This paper compares two variants of the Knox test in relation to space-time crime pattern analysis. A case study of H┌ヴェノ;ヴ┞ ;ミS けstolen-┗WエキIノWげ crime data sets of San Francisco city is presented. The comparative analysis shows that while one variant is designed to detect the sizes of the spatio-temporal neighbourhoods at which clustering (hotspots) is prominent within a data set, the other va...
The urban heat island (UHI) effect has become a hot topic in the global ecological environment. Research on UHI is of great significance for alleviating environmental problems. Therefore, it attracted extensive attention large number researchers field issues, such as ecologists, climatologists, planners, geographers, relevant policy makers, etc. However, systematic reviews are lacking research ...
Several hotspots of FRII radio sources have previously been detected in the X-ray at a flux level consistent with the X-rays being due to inverse-Compton scattering of radio “synchrotron photons synchrotron self-Compton”, if the magnetic fields in the hotspots are close to their equipartition values. However, the number of hotspots compact and bright enough to exhibit detectable X-ray emission ...
The spatial heterogeneity of malaria suggests that interventions may be targeted for maximum impact. It is unclear to what extent different metrics lead to consistent delineation of hotspot boundaries. Using data from a large community-based malaria survey in the western Kenyan highlands, we assessed the agreement between a model-based geostatistical (MBG) approach to detect hotspots using Plas...
We have found that most spontaneous mutations in the thyA gene of Escherichia coli selected for resistance to trimethoprim result from a TA to AT transversion at a single site within an imperfect inverted repeat or quasipalindrome sequence. This natural quasipalindrome within the coding region of thyA contains an extraordinarily potent hotspot for mutation. Our analysis provides evidence that t...
Dengue disease incidence is related with the construction of a house roof, which is an Aedes mosquito habitat. This study was conducted to classify pitch roof (PR) and flat roof (FR) surfaces using pan-sharpened Worldview 2 to identify dengue disease patterns (DDPs) and their association with DDP. A Supervised Minimum Distance classifier was applied to 653 training data from image object segmen...
Scientists and inventors can draw on an ever-expanding literature for the building blocks of tomorrow's ideas, yet little is known about how combinations of past work are related to future discoveries. Our analysis parameterizes the age distribution of a work's references and revealed three links between the age of prior knowledge and hit papers and patents. First, works that cite literature wi...
BACKGROUND According to the international criteria for hereditary non-polyposis colorectal cancer (HNPCC) diagnostics, cancer patients with a family history or early onset of colorectal tumours showing high microsatellite instability (MSI-H) should receive genetic counselling and be offered testing for germline mutations in DNA repair genes, mainly MLH1 and MSH2. Recently, an oncogenic V600E ho...
Lithography hotspot detection faces three challenges: 1) real hotspots are now harder to fix; 2) false alarm rate must be minimized; 3), full chip physical verification and optimization require fast turnaround. We propose a lithographic hotspot detection flow with ultra-fast speed and high fidelity that is especially suitable for guiding lithography-friendly design under real manufacturing cond...
In this issue of Cell, Lemoine et al. monitor chromosome instability in yeast cells with reduced levels of an essential replicative DNA polymerase. The authors identify a hotspot for chromosome aberrations reminiscent of fragile sites in human cells. This hotspot is composed of inverted Ty elements, which lead to a double-strand break under conditions of limited replication.
