Additionally, we show how the DEM inversion method can be adapted to simultaneously invert AIA and XRT data, and how supplementing AIA data with the latter improves the inversion result.  ...  We then present results from the application of the method to AIA observations of Active Region 11158, comparing the region's thermal structure on two successive solar rotations.  ...  As the bottom panel of Fig. 4 illustrates, the discrepancy is mainly due to missing EM in the high temperature bins.  ...

Quantifying recent variation and relatedness in human populations

One draw-back of these two algorithms is the dependence on phased haplotype data as input - a constraint that becomes more difficult with large populations.  ...  Our novel seed-based algorithm, GERMLINE, can reduce the computational burden of finding pairwise segments from quadratic to nearly linear time in a general population.  ...  Such methods tend to seek a parsimonious set of haplotypes to explain the data based on available homozygous sites 36 , or attempt to reconstruct the coalescent process relating observed individuals and  ...
