A gradient system solution method is presented for solving Potts mean field equations for combinatorial optimization problems subject to winner-take-all constraints. In the proposed solution method the optimum solution is searched by using gradient descent differential equations whose trajectory is confined within the feasible solution space of optimization(More)
PURPOSE Liver demonstrates a heterogeneous (18)F fluoro-2-deoxy-D: -glucose ((18)F-FDG) uptake pattern and sometimes shows an abnormally increased uptake even when there is no malignant tissue. The aim of this study was to evaluate the relationships of liver (18)F-FDG uptake as related to physical factors, fatty liver, blood glucose (BG), and other(More)
