The technique used to visualize the spatial distribution of components such as biomarker, metabolites, proteins by their molecular masses is known as imaging mass spectrometry. The emerging technologies in the field of imaging mass spectrometry are MALDI imaging and SIMS imaging.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
