A hot spot of a program is a program region, whose execution time crucially impacts the overall execution time of the program. A hot spot can often be optimized without fully analyzing the whole program. This is supported by approaches for demand-driven data-flow analysis. Particularly successful in practice turned out to be an approach based on reverse data-flow analysis. In this paper, we rec...

The winding hot-spot temperature is one of the most critical parameters that affect the useful life of the power transformers. The winding hot-spot temperature can be calculated as function of the top-oil temperature that can estimated by using the ambient temperature and transformer loading measured data. This paper proposes the estimation of the top-oil temperature by using a method based on ...

We present multi-color photometry and time resolved spectroscopy of OU Vir. The analysis of the quiescent light curve shows that OU Vir is characterized by i) strong cycle-to-cycle brightness variations, and ii) hot spot modulated light curve with grazing eclipse of the impact region. Colors are derived both in-and out-of eclipse. The time-resolved spectroscopy allows us to produce the radial v...

We report on measurements of the electron temperature in the hotspot of inertially confined, layered, spherical implosions on the National Ignition Facility using a differential filtering diagnostic. Measurements of the DT and DD ion temperatures using neutron time-of-flight detectors are complicated by the contribution of hot spot motion to the peak width, which produce an apparent temperature...

We present a new type of nanoparticle-based DNA sensor using surface-enhanced Raman scattering (SERS) on gold nanoparticle (Au NP) aggregates formed by DNA photoligation. The DNA sensor exploits the photoligation reaction between oligodeoxynucleotides (ODNs) attached to the surfaces of Au NPs in the presence of target DNA (T-DNA). When hybridization takes place between the ODNs and T-DNA, Au NP...

A protein interface can be as "wet" as a protein surface in terms of the number of immobilized water molecules. This important water information has not been explicitly taken by computational methods to model and identify protein binding hot spots, overlooking the water role in forming interface hydrogen bonds and in filing cavities. Hot spot residues are usually clustered at the core of the pr...

The KFC Server is a web-based implementation of the KFC (Knowledge-based FADE and Contacts) model-a machine learning approach for the prediction of binding hot spots, or the subset of residues that account for most of a protein interface's; binding free energy. The server facilitates the automated analysis of a user submitted protein-protein or protein-DNA interface and the visualization of its...

Mechanical action can produce dramatic physical and mechanochemical effects when the energy is spatially or temporally concentrated. An important example of such phenomena in solids is the mechanical initiation of explosions, which has long been speculated to result from 'hot spot' generation at localized microstructures in the energetic material. Direct experimental evidence of such hot spots,...

Hot spots with a large electric field enhancement usually come in small volumes, limiting their applications in surface-enhanced spectroscopy. Using a finite-difference time-domain method, we demonstrate that spiky nanoparticle dimers (SNPD) can provide hot spots with both large electric field enhancement and large volumes because of the pronounced lightning rod effect of spiky nanoparticles. W...

Many database optimization activities, such as prefetching, data clustering and partitioning, and buuer allocation, depend on the detection of hot spots in access patterns. While a database designer can in some cases use special knowledge about the data and the users to predict hot spots, in general one must use information about past activity to predict future activity. However, algorithms tha...
