Fret Studies Of Dna Binding By Lambda Cro Variants, Lei Wang Jan 2012

Fret Studies Of Dna Binding By Lambda Cro Variants, Lei Wang

Electronic Theses and Dissertations

Proteins bind to DNA to form switches and circuits that control the flow of genetic information from DNA sequence to the physical components of cells and organisms. The dynamic performance of genetic switches depends on the coupling of the comprocesses of transcription and translation to protein-specific folding, assembly and binding reactions. For many model circuits protein dimerization and DNA binding are fast relative to the time scale of transcription and translation and thus amenable to modeling by statistical thermodynamics. In these cases, the distribution of proteins between monomers and dimers and between nonspecific and specific DNA complexes can be simply …

Restricting Supervised Learning: Feature Selection And Feature Space Partition, Xiaofei Nan Jan 2012

Restricting Supervised Learning: Feature Selection And Feature Space Partition, Xiaofei Nan

Electronic Theses and Dissertations

Many supervised learning problems are considered difficult to solve either because of the redundant features or because of the structural complexity of the generative function. Redundant features increase the learning noise and therefore decrease the prediction performance. Additionally, a number of problems in various applications such as bioinformatics or image processing, whose data are sampled in a high dimensional space, suffer the curse of dimensionality, and there are not enough observations to obtain good estimates. Therefore, it is necessary to reduce such features under consideration. Another issue of supervised learning is caused by the complexity of an unknown generative model. …

Description Of Coherent Structures In The Atmospheric Boundary Layer By Model Reduction Of The Surface Pressure, Gregory William Lyons Jan 2012

Description Of Coherent Structures In The Atmospheric Boundary Layer By Model Reduction Of The Surface Pressure, Gregory William Lyons

Electronic Theses and Dissertations

The flow of coherent turbulent structures into a wind turbine is associated with vibrational blade excitation. Successful forecasting of such turbulent events for control system input would increase the lifetime of turbine components. The coherence of these features suggests description by model reduction. To this end, an array of pressure transducers was deployed on the ground at Reese Technology Center in Lubbock, Texas, and the pressure fluctuations were recorded over nearly two diurnal cycles. A program for computation of the dynamic mode decomposition was developed with special consideration for the case of a non-stationary, nonlinear system. A simulated surface-pressure perturbation …

Distributed Space-Time Message Relaying For Uncoded/Coded Wireless Cooperative Communications, Peng Huo Jan 2012

Distributed Space-Time Message Relaying For Uncoded/Coded Wireless Cooperative Communications, Peng Huo

Electronic Theses and Dissertations

During wireless communications, nodes can overhear other transmissions through the wireless medium, suggested by the broadcast nature of plane wave propagation, and may help to provide extra observations of the source signals to the destination. Modern research in wireless communications pays more attention to these extra observations which were formerly neglected within networks. Cooperative communication processes this abundant information existing at the surrounding nodes and retransmits towards the destination in various forms to create spatial and/or coding diversity, thereby to obtain higher throughput and reliability. The aim of this work is to design cooperative communication systems with distributed space-time block …

Virtual Worlds And Conservational Channel Evolution And Pollutant Transport Systems (Concepts), Chenchutta Denaye Jackson

Electronic Theses and Dissertations

Many models exist that predict channel morphology. Channel morphology is defined as the change in geometric parameters of a river. Channel morphology is affected by many factors. Some of these factors are caused either by man or by nature. To combat the adverse effects that man and nature may cause to a water system, scientists and engineers develop stream rehabilitation plans. Stream rehabilitation as defined by Shields et al., states that "restoration is the return from a degraded ecosystem back to a close approximation of its remaining natural potential" [Shields et al., 2003]. Engineers construct plans that will restore streams …

Chinese/Chinese American Students At The University Of Mississippi From 1946 To 1975, Hsin-Yi Sandy Kao

Electronic Theses and Dissertations

The historical integration of the University of Mississippi (UM) brought both national and local attention when James Meredith was escorted by U.S. Marshals to enroll and attend classes on October 1, 1962 (Cohodas, 1997; Doyle, 2001; Eagles, 2009). Since the integration of UM, racial issues and efforts to promote racial reconciliation primarily have been defined in binary terms of Black and White. In this way, few people hardly noticed that a small number of Chinese/Chinese American students were actually attending UM prior to the historic integration by Meredith, a circumstance present in other southern universities that led historian Peter Wallenstein …

The Role Of Emotional Expression On Person Identity Recognition, Kristen Paris Jan 2012

The Role Of Emotional Expression On Person Identity Recognition, Kristen Paris

Electronic Theses and Dissertations

Facial information concerning person identity and emotional expression is vital to human social interaction, and therefore, we find it beneficial to remember the faces we see. Little is known, however, about whether emotional expressions facilitate or inhibit recognition for person identity. The present studies examined the role of emotional expression on person identity recognition by manipulating whether such information was presented at encoding (i.e., initial perception of the actor) or at recognition (i.e., later memory for the actor). In Experiment 1, participants recognized more actors displaying an angry rather than a happy expression, when they initially saw actors display a …
