Isolation And Functional Characterization Of Two Rapeseed Genes Orthologous To Arabidopsis Thaliana Phenylalanine Ammonia-Lyase 2, Yu Ni, Yan-Zhen Dong, Guan-Rong Li, Bo Lei, You-Rong Chai, Jia-Na Li

Turkish Journal of Agriculture and Forestry

Two rapeseed (Brassica napus L.) phenylalanine ammonia-lyase 2 genes (BnPAL2-1 and BnPAL2-2) were isolated. The full-length cDNAs of BnPAL2-1 and BnPAL2-2 are 2422 bp and 2421 bp, with corresponding genomic sequences of 2735 bp and 2742 bp, respectively. Clues from NCBI BLAST, multi-alignment, the phylogenetic tree, conserved domains, preferential amino acids, and tertiary structures all indicated that they are orthologs of Arabidopsis thaliana PAL2 (AtPAL2). The purified His-tagged BnPAL2-1 and BnPAL2-2 proteins, expressed in Escherichia coli, were both active for PAL catabolism, but BnPAL2-2 was much more active than BnPAL2-1. Southern blot analysis showed that the BnPAL2 subfamily might contain …

Genetic Analysis Of Some Physical Properties Of Bread Wheat Grain (Triticum Aestivum L. Em Thell), Cemal Yücel, Faheem Shehzad Baloch, Hakan Özkan

Turkish Journal of Agriculture and Forestry

Very little information exists on the relative genetic architecture of the grain physical properties of wheat. The physical properties of grain have a direct or indirect influence on the milling and baking quality of wheat. Therefore, understanding the inheritance of grain physical properties will be useful to improve varieties with better quality. Five bread wheat cultivars were crossed in order to evaluate the mode of inheritance and combining ability and the correlation of the grain's physical properties. Analysis of variance for combining ability showed that both additive and non-additive gene actions were involved in controlling most of the traits. Magnitudes …

Detection Of Low Cost Radio Frequency Receivers Based On Their Unintended Electromagnetic Emissions And An Active Stimulation, Sarah A. Seguin

Doctoral Dissertations

"Detection of super-regenerative receivers using their unintended electromagnetic emissions at a significant distance is challenging due to high levels of ambient noise. The evolution of an approach used to solve this problem is chronicled within the three papers that combine to form this dissertation. First, a passive detection method was created for detecting devices based on the characterization of their unintended emissions and utilized a cascading correlation method to confirm detection. Using a simple sine-wave stimulation to modify these unintended emissions produced better results over passive detection techniques by improving the signal quality and the consistency of the unintended emissions, …

The Sec And The Madoff Scandal: Three Narratives In Search Of A Story, Donald C. Langevoort

Georgetown Law Faculty Publications and Other Works

This essay, part of a symposium on narrative in corporate law, considers various portrayals of the complicity of the SEC in the Bernard Madoff scandal--including the Commission's own Inspector General's report issued in September 2009. It considers possible explanations (revolving door problems, incompetence and sloth, etc.) but suggests that the story is deeper and more frustrating, arising out of the relative poverty in which the SEC operates, which in turn leads to habits of thought and action that leave too much unnoticed and undone. The interesting question, then: why the poverty? The essay concludes with a political explanation. While by …

Self-Realizing Inventions And The Utilitarian Foundation Of Patent Law, Alan J. Devlin, Neel U. Sukhatme

Georgetown Law Faculty Publications and Other Works

Unlike other forms of intellectual property, patents are universally justified on utilitarian grounds alone. Valuable inventions and discoveries, bearing the characteristics of public goods, are easily appropriated by third parties. Because much technological innovation occurs pursuant to significant expenditures—both in terms of upfront research and subsequent commercialization costs—inventors must be permitted to extract at least part of the social gain associated with their technological contributions. Absent some form of proprietary control or alternative reward system, economics predicts that suboptimal capital will be devoted to the innovative process.

