Evaluation of predicated array data-flow analysis for automatic parallelization

This paper presents an evaluation of a new analysis for parallelizing compilers called predicated array data-flow analysis. This analysis extends array data-flow analysis for parallelization and privatization to associate predicates with data-flow values. These predicates can be used to derive conditions under which dependences can be eliminated or privatization is possible. These conditions can be used both to enhance compile-time analysis and to introduce run-time tests that guard safe execution of a parallelized version of a computation.As compared to previous work that combines predicates with array data-flow analysis, our approach is distinguished by two features: (1) it derives low-cost, run-time parallelization tests; and, (2) it incorporates predicate embedding and predicate extraction, which translate between the domain of predicates and data-flow values to derive more precise analysis results. We present extensive experimental results across three benchmark suites and one additional program, demonstrating that predicated array data-flow analysis parallelizes more than 40% of the remaining inherently parallel loops left unparallelized by the SUIF compiler and that it yields improved speedups for 5 programs.
AnM-space which is not isomorphic to aC(K) space

We give a new example of anL 1(μ) predual which is not isomorphic to aC(K) space. The space constructed here is a non-separableM-space. By a previous theorem of the author, the separableM-spaces are isomorphic toC(K) spaces.
Modeling thermally thick pyrolysis of wood

Abstract A general model of the pyrolysis of a wood slab is presented and validated with a set of heat release data. The model is applied to particle half-thicknesses from 5 μm to 5 cm , temperatures from 800 to 2000 K , and moisture contents from 0% to 30%. Internal temperatures, pyrolysis rates and yields of tar, hydrocarbons and char are presented. Four pyrolysis regimes are identified, depending on external temperature and particle size: thermally thin—kinetically limited, thermally thin—heat transfer limited, thermally thick, and thermal wave regimes.
Electrostatic potentials of amine nitrogens as a measure of the total electron-attracting tendencies of substituents

Abstract A direct computational means for obtaining a measure of a substituent's total electron-attracting tendency is presented; it involves the calculation of ab initio SCF molecular orbital wavefunctions and electrostatic potentials of substituted amines. The results indicate that the nitrogen lone-pair potential minima of NH 2 -X molecules provide a quantitative index of the total electron-attracting tendencies of the substituents X. A good correlation is shown to exist between the amine potential minima in a group of twenty-four NH 2 -X molecules and the sum of the inductive and resonance substituent constants, σ 1 and σ R , for σ R > 0.
Thermally reversible hydrogels: II. Delivery and selective removal of substances from aqueous solutions

Abstract Hydrogels have been synthesized which exhibit a lower critical solution temperature (LCST) and which shrink and deswell in aquous solutions when the temperature is raised through their LCST. This phenomenon is reversible on cooling below the LCST, when the gels reswell and expand. In this study we have shown that such gels may be used to absorb and/or release (deliver) a variety of biologically and industrially important substances. This action may be simulated by relatively small temperature changes in the environment. We have also shown how a specific binding ligand may be incorporated into the gel for selective binding (and removal or recovery) of specific solutes in aqueous solutions. Important applications of these novel gel systems are proposed for drug delivery, toxin removal, assay of selected solutes, bioprocess or industrial process product recovery and affinity separations in general.

The effect of the joint violation of two assumptions on the size of the F-test under permutation for the randomized block design

The present study attempts to explain the problem encountered by Baker and Collier (1968) of a “humping” of empirical size of F t under permutation for the simple randomized block design for combined levels of variance heterogeneity and block-treatment interaction. Values of comcted nominal size were calculated with the degrees of freedom corrected by two methods: one to correct for variance heterogeneity alone and another to correct for the change in variance heterogeneity induced by the block-treatment interaction. The second method yielded nominal values of size which showed the best agreement with empirical values of size having the “humping” but did not exactly duplicate the peculiar pattern.
Helium isotopic composition of the Tabar-Lihir-Tanga-Feni island arc, Papua New Guinea

Helium abundances and isotopic ratios have been measured in samples of geothermal gases, submarine ultramafic xenoliths, and subaerial mafic phenocrysts and xenoliths from the Tabar-LihirTanga-Feni (TLTF) arc in the Bismarck Archipelago of Papua New Guinea. These unusual volcanoes are produced by adiabatic decompression melting of subduction-modified upper mantle and apparently carry an exceptionally large slab-derived component. They, therefore, provide an ideal setting for studying the role of subducted helium in arc volcanoes. Helium isotopic ratios in the geothermal fluids, submarine xenoliths, and most helium-rich subaerial samples indicate the mantle source regions beneath the Tabar Island Group and Lihir Island have ^3He/^4He ratios of about 7.2 times the atmospheric ratio (R_A), whereas the mantle source for Ambitle Island (Feni Group) in the more southern TLTF arc has a lower ratio of about 6.6 R_A. These ratios are only slightly lower than typical depleted upper mantle values of about 8.5 R_A, indicating that even severely slab-modified mantle wedge carries a relatively minor slab-derived helium component. The systematically lower ^3He/^4He ratios of the Ambitle samples are interpreted to reflect a slightly greater slab-derived helium component. Helium isotopic ratios as low as 2 R_A, which are correlated with low total helium abundances, were observed in subaerial augitic clinopyroxene phenocrysts. Coexisting olivine and sodium-rich acmitic clinopyroxene have higher helium abundances and isotopic ratios. This isotopic disequilibrium between coexisting mineral phases is interpreted as crustal-level addition of a low ^3He/^4He component to an actively outgassing magma from which different mineral phases trap helium sequentially.
Ramsey's theorem and cone avoidance

