Long Coherence Times At 300 K For Nitrogen-Vacancy Center Spins In Diamond Grown By Chemical Vapor Deposition, John S. Colton, T. A. Kennedy, J. E. Butler, R. C. Linares, P.J. Doering

Faculty Publications

Electron-spin-echo experiments reveal phase-memory times as long as 58 μs at 300 K for nitrogen-vacancy centers in chemical vapor deposition (CVD) single crystals. The spins were optically polarized and optically detected. Two high-quality CVD samples were studied. From the current results, it is not clear whether these phase-memory times represent a fundamental limit or are limited by an external source of decoherence.

Intercontinental Transport Of Pollution Manifested In The Variability And Seasonal Trend Of Springtime O3 At Northern Middle And High Latitudes, Yuhang Wang, Changsub Shim, Nicola J. Blake, D R. Blake, Yunsoo Choi, Brian Ridley, Jack E. Dibb, Anthony Wimmers, Jennie Moody, F Flocke, Andrew Weinheimer, R. Talbot, Elliot Atlas

Earth Sciences

Observations (0–8 km) from the Tropospheric Ozone Production about the Spring Equinox (TOPSE) experiment are analyzed to examine air masses contributing to the observed variability of springtime O₃ and its seasonal increase at 40°–85°N over North America. Factor analysis using the positive matrix factorization and principal component analysis methods is applied to the data set with 14 chemical tracers (O₃, NO_y, PAN, CO, CH₄, C₂H₂, C₃H₈, CH₃Cl, CH₃Br, C₂Cl₄, CFC-11, HCFC-141B, Halon-1211, and ⁷Be) and one …

Uptake Of Nitrate And Sulfate On Dust Aerosols During Trace-P, C. Jordan, Jack E. Dibb, B E. Anderson, H Fuelberg

Earth Sciences

Aerosol data collected near Asia on the DC-8 aircraft platform during TRACE-P has been examined for evidence of uptake of NO₃⁻ and SO₄⁼ on dust surfaces. Data is compared between a sector where dust was predominant and a sector where dust was less of an influence. Coincident with dust were higher mixing ratios of anthropogenic pollutants. HNO₃, SO₂, and CO were higher in the dust sector than the nondust sector by factors of 2.7, 6.2, and 1.5, respectively. The colocation of dust and pollution sources allowed for the uptake of NO_{3 …}

Chemical And Physical Properties Of Bulk Aerosols Within Four Sectors Observed During Trace-P, C. Jordan, B E. Anderson, R. Talbot, Jack E. Dibb, H Fuelberg, Charlie Hudgins, C M. Kiley, R. S. Russo, Eric Scheuer, Garry Seid, K L. Thornhill, E L. Winstead

Earth Sciences

Chemical and physical aerosol data collected on the DC-8 during TRACE-P were grouped into four sectors based on back trajectories. The four sectors represent long-range transport from the west (WSW), regional circulation over the western Pacific and Southeast Asia (SE Asia), polluted transport from northern Asia with substantial sea salt at low altitudes (NNW) and a substantial amount of dust (Channel). WSW has generally low mixing ratios at both middle and high altitudes, with the bulk of the aerosol mass due to non-sea-salt water-soluble inorganic species. Low altitude SE Asia also has low mean mixing ratios in general, with the …

Aerosol Chemical Composition In Asian Continental Outflow During The Trace-P Campaign: Comparison With Pem-West B, Jack E. Dibb, R. Talbot, Eric Scheuer, Garry Seid, Melody A. Avery, H B. Singh

Earth Sciences

Aerosol associated soluble ions and the radionuclide tracers ⁷Be and ²¹⁰Pb were quantified in 414 filter samples collected in spring 2001 from the DC-8 during the Transport and Chemical Evolution over the Pacific (TRACE-P) campaign. Binning the data into near Asia (flights from Hong Kong and Japan) and remote Pacific (all other flights) revealed large enhancements of NO₃⁻, SO₄⁼, C₂O₄⁼, NH₄⁺, K⁺, Mg²⁺, and Ca²⁺ near Asia. The boundary layer and lower troposphere were most strongly influenced by continental …

Structural Order And Disorder In Co-Based Layered Cuprates Cosr2(Y,Ce)Scu2o5+2s (S=1-3), T. Nagai, V. P.S. Awana, E. Takayama-Muromachi, A. Yamazaki, M. Karppinen, H. Yamauchi, S. K. Malik, William B. Yelon, Y. Matsui

Physics Faculty Research & Creative Works

Crystal structures of a homologous series of Co-Based layered cuprates, CoSr₂(Y,Ce)_sCu₂O_5+2s (s=1-3), have been investigated by high-resolution electron microscopy (HREM) and electron diffraction (ED) techniques. for all the three phases ED patterns showed double periodicity along a direction parallel to the CoO layers, indicating a regular alternation of two types of CoO_4- tetrahedra chains within the layers. Also seen was ordering of the chains along the layer-stacking direction for the s=1 phase (Co-1212); ED patterns simulated based on the proposed superstructure model well reproduced the observed patterns. for the s=2 (Co-1222) and …

On The Complexity Of Implementing Certain Classes Of Shared Objects, King Yang Tan

Dartmouth College Ph.D Dissertations

We consider shared memory systems in which asynchronous processes cooperate with each other by communicating via shared data objects, such as counters, queues, stacks, and priority queues. The common approach to implementing such shared objects is based on locking: To perform an operation on a shared object, a process obtains a lock, accesses the object, and then releases the lock. Locking, however, has several drawbacks, including convoying, priority inversion, and deadlocks. Furthermore, lock-based implementations are not fault-tolerant: if a process crashes while holding a lock, other processes can end up waiting forever for the lock.

