description: The harmonic metric for a moving Kerr black hole is presented in the second post-Minkowskian approximation. It is further demonstrated that the obtained metric is consistent with the Liénard-Wiechert gravitational potential for a moving and spinning source with an arbitrary constant velocity. Based on the metric, we also give the post-Newtonian equations of motion for photon and massive test particle in the time-dependent gravitational field.

description: The role of star formation in luminous and ultraluminous infrared galaxies is a hotly debated issue: while it is clear that starbursts play a large role in powering the IR luminosity in these galaxies, the relative importance of possible enshrouded AGNs is unknown. It is therefore important to better understand the role of star forming gas in contributing to the infrared luminosity in IR-bright galaxies. The J=3 level of 12CO lies 33K above ground and has a critical density of ~1.5 X 10^4 cm^-3. The 12CO(J=3-2) line serves as an effective tracer for warm-dense molecular gas heated by active star formation. Here we report on 12CO (J=3-2) observations of 17 starburst spirals, LIRGs and ULIRGs which we obtained with the Heinrich Hertz Submillimeter Telescope on Mt. Graham, Arizona. Our main results are the following: 1. We find a nearly linear relation between the infrared luminosity and warm-dense molecular gas such that the infrared luminosity increases as the warm-dense molecular gas to the power 0.92; We interpret this to be roughly consistent with the recent results of Gao & Solomon (2004a,b). 2. We find L_IR/M_H2 ratios ranging from ~10 to ~128 L_sun/M_sun using a standard CO-H2 conversion factor of 3 X 10^20 cm^-2 (K km s^-1)^-1. If this conversion factor is ~an order of magnitude less, as suggested in a recent statistical survey (Yao et al. 2003), then 2-3 of our objects may have significant contributions to the L_IR by dust-enshrouded AGNs.

description: We present new measurements of the quasar autocorrelation from a sample of \~80,000 photometrically-classified quasars taken from SDSS DR1. We find a best-fit model of $ω(θ) = (0.066\pm^{0.026}_{0.024})θ^{-(0.98\pm0.15)}$ for the angular autocorrelation, consistent with estimates from spectroscopic quasar surveys. We show that only models with little or no evolution in the clustering of quasars in comoving coordinates since z~1.4 can recover a scale-length consistent with local galaxies and Active Galactic Nuclei (AGNs). A model with little evolution of quasar clustering in comoving coordinates is best explained in the current cosmological paradigm by rapid evolution in quasar bias. We show that quasar biasing must have changed from b_Q~3 at a (photometric) redshift of z=2.2 to b_Q~1.2-1.3 by z=0.75. Such a rapid increase with redshift in biasing implies that quasars at z~2 cannot be the progenitors of modern L* objects, rather they must now reside in dense environments, such as clusters. Similarly, the duration of the UVX quasar phase must be short enough to explain why local UVX quasars reside in essentially unbiased structures. Our estimates of b_Q are in good agreement with recent spectroscopic results, which demonstrate the implied evolution in b_Q is consistent with quasars inhabiting halos of similar mass at every redshift. Treating quasar clustering as a function of both redshift and luminosity, we find no evidence for luminosity dependence in quasar clustering, and that redshift evolution thus affects quasar clustering more than changes in quasars' luminosity. We provide a new method for quantifying stellar contamination in photometrically-classified quasar catalogs via the correlation function.

Trade on the Mesoamerican frontier : evaluating the significance of blue-green stones at La Quemada, Zacatecas, Mexico
Creators: name: Berney, Christine
Publisher: name: University of British Columbia
Year: 2009

description: The movement of Pre-Columbian turquoise from the American Southwest to Mesoamerica has long been considered an important factor in the emergence of complex societies in North and Northwest Mexico, including the one at La Quemada. This movement is often interpreted as an expansionary process involving the acquisition o f rare resources by Central Mexican empires. I evaluated the proposition that turquoise was an important item for exchange and o f personal wealth and status at La Quemada by examining the intrasite distribution of blue-green stones from excavated contexts. My analysis suggests that although turquoise was a precious and restricted good at the site, it was not valued locally for reasons associated with large-scale political economy. This study does not minimize the importance of turquoise exchange, but raises doubts about the turquoise trade as a primary factor in the development of some northern sites, and is a step toward understanding why blue-green stones may have circulated.

description: We study open B-model representing D-branes on 2-cycles of local Calabi--Yau geometries. To this end we work out a reduction technique linking D-branes partition functions and multi-matrix models in the case of conifold geometries so that the matrix potential is related to the complex moduli of the conifold. We study the geometric engineering of the multi-matrix models and focus on two-matrix models with bilinear couplings. We show how to solve this models in an exact way, without resorting to the customary saddle point/large N approximation. The method consists of solving the quantum equations of motion and using the flow equations of the underlying integrable hierarchy to derive explicit expressions for correlators. Finally we show how to incorporate in this formalism the description of several group of D-branes wrapped around different cycles.