It was shown by Cholak, Jockusch, and Slaman that every computable 2-coloring of pairs admits an infinite low2 homogeneous set H. We answer a question of the same authors by showing that H may be chosen to satisfy in addition C ≰T H, where C is a given noncomputable set. This is shown by analyzing a new and simplified proof of Seetapun's cone avoidance theorem for Ramsey's theorem. We then extend the result to show that every computable 2-coloring of pairs admits a pair of low2 infinite homogeneous sets whose degrees form a minimal pair.
Harvesting Family Firms' Organizational Social Capital: A Relational Perspective

Organizational social capital (OSC), the goodwill and resources companies gain from their relationships with other companies, enables family firms to assemble the resources (especially knowledge) necessary for successful adaptation. Connecting with new ventures, the vanguard of radical change, is a priority for family firms seeking to achieve survival, profitability and growth. Yet, new ventures are often not well known and their networks are poorly structured, making access to them difficult. Using the relational perspectives on interorganizational relationships, this study proposes that family firms can employ their OSC to reach new ventures. Family firms can invest in these ventures, build profitable business relationships and alliances with them, as well as assist in governing their operations. Data from 779 companies show that family firms are in better positions to harvest their large OSC stocks to connect with new ventures. The results underscore the value of OSC as an important relational resource for family firms.
Spatial and Object Working Memory Deficits in Parkinson's Disease Are due to Impairment in Different Underlying Processes

Working memory maintenance processes for visual-spatial and visual-object information were evaluated in patients with Parkinson's disease (PD). PD patients and controls performed a working memory task with two conditions that differed only in the aspect of the stimuli that the participant was instructed to remember: their locations or shapes. Maintenance processes were investigated by measuring accuracy over 1-s, 5-s, and 10-s delays. Results indicated that patients were impaired in maintaining object information over the delay. In contrast, the patients showed impairment on the spatial condition only when the to-be-remembered stimulus was highly similar in location to the probe, but this impairment was equivalent across the delays, suggesting that this deficit was not due to maintenance impairment. These results suggest that deficits in working memory for spatial and object information are mediated by distinct cognitive processes in nondemented patients with PD and may differ in their pathophysiological basis.
Coactivation of STAT and Ras Is Required for Germ Cell Proliferation and Invasive Migration in Drosophila

Primordial germ cells (PGCs) undergo proliferation, invasion, guided migration, and aggregation to form the gonad. Here we show that in Drosophila, the receptor tyrosine kinase Torso activates both STAT and Ras during the early phase of PGC development, and coactivation of STAT and Ras is required for PGC proliferation and invasive migration. Embryos mutant for stat92E or Ras1 have fewer PGCs, and these cells migrate slowly, errantly, and fail to coalesce. Conversely, overactivation of these molecules causes supernumerary PGCs, their premature transit through the gut epithelium, and ectopic colonization. A requirement for RTK in Drosophila PGC development is analogous to the mouse, in which the RTK c-kit is required, suggesting a conserved molecular mechanism governing PGC behavior in flies and mammals.
Parasympathomimetic effects of fentanyl on the canine sinus node

Abstract The bradycardia coincident with fentanyl administration has been reported to result from a centrally-mediated decrease in sympathetic tone, coupled with a centrally-mediated increase in vagal tone [2,3]. Reitan et al. [8] reported that about 90% of the bradycardic action of fentanyl resulted from an enhancement of vagal efferent traffic from the central nervous system, whereas only 10% resulted from the attenuation of sympathetic neural tone. More recently, Inoue et al. [1] suggested that fentanyl has a rather specific action on individual populations of cardiac vagal fibers associated closely with heart rate changes. The present study was undertaken to analyze (1) whether fentanyl might have a direct negative chronotropic effect upon the sinus node, irrespective of autonomic neural input to the node and (2) whether fentanyl might potentiate the actions of vagally-released acetylcholine on the sinus node. Mongrel dogs (n = 10) were premedicated with morphine sulfate (3 mg/kg) and anesthetized with alpha chloralose (75 mg/kg). Animals were intubated and ventilated using a positive pressure pump. The femoral vein and artery were catheterized respectively for the maintenance of fluid balance and measurement of arterial pressure. Both vagi were isolated in the cervical region and transected. A right thoracotomy was performed and a pericardial cradle was constructed. Both stellate ganglia were exposed and the ansae subclavia were sectioned bilaterally. This procedure (coupled with bilateral vagotomy) has been shown to be analogous to total cardiac denervation [7]. Electrograms were recorded from the sinus node, right atrium, right ventricle and His bundle and a lead II electrocardiogram was recorded.

