Access to Broadband Networks: The Net Neutrality Debate

Description: This report discusses the current debate over "net neutrality." While there is no single accepted definition of "net neutrality," most agree that any such definition should include the general principles that owners of the networks that compose and provide access to the Internet should not control how consumers lawfully use that network, and they should not be able to discriminate against content provider access to that network.

Afghanistan: U.S. Efforts to Vet Non-U.S. Vendors Need Improvement

Description: A letter report issued by the Government Accountability Office with an abstract that begins "The Departments of Defense (DOD) and State (State) and the United States Agency for International Development (USAID) have collectively obligated billions of dollars for contracts and assistance to support U.S. efforts in Afghanistan. There are concerns that U.S. funds are being diverted to fund insurgent and criminal activity in Afghanistan. In light of these concerns, under the authority of the Comptr… more

Angular and Isospin Asymmetries in the Decays B->K(*)l l-

Description: We use a sample of 384 million B{bar B} decays collected with the BABAR detector at the PEP-II asymmetric e{sup +}e{sup -} storage ring to study the flavor-changing neutral current decays B {yields} K{sup (*)}{ell}{sup +}{ell}{sup -}, where {ell}{sup +}{ell}{sup -} is either e{sup +}e{sup -} or {mu}{sup +}{mu}{sup -}. We present measurements in two dilepton mass bins, one below the J/{psi} resonance and the other above, of the lepton forward-backward asymmetry {Alpha}{sub FB} and the longitudin… more

Annealing to Mitigate Pitting in Electropolished Niobium Coupons and SRF Cavities

Description: Ongoing studies at Fermilab investigate whether dislocations and other factors instigate pitting during cavity electropolishing (EP), despite careful processing controls and the inherent leveling mechanism of EP itself. Here, cold-worked niobium coupons, which exhibited increased tendencies for pitting in our past study, were annealed in a high vacuum furnace and subsequently processed by EP. Laser confocal scanning microscopy and special defect counting algorithms were used to assess the popul… more

Application of an EMCCD Camera for Calibration of Hard X-Ray Telescopes

Description: Recent technological innovations now make it feasible to construct hard x-ray telescopes for space-based astronomical missions. Focusing optics are capable of improving the sensitivity in the energy range above 10 keV by orders of magnitude compared to previously used instruments. The last decade has seen focusing optics developed for balloon experiments and they will soon be implemented in approved space missions such as the Nuclear Spectroscopic Telescope Array (NuSTAR) and ASTRO-H. The full … more

Arizona Border Region: Federal Agencies Could Better Utilize Law Enforcement Resources in Support of Wildland Fire Management Activities

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Wildland fires can result from both natural and human causes. Human-caused wildland fires are of particular concern in Arizona--especially within 100 miles of the U.S.-Mexico border because this is a primary area of entry for illegal border crossers and GAO has previously reported that illegal border crossers have been suspected of igniting wildland fires. Over half of the land in the Arizona border reg… more

ARM Surface Meteorology Systems Instrument Handbook

Description: The ARM Surface Meteorology Systems consist mainly of conventional in situ sensors that obtain a defined “core” set of measurements. The core set of measurements is: Barometric Pressure (kPa), Temperature (°C), Relative Humidity (%), Arithmetic-Averaged Wind Speed (m/s), Vector-Averaged Wind Speed (m/s), and Vector-Averaged Wind Direction (deg).

A Balanced Budget Constitutional Amendment: Background and Congressional Options

Description: One of the most persistent political issues facing Congress in recent decades is whether to require that the budget of the United States be in balance. Although a balanced federal budget has long been held as a political ideal, the accumulation of large deficits in recent years has heightened concern that some action to require a balance between revenues and expenditures may be necessary. This report provides an overview of the issues and options that have been raised during prior consideration… more

Bioinspired Molecular Co-Catalysts Bonded to a Silicon Photocathode for Solar Hydrogen Evolution

Description: The production of fuels from sunlight represents one of the main challenges in the development of a sustainable energy system. Hydrogen is the simplest fuel to produce and although platinum and other noble metals are efficient catalysts for photoelectrochemical hydrogen evolution earth-abundant alternatives are needed for large-scale use. We show that bioinspired molecular clusters based on molybdenum and sulphur evolve hydrogen at rates comparable to that of platinum. The incomplete cubane-lik… more
