description: We use a large increase in Federal crop insurance subsidies as a natural experiment to identify the impact of risk on acreage and diversification decisions. Subsidy increases induced greater crop insurance coverage, which reduced farmers' financial risks. Did this change in the risk environment alter production decisions? We merged crop insurance participation data with farm-level Agricultural Census data from 1992 and 1997 to examine how harvested acreage and diversification changed in response to the policy-induced change in insurance coverage. The difference in differences empirical approach controls for unobservable heterogeneity and our results are robust across multiple definitions of our key variables and various fixed effects. We find that changes in the risk environment caused larger farms to expand while smaller farms shrank. Regardless of size, producers showed some evidence of using diversification as a method to mitigate risk. However, risk does not seem to have large overall effects.

description: We present evidence that the outflowing UV absorbers in Seyfert 1 galaxies arise primarily in their inner narrow (emission) line regions (NLRs), based on similarities in their locations, kinematics, and physical conditions. 1) Hubble Space Telescope observations show that nearly all Seyfert galaxies have bright, central knots of [O III] emission in their NLRs with radii of tens of parsecs. These sizes are consistent with most previous estimates of the distances of UV (and X-ray) absorbers from their central continuum sources, and a recently obtained reliable distance of ~25 pc for a UV absorber in the Seyfert 1 galaxy NGC 3783. 2) The nuclear emission-line knots in a sample of 10 Seyfert galaxies have velocity widths of 300 - 1100 km/s (half-width at zero intensity), similar to the radial velocities of most UV absorbers. The highest radial velocity for a Seyfert UV absorber to date is only -2100 km/s, which is much lower than typical broad-line region (BLR) velocities. There is also mounting evidence that the NLR clouds are outflowing from the nucleus, like the UV absorbers. 3) If our hypothesis is correct, then the NLR must have a component with a high global covering factor (Cg) of the continuum source and BLR, to match that found from previous surveys of UV absorbers (Cg = 0.5 - 1.0). Using STIS spectra of NGC 4151, obtained when the continuum and BLR fluxes were low, we find evidence for optically thin gas in its nuclear emission-line knot. We are able to match the line ratios from this gas with photoionization models that include a component with Cg ~ 1 and an ionization parameter and hydrogen column density that are typical of UV absorbers.

description: The gravitational dipole theory of Hadjukovic (2010) is based on the hypothesis that antimatter has a negative gravitational mass and thus falls upwards on Earth. Astrophysically, the model is similar to but more fundamental than Modified Newtonian Dynamics (MOND), with the Newtonian gravity $g_{_N}$ towards an isolated point mass boosted by the factor $ν= 1 + \left( α/x \right) \tanh \left( \sqrt{x}/α\right)$, where $x \equiv g_{_N}/a_{_0}$ and $a_{_0} = 1.2 \times 10^{-10}$ m/s$^2$ is the MOND acceleration constant. We show that $α$ must lie in the range ${0.4-1}$ to acceptably fit galaxy rotation curves. In the Solar System, this interpolating function implies an extra Sunwards acceleration of ${αa_{_0}}$. This would cause Saturn to deviate from Newtonian expectations by ${7000 \left( α/0.4 \right)}$ km over 15 years, starting from known initial position and velocity on a near-circular orbit. We demonstrate that this prediction should not be significantly altered by the postulated dipole haloes of other planets due to the rather small region in which each planet's gravity dominates over that of the Sun. The orbit of Saturn should similarly be little affected by a possible ninth planet in the outer Solar System and by the Galactic gravity causing a non-spherical distribution of gravitational dipoles several kAU from the Sun. Radio tracking of the Cassini spacecraft orbiting Saturn yields a ${5σ}$ upper limit of 160 metres on deviations from its conventionally calculated trajectory. These measurements imply a much more stringent upper limit on $α$ than the minimum required for consistency with rotation curve data. Therefore, no value of $α$ can simultaneously match all available constraints, falsifying the gravitational dipole theory in its current form at extremely high significance.

