The peptide sequential assignment algorithm presented here was implemented as a macro within the CONnectivity TRacing ASsignment Tools (CONTRAST) computer software package. The algorithm provides a semi- or fully automated global means of sequentially assigning the NMR backbone resonances of proteins. The program's performance is demonstrated here by its analysis of realistic computer-generated data for IIIGlc, a 168-residue signal-transducing protein of Escherichia coli [Pelton et al. (1991) Biochemistry, 30, 10043-10057]. Missing experimental data (19 resonances) were generated so that a complete assignment set could be tested. The algorithm produces sequential assignments from appropriate peak lists of nD NMR data. It quantifies the ambiguity of each assignment and provides ranked alternatives. A 'best first' approach, in which high-scoring local assignments are made before and in preference to lower scoring assignments, is shown to be superior (in terms of the current set of CONTRAST scoring routines) to approaches such as simulated annealing that seek to maximize the combined scores of the individual assignments. The robustness of the algorithm was tested by evaluating the effects of imposed frequency imprecision (scatter), added false signals (noise), missing peaks (incomplete data), and variation in user-defined tolerances on the performance of the algorithm.

- Abstract
“Bury me standing. I must be buried standing.”Powers, the follow-up to John Olson's Shade (“a must-read for those who enjoy Ted Dekker and Frank Peretti” —Publishers Weekly), introduces a sheltered Gypsy girl named Mariutza. Her grandfather utters a mysterious last request before dying in her arms after being shot by ten cloaked men.Those same men die before her eyes, but strange powers continue to pursue Mari through the swamps of southern Louisiana where she has always hidden from “the Badness.”The whole world seems to join in the chase—helicopters, soldiers, government agents, and the police are all trying to kill her. Mari's only hope of survival is to find Jaazaniah the Prophet, the mythical hero of her grandfather's bedtime stories. But she has never been outside the swamp or known other humans besides her grandfather and one teacher. How can this lone girl survive the bewildering world of men long enough to find a prophet who might not even exist?

- Abstract
'You will not fear the terror of the night.'—Psalm 91A monstrous waking nightmare is pursuing graduate student Hailey Maniates across San Francisco to Golden Gate Park where she is rescued by a towering homeless man. She seems able to read her rescuer's mind, but is it just a delusion? Doctors diagnose her as a paranoid schizophrenic and attempt to prescribe away her alleged hallucinations. But too many questions remain around Hailey and the man who saved her. He appears to suffer from her same mental condition and is convinced that some type of Gypsy vampire is trying to kill them both.Against reason, Hailey finds herself more and more attracted to this strange man. But what if he is a fantasy? What if he is the monster?Endorsements:'From its stunning first scene to its heartwarming last, Shade is a striking tale of mystery and danger that kept me hooked. This is Olson's finest work yet, and reading it, one gets the feeling he's just getting warmed up.'Robin Parrish, author of Relentless and Merciless'Unseen enemies. Questioned sanity. The weighing of reality. All the things I like in a book! The shadows are not silent. I lost sleep over this book. I got goose bumps from this book. The kind of scary that you crave and cringe at, Shade offers up a monster made more frightening by its originality. Thanks a lot, John Olson--because of you, I will not walk alone at night for a long time to come.'Tosca Lee, author of Demon: A Memoir and Havah: The Story of Eve'John B. Olson is a seasoned storyteller, and Shade is quite a story! As the heat turns up, and as menacing tones and brooding characters abound, the theme of God's grace boils to the surface. A few years back, Olson gave us a new twist on Jekyll & Hyde; now he puts his own fast-paced spin on the Dracula story. I can only hope there's a sequel in the works!'Eric Wilson, author of Field of Blood and A Shred of Truth'Shade is a smart, gripping thriller. John B. Olson whips you along in a breakneck odyssey through a hellish paradise lost--and keeps you up all night doing it.'Melanie Wells, author of My Soul to Keep and When the Day of Evil Comes'Things that go bump in the night are not all figments of overwrought imaginations or evidence of mental illness. As our heroine discovers, evil personified preys on the ignorance of its victims. Lock your doors and windows, leave the lights on, and hunker down for a splendid, spine-chilling read.'Donita K.

