Qpsk Block-Modulation Codes For Unequal Error Protection, Robert H. Morelos-Zaragoza, Shu Lin

Faculty Publications

Unequal error protection (UEP) codes find applications in broadcast channels, as well as in other digital communication systems, where messages have different degrees of importance. Binary linear UEP (LUEP) codes combined with a Gray mapped QPSK signal set are used to obtain new efficient QPSK block-modulation codes for unequal error protection. Several examples of QPSK modulation codes that have the same minimum squared Euclidean distance as the best QPSK modulation codes, of the same rate and length, are given. In the new constructions of QPSK block-modulation codes, even-length binary LUEP codes are used. Good even-length binary LUEP codes are obtained …

Comments On A Revised Filing System, R. Wilson Freyermuth

Faculty Publications

Professor Edward Adams's article, both in terms of its basic structure and the myriad of options it offers, neatly highlights the basic dilemma facing the Drafting Committee as it addresses the future Article 9 filing system. As he correctly notes, the filing system's shortcomings are largely due to its continued dependence on paper records, despite the increasing sophistication and availability of computerized information technology for both filing and searching. Should the Drafting Committee maintain the basics of the current system (a public, paper-based filing system) and merely attempt to identify and correct the existing shortcomings in that system, with some …

The Regulation Of Carbonic Anhydrase And Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase Activase By Light And Co2 In Chlamydomonas Reinhardtii, Mamta Rawat, James V. Moroney

Faculty Publications

We have investigated the regulation of accumulation of ribulose1,5-bisphosphate carboxylase/oxygenase activase and the periplasmic carbonic anhydrase (CA) in Chlamydomonas reinhardtii. In algae, the periplasmic CA is required for efficient CO2 fixation when the CO2 concentration is low. These two proteins are affected differently by the CO2 level in the environment. The steady-state level of the ribulose-1,5-bisphosphate carboxylase/oxygenase activase transcript was only slightly and transiently affected by a reduction in ambient CO2 concentration, whereas the CA transcript level was strongly induced by air containing ambient (350 parts per million) CO2 (low CO2) conditions. The transcripts for both proteins showed strong oscillations …

Aerobic And Anaerobic Starvation Metabolism In Methanotrophic Bacteria, P. Roslev, G. M. King

Faculty Publications

The capacity for anaerobic metabolism of endogenous and selected exogenous substrates in carbon- and energy-starved methanotrophic bacteria was examined. The methanotrophic isolate strain WP 12 survived extended starvation under anoxic conditions while metabolizing 10-fold less endogenous substrate than did parallel cultures starved under oxic conditions. During aerobic starvation, the cell biomass decreased by 25% and protein and lipids were the preferred endogenous substrates. Aerobic protein degradation (24% of total protein) took place almost exclusively during the initial 24 h of starvation. Metabolized carbon was recovered mainly as CO2 during aerobic starvation. In contrast, cell biomass decreased by only 2.4% during …

Effects Of Inoculation And Wilting On The Preservation And Utilization Of Wheat Forage, C. C. Williams, M. A. Froetschel, L. O. Ely, H. E. Amos

Faculty Publications

Wheat forage was harvested at an early head stage of maturity and ensiled in 12 900-kg experimental silos at three percentages of DM (20.8% for direct-cut forage and 27.9 or 39.3% for wilted forage) either with or without application of a lactic acid bacterial inoculant. The objective was to test the efficacy of the inoculant to alter silage fermentation, preservation, and nutritive value of wheat forage ensiled at different moisture percentages because of wilting. Wilting enhanced DM preservation and decreased fermentation end products. Inoculation made the fermentation more homolactic but did not enhance DM preservation. Silage rations (80% DM as …

Playing "21" With Narcotics Enforcement: A Response To Professor Carrington (Symposium, Regulatory Future Of Contingent Employment), Frank O. Bowman Iii

Faculty Publications

Although I have fundamental disagreements with Professor Carrington even when his argument is reduced to its core, my purpose here is neither to defend every jot and tittle of national drug policy, nor to propose any sweeping personal vision of the place of recreational drugs in America. My ambitions are more modest. I suggest three premises: (1) Intelligent discussion of drug policy requires that we shed the image of law enforcement as warfare. (2) Instead, criminal narcotics prohibitions, penalties, and enforcement methods should be analyzed by the same standards which *939 govern any other type of crime. (3) If antinarcotics …

Anonymous Campaign Literature And The First Amendment, Erika Lietzan

Faculty Publications

Presently, forty-eight states and the District of Columbia have statutes that require the disclosure of some party's identity (for example, an author or a sponsor) on political literature pertaining to elections. The most common explanations given for these statutes are that they deter fraud and libel in the election arena and that they provide valuable information to the voters. Because these statutes regulate core political speech, however, they necessarily implicate the First Amendment to the United States Constitution. Although campaign disclosure laws have been both struck down and sustained by state courts reviewing appealed convictions, the decisions have been disappointingly …

