Risk, uncertainty and prophet: The psychological insights of Frank H. Knight

Full Text Available Economist Frank H. Knight (1885--1972 is commonly credited with defining the distinction between decisions under ``risk'' (known chance and decisions under ``uncertainty'' (unmeasurable probability in his 1921 book Risk, Uncertainty and Profit. A closer reading of Knight (1921 reveals a host of psychological insights beyond this risk-uncertainty distinction, many of which foreshadow revolutionary advances in psychological decision theory from the latter half of the 20th century. Knight's description of economic decision making shared much with Simon's (1955, 1956 notion of bounded rationality, whereby choice behavior is regulated by cognitive and environmental constraints. Knight described features of risky choice that were to become key components of prospect theory (Kahneman and Tversky, 1979: the reference dependent valuation of outcomes, and the non-linear weighting of probabilities. Knight also discussed several biases in human decision making, and pointed to two systems of reasoning: one quick, intuitive but error prone, and a slower, more deliberate, rule-based system. A discussion of Knight's potential contribution to psychological decision theory emphasises the importance of a historical perspective on theory development, and the potential value of sourcing ideas from other disciplines or from earlier periods of time.

Orb-web and cob-web weaving spiders spin dragline silk fibers that are among the strongest materials known. Draglines are primarily composed of MaSp1 and MaSp2, two spidroins (spider fibrous proteins) expressed in the major ampullate (MA) silk glands. Prior genetic studies of dragline silk have focused mostly on determining the sequence of these spidroins, leaving other genetic aspects of silk synthesis largely uncharacterized. Here, we used deep sequencing to profile gene expression patterns in the Western black widow, Latrodectus hesperus. We sequenced millions of 3'-anchored "tags" of cDNAs derived either from MA glands or control tissue (cephalothorax) mRNAs, then associated the tags with genes by compiling a reference database from our newly constructed normalized L. hesperus cDNA library and published L. hesperus sequences. We were able to determine transcript abundance and alternative polyadenylation of each of three loci encoding MaSp1. The ratio of MaSp1:MaSp2 transcripts varied between individuals, but on average was similar to the estimated ratio of MaSp1:MaSp2 in dragline fibers. We also identified transcription of TuSp1 in MA glands, another spidroin family member that encodes the primary component of egg-sac silk, synthesized in tubuliform glands. In addition to the spidroin paralogs, we identified 30 genes that are more abundantly represented in MA glands than cephalothoraxes and represent new candidates for involvement in spider silk synthesis. Modulating expression rates of MaSp1 variants as well as MaSp2 and TuSp1 could lead to differences in mechanical properties of dragline fibers. Many of the newly identified candidate genes likely encode secreted proteins, suggesting they could be incorporated into dragline fibers or assist in protein processing and fiber assembly. Our results demonstrate previously unrecognized transcript complexity in spider silk glands.

2003-01-01

71 Ga nuclear magnetic resonance studies were carried out for liquid gallium embedded into porous glasses with different pore sizes and into artificial opals within the temperature range from about 320 K to complete confined gallium freezing. A general decrease in the Knight shift compared to the bulk melt depending on pore sizes was observed in contrast to theoretical predictions. Correlations between alterations in the Knight shift and pore sizes were established for particular pore geometry. It was also observed that confined geometry affects the temperature dependence of the Knight shift in liquid gallium

Impact of Lygus spp. (Hemiptera: Miridae) on damage, yield and quality of lesquerella (Physaria fendleri), a potential new oil-seed crop.

Science.gov (United States)

Naranjo, Steven E; Ellsworth, Peter C; Dierig, David A

2011-10-01

Lesquerella, Physaria fendleri (A. Gray) S. Watson, is a mustard native to the western United States and is currently being developed as a commercial source of valuable hydroxy fatty acids that can be used in a number of industrial applications, including biolubricants, biofuel additives, motor oils, resins, waxes, nylons, plastics, corrosion inhibitors, cosmetics, and coatings. The plant is cultivated as a winter-spring annual and in the desert southwest it harbors large populations of arthropods, several of which could be significant pests once production expands. Lygus spp. (Hemiptera: Miridae) are common in lesquerella and are known pests of a number of agronomic and horticultural crops where they feed primarily on reproductive tissues. A 4-yr replicated plot study was undertaken to evaluate the probable impact of Lygus spp. on production of this potential new crop. Plant damage and subsequent seed yield and quality were examined relative to variable and representative densities of Lygus spp. (0.3-4.9 insects per sweep net) resulting from variable frequency and timing of insecticide applications. Increasing damage to various fruiting structures (flowers [0.9-13.9%], buds [1.2-7.1%], and seed pods [19.4-42.5%]) was significantly associated with increasing pest abundance, particularly the abundance of nymphs, in all years. This damage, however, did not consistently translate into reductions in seed yield (481-1,336 kg/ha), individual seed weight (0.5-0.7 g per 1,000 seed), or seed oil content (21.8-30.4%), and pest abundance generally explained relatively little of the variation in crop yield and quality. Negative effects on yield were not sensitive to the timing of pest damage (early versus late season) but were more pronounced during years when potential yields were lower due to weed competition and other agronomic factors. Results suggest that if the crop is established and managed in a more optimal fashion, Lygus spp. may not significantly limit yield

High-performance marketing: an interview with Nike's Phil Knight. Interview by Geraldine E. Willigan.

Science.gov (United States)

Knight, P

1992-01-01

Nike's advertising slogans--"Bo Knows," "Just Do It," and "There Is No Finish Line"--have moved beyond advertising into popular expression. Its athletic footwear and clothing have become a piece of Americana. Its brand name is as well known around the world as IBM and Coke. Behind the slogans and the flashy TV commercials is the vision of its founder, chairman, and CEO, Phil Knight. Since forming the company in 1962, Knight has taken Nike from a small-time distributor of Japanese track shoes to the top of the athletic shoe and apparel market. But not without a stumble. Along the way, Knight discovered that technological innovation alone could not continue to drive growth. When sales stagnated in the mid-1980s, Knight and Nike learned several hard lessons on how to build brands and understand consumers, and they transformed their technology company into a marketing company whose product is its most important marketing tool. "Ultimately," says Knight, "we wanted Nike to be the world's best sports and fitness company. Once you say that, you have a focus. You don't end up making wing tips or sponsoring the next Rolling Stones world tour." To keep the company growing, Nike began splitting its brands into sub-brands. In tennis, Nike divided its shoes into Challenge Court--for younger, more active players--and Supreme Court--for older, more mature players. That approach brought the company to a broader range of consumers while preserving the customer base. And to create an emotional tie with the consumer, Nike started advertising on TV. "Sports is at the heart of American culture," Knight says. "You can't explain much in 60 seconds, but when you show Michael Jordan, you don't have to. It's that simple."

Quantifying secondary pest outbreaks in cotton and their monetary cost with causal-inference statistics.

Science.gov (United States)

Gross, Kevin; Rosenheim, Jay A

2011-10-01

Secondary pest outbreaks occur when the use of a pesticide to reduce densities of an unwanted target pest species triggers subsequent outbreaks of other pest species. Although secondary pest outbreaks are thought to be familiar in agriculture, their rigorous documentation is made difficult by the challenges of performing randomized experiments at suitable scales. Here, we quantify the frequency and monetary cost of secondary pest outbreaks elicited by early-season applications of broad-spectrum insecticides to control the plant bug Lygus spp. (primarily L. hesperus) in cotton grown in the San Joaquin Valley, California, USA. We do so by analyzing pest-control management practices for 969 cotton fields spanning nine years and 11 private ranches. Our analysis uses statistical methods to draw formal causal inferences from nonexperimental data that have become popular in public health and economics, but that are not yet widely known in ecology or agriculture. We find that, in fields that received an early-season broad-spectrum insecticide treatment for Lygus, 20.2% +/- 4.4% (mean +/- SE) of late-season pesticide costs were attributable to secondary pest outbreaks elicited by the early-season insecticide application for Lygus. In 2010 U.S. dollars, this equates to an additional $6.00 +/- $1.30 (mean +/- SE) per acre in management costs. To the extent that secondary pest outbreaks may be driven by eliminating pests' natural enemies, these figures place a lower bound on the monetary value of ecosystem services provided by native communities of arthropod predators and parasitoids in this agricultural system.

Emergent bipartiteness in a society of knights and knaves

International Nuclear Information System (INIS)

Del Genio, C I; Gross, T

2011-01-01

We propose a simple model of a social network based on the so-called knights-and-knaves puzzles. The model describes the formation of networks between two classes of agents where links are formed by agents introducing their neighbors to others of their own class. We show that if the proportion of knights and knaves is within a certain range, the network self-organizes to a perfectly bipartite state. However, if the excess of one of the two classes is greater than a threshold value, bipartiteness is not observed. We offer a detailed theoretical analysis of the behavior of the model, investigate its behavior in the thermodynamic limit and argue that it provides a simple example of a topology-driven model whose behavior is strongly reminiscent of first-order phase transitions far from equilibrium.

The transverse field μSR-signal from μ + implanted in a CeAs single crystal shows a splitting into two components, displaying a positive and a negative Knight shift, respectively which both scale reasonably well with the magnetic bulk susceptibility above 10 K. The orientation dependence of the frequency shifts, measured at 15 K, is fully accounted for by the demagnetization field, implying an isotropic Knight shift, consistent with the μ + residing at the only interstitial site of high (cubic) symmetry, i.e., at the position (1/4,1/4,1/4). The occurrence of a split signal remains unexplained

2006-02-01

In 1870, R&C moved to its second site on the corner of Lexington Avenue and 42nd Street. A newly constructed building designed by a specialist in ecclesiastical architecture became the home of a 200-bed children's hospital planned entirely by Dr. James Knight, founder of the hospital and its first Surgeon-in-Chief. Expansion of the facilities and of the professional staff, although needed and welcomed, brought new challenges, changes, and conflicts. The root of these was to lie in the complex character of James Knight with his dogmatic approach to patient care vs the open nature of his newly appointed assistant, Virgil Gibney, who was to become his successor and eventually the second Surgeon-in-Chief. How these two personalities worked together for 13 years, abruptly parted, and then after Knight's death, the reappearance of Gibney, is a fascinating story of the early development of the first orthopedic hospital in this country. It was a period after the Civil War described as the "Gilded Age," where not only the country, but the city, was going through its own challenges, changes and conflicts. Emerging was a new era for R&C introducing surgery, postgraduate medical education, and eventually, clinical and basic research.

2003-01-01

We have performed 11 B NMR measurements in 11 B enriched MgB 2 powder sample in the normal phase. The Knight shift was accurately determined by using the magic angle spinning technique. Results for 11 B and 27 Al Knight shifts (K) and relaxation rates (1/T 1 ) are also reported for AlB 2 . The data show a dramatic decrease of both K and 1/T 1 for 11 B in AlB 2 with respect to MgB 2 . We compare experimental results with ab initio calculated NMR relaxation rates and Knight shifts. The experimental values for 1/T 1 and K are in most cases in good agreement with the theoretical results. We show that the decrease of K and 1/T 1 for 11 B is consistent with a drastic drop of the density of states at the boron site in AlB 2 with respect to MgB 2

Absent yet Present: On the Paradoxical Nature of Characters in Nabokov’s The Real Life of Sebastian Knight

Directory of Open Access Journals (Sweden)

Irina Marchesini

2016-11-01

Full Text Available The present research is focused on the theme of absence, an area of inquiry that might seem dominant in the field of Nabokov Studies. The analysis, which concentrates in particular on the key figures of the novel The Real Life of Sebastian Knight (1941, notably the narrator V. and the poet Sebastian Knight, interprets the characters’ construction through the paradigm of absence. Arguably, the construction of characters in The Real Life of Sebastian Knight is paradoxical: absence constitutes their essence at a core level, as it often happens in the context of the self-conscious genre. Moreover, absence plays a key role in characters’ design, linking them to all Nabokovian novels. However, despite their innermost ‘flatness’, to use Edward M. Forster’s terminology, they still appear to be ‘round’, i.e. plausible, mimetic figures.

Abstract A non-autoclaved solid diet was used to evaluate the entomopathogenic fungus Beauveria bassiana (Balsamo) Vuillemin (Hypocreales: Clavicipitaceae) strain NI8 and the insect growth regulator novaluron (Diamond® 0.83EC insecticide) for control of the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae). The diet was composed of toasted wheat germ, ground lima bean meal, soy flour, yolk of chicken eggs, inhibitor, and agar. It was prepared in one step by blending the ingredients in boiling water. The diet was used to bioassay L. lineolaris from the second instar to the adult stage. Fourth and fifth instars and adults of L. lineolaris were more susceptible than second and third instars to infection by B. bassiana , whereas second, third, and fourth instars had higher mortality than fifth instars 10 days after exposure to novaluron. No effects on longevity were observed in adults treated with novaluron when compared with the control, but longevity was significantly different from that of adults exposed to B. bassiana . Adults of L. lineolaris were maintained for over a month without changing the diet. The non-autoclaved diet is semi-liquid before it cools, which facilitates the mechanics of diet packaging similar to food packaging or lepidopteran diet preparation. This solid artificial diet for Lygus bugs provides improved research capacity for studying the ecology and susceptibility of Lygus spp. to a number of different control agents, including beneficial organisms, insect pathogens, and insecticidal toxins being developed for transgenic technologies.

In this article, we present early case studies and summarized results from a subset of the 20 applications highlighting the impact of important architecture differences between the Xeon-Phi and traditional Xeon processors. We summarize the status of the applications and describe the greater optimization strategy that has formed.

Deployment of the OSIRIS EM-PIC code on the Intel Knights Landing architecture

Science.gov (United States)

Fonseca, Ricardo

2017-10-01

Electromagnetic particle-in-cell (EM-PIC) codes such as OSIRIS have found widespread use in modelling the highly nonlinear and kinetic processes that occur in several relevant plasma physics scenarios, ranging from astrophysical settings to high-intensity laser plasma interaction. Being computationally intensive, these codes require large scale HPC systems, and a continuous effort in adapting the algorithm to new hardware and computing paradigms. In this work, we report on our efforts on deploying the OSIRIS code on the new Intel Knights Landing (KNL) architecture. Unlike the previous generation (Knights Corner), these boards are standalone systems, and introduce several new features, include the new AVX-512 instructions and on-package MCDRAM. We will focus on the parallelization and vectorization strategies followed, as well as memory management, and present a detailed performance evaluation of code performance in comparison with the CPU code.

María Eugenia Mayer

2009-12-01

Full Text Available Don Quixote’s first adventure, the combat with the Basque, and his last one, in which he meets the Auditor, both deal with a «knight»/gentleman who is leaving for the West Indies. The opposite pole of the Manchego knight is the gentleman appointed to the Audience of New Spain, ca. 1600, during Lerma’s Privacy. This lawyer/auditor hears two «cases»: the «strange humor» of the Manchegan, as told by the priest who has found an anonymous manuscript; and the «unnexpected business» of his future son-in-law, who will accompany him to Mexico, heir to a title. The Oidor’s discreet proceedings contrast with Don Quixote’s open proclaims, thus serving as key to a bicostal (Spain/Indies reading of the

A Hard Day’s Knights: Movie Time Travel, the Middle Ages, and a New Millenium

Directory of Open Access Journals (Sweden)

John Engle

2012-10-01

Full Text Available This article addresses the cinematic treatment of the Middle Ages through an analysis of two recent mass-audience American films, Black Knight and Timeline, both of which feature time travel as a leading plot element. Providing context for this discussion is a brief analysis of other similar films, as well as remarks regarding Twain's Connecticut Yankee, Ruskin's The Stones of Venice, and The Idylls of the King by Tennyson. As in these other works, the films in question use certain popular stereotypes of the Middle Ages—endemic violence, rigid class distinctions, religious fanaticism, spiritual cohesion, etc.—as lens through which to view the contemporary world. In addition to their roles as comic or action entertainment vehicles, Black Knight indirectly addresses American individualism and a cutthroat modern corporate culture, whereas Timeline touches upon millennial anxiety, '90's ethnic cleansing, and the American misadventure in Iraq.

The Legacy of G. Wilson Knight

Directory of Open Access Journals (Sweden)

Raw Laurence

2017-06-01

Full Text Available G. Wilson Knight (1897-1985 was one of the most influential Shakespearean critics of the mid-twentieth century. This piece surveys his work from 1930 until the early 1980s. Much affected by the First World War, he developed a style of criticism based on Christian principles of respect for other people and belief in an all-powerful God. Many of his most famous pieces (in THE WHEEL OF FIRE, for instance argue for human insignificance in an indifferent universe. It is up to all of us as individuals to develop methods of coping with this world. Wilson Knight’s ideas gained particular currency during the Second World War, when Britain’s very future seemed at risk due to the threat of Nazi invasion. Although much derided for his use of transcendent language—especially by his contemporary F. R. Leavis—Wilson Knight’s ideas seem to have acquired new significance in a globalized world, where individuals fight to main their identity in a technology-driven environment.

Effect of electron-photon interaction on the knight shift

International Nuclear Information System (INIS)

Tripathi, G.S.; Misra, C.M.; Tripathi, P.; Misra, P.K.

1990-01-01

The effect of electron-phonon interaction is considered on the spin (K s ), orbital (K o ) and spin-orbit (K so ) contributions to the Knight shift. In case of K s , it is found that the modifications caused due to the magnetic field dependence of electron self-energy in the presence of electron-phonon interaction is cancelled by the electron-phonon mass enhancement. However, in the presence of both electron-electron and electron-phonon interactions, the exchange enhancement parameter α is modified to α(1+γ) -1 where γ is the electron-phonon mass enhancement parameter. The orbital and spin-orbital contributions are mainly modified through the changes in the one-electron energies and wave functions. (orig.)

Home-range size and overlap within an introduced population of the Cuban Knight Anole, Anolis equestris (Squamata: Iguanidae

Directory of Open Access Journals (Sweden)

Paul M. Richards

2011-07-01

Full Text Available Many studies have investigated the spatial relationships of terrestrial lizards, but arboreal species remain poorly studiedbecause they are difficult to observe. The conventional view of home-range size and overlap among territorial, polygynous species of lizards is that: (1 male home ranges are larger than those of females; (2 male home ranges usually encompass, or substantiallyoverlap, those of several females; and (3 male home-range overlap varies but often is minimal, but female home ranges frequently overlap extensively. However, the paucity of pertinent studies makes it difficult to generalize these patterns to arboreal lizards. Weinvestigated home-range size and overlap in the arboreal Knight Anole, Anolis equestris, and compared our findings to published home-range data for 15 other species of Anolis. Using radiotelemetry and mark-recapture/resight techniques, we analyzed the home rangesof individuals from an introduced population of Knight Anoles in Miami, Florida. The home ranges of both sexes substantially overlapped those of the same- and different-sex individuals. In addition, male and female home ranges did not differ significantly, an unusual observation among lizard species. If one compares both male and female home ranges to those of other Anolis species, Knight Anoles have significantly larger home ranges, except for two species for which statistical comparisons were not possible. Our results suggest that home ranges and sex-specific spatial arrangements of canopy lizards may differ from those of more terrestrial species.

Desiderio e scrittura in "The Real Life of Sebastian Knight" di Vladimir Nabokov

2014-12-01

This paper examines, from a psychoanalytic standpoint, the intersection between identity and writing in the novel The Real Life of Sebastian Knight (1941 by Vladimir Nabokov. In particular, in the wake of Freud and Lacan, the following contribution will take the notions of desire, signifier, and the process of sublimation involved in artistic creation as interpretative devices. The main focus of the analysis will be the relationship between the two half-brothers of the novel, V (the narrator and Sebastian. First, I will show that Sebastian Knight holds the role of the object of desire for the characters who have established a close relationship with him and, in particular, for V. Secondly, the paper will be devoted to the analysis of the trauma experienced by the characters because of Sebastian's death, with a particular focus on the narrator's mourning through writing (the fictional biography we read in the novel; in the end, I will give evidence of the so-called signifier’s fallacy, crucial episodes in which the narrator can experience an insight into the truth of desire. Because of the not negligible question of the fictional paternity of The Real Life and the equally essential matter of V’s ‘stylistic touch’, metaliterary aspects of the novel will also be part of the following reading of the text.

For a dominant contact interaction between nuclei and conduction electrons the relaxation rate is deduced. The extreme cases of degenerate and non-degenerate semiconductors are separately discussed. At strong degeneracy the product of the Knight shift and relaxation time gives the Korringa relation for metals. Measurements of the NMR spin-lattice relaxation times of 115 InSb and 115 InAs were made between 4.2 and 300 K for strongly degenerated samples. The different relaxation mechanisms are discussed and the experimental and theoretical results are compared. (author)

Full Text Available Conceived in the late thirties as “bold humanist response to Depression-era fears of runaway scientific advance and soulless industrialism” (Morrison 2012, 6, the superhero has flourished as one of the most resilient archetypes of American popular culture. This essay analyses the literary and cultural contaminations that have engendered an unprecedented revision of the paradigm since the 1980s. In particular, it will take into account three graphic novels by American cartoonist Frank Miller (1957 - , one of leading figures of the mainstream comics renaissance, whose ideas have indelibly influenced the artistic development of both medium and genre. The Dark Knight Returns (1986, The Dark Knight Strikes Again (2002 and Holy Terror (2011 constitute an ideal Batman trilogy that charts the character’s evolution as political counterpoint to the perceived crisis of American identity. In this regard, Reaganism and 9/11 are polarized as historical discontinuities triggering the need for a new kind of a criminal (superhero. It will be in fact demonstrated how the novels hybridise the latent generic links to hardboiled pulp novels (R. Chandler, D.

This fruitful contamination on the one hand “play[s] with reader assumptions about genre” (Baetens and Frey 2015, 46, while on the other hand deconstructs the ideological underpinnings of the archetype, as the moral dichotomy and the alienation of justice from the law.

Theory of the Knight Shift and Flux Quantization in Superconductors

1962-05-01

Consequences of a generalization of the theory of superconductivity that yields a finite Knight shift are presented. In this theory, by introducing an electron-electron interaction that is not spatially invariant, the pairing of electrons with varying total momentum is made possible. An expression for Xs (the spin susceptibility in the superconducting state) is derived. In general Xs is smaller than Xn, but is not necessarily zero. The precise magnitude of Xs will vary from sample to sample and will depend on the nonuniformity of the samples. There should be no marked size dependence and no marked dependence on the strength of the magnetic field; this is in accord with observation. The basic superconducting properties are retained, but there are modifications in the various electromagnetic and thermal properties since the electrons paired are not time sequences of this generalized theory on flux quantization arguments are presented.(auth)

HFI of {sup 13}O in Pt: anomalous Knight Shift

1996-04-01

The Knight Shift K and the spin relaxation time T{sub 1} for interstitial impurities implanted in metals are important clues to investigate the electronic structure of the metals. Because Pt has very low local electron density around the Fermi level for interstitial impurities, Pt is known as the unique implantation medium in which the implanted nuclei show small K and large T{sub 1}. The recent development of the technique of polarized radioactive nuclear beams widen the variety of probe nuclei. In the present paper, we have studied the hyperfine interactions of {sup 13}O(I{sup {pi}}=3/2{sup -}, T{sub 1/2}=8.6 ms) and {sup 12}N(I{sup {pi}}=1{sup +}, T{sub 1/2}=11.0 ms) implanted into polycrystalline Pt(fcc) by means of {beta}-NMR technique for the systematic study of the electric structures of interstitial impurities.

