Fractional Brownian fields over manifolds

Creator:: Gelbaum, Zachary A.
Abstract:: Extensions of the fractional Brownian fields are constructed over a complete Riemannian manifold. This construction is carried out for the full range of the Hurst parameter α ∈ (0, 1). In particular, we establish existence, distributional scaling (self-similiarity), stationarity of the increments, and almost sure H¨older continuity of sample paths....

Experimental thermodynamic first and second law analysis of a variable output 1-4.5 kWe, ICE-driven, natural-gas fueled micro-CHP generator

Creator:: Taie, Zachary and Hagen, Christopher
Abstract:: This work experimentally assesses the thermodynamic performance of the only single kWe, variable-output continuous duty, internal combustion engine driven, residential micro-combined heat and power (mCHP generator (Marathon Engine Systems ecopower) available in the United States. The system underwent steady state testing over its full operating range, and first (energy) and...

Effects of Ambient Turbulence on Interleaving at a Baroclinic Front

Creator:: Smyth, William D. and Ruddick, Barry
Abstract:: In this paper the authors investigate the action of ambient turbulence on thermohaline interleaving using both theory and numerical calculations in combination with observations from Meddy Sharon and the Faroe Front. The highly simplified models of ambient turbulence used previously are improved upon by allowing turbulent diffusivities of momentum, heat,...

DAPI direct counting underestimates bacterial abundances and average cell size compared to AO direct counting

Creator:: Suzuki, Marcelino T., Sherr, Evelyn, and Sherr, Barry F.
Abstract:: We compared estimates of bacterial abundance and of average bacterial cell size based on direct counts of bacterioplankton cells stained with acridine orange (AO) or 4’-6-diamidino-2-phenylidole (DAPI). Estimates of numbers mll–1 of bacteria stained with DAPI were on average 70% (range 57–82%) of bacterial counts made with AO as the...

Activity of marine bacteria under incubated and in situ conditions

Creator:: Sherr, Evelyn, Sherr, Barry F., and Sigmon, Crystal T.
Abstract:: We evaluated the extent to which the average metabolic activity of open ocean bacterioplankton changed during 2 to 3 d incubations of 1 μm filtered seawater at in situ temperature. Indices of bacterial activity during incubation experiments were compared to those of in situ bacterioplankton, which were repeatedly sampled at...

Activity and phylogenetic diversity of bacterial cells with high and low nucleic acid content and electron transport system activity in an upwelling ecosystem

Creator:: Longnecker, K., Sherr, Barry F., and Sherr, Evelyn
Abstract:: We evaluated whether bacteria with higher cell-specific nucleic acid content (HNA) or an active electron transport system, i.e., positive for reduction of 5-cyano-2,3-ditolyl tetrazolium chloride (CTC), were responsible for the bulk of bacterioplankton metabolic activity. We also examined whether the phylogenetic diversity of HNA and CTC-positive cells differed from the...

The Relationship between Winds, Surface Roughness, and Radar Backscatter at Low Incidence Angles from TRMM Precipitation Radar Measurements

Creator:: Freilich, Michael H. and Vanhoff, Barry A.
Abstract:: One year of collocated, rain-free normalized backscatter cross-section measurements from the Tropical Rainfall Mapping Mission (TRMM) precipitation radar (PR) and wind speed estimates from the TRMM Microwave Imager are used to construct fully empirical model functions relating cross section to wind speed for incidence angles from 0° (nadir) to 18°....

Effect of protistan grazing on the frequency of dividing cells in bacterioplankton asemblages

Creator:: Sherr, Barry F., Sherr, Evelyn, and McDaniel, Julie
Abstract:: Grazing by phagotrophic flagellates and ciliates is a major source of mortality for bacterioplankton in both marine and freshwater systems. Recent studies have demonstrated a positive relationship between clearance rate and prey size for bacterivorous protists. We tested the idea that, by selectively grazing the larger (more actively growing or...

Aerosol particles collected on aircraft flights over the northwestern Pacific region during the ACE-Asia campaign: Composition and major sources of the organic compounds

Creator:: Simoneit, Bernd R. T., Kobayashi, Minoru, Mochida, Michihiro, Kawamura, Kimitaka, and Huebert, Barry J.
Abstract:: Atmospheric particulate matter, collected over the polluted east Asia/Pacific region in spring 2001 during research flights with the National Center for Atmospheric Research (NCAR) C-130 aircraft, was analyzed for different types of organic compounds using capillary gas chromatography–mass spectrometry. More than 70 organic species were detected in the aerosols and...
