Norms of products and factors polynomials
(2001-01-19)We study inequalities connecting a product of uniform norms of polynomials with the norm of their product. Generalizing Gel’fond-Mahler inequality for the unit disk and Kneser-Borwein inequality for the segment [−1,1], we ... -
North American Indigenous adolescent substance use
(Elsevier BV, 2013-05)Objectives: To investigate growth in problem drinking and monthly marijuana use among North American Indigenous adolescents from the upper Midwest and Canada. -
Novel analytical method, Birth Date Selection Mapping, detects response of the Angus (Bos taurus) genome to selection on complex traits
(BioMed Central, 2012-11-09)Background: Several methods have recently been developed to identify regions of the genome that have been exposed to strong selection. However, recent theoretical and empirical work suggests that polygenic models are ... -
Novel and nodulation-regulated microRNAs in soybean roots
(BioMed Central, 2008-04-10)Background: Small RNAs regulate a number of developmental processes in plants and animals. However, the role of small RNAs in legume-rhizobial symbiosis is largely unexplored. Symbiosis between legumes (e.g. soybean) and ... -
Novel approach to identify inhibitors of iron acquisition systems of Pseudomonas aeruginosa
(American Society for Microbiology, 2022-07-13)Pseudomonas aeruginosa is an opportunistic pathogen that has been declared by the World Health Organization as a “priority 1 critical pathogen” needing immediate new strategies for chemotherapy. During infection, P. ... -
Novel genomes and genome constitutions identified by GISH and 5S rDNA and knotted1 genomic sequences in the genus Setaria
(BioMed Central, 2013-04-11)Background: The Setaria genus is increasingly of interest to researchers, as its two species, S. viridis and S. italica, are being developed as models for understanding C4 photosynthesis and plant functional genomics. The ... -
Novel high-rank phylogenetic lineages within a sulfur spring (Zodletone Spring, Oklahoma), revealed using a combined pyrosequencing-Sanger approach
(American Society for Microbiology, 2012-04-15)The utilization of high-throughput sequencing technologies in 16S rRNA gene-based diversity surveys has indicated that within most ecosystems, a significant fraction of the community could not be assigned to known microbial ... -
Novel insights into the historical biogeography of the streak-breasted scimitar babbler complex (Aves: Timaliidae: Pomatorhinus ruficollis complex)
(Oxford University Press, 2015)The Streak-breasted Scimitar Babblers of the Pomatorhinus ruficollis species complex are found in most of the forested habitats across southern and eastern Asia. The diversification history of this group is obscured by ... -
Novel thermostable xylanase GH10 from Malbranchea pulchella expressed in Aspergillus nidulans with potential applications in biotechnology
(BioMed Central, 2014-07-29)Background: The search for novel thermostable xylanases for industrial use has intensified in recent years, and thermophilic fungi are a promising source of useful enzymes. The present work reports the heterologous expression ... -
Novel virulence gene of Pseudomonas syringae pv. tomato strain DC3000
(American Society for Microbiology, 2005-11)Previously, we conducted a mutant screen of Pseudomonas syringae pv. tomato strain DC3000 to identify genes that contribute to virulence on Arabidopsis thaliana plants. Here we describe the characterization of one mutant ... -
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 ... -
Null-homologous exotic surfaces in 4-manifolds
(2013-10-07)In this paper we exhibit infinite families of embedded tori in 4-manifolds that are topologically isotopic but smoothly distinct. The interesting thing about these tori is that they are topologically trivial in the sense ... -
Nutrients mediate intestinal bacteria-mucosal immune crosstalk
(Frontiers Media, 2018-01-24)The intestine is the shared site of nutrient digestion, microbiota colonization and immune cell location and this geographic proximity contributes to a large extent to their interaction. The onset and development of a great ... -
Observation of a Cole-Davidson type complex conductivity in the limit of very low carrier densities in doped silicon
(AIP Publishing, 1998-05-04)Using THz time-domain spectroscopy to measure the complex conductivity of doped silicon from low frequencies to frequencies higher than the THz plasma frequency and the carrier damping rate, we were able to show in the ... -
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 ... -
Observation of electromagnetic shock waves from propagating surface-dipole distributions
(American Physical Society, 1989-06-19)We have directly measured the time-dependent electromagnetic shock wave generated by an electric surface-dipole distribution propagating faster than the phase velocity in the underlying dielectric substrate. The results ... -
Observation of self-steepening of optical pulses with possible shock formation
(American Physical Society, 1973-08-13)Near-resonant light pulses were steepened by passage through Rb vapor. The rise time changed from typically 4 nsec to less than 1 nsec, and complicated envelopes developed. The self-steepening, well described by adiabatic ... -
Observation of the formation of an optical intensity shock and wave breaking in the nonlinear propagation of pulses in optical fibers
(American Physical Society, 1989-01-30)We have observed the formation of an optical intensity shock and the subsequent wave breaking in the nonlinear propagation of 1-psec pulses in an optical fiber. The wave breaking manifests itself as the appearance of ... -
Observation of the formation of the 0-pi pulse
(American Physical Society, 1984-08-06)We have measured with 0.5-psec resolution the reshaping of small-area 7-psec laser pulses to 0-pi pulses due to their passage through an optically thick sodium cell. The reshaped pulses have a picosecond oscillatory structure ... -
Observation of unitary p-wave interactions between fermions in an optical lattice
(2022-05-27)Exchange-antisymmetric pair wavefunctions in fermionic systems can give rise to unconventional superconductors and superfluids with non-trivial transport properties. The realisation of these states in controllable quantum ...
