BACKGROUND In survival analysis, patients on peritoneal dialysis are confronted with three different outcomes: transfer to hemodialysis, renal transplantation, or death. The Kaplan-Meier method takes into account one event only, so whether it adequately considers these different risks is questionable. The more recent competing risks method has been shown to be more appropriate in analyzing such...

The current status of effective field theory (EFT) descriptions of nucleon-nucleon (NN) interactions is briefly reviewed, and a new formulation of EFT which treats pion interactions perturba-tively is presented. This approach differs from the Kaplan-Savage-Wise (KSW) expansion in that the singular short distance part of the pion tensor interaction is summed to all orders.

We have established a new convergent scheme to treat analytically nucleon-nucleon interactions from a chiral effective field theory. The Kaplan-Savage-Wise (KSW) amplitudes are resummed to fulfill the unitarity or right hand cut to all orders below pion production threshold. This is achieved by matching order by order in the KSW power counting the general expression of a partial wave with resum...

Consider a long term study, where a series of dependent and possibly censored failure times is observed. Suppose that the failure times have a common marginal distribution function, but they exhibit a mode of time series structure such as-mixing. The inferences on the marginal distribution function are of our interest. The main results of this paper show that under some regularity conditions, t...

An accurate and robust EEG source localization algorithm is an asset in the understanding, diagnosis, and treatment of some neurological disorders. Two inverse algorithms, LORETA and the Borgiotti-Kaplan beamformer (BK Beam) are used to localize a single dipole source from a simulated EEG within a realistic head model. Compared over a range of SNR values and source locations, the BK Beam exhibi...
