Taking Scopus database as data source, CiteSpace was used to construct knowledge map of environmental cost accounting research, and the current research hotspots future trends in this field were analyzed. According results, relevant suggestions are put forward provide reference for development research.

This paper is to explore new ways to better understand urban system emphasizing on detection and analysis of urban area hotspots through cell phone traffic data. Firstly, according to the characteristics of GSM network, Voronoi cellular network is introduced to determine the service area of the base station. Then two visualization methods are discussed through analyzing the distribution of cell...

Single-molecule surface-enhanced Raman spectroscopy (SERS) has attracted increasing interest for chemical and biochemical sensing. Many conventional substrates have a broad distribution of SERS enhancements, which compromise reproducibility and result in slow response times for single-molecule detection. Here we report a smart plasmonic sensor that can reversibly trap a single molecule at hotsp...

Gene duplication generates new genetic material, which has been shown to lead to major innovations in unicellular and multicellular organisms. A whole-genome duplication occurred in the ancestor of Saccharomyces yeast species but 92% of duplicates returned to single-copy genes shortly after duplication. The persisting duplicated genes in Saccharomyces led to the origin of major metabolic innova...

A large number of hprt-mutants were obtained by treating human lymphoblast cells (TK6) with 5 microM K2Cr2O7 for 5 hr and selecting by growth in 6-thioguanine. A combination of high fidelity polymerase chain reaction (PCR) and denaturing gradient gel electrophoresis (DGGE) allowed us to measure mutant frequencies as a function of DNA sequence. Chromium(VI) induced four hotspots in a 104 bp doma...

As minimum feature sizes shrink, unexpected hotspots appear on wafers. Therefore, it is critical to detect and fix these hotspots at design stage to reduce development time and manufacturing cost. Currently, the most accurate approach to detect such hotspots is lithography simulation. However, it is known to be time-consuming. This paper proposes a new hotspot detection method with both a regre...

BACKGROUND In 2002, the WHO declared interpersonal violence to be a leading public health problem. Previous research demonstrates that urban spaces with a high incidence of violent trauma (hotspots) correlate with features of built environment and social determinants. However, there are few studies that analyse injury data across the axes of both space and time to characterise injury-environmen...

Natural variation in gene expression is pervasive within and between species, and it likely explains a significant fraction of phenotypic variation between individuals. Phenotypic variation in acute systemic responses can also be leveraged to reveal physiological differences in how individuals perceive and respond to environmental perturbations. We previously found extensive variation in the tr...

Solutions will be effective if they are aligned with the problems that trying to solve. This paper studied most relevant social impacts of textile industry and how appropriately companies manage these impacts, in order achieve greater sustainability global supply chains. Therefore, we attempted determine whether belonging product lifecycle identify keeping hotspots chain industry. A consistency...