Stability Of Methane Oxidation Capacity To Variations In Methane And Nutrient Concentrations, Sylvia Schnell, Gary M. King

Faculty Publications

Uptake rate constants for atmospheric methane consumption by the 4-6 cm depth interval of a forest soil did not change during 4 months incubation in vitro, even though atmospheric methane concentrations were significantly higher than in situ concentrations. Uptake rate constants were also unaffected by continous incubation at a constant methane concentration of 17 ppm for 2 weeks and 170 ppm for 3 weeks. Uptake rates during incubation with 1000 ppm methane increased 176-fold when assayed with 1000 ppm methane and 5.5-fold when assayed with 1.7 ppm methane. These enhancements were lost after subsequent incubation with atmospheric methane. The ratio …

Mathematical Modeling Of A Nickel-Cadmium Cell: Proton Diffusion In The Nickel Electrode, Pauline De Vidts, Ralph E. White

Faculty Publications

In this paper we present a mathematical model of a sealed nickel-cadmium cell that includes proton diffusion and ohmic drop through the active material in the nickel electrode. The model is used to calculate sensitivity coefficients for various parameters in the model. These calculations show that the discharge voltage of the cell is affected mostly by the kinetics of the nickel reaction. Toward the end of discharge, proton diffusion also becomes important, because the proton diffusion process affects the active material utilization significantly. During charge, the cell voltage is mainly affected by the kinetics of the nickel reaction until the …

Frederic Rzewski And Spontaneous Political Music, Christian T. Asplund

Faculty Publications

I am intrigued by Frederic Rzewski's ability, in his pieces from the 1960s and 70s, to model socio-political phenomena and to teach specific lessons about these phenomena on both intuitive and intellectual levels to both performers and listeners. Performers in particular will literally experience these socio-political phenomena in the course of performing these pieces. Rzewski seems to have achieved Brecht's ideal of a gestic music without dryness or lack of credibility.

Drafting Mediation Privileges: Lessons From The Civil Justice Reform Act, Michael A. Perino

Faculty Publications

Mediation confidentiality provisions or privileges are now prevalent throughout the United States. Forty-one states have enacted some form of mediation privilege. As part of the Administrative Dispute Resolution Act of 1990, Congress enacted legislation to protect confidentiality in mediations involving federal agencies. An additional source for such provisions is the Civil Justice Reform Act of 1990 (CJRA), which required each federal district court to implement a civil justice expense and delay reduction plan (Plan(s)) by the end of 1993. Those Plans seek to implement mechanisms designed to address causes of excessive expense and delay in the federal courts.

Electrowinning Of Non-Noble Metals With Simultaneous Hydrogen Evolution At Flow-Through Porous Electrodes I. Theoretical, Mahmoud M. Saleh, John W. Weidner, Badr G. Ateya

Faculty Publications

A mathematical model is developed to simulate the electrowinning of non-noble metals (e.g., Zn, Cr) within flow-through porous electrodes under the conditions of simultaneous evolution of hydrogen gas bubbles. The results of the model are presented as a function of several dimensionless groups representing kinetics, mass transfer, ohmic resistance, and gas bubbles. These coupled, nonlinear effects are investigated by examining the distributions of the metal reduction and hydrogen evolution currents, coulombic efficiency of the metal electrowinning reaction, and gas void fractions under a series of limiting conditions. The gas bubbles accentuate the nonuniform distribution of the potential and …

Somatic Embryogenesis And Polyamines In Woody Plants, Rakesh Minocha, Subhash C. Minocha, Liisa Kaarina Simola

Faculty Publications

The formation of whole plants from cultured cells is interesting not only because of its applications for mass propagation but also as a prime example of the process of controlled development and differentiation in plants. Cultures capable of producing somatic embryos with high frequency provide ideal experimental systems to study and understand the biochemical basis of hormonal regulation of the developmental process. This knowledge should lead to the planning of media and various treatments that allow us to obtain whole plants from single cells in recalcitrant plant species.

Quechua Texts Of Perception, Janis B. Nuckolls

Faculty Publications

Recent work by anthropologists, folklorists, and semioticians has made significant strides in our understanding of the dynamics and poetics of spoken utterances. Such work has been motivated, generally, by the goal of understanding verbal expression in terms of its own unique structures and expressive modalities. The following paper will contribute to this line of inquiry. It offers an analysis of a form of expression, sound symbolism, that is widely used by people whose languages have not been written down. The main advantage of this analysis is that it rescues sound symbolism from the irrational abyss into which it has often …
