The existence of hepatocellular and cholangiocellular carcinomata, arising from liver cells and bile duct epithelium respectively, has long been recognized, although the proportions of each type have varied in different series. Gustafson (1937) reported 39 liver cell and 11 bile duct tumours amongst 62 cases of primary liver carcinoma based on 24,400 necropsies, and Wilbur, Wood, and Willett (1...

Introduction In this paper we consider cell centered nite di erence approximations for second order convection di usion equations of divergence type Our goal is to construct nite di erence methods of second order of approximation that satisfy the discrete maximum principle The error estimates are in the discrete Sobolev spaces associated with the considered boundary value problem Approximation ...

in this research, the framework is presented for unsupervised change detection using multitemporal sar images based on integration clustering and level set methods. spatial correlation between pixels were considered by using contextual information. also as proposed method was used integration of gustafson-kessel clustering techniques (gkc) and level set methods for change detection. using clust...

In earlier work, this author has explained the robustness of nonlinear multilayer machine learning algorithms in terms of an intrinsic chaos of the logistic map. Moreover we have connected that dynamics to a spectral concentration which occurs in bounded-to-free quantum transitions. From these, one may formulate a fundamental irreversibility common to both machine and quantum learning. Second, ...

Most of the techniques on identifying fault location depend on parameters of power transmission line. Thus, a complex mathematical solution will be considered which at such conditions, the dependence on line parameters will limit performance of algorithms. An independent or parameters free algorithm is an option to overcome this problem by using an artificial intelligent technique. This paper p...

In vitro studies have shown that addition of antifibrinolytic agents to culture media containing explants of cat palatal mucosa will change the direction of the epithelial proliferation. Consequently, the epithelial cells migrate in an opposite direction to that expected, reaching the stratum corneum and spreading in the upper surface with the formation of an everted epiboly (Bergenholtz, Gusta...
