description: During the last two years the RealityGrid project has allowed us to be one of the few scientific groups involved in the development of computational grids. Since smoothly working production grids are not yet available, we have been able to substantially influence the direction of software development and grid deployment within the project. In this paper we review our results from large scale three-dimensional lattice Boltzmann simulations performed over the last two years. We describe how the proactive use of computational steering and advanced job migration and visualization techniques enabled us to do our scientific work more efficiently. The projects reported on in this paper are studies of complex fluid flows under shear or in porous media, as well as large-scale parameter searches, and studies of the self-organisation of liquid cubic mesophases.

description: The first FUV (lambda lambda 1350-1750 A) spectral imaging observations of the Eridanus superbubble, obtained with the SPEAR/FIMS mission, have revealed distinct fluorescent emission from molecular hydrogen. In this study, the observed emission features were compared with those from a photo-dissociation region model with assumed illuminating stellar fields. The result showed rather high line ratios of I_{1580}/I_{1610}, which may imply the existence of high-temperature molecular clouds in the region. The H_2 fluorescence intensity showed a proportional correlation with H-alpha emission, indicating that the fluorescence and the recombination emission have similar physical origins.

description: A multinomial logit analysis is employed to analyze consumers' perceptions about purchasing biotech foods and their preferences for mandatory and voluntary labeling. Results showed that consumers who are sensitive to the possible side effects of biotech crops on wildlife and the environment are more likely to support a mandatory labeling policy. Results also indicated that respondents who believe biotech foods may have unforeseen health risks are more likely to favor mandatory labeling. Furthermore, the study found that respondents who are willing to buy a meat product produced using biotechnology are more likely to favor a voluntary labeling policy.

description: By Faraday-rotation fluctuation spectroscopy one measures the spin noise via Faraday-induced fluctuations of the polarization plane of a laser transmitting the sample. In the fist part of this paper, we present a theoretical model of recent experiments on alkali gas vapors and semiconductors, done in the presence of a {\em static} magnetic field. In a static field, the spin noise shows a resonance line, revealing the Larmor frequency and the spin coherence time $T_2$ of the electrons. Second, we discuss the possibility to use an {\em oscillating} magnetic field in the Faraday setup. With an oscillating field applied, one can observe multi-photon absorption processes in the spin noise. Furthermore an oscillating field could also help to avoid line broadening due to structural or chemical inhomogeneities in the sample, and thereby increase the precision of the spin-coherence time measurement.

description: One of the key factors affecting the crop output is the rainfall volume. For this reason, insurance plans based on the rainfall deviation of the mean have been advanced. This paper provides prospects of rainfall-indexed insurance in Romania considering the tradeoff between moral hazard and basis risks. The reasonability of rainfall-indexed insurance will be judged first. The basic parameters will then be determined and the effectiveness will be measured. Finally, microfinance programs combined with indexed insurance will be advanced to deal with the basis risk problems, which also are the goals for further study
Structure and stellar content analysis of the open cluster M11 with 2MASS photometry

description: An overall analysis of the structure and stellar content of M11 is presented, thanks to the wide-angle 2MASS spatial coverage. We derive photometric and structural parameters and discuss the spatial dependance of the luminosity and mass functions. Photometric parameters basically agree with previous ones mostly based on the optical. We obtained a core radius of 1.23pc and a tidal radius of 29pc. In particular, the cluster is populous enough so that the tidal radius could be obtained by fitting the three-parameter King profile to the radial distribution of stars. We analyzed the spatial distribution of mass functions, finding that the the slope changes from -0.73 in the core to +2.88 in the outer halo. The spatial distribution of mass function slopes derived from 2MASS agrees with that derived from optical CCD data, which further confirms the reliability of 2MASS data for future analyses of this kind at comparable observational limits. We detect mass segregation up to distances from the center of ~20arcmin. We emphasize that the mass function slope in the core is flatter than anywhere else as a consequence of mass segregation. The derived total cluster mass is ~11000 solar masses.

