Adaptive dynamic networks as models for the immune system and autocatalytic sets

Description: A general class of network models is described that can be used to present complex adaptive systems. These models have two purposes: On a practical level they are closely based on real biological phenomena, and are intended to model detailed aspects of them. On a more general level, however, they provide a framework to address broader questions concerning evolution, pattern recognition, and other properties of living systems. This paper concentrates on the more general level, illustrating the basic concepts with two examples, a model of the immune system and a model for the spontaneous emergence of autocatalytic sets in a chemically reactive polymer soup. 10 refs., 3 figs.

Inter and intra-specific variation in photosynthetic acclimation response to long term exposure of elevated carbon dioxide

Description: The response of intra and interspecific variation in photosynthetic acclimation to growth at elevated atmospheric CO{sub 2} concentration (600{micro}mol mol-l) in six important grassland species was investigated. Plants were grown in a background sward of Lolium perenne and measurements were made after four years of growth at elevated C{sub a}. Elevated CO{sub 2} was maintained using a FACE (Free-Air Carbon Enrichment) system. Significant intra and interspecific variation in acclimation response was demonstrated. The response of adaxial and abaxial stomatal conductance to elevated CO{sub 2} was also investigated. The stomatal conductance of both the adaxial and abaxial leaf surfaces was found to be reduced by elevated C{sub a}. Significant asymmetric responses in stomatal conductance was demonstrated in D. glomerata and T. pratense. Analysis of stomatal indices and densities indicated that the observed reductions in stomatal conductance were probably the result of changes in stomatal aperture.

Genetic manipulation of a cyanobacterium for heavy metal detoxivication

Description: Increasing heavy metal contamination of soil and water has produced a need for economical and effective methods to reduce toxic buildup of these materials. Biological systems use metallothionein proteins to sequester such metals as Cu, Cd, and Zn. Studies are underway to genetically engineer a cyanobacteria strain with increased ability for metallothionein production and increased sequestration capacity. Cyanobacteria require only sunlight and CO{sub 2}. Vector constructs are being developed in a naturally competent, unicellular cyanobacterium Anacystis nidulans R2. Closed copies of a yeast copper metallothionein gene have been inserted into a cyanobacterial shuttle vector as well as a vector designed for genomic integration. Transformation studies have produced recombinant cyanobacteria from both of these systems, and work is currently underway to assess the organism`s ability to withstand increasing Cu, Cd, and Zn concentrations.

Photosynthetic acclimation to elevated carbon dioxide: Basis for variability among plants. Final technical report, September 1, 1988--April 30, 1992

Description: The objective of this research was to investigate the acclimation phenomena involved in plants as they adjust to a CO{sub 2} enriched atmosphere. Plants were grown under various CO{sub 2} concentrations in the controlled chambers of the Duke University Phytotron. Soil nutrients, irradiance, temperature, soil water, and atmospheric relative humidity were controlled. Photosynthesis, leaf structure, leaf biomass of photosynthetic leaves or leaflets and of growth points that are not assimilating CO{sub 2} were measured to determine contributions of carbon source tissues to sink tissues. Export and import rates following movement of plants into atmospheres of higher carbon dioxide concentration were specifically examined.

Living Systems Energy Module

Description: The Living Systems Energy Module, renamed Voyage from the Sun, is a twenty-lesson curriculum designed to introduce students to the major ways in which energy is important in living systems. Voyage from the Sun tells the story of energy, describing its solar origins, how it is incorporated into living terrestrial systems through photosynthesis, how it flows from plants to herbivorous animals, and from herbivores to carnivores. A significant part of the unit is devoted to examining how humans use energy, and how human impact on natural habitats affects ecosystems. As students proceed through the unit, they read chapters of Voyage from the Sun, a comic book that describes the flow of energy in story form (Appendix A). During the course of the unit, an ``Energy Pyramid`` is erected in the classroom. This three-dimensional structure serves as a classroom exhibit, reminding students daily of the importance of energy and of the fragile nature of our living planet. Interactive activities teach students about adaptations that allow plants and animals to acquire, to use and to conserve energy. A complete list of curricular materials and copies of all activity sheets appear in Appendix B.

