a r t i c l e i n f o Keywords: mantle plume seismic tomography plume dynamics shear velocity Seismic detection of a mantle plume may resolve the debate about the origin of hotspots and the role of plumes in mantle convection. In this paper, we test the hypothesis that whole-mantle plumes exist below major hotspots, by quantitatively comparing physically plausible plume models with seismic imag...

Fog has often been identified as a crucial water source for plants in a variety of ecosystems world-wide, including a number of those identified as global biodiversity hotspots (Hamilton et al., 1995; Olson & Dinerstein, 1998). Biodiversity hotspots where fog is thought to play a particularly important role in species distributions include tropical montane cloud Geography Department, California...

UNLABELLED SpotXplore is a plugin for Cytoscape for extraction and visualization of differentially expressed subnetworks (hotspots) from gene networks. The hotspot-based visualization approach enables interactive exploration of regulatory interactions in differentially expressed gene sets, and it allows a researcher to explore gene expression in direct relation to the affected cellular gene net...

We study the formation of the electric and magnetic near-field hotspots in dielectric cylindrical dimers. We compare dielectric and metallic dimers by using experimental data for all materials and consider both TM and TE polarizations of light. We demonstrate that dielectric dimers allow us to simultaneously achieve pure magnetic and electric near-field hotspots for both polarizations in contra...

BACKGROUND In recent years, more than half of new HIV infections in the United States occur among African Americans in the Southeastern United States. Spatial epidemiological analyses can inform public health responses in the Deep South by identifying HIV hotspots and community-level factors associated with clustering. OBJECTIVE The goal of this study was to identify and characterize HIV clus...

To study the evolution of recombination rates in apes, we developed methodology to construct a fine-scale genetic map from high-throughput sequence data from 10 Western chimpanzees, Pan troglodytes verus. Compared to the human genetic map, broad-scale recombination rates tend to be conserved, but with exceptions, particularly in regions of chromosomal rearrangements and around the site of ances...

We have studied spatial Ca2+ distribution in hair cells filled with the low affinity fluorescent indicator Calcium Green 5N using real-time confocal microscopy and whole-cell recording. During depolarizations lasting several hundred milliseconds, Ca2+ fluorescence increased at a number of hotspots around the base of the cell but changed little near the hair bundle. The hotspots required influx ...

We present millimetre photometry and submillimetre imaging of the central core and two hotspots in the radio lobes of the galaxy Cygnus-A. For both hotspots and the central core the synchrotron spectrum continues smoothly from the radio to a frequency of 677GHz. The spectral index of the hotspots is constant over our frequency range, with a spectral index of α ≈ −1.0 (Sν ∝ ν α), which is steepe...

Recombination presents a nonuniform distribution across the genome. Genomic regions that present relatively higher frequencies of recombination are called hotspots while those with relatively lower frequencies of recombination are recombination coldspots. Therefore, the identification of hotspots/coldspots could provide useful information for the study of the mechanism of recombination. In this...
