Captain John R. Hughes, Lone Star Ranger is the first full and complete modern biography of a man who served as a Texas Ranger from 1887 until early 1915. He came to the attention of the Rangers after doggedly trailing horse thieves for nearly a year and recovering his stolen stock. After helping Ranger Ira Aten track down another fugitive from justice, Hughes then joined Company D of the Texas Rangers on Aten’s recommendation, intending to stay for only a few months; he remained in the service for nearly thirty years. When Sgt. Charles Fusselman was killed by bandits, Hughes took his place. When Captain Frank Jones was killed by bandits in 1893, Hughes was named captain of Company D. As captain, Hughes and his men searched the border and identified every bandit involved in the killing of Jones. They all received justice. Toward the end of his career Hughes became a senior captain based in Austin, and in 1915, having served as a captain and ranger longer than any other man, he retired from the force. His later years were happy ones, with traveling and visiting friends and relatives. He became a Texas icon and national celebrity, receiving more …

A letter report issued by the Government Accountability Office with an abstract that begins "Carbon offsets are reductions in greenhouse gas emissions in one place to compensate for emissions elsewhere. Examples of offset projects include planting trees, developing renewable energy sources, or capturing emissions from landfills. Recent congressional proposals would have limited emissions from utilities, industries, or other "regulated entities," and allowed these entities to buy offsets. Research suggests that offsets can significantly lower the cost of a program to limit emissions because buying offsets may cost regulated entities less than making the reductions themselves. Some existing international and U.S. regional programs allow offsets to be used for compliance with emissions limits. A number of voluntary offset programs also exist, where buyers do not face legal requirements but may buy offsets for other reasons. Prior GAO work found that it can be difficult to ensure offset quality--that offsets achieve intended reductions. One quality criterion is that reductions must be "additional" to what would have occurred without the offset program. This report provides information on (1) key challenges in assessing the quality of different types of offsets and (2) options for addressing key challenges associated with offset quality if the U.S. …

Correspondence issued by the Government Accountability Office with an abstract that begins "Al Qaeda, the Taliban, and other extremists have used safe havens along Pakistan's Western Frontier (border) region to attack Pakistani, Afghan, U.S., and coalition troops; plan and train for attacks against U.S. interests and the U.S. homeland; destabilize Pakistan, a nuclear-armed U.S. ally; and spread radical Islamic ideologies that threaten U.S. interests. A key U.S. national security objective is to disrupt, dismantle, and defeat al Qaeda and its violent extremist affiliates in Pakistan and to deny them a safe haven. Since 2002, the United States has provided over $18 billion in assistance and reimbursement to Pakistan including (1) reimbursements to the Pakistani government for costs incurred in direct support of U.S. counterterrorism operations; (2) security assistance such as grants to Pakistan for the acquisition of military equipment; and (3) development, economic, and humanitarian assistance. Since 2006, this assistance has included $1.5 billion to improve the counterterrorism and counterinsurgency capabilities of Pakistani security forces operating along the country's border with Afghanistan, including $400 million for the Pakistan Counterinsurgency Fund (PCF) and $700 million for the Pakistan Counterinsurgency Capabilities Fund (PCCF). The President has requested an additional $1.2 billion for …

Testimony issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) reports that the nearly 2,000-mile U.S. border with Mexico is vulnerable to cross-border illegal activity. The Office of Border Patrol (Border Patrol), within DHS's U.S. Customs and Border Protection (CBP), is responsible for securing the border between U.S. ports of entry and has divided responsibility for southwest border miles among nine Border Patrol sectors. CBP reported spending about $3 billion on Border Patrol's southwest border efforts in fiscal year 2010, apprehending over 445,000 illegal entries. This testimony provides preliminary observations on (1) the extent to which DHS reported progress in achieving operational control--Border Patrol was able to detect, respond, and interdict cross-border illegal activity--of the southwest border; (2) the extent to which operational control reflects Border Patrol's ability to respond to illegal activity at the border or after entry into the United States; and (3) how DHS reports the transition to new border security measures will change oversight and resource requirements for securing the southwest border. This testimony is based on GAO's ongoing work for the House Committee on Homeland Security. GAO analyzed DHS border security documents and data supporting border security …