Vibration transmission through sheet webs of hobo spiders (Eratigena agrestis) and tangle webs of western black widow spiders (Latrodectus hesperus).

Science.gov (United States)

Vibert, Samantha; Scott, Catherine; Gries, Gerhard

2016-11-01

Web-building spiders construct their own vibratory signaling environments. Web architecture should affect signal design, and vice versa, such that vibratory signals are transmitted with a minimum of attenuation and degradation. However, the web is the medium through which a spider senses both vibratory signals from courting males and cues produced by captured prey. Moreover, webs function not only in vibration transmission, but also in defense from predators and the elements. These multiple functions may impose conflicting selection pressures on web design. We investigated vibration transmission efficiency and accuracy through two web types with contrasting architectures: sheet webs of Eratigena agrestis (Agelenidae) and tangle webs of Latrodectus hesperus (Theridiidae). We measured vibration transmission efficiencies by playing frequency sweeps through webs with a piezoelectric vibrator and a loudspeaker, recording the resulting web vibrations at several locations on each web using a laser Doppler vibrometer. Transmission efficiencies through both web types were highly variable, with within-web variation greater than among-web variation. There was little difference in transmission efficiencies of longitudinal and transverse vibrations. The inconsistent transmission of specific frequencies through webs suggests that parameters other than frequency are most important in allowing these spiders to distinguish between vibrations of prey and courting males.

von Willebrand factor, Jedi knight of the bloodstream.

Science.gov (United States)

Springer, Timothy A

2014-08-28

When blood vessels are cut, the forces in the bloodstream increase and change character. The dark side of these forces causes hemorrhage and death. However, von Willebrand factor (VWF), with help from our circulatory system and platelets, harnesses the same forces to form a hemostatic plug. Force and VWF function are so closely intertwined that, like members of the Jedi Order in the movie Star Wars who learn to use "the Force" to do good, VWF may be considered the Jedi knight of the bloodstream. The long length of VWF enables responsiveness to flow. The shape of VWF is predicted to alter from irregularly coiled to extended thread-like in the transition from shear to elongational flow at sites of hemostasis and thrombosis. Elongational force propagated through the length of VWF in its thread-like shape exposes its monomers for multimeric binding to platelets and subendothelium and likely also increases affinity of the A1 domain for platelets. Specialized domains concatenate and compact VWF during biosynthesis. A2 domain unfolding by hydrodynamic force enables postsecretion regulation of VWF length. Mutations in VWF in von Willebrand disease contribute to and are illuminated by VWF biology. I attempt to integrate classic studies on the physiology of hemostatic plug formation into modern molecular understanding, and point out what remains to be learned. © 2014 by The American Society of Hematology.

The Global Nested Air Quality Prediction Modeling System for Hg (GNAQPMS-Hg) is a global chemical transport model coupled Hg transport module to investigate the mercury pollution. In this study, we present our work of transplanting the GNAQPMS model on Intel Xeon Phi processor, Knights Landing (KNL) to accelerate the model. KNL is the second-generation product adopting Many Integrated Core Architecture (MIC) architecture. Compared with the first generation Knight Corner (KNC), KNL has more new hardware features, that it can be used as unique processor as well as coprocessor with other CPU. According to the Vtune tool, the high overhead modules in GNAQPMS model have been addressed, including CBMZ gas chemistry, advection and convection module, and wet deposition module. These high overhead modules were accelerated by optimizing code and using new techniques of KNL. The following optimized measures was done: 1) Changing the pure MPI parallel mode to hybrid parallel mode with MPI and OpenMP; 2.Vectorizing the code to using the 512-bit wide vector computation unit. 3. Reducing unnecessary memory access and calculation. 4. Reducing Thread Local Storage (TLS) for common variables with each OpenMP thread in CBMZ. 5. Changing the way of global communication from files writing and reading to MPI functions. After optimization, the performance of GNAQPMS is greatly increased both on CPU and KNL platform, the single-node test showed that optimized version has 2.6x speedup on two sockets CPU platform and 3.3x speedup on one socket KNL platform compared with the baseline version code, which means the KNL has 1.29x speedup when compared with 2 sockets CPU platform.

An 11 m thick subhorizontal beach deposit rests on steeply dipping Cretaceous bedrock. Sediments, ranging from a basal boulder bed to upper sands, are poorly sorted and negatively skewed, indicating pronounced winnowing of fine material. Impact features on quartz grain surfaces attest to high-energy turbulent environments, and are similar to those found on clasts from modern nearby beaches. The Haast River was source to some of the sand and gravel. Heavy minerals from the Dun Mountain Ophiolite Belt were transported 85 km by fluvial/glacial and longshore drift processes, necessitating caution when using apparent lateral separation of source material for estimating strike-slip displacement rates on the Alpine Fault. An optical luminescence age estimate of 123 ± 7 ka for Knights Point beach sands dates to the last interglacial (MIS 5e). A shore-platform altitude of 113 m a.s.l. requires tectonic uplift of the Australian plate of 0.86 mm/yr, an order of magnitude less than the nearby Pacific plate.

The Knights Landing (KNL) release of the Intel Many Integrated Core (MIC) Xeon Phi line of processors is a potential game changer for HEP computing. With 72 cores and deep vector registers, the KNL cards promise significant performance benefits for highly-parallel, compute-heavy applications. Cori, the newest supercomputer at the National Energy Research Scientific Computing Center (NERSC), was delivered to its users in two phases with the first phase online at the end of 2015 and the second phase now online at the end of 2016. Cori Phase 2 is based on the KNL architecture and contains over 9000 compute nodes with 96GB DDR4 memory. ATLAS simulation with the multithreaded Athena Framework (AthenaMT) is a good potential use-case for the KNL architecture and supercomputers like Cori. ATLAS simulation jobs have a high ratio of CPU computation to disk I/O and have been shown to scale well in multi-threading and across many nodes. In this paper we will give an overview of the ATLAS simulation application with details on its multi-threaded design. Then, we will present a performance analysis of the application on KNL devices and compare it to a traditional x86 platform to demonstrate the capabilities of the architecture and evaluate the benefits of utilizing KNL platforms like Cori for ATLAS production.

Deep Learning (DL) algorithms have become ubiquitous in data analytics. As a result, major computing vendors --- including NVIDIA, Intel, AMD and IBM --- have architectural road-maps influenced by DL workloads. Furthermore, several vendors have recently advertised new computing products as accelerating DL workloads. Unfortunately, it is difficult for data scientists to quantify the potential of these different products. This paper provides a performance and power analysis of important DL workloads on two major parallel architectures: NVIDIA DGX-1 (eight Pascal P100 GPUs interconnected with NVLink) and Intel Knights Landing (KNL) CPUs interconnected with Intel Omni-Path. Our evaluation consists of a cross section of convolutional neural net workloads: CifarNet, CaffeNet, AlexNet and GoogleNet topologies using the Cifar10 and ImageNet datasets. The workloads are vendor optimized for each architecture. GPUs provide the highest overall raw performance. Our analysis indicates that although GPUs provide the highest overall performance, the gap can close for some convolutional networks; and KNL can be competitive when considering performance/watt. Furthermore, NVLink is critical to GPU scaling.

Zheng, Huihuo; Knight, Christopher; Galli, Giulia; Govoni, Marco; Gygi, Francois

We present the optimization of electronic structure codes Qbox and WEST targeting the Intel®Xeon Phi™processor, codenamed Knights Landing (KNL). Qbox is an ab-initio molecular dynamics code based on plane wave density functional theory (DFT) and WEST is a post-DFT code for excited state calculations within many-body perturbation theory. Both Qbox and WEST employ highly scalable algorithms which enable accurate large-scale electronic structure calculations on leadership class supercomputer platforms beyond 100,000 cores, such as Mira and Theta at the Argonne Leadership Computing Facility. In this work, features of the KNL architecture (e.g. hierarchical memory) are explored to achieve higher performance in key algorithms of the Qbox and WEST codes and to develop a road-map for further development targeting next-generation computing architectures. In particular, the optimizations of the Qbox and WEST codes on the KNL platform will target efficient large-scale electronic structure calculations of nanostructured materials exhibiting complex structures and prediction of their electronic and thermal properties for use in solar and thermal energy conversion device.

Altered gene regulation and potential association with metabolic resistance development to imidacloprid in the tarnished plant bug, Lygus lineolaris.

Science.gov (United States)

Zhu, Yu Cheng; Luttrell, Randall

2015-01-01

Chemical spray on cotton is almost an exclusive method for controlling tarnished plant bug (TPB), Lygus lineolaris. Frequent use of imidacloprid is a concern for neonicotinoid resistance in this key pest. Information of how and why TPB becomes less susceptible to imidacloprid is essential for effective monitoring and managing resistance. Microarray analysis of 6688 genes in imidacloprid-selected TPB (Im1500FF) revealed 955 upregulated and 1277 downregulated (≥twofold) genes in Im1500FF, with 369 and 485 of them annotated. Five P450 and nine esterase genes were significantly upregulated, and only one esterase gene and no P450 genes were downregulated. Other upregulated genes include helicases, phosphodiesterases, ATPases and kinases. Pathway analyses identified 65 upregulated cDNAs that encode 51 different enzymes involved in 62 different pathways, including P450 and esterase genes for drug and xenobiotic metabolisms. Sixty-four downregulated cDNAs code only 17 enzymes that are associated with only 23 pathways mostly related to food digestion. This study demonstrated a significant change in gene expression related to metabolic processes in imidacloprid-selected TPB, resulting in overexpression of P450 and esterase genes for potential excess detoxification and cross/multiple resistance development. The identification of these and other enzyme genes establishes a foundation to explore the complicity of potential imidacloprid resistance in TPB. Published 2014.

The workloads are vendor-optimized for each architecture. Our analysis indicates that although GPUs provide the highest overall performance, the gap can close for some convolutional networks; and the KNL can be competitive in performance/watt. We find that NVLink facilitates scaling efficiency on GPUs. However, its importance is heavily dependent on neural network architecture. Furthermore, for weak-scaling --- sometimes encouraged by restricted GPU memory --- NVLink is less important.

Lygus pratensis (L.) is an important cotton pest in China, especially in the northwest region. Nymphs and adults cause serious quality and yield losses. However, the genetic structure and geographic distribution of L. pratensis is not well known. We analyzed genetic diversity, geographical structure, gene flow, and population dynamics of L. pratensis in northwest China using mitochondrial and nuclear sequence datasets to study phylogeographical patterns and demographic history. L. pratensis (n = 286) were collected at sites across an area spanning 2,180,000 km2, including the Xinjiang and Gansu-Ningxia regions. Populations in the two regions could be distinguished based on mitochondrial criteria but the overall genetic structure was weak. The nuclear dataset revealed a lack of diagnostic genetic structure across sample areas. Phylogenetic analysis indicated a lack of population level monophyly that may have been caused by incomplete lineage sorting. The Mantel test showed a significant correlation between genetic and geographic distances among the populations based on the mtDNA data. However the nuclear dataset did not show significant correlation. A high level of gene flow among populations was indicated by migration analysis; human activities may have also facilitated insect movement. The availability of irrigation water and ample cotton hosts makes the Xinjiang region well suited for L. pratensis reproduction. Bayesian skyline plot analysis, star-shaped network, and neutrality tests all indicated that L. pratensis has experienced recent population expansion. Climatic changes and extensive areas occupied by host plants have led to population expansion of L. pratensis. In conclusion, the present distribution and phylogeographic pattern of L. pratensis was influenced by climate, human activities, and availability of plant hosts.

There are many potential issues associated with deploying the Intel Xeon Phi™ (code named Knights Landing [KNL]) manycore processor in a large-scale supercomputer. One in particular is the ability to fully utilize the high-speed communications network, given that the serial performance of a Xeon Phi TM core is a fraction of a Xeon®core. In this paper, we take a look at the trade-offs associated with allocating enough cores to fully utilize the Aries high-speed network versus cores dedicated to computation, e.g., the trade-off between MPI and OpenMP. In addition, we evaluate new features of Cray MPI in support of KNL, such as internode optimizations. We also evaluate one-sided programming models such as Unified Parallel C. We quantify the impact of the above trade-offs and features using a suite of National Energy Research Scientific Computing Center applications.

We profile and optimize calculations performed with the BerkeleyGW code on the Xeon-Phi architecture. BerkeleyGW depends both on hand-tuned critical kernels as well as on BLAS and FFT libraries. We describe the optimization process and performance improvements achieved. We discuss a layered parallelization strategy to take advantage of vector, thread and node-level parallelism. We discuss locality changes (including the consequence of the lack of L3 cache) and effective use of the on-package high-bandwidth memory. We show preliminary results on Knights-Landing including a roofline study of code performance before and after a number of optimizations. We find that the GW method is particularly well-suited for many-core architectures due to the ability to exploit a large amount of parallelism over plane-wave components, band-pairs, and frequencies.

Probing behavior of Lygus lineolaris (Palisot de Beauvois) has previously been characterized with electropenetrography (EPG). Cell rupturing (CR) and ingestion (I) EPG waveforms were identified as the two main stylet-probing behaviors by adult L. lineolaris. However, characterization and identification of EPG waveforms are not complete until specific events of a particular waveform are correlated to insect probing. With the use of EPG, histology, microscopy, and chemical analysis, probing behavior of L. lineolaris on pin-head cotton squares was studied. Occurrences of waveforms CR and I were artificially terminated during the EPG recording. Histological samples of probed cotton squares were prepared and analyzed to correlate specific types and occurrences of feeding damage location and plant responses to insect feeding. Both CR and I occurred in the staminal column of the cotton square. Cell rupturing events elicited the production of dark-red deposits seen in histological staining that were demonstrated via chemical analysis to contain condensed tannins. We hypothesize that wounding and saliva secreted during CR triggered release of tannins, because tannin production was positively correlated with the number of probes with single CR events performed by L. lineolaris. Degraded plant tissue and tannins were removed from the staminal column during occurrence of waveform I. These results conclude the process of defining CR and I as probing waveforms performed by L. lineolaris on pin-head cotton squares. These biological definitions will now allow EPG to be used to quantitatively compare L. lineolaris feeding among different plant treatments, with the goal of improving pest management tactics against this pest.

A 17 O NMR study has been performed on a 17 O enriched powder sample of (Bi,Pb) 2 Sr 2 Ca 2 Cu 3 O y , also called n=3 phase (with Tc=110K) which belongs to the Bi-based superconductors family (Bi,Pb) 2 Sr 2 Ca n-1 Cu n O 2n+4 . The n=3 compound which contains in its unit cell two types of CuO 2 planes (labelled type I and II), is compared to the n=2 compound where only one type of CuO 2 planes (type I) is present. 17 O Knight shift measurements versus temperature, in the normal phase, have allowed us to evidence the distinct behaviours of the two types of planes present in the n=3 compound. The results are consistent with the existence of stronger electron correlations, or smaller charge carrier density in the type II planes. 14 refs., 3 figs

The kudzu bug, Megacopta cribraria (F.), is an urban nuisance and significant agricultural pest. The median lethal concentrations of three strains of Beauveria bassiana (Balsamo), including the Mississippi Delta native strain (NI8) isolated from Lygus lineolaris (Palisot de Beauvois), the commercial strain BotaniGard(®) (GHA) (Victor, NY, USA), and the B. bassiana strain isolated from M. cribraria (KUDSC), were estimated on kudzu bug adults. A technique developed to evaluate B. bassiana against L. lineolaris was used. Younger adults (eight days after collection) were treated with NI8 and GHA and older adult (50 days after collection) were treated with NI8, GHA and KUDSC. Higher concentrations (n × 10⁶, n × 10⁷) of NI8 and GHA caused kudzu bug mortality two days after treatment in younger adults and similar concentrations of NI8, GHA, and KUDSC caused mortality one day after treatment in older adults. Lower concentrations (n × 10⁴, n × 10⁵) were not significantly different in mortality between strains. LS50 values of the KUDSC were significantly lower than NI8 and GHA values in older adults. This is the first available information on median lethal concentration of B. bassiana on kudzu bug adults bioassayed on artificial diet. It was determined that B. bassiana (KUDSC and NI8) are highly effective for young adults at very low doses (LC50 1.98-4.98 viable spores per mm²).

Chromosome mapping of dragline silk genes in the genomes of widow spiders (Araneae, Theridiidae.

Directory of Open Access Journals (Sweden)

Yonghui Zhao

Full Text Available With its incredible strength and toughness, spider dragline silk is widely lauded for its impressive material properties. Dragline silk is composed of two structural proteins, MaSp1 and MaSp2, which are encoded by members of the spidroin gene family. While previous studies have characterized the genes that encode the constituent proteins of spider silks, nothing is known about the physical location of these genes. We determined karyotypes and sex chromosome organization for the widow spiders, Latrodectus hesperus and L. geometricus (Araneae, Theridiidae. We then used fluorescence in situ hybridization to map the genomic locations of the genes for the silk proteins that compose the remarkable spider dragline. These genes included three loci for the MaSp1 protein and the single locus for the MaSp2 protein. In addition, we mapped a MaSp1 pseudogene. All the MaSp1 gene copies and pseudogene localized to a single chromosomal region while MaSp2 was located on a different chromosome of L. hesperus. Using probes derived from L. hesperus, we comparatively mapped all three MaSp1 loci to a single region of a L. geometricus chromosome. As with L. hesperus, MaSp2 was found on a separate L. geometricus chromosome, thus again unlinked to the MaSp1 loci. These results indicate orthology of the corresponding chromosomal regions in the two widow genomes. Moreover, the occurrence of multiple MaSp1 loci in a conserved gene cluster across species suggests that MaSp1 proliferated by tandem duplication in a common ancestor of L. geometricus and L. hesperus. Unequal crossover events during recombination could have given rise to the gene copies and could also maintain sequence similarity among gene copies over time. Further comparative mapping with taxa of increasing divergence from Latrodectus will pinpoint when the MaSp1 duplication events occurred and the phylogenetic distribution of silk gene linkage patterns.

Motivations and Implications of Community Service Provision by La Familia Michoacána / Knights Templar and other Mexican Drug Cartels

Full Text Available Research demonstrates that service provision by violent organizations can be an effective strategy for coercing the local community to accept and conceal a group’s violent activities, and for creating loyalty to these groups. This has been most frequently explored among political organizations such as terrorist groups, with organizations like Hezbollah and Hamas very visibly engaged in providing social welfare in addition to their violent activities. Recent reports indicate that criminal organizations in Mexico also are involved in instances of public service provision in local communities. This article explores the extent to which drug cartels operating in Mexico are involved in public service provision to members of communities where they operate, and considers possible motivations and implications for public service provision by these criminal organizations, with specific attention to the organization La Familia Michoacána/ Knights Templar. The article also gives attention to the consequences to citizenship and government of service provision by violent nonstate actors, and the ways such service provision may disrupt the social contract between the citizen and the state.

Animal venoms attract enormous interest given their potential for pharmacological discovery and understanding the evolution of natural chemistries. Next-generation transcriptomics and proteomics provide unparalleled, but underexploited, capabilities for venom characterization. We combined multi-tissue RNA-Seq with mass spectrometry and bioinformatic analyses to determine venom gland specific transcripts and venom proteins from the Western black widow spider (Latrodectus hesperus) and investigated their evolution. We estimated expression of 97,217 L. hesperus transcripts in venom glands relative to silk and cephalothorax tissues. We identified 695 venom gland specific transcripts (VSTs), many of which BLAST and GO term analyses indicate may function as toxins or their delivery agents. ~38% of VSTs had BLAST hits, including latrotoxins, inhibitor cystine knot toxins, CRISPs, hyaluronidases, chitinase, and proteases, and 59% of VSTs had predicted protein domains. Latrotoxins are venom toxins that cause massive neurotransmitter release from vertebrate or invertebrate neurons. We discovered ≥ 20 divergent latrotoxin paralogs expressed in L. hesperus venom glands, significantly increasing this biomedically important family. Mass spectrometry of L. hesperus venom identified 49 proteins from VSTs, 24 of which BLAST to toxins. Phylogenetic analyses showed venom gland specific gene family expansions and shifts in tissue expression. Quantitative expression analyses comparing multiple tissues are necessary to identify venom gland specific transcripts. We present a black widow venom specific exome that uncovers a trove of diverse toxins and associated proteins, suggesting a dynamic evolutionary history. This justifies a reevaluation of the functional activities of black widow venom in light of its emerging complexity.

To describe the development, test-retest reliability, internal consistency, and convergent validity of the McKnight Risk Factor Survey-III (MRFS-III). The MRFS-III was designed to assess a number of potential risk and protective factors for the development of disordered eating in preadolescent and adolescent girls. Several versions of the MRFS were pilot tested before the MRFS-III was administered to a sample of 651 4th through 12th- grade girls to establish its psychometric properties. Most of the test-retest reliability coefficients of individual items on the MRFS-III were r > .40. Alpha coefficients for each risk and protective factor domain on the MRFS-III were also computed. The majority of these coefficients were r > .60. High convergent validity coefficients were obtained for specific items on the MRFS-III and measures of self-esteem (Rosenberg Self-Esteem Scale) and weight concerns (Weight Concerns Scale). The test-retest reliability, internal consistency, and convergent validity of the MRFS-III suggest that it is a useful new instrument to assess potential risk and protective factors for the development of disordered eating in preadolescent and adolescent girls.

An abnormally large muon Knight shift has been observed in the weakly diamagnetic semimetal antimony (Sb). An attempt to observe the Knight shift in a single crystal sample of SbBi (15 at.%) produced no detectable effect. This stimulated the authors' curiosity and they tried to measure the muon Knight shift in the same SbBi (15 at.%) sample with their stroboscopic high precision apparatus. The measured Knight shift and depolarization rate as a function of temperature and crystal orientation are displayed. The most striking features are the large and temperature-dependent anisotropy in the Knight shift and its change of sign around 80 K. The depolarization rate shows an equally strong temperature dependence both in the average rate and in its anisotropic behaviour. (Auth.)

America's First Carl Sagan: Ormsby MacKnight Mitchel, Pre-Civil War Astronomer and Lecturer on the Cosmos

Science.gov (United States)

Osterbrock, D. E.

