 | There are two main issues in costing future systems: 1) Determine how much and who pays for shared data and services in future net-centric programs. 2) Determine cost implications of including training plans early in the JCIDS and Acquisition processes. DoD has no established process (or understanding of need?) for sponsoring enterprise-level efforts. Net-centric environments of the future will require more sharing of infrastructure, data and models |

|
| The critical problem of CFD is perhaps an accurate approximation of derivatives for a given discrete data set. Based on our previous work on the weighted compact scheme (WCS), a modified weighted compact scheme (MWCS) has been developed. Similar to WENO, three high order candidates, left, right, and central, are constructed by Hermite polynomials. |

 | In 1996 Congress amended the Foreign Sovereign Immunities Act (FSIA) to allow U.S. victims of terrorism to sue designated State sponsors of terrorism for their terrorist acts. The courts have handed down large judgments against the terrorist State defendants, generally in default, and successive Administrations have intervened to block the judicial attachment of frozen assets to satisfy judgments. After a court ruled that Congress never created a cause of action ... |

| To protect the U.S. industrial base during periods of adversity and war, Congress passed domestic source restrictions as part of the 1941 Fifth Supplemental Department of Defense (DoD) Appropriations Act; these provisions later became the Berry Amendment. The Berry Amendment requires DoD to give preference in procurement to domestically produced, manufactured, or home-grown products, notably food, clothing, fabrics, and specialty metals. The Berry Amendment (Title 10 U.S.C. Section 2533a) contains ... |

| U.S. and outside assessments of the effort to stabilize Afghanistan are mixed and subject to debate; the Administration notes progress on reconstruction, governance, and security in many areas of Afghanistan, particularly the U.S.-led eastern sector of Afghanistan. However, a November 2007 Bush Administration review of U.S. efforts in Afghanistan reportedly concluded that overall progress was inadequate. This mirrors recent outside studies that contain relatively pessimistic assessments, emphasizing a growing sense ... |

| Burkholderia pseudomallei and its host-adapted deletion clone Burkholderia mallei, cause the potentially fatal human diseases melioidosis and glanders, respectively. Their antibiotic resistance profile, ability to infect via aerosol, and the absence of protective vaccines has led to their classification as major biothreats and select agents. Although documented infections by these bacteria date back over 100 years, relatively little is known about their virulence and pathogenicity mechanisms. We used in silico ... |
