20090111061Methods of Minimizing Etch Undercut and Providing Clean Metal Liftoff - A method of minimizing etch undercut and providing clean metal liftoff in subsequent metal deposition is provided. In one embodiment a bilayer resist mask is employed and used for etching of underlying substrate material and subsequent metal liftoff. In one embodiment, the top layer resist such as positive photoresist which is sensitive to selected range of energy, such as near UV or violet light, is first patterned by standard photolithography techniques and resist development in a first developer to expose portion of a bottom resist layer which is sensitive to a different selected range of energy, such as deep UV light. The exposed portion of the bottom layer resist is then removed by anisotropic etching such as oxygen reactive ion etching using the top layer resist as the etch mask to expose portion of the underlying substrate. This minimizes the undercut in the bottom resist around the top photoresist opening. The resultant patterned bilayer resist stack is then used as the etch mask for the subsequent etching of the exposed portion of the underlying substrate material. Because there is no undercut in the bottom resist layer, the etch undercut in the substrate material is also minimized relative to the edges of the top photoresist opening.04-30-2009

20110013733VARIABLE GAIN CONTROL FOR HIGH SPEED RECEIVERS - A high speed receiver is provided using two parallel processing paths to enable rapid variable gain control. The parallel processing paths include a first processing path using a high resolution Discrete Fourier Transform (DFT), and a second processing path using a reduced DFT requiring fewer samples than the high resolution DFT.

As a result of the comparison of the Fourier transform of the initial sample with the predetermined threshold values, a gain determination block determines whether a requirement exists for gain ranging. If gain ranging is needed, the gain of the data signal is adjusted and the gain ranging process repeats.01-20-2011

20080200416Modulation of T cell signaling threshold and T cell sensitivity to antigens - MicroRNAs (miRNAs) are a diverse and abundant class of ˜22-nucleotide (nt) endogenous regulatory RNAs that play a variety of roles in animal cells by controlling gene expression at the posttranscriptional level. Increased miR-181a expression in mature T cells is shown to cause a marked increase in T cell activation and augments T cell sensitivity to peptide antigens. Moreover, T cell blasts with higher miR-181a expression become reactive to antagonists. The effects of miR-181a on antigen discrimination are in part achieved by dampening the expression of multiple negative regulators in the T cell receptor (TCR) signaling pathway, including PTPN22 and the dual specificity phosphatases DUSP5 and DUSP6. This results in a reduction in the TCR signaling threshold, thus quantitatively and qualitatively enhancing T cell sensitivity to antigens.08-21-2008
