Abstract:
The present invention is directed to compositions and methods for a genetic system of detecting protein-protein interactions in a mammalian host cell. Two fusion proteins are made in the host cell. The first fusion protein contains a DNA binding domain which is fused to a so-called bait protein. The second fusion protein consists of a transcriptional activation domain fused to a so-called test protein. The DNA binding domain binds to an operator sequence which controls expression of one or more reporter genes. The transcriptional activation domain is recruited to the promoter through the functional interaction between the bait protein and the test protein. Subsequently the transcriptional activation domain interacts with the basal transcription machinery to activate expression of one or more reporter genes which can be identified and characterized. The individual compositions are useful for analyzing protein-protein interactions between known proteins and to isolate, clone and characterize unknown proteins. The individual compositions can be used to express the fusion proteins either transiently or stably. In addition, the present invention is directed to methods for screening for candidate bioactive agents that modulate the protein-protein interaction between a bait protein and a test protein and thus are useful for the identification of novel therapeutic drugs and the like.
Abstract:
An optical source uses feedback to maintain a substantially fixed spacing between adjacent wavelengths in a set of wavelengths in a wavelength comb output by the optical source. In particular, a set of light sources in the optical source provide optical signals having the set of wavelengths. Moreover, the optical signals are output at diffraction angles of an optical device in the optical source (such as an echelle grating), and optical detectors in the optical source determine optical metrics associated with the optical signals. Furthermore, control logic in the optical source provides control signals to the set of light sources based on the determined optical metrics.
Abstract:
Disclosed are methods, apparatuses, etc. for glucose sensor signal stability analysis. In certain example embodiments, a series of samples of at least one sensor signal that is responsive to a blood glucose level of a patient may be obtained. Based at least partly on the series of samples, at least one metric may be determined to assess an underlying trend of a change in responsiveness of the at least one sensor signal to the blood glucose level of the patient over time. A reliability of the at least one sensor signal to respond to the blood glucose level of the patient may be assessed based at least partly on the at least one metric assessing an underlying trend. Other example embodiments are disclosed herein.

Abstract:
An electrophoretic display device includes a common electrode, an electrophoresis layer, and pixel electrodes. The electrophoretic layer includes cavities, with each cavity arranged between one of the pixel electrodes and the common electrode, and comprises suspension fluid, first type charged particles, and second type charged particles. The first type charged particles and the second type charged particles are dispersed in the suspension fluid. Three cavities constitute a pixel unit. The first type charged particles and the second type charged particles in each of the three cavities constituting the pixel unit are one of red, green, and blue particles, and one of yellow, magenta, and cyan particles, respectively.

A method and apparatus are described for integrating dual gate oxide (DGO) transistor devices (50, 52) and core transistor devices (51, 53) on a single substrate (15) having a silicon germanium channel layer (21) in the PMOS device areas (112, 113), where each DGO transistor device (50, 52) includes a metal gate (25), an upper gate oxide region (60, 84) formed from a second, relatively higher high-k metal oxide layer (24), and a lower gate oxide region (58, 84) formed from a first relatively lower high-k layer (22), and where each core transistor device (51, 53) includes a metal gate (25) and a core gate dielectric layer (72, 98) formed from only the second, relatively higher high-k metal oxide layer (24).
Abstract:
Forming structures such as fins in a semiconductor layer according to a pattern formed by oxidizing a sidewall of a layer of oxidizable material. In one embodiment, source/drain pattern structures and a fin pattern structures are patterned in the oxidizable layer. The fin pattern structure is then masked from an oxidation process that grows oxide on the sidewalls of the channel pattern structure and the top surface of the source/drain pattern structures. The remaining oxidizable material of the channel pattern structure is subsequently removed leaving a hole between two portions of the oxide layer. These two portions are used in one embodiment as a mask for patterning the semiconductor layer to form two fins. This patterning also leaves the source/drain structures connected to the fins.
Abstract:
A semiconductor device has at least two tensile stressor layers that are cured with UV radiation. A second tensile stressor layer is formed after a first stressor layer. In some examples, the tensile stressor layers include silicon nitride and hydrogen. In some examples, the second tensile stressor layer has a greater shrinkage percentage due to the curing than the first tensile stressor layer. In one form, the second tensile stressor layer after the curing exerts a greater tensile stress than the first tensile stressor layer. The tensile stressors layers are utilized to improve carrier mobility in an N-channel transistor and thus enhance transistor performance. In one form a single group of overlying tensile stressor layers is provided with each layer being increasingly thicker and having increasingly more hydrogen prior to being cured. In other embodiments multiple overlying groups are formed, each group having a similar repeating depth and hydrogen profile.

Abstract:
A method for level three feature extraction from a print image extracts features associated with a selected ridge segment using a gray-level image under the guidance of at least one binary image. The level three features are a sequence of vectors each corresponding to a different level three characteristic and each representing a sequence of values at selected points on a print image. The level three features are stored and used for level three matching of two prints. During the matching stage, ridge segments are correlated against each other by shifting or a dynamic programming method to determine a measure of similarity between the print images.
