Charting the Dynamics of Neurocognitive Networks

Steven L. Bressler, Ph.D.
Professor, Center for Complex Systems & Brain Sciences, Florida Atlantic UniversityAbstract:
There has long been a dichotomy in understanding higher-order functions of the cerebral cortex. The localizationist tradition has sought to identify such functions with specific cortical areas, whereas the globalist tradition has viewed all higher-order functions as emerging from the cerebral cortex as a whole. A reconciliation of these opposing viewpoints has come with the growing realization that neurocognitive networks are of central importance to cortical function. Neurocognitive networks are composed of distributed neuronal assemblies in the cortex and sub cortical structures that dynamically engage in cooperative interactions to accomplish specific cognitive operations. A major challenge for cognitive neuroscience is to develop analytic tools for the precise characterization of the dynamics of neurocognitive networks. I will describe an approach to this characterization based on the construction of network graphs derived from autoregressive time series analysis of cortical population activity. I will also present experimental evidence from non-human primates and humans that this approach provides useful insights into the neural basis of cognitive function.Location: Olin Hall of Engineering (OHE) - 100C (Studio C)

A Methodology for Creating Application Specific Processor Architectures
Mon, Jun 11, 2007 @ 02:30 PM - 03:30 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
*Professor Kumar will be available 4-5pm in EEB-248 to talk to PhD students from any engineering department interested in faculty positions at IIT Delhi.Abstract:
Performance improvement through datapath extensions with Application Specific Functional Units has been a subject of research for more than a decade now. However, we feel that full potential of this approach has not been exploited due to several obstacles. This talk presents techniques to get past some of these obstacles.Usually a cluster of operations identified from the application defines a new custom instruction and forms the behavior of an Application Specific Functional Unit that implements this instruction. In the techniques available for identifying such clusters, the number of register file ports constrains the number of inputs and outputs for a legal operation cluster, thus limiting the overall achievable speedup. We present a technique that circumvents the constraints imposed by register file ports and results in a significantly higher speed up. In addition, our identification algorithm runs 2 to 3 orders faster than a typical I/O constrained identification approach.The second issue we take up here is estimation of the speedup achievable for the clusters identified. In order to select the right clusters, we need to correctly estimate the speedup taking into account what we call as temporal and spatial reuse of the clusters. In absence of efficient techniques to do so, researchers compromise either on the quality of estimates or on the number of clusters examined. We propose a novel method by which each cluster’s reuse information can be derived very efficiently, making it possible to generate high quality custom instructions.Bio:

Electro-Thermal Interaction in Nanoscale Devices: Carbon Nanotubes and Phase-Change Memory

Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
Nanotechnology Seminar:Electro-Thermal Interaction in Nanoscale Devices:Carbon Nanotubes and Phase-Change MemoryEric PopAssistant Professor
Department of Electrical Engineering
University of Illinois at Urbana-Champaign (UIUC)AbstractRising power densities are often considered the ultimate roadblock in the evolution of nanoelectronics. From a device perspective, high power densities in small volumes are complicated by reduced thermal conductance, and the thermal impedance of material interfaces. This talk will focus on two relatively novel devices, carbon nanotubes and phase-change memory, where the electro-thermal interaction is particularly strong. Singlewall carbon nanotubes exhibit significant self-heating, showing negative differential conductance, light emission and ultimately burning in air at high bias. Phase-change memory must, by design, have high and localized power density during operation, since the state of the bit is altered thermally. Simple experiments are used to gain new insight into the Fundamental behavior of both device types. This work suggests much room for the optimization of nanoscale devices through geometry, interface and materials design. Location: Olin Hall (OHE) 122

Transition Matrix Methods
Mon, Jun 25, 2007 @ 11:00 AM - 12:00 PM
Ming Hsieh Department of Electrical and Computer Engineering
Conferences, Lectures, & Seminars
SPEAKER: Professor David Yevick, Department of Physics, University of WaterlooABSTRACT: The transition matrix contains the probabilities that a system will
evolve between any two sets of states in a given time interval. In this
presentation, we demonstrate that techniques similar to the
multicanonical method can be employed to find the elements of the
transition matrix between pairs of rarely occurring states in an optical
communication system. This result is then applied to determine the
probability distribution of outage times resulting from polarization
mode delay (PMD).BIO: David Yevick was born in New York City on May 3, 1954. He received the A B. degree in physics from Harvard University, Cambridge, MA, in 1974,
the M A. and Ph D degrees in physics from Princeton University,
Princeton, NJ, in 1975 and 1977, respectively.Dr. Yevick is a professor at the University of Waterloo, Waterloo, ON,
Canada. He has written more than 160 papers involving the application of
numerical and analytic procedures to optical fibers, integrated optics,
and semiconductor laser modeling and, more recently, optical
communication system analysis. Dr. Yevick is a Fellow of the Optical Society of America (OSA), the IEEE and the American Physical Society (APS).Host: Alan Willner, willner@usc.edu