2002-12-01

In the years before television, videos, radio. movies, or even loudspeakers, Ormsby MacKnight Mitchel (1809-1862) was the best-known popularizer of astronomy and the scientific study of the universe in nineteenth-century America. Each winter he traveled the country by railroad, steamer, and stagecoach, speaking to large paying crowds in principal cities from Boston, New York, and Philadelphia through Cincinnati to New Orleans on the cosmos and our place in it, with special attention to possible inhabitants of planers orbiting other stars. Mitchel had much the same attraction as Sagan did in our time, and awakened many people's interest in astronomy through the human angle, as Carl did. His argument was simple, and according to Frank Triplett goes back thousands of years: other stars are suns, our sun has planets with people on one of them, why should not other stars also have populated planets? But first Mitchel, like Sagan, always explained clearly the discoveries of astronomy that fleshed out this argument with facts. He emphasized the ``clockwork universe", governed by gravity, that Newton, Herschel, and Laplace had investigated and found to be stable. There were many other similarities between these two great popularizers. Mitchel's base was the Cincinnati Observatory, which he had founded, raising the funds for it himself in small contributions from hundreds of ``members", which he publicised as far more democratic than support from European kings and lords. He went abroad to get a telescope, and finally found his ``Great [12-inch] Refractor" in Munich, with help from John Quincy Adams, Astronomer Royal George Biddle Airy, and Paris Observatory Director Fracois Arago, in spite of a rebuff by President John Tyler. These episodes have similarities in Sagan's lobbying NASA for close-up images of Mars. Views of other American professional astronomers on life on other worlds will also be described briefly, from Denison Olmsted, Elias Loomis, Charles A. Young (who

Varble, J

2007-01-01

Cane-based Celotex(trademark) has been used extensively in various DOE packages as a thermal insulator and impact absorber. Cane-based Celotex(trademark) for the 9975 was manufactured by Knight-Celotex Fiberboard at their Marrero Plant in Louisiana. However, Knight-Celotex Fiberboard shut down their Marrero Plant in early 2007 due to impacts from hurricane Katrina and other economic factors. Therefore, cane-based Celotex(trademark) is no longer available for use in the manufacture of new 9975 packages. Knight-Celotex Fiberboard has Celotex(trademark) manufacturing plants in Danville, VA and Sunbury, PA that use softwood and hardwood, respectively, as a raw material in the manufacturing of Celotex(trademark). The purpose of this White Paper is to demonstrate that softwood-based Celotex(trademark) from the Knight-Celotex Danville Plant has performance equivalent to cane-based Celotex(trademark) from the Knight-Celotex Marrero Plant for transportation in a 9975 package

The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), has taken on added importance as a pest of cotton in the Cotton Belt after successful eradication efforts for the boll weevil (Anthonomus grandis grandis Boheman). Because the Southern Blacklands region of Central Texas is in advanced stages of boll weevil eradication, blooming weeds and selected row crops were sampled during a 3-yr study to determine lygus species composition and associated temporal host plants. L. lineolaris was the sole lygus species in the region. Thirteen previously unreported host plants were identified for L. lineolaris, of which 69% supported reproduction. Rapistrum rugosum L. Allioni and Ratibida columnifera (Nuttall) Wooton and Standley were primary weed hosts during the early season (17 March to 31 May). Conyza canadensis L. Cronquist variety canadensis and Ambrosia trifida L. were primary weed hosts during the midseason (1 June to 14 August) and late-season (15 August to 30 November), respectively. Sisymbrium irio L. and Lamium amplexicaule L. sustained L. lineolaris populations during the overwintering period (1 December to 16 March). The proportion of females and numbers of nymphs found in R. rugosum, C. canadensis, A. trifida, and S. irio suggests these weeds supported reproductive adults during the early, mid-, and late season and overwintering period, respectively. Medicago sativa L. was the leading crop host for L. lineolaris; Glycine max L. Merrill did not yield L. lineolaris. Few L. lineolaris were collected in Gossypium hirsutum L. These results provide a more comprehensive assessment of host plants contributing to L. lineolaris populations in central Texas.

Financial Intelligence for Entrepreneurs: What You Really Need to Know about the Numbers, (Boston MA: Harvard Business Press, 2008. 285 pp. ISBN 978-1-4221-1915-0. From “The art of finance (and why it matters” (Part One through “Creating a financially intelligent company” (Part Eight, Financial Intelligence for Entrepreneurs is an engaging explanation and appreciation of financial statements and financial ratios. Short, easily digested chapters; just-in-time boxes to introduce terminology; easy, direct, in-text calculations from bare-bones, hypothetical financial statements to illustrate concepts; a 44-page appendix of crafted exercises on the income statement, balance sheet, cash-flow statement, and financial ratios from two public companies for deeper understanding; a detailed 19-page index for quick, after-you’ve-read-it navigation – all make for an efficient learning opportunity for readers who want a painless way to know about the numbers used in the world of business. Two quantitative literacy principles emerge as themes. The first is the “art of finance” (social construction: that is, the numbers are not totally objective; to varying extents, they reflect decisions, assumptions, and estimates in the accounting. The second is that ratios provide a window into the story that financial statements are able to tell. Written for entrepreneurs and company owners, the book ends with OBM (open-book management—a management philosophy based on financial literacy. The vision of this book is businesses in which all employees are financially literate and managers and owners are financially intelligent.

Accelerating 3D Elastic Wave Equations on Knights Landing based Intel Xeon Phi processors

Science.gov (United States)

Sourouri, Mohammed; Birger Raknes, Espen

2017-04-01

In advanced imaging methods like reverse-time migration (RTM) and full waveform inversion (FWI) the elastic wave equation (EWE) is numerically solved many times to create the seismic image or the elastic parameter model update. Thus, it is essential to optimize the solution time for solving the EWE as this will have a major impact on the total computational cost in running RTM or FWI. From a computational point of view applications implementing EWEs are associated with two major challenges. The first challenge is the amount of memory-bound computations involved, while the second challenge is the execution of such computations over very large datasets. So far, multi-core processors have not been able to tackle these two challenges, which eventually led to the adoption of accelerators such as Graphics Processing Units (GPUs). Compared to conventional CPUs, GPUs are densely populated with many floating-point units and fast memory, a type of architecture that has proven to map well to many scientific computations. Despite its architectural advantages, full-scale adoption of accelerators has yet to materialize. First, accelerators require a significant programming effort imposed by programming models such as CUDA or OpenCL. Second, accelerators come with a limited amount of memory, which also require explicit data transfers between the CPU and the accelerator over the slow PCI bus. The second generation of the Xeon Phi processor based on the Knights Landing (KNL) architecture, promises the computational capabilities of an accelerator but require the same programming effort as traditional multi-core processors. The high computational performance is realized through many integrated cores (number of cores and tiles and memory varies with the model) organized in tiles that are connected via a 2D mesh based interconnect. In contrary to accelerators, KNL is a self-hosted system, meaning explicit data transfers over the PCI bus are no longer required. However, like most

We have expanded the field of "DNA computers" to RNA and present a general approach for the solution of satisfiability problems. As an example, we consider a variant of the "Knight problem," which asks generally what configurations of knights can one place on an n x n chess board such that no knight is attacking any other knight on the board. Using specific ribonuclease digestion to manipulate strands of a 10-bit binary RNA library, we developed a molecular algorithm and applied it to a 3 x 3 chessboard as a 9-bit instance of this problem. Here, the nine spaces on the board correspond to nine "bits" or placeholders in a combinatorial RNA library. We recovered a set of "winning" molecules that describe solutions to this problem.

Dilute Al and V NMR in α-Ti

1992-01-01

We report a nuclear-magnetic-resonance investigation of four titanium alloys: Ti--1 at. % V, Ti--2 at. % V, Ti--1 at. % Al, and Ti--2 at. % Al. Interpretation of the experimental 51 V and 27 Al absorption curves was accomplished largely by comparison with computer-simulated curves. Since the latter include the effects of nuclear-quadrupole and anisotropic Knight-shift interactions, dipolar broadening, and inhomogeneous Knight shift for the V and Al solute nuclei, the comparison yields experimental values for the electric-field gradient, axially symmetric anistropic Knight shift, and isotropic Knight shift, from which we attempt to deduce the local charge distribution at the V or Al atoms in the hcp α-Ti matrix. We find that the localized states on an Al impurity exhibit very little of the character of the host Ti atomic structure. There is no orbital contribution to the Knight shift and the s conduction-electron density at Al sites is small. On the other hand, when vanadium is present as a dilute solute in the Ti lattice, only minor changes in its Knight shift are found. There is a large orbital-shift contribution, and the V nuclear absorption exhibits much the same character as in pure metallic V; there is, however, clear evidence of the V charge distribution assuming the hexagonal symmetry of the Ti lattice. The measured temperature dependences of the anisotropic Knight shift and electric-field-gradient values at V solute sites in Ti are also discussed. On partitioning the field gradient we find that the contribution from local non-s electrons is about two to five times larger in magnitude than the Ti-lattice ion value, a strong indication that the electronic structure near V (but not Al) resembles that of the matrix Ti

NMR measurements were carried out on pristine ZrNCl and Li x ZrNCl. From the 15 N-Knight shift study, the isotropic Knight shift, the traceless chemical (orbital) shift tensor and the traceless Knight shift tensor were determined as K iso = -71 ppm, (σ 1 , σ 2 , σ 3 ) = (-55, -55, 110) ppm and (K 1 , K 2 , K 3 ) = (48, 48, -96) ppm, respectively. In the superconducting state, the fractional change of the 15 N NMR shift for H-parallel ab was observed, evidencing that the pairing symmetry is a spin-singlet state.

 Student-run free clinics (SRFCs) are a recent popular addition to medical school education, and a subset of studies has looked at the influence of SRFC volunteering on the medical student's career development. The majority of the research done in this area has focused on understanding if these SRFCs produce physicians who are more likely to practice medicine in underserved communities, caring for the uninsured. The remainder of the research has investigated if volunteering in an SRFC influences the specialty choice of medical school students. The results of these specialty choice studies give no definitive answer as to whether medical students chose primary or specialty care residencies as a result of their SRFC experience. Keeping Neighbors in Good Health through Service (KNIGHTS) is the SRFC of the University of Central Florida College of Medicine (UCF COM). Both primary and specialty care is offered at the clinic. It is the goal of this study to determine if volunteering in the KNIGHTS SRFC influences UCF COM medical students to choose primary care, thereby helping to meet the rising need for primary care physicians in the United States.  A survey was distributed to first, second, and third-year medical students at the UCF COM to collect data on demographics, prior volunteering experience, and specialty choice for residency. Responses were then combined with records of volunteer hours from the KNIGHTS Clinic and analyzed for correlations. We analyzed the frequency and Pearson's chi-squared values. A p value of less than 0.05 was considered statistically significant.  Our survey had a total response rate of 39.8%. We found that neither the act of becoming a KNIGHTS Clinic volunteer nor the hours volunteered at the KNIGHTS Clinic influenced the UCF COM student's choice to enter a primary care specialty (p = NS). Additionally, prior volunteering/clinical experience or the gender of the medical school student did not influence a student's choice to volunteer at

The spin relaxation time T 1 for short-lived beta emitters 13 O and 23 Mg implanted in Pt have been measured for the first time; T 1 T( 13 O)=2.90±0.65 Ks and T 1 T( 23 Mg)=1665±140 Ks. The Knight shift for 13 O in Pt was measured at 300 K to be K( 13 O)=+(4.23±0.14).10 -3 . In the case of 13 O, the Knight shift is unusually large and the relaxation time is unusually fast compared with other interstitial impurities in Pt. A KKR band-structure calculation reproduces the present large Knight shift fairly well. (orig.)

The {sup 23}Na Knight shift of NMR line which is highly correlated with the electron spin susceptibility and density of states at the Fermi level was studied for the sodium loaded opal. The measurements were carried out within a temperature range from 100 to 400 K for solid and melted confined sodium nanoparticles. The NMR line below 305 K was a singlet with the Knight shift reduced compared to that in bulk. Above this temperature the NMR line split reproducibly into two components with opposite trends in the Knight shift temperature dependences which evidenced a nanoconfinement-induced transformation and heterogeneity in the electron system. The findings were suggested to be related to changes in the topology of the Fermi surface.

{sup 103}Rh nuclear magnetic resonance (NMR) measurements have been performed in the superconductor Rh{sub 17}S{sub 15} with the transition temperature T{sub C}=5.4 K. The observed {sup 103}Rh-NMR spectrum shows an asymmetric shape with several peaks, reflecting the local symmetry around each Rh site. We have identified the observed NMR lines corresponding to four different Rh sites and obtained the temperature (T) dependence of the Knight shift of 24m site. The isotropic part of the Knight shift K{sub iso} decreases with decreasing T, indicating the existence of the electron correlation in Rh{sub 17}S{sub 15}. In the superconducting state, the resonance lines shift to higher frequencies owing to a decrease of the spin part of the Knight shift with negative hyperfine coupling.

The number of primary care physicians in the United States continues to lag behind the number of uninsured people. There has been a growing demand for medical students to improve their self-efficacy, comfortableness, attitude, and interest in working with the underserved and in primary care. This study aims to discern whether volunteering at a student-run, free healthcare clinic has a positive impact on these five variables of interest or not. A 95-item survey was distributed through Qualtrics Survey Software (Qualtrics, Provo, UT, USA) to medical students from the Class of 2018 and Class of 2019 at the University of Central Florida College of Medicine. They were recruited via emails, Facebook, and in-classroom announcements. Mean responses on a Likert-like scale to different survey items were collected and compared between two study cohorts: Keeping Neighbors In Good Health Through Service (KNIGHTS) Clinic volunteers and non-volunteers. Results from 128 students showed no significant differences in the means between the two cohorts (p-values were not significant). When volunteers were asked the survey item, "KNIGHTS Clinic positively influenced my attitude towards working with underserved patients," 62% strongly agreed, 26% agreed, 10% were neutral, and 2% disagreed. Based on the results, volunteering at KNIGHTS Clinic may not have a positive impact on the five variables of interest. However, the lack of significance may also be due to certain limitations of this study addressed elsewhere in this paper. With the majority of KNIGHTS Clinic volunteers agreeing that "KNIGHTS Clinic positively influenced […their] attitude towards working with underserved patients," there may be a positive impact of volunteering on volunteers' attitude towards working with the underserved.

Dunn, Amara R; Smart, Christine D

Using host resistance is an important strategy for managing pepper root and crown rot caused by Phytophthora capsici. An isolate of P. capsici constitutively expressing a gene for green fluorescent protein was used to investigate pathogen interactions with roots, crowns, and stems of Phytophthora-susceptible bell pepper 'Red Knight', Phytophthora-resistant bell pepper 'Paladin', and Phytophthora-resistant landrace Criollos de Morelos 334 (CM-334). In this study, the same number of zoospores attached to and germinated on roots of all cultivars 30 and 120 min postinoculation (pi), respectively. At 3 days pi, significantly more secondary roots had necrotic lesions on Red Knight than on Paladin and CM-334 plants. By 4 days pi, necrotic lesions had formed on the taproot of Red Knight but not Paladin or CM-334 plants. Although hyphae were visible in the crowns and stems of all Red Knight plants observed at 4 days pi, hyphae were observed in crowns of only a few Paladin and in no CM-334 plants, and never in stems of either resistant cultivar at 4 days pi. These results improve our understanding of how P. capsici infects plants and may contribute to the use of resistant pepper cultivars for disease management and the development of new cultivars.

"There is no greater or more immediate challenge than that posed by climate change," said Sir Richard Branson, chairman of the Virgin group, via video-link at the 59th International Astronautical Congress (IAC) held in Glasgow in the UK at the end of September. That grand statement may seem like a lot of hot air for the entrepreneur best known for his attempt to circumnavigate the globe by balloon. But Branson went on to reveal that Virgin Galactic, which aims to fly passengers 100 km into space for 200 000 per trip, will also provide room on its craft for a series of scientific experiments to study the Earth's atmosphere.

Viajando con Don Quijote en el siglo XXI

Full Text Available Don Quixote has ridden with us for a long time now, and as if his fight against windmills were not enough, Don Quixote still has many more difficult situations to combat in the present times. Will the Knight of the Sad Figure accomplish this new deed? It is our challenge to find an answer to this inquiry. For this purpose, the author of this essay inserts the Knight of the Sad Figure in XXI century society. The author transforms the values, costumes and points of view of the times of the literary piece and establishes a series of relationships between the literary text, the main character and several current daily life situations. Don Quixote will certainly continue his fight against all the conditions we encounter nowadays. There is no doubt, then, that this knight still lives among us.

Sweep-twist adaptive rotor blade : final project report.

Energy Technology Data Exchange (ETDEWEB)

Ashwill, Thomas D.

2010-02-01

Knight & Carver was contracted by Sandia National Laboratories to develop a Sweep Twist Adaptive Rotor (STAR) blade that reduced operating loads, thereby allowing a larger, more productive rotor. The blade design used outer blade sweep to create twist coupling without angled fiber. Knight & Carver successfully designed, fabricated, tested and evaluated STAR prototype blades. Through laboratory and field tests, Knight & Carver showed the STAR blade met the engineering design criteria and economic goals for the program. A STAR prototype was successfully tested in Tehachapi during 2008 and a large data set was collected to support engineering and commercial development of the technology. This report documents the methodology used to develop the STAR blade design and reviews the approach used for laboratory and field testing. The effort demonstrated that STAR technology can provide significantly greater energy capture without higher operating loads on the turbine.

Bräuner, Elvira; Andersen, Zorana Jovanovic; Frederiksen, Marie

2016-01-01

Polychlorinated-biphenyls (PCBs) were introduced in the late 1920s and used until the 1970s when they were banned in most countries due to evidence of environmental build-up and possible adverse health effects. However they still persist in the environment, indoors and in humans. Indoor air...... in contaminated buildings may confer airborne exposure markedly above background regional PCB levels. To date, no epidemiological studies have assessed the health effects from exposure to semi-volatile PCBs in the indoor environment. Indoor air PCBs are generally less chlorinated than PCBs that are absorbed via...... the diet, or via past occupational exposure; therefore their health effects require separate risk assessment. Two separate cohorts of individuals who have either attended schools (n = 66,769; 26% exposed) or lived in apartment buildings (n = 37,185; 19% exposed), where indoor air PCB concentrations have...

ERP to chess stimuli reveal expert-novice differences in the amplitudes of N2 and P3 components.

Science.gov (United States)

Wright, Michael J; Gobet, Fernand; Chassy, Philippe; Ramchandani, Payal Nanik

2013-10-01

ERP experiments were conducted to analyze the underlying neural events when chess players make simple judgments of a board position. Fourteen expert players and 14 age-matched novices viewed, for each of four tasks, 128 unique positions on a mini (4 × 4) chess board each presented for 0.5 s. The tasks were to respond: (a) if white king was in check, (b) if black knight was present, (c) if white king was not in check, and (d) if no black knight was present. Experts showed an enhanced N2 with check targets and a larger P3 with knight targets, relative to novices. Expert-novice differences in posterior N2 began as early as 240 ms on check-related searches. Results were consistent with the view that prolonged N2 components reflect matching of current perceptual input to memory, and thus are sensitive to experts' superior pattern recognition and memory retrieval of chunks.

DEMONSTRATION OF EQUIVALENCY OF CANE AND SOFTWOOD BASED CELOTEX FOR MODEL 9975 SHIPPING PACKAGES

International Nuclear Information System (INIS)

Watkins, R; Jason Varble, J

2008-01-01

Cane-based Celotex(trademark) has been used extensively in various Department of Energy (DOE) packages as a thermal insulator and impact absorber. Cane-based Celotex(trademark) fiberboard was only manufactured by Knight-Celotex Fiberboard at their Marrero Plant in Louisiana. However, Knight-Celotex Fiberboard shut down their Marrero Plant in early 2007 due to impacts from hurricane Katrina and other economic factors. Therefore, cane-based Celotex(trademark) fiberboard is no longer available for use in the manufacture of new shipping packages requiring the material as a component. Current consolidation plans for the DOE Complex require the procurement of several thousand new Model 9975 shipping packages requiring cane-based Celotex(trademark) fiberboard. Therefore, an alternative to cane-based Celotex(trademark) fiberboard is needed. Knight-Celotex currently manufactures Celotex(trademark) fiberboard from other cellulosic materials, such as hardwood and softwood. A review of the relevant literature has shown that softwood-based Celotex(trademark) meets all parameters important to the Model 9975 shipping package

1999-10-01

Here we develop the theory of RNA computing and a method for solving the 'knight problem' as an instance of a satisfiability (SAT) problem. Using only biological molecules and enzymes as tools, we developed an algorithm for solving the knight problem (3 x 3 chess board) using a 10-bit combinatorial pool and sequential RNase H digestions. The results of preliminary experiments presented here reveal that the protocol recovers far more correct solutions than expected at random, but the persistence of errors still presents the greatest challenge.

We describe our experience porting the Regensburg implementation of the DD-αAMG solver from QPACE 2 to QPACE 3. We first review how the code was ported from the first generation Intel Xeon Phi processor (Knights Corner) to its successor (Knights Landing). We then describe the modifications in the communication library necessitated by the switch from InfiniBand to Omni-Path. Finally, we present the performance of the code on a single processor as well as the scaling on many nodes, where in both cases the speedup factor is close to the theoretical expectations.

2005-05-01

We compared the stonefly diversity sampled from 11 selected sites in the Gunnison River Basin over the last three years to the stonefly diversity recorded by Knight (1965) from the same or nearby sites. The 11 sites in this study were chosen from the 22 sites reported by Knight (1965) because they represented mainstem Gunnison River sites that would be predicted to experience the most alteration due to anthropogenic changes such as the construction of impoundments, differences in land use patterns, and effects from the increase in human population of the region. We have been unable to locate ten of the stonefly species that were historically found and we presume that they have gone locally extinct or have become increasingly rare. We have also found six species present today that were not historically reported from Knight (1965). Maps showing current and historical stonefly diversity and distribution have been produced using ArcGIS and analyzed with relevant geographical data to form hypotheses to account for specific changes in the stonefly fauna of the basin.

Interactions between wolves and female grizzly bears with cubs in Yellowstone National Park

2004-01-01

Gray wolves (Canis lupus) were extirpated from Yellowstone National Park (YNP) by the 1920s through predator control actions (Murie 1940,Young and Goldman 1944, Weaver 1978), then reintroduced into the park from 1995 to 1996 to restore ecological integrity and adhere to legal mandates (Bangs and Fritts 1996, Phillips and Smith 1996, Smith et al. 2000). Prior to reintroduction, the potential effects of wolves on the region’s threatened grizzly bear (Ursus arctos) population were evaluated (Servheen and Knight 1993). In areas where wolves and grizzly bears are sympatric, interspecific killing by both species occasionally occurs (Ballard 1980, 1982; Hayes and Baer 1992). Most agonistic interactions between wolves and grizzly bears involve defense of young or competition for carcasses (Murie 1944, 1981; Ballard 1982; Hornbeck and Horejsi 1986; Hayes and Mossop 1987; Kehoe 1995; McNulty et al. 2001). Servheen and Knight (1993) predicted that reintroduced wolves could reduce the frequency of winter-killed and disease-killed ungulates available for bears to scavenge, and that grizzly bears would occasionally usurp wolf-killed ungulate carcasses. Servheen and Knight (1993) hypothesized that interspecific killing and competition for carcasses would have little or no population level effect on either species.