Testimony issued by the Government Accountability Office with an abstract that begins "Many federal programs and initiatives involve shared responsibilities--and benefits--for the federal, state, local and tribal governments, and the private sector. Federal statutes and rules often require nonfederal parties to expend their resources in support of certain national goals. The Unfunded Mandates Reform Act of 1995 (UMRA) was enacted to address some of the concerns about federal statutes and regulations that require nonfederal parties to expend resources to achieve these goals without being provided funding to cover the costs. UMRA generates information about how these potential federal mandates could affect other levels of government and the private sector as Congress and agency decision makers consider proposed legislation and regulations. Congress has asked GAO to evaluate the effectiveness of UMRA procedures and requirements several times since it was enacted. Based on that body of work, this testimony focuses on Title II of UMRA regarding federal mandates in rules and (1) describes the exceptions and exclusions in the act when identifying a federal mandate and (2) summarizes GAO findings on UMRA's implementation over the years and views of knowledgeable parties on potential improvements. GAO is not making recommendations in this testimony."

Replacement of methane with carbon dioxide in hydrate has been proposed as a strategy for geologic sequestration of carbon dioxide (CO{sub 2}) and/or production of methane (CH{sub 4}) from natural hydrate deposits. This replacement strategy requires a better understanding of the thermodynamic characteristics of binary mixtures of CH{sub 4} and CO{sub 2} hydrate (CH{sub 4}-CO{sub 2} mixed hydrates), as well as thermophysical property changes during gas exchange. This study explores the thermal dissociation behavior and dissociation enthalpies of CH{sub 4}-CO{sub 2} mixed hydrates. We prepared CH{sub 4}-CO{sub 2} mixed hydrate samples from two different, well-defined gas mixtures. During thermal dissociation of a CH{sub 4}-CO{sub 2} mixed hydrate sample, gas samples from the head space were periodically collected and analyzed using gas chromatography. The changes in CH{sub 4}-CO{sub 2} compositions in both the vapor phase and hydrate phase during dissociation were estimated based on the gas chromatography measurements. It was found that the CO{sub 2} concentration in the vapor phase became richer during dissociation because the initial hydrate composition contained relatively more CO{sub 2} than the vapor phase. The composition change in the vapor phase during hydrate dissociation affected the dissociation pressure and temperature; the richer CO{sub 2} in the vapor …

As a result of soaring energy demand from a staggering pace of economic expansion and the related growth of energy-intensive industry, China overtook the United States to become the world's largest contributor to CO{sub 2} emissions in 2007. At the same time, China has taken serious actions to reduce its energy and carbon intensity by setting both a short-term energy intensity reduction goal for 2006 to 2010 as well as a long-term carbon intensity reduction goal for 2020. This study presents a China Energy Outlook through 2050 that assesses the role of energy efficiency policies in transitioning China to a lower emission trajectory and meeting its intensity reduction goals. Over the past few years, LBNL has established and significantly enhanced its China End-Use Energy Model which is based on the diffusion of end-use technologies and other physical drivers of energy demand. This model presents an important new approach for helping understand China's complex and dynamic drivers of energy consumption and implications of energy efficiency policies through scenario analysis. A baseline ('Continued Improvement Scenario') and an alternative energy efficiency scenario ('Accelerated Improvement Scenario') have been developed to assess the impact of actions already taken by the Chinese government as well as …

The Aerial Measurement System (AMS) Helicopter Emergency Response Acquisition System provides a thorough and economical means to identify and characterize the contaminants for large area radiological surveys. The helicopter system can provide a 100-percent survey of an area that qualifies as a scoping survey under the Multi-Agency Radiation Survey and Site Investigation Manual (MARSSIM) methodology. If the sensitivity is adequate when compared to the clean up values, it may also be used for the characterization survey. The data from the helicopter survey can be displayed and manipulated to provide invaluable data during remediation activities.

This research will focus on characterizing the phase behavior of polyelectrolyte-surfactant microemulsions (PSM) that were recently discovered in our lab and indentifing possible uses of their long-range ordered nanostructures towards bioseparation, oil-recovery and drug delivery systems. In addition, we are proposing strategies for synthesizing solid and long-range ordered materials with unit cells on the nanometer scale using polymerization and/or cross-linking to solidify the soft template.

