Scalar or right-chiral interaction currents may be expected to produce a neutrino coupled to the electron which is different from, and perhaps even orthogonal to, that coupled to the electron by the standard model weak interaction. We show that, using reasonable parameter values for such additional interactions, it is possible to generate a spectrum which, if analyzed in the manner commonly emp...

The estimation of feature relevance in the framework of supervised classification problems has a great practical significance. Nevertheless, to solve this problem in real situations it is not always an easy task. One of the complex situations appears when the result of comparison between two coordinate values of the description of the respective objects is a real number. Goldman typical testors...

Cardiac complications comprise as much as 50% of perioperative vascular surgical morbidity and mortality. Using the Goldman multifactorial index for evaluating cardiac risk pre-operatively, 53 consecutive patients who underwent abdominal aortic aneurysm surgery were prospectively studied. Forty patients (75.5%) were also evaluated with echocardiography for assessment of left ventricular functio...

Likelihood ratio tests (LRTs) for comparing models of sequence evolution have become popular over the last few years (Goldman 1993; Yang, Goldman and Friday 1994, 1995; Huelsenbeck and Crandall 1997; Huelsenbeck and Rannala 1997). In their simplest form, such tests compare a simpler null hypothesis (H0) with a more complex alternative hypotheses (H1) which is a generalization of H0. H0 can be d...