description: A method for the general analysis of the sensitivities of neutron beta-decay experiments to manifestations of possible deviations from the Standard model is proposed. In a consistent fashion, we take into account all known (radiative and recoil) corrections which are incorporated within the Standard Model to provide a description of angular correlations in neutron decay in the first order of approximation, or down to the level of $\sim 10^{-5}$. The contributions from models beyond the Standard model are, for low energy neutron decay, parameterized in terms of vector, axial-vector, scalar and tensor coupling constants and in terms of parameters related to specific models. For the present analysis we derive the exact expressions for the neutron beta decay probability which includes all possible manifestations models beyond the Standard Model down to level of $\sim 10^{-5}$ without time-reversal violation. Based on the general expressions for manifestation of the deviations from the standard model, we present analysis of the sensitivities for selected neutron decay experiments.

description: We study hysteretic magnetoresistance in InSb nanowires due to stray magnetic fields from CoFe micromagnets. Devices without any ferromagnetic components show that the magnetoresistance of InSb nanowires commonly exhibits either a local maximum or local minimum at zero magnetic field. Switching of microstrip magnetizations then results in positive or negative hysteretic dependence as conductance maxima or minima shift with respect to the global external field. Stray fields are found to be in the range of tens of millitesla, comparable to the scale over which the nanowire magnetoresistance develops. We observe that the stray field signal is similar to that obtained in devices with ferromagnetic contacts (spin valves). We perform micromagnetic simulations which are in reasonable agreement with the experiment. The use of locally varying magnetic fields may bring new ideas for Majorana circuits in which nanowire networks require control over field orientation at the nanoscale.

description: We present a study of the dijet invariant mass distribution for the reaction $\pbp \to 2 $jets$+γ+X$, at a center of mass energy of 1.8 TeV, using data collected by the CDF experiment. We compare the data to predictions for the production of a photon with two jets, together with the resonant processes $\pbp \to W/Z+γ+X$, in which the $W$ and $Z$ bosons decay hadronically. A fit is made to the dijet invariant mass distribution combining the non-resonant background and resonant processes. We use the result to establish a limit for the inclusive production cross section of $W/Z+γ$ with hadronic decay of the $W$ and $Z$ bosons.

description: This paper derives a simulation model that examines the food security of the grain producing households in China in an open border model regime. We define a food inadequacy index (F.I.) to measure the change of the food security status under alternative scenarios of border liberalization for the households. We conclude that if opening the border of grain market is followed by a more variable grain price distribution, the food security status will deteriorate for the low-income households on average. However, if border liberalization is followed by a decrease in mean of the price distribution, even with a more variable distribution, the food security status improves.

description: This postcard is from my grandfather Charles Hindley to his parents and the insert with the card is dated 1914/15. The postcard is made by a company in Paris. He has written on the back "1/7 west Riding Regiment , 49 Div and BEF." The story I was told was that at some point he was "mustard gassed" and woke up in a church which was being used as a mortuary, surrounded by dead colleagues. When he went to the door to leave the sentries ran off!Researching the regiment's movements it would appear the div was mobilised in August 1914. In April 15 they were in France as part of the BEF on the western front. It was redesignated The 49th (West Riding) Div in May 1915. The Div was a target for the first German Phosgene attack against British troops in December 1915 at Wieltje in N.E. Ypres in Belgium Flanders which may fit with the family story handed down to us.

description: Quasilocal definitions of stress-energy-momentum---that is, in the form of boundary densities (in lieu of local volume densities)---have proven generally very useful in formulating and applying conservation laws in general relativity. In this essay, we take a first basic look into applying these to cosmology, specifically using the Brown-York quasilocal stress-energy-momentum tensor for matter and gravity combined. We compute this tensor and present some simple results for a flat FLRW spacetime with a perfect fluid matter source.

