328 Mathews, V. JohnEfficient FIR adaptive filter using DPCM and the sign algorithmThis correspondence introduces an adaptive filter structure that requires zero multiplications for its implementation.

332 Chapman, David S.Exhumation of the central Wasatch Mountains, Utah: 1, Patterns and timing of exhumation deduced from low-temperature thermochronology dataThe Wasatch Mountains are often cited as an example of normal fault growth and footwall flexure. They represent a tilted footwall at the edge of the Basin and Range extensional province, a major rift basin. Thus understanding the detailed spatial and elevation changes in coupled thermochronometer da...Uplift; Exhumation; Wasatch Fault; Wasatch Mountains; Utah; Helium dating; Fission track; Tectonophysics; Extensional tectonics; Geothermal observations2002

334 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
335 Dailey, Andrew T.Surgical treatment of occipitocervical instabilityOBJECTIVE: Instability of the occipitocervical junction can be a challenging surgical problem because of the unique anatomic and biomechanical characteristics of this region. We review the causes of instability and the development of surgical techniques to stabilize the occipitocervical junction. ...Occipitocervical instability2008
336 Forster, Richard R.Prevalence of pure versus mixed snow cover pixels across spatial resolutions in alpine environmentsRemote sensing of snow-covered area (SCA) can be binary (indicating the presence/absence of snow cover at each pixel) or fractional (indicating the fraction of each pixel covered by snow). Fractional SCA mapping provides more information than binary SCA, but is more difficult to implement and may no...2014-01-01
337 Riloff, Ellen M.Unified model of phrasal and sentential evidence for information extractionInformation Extraction (IE) systems that extract role fillers for events typically look at the local context surrounding a phrase when deciding whether to extract it. Often, however, role fillers occur in clauses that are not directly linked to an event word. We present a new model for event extract...Information extraction; Phrasal evidence; Sentential evidence; Role fillers; Event extraction; Sentential event recognizer; Plausible roll-filler recognizer2009
338 Broughton, JohnPristine benchmarks and indigenous conservation? Implications from California zooarchaeologyThe superabundance of tame wildlife during the early historic period in California astonished European explorers. And the historic accounts of incredible animal densities, most notably artiodactyls, have influenced a long-held perception that California Indians lived in harmony with nature. However,...2004-01-01
339 Liu, FengInfluence of quantum size effects on Pb island growth and diffusion barrier oscillationsQuantum size effects are successfully exploited in manipulating the growth of (111) oriented Pb islands on Si(111) substrate with a scanning tunneling microscope. The growth dynamics and morphology displayed can be well controlled through the quantum size effects defined by the island thicknesses ...Quantum size effects; QSE; Pb island; Diffusion barrier oscillations2006-08
340 Wu, Yong-ShiNear-horizon Virasoro symmetry and the entropy of de Sitter space in any dimensionDe Sitter spacetime is known to have a cosmological horizon that enjoys thermodynamic-like properties similar to those of a black hole horizon. In this note we show that a universal argument can be given for the entropy of de Sitter spacetime in arbitrary dimensions, by generalizing a recent near ho...1999-05
341 Gopalakrishnan, GaneshPredicate abstraction for MurphiPredicate abstraction is a technique used to prove properties in a finite or infinite state system. It employs decision procedures to abstract a concrete state system into a finite state abstraction system, which will then be model checked and refined. In this paper, we present an approach for im...Predicate abstraction; Murphi2006
342 Coley, Phyllis D.Vesicular-arbuscular mycorrhizae in two tropical monodominant treesMycorrhizae, symbioses between plant roots and fungi, are found in virtually all terrestrial plant ecosystems.

349 Adler, Frederick R.How virulent should a parasite be to its vector?Vector-borne parasites are commonly predicted to be less virulent to the vector than to the definitive host as the parasite gains little by harming its main route of transmission. Here we assess the empirical evidence from systems in which insects are vectors for vertebrate, plant, and invertebrate ...Parasite virulence; Hosts; Vector-borne parasite2003
350 Schmidt, Meic H.Frameless stereotactic image-guided C1-C2 transarticular screw fixation for atlantoaxial instability: review of 20 patientsAtlantoaxial instability can result from trauma, rheumatoid arthritis, congenital malformation, or tumor invasion. The goal of treatment is stabilization of the C1-C2 complex to prevent neurologic and neurovascular compromise.
