Alien Registration: Usefulness of a Nonimmigrant Alien Annual Address Reporting Requirement Is Questionable
A letter report issued by the Government Accountability Office with an abstract that begins "Since 1940, Congress has provided a statutory framework that requires aliens entering or residing in the United States to provide address information. By 1981, aliens who remain in the United States for 30 days or more were required to initially register and report their address information and then to report their change of address only if they move. In the months immediately following the terrorist attacks on September 11, 2001, federal investigators' efforts to locate and interview nearly one-half of the 4,112 nonimmigrant aliens they attempted to contact were impeded by lack of current address information. Nonimmigrant aliens are defined as those who seek temporary entry into the United States for a specific purpose, including those aliens who are in the country as students, international representatives, or temporary workers, or for business or pleasure. Because of growing concern over the government's need to locate aliens, the Enhanced Border Security and Visa Entry Reform Act of 2002 directed GAO to study the feasibility and the utility of a requirement that each nonimmigrant alien in the United States self-report a current address on a yearly basis."

Analysis of Devonian Black Shales in Kentucky for Potential Carbon Dioxide Sequestration and Enhanced Natural Gas Production Quarterly Report: October-December 2004
Devonian gas shales underlie approximately two-thirds of Kentucky. In the shale, natural gas is adsorbed on clay and kerogen surfaces. This is analogous to methane storage in coal beds, where CO{sub 2} is preferentially adsorbed, displacing methane. Black shales may similarly desorb methane in the presence of CO{sub 2}. Drill cuttings from the Kentucky Geological Survey Well Sample and Core Library were sampled to determine CO{sub 2} and CH{sub 4} adsorption isotherms. Sidewall core samples were acquired to investigate CO{sub 2} displacement of methane. An elemental capture spectroscopy log was acquired to investigate possible correlations between adsorption capacity and mineralogy. Average random vitrinite reflectance data range from 0.78 to 1.59 (upper oil to wet gas and condensate hydrocarbon maturity range). Total organic content determined from acid-washed samples ranges from 0.69 to 14 percent. CO{sub 2} adsorption capacities at 400 psi range from a low of 14 scf/ton in less organic-rich zones to more than 136 scf/ton. There is a direct correlation between measured total organic carbon content and the adsorptive capacity of the shale; CO{sub 2} adsorption capacity increases with increasing organic carbon content. Initial estimates based on these data indicate a sequestration capacity of 5.3 billion tons of CO{sub …

Applications of Morphochronology to the Active Tectonics of Tibet
The Himalayas and the Tibetan Plateau were formed as a result of the collision of India and Asia, and provide an excellent opportunity to study the mechanical response of the continental lithosphere to tectonic stress. Geophysicists are divided in their views on the nature of this response advocating either (1) homogeneously distributed deformation with the lithosphere deforming as a fluid continuum or (2) deformation is highly localized with the lithosphere that deforms as a system of blocks. The resolution of this issue has broad implications for understanding the tectonic response of continental lithosphere in general. Homogeneous deformation is supported by relatively low decadal, geodetic slip-rate estimates for the Altyn Tagh and Karakorum Faults. Localized deformation is supported by high millennial, geomorphic slip-rates constrained by both cosmogenic and radiocarbon dating on these faults. Based upon the agreement of rates determined by radiocarbon and cosmogenic dating, the overall linearity of offset versus age correlations, and on the plateau-wide correlation of landscape evolution and climate history, the disparity between geomorphic and geodetic slip-rate determinations is unlikely to be due to the effects of surface erosion on the cosmogenic age determinations. Similarly, based upon the consistency of slip-rates over various observation intervals, secular variations …

ATOMIC BEAM POLARIZATION MEASUREMENT OF THE RHIC POLARIZED H-JET TARGET.
The RHIC polarized H-Jet measures the polarization of the RHIC proton beam via elastic scattering off a nuclear polarized atomic hydrogen beam. The atomic beam is produced by a dissociator, a beam forming system and sextupole magnets. Nuclear polarization is achieved by exchanging occupation numbers of hyperfine states using high frequency transitions. The polarization was measured using a modified form of a Breit-Rabi polarimeter including focusing magnets and another set of high frequency transitions. The sampling of a large part of the beam and low noise electronics made it possible to measure the polarization to a high degree of accuracy in a very short time period (1 min). Using this system, we measured no depolarization of the atomic beam due to the RF fields of the bunched proton beam. Time-of-Flight measurements were done using a fast chopper and a QMA at the position of the RHIC interaction point to determine the areal density of the atomic beam seen by the RHIC beam.

