Visual acuity is analyzed in terms of the retinal ganglion cell response to different stimuluses on the receptor matrix. The antagonism between the central and peripheral responses of the ganglion cell receptive field is shown to effect both the sensitivity profile and the Ricco field (Area X Intensity) response. The difficulties with each method of analyzing the receptive field are discussed and an experimental protocol is formulated which derives information by comparisons between the...

The organization of the retina was investigated with regard to visual acuity. In particular, the receptive fields of the ganglion cells were analyzed and described in terms of, primarily, their anatomical relations to each other, i.e., receptor spacing and secondly, the neural organization. In a typical eye (cat) the sensitivity to angular separation on the basis of anatomical makeup has an upper limit of 8 cycles per degree for acuity. On the other hand, it is predicted that, for neural...

Low observable (LO) aircraft and cruise missiles give U.S. military forces the technical capability to successfully attack well-defended ground targets with substantially reduced risk of engagement by enemy defenses.

Visual acuity depends upon three components: the image upon the retina, the dissection of this image by the retina, and the processing of the signals from the receptors by the visual system. The limitations upon the image on the retina imposed by the optical system of the eye and the wave nature of light are summarized. The receptor mosaic is related to the retinal image by point spread functions for both monochromatic and white light. The image on the retina and receptor mosaic are reviewed as...

Establishment of the profit or management fee paid to a Department of Defense contractor is governed by the Department's weighted guidelines profit policy.

The antibody response of recruits to the standard trivalent influenza vaccine for the 1989 - 1990 season was excellent to all three components. In particular, the response to the B component was unusually good, when compared to previous years. In contrast, the response of the permanent part was not as strong, with 34% failing to reach protective titers against the HlNl antigen, and 10-12% unprotected against the other two components. Cell-mediated immunity to the influenza vaccine was measured...

Until recently, the privately owned U.S. flag merchant fleet provided sufficient numbers of dry cargo ships to transport military unit equipment (u/e) . In the past decade, however, the number of dry cargo ships in this fleet decreased by approximately one-third, from more than 300 to about 200. Equally important, the direct military utility of this fleet decreased substantially because of the increased proportion of container ships. Today, the fleet includes about 94 pure container ships,...

When using a mass spectrometer to monitor free radical and atom intermediates in rapid gas-phase reactions, identification of the parent species of each ion is made difficult by fragmentation processes that occur at electron energies necessary for optimum ionization cross sections. Molecular beam analysis is a new approach to this problem whereby molecular beam measurements are used to characterize neutral species before they are ionized. Thus, the trajectory of a particle in an inhomogeneous...

For typical engineering materials there is little difference between the results obtained from this solution and the earlier ones obtained from...
