Boris Ephrussi (1901-1979)

Boris Ephrussi studied fruit flies, yeast, and mouse [3] genetics and development while working in France and the US during the twentieth century. In yeast, Ephrussi studied how mutations in the cytoplasm persisted across generations. In mice he studied the genetics of hybrids and the development of cancer. Working with George Wells Beadle [4] on the causes of different eye colors in fruit flie...

CHAPTER FOUR PROTACTINIUM Boris

Protactinium, element 91, is one of the most rare of the naturally occurring elements and may well be the most difficult of all to extract from natural sources. Protactinium is, formally, the third element of the actinide series and the first having a 5f electron. The superconducting properties of protactinium metal provide clear evidence that Pa is a true actinide element (Smith et al., 1979)....

Yes Sir, no Sir, not much difference Sir.

OBJECTIVE To assess whether making the sender's knighthood explicit in a series of letters would have any detectable effect on the response. DESIGN A random sequence was generated by flipping a coin to determine whether a letter would have 'Sir Iain Chalmers' or 'Iain Chalmers' typed under the signature. This sequence was prepared independently of the preparation of an alphabetic list of the ...

A high-order Boris integrator

This work introduces the high-order Boris-SDC method for integrating the equations of motion for electrically charged particles in an electric and magnetic fields. Boris-SDC relies on a combination of the Boris-integrator with spectral deferred corrections (SDC). SDC can be considered as preconditioned Picard iteration to compute the stages of a collocation method. In this interpretation, inver...
