Curators' Evaluation of WAS Release 1

Description: This report discusses the curators' evaluation of Web Archiving Service (WAS) release 1, as part of the Web-at-Risk project. This report summarizes the feedback received from the curators and provides details details to illustrate the areas that were either confusing or problematic to them. Their recommendations as well as some considerations for future development are also included. Additionally, many of the observations and suggestions in the Quick Heuristic Evaluation of the WAS echo the feedback received from the curators. These commonalities are noted in the document.

Spatiotemporal Wave Patterns: Information Dynamics

Description: Pattern formation has traditionally been studied in non-equilibrium physics from the viewpoint of describing the basic structures and their interactions. While this is still an important area of research, the emphasis in the last few years has shifted towards analysis of specific properties of patterns in various complex media. For example, diverse and unexpected phenomena occur in neuro-like media that are characterized by highly non-trivial local dynamics. We carried out an active research program on analysis of spatio-temporal patterns in various physical systems (convection, oscillating fluid layer, soap film), as well as in neuro-like media, with an emphasis on informational aspects of the dynamics. Nonlinear nonequilibrium media and their discrete analogs have a unique ability to represent, memorize, and process the information contained in spatio-temporal patterns. Recent neurophysiological experiments demonstrated a certain universality of spatio-temporal representation of information by neural ensembles. Information processing is also revealed in the spatio-temporal dynamics of cellular patterns in nonequilibrium media. It is extremely important for many applications to study the informational aspects of these dynamics, including the origins and mechanisms of information generation, propagation and storage. Some of our results are: the discovery of self-organization of periodically oscillatory patterns in chaotic heterogeneous media; the analysis of the propagation of the information along a chaotic media as function of the entropy of the signal; the analysis of wave propagation in discrete non-equilibrium media with autocatalytic properties, which simulates the calcium dynamics in cellular membranes. Based on biological experiments we suggest the mechanism by which the spatial sensory information is transferred into the spatio-temporal code in the neural media. We also found a new mechanism of self-pinning in cellular structures and the related phenomenon of stick-slip front motion.

Phytoremediation of Ionic and Methylmercury Pollution

Description: Phytoremediation is defined as the use of plants to extract, resist, detoxify, and/or sequester toxic environmental pollutants. The long-term goal of the proposed research is to develop and test highly productive, field-adapted plant species that have been engineered for the phytoremediation of mercury. A variety of different genes, which should enable plants to clean mercury polluted sites are being tested as tools for mercury phytoremediation, first in model laboratory plants and then in potential field species.

China-U.S. Relations: Current Issues and Implications for U.S. Policy

Description: The bilateral relationship between the U.S. and the People's Republic of China (PRC) is vitally important, touching on a wide range of areas including, among others, economic policy, security, foreign relations, and human rights. This report addresses relevant policy questions in current U.S.-China relations, discusses trends and key legislation in the current Congress, and provides a chronology of developments and high-level exchanges.

Wireless Technology and Spectrum Demand: Advanced Wireless Services

Description: Advances in wireless telecommunications technology are converging with Internet technology to foster new generations of applications and services. Presently, the United States and other countries are moving to third-generation (3G) and fourth-generation mobile telephony. The defining feature of these technologies is that transmission speeds are significantly faster than prevailing technologies. A related trend is the growth in use of Wi-Fi (wireless fidelity) and WiMAX (an industry designation for a specific broadband standard). This report describes various legislation relating to this expansion and ongoing telecommunications development.

Exempting Food and Agriculture Products from U.S. Economic Sanctions: Status and Implementation

Description: Falling agricultural exports and declining commodity prices led farm groups and agribusiness firms to urge the 106th Congress to pass legislation exempting foods and agricultural commodities from U.S. economic sanctions against certain countries. In completing action on the FY2001 agriculture appropriations bill, Congress codified the lifting of unilateral sanctions on commercial sales of food, agricultural commodities, medicine, and medical products to Iran, Libya, North Korea, and Sudan, and extended this policy to apply to Cuba (Title IX of H.R. 5426, as enacted by P.L. 106-387; Trade Sanctions Reform and Export Enhancement Act of 2000). Related provisions place financing and licensing conditions on sales to these countries. Those that apply to Cuba, though, are permanent and more restrictive than for the other countries. Other provisions give Congress the authority in the future to veto a President's proposal to impose a sanction on the sale of agricultural or medical products.

Foreign Policy Budget Trends: A Thirty-Year Review

Description: This report serves as a resource for the annual congressional debate on foreign policy spending, providing context and a trend analysis of the past 30 years. It considers the full scope of the International Affairs Budget, or Budget Function 150, as foreign policy spending is designated within the context of the Congressional Budget Resolution. It also illustrates spending trends of the major components that make up Budget Function 150. Other relevant “snapshots” of international spending are also examined, including how foreign aid resources have been allocated across several sub-categories and trends that are especially applicable to current funding priorities such as confronting global health problems and increasing aid to Africa.
