1 Goldberg, Robert A.Zion in Utah: the Clarion colony and Jewish agrarianismThe history of the Jewish agricultural colony at Clarion, Utah, presented by Robert A. Goldberg is somewhat special, for western Jewish history has been notably small town and urban. In painstakingly reconstructing the story of those who organized, settled, and finally failed at Clarion, Goldberg ...1991
2 Horch, Kenneth W.Information extraction from peripheral nervesThis work is directed toward providing better rehabilitation for people suffering from somatosensory loss and paralysis due to spinal cord injury, head trauma, or stroke. The goal of this project is to demonstrate that information suitable for controlling prosthetic devices, modulating functional el...Peripheral nerve; Neural recordings; Intrafascicular electrodes1991

4 Horch, Kenneth W.Information contrained in sensory nerve recordings made with intrafascicular electrodesMultiunit recordings were made in anesthetized cats with chronically implanted intrafascicular electrodes over a period of six months. Neural signals recorded with these electrodes consisted of activity in sensory fibers innervating a variety of cutaneous mechanoreceptors. Mechanical stimuli wer...Intrafascicular electrodes; Functional electrical stimulation (FES); Closed-loop control1991
5 Starkey, MikeTransforming disfigured and disoriented areas into routable switchboxesRouting an entire circuit requires partitioning the circuit (routing area) into smaller, localized routing areas. Using non-rectangular, rotated switchbox shapes (and therefore non-manhattan routing layout) has the potential to simplify the partitioning of the circuit into routable areas and to use ...Disfigured areas; Disoriented areas; routable switchboxes1991
6 Vardeny, Zeev Valentine; Symko, Orest GeorgeQuasiparticle relaxation in high-Tc superconductorRecent measurements by Eesley et al. [1] of transient reflectivity in superconducting Tl2Ba2Ca2Cu30io were interpreted as evidence for order-parameter relaxation in the vicinity of Tc, which was analyzed in terms of BCS weak coupling for ?(r)/?(0). In this Comment we question this interpretation ...Quasiparticle relaxation1991

[1] of transient reflectivity in superconducting Tl2Ba2Ca2Cu30io were interpreted as evidence for order-parameter relaxation in the vicinity of Tc, which was analyzed in terms of BCS weak coupling for A(r)/A(0). In this Comment we question this interpretation ...Quasiparticle relaxation; High-tc1991
8 McCullough, John M.Relatedness and kin-structured migration in a founding population: Plymouth colony, 1620-1633To test the common assumption of no genetic relationship in a founding population, we calculated average relatedness (r) for the emigrants to Plymouth Colony from Europe on seven voyages from 1620 to 1633. Of 355 individuals, 255 could be individually identified and 4 generations of genealogic depth...1991

10 Cotter, Neil E.Prejudicial search and backpropThis paper introduces the combination of backward error propagation and prejudicial search. Prejudicial search is a method, which like simulated annealing, guarantees convergence to a global minimum as time approaches infinity. Unlike simulated annealing, its application is more flexible because it ...1991
11 Horch, Kenneth W.Muscle recruitment with intrafascicular electrodesWe have studied muscle recruitment with Tefloninsulated, 25 pm diameter, Pt-Ir intrafasicular electrodes implanted in nerves innervating the gastrocnemius and soleus muscles of cats. The purpose of this study was to measure the performance of these bipolar electrodes, which had been designed to...Functional neuromuscular stimulation (FNS); Intrafascicular electrode1991
12 Brown, Francis HaroldCorrelation of tephra layers from the Western Rift Valley (Uganda) to the Turkana Basin (Ethiopia/Kenya) and the Gulf of AdenFour volcanic ashes have been mapped in Albertine Group strata (Warwire, Kaiso Village and Nyabusosi Formations) Western Rift Valley, Uganda. Three of these tuffs have geochemical fingerprints similar to tuffs in the Turkana Basin (Ethiopia, Kenya), in Afar (Ethiopia) and the Gulf of Aden, permitti...1991
13 Normann, Richard A.; Campbell, Patrick K.; Jones, Kelly E.; Huber, Robert J.; Horch, Kenneth W.Silicon-based, three-dimensional neural interface: manufacturing processes for an intracortical electrode arrayA method has been developed for the manufacture of a "three-dimensional" electrode array geometry for chronic intracortical stimulation. This silicon based array consists of a 4.2 x 4.2 x 0.12 mm thick monocrystalline substrate, from which project 100 conductive, silicon needles sharpened to facilit...Electric Stimulation; Electrodes, Implanted; Sensory Cortex; Intracortical Electrode Array1991
14 Starkey, MikeA lisp-based occam interpreterThe OCCAM programming language is an implementation of Communicating Sequential Processes and is used in a number of different areas. These areas usually require explicitly describing small-grain paralleslism. OCCAM programs formed by such descriptions can be tested for correctness by executing the...Lisp-based; Occam interpreter1991
15 Starkey, MikeSwitchbox routing by pattern matchingMany good algorithms have been designed that provide good solutions to the wire routing problem in VLSI. Unfortunately, many of these algorithms only consider a small subset of different parameters such as number of layers, routability of layers and technology. We believe that these algorithms can b...Switchbox routing; pattern matching; wire routing problem; VLSI1991
16 Rogers, Alan R.Doubts about isonymyThe method of isonymy, developed by Crow and Mange for estimating inbreeding from surname frequencies, requires an assumption that has not been appreciated: It is necessary to assume that all males in some ancestral generation, the founding stock, had unique surnames. Because this assumption is sel...1991
17 Gopalakrishnan, GaneshEfficient symbolic simulation based verification using the parametric form of boolean expressions (rev.)We present several new techniques to make symbolic simulation based verification efficient. These techniques hinge on the use of the parametric form of a boolean expression (e.g. the parametric form for the boolean expression XQ V -<xi is the equivalent expression 3a b . (XQ = a V 6) A (xi = b), whe...Symbolic simulation; Verification1991

19 Mathews, V. JohnPerformance analysis of adaptive filters equipped with the dual sign algorithmAdaptive filters equipped with the sign algorithm are attractive in many applications because of their computational simplicity. Unfortunately, their slow speed of convergence is a major limitation. The dual sign algorithm (DSA) is a means by which the convergence speed can be increased without over...1991

21 Miller, Jan D.Search for adsorbed gold cyanide on carbon surfacesThe mechanism of adsorption of gold from alkaline cyanide solutions by carbon has been the subject of much research over the past decade. In this paper, the nature of the gold cyanide adsorption phenomenon is investigated, particularly with respect to carbon substrates and associated surface adsorpt...Gold cyanide; spectrometers; X-ray photoelectron spectroscopy1991
22 Henderson, Thomas C.Parallel path consistencyFiltering algorithms are well accepted as a means of speeding up the solution of the consistent labeling problem (CLP). Despite the fact that path consistency does a better job of filtering than arc consistency, AC is still the preferred technique because it has a much lower time complexity. We ar...Filtering algorithms; Parallel paths; Consistency; Consistent labeling problem; CLP1991
23 Mathews, V. JohnParameter estimation for a bilinear time series modelABSTRACT This paper presents a direct approach to the estimation of the parameters associated with a bilinear time series model. The approach depends critically on the expressions for certain higher-order statistics of the signals that satisfy the bilinear model. These expressions are linear in mo...1991

25 Mathews, V. JohnOutput-error adaptive bilinear filtersThis paper presents an overview of several gradient type recursive algorithms for adaptive nonlinear filters equipped with bilinear system models.