The valence fluctuation compounds are rare earth intermetallics where hybridization of the nearly-localized 4f electrons with the conduction electrons leads to incorporation of the 4f's into the itinerant states. This hybridization slows down the conduction electrons and hence gives them a heavy effective mass, justifying application of the term 'heavy Fermion' (HF) to these materials. During the project period, we grew large single crystals of several such compounds and measured their properties using both standard thermodynamic probes and state-of-the-art inelastic neutron scattering. We obtained three main results. For the intermediate valence compounds CePd{sub 3} and YbAl{sub 3}, we showed that the scattering of neutrons by the fluctuations of the 4f magnetic moment does not have the momentum dependence expected for the itinerant heavy mass state; rather, the scattering is more typical of a localized spin fluctuation. We believe that incoherent scattering localizes the excitation. For the heavy Fermion compound Ce(Ni{sub 0.935}Pd{sub 0.065}){sub 2}Ge{sub 2}, which sits at a T = 0 critical point for transformation into an antiferromagnetic (AF) phase, we showed that the scattering from the AF fluctuations does not exhibit any of the divergences that are expected at a phase transition. We speculate that alloy disorder profoundly suppresses …

CT scanners are deployed world-wide to detect explosives in checked and carry-on baggage. Though very similar to single- and dual-energy multi-slice CT scanners used today in medical imaging, some recently developed explosives detection scanners employ multiple sources and detector arrays to eliminate mechanical rotation of a gantry, photon counting detectors for spectral imaging, and limited number of views to reduce cost. For each bag scanned, the resulting reconstructed images are first processed by automated threat recognition algorithms to screen for explosives and other threats. Human operators review the images only when these automated algorithms report the presence of possible threats. The US Department of Homeland Security (DHS) has requirements for future scanners that include dealing with a larger number of threats, higher probability of detection, lower false alarm rates and lower operating costs. One tactic that DHS is pursuing to achieve these requirements is to augment the capabilities of the established security vendors with third-party algorithm developers. A third-party in this context refers to academics and companies other than the established vendors. DHS is particularly interested in exploring the model that has been used very successfully by the medical imaging industry, in which university researchers develop algorithms that are eventually …

The US Department of Homeland Security (DHS) has requirements for future explosive detection scanners that include dealing with a larger number of threats, higher probability of detection, lower false alarm rates and lower operating costs. One tactic that DHS is pursuing to achieve these requirements is to augment the capabilities of the established security vendors with third-party algorithm developers. The purposes of this presentation are to review DHS's objectives for involving third parties in the development of advanced algorithms and then to discuss how these objectives are achieved using workshops and grand challenges. Terrorists are still trying and they are getting more sophisticated. There is a need to increase the number of smart people working on homeland security. Augmenting capabilities and capacities of system vendors with third-parties is one tactic. Third parties can be accessed via workshops and grand challenges. Successes have been achieved to date. There are issues that need to be resolved to further increase third party involvement.

The magnetotelluric method employs co-located surface measurements of electric and magnetic fields to infer the local electrical structure of the earth. The frequency-dependent 'apparent resistivity' curves can be inaccurate at long periods if input data are contaminated - even when robust remote reference techniques are employed. Data despiking prior to processing can result in significantly more reliable estimates of long period apparent resistivities. This paper outlines a two-step method of automatic identification and replacement for spike-like contamination of magnetotelluric data; based on the simultaneity of natural electric and magnetic field variations at distant sites. This simultaneity is exploited both to identify windows in time when the array data are compromised, and to generate synthetic data that replace observed transient noise spikes. In the first step, windows in data time series containing spikes are identified via intersite comparison of channel 'activity' - such as the variance of differenced data within each window. In the second step, plausible data for replacement of flagged windows is calculated by Wiener filtering coincident data in clean channels. The Wiener filters - which express the time-domain relationship between various array channels - are computed using an uncontaminated segment of array training data. Examples are shown where …

A new numerical method is described for the fully iterated, conjugate solution of two discrete submodels, involving (a) a transport network model for heat, moisture, and airflows in a high-permeability, air-filled cavity; and (b) a variably saturated fractured porous medium. The transport network submodel is an integrated-parameter, computational fluid dynamics solver, describing the thermal-hydrologic transport processes in the flow channel system of the cavity with laminar or turbulent flow and convective heat and mass transport, using MULTIFLUX. The porous medium submodel, using TOUGH2, is a solver for the heat and mass transport in the fractured rock mass. The new model solution extends the application fields of TOUGH2 by integrating it with turbulent flow and transport in a discrete flow network system. We present demonstrational results for a nuclear waste repository application at Yucca Mountain with the most realistic model assumptions and input parameters including the geometrical layout of the nuclear spent fuel and waste with variable heat load for the individual containers. The MULTIFLUX and TOUGH2 model elements are fully iterated, applying a programmed reprocessing of the Numerical Transport Code Functionalization model-element in an automated Outside Balance Iteration loop. The natural, convective airflow field and the heat and mass transport …
