CRUSTAL STRUCTURE AND SURFACE-WAVE DISPERSION* By MAURICE EwING and FRANK PRESS

A RECENT seismic refraction profile1 in 2,800 fm. (5.1 km.) at latitude 34° 00' N, longitude 66° 30' W, in the Atlantic Ocean proved that basement rocks having a velocity of 7.58 km/sec. for compressional waves were covered by 1.37 km. of sediment. We tentatively identified this velocity with either the P n velocities used in earthquake seismology for the ultra basic layer immediately beneath t...

However, I have received many comments from people who, upon hearing of his death, remarked along lines similar to these: “It’s the end of an...

In this series of studies, we used a monkey model of human hemispherectomy in order to characterize behavioral recovery and anatomical reorganization of the visual system. Monkeys were tested neurobehaviorally on a variety of tests every 6 months for a period of 30 months. Thereafter, the organization of the retinofugal pathways was studied by means of histological techniques. At the behavioral...

In memoriam Maurice Gross

Maurice Gross (1934-2001) was both a great linguist and a pioneer in natural language processing. This article is written in homage to his memory. Maurice Gross is remembered as a vital man surrounded by a lively group, constituted by his laboratory, the LADL, and by his international network, RELEX. He and his group always resolutely steered away from any kind of abstemiousness or abstinence. ...
