description: Experiments investigating the fine structure of the IsoScalar Giant Monopole Resonance (ISGMR) of 48Ca were carried out with a 200 MeV alpha inelastic-scattering reaction, using the high energy-resolution capability and the zero-degree setup at the K600 magnetic spectrometer of iThemba LABS, Cape Town, South Africa. Considerable fine structure is observed in the energy region of the ISGMR. Characteristic energy scales are extracted from the experimental data by means of a wavelet analysis and compared with the state-of-the-art theoretical calculations within a Skyrme-RPA (random phase approximation) approach using the finite-rank separable approximation with the inclusion of phonon-phonon coupling (PPC). Good agreement was observed between the experimental data and the theoretical predictions.

description: We introduce spaces of exponential constructible functions in the motivic setting for which we construct direct image functors in the absolute and relative cases. This allows us to define a motivic Fourier transformation for which we get various inversion statements. We define also motivic Schwartz-Bruhat spaces on which motivic Fourier transformation induces an isomorphism. Our motivic integrals specialize to non archimedian integrals. We give a general transfer principle comparing identities between functions defined by integrals over local fields of characteristic zero, resp. positive, having the same residue field. We also prove new results about p-adic integrals of exponential functions.

description: Particles suspended in a fluid exert feedback forces that can significantly impact the flow, altering the turbulent drag and velocity fluctuations. We study flow modulation induced by particles heavier than the carrier fluid in the framework of an Eulerian two-way coupled model, where particles are represented by a continuum density transported by a compressible velocity field, exchanging momentum with the fluid phase. We implement the model in direct numerical simulations of the turbulent Kolmogorov flow, a simplified setting allowing for studying the momentum balance and the turbulent drag in the absence of boundaries. We show that the amplitude of the mean flow and the turbulence intensity are reduced by increasing particle mass loading with the consequent enhancement of the friction coefficient. Surprisingly, turbulence suppression is stronger for particles of smaller inertia. We understand such a result by mapping the equations for dusty flow, in the limit of vanishing inertia, to a Newtonian flow with an effective forcing reduced by the increase in fluid density due to the presence of particles. We also discuss the negative feedback produced by turbophoresis which mitigates the effects of particles, especially with larger inertia, on the turbulent flow.

Evidence for a Link Between Fe K-alpha Emission Line Strength and QPO Phase in a Black Hole

Publisher: name: arXiv

description: In X-ray binaries, the frequencies revealed in X-ray quasi-periodic oscillations (QPOs) are often interpreted as characteristic frequencies in the inner accretion disk, though the exact oscillation mechanism is unknown at present. Broadened Fe K-alpha lines are also excellent diagnostics of the inner accretion flow, if their broadening is indeed due to inner disk reflection. Herein, we present two cases where the flux and equivalent width of the Fe K-alpha emission lines in spectra of the Galactic black hole GRS 1915+105 vary with the phase of strong 1 Hz and 2 Hz QPOs in the X-ray flux. These results provide strong evidence that both QPOs and the Fe-alpha lines originate in the inner disk. If the 1 Hz QPO is only a Keplerian orbital frequency, the QPO comes from a distance of 84 +/- 26 R_Schw from the black hole; the 2 Hz QPO implies a radius of 50 +/- 15 R_Schw. At these radii, relativistic shaping of a disk line is inevitable. Moreover, the link holds in radio-bright and radio-faint phases, signaling that in systems like GRS 1915+105, the Fe K-alpha line is a disk line and not a jet line as per SS 433. A particularly interesting possibility is that a stable warp in the inner disk, e.g. due to Lense-Thirring precession, may produce the observed QPOs and line modulations. More broadly, the FeK-QPO link provides an unprecedented mechanism for revealing the inner accretion flow and relativistic regime in accreting systems, in that it gives two measures of radius: for a given disk QPO model, the frequency translates into a specific radius, and relativistic line models yield radii directly.

description: Arbitrary high order numerical methods for time-harmonic acoustic scattering problems originally defined on unbounded domains are constructed. This is done by coupling recently developed high order local absorbing boundary conditions (ABCs) with finite difference methods for the Helmholtz equation. These ABCs are based on exact representations of the outgoing waves by means of farfield expansions. The finite difference methods, which are constructed from a deferred-correction (DC) technique, approximate the Helmholtz equation and the ABCs, with the appropriate number of terms, to any desired order. As a result, high order numerical methods with an overall order of convergence equal to the order of the DC schemes are obtained. A detailed construction of these DC finite difference schemes is presented. Additionally, a rigorous proof of the consistency of the DC schemes with the Helmholtz equation and the ABCs in polar coordinates is also given. The results of several numerical experiments corroborate the high order convergence of the novel method.