CROP INSURANCE, GOVERNMENT AGRICULTURAL POLICIES, AND SOIL EROSION

Subjects: Environmental Economics and Policy

description: This paper investigates the relationship between government agricultural programs and soil erosion. Using county-level data from the years 1992 and 1997, we estimate a model of water-induced (i.e., sheet and rill) soil erosion and crop insurance participation for counties where corn, soybean, and winter wheat account for at least 90% of total planted acreage. This includes most of the areas that have exhibited the highest historical levels of sheet and rill erosion. We find that crop insurance participation and conservation payments are significantly associated with county average soil erosion levels. In particular, corn insurance participation exhibits a positive impact on soil erosion, while wheat insurance participation exhibits a negative impact. After controlling for differences in soil erodibility, counties that receive higher conservation payments exhibit lower levels of soil erosion. We also find that government price and income support program payments (e.g., target price-based/loan deficiency payments and AMTA payments) exhibit no statistically significant association with our soil erosion measure.
Stationary state volume fluctuations in a granular medium

description: A statistical description of static granular material requires ergodic sampling of the phase space spanned by the different configurations of the particles. We periodically fluidize a column of glass beads and find that the sequence of volume fractions phi of post-fluidized states is history independent and Gaussian distributed about a stationary state. The standard deviation of phi exhibits, as a function of phi, a minimum corresponding to a maximum in the number of statistically independent regions. Measurements of the fluctuations enable us to determine the compactivity X, a temperature-like state variable introduced in the statistical theory of Edwards and Oakeshott [Physica A {\bf 157}, 1080 (1989)].

description: A finite-size scaling approach based on the transfer matrix method is developed to calculate the critical temperature and critical exponent of the symmetric and the asymmetric two-layer three-state Potts Models. For similar intralayer interactions our calculation of the shift exponent $ϕ$ confirm some scaling arguments which predict $ϕ= γ$, where $γ$ is the susceptibility exponent. For unequal intralayer interactions we have obtained $ϕ= 0.5 $ which differs from the prediction $ϕ= {γ/ 2} $ of a generalized mean-field theory.

description: Diese Arbeit bietet einen Beitrag zur Weiterentwicklung von Regelungs- und Vorsteuerungsstrategien von Windenergieanlagen mit Einzelblattverstellung. Der Fokus liegt auf dem Entwurf einer LiDAR-basierten Einzelblattvorsteuerung und einer transparenten, belastbaren Abschätzung des Potenzials als Alternative zur Einzelblattregelung auf Basis gemessener Blattwurzelbiegemomente. Die Vorsteuerung wird als Störgrößenkompensation zur Kompensation rotoreffektiver Windfeldvariablen inklusive der horizontalen und vertikalen Schräganströmung aufgebaut. Zur Untersuchung des Verhaltens bei Schräganströmung wird der skewed wake effect modelliert und anhand von Vermessungsdaten einer Windenergieanlage im Feld parametriert. Neben der Entwicklung eines geeigneten Entwurfsmodells auf Basis der BEM-Theorie und einer linearen Vorsteuerung liegen die Schwerpunkte der Arbeit im Aufbau einer adäquaten Simulationsumgebung mit realitätsnaher LiDAR-Messkette und der Entwicklung einer praxistauglichen Einzelblattregelung, die sowohl simulativ als auch im Feld validiert wird.

description: We theoretically study the quench dynamics of induced anisotropy of a large-spin magnetic molecule coupled to spin-polarized ferromagnetic leads. The real-time evolution is calculated by means of the time-dependent density-matrix numerical renormalization group method implemented within the matrix product states framework, which takes into account all correlations in very accurate manner. We determine the system's response to a quench in the spin-dependent coupling to ferromagnetic leads. In particular, we focus on the transient dynamics associated with crossing from the weak to the strong coupling regime, where the Kondo correlations become important. The dynamics is examined by calculating the time-dependent expectation values of the spin-quadrupole moment and the associated spin operators. We identify the relevant time scales describing the quench dynamics and determine the influence of the molecule's effective exchange coupling and leads spin-polarization on the dynamical behavior of the system. Furthermore, the generalization of our predictions for large values of molecule's spin is considered. Finally, we analyze the effect of finite temperature and show that it gives rise to a reduction of magnetic anisotropy by strong suppression of the time-dependent spin-quadrupole moment due to thermal fluctuations.