description: The costs of corn- and soybean-based feeds compose a substantial proportion of the variable costs faced by both mainstream and emergent confined livestock producers. This research develops a method to provide a joint distribution of prices of corn and soybean meal at a future time. Black's 1976 option model and stochastic volatility jump diffusion (SVJD) model are compared in volatility forecasting performance. In general, SVJD is superior to Black's model, though their performance is both commodity-specific and forecasting horizon specific. The price forecast can assist livestock producers to assess different feed procurement strategies in terms of the distribution of costs projected for each strategy.
Competitive Accretion and the IMF

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Competitive accretion occurs when stars in a cluster accrete from a shared reservoir of gas. The competition arises due to the relative attraction of stars as a function of their mass and location in the cluster. The low relative motions of the stars and gas in young, gas dominated clusters results in a tidal limit to the accretion whereas in the stellar dominated cluster cores, the high relative velocities results in Bondi-Hoyle accretion. The combination of these two accretion processes produces a two power-law IMF with $γ\approx -1.5$, for low-mass stars which accrue their mass in the gas dominated regime, and a steeper, $γ\approx -2.5$, IMF for higher-mass stars that form in the core of a cluster. Simulations of the fragmentation and formation of a stellar cluster show that the final stellar masses, and IMF, are due to competitive accretion. Competitive accretion also naturally results in a mass segregated cluster and in a direct correlation between the richness of a cluster and the mass of the most massive star therein. The {\sl knee} where the IMF slope changes occurs near the Jeans mass of the system.

description: We design and implement a quantum laboratory to experimentally observe and study dynamical processes of quantum field theories. Our approach encodes the field theory as an Ising model, which is then solved by a quantum annealer. As a proof-of-concept, we encode a scalar field theory and measure the probability for it to tunnel from the false to the true vacuum for various tunnelling times, vacuum displacements and potential profiles. The results are in accord with those predicted theoretically, showing that a quantum annealer is a genuine quantum system that can be used as a quantum laboratory. This is the first time it has been possible to experimentally measure instanton processes in a freely chosen quantum field theory. This novel and flexible method to study the dynamics of quantum systems can be applied to any field theory of interest. Experimental measurements of the dynamical behaviour of field theories are independent of theoretical calculations and can be used to infer their properties without being limited by the availability of suitable perturbative or nonperturbative computational methods. In the near future, measurements in such a quantum laboratory could therefore be used to improve theoretical and computational methods conceptually and may enable the measurement and detailed study of previously unobserved quantum phenomena.

description: This work presents a novel realization approach to Quantum Boltzmann Machines (QBMs). The preparation of the required Gibbs states, as well as the evaluation of the loss function's analytic gradient is based on Variational Quantum Imaginary Time Evolution, a technique that is typically used for ground state computation. In contrast to existing methods, this implementation facilitates near-term compatible QBM training with gradients of the actual loss function for arbitrary parameterized Hamiltonians which do not necessarily have to be fully-visible but may also include hidden units. The variational Gibbs state approximation is demonstrated with numerical simulations and experiments run on real quantum hardware provided by IBM Quantum. Furthermore, we illustrate the application of this variational QBM approach to generative and discriminative learning tasks using numerical simulation.
Autonomy, technology and Spanish as a Second Language

description: Literature on self-directed language learning has only begun to explore the potential of the Internet for language acquisition. This diary case study involved the researcher-as-participant in self-directed learning of Spanish as a Second Language, over a period of 3.5 months. Only freely available Internet-based resources and communication tools were used to acquire Spanish language skills. Multiple pretest and posttest scores were recorded for all of the language skills, as well as observations of language learning strategies, motivation, and the use of multimedia in this language learning context. The results indicate that motivation was positively affected by the degree to which the learner had access to authentic language communities, through the use of authentic materials and communication tools. It was also found that self-directed learning in this environment required a high degree of metacognitive strategies, which at times had a negative effect on the learning process. Qualitative and quantitative measurements indicated that there was a significant increase in listening comprehension ability, as a result of reliable and consistent access to authentic online radio and television. The researcher suggests that Internet-based learning might be appropriate to autonomous learners who require access to authentic communities and materials in order to learn effectively.

description: James Robert Seddon enlisted in the Loyal North Lancashire Regiment on the 11th November 1914 when he was 20 years old; he had worked down the mines as a collier from the age of 13 and thought that signing up to do his bit would be a great change and an opportunity not to be missed.

