  • Patent number: 9062305
    Abstract: Described and claimed herein are combinatorial synthetic Fab libraries displayed on a phage pIX protein. The libraries were built on scaffolds representing the most frequently used genes in human antibodies, which were diversified to mirror the variability of natural antibodies. After selection using a diverse panel of proteins, numerous specific and high-affinity Fabs were isolated. By a process called in-line maturation the affinity of some antibodies was improved up to one hundred-fold yielding low pM binders suitable for in vivo use. This work thus demonstrates the feasibility of displaying complex Fab libraries as pIX-fusion proteins for antibody discovery and lays the foundations for studies on the structure-function relationship of antibodies.

  • Patent number: 8977993
    Abstract: An integrated circuit design optimization procedure to modify a cell feature, such as gate length, models changes in delay as a result of the modification. In the delay change calculation, a characteristic of an event in cell switching behavior, such as the output short-circuit voltage VSC, is determined for the modified cell, where changes in the determined characteristic correlate with changes in delay of the cell due to the modification. Next, a value for delay of the modified cell is determined as a function of the determined characteristic of the event. The procedure can be applied after placement and routing. A timing-constrained, leakage power reduction is described using the delay change model.

  • Patent number: 8958646
    Abstract: An image processing device combines a plurality of contents (e.g. videos) with a story line retained as much as possible, while reducing view's discomfort. The image processing device compares one of the contents, which contains a first partial content and a second partial content subsequent to the first partial content, with another one of the contents, which contains a plurality of consecutive partial contents; detects, as a third partial content, a partial content with the highest similarity value from among the plurality of partial contents; and generates relational information by using the highest similarity value obtained by the first processing unit. The relational information is then used for merging the first partial content, the second partial content and the third partial content.
