Cation Site Occupancy and Defect Engineering in Perovskite Heterostructures
… in an antiferromagnet LuFeO₃ through cation antisite defects and concomitant inversion symmetry breaking. We elucidate how the crystal structure and ferroelectricity depend on cation stoichiometry. We then integrate this antiferromagnet into a self-assembled nanocomposite with a ferrimagnet …

GLYCOPEPTIDE ANALYSIS OF HIV-1 ENVELOPE PROTEIN USING HPLC/ESI-FTICR MS AND MALDI-TOF MS WITH ASIALOFETUIN ENRICHMENT AND SEPARATION TECHNIQUES
… can affect various biological functions. The site occupancy of the glycans as well as their various glycoforms makes glycans unique to analyze due to the fact that the variation in structure is not based on a genomic code. Glycosylation is a post-translational modification that provides …

Habitat, distribution, and diet of the Tennessee Bottlebrush Crayfish (Barbicambarus simmonsi)
… were to determine distribution, habitat use, and site occupancy of the Tennessee Bottlebrush Crayfish, Barbicambarus simmonsi. The distribution was increased from 3 to 14 sites across Shoal Creek. Habitat use modeling did not yield significant results, but observations indicate large flat boulders …

Bat occupancy of forests and managed savanna and woodland in the Missouri Ozark Region
… of detection (p), and 2) determine how site occupancy (Ψ) varies among savannas, woodlands, and forests as a function of vegetation structure and management history for 5 common bat species in the Missouri Ozark region: big brown bat (Eptesicus fuscus), eastern red bat (Lasiurus …

Transcription Factor Binding Dynamics and Spatial Co-localization In Human Genome
… been studied extensively in relation to binding site affinity and chromosome modifications; however, the relationship between genome spatial organisation and transcription factor binding is not well studied. Using the recently available high resolution Hi-C contact map of human GM12878 …

Cell parameter systematics of the binary silicate olivines: methods for the determination of composition and intracrystalline cation ordering
… regression results, most likely due to ambiguous site assignments. Because for both systems the a cell edge is mainly dependent on rM1 and b on rM2, these equations may be used to construct a vs. b diagrams which may be contoured for bulk composition, M2 site occupancy, and the distribution …

Occupancy and Detection Rates of Salamanders in Association with Altered Water Regimes at Mingo National Wildlife Refuge in Southeastern Missouri
… of reptiles, fish, and invertebrates at each site. I then generated models that would estimate site occupancy and detection rates for three common salamander species. For both Siren and Notophthalmus, occupancy and detection rates were higher at artificial wetlands than at more ephemeral …

Assessment of mudpuppy (Necturus maculosus) presence along the St. Clair-Detroit River System using environmental DNA and occupancy modeling
… success. Environmental DNA (eDNA) and occupancy modeling were used to determine best detection practices for this cryptic species. Mudpuppy eDNA was detected at all known mudpuppy sites with the addition of one site. Occupancy was highest at shoreline restoration sites, while reef …

Habitat Characteristics Affecting Site Occupation in Wintering Henslow’s Sparrows at Mississippi Sandhill Crane National Wildlife Refuge
… henslowii) </em>winters in recently burned sites in pine savannas of the Southeastern United States. Previous studies have suggested that factors such as seed abundance and litter depth are important to wintering Henslow’s sparrows. My study asked how habitat variables including vegetation …

The role of N-linked glycosylation on the structure and function of somatic angiotensin-converting enzyme
… crystallization. Previously, the N-glycan site occupancy required for the expression and stability of the individual domains of ACE was determined using minimally glycosylated (MG) N- and C-domain isoforms. However the role of glycosylation in the structure and function of the full-length …

Habitat Niche Modeling in the Texas Horned Lizard (Phrynosoma cornutum): Applications to Planned Translocation
… datasets used to quantify interaction between site occupancy and habitat model predictions. Lizard paths were tested against random walk models to determine efficiency of travel, and site occupancy metrics (powder track and telemetry Mahalanobis distance values) were tested using parametric …

Anthropogenic environmental change and habitat occupancy by riparian muskrats in a Midwestern landscape
… species. I completed multiple surveys for occupancy by muskrats at 90 sites in central Illinois in 2007 and 2008. Sites were stratified based on urbanization levels. Occupancy was determined by presence of tracks, scat, and feeding sign in 200-m stream segments that approximated a …

Applicability of Using Physical Stability Data and Advanced Visualization Methods in Protein Comparability Studies
… in yeast, the effect of N-linked glycosylation site occupancy, as well as the effect of different charge states in various nonglycosylated forms, within the CH2 domain was examined. Using this approach, differences in conformational stability were detected under stress conditions that did not …