Around the lander in 80 sols

ARES VALLIS, MARS—It's like a whole new landing site. One advantage of Mars Pathfinder over its Viking predecessors is the rover, Sojourner, which is proving to be a capable miniature geologist. Now more than 80 Martian days—called Sols, each of which is approximately 24 hours, 37 minutes long— into the mission, Sojourner continues to provide new perspectives on the Pathfinder landing site. Sojourner is giving the engineering team a wealth of data and experience that will be useful when the next rover reaches the red planet in 2002. A prime example of the new perspectives provided by the rover came on Sol 76 (September 19, 1997), when Sojourner peeked behind the 0.2–0.8 m-high boulders of the “Rock Garden.” This vista contained a beautiful set of wind-blown drifts that were not visible to the lander's stereo imaging system (Figure 1). The drifts occur on the downwind (southwest) side of a cluster of imbricated boulders and are analogous to the variety of wind-tails seen behind cobbles and pebbles throughout the landing site.
Selective induction of release of hydrolases from Crassostrea virginica hemocytes by certain bacteria

Abstract Serum-free Crassostrea virginica hemocytes were maintained in a medium to which was added one of four species (or strains) of bacteria: Escherichia coli, Enteric Group 17 bacteria, Micrococcus roseus, and Klebsiella oxytoca. The hemocytes were exposed to each type of bacteria for 1, 2, 3, and 4 hr after which they were removed and the activities of two hydrolases, acid phosphatase and α-mannosidase, in the maintenance medium were ascertained. It was determined that at 25°C both E. coli and Enteric Group 17 bacteria induced a linear release of both enzymes from hemocytes into the maintenance medium while neither M. roseus nor K. oxytoca stimulated enzyme release. It is concluded that there is selective induction of release of hydrolases from oyster hemocytes by only certain bacteria.
Thermal expansion of vacuum plasma sprayed coatings

Metallic Cu-8%Cr, Cu-26%Cr, Cu-8%Cr-1%Al, NiAl and NiCrAlY monolithic coatings were fabricated by vacuum plasma spray deposition processes for thermal expansion property measurements between 293 and 1223 K. The corrected thermal expansion, (DL/L(sub 0) varies with the absolute temperature, T, as (DL/L(sub 0) = A(T - 293)(sup 3) + BIT - 293)(sup 2) + C(T - 293) + D, where, A, B, C and D are thermal, regression constants. Excellent reproducibility was observed for all of the coatings except for data obtained on the Cu-8%Cr and Cu-26%Cr coatings in the first heat-up cycle, which deviated from those determined in the subsequent cycles. This deviation is attributed to the presence of residual stresses developed during the spraying of the coatings, which are relieved after the first heat-up cycle. In the cases of Cu-8%Cr and NiAl, the thermal expansion data were observed to be reproducible for three specimens. The linear expansion data for Cu-8% Cr and Cu-26%Cr agree extremely well with rule of mixture (ROM) predictions. Comparison of the data for the Cu-8%Cr coating with literature data for Cr and Cu revealed that the thermal expansion behavior of this alloy is determined by the Cu-rich matrix. The data for NiAl and NiCrAlY are in excellent agreement with published results irrespective of composition and the methods used for processing the materials. The implications of these results on coating GRCop-84 copper alloy combustor liners for reusable launch vehicles are discussed.
Sexual Assault Perpetrators' Alcohol and Drug Use: The Likelihood of Concurrent Violence and Post-Sexual Assault Outcomes for Women Victims

Addressing sexual assault requires policy and practice responses that are well-informed and empirically-grounded. This study examines the impact of perpetrators' drug and alcohol use during and after sexual assault. A representative sample of women, who responded to a random digit dialing survey, and reported that they were sexually assaulted at some time in their lives were utilized. The survey questions were drawn largely from The National Violence Against Women (NVAW) Survey (Tjaden 1996), and a series of binary logistic regressions was conducted to determine the impact of perpetrators' alcohol and drug use on violence before and after the assault. Findings indicate that perpetrators' alcohol or other drug use at the time of the assault resulted in a greater likelihood of concurrent violence, including hitting, slapping, kicking, use of a weapon, threats to harm or kill, and physical injury during the assault, and as a result, assault victims experienced more time lost from work, school, home duties, and recreation. Both these impacts occurred regardless of the relationship of the perpetrator to the victim, location of the sexual assault, or the victim's ethnicity. This information assists advocates and policy makers in prevention efforts where sexual violence is more likely to emerge.
Effects of deposition rate and substrate temperature on the orientation and the growth of YBa/sub 2/Cu/sub 3/O/sub x/ thin films

