In real materials, nonlinear forces cause the frequencies of vibrating atoms to depend on amplitude. As a consequence, a large-amplitude fluctuation on the scale of the atom spacing can develop a frequency that does not resonate with the normal modes, causing energy to become trapped in an intrinsically localized mode (ILM)--also called 'discrete breather' or 'lattice soliton'. As temperature is increased, entropy is expected to stabilize increased concentrations of these random hotspots. This mechanism, which spontaneously concentrates energy, has been observed in analogous systems on a larger scale, but direct sightings at the atomic scale have proved difficult. Two challenges have hampered progress: (1) the need to separate ILMs from modes associated with crystal imperfections, and (2) complications that arise at high temperatures, including feature broadening and multiphonon processes. Here we solve both of these problems by actively creating ILMs at low temperatures in {alpha}-uranium using high-energy inelastic x-ray and neutron scattering. The ILM creation excitation occurs at energies ten times higher than conventional lattice excitations, cleanly separating it from modes associated with crystal imperfections. The discovery of this excitation not only proves the existence of ILMs in uranium but also opens up a new route for finding ILMs in …

It has been proposed that Congress prohibit the sale or rental to minors of video games that are rated "M" (Mature) or "AO" (Adults Only) by the Entertainment Software Ratings Board. This board is a non-governmental entity established by the Interactive Digital Software Association, and its ratings currently have no legal effect. This report details first amendment principles, violent and sexually explicit video game decisions, and related information.

A letter report issued by the Government Accountability Office with an abstract that begins "The Navy is investing over $3 billion to develop technologies for a new type of aircraft carrier--the Ford class--and it expects to spend almost $11 billion to design and construct the USS Gerald R. Ford (CVN 78)--the lead ship of the class. New technologies are to improve the carrier's performance and reduce crew size. The Navy requested authorization of CVN 78 in its fiscal year 2008 budget. GAO was asked to assess the Navy's ability to meet its goals for developing the new carrier. Specifically, this report assesses (1) the extent to which technology development could affect the capability and construction of CVN 78, (2) the status of efforts to achieve design stability, and (3) the challenges to building CVN 78 within budget. To accomplish this, our work includes analysis of test reports, development schedules, and ship progress reviews; interviews with Navy and other officials; and examinations of cost estimates and our own past work."

This report provides an overview of Secretary of State Rice's transformational diplomacy plan. It examines the calls for reform of America's current diplomatic institutions, and the Administration's response -- transformational diplomacy. The report also presents the concerns many experts have expressed regarding specific elements of this proposal, and a sample of reaction in other countries. The report also discusses various issues that may be considered by Congress.

Email correspondence between multiple recipients discussing Texas Stonewall Democratic Caucus agenda.

In the event of the release of a lethal agent (such as anthrax) inside a building, law enforcement and public health responders take samples to identify and characterize the contamination. Sample locations may be rapidly chosen based on available incident details and professional judgment. To achieve greater confidence of whether or not a room or zone was contaminated, or to certify that detectable contamination is not present after decontamination, we consider a Bayesian model for combining the information gained from both judgment and randomly placed samples. We investigate the sensitivity of the model to the parameter inputs and make recommendations for its practical use.

The City of Brockton, Massachusetts sought to install New England’s largest solar array at a remediated brownfield site on Grove Street. The 425-kilowatt solar photovoltaic array – or “Brightfield” – was installed in an urban park setting along with interpretive displays to maximize the educational opportunities. The “Brightfield” project included 1,395 310-Watt solar panels connected in “strings” that span the otherwise unusable 3.7-acre site. The project demonstrated that it is both technically and economically feasible to install utility scale solar photovoltaics on a capped landfill site. The US Department of Energy conceived the Brightfields program in 2000, and Brockton’s Brightfield is the largest such installation nationwide. Brockton’s project demonstrated that while it was both technically and economically feasible to perform such a project, the implementation was extremely challenging due to the state policy barriers, difficulty obtaining grant funding, and level of sophistication required to perform the financing and secure required state approvals. This demonstration project can be used as a model for other communities that wish to implement “Brownfields to Brightfields” projects; 2) implementing utility scale solar creates economies of scale that can help to decrease costs of photovoltaics; 3) the project is an aesthetic, environmental, educational and economic asset …