ATOMIC BEAM STUDIES IN THE RHIC H-JET POLARIMETER.
The results of atomic beam production studies are presented. Improved cooling of the atoms before jet formation in the dissociator cold nozzle apparently reduces the atomic beam velocity spread and improves beam focusing conditions. A carefully designed sextupole separating (and focusing) magnet system takes advantage of the high brightness source. As a result a record beam intensity of a 12.4 {center_dot} 10{sup 16} atoms/s was obtained within 10 mm acceptance at the collision point. The results of the polarization dilution factor measurements (by the hydrogen molecules at the collision point) are also presented.

Black Holes, q-Deformed 2d Yang-Mills, and Non-perturbative Topological Strings
We count the number of bound states of BPS black holes on local Calabi-Yau three-folds involving a Riemann surface of genus g. We show that the corresponding gauge theory on the brane reduces to a q-deformed Yang-Mills theory on the Riemann surface. Following the recent connection between the black hole entropy and the topological string partition function, we find that for a large black hole charge N, up to corrections of O(e^-N), Z_BH is given as a sum of a square of chiral blocks, each of which corresponds to a specific D-brane amplitude. The leading chiral block, the vacuum block, corresponds to the closed topological string amplitudes. The sub-leading chiral blocks involve topological string amplitudes with D-brane insertions at 2g-2 points on the Riemann surface analogous to the Omega points in the large N 2d Yang-Mills theory. The finite N amplitude provides a non-perturbative definition of topological strings in these backgrounds. This also leads to a novel non-perturbative formulation of c=1 non-critical string at the self-dual radius.

Chemical And Biological Defense: Army and Marine Corps Need to Establish Minimum Training Tasks and Improve Reporting for Combat Training Centers
A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Defense (DOD) believes that it is increasingly likely that an adversary will use nuclear, biological, or chemical (NBC) weapons against U.S. forces. Consequently, DOD doctrine calls for U.S. forces to be sufficiently trained to continue their missions in an NBC-contaminated environment. Given longstanding concerns about the preparedness of DOD's servicemembers in this critical area, GAO has undertaken a body of work covering NBC protective equipment and training. For this review, GAO was asked to determine the following: (1) To what extent do Army and Marine Corps units and personnel attending combat training centers participate in NBC training, and to what extent do these units and personnel perform NBC tasks at the centers to service standards? (2) Do the Army and the Marine Corps report NBC training at the centers in a standardized format that allows the services to identify lessons learned and to do cross-unit and cross-center comparisons?"

COST-EFFECTIVE METHOD FOR PRODUCING SELF SUPPORTED PALLADIUM ALLOY MEMBRANES FOR USE IN EFFICIENT PRODUCTION OF COAL DERIVED HYDROGEN
Over the last quarter, we developed procedures for producing free-standing, defect free films using rigid silicon and glass substrates over areas up to 12 square inches. Since formation of contiguous Pd-Cu films in the 2-3 {micro}m-thick range is ultimately governed by the size of the particle contamination on the supporting substrate surface, we have adopted techniques utilized by the semiconductor industry to reduce and eventually eliminate particle contamination. We have found these techniques to be much more effective on rigid substrates and have made a down select decision on removal methods (a key milestone) based on these results and the performance of membranes fabricated by this technique. The path to fabricating even larger membranes is straightforward and will be demonstrated in the coming months. Hydrogen permeation tests were also conducted this quarter on as-deposited, Pd-Cu membranes, between 6-14 {micro}m-thick. In the case of a 6 {micro}m-thick film, the pure hydrogen flux at 20 psig and {approx}260 C was 36 cm{sup 3}(STP)/cm{sup 2} min. This flux corresponds to a pure hydrogen permeability of 7.4 {center_dot} 10{sup -5} cm{sup 3} cm cm{sup -2} s{sup -1} cm Hg{sup -1/2} at 250 C. This value is within 20% of the pure hydrogen permeability at …

Democracy in Russia: Trends and Implications for U.S. Interests
U.S. attention has focused on Russia's fitful democratization since Russia emerged in 1991 from the collapse of the Soviet Union. Many observers have argued that a democratic Russia with free markets would be a cooperative bilateral and multilateral partner rather than an insular and hostile national security threat. President Putin's 2004 proposal to restructure the government has been supported by international observers. The U.S. Administration and Congress have welcomed some cooperation with Russia on vital U.S. national security concerns, including the non-proliferation of weapons of mass destruction, among other issues.

