Tiger Rag

The University's first fight song was written to the music and lyrics of "Tiger Rag," the famous jazz ballad produced in 1917 by the New Orleans group Original Dixieland Jazz Band. Tiger Rag is used as a fight song by the Detroit Tigers baseball team, as well as by the Louisiana State University Tigers

Synthesis and Characterization of a Novel Fluorinated Bismaleimide via a Nucleophilic Addition-Elimination Reaction and its Polymeric Networks

Includes supplementary material.The commercially available octafluorocyclopentene (OFCP) as both a fluorinated building block and a linker has been successfully utilized to prepare a new fluorinated bismaleimide monomer OFCP-BMIvia a nucleophilic addition-elimination reaction. The resulting OFCP-BMI is characterized by 1H, 13C, 19F nuclear magnetic resonance (NMR) spectroscopy, attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), and high resolution mass spectrometry. The monomer OFCP-BMI reacts with a free radical initiator or self-cures to prepare its resins. No obvious glass transition temperature (Tg) below 260°C was observed for the self-curing resin suggesting that a highly cross-linked polymeric network was formed. The self-curing resin exhibits excellent thermal stability with the on-set weight loss temperature (Ton-setd) of 445°C and a 50% char yield at 800°C under a nitrogen atmosphere. The resin obtained by a free radical polymerization process exhibits less thermal stability and a lower char yield than the self-curing resin due to its lower cross-linking density. The self-curing resin exhibits a low dielectric constant (Dk = 2.5)

Search for New Phenomena in Final States with an Energetic Jet and Large Missing Transverse Momentum in pp Collisions at √s=8 TeV with the ATLAS Detector

Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb-1 of √S=8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with PT>120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between (Formula presened.)>150 GeV and (Formula presened.)>700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presented

Blue Light Emitting Electrochemical Cells Incorporating Triazole-based Luminophores

We report the electrochemical, photoluminescence, and electroluminescence properties of four fluorinated cationic iridium complexes bearing pyridyltriazole ancillary ligands. All the complexes display unstructured emission in the true blue region at 298 K with photoluminescent λem ranging from 452 to 487 nm in acetonitrile solution, in powder and in PMMA doped thin films. The nature of the emission is a mixed metal-to-ligand/ligand-to-ligand charge transfer state. Photoluminescence (PL) quantum efficiencies both in solution and in the solid state were low while excited state decay kinetics were found to be multiexponential. Each complex undergoes quasi-reversible oxidation and irreversible reduction with large HOMO-LUMO gaps. A detailed computational investigation corroborates the spectroscopic assignments. Additionally, light-emitting electrochemical cells (LEECs) were fabricated for each of the four complexes. The electroluminescence (EL) spectra of all complexes were red-shifted relative to the PL spectra. The LEEC containing 2a is the bluest emitter (λmax = 487 nm) of the family of complexes

Competition in consumer shopping experience

A subscription or fee may be necessary to view the article.This paper analyzes the competitive role of retail shopping experience in markets with consumer search costs. We examine how a retailer's advantage in providing consumer shopping experience affects its equilibrium pricing and price advertising strategies. We find that if the consumer valuation of a shopping experience is sufficiently low, its effect on retailer strategy is similar to that of quality, and the retailer with the advantage in shopping experience then deploys higher levels of price advertising. On the other hand, when the shopping experience is valuable enough for consumers, it acts akin to price advertising in that it makes it optimal for the retailer with the advantage in shopping experience to eschew price advertising. The optimal competitive investments in consumer shopping experience can be higher than that of a monopoly. The profit impact of shopping experience for a retailer depends on the level of shopping experience: for low levels, the profit impact depends on the difference in the levels between the retailers, but for high enough levels, it depends only on whether the retailer's shopping experience level is higher than that of its competitor. In this case, even small differences in shopping experience levels can result in large differences in equilibrium profits. © 2012 INFORMS.Finial published versio

Direct Detection of Tissue-Resident Bacteria and Chronic Inflammation in the Bladder Wall of Postmenopausal Women with Recurrent Urinary Tract Infection

Due to copyright restrictions full text access from Treasures at UT Dallas is restricted to current UTD affiliates (use the provided Link to Article).Includes supplementary informationUrinary tract infections (UTIs) are the most commonly reported infections in adult women and have high rates of recurrence, especially in postmenopausal women. Recurrent UTI (RUTI) greatly reduces quality of life, places a significant burden on the healthcare system, and contributes to antimicrobial resistance. Because treatment of RUTI by long-term antibiotic therapy is often ineffective or poorly tolerated in elderly women, new therapies must be developed. The molecular basis of RUTI, especially in postmenopausal women, has remained unclear because modeling RUTI in mice is difficult, and human data are limited. Invasion of the urothelium and induction of host inflammation are hypothesized to be key mechanisms by which bacterial pathogens cause RUTI. To further our understanding of RUTI in humans, we performed a systematic analysis of urine and bladder biopsy samples from postmenopausal women undergoing cystoscopy with fulguration of trigonitis in the advanced management of antibiotic-refractory RUTI. We provide direct evidence that bacteria reside in the bladder wall of postmenopausal RUTI patients and that diverse bacterial species can be isolated from the bladder tissue. Histopathological scoring revealed significant edema and alterations of urothelial architecture in RUTI patient biopsies. Lymphocytes, including plasma B-cells, were detected within the mesenchyme, urothelium, and follicular aggregates in the majority of patients, indicating that the local adaptive immune response is active during human RUTI. These data provide conclusive evidence that bacteria invade the human urothelium and suggest that diverse bacterial species and the adaptive immune response play important roles in RUTI in humans. © 2019 Elsevier LtdNational Institutes of Health (NIH; grants R01-AI056404 and R01 GM115188) and the Welch Foundation (grant I-1561).School of Natural Sciences and Mathematic
