76 Back, Godmar V.Java operating systems: design and implementationLanguage-based extensible systems such as Java use type safety to provide memory safety in a single address space. Memory safety alone, however, is not sufficient to protect different applications from each other. such systems must support a process model that enables the control and management of c...Java operating systems; Language-based systems1998

79 Golden, Kenneth M.Laboratory measurements of sea ice: connections to microwave remote sensingThe connections between laboratory measurements and remote-sensing observations of sea ice are explored. The focus of this paper is on thin ice, which is more easily simulated in a laboratory environment. We summarize results of C-band scatterometer measurements and discuss how they may help in the ...Electromagnetic; Radar; Backscatter1998
80 Chapman, David S.; Allis, Richard GeorgeLate Neogene exhumation patterns in Taranaki Basin (New Zealand): evidence from offset porosity-depth trendsTaranaki Basin, New Zealand, is located adjacent to the Australian-Pacific Plate boundary where the tectonic regime changes from dominantly subduction-related to the north to transpression-related along the Alpine Fault to the south. During the Neogene, burial and exhumation varied extensively, in ...Neogene; Uplift; Exhumation; Taranaki Basin; New Zealand1998
81 Fu, YingbinMechanism of reductive activation of potato tuber ADP-glucose pyrophosphorylase.The potato tuber (Solanum tuberosum L.) ADP-glucose pyrophosphorylase activity is activated by a incubation with ADP-glucose and dithiothreitol or by ATP, glucose- 1-phosphate, Ca2+, and dithiothreitol. The activation was accompanied by the appearance of new sulfhydryl groups as determined with 5, 5...Glucosephosphates; Enzyme Activation; Adenosine Triphosphate1998
82 Ameel, Timothy AMicrochannel fluid behavior using micropolar fluid theoryIn this paper, we describe microchannel fluid behavior using a numerical model based on micropolar fluid theory and experimentally verify the model using micromachined channels. The micropolar fluid theory augments the laws of classical continuum mechanics by incorporating the effects of fluid ...1998
83 Beckerle, Mary C.Mutations in Drosophila enabled and rescue by human vasodilator-stimulated phosphoprotein (VASP) indicate important functional roles for Ena/VASP homology domain 1 (EVH1) and EVH2 domainsDrosophila Enabled (Ena) was initially identified as a dominant genetic suppressor of mutations in the Abelson tyrosine kinase and, more recently, as a member of the Ena/human vasodilator-stimulated phosphoprotein (VASP) family of proteins. We have used genetic, biochemical, and cell biological appr...Drosophila Ena; VASP1998
84 Symons, John DavidNa-H exchange inhibition with Cariporide limits functional impairment caused by repetitive ischemiaIntracellular calcium ([Ca]i) overload on reperfusion may be one of the mechanisms responsible for ischemia-induced regional myocardial dysfunction. Because inhibiting the Na-H exchanger (NHE) limits intracellular sodium ([Na]i) and subsequent [Ca]i accumulation, we hypothesized that NHE inhibition ...Reperfusion; intracellular calcium; conscious pigs1998
85 Davidson, Diane W.Nonnative brome grasses in the new national monumentIncluded within the boundaries of the Grand-Staircase Escalante National Monument are a number of noxious weeds for which the BLM mandates control. In addition to listed weeds are nonnative brome grasses [Bromus tectorum and Bromus rubens), which can potentially convert native ecosystems to biologic...Noxious weeds, Cheatgrass,1998
86 Goller, FranzOntogeny of song lateralization in juvenile northern cardinalsIn adult northern cardinals (Cardinatte cardinalis), the left and right sides of the syrinx cover different vocal registers such (hat fundamental frequencies below about 3.5 or 4 kHz are produced only by the left syrinx and higher frequencies are produced primarily by the light syrinx.Motor control; FM sweep; Subsong1998
87 Mathews, V. JohnParallel-cascade realizations and approximations of truncated volterra systemsAbstract- This correspondence introduces parallel-cascade realizations of truncated Volterra systems with an arbitrary but finite order of nonlinearity. Parallel-cascade realizations implement higher order Volterra systems using parallel and multiplicative combinations of lower order Volterra system...1998
88 Gerton, JordanPhase-contrast imaging of atomic superfluid state in degenerate gas of 6Li atomsThe recent experimental realizations of Bose-Einstein condensation in trapped ultracold atomic gases composed of bosonic alkali atoms has generated a broad interest in studying different properties of these degenerate atomic Bose systems. Although the degenerate atomic gas composed of fermionic atom...1998
89 Christensen, Douglas A.Plasma-etched polymer waveguides for intrachip optical interconnectsOptical intrachip communication offers the potential advantages of high speed and lack of electrical interference. We report on progress made on an interconnect design using GaAs LEDs, polymer waveguides, and photodiodes in a silicon substrate. The polymer waveguides are fabricated in polyimide or p...Polymer waveguides; Intrachip interconnects; LEDs1998
90 Vardeny, Zeev ValentinePlastic microring lasers on fibers and wiresPhotopumped, pulsed, narrow line laser emission is demonstrated using cylindrical microcavities formed by p-conjugated polymer thin films wrapped around thin glass optical fibers and metal wires with various diameters D. A variety of cavity-dependent resonant laser mode structures were observed, whi...Microring lasers; pi-conjugated polymers; pi-conjugated polymer thin films; Microcavities1998
91 Couldwell, William T.Posterolateral approach for decompression with anterior and posterior fusion: a less invasive surgical technique for stabilization of the thoracic spineThe goals of surgery in unstable thoracic fractures or tumors involving the thoracic spine are neural decompression, correction of deformity, and stabilization. Several different approaches can be used to achieve these goals. The anterior, combined anterior and posterior, and more recently thoraco...Decompression; Thoracic spine; Posterolateral approach1998
92 Gesteland, Raymond F.; Ivanov, Ivaylo P.; Atkins, John F.Programmed frameshifting in the synthesis of mammalian antizyme is +1 in mammals, predominantly +1 in fission yeast but "2 in budding yeastThe coding sequence for mammalian ornithine decarboxylase antizyme is in two different partially overlapping reading frames with no independent ribosome entry to the second ORF. Immediately before the stop codon of the first ORF, a proportion of ribosomes undergo a quadruplet translocation event t...Antizyme; Frameshifting; Ornithine decarboxylase antizyme; Recoding; S. pombe1998
93 Saam, BrianProtection circuitry for high-power diode laser arraysA comprehensive protection scheme is presented for use with high-power (;500 W dc input! diode laser arrays. The circuitry requires no separate power, using instead the voltage from the laser's power supply. Overcurrent and overvoltage silicon controlled rectifier crowbars are the primary protection...Protection circuitry; High-power diode laser arrays1998
94 McDaniel, SusanPublic policy, demographic aging and familiesVoodoo demographics, a term coined by American economist James Schulz in the late 1980s, describes the belief that aging populations pose threats to life and society as we know it, particularly to social safety nets, education, public health care, as well as challenges to families. Surprisingly, the...1998