He fought – and was wounded three times – at Ypres and the Somme. He was discharged at the end of the war but due to his injuries he was not able to go down the mines again and worked as a general labourer and later a postman. By the autumn of 1930 his health had started to deteriorate both physically and mentally and he spent an increasing amount of time out of work and in convalescence homes recovering from neurasthenia – or shell shock.

Finally in October 1930 he asked if he could have a War Pension – this was refused and on the back of the envelope which held the letter refusing his pension he drafted this letter ....

"15th November 1916 Mailly-Maillet in the fight for Beaumont Hamel I was sent to General Hospital at Le Havre and from there I was sent to Isigny Hospital in Le Havre where I was x rayed and a piece of shrapnel was taken from over left eye. I stayed in hospital in Le Havre about a month and then I was sent to Royal Infirmary Edinburgh then on to convalescence at Clifton Park House B/pool (Blackpool).

Rejoining Reg(iment) May 1917

As I was able to follow my employment I never xxx but I have always suffered from pain ....."

And there the draft letter ends but we know that he was again refused a War Pension. His local Labour MP - Alexander Haycock - heard of his story and intervened and one month later he got a letter awarding him his pension of 12 shillings (about 60 pence) per week.

It is a structural and counting based topological index that has received more and more attention in recent years. In this paper we first obtain exact formulas for the expected values of subtree number index of random polyphenylene and spiro chains, which are molecular graphs of a class of unbranched multispiro molecules and polycyclic aromatic hydrocarbons. Moreover, we establish a relation between the expected values of the subtree number indices of a random polyphenylene and its corresponding hexagonal squeeze. We also present the average values for subtree number indices with respect to the set of all polyphenylene and spiro chains with $n$ hexagons.

description: A typical private good is defined by its excludability and rivalry characteristics. Information might not generate rivalry among its users. By contrast, excludability is certainly a characteristic of information and its delivery can generate incentives for private participation. This study examines farmers' preferences for seed of new rice varieties and their willingness to pay for related information in villages of Nigeria and Benin. Conjoint analysis is used to estimate the structure of farmers' preferences for rice seed given a set of alternatives. Farmers are considered to be maximizers of utility rather than profit, preferring one variety over another based on the utility they obtain from its attributes, which depends on their own social and economic characteristics. Contingent methods are used to elicit preferences and willingness to pay (WTP) for rice seed. The marginal values of attributes, with and without information about the seed, are estimated with an ordered probit regression. WTP for information is derived from the analysis of WTP for rice seed. The results have implications for the best way to finance research and extension services in the areas of intervention, particularly for new rice varieties.

description: As an independent check on previous measurements of the isotopic abundance of oxygen through the Galaxy, we present a detailed analysis of the ground state rotational lines of 16OH and 18OH in absorption towards the giant molecular cloud complex, Sagittarius B2. We have modelled the line shapes to separate the contribution of several galactic clouds along the line of sight and calculate 16OH/18OH ratios for each of these features. The best fitting values are in the range 320-540, consistent with the previous measurements in the Galactic Disk but slightly higher than the standard ratio in the Galactic Centre. They do not show clear evidence for a gradient in the isotopic ratio with galactocentric distance. The individual 16OH column densities relative to water give ratios of [H2O/OH]=0.6-1.2, similar in magnitude to galactic clouds in the sight lines towards W51 and W49. A comparison with CH indicates [OH/CH] ratios higher than has been previously observed in diffuse clouds. We estimate OH abundances of 10^-7 - 10^-6 in the line of sight features.

