Algorithmic aspects of a neuron for coherent wave synapse realizations.

We study a neuron functional form (which we call the absolute value neuron) that arises naturally in analog devices in which the neuron synapses are realized using coherent oscillatory wave signals. We discuss algorithmic aspects of this neuron at both the single neuron and network level, including computational capabilities, generalization, and training. A numerical study of absolute value neural networks on two data sets is presented, which demonstrates performance competitive with standard neural networks.

Collaboration: the solution to multidisciplinary care planning.

Case management is a patient care delivery system that is transforming health care in the 1990s. The key to its success is its primary tenet of collaboration among all disciplines. Case management enhances communication among all disciplines and coordinates patient care services. Multidisciplinary action plans have been developed as a tool for the multidisciplinary team, to guide health care practitioners toward the highest quality, cost-effective care possible. At Beth Israel Medical Center in New York City, the Multidisciplinary Care Model has proven successful on both the Orthopaedic and Rehabilitation services.

Fully automated preparation of high-quality stained blood films.

A detailed description is given of the operation of Technicon's AutoSlide, which automatically produces a microscope-ready, precipitate-free, stained blood smear with superior cell distribution and good morphology. A 40-test-tube turntable carrying anticoagulated blood inputs samples at 40-second intervals. The blood films are drawn consecutively on a continuous Mylar substrate, with nylon mesh replacing the usual glass slide spreaders. This flexible substrate then passes through drying, fixing, staining and final drying stations. The methanol of conventional Romanowsky stains is replaced by low-volatility solvents. The fixing solution contains solvents, toluidine blue O, glutaraldehyde and a trace of water. The modified Giemsa-stain stock, when mixed with buffer, remains precipitate free for several days. Finally the blood film is imprinted with a date and identification number. Liquid monomer is dispensed onto each stained blood film, followed by a microscope slide. The monomer is then polymerized using ultraviolet light. Permanent transfer of the stained and labeled blood film occurs when the Mylar is stripped from the slide. The usable area for examination is approximately five times larger than that of a typical manual wedge smear.
