Social Security Numbers: Use is Widespread and Protection Could Be Improved

Description: Testimony issued by the Government Accountability Office with an abstract that begins "Since its creation, the Social Security number (SSN) has evolved beyond its intended purpose to become the identifier of choice for public and private sector entities, and it is now used for myriad non-Social Security purposes. This is significant because a person's SSN, along with name and date of birth, are the key pieces of personal information used to perpetrate identity theft. Consequently, the potential… more

Medicare Part D: CMS's Process and Policy for Enrolling New Dual-Eligible Beneficiaries

Description: Testimony issued by the Government Accountability Office with an abstract that begins "Under the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA), dual-eligible beneficiaries--individuals with both Medicare and Medicaid coverage--have their drug costs covered under Medicare Part D rather than under state Medicaid programs. The MMA requires the Centers for Medicare & Medicaid Services (CMS) to enroll these beneficiaries in a Medicare prescription drug plan (PDP) if th… more

Compensatory Paracrine Mechanisms That Define The Urothelial Response to Injury in Partial Bladder Outlet Obstruction

Description: Diseases and conditions affecting the lower urinary tract are a leading cause of dysfunctional sexual health, incontinence, infection, and kidney failure. The growth, differentiation, and repair of the bladder's epithelial lining are regulated, in part, by fibroblast growth factor (FGF)-7 and -10 via a paracrine cascade originating in the mesenchyme (lamina propria) and targeting the receptor for FGF-7 and -10 within the transitional epithelium (urothelium). The FGF-7 gene is located at the… more

Toward a Deeper Understanding of Plutonium

Description: Plutonium is a very complex element lying near the middle of the actinide series. On the lower atomic number side of Pu is the element neptunium; its 5f electrons are highly delocalized or itinerant, participating in metallic-like bonding. The electrons in americium, the element to the right of Pu, are localized and do not participant significantly in the bonding. Plutonium is located directly on this rather abrupt transition. In the low-temperature {alpha} phase ground state, the five 5f elect… more

Unified Model of Dynamic Forced Barrier Crossing in Single Molecules

Description: Thermally activated barrier crossing in the presence of an increasing load can reveal kinetic rate constants and energy barrier parameters when repeated over a range of loading rates. Here we derive a model of the mean escape force for all relevant loading rates--the complete force spectrum. Two well-known approximations emerge as limiting cases; one of which confirms predictions that single-barrier spectra should converge to a phenomenological description in the slow loading limit.

Temporal Development of Ion Beam Mean Charge State in PulsedVacuum Arc Ion Sources

Description: Vacuum arc ion sources, commonly also known as "Mevva" ionsources, are used to generate intense pulsed metal ion beams. It is knownthat the mean charge state of the ion beam lies between 1 and 4,depending on cathode material, arc current, arc pulse duration, presenceor absence of magnetic field at the cathode, as well background gaspressure. A characteristic of the vacuum arc ion beam is a significantdecrease in ion charge state throughout the pulse. This decrease can beobserved up to a few mil… more

High Gradient Induction Accelerator

Description: A new type of compact induction accelerator is under development at the Lawrence Livermore National Laboratory that promises to increase the average accelerating gradient by at least an order of magnitude over that of existing induction machines. The machine is based on the use of high gradient vacuum insulators, advanced dielectric materials and switches and is stimulated by the desire for compact flash x-ray radiography sources. Research describing an extreme variant of this technology aimed … more

A Novel Approach to Mineral Carbonation: Enhancing Carbonation While Avoiding Mineral Pretreatment Process Cost

Description: Known fossil fuel reserves, especially coal, can support global energy demands for centuries to come, if the environmental problems associated with CO{sub 2} emissions can be overcome. Unlike other CO{sub 2} sequestration candidate technologies that propose long-term storage, mineral sequestration provides permanent disposal by forming geologically stable mineral carbonates. Carbonation of the widely occurring mineral olivine (e.g., forsterite, Mg{sub 2}SiO{sub 4}) is a large-scale sequestratio… more

A "Snowflake" Divertor and its Properties

Description: Handling the power and particle exhaust in fusion reactors based on tokamaks is a challenging problem [1,2]. To bring the energy flux to the divertor plates to an acceptable level (< 10 MW/m2), it is desirable to significantly increase poloidal flux expansion in the divertor area. Some recent ideas include that of a so-called X divertor [3] and a 'snowflake' divertor [4]. We use an acronym SF to designate the latter. In this paper we concentrate on the SF divertor. The general idea behind th… more

Absolute Measurement of Electron Cloud Density

Description: Beam interaction with background gas and walls produces ubiquitous clouds of stray electrons that frequently limit the performance of particle accelerator and storage rings. Counterintuitively we obtained the electron cloud accumulation by measuring the expelled ions that are originated from the beam-background gas interaction, rather than by measuring electrons that reach the walls. The kinetic ion energy measured with a retarding field analyzer (RFA) maps the depressed beam space-charge poten… more

Foreign Science and Engineering Presence in U.S. Institutions and the Labor Force

Description: This report discusses the increased presence of foreign students in graduate science and engineering programs and in the scientific workforce that has been and continues to be of concern to some in the scientific community. Enrollment of U.S. citizens in graduate science and engineering programs has not kept pace with that of foreign students in those programs. Many in the scientific community maintain that in order to compete with countries that are rapidly expanding their scientific and techn… more
