Rapid Evaluation

The evaluation of Coulombic or gravitational interactions in large ensembles of particles is an integral part of the numerical simulation of a large number of physical processes. Examples include celestial mechanics, plasma physics, the vortex method in fluid dynamics, molecular dynamics, molecular dynamics, and the solution of the Laplace equation via potential theory. A numerical model follows the trajectories of a number of particles moving in accordance with Newton's second law of motion in a field generated by the whole ensemble. In many situations, in order to be of physical interest, the simulation has to involve thousands of particles (or more), and the fields have to be evaluated for a large number of configurations. Unfortunately, an amount of work of the order O N-sg has traditionally been required to evaluate all pairwise interactions in a system of N particles, unless some approximation or truncation method is used. Large scale simulations have been extremely expensive in some cases, and prohibitive in others. An algorithm is presented for the rapid evaluation of the potential and force fields in large scale systems of particles. To evaluate all pairwise Coulombic interactions of N particles to within round off error, the algorithm requires an amount of work proportional to N, and this estimate does not depend on the statistics of the distribution. Both two and three dimensional versions of the algorithm have been constructed. Applications to several problems in physics, chemistry, biology, and numerical complex analysis are discussed.

This book introduces basic ROSE techniques and resources required to set up ROSE service. It reviews the cytomorphologic features that are recognizable during ROSE, including those important for sample adequacy, specimen triage, preliminary interpretation, and potential diagnostic pitfalls. Economic and regulatory aspects are discussed as well as the pros and cons of telecytology. The book is formatted for clinical settings, simulating the ROSE process that occurs in the ultrasound room, CT room, bronchoscopy suite, and endoscopy suite. Each chapter focuses on the cytomorphologic clues and pitfalls of the entities specific to that clinical setting. Rapid On-Site Evaluation: A Practical Guide will be a valuable resource for pathologists, cytotechnologists, physicians who perform biopsies and/or ROSE evaluation, and trainees for utilizing ROSE and improving diagnostic performance of biopsies.

Wetland and Stream Rapid Assessments: Development, Validation, and Application describes the scientific and environmental policy background for rapid wetland and stream assessments, how such assessment methods are developed and statistically verified, and how they can be used in environmental decision-making—including wetland and stream permitting. In addition, it provides several case studies of method development and use in various parts of the world. Readers will find guidance on developing and testing such methods, along with examples of how these methods have been used in various programs across North America. Rapid wetland and stream functional assessments are becoming frequently used methods in federal, state and local environmental permitting programs in North America. Many governments are interested in developing new methods or improving existing methods for their own jurisdictions. This book provides an ideal guide to these initiatives. Offers guidance for the use and evaluation of rapid assessments to developers and users of these methods, as well as students of wetland and stream quality Contains contributions from sources who are successful in academia, industry and government, bringing credibility and relevance to the content Includes a statistically-based approach to testing the validity of the rapid method, which is very important to the usefulness and defensibility of assessment methods

In today's time-pressured managed care environment, it is important for clinicians to quickly identify the nature of a patient's problem and initiate treatment. With thousands of psychological instruments available, this can often be difficult. This book offers a form of psychological assessment "triage." It eliminates the guesswork and helps psychologists quickly select, administer, and interpret psychological tests.