description: We analyze the effects of crop insurance and the Marketing Loan Program on optimal nitrogen use and acreage allocation for a case cotton-sorghum farm in Texas. A mathematical programming model is used to simulate the optimal nitrogen fertilizer rate, crop acreage allocation, coverage level, and price election factor, along with participation in the crop insurance (APH and CRC) and the Marketing Loan Program for both crops. Results show that current insurance programs increase the optimal fertilizer rate 1-3% and increase the optimal cotton acreage 16-129%. The Marketing Loan Program slightly changes optimal fertilizer rates and increases optimal cotton acreage an additional 1-9%.

description: Recent breakthroughs in Deep Neural Networks (DNNs) have fueled a tremendously growing demand for bringing DNN-powered intelligence into mobile platforms. While the potential of deploying DNNs on resource-constrained platforms has been demonstrated by DNN compression techniques, the current practice suffers from two limitations: 1) merely stand-alone compression schemes are investigated even though each compression technique only suit for certain types of DNN layers; and 2) mostly compression techniques are optimized for DNNs' inference accuracy, without explicitly considering other application-driven system performance (e.g., latency and energy cost) and the varying resource availability across platforms (e.g., storage and processing capability). To this end, we propose AdaDeep, a usage-driven, automated DNN compression framework for systematically exploring the desired trade-off between performance and resource constraints, from a holistic system level. Specifically, in a layer-wise manner, AdaDeep automatically selects the most suitable combination of compression techniques and the corresponding compression hyperparameters for a given DNN. Thorough evaluations on six datasets and across twelve devices demonstrate that AdaDeep can achieve up to $18.6\times$ latency reduction, $9.8\times$ energy-efficiency improvement, and $37.3\times$ storage reduction in DNNs while incurring negligible accuracy loss. Furthermore, AdaDeep also uncovers multiple novel combinations of compression techniques.

title: Collective Effects in the Hadron Future Circular Collider
Creators: name: Astapovych, Daria
Publisher: name: UNSPECIFIED
Year: 2020

description: The instability of a beam in hadron circular accelerators due to the beam coupling impedance and electron clouds is investigated. The Future hadron-hadron Circular Collider (FCC-hh) is a potential successor of the Large Hadron Collider (LHC). FCC-hh will operate at 100 TeV collision energy in a tunnel with a circumference of 100 km, in comparison to 14 TeV collision energy and 27 km circumference in the LHC. Similarly to the LHC, in the FCC-hh the beam screen can be a limiting factor for beam stability. The electromagnetic interaction of the beam and beam screen is described by a beam coupling impedance, whereas the interaction between the beam and free electrons in the beam pipe leads to the formation of the electron cloud. As a result, machine performance can be affected by beam instabilities, beam losses, heat load, and vacuum degradation. Absolute predictions of collective effects require the most realistic impedance database. Because of uncertainties in the electromagnetic material properties and missing component details at the present design stage of the beam screen, the absolute estimations would carry large error bars. Instead, this thesis focuses on the scaling of collective effects with beam energy and beam screen geometry from LHC to FCC-hh, as this can relate actual observations from an existing collider to a new one, with many similarities. The impedances are computed for the detailed transverse cross-section for the FCC-hh and the LHC beam screens. The current design of the FCC-hh beam screen is found to make a significant contribution to impedance. Based on an analysis of impedance-induced effects, this thesis work proposes modifications in the beam screen design to mitigate its impedance contribution. An electron cloud buildup study is also performed for the detailed transverse cross-section for the FCC-hh and the LHC beam screens. As a result of these computations, one can conclude that an additional coating on the FCC-hh beam screen is required to mitigate the effects driven by the electron cloud. Further, to investigate the impact on the effects induced by electron clouds due to the higher beam energy and smaller aperture of FCC-hh beam screen in comparison to LHC, a study of the heat load with beam energy and pipe radius is performed.

description: We present an alternative derivation of upper-bounds for the bulk modulus of both two-dimensional and three-dimensional cellular materials. For two-dimensional materials, we recover exactly the expression of the Hashin-Shtrikman (HS) upper-bound in the low-density limit, while for three-dimensional materials we even improve the HS bound. Furthermore, we establish necessary and sufficient conditions on the cellular structure for maximizing the bulk modulus, for a given solid volume fraction. These conditions are found to be exactly those under which the electrical (or thermal) conductivity of the material reaches its maximal value as well. These results provide a set of straightforward criteria allowing to address the design of optimized cellular materials, and shed light on recent studies of structures with both maximal bulk modulus and maximal conductivity. Finally, we discuss the compatibility of the criteria presented here with the geometrical constraints caused by minimization of surface energy in a real foam.