In previous works we showed that a set of nodeless solutions of the fundamental branch of the model studied in [1] are stable under both radial [2] and axial perturbations [3]. Here we calculate the polar quasinormal modes and show that this set of solutions is stable against the polar perturbations as well. Thus for a certain region of the parameter space the scalarized black holes are potentially stable physically interesting objects. The spectrum of the polar quasinormal modes differs both quantitatively and qualitatively from the Schwarzschild one which offers the possibility to test the Gauss-Bonnet theory via the future gravitational wave observations.

Investigating the picture book preferences of grade four Aboriginal students
Creators: name: Boyle, Erin Elizabeth O'Byrne
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of the study is to investigate the picture book preferences of grade four Aboriginal students, to discover what books have the greatest appeal and to determine which specific factors influence their choices. The study took place at an inner city elementary school with a high population of Aboriginal students located in the heart of the Canadian prairies. Experienced educators know that the majority of Aboriginal chidlren come to school with little or no exposure to books. Studies have shown that the ability or lack of ability to read at grade level is a strong indicator of future academic success. Teachers and librarians have little information available to assist them in choosing literature that will be of interest to Aboriginal students and motivate them to read and through practice improve their reading skills. Provincial governments are looking for research that addresses the needs of this growing population. Twelve grade four Aboriginal students participated in the study, seven boys and five girls. The students viewed forty-five books that were divided into three sets of fifteen and chose one book from each set to read and respond to through writing and/or drawing. After the book selection and response sessions were complete, the researcher interviewed each child to determine the one book they would most want to take home. The study concludes that: 1) Students preferred to read picture books portraying Aboriginal characters that reflected their own image; 2) Students transposed the urban and rural settings in the Aboriginal books to make relevant connections with their lives; 3) Aboriginal books portraying Aboriginal characters was the genre with the greatest appeal; 4) Students preferred vivid realistic illustrations; 5) Students background experience frequently determined their preferences in books and also increased their motivation to read; 5) Realistic pictures with minimal amounts of text held great appeal for boys selecting information books. It is hoped that the study will assist teachers and librarians in selecting literature that will be of interest to Aboriginal students encouraging them to read more and by improving their reading skills raise the level of their general academic achievement.

description: Andrew Osmond (1891-1966) served in World War One. From his number (1806) I learned from the very knowledgeable Andrew French that he joined the Berkshire Yeomanry in the spring of 1913 when he was 21. The Hungerford Troop was merged with the Reading Squadron of the Berkshire Yeomanry and the men in Troop B spent the autumn of 1914 exercising on the Downs above Blewbury on Churn land. They were frustrated not to have been sent overseas, because everyone believed the war would be over by Christmas 1914. Finally they went to war in spring 1915. They were sent to Egypt and landed at Alexandria on 21st April 1915. Although they were a mounted troop, the decision was taken that they would fight as infantry and on 14th August 1915 314 men and 9 officers sailed from Alexandria aboard the SS Lake Michigan and landed at Sulva on the Gallipoli peninsula 4 days later. They then fought some of the bloodiest of battles in the Dardanelles. The battle of Hill 70 (known as Scimitar or Burnt Hill) is well documented. Of those who went into action, 4 officers and 150 men returned and there were six men made Prisoners Of War (PoW), Sgt WJ Babister, Tpr A Calder, Tpr P New, Tpr W Collins and Tpr O Walter. Of these Collins died while in captivity. Percy New was also a Hungerford man and had enlisted a few months before Osmond. Babister was awarded the Military Service Medal for his services whilst in captivity. Some experts think that those few taken prisoner were at the very front of the attack and as a PoW, Osmond probably made it past the second Turkish trench line and was one of those who continued the advance over the top of the hill and down the reverse side of the hill to attack the final trenches at the rear of the hill. This battle is most famous for the awarding of the Victoria Cross to Trooper Fred Potts who rescued one of his colleagues Private Arthur Andrews and whose statue was recently unveiled in Forbury Gardens in Reading. Osmond was in the same troop of the Berkshire Yeomanry as Potts as the picture shows. Potts is 4th from the left in the back row and Walter is 2nd from the right in the front row. Osmond was held prisoner in Turkey for the remainder of the war. I have no details of his captivity apart from a newspaper article in April 1918 asking for provisions, which were sent out by the Berkshire yeomanry Comfort's Fund. It is documented that the prisoners were held in people's homes in Turkey and were treated very cruelly, some say as badly as the Japanese prisoners of war in World War Two. Suffice to say that Osmond survived and returned home in 1918.

