Harnessing Knowledge to Ensure Food Safety: Opportunities to Improve the Nation\u27s Food Safety Information Infrastructure

Those working in the food industry face an abundance of information generated by diverse institutions and individuals. Ensuring the safety of food is critically important to the public\u27s health and a challenge for policy-makers seeking to enhance the government\u27s role in this arena. Although the food industry has an inherent duty to make food safe, the effectiveness of what they do is highly dependent on the quality of the information they receive on potential hazards and good practices. In this context, the Robert Wood Johnson Foundation funded a project under the auspices of the Food Safety Research Consortium to examine and make recommendations for improving the food safety information infrastructure (FSII). Through this initiative, a collection of food safety experts met for a series of workshops to discuss information needs around food safety. Key Findings: Establish a national FSII policy and program. Build a database for tracking research and data collection. Provide broader public access to journal articles and to complete data from research projects. Create a networking Web site. In this report, whose recommendations are based on those workshop discussions, the authors explore the constraints facing today\u27s FSII. These include the diversity of the information currently available, the plethora of information sources, and the numerous agencies and actors involved in generating data

Fundamental constraints on particle tracking with optical tweezers

A general quantum limit to the sensitivity of particle position measurements is derived following the simple principle of the Heisenberg microscope. The value of this limit is calculated for particles in the Rayleigh and Mie scattering regimes, and with parameters which are relevant to optical tweezers experiments. The minimum power required to observe the zero-point motion of a levitating bead is also calculated, with the optimal particle diameter always smaller than the wavelength. We show that recent optical tweezers experiments are within two orders of magnitude of quantum limited sensitivity, suggesting that quantum optical resources may soon play an important role in high sensitivity tracking applications

Portable dynamic fundus instrument

A portable diagnostic image analysis instrument is disclosed for retinal funduscopy in which an eye fundus image is optically processed by a lens system to a charge coupled device (CCD) which produces recordable and viewable output data and is simultaneously viewable on an electronic view finder. The fundus image is processed to develop a representation of the vessel or vessels from the output data
