Fluorescence images from human H4 neurogliomal cells exposed to different concentrations of CuO nanoparticles were collected by a high content fluorescence microscopy. A fully automated fluorescent cellular image analysis system has been developed for the consequential image analysis for cell viability. A data-driven background algorithm was used as adaptive multiple thresholding algorithm to categorize the cells into three classes: bright cells, dark cells, and background. Our image analysis approach includes: (1) the scale-space theory, namely Gaussian filtering with proper scale has been applied to the acquired images to generate local intensity maxima within each cell; (2) a novel method for defining local image intensity maxima based on the gradient vector field has been developed; and (3) a statistical model was proposed to overcome the problem of cell segmentation. Our data have shown that the automated image analysis protocol can achieve 90% success rate of cell detection compared to manual procedure. Cellular image analysis further indicated that H4 neuroglioma cells had a dose-dependent toxic response to the insult of CuO nanoparticles.","PeriodicalId":274010,"journal":{"name":"2007 IEEE International Symposium on Circuits and Systems","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131637984","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This filter utilizes an integrated resonant tank comprised of an on-chip transformer along with parasitic and designed capacitors. The design incorporates a novel method of controlled positive feedback via the integrated transformer and a single transistor, providing an adjustable quality factor for the inherently lossy on-chip resonator. The circuit transformer feedback and the unique Q-enhancement technique facilitate increased voltage swing across the resonator and subsequent linearity improvement. The filter has a measured center frequency, fo, of 2.14 GHz, a maximum gain of 5 dB (~10dB unbuffered), and a tunable Q of 3 to 29. With the filter adjusted for the maximum quality factor and gain, the input compression point, P1dB, is measured at -3.5 dBm with a power dissipation of 143.1 mW and a measured input referred noise power of -144.3 dBm at a spot bandwidth of 1 Hz. As a prospective Bluetooth receiver input stage, dynamic range is measured at 59.6 dB and 80.8 dB over the filter operational and channel bandwidths of 132 MHz (84timespi/2 MHz) and 1 MHz.","PeriodicalId":274010,"journal":{"name":"2007 IEEE International Symposium on Circuits and Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131073383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
