Prediction Of Timing Signals In Financial Series Using Neural Networks, Asheesh Mehta

LSU Historical Dissertations and Theses

The stock markets represent a complex system of inter-related factors that are difficult to model using conventional statistical techniques. Forecasting stock market trends is a challenging and rewarding task. This has led to extensive research into stock market behavior and the development of analytical and artificial intelligence tools for stock trading. The most promising application of artificial intelligence in finance is the use of neural networks. This thesis is concerned with the application of neural networks for the generation of stock market timing signals.

We have examined different analytical approaches to stock market trading. For the generation of trading signals, …

Ka'o'Ob: The Metates Of Chichen Itza Within The Context Of The Greater Maya Realm, Bryan Luter Anderson

LSU Historical Dissertations and Theses

Metates- maize grinding stones- from the Terminal Classic/Early Postclassic Maya site of Chichen Itza, Yucatan, Mexico are analyzed with respect to both intra-site dynamics and in relation to the greater Maya realm. Two hundred and seven metates or portions of metates were recorded in survey and mapping activities and from site storage. These metates are examined with a focus on size, material, form, and distribution. Results of the research are used to show how the inhabitants of Chichen Itza adapted to a native environment ill-suited for metate manufacture, and how this adaptation led to a metate industry significantly different from …

Differential Display: Identifying Genes Involved In Cardiomyocyte Proliferation, Stephania Cormier-Regard, Daniel B. Egeland, Vivien J. Tannoch, William C. Claycomb

Division of Basic Science Faculty Publications

An estimated 15,000 different mRNA species are expressed in a typical mammalian cell. The differential expression of mRNAs in both a temporal and cell-specific manner determines the fate of the cell and creates the organism. Analysis of this differential gene expression has become a central aim of many laboratories attempting to understand the mechanisms underlying various biological processes. Currently, we are using a technique called differential display to analyze the differential expression of genes in cardiomyocytes. Differential display is a rapid and powerful technique that was introduced by Liang and Pardee in 1992. Since that time, it has been successfully …

Effect Of Naturally Occurring Bromophenols On Sulfate Reduction And Ammonia Oxidation In Intertidal Sediments, C. Giray, G. M. King

Faculty Publications

We examined the effect on ammonium oxidation and sulfate reduction of several brominated compounds [4-bromophenol, 2,4-dibromophenol (2,4-DBP), 2,6-dibromophenol and 2,4,6-tribromophenol] that occur naturally in enteropneusts. We compared rates of these processes with and without bromoorganics using bulk intertidal sediments and burrow wall sediments from 3 enteropneust species (2 containing 2,4-DBP and 1 containing 2,3,4-tribromopyrrole), a mollusc (Mya arenaria) and a polychaete (Nereis virens). Sulfate reduction in bulk sediment was unaffected by bromophenols at concentrations sediment, but was inhibited temporarily at 1 μmol cm-3. Sulfate reduction in burrow wall sediments differed from bulk sediments, but was not correlated with concentrations of …

Identification And Characterization Of Two Polymorphic Ya5 Alu Repeats, Santosh S. Arcot, Margaret M. Deangelis, Stephen T. Sherry, Aaron W. Adamson, Jane E. Lamerdin, Prescott L. Deininger, Anthony V. Carrano, Mark A. Batzer

Faculty Publications

Two new polymorphic Alu elements (HS2.25 and HS4.14) belonging to the young (Ya5/8) subfamily of human-specific Alu repeats have been identified. DNA sequence analysis of both Alu repeats revealed that each Alu repeat had a long 3'-oligo-dA-rich tail (41 and 52 nucleotides in length) and a low level of random mutations. HS2.25 and HS4.14 were flanked by short precise direct repeats of 8 and 14 nucleotides in length, respectively. HS2.25 was located on human chromosome 13, and HS4.14 on chromosome 1. Both Alu elements were absent from the orthologous positions within the genomes of non-human primates, and were highly polymorphic …

Interaction Between Calf Sex And Calf Genetic Type For Preweaning Traits Of Calves Varying In Percentage Brahman Breeding, F. A. Thrift, S. M. Clark, D. K. Aaron, D. E. Franke

Faculty Publications

Two data sets were utilized to evaluate interaction between calf sex and calf genetic type for preweaning performance of calves varying in percentage (0, 50, 100) Brahman breeding. Data set I involved birth weight, preweaning average daily gain, and weaning weight records on 3562 Angus (AA), Brahman ♂ × Angus ♀ (BA) and Brahman (BB) calves; data set II consisted of birth weight, preweaning average daily gain and weaning weight records on 3752 Hereford (HH), Brahman ♂ × Hereford ♀ (BH) and Brahman (BB) calves. For both data sets, the calf sex × calf genetic type interaction was significant (P<0.01) except for preweaning average daily gain in data set II. In all cases, the significant interactions were represented by a change in magnitude rather than a change in rank for the two sexes of each calf genetic type. These results indicate that sex differences are expected to be much greater for Brahman-sired BA and BH calves than for calves of 0% (AA or HH) or 100% (BB) Brahman breeding. These increased sex differences are of greatest importance for birth weight because of the relationship that exists between birth weight and calving difficulty.

