76 Gopalakrishnan, GaneshSome recent asynchronous system design methodologiesWe present an in-depth study of some techniques for asynchronous system design, analysis, and verification. After defining basic terminology, we take one simple example - a four-phase t o two-phase converter - and present its design using (a) classical flow-tables; (b) Signal Transition Graphs of [...Asynchronous system design1990
77 Miller, Jan D.Spectroscopic analysis of passivation reactions for carbonaceous matter from carlin trend oresAbstract. Three different refractory carbonaceous gold ores from the Carlin operation in northeastern Nevada were investigated to characterize the effect of passivation treatments on the nature of the carbonaceous material. The carbonaceous material was chemically isolated from the ores and pass...Gold; Chlorine; Cyanidation1990
78 Morse, Michael DavidSpectroscopy and electronic structure of jet-cooled Al?Resonant two-photon ionization spectroscopy has been used to study the jet-cooled Al? molecule. The ground state has been conclusively demonstrated to be of 3IIu symmetry, deriving from the ???rr?u electronic configuration. High resolution studies have established the bond length of the X?IIu state ...1990
79 Morse, Michael DavidSpectroscopy and electronic structure of jet-cooled NiPd and PdPtResonant two-photon ionization spectroscopy of jet-cooled NiPd and PdPt has revealed a dense vibronic spectrum for NiPd and a much more sparse spectrum for PdPt. Four vibrational progressions have been identified for NiPd, and three have been located for PdPt. High resolution investigations of NiPd...1990
80 Mathews, V. JohnStochastic gradient adaptive filters with gradient adaptive step sizesThis paper presents two adaptive step-size gradient adaptive filters. The step sizes are changed using a gradient descent algorithm designed to minimize the squared estimation error. The first algorithm uses the same step-size sequence for all the filter coefficients whereas the second algorithm use...1990
81 White, Nicholas P.Stoic valuesRM: Copyright © 1990, The Monist: An International Journal of General Philosophical Inquiry, Peru, Illinois, U.S.A., 61354, reproduced by permission. Discusses the values of Stoicism which say noting concrete about how a virtuous person should go about making choices and examines the Stoics im...Virtuous; Indifferent; Worth1990
82 Vardeny, Zeev ValentineStudies of picosecond carrier dynamics in polysilane alloys: evidence for geminate recombination in small hydrogenated amorphous silicon clustersThe ultrafast photocarrier dynamics in polysilane alloys amorphous (SiH2)n' has been studied using the picosecond photoinduced absorption (PA) technique. For excitation below the optical gap, the PA response decays exponentially and is faster at low temperatures. This is interpreted in terms of e-h ...Picosecond carrier dynamics; Polysilane alloys; Geminate recombination; a-Si:H; Amorphous silicon; Ultrafast relaxation; Photoexcited carriers1990
83 Potts, Wayne K.Surprisingly uneven distribution of the T cell receptor Vβ repertoire in wild miceHeterodimeric TCRa/Bs are made up of combinations of V D, J, and C elements. The majority of laboratory inbred mouse strains are of the VBh haplotype and have at least 20 VB genes from which to construct TCRs (1, 2); however, a number of strains have been reported to have deletions of large portion...1990

85 Bohs, Lynn A.Systematics of Solanum section Allophyllum (Solanaceae)Three species of Solarium are included in a new section, Solarium sect. Allophyllum. Two of the species, S. allophyllum and S. mapiriense, have been previously known; the third, S. morellifolium Bohs, is described as new. The combination of characters exhibited by members of this section, such as un...Solanum section Allophyllum; Solanum allophyllum; Solanum morellifolium; Solanum mapiriense1990

87 Mathews, V. JohnTracking analysis of the sign algorithm in nonstationary environmentsAbstract-This paper presents a tracking analysis of the adaptive filters equipped with the sign algorithm and operating in nonstationary environments. Under the assumption that the nonstationarity can be modeled using a random disturbance, it is shown that the long-term time average of the mean-abso...1990

89 Vardeny, Zeev ValentineUltrafast electronic and acoustic effects in conducting polymersThe polarized picosecond pump and probe technique with 50 fsec resolution has been used to generate and detect electronic excitations and propagation of ultrasonic phonons in thin films of oriented and unoriented polyacetylene and polythiophene. We found that the photoexcitations are instantaneou...Ultrafast electronic effects; Ultrafast acoustic effects; Polarized picosecond pump; Pump and probe technique; Ultrasonic phonons1990
90 Couldwell, William T.Utilization of unilateral and bilateral stereotactically placed adrenomedullary-striatal autografts in Parkinsonian humans: rationale, techniques, and observationsA limited clinical pilot study involving an amalgam of specialized disciplines including neurology, neuropharmacology, neuropsychology, neurosurgery, neuroanesthesia, neuroradiology, surgical pathology, neuropathology, and urological surgery was organized to clarify issues related to patient selecti...Adrenal medullary graft; Autograft; Brain graft; Neural transplantation; Parkinsonism; Stereotaxy1990
91 Flynn, John J.Which past is prolog? the future of private antitrust enforcementFor the past four decades, and despite doubts voiced 100 years ago by the principal draftsmen of the Sherman Act,' the primary enforcement of the federal antitrust laws has occurred through private litigation.21990
92 Henderson, Thomas C.Zo: A framework for autonomous agent behavior specification and analysisWe describe a framework for the specification and analysis of autonomous agents1 . In general, such agents require several levels of behavioral specifications, including: low-level reflex actions, mid-level controllers to deal with the physical aspects of the world, and highlevel representations for...Z-Infinity; Autonomous agents; Behavior1990
