26 Davidson, Diane W.Ecological studies of neotropical ant-gardensIn a census taken in Peru's Manu National Park, 10 epiphytic angiosperms from seven plant families established principally on arboreal carton-ant nests. These "ant gardens" (AGs) were most often inhabited by parabiotic ants, Camponotus femoratus and Crematogaster cf. limata parabiotica, whose polygy...Ant competition; Ant garden; Ant-plant interaction; Coadaptation; Epiphyte; Mutualism; Parabiosis; Preadaptation; Peru; Seed dispersal; Tropical rainforest1988
27 Hansen, Charles D.Efficient depth estimation using trinocular stereoWe present recent advancements in our passive trinocular stereo system. These include a technique for calibrating and rectifying in a very efficient and simple manner the triplets of images taken for trinocular stereovision systems. After the rectification of images, epipolar lines are parallel to t...Trinocular stereo; Stereovision1988
28 Firmage, Edwin B.Ends and meansSince the advent of the atomic era, the United States has decided to wage war by covert means, intervening secretly in the election, selection and direction of governments in other countries. Our weapons are subversive propaganda, including "black" propaganda and disinformation; undermining the econ...Prados, John; Cockburn, Leslie; Treverton, Gregory; Covert wars; Central Intelligence Agency; CIA1988
29 Firmage, Edwin B.Ends and means in conflictA great danger of our time is our intense preoccupation with the ends we seek, so much so that we have overlooked the effect, usually and perhaps always the determinative effect, that our choice of means will have made upon the nature of those ends. This problem is made more difficult in that our vi...Weapons proliferation; Arms race; Atomic weapons1988
30 Armentrout, Peter B.Energetics and dynamics in the reaction of Si+ with SiF4. Thermochemistry of SiFx and SiFx+ (x=1,2,3)The title reaction is studied using guided ion beam mass spectrometry. Absolute reaction cross sections are measured as a function of kinetic energy from thermal to 40 eV, and three endothermic product channels are observed. The dominant SiF+ + SiF3 channel is only slightly endothermic, while the ...Silicon fluoride; Ion-molecule reactions; Kinetic energy; Threshold behavior; Endothermic reactions1988
31 Francis, LeslieEvanescence of living willsOrdinary wills dispose of property after death. Living wills direct medical treatment at the end of life, before death has come but when competence is lost. The analogy explicit in naming living wills after ordinary wills emphasizes that both speak after their maker no longer can express voice, abou...Power of attorney; Competence; Autonomy1988
32 Seger, JonEvolution of individuality by Leo W. BussMetazoans seldom reproduce vegetatively; they often die of cancer; and they almost always sequester their germ lines. Plants often reproduce vegetatively, seldom die of cancer, and almost never sequester a germ line. Buss argues that these and many other patterns can all be understood in a unified w...Cell lines; Hierarchy; Biology1988
33 Gu, JunFast structured design of VLSI circuitsWe believe that a structured, user-friendly, cost-effective tool for rapid implementation of VLSI circuits which encourages students to participate directly in research projects are the key components in digital integrated circuit (IC) education. In this paper, we introduce our VLSI education activ...VLSI circuits; Rapid implementation1988

35 Miller, Joel Steven; Epstein, Arthur J.Ferromagnetism in molecular materials: decamethylferrocenium tetracyanoethanide [DMeFc][TCNE] (invited)Ferromagnetism has only recently been observed in molecular materials. We present here a summary of the ferromagnetic phenomena observed in the molecular charge transfer salt, decamethylferrocenium tetracyanoethanide (DMeFc) (TCNE), and related compounds. A spontaneous magnetization is observed i...Magnetic; Magnetization1988
36 Miller, Joel StevenFormation of a zwitterionic donor-acceptor compound based on N,N,N',N'-tetramethly-p-phenylenediamine and 7,7,8,8-tetracyanoperfluoro-p-quinodimethaneThe reaction of the donor N,N,N',N'- tetramethyl-p-phenylenediamine (TMPD) with the acceptor 7,7,8,8-tetracyanoperfluoro-p-quinodimethane (TCNQF4) has led to the isolation of a novel type of zwitterionic donor-acceptor compound whose structure has been determined by X-ray crystallography.Ccrystals; Single bond1988
37 Bohs, Lynn A.Four new species of Cyphomandra (Solanaceae) from South AmericaFour new species in the Neotropical genus Cyphomandra are described and illustrated. Cyphomandra pilosa and C. foetida are found on the eastern slopes of the Andes from Colombia to Peru. Cyphomandra oblongifolia is a morphologically variable species of Suriname and the Amazon basin. Cyphomandra sib...Cyphomandra1988

39 Gondolo, PaoloGroups of galaxies in the local supercluster: some hypotheses on the evolutionary stageWe present a method capable of determining the evolutionary stage of bound, isolated systems of galaxies. In particular, we apply it to a sample of groups, belonging to the Local Supercluster, taken from the Geller and Huchra's (1983) catalogue. We find that most of them are still in the phase of c...Evolution of galaxy clusters1988

42 Gopalakrishnan, GaneshHOP: a process model for synchronous hardware semantics, and experiments in process compositionWe present a language "Hardware viewed as Objects and Processes" (HOP) for specifying the structure, behavior, and timing of hardware systems. HOP embodies a simple process model for lock-step synchronous processes. An absproc specification written in HOP describes the externally observable behavior...HOP; Synchronous hardware semantics1988
43 Gopalakrishnan, GaneshHOP: a process model for synchronous hardware systemsModules in HOP are black-boxes that are understood and used only in terms of their interface. The interface consists of d a t a ports, events, and a protocol specification that uses events and asserts/queries values to / from ports. Events are realized as different combinations of control wires or...HOP; Process models; Synchronous hardware systems1988
44 Gu, JunHow to search for millions of queensThe n-queens problem is a classical combinatorial problem in artificial intelligence (AI) area. Since its simplicity and regular structure, this problem has widely been chosen as a testbed to develop and benchmark new AI search problem-solving strategies in the AI community. Due to its inherent com...Combinatorial problems; n-queens; Search algorithms1988
45 Horch, Kenneth W.Identification of single units in multi-unit recordings from peripheral nervesWe are developing a computer-based method for identifying individual action potentials in multi-unit peripheral nerve recordings. Threshold level, sinusoidal stimuli are used to elicit phase-locked activity from single units. These action potentials are digitized, and a template is constructed usin...Peripheral nerve; Neural recordings; Cutaneous mechanoreceptors1988

49 Horch, Kenneth W.Intrafascicular electrodes for nerve stimulationWe have designed a new type of intrafascicular, implanted electrode for stimulating peripheral nerves to elicit muscle contraction. The electrode requires low current to stimulate the nerve fibers, provides a fine control of muscular force, and causes little or no tissue reaction. it is of potential...Intrafascicular electrodes; Peripheral nerve; Neural recordings1988
50 Flynn, John J.Legal reasoning, antitrust policy and the social "science" of economicsThere is an area some eight to ten miles off Astoria, Oregon, called "The Bar," where the fresh water of the Columbia River meets the salt water of the Pacific Ocean. It is a place of turbulent, shifting currents and choppy waters where moving sand bars trap even the most experienced sailors. Like ...1988