This widely accepted principle comes with an important corollary: namely, that canons of …

3d Reconstruction Using Multi-View Imaging System, Conglin Huang

University of Kentucky Master's Theses

This thesis presents a new system that reconstructs the 3D representation of dental casts. To maintain the integrity of the 3D representation, a standard model is built to cover the blind spots that the camera cannot reach. The standard model is obtained by scanning a real human mouth model with a laser scanner. Then the model is simplified by an algorithm which is based on iterative contraction of vertex pairs. The simplified standard model uses a local parametrization method to obtain the curvature information. The system uses a digital camera and a square tube mirror in front of the camera …

Mpi Within A Gpu, Bobby Dalton Young

University of Kentucky Master's Theses

GPUs offer high-performance floating-point computation at commodity prices, but their usage is hindered by programming models which expose the user to irregularities in the current shared-memory environments and require learning new interfaces and semantics.

This thesis will demonstrate that the message-passing paradigm can be conceptually cleaner than the current data-parallel models for programming GPUs because it can hide the quirks of current GPU shared-memory environments, as well as GPU-specific features, behind a well-established and well-understood interface. This will be shown by demonstrating a proof-of-concept MPI implementation which provides cleaner, simpler code with a reasonable performance cost. This thesis will also …

Iterative Methods For Computing Eigenvalues And Exponentials Of Large Matrices, Ping Zhang

University of Kentucky Doctoral Dissertations

In this dissertation, we study iterative methods for computing eigenvalues and exponentials of large matrices. These types of computational problems arise in a large number of applications, including mathematical models in economics, physical and biological processes. Although numerical methods for computing eigenvalues and matrix exponentials have been well studied in the literature, there is a lack of analysis in inexact iterative methods for eigenvalue computation and certain variants of the Krylov subspace methods for approximating the matrix exponentials. In this work, we proposed an inexact inverse subspace iteration method that generalizes the inexact inverse iteration for computing multiple and clustered …

Direct Electron-Beam Patterning Of Teflon-Af And Its Application To Optical Waveguiding, Vijayasree Karre

University of Kentucky Master's Theses

Thin films of Teflon AF have been directly patterned by electron-beam lithography without the need for post exposure chemical development. The relationship between pattern depth and exposure dose was found to be linear over a wide range of doses. Pattern depth was also observed to be dependent on initial film thickness. Teflon AF can be directly patterned at doses similar to typical e-beam resists. High resolution features as small as ~200 nm have been resolved. FTIR measurements revealed that CF3 and fluorinated dioxole groups play a significant role in the patterning mechanism. Teflon AF films also exhibited an increase in …

Collective Communication And Barrier Synchronization On Nvidia Cuda Gpu, Diego Alejandro Rivera-Polanco

University of Kentucky Master's Theses

GPUs (Graphics Processing Units) employ a multi-threaded execution model using multiple SIMD cores. Compared to use of a single SIMD engine, this architecture can scale to more processing elements. However, GPUs sacrifice the timing properties which made barrier synchronization implicit and collective communication operations fast.

This thesis demonstrates efficient methods by which these aggregate functions can be implemented using unmodified NVIDIA CUDA GPUs. Although NVIDIA's highest “compute capability" GPUs provide atomic memory functions, they have order N execution time. In contrast, the methods proposed here take advantage of basic properties of the GPU architecture to make implementations that are both …

General Formulation Of The Scattered Matter Waves By A Quantum Shutter, Yusuf Zi̇ya Umul

Turkish Journal of Physics

The scattering process of matter waves by a quantum shutter is investigated by using the spectrum integral representation. The scattered fields are expressed in terms of the Fresnel function. It is shown that the obtained equation gives the Moshinsky function for a one dimensional problem of the plane wave. Also a general integral representation is derived for two dimensional problems. The scattering of matter waves for some special wave-packets are examined analytically and numerically.

Superconducting State Parameters Of Al-Li Binary Alloys, Aditya M. Vora

Turkish Journal of Physics

Theoretical computation of superconducting state parameters (SSP) viz. electron-phonon coupling strength \lambda , Coulomb pseudopotential \mu^* , transition temperature T_C , isotope effect exponent \alpha and effective interaction strength N_o V of face centered cubic Al_{1-C} Li_C binary alloys have been made extensively in the present work using a model potential formalism for the first time. A considerable influence of various exchange and correlation functions on \lambda and \mu^* is found from the present study. The present results of the SSP are found in qualitative agreement with the available experimental data wherever exist.
