In a security alliance since 2004 and "strategic partners" since 2006, the United States and Pakistan for decades experienced major shifts in the nature and tone of their relations. In the post- 9/11 period, assisting in the creation of a more stable, democratic, and prosperous Pakistan actively combating religious militancy has been among the most important U.S. foreign policy efforts. Pakistan is among the leading recipients of U.S. aid in the post-9/11 period, having been appropriated about $24 billion in assistance and military reimbursements since 2001. FY2013 legislation in the 112th Congress would cut U.S. assistance funding significantly from both the levels requested by the Administration and from those Congress approved for FY2012. Provisions also would introduce more rigorous restrictions and certification requirements on such aid. With anti-American sentiments and xenophobic conspiracy theories rife among ordinary Pakistanis, persistent economic travails and a precarious political setting combine to present serious challenges to U.S. decision makers.

This report focuses on the current situation with spent nuclear fuel storage in the United States. It does not address all of the issues associated with permanent disposal of SNF, but rather focuses on the SNF storage situation, primarily at current and former reactor facilities for the potentially foreseeable future.

Issues regarding the Congressional appeal of the January 27, 2010 SEC-published 'Commission Guidance Regarding Disclosure Related to Climate Change', which clarifies how publicly traded corporations should apply existing SEC disclosure rules to certain mandatory financial filings with the SEC regarding the risk that climate change developments may have on their businesses.

Systemic risk refers to the possibility that the financial system as a whole might become unstable, rather than the health of individual market participants. Stable financial systems do not transmit or magnify shocks to the broader economy. A firm, person, government, financial utility, or policy might create systemic risk if (1) its failure causes other failures in a domino effect; (2) news about its assets signals that others with similar assets may also be distressed, called contagion; (3) it contributes to fire sales during price declines; or (4) its absence prevents other firms from using an essential service, called critical functions. This report discusses how systemic risk may apply to JP Morgan's recent losses.

Syria remains mired in political confrontation and violence, and is perched on the edge of civil war. U.S. officials and many analysts believe that President Bashar al Asad, his family members, and his supporters will ultimately be forced from power. President Obama and his Administration have been calling for Asad's resignation since August 2011, and have been vocal advocates for United Nations Security Council action to condemn the Syrian government and end the bloodshed. The United States has closed its embassy in Damascus, and Ambassador Robert Ford has left Syria. In the face of intense domestic and international pressure calling for political change and for an end to violence against civilians, the Asad government has offered limited reforms while also meeting protests and armed attacks with overwhelming force. After a year of unrest and violence, Syria's political crisis is characterized by dilemmas and contradictions, which are discussed in this report.

Testimony issued by the Government Accountability Office with an abstract that begins "As discussed in our report, OMB and key federal agencies have made progress on selected action items identified in the IT Reform Plan, but there are several areas where more remains to be done. Of the 10 key action items we reviewed, 3 were completed and the other 7 were partially completed by December 2011. The action items that are behind schedule share a common reason for the delays: the complexity of the initiatives. In all seven of the cases, OMB and the federal agencies are still working on the initiatives. However, OMB and federal agencies have established time frames for completing only two of these initiatives."

Correspondence issued by the Government Accountability Office with an abstract that begins "During our fiscal year 2011 audit, we identified eight new general information systems control deficiencies related to access controls, configuration management, and segregation of duties. We made nine recommendations to address these control deficiencies. In a separately issued Limited Official Use Only report, we communicated to BPD management detailed information regarding our findings and related recommendations."

Correspondence issued by the Government Accountability Office with an abstract that begins "DOD officials are seeking to approach strategic communication as a process that leaders, planners, and operators should follow to integrate foreign audience perceptions into policy making, planning, and operations at every level. However, descriptions of strategic communication in several key documents—including the Quadrennial Defense Review and the National Framework for Strategic Communication—characterize it differently. For example, the Quadrennial Defense Review describes strategic communication as the coordination of activities such as information operations and public affairs, among other things. According to DOD officials, these varying descriptions of strategic communication have created confusion within the department. To address this confusion, DOD is drafting an instruction to clarify the steps of the strategic communication process, which DOD officials expect to be completed in late spring or early summer 2012."

