Mark Hanson: a developmental health pioneer

Ernst Hadorn, a pioneer of developmental genetics.

This article gives a short and personal portrait of Ernst Hadorn (1902-1976), one of the most influential developmental biologists in Europe. Hadorn initially worked with amphibia, but then soon turned to Drosophila where he very successfully studied lethal factors and the development of imaginal disks.

Hawaii: A Pioneer In Health System Reform

Eguchi-Hanson Solitons

We present a new class of solutions in odd dimensions to Einstein’s equations containing either a positive or negative cosmological constant. These solutions resemble the even-dimensional Eguchi-Hanson(A)dS metrics, with the added feature of having Lorentzian signatures. They provide an affirmative answer to the open question as to whether or not there exist solutions with negative cosmological...

Robin Hanson for Bayesian

Consider two agents who want to be Bayesians with a common prior, but who cannot due to computational limitations. If these agents agree that their estimates are consistent with certain easy-to-compute consistency constraints, then they can agree to disagree about any random variable only if they also agree to disagree, to a similar degree and in a stronger sense, about an average error. Yet av...

Estimates of crustal and lithospheric thickness beneath ten permanent seismic stations in southern, central, and eastern Africa have been obtained from modeling S-wave receiver functions (SRFs). For eight of the examined stations, the Moho depth estimates agree well with estimates from previous studies using P-wave receiver functions (PRFs). For two stations, TSUM and BGCA, previous PRF estimat...