description: We describe recent developments of the public computer code HiggsBounds. In particular, these include the incorporation of LHC Higgs search results from Run 2 at a center-of-mass energy of 13 TeV, and an updated and extended framework for the theoretical input that accounts for improved Higgs cross section and branching ratio predictions and new search channels. We furthermore discuss an improved method used in HiggsBounds to approximately reconstruct the exclusion likelihood for LHC searches for non-standard Higgs bosons decaying to $ττ$ final states. We describe in detail the new and updated functionalities of the new version HiggsBounds-5.

description: Dualities of M-theory are used to determine the exact dependence on the coupling constant of the D^6R^4 interaction of the IIA and IIB superstring effective action. Upon lifting to eleven dimensions this determines the coefficient of the D^6R^4 interaction in eleven-dimensional M-theory. These results are obtained by considering the four-graviton two-loop scattering amplitude in eleven-dimensional supergravity compactified on a circle and on a two-torus -- extending earlier results concerning lower-derivative interactions. The torus compactification leads to an interesting SL(2,Z)-invariant function of the complex structure of the torus (the IIB string coupling) that satisfies a Laplace equation with a source term on the fundamental domain of moduli space. The structure of this equation is in accord with general supersymmetry considerations and immediately determines tree-level and one-loop contributions to D^6R^4 in perturbative IIB string theory that agree with explicit string calculations, and two-loop and three-loop contributions that have yet to be obtained in string theory. The complete solution of the Laplace equation contains infinite series' of single D-instanton and double D-instanton contributions, in addition to the perturbative terms. General considerations of the higher loop diagrams of eleven-dimensional supergravity suggest extensions of these results to interactions of higher order in the low energy expansion.

description: HARPS spectra with signal-to-noise ratios S/N > 600 at 6000 A were analysed with MARCS model atmospheres to obtain 1D LTE abundances of C, O, Na, Mg, Al, Si, Ca, Ti, Cr, Fe, Ni, Sr, and Y for 72 nearby solar-type stars with metallicities in the range -0.3 < [Fe/H] < +0.3 and ASTEC stellar models were used to determine stellar ages from effective temperatures, luminosities obtained via Gaia DR2 parallaxes, and heavy element abundances. The resulting age-metallicity distribution appears to consist of two distinct populations: a sequence of old stars with a steep rise of [Fe/H] to about +0.3 dex at an age of ~7 Gyr and a younger sequence with [Fe/H] increasing from -0.3 dex to about +0.2 dex over the last six Gyr. Furthermore, the trends of several abundance ratios, [O/Fe], [Na/Fe], [Ca/Fe], and [Ni/Fe], as a function of stellar age split into two corresponding sequences. The [Y/Mg]-age relation, on the other hand, shows no offset between the two age sequences and has no significant dependence on [Fe/H], but the components of a visual binary star, zeta Reticuli, have a large and puzzling deviation. The split of the age-metallicity distribution into two sequences may be interpreted as evidence of two episodes of accretion of gas onto the Galactic disk with a quenching of star formation in between. Some of the [X/Fe]-age relations support this scenario but other relations are not so easy to explain, which calls for a deeper study of systematic errors in the derived abundances as a function of [Fe/H], in particular 3D non-LTE effects.

description: A global economy-wide model (GTAP) is used to go beyond estimating how GM crop variety adoption affects adopting and non-adopting economies, with or without policy responses to this technology, by indicating effects also on real incomes of farmers. The results suggest the EU moratorium on imports of GM food helps EU farmers even though it requires them to forego the productivity boost they could receive from the new biotechnology. An upper-bound estimate of the cost of that EU moratorium to developing countries and the world also is provided.