Temperature dependences of the integral intensity and NMR signals Knight shift in 199 Hg nuclei are measured for liquid and solid mercury introduced into the porous coal and silica gel. The decrease in the crystallization completion temperature and small temperature hysteresis (from 4 up to 9 K) between melting and crystallization are identified. Mercury melting temperature in pores coincided with melting temperature of the bulk mercury. NMR signal from crystalline mercury under conditions of limited geometry was observed for the first time. It is ascertained that Knight shift for mercury in the pores both in liquid and crystalline phases is lesser than for the bulk mercury [ru

We present {sup 103}Rh NMR studies for the superconductor Rh{sub 17}S{sub 15} (T{sub c} 5.4 K). We have identified the observed NMR lines corresponding to four different Rh sites in the cubic unit cell and deduced the temperature (T) dependence of the Knight shift components in Rh 24m site whose point symmetry is not axial. The isotropic part of the Knight shift K decreases with T in the normal state, indicating the negative hyperfine coupling and the enhancement of the spin susceptibility at lower T. The sudden change of K below T{sub c} is an indication of the spin-singlet Cooper paring.

NMR studies of metallic tin confined within porous matrices

2007-01-01

119 Sn NMR studies were carried out for metallic tin confined within synthetic opal and porous glass. Tin was embedded into nanoporous matrices in the melted state under pressure. The Knight shift for liquid confined tin was found to decrease with decreasing pore size. Correlations between NMR line shapes, Knight shift, and pore filling were observed. The melting and freezing phase transitions of tin under confinement were studied through temperature dependences of NMR signals upon warming and cooling. Melting of tin within the opal matrix agreed well with the liquid skin model suggested for small isolated particles. The influence of the pore filling on the melting process was shown

A Diachronic Study of Ontological Perspectives from Mircea Eliade and Ioan Petru Culianu’s Literary and Scientific works: the Acceptance of “The Other”

Directory of Open Access Journals (Sweden)

Georgiana – Claudia Mihail

2016-12-01

Full Text Available The aim of this article is to show the fact that there is a continuity of ideas between Mircea Eliade and Ioan Petru Culianu’s systems of thought. Mircea Eliade is fascinated with the power of active imagination, illustrated by myths and symbols which are typical of collective unconscious, because they have been used from the beginning of this world up to the contemporary world. However, we can find such representations in Mircea Eliade and Ioan Petru Culianu’s both scientific and literary works. The comparative interdisciplinary approach is used in this article. On the one hand, there is the comparison between Mircea Eliade and Ioan Petru Culianu’s systems of thought and on the other hand, the interdisciplinary approach arises from the connections established between various sciences, like: the history of religions, anthropology, philosophy and natural sciences. The similarities and differences between their systems of thought are illustrated in this article. Firstly, the description of Mircea Eliade’s scientific system includes the diachronic study of religious ideas and the emphasis on human active imagination as a mechanism of compensation for the ontological suffering. Secondly, the principles of the universal method belonging to Ioan Petru Culianu, the mythical and symbolic representations from the Romanian writer’s literary works: The Emerald Game and Hesperus are also illustrated in this article. Researchers in the philological field can use both the comparative interdisciplinary approach in their future activity and the premise of continuity between Mircea Eliade and his disciple’s systems of thought. Apart from the main approach and premise of this article, the original perspective is represented by the mythical and symbolic representations from Ioan Petru Culianu’s science fiction novel entitled Hesperus.

A new machairodont from the Palmetto Fauna (early Pliocene) of Florida, with comments on the origin of the Smilodontini (Mammalia, Carnivora, Felidae).

2013-01-01

South-central Florida's latest Hemphillian Palmetto Fauna includes two machairodontine felids, the lion-sized Machairodus coloradensis and a smaller, jaguar-sized species, initially referred to Megantereon hesperus based on a single, relatively incomplete mandible. This made the latter the oldest record of Megantereon, suggesting a New World origin of the genus. Subsequent workers variously accepted or rejected this identification and biogeographic scenario. Fortunately, new material, which preserves previously unknown characters, is now known for the smaller taxon. The most parsimonious results of a phylogenetic analysis using 37 cranio-mandibular characters from 13 taxa place it in the Smilodontini, like the original study; however, as the sister-taxon to Megantereon and Smilodon. Accordingly, we formally describe Rhizosmilodon fiteae gen. et sp. nov. Rhizosmilodon, Megantereon, and Smilodon ( = Smilodontini) share synapomorphies relative to their sister-taxon Machairodontini: serrations smaller and restricted to canines; offset of P3 with P4 and p4 with m1; complete verticalization of mandibular symphysis; m1 shortened and robust with widest point anterior to notch; and extreme posterior "lean" to p3/p4. Rhizosmilodon has small anterior and posterior accessory cusps on p4, a relatively large lower canine, and small, non-procumbent lower incisors; all more primitive states than in Megantereon and Smilodon. The former also differs from Megantereon and Smilodon gracilis by having a very small mandibular flange. Rhizosmilodon is the oldest known member of the Smilodontini, suggesting that the tribe originated in North America. Two more derived, similar-sized species evolved in parallel during the Blancan, Megantereon hesperus and Smilodon gracilis. The former is rarer, known only from the north-central and northwestern US, and presumably dispersed into the Old World. The latter is known from the eastern and southern US, and dispersed into South America.

Early events in the evolution of spider silk genes.

Full Text Available Silk spinning is essential to spider ecology and has had a key role in the expansive diversification of spiders. Silk is composed primarily of proteins called spidroins, which are encoded by a multi-gene family. Spidroins have been studied extensively in the derived clade, Orbiculariae (orb-weavers, from the suborder Araneomorphae ('true spiders'. Orbicularians produce a suite of different silks, and underlying this repertoire is a history of duplication and spidroin gene divergence. A second class of silk proteins, Egg Case Proteins (ECPs, is known only from the orbicularian species, Lactrodectus hesperus (Western black widow. In L. hesperus, ECPs bond with tubuliform spidroins to form egg case silk fibers. Because most of the phylogenetic diversity of spiders has not been sampled for their silk genes, there is limited understanding of spidroin gene family history and the prevalence of ECPs. Silk genes have not been reported from the suborder Mesothelae (segmented spiders, which diverged from all other spiders >380 million years ago, and sampling from Mygalomorphae (tarantulas, trapdoor spiders and basal araneomorph lineages is sparse. In comparison to orbicularians, mesotheles and mygalomorphs have a simpler silk biology and thus are hypothesized to have less diversity of silk genes. Here, we present cDNAs synthesized from the silk glands of six mygalomorph species, a mesothele, and a non-orbicularian araneomorph, and uncover a surprisingly rich silk gene diversity. In particular, we find ECP homologs in the mesothele, suggesting that ECPs were present in the common ancestor of extant spiders, and originally were not specialized to complex with tubuliform spidroins. Furthermore, gene-tree/species-tree reconciliation analysis reveals that numerous spidroin gene duplications occurred after the split between Mesothelae and Opisthothelae (Mygalomorphae plus Araneomorphae. We use the spidroin gene tree to reconstruct the evolution of amino acid

Shaw, R.

1997-01-01

This paper examines the steps to be taken by a corporation and its board in order to be properly prepared before a hostile takeover bid is made. The procedures and steps to be followed in responding to a bid with a view to maximizing value for shareholders are also outlined. Reasons why a company may become target for a hostile takeover bid are reviewed, followed by a more detailed examination of the responsibilities of a board in responding to a takeover bid. These responsibilities include the adoption of a shareholders' rights plan ('poison pill'), review of executive employment contracts, making sure that a corporate indemnification agreement and directors' and officers' liability insurance plan are in place, implementation of structural deterrents, investor communication plans, preparing the 'black book', creating or updating the list of 'white knights', designating a data room, entering into confidentiality agreements with white knights, preparation of a response timetable, review of recent takeover bids, strategies for dealing with hostile bidders, strategies for enticing one or more a white knights to enter the bidding. Sample copy of a confidentiality agreement is contained in Schedule A. A list of break-up fees in recent Canadian mergers and acquisitions transactions is provided in Schedule B. 24 refs

Democracy, war and peace: the bitter laughter of Aristophanes

Directory of Open Access Journals (Sweden)

Fernanda Yazbek Rivitti

2009-12-01

Full Text Available This article aims to develop a comparative study between two comedies of Aristophanes, The Acharnians and The Knights, bringing to light the building of critical thinking of Aristophanes concerning Athenian democracy of his time. The analysis of the text focuses on the convergence of both as revealing contradictions in Athenian democratic practices in times of war. This article also examines the dichotomy public / private in The Acharnians and the relationship between the people and their rulers, in The Knights. The dialogue between the two texts is explored not only in the bitter satire of Aristophanes, but in the only solution that appears in both texts regarding a time of war and a political system in crisis: the consummation of peace.

Chess players' eye movements reveal rapid recognition of complex visual patterns: Evidence from a chess-related visual search task.

Science.gov (United States)

Sheridan, Heather; Reingold, Eyal M

2017-03-01

To explore the perceptual component of chess expertise, we monitored the eye movements of expert and novice chess players during a chess-related visual search task that tested anecdotal reports that a key differentiator of chess skill is the ability to visualize the complex moves of the knight piece. Specifically, chess players viewed an array of four minimized chessboards, and they rapidly searched for the target board that allowed a knight piece to reach a target square in three moves. On each trial, there was only one target board (i.e., the "Yes" board), and for the remaining "lure" boards, the knight's path was blocked on either the first move (the "Easy No" board) or the second move (i.e., "the Difficult No" board). As evidence that chess experts can rapidly differentiate complex chess-related visual patterns, the experts (but not the novices) showed longer first-fixation durations on the "Yes" board relative to the "Difficult No" board. Moreover, as hypothesized, the task strongly differentiated chess skill: Reaction times were more than four times faster for the experts relative to novices, and reaction times were correlated with within-group measures of expertise (i.e., official chess ratings, number of hours of practice). These results indicate that a key component of chess expertise is the ability to rapidly recognize complex visual patterns.

FY17 CSSE L2 Milestone Report: Analyzing Power Usage Characteristics of Workloads Running on Trinity.

Energy Technology Data Exchange (ETDEWEB)

Pedretti, Kevin [Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)

2017-09-01

This report summarizes the work performed as part of a FY17 CSSE L2 milestone to in- vestigate the power usage behavior of ASC workloads running on the ATS-1 Trinity plat- form. Techniques were developed to instrument application code regions of interest using the Power API together with the Kokkos profiling interface and Caliper annotation library. Experiments were performed to understand the power usage behavior of mini-applications and the SNL/ATDM SPARC application running on ATS-1 Trinity Haswell and Knights Landing compute nodes. A taxonomy of power measurement approaches was identified and presented, providing a guide for application developers to follow. Controlled scaling study experiments were performed on up to 2048 nodes of Trinity along with smaller scale ex- periments on Trinity testbed systems. Additionally, power and energy system monitoring information from Trinity was collected and archived for post analysis of "in-the-wild" work- loads. Results were analyzed to assess the sensitivity of the workloads to ATS-1 compute node type (Haswell vs. Knights Landing), CPU frequency control, node-level power capping control, OpenMP configuration, Knights Landing on-package memory configuration, and algorithm/solver configuration. Overall, this milestone lays groundwork for addressing the long-term goal of determining how to best use and operate future ASC platforms to achieve the greatest benefit subject to a constrained power budget.

Introduction to a Forum on the Judgment-based Approach to Entrepreneurship

DEFF Research Database (Denmark)

Foss, Nicolai Juul; Klein, Peter G.

2015-01-01

Over the last three decades entrepreneurship has become a hot topic in economics and management. Much of the entrepreneurship research literature has built upon insights of economists such as Schumpeter, Knight, and Kirzner, each of whom has inspired a distinct strand of entrepreneurship theory...... and application. Schumpeterian innovation and Kirznerian alertness are the best-known concepts of entrepreneurship, but a newer research stream is building on Knight's idea of entrepreneurship as judgmental decision-making under uncertainty. What we call the judgment-based view models entrepreneurs as owning......, controlling, and combining heterogeneous assets, which differ in their attributes, and deploying these assets within a firm to produce goods and services in anticipation of economic profit. This Forum presents three papers that develop, extend, and challenge the judgment-based view of entrepreneurship...

Comparative mitogenomic analysis of mirid bugs (Hemiptera: Miridae) and evaluation of potential DNA barcoding markers.

Science.gov (United States)

Wang, Juan; Zhang, Li; Zhang, Qi-Lin; Zhou, Min-Qiang; Wang, Xiao-Tong; Yang, Xing-Zhuo; Yuan, Ming-Long

2017-01-01

The family Miridae is one of the most species-rich families of insects. To better understand the diversity and evolution of mirids, we determined the mitogenome of Lygus pratenszs and re-sequenced the mitogenomes of four mirids (i.e., Apolygus lucorum , Adelphocoris suturalis , Ade. fasciaticollis and Ade. lineolatus ). We performed a comparative analysis for 15 mitogenomic sequences representing 11 species of five genera within Miridae and evaluated the potential of these mitochondrial genes as molecular markers. Our results showed that the general mitogenomic features (gene content, gene arrangement, base composition and codon usage) were well conserved among these mirids. Four protein-coding genes (PCGs) ( cox1 , cox3 , nad1 and nad3 ) had no length variability, where nad5 showed the largest size variation; no intraspecific length variation was found in PCGs. Two PCGs ( nad4 and nad5 ) showed relatively high substitution rates at the nucleotide and amino acid levels, where cox1 had the lowest substitution rate. The Ka/Ks values for all PCGs were far lower than 1 (barcode sequences were always larger than 1 (1.34 -15.20), indicating that the 658 bp sequences of cox1 may be not the appropriate marker due to positive selection or selection relaxation. Phylogenetic analyses based on two concatenated mitogenomic datasets consistently supported the relationship of Nesidiocoris + ( Trigonotylus + ( Adelphocoris + ( Apolygus + Lygus ))), as revealed by nad4 , nad5 , rrnL and the combined 22 transfer RNA genes (tRNAs), respectively. Taken sequence length, substitution rate and phylogenetic signal together, the individual genes ( nad4 , nad5 and rrnL ) and the combined 22 tRNAs could been used as potential molecular markers for Miridae at various taxonomic levels. Our results suggest that it is essential to evaluate and select suitable markers for different taxa groups when performing phylogenetic, population genetic and species identification studies.

J. M. W. Turner's painting "The unpaid bill, or the dentist reproving his son's prodigality".

Science.gov (United States)

Bishop, M; Gelbier, S; King, J

2004-12-25

In November 2002, the BDA News carried an item, illustrated with a colour reproduction, describing a painting of a Georgian dentist's rooms by Joseph Mallord William Turner (1775-1851), one of the most respected of English artists, which was shortly to come up for auction at Christies' Rooms in London. This work, first exhibited in 1808, was entitled "The unpaid bill, or the dentist reproving his son's prodigality", and had originally been commissioned by the connoisseur Richard Payne Knight (1750-1824). "The examiner", a contemporary London journal, identifies the 'cradle-piece' for the commission as being a Rembrandt which Payne Knight owned, and the journalist Robert Hunt said that Turner had more than come up to the task of showing that a modern could handle light as well as the old master, 'for a picture of colouring and effect, it is ... inestimable'.

In 1995, a three-year study was initiated to assess the current status of bat species of concern, elucidate distribution and relative abundance, and obtain information on roosting sites of bats. The authors captured and released 1532 bats of 15 species (Myotis californicus, M. ciliolabrum, M. evotis, M. thysanodes, M. volans, M. yumanensis, Lasiurus cinereus, Lasionycteris noctivagans, Pipistrellus hesperus, Eptesicus fuscus, Euderma maculatum, Corynorhinus townsendii, Antrozous pallidus, Tadarida brasiliensis, and Nyctinomops macrotis) and followed 32 bats of eight species (M. evotis, M. thysanodes, M. volans, E. fuscus, E. maculatum, C. townsendii, A. pallidus, and N. macrotis) to 51 active diurnal roosts. The most abundant species were L. noctivagans, E. fuscus, L. cinereus, M. evotis, M. volans, and M. ciliolabrum. Most of these species are typical inhabitants of ponderosa pine-mixed coniferous forests.

“Things are Complicated”: Paul Cornell at Marvel and DC

Directory of Open Access Journals (Sweden)

Martin Flanagan

2017-12-01

Full Text Available Paul Cornell’s work for the ‘Big Two’ U.S. comic publishers transfers a distinctly British (mostly English sensibility into a field where cues normally revolve around American cultural iconography and values. The key to his authorship is Cornell’s homespun method which, unlike 1970s and 1980s efforts of Marvel’s UK wing that transplanted American characters into a postcard-like Britain, explores a British dimension of the Marvel Universe that offers a challenge to the codes of that realm. Whether working with established heroes such as Captain Britain, twists on archetypes like Knight and Squire (English analogues of Batman and Robin, or superheroic ‘big guns’ like Wolverine, Cornell writes against tired, automatic canonicity. This paper mainly focuses on the directly British representations in the Cornell titles Captain Britain and MI-13 (2008-9 and Knight and Squire (2010.

Trends in sea otter population abundance in western Prince William Sound, Alaska: Progress toward recovery following the 1989 Exxon Valdez oil spill

Science.gov (United States)

Bodkin, James L.; Ballachey, Brenda E.; Esslinger, George G.

2011-01-01

Sea otters in western Prince William Sound (WPWS) and elsewhere in the Gulf of Alaska suffered widespread mortality as a result of oiling following the 1989 T/V Exxon Valdez oil spill. Following the spill, extensive efforts have been directed toward identifying and understanding long-term consequences of the spill and the process of recovery. We conducted annual aerial surveys of sea otter abundance from 1993 to 2009 (except for 2001 and 2006) in WPWS. We observed an increasing trend in population abundance at the scale of WPWS through 2000 at an average annual rate of 4 percent: however, at northern Knight Island where oiling was heaviest and sea otter mortality highest, no increase in abundance was evident by 2000. We continued to see significant increase in abundance at the scale of WPWS between 2001 and 2009, with an average annual rate of increase from 1993 to 2009 of 2.6 percent. We estimated the 2009 population size of WPWS to be 3,958 animals (standard error=653), nearly 2,000 animals more than the first post-spill estimate in 1993. Surveys since 2003 also have identified a significant increasing trend at the heavily oiled site in northern Knight Island, averaging about 25 percent annually and resulting in a 2009 estimated population size of 116 animals (standard error=19). Although the 2009 estimate for northern Knight Island remains about 30 percent less than the pre-spill estimate of 165 animals, we interpret this trend as strong evidence of a trajectory toward recovery of spill-affected sea otter populations in WPWS.

New light on a dark subject: On the use of fluorescence data to deduce redox states of natural organic matter (NOM)

Science.gov (United States)

Macalady, Donald L.; Walton-Day, Katherine

2009-01-01

This paper reports the use of excitation-emission matrix fluorescence spectroscopy (EEMS), parallel factor statistical analysis (PARAFAC), and oxidation-reduction experiments to examine the effect of redox conditions on PARAFAC model results for aqueous samples rich in natural organic matter. Fifty-four aqueous samples from 11 different geographic locations and two plant extracts were analyzed untreated and after chemical treatments or irradiation were used in attempts to change the redox status of the natural organic matter. The EEMS spectra were generated and modeled using a PARAFAC package developed by Cory and McKnight (2005). The PARAFAC model output was examined for consistency with previously reported relations and with changes expected to occur upon experimental oxidation and reduction of aqueous samples. Results indicate the implied fraction of total sample fluorescence attributed to quinone-like moieties was consistent (0.64 to 0.78) and greater than that observed by Cory and McKnight (2005). The fraction of the quinone-like moieties that was reduced (the reducing index, RI) showed relatively little variation (0.46 to 0.71) despite attempts to alter the redox status of the natural organic matter. The RI changed little after reducing samples using zinc metal, oxidizing at high pH with air, or irradiating with a Xenon lamp. Our results, however, are consistent with the correlations between the fluorescence indices (FI) of samples and the ratio of PARAFAC fitting parameters suggested by Cory and McKnight (2005), though we used samples with a much narrower range of FI values.

Highlights: • Quadrupole NMR with first-principles calculations probes local site preferences. • Cu/Ge ratio is clarified vs. the ideal Zintl composition. • Modified Becke–Johnson exchange potential agrees well with NMR Knight shifts. - Abstract: Ba{sub 8}Cu{sub x}Ge{sub 46-x} is a type-I clathrate material that forms as a semiconductor in a narrow composition range corresponding to the electron-balanced Zintl composition, with x = 5.3. We use NMR spectroscopy combined with ab initio electronic structure calculations to probe the electronic and structural behavior of these materials. Computational results based on a superstructure model for the atomic configuration of the alloy provide good agreement with the electric quadrupole-broadened NMR lineshapes. Modeling using the modified Becke–Johnson (TB-mBJ) exchange potential is also shown to agree well with experimental NMR Knight shifts. The results indicate that the Cu–Ge balance is the main factor determining the carrier density, within a narrow stability range near the ideal Zintl composition.

We will present latest {sup 75}As NMR data in the normal state of the stoichiometric superconductor RbFe{sub 2}As{sub 2}. This will be put into context to known results for the heavily hole-doped compound KFe{sub 2}As{sub 2}. The static and dynamic magnetic correlations were probed via measurements of the Knight shift and nuclear spin-lattice relaxation rate in a wide temperature range from 0.3 to 300 K. Although neither a magnetic nor a structural transition were observed down to lowest temperatures, the very close proximity of the ground state to a magnetic instability is indicated by a pronounced Curie-Weiss-like behavior of spin fluctuations. At around 100 K, we find a maximum of the Knight shift and a changing exponent of the temperature-dependent relaxation rate. This is phenomenologically similar to the case of KFe{sub 2}As{sub 2} and was proposed to stem from a incoherence-coherence crossover mechanism of electronic correlations.

209Bi NMR in heavy-electron system YbBiPt

International Nuclear Information System (INIS)

Reyes, A.P.; Le, L.P.; Heffner, R.H.; Ahrens, E.T.; Fisk, Z.; Canfield, P.C.

1994-01-01

Bismuth NMR Knight shift and spin lattice relaxation rate 1/T 1 are reported between 35--325K in the low-carrier heavy fermion system YbBiPt. The Knight shift is strongly temperature dependent and negative. Its temperature dependence tracks the bulk susceptibility with a hyperfine coupling constant A hf = -7.89 kOe/μB. At low temperatures 1/T 1 exhibits a dramatic increase, such that the average 4f spin correlation time τ f shows a crossover behavior at about 75K. The rate 1/τ f is proportional to temperature, but with a different proportionality constant above and below about 75K. The linear temperature dependence is consistent with non-interacting 4f local moments which are relaxed via Korringa-type scattering with the conduction electrons. Below 75K, we infer that the reduced thermal excitation of a higher crystal-field multiplet is responsible for the dramatic decrease in the rate of 4f relaxation

NMR study of electrode materials for lithium ion-batteries; Etude par RMN de materiaux d'electrode pour batteries lithium-ion

Energy Technology Data Exchange (ETDEWEB)

Chazel, C.