A letter report issued by the Government Accountability Office with an abstract that begins "HUD’s fiscal year 2011 expenditure plan, which seeks to obligate about $114 million for seven modernization projects, along with enterprisewide services and program management, satisfies both sets of statutory conditions contained in the 2011 appropriations act. Specifically, for the first set of statutory conditions, the plan identified the functional and performance capabilities, mission benefits, lifecycle costs, and key milestones for each of the projects. For example, the plan described specific and measurable mission benefits associated with HUD’s Place-Based Performance Management System project, such as reducing the time to compile performance information from 50 hours to 20 hours. In addition, the plan described costs associated with the lifecycle of each project, providing details on funds needed for major work activities."

The Small Gram Quantity (SGQ) concept is based on the understanding that the hazards associated with the shipment of a radioactive material are directly proportional to its mass. This study describes a methodology that estimates the acceptable masses for several neutron and gamma emitting isotopes that can be shipped in a 9977 Package compliant with the Title 10 of the Code of Federal Regulations, Part 71 (10CFR71) external radiation level limits. 10CFR71.33 states that a shipping application identifies the radioactive and fissile materials at their maximum quantity and provides an evaluation demonstrating compliance with the external radiation standards. Since rather small amounts of some isotopes emit sufficiently strong radiation to produce a large external dose rate, quantifying of the dose rate for a proposed content is a challenging issue for the SGQ approach. It is essential to quantify external radiation levels from several common gamma and neutron sources that can be safely placed in a specific packaging, to ensure compliance with federal regulations. A methodology was established for determining the dose rate for bounding mass limits for a set of isotopes in the Model 9977 Shipping Package. Calculations were performed to estimate external radiation levels using the MCNP radiation transport …

The Large Synoptic Survey Telescope (LSST) uses a novel, three-mirror, telescope design feeding a camera system that includes a set of broad-band filters and three refractive corrector lenses to produce a flat field at the focal plane with a wide field of view. Optical design of the camera lenses and filters is integrated in with the optical design of telescope mirrors to optimize performance. We discuss the rationale for the LSST camera optics design, describe the methodology for fabricating, coating, mounting and testing the lenses and filters, and present the results of detailed analyses demonstrating that the camera optics will meet their performance goals.

Nuclear weapon arms control treaty verification is a key aspect of any agreement between signatories to establish that the terms and conditions spelled out in the treaty are being met. Historically, arms control negotiations have focused more on the rules and protocols for reducing the numbers of warheads and delivery systems - sometimes resorting to complex and arcane procedures for counting forces - in an attempt to address perceived or real imbalances in a nation's strategic posture that could lead to instability. Verification procedures are generally defined in arms control treaties and supporting documents and tend to focus on technical means and measures designed to ensure that a country is following the terms of the treaty and that it is not liable to engage in deception or outright cheating in an attempt to circumvent the spirit and the letter of the agreement. As the Obama Administration implements the articles, terms, and conditions of the recently ratified and entered-into-force New START treaty, there are already efforts within and outside of government to move well below the specified New START levels of 1550 warheads, 700 deployed strategic delivery vehicles, and 800 deployed and nondeployed strategic launchers (Inter-Continental Ballistic Missile (ICBM) silos, Submarine-Launched …

A new method for the determination of radiostrontium in large soil samples has been developed at the Savannah River Environmental Laboratory (Aiken, SC, USA) that allows rapid preconcentration and separation of strontium in large soil samples for the measurement of strontium isotopes by gas flow proportional counting. The need for rapid analyses in the event of a Radiological Dispersive Device (RDD) or Improvised Nuclear Device (IND) event is well-known. In addition, the recent accident at Fukushima Nuclear Power Plant in March, 2011 reinforces the need to have rapid analyses for radionuclides in environmental samples in the event of a nuclear accident. The method employs a novel pre-concentration step that utilizes an iron hydroxide precipitation (enhanced with calcium phosphate) followed by a final calcium fluoride precipitation to remove silicates and other matrix components. The pre-concentration steps, in combination with a rapid Sr Resin separation using vacuum box technology, allow very large soil samples to be analyzed for {sup 89,90}Sr using gas flow proportional counting with a lower method detection limit. The calcium fluoride precipitation eliminates column flow problems typically associated with large amounts of silicates in large soil samples.

