NetiNeti : Discovery of Scientific Names from Text Using Machine Learning Methods Figure 3
A scientific name for an organism can be associated with almost all biological data. Name identification is an important step in many text mining tasks aiming to extract useful information from biological, biomedical and ...
Species compositional differences on different-aged glacial landscapes drive contrasting responses of tundra to nutrient addition
In the northern foothills of the Brooks Range, Alaska, moist non-acidic tundra dominates more recently deglaciated upland landscapes, whereas moist acidic tundra dominates older upland landscapes. In previous studies, ...
Nematostella vectensis BAC sequences
A key tool for investigating the regulation of genes is represented by Bacterial Artificial Chromosomes-reporter constructs (BAC). BACs are large insert libraries, often >>100 kb, which thus capture the genomic sequences ...
Nematostella Embryonic Transcriptome
RNA-Seq was performed on Nematostella Embryos at 5 timepoints during early development: 0hrs, 6hrs, 12hrs, 18hrs, 24hrs after fertilization. Embryos were harvested, lysed and mRNAs were selected using Dynabeads. Directional ...
Nematostella High-density RNAseq time-course
RNA-Seq was performed on Nematostella embryos at 20 timepoints: unfertilized eggs, 1hour post fertilization (hpf), 2hpf, 3hpf, 4hpf, 5hpf, 6hpf, 7hpf, 8hpf, 9hpf, 10hpf, 11hpf, 12hpf, 13hpf, 14hpf, 15hpf, 16hpf, 17hpf, ...
Pattern and variation of C:N:P ratios in China’s soils : a synthesis of observational data
Inspired by previous studies that have indicated consistent or even well-constrained relationships among carbon (C), nitrogen (N) and phosphorus (P) in soils, we have endeavored to explore general soil C:N:P ratios in ...
Nitrogen dynamics in a small arctic watershed: retention and downhill movement of 15N
We examined short- and long-term nitrogen (N) dynamics and availability along an arctic hillslope in Alaska, USA, using stable isotope of nitrogen (15N), as a tracer. Tracer levels of 15NH4+ were sprayed once onto the ...

Directly probing the mechanical properties of the spindle and its matrix
(Rockefeller University Press, 2010-02-22)
Several recent models for spindle length regulation propose an elastic pole to pole spindle matrix that is sufficiently strong to bear or antagonize forces generated by microtubules and microtubule motors. We tested this ...
Ancestry of motor innervation to pectoral fin and forelimb
(Nature Publishing Group, 2010-07-27)
Motor innervation to the tetrapod forelimb and fish pectoral fin is assumed to share a conserved spinal cord origin, despite major structural and functional innovations of the appendage during the vertebrate water-to-land ...
