TCP models based on Poisson statistics are characterizing the distribution of surviving clonogens. It enables calculation for individuals. In order to describe clinically observed survival data patient cohorts it is necessary extend model. This typically done by either incorporating variations various model parameters, or using an empirical logistic The purpose this work development analytical ...

We present the photometric and spectroscopic study of the very luminous Type IIn SN 2006gy for a time period spanning more than one year. The evolution of multiband light curves, the pseudo-bolometric (BVRI) light curve and an extended spectral sequence are used to derive constraints on the origin and evolution of the SN. A broad, bright (MR ∼ −21.7) peak characterizes all monochromatic light c...

This other work is concerned with field-element to lineal-element transformations. See Kasn...