2006-01-15

This work is devoted to the study of LiMO{sub 2} et LiM{sub 2}O{sub 4} (M: transition metal) intercalation compounds used as electrode material for lithium-ion batteries. Solid state NMR allows one to characterise the local environment of the lithium ions present in these phases by the use of the hyperfine interactions due to the presence of some electron spin density coming from localised electrons (Fermi-contact shift) or itinerant electrons (Knight shift) on the lithium nucleus. By following the transformation of the LiNiO{sub 2} layered phase into the LiNi{sub 2}O{sub 4} spinel material using lithium NMR, we studied the nature of the asymmetric signal observed for LiNiO{sub 2}, and the influence of the departure from the ideal stoichiometry; we showed a coupled ion/electron hopping in Li{sub X}NiO{sub 2} phases linked to Li/vacancy and Ni{sup 3+}/Ni{sup 4+} ordering, and finally showed the existence of structural defects within the LiNi{sub 2}O{sub 4} spinel phase obtained by thermal treatment of Li{sub 0.5}NiO{sub 2}. Lithium NMR of the intercalated materials obtained from the LiTi{sub 2}O{sub 4} and Li{sub 4}Ti{sub 5}O{sub 12} spinels showed a metallic behaviour for Li{sub 2}Ti{sub 2}O{sub 4} with a Knight shift of the NMR signal similar to that of LiTi{sub 2}O{sub 4}, and signals intermediate in nature between Knight and Fermi-contact shifts for Li{sub 7}Ti{sub 5}O{sub 12}.

Comparative mitogenomic analysis of mirid bugs (Hemiptera: Miridae and evaluation of potential DNA barcoding markers

Directory of Open Access Journals (Sweden)

2017-08-01

Full Text Available The family Miridae is one of the most species-rich families of insects. To better understand the diversity and evolution of mirids, we determined the mitogenome of Lygus pratenszs and re-sequenced the mitogenomes of four mirids (i.e., Apolygus lucorum, Adelphocoris suturalis, Ade. fasciaticollis and Ade. lineolatus. We performed a comparative analysis for 15 mitogenomic sequences representing 11 species of five genera within Miridae and evaluated the potential of these mitochondrial genes as molecular markers. Our results showed that the general mitogenomic features (gene content, gene arrangement, base composition and codon usage were well conserved among these mirids. Four protein-coding genes (PCGs (cox1, cox3, nad1 and nad3 had no length variability, where nad5 showed the largest size variation; no intraspecific length variation was found in PCGs. Two PCGs (nad4 and nad5 showed relatively high substitution rates at the nucleotide and amino acid levels, where cox1 had the lowest substitution rate. The Ka/Ks values for all PCGs were far lower than 1 (<0.59, but the Ka/Ks values of cox1-barcode sequences were always larger than 1 (1.34 –15.20, indicating that the 658 bp sequences of cox1 may be not the appropriate marker due to positive selection or selection relaxation. Phylogenetic analyses based on two concatenated mitogenomic datasets consistently supported the relationship of Nesidiocoris + (Trigonotylus + (Adelphocoris + (Apolygus + Lygus, as revealed by nad4, nad5, rrnL and the combined 22 transfer RNA genes (tRNAs, respectively. Taken sequence length, substitution rate and phylogenetic signal together, the individual genes (nad4, nad5 and rrnL and the combined 22 tRNAs could been used as potential molecular markers for Miridae at various taxonomic levels. Our results suggest that it is essential to evaluate and select suitable markers for different taxa groups when performing phylogenetic, population genetic and species identification

Characterization of the electronic properties of YB{sub 4} and YB{sub 6} using {sup 11}B NMR and first-principles calculations

Energy Technology Data Exchange (ETDEWEB)

Jaeger, B.; Paluch, S.; Wolf, W.; Herzig, P.; Zogal, O.J.; Shitsevalova, N.; Paderno, Y

2004-11-30

Two compounds, tetragonal YB{sub 4} and cubic YB{sub 6}, have been investigated by electric-field gradient (EFG) and Knight shift measurements at the boron sites using the {sup 11}B nuclear magnetic resonance (NMR) technique and by performing first-principles calculations. In YB{sub 6} {sup 11}B (I=3/2) NMR spectra reveal patterns typical for an axially symmetric field gradient with a quadrupole coupling frequency of {nu}{sub Q}=600{+-}15 kHz. In the second boride (YB{sub 4}) three different EFGs were observed corresponding to the three inequivalent crystallographic sites for the boron atoms (4h, 4e, and 8j). They correspond to: {nu}{sub Q}(4h)=700{+-}30 kHz with an asymmetry parameter {eta}=0.02{+-}0.02, {nu}{sub Q}(4e)=515{+-}30 kHz, {eta}=0.00+0.02/-0.00, and {nu}{sub Q}(8j)=515{+-}40 kHz, {eta}=0.46{+-}0.08. The Knight shifts measured by magic-angle spinning (MAS) NMR at room temperature are very small being 0.6{+-}8 and -1{+-}8 ppm for YB{sub 4} and YB{sub 6}, respectively. For the theoretical calculations structure optimizations were performed as a first step. For the obtained structural parameters the EFGs were computed within the local-density approximation. Very satisfactory agreement between experimental and theoretical results is obtained both for the structural parameters and the B EFGs, thus confirming the underlying structural models. In addition to the EFGs, band structures, densities of states, and valence-electron densities are presented and the bonding situation in the two yttrium borides is discussed. The band-structure results are compatible with the very low values for the Knight shifts mentioned above.

Numerical Simulations of Upstream Propagating Solitary Waves and Wave Breaking In A Stratified Fjord

Science.gov (United States)

Stastna, M.; Peltier, W. R.

In this talk we will discuss ongoing numerical modeling of the flow of a stratified fluid over large scale topography motivated by observations in Knight Inlet, a fjord in British Columbia, Canada. After briefly surveying the work done on the topic in the past we will discuss our latest set of simulations in which we have observed the gener- ation and breaking of three different types of nonlinear internal waves in the lee of the sill topography. The first type of wave observed is a large lee wave in the weakly strat- ified main portion of the water column, The second is an upward propagating internal wave forced by topography that breaks in the strong, near-surface pycnocline. The third is a train of upstream propagating solitary waves that, in certain circumstances, form as breaking waves consisting of a nearly solitary wave envelope and a highly unsteady core near the surface. Time premitting, we will comment on the implications of these results for our long term goal of quantifying tidally driven mixing in Knight Inlet.

Apocalyptic souls: the existential (anti hero metaphor in the Metal Gear Solid: Snake Eater, Peace Walker and Ground Zeroes games

Directory of Open Access Journals (Sweden)

Daniel de Vasconcelos Guimarães

2015-06-01

Full Text Available In the present study, I drew a correlation between Søren Kierkegaard’s (1813-1855 existentialist theory and apocalyptic representations in the Metal Gear Solid: Snake Eater, Peace Walker and Ground Zeroes video games (Konami Computer Entertainment Japan, Kojima Productions, 2004, 2010 and 2014. In this successful franchise, the game’s main character, ‘Snake’ personifies ‘the knight of infinite resignation,’ the ‘tragic hero’ in ‘the infinite movement’ towards the achievement of ‘higher causes’. Also, Snake’s mentor ‘The Boss’, who sacrifices herself in order to reconcile the world from its 1960’s Cold War antagonism would represent another Kierkegaard notion called ‘the knight of faith’, who believes in his/her faith (the cause above all things. Such character traits enrich both gameplay and game narrative and the overall experience by introducing philosophical inquiries to the player. The methodology utilized was a free-form semiotic framework with emphasis on the symbolic representations along with Kierkegaard’s existentialism and other philosophical constructs as well.

Full Text Available The Return of D. Quixote, 1926, consummates a stage in Chesterton's life that the critics have called the quixotic period. The departing point for this time period was an essay called The divine parody of D. Quixote (1901 in which the author interprets Cervantes' novel as a performance of the combat between idealism and realism. Sancho Panza portrays the image of the knight embodying common sense and opposed to certain madness that we have come to consider as normal in the world we live. This paradox had been already subject of a witty analysis in the utopian novel The Napoleon of Notting Hill of 1904. It is also explored in other relevant works like the poem entitled Lepanto of 1912. It is only in the Weekly's Review issues where D. Quixote becomes the advocate of the distributionist cause and the return to a medieval society as a symbol of the revival of the knight's virtuousness and of its inspiring prototype, the utopia of a Christian society.

We present {sup 125}Te NMR measurements on CeTe powder at temperatures between 1 and 150K and in magnetic fields between 5 and 8T. CeTe is a rocksalt-type intermetallic compound. It orders antiferromagnetically at T{sub N}{approx}2.2K with a much reduced ordered moment [H.R. Ott, J.K. Kjems, F. Hulliger, Phys. Rev. Lett. 42 20 (1979) 1378]. From our low-temperature NMR spectra we infer the presence of at least three inequivalent Te sites at low temperatures. Considering the crystal structure this result is completely unexpected. The linewidths and the Knight shifts of the individual lines are significantly different and increase substantially with decreasing temperature. They follow the temperature dependence of the magnetic susceptibility above 20K. Above T{sub N}, hyperfine fields of 1.6, 0.8 and 0.0T at the three Te sites per Bohr magneton of Ce moment are deduced from Knight shift vs. magnetic susceptibility data. These values are typical for transferred hyperfine fields via conduction electrons.

Non-invasive determination of the complete elastic moduli of spider silks

Science.gov (United States)

Koski, Kristie J.; Akhenblit, Paul; McKiernan, Keri; Yarger, Jeffery L.

2013-03-01

Spider silks possess nature’s most exceptional mechanical properties, with unrivalled extensibility and high tensile strength. Unfortunately, our understanding of silks is limited because the complete elastic response has never been measured—leaving a stark lack of essential fundamental information. Using non-invasive, non-destructive Brillouin light scattering, we obtain the entire stiffness tensors (revealing negative Poisson’s ratios), refractive indices, and longitudinal and transverse sound velocities for major and minor ampullate spider silks: Argiope aurantia, Latrodectus hesperus, Nephila clavipes, Peucetia viridans. These results completely quantify the linear elastic response for all possible deformation modes, information unobtainable with traditional stress-strain tests. For completeness, we apply the principles of Brillouin imaging to spatially map the elastic stiffnesses on a spider web without deforming or disrupting the web in a non-invasive, non-contact measurement, finding variation among discrete fibres, junctions and glue spots. Finally, we provide the stiffness changes that occur with supercontraction.

Magnetic excitation and local magnetic susceptibility of the excitonic insulator Ta2NiSe5 investigated by 77Se NMR

Science.gov (United States)

Li, Shang; Kawai, Shunsuke; Kobayashi, Yoshiaki; Itoh, Masayuki

2018-04-01

77Se NMR measurements were made on polycrystalline and single-crystalline samples to elucidate local magnetic susceptibility and magnetic excitation of Ta2NiSe5 , which is proposed to undergo an exciton condensation accompanied by a structural transition at Tc=328 K . We determine the 77Se Knight shift tensors for the three Se sites and analyze their anisotropy based on the site symmetry. The temperature dependence of the Knight shift is discussed on the basis of spin and orbital susceptibilities calculated for two-chain and two-dimensional three-band models. The large fraction of the Se 4 p orbital polarization due to the mixing between Ni 3 d and Se 4 p orbitals is estimated from the analysis of the transferred hyperfine coupling constant. Also the nuclear spin-lattice relaxation rate 1 /T1 is found not to show a coherent peak just below Tc and to obey the thermally activated temperature dependence with a spin gap energy of 1770 ±40 K . This behavior of 1 /T1 monitors the exciton condensation as proposed by the theoretical study of 1 /T1 based on the three-chain Hubbard model for the excitonic insulator.

Full Text Available The report focuses on the mythical structure hidden within the popular movies from its golden times to the present days. More specifically, it deals with the epic, which, although not being exactly mythology, possesses many of its characteristics. Nowadays, it is the epic the one invading both the big and the small screen, even more than the literature. This occurs through movies and TV series that are joined by their stylistic and structural elements: strong realism, a complex narrative structure, a popular attitude, fantastic elements, a struggling hero full of dark sides, and a gloomy vision of reality hiding a slight hope. Within this framework, it is important to understand if, beyond the grandeur of the massive scenes, there is indeed some material belonging to the traditional western epic. Here, without entering into the merits of history, we will try to find out whether the term „Epic” is used properly when talking about movies like: The Lord of the Rings series by Peter Jackson, 300 by Zack Snyder especially the Dark Knight trilogy, where the one only known as Batman becomes the Dark Knight.

Local magnetic susceptibility, spin dynamics, and charge order in the quasi-one-dimensional conductor β -Li0.33V2O5 investigated by site-selective 51V NMR

51V NMR measurements have been conducted on a single crystal of the quasi-one-dimensional conductor β -Li0.33V2O5 which undergoes a metal-insulator (MI) transition at TMI˜170 K. In the metallic phase, we obtain 51V Knight shift and electric field gradient tensors. From the analysis of the 51V Knight shifts, we find that the charge disproportionation appears even in the metallic state and the electronic structure is represented within a model of weakly coupled ladders containing two types of ladders with distinct carrier densities. Based on the 51V nuclear spin-lattice relaxation rate, we discuss the spin dynamics within the one-dimensional electron gas model. From the analysis of several nonmagnetic V5 + spectra observed in the insulating phase, we propose a possible charge-order pattern which has a superlattice modulation larger than those in other family members of β -A0.33V2O5 (A =Na and Ag). Finally, we discuss the A -ion dependence of the electronic structure, the charge disproportionation, and the charge order in β -A0.33V2O5 .

Space efficient opposed-anvil high-pressure cell and its application to optical and NMR measurements up to 9 GPa

We have developed a new type of opposed-anvil high pressure cell with substantially improved space efficiency. The clamp cell and the gasket are made of non-magnetic Ni-Cr-Al alloy. Non-magnetic tungsten carbide (NMWC) is used for the anvils. The assembled cell with the dimension φ29 mm x 41 mm is capable of generating pressure up to 9 GPa over a relatively large volume of 7 mm 3 . Our cell is particularly suitable for those experiments which require large sample space to achieve good signal-to-noise ratio, such as the nuclear magnetic resonance (NMR) experiment. Argon is used as the pressure transmitting medium to obtain good hydrostaticity. The pressure was calibrated in situ by measuring the fluorescence from ruby through a transparent moissanite (6H-SiC) window. We have measured the pressure and temperature dependences of the 63 Cu nuclear-quadrupole-resonance (NQR) frequency of Cu 2 O, the in-plane Knight shift of metallic tin, and the Knight shift of platinum. These quantities can be used as reliable manometers to determine the pressure values in situ during the NMR/NQR experiments up to 9 GPa. (author)

Political Ideology, Confidence in Science, and Participation in Alzheimer Disease Research Studies.

Americans' confidence in science varies based on their political ideology. This ideological divide has potentially important effects on citizens' engagement with and participation in clinical studies of Alzheimer disease (AD). A probability sample of 1583 Americans was surveyed about their willingness to participate in longitudinal AD research and about their political attitudes. These survey results were compared with a survey of 382 participants in a longitudinal AD study at the Knight Alzheimer Disease Research Center. Among Americans, more conservative ideology decreases willingness to participate in a hypothetical longitudinal cohort study of AD both directly and through its negative effect on confidence in science. The Knight Alzheimer Disease Research Center study participants expressed more liberal ideology and greater confidence in science than Americans in general. Of the survey respondents opposed to participation, over a quarter changed to neutral or positive if the study returned their research results to them. Clinical studies of AD are likely biased toward participants who are more liberal and have higher confidence in science than the general population. This recruitment bias may be reduced by lowering the trust demanded of participants through measures such as returning research results to participants.

Full Text Available Up to approximately the 15th century the arms and the armament of a Polish knight were very similar in style to those used in the west: heavy Armour, heavy sword, and heavy horse. However, in the face of the continuous attacks by Tartars, and later on Turks, on Polish territories, the enemy consisting of very light cavalry, on small but very quick and manageable horses, the heavy knights were of little use. Long before the 15th century the armament and the tactics had to be slowly modified and adapted to the enemy's armament and stratagems.

Hasta antes del siglo XV, las armas y armamento de los caballeros polacos eran muy similares en estilo a los utilizados en Occidente: una pesada armadura, una pesada espada, un pesado caballo.

The evidence of unconventional pairing in heavy fermion superconductors and high-Tc superconductors

International Nuclear Information System (INIS)

Tien, C.; Wur, C.S.; Jiang, I.M.

1989-01-01

Recently there has been a great deal of interest in two classes of superconductors, heavy fermion superconductors and high T c copper oxide superconductors. The behavior and nature of superconductivity in these two classes of materials are very similar. The temperature dependences of spin-lattice relaxation time (T 1 ) and spin-spin relaxation time (T 2 ) of 9 Be in UBe 13 are quite similar to those of 63 Cu and 89 Y in YBa 2 Cu 3 O 7-δ . The Knight shift of UBe 13 is unchanged during the superconducting phase transition. The Knight shift of YBa 2 Cu 3 O 7-δ changes from the value in the normal state K n /K s = 1 at T ≥ T c to K n /K s = 0.5 at T = 6 K. Both do not approach zero as expected in BCS theory. The acoustic attenuation is enhanced just below T c instead of rapid drop near T c for these two superconducting system. Neither the enhancement, the temperature variation, nor any other anomalous behaviors appear to be mirrored in EPR data for heavy Fermion superconductors and high T c superconductors. This strongly suggests that the unconventional pairing mechanism which induces superconductivity in heavy fermion materials might also involve in high T c superconductors

Normal-state copper NMR spectra and spin-lattice relaxation rates 1/T 1 have been measured in the planar cuprate system YBa 2 Cu 3 O 7 . With Pr doping the Knight shift K decreases and develops a temperature dependence at both plane and chain sites. Analysis of the bulk susceptibility and NMR data indicate that pair breaking and hole depletion both take part in the suppression of the superconducting transition temperature T c . The Knight shift behavior resembles that in oxygen-deficient YBa 2 Cu 3 O 7-y , as does the temperature dependence of 1/T 1 for plane Cu sites and magnetic field perpendicular to the c axis. This agreement leads to a consistent picture of the role of antiferromagnetic fluctuations in these materials. An analysis of the data in the framework of the phenomenological theory of Millis, Monien, and Pines is given. In the end compound PrBa 2 Cu 3 O 7 the NMR signal from plane Cu sites indicates antiferromagnetic (AF) ordering at a Neel temperature ∼280 K, and in the AF state yields an internal field similar to those found in AF YBa 2 Cu 3 O 6 and La 2 CuO 4 . 32 refs., 7 figs

2014-01-01

In this article we examine the gender differences among hotel employees in service orientation and job satisfaction. To determine these differences, we used a service orientation scale (SOS), developed by Dienhart, Gregoire, Downey and Knight and a job satisfaction scale developed by Lytle. Our assumptions were that there would be significant gender differences in service orientation and job satisfaction. Our research proved factor structures of the two scales we used.

1976-01-01

An NQR spectrometer is described based on a superregenerative oscillator for high sensitivity. The application of a Pound-Knight type oscillator using field effect transistors resulted in higher stability of oscillation amplitude in the desired range of 10 to 50 MHz. The use of a current source allowed to set good signal-to-noise ratio independently of the amplitude of oscillations. For synchronizing of both oscillators a balanced modulator was used. (author)

Astakine 2--the dark knight linking melatonin to circadian regulation in crustaceans.

Directory of Open Access Journals (Sweden)

Apiruck Watthanasurorot

2013-03-01

Full Text Available Daily, circadian rhythms influence essentially all living organisms and affect many physiological processes from sleep and nutrition to immunity. This ability to respond to environmental daily rhythms has been conserved along evolution, and it is found among species from bacteria to mammals. The hematopoietic process of the crayfish Pacifastacus leniusculus is under circadian control and is tightly regulated by astakines, a new family of cytokines sharing a prokineticin (PROK domain. The expression of AST1 and AST2 are light-dependent, and this suggests an evolutionarily conserved function for PROK domain proteins in mediating circadian rhythms. Vertebrate PROKs are transmitters of circadian rhythms of the suprachiasmatic nucleus (SCN in the brain of mammals, but the mechanism by which they function is unknown. Here we demonstrate that high AST2 expression is induced by melatonin in the brain. We identify RACK1 as a binding protein of AST2 and further provide evidence that a complex between AST2 and RACK1 functions as a negative-feedback regulator of the circadian clock. By DNA mobility shift assay, we showed that the AST2-RACK1 complex will interfere with the binding between BMAL1 and CLK and inhibit the E-box binding activity of the complex BMAL1-CLK. Finally, we demonstrate by gene knockdown that AST2 is necessary for melatonin-induced inhibition of the complex formation between BMAL1 and CLK during the dark period. In summary, we provide evidence that melatonin regulates AST2 expression and thereby affects the core clock of the crustacean brain. This process may be very important in all animals that have AST2 molecules, i.e. spiders, ticks, crustaceans, scorpions, several insect groups such as Hymenoptera, Hemiptera, and Blattodea, but not Diptera and Coleoptera. Our findings further reveal an ancient evolutionary role for the prokineticin superfamily protein that links melatonin to direct regulation of the core clock gene feedback loops.

Red Queen Takes White Knight: The Commercialisation of Accounting Education in Australia

Directory of Open Access Journals (Sweden)

Graham Bowrey

2015-09-01

Full Text Available This paper investigates the adaptive and maladaptive consequences of changes resulting from the commercialisation of Australian universities, specifically their accounting schools, and aims to identify the organisational changes triggered by competition that affect the growth of universities over time. The paper synthesises organisational learning theory, benchmarking theory, mimetic isomorphism and institutional theories, which are presented as "the Red Queen", itself an evolutionary theory; this synthesis provides the theoretical underpinning. The Red Queen theory posits that competition triggers organisational learning, which in turn intensifies competition in rivals that ultimately triggers an adaptive response. This selfreinforcing process produces results that may be adaptive or maladaptive. There is evidence to support that “running fast” in terms of Red Queen evolution theory has allowed some universities to place competitive pressure on rivals and achieve elite levels of publications, international accreditation and improved international rankings. This search for improvement, driven by commercialisation, provided ways to improve performance, thus improving the university’s competitive strength. There is also evidence to support the belief that “running slow” provides maladaptive consequences that could affect growth rates, quality and staff performance. The use of the Red Queen hypothesis provides an evolutionary approach to the study of strategy, strategic change and organisations. This provides an opportunity to examine competition in universities as a force that continually disturbs equilibrium.

Electronic cigarettes have caused a sharp debate in the public health community, with some promoting them as a means of harm reduction for tobacco users and some taking a strong stand against them because of fear of renormalising smoking behaviour and interrupting tobacco control progress. People with mental health problems smoke at high rates and e-cigarettes seem a potentially attractive method of cessation in this population, and their use should be studied carefully.

Rotation and Morphology of Comet 252P/LINEAR

Woodney, Laura; Schambeau, Charles A.; Fernandez, Yanga R.