The knowledge of the interfacial energetics (band edge potentials, doping density, and formal reduction potential) of a semiconductor electrode immersed in a solution containing a redox couple is crucial to the interpretation of electron-transfer rates. The techniques used for the acquisition of impedance data simultaneous with current-potential measurements at both n- and p-type WSe/sub 2/ electrodes with doping densities spanning 3 orders of magnitude are described. The band edges were found to be energetically stable in the presence of different redox couples at differing concentrations. Evidence is presented to support the technique of simultaneous interfacial energetic determinations and to defend the validity of carefully executed impedance determinations of interfacial energetics. Simultaneous current-potential and impedance-potential data are reported for decamethylferrocene/sup +,0/ and ferrocene/sup +,0/ at an n-WSe/sub 2/ electrode with a doping density of 2.8 /times/ 10/sup 17/ cm/sup /minus/3/. The behavior of these two outer-sphere redox couples is dramatically different with respect to the shape of the current-potential curves and the dependence of the current on the concentration of solution species. The exchange current densities are compared to theoretical predictions.

A linear correlation of existence metabolism (Mkcal = kcal·bird-1·day-1) with temperature (T = °C) was obtained for winter acclimatized Field Sparrows (Spizella pusilla) on a 10-h photoperiod (males: Mkcal = 15.59-0.285T; females: Mkcal = 14.69-0.261T). A curvilinear relationship was obtained for summer acclimatized birds on a 15-h photoperiod (males: Mkcal = 16.40 + 0.0001T3 - 0.0002T2 - 0.3662T; females: Mkcal = 15.87 + 0.0036T2 - 0.3911T). Significant differences between summer- and winter-acclimatized birds occurred only at temperatures below 0°C. The lower limit of temperature tolerance was -13° to -14°C under a constant 10-h photoperiod and under fluctuating outdoor conditions and was somewhat lower under a constant 15-h photoperiod. The upper limit of temperature tolerance was about 41°C in the summer. With caged birds under fluctuating outdoor conditions, there was an increase in metabolized energy, existence metabolism, body protein, weight, and lipid content in the autumn and a decrease in the spring. During cold waves in winter, there was commonly an immediate drop in weight before increased metabolized energy brought recovery. In half of the birds, recovery was incomplete and mortality resulted. Coefficients of food utilization varied from 0.71 under a 10-h photoperiod to 0.79 under a 15-h photoperiod and from 0.72 to 0.86 under outdoor conditions. With death from cold or heat stress there was a loss of water, lipids, and proteins. The loss of water was greater under heat stress. Nocturnal activity (Zugunruhe) developed in a different pattern in spring than in autumn and was not accompanied by premigratory fattening in the spring. In several respects, the metabolic and behavioral responses of the Field Sparrow are intermediate between those of long distance migrants and permanent residents, indicating that they may be evolving from a migratory to a nonmigratory status.

The San Fernando Earthquake of February 9, 1971, caused severe damage to aboveground steel pipe sections of the two aqueducts serving Los Angeles. This damage resulted from different ground movement which displaced the pipe supports. The movements caused buckling and rupturing at a welded slip joint, separation of several mechanical couplings, and shifting of concrete anchor blocks on the 77-in. (195.6-cm) diam welded steel Second Los Angeles Aqueduct. The riveted 99-in. (251.5-cm) diam First Los Angeles Aqueduct was misaligned laterally and longitudinally. Repair to the facilities consisted of removal of buckled sections, installation of new saddle supports, replacement of mechanical couplings, and installation of rock anchors. Movement sensors were installed across mechanical couplings and load cells were attached to the rock anchors to measure changes in load. Recommendations are made to reduce potential seismic damage to aboveground pipelines to permit their continued operation following earthquakes.

The preparation and electrochemical characterization of n-type and p-type tungsten diselenide (WSe 2 ) crystal electrodes with doping densities ranging from 5×10 15 to 3×10 19 cm −3 is reported. The growth of these layered crystals was accomplished using chemical vapor transport. The doping of the crystals is described; it was found that using Cl 2 as the transport agent and rhenium as dopant produced n-type crystals, while the p-type were obtained using I 2 as transporting agent and niobium as dopant. The exceptional stability and the layered lattice structure of these crystals are desirable features not found in most small bandgap semiconductors. These features permit accurate electrochemical (Mott-Schottky) determinations of the interfacial energetics. Electrodes prepared from these crystals were characterized electrochemically, which indicated ideal behavior of the space charge region (SCR) over wide range of potential and frequency, and photoelectrochemically, which revealed fill factors from 0.37 to 0.65. Doping densities, within a given batch of crystals, were found to be relatively uniform. Band edge potentials did not shift due to doping, frequency or the presence of metallocene redox couples. The utility of this series of semiconductor electrodes for fundamental studied is discussed.
