The distributions of income and wealth in countries across the world are found to possess some robust and stable features independent of the specific economic, social and political conditions of the countries. We discuss a few physics-inspired multiagent dynamic models along with their microeconomic counterparts, that can produce the statistical features of the distributions observed in reality...
Gas distribution models can provide comprehensive information about a large number of gas concentration measurements, highlighting, for example, areas of unusual gas accumulation. They can also help to locate gas sources and to plan where future measurements should be carried out. Current physical modelling methods, however, are computationally expensive and not applicable for real world scenar...
Over 200 cases of actinide intake, occurring over the last 25 years, have been re-assessed. Cases were selected for which the intake date was known, there was both urine and faecal data and there was negligible interference from earlier intakes. The IMBA software was used to obtain a best fit to the data and establish an estimate of intake for each case. It is found that the magnitudes of the i...
based on the latest records of typhlops vermicularis merrem, 1820 from iran, this species is distributed in the northern and southern regions of the country. in this study, new records of typhlops vermicularis are presented and it is shown that distribution range of this species is extended towards the eastern and western iran, and according to the new distribution map, it can be assumed that t...