The authors report in situ studies of film growth by sputtering using synchrotron X-rays. The structure and growth habit of YBa/sub 2/Cu/sub 3/O/sub 7/ (YBCO) thin films deposited on [100] SrTiO/sub 3/ in a miniature, faced-magnetron sputtering system have been investigated. A combination of the substrate temperature and the deposition rate determines whether the film grows along the a, c, or multiple axes. At low substrate temperatures and low deposition rates, the films grow preferentially along the a-axis, In contrast, higher substrate temperatures and high deposition rates favor c-axis-oriented film growth with some admixture of [220]. The X-ray diffraction peaks were monitored in real time, revealing that a-axis- and c-axis-oriented grains nucleated on the surface of the [100] SrTiO/sub 3/ between 625 degrees and 765 degrees C, although the volume fraction of each orientation was temperature dependent. The structural quality of the a-axis films is superior to that of the c-axis films. The best a-axis films (deposited at 685 degrees C) had a rocking curve width of 0.08 degrees , which is 10 times smaller than that for the c-axis films (deposited at 800 degrees C). A shift of the [007] and [200,] peak positions during deposition was observed. The shift in the [007] peak is larger than that for the [200] peak. Defects in the c-axis films were observed, not only at the interface between the film and the substrate, but also on the upper surface of the (final) film; the latter seems to be inherent and is more severe in the films considered.
Two stage separation and the analysis of international investment

Economists have long been aware that it is possible to construct an optimal market bond from an arbitrary collection of risky assets independent of an investor's utility function; this is the Sharpe Separation Theorem that first appeared in the Journal o f Finance in 1964. Many subsequent applications of this independence to optimal international investment have extended this separation, without theoretical justification, to a second stage: autarkic domestic and foreign market bonds are first computed individually before a worldwide market bond is constructed entirely from the resulting amalgomated assets. Studies published in the Journal o f Political Economy by Lee (1969), Clark and Haas (1972), and Kouri and Porter (1974) are all notable entries on a longer list of such applications. The purpose of the present note is to report on the theoretical validity of this two stage procedure in the analytical model that produced Sharpe's original result. The full proof of our conclusion is available from the authors. We considered a domestic investor in a five asset world. The first was a safe asset, the domestic currency, with a certain return of zero. We also allowed four risky assets, two domestic and two foreign, whose returns were all jointly distributed. Casting these assets into a mean-variance framework, we first computed the optimal autarkic bonds for the domestic and foreign sectors. The eventual two stage market bond was then constructed entirely from these two autarkic bonds. The Sharpe Theorem, however, instructs us that the optimal market bond must be constructed from all four risky assets taken together in a single stage. By comparing the appropriate first order condition for the ultimate two stage bond with a combined first order condition for the Sharpe procedure, we saw that two stage separation is valid only if: (i.) the autarkic bonds consist of a single asset; and (ii.) the correlations between the chosen domestic (foreign) asset and the other domestic (foreign) asset, on the one hand, and between the chosen domestic (foreign) asset and the inferior foreign (domestic) asset, on the other hand, are identical. These conditions are obviously quite restrictive, and it is unlikely that they are satisfied in any realistic application to international investment. Mr. Egy is currently undertaking a reconstruction of the analyses in which two stage separation have been employed. Our result certainly suggests that such an enterprise is in order.
Transgenic Monkeys Produced by Retroviral Gene Transfer into Mature Oocytes

Transgenic rhesus monkeys carrying the green fluorescent protein (GFP) gene were produced by injecting pseudotyped replication-defective retroviral vector into the perivitelline space of 224 mature rhesus oocytes, later fertilized by intracytoplasmic sperm injection. Of the three males born from 20 embryo transfers, one was transgenic when accessible tissues were assayed for transgene DNA and messenger RNA. All tissues that were studied from a fraternal set of twins, miscarried at 73 days, carried the transgene, as confirmed by Southern analyses, and the GFP transgene reporter was detected by both direct and indirect fluorescence imaging.
A Cool Drink on a Hot Day – Hospital-Acquired Legionella Pneumonia

