Cospectral Graphs on 12 Vertices

We found the characteristic polynomials for all graphs on 12 vertices, and report statistics related to the number of cospectral graphs.

+ 12 or trisomy 12

Phenotype/cell stem origin virgin CD5+ recirculating B-cell; the classical CLL phenotype is CD5+, CD23+, CD22-, CD79a-, FMC7-, sIg weak; trisomy 12 is more often observed in CLL with morphologically and immunologically atypical cells, displaying CD5 negativity or FMC7 positivity and strong surface immunoglobulin staining; trisomy 12 is present in proliferating cells and seems to be associated w...

A Note on ∆ lnL = � 12 Errors

The points at which the log likelihood falls by 1 2 from its maximum value are often used to give the ‘errors’ on a result, i.e. the 68% central confidence interval. The validity of this is examined for two simple cases: a lifetime measurement and a Poisson measurement. Results are compared with the exact Neyman construction and with the simple Bartlett approximation. It is shown that the accur...

Notes on Price Measurement August 12, 2012

When detailed price and quantity information is available for components of the CPI, it becomes possible to produce month to month superlative indexes for these components. As we saw at the end of the last Chapter, these superlative month to month indexes can be subject to a considerable amount of chain drift. Thus in this Chapter, we will review recent methods that have been suggested to overc...
