151 Silverman, Randall H.First word in lasting impressionsThe creaking lever-action of a Columbian letterpress printing damped, handmade paper with cast metal type is an anomaly in the modern age. What now can be achieved within minutes on an offset press requires hours of meticulous setting, locking up, inking, and proofing to print on a Columbian powered...Columbian letterpress; Clymer; Red Butte Press1993
152 Awate, Suyash P.; Whitaker, Ross T.Higher-order image statistics for unsupervised, information-theoretic, adaptive, image filteringThe restoration of images is an important and widely studied problem in computer vision and image processing. Various image filtering strategies have been effective, but invariably make strong assumptions about the properties of the signal and/or degradation. Therefore, these methods typically la...Image filtering; Image restoration2005-04-15
153 Gesteland, Raymond F.; Atkins, John F.Influence of the stacking potential of the base 3' of tandem shift codons on -1 ribosomal frameshifting used for gene expressionTranslating ribosomes can shift reading frame at specific sites with high efficiency for gene expression purposes. The most common type of shift to the 1 frame involves a tandem realignment of two anticodons from pairing with mRNA sequence of the form X XXY YYZ to XXX YYY Z where the spaces indicate...1 frameshifting; 39 context effect; Codon anticodon interaction; Escherichia coli ; Recoding; tRNALys; XXXY YYZ frameshift motifs2002

155 Mattis, Daniel C.Limit model of CuO2 planes: exact resultsWe solve the simplest tight-binding model of electrons in a CuO2 plane with Coulomb repulsion only on the copper ions, by a limiting procedure which retains all contributions 0(t2/U) while projecting out the higher order terms. In addition to the ground state energy we identify a variety of quasipar...Electrons; Particle-hole1995
156 Liu, FengPressure-induced transition in magnetoresistance of single-walled carbon nanotubesWe applied hydrostatic pressure (up to 10 GPa) to single-walled carbon nanotube bundles at low temperature (down to 2 K) to measure their magnetoresistance (MR) in a field up to 12 T. We found a pressure-induced transition in MR from positive to negative in the high-field regime. The onset of the tr...Single-walled carbon nanotubes; Pressure-induced2006-07
157 Mitchell, Joyce A.Retrieval from full-text medical literature: the dream & the realityWhile the retrieval of the full-text of a document might seem to end all the hassle of using traditional retrieval systems, the results of the MEDLINE/Full-Text Project indicate that retrieval from the current full-text databases of biomedical journal literature does not match the dream. During the ...1991-01-01
158 Mattis, Daniel C.Second-order phase transition in a model random alloyWe investigate the existence and stability of long-range order in a simple model of a binary alloy. We find that for electron concentrations in the vicinity of one per atom, in bipartite lattices, long-range order of the atoms exists at low temperatures, and we find that the system undergoes a secon...Phase transition; Random alloys; Quasiparticles; Density of state1973-03

173 Balasubramonian, RajeevStaged reads: mitigating the impact of DRAM writes on DRAM readsMain memory latencies have always been a concern for system performance. Given that reads are on the criti- cal path for CPU progress, reads must be prioritized over writes. However, writes must be eventually processed and they often delay pending reads. In fact, a single channel in the main memory ...2012-01-01
174 Hansen, Charles D.Parallel volume rendering using binary-swap compositingExisting volume rendering methods, though capable of very effective visualizations, are computationally intensive and therefore fail to achieve interactive rendering rates for large data sets.
