摘要： A negative dielectric is induced by the application of a dc bias-electric field in aggregates of oxide nano-particles whose surfaces have been specially treated. The magnitude of the dielectric constant and the frequency where the negative dielectric constant occurs can be adjusted. Such material systems have profound implications in novel devices as well as in science development, e.g. unusual wave propagation, secured communication and ultra-high temperature superconductivity.

摘要： In one embodiment, a dielectric layer (144, 156) overlying a semiconductor substrate (28) is uniformly polished. During polishing, the perimeter (32) of the semiconductor substrate (28) overlies a peripheral region (16, 48, 66, 86, 120) of a polishing pad (6, 42, 60, 80, 100) and an edge portion (36) of the front surface of semiconductor substrate (28) is not in contact with the front surface (18, 50, 68, 88, 122) of the polishing pad (6, 42, 60, 80, 100), in the peripheral region (16, 48, 66, 86, 120). As a result, the polishing rate at the edge portion (36) of the semiconductor substrate (28) is reduced, and the semiconductor substrate (28) is polished with improved center to edge uniformity. Since the semiconductor substrate (28) is polished with improved center to edge uniformity, die yield is increased because die located within the edge portion (36) of the semiconductor substrate (28) are not over polished.

摘要： A first periodic voltage waveform (20) is downconverted into a second periodic voltage waveform (35, 36). A plurality of temporally distinct samples (SA1, SA2, . . . ) respectively indicative of areas under corresponding half-cycles of the first voltage waveform are obtained. The samples are combined to produce the second voltage waveform, and are also manipulated to implement a filtering operation such that the second voltage waveform represents a downconverted, filtered version of the first voltage waveform.

摘要： A method for producing the high-value ketocarotenoid astaxanthin by the green microalga Chlorella zofingiensis in dark-heterotrophic cultures shows excellent growth and high-yield astaxanthin production on glucose-supplemented media in the dark. The specific growth rate and astaxanthin yield can be as high as 0.031 h−1, and 10.3 mg l−1, respectively, which are the highest so far reported in heterotrophic algal cultures. The light-independent astaxanthin-producing ability of Chlorella zofingiensis can be employed for commercial production of astaxanthin using industrial fermenters.

摘要： A digital-to-analog converter (DAC) error suppression arrangement suppresses DAC error arising from mismatched elements contained in a DAC (640 and/or 645) that is part of a modulator (FIG. 6). A low pass averaging (LPA) index decoder 650 controls a shifting arrangement 635 to shift a digital word T2 derived from modulator output Y so that the DAC error distribution constitutes a low pass profile (FIG. 5). Thus, DAC error is suppressed at higher frequencies (close to half the sampling rate), thereby providing improved spurious free dynamic range (SFDR). The LPA index decoder 650 causes the shifting arrangement 635 to shift the digital word T2 using only a single pointer per clock cycle.