Photosynthesis, environmental change, and plant adaptation: Research topics in plant molecular ecology. Summary report of a workshop

Description: As we approach the 21st Century, it is becoming increasingly clear that human activities, primarily related to energy extraction and use, will lead to marked environmental changes at the local, regional, and global levels. The realized and the potential photosynthetic performance of plants is determined by a combination of intrinsic genetic information and extrinsic environmental factors, especially climate. It is essential that the effects of environmental changes on the photosynthetic competence of individual species, communities, and ecosystems be accurately assessed. From October 24 to 26, 1993, a group of scientists specializing in various aspects of plant science met to discuss how our predictive capabilities could be improved by developing a more rational, mechanistic approach to relating photosynthetic processes to environmental factors. A consensus emerged that achieving this goal requires multidisciplinary research efforts that combine tools and techniques of genetics, molecular biology, biophysics, biochemistry, and physiology to understand the principles, mechanisms, and limitations of evolutional adaptation and physiological acclimation of photosynthetic processes. Many of these basic tools and techniques, often developed in other fields of science, already are available but have not been applied in a coherent, coordinated fashion to ecological research. The efforts of this research program are related to the broader efforts to develop more realistic prognostic models to forecast climate change that include photosynthetic responses and feedbacks at the regional and ecosystem levels.

Advanced Computational Approaches for Characterizing Stochastic Cellular Responses to Low Dose, Low Dose Rate Exposures

Description: OAK - B135 This project final report summarizes modeling research conducted in the U.S. Department of Energy (DOE), Low Dose Radiation Research Program at the Lovelace Respiratory Research Institute from October 1998 through June 2003. The modeling research described involves critically evaluating the validity of the linear nonthreshold (LNT) risk model as it relates to stochastic effects induced in cells by low doses of ionizing radiation and genotoxic chemicals. The LNT model plays a central role in low-dose risk assessment for humans. With the LNT model, any radiation (or genotoxic chemical) exposure is assumed to increase one¡¯s risk of cancer. Based on the LNT model, others have predicted tens of thousands of cancer deaths related to environmental exposure to radioactive material from nuclear accidents (e.g., Chernobyl) and fallout from nuclear weapons testing. Our research has focused on developing biologically based models that explain the shape of dose-response curves for low-dose radiation and genotoxic chemical-induced stochastic effects in cells. Understanding the shape of the dose-response curve for radiation and genotoxic chemical-induced stochastic effects in cells helps to better understand the shape of the dose-response curve for cancer induction in humans. We have used a modeling approach that facilitated model revisions over time, allowing for timely incorporation of new knowledge gained related to the biological basis for low-dose-induced stochastic effects in cells. Both deleterious (e.g., genomic instability, mutations, and neoplastic transformation) and protective (e.g., DNA repair and apoptosis) effects have been included in our modeling. Our most advanced model, NEOTRANS2, involves differing levels of genomic instability. Persistent genomic instability is presumed to be associated with nonspecific, nonlethal mutations and to increase both the risk for neoplastic transformation and for cancer occurrence. Our research results, based on applications of NEOTRANS2, indicate that nonlinear threshold-type, dose-response relationships for excess stochastic effects (problematic nonlethal mutations, ...

The Hybrid Hero in Early Modern English Literature: A Synthesis of Classical and Contemplative Heroism

Description: In his Book of the Courtier, Castiglione appeals to the Renaissance notion of self-fashioning, the idea that individuals could shape their identity rather than relying solely on the influence of external factors such as birth, social class, or fate. While other early modern authors explore the practice of self-fashioning—Niccolò Machiavelli, for example, surveys numerous princes identifying ways they have molded themselves—Castiglione emphasizes the necessity of modeling one's-self after a variety of sources, "[taking] various qualities now from one man and now from another." In this way, Castiglione advocates for a self-fashioning grounded in a discriminating kind of synthesis, the generation of a new ideal form through the selective combination of various source materials. While Castiglione focuses on the moves necessary for an individual to fashion himself through this act of discriminatory mimesis, his views can explain the ways authors of the period use source material in the process of textual production. As poets and playwrights fashioned their texts, they did so by consciously combining various source materials in order to create not individuals, as Castiglione suggests, but characters to represent new cultural ideals and values. Early moderns viewed the process of textual, as well as cultural production, as a kind of synthesis. Creation through textual fusion is particularly common in early modern accounts of the heroic, in which authors synthesize classical conceptions of the hero, which privilege the completion of martial feats, and Christian notions of the heroic, based on the contemplative nature of Christ. In this dissertation, I demonstrate how Thomas Kyd in The Spanish Tragedy (1585), Edmund Spenser in The Faerie Queene (1590), William Shakespeare in Titus Andronicus (1594), and John Milton in A Mask Presented at Ludlow Castle (1632) syncretized classical and Christian notions of the heroic ideal in order to comment upon and shape political, social, ...