Wait-free linearizable implementations were conceived …

Low-Cost Data Acquisition Card For School-Network Cosmic Ray Detectors, Sten Hansen, Thomas Jordan, Daniel R. Claes, Gregory R. Snow, Hans Berns, T. H. Burnett, Richard Gran, R. Jeffrey Wilkes

Gregory Snow Publications

The Cosmic Ray Observatory Project (CROP) at University of Nebraska/Lincoln and the Washington Area Large-scale Time coincidence Array (WALTA) at University of Washington/Seattle are among several outreach projects siting cosmic-ray detectors at local high schools in cities around North America, to study the origins and interactions of highenergy cosmic rays. In a collaboration between QuarkNet, the outreach program based at Fermilab, CROP, and WALTA, a low-cost data acquisition electronics card has been developed to collect and synchronize the data from each detector site. The cost for each card is under US$500 for parts, functionally replacing much more expensive electronics crates …

Labview Interface For School-Network Daq Card, Hans Berns, T. H. Burnett, Richard Gran, Graham Wheel, R. Jeffrey Wilkes, Daniel R. Claes, Jared Kite, Gregory R. Snow

Gregory Snow Publications

A low-cost DAQ card has been developed for school-network cosmic ray detector projects, providing digitized data from photomultiplier tubes via a standard serial interface. To facilitate analysis of these data and to provide students with a starting point for custom readout systems, a model interface has been developed using the National Instruments LabVIEW(R) system. This user-friendly interface allows one to initialize the trigger coincidence conditions for data-taking runs and to monitor incoming or pre-recorded data sets with updating singles- and coincidence-rate plots and other user-selectable histograms.

Self-Interference Handling In Ofdm Based Wireless Communication Systems, Tevfik Yücek

USF Tampa Graduate Theses and Dissertations

Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier modulation scheme that provides efficient bandwidth utilization and robustness against time dispersive channels. This thesis deals with self-interference, or the corruption of desired signal by itself, in OFDM systems. Inter-symbol Interference (ISI) and Inter-carrier Interference (ICI) are two types of self-interference in OFDM systems. Cyclic prefix is one method to prevent the ISI which is the interference of the echoes of a transmitted signal with the original transmitted signal. The length of cyclic prefix required to remove ISI depends on the channel conditions, and usually it is chosen according to the worst …

Vibrofluidized Bed Drying Of Citrus Processing Residue For Byproduct Recovery, Eric A. Roe

USF Tampa Graduate Theses and Dissertations

Approximately 44% of the citrus that is processed becomes processing residue. The residue consists of the non-juice components of a citrus fruit, primarily peel and pulp, and is recovered by conversion to animal feed. The material is hygroscopic, agglomerating, has a wide particle size distribution, and must be carefully dried to avoid thermal damage to nutrients and flavors. This dissertation evaluates the possibility of utilizing a vibrofluidized bed dryer for citrus processing residue. Results demonstrate that it is possible to overcome the agglomeration difficulties associated with this material, offering an economically viable alternative processing methodology.

To properly analyze this proposed …

A Corrected Pseudo-Score Approach For Additive Hazards Model With Longitudinal Covariates Measured With Error, Xiao Song, Yijian Huang

UW Biostatistics Working Paper Series

In medical studies, it is often of interest to characterize the relationship between a time-to-event and covariates, not only time-independent but also time-dependent. Time-dependent covariates are generally measured intermittently and with error. Recent interests focus on the proportional hazards framework, with longitudinal data jointly modeled through a mixed effects model. However, approaches under this framework depend on the normality assumption of the error, and might encounter intractable numerical difficulties in practice. This motivates us to consider an alternative framework, that is, the additive hazards model, under which little has been done when time-dependent covariates are measured with error. We propose …

Agenda: Workshop On Directional Drilling In The Rocky Mountain Region, University Of Colorado Boulder. Natural Resources Law Center, Colorado School Of Mines

Workshop on Directional Drilling in the Rocky Mountain Region (November 13)

The Rocky Mountain region is seeing a large increase in the amount of exploration and production of oil and gas resources. Many people are interested in the use of directional and horizontal drilling technology but not much is understood about these technologies outside of the oil and gas industry. Many hold out the promise that directional drilling can minimize environmental impacts and the footprint of development. The technological, environmental, legal and policy implications of directional drilling for oil and gas in the Rocky Mountain region are the focus of this workshop.
