Intertemporal Permit Trading for the Control of Greenhouse Gas Emissions
This paper integrates two themes in the intertemporal permit literature through the construction of an intertemporal banking system for a pollutant that creates both stock and flow damages. A permit banking system for the special case of a pollutant that only causes stock damages is also developed

The Oil Security Metrics Model: A Tool for Evaluating the Prospective Oil Security Benefits of DOE's Energy Efficiency and Renewable Energy R&D Programs
Energy technology R&D is a cornerstone of U.S. energy policy. Understanding the potential for energy technology R&D to solve the nation's energy problems is critical to formulating a successful R&D program. In light of this, the U.S. Congress requested the National Research Council (NRC) to undertake both retrospective and prospective assessments of the Department of Energy's (DOE's) Energy Efficiency and Fossil Energy Research programs (NRC, 2001; NRC, 2005). ("The Congress continued to express its interest in R&D benefits assessment by providing funds for the NRC to build on the retrospective methodology to develop a methodology for assessing prospective benefits." NRC, 2005, p. ES-2) In 2004, the NRC Committee on Prospective Benefits of DOE's Energy Efficiency and Fossil Energy R&D Programs published a report recommending a new framework and principles for prospective benefits assessment. The Committee explicitly deferred the issue of estimating security benefits to future work. Recognizing the need for a rigorous framework for assessing the energy security benefits of its R&D programs, the DOE's Office of Energy Efficiency and Renewable Energy (EERE) developed a framework and approach for defining energy security metrics for R&D programs to use in gauging the energy security benefits of their programs (Lee, 2005). This report describes methods for estimating the prospective oil security benefits of EERE's R&D programs that are consistent with the methodologies of the NRC (2005) Committee and that build on Lee's (2005) framework. Its objective is to define and implement a method that makes use of the NRC's typology of prospective benefits and methodological framework, satisfies the NRC's criteria for prospective benefits evaluation, and permits measurement of that portion of the prospective energy security benefits of EERE's R&D portfolio related to oil. While the Oil Security Metrics (OSM) methodology described in this report has been specifically developed to estimate the prospective oil security benefits of DOE's R&D programs, it is also applicable to other strategies and policies aimed at changing U.S. petroleum demand
Integrated Analysis of Market Transformation Scenarios with HyTrans
This report presents alternative visions of the transition of light-duty vehicle transportation in the United States from petroleum to hydrogen power. It is a supporting document to the U.S. Department of Energy's Summary Report, "Analysis of the Transition to a Hydrogen Economy and the Potential Hydrogen Infrastructure Requirements" (U.S. DOE, 2007). Three alternative early transition scenarios were analyzed using a market simulation model called HyTrans. The HyTrans model simultaneously represents the behavior of fuel suppliers, vehicle manufacturers and consumers, explicitly recognizing the importance of fuel availability and the diversity of vehicle choices to consumers, and dependence of fuel supply on the existence of market demand. Competitive market outcomes are simulated by means of non-linear optimization of social surplus through the year 2050. The three scenarios specify different rates and geographical distributions of market penetration for hydrogen fuel cell vehicles from 2012 through 2025. Scenario 1 leads to 2 million vehicles on U.S. roads by 2025, while Scenarios 2 and 3 result in 5 million and 10 million FCVs in use by 2025, respectively. The HyTrans model "costs out" the transition scenarios and alternative policies for achieving them. It then tests whether the scenarios, together with the achievement of the DOE's technology goals for fuel cell vehicles and hydrogen infrastructure technologies could lead to a sustainable transition to hydrogen powered transportation. Given the achievement of DOE's ambitious technology goals, all three scenarios appear to lead to a sustainable transition to hydrogen. In the absence of early transition deployment effort, no transition is likely to begin before 2045. The cumulative costs of the transition scenarios to the government range from 45 billion, depending on the scenario, the policies adopted and the degree of cost-sharing with industry. In the absence of carbon constraining policies, the transition to hydrogen achieves about the same reduction in CO2 emissions as a transition to advanced gasoline-electric hybrid vehicles. With significant carbon policy, drastic reductions in well-to-wheel CO2 emissions are possible. Energy transition modeling is a newly evolving field and much remains to be done to improve the utility of models like HyTrans

Mast Cell-Derived Histamine Mediates Cystitis Pain
Background: Mast cells trigger inflammation that is associated with local pain, but the mechanisms mediating pain are unclear. Interstitial cystitis (IC) is a bladder disease that causes debilitating pelvic pain of unknown origin and without consistent inflammation, but IC symptoms correlate with elevated bladder lamina propria mast cell counts. We hypothesized that mast cells mediate pelvic pain directly and examined pain behavior using a murine model that recapitulates key aspects of IC. Methods and Findings: Infection of mice with pseudorabies virus (PRV) induces a neurogenic cystitis associated with lamina propria mast cell accumulation dependent upon tumor necrosis factor alpha (TNF), TNF-mediated bladder barrier dysfunction, and pelvic pain behavior, but the molecular basis for pelvic pain is unknown. In this study, both PRV-induced pelvic pain and bladder pathophysiology were abrogated in mast cell-deficient mice but were restored by reconstitution with wild type bone marrow. Pelvic pain developed normally in TNF- and TNF receptor-deficient mice, while bladder pathophysiology was abrogated. Conversely, genetic or pharmacologic disruption of histamine receptor H1R or H2R attenuated pelvic pain without altering pathophysiology. Conclusions: These data demonstrate that mast cells promote cystitis pain and bladder pathophysiology through the separable actions of histamine and TNF, respectively. Therefore, pain is independent of pathology and inflammation, an
