The existence and stability of localized patterns of criminal activity are studied for the reaction-diffusion model of urban crime that was introduced by Short et. al. [Math. Models. Meth. Appl. Sci., 18, Suppl. (2008), pp. 1249–1267]. Such patterns, characterized by the concentration of criminal activity in localized spatial regions, are referred to as hot-spot patterns and they occur in a par...
Accurately assessing and optimizing the implosion performance of inertial confinement fusion capsules is a crucial step to achieving ignition on the NIF. We have applied differential filtering (matched Ross filter pairs) to provide broadband time-integrated absolute x-ray self-emission images of the imploded core of cryogenic layered implosions. This diagnostic measures the temperature- and den...
[1] Helium isotopes are a robust geochemical tracer of a primordial mantle component in hot spot volcanism. The high He/He (up to 35 RA, where RA is the atmospheric He/He ratio of 1.39 10 ) of some Hawaiian Island volcanism is perhaps the classic example. New results for picrites and basalts from the Hawaiian-Emperor seamount chain indicate that the hot spot has produced high He/He lavas for at...
Multistage interconnection networks (MIN) are used to connect processors to memories in shared memory multiprocessor systems. They have also been proposed as switching fabrics in ATM switches in Broadband ISDN networks. A multistage network consists of several stages of switching elements (SE) connected by a permutation function. Since routing connicts among packets at the SEs cause blocking an...
filling defects are often observed on 99mtc sulfur colloid liver scans. hot spots are much less frequently seen. superior vena cava syndrome is the most frequent cause of this finding. in this report 3 patients with s.v.c and budd - chiari syndrome with hot spot on liver scan are presented. mechanisms of scintigraphic patterns are reviewed.
Objective To assess the performance of a whole-tumor histogram analysis of apparent diffusion coefficient (ADC) maps in differentiating thymic carcinoma from lymphoma, and compare it with that of a commonly used hot-spot region-of-interest (ROI)-based ADC measurement. Materials and Methods Diffusion weighted imaging data of 15 patients with thymic carcinoma and 13 patients with lymphoma were ...
To develop appropriate measures to prevent soil contamination in abandoned mining areas, an understanding of the spatial variation of the potentially toxic trace elements (PTEs) in the soil is necessary. For the purpose of effective soil sampling, this study uses hot spot analysis, which calculates a z-score based on the Getis-Ord Gi* statistic to identify a statistically significant hot spot s...
This paper proposes a coordinated defense scheme of distributed denial of service (DDoS) network attacks, based on the backward-propagation, on-off control strategy. When a DDoS attack is in effect, a high concentration of malicious packet streams are routed to the victim in a short time, making it a hot spot. A similar problem has been observed in multiprocessor systems, where a hot spot is fo...
