  • Publication number: 20120195400
    Abstract: A method and system for estimating and compensating for variation between a receiver clock and a transmitter clock, where a receiver utilizes a high frequency clock signal to generate a receiver clock and then adjusts the receiver clock to compensate for variations between the receiver and transmitter clocks. The adjusted receiver clock is used to sample nibble pulses in a received data frame. Counter based compensation of the receiver clock eliminates the need for the receiver to perform floating point calculations, improves the accuracy of nibble pulse sampling and also reduces area and power consumption of the device.

  • Publication number: 20120190708
    Abstract: The emergence of multidrug-resistant pathogens necessitates the search for new antibiotics acting on previously unexplored targets. Nicotinate mononucleotide adenylyltransferase of the NadD family, an essential enzyme of NAD biosynthesis in most bacteria, was selected as a target for structure-based inhibitor development. To this end, the inventors have identified small molecule compounds that inhibit bacterial target enzymes by interacting with a novel inhibitory binding site on the enzyme while having no effect on functionally equivalent human enzymes.

  • Patent number: 8222673
    Abstract: A low energy surface is formed by a high temperature anneal of the surfaces of trenches on each side of a gate stack. The material of the semiconductor layer reflows during the high temperature anneal such that the low energy surface is a crystallographic surface that is at a non-orthogonal angle with the surface normal of the semiconductor layer. A lattice mismatched semiconductor material is selectively grown on the semiconductor layer to fill the trenches, thereby forming embedded lattice mismatched semiconductor material portions in source and drain regions of a transistor. The embedded lattice mismatched semiconductor material portions can be in-situ doped without increasing punch-through. Alternately, a combination of intrinsic selective epitaxy and ion implantation can be employed to form deep source and drain regions.
