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....

Nesting pair density and abundance of ferruginous hawks (Buteo regalis) and golden eagles (Aquila chrysaetos) from aerial surveys in Wyoming

Creator:: Olson, Lucretia E., Oakleaf, Robert J., Squires, John R., Wallace, Zachary P., and Kennedy, Patricia L.
Abstract:: Raptors that inhabit sagebrush steppe and grassland ecosystems in the western United States may be threatened by continued loss and modification of their habitat due to energy development, conversion to agriculture, and human encroachment. Actions to protect these species are hampered by a lack of reliable data on such basic...

Human-made structures, vegetation, and weather influence ferruginous hawk breeding performance

Creator:: Wallace, Zachary P., Kennedy, Patricia L., Squires, John R., Olson, Lucretia E., and Oakleaf, Robert J.
Abstract:: Studies of anthropogenic impacts on wildlife may produce inconclusive or biased results if they fail to account for natural sources of variation in breeding performance and do not use probabilistic sampling at a scale functional for management. We used stratified random sampling and generalized linear mixed models to test hypotheses...

Gelling properties of surimi as affected by the particle size of fish bone

Creator:: Yin, Tao, Reed, Zachary H., and Park, Jae W.
Abstract:: The effects of fish bone with two different particle sizes (micro and nano) on Alaska pollock surimi gels prepared by two heating procedures were investigated. Heating procedures (with or without setting) resulted in significantly different gel texture values. Nano-scaled fish bone (NFB) effectively increased gel breaking force and penetration distance...

Streamlining and Core Genome Conservation among Highly Divergent Members of the SAR11 Clade

Creator:: Grote, Jana, Thrash, J. Cameron, Huggett, Megan J., Landry, Zachary C., Carini, Paul, Giovannoni, Stephen J., and Rappe, Michael S.
Abstract:: SAR11 is an ancient and diverse clade of heterotrophic bacteria that are abundant throughout the world's oceans, where they play a major role in the ocean carbon cycle. Correlations between the phylogenetic branching order and spatiotemporal patterns in cell distributions from planktonic ocean environments indicate that SAR11 has evolved into...

Re-Occupancy of Breeding Territories by Ferruginous Hawks in Wyoming: Relationships to Environmental and Anthropogenic Factors

Creator:: Wallace, Zachary P., Kennedy, Patricia L., Squires, John R., Oakleaf, Robert J., Olson, Lucretia E., and Dugger, Katie M.
Abstract:: Grassland and shrubland birds are declining globally due in part to anthropogenic habitat modification. Because population performance of these species is also influenced by non-anthropogenic factors, it is important to incorporate all relevant ecological drivers into demographic models. We used design-based sampling and occupancy models to test relationships of environmental...

Terahertz induced transparency in single-layer graphene

Creator:: Paul, Michael J., Lee, Byounghwak, Wardini, Jenna L., Thompson, Zachary J., Stickel, Andrew D., Mousavian, Ali, Choi, Hyunyong, Minot, Ethan D., and Lee, Yun-Shik
Abstract:: We show that the transmission of a terahertz (THz) pulse through single-layer graphene is strongly nonlinear. As the peak electric field of the THz pulse exceeds 50 kV/cm, the graphene becomes increasingly transparent to the THz radiation. When field strength reaches 800 kV/cm, the increased transparency corresponds to a two-fold...

Single-cell enabled comparative genomics of a deep ocean SAR11 bathytype

Creator:: Thrash, J. Cameron, Temperton, Ben, Swan, Brandon K., Landry, Zachary C., Woyke, Tanja, DoLong, Edward F., Stepanauskas, Ramunas, and Giovannoni, Stephan J.
Abstract:: Bacterioplankton of the SAR11 clade are the most abundant microorganisms in marine systems, usually representing 25% or more of the total bacterial cells in seawater worldwide. SAR11 is divided into subclades with distinct spatiotemporal distributions (ecotypes), some of which appear to be specific to deep water. Here we examine the...

Anisotropic high-field terahertz response of free-standing carbon nanotubes

Creator:: Lee, Byounghwak, Mousavian, Ali, Paul, Michael J., Thompson, Zachary J., Stickel, Andrew D., McCuen, Dalton R., Jang, Eui Yun, Kim, Yong Hyup, Kyoung, Jisoo, Kim, Dai-Sik, and Lee, Yun-Shik
Abstract:: We demonstrate that unidirectionally aligned, free-standing multi-walled carbon nanotubes (CNTs) exhibit highly anisotropic linear and nonlinear terahertz (THz) responses. For the polarization parallel to the CNT axis, strong THz pulses induce nonlinear absorption in the quasi-one-dimensional conducting media, while no nonlinear effect is observed in the perpendicular polarization configuration. Time-resolved...

Mycobacterium avium Possesses Extracellular DNA that Contributes to Biofilm Formation, Structural Integrity, and Tolerance to Antibiotics

Creator:: Rose, Sasha J., Babrak, Lmar M., and Bermudez, Luiz E.
Abstract:: Mycobacterium avium subsp. hominissuis is an opportunistic pathogen that is associated with biofilm-related infections of the respiratory tract and is difficult to treat. In recent years, extracellular DNA (eDNA) has been found to be a major component of bacterial biofilms, including many pathogens involved in biofilm-associated infections. To date, eDNA...
