Homological Sensor Networks, Volume 54, Number 1

10 NOTICES OF THE AMS VOLUME 54, NUMBER 1 Sensors and Sense-ability A sensor is a device that measures some feature of a domain or environment and returns a signal from which information may be extracted. Sensors vary in scope, resolution, and ability. The information they return can be as simple as a binary flag, as with a metal detector that beeps to indicate a detection threshold being cross...

Presidents, Vice Presidents, and Death: Closing the Constitution's Succession Gap

Underwriting the presidents.

The United States has had 43 presidents. We examined whether they survive significantly longer or shorter than their contemporaries. We found that survival was better for presidents elected in the 1789-1841 and 1933-2001 periods (SMRs of 0.7 and 0.6, respectively), but worse for those elected in 1845-1929 (SMR = 2.9). We also found increased mortality during the years lived in office (SMR = 1.4...

Presidents who value science.

www.sciencemag.org SCIENCE VOL 323 13 FEBRUARY 2009 843 COVER An image of Mare Moscoviense on the lunar farside, taken by the Terrain Camera aboard the SELENE (Kaguya) spacecraft on 17 January 2008. Crater frequency distributions derived from such images yield ages of about 2.5 billion years for several volcanic deposits in this mare, indicating that volcanism on the lunar farside lasted about ...

Mikio Sato, a Visionary of Mathematics, Volume 54, Number 2

Like singularities in mathematics and physics, ideas propagate, and the speed of propagation depends highly on the energy put into promoting them. Mikio Sato did not spend a great deal of time or energy popularizing his ideas. We can hope that his receipt of the 2002/2003 Wolf Prize 1 will help make better known his deep work, which is perhaps too original to be immediately accepted. Sato does ...
