an enriched sample of Z0 → bb events, we have measured the difference between the average charged multiplicity of Z0 → bb and Z0 → hadrons to be nb − nhad = 2.24 ± 0.30(stat.) ± 0.33(syst.) tracks per event. From this, we have derived nb − nuds = 3.31 ± 0.41 ± 0.79. Comparing this measurement with those at lower(More)
