An Improved Algorithm to Delineate Urban Targets with Model-Based Decomposition of PolSAR Data
(2017-10-11)
In model-based decomposition algorithms using polarimetric synthetic aperture radar (PolSAR) data, urban targets are typically identified based on the existence of strong double-bounced scattering. However, urban targets ...
Anaerobic utilization of Fe(III)-xenosiderophores among Bacteroides species and the distinct assimilation of Fe(III)- ferrichrome by Bacteroides fragilis within the genus
(2017-08)
In this study, we show that Bacteroides species utilize Fe(III)-xenosiderophores as the only source of exogenous iron to support growth under iron-limiting conditions in vitro anaerobically. Bacteroides fragilis was the ...
Resolving power of diffraction imaging with an objective: a numerical study
(2017-05)
Diffraction imaging in the far-field can detect 3D morphological features of an object for its coherent nature. We describe methods for accurate calculation and analysis of diffraction images of scatterers of single and ...
Health effects following subacute exposure to geogenic dust collected from active drainage surfaces (Nellis Dunes Recreation Area, Las Vegas, NV)
(2017-12-08)
The specific health effects of directinhalation of fine minerogenic dusts generated by natural soil surfaces
remain poorly known and relatively little researched. To learn more about this exposure and its contribution
to ...
A 14-year longitudinal study of the impact of clean indoor air legislation on state smoking prevalence, USA, 1997-2010
(2017)
While clean indoor air legislation at the state level is an evidence-based recommendation, only limited evidence exists regarding the impact of clean indoor air policies on state smoking prevalence. Using state smoking ...
The effects of elevated temperature and dissolved ρCO2 on a marine foundation species
(2017-04)
Understanding how climate change and other environmental stressors will affect species is a fundamental concern of modern ecology. Indeed, numerous studies have documented how climate stressors affect species distributions ...
A possible dose–response association between distance to farmers’ markets and roadside produce stands, frequency of shopping, fruit and vegetable consumption, and body mass index among customers in the Southern United States
(2017-01)
Background: The association between farmers’ market characteristics and consumer shopping habits remains
unclear. Our objective was to examine associations among distance to farmers’ markets, amenities within farmers’
markets, ...
BARRIERS TO SUSTAINABILITY: A CROSS-CASE ANALYSIS OF SMALL TOURISM ACCOMMODATION ENTERPRISES (STAEs) IN DARE COUNTY, NORTH CAROLINA
(East Carolina University, 2017-07-05)
Small tourism accommodation enterprises (STAEs) are a continually growing segment of the hospitality industry, with considerable influence on the adoption of sustainability. Incorporating sustainability can present challenges, ...
The effects of an afterschool STEM program on students’ motivation and engagement
(2017-06-12)
Background: One significant factor in facilitating students’ career intentions and persistence in STEM (science, technology, engineering, and mathematics) fields is targeting their interests and motivation before eighth ...
A high-efficiency CRISPR/Cas9 system for targeted mutagenesis in Cotton (Gossypium hirsutum L.)
(2017-03-03)
The complex allotetraploid genome is one of major challenges in cotton for repressing gene expression.
Developing site-specific DNA mutation is the long-term dream for cotton breeding scientists. The
clustered regularly ...