A method is presented for calculating the high-frequency longitudinal and transverse coupling impedances in a periodic array of diaphragms in a circular perfectly conducting pipe. The method is based on Weinstein's theory of diffraction of a plane electromagnetic wave on a stack of halfplanes. Using Weinstein's solution, it is shown that the problem of finding the beam field in the pipe reduces to an effective boundary condition at the radius of the diaphragms that couples the longitudinal electric field with the azimuthal magnetic one. Solving Maxwell's equations with this boundary condition leads to simple formulae for Z{sub long} and Z{sub tr}. A good agreement with a numerical solution of the problem found by other authors is demonstrated.

This poster reports progress related to photonic technologies. Specifically, the authors developed diagnostic system architecture for a Multiplexed Photonic Doppler Velocimetry (MPDV) that incorporates frequency and time-division multiplexing into existing PDV methodology to provide increased channel count. Current MPDV design increases number of data records per digitizer channel 8x, and also operates as a laser-safe (Class 3a) system. Further, they applied heterodyne interferometry to allow for direction-of-travel determination and enable high-velocity measurements (>10 km/s) via optical downshifting. They also leveraged commercially available, inexpensive and robust components originally developed for telecom applications. Proposed MPDV architectures employ only commercially available, fiber-coupled hardware.

When the burn-up is high, the {sup 242}Pu isotopic content becomes more important. The traditional correlation method will fail. The {sup 242}Pu isotopic content in the sample plays an essential role if the neutron coincidence method is used to quantify the total amount of plutonium. In one of the earlier measurements we had a chance to measure an isotopic pure (> 99.95 %) {sup 242}Pu thick sample and realized that the difference in the branching ratio (BR) value among current nuclear data3) for the two important gamma-rays at 103.5-keV and 158.8-keV. In this study, the thick sample was counted on a 15% ORTEC safeguards type HPGe to further improve BR determination of the 159-keV gamma-ray. Furthermore, we have made a thin {sup 242}Pu sample from the thick sample and performed alpha-gamma coincidence measurements. Our preliminary gamma-ray BR results are 4.37(6) E-4, 2.79(8) E-5, and 2.25(8) E-6 for 44.9-keV, 103.5-keV, and 158.9-keV, respectively.

The overall objective is to create robust artificial protein modules as scaffolds to control both (a) the conformation of novel cofactors incorporated into the modules thereby making the modules possess a desired functionality and (b) the organization of these functional modules into ordered macroscopic ensembles, whose macroscopic materials properties derive from the designed microscopic function of the modules. We focus on two specific types of cofactors for imparting functionality in this project; primarily nonlinear optical (NLO) chromophores designed to exhibit extraordinary molecular hyperpolarizabilities, as well as donor-bridge-acceptor cofactors designed to exhibit highly efficient, 'through-bonds' light-induced electron transfer (LIET) over nano-scale distances. The ensembles range from 2-D to 3-D, designed to possess the degree of orientational and positional order necessary to optimize their macroscopic response, the latter ranging from liquid-crystalline or glass-like to long-range periodic. Computational techniques, firmly based in statistical thermodynamics, are utilized for the design the artificial protein modules, based on robust {alpha}-helical bundle motifs, necessarily incorporating the desired conformation, location, and environment of the cofactor. Importantly, this design approach also includes optimization of the interactions between the modules to promote their organization into ordered macroscopic ensembles in 2-D and 3-D via either directed-assembly or self-assembly. When long-range periodic …