Self-selection for pork differs from broiler production resulting in a predictably different political response by incumbent producers to contract innovation. The higher capital and status of incumbent pork producers than poultry producers account for much of the difference.

description: FM (Frequency modulation) halftoning (aperiodic, dispersed-dot) is widely used with inkjet printers in both low-end and high-end devices. There is a desire from customers in the commercial market to use this capability with high-end digital presses based on electrophotographic printing (EP) technologies. However, the inherent instability of the EP process challenges the achievement of satisfactory print quality with dispersed-dot, aperiodic halftoning. The direct binary search (DBS) algorithm is widely considered to represent the gold standard of dispersed-dot, aperiodic halftone image quality.In this thesis, we adapt DBS from dispersed-dots to clustered-dots to use with the Indigo liquid EP printing technology. We present a new screen design algorithm for aperiodic, clustered-dot halftoning based on Direct Binary Search. Our screen design has a very good detail rendering capability and a very stable halftone frequencyoverall. In the next part of the thesis, we introduce a new microscreen design algorithm that allows the embedding of binary metadata in an aperiodic, clustered-dot halftone image with no loss of visual quality. We describe a simple method for decoding the embedded meta-data with only a knowledge of the two microscreens used to halftone the continuous-tone image. Our results with one image demonstrate 100% recovery of the embedded metadata. In the last part of the thesis, we introduce a method for joint design of three-color CMY screen sets, which is the continuation of the work from monochrome screen design. The method we developed was deemed to be satisfactory in all aspects of halftone texture quality as a 3-screen CMY solution.

Synthesis and ligand reactivity of group 6 organometallic nitrosyl complexe
Creators: name: Sharp, William Brett
Publisher: name: University of British Columbia
Year: 2009

description: Reaction of Cp*WR₂(NO) (R = CH₂SiMe₃ , CH₂Ph) complexes with HBF₄ yields the nitrosyl-borane adduct species Cp*WR₂ (NOBF₃) via degradation of the tetrafluoroborate counterion. The similar materials, Cp*WR₂(NOB(C₆F₅)₃), can be prepared by the addition of perfluorophenylborane to the metallonitrosyl complex. The reaction of a protic acid containing a very weakly coordinating anion ([H(OEt₂)₂][B(3,5-(CF₃)C₆H₃)₄]) with the tungsten nitrosyl species yields the first complexes containing a terminal hydroxylimido ligand, [Cp*WR₂ (NOH)]⁺. These complexes have been characterised by single crystal X-ray crystallography, and their solution behaviour has been studied by NMR spectroscopy. The dimethyl complexes, Cp*MoMe₂ (NO), have proven to be remarkably elusive synthetic targets in our laboratories. Thus, treatment of [Cp*MoCl(NO)(μ-Cl)]₂ with magnesium (Me₂Mg-dioxane, MeMgCl) or aluminum (Me₃Al) based methylating reagents leads only to metathesis of a single chloro ligand and the formation of the known compound [Cp*MoMe(NO)(μ-Cl)]₂. Similar treatment of the dichloro precursor with MeLi in ethereal solvents generates an equimolar mixture of the mono(methyl) complex and the trimethyl 'ate' complex, Cp*MoMe₃(NO-Li(OEt₂)[sub n]). In toluene at low temperatures, MeLi can be utilised to effect complete metathesis of the chloro ligands of [Cp*MoCl(NO)(μ-Cl)]₂ and generate the target dimethyl complex, Cp*MoMe₂(NO), in high yield. In solution this compound is predominantly a monomeric species similar to its more sterically encumbered congeners, whereas in the solid state it adopts a dimeric or oligomeric structure containing isonitrosyl bridges as indicated by IR and solid-state NMR spectroscopies. The reaction of the dimethyl complex with a range of Lewis bases, L, to form the 18e adducts Cp*MoMe₂L(NO), has established it to be the most electrophilic complex of its family. Most interestingly, the dimethyl complex is thermally unstable in solution and undergoes an (R-)[M](-NO) to (0=)[M](=NR) isomerisation to its oxo imido form, Cp*Mo(NMe)(O)Me, which is isolable from the final reaction mixture as the μ-oxo bridged adduct Cp*Mo(NO)Me₂(μ-O)Cp*Mo(NMe)Me. The rate of this isomerisation is significantly faster for the tungsten dimethyl complex; hence Cp*WMe₂(NO) is not isolable free of a supporting donor interaction. Under mild thermolysis conditions the tungsten complexes CpW(o-tolyl)₂(NO) undergo an aryl group isomerisation to form the mixed o-tolyl p-tolyl and o-tolyl m-tolyl complexes. The overall in-plane rotation of the tolyl group occurs via an η²-toluene η²-toluyne intermediate.

