Excess volcanism and crustal swelling associated with hot spots are generally attributed to thermal plumes upwelling from the mantle. This concept has been tested in the portion of the Mid-Atlantic Ridge between 34 degrees and 45 degrees (Azores hot spot). Peridotite and basalt data indicate that the upper mantle in the hot spot has undergone a high degree of melting relative to the mantle else...

A common feature of mapped crime patterns is a strong spatial and temporal clustering into crime “hot spots”. In this paper we explore a social interaction model for the evolution of the attractiveness of the crime environment for criminal activity. We see how hot spots may arise when the idiosyncratic attractiveness of the environment is not encouraging for criminal activity. The stability of ...

We propose an eecient dynamic load balancing scheme in cellular networks for managing tele-traac hot spot in which channel demand exceed a certain threshold. A hot spot, depicted as a stack of hexagonaìRings' of cells, is classiied as complete if all cells within it are hot. The rings containing only cold cells outside the hot spot are called`Peripheral Rings'. Our load balancing scheme migrate...

Crystallization ages of volcanic rocks, dredged or drilled from the Walvis Ridge (ten sites) and the Rio Grande Rise (one site), have been determined by the 40Ar/39Ar incremental heating technique. The fundamentally age-progressive distribution of these basement ages suggests a common hot spot source for volcanism on the island of Tristan da Cunha, along the Walvis Ridge and Rio Grande Rise, an...

(continued over page) Wouldn’t it be great if everyone had access to a seamless flow of information via the internet. Whether you worked in a metropolitan area or a remote farming region, the software or data needed to keep your business running efficiently could be downloaded quickly and affordably. Although this scenario already exists in some parts of the world, it remains wishful thinking f...

This paper proposes a voltage-based hot-spot detection method for photovoltaic (PV) string using the projector. Hot-spots form in solar cells at defects causing a high carrier recombination rate, it appears as a high reverse leakage current of p-n junctions when solar cells are partially shadowed. Using this characteristic, authors previously developed a voltage-based hot-spot detection method ...

Solvent accessible surface area (SASA) is an important descriptor of protein residues and atoms. It is widely used as an outstanding feature in hot spot prediction by many computational methods. However, SASA is not capable of distinguishing slightly buried residues, of which most are non hot spots, and deeply buried ones that are usually inside a hot spot. In this work, we propose a new descri...

Feature-based hot spots are localized regions where the attributes of objects attain high values. There is considerable interest in automatic identification of feature-based hot spots. This paper approaches the problem of finding feature-based hot spots from a data mining perspective, and describes a method that relies on supervised clustering to produce a list of hot spot regions. Supervised c...

We use new and archival Chandra data to investigate the X-ray emission from a large sample of compact hot spots of FR II radio galaxies and quasars from the 3C catalog. We find that only the most luminous hot spots tend to be in good agreement with the predictions of a synchrotron self-Compton model with equipartition magnetic fields. At low hot spot luminosities inverse Compton predictions are...

The activity of the M26 meiotic recombination hot spot of Schizosaccharomyces pombe depends on the presence of the heptamer 5'-ATGACGT-3'. Transplacement of DNA fragments containing the ade6-M26 gene to other chromosomal loci has previously demonstrated that the heptamer functions in some, but not all, transplacements, suggesting that hot spot activity depends on chromosomal context. In this st...