2017-10-01

Comet 252P/LINEAR had an incredibly close approach early in 2016 - minimum distance 0.036 AU on March 21 - that allowed detailed investigation of its behavior. Analysis of observations of the morphology of 252P have resulted in several possible rotational periods. Knight and Schleicher found that repetition of features in narrowband imaging from April 2016 indicated a period of 7.35 +/- 0.05 hr [1]. HST broadband data obtained by Li et al. in March and April partially fit the 7.35 hr period, but found 5.5 hr was a better fit for the April 4 r’ band data [2]. Given this discrepancy, additional observations may shed light on the true rotation state, and we present here the pieces of the puzzle obtained by our group.We observed 252P with the Kitt Peak National Observatory WIYN 0.9 m telescope on 7 nights: May 2 - 5 and June 6,8,9, 2016 using a Harris R filter. An oscillating jet is clearly visible in our data. While there is insufficient phase coverage to determine a best fit period from our data alone, we will present how our observations of the morphology fit the two proposed periods.[1] Knight, M.M and D.G.

Morphological variation, biogeography and local extinction of the northern New Zealand landsnail Placostylus hongii (Gastropoda : Bulimulidae)

International Nuclear Information System (INIS)

Brook, F.J.; McArdle, B.H.

1999-01-01

Placostylus hongii (Lesson) is recorded from sites between Whangaroa and Whangarei on the mainland Northland coast, and from the Poor Knights, Chicken, Mokohinau and Great Barrier islands offshore. There is considerable variation in shell morphology between the various populations, commonly with marked morphological divergence at a local scale but with overlapping variation overall across all populations of the taxon. Patterns of morphological variation show no clear geographic trends and are at least in part related to local environmental factors. Correlations are identified between shell shape and substratum type, and between shell size and vegetation type. Placostylus hongii has a very restricted stratigraphic distribution in mainland Northland, with most if not all of the few known fossil populations post-dating Polynesian settlement at c. 900-700 years BP. We suggest that P. hongii populations on the Poor Knights and possibly also those on the Mokohinau islands are endemic, whereas the mainland populations and those on Great Barier and the Chicken islands have originated from anthropic redistribution of snails in prehistoric time. A high proportion of the mainland P. hongii populations and some offshore island populations became extinct in the last few hundred years as a result of predation by introduced mammals and the modification and destruction of shrubland and forest habitat.

We report {sup 29}Si nuclear magnetic resonance measurements of single crystals and aligned powders of URu{sub 2}Si{sub 2} under pressure in the hidden order and paramagnetic phases. We find that the Knight shift decreases with applied pressure, consistent with previous measurements of the static magnetic susceptibility.

This suppression persists under pressure, and the onset temperature is mildly enhanced.

PERCEPTION OF UNCERTAINTY AND OPERATIONAL PERFORMANCE OF THE BRAZILIAN INDUSTRY FROM 2007 TO 2009

Directory of Open Access Journals (Sweden)

Marta Sambiase Lombardi

2010-11-01

Full Text Available This article poses to explore the relationship between the manager´s perception of uncertainty and the Brazilian industry´s operational performance during the period from 2007 to 2009. This timeframe was chosen because it comprised both positive and negative cycles of the global economic panorama, and thus capable of interfering in the manager´s perception of uncertainty and consequent business strategies. Periods of market fluctuations and more dynamic and complex business environments clearly demonstrate that managerial models which are applicable to static or predictable scenarios, become fragile and of dubious applicability; that is, practices adopted and described in business administration bibliographies might not produce expected results.  A key factor for sound performance is the positioning of companies in relation to future planning (Knight, 2002, the latter defined as actions taken by the entrepreneur given a certain degree of uncertainty, inherent to the management activity.  The relationship between uncertainty and corporate performance has been studied, at least, ever since Knight in 1921. The author affirmed that we live in a world of change and in a world of uncertainty. The level of entrepreneur trust from the National Industry Confederation represented the perception of uncertainty, whilst operational performance was formed as of industrial production and employment IBGE indexes. Results demonstrate that both constructs have equivalent movements during the course of the period, presenting a positive correlation. Key-words: Uncertainty. Operational performance. Trust. 

Knight Mine reclamation: a study of revegetation difficulties in a semi-arid environment

International Nuclear Information System (INIS)

McNearny, R.L.; Wheeler, K.R.

1995-01-01

An analysis of the difficulties associated with the re-establishment of reclamation vegetation on a dry underground coal mine site in southern Utah, USA, is presented. Precipitation amounts, seed mix, seed bed preparation techniques, and soil properties all appeared to be adequate for vegetation establishment at the site. However, failure of repeated revegetation efforts in a redisturbed area of the mine site may have been due to higher soil salinity levels in the area, which may have given 'Kochia scoparia' an initial competitive advantage. Lack of soil moisture and allelopathic effects due to the dense carpet of 'Kochi' may have also contributed to the continued lack of revegation success. 14 refs., 7 figs., 6 tabs

Object identification with deep learning using Intel DAAL on Knights Landing processor [Vidyo

CERN Multimedia

CERN. Geneva

2017-01-01

The problem of object recognition is computationally expensive, especially when large amounts of data is involved. Recently, techniques in deep neural networks (DNN) - including convolutional neural networks and residual neural networks - have shown great recognition accuracy compared to traditional methods (artificial neural networks, decision tress, etc.). However, experience reveals that there are still a number of factors that limit scientists from deriving the full performance benefits of large, DNNs. We summarize these challenges as follows: (1) large number of hyperparameters that have to be tuned against the DNN during training phase, leading to several data re-computations over a large design-space, (2) the share volume of data used for training, resulting in prolonged training time, (3) how to effectively utilize underlying hardware (compute, network and storage) to achieve maximum performance during this training phase. In this presentation, we discuss a cross-layer perspective into realizing effic...

The electronic cigarette: a knight in shining armour or a Trojan horse?†

OpenAIRE

Schluger, Neil W.

2014-01-01

Electronic cigarettes have caused a sharp debate in the public health community, with some promoting them as a means of harm reduction for tobacco users and some taking a strong stand against them because of fear of renormalising smoking behaviour and interrupting tobacco control progress. People with mental health problems smoke at high rates and e-cigarettes seem a potentially attractive method of cessation in this population, and their use should be studied carefully.

Quasiclassical description of multi-band superconductors with two order parameters

Moor, Andreas

2014-05-19

This Thesis deals with multi-band superconductors with two order parameters, i.e., the superconductivity and the spin-density wave, also touching on one-band superconductors with a charge-density wave, as well as with only the superconducting order parameter. Quasiclassical description of suchlike structures is developed and applied to investigation of various effects, inter alia, the Josephson and the proximity effects, the Knight shift, the Larkin-Ovchinnikov-Fulde-Ferrell-like state, and the interplay of the order parameters in coexistence regime. The applicability of the developed approach to pnictides is discussed.

Both methods, Perturbed Angular Correlation (PAC) utilizing radioactive probes and Perturbed Angular Distribution (PAD) following nuclear reactions measure hyperfine interaction parameters and allow to study magnetism on a rather local scale. While both techniques are based on the same theory the underlying concepts are quite different. Examples on local moments, influence of the nearest-neighbor to the magnetic field in ferromagnets, knight shift in nonmagnetic materials, and magnetism in high-temperature superconductors and related oxides illustrate the recent developments within the methods and the improvements in their sensitivity and resolution.

Optimization of Finite-Differencing Kernels for Numerical Relativity Applications

Directory of Open Access Journals (Sweden)

Roberto Alfieri

2018-05-01

Full Text Available A simple optimization strategy for the computation of 3D finite-differencing kernels on many-cores architectures is proposed. The 3D finite-differencing computation is split direction-by-direction and exploits two level of parallelism: in-core vectorization and multi-threads shared-memory parallelization. The main application of this method is to accelerate the high-order stencil computations in numerical relativity codes. Our proposed method provides substantial speedup in computations involving tensor contractions and 3D stencil calculations on different processor microarchitectures, including Intel Knight Landing.

Current-voltage relationship in the auroral particle acceleration region

Directory of Open Access Journals (Sweden)

M. Morooka

2004-11-01

Full Text Available The current-voltage relationship in the auroral particle acceleration region has been studied statistically by the Akebono (EXOS-D satellite in terms of the charge carriers of the upward field-aligned current. The Akebono satellite often observed field-aligned currents which were significantly larger than the model value predicted by Knight (1973. We compared the upward field-aligned current estimated by three different methods, and found that low-energy electrons often play an important role as additional current carriers, together with the high-energy primary electrons which are expected from Knight's relation. Such additional currents have been observed especially at high and middle altitudes of the particle acceleration region. Some particular features of electron distribution functions, such as "cylindrical distribution functions" and "electron conics", have often been observed coinciding with the additional currents. They indicated time variability of the particle acceleration region. Therefore, we have concluded that the low-energy electrons within the "forbidden" region of electron phase space in the stationary model often contribute to charge carriers of the current because of the rapid time variability of the particle acceleration region. "Cylindrical distribution functions" are expected to be found below the time-varying potential difference. We statistically examined the locations of "cylindrical distribution function", and found that their altitudes are related to the location where the additional currents have been observed. This result is consistent with the idea that the low-energy electrons can also carry significant current when the acceleration region changes in time.

Foss, Nicolai Juul; Klein, Peter G.

Although they have developed very much in isolation from each other, we argue the theory ofentrepreneurship and the economic theory of the firm are closely related, and each has much tolearn from the other. In particular, the notion of entrepreneurship as judgment associated withFrank Knight...... and some Austrian school economists aligns naturally with the theory of the firm.In this perspective, the entrepreneur needs a firm, that is, a set of alienable assets he controls, tocarry out his function. We further show how this notion of judgment adds to the key themes inthe modern theory of the firm...

We have performed an ab initio molecular-dynamics simulation of liquid Ga at high temperature (1000 K). Our results are in good agreement with scattering data and with Knight-shift experiments. A remarkable feature of our findings is the coexistence in the liquid state of metallic and covalent characters. Covalency manifests itself in the appearance of very short-lived Ga-Ga bonds, which represent remnants in the liquid of the crystalline form [alpha]-Ga. We set up a two-fluid scheme which can be used for the analysis of fluids where metallic and covalent characters coexist. (orig.).

Ga and Pt NMR measurements have been carried out for two isomorphs compounds, UPtGa sub 5 and UNiGa sub 5 , which exhibit different magnetic structures below T sub N. Knight shift K measurements in the paramagnetic region are reported here. The transferred hyperfine coupling constants at Ga and Pt sites are determined. The temperature independent part K sub 0 of K, which probes the conduction electron polarization at the ligand site, has been successfully evaluated. A nearly identical conduction electron structure in the paramagnetic region is suggested for these two compounds. The origin of the different magnetic structures is discussed.

Many oilsands operators are investigating processes that will add value to oilsands tailings as well as mitigate their environmental footprint. Containing an estimated 10 per cent heavy minerals, nearly 6 cubic metres of tailings are created for every cubic metre of bitumen produced. This article presented details of a new process to extract titanium oxide (TiO{sub 2}) from oil sands tailings in order to produce the high quality TiO{sub 2} pigment used a whitener and opacifier for paper, plastics, paint and cosmetics. A licensing agreement has recently been reached between Western Oil Sands Inc. and Altair Nanotechnologies Inc. to test the patented process. The Altairnano Hydrochloride Pigment Process (AHP) is a package of technologies that includes 4 patents, trade secrets and expertise developed over a decade of research and development. The agreement is comprised of a 3 phase, 5 year program to evaluate, develop and commercialize the process, and includes the construction of a demonstration TiO{sub 2} production facility, as well as plans for a full-scale commercial facility. To date, Altairnano has processed bulk samples of oilsands tailings in various configurations to obtain mineral concentrates using the AHP process. The partnership is also considering a processing technology to demonstrate the feasibility of recycling hot water to recover residual asphaltene byproducts to produce a heavy mineral concentrate for further upgrading to zircon and rutile. 3 figs.

The exact solution of the one-dimensional vertical infiltration equation is deducted, when the hydraulic diffusivity is considered constant and the hydraulic conductivity is a combination of both a linear and quadratic functions of the soil water content. This quasi-linear solution includes as particular cases, both the classical solution known as linear soil and the Knight solution. The cumulative infiltrated water as a function of time provided by the quasi-linear solution has been compared with the cumulative infiltrated water obtained from the numerical solution of the Richards equation on three different soils of contrasting hydrodynamic properties. The good agreement between the two solutions has shown that the quasi-linear solution can be used on soils where the accepted hypothesis, on hydraulic diffusivity and hydraulic conductivity, for its deduction is not satisfied. [Spanish] Se deduce la solucion exacta de la ecuacion de la infiltracion unidimensional vertical cuando la difusividad hidraulica es considerada constante y la conductividad hidraulica es una combinacion de una funcion lineal y una cuadratica del contenido volumetrico de agua. Esta solucion cuasi-lineal de la infiltracion contiene, como casos particulares, la solucion clasica conocida como suelo lineal y la solucion de Knight. La lamina infiltrada acumulada en funcion del tiempo proporcionada por la solucion cuasi-lineal se ha comparado con la lamina infiltrada proporcionada por la solucion numerica de la ecuacion de Richards en tres suelos de propiedades hidrodinamicas contrastantes. El buen acuerdo entre las laminas infiltradas ha mostrado que la solucion cuasi-lineal puede utilizarse en suelos donde la difusividad y la conductividad hidraulicas no satisfacen los supuestos de la deduccion.

The case of a 50-year-old hidalgo who believed to be transformed into a knight-errant named Don Quijote is a megalomaniac systematized delusion of transformation of the self, a delusion of metamorphosis in reference to the patient's own identity. The outward projection of this syndrome produces some delusional misidentifications of others, things and animals and include elements of a persecutory delusion which increase the grandiosity of the self. At the same time the hidalgo was maniac with a pathway of bipolar disorder. The phenomenon of donquijotismo is described as the defence of wasted causes and Sancho Panza as an illiterate Sócrates.

Twisted condensates of quantized fields

Gallone, F.; Sparzani, A.; Ubertone, G.; Streater, R.F.

We construct some quasi-free pure states of free quantized fields in 1+1 dimensions, that are localized in the sense of Knight. We consider massless or massive Dirac fields forming a U(n), n >= 1, multiplet and subject it to a local gauge transformation. We also subject a doublet of massive Klein-Gordon fields to local SO(2) transformations. We find the conditions that the resulting automorphism is spatial in Fock space. In some cases the conditions turn out to require that certain parameters, identified as the winding numbers of the gauge, are integers. It is argued that this integer labels states of various charge.

Full Text Available The author documents and studies the artistic endowment of a chapel that belonged to knight Twenty-Four, Juan Serón Olarte, and his wife, Antonia de Verástegui, members of the Sevillian social elite, enriched thanks to the American trade. Between 1636 and 1638 several prominent artists such as Martín Moreno, Francisco de Ocampo and Baltasar Quintero, as well as the lesser known Juan de Palacios, took part in this project. The altarpiece in this chapel reflects the continuing influence of Italian Mannerism in Sevillian art of the early seventeenth century, a circumstance largely determined by the assimilation of diverse engraved sources.

Full Text Available In Fedor Mikhailovich Dostoevsky’s body of work (1821-1881 one can find more than thirty references to Don Quixote; while some of them allude to the novel of Don Quixote itself, other ones refer to Cervantes’ hero as an archetypal figure. Since decades ago, the Russian literary criticism has been interested in the Russian quixotism – including Dostoevsky’s work – and important studies on this subject have been published recently. This study follows Dostoevsky’s references on La Mancha’s Knight as an independent figure of Cervantes’ novel, and the different symbolism Don Quixote’s figure has had in both Russian people and Russian intelligentsia.

World War I advanced the development of aviation from the concept of flight to the use of aircraft on the battlefield. Fighter planes advanced technologically as the war progressed. Fighter pilot aces Francesco Baracca and Manfred von Richthofen (the Red Baron) were two of the most famous pilots of this time period. These courageous fighter aces skillfully maneuvered their SPAD and Albatros planes, respectively, while battling enemies and scoring aerial victories that contributed to the course of the war. The media thrilled the public with their depictions of the heroic feats of fighter pilots such as Baracca and the Red Baron. Despite their aerial prowess, both pilots would eventually be shot down in combat. Although the accounts of their deaths are debated, it is undeniable that both were victims of traumatic head injury.

Responses of Crop Pests and Natural Enemies to Wildflower Borders Depends on Functional Group.

Increased homogeneity of agricultural landscapes in the last century has led to a loss of biodiversity and ecosystem services. However, management practices such as wildflower borders offer supplementary resources to many beneficial arthropods. There is evidence that these borders can increase beneficial arthropod abundance, including natural enemies of many pests. However, this increase in local habitat diversity can also have effects on pest populations, and these effects are not well-studied. In this study, we investigated how wildflower borders affect both natural enemies and pests within an adjacent strawberry crop. Significantly more predators were captured in strawberry plantings with wildflower borders versus plantings without wildflowers, but this effect depended on sampling method. Overall, herbivore populations were lower in plots with a wildflower border; however, responses to wildflower borders varied across specific pest groups. Densities of Lygus lineolaris (Tarnished Plant Bug), a generalist pest, increased significantly in plots that had a border, while Stelidota geminata (Strawberry Sap Beetle) decreased in strawberry fields with a wildflower border. These results suggest that wildflower borders may support the control of some pest insects; however, if the pest is a generalist and can utilize the resources of the wildflower patch, their populations may increase within the crop.

Assessment Strategies for Implementing Ngss in K12 Earth System Science Classrooms

Several science education researchers have led assessment efforts that provide strategies particularly useful for evaluating the threedimensional learning that is central to NGSS (DeBarger, A. H., Penuel, W. R., Harris, C. J., Kennedy, C. K., 2016; Knight, A. M. & McNeill, K. L., 2015; McNeill, K.

One of the basic premises of these researchers is that, "Assessment is a practice of argument from evidence based on what students say, do, and write" and that "the classroom is the richest place to gather evidence of what students know (Penuel, W., 2016). The implementation of the NGSS in Earth System Science provides a unique opportunity for geoscience education researchers to study student learning and contribute to the development of this research as well as for geoscience educators to apply these approaches and strategies in their own work with K12 inservice and preservice educators.

Full Text Available This article offers a snapshot of the societal dynamics of individual countries around the world, integrated into a global view to provide the tourism and hospitality industry insight into potential customer needs and perceptions. The OPUS Reports on the Global Dynamics at the Dawn of 20...are published annually since 2006 in the Journal of Organisational and Social Dynamics in London. The researchers were interested in a metaphoric tour of the world's social dynamics over time as perceived from both the Systems psychodynamics and Positive psychology theoretical paradigms. The research methodology was qualitative using a case study approach where each of the six (2006- 2011 years' integrated hypotheses was studied as a separate case study. The six cases were integrated into new hypotheses reflecting how global social dynamics changed over the years. The findings were presented as hypotheses per individual country followed by an integrated global hypothesis. The three main emerging themes were framed as Identity, Hope and Love. Identity contains the sub-theme of Facelessness, described as the fragmentation of cultures, a loss of cultural identity and a search for shared social meaning. Hope embodies the theme Knight/s in shining armour which describes youth as saviours and Obama as saviour. The loss of Hope is illustrated by the sub-themes of the impotence of the older generation, pessimism, fear and the death of a way of life. Love consists of human connection described as affiliation, support and trust. The lack of Love consists of human alienation described as loneliness, aggression and violence. The findings of the study identify societal themes that can be operationalized in the tourism and hospitality industry through targeted offerings to provide in the unmet needs of society. In addition, training interventions to improve customer service and return on investment can be based on the findings of this research.

We present nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) measurements performed on single crystalline Ce2CoAl7Ge4 , a member of a recently discovered family of heavy fermion materials Ce2M Al7Ge4 (M =Co , Ir, Ni, or Pd). Previous measurements indicated a strong Kondo interaction as well as magnetic order below TM=1.8 K . Our NMR spectral measurements show that the Knight shift K is proportional to the bulk magnetic susceptibility χ at high temperatures. A clear Knight shift anomaly (K ¬∝χ ) is observed at coherence temperatures T*˜17.5 K for H0∥c ̂ and 10 K for H0∥a ̂ at the 59Co site, and T*˜12.5 K at the 27Al(3) site for H0∥a ̂ characteristic of the heavy fermion nature of this compound. At high temperatures, the 59Co NMR spin-lattice relaxation rate T1-1 is dominated by spin fluctuations of the 4 f local moments with a weak metallic background. The spin fluctuations probed by 59Co NMR are anisotropic and larger in the basal plane than in the c direction. Furthermore, we find (T1T K ) -1∝T-1 /2 at the 59Co site as expected for a Kondo system for T >T* and T >TK . 59Co NQR T1-1 measurements at low temperatures indicate slowing down of spin fluctuations above the magnetic ordering temperature TM˜1.8 K . A weak ferromagnetic character of fluctuations around q =0 is evidenced by an increase of χ T versus T above the magnetic ordering temperature. We also find good agreement between the observed and calculated electric field gradients at all observed sites.

We review our work done to optimize the staggered conjugate gradient (CG) algorithm in the MILC code for use with the Intel Knights Landing (KNL) architecture. KNL is the second gener- ation Intel Xeon Phi processor. It is capable of massive thread parallelism, data parallelism, and high on-board memory bandwidth and is being adopted in supercomputing centers for scientific research. The CG solver consumes the majority of time in production running, so we have spent most of our effort on it. We compare performance of an MPI+OpenMP baseline version of the MILC code with a version incorporating the QPhiX staggered CG solver, for both one-node and multi-node runs.

We report the results of 31 P NMR measurements on a Eu-based filled skutterudite phosphide EuRu 4 P 12 with ferromagnetic transition at T C =18K in order to investigate the magnetic properties from a microscopic point of view. The temperature dependence of the Knight shift is similar to that of the magnetic susceptibility. Also, the nuclear spin-lattice relaxation rate 1/T 1 is practically constant at higher temperatures above 50K due to the interaction of the 31 P nucleus with fluctuating local moments at the Eu 2+ sites, but decreases rapidly at low temperatures below T C , indicating the supression of the spin fluctuations by magnetic ordering

We report bulk superconductivity (SC) in Ca{sub 3}Ir{sub 4}Sn{sub 13} by means of {sup 119}Sn nuclear magnetic resonance (NMR) experiments. Two classical signatures of BCS superconductivity in spin-lattice relaxation rate (1/T{sub 1}), namely the Hebel–Slichter coherence peak just below the T{sub c}, and the exponential decay in the superconducting phase, are evident. The noticeable decrease of {sup 119}Sn Knight shift below T{sub c} indicates spin-singlet superconductivity. The temperature dependence of the spin-lattice relaxation rate {sup 119}(1/T{sub 1}) is convincingly described by the multigap isotropic superconducting gap. NMR experiments do not witness any sign of enhanced spin fluctuations.

Shared memory parallelization of PETSc-FUN3D, an unstructured tetrahedral mesh Euler code previously characterized for distributed memory Single Program, Multiple Data (SPMD) for thousands of nodes, is hybridized with shared memory Single Instruction, Multiple Data (SIMD) for hundreds of threads per node. We explore thread-level performance optimizations on state-of-the-art multi- and many-core Intel processors, including the second generation of Xeon Phi, Knights Landing (KNL). We study the performance on the KNL with different configurations of memory and cluster modes, with code optimizations to minimize indirect addressing and enhance the cache locality. The optimizations employed are expected to be of value other unstructured applications as many-core architecture evolves.

