The Black Hole in the Throat - Thermodynamics of Strongly Coupled Cascading Gauge Theories (open access)

The Black Hole in the Throat - Thermodynamics of Strongly Coupled Cascading Gauge Theories

We numerically construct black hole solutions corresponding to the deconfined, chirally symmetric phase of strongly coupled cascading gauge theories at various temperatures. We compute the free energy as a function of the temperature, and we show that it becomes positive below some critical temperature, indicating the possibility of a first order phase transition at which the theory deconfines and restores the chiral symmetry.

The Effect of Magnetic Field on HTS Leads What Happens when thePower Fails at RAL? (open access)

The Effect of Magnetic Field on HTS Leads What Happens when thePower Fails at RAL?

The key to being able to operate the MICE superconducting solenoids on small coolers is the use of high temperature superconducting (HTS) leads between the first stage of the cooler and the magnet, which operates at around 4.2 K. Because MICE magnets are not shielded, all of the MICE magnets have a stray magnetic field in the region where the coolers and the HTS leads are located. The behavior of the HTS leads in a magnetic field depends strongly on the HTS material used for the leads and the temperature of the cooler first stage temperature. The HTS leads can be specified to operate at the maximum current for the magnet. This report shows how the HTS leads can be specified for use the MICE magnets. MICE magnets take from 1.3 hours (the tracker solenoids) to 3.7 hours (the coupling magnet) to charge to the highest projected operating currents. If the power fails, the cooler and the upper ends of the HTS leads warm up. The question is how one can discharge the magnet to protect the HTS leads without quenching the MICE magnets. This report describes a method that one can use to protect the HTS leads in the …

Carrying Out and Developing the Glass Industry Vision and Roadmap

In support of its obligations under the above-mentioned project, the GMIC performed the following tasks: (1) Provided two-way communications liaison services between the U.S. glass industry and the D.O.E. to ensure the needs and concerns of each party are effectively communicated to the other. (2) Updated and modified on a continuing basis and in response to evolving conditions within the glass industry, the goals and priorities outlined in the Glass Industry Vision and the Glass Technology Roadmap. (3) Established relationships with a wide variety of government and non-governmental organizations with interests in further improving the levels of technology, productivity and environmental responsibility of the glass industry. (4) Canvassed the glass industry on an ongoing basis to determine overall and specific sector needs for technological development. (5) Fostered direct contacts between member companies and national laboratories to facilitate the development of individual company technology development. (6) Advised the DOE on the key elements of the solicitation process in support of the Glass Industry Vision and Technology Roadmap. In the course of this contract, the membership of the GMIC has grown to include over 70% of the glass industry. This gives it the ability to communicate persuasively with the vast majority of …

Monte Carlo Simulation of Proton-induced Cosimc Ray Cascades in the Atmosphere (open access)

Monte Carlo Simulation of Proton-induced Cosimc Ray Cascades in the Atmosphere

We have developed a Monte Carlo model of the Earth's atmosphere and implemented it in three different codes (GEANT4, MCNPX, and FLUKA). Primary protons in the energy range of 1 GeV-100 TeV are injected at the top of the atmosphere. The codes follow the tracks of all relevant secondary particles (neutrons, muons, gammas, electrons, and pions) and tally their fluxes at selectable altitudes. Comparisons with cosmic ray data at sea level show good agreement.

Intercellular Genomics of Subsurface Microbial Colonies (open access)

Intercellular Genomics of Subsurface Microbial Colonies

This report summarizes progress in the second year of this project. The objective is to develop methods and software to predict the spatial configuration, properties and temporal evolution of microbial colonies in the subsurface. To accomplish this, we integrate models of intracellular processes, cell-host medium exchange and reaction-transport dynamics on the colony scale. At the conclusion of the project, we aim to have the foundations of a predictive mathematical model and software that captures the three scales of these systems – the intracellular, pore, and colony wide spatial scales. In the second year of the project, we refined our transcriptional regulatory network discovery (TRND) approach that utilizes gene expression data along with phylogenic similarity and gene ontology analyses and applied it successfully to E.coli, human B cells, and Geobacter sulfurreducens. We have developed a new Web interface, GeoGen, which is tailored to the reconstruction of microbial TRNs and solely focuses on Geobacter as one of DOE’s high priority microbes. Our developments are designed such that the frameworks for the TRND and GeoGen can readily be used for other microbes of interest to the DOE. In the context of modeling a single bacterium, we are actively pursuing both steady-state and kinetic …

Atmospheric Radiation Measurement program climate research facility operations quarterly report October 1 - December 31, 2006. (open access)

Atmospheric Radiation Measurement program climate research facility operations quarterly report October 1 - December 31, 2006.

Individual raw data streams from instrumentation at the Atmospheric Radiation Measurement (ARM) Program Climate Research Facility (ACRF) fixed and mobile sites are collected and sent to the Data Management Facility (DMF) at Pacific Northwest National Laboratory (PNNL) for processing in near real time. Raw and processed data are then sent daily to the ACRF Archive, where they are made available to users. For each instrument, we calculate the ratio of the actual number of data records received daily at the Archive to the expected number of data records. The results are tabulated by (1) individual data stream, site, and month for the current year and (2) site and fiscal year dating back to 1998. Table 1 shows the accumulated maximum operation time (planned uptime), the actual hours of operation, and the variance (unplanned downtime) for the period October 1 through December 31, 2006, for the fixed and mobile sites. Although the AMF is currently up and running in Niamey, Niger, Africa, the AMF statistics are reported separately and not included in the aggregate average with the fixed sites. The first quarter comprises a total of 2,208 hours. For all fixed sites, the actual data availability (and therefore actual hours of …

Technical Support and Transfer of Geothrmal Technical Knowledge and Information

The Geo-Heat Center (GHC) staff provided responses to 1442 technical support requests during the contract period (April 1, 2006 to September 30, 2007), which were six quarters under this contract. Our website, consisting of 1900 files, also contributes to our technical assistance activity. Downloaded files were 1,889,323 (3,448 per day) from our website, the total number of users was 1,365,258 (2,491 per day), and the total number of hits were 6,008,500 (10,064 per day). The GHC staff attended 60 workshops, short course and professional meeting and made 29 technical presentations. The staff also prepared and mailed out 2,000 copies of each of five issues of the GHC Quaterly Bulletin which contained 26 articles. We also mailed out approximately 5,000 papers and publications to interested individuals and organizations.

UTag: Long-range Ultra-wideband Passive Radio Frequency Tags (open access)

UTag: Long-range Ultra-wideband Passive Radio Frequency Tags

Long-range, ultra-wideband (UWB), passive radio frequency (RF) tags are key components in Radio Frequency IDentification (RFID) system that will revolutionize inventory control and tracking applications. Unlike conventional, battery-operated (active) RFID tags, LLNL's small UWB tags, called 'UTag', operate at long range (up to 20 meters) in harsh, cluttered environments. Because they are battery-less (that is, passive), they have practically infinite lifetimes without human intervention, and they are lower in cost to manufacture and maintain than active RFID tags. These robust, energy-efficient passive tags are remotely powered by UWB radio signals, which are much more difficult to detect, intercept, and jam than conventional narrowband frequencies. The features of long range, battery-less, and low cost give UTag significant advantage over other existing RFID tags.