description: It is generally regarded that the bulk of cosmic rays originate in the Galaxy and that those below the 'knee' (the rapid steepening in the energy spectrum) at a few PeV come from Galactic supernovae, the particles being accelerated by the shocks in the supernova remnants. At higher energies, there are problems in that conventional SNR - which surely constitute the bulk of the sources - have a natural limit at a few tens of PeV (for iron nuclei). The question of the origin of particles above this limit is thus an open one. Here we examine a number of possibilities: a variety of supernovae and hypernovae, pulsars, a Giant Galactic Halo and an Extragalactic origin. A relevant property of any model is the extent to which it can provide the lack of significant irregularity of the energy spectrum. Although it is appreciated that spectral measurements are subject to systematic as well as random errors we consider that contemporary data are good enough to allow at least some progress in this field. In the search for origin above PeV energies we conclude that shocks in the Galactic Halo, whatever their source (Galactic wind, relativistic plasmoids - 'cannonballs', multiple shocks from supernovae etc.) are most likely, pulsrs such as B0656+14 and hypernovae come a close second although such a suggestion is not without its difficulties. What is most important is that trapping of particles in the Halo is needed to reduce irregularities of the energy spectra both below and above the 'knee' caused by the stochastic nature of supernova explosions and other potential (discrete) Galactic sources. We argue that precise experimental studies of spectral 'irregularities' will provide considerable help in the search for cosmic ray origin.

Effect of the Reynolds number on turbulence kinetic energy exchanges in flows with highly variable fluid properties

description: Spatial and spectral energy exchanges associated with the turbulence kinetic energy per unit mass, or half-trace of the velocity covariance tensor, are studied in an anisothermal low Mach number turbulent channel flow. The temperatures of the two channel walls are 293 K and 586 K. This generates a strong temperature gradient in the wall-normal direction. The effect of the temperature gradient on the energy exchanges is investigated using two direct numerical simulations of the channel, at the mean friction Reynolds numbers 180 and 395. The temperature gradient creates an asymmetry between the energy exchanges at the hot and cold sides, due to the variations of the local fluid properties and low Reynolds number effects. The low Reynolds number effects are smaller at higher Reynolds number, reducing the asymmetry between the hot and cold sides. We also decomposed the energy exchanges in order to study separately the mean-property terms, as found in the constant-property isothermal case, and the thermal terms, specific to flows with variable fluid properties. The significant thermal terms have a similar effect on the flow. Besides, low Reynolds number effects have a negligible impact on thermal terms and only affect mean-property terms.