ISSUE: A proactive Legionella control program combining continuous disinfection of the water distribution system, environmental sampling and active case detection was established in a large urban hospital in the early 1990's. While cases of community-acquired disease are generally seen in the area during the rainy spring months, no patients had been identified with hospital acquired infection until Sept. 2005, after a particularly hot, dry summer. PROJECT: In order to prevent additional infections, all systems were immediately reviewed. Routine cultures of hospital sinks and showers had occasionally shown low levels of Legionella pneumophila in less than 30% of samples collected. There were no disruptions in the water supply and readings from the copper-silver ionization system were within range. Although the hospital's hot water supply is disinfected by the system, the cold water supply is not treated since the cooler water is not considered to be at increased risk for Legionella multiplication. After the case was identified, cultures were collected from additional water sources, including the new state of the art ice and water dispenser that served the patient unit. Maintenance personnel provided documentation that the unit was cleaned and sanitized as per manufacturer's instructions and provided the service manual for review. RESULTS: Cultures collected from the dispenser's water chute showed confluent growth of Legionella pneumophila serogroup 1. Isolates from the environment and patient submitted to a reference lab for Pulsed-Field Gel Electrophoresis (PFGE) had identical patterns. Periodic cleaning procedures in the manual stated that a chlorinated cleaning solution (200 ppm available chlorine) should be used, followed by a sanitizing solution (50 ppm). Since this sequence was reversed from our usual disinfection practices, the manufacturer of the recommended cleaner was contacted. The company was unaware that their product was mentioned and confirmed that these steps were incorrectly listed. Another factor leading to the disinfection failure was identified- maintenance personnel did not realize that the solutions were to be 75°F-125°F. LESSONS LEARNED: During the hot summer months, water coming in from the municipal water supply was reported to be unusually warm, theoretically allowing small numbers of Legionella in the water to multiply. While the preventative maintenance schedule was being followed according to the manufacturer's instructions, the incorrect dilution sequence and low temperature of the solution used potentially allowed the interior surfaces of the machine to develop a biofilm layer containing Legionella - a problem common in our hard water area. While we thought that our high-tech, proactive system was working wonderfully, all it took was a cool drink on a hot day to break our winning streak of Legionella prevention. And an unfortunate patient with a history of aspiration.
Three-dimensional human somatosensory evoked potentials☆

Abstract Median nerve somatosensory evoked potentials were recorded from 30 normal adults using conventional scalp derivations and an orthogonal bipolar surface electrode montage. This allowed the determination of the spatial orientation of the hypothetical centrally located equivalent dipole derived from the evoked response recorded in 3-dimensional voltage space. The 3-dimensional voltage trajectory describing changes in equivalent dipole orientation and magnitude revealed 4 major apices between 5 and 25 msec, 3 of which corresponded to the traditional P14, N20 and P25 peaks. A fourth apex at 17 msec was not as evident in the conventional recordings and signaled a transition from a vertical P14–N18 generator process to a horizontal N20 generator process. The normal within- and between-subject variability of trajectory apices, segments and planes are described, along with the theoretical and practical implications of this recording technique.
An eco-compatible process for the depuration of wastewater from olive mill industry

Olive mill wastewater (OMW) is the by-product of olive oil industrial production. It is characterized by a dark brownish color and a strong odor and is considered one of the most polluted agricultural wastes. In this paper we briefly describe an innovative procedure for the depuration of olive mill wastewater. With this procedure it is also possible to recover valuable substances such as phenolic compounds which have important commercial applications: they can be used in the prevention of cardiovascular disease and as antiviral, antioxidant and antitumor agents. The proposed OMW treatment uses two different packed vegetable matrices which remove most of the pollutant substances by absorption. After filtration of OMW on the matrices the pollutant load of the waste is greatly reduced: the organic content (COD) is reduced more than 80% and the phenol compounds are completely removed.
Toxin Produced by Malleomyces pseudomallei.

Summary1. Malleomyces pseudomallei produced in broth cultures a toxin which was lethal for both mice and hamsters. 2. Intradermal inoculation of bacteria-free filtrates of broth cultures of Malleomyces pseudomallei produced an edematous, erythematous and hemorrhagic lesion in normal guinea pigs. Boiled filtrates produced only delayed erythema and edema, suggesting the presence of a thermolabile component which was responsible for the hemorrhagic lesion. 3. The potency of the toxin did not appear to be related to the colonial morphology.
A randomized study of the efficacy of the PROPATH Program for patients with Parkinson disease.

Objectives: To assess (1) the effects of the PROPATH Program, a health management program designed for patients with Parkinson disease, on perceived general health and psychological well-being and satisfaction with medical care, (2) utilization of health care resources by patients with Parkinson disease, and (3) physician impressions of the PROPATH Program. Design: Patients were randomized to receive either the PROPATH Program in addition to usual care or usual medical care only. All patients and their physicians completed periodic questionnaires designed to assess the study variables. Setting: Staff model health maintenance organization from June 1992 through June 1993. Patients: Forty-six English-speaking patients diagnosed with Parkinson disease of Hoehn-Yahr stages I through IV. Results: Enrollment in the PROPATH Program resulted in a statistically significant improvement in patient perception of general health and psychological well-being after 1 year. There was no significant difference in patient satisfaction with medical care or utilization of health care resources. The large majority of physicians did not find the PROPATH Program to be helpful for development of a treatment plan, management of the illness, identification of problems sooner than by usual treatment, or identification of drug side effects. Conclusions: The PROPATH Program may play a useful role in assisting patients to deal with the psychological aspect of Parkinson disease by improving perception of general health and psychological well-being. The program had no significant effect on patient satisfaction with medical care or medical resource utilization.
On a coefficient problem for nonvanishing H p functions

