Costas Anastassiou, a postdoctoral scholar working with Professor Christof Koch, and colleagues have found that coordinated behavior occurs in the brain whether or not neurons are actually connected via synapses.  To tease out the effects, Anastassiou and his colleagues, focused on strong but slowly oscillating fields, called local field potentials (LFP), that arise from neural circuits composed of just a few rat brain cells.  Measuring those fields and their effects required positioning a cluster of tiny electrodes within a volume equivalent to that of a single cell body—and at distances of less than 50 millionths of a meter from one another.

Amnon Yariv, Martin and Eileen Summerfield Professor of Applied Physics and Professor of Electrical Engineering, has received one of the highest honors bestowed by the United States government on scientists, and engineers. He is a recipient of the National Medal of Science. Professor Yariv's research group has pioneered the field of optoelectronics. Many innovations such as distributed Feedback (DFB) Semiconductor Lasers, Integrated Optoelectronic Circuits, Optical Phase Conjugation, External Cavity Tunable Semiconductor Lasers, Quantum Well Infrared Photodetectors (QWIP's), and all-fiber add/drop filters have found their beginnings in his research group. Currently, his group’s research aims at developing the new technologies that will be mandated by the seemingly endless appetite for optical bandwidth. Specifically, they are working at extending, to the field of laser optics, some key ideas that form the foundation of the microwaves and the radio frequencies fields.

Jehoshua Bruck, Gordon and Betty Moore Professor of Computation and Neural Systems and Electrical Engineering, and colleagues' paper entitled Rank Modulation for Flash Memories has received the Institute of Electrical and Electronics Engineers (IEEE) Best Paper Award in Signal Processing and Coding for Data Storage. Rank modulation is a novel data representation scheme which the group has developed for multilevel flash memory cells. The idea is that a set of cells stores information in the permutation induced by the relative charge levels of the individual cells. As opposed to iterative (and slow) programming in current technology, rank modulation allows fast programming that is based on push-to-the-top operations, namely, raising the charge level of a single cell to be the highest one.

Peter H. Siegel, Faculty Associate in Electrical Engineering and a Member of the Professional Staff in Biology, has been selected by the IEEE to spearhead a new journal: IEEE Transactions on Terahertz Science and Technology. The journal will highlight activities in the emerging field of far-infrared technology (wavelength range between 1mm and 10 microns) with applications in high frequency communications, space, Earth and planetary science, ultrafast chemistry and physics, defense and security and even art history and preservation. The inaugural issue is slated for the fall of 2011.