Margaret Dale, Adapting the Stage to the Screen: Aesthetic, Appropriation, and Intimacy in Ballet Programming for Post-War BBC Television

Description: This thesis examines the aesthetic of ballets adapted for BBC Television by producer Margaret Dale, beginning with her entrance to the BBC's training program in 1955 and culminating with her commissioned work Houseparty, which aired in 1964. A historical and organizational framework is discussed regarding the BBC's cultural mission and view of arts programming, as well as general developmental milestones in programming contextualizing Dale's working conditions. Particular focus is placed upon the appropriation of Romantic narrative ballets and their significance in reinforcing an aristocratic and culturally divisive structure in the arts. Textual analyses consider issues of restaging, camera placement, and lighting, as well as television's intimacy and relationship to characterization in ballet narratives.

College Student Adaptability and Greek Membership: A Single Institution Case Study

Description: Since the birth of the United States in 1776, Greek-letter societies have been an integral part of American higher education. Research on the impact of Greek membership varies at best, and often is in conflict from study to study. This study surveyed students affiliated with Greek-letter organizations at the University of North Texas. The research examined the college adaptability of Greek students by gender in five areas: Overall adjustment, academic adjustment, personal-emotional adjustment, social adjustment, and attachment to the institution. The study, conducted in the spring of 2006 at the University of North Texas had 80 respondents. The Student Adaptability to College Questionnaire (SACQ) consisted of 67 items on a 9-point scale. The SACQ is designed to assess how well students adapt to the demands of the college experience. Raw scores and percentile rankings were determined by t-test calculations. Test scores were expressed through t-scores in relation to the standardized sample. Data show no statistical significance in any of the five areas studied: Overall adjustment, academic adjustment, personal-emotional adjustment, social adjustment, or attachment to the institution. Female participants scored higher on all scales than male participants, indicating a slightly higher level of adjustment, though not enough to be significant. Both males and females scored highest in attachment to the institution and social adjustment, while both scored lowest in personal-emotional adjustment.

Environmental stress-mediated changes in transcriptional and translational regulation of protein synthesis in crop plants. Final report

Description: The research described in this final report focused on the influence of stress agents on protein synthesis in crop plants (primarily soybean). Investigations into the `heat shock` (HS) stress mediated changes in transcriptional and translocational regulation of protein synthesis coupled with studies on anaerobic water deficit and other stress mediated alterations in protein synthesis in plants provided the basis of the research. Understanding of the HS gene expression and function(s) of the HSPs may clarify regulatory mechanisms operative in development. Since the reproductive systems of plants if often very temperature sensitive, it may be that the system could be manipulated to provide greater thermotolerance.

Recovery Act: Energy Efficiency of Data Networks through Rate Adaptation (EEDNRA) - Final Technical Report

Description: This Concept Definition Study focused on developing a scientific understanding of methods to reduce energy consumption in data networks using rate adaptation. Rate adaptation is a collection of techniques that reduce energy consumption when traffic is light, and only require full energy when traffic is at full provisioned capacity. Rate adaptation is a very promising technique for saving energy: modern data networks are typically operated at average rates well below capacity, but network equipment has not yet been designed to incorporate rate adaptation. The Study concerns packet-switching equipment, routers and switches; such equipment forms the backbone of the modern Internet. The focus of the study is on algorithms and protocols that can be implemented in software or firmware to exploit hardware power-control mechanisms. Hardware power-control mechanisms are widely used in the computer industry, and are beginning to be available for networking equipment as well. Network equipment has different performance requirements than computer equipment because of the very fast rate of packet arrival; hence novel power-control algorithms are required for networking. This study resulted in five published papers, one internal report, and two patent applications, documented below. The specific technical accomplishments are the following: • A model for the power consumption of switching equipment used in service-provider telecommunication networks as a function of operating state, and measured power-consumption values for typical current equipment. • An algorithm for use in a router that adapts packet processing rate and hence power consumption to traffic load while maintaining performance guarantees on delay and throughput. • An algorithm that performs network-wide traffic routing with the objective of minimizing energy consumption, assuming that routers have less-than-ideal rate adaptivity. • An estimate of the potential energy savings in service-provider networks using feasibly-implementable rate adaptivity. • A buffer-management algorithm that is designed to reduce the size of router ...

The potential effects of concurrent increases in temperature, CO{sub 2} and O{sub 3} on net photosynthesis, as mediated by rubisCO

Description: At the leaf level, under light saturating and light limiting conditions, it is shown that elevated atmospheric CO{sub 2} concentration not only alters the scale of the response of carbon gain to rising temperature, but can alter the direction of response. These points bring into serious question the value of any predictions of plant production which ignore not only the direct effect Of C0{sub 2} on carbon gain, but also the basic interactions of temperature, C0{sub 2} and 0{sub 3}. Whilst many factors may potentially diminish the enhancement of lightsaturated leaf photosynthetic rates with increase in atmospheric CO{sub 2} concentrations, no mechanism has so far been identified which could remove the parallel stimulation of light-limited photosynthesis.