Infinite graphs in systematic biology, with an application to the species problem.

2013-06-01

We argue that C. Darwin and more recently W. Hennig worked at times under the simplifying assumption of an eternal biosphere. So motivated, we explicitly consider the consequences which follow mathematically from this assumption, and the infinite graphs it leads to. This assumption admits certain clusters of organisms which have some ideal theoretical properties of species, shining some light onto the species problem. We prove a dualization of a law of T. A. Knight and C. Darwin, and sketch a decomposition result involving the internodons of D. Kornet, J. Metz and H. Schellinx. A further goal of this paper is to respond to B. Sturmfels' question, "Can biology lead to new theorems?"

We present 27 Al NMR studies for a single crystal of the Np-based superconductor NpPd 5 Al 2 (T c =4.9K). We have observed a five-line 27 Al NMR spectrum with a center line and four satellite lines separated by first-order nuclear quadrupole splittings. The Knight shift clearly drops below T c . The temperature dependence of the 27 Al nuclear spin-lattice relaxation rate shows no coherence peak below T c , indicating that NpPd 5 Al 2 is an unconventional superconductor with an anisotropic gap. The analysis of the present NMR data provides evidence for strong-coupling d-wave superconductivity in NpPd 5 Al 2 .

The high-tech building for CAMD has been designed by TECH-IV of Baton Rouge with engineering support from Lester B. Knight and Associates of Chicago. The storage ring has been optimized for X-ray lithography. The procedures developed at CAMD for printing integrated circuits may well be of significant importance to US competitiveness in semiconductor and related industries. However, the spectral range of the ring also supports scientific and engineering activities in several other areas. (orig.)

2013 update on sea otter studies to assess recovery from the 1989 Exxon Valdez oil spill, Prince William Sound, Alaska

On March 24, 1989, the tanker vessel Exxon Valdez ran aground in Prince William Sound, Alaska, spilling an estimated 42 million liters of Prudhoe Bay crude oil. Oil spread in a southwesterly direction and was deposited on shores and waters in western Prince William Sound (WPWS). The sea otter (Enhydra lutris) was one of more than 20 nearshore species considered to have been injured by the spill. Since 1989, the U.S. Geological Survey has led a research program to evaluate effects of the spill on sea otters and assess progress toward recovery, as defined by demographic and biochemical indicators. Here, we provide an update on the status of sea otter populations in WPWS, presenting findings through 2013. To assess recovery based on demographic indicators, we used aerial surveys to estimate abundance and annual collections of sea otter carcasses to evaluate patterns in ages-at-death. To assess recovery based on biochemical indicators, we quantified transcription rates for a suite of genes selected as potential indicators of oil exposure in sea otters based on laboratory studies of a related species, the mink (Mustela vison). In our most recent assessment of sea otter recovery, which incorporated results from a subset of studies through 2009, we concluded that recovery of sea otters in WPWS was underway. This conclusion was based on increasing abundance throughout WPWS, including increasing numbers at northern Knight Island, an area that was heavily oiled in 1989 and where the local sea otter population had previously shown protracted injury and lack of recovery. However, we did not conclude that the WPWS sea otter population had fully recovered, due to indications of continuing reduced survival and exposure to lingering oil in sea otters at Knight Island, at least through 2009. Based on data available through 2013, we now conclude that the status of sea otters—at all spatial scales within WPWS—is consistent with the designation of recovery from the spill as

"Knight in shining armour" or "Frankenstein's creation"? The coverage of synthetic biology in German-language media.

Although still a side issue in the German-language media, attention towards synthetic biology has risen clearly during the last years, in line with the first applications being presented. This paper presents findings from a content analysis of synthetic biology coverage in German-language media over the years 2004-2009. In the media, synthetic biology is not clearly separated from gene technology. News value is attributed to established categories such as persons and events. Many metaphors and analogies used in describing gene technology can also be found in the coverage of synthetic biology; however, engineering metaphors are more prominent. In addition, playfulness constitutes an aspect rarely found in genetic engineering coverage. Overall, the picture emerging is ambivalent, which leaves prospects for the further development of public debate ambiguous.

Full Text Available By the Late Middle Ages, mounted troops - cavalry in the form of knights - are established as the dominant battlefield arm in North-Western Europe. This paper considers the development of cavalry after the Germanic Barbarian Successor Kingdoms such as the Visigoths in Spain or the Carolingian Franks emerged from Roman Late Antiquity and their encounters with Islam, as with the Moors in Iberia or the Saracens (Arabs and Turks during the Crusades, since an important part of literature ascribes advances in European horse breeding and horsemanship to Arab influence. Special attention is paid to information about horse types or breeds, conformation, tactics - fighting with lance and bow - and training. Genetic studies and the archaeological record are incorporated to test the literary tradition.

"3"1P Nuclear Magnetic Resonance of Charge-Density-Wave Transition in a Single Crystal of RuP

Fan Guo-Zhi; Luo Jian-Lin; Chen Rong-Yan; Wang Nan-Lin

2015-01-01

We perform "3"1P nuclear magnetic resonance (NMR) measurements on a single crystal of RuP. The anomalies in resistivity at about T_A = 270 K and T_B = 330 K indicate that two phase transitions occur. The line shape of "3"1P NMR spectra in different temperature ranges is attributed to the charge density distribution. The Knight shift and spin-lattice relaxation rate 1/T_1T are measured from 10 K to 300 K. At about T_A = 270 K, they both decrease abruptly with the temperature reduction, which reveals the gap-opening behavior. Well below T_A, they act like the case of normal metal. Charge-density-wave phase transition is proposed to interpret the transition occurring at about T_A. (paper)

Full Text Available In 2011 a discovery was made at the Department of Prints and Drawings of the National Museum in Warsaw - a drawing hitherto described as a Kneeling knight by an anonymous seventeenth-century artist, turned out to be Joan of Arc, a sketch well-known to art historians studying the oeuvre of Peter Paul Rubens, although thought to be lost during the Second World War. The drawing, until now known only through the black and white photograph, could be thoroughly analysed for the first time. In the context of information thus obtained, the historical context of creating the sketch transpired as an equally important matter, including the hypothetical role that may have been played in its creation by Nicolas-Claude Fabri de Peiresc.

Modeling the performance of scientific applications on emerging hardware plays a central role in achieving extreme-scale computing goals. Analytical models that capture the interaction between applications and hardware characteristics are attractive because even a reasonably accurate model can be useful for performance tuning before the hardware is made available. In this paper, we develop a hardware model for Intel’s second-generation Xeon Phi architecture code-named Knights Landing (KNL) for the SKOPE framework. We validate the KNL hardware model by projecting the performance of mini-benchmarks and application kernels. The results show that our KNL model can project the performance with prediction errors of 10% to 20%. The hardware model also provides informative recommendations for code transformations and tuning.

Students presenting with syncope and/or seizure occur occasionally in the school setting. Several studies have shown that seizures as well as respiratory distress are the most common medical emergencies that prompt school nurses and staff to contact emergency medical services (EMS) to transport students to the closest emergency department (Knight 1999, Olympia 2005). It is important to develop a differential diagnosis for syncope, to initiate stabilization of the student with life-threatening symptoms, and to triage these students to an appropriate level of care (back to the classroom, home with their guardian with follow-up at their primary health care provider's office, or directly to the closest emergency department via EMS). This article describes the initial assessment and management of two students presenting after syncopal events.

Full Text Available In consonance with masculinist paradigms present in Arthurian romances, the knight is, generally, the doer, the agent, or the acting partner while the lady is fragile, passive and, therefore, does not engage in any action. This gendered reading, however, cannot be applied to the chivalresque novel Historia de los invictos y magnánimos caballeros don Cristalián de España, Príncipe de Trapisonda, y del Infante Lucescanio su hermano, hijos del famosísimo Emperador Lindedel de Trapisonda, published by Beatriz Bernal in Valladolid in 1545. This article explores the strategies used by the autor of this text to effect a refashioning of the chivalresque genre and to defy its generic roles.

Superconductivity and NMR investigations of amorphous Be-Nb-Zr and Be-Mo-Zr alloys

9 Be NMR investigations and measurements of the superconducting properties and the resistivity are reported for amorphous Besub(32.5)Nbsub(x)Zrsub(67.5-x) and Besub(32.5)Mosub(x)Zrsub(67.5-x) alloys (x = 2.5; 5; 7). Line width analysis suggests an enlarged Nb concentration around the Be sites for the Be-Nb-Zr alloys. Comparing the two types of alloys the Knight shifts are of the same order of magnitude whereas the Tsub(c) and Bsub(c) 2 (0) values are slightly smaller than for the Nb alloys. For Be-Nb-Zr Tsub(c) and K increases with the Nb content. The results are discussed in connection with the density of states N(Esub(F)). (orig.)

2008-01-01

In order to investigate the heavy-fermion like behavior of amorphous alloy Ce x Mn 100-x , the NMR measurements of 55 Mn (I=5/2 ) in Ce 65 Mn 35 have been carried out from 4.2 to 270 K using powdered sample. A broadened NMR spectrum containing five NQR lines split due to NQR interaction is observed. Quadrupole coupling constant 3e 2 Qq/2I(2I-1)h is gradually changed from about 1.8 MHz at 4.2 K to about 1.6 MHz at 270 K. Temperature dependence of the line width is expressed in the Curie-Weiss law with θ p =-10.5K. The value of Knight shift would be almost constant from 4.2 to 270 K

First order magnetic transition in single crystal CaFe2As2 detected by 75As NMR

We report {sup 75}As Nuclear Magnetic Resonance data in a single crystal of CaFe{sub 2}As{sub 2}. The Knight shift, the electric field gradient, and the spin lattice relaxation rate are strongly temperature dependent in the paramagnetic state, and change discontinuously at the structural transition temperature, T{sub S} = T{sub N} = 167 K. Immediately below, the NMR spectra reveal an internal field at the As site associated with the presence of a commensurate magnetic order. These results indicate that the structural and magnetic transitions in CaFe{sub 2}As{sub 2} are first order and strongly coupled, and that the electron density in the FeAs plane is highly sensitive to the out-of-plane structure.

Some history and use of the random positioning machine, RPM, in gravity related research

Science.gov (United States)

van Loon, Jack J. W. A.

The first experiments using machines and instruments to manipulate gravity and thus learn about its impact to this force onto living systems were performed by Sir Thomas Andrew Knight in 1806, exactly two centuries ago. What have we learned from these experiments and in particular what have we learned about the use of instruments to reveal the impact of gravity and rotation on plants and other living systems? In this essay I want to go into the use of instruments in gravity related research with emphases on the Random Positioning Machine, RPM. Going from water wheel via clinostat to RPM, we will address the usefulness and possible working principles of these hypergravity and mostly called microgravity, or better, micro-weight simulation techniques.

New Maps for Old: a Topological Approach to "the Faerie Queene" and Shakespeare's History Plays

Science.gov (United States)

Graney, Kathleen M.

1994-01-01

When Nicholas Copernicus published De revolutionibus in 1543, his announced discoveries both displaced humankind from its former place at the center of the universe and enlarged the boundaries of that universe beyond anything that had been imagined before. These discoveries evoked in men and women of the late-sixteenth century a new consciousness of both cosmic space and of psychological spaces within themselves, spaces for self-definition made available by the breakdown of the traditional, hierarchical world view. This re-vision of space is evident in almost every aspect of the culture of Elizabethan England, from its science and art to the accounts of New World voyagers. In the works of Edmund Spenser and William Shakespeare, this spatial awareness manifests itself "topologically" --that is, in the relationship between places in their epic and dramatic works that can be identified as "inside" or "outside" and in the kinds of actions associated with each place. In Books One and Two of The Faerie Queene Spenser uses space both topographically and topologically. He maps the journeys of his knights through Fairyland by means of references to allegorical structures and features of the mythical landscape. At the same time, he contrasts inside spaces, where the knights struggle psychologically to define themselves in terms of certain moral virtues, and outside spaces, where that "self" intersects with Spenser's myth of English history. In his earliest chronicle plays of the 1580s and '90s Shakespeare also depicts English history topographically, as a series of epic confrontations enacted in outside, public spaces bearing familiar place -names. With Richard III, however, he begins to dramatize that history as related to moments of self-discovery achieved by the central character within the privacy of inside spaces and involving some conflict between the values of public and private life. Unlike Spenser, whose characters ultimately define themselves in terms of some value

Effective mitigation of debris flows at Lemon Dam, La Plata County, Colorado

Science.gov (United States)

deWolfe, V.G.; Santi, P.M.; Ey, J.; Gartner, J.E.

2008-01-01

To reduce the hazards from debris flows in drainage basins burned by wildfire, erosion control measures such as construction of check dams, installation of log erosion barriers (LEBs), and spreading of straw mulch and seed are common practice. After the 2002 Missionary Ridge Fire in southwest Colorado, these measures were implemented at Knight Canyon above Lemon Dam to protect the intake structures of the dam from being filled with sediment. Hillslope erosion protection measures included LEBs at concentrations of 220-620/ha (200-600% of typical densities), straw mulch was hand spread at concentrations up to 5.6??metric tons/hectare (125% of typical densities), and seeds were hand spread at 67-84??kg/ha (150% of typical values). The mulch was carefully crimped into the soil to keep it in place. In addition, 13 check dams and 3 debris racks were installed in the main drainage channel of the basin. The technical literature shows that each mitigation method working alone, or improperly constructed or applied, was inconsistent in its ability to reduce erosion and sedimentation. At Lemon Dam, however, these methods were effective in virtually eliminating sedimentation into the reservoir, which can be attributed to a number of factors: the density of application of each mitigation method, the enhancement of methods working in concert, the quality of installation, and rehabilitation of mitigation features to extend their useful life. The check dams effectively trapped the sediment mobilized during rainstorms, and only a few cubic meters of debris traveled downchannel, where it was intercepted by debris racks. Using a debris volume-prediction model developed for use in burned basins in the Western U.S., recorded rainfall events following the Missionary Ridge Fire should have produced a debris flow of approximately 10,000??m3 at Knight Canyon. The mitigation measures, therefore, reduced the debris volume by several orders of magnitude. For comparison, rainstorm

Quasiparticle Scattering off Defects and Possible Bound States in Charge-Ordered YBa_{2}Cu_{3}O_{y}.

We report the NMR observation of a skewed distribution of ^{17}O Knight shifts when a magnetic field quenches superconductivity and induces long-range charge-density-wave (CDW) order in YBa_{2}Cu_{3}O_{y}. This distribution is explained by an inhomogeneous pattern of the local density of states N(E_{F}) arising from quasiparticle scattering off, yet unidentified, defects in the CDW state. We argue that the effect is most likely related to the formation of quasiparticle bound states, as is known to occur, under specific circumstances, in some metals and superconductors (but not in the CDW state, in general, except for very few cases in 1D materials). These observations should provide insight into the microscopic nature of the CDW, especially regarding the reconstructed band structure and the sensitivity to disorder.

Impurity-induced moments in underdoped cuprates

Khaliullin, G.; Kilian, R.; Krivenko, S.; Fulde, P.

1997-01-01

We examine the effect of a nonmagnetic impurity in a two-dimensional spin liquid in the spin-gap phase, employing a drone-fermion representation of spin-1/2 operators. The properties of the local moment induced in the vicinity of the impurity are investigated and an expression for the nuclear-magnetic-resonance Knight shift is derived, which we compare with experimental results. Introducing a second impurity into the spin liquid an antiferromagnetic interaction between the moments is found when the two impurities are located on different sublattices. The presence of many impurities leads to a screening of this interaction as is shown by means of a coherent-potential approximation. Further, the Kondo screening of an impurity-induced local spin by charge carriers is discussed. copyright 1997 The American Physical Society

Hyperfine interactions measured by nuclear orientation technique

1982-01-01

This report concerns the use of hyperfine interaction to magnetism measurements and to the determination of the nuclear structure of Terbium isotopes by the low temperature nuclear orientation technique. In the first part we show that the rhodium atom does not support any localized moment in the chromium matrix. The hyperfine magnetic field at the rhodium nuclear site follows the Overhauser distribution, and the external applied magnetic field supports a negative Knight shift of 16%. In the second part we consider the structure of neutron deficient Terbium isotopes. We introduce a coherent way of evaluation and elaborate a new nuclear thermometer. The magnetic moments allows to strike on the studied states configuration. The analysis of our results shows a decrease of the nuclear deformation for the lighter isotopes [fr

Optimizing fusion PIC code performance at scale on Cori Phase 2

In this paper we present the results of optimizing the performance of the gyrokinetic full-f fusion PIC code XGC1 on the Cori Phase Two Knights Landing system. The code has undergone substantial development to enable the use of vector instructions in its most expensive kernels within the NERSC Exascale Science Applications Program. We study the single-node performance of the code on an absolute scale using the roofline methodology to guide optimization efforts. We have obtained 2x speedups in single node performance due to enabling vectorization and performing memory layout optimizations. On multiple nodes, the code is shown to scale well up to 4000 nodes, near half the size of the machine. We discuss some communication bottlenecks that were identified and resolved during the work.

Nutrient Deprivation Induces Property Variations in Spider Gluey Silk

Understanding the mechanisms facilitating property variability in biological adhesives may promote biomimetic innovations. Spider gluey silks such as the spiral threads in orb webs and the gumfoot threads in cobwebs, both of which comprise of an axial thread coated by glue, are biological adhesives that have variable physical and chemical properties. Studies show that the physical and chemical properties of orb web gluey threads change when spiders are deprived of food. It is, however, unknown whether gumfoot threads undergo similar property variations when under nutritional stress. Here we tested whether protein deprivation induces similar variations in spiral and gumfoot thread morphology and stickiness. We manipulated protein intake for the orb web spider Nephila clavipes and the cobweb spider Latrodectus hesperus and measured the diameter, glue droplet volume, number of droplets per mm, axial thread width, thread stickiness and adhesive energy of their gluey silks. We found that the gluey silks of both species were stickier when the spiders were deprived of protein than when the spiders were fed protein. In N. clavipes a concomitant increase in glue droplet volume was found. Load-extension curves showed that protein deprivation induced glue property variations independent of the axial thread extensions in both species. We predicted that changes in salt composition of the glues were primarily responsible for the changes in stickiness of the silks, although changes in axial thread properties might also contribute. We, additionally, showed that N. clavipes' glue changes color under protein deprivation, probably as a consequence of changes to its biochemical composition. PMID:24523902

Building-Up of a DNA Barcode Library for True Bugs (Insecta: Hemiptera: Heteroptera) of Germany Reveals Taxonomic Uncertainties and Surprises

During the last few years, DNA barcoding has become an efficient method for the identification of species. In the case of insects, most published DNA barcoding studies focus on species of the Ephemeroptera, Trichoptera, Hymenoptera and especially Lepidoptera. In this study we test the efficiency of DNA barcoding for true bugs (Hemiptera: Heteroptera), an ecological and economical highly important as well as morphologically diverse insect taxon. As part of our study we analyzed DNA barcodes for 1742 specimens of 457 species, comprising 39 families of the Heteroptera. We found low nucleotide distances with a minimum pairwise K2P distance 2.2% were detected for 16 traditionally recognized and valid species. With a successful identification rate of 91.5% (418 species) our study emphasizes the use of DNA barcodes for the identification of true bugs and represents an important step in building-up a comprehensive barcode library for true bugs in Germany and Central Europe as well. Our study also highlights the urgent necessity of taxonomic revisions for various taxa of the Heteroptera, with a special focus on various species of the Miridae. In this context we found evidence for on-going hybridization events within various taxonomically challenging genera (e.g. Nabis Latreille, 1802 (Nabidae), Lygus Hahn, 1833 (Miridae), Phytocoris Fallén, 1814 (Miridae)) as well as the putative existence of cryptic species (e.g. Aneurus avenius (Duffour, 1833) (Aradidae) or Orius niger (Wolff, 1811) (Anthocoridae)).

Sleep and sleep disorders in Don Quixote.

Science.gov (United States)

Iranzo, Alex; Santamaria, Joan; de Riquer, Martín

2004-01-01

In Don Quijote de la Mancha, Miguel de Cervantes presents Don Quixote as an amazing character of the 17th century who suffers from delusions and illusions, believing himself to be a medieval knight errant. Besides this neuropsychiatric condition, Cervantes included masterful descriptions of several sleep disorders such as insomnia, sleep deprivation, disruptive loud snoring and rapid eye movement sleep behaviour disorder. In addition, he described the occurrence of physiological, vivid dreams and habitual, post-prandial sleepiness--the siesta. Cervantes' concept of sleep as a passive state where all cerebral activities are almost absent is in conflict with his description of abnormal behaviours during sleep and vivid, fantastic dreams. His concept of sleep was shared by his contemporary, Shakespeare, and could have been influenced by the reading of the classical Spanish book of psychiatry Examen de Ingenios (1575).

Theory of exotic superconductivity and normal states of heavy electron and high temperature superconductivity materials. Progress report, February 15, 1994--February 14, 1995

International Nuclear Information System (INIS)

Cox, D.L.

1995-01-01

This is a progress report for the DOE project covering the period 2/15/94 to 2/14/95. The PI had a fruitful sabbatical during this period, and had some important new results, particularly in the area of new phenomenology for heavy fermion superconductivity. Significant new research accomplishments are in the area of odd-in-time-reversal pairing states/staggered superconductivity, the two-channel Kondo lattice, and a general model for Ce impurities which admits one-, two-, and three-channel Kondo effects. Papers submitted touch on these areas: staggered superconductivity - a new phenomenology for UPt 3 ; theory of the two-channel Kondo lattice in infinite dimensions; general model of a Ce 3+ impurity. Other work was done in the areas: Knight shift in heavy fermion alloys and compounds; symmetry analysis of singular pairing correlations for the two-channel Kondo impurity model

[The last melancholia of Alonso Quijano, the Righteous].

Chiappo, L

1994-03-01

In Cervantes' immortal novel, "Don Quixote" is the nom de guerre that Alonso Quijano--a honest Spanish yeoman nicknamed "The Upright One"--adopts under the spell of insanity that has lured him into being a knight rider. A psycho-spiritual analysis of Don Quixote's return to mental health is presented, covering the time-span between Don Quixote's coming back to this native village and his last days. By way of a "historical diagnosis", the author proposes some clinical explanations: Goodman Quijano's last illness might have been a plasmodium falciparum-caused malaria; malaria, however did not contribute to reinstate soundmindedness (as per Wagner von Jauregg's therapeutic criteria, for example). Goodman Quijano's last fit of melancholy disclosed contempu mundi in him, a renunciation giving way to a joyful lucidity--in other words, a psychological awakening to a sublime conscience level of genuine spiritual characteristics.

