76 Stringfellow, Gerald B.Long wavelength lattice dynamics for quaternary alloys: GaInPSb and AlGaAsSbPresents information on a study which investigated the long wavelength lattice dynamics of quaternary alloys. Theory of the random cell isodisplacement model; Secular equation developed; Results and discussion.Lattice dynamics; Quaternary alloys1992
77 Couldwell, William T.Malignant glioma-derived soluble factors regulate proliferation of normal adult human astrocytesMalignant gliomas are characteristically surrounded by marked gliosis. To assess whether glioma-derived products contribute to the proliferation of astrocytes, a feature of the gliosis response, we evaluated the influence of culture supernatants from malignant human glioma lines and tumor cyst fluid...Astrocyte; Glioma; Gliosis; Proliferation; Soluble factors1992
78 Warner, Homer R.Medical Informatics: Application of Computers to Medical ScienceBiomedical Informatics1992
79 Zachary, Joseph L.Metamusing on object persistenceThe need to "open up languages" has led to object-oriented programming languages with object-oriented implementations. By encapsulating the fundamental aspects of a language semantics within a set of default classes and giving t h e programmer t h e flexibility of deriving new versions of these base...Metamusing; Object persistence1992
80 Brown, Francis HaroldMethods of datingThe fossil record of primates begins in the latest Cretaceous period, so primate palaeontologists are interested in techniques of dating applicable over the past 70 million years. Fossil bones themselves are rarely datable with any precision, and these are mainly of late Pleistocene or Holocene age....1992
81 Normann, Richard A.; Horch, Kenneth W.; Cha, KichulMobility performance with a pixelized vision systemA visual prosthesis, based on electrical stimulation of the visual cortex, has been suggested as a means for partially restoring functional vision in the blind. The prosthesis would create a pixelized visual sense consisting of punctate spots of light (phosphenes). The present study investigated the...Visual Prosthesis; Mobility; Phosphene Simulator1992
82 Florsheim, Paul W.Mourning the loss of "self as father": a longitudinal study of fatherhood among the druzeIT is within the context of the parent-child relationship - through the processes of attachment, loss, separation and individuation - that we grow and develop interpersonally and intrapsychically (Bowlby 1969, 1980; Mahler et al. 1975; Pollock, 1989). Most developmentalists agree that changes in th...1992
83 Mathews, V. JohnMultiplication free vector quantization using the L 1 distortion measure and its variantsVector quantization is a very powerful technique for data compression and consequently, it has attracted a lot for attention lately. One major drawback associated with this approach is its extreme computational complexity. This paper fist considers vector quantization that uses the L1 distortion mea...1992
84 Gondolo, PaoloNeutralinos as dark matter in the minimal supergravity modelA new approach to the phenomenological study of the minimal supergravity model is presented in which the model is effectively parametrized in terms of five low energy observables. Radiative corrections due to large Yukawa couplings and particle-sparticle mass splitting are included into the analysis...Neutralinos1992
85 Fogel, Alan DaleNoninnatist alternatives to the negative evidence hypothesisIn this commentary we consider three issues. First, we suggest that Crain's definition of innateness is not biologically plausible. Second, we show how the criteria he uses as hallmarks of innateness can have alternative explanations. Finally, we reinterpret his research findings on grounds that do ...1992
86 Richardson, William F.; Brunvand, Erik L.The NSR processor prototypeThe NSR (Non-Synchronous RISC) processor is a general purpose processor structured as a collection of self-timed units that operate concurrently and communicate over bundled data channels in the style of micropipelines. These units correspond to standard synchronous pipeline stages such as Instructi...Self-timed Systems; Asynchronous systems; Micropipelines; FPGAs; RISC processor; NSR1992

88 Caserta, Michael; Lund, Dale A.Older bereaved spouses' participation in self-help groupsThis study reports on bereaved spouses' assessments of their participation in twenty-six self-help groups which consisted of eight weekly meetings (short-term; N = 82) or ten monthly meetings in addition to the weekly ones (long-term; N = 52). Regardless of the duration of the groups whether they w...Older bereaved spouses1992
89 Orr, Douglas B.OMOS - An object server for program executionThe benefits of object-oriented programming are well known, but popular operating systems provide very few object-oriented features to users, and few are implemented using object-oriented techniques themselves. In this paper we discuss a mechanism for applying object-oriented programming concepts to...OMOS; Object server1992

91 Miller, Joel Steven; Epstein, Arthur J.Organic and molecular ferromagnetsUnlike common ferromagnets such as iron, nickel, cobalt or even cobalt-samarium and Nb-Fe-B, it is extremely rare for a discrete molecule, especially an organic or polymeric material, to have cooperative magnetic interactions. Since the mid-1980s a few such materials have been prepared which demon...Magnetic; Magnetization; Temperature1992
92 Flynn, John J.Orphan Drug Act: an unconstitutional exercise of the patent powerIn 1983, Congress adopted the Orphan Drug Act (the "Act") pursuant to its power to regulate interstate and foreign commerce to stimulate research and development of drugs useful in treating relatively rare diseases.1 The cost of drug research and complying with the complex requirements for securing ...Health Care; Drugs; Medicine; Medical treatment1992
93 Lindstrom, Gary E.Our LIPS are sealed: interfacing logic and functional programming systemsWe report on a technique for interfacing an untyped logic language to a statically poly morphically typed functional language Our key insight is that polymorphic types can be interpreted as "need to know" specifications on function arguments. This leads to a criterion for liberally yet safely invoki...LIPS; Logic language; Functional language1992
94 Silverman, Randall H.Pamphlet binders and their use in research librariesBy definition, research libraries have a commitment to preserving pamphlets as well as all print and non-print media they collect. A discussion of the preservation requirements for pamphlets is useful for their survival, and pamphlet binders are an important tool in preparing these often ephemeral ...Pamphlets; Preservation; Binders1992
95 O'Rourke, Dennis H.Patterns of genetic variation in native AmericaAllele frequencies from seven polymorphic red cell antigen loci (ABO, Rh, MN, S, P, Duffy, and Diego) were examined in 144 Native American populations. Mean genetic distances (Nei's D) and the fixation index FST are approximately equal for the North and South American samples but are reduced in the...Gene frequencies; Amerinds; Genetic Distance1992

97 Berg, Cynthia A.Perspectives for viewing intellectual development throughout the life courseWhat has one voice and is four-footed, two-footed, and three-footed? The task of characterizing intellectual development throughout the life course can be likened to the situation that faced the Thebans as they tried to solve this riddle of the Sphinx. Oedipus gave the correct answer to this riddle...1992
98 Ehleringer, James R.Plant adaptation in the Great Basin and Colorado PlateauAdaptive features of plants of the Great Basin are reviewed. The combination of cold winters and an arid to semiarid precipitation regime results in the distinguishing features of the vegetation in the Great Basin and Colorado Plateau. The primary effects of these climatic features arise from how t...Plant adaptation; Great Basin; Colorado Plateau; Cold deserts1992

100 Morse, Michael DavidPredissociation lifetimes of vibrational levels of the excited ? B? (Ka=O) electronic states of Cd ? H? and Cd ? D? complexesThe experimental rates of predissociation of vibrational levels of the ?B? (K'a-O) excited states of the Cd ? HZ and Cd ? D2 complexes are shown to be consistent with both semiclassical and quantum-mechanical pseudodiatomic theoretical treatments of the process. The ?B? pseudodiatomic potential was ...1992