It has been conjectured by Hummel, Scheinberg and Zalcman that if f(z) ≈ a 0 + a 1 z + a 2 z 2 + … is a nonvanishing H p function with then for all n⋝ 1 and 1 < p < ∞ where 1/p + 1/q = 1. Using the Pontryagin Maximum Principle we solve a related extremal problem which proves the conjecture in the case n = 1 and in the case of arbitrary n ⋝ 2 provided a m = 0 for 1 m < (n 1)/2.
Oscillation of Systems of Neutral Equations with Variable Coefficients

Consider the system of the neutral delay differential equations (1) where P(t) = (pij(t)), Q(t) = (qij(t)) and R(t) = (rij(t)) are n x n matrices for t ≧ 0 and the delays τ, σ and ϱ are nonnegative numbers. We obtain sufficient conditions for the oscillation of all solutions of (1) under the following hypotheses:
Powder Patterns from Nanocrystal Lattice Images

Fringes in electron phase, and Z, contrast images contain (among other things) the same “Fourier phase information” used in conventional darkfield imaging to locate objects of selected periodicity. However, conventional darkfield apertures often vignette in azimuth, and/or cannot distinguish frequencies whose spacing differs by less than 10%. Lattice images of multiple nanocrystals facilitate an alternate approach to analyzing both fringe abundances (illustrated here), and cross-fringe correlations (discussed in a separate abstract). At the University of Missouri Rolla, AgPt nanoparticles with high aspect ratio [1] were grown in "necklace form" with crystal links 3-5 nm long and 2-4 nm in breadth, separated by occasional "large" equant knots (up to perhaps 10 nm in diameter). The question we address here: Can HREM imaging provide insight into segregation between Ag and Pt across the various components of these nanochains, given that Ag and Pt have strong (111) diffraction peaks at spatial frequencies of 2.36A and 2.26A respectively [2], making it impossible to distinguish them grain by grain e.g. by darkfield imaging? Fig. 1 is a 240,000x magnified image taken with a Phillips EM430ST microscope, which shows the chain-knot strands streaming off of a large clump of silver. Using Adobe Photoshop with IPTK plugins and/or ImageJ, we are able to take power spectra of selected regions of specimen images digitized at 2400 dpi, and measure spatial frequencies (Figures 2 and 3). By taking many individual power spectra of various parts of chains and knots and measuring spatial frequencies, a histogram of spatial frequencies associated with links and knots was then compared to powder diffraction profiles of Ag and Pt. Fringe spacings thus allow one to correlate with each object type the range of randomly encountered Bragg spacings. Interesting patterns emerge from the data in Fig. 4. For example, the profiles in Fig. 4 suggest that the knots are largely Ag. Our analysis also suggests that the chains have a sharp peak in lattice parameter, quite near the 2.26A peak for Pt though shifted slightly towards the higher lattice spacing of Ag. Projection broadening of fringes due to the small (e.g. 2nm) grain cross-sections is one possible explanation. Specimens with less similar structures would of course make identification of trends even easier. Although the analysis described here was done by manually analyzing power spectrum peaks in 136 individual grains, the technique also lends itself to automation by simple azimuthal intensity averaging, provided regions for differential comparison can be otherwise flagged for the computer. Polycrystalline films in profile, with hopelessly overlapping grains, can also be analyzed in this way. The usefulness of this strategy will increase with the availability of large digitized images containing projected lattice fringe information.
Electron and proton transfer reactions of simple aldehyde and ketone radical cations and their enol and distonic isomers

Abstract The reactivity of the keto and enol isomers of the acetaldehyde and acetone radical cations and the keto, enol and distonic isomers of the propanal radical cation was examined in the gas phase by using Fourier-transform ion cyclotron resonance mass spectrometry. The results obtained show that these radical cations do not readily undergo isomerization within a gas-phase collision complex. Further, the ions favor electron transfer to proton transfer whenever the former reaction is thermodynamically accessible. This reaction can occur either directly by abstraction of an electron by the radical cation or indirectly by a more complex mechanism that is likely to involve energetically favorable proton and hydrogen atom transfers within the ion-molecule complex (a H + /H shuttle). The above knowledge can be utilized in the differentiation of the keto, enol, and distonic isomers of simple carbonyl-containing radical cations.
β-SiH rich zinc silyl compounds: Reductive elimination and β-hydrogen abstraction

