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)
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)
