* It has, however, been shown by Du Buy that the curvatures obtained are reduced when higher concentrations of agar are employed. Our value of K/v applies to 1.5% agar. Boner, J. F., Biol.

We analyze a blind channel impulse response identification scheme based on the cross correlation of blind symbol estimates with the received signal. The symbol estimates specified are those minimizing the Godard (or constant modulus) criterion, for which mean-squared symbol estimation error bounds have recently been derived. In this paper, we derive upper bounds for the average squared paramete...

Robert P. Perry On July 15, Robert Palese Perry—‘‘Bob’’ to those who knew him—passed away at the age of 82. Bob was a pioneer in studying gene transcription in mammalian cells, a wonderful mentor to his preand postdoctoral students, and a compassionate family man. He leaves behind his wife Zoila, a well-known sculptor with whom he enjoyed a happy marriage for 57 years, his two daughters Adele a...

B asil Gordon, who made major research contributions to number theory, combinatorics, and algebra and who enhanced our understanding of Ramanujan’s remarkable identities, passed away on January 12, 2012, at the age of eighty. Gordon, who was a professor of mathematics at UCLA, was an outstanding teacher at all levels. His legacy will continue, owing to the impact of his fundamental work and to ...

DOI: http://dx.doi.org/10.1090/noti1247 received both the Steele Prize for Seminal Contributions to Research (from the AMS, 1998) and the Deborah and Franklin Tepper Haimo Award for Distinguished Teaching (from the MAA, 1996). During his long tenure at Penn he advised twenty-six PhD students and won additional awards, including the Christian and Mary Lindback Award for excellence in undergradua...

Graphs are often used in artificial intelligence as means for symbolic knowledge representation. A graph is nothing more than a collection of symbols connected to each other in some fashion. For example, in computer vision a graph with five nodes and some edges can represent a table – where nodes correspond to particular shape descriptors for legs and a top, and edges to particular spatial rela...

A fast fault-tolerant controller structure is presented, which is capable of recovering from transient faults by performing a rollback operation in hardware. The proposed fault-tolerant controller structure utilizes the rollback hardware also for system mode and this way achieves performance improvements of more than 50% compared to controller structures made fault tolerant by conventional tech...
