PURPOSE COPD is a progressive disease, which can take different routes, leading to great heterogeneity. The aim of the post-hoc analysis reported here was to perform continuous analyses of advanced lung function measurements, using linear and nonlinear regressions. PATIENTS AND METHODS Fifty-one COPD patients with mild to very severe disease (Global Initiative for Chronic Obstructive Lung Dis...

This paper proposes a quasi-maximum likelihood (QML) estimator of the break point for large-dimensional factor models with single structural in loading matrix. We show that QML is consistent true when covariance matrix pre- or post-break (or both) singular. Consistency here means deviation estimated date from k0 converges to zero as sample size grows. much stronger result than fraction kˆ/T bei...

The Liouvillian exceptional points for a quantum Markovian master equation of an oscillator in generic environment are obtained. They occur at the when modified frequency vanishes, whereby eigenvalues become real. In system there two parameters that modify oscillator's natural frequency. One can be damping rate. point then corresponds to critical oscillator. This situation is illustrated by Cal...
