126 Flowers, SevilleFerns of UtahThe distribution of many species of our ferns is not well known in Utah. Collectors have centered their work around certain localities and many blank spots appear on the distributional map. One might presume certain species to be present in some of these unexplored areas but specimens are still to b...1944-11-15
127 Boehme, ChristophTheory of the time-domain measurement of spin-dependent recombination with pulsed electrically detected magnetic resonanceThe theoretical foundations of the time domain measurement of spin-dependent charge carrier recombination by means of pulsed electrically detected magnetic resonance (EDMR) are outlined. Pulsed EDMR is based on the transient measurement of electrical currents in semiconductors after a coherent manip...Spin-dependent recombination2003-12
128 Jorgensen, ErikAxons break in animals lacking B-spectrinAxons and dendrites can withstand acute mechanical strain despite their small diameter. In this study, we demonstrate that β-spectrin is required for the physical integrity of neuronal processes in the nematode Caenorhabditis elegans. Axons in β-spectrin mutants spontaneously break.2007

130 Beckerle, Mary C.Comparison of three members of the cysteine-rich protein family reveals functional conservation and divergent patterns of gene expressionMembers of the cysteine-rich protein (CRP) family are evolutionarily conserved proteins that have been implicated in the processes of cell proliferation and differentiation. In particular, one CRP family member has been shown to be an essential regulator of cardiac and skeletal muscle development.LIM domains; Chicken fibroblasts; Zyxin; Actinin; Protein expression; Cysteine-rich proteins1997
131 Capecchi, Mario R.Role of the N-terminal catalytic domain of angiotensin-converting enzyme investigated by targeted inactivation in miceAngiotensin-converting enzyme (ACE) produces the vasoconstrictor angiotensin II. The ACE protein is composed of two homologous domains, each binding zinc and each independently catalytic. To assess the physiologic significance of the two ACE catalytic domains, we used gene targeting in mice to int...2004-02-13
132 Bhanu, BirShape matching of two-dimensional objectsIn this paper we present results in the areas of shape matching of nonoccluded and occluded two-dimensional objects. Shape matching is viewed as a "segment matching" problem. Unlike the previous work, the technique is based on a stochastic labeling procedure which explicitly maximizes a criterion ...Shape matching; Two-dimensional objects; Segment matching1984
133 McDaniel, SusanSeniors and portrayals of intra-generational and inter-generational inequality in the Globe and MailIn this article, we examine how seniors are portrayed in the Globe and Mail. Thirty articles published in 2004 were selected and thematically analysed. Seniors were discussed in six different contexts, including family, work/retirement, community networks, scientific studies of population, social a...2006
134 Lindstrom, Gary E.The design of object-oriented meta-architectures for programming languagesThis paper is a survey of the design of four object-oriented meta-level architectures for programming languages. We present overviews and compare the salient features of the meta-architectures of Smalltalk, Common Lisp Object System (CLOS), a Scheme Compiler, and Etyma, our framework for modular sy...Meta-level architectures; Design1994
135 Kieda, David B.Toward a revival of stellar intensity interferometryBuilding on technological developments over the last 35 years, intensity interferometry now appears a feasible option by which to achieve diffraction-limited imaging over a square-kilometer synthetic aperture. Upcoming Atmospheric Cherenkov Telescope projects will consist of up to 100 telescopes, ...Intensity interferometry; Air Cherenkov Telescope2008

137 Silverman, RandyBernard C. Middleton, MBE (1924-2019):Bernard Chester Middleton was born in London in 1924 to Doris Hilda Webster, a secretary to a well-known barrister, and Regent Marcus Geoffrey Middleton, a talented bookbinder. At the age of thirteen in 1938, Bernard earned a trade scholarship to attend the Central School of Arts and Crafts in Londo...1995
138 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
139 Stevens, KennethLazy transition systems and asynchronous circuit synthesis with relative timing assumptionsThis paper presents a design flow for timed asynchronous circuits. It introduces lazy transitions systems as a new computational model to represent the timing information required for synthesis. The notion of laziness explicitly distinguishes between the enabling and the firing of an event in a tr...2002
140 Beckerle, Mary C.Characterization of the interaction between zyxin and members of the Ena/Vasodilator-stimulated Phosphoprotein family of proteinsZyxin contains a proline-rich N-terminal domain that is similar to the C-terminal domain in the ActA protein of the bacteria, Listeria monocytogenes. We screened the entire amino acid sequence of human zyxin for Menainteracting peptides and found that, as with ActA, proline-rich sequences were the s...Zyxin; Actin; Listeria monocytogenes; Proline-rich repeats; Cell spreading2000
141 Ailion, David CharlesNMR methods for identifying and studying diffusion of different spin species in heteronuclear systemsWe introduce a new dipolar relaxation lime TU)' which characterizes the spin-lattice relaxation of secular dipolar interactions in the presence of a large rf field. Measurements of T]D' are particularly useful for studying slow atomic motions in muitispin systems, since such measurements enable us ...NMR; Nuclear magnetic resonance; Nuclear-spin species; Diffusion; Molecular rotations1978
