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...

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...

The effective field theory (EFT) for a toy model of nucleons interacting via a short range and a long range Yukawa potential is presented. The scattering amplitude in the S0 channel is calculated up to next-to-next-to-leading order (NNLO) using the Kaplan-Savage-Wise (KSW) power counting scheme. A particular expansion of the amplitude about the pole at low (imaginary) momentum is used to derive...

How do media affect voting behavior? What difference can an independent media outlet make in a country with state-controlled media? Our paper addresses these questions by comparing electoral outcomes and votes reported by survey respondents during the 1999 parliamentary elections in Russia for those geographical areas that had access and those that had no access to the only national TV channel ...

Using the limit theorem for stochastic integral obtained by Jakubowski et al. (Probab. Theory Related Fields 81 (1989) 111–137), we introduce in this paper a new method for proving weak convergence results of empirical processes by a martingale method which allows discontinuities for the underlying distribution. This is applied to Nelson–Aalen and Kaplan–Meier processes. We also prove that the ...

It is often supposed that demonstratives and indexicals are devices of direct reference that they are, as David Kaplan puts it, terms which “refer directly without the mediation of a Fregean Sinn [or individual concept, set of properties, etc.] as meaning.“’ Most of the resistance to this view, I think, arises from the suspicion that it is not possible to give an acceptable treatment of the sem...
