N >= 4 Supergravity Amplitudes from Gauge Theory at Two Loops
We present the full two-loop four-graviton amplitudes in N = 4, 5, 6 supergravity. These results were obtained using the double-copy structure of gravity, which follows from the recently conjectured color-kinematics duality in gauge theory. The two-loop four-gluon scattering amplitudes in N = 0, 1, 2 supersymmetric gauge theory are a second essential ingredient. The gravity amplitudes have the expected infrared behavior: the two-loop divergences are given in terms of the squares of the corresponding one-loop amplitudes. The finite remainders are presented in a compact form. The finite remainder for N = 8 supergravity is also presented, in a form that utilizes a pure function with a very simple symbol.

A 10,000 groove/mm multilayer coated grating for EUV spectroscopy
Ultra-high spectral resolution in the EUV and soft x-ray energy ranges requires the use of very high line density gratings with optimal design resulting in use of a Blazed Multilayer Grating (BMG) structure. Here we demonstrate the production of near-atomically perfect Si blazed substrates with an ultra-high groove density (10,000 l/mm) together with the measured and theoretical performance of an Al/Zr multilayer coating on the grating. A 1st order absolute efficiency of 13percent and 24.6percent was achieved at incidence angles of 11o and 36o respectively. Cross-sectional TEM shows the effect of smoothing caused by the surface mobility of deposited atoms and we correlate this effect with a reduction in peak diffraction efficiency. This work shows the high performance that can be achieved with BMGs based on small-period anisotropic etched Si substrates, but also the constraints imposed by the surface mobility of deposited species.

The 10-20-30 Plan and Persistent Poverty Counties
This report discusses the 10-20-30 plan of reallocating funds in rural development programs toward counties with systemic poverty levels defined as 20% of the population being at or below poverty level for 30 years. This report explains why targeting funds to persistent poverty counties might be of interest, how "persistent poverty" is defined and measured, and how different interpretations of the definition and different data source selections could yield different lists of counties identified as persistently poor. This report does not compare the 10-20-30 plan's advantages and disadvantages against other policy options, nor does it examine the range of programs or policy goals for which the 1020-30 plan might be an appropriate policy tool.

20% Wind by 2030: Overcoming the Challenges in West Virginia
Final Report for '20% Wind by 2030: Overcoming the Challenges in West Virginia'. The objective of this project was to examine the obstacles and constraints to the development of wind energy in West Virginia as well as the obstacles and constraints to the achievement of the national goal of 20% wind by 2030. For the portion contracted with WVU, there were four tasks in this examination of obstacles and constraints. Task 1 involved the establishment of a Wind Resource Council. Task 2 involved conducting limited research activities. These activities involved an ongoing review of wind energy documents including documents regarding the potential for wind farms being located on reclaimed surface mining sites as well as other brownfield sites. The Principal Investigator also examined the results of the Marshall University SODAR assessment of the potential for placing wind farms on reclaimed surface mining sites.

317/319 Phytoremediation site monitoring report - 2009 growing season : final report.
In 1999, Argonne National Laboratory (Argonne) designed and installed a series of engineered plantings consisting of a vegetative cover system and approximately 800 hybrid poplars and willows rooting at various predetermined depths. The plants were installed using various methods including Applied Natural Science's TreeWell{reg_sign} system. The goal of the installation was to protect downgradient surface and groundwater by intercepting the contaminated groundwater with the tree roots, removing moisture from the upgradient soil area, reducing water infiltration, preventing soil erosion, degrading and/or transpiring the residual volatile organic compounds (VOCs), and removing tritium from the subsoil and groundwater. This report presents the results of the monitoring activities conducted by Argonne's Energy Systems (ES) Division in the growing season of 2009. Monitoring of the planted trees began soon after the trees were installed in 1999 and has been conducted every summer since then. As the trees grew and consolidated their growth into the contaminated soil and groundwater, their exposure to the contaminants was progressively shown through tissue sampling. During the 2009 sampling campaign, VOC concentrations found in the French Drain area were in general consistent with or slightly lower than the 2008 results. Additionally, closely repeated, stand wide analyses showed contaminant fluctuations that …

T-1025 IU SciBath-768 detector tests in MI-12
This is a memorandum of understanding between the Fermi National Accelerator Laboratory (Fermilab) and the experimenters of Department of Physics and Center for Exploration of Energy and Matter, Indiana University, who have committed to participate in detector tests to be carried out during the 2012 Fermilab Neutrino program. The memorandum is intended solely for the purpose of recording expectations for budget estimates and work allocations for Fermilab, the funding agencies and the participating institutions. it reflects an arrangement that currently is satisfactory to the parties; however, it is recognized and anticipated that changing circumstances of the evolving research program will necessitate revisions. The parties agree to modify this memorandum to reflect such required adjustments. Actual contractual obligations will be set forth in separate documents. The experimenters propsoe to test their prototype 'SciBat-768' detector in the MI-12 building for 3 months (February-April) in Spring 2012. The major goal of this effort is to measure or limit the flux of beam-induced neutrons in a far-off-axis (> 45{sup o}) location of the Booster Neutrino Beamline (BNB). This flux is of interest for a proposed coherent neutral-current neutrino-argon elastic scattering experiment. A second goal is to collect more test data for the SciBath-768 to …

2010 Census: Key Enumeration Activities Are Moving Forward, but Information Technology Systems Remain a Concern
Testimony issued by the Government Accountability Office with an abstract that begins "In March 2008, GAO designated the 2010 Census a high-risk area in part because of information technology (IT) shortcomings and uncertainty over the ultimate cost of the census, now estimated at around $15 billion. The U.S. Census Bureau (Bureau) has since made improvements to various IT systems and taken other steps to mitigate the risks of a successful census. However, last year, GAO noted that a number of challenges and uncertainties remained, and much work remained to be completed under very tight time frames. As requested, this testimony provides an update on the Bureau's readiness for an effective headcount, covering (1) the status of key IT systems; (2) steps the Bureau has taken to revise its cost estimates; and (3) the extent to which critical enumeration activities, particularly those aimed at hard-to-count populations, are on track. The testimony is based on previously issued and ongoing GAO work."

2010 Census: Operational Changes Made for 2010 Position the U.S. Census Bureau to More Accurately Classify and Identify Group Quarters
Testimony issued by the Government Accountability Office with an abstract that begins "The U.S. Census Bureau (Bureau) is tasked with conducting an accurate count of people living in dwellings known as group quarters as part of the 2010 Census. Group quarters consist of college dormitories, prisons, nursing homes, and other facilities typically owned or managed by an entity providing housing, services, or both for the residents. During the 2000 Census, for a variety of reasons, group quarters were sometimes counted more than once, missed, or included in the wrong location. As requested, this testimony will focus on (1) the extent to which the Bureau has strengthened its procedures for counting group quarters compared to the 2000 Census, and (2) particular challenges and opportunities for an accurate group quarters count in Brooklyn. The testimony is based on previously issued and ongoing GAO work in New York and elsewhere."
