Existence of a nonequilibrium tricritical point has been revealed in the Hamiltonian mean-field model by a nonequilibrium statistical mechanics. This statistical mechanics gives a distribution function containing unknown parameters, and the parameters are determined by solving simultaneous equations depending on a given initial state. Due to difficulty in solving these equations, pointwise nume...

BACKGROUND Inappropriate and unnecessary implantable cardioverter-defibrillator shocks continue to be highly prevalent. METHODS AND RESULTS We prospectively evaluated a new algorithm for discriminating supraventricular (SVT) and ventricular (VT) tachycardias with 1:1 atrioventricular association that is based on the response of the arrhythmia to simultaneous or convergent dual-chamber antitac...

Background—Inappropriate and unnecessary implantable cardioverter-defibrillator shocks continue to be highly prevalent. Methods and Results—We prospectively evaluated a new algorithm for discriminating supraventricular (SVT) and ventricular (VT) tachycardias with 1:1 atrioventricular association that is based on the response of the arrhythmia to simultaneous or convergent dual-chamber antitachy...

A nonlinear equation system for individual tree diameter growth and mortality of natural Mongolian oak forests was developed based on 13,360 observations from 195 permanent sample plots in Northeast China. Weighted regression was used in a distance-independent diameter growth equation for dealing with heterocedasticity. Since diameter growth and mortality models have common predictors including...

In the present study a new economic and rapid bacterial micro-assay for simultaneous detection and quantitative measurement of serum galactose was developed. Analysis of the standard curve showed a linearity range for galactose from 2 mg/dL to 180 mg/dL with a regression equation of Y = 0.013X ? 0.083; R² = 0.962. The advantage of the method is its ability to measure serum galactose quantitativ...
