The motion of a building depends on the excitation, the coupling of the building to the ground, and the mechanical properties of the building. We separate the building response from the excitation and the ground coupling by deconvolving the motion recorded at different levels in the building and apply this to recordings of the motion in the Robert A.(More)
The Southern California Seismic Network (SCSN) has recently installed seismic stations in two buildings on the Caltech campus (Millikan Library and the Broad Center). Continuous real-time accelerometer data from these structures are now freely available to the community. This dataset provides a new opportunity to observe, and better understand, the(More)
is among the most cited theories in cognitive psychology. 1 However, the theory has had a mixed scientific reception. On the one hand, it has few proponents within the field of speech perception, and many authors cite it primarily to offer critical commentary (e.g., Sussman, 1989). On the other hand, it is perhaps the only theory of speech perception(More)
'As genomics and epidemiology begin to intersect, there is the potential for both fields to be altered in ways that are mutually beneficial' (R Millikan 1) While observational epidemiology is considered to be the scientific foundation of public health 2 it is often viewed as a 'soft science' limited by an inherent inability to fully control for confounding,(More)
It was as early as 1903 that the British physicists, McLennan and Burton' and Rutherford and Cooke2 noticed that the rate of leakage of an electric charge from an electroscope within an airtight metal chamber could be reduced as much as 30% by enclosing the chamber within a completely encircling metal shield or box with walls several centimeters thick.

We celebrate Andy Benson's 93rd birthday on September 24, 2010 through this Editorial. This short account about Andy Benson should serve as a prelude to the short article that Andy has written for the entire pho-tosynthesis community, which gives a glimpse of why he left the field of the ''path of carbon in photosynthesis,'' when he had already discovered,(More)