DOWNHOLE VIBRATION MONITORING & CONTROL SYSTEM
The objective of this program is to develop a system to both monitor the vibration of a bottomhole assembly, and to adjust the properties of an active damper in response to these measured vibrations. Phase I of this program, which entailed modeling and design of the necessary subsystems and design, manufacture and test of a full laboratory prototype, was completed on May 31, 2004. The principal objectives of Phase II are: more extensive laboratory testing, including the evaluation of different feedback algorithms for control of the damper; design and manufacture of a field prototype system; and, testing of the field prototype in drilling laboratories and test wells. The redesign and upgrade of the laboratory prototype was completed on schedule and it was assembled during the last period. Testing was begin during the first week of October. Initial results indicated that the dynamic range of the damping was less than predicted and that the maximum damping was also less than required. A number of possible explanations for these results were posited, and test equipment was acquired to evaluate the various hypotheses. Testing was just underway at the end of this period.

Drug Control: High Intensity Drug Trafficking Areas' Efforts to Link Investigations to International Drug Traffickers
A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2002, the Attorney General called upon law enforcement to target the "most wanted" international drug traffickers responsible for supplying illegal drugs to America. In September 2002, law enforcement, working through the multi-agency Organized Crime Drug Enforcement Task Force (OCDETF) Program, developed a list of these drug traffickers, known as the Consolidated Priority Organization Target List (CPOT), to aid federal law enforcement agencies in targeting their drug investigations. Also, the White House's Office of National Drug Control Policy (ONDCP) collaborated with law enforcement to encourage existing High Intensity Drug Trafficking Areas (HIDTA) to conduct CPOT investigations. According to ONDCP, the 28 HIDTAs across the nation are located in centers of illegal drug production, manufacturing, importation, or distribution. ONDCP distributed discretionary funds to supplement some HIDTAs' existing budgets beginning in fiscal year 2002 to investigate CPOT organizations. Out of concern that a CPOT emphasis on international drug investigations would detract from the HIDTA program's regional emphasis, the Senate Committee on Appropriations directed GAO to examine whether investigations of CPOT organizations are consistent with the HIDTA program's mission and how ONDCP distributes its discretionary funds to …

The Economics of the Federal Budget Deficit
In FY1998, federal budget receipts exceeded outlays for the first time since 1969. Those surpluses continued through FY2001. At one time, those surpluses had been projected to continue, but conditions have since changed. The economy went into recession in 2001, and a stimulus package was enacted. Since then, the budget has been in deficit. The actual unified budget deficit for FY2004 was $412.1 billion. In January 2005, the Congressional Budget Office projected that there would be a budget deficit of $368 billion in FY2005, and a deficit of $295 billion in FY2006.

Energetics of Nanomaterials
This project, "Energetics of Nanomaterials," represents a three-year collaboration among Alexandra Navrotsky (UC Davis), Brian Woodfield and Juliana Boerio-Goates (BYU), and Frances Hellman (UC Berkeley). It's purpose has been to explore the differences between bulk materials, nanoparticles, and thin films in term of their thermodynamic properties, with an emphasis on heat capaacities and entropies, as well as enthalpies. the three groups have brought very different expertise and capabilities to the project. Navrotsky is a solid-state chemist and geochemist, with a unique Thermochemistry Facility emphasizing enthalpy of formation measurements by high temperature oxide melt and room temperatue acid solution calorimetry. Boerio-Goates and Woodfield are calorimetry. Hellman is a physicist with expertise in magnetism and heat capacity measurements using microscale "detector on a chip" calorimetric technology that she pioneered. The overarching question of our work is "How does the free energy play out in nanoparticles?", or "How do differences in free energy affect overall nanoparticle behavior?" Because the free energy represents the temperature-dependent balance between the enthalpy of a system and its entropy, there are two separate, but related, components to the experimental investigations: Solution calorimetric measurements provide the energetics and two types of heat capacity measurements the entropy. We use materials …