Visions on the horizon of desire : a painting of Henry VII & his family in the presence of St. George & the dragon reconsidered
Creators: name: Milne, Margaret Wood
Publisher: name: University of British Columbia
Year: 2009

description: Bloodthirsty spectacle and devotional introspection commune together in a curious panel painting presently located at Holyrood Palace in Edinburgh. In the foreground Henry VU and his entire family kneel in prayer seemingly oblivious to St. George and the dragon waging mortal combat directly above. In the immediate centre an iridescent angel confronts the viewer with his piercing eyes. This unique panel, commissioned by Henry VU in the final years of his reign between 1503-9, has proved an enigma. With its iconographic perversity (indiscriminate borrowing from disparate artistic traditions) and stylistic eccentricities (curiously flattened and spatially disjointed figures), the Holyrood panel pushes against the boundaries of earlier visual traditions whilst rejecting renaissance paradigms manifest on the continent at this time. The reign of Henry VII itself has been seen to straddle the unstable political and cultural terrain between the Medieval and the Early Modern era. Therefore this panel provides a unique opportunity to challenge established notions regarding the intersection between vision and politics within the early Tudor court. In this thesis then, I examine the visual peculiarities presented in the Holyrood panel in order to uncover alternative viewing frameworks operative within the English court at this time. I posit pilgrimage as the structuring frame for the image with allegory as its internal dynamic. Allegory is an interpretive mode impelled by desire, which recovers meaning through the assimilation of seemingly disjunctive forms. In order to explore these allegorical trajectories within the panel, I situate the unusual configuration of St. George within an historical symbolic field. I conclude that allegory is a viable mode of political persuasion, which interpolates a predetermined viewer (here the Garter lords and knights) into a contractual relationship. Commissioned by Henry VII at a time of dynastic uncertainty and immanent death, the Holyrood panel is a political strategy that attempts to secure Tudor succession.

description: An experimental test at the intersection of quantum physics and general relativity is proposed: measurement of relativistic frame dragging and geodetic precession using intrinsic spin of electrons. The behavior of intrinsic spin in spacetime dragged and warped by a massive rotating body is an experimentally open question, hence the results of such a measurement could have important theoretical consequences. Such a measurement is possible by using mm-scale ferromagnetic gyroscopes in orbit around the Earth. Under conditions where the rotational angular momentum of a ferromagnet is sufficiently small, a ferromagnet's angular momentum is dominated by atomic electron spins and is predicted to exhibit macroscopic gyroscopic behavior. If such a ferromagnetic gyroscope is sufficiently isolated from the environment, rapid averaging of quantum uncertainty via the spin-lattice interaction enables readout of the ferromagnetic gyroscope dynamics with sufficient sensitivity to measure both the Lense-Thirring (frame dragging) and de Sitter (geodetic precession) effects due to the Earth.

description: Nearly 30 years ago, two-photon interference was observed, marking the beginning of a new quantum era. Indeed, two-photon interference has no classical analogue, giving it a distinct advantage for a range of applications. The peculiarities of quantum physics may now be used to our advantage to outperform classical computations, securely communicate information, simulate highly complex physical systems and increase the sensitivity of precise measurements. This separation from classical to quantum physics has motivated physicists to study two-particle interference for both fermionic and bosonic quantum objects. So far, two-particle interference has been observed with massive particles, among others, such as electrons and atoms, in addition to plasmons, demonstrating the extent of this effect to larger and more complex quantum systems. A wide array of novel applications to this quantum effect is to be expected in the future. This review will thus cover the progress and applications of two-photon (two-particle) interference over the last three decades.

