Simulation-based methods for statistical inference have evolved dramatically over the past 50 years, keeping pace with technological advancements. The field is undergoing a new revolution as it embraces the representational capacity of neural networks, optimization libraries, and graphics processing units for learning complex mappings between data and inferential targets. The resulting tools are amortized, in the sense that, after an initial setup cost, they allow rapid inference through fast feed-forward operations. In this article we review recent progress in the context of point estimation, approximate Bayesian inference, summary-statistic construction, and likelihood approximation. We also cover software and include a simple illustration to showcase the wide array of tools available for amortized inference and the benefits they offer over Markov chain Monte Carlo methods. The article concludes with an overview of relevant topics and an outlook on future research directions.

The field of optics has been accelerating at an unprecedented rate, due both to the tremendous growth of the field of fiber-optic communications, and to the improvement of optical materials and devices. Throughput capabilities of fiber systems are accelerating faster than Moore's law, the famous growth rate of silicon chip capability, which has propelled that industry relentlessly over decades. In addition, new optical storage techniques push the limits of information density, with an ever decreasing cost per bit of storage. Economic investment in photonics is at an all-time high. At the same time, other fields of optics, adaptive optics for instance, are bringing new capabilities to more classical applications such as astronomical imaging. New lasers continue to be developed, with applications in display, sensing, and biomedicine following at ever-shorter intervals after the initial discoveries. Given this background, the NATO Mediterranean Dialog Advanced Research Workshop on Unconventional Optical Elements for Information Storage, Processing and Communications, held in Israel on October 19-21, 1998, came at an opportune moment in the history of optics. Its aim was to overview the current state-of-the-art and encourage cooperation in the Mediterranean region, with a view to highlighting and enhancing the existing potential for further development and innovation. The workshop included participants from Belgium, France, Germany, Greece, Israel, Italy, Jordan, Morocco, Portugal, Romania, Russia, Switzerland, Turkey, United Kingdom and USA.

FROSCH, ROBERT A.Robert A. Frosch was appointed Assistant Secretary of the Navy for Research and Development on July 1
1966. In this capacity he is responsible for formulation and management of the Navy's Research Development Test and Evaluation program. In addition he is responsible for policy guidance of Navy work in Oceanography. In July 1966 he was designated Chairman of the Interagency Committee on Oceanography
which was reconstituted in July 1967 as the Interagency Committee on Marine Research Education and Facilities (ICMREF). This Committee reports directly to the National Council on Marine Resources and Engineering Development chaired by the Vice President. As Chairman of ICMREF Dr. Frosch has contributed to the national oceanographic program and to the Navy's role in ocean sciences and engineering. In November 1967 Dr. Frosch was Chairman of the United States Delegation to the Fifth Session of the Intergovernmental Oceanographic Commission which met in Paris. Dr. Frosch entered Government service in 1963 when he joined the Department of Defense as Director of Nuclear Test Detection (Project VELA)
Advanced Research Projects Agency. In 1965 he became Deputy Director of the Advanced Research Projects Agency and remained in that position until becoming Assistant Secretary of the Navy. Prior to completing graduate work
Dr. Frosch joined Hudson Laboratories of Columbia University in 1951 as a scientist. He held various positions of increasing responsibility until appointed Director in 1956 which position he held until 1963. While at Hudson Laboratories he was involved in cooperative research with the Office of Naval Research on projects in underwater sound and related marine matters applicable to undersea warfare. He took part in various seagoing research projects. He served as a member of various anti-submarine warfare and oceanographic advisory committees to the Navy and to the Department of Defense. He has written numerous scientific and technical articles. In early 1966 Dr. Frosch received the Arthur S. Flemmin

HARRISON, CHARLES W.COMMANDER CHARLES W. HARRISON
JR. USN attended the U. S. Naval Academy Preparatory School the U. S. Coast Guard Academy and the University of Virginia where in 1939 he received the S.B. degree in Engineering and in 1940 the degree of Electrical Engineer. In 1942 he was graduated with the S.M. degree in Communication Engineering from Cruft Laboratory Harvard University and that summer completed the Navy Course in Radar Engineering at Massachusetts Institute of Technology. Subsequently for several years he was engaged in lecturing to officers of the Armed Forces assigned to the radar schools at Harvard and Princeton Universities. He has had four tours of duty in the Electronics Design and Development Division Bureau of Ships two at the U.S. Naval Research Laboratoryone at the Signal Corps Engineering Laboratories (Evans Signal Laboratory)and one at the Philadelphia Naval Shipyard. His experience includes amateur
naval and broadcasting operation. In 1951 Commander Harrison was selected for training in Advanced Science at Harvard University under sponsorship of the Office of Naval Research. This program led to the M. Eng. degree in 1952 and Ph.D. degree in Applied Physics in 1954. Commander Harrison is presently Electronics Officer on the Staff of Commander Operational Development Force. He is a member of several societies and associations including the Harvard Chapter of the Society of Sigma Xi.
Summary: The measurement of the magnetic field associated with a linearly or elliptically polarized electric field, using a small loop, or magnetic probe, is discussed. It is shown that in general a loop will not meas...
