Interoperability And The Need For Intelligent Software, Jens G. Pohl
Interoperability And The Need For Intelligent Software, Jens G. Pohl
Collaborative Agent Design (CAD) Research Center
In my introduction to this year’s conference I will address six questions that I believe come to the core of our conference theme of interoperability. Do we human beings resist change? Is it in fact a human problem and not a technical problem that we are dealing with? Can non-human intelligence exist? Do we even have a need for intelligent software? How did software, particularly intelligent software (i.e., if we accept that there is such a thing) evolve over the past several decades, and what is all this talk about a Semantic Web environment? And, finally, what does the …

Chain Reactions: Archives And The Value Chain In Chemistry's Scientific Communications, Anna K. Gold
Chain Reactions: Archives And The Value Chain In Chemistry's Scientific Communications, Anna K. Gold
Robert E. Kennedy Library
We have heard a great deal about problems of expensive scientific journals; in this last session we are focusing on some solutions to those problems. In order to see our way out of the present cost crisis, we need to broaden our view beyond the value chain associated with scientific journals: journals are part of a much larger value chain of scientific communication. This communication occurs before, during, inside, outside, and after the journal article is published. This suggests that we ought to reframe the question posed in this workshop, and ask ourselves not about the “needs” of chemical and …
Assessment Of Biofuels In California And Potential For Future Utilization, Douglas Williams, James J. Ahern, Keith Ochwat
Assessment Of Biofuels In California And Potential For Future Utilization, Douglas Williams, James J. Ahern, Keith Ochwat
Agribusiness
This study analyzed the potential energy resources contained in the biomass residues from the leading crops and livestock in California. As compared with an earlier similar study by Knutson and Miller (1982), where a total of 24 million tons of biomass was reported having an energy value of 336,000 billion Btu’s, this current study showed a total of over 18 million tons (excluding 7.2 million tons of lumber mill and forest slash residues), which translates to almost 13 million tons of dry matter. The energy value of this biomass is 189,000 billion Btu’s, about 56 % of the 1982 value. …

Evidence That Thyroid Hormone Induces Olfactory Cellular Proliferation In Salmon During A Sensitive Period For Imprinting, Sean C. Lema, Gabrielle A. Nevitt
Evidence That Thyroid Hormone Induces Olfactory Cellular Proliferation In Salmon During A Sensitive Period For Imprinting, Sean C. Lema, Gabrielle A. Nevitt
Biological Sciences
Salmon have long been known to imprint and home to natal stream odors, yet the mechanisms driving olfactory imprinting remain obscure. The timing of imprinting is associated with elevations in plasma thyroid hormone levels, with possible effects on growth and proliferation of the peripheral olfactory system. Here, we begin to test this idea by determining whether experimentally elevated plasma levels of 3,5,3′-triiodothyronine (T3) influence cell proliferation as detected by the 5-bromo-2′-deoxyuridine (BrdU) cell birth-dating technique in the olfactory epithelium of juvenile coho salmon (Oncorhynchus kisutch). We also explore how natural fluctuations in thyroxine (T4) …