description: The Be X-ray binary GRO J2058+42 recently went through a Type-II outburst during March-April 2019 lasting for about 50 days. This outburst was detected with the operating all sky X-ray monitors like the Fermi-GBM, Swift-BAT and MAXI-GSC. Two NuSTAR observations were also made, one during the rise and other during the decay of the outburst. It gave us the unique opportunity to analyze the broadband characteristics of the pulsar for the first time and accretion torque characteristics of the pulsar over a range of X-ray luminosity. The pulse profiles are strongly energy dependent, with at least four different pulse components at low energy (< 20 keV) which evolves to a single-peaked profile at high energy (> 30 keV). In each of the narrow energy bands, the pulse profiles are nearly identical in the two NuSTAR observations. The spectra from both the observations are fitted well to a power-law with a Fermi-Dirac type high energy cutoff. We ruled out presence of a cyclotron line in the pulse phase averaged X-ray spectrum in the NuSTAR band with an optical depth greater than 0.15. An iron emission line is detected in both the NuSTAR spectra with an equivalent width of about 125 eV. We looked at the dependence of the spin-up rate on the luminosity and estimated the magnetic field strength from that, which came out to be much higher compared to other known BeXRB pulsars. Lastly, we discussed the inadequacy of the torque-luminosity relation for determination of magnetic field strength of neutron stars.

description: Complexes incorporating the [Re=0]³⁺ core have been synthesized with ligands containing the new methyl substituted phosphine/phenolate PO and PO₂ donor sets, (2- hydroxy-5-methylphenyl)diphenylphosphine (H(MePO)) and bis(2-hydroxy-5-methylphenyl)phenylphosphine (H₂ (Me₂PO₂)). Reaction of either mer-[ReOCl₃(PPh₃)₂] or [NH₄][ReO₄] in CH₃OH with H(MePO) led to formation of [ReOCl(MePO) ₂] (2.1) in good yield. Reaction of [NH₄][ReO₄] with H₂ (Me₂PO₂) in CH₃OH afforded [ReO(Me₂PO₂)(H(Me₂PO₂))] (2.2), also in good yield. X-ray crystallographic analyses of 2.1 and 2.2 demonstrated that both complexes are neutral and octahedral, and contain the oxo moiety. The two phosphorus donors are cis to one another in 2.1 and 2.2 with a phenol donor trans to the oxo moiety. 2.2 has a tridentate Me₂PO₂ ligand as well as a bidentate H(Me₂PO₂) ligand wherein one of the phenol donors is protonated and not bound to the metal centre.

On the Size Distribution of Close-In Extrasolar Giant Planets

description: The precisions of extrasolar planet radius measurements are reaching the point at which meaningful and discriminatory comparisons with theoretical predictions are can be made. However, care must be taken to account for selection effects in the transit surveys that detect the transiting planets for which radius measurements are possible. Here I identify one such selection effect, such that the number of planets with radius R_p detected in a signal-to-noise ratio limited transit survey is proportional to R_p^alpha, with alpha~4-6. In the presence of a dispersion sigma in the intrinsic distribution of planet radii, this selection effect translates to bias b in the radii of observed planets. Detected planets are, on average, larger by a fractional amount b ~ alpha (sigma/)^2 relative to the mean radius of the underlying distribution. I argue that the intrinsic dispersion in planetary radii is likely to be in the range sigma = (0.05-0.13)R_J, where the lower bound is that expected theoretically solely from the variance in stellar insolation, and the upper bound is the 95% c.l. upper limit from the scatter in observed radii. Assuming an arbitrary but plausible value of sigma/~10%, and thus b~6%, I infer a mean intrinsic radius of close-in massive extrasolar planets of =(1.03+/-0.01)R_J. This value reinforces the case for HD209458b having an anomalously large radius, and may be inconsistent with coreless models of irradiated giant planets.

description: Consider the Klein-Gordon-Zakharov equations in $\mathbb{R}^{1+2}$, and we are interested in establishing the small global solution to the equations and in investigating the pointwise asymptotic behavior of the solution. The Klein-Gordon-Zakharov equations can be regarded as a coupled semilinear wave and Klein-Gordon system with quadratic nonlinearities which do not satisfy the null conditions, and the fact that wave components and Klein-Gordon components do not decay sufficiently fast makes it harder to conduct the analysis. In order to conquer the difficulties, we will rely on the hyperboloidal foliation method and a minor variance of the ghost weight method. As a side result of the analysis, we are also able to show the small data global existence result for a class of quasilinear wave and Klein-Gordon system violating the null conditions.
