This paper here introduced a novel semiring structure involving nonnegative integers, where operations depended on the comparison of the magnitudes of decimal digit sums.Consequently, a corresponding matrix semiring can be established on this commutative semiring.We showed that the 3-satisfiability problem can be polynomial-time reduced to solving
Pit latrines are used by billions of people globally, often in developing countries where they provide a low-tech and low-cost sanitation method.However, health and social problems can arise from a lack of emptying or maintenance of these facilities.A better understanding of the biological and environmental parameters within pit latrines could info
Desert segmentation of remote sensing images is the basis of analysis of desert area.Desert images are usually characterized by large image size, large-scale change, and irregular location distribution of surface objects.The multi-scale fusion method is widely used in the existing deep learning segmentation models 730 sunken lake road to solve the
