A comparative study of lowpass continuous-time delta-sigma modulators with pulse-shaped DACs

Creator:: Fang, Jie
Abstract:: Recently, continuous-time ΔΣ modulators are appearing increasingly often in both the literature and the marketplace due to their features of inherent antialiasing and relaxed requirements for opamp and so on. However, several nonideal factors such as clock jitter, excess loop delay, inter-symbol interference and so on, degrade the SNR performance...

Formation and modification of enduracididine, a nonproteinogenic amino acid

Creator:: Tan, Ying
Abstract:: Molecular genetic and enzymological techniques have been employed to study antibiotic biosynthesis. In this thesis, we studied the formation and modification of the nonproteinogenic amino acid enduracididine (End), which exists in two important antibiotics, mannopeptimycins (MPPs) and enduracidin. Sequence analysis of the MPP gene cluster revealed that the product of...

Translation of dengue virus RNA : influence of the untranslated regions on 5´-cap dependent translation and ribosome scanning

Creator:: Chiu, Wei-Wei
Abstract:: In this thesis, I studied the translation of dengue virus RNA using a luciferase reporter gene system in Vero cells. The dengue reporter mRNA construct, which harbors 5´-terminal viral nts and 3´-terminal nts, could be translated efficiently compared to an alpha globin reporter construct. The 5´-cap structure and 3´-untranslated region...

Fingerprinting and genetic stability of Rubus using molecular markers

Creator:: Castillo, Nina Rosa F.
Abstract:: Two studies used DNA markers to assess their usefulness in germplasm identification and evaluation of genetic stability in four cryopreserved Rubus accessions that were stored for over 10 years in liquid nitrogen. In the first study, 12 robust Simple Sequence Repeat (SSR) markers were developed from two microsatellite-enriched libraries of...

Development of a hybrid modeling framework for intensively managed Douglas-fir plantations in the Pacific Northwest

Creator:: Weiskittel, Aaron R.
Abstract:: Forest growth models in the Pacific Northwest are predominantly empirical. Predictions of yield under alternative silvicultural regimes cannot rely completely on field trials; yet empirical growth models are often inadequate for extrapolating untested regimes and genotypes. The limitations of current models include (1) long time-steps (e.g. 5-10 years); (2) insufficient...

Low-voltage data converters

Creator:: Meng, Qingdong
Abstract:: With the growing demand for portable/consumer electronics, such as digital audio/video (AV), the downscaling of device dimensions, which enables the integration of an increasing number of transistors in a single chip, is mandatory. This trend also continuously pushes the power supply voltage down to reduce the power consumption and improve...

A wideband low-power continuous-time delta-sigma modulator for next generation wireless applications

Creator:: Chen, Xuefeng
Abstract:: Delta-Sigma (ΔΣ) analog-to-digital converters (ADCs) are widely used in wireless transceivers. Recently, continuous-time (CT) ΔΣ ADCs gain growing interest in wireless applications for their lower power consumption and wider input bandwidth as compared with the discrete-time (DT) counterparts. In this thesis, a wideband low-power CT ΔΣ modulator for next generation...

Exploring the cellular mechanisms of Cnidarian bleaching in the sea anemone Aiptasia pallida

Creator:: Perez, Santiago
Abstract:: Many members of the Phylum Cnidaria are mutualistic with unicellular dinoflagellates belonging to the genus Symbiodinium. Corals are the most widely recognized example of these associations due to their key ecological importance in coral reef ecosystems where they serve as the structural and trophic foundation of these rich ecosystems. Coral...

Molecular investigation of the cnidarian-dinoflagellate symbiosis and the identification of genes differentially expressed during bleaching in the coral Montipora capitata

Creator:: Hauck, Laura L.
Abstract:: Cnidarians, such as anemones and corals, engage in an intracellular symbiosis with photosynthetic dinoflagellates. Corals form both the trophic and structural foundation of reef ecosystems. Despite their environmental importance, little is known about the molecular basis of this symbiosis. In this dissertation we explored the cnidariandinoflagellate symbiosis from two perspectives:...

Development of solution-based reaction processes for micro- and nano-structured semiconductors

Creator:: Lee, Doo-Hyoung
Abstract:: The focus of this study is to develop a general and low-cost solution-based process to fabricate micro- and nano-structured semiconductors that are suitable for electronics. This process uses simple metal halide precursors dissolved in a solvent (organic or aqueous) and is capable of forming uniform and continuous thin films via...