Abstract The two-coordinate compound Zn{Si(SiHMe2)3}2 (1) is generated by the reaction of ZnCl2 and 2 equiv. of KSi(SiHMe2)3, but this species undergoes reductive elimination to produce (Me2HSi)3Si–Si(SiHMe2)3 and metallic zinc over 48 h at room temperature. The transient disilylzinc compound is stabilized by a neutral N-heterocyclic carbene (NHC) 1,3-di-t-butylimidazol-2-ylidene (ImtBu) or the chelating N-donor ligands 1,2-dipyrrolidinoethane (dpe) or 2,2′-bipyridine (bipy). The one-bond silicon-hydrogen coupling constants (1JSiH) and the infrared stretching frequencies (νSiH) of these disilyl zinc compounds indicate that the zinc center and silyl ligand interact through a classical 2-center-2-electron bond, and the β-SiH groups do not show evidence of nonclassical interactions with the zinc center. Still, the β-SiH groups undergo β-hydrogen abstraction rather than silyl group abstraction upon reaction with the Lewis acid B(C6F5)3 to give the corresponding silylzinc hydridoborate compounds.
Transient bandwidth analysis of photoconductive microwave switches implemented in the OMEGA pulse shaping system

Abstract Previous measurements have demonstrated that the greatest limitation on the pulse-shape bandwidth of the Laboratory forLaser Energetics' OMEGA laser's driver line occurs within the electrical pulse-shaping subsystem during transmission throughthe photoconductive switches. A comparison of the spectral content of the shaped pulses before and after the switch indicatedthat the switch 3-dB bandwidth was approximately 3 GHz. Since this was the limiting bandwidth ofthe system, it was necessaryto measure and improve the microwave transmission through the switches. This challenge required a novel measurement scheme,described in this paper, to allow accurate optimization of the switch parameters that affect bandwidth. The switches werecharacterized and their 3-dB transmission bandwidth was expanded to over 5 GHz, thereby improving them beyond the systembandwidth limits.Keywords: Photoconductive switch, time-varying microwave transmission bandwidth, transient measurement1. INTRODUCTIONThe OMEGA laser fusion program at the University of Rochester's Laboratory for Laser Energetics calls for complex,temporally shaped optical pulses incident on fusion targets.1 The rise-time and pulse-duration specifications of these opticalpulses dictate a pulse-shaping system bandwidth of approximately 0. 1 to 10 GHz. The high-frequency end of the bandwidth isdetermined by the allowable maximum rise time and fall time ofthe optical pulse shape and the low-frequency end is determinedby (inversely proportional to) the temporal duration ofthe opticalpulse. The opticalpulses are created by impressing an electricalequivalent of the desired optical envelope onto an optical pulse by using an integrated-optics Mach-Zehnder interferometricelectro-optic modulator, as shown in Fig. 1 .
Counseling regarding human immunodeficiency virus-antibody testing: An international method of knowledge and risk assessment

Abstract The purposes of this paper are to summarize issues regarding the administration of HIV-antibody testing and to present an interactional method of communicating information to patients regarding AIDS, transmission of HIV, and the meaning of HIV-antibody test results. HIV-antibody testing, when associated with pretest and posttest counseling, can be used to educate individuals at risks for HIV infection and AIDS and can serve as an intervention to prevent the spread of HIV. We have used the interactional method with over 250 outpatients who sought treatment for cocaine dependency. We found the method to be easily administered by medical and nonmedical staff and well accepted by patients.
Morphology and biology of a nest-producing mite, Bakericheyla chanayi (Acarina: Cheyletidae)

Bakericheyla chanayi (Berlese & Trouessart) is recorded from the following fringillid birds in California: Zonotrichia leucophrys nuttalli Ridgway, Z. I. gambeli (Nuttall), Z. I. pugetensis (Grinnell), Z. atricapilla (Gmelin), and Pipilo erthrophthalmus (L.) subspecies. The female is redescribed. The male, nymph, and larva are described for the 1st time. The mites are bloodsucking parasites which construct “nests” of silky fibers on the skin of the host. In the nests occur all stages of the mite. Incidence of infestation is higher in migratory subspecies of white-crowned sparrows than in the resident species in California. The health of heavily infested birds is impaired by the mites.
A heterobimetallic metal–organic framework with tunable reactive metal sites: synthesis, characterization, and reactivity

A technique for preparing heterobimetallic frameworks with tunable metal sites is demonstrated by the synthesis of a new two-dimensional metal–organic framework that is constructed from tetra(4-carboxyphenyl)porphyrin and Cd(II) species. The solid can be prepared in the presence of other divalent transition metals to yield the same framework with the smaller metal ions occupying the porphyrin ligands.
Relationship of alpha MSH-specific neurons to the arcuate opiocortin neuronal system as determined by dual antigen immunocytochemical procedures

Abstract The cross-immunoreactivity, topography, and fiber projections of the alpha MSH-immunoreactive specific neurons in the forebrain of the rat appear to be distinctly different from that of the neurons in the hypothalamic arcuate opiocortin system. The cell bodies, immunoreactive only to α-MSH, have a specific pattern of distribution in the dorsal and lateral hypothalamic regions from the level of the retrochiasmatic region to the premammillary area of the posterior hypothalamus. Immunoreactive fibers of these cells appear to extend into regions of the cerebral cortex and hippocampus. An antomical relationship between the immunostained fibers and/or terminals of the arcuate opiocortin pool of neurons and the α-MSH-immunoreactive perikarya is described utilizing the ABC (Avidin-Biotin-Peroxidase Complex) and ABC-GO (Glucose Oxidase) or glucose oxidase-antiglucose oxidase complex methods of immunocytochemistry in which two tissue antigens with contrasting colors are demonstrated in the same tissue section.
On the margins of the malestream (or, they still don't get it, do they?): Feminist analyses in criminal justice education

