PURPOSE Using magnetic resonance imaging (MRI), residual tumor cannot be differentiated from nonspecific postoperative changes in operated patients with brain gliomas. The higher specificity and sensitivity of L-(methyl-11C)-labeled methionine positron emissions tomography (MET-PET) in gliomas has been demonstrated in previous studies and is the rationale for the integration of this investigati...
Function indexed weighted sums and sequential residual empirical processes based on time-varying AR-processes are studied. It is shown that under appropriate assumptions non-parametric estimation of the parameter functions does not influence the asymptotic distribution of the residual empirical process. An exponential inequality for weighted sums of time-varying processes provides the basis for...
Abstract In this work, we are concerned with neural network guided goal-oriented a posteriori error estimation and adaptivity using the dual weighted residual method. The primal problem is solved classical Galerkin finite elements. adjoint in strong form feedforward two or three hidden layers. main objective of our approach to explore alternatives for solving greater potential numerical cost re...
<abstract><p>For solving large-scale consistent linear system, a greedy randomized Kaczmarz method with oblique projection and maximal weighted residual are proposed. By using projection, these two methods greatly reduce the number of iteration steps running time to find minimum norm solution, especially when rows matrix highly linearly correlated. Theoretical proof numerical result...
