Structural Basis For The Regulation Of A Conserved Tonb-Dependent Iron Transport System Via Cell-Surface Signaling In Gram-Negative Bacteria, Jaime Lea Jensen Jan 2017

Structural Basis For The Regulation Of A Conserved Tonb-Dependent Iron Transport System Via Cell-Surface Signaling In Gram-Negative Bacteria, Jaime Lea Jensen

Chemistry and Biochemistry

Cell-surface signaling (CSS) pathways are highly conserved systems in Gram-negative bacteria that allow the cell to efficiently respond to environmental stimuli through transcriptional regulation. Three distinct proteins are involved in this process: an outer membrane (OM) protein that senses the extracellular signal, an inner membrane (IM) sigma regulator protein that transmits the signal from the OM protein to the cytoplasm, and an extracytoplasmic function (ECF) sigma factor that initiates transcription of stimulus response genes. One such CSS pathway regulates bacterial iron acquisition- an essential process for bacterial survival and pathogenesis. Under iron-limited conditions, expression of the OM transporter is upregulated …

Selected Topics In Image Super-Resolution: Guided Image And Learning Representation, Wentian Zhou

Graduate Theses, Dissertations, and Problem Reports (ETD)

Obtaining high-resolution images is a fundamental challenge for many vision related tasks. It is highly desirable to develop effective and efficient super-resolution algorithms to enhance the spatial resolution of acquired images. However, estimating high-resolution images is an ill-posed problem where a large set of possible solutions exist. To make this inverse problem more tractable, it is often necessary to constrain the targeted high-resolution image with a priori information (i.e., in model-based approaches) or to assume the availability of additional training data (i.e., in learning-based approaches). In this dissertation, we propose to (i) use simultaneous-sparse-coding and machine learning techniques to incorporate …