description: Around $100 million has been spent annually on R&D and promotion in the Australian red meat industries in recent years. The R&D investments are made throughout the production, processing and marketing chain in both the grass and grain finished sectors. Promotion investments are made in both export and domestic markets. Despite this large investment of industry and government funds there is great uncertainty about the returns from these investments. Not only is it unclear what the total industry returns are but it is even less clear how producers and the community benefit from the many alternative investment options. Hence, it is unclear how funds should be allocated between these alternatives. Zhao (1999) addressed these issues in research for her PhD degree from the University of New England. An important component of this research was the development of an equilibrium displacement model of the Australian beef industry. The objective of this Report is to thoroughly document the model and the procedures followed in defining the price, quantity and market parameters (supply, demand and substitution elasticities) used in the model. The results of the base run are also reported. Twelve investment scenarios were considered relating to 1% shifts in the relevant supply or demand curves due to new technologies in individual sectors and promotion in export or domestic markets. For each scenario, total returns in terms of economic surplus gains and the distribution of total returns among individual groups, namely, among cattle producers, feedlotters, processors, exporters, retailers and domestic and overseas consumers, were estimated. Producers and domestic consumers were shown to be the main beneficiaries in all scenarios. The results indicated that, in general, producers receive larger benefit shares from on-farm research than from off-farm research. They also receive significantly larger shares from export marketing research and promotion than from domestic marketing research and promotion. In general, while they should prefer research investments over domestic promotion, they gain as large or even larger shares from export promotion than from various research scenarios.

description: This work presents the application of a new tool, Obiwan , which uses image simulations to determine the selection function of a galaxy redshift survey and calculate 3-dimensional (3D) clustering statistics. This is a forward model of the process by which images of the night sky are transformed into a 3D large--scale structure catalog. The photometric pipeline automatically detects and models galaxies and then generates a catalog of such galaxies with detailed information for each one of them, including their location, redshift and so on. Systematic biases in the imaging data are therefore imparted into the catalogs and must be accounted for in any scientific analysis of their information content. Obiwan simulates this process for samples selected from the Legacy Surveys imaging data. This imaging data will be used to select target samples for the next-generation Dark Energy Spectroscopic Instrument (DESI) experiment. Here, we apply Obiwan to a portion of the SDSS-IV extend Baryon Oscillation Spectroscopic Survey Emission Line Galaxies (ELG) sample. Systematic biases in the data are clearly identified and removed. We compare the 3D clustering results to those obtained by the map--based approach applied to the full eBOSS sample. We find the results are consistent, thereby validating the eBOSS ELG catalogs, presented in Raichoor(2020), used to obtain cosmological results.

Temperature and magnetization-dependent band-gap renormalization and optical many-body effects in diluted magnetic semiconductors

description: We calculate the Coulomb interaction induced density, temperature and magnetization dependent many-body band-gap renormalization in a typical diluted magnetic semiconductor GaMnAs in the optimally-doped metallic regime as a function of carrier density and temperature. We find a large (about 0.1 eV) band gap renormalization which is enhanced by the ferromagnetic transition. We also calculate the impurity scattering effect on the gap narrowing. We suggest that the temperature, magnetization, and density dependent band gap renormalization could be used as an experimental probe to determine the valence band or the impurity band nature of carrier ferromagnetism.

description: A coarse-graining strategy for dilute and semi-dilute solutions of interacting polymers, and of colloid polymer mixtures is briefly described. Monomer degrees of freedom are traced out to derive an effective, state dependent pair potential between the polymer centres of mass. The cross-over between good and poor solvent conditions is discussed within a scaling analysis. The method is extended to block copolymers represented as "necklaces" of soft "blobs", and its success is illustrated here in the case of a symmetric diblock copolymer which exhibits microphase separation.

description: Gamma-Ray Bursts (GRBs) fall into two classes: short-hard and long-soft bursts. The latter are now known to have X-ray and optical afterglows, to occur at cosmological distances in star-forming galaxies, and to be associated with the explosion of massive stars. In contrast, the distance scale, the energy scale, and the progenitors of short bursts have remained a mystery. Here we report the discovery of a short-hard burst whose accurate localization has led to follow-up observations that have identified the X-ray afterglow and (for the first time) the optical afterglow of a short-hard burst. These, in turn, have led to identification of the host galaxy of the burst as a late-type galaxy at z=0.16 showing that at least some short-hard bursts occur at cosmological distances in the outskirts of galaxies, and are likely to be due to the merging of compact binaries.

