[Insufficient CT scan in visualizing an intracerebral parenchymal damage in a six-month-old boy].

A six-month-old boy fell over, and a crochet hook penetrated his skin underneath his left eye. The hook was removed, and an emergency physician found a Glasgow Coma Scale score of 6-7. A CT scan showed no cerebral or ophthalmic injury.

Statistical Inference in the Wright-Fisher Model Using Allele Frequency Data.

The Wright–Fisher model provides an elegant mathematical framework for understanding allele frequency data. In particular, the model can be used to infer the demographic history of species and identify loci under selection. A crucial quantity for inference under the Wright–Fisher model is the distribution of allele frequencies (DAF).
