Observation of a new type of THz resonance of surface plasmons propagating on metal-film hole arrays
(American Physical Society, 2004-11-04)
Highly conducting metal-film subwavelength hole arrays, lithographically fabricated on high-resistivity silicon wafers in optical contact with thick silicon plates, have been characterized by terahertz time-domain spectroscopy ...
Novelty and uniqueness patterns of rare members of the soil biosphere
(American Society for Microbiology, 2008-09)
Soil bacterial communities typically exhibit a distribution pattern in which most bacterial species are present in low abundance. Due to the relatively small size of most culture-independent sequencing surveys, a detailed ...
High porosity metallic glass foam: A powder metallurgy route
(AIP Publishing, 2007-10-15)
A powder metallurgy route to the fabrication of metallic glass foam is introduced. The method involves consolidating metallic glass powder blended with blowing agent particulates to produce expandable precursors, capable ...
Genomic comparison of plant pathogenic and nonpathogenic Serratia marcescens strains by suppressive subtractive hybridization
(American Society for Microbiology, 2005-12)
Cucurbit yellow vine disease (CYVD) is caused by disease-associated Serratia marcescens strains that have phenotypes significantly different from those of nonphytopathogenic strains. To identify the genetic differences ...
Catastrophic wildfire and number of populations as factors influencing risk of extinction for Gila trout (Oncorhynchus gilae)
(Monte L. Bean Life Science Museau, 2001-04)
We used the computer program RAMAS to explore the sensitivity of an extinction-risk model for the Gila trout (Oncorhynchus gilae) to management of wildfires and number of populations of the species. The Gila trout is an ...
Ultraslow light in inhomogeneously broadened media
(American Physical Society, 2006-04-19)
We calculate the characteristics of ultraslow light in an inhomogeneously broadened medium. We present analytical and numerical results for the group delay as a function of power of the propagating pulse. We apply these ...
Overlapping data problem
(Social Sciences Research Network, 2009)
Overlapping data are often used in finance and economics, but applied work often uses inefficient estimators. The article evaluates possible reasons for using overlapping data and provides a guide about which estimator to ...
Fall forage biomass and nitrogen composition of winter wheat populations selected from grain-only and dual-purpose environments
(Crop Science Society of America, 2005-01)
Winter wheat (Triticum aestivum L.) is the foundation of many agricultural enterprises in the southern Great Plains and is grown primarily as either a grain-only (GO) or a dual-purpose (DP, grazing plus grain) crop. ...
Genetic diversity among Arthrobacter species collected across a heterogeneous series of terrestrial deep-subsurface sediments as determined on the basis of 16S rRNA and recA gene sequences
(American Society for Microbiology, 2000-08)
This study was undertaken in an effort to understand how the population structure of bacteria within terrestrial deep-subsurface environments correlates with the physical and chemical structure of their environment. ...
Proteomic analysis of lamellar bodies isolated from rat lungs
(BioMed Central, 2008-06-24)
Background: Lamellar bodies are lysosome-related secretory granules and store lung surfactant in alveolar type II cells. To better understand the mechanisms of surfactant secretion, we carried out proteomic analyses of ...