Investigation Of Hydrocarbon Phytoremediation Potential Of Lupinus Chamissonis In Laboratory Microcosms, Wendy Martin, Yarrow M. Nelson, Kenneth Hoffman
Investigation Of Hydrocarbon Phytoremediation Potential Of Lupinus Chamissonis In Laboratory Microcosms, Wendy Martin, Yarrow M. Nelson, Kenneth Hoffman
Civil and Environmental Engineering
Controlled laboratory microcosms were used to research the phytoremediation potential of lupines (Lupinus chamissonis) for hydrocarbon-contaminated groundwater at a former oil field near Guadalupe, California. During oil production in the Guadalupe Oil Field, a kerosene-like hydrocarbon mixture was used as a diluent to improve the flow of the heavy crude oil. Leaking tanks and pipes resulted in diluent contamination in the soil and groundwater. Native plant species were planted at a pilot-scale field site to investigate the feasibility of using phytoremediation to remediate the groundwater contamination. In the field, biological and hydrological factors make it difficult to determine the specific …
On The Evolution Of Comparative Advantage In Matching Models, Eric O'N. Fisher, Vikas Kakkar
On The Evolution Of Comparative Advantage In Matching Models, Eric O'N. Fisher, Vikas Kakkar
Economics
This paper examines whether comparative advantage is the long-run outcome of an evolutionary process in the open economy. It formalizes the notion that natural selection eliminates inefficient firms and thus leads to stable and perhaps efficient patterns of world trade. Instead of assuming the existence of a Walrasian auctioneer, we study two simple matching processes that coordinate trade between firms. Our central result is that specialization according to comparative advantage, with the larger country possibly incompletely specialized, is the unique evolutionarily stable state of the world economy.
Complete Genomic Sequence Of Bacteriophage B3, A Mu-Like Phage Of Pseudomonas Aeruginosa, Michael D. Braid, Jennifer L. Silhavy, Christopher L. Kitts, Raul J. Cano, Martha M. Howe
Complete Genomic Sequence Of Bacteriophage B3, A Mu-Like Phage Of Pseudomonas Aeruginosa, Michael D. Braid, Jennifer L. Silhavy, Christopher L. Kitts, Raul J. Cano, Martha M. Howe
Biological Sciences
Bacteriophage B3 is a transposable phage of Pseudomonas aeruginosa. In this report, we present the complete DNA sequence and annotation of the B3 genome. DNA sequence analysis revealed that the B3 genome is 38,439 bp long with a G+C content of 63.3%. The genome contains 59 proposed open reading frames (ORFs) organized into at least three operons. Of these ORFs, the predicted proteins from 41 ORFs (68%) display significant similarity to other phage or bacterial proteins. Many of the predicted B3 proteins are homologous to those encoded by the early genes and head genes of Mu and Mu-like prophages found …
Spatiotemporal Distribution Of Marine Magnetotactic Bacteria In A Seasonally Stratified Coastal Salt Pond, S. L. Simmons, S. M. Sievert, Richard B. Frankel, Dennis A. Bazylinski, K. J. Edwards
Spatiotemporal Distribution Of Marine Magnetotactic Bacteria In A Seasonally Stratified Coastal Salt Pond, S. L. Simmons, S. M. Sievert, Richard B. Frankel, Dennis A. Bazylinski, K. J. Edwards
Physics
The occurrence and distribution of magnetotactic bacteria (MB) were studied as a function of the physical and chemical conditions in meromictic Salt Pond, Falmouth, Mass., throughout summer 2002. Three dominant MB morphotypes were observed to occur within the chemocline. Small microaerophilic magnetite-producing cocci were present at the top of the chemocline, while a greigite-producing packet-forming bacterium occurred at the base of the chemocline. The distributions of these groups displayed sharp changes in abundance over small length scales within the water column as well as strong seasonal fluctuations in population abundance. We identified a novel, greigite-producing rod in the sulfidic hypolimnion …

Proceedings Of The 2004 Onr Decision-Support Workshop Series: Interoperability, Collaborative Agent Design Research Center
Collaborative Agent Design (CAD) Research Center
In August of 1998 the Collaborative Agent Design Research Center (CADRC) of the California Polytechnic State University in San Luis Obispo (Cal Poly), approached Dr. Phillip Abraham of the Office of Naval Research (ONR) with the proposal for an annual workshop focusing on emerging concepts in decision-support systems for military applications. The proposal was considered timely by the ONR Logistics Program Office for at least two reasons. First, rapid advances in information systems technology over the past decade had produced distributed collaborative computer-assistance capabilities with profound potential for providing meaningful support to military decision makers. Indeed, some systems based on …

Identification And Inactivation Of Genetic Loci Involved With Lactobacillus Acidophilus Acid Tolerance, M. Andrea Azcarate-Peril, Eric Altermann, Rebecca L. Hoover- Fitzula, Raul J. Cano, Todd R. Klaenhammer
Biological Sciences
Amino acid decarboxylation-antiporter reactions are one of themost important systems for maintaining intracellular pH betweenphysiological limits under acid stress. We analyzed the Lactobacillusacidophilus NCFM complete genome sequence and selected fouropen reading frames with similarities to genes involved withdecarboxylation reactions involved in acid tolerance in severalmicroorganisms. Putative genes encoding an ornithine decarboxylase,an amino acid permease, a glutamate -aminobutyrate antiporter,and a transcriptional regulator were disrupted by insertionalinactivation. The ability of L. acidophilus to survive low-pHconditions, such as those encountered in the stomach or fermenteddairy foods, was investigated and compared to the abilitiesof early- and late-stationary-phase cells of the mutants bychallenging them with …
