By MURRAY WEINER, M.D., KURT ZELTMACHER, M.D., CARL REICH, M.D., AND SHEPARD SHAPIRO, M.D. I N 1941, Helen Wright’ described a method for estimating the adhesive quality of platelets. Confirmation of the original findings by Spooner and Meyer’ established the procedure as a means of distinguishing this property of platelets. It is the purpose of the present report to evaluate the usefulness of ...

This memo is an introductory guide to many of the most commonly-available TCP/IP and Internet tools and utilities. It also describes discussion lists accessible from the Internet, ways to obtain Internet and TCP/IP documents, and some resources that help users weave their way through the Internet. RFC 2151 Internet & TCP/IP Tools & Utilities May 1997 Kessler & Shepard Informational [Page 2] Tab...

We present a uniied approach to visual representation, addressing both the needs of superordinate and basic-level categorization and of identiication of speciic instances of familiar categories. According to the proposed theory, a shape is represented by its similarity to a number of reference shapes, measured in a high-dimensional space of elementary features. This amounts to embedding the sti...

We propose an attractor neural network (ANN) model that performs rotation-invariant pattern recognition in such a way that it can account for a neural mechanism being involved in the image transformation accompanying the experience of mental rotation. We compared the performance of our ANN model with the results of the chronometric psychophysical experiments of Cooper and Shepard (Cooper L A an...

Drawing by E H Shepard (1948) (Reproduced by permission of the, estate of E H Shepard) In retrospect it is clear that those who fought Nye Bevan's plans for setting up the National Health Service were right in at least one important respect. The setting up in 1948 marked a revolution in the relation between the state and the medical profession. But it was not quite the revolution that the criti...

Wireless sensor networks (WSNs) typically gather data at a discrete number of locations. However, it is desirable to be able to design applications and reason about the data in more abstract forms than in points of data. By bestowing the ability to predict inter-node values upon the network, it is proposed that it will become possible to build applications that are unaware of the concrete reali...
