Dance of the microbes:Bacteria living near coral reefs change in synchrony across distances（图）
microbes:Bacteria near coral reefs change synchrony across distances
2019/11/22
It might be called the dance of the microbes. It happens every day -- and night.Bacteria in waters above dozens of coral reefs change dramatically during the night, scientists have discovered, then re...
Travel Distances of Juvenile Fish Key to Better Conservation
Travel Distances Juvenile Fish Key Conservation
2017/7/20
Marine reserves—sections of the ocean where fishing is prohibited—promote coral reef sustainability by preventing overfishing and increasing fish abundance and diversity. But to be effective, they nee...
Effective Charger Transfer Distances in Mixed-Valence Transition Metal Complexes
Charger Transfer Distances Mixed-Valence Transition Metal Complexes
2016/5/23
Stark (electroabsorption) spectroscopy can provide quantitative information on the change in dipole moment and polarizability for an electronic transition. In the case of mixed-valence transitions, th...
Analysis of genetic polymorphism in six meat sheep breeds and genetic distances between them
sheep microsatellite DNA genetic polymorphism
2015/6/8
The genomes of 6 sheep populations (Dorset, Texel, Black-Suffolk, Tan sheep, Small-tailed Han sheep, Tan and Small-tailed Han hybrid sheep) were screened using 7 microsatellite DNA markers to estimate...
Analysis of Geographic and Pairwise Distances among Chinese Cashmere Goat Populations
Cashmere Goat Geographic Distance Pairwise Distance Genetic Diversity
2016/5/11
This study investigated the geographic and pairwise distances of nine Chinese local Cashmere goat populations through the analysis of 20 microsatellite DNA markers. Fluorescence PCR was used to identi...
Large Harnack inequalities, Kobayashi distances and holomorphic motions
Large Harnack inequalities Kobayashi distances holomorphic motions Complex Variables
2012/4/18
We prove some generalizations and analogies of Harnack inequalities for pluriharmonic, holomorphic and "almost holomorphic" functions. The results are applied to the proving of smoothness properties o...
Sets avoiding integral distances
excluded distances Euclidean Ramsey theory integral distances Erdos-type problems
2012/4/18
We study open point sets in Euclidean spaces $\mathbb{R}^d$ without a pair of points an integral distance apart. By a result of Furstenberg, Katznelson, and Weiss such sets must be of Lebesgue upper d...
Quaternary Constant-Composition Codes with Weight Four and Distances Five or Six
Quaternary Constant-Composition Codes Weight Four Distances Five or Six
2012/3/1
The sizes of optimal constant-composition codes of weight three have been determined by Chee, Ge and Ling with four cases in doubt. Group divisible codes played an important role in their construction...
Gamma ray burst distances and the timescape cosmology
Gamma ray burst distances timescape cosmology
2011/10/20
Gamma ray bursts can potentially be used as distance indicators, providing the possibility of extending the Hubble diagram to redshifts ~7. Here we follow the analysis of Schaefer (2007), with the aim...
A critical analysis of three near-infrared photometric methods of estimating distances to cataclysmic variables
Stars: novae cataclysmic variables Stars:distances parallaxes Stars:statistics
2011/10/13
A critical analysis of three methods of estimating distances to cataclysmic variables (CVs) is performed. These methods, by Ak et al., Beuermann, and Knigge, all use near-infrared (JHK or Ks) magnitud...
Redshift and distances in a ΛCDM cosmology with non-linear inhomogeneities
cosmology: theory, relativity, large-scale structure of Universe, super- novae: general
2011/10/13
In this paper we study the effects of inhomogeneities on light propagation in a flat {\Lambda}CDM background. To this end we use exact solutions of Einstein's equations (Meures & Bruni 2011) where, st...
Nearest Neighbor Distances on a Circle: Multidimensional Case
Multidimensional Case Mathematical Physics Dynamical Systems
2011/9/16
Abstract: We study the distances, called spacings, between pairs of neighboring energy levels for the quantum harmonic oscillator. Specifically, we consider all energy levels falling between E and E+1...
Improved distances to several Galactic OB associations
Improved distances several Galactic associations
2011/10/11
Based on uvbybeta photometry we study the structure of several Galactic star-forming fields. Lac OB1 is a compact association at 520+/-20 pc spatially correlated with a region of intense HII emission ...
Given some assumptions it is possible to derive the most general theory of gravity at large distances. The force law derived from this theory contains a Rindler term in addition to well-known contribu...
Distances and Riemannian metrics for multivariate spectral densities
Riemannian metrics multivariate spectral densities Optimization and Control
2011/8/26
Abstract: We first introduce a class of divergence measures between power spectral density matrices. These are derived by comparing the suitability of different models in the context of optimal predic...