Hard Superconductivity of a Soft Metal in the Quantum Regime

description: Superconductivity is inevitably suppressed in reduced dimensionality. Questions of how thin superconducting wires or films can be before they lose their superconducting properties have important technological ramifications and go to the heart of understanding coherence and robustness of the superconducting state in quantum-confined geometries. Here, we exploit quantum confinement of itinerant electrons in a soft metal to stabilize superconductors with lateral dimensions of the order of a few millimeters and vertical dimensions of only a few atomic layers. These extremely thin superconductors show no indication of defect- or fluctuation-driven suppression of superconductivity and sustain supercurrents of up to 10% of the depairing current density. The extreme hardness of the critical state is attributed to quantum trapping of vortices. This study paints a conceptually appealing, elegant picture of a model nanoscale superconductor with calculable critical state properties. It indicates the intriguing possibility of exploiting robust superconductivity at the nanoscale.

description: The study of X-point collapse in magnetic reconnection has witnessed extensive research in the context of space and laboratory plasmas. In this paper, a recently derived mathematical formulation of X-point collapse applicable in the regime of extended magnetohydrodynamics (XMHD) is shown to possess a noncanonical Hamiltonian structure composed of five dynamical variables inherited from its parent model. The Hamiltonian and the noncanonical Poisson bracket are both derived, and the latter is shown to obey the requisite properties of antisymmetry and the Jacobi identity (an explicit proof of the latter is provided). In addition, the governing equations for the Casimir invariants are presented, and one such solution is furnished. The above features can be harnessed and expanded in future work, such as developing structure-preserving integrators for this dynamical system.

Does Low Frequency X-ray QPO Behavior in GRS 1915+105 Influence Subsequent X-ray and Infrared Evolution?

description: Using observations with the Rossi X-ray Timing Explorer, we examine the behavior of 2-10 Hz quasi-periodic oscillations (QPOs) during spectrally-hard dips in the x-ray light curve of GRS 1915+105 that are accompanied by infrared flares. Of the twelve light-curves examined, nine are beta-class and three are alpha-class following the scheme of Belloni et al. (2000). In most cases, the QPO frequency is most strongly correlated to the power law flux, which partially contradicts some earlier claims that the strongest correlation is between QPO frequency and blackbody flux. Seven beta-class curves are highly correlated to blackbody features. In several cases, the QPO evolution appears to decouple from the spectral evolution. We find that beta-class light-curves with strong correlations can be distinguished from those without by their ``trigger spike'' morphology. We also show that the origin and strength of the subsequent infrared flare may be causally linked to the variations in QPO frequency evolution and not solely tied to the onset of soft x-ray flaring behavior. We divide the twelve alpha- and beta-class light-curves into three groups based on the evolution of the QPO, the morphology of the trigger spike, and the infrared flare strength. An apparent crossover case leads us to conclude that these groups are not unique modes but represent part of a continuum of accretion behaviors. We believe the QPO behavior at the initiation of the hard dip can ultimately be used to determine the terminating x-ray behavior, and the following infrared flaring behavior.

description: To date, most research in Europe and the United States has focused on eliciting consumer WTP for biotech foods without directly addressing strategies for marketing them. We use means-end theory to link consumers' knowledge about functional attributes, to their knowledge about consequences and core values, in order to gain insights into valued attributes for developing potential marketing strategies.