THE RISE AND FALL OF THE GREENE DOCTRINE: THE SHERMAN ACT, HOWELL JACKSON, AND THE INTERPRETATION OF “INTERSTATE COMMERCE”, 1890 — 1941

Full Text Available This paper deals with the evolution of the judicial interpretation of the term“ interstate commerce” beginning with the enactment the Sherman Anti-Trust Act of 1890 and concluding with the Supreme Court’s US. v. Darby decision some 51 years later. As may be recalled, the Fuller Court’s 1895 ruling in E.C. Knight all but destroyed Sherman and allowed most corporate monopolies free reign going into the early twentieth century. Even after Sherman’s revival in Northern Securities, however, the Court’s narrow interpretation of “interstate commerce” continued to effectively thwart federal attempts at economic regulation for the next half century. This paper examines the formulation of the so-called “Greene Doctrine” and its author, future Supreme Court Justice Howell Edmunds Jackson as well as their ultimate impact on American constitutional and economic history.

Response: Freedom from Pain as a Rawlsian Primary Good.

Science.gov (United States)

James Roberts, Adam

2016-11-01

In a recent article in this journal, Carl Knight and Andreas Albertsen argue that Rawlsian theories of distributive justice as applied to health and healthcare fail to accommodate both palliative care and the desirability of less painful treatments. The asserted Rawlsian focus on opportunities or capacities, as exemplified in Normal Daniels' developments of John Rawls' theory, results in a normative account of healthcare which is at best only indirectly sensitive to pain and so unable to account for the value of efforts of which the sole purpose is pain reduction. I argue that, far from undermining the Rawlsian project and its application to problems of health, what the authors' argument at most amounts to is a compelling case for the inclusion of freedom from physical pain within its index of primary goods. © 2016 John Wiley & Sons Ltd.

Read on for an update from a few of the latest studies.What is Oumuamua?In lateOctober2017, the discovery of minor planet 1I/Oumuamua was announced. This body which researchers first labeled asa comet and later revised to an asteroid had just zipped around the Sun and was already in the process of speeding away whenwe trained our telescopes on it. Its trajectory, however, marked it as being a visitor from outside our solar system: the first knownvisitorof its kind.Since Oumuamuasdiscovery, scientists have been gathering as many observations of this bodyas possible before it vanishes into the distance. Simultaneously, theorists have leapt at the opportunity to explain its presence and the implications its passage has on our understanding of our surroundings. Here we present just a few of the latest studies that have been published on this first detected interstellar asteroid including several timelystudies published in our new journal, Research Notes of the AAS.The galactic velocity of Oumuamua does not coincide with any of the nearest stars to us. [Mamajek 2018]Where Did Oumuamua Come From?Are we sure Oumuamua didnt originate in our solar system andget scattered into a weird orbit? Jason Wright (The Pennsylvania State University) demonstrates via a series of calculations that no known solar system body could have scattered Oumuamua onto its current orbit nor could any stillunknown object bound to our solar system.Eric Mamajek (Caltech and University of Rochester) showsthat thekinematics of Oumuamua areconsistent with what we might expect of interstellar field objects, though he argues that its kinematics suggest its unlikely to have originated from many of the neareststellar systems.What AreOumuamuas Properties?Oumuamuas light curve.

The dark knight : Sir Thomas Tait and the rise and fall of New Brunswick's famous coalfields

Energy Technology Data Exchange (ETDEWEB)

Woodford, G.

2010-03-15

Industrial coal mining in New Brunswick began in the early 1900s. In 1913, a former Canadian Pacific Railway (CPR) manager, Sir Thomas Tait, learned of underexploited coalfields around Grand Lake and negotiated the best coal assets from locals. He used his CPR connections to secure a large government grant to finish an important 50-kilometre railway link between Minto and Fredericton. He kept the coal assets for himself and formed the Minto Coal Company and landed 2 prime contracts to supply coal to a nearby cotton mill and to CPR. This article highlighted Tait's disreputable approach to labour relations. Despite lucrative contracts to Minto Coal during World War 1, Tait did not share the profits with his miners. This coal mining period in New Brunswick was characterized by union busting, evictions from dire company housing, arbitrary pay cuts, strikes and increasingly unsafe conditions in the mines. Two royal commissions were called to look into matters, but the province had no legislation to enforce their many recommendations. However, the government finally passed legislation when in 1932, 5 people died trying to rescue boys who were poisoned while playing in an abandoned mine shaft. That same year, 14 miners were disabled and 2 men killed in accidents at Minto Coal. Legislation forced mines to reduce work hours and improve safety. Women and children were barred from mining. When Tait refused to reduce work hours the miners went on strike again. After a critical situation in 1937 when 1000 miner and 11 colliers walked out, things gradually improved for both the miners and mine owners. New technology in the 1940s led to greater production, safety and profits. In 1944, Minto Coal donated land and money to build the town's first hospital. Credit for this philanthropy did not go to Thomas Tait, who died in 1940.

Full Text Available RESUMEN: La orden del Santo Sepulcro nace en Jerusalén el año 1099, poco después de que fuera conquistada la ciudad por Godofredo de Bouillon durante la Primera Cruzada. Este caudillo borgoñón, tras ser aceptado como protector del Santo Sepulcro, organizó un servicio religioso con canónigos del clero regular, a cuyo frente nombró a un prior. Creó asimismo una guardia de honor con caballeros cruzados que prestaron voto de obediencia con el juramento de consagrar su vida a la defensa del Santo Sepulcro.La orden del Santo Sepulcro se distinguió por unir el carácter militar de sus caballeros con el religioso de sus canónigos. Los caballeros, bajo la obediencia del patriarca latino de Jerusalén, prior general de la orden, concretaron su organización durante el reinado de Balduino I (1100-1118.Tras la caída de Sanjuan de Acre (1291, los caballeros y canónigos de la orden se dispersaron por los reinos europeos que manteníano prioratos. El papa Inocencio VIII en el año 1489 incorporó la orden con todos sus bienes a los Hospitalarios de San Juan, pero siete años después el papa Alejandro VI anuló dicha decisión.A partir de entonces surgieron diversas iniciativas para revitalizar la orden, especialmente en el año 1558 en el que se ofreció a Felipe II de España el Gran Maestrazgo de la orden. La última tentativa se produce en 1818, al autoproclamarse Luis XVIII de Francia soberano y protector del Santo Sepulcro. En el año 1847, resurge la orden cuando el papa Pío IX restaura el Patriarcado Latino de Jerusalén y concede al patriarca el Gran Maestrazgo de la orden.ABSTRACT: In 1099, after the capture of Jerusalem, and the establishment of the Crusader Kingdom, there was a distinct corps of professed Knights dedicated to the defence of the newly won territory.

The Global Nested Air Quality Prediction Modeling System (GNAQPMS) is the global version of the Nested Air Quality Prediction Modeling System (NAQPMS), which is a multi-scale chemical transport model used for air quality forecast and atmospheric environmental research. In this study, we present the porting and optimisation of GNAQPMS on a second-generation Intel Xeon Phi processor, codenamed Knights Landing (KNL). Compared with the first-generation Xeon Phi coprocessor (codenamed Knights Corner, KNC), KNL has many new hardware features such as a bootable processor, high-performance in-package memory and ISA compatibility with Intel Xeon processors. In particular, we describe the five optimisations we applied to the key modules of GNAQPMS, including the CBM-Z gas-phase chemistry, advection, convection and wet deposition modules. These optimisations work well on both the KNL 7250 processor and the Intel Xeon E5-2697 V4 processor. They include (1) updating the pure Message Passing Interface (MPI) parallel mode to the hybrid parallel mode with MPI and OpenMP in the emission, advection, convection and gas-phase chemistry modules; (2) fully employing the 512 bit wide vector processing units (VPUs) on the KNL platform; (3) reducing unnecessary memory access to improve cache efficiency; (4) reducing the thread local storage (TLS) in the CBM-Z gas-phase chemistry module to improve its OpenMP performance; and (5) changing the global communication from writing/reading interface files to MPI functions to improve the performance and the parallel scalability. These optimisations greatly improved the GNAQPMS performance. The same optimisations also work well for the Intel Xeon Broadwell processor, specifically E5-2697 v4. Compared with the baseline version of GNAQPMS, the optimised version was 3.51 × faster on KNL and 2.77 × faster on the CPU. Moreover, the optimised version ran at 26 % lower average power on KNL than on the CPU. With the combined performance and energy

Cabalgando a la ventura ha de velar sobre sí para no apartarse un ápice de los ideales que se ha autoimpuestoThe essay focuses on Don Quijote in the perspective of the intense and variegated exercise of the will that characterizes the knight-errant. Cervantes’ protagonist has decided for himself to change his life and give himself a new one freely chosen. Without hesitation, he makes ready to emerge in the world as other than he used to be. And, in fact, his voluntary determination is so strong that nothing nor any body can affect his free decision. The sense of his sudden conversión leads him to fight against different evils and their unpunished agents. His decision to overcome the enemies in accordance with the chivalry model, includes also the winning of the everlasting fame that comes to the wandering knights in his favorite novels. The election of this model of existence obliges him to adopt all the rules of living and morality proper to the chivalric code, overcoming thus his own will. Riding haphazard will be his sole protection to prevent the least slipping in the high ideals

This study provides a detailed secondary structural characterization of major ampullate dragline silk from Latrodectus hesperus (black widow) spiders. X-ray diffraction results show that the structure of black widow major ampullate silk fibers is comprised of stacked β-sheet nanocrystallites oriented parallel to the fiber axis and an amorphous region with oriented (anisotropic) and isotropic components. The combination of two-dimensional (2D) 13C-13C through-space and through-bond solid-state NMR experiments provide chemical shifts that are used to determine detailed information about amino acid motif secondary structure in black widow spider dragline silk. Individual amino acids are incorporated into different repetitive motifs that make up the majority of this protein-based biopolymer. From the solid-state NMR measurements, we assign distinct secondary conformations to each repetitive amino acid motif and hence to the amino acids that make up the motifs. Specifically, alanine is incorporated in β-sheet (poly(Alan) and poly(Gly-Ala)), 31-helix (poly(Gly-Gly-Xaa), and α-helix (poly(Gln-Gln-Ala-Tyr)) components. Glycine is determined to be in β-sheet (poly(Gly-Ala)) and 31-helical (poly(Gly-Gly-Xaa)) regions, while serine is present in β-sheet (poly(Gly-Ala-Ser)), 31-helix (poly(Gly-Gly-Ser)), and β-turn (poly(Gly-Pro-Ser)) structures. These various motif-specific secondary structural elements are quantitatively correlated to the primary amino acid sequence of major ampullate spidroin 1 and 2 (MaSp1 and MaSp2) and are shown to form a self-consistent model for black widow dragline silk.

To increase knowledge about the presence of endangered species and their habitat at the LANL, 3D/Environmental Services, Inc. conducted a mist net survey for bats on Laboratory lands. In addition to documenting the presence of threatened and endangered species, this survey was conducted to gain more knowledge about the diversity and distribution of the bat fauna existing on the Laboratory. There are 25 species of bats found in New Mexico, about 16 of which are likely to occur in the region of the Laboratory. Of particular interest was documentation of the presence of the spotted bat, Euderma maculatum. The spotted bat is listed as Endangered, Group 2 by the State of New Mexico, and is a Federal Candidate for listing as endangered. As such, conservation of this species and its habitat should be a management priority on the Laboratory. A total of 94 bats were captured in 16 net nights, between 30 June and 05 July 1992.

Are affective events richly recollected or simply familiar? The experience and process of recognizing feelings past.

Science.gov (United States)

Ochsner, K N

2000-06-01

The author used the remember/know paradigm and the dual process recognition model of A. P. Yonelinas, N. E. A. Kroll, I. Dobbins, M. Lazzara, and R. T. Knight (1998) to study the states of awareness accompanying recognition of affective images and the processes of recollection and familiarity that may underlie them. Results from all experiments showed that (a) negative stimuli tended to be remembered, whereas positive stimuli tended to be known; (b) recollection, but not familiarity, was boosted for negative or highly arousing and, to a lesser extent, positive stimuli; and (c) across experiments, variations in depth of encoding did not influence these patterns. These data suggest that greater recollection for affective events leads them to be more richly experienced in memory, and they are consistent with the idea that the states of remembering and knowing are experientially exclusive, whereas the processes underlying them are functionally independent.

To investigate dental erosion among 12-14 year old Sudanese school children and evaluate the associated risk factors. Cross sectional survey in secondary schools in Khartoum city, Sudan. A sample of 157 school children was obtained from both private and public schools. Erosion on the labial and palatal surfaces of maxillary incisors was measured by criterion based on the Smith and Knight Tooth Wear Index. Dietary intake and other related factors were assessed using a questionnaire. The overall erosion prevalence in this group was 66.9%, of which 45.2% was mild and 21.7% was moderate erosion. A strong association was found between erosion and private schooling (higher socioeconomic groups), carbonated drinks, herbal hibiscus drink and traditional acidic food consumption. There was a high prevalence of dental erosion among Sudanese school children which was mild to moderate in severity and was strongly associated with acidic dietary intake

Henry was an eyewitness, even if surely biased...... chronicle examined in this article is the Chronicon terre Prussie. This chronicle, authored by a Teutonic Knight named Peter of Dusburg and written c.1326, relates the arrival and history of the Teutonic Order in Prussia from c.1230, also covering the initial submission of the Prussian pagans to Christian......, creating a struggle for autonomy and dominance. The two chronicles made considerable use of Scripture, albeit in different ways. This article investigates the uses of the Bible in both chronicles with a special eye to how ideas of providential history — that is the role assigned by the authors...

Risk and Management Control: A Partial Least Square Modelling Approach

DEFF Research Database (Denmark)

Nielsen, Steen; Pontoppidan, Iens Christian

Risk and economic theory goes many year back (e.g. to Keynes & Knight 1921) and risk/uncertainty belong to one of the explanations for the existence of the firm (Coarse, 1937). The present financial crisis going on in the past years have re-accentuated risk and the need of coherence...... and interrelations between risk and areas within management accounting. The idea is that management accounting should be able to conduct a valid feed forward but also predictions for decision making including risk. This study reports the test of a theoretical model using partial least squares (PLS) on survey data...... and a external attitude dimension. The results have important implications for both management control research and for the management control systems design for the way accountants consider the element of risk in their different tasks, both operational and strategic. Specifically, it seems that different risk...

We have grown single crystals of LaOs{sub 4}As{sub 12} and PrOs{sub 4}As{sub 12}, which crystallize in the LaFe{sub 4}P{sub 12}-type structure (Im3-bar space group) with the lattice parameters of 8.542(1) A and 8.520(1) A, respectively. From a narrow {sup 139}La NMR line, we estimated an appreciable Knight shift ({sup 139}K) and a relatively long spin-lattice-relaxation time in the non-4f electron system LaOs{sub 4}As{sub 12}. Surprisingly, while {sup 139}K vary non-monotonically with temperature, the magnetic susceptibility increases upon cooling over the whole temperature range. Interestingly, the high-temperature dependence of the thermoelectric power of LaOs{sub 4}As{sub 12} is remarkably similar to that one of PrOs{sub 4}As{sub 12}.

ABSTRACT: The paper attempts to examine the recent events surrounding the Sovereign Military Order of Malta and their consequences. On one hand it gives an account of the institutional crisis unfolded since December 2016, which started with the suspension of the Grand Chancellor decreed by the Grand Master. However, following a direct intervention on the matter from the Holy See, the Grand Master resigned from his office and a new Lieutenant was elected in his place. On the other hand it points out the most predictable outcomes of the constitutional reform process launched after the resolution of this crisis, with a particular consideration for the role of the professed Knights in the government of the Order - an aspect which is strictly linked to the relation with the Holy See - and for the balance of powers between the Grand Magistry and the other executive bodies, especially the Sovereign Council.

Ruxwana, Nkqubela L; Herselman, Marlien E; Conradie, D Pieter

Information and Communication Technology (ICT) solutions (e.g. e-health, telemedicine, e-education) are often viewed as vehicles to bridge the digital divide between rural and urban healthcare centres and to resolve shortcomings in the rural health sector. This study focused on factors perceived to influence the uptake and use of ICTs as e-health solutions in selected rural Eastern Cape healthcare centres, and on structural variables relating to these facilities and processes. Attention was also given to two psychological variables that may underlie an individual&s acceptance and use of ICTs: usefulness and ease of use. Recommendations are made with regard to how ICTs can be used more effectively to improve health systems at fi ve rural healthcare centres where questionnaire and interview data were collected: St. Lucy&s Hospital, Nessie Knight Hospital, the Tsilitwa Clinic, the Madzikane Ka-Zulu Memorial Hospital and the Nelson Mandela General Hospital.

It is our intention to show that the problems...... these two groups of firms face during the early stages of their existence are to a large extent identical and could, from a theoretical point of view, be analyzed in a unified way. Integrating the two research perspectives above gives rise to a number of interesting research questions that could...... be summarized as follows: a) How do new technology start-ups narrow down the scope of their business activities by effectuating the global dimensions of their businesses? What are the reasons for such firms to look for global resources, partnerships or markets right from inception? b) What makes it possible...

The Impact of Organizational Stress and Burnout on Client Engagement

Landrum, Brittany; Knight, Danica K.; Flynn, Patrick M.

2011-01-01

This paper explores the impact of organizational attributes on client engagement within substance abuse treatment. Previous research has identified organizational features, including small size, accreditation, and workplace practices that impact client engagement (Broome, Flynn, Knight, & Simpson, 2007). The current study sought to explore how aspects of the work environment impact client engagement. The sample included 89 programs located in 9 states across the U.S. Work environment measures included counselor perceptions of stress, burnout, and work satisfaction at each program, while engagement measures included client ratings of participation, counseling rapport, and treatment satisfaction. Using multiple regression, tests of moderation and mediation revealed that staff stress negatively predicted client participation in treatment. Burnout was related to stress, but was not related to participation. Two additional organizational measures – workload and influence – moderated the positive relationship between staff stress and burnout. Implications for drug treatment programs are discussed.

This report documents the ASC/ATDM Kokkos deliverable "Production Portable Dy- namic Task DAG Capability." This capability enables applications to create and execute a dynamic task DAG ; a collection of heterogeneous computational tasks with a directed acyclic graph (DAG) of "execute after" dependencies where tasks and their dependencies are dynamically created and destroyed as tasks execute. The Kokkos task scheduler executes the dynamic task DAG on the target execution resource; e.g. a multicore CPU, a manycore CPU such as Intel's Knights Landing (KNL), or an NVIDIA GPU. Several major technical challenges had to be addressed during development of Kokkos' Task DAG capability: (1) portability to a GPU with it's simplified hardware and micro- runtime, (2) thread-scalable memory allocation and deallocation from a bounded pool of memory, (3) thread-scalable scheduler for dynamic task DAG, (4) usability by applications.

Commercially produced maturity group (MG) IV soybeans, Glycine max L., were sampled during bloom for tarnished plant bugs, Lygus lineolaris (Palisot de Beauvois), during May and June 1999 (3 fields) and 2001 (18 fields). The adults and nymphs were found primarily in single population peaks in both years, indicating a single new generation was produced during each year. The peak mean numbers of nymphs were 0.61 and 0.84 per drop cloth sample in 1999 and 2001, respectively. Adults peaked at 3.96 (1999) and 3.76 (2001) per sweep net sample (25 sweeps). Tests using laboratory-reared and field-collected tarnished plant bugs resulted in very poor survival of nymphs on 16 different soybean varieties (MG III, one; IV, four; V, nine; VI, two). A large cage (0.06 ha) field test found that the number of nymphs produced on eight soybean varieties after mated adults were released into the cages was lower than could be expected on a suitable host. These results indicated that soybean was a marginal host for tarnished plant bugs. However, the numbers of adults and nymphs found in the commercially produced fields sampled in the study may have been high enough to cause feeding damage to the flowering soybeans. The nature of the damage and its possible economic importance were not determined. Reproduction of tarnished plant bugs in the commercially produced early soybean fields showed that the early soybeans provided tarnished plant bugs with a very abundant host at a time when only wild hosts were previously available.

The zygomatic arch is structurally protruded and is easily fractured. The classic management of zygomatic arch fracture has been mentioned the Keen, Lothrop, Dingman and Alling and threaded K-wire. All of the above methods have advantages and disadvantages. To minimize the disadvantages, we performed threaded K-wire for the first time using C-arm image intensifier. The subjects were 16 patients with Knight North group II (Zygomatic arch fracture). Among them the C-arm was used in 12 patients and the operator used sensitivity general method in 4 patients and confirmed the operation by mobile X-ray equipment. In conclusion, both groups were satisfied surgically and cosmetically. Using the C-arm, actual image at the time operation was clear and satisfied, the surrounding tissue damage was minimized and at was more accurately completed. The operation time was shortened by 30 to 60 minutes proving it to be an efficient method. We suggest though that further studies be needed to evaluate the radiation effect on these patients

Social dominance and forceful submission fantasies: feminine pathology or power?

Science.gov (United States)

Hawley, Patricia H; Hensley, William A

2009-01-01

This study addresses forceful submission fantasies in men and women. Although many approaches implicitly or explicitly cast women's force fantasies in a pathological light, this study seeks to explore the associations of such fantasy to female power. By adopting an evolutionary meta-theoretical perspective (and a resource control theory perspective), it was hypothesized that highly agentic, dominant women prefer forceful submission fantasies (more than subordinate women) as a means to connect them to agentic, dominant men. In addition, it is suggested that dominant women would ascribe a meaning to the object of the fantasy different from that assigned by subordinate women (i.e., "warrior lover" vs. "white knight"). Two studies were conducted with nearly 900 college students (men and women) from a large Midwestern university. Hypotheses were largely supported. Analysis of meaning supports theoretical perspectives proposing that forceful submission reflects desires for sexual power on behalf of the fantasist. Implications for evolutionary approaches to human mate preferences are discussed.

This Teaching Resource provides and describes a two-part classroom exercise to help students understand control of the cell cycle, with a focus on the transcription factor p53, the E3 ubiquitin ligase Mdm2, the Mdm2 inhibitor ARF, the kinases ATM and ATR, the kinase Chk2, and the cell cycle inhibitor p21(Cip1). Students use characters and scenes from the movie The Dark Knight to represent elements of the cell cycle control machinery, then they apply these characters and scenes to translate a primary research article on p53 function into a new movie scene in the "Batman universe." This exercise is appropriate for college-level courses in cell biology and cancer biology and requires students to have a background in introductory cell biology. Explicit learning outcomes and associated assessment methods are provided, as well as slides, student assignments, the primary research article, and an instructor's guide for the exercise.

The recently synthesized ThFeAsN iron pnictide superconductor exhibits a Tc of 30 K, the highest of the 1111-type series in the absence of chemical doping. To understand how pressure affects its electronic properties, we carried out microscopic investigations up to 3 GPa via magnetization, nuclear magnetic resonance, and muon-spin rotation experiments. The temperature dependence of the 75As Knight shift, the spin-lattice relaxation rates, and the magnetic penetration depth suggest a multiband s±-wave gap symmetry in the dirty limit, whereas the gap-to-Tc ratio Δ /kBTc hints at a strong-coupling scenario. Pressure modulates the geometrical parameters, thus reducing Tc as well as Tm, the temperature where magnetic-relaxation rates are maximized, both at the same rate of approximately -1.1 K /GPa . This decrease in Tc with pressure is consistent with band-structure calculations, which relate it to the deformation of the Fe 3 dz2 orbitals.