New insights into knocking combustion of experimental fuels

description: For almost a century, a spark ignition fuel’s knock-resisting ability is quantified with the RON and MON indications, conform the corresponding ASTM-D2699 and D2700 methods respectively. The RON/MON method requires researchers to revert to laboratories equipped with ASTM-compliant test setups when octane investigation on fuels needs to be performed. Alternative knock-resistance quantification methods have been proposed since these metrics are no longer correctly predicting the fuel’s knock-resistive behavior in modern-day spark ignition engines. Within a second-generation sustainable fuel research framework, an alternative octane rating method was developed based on cylinder pressure oscillation measurements during knocking combustion. This method, is based on the average value of the 20 highest pressure peaks of minimum 500 successive combustion cycles. It generates satisfactory results for hydrocarbon fuels, and is based on the comparison of the oscillation behavior of primary reference fuel blends with RON 90 up to RON 100. The method allows for quick octane number verification with commonly available measurement equipment in combination with a CFR engine. The method can be helpful with octane number estimations during the design of new experimental fuels. Since the method is based on pressure oscillations, it also provides insight in the high-frequency oscillation intensity with which a fuel tends to knock, and fuels that share the same octane number can be evaluated more profoundly with regards to knock-induced engine damage potential.

description: We consider the transverse-momentum ($p_T$) distribution of $Zγ$ pairs produced in hadronic collisions. Logarithmically enhanced contributions at small $p_T$ are resummed to all orders in QCD perturbation theory and combined with the fixed-order prediction. We achieve the most advanced prediction for the $Zγ$ $p_T$ spectrum by matching next-to-next-to-next-to-leading logarithmic (N$^3$LL) resummation to the integrated cross section at next-to-next-to-leading order (NNLO). By considering $\ell^+\ell^-γ$ production at the fully differential level, including spin correlations, interferences and off-shell effects, arbitrary cuts can be applied to the leptons and the photon. We present results at the LHC in presence of fiducial cuts and find agreement with the $13$\,TeV ATLAS data at the few-percent level.

Each mock catalog has a number density of $6.7 \times 10^{-4} h^3 \rm Mpc^{-3}$, covering a redshift range from 0.6 to 1.1. The mocks are calibrated to small-scale eBOSS ELG clustering measurements at scales of around 10 $h^{-1}$Mpc. The mock catalogs are generated using a combination of GaLAxy Mocks (GLAM) simulations and the Quick Particle-Mesh (QPM) method. GLAM simulations are used to generate the density field, which is then assigned dark matter halos using the QPM method. Halos are populated with galaxies using a halo occupation distribution (HOD). The resulting mocks match the survey geometry and selection function of the data, and have slightly higher number density which allows room for systematic analysis. The large-scale clustering of mocks at the baryon acoustic oscillation (BAO) scale is consistent with data and we present the correlation matrix of the mocks.

description: We extend our earlier work on cluster cores with distinct radio bubbles, adding more active bubbles, i.e. those with Ghz radio emission, to our sample, and also investigating ``ghost bubbles,'' i.e. those without GHz radio emission. We have determined k, which is the ratio of the total particle energy to that of the electrons radiating between 10 MHz and 10 GHz. Constraints on the ages of the active bubbles confirm that the ratio of the energy factor, k, to the volume filling factor, f lies within the range 1 < k/f < 1000. In the assumption that there is pressure equilibrium between the radio-emitting plasma and the surrounding thermal X-ray gas, none of the radio lobes has equipartition between the relativistic particles and the magnetic field. A Monte-Carlo simulation of the data led to the conclusion that there are not enough bubbles present in the current sample to be able to determine the shape of the population. An analysis of the ghost bubbles in our sample showed that on the whole they have higher upper limits on k/f than the active bubbles, especially when compared to those in the same cluster. A study of the Brightest 55 cluster sample shows that 17, possibly 20, clusters required some form of heating as they have a short central cooling time, t_cool < 3 Gyr, and a large central temperature drop, T_centre/T_outer< 1/2. Of these between 12 (70 per cent) and 15 (75 per cent), contain bubbles. This indicates that the duty cycle of bubbles is large in such clusters and that they can play a major role in the heating process.

