[1] Here, I present a new absolute plate motion model of the Earth’s surface, determined from the alignment of present-day surface motions with 474 published shear wave (i.e., SKS) splitting orientations. When limited to oceanic islands and cratons, splitting orientations are assumed to reflect anisotropy in the asthenosphere caused by the differential motion between lithosphere and mesosphere....

In parallel systems it is possible for several processors to request concurrent access to a shared data structure such as a synchronization variable. Such an access pattern causes what is known as hotspot contention. In shared-memory multiprocessor systems that use a multistage interconnection network, hot-spot contention may result in "tree saturation" that degrades the system performance. It ...

In the context of protein-protein interactions, the term "hot spot" refers to a residue or cluster of residues that makes a major contribution to the binding free energy, as determined by alanine scanning mutagenesis. In contrast, in pharmaceutical research, a hot spot is a site on a target protein that has high propensity for ligand binding and hence is potentially important for drug discovery...

[1] Recent observations of ridge bathymetry suggest magmatic segmentation at fastand intermediatespreading centers is linked to the migration of the spreading axis over the mantle. At fastand intermediatespreading centers, Carbotte et al. (2004) observed that leading segments, those that are offset in the direction of ridge migration, are typically shallower (interpreted to be magmatically robu...

We propose the tracing of motion a shearing hot spot near Sgr A* source through dynamical image reconstruction algorithm, StarWarps. Such may form as exhaust magnetic reconnection in current sheet black hole horizon. A that is ejected from into an orbit accretion disk shear and diffuse due to instabilities at its boundary during orbit, resulting distinct signature. subdivide two different phase...

BACKGROUND Manual counting of microvessels is subjective and may lead to unacceptable interobserver variability, which may explain conflicting results. AIMS To develop and test an automated method for microvessel counting and objective selection of the hot spot, based on image processing of whole sections, and to compare this with manual selection of a hot spot and counting of microvessels. ...

IEEE 802.11 WLAN technology has become an inexpensive, yet powerful access technology that is targeted at mobile users that remain within reach of the hot-spot. Such hot-spots are usually provided by a wireless Internet service provider (WISP) in locations often frequented by travelers. Past measurements have shown that WLAN is even able to support mobile users passing by without stopping and “...

A composite transposon, Tn4731, associated with IS630 has been shown to transpose preferentially to 5'-TA-3' sequences that are located at two sites in a rho-dependent transcription terminator in plasmid ColE1 in Escherichia coli (T. Tenzen, S. Matsutani, and E. Ohtsubo, J. Bacteriol. 172:3830-3836, 1990). Here we demonstrated that Tn4731 preferentially transposes to TA sequences at four sites ...

Certain genomic loci, termed hot spots, are predisposed to undergo genetic recombination during meiosis at higher levels relative to the rest of the genome. The factors that specify hot-spot potential are not well understood. The M26 hot spot of Schizosaccharomyces pombe is dependent on certain trans activators and a specific nucleotide sequence, which can function as a hot spot in a position- ...