This paper is a critical review of the Fall 1992 issue of the Journal of Criminal Justice Education (JCJE), which focused on women in criminal justice education. The review concentrates on three educational areas: curriculum, pedagogy, and the campus climate for students and faculty. Feminism has had a clear effect in each of these areas, but it has not been enough to transform criminology/criminal justice education so that gender is a central organizing theme. Feminist criminology/criminal justice education seems to remain at the margins of the “male-stream.”
A non-Newtonian model of flow in forward and backward pumping screw regions of a modular tangential counter-rotating twin-screw extruder

Abstract The flow of a non-Newtonian fluid in forward and backward pumping elements of a tangential counter-rotating twin-screw extruder has been modeled. A simulation has been carried out for a power law fluid model using hydrodynamic lubrication theory and a modified flow analysis network procedure. The model predicts pressure fields from which mean flux fields and screw characteristic curves may be computed. Large backward leakages between the screws are predicted for the forward pumping elements. This leakage induces distributive mixing. The backward flow is much greater for staggered as opposed to matched screw flights. The pumping characteristics are much less than for two equivalent single-screw extruders. The non-Newtonian behavior reduces the relative amount of backward leakage between the screws but, as in a single-screw extruder, non-Newtonian viscosity behavior reduces pumping ability. For backward pumping screws, there is a forward surging flow between the screws. The screw characteristic curves indicate negative pressure gradients for positive fluxes. These screw characteristic curves are much less non-linear.
Hungarian Women’s Holocaust Life Writing in the Context of the Nation’s Divided Social Memory, 1944-2014

In this paper, in commemoration of the seventieth anniversary year of 1944 in Hungary, I explore selected women’s Holocaust diaries, memoirs, letters, and other less studied documents, such as recipe books, all written during the war, which can provide invaluable resources for understanding the experiences of the victims of war, by personalizing the events and helping to write the obscure into history. At the same time, such documents allow historical voices of the period to provide testimony in the context of the divided social memory of the Holocaust in Hungary today. I will first discuss several Hungarian diaries and “immediate memoirs” written right after liberation, among others, that of Eva Heyman who began writing her diary in 1944 on her thirteenth birthday and wrote until two days before her deportation to Auschwitz, where she perished. I will then discuss two recently published volumes, the Szakacskonyv a t ulelelesert (2013), which contains the collected recipes that five Hungarian women wrote in a concentration camp in Austria, along with an oral history of the life of Hedwig Weiss, who redacted the collection. Finally, I will refer to the postmemory anthology, Lanyok es anyak. Elmeseletlen tortenetek [‘Mothers and Daughters: Untold Stories’] (2013), where thirty five Hungarian women, some themselves child survivors, others daughters of survivors, write Holocaust narratives in which their mothers’ lives become the intersubject in their own autobiographies, underscoring the risks of intergenerational transmission, where traumatic memory can be transmitted (or silenced) to be repeated and reenacted, rather than worked through.
Predictive Speed Control of a Two-Mass System Driven by a Permanent Magnet Synchronous Motor

This paper presents a predictive strategy for the speed control of a two-mass system driven by a permanent magnet synchronous motor (PMSM). The proposed approach allows to manipulate all the system variables simultaneously, including mechanical and electrical variables in a single control law. The state feedback is achieved with a reduced order extended Kalman filter, which observes the non-measured variables as well as reduces the impact of measurement noise. The performance of the control strategy is shown through simulation and experimental results in a 4 [kW] laboratory prototype.
Screening cotton germplasm for root growth potential

Abstract The differential influence of root systems on plant productivity under field conditions has been difficult to evaluate. A field experiment was devised using three different row spacings (101, 152 and 203 cm) to screen cotton ( Gossypium hirsutum L.) germplasm for root growth potential based on the relative ability to explore additional soil volume for water. The basic hypothesis was that lint yield increased as the available soil volume increased, provided that the genotype has the potential to produce the root system capable of taking advantage of the additional water resources. Seventy-seven entries from various germplasm backgrounds were grown to maturity in a replicated field test and lint yield was measured. The results demonstrated that root growth potential, expressed as lint yield per centimeter of row spacing ( i.e. the slope of the linear regression analysis), was significant across the entries. This indicated that variation exists for the extent of root growth of the germplasm. Additional studies using ten high and ten low rooting potential genotypes revealed that there was no significant relationship between rooting potential and plant maturity. This approach offers a novel system for screening germplasm for potential field productivity based on diverse rooting characteristics.