Elastodynamic single-sided homogeneous Green's function representation: Theory and numerical examples

description: The homogeneous Green's function is the difference between an impulse response and its time-reversal. According to existing representation theorems, the homogeneous Green's function associated with source-receiver pairs inside a medium can be computed from measurements at a boundary enclosing the medium. However, in many applications such as seismic imaging, time-lapse monitoring, medical imaging, non-destructive testing, etc., media are only accessible from one side. A recent development of wave theory has provided a representation of the homogeneous Green's function in an elastic medium in terms of wavefield recordings at a single (open) boundary. Despite its single-sidedness, the elastodynamic homogeneous Green's function representation accounts for all orders of scattering inside the medium. We present the theory of the elastodynamic single-sided homogeneous Green's function representation and illustrate it with numerical examples for 2D laterally-invariant media. For propagating waves, the resulting homogeneous Green's functions match the exact ones within numerical precision, demonstrating the accuracy of the theory. In addition, we analyse the accuracy of the single-sided representation of the homogeneous Green's function for evanescent wave tunnelling.
Low-level and high-level motion perception in children with unilateral amblyopia
Creators: name: Paul, Pamela S.
Publisher: name: University of British Columbia

description: It has been suggested that there are two motion systems: (1) a passive, low-level motion system that automatically signals motion and has been linked to the directionally selective neurons of primary visual cortex and the medial temporal area (MT) and (2) an active, high-level motion system that is engaged by tracking the visible features of a stimulus by actively attending to it (Cavanagh, 1992). This thesis tests the possibility that the high-level motion system is selectively disrupted in amblyopia. Amblyopia is a developmental visual disorder characterised by reduced visual acuity in an otherwise healthy, properly refracted eye. It is usually associated with deficits in spatial vision. Recent work suggests that visual attention may also be disrupted and the status of motion perception is an unresolved issue. The present study assessed 13 children with unilateral amblyopia and 24 age-matched controls on one low-level motion task and four high-level motion tasks. Children with amblyopia showed similar performance to controls in both eyes (the amblyopic eye and non-amblyopic, fellow eye) on a low-level motion coherence task and two high-level motion tasks: apparent motion and visual search. Performance on a single-object tracking task was depressed in the amblyopic eye. Children with amblyopia showed depressed performance in both eyes on a multiple-object tracking task. These results suggest that there is a preservation of low-level motion perception in amblyopia, while children with amblyopia have deficits at attentively tracking multiple targets.

description: The aim of this research was to determine the economic efficiency of sweet potato production in Polish conditions (49°49′ N, 21°50′ E). The study was based on the results of a 3-year (2017-2019) f ield experiment conducted in slightly acidic brown earth. The experiment used the random subblocks method, in which the main experimental factors were cultivation technologies: A) traditional, with no cover, B) with the use of PP spunbond nonwoven. Secondary factors included 5 cultivars of sweet potato of all earliness classes (Goldstar, Carmen Rubin, Satsumo Imo, Beauregard, White Triumph). Constant organic and mineral fertilization was used, and cultivation was carried out in accordance with normal agricultural practice. The propagating material included rooted cuttings of sweet potato from in vitro propagation, planted with 50 x 75 cm spacing. The economic effect of production was determined by all experimental factors. The profitability of production was increased by the use of PP spunbond nonwoven. The most beneficial economic factors were achieved when growing the Beauregard cultivar, and the least – when growing White Triumph. The largest cost of sweet potato commercial production were sweet potato cuttings, which amounted to 56%, and the smallest – plant protection products – 1% of direct costs per 1 ha of crops. Sweet potato production in Polish soil and climate conditions between 2017–2019 turned out to be cost-effective.

