The concept of wave propagation and the interaction of waves with matter is pivotal in many fields of physics and engineering (e. g. radio transmission, optics, sound propagation, transmission of information in waveguides...). Therefore wave propagation plays a central role in teaching physics, electrical engineering, information technology etc. from the undergraduate level (undergratuate engin...

Response to Hartwig and Davies

and indeed many of the other analyses reported in our paper do not suffer from potential bias due to weak instruments. Hartwig and Davies did, however, suggest that we could have used estimates from an external source to obtain less biased results in our MR-Egger analyses. Whereas we agree that this would be good practice in most situations, we do not feel that it would have been appropriate in...

Memoriam.

George W. Housner, Carl F Braun Professor of Engineering, emeritus, died after a short illness on 10 November 2008, just a few weeks before his 98th birthday. He was in the retirement home in Pasadena where he had lived for several years. For all of us who knew George, this marked the end of an era. Few people have guided and nurtured a field the way George led earthquake engineering over a per...