Bis[(Anhydro-Meso-Rhodochlorinato-Xv Methyl Ester)Zinc(Ii)], Mathias O. Senge, Kevin M. Smith

Faculty Publications

The title compound, bis[(methyl 8,13-diethyl-2,21,22,2 3-tetrahydro-3,7,12,17-tetramethyl-2 3-oxo-3H-benzo[at]-porphyrin-18-carboxylato-κ4N) zinc (II)], [Zn(C33H34-N4O3)]2, has similar structural characteristics to the naturally occurring factor F430 and forms dimers that are held together by axial interactions between the zinc(II) center and the cyclohexanone carbonyl O atom of a neighboring macrocycle [Zn - O3 2.204 (3) Å]. These dimers form infinite stacks in the crystal stabilized by π-π interactions between the aromatic ring systems.

Hypertension In Blacks, R. Cooper, C. Rotimi

Faculty Publications

The excess of hypertension among blacks has been recognized since early in this century and explains a substantial portion of the black health disadvantage. In a cohort study begun in the 1970s, hypertension accounted for 20% of all-cause mortality among blacks, compared to 10% among whites. National data on trends in hypertension (140/90 mm Hg or treatment) prevalence from 1960 to 1990 suggest a decline from 44% to 32%, although differences in survey technique likely account for this pattern. During this period the prevalence ratio of black:white remained constant at 1.5, suggesting that secular trends in causal factors, if any, …

In Vivo Kinetics Of A Redox-Regulated Transcriptional Switch, Huangen Ding, Bruce Demple

Faculty Publications

SoxR is a transcription activator governing a cellular response to superoxide and nitric oxide in Escherichia coli. SoxR protein is a homodimer, and each monomer has a redox-active [2Fe-2S] cluster. Oxidation and reduction of the [2Fe-2S] clusters can reversibly activate and inactivate SoxR transcriptional activity. Here, we use electron paramagnetic resonance spectroscopy to follow the redox-switching process of SoxR protein in vivo. SoxR [2Fe-2S] clusters were in the fully reduced state during normal aerobic growth, but were completely oxidized after only 2-min aerobic exposure of the cells to superoxide-generating agents such as paraquat. The oxidized SoxR [2Fe-2S] clusters were rapidly …

Property Fields In An Effluent Plume Of The Mississippi River, G. L. Hitchcock, W. J. Wiseman, W. C. Boicourt, A. J. Mariano, N. Walker, T. A. Nelsen, E. Ryan

Faculty Publications

Surface property distributions were mapped in the Mississippi River plume during May and August, 1993 while following surface drifters. Prevailing winds were the primary factor controlling the orientation of the plume. In May, under typical southeasterly winds, the plume turned anticyclonically towards the coast, while in August, under anomalous westerly winds, the plume turned east. Remote imagery of sea surface temperature and suspended sediments confirmed the direction of the plume. Optimally interpolated maps of surface salinity, temperature, chlorophyll a fluorescence, and transmissivity from underway sampling, and periodic nutrient samples, reveal the plume structure. In May concentrations of nitrate, silicate, and …

Hall Effect In The Mixed State Of Moderately Clean Superconductors, I. Vekhter, A. Houghton

Faculty Publications

The Hall conductivity in the mixed state of a clean (l ≫ ξ0) type-II s-wave-superconductor is determined from a microscopic calculation within a quasiclassical approximation. We find that below the superconducting transition the contribution to the transverse conductivity due to dynamical fluctuations of the order parameter is compensated by the modification of the quasiparticle contribution. In this regime the nonlinear behaviour of the Hall angle is governed by the change in the effective quasiparticle scattering rate due to the reduction in the density of states at the Fermi level. The connection with experimental results is discussed.

Twin Hydroxymethyluracil-A Base Pair Steps Define The Binding Site For The Dna-Bending Protein Tf1, Anne Grove, Marxa L. Figueiredo, Aldo Galeone, Luciano Mayol, E. Peter Geiduschek

Faculty Publications

The DNA-bending protein TF1 is the Bacillus subtilis bacteriophage SPO1- encoded homolog of the bacterial HU proteins and the Escherichia coli integration host factor. We recently proposed that TF1, which binds with high affinity (K(d) was ~3 nM) to preferred sites within the hydroxymethyluracil (hmU)-containing phage genome, identifies its binding sites based on sequence-dependent DNA flexibility. Here, we show that two hmU-A base pair steps coinciding with two previously proposed sites of DNA distortion are critical for complex formation. The affinity of TF1 is reduced 10-fold when both of these hmU-A base pair steps are replaced with A-hmU, G-C, or …
