  2. Hierarchical Temporal Memory: How a New Theory of Neocortex May Lead to Truly Intelligent Machines

    12 Dec 2007 | | Contributor(s):: Jeff Hawkins

    Coaxing computers to perorm basic acts of perception and robotics, let alone high-level thought, has been difficult. No existing computer can recognize pictures, understand language, or navigate through a cluttered room with anywhere near a child's facility. Following nature's example, Jeff...

  3. KIST/PU Infrared and Raman Chemical Imaging of Pharmaceutical Biological Matter

    06 Dec 2007 | | Contributor(s):: Tom Tague

  5. Electrons in Two Dimensions: Quantum Corrals and Semiconductor Microstructures

    04 Dec 2007 | | Contributor(s):: Eric J. Heller

    The images generated by a scanning tunneling microscope are iconic. Some of the most famous are Don Eigler’s quantum corrals, which reveal not only the guest atoms on a surface but especially the interference patterns of electrons shuttling back and forth along the surface. To understand the...

  6. New Dimension in Performance: Harnessing 3D Integration Technology

    29 Nov 2007 | | Contributor(s):: Kerry Bernstein

    Despite generation on generation of scaling, computer chips have remained essentially 2-dimensional. Improvements in on-chip wire delay, and in the total number of inputs and outputs has not been able to keep up with improvements to the transistor, and its getting harder and harder to hide it! 3D...

  7. On the Rise of an Electronic Species: Thoughts on the Impending Singularity

    29 Nov 2007 | | Contributor(s):: Kerry Bernstein

    The human brain is vastly more complex that our best supercomputers; yet it can be argued that both systems evolve towards common underlying solutions to fundamental compute problems. Biologically-inspired electronic technologies already are enabling new products, and inversely, nano-electronics...

    06 Nov 2007 | | Contributor(s):: Kamil Walczak

    Molecular electronics faces many problems in practical device implementation, due to difficulties with fabrication and gate-ability. In these devices, molecules act as the main conducting channel. One could imagine alternate device structures where molecules act as quantum dots rather than...

  11. MCW07 Impact of Porphyrin Functional Groups on InAs Gas Sensors

    05 Nov 2007 | | Contributor(s):: Michael Garcia

    Porphyrin molecules are often used for sensor engineering to improve sensitivity and selectivity to specific analytes. It is important to understand how the porphyrin HOMO-LUMO levels deplete surface states during functionalization of solid state sensors. Additionally, the effect of...
