Profile of Edward M. De Robertis.

Curiosity about the mysterious workings of embryos fuels the research of embryologist Edward M. De Robertis (also known as Eddy), who was elected to the National Academy of Sciences in 2013. His isolation of genes that control head-to-tail and backto-belly patterning in early frog and mouse embryos led to the discovery that animal development is controlled by an ancient genetic toolkit. De Robe...

Potential danger for children and for myself! Risky behaviour on the verg...

On a Greedy Heuristic for Complete Matching * Edward M . Reingold

, Finding a minimum weighted complete matching on a set of vertices in which the distances satisfy the triangle inequality is of general interest and of particular importance when drawing graphs on a mechanical plotter. The "greedy" heuristic of repeatedly matching the two closest unmatched points can be implemented in worst-case time O(n log n), a reasonable savings compared to the general min...

Since then, increasingly sophisticated mathematical and statistical tools have been brought to bear on the problem of estimating the aggregate risk of a portfolio. This risk depends crucially on the covariances ...
