Abstract: Gene expression can be quantitatively analyzed by hybridizing fluor-tagged mRNA to targets on a cDNA micro-array. Comparison of gene expression levels arising from co-hybridized samples is achieved by taking ratios of average expression levels for individual genes. In an image-processing phase, a method of image segmentation identifies cDNA target sites in a cDNA micro-array image. The resulting cDNA target sites are analyzed based on a hypothesis test and confidence interval to quantify the significance of observed differences in expression ratios. In particular, the probability density of the ratio and the maximum-likelihood estimator for the distribution are derived, and an iterative procedure for signal calibration is developed.

Abstract: A control circuit, system for, and method of, testing a device under test (DUT) coupled to a load having a controllable load current level. The DUT is capable of operating in a regulated range and an unregulated range. In one embodiment, the control circuit includes: (1) minimum and maximum current control stages that set minimum and maximum load current values, respectively, for the control circuit and (2) an integrator, coupled to the DUT. In a constant current mode, the integrator selects one of the minimum and maximum load current values to control the load current level and test the DUT while the DUT is operating in the regulated range. In a constant voltage mode, the integrator produces an intermediate load current value based on a relationship between a voltage of an output of the DUT and a reference voltage to control the load current level and test the DUT while the DUT is operating in the unregulated range.

Abstract: An improved intraocular lens and related method of production are provided, wherein resilient drawn haptics are formed integrally with a lens body for supporting the lens body at a centered position with a patient's eye. A lens preform is constructed from a selected polymeric material to include the lens body having integrally formed lobes at selected points on the periphery thereof. The lobes are then drawn outwardly under elevated temperature conditions and set with a selected curvature to form resilient, substantially filamentary haptics or support loops of a desired shape. Such drawing of the polymeric material results in substantial alignment of polymers longitudianlly along the haptics such that the haptics exhibit a combination of significant resiliency and high structural strength.