description: The secular evolution of the orbital angular momentum (OAM), the systemic mass $(M=M_{1}+M_{2})$ and the orbital period of 114 chromospherically active binaries (CABs) were investigated after determining the kinematical ages of the sub-samples which were set according to OAM bins. OAMs, systemic masses and orbital periods were shown to be decreasing by the kinematical ages. The first order decreasing rates of OAM, systemic mass and orbital period have been determined as $\dot J = 3.48 \times 10^{-10} yr^{-1}$ per systemic OAM, $\dot M = 1.30 \times 10^{-10} yr^{-1}$ per systemic mass and $\dot P = 3.96\times 10^{-10} yr^{-1}$ per orbital period respectively from the kinematical ages. The ratio of $d \log J/ d \log M = 2.68$, which were derived from the kinematics of the present sample, implies that there must be a mechanism which amplifies the angular momentum loss $\bar A = 2.68$ times in comparison to isotropic angular momentum loss of hypothetical isotropic wind from the components. It has been shown that simple isotropic mass loss from the surface of a component or both components would increase the orbital period.

description: We present the final Sloan Digital Sky Survey IV (SDSS-IV) quasar catalog from Data Release 16 of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). This catalog comprises the largest selection of spectroscopically confirmed quasars to date. The full catalog includes two sub-catalogs: a "superset" of all SDSS-IV/eBOSS objects targeted as quasars containing 1,440,615 observations and a quasar-only catalog containing 750,414 quasars, including 225,082 new quasars appearing in an SDSS data release for the first time, as well as known quasars from SDSS-I/II/III. We present automated identification and redshift information for these quasars alongside data from visual inspections for 320,161 spectra. The quasar-only catalog is estimated to be 99.8% complete with 0.3% to 1.3% contamination. Automated and visual inspection redshifts are supplemented by redshifts derived via principal component analysis and emission lines. We include emission line redshifts for H$α$, H$β$, Mg II, C III], C IV, and Ly$α$. Identification and key characteristics generated by automated algorithms are presented for 99,856 Broad Absorption Line quasars and 35,686 Damped Lyman Alpha quasars. In addition to SDSS photometric data, we also present multi-wavelength data for quasars from GALEX, UKIDSS, WISE, FIRST, ROSAT/2RXS, XMM-Newton, and Gaia. Calibrated digital optical spectra for these quasars can be obtained from the SDSS Science Archive Server.

description: Difference of degeneracy of the low-spin (LS) and high-spin (HS) states causes interesting entropy effects on spin-crossover phase transitions and charge transfer phase transitions in materials composed of the spin-crossover atoms. Mechanisms of the spin-crossover (SC) phase transitions have been studied by using Wajnflasz model, where the degeneracy of the spin states (HS or LS) is taken into account and cooperative natures of the spin-crossover phase transitions have been well described. Recently, a charge transfer (CT) phase transition due to electron hopping between LS and HS sites has been studied by using a generalized Wajnflasz model. In the both systems of SC and CT, the systems have a high temperature structure (HT) and a low temperature structure (LT), and the change between them can be a smooth crossover or a discontinuous first order phase transition depending on the parameters of the systems. Although apparently the standard SC system and the CT system are very different, it is shown that both models are equivalent under a certain transformation of variables. In both systems, the structure of metastable state at low temperatures is a matter of interest. We study temperature dependence of fraction of HT systematically in a unified model, and find several structures of equilibrium and metastable states of the model as functions of system parameters. In particular, we find a reentrant type metastable branch of HT in a low temperature region, which would play an important role to study the photo-irradiated processes of related materials.

description: This study compares the economic well-being of farm and nonfarm households using data from the 2004 Agricultural Resource Management Survey and the 2004 Survey of Consumer Finances. Comparisons are made in terms of income and wealth using Tukey-Kramer mean separation tests, regression analysis, and inequality distributions. The results show that the economic well-being of households differs based on their degree of involvement in business activities and their life-cycle stages. The most interesting conclusion is that the well-being of rural residence and intermediate farms is comparable to that of wage-earning nonfarm households, while commercial farms are similar in well-being to nonfarm households with businesses.