description: ピアノ楽曲を演奏するためには,習得するための練習が必要である.特に,成 人してからピアノをより上達させようとする人は,仕事などで練習時間がとりに くくなるため,効率よく練習をすることが必要になる. 既存研究では,上達のためにアドバイス文を呈示したり演奏情報を鍵盤上に投 影するシステムなどが存在する.しかし我々は,システムによる情報提示は事実 のみにし,その解釈や判断はユーザに委ねるべきだと考えている.理由としては, 万が一不適切なアドバイスが出力されてしまい,ユーザがシステムのアドバイス に不信感を抱いたら,モチベーションが低下する危険性が有ることなどが挙げら れる. 本研究では,上記の考えに基づき,演奏に対して楽譜どおり弾かなかった箇所 とテンポの変動のみを表示するシステムの開発を行う.ユーザはこれらの情報か ら,練習すべき箇所などを自ら判断し,効率的な練習を模索することを期待する. 評価実験では,12 人の被験者を 2 つのグループに分けて行った.システムで演 奏結果のフィードバックを見て練習する条件 1 の被験者と,フィードバックを見 ずに練習する条件 2 の被験者で,弾き間違えた音の数(Miss-note),余分に弾い た音の数(Extra-note),テンポの安定性の変動を比べ,システムの有意性を確か めた.実験の結果,弾き損ねた音の数は条件 1,2 ともに減少傾向が見られた.こ れは練習をくり返したためだと考えられる.余分に弾いた音の数は条件 1 では強 いマイナスの相関が見られたが,条件 2 ではほぼ相関が見られなかった.テンポ の変動については,有意な差は得られなかったが,双方概ね 5 回目は 1 回目に比べてテンポの安定性は増していた.また,被験者たちの中には 1 回目から 5 回目ま で両手で弾いた人・すべてを片手で弾いた人・途中から両手で弾いた人などがい たため,両手で弾いた人のみを比較した.その結果,条件 1 の弾き損ねた音符数 の T 検定の P 値はわずかに 0.05 を切らなかったが,有意傾向が見られた.条件 2 の方は有意差はなかった.余分に弾いた音の数は条件 1 の方が相関係数の平均は 少ない.テンポの安定性は 5 回目は 1 回目に比べて有意にテンポのバラつきが小 さくなっている.どの分析にせよ,両手のみだと人数が 4:3 になってしまうため, 今後人数を増やして再検討する必要がある. 実験後には自身のピアノ歴やシステムについてのアンケートに答えてもらった. システムを使用した 6 人にシステムに関する設問に答えてもらったところ,アン ケートは概ね好評だった.

description: We investigate the coherent electron-positron pair creation by high-energy photons in a periodically deformed single crystal with a complex base. The formula for the corresponding differential cross-section is derived for an arbitrary deformation field. The conditions are specified under which the influence of the deformation is considerable. The case is considered in detail when the photon enters into the crystal at small angles with respect to a crystallographic axis. The results of the numerical calculations are presented for $\mathrm{SiO}_{2}$ single crystal and Moliere parametrization of the screened atomic potentials in the case of the deformation field generated by the acoustic wave of $S$ type. In dependence of the parameters, the presence of deformation can either enhance or reduce the pair creation cross-section. This can be used to control the parameters of the positron sources for storage rings and colliders.

description: Shared mobility-on-demand services are expanding rapidly in cities around the world. As a prominent example, app-based ridesourcing is becoming an integral part of many urban transportation ecosystems. Despite the centrality, limited public availability of detailed temporal and spatial data on ridesourcing trips has limited research on how new services interact with traditional mobility options and how they impact travel in cities. Improving data-sharing agreements are opening unprecedented opportunities for research in this area. This study examines emerging patterns of mobility using recently released City of Chicago public ridesourcing data. The detailed spatio-temporal ridesourcing data are matched with weather, transit, and taxi data to gain a deeper understanding of ridesourcings role in Chicagos mobility system. The goal is to investigate the systematic variations in patronage of ride-hailing. K-prototypes is utilized to detect user segments owing to its ability to accept mixed variable data types. An extension of the K-means algorithm, its output is a classification of the data into several clusters called prototypes. Six ridesourcing prototypes are identified and discussed based on significant differences in relation to adverse weather conditions, competition with alternative modes, location and timing of use, and tendency for ridesplitting. The paper discusses implications of the identified clusters related to affordability, equity and competition with transit.

description: The prospects of indirect detection of dark matter at the galactic center depend sensitively on the mass profile within the inner parsec. We calculate the distribution of dark matter on sub-parsec scales by integrating the time-dependent Fokker-Planck equation, including the effects of self-annihilations, scattering of dark matter particles by stars, and capture in the supermassive black hole. We consider a variety of initial dark matter distributions, including models with very high densities ("spikes") near the black hole, and models with "adiabatic compression" of the baryons. The annihilation signal after 10 Gyr is found to be substantially reduced from its initial value, but in dark matter models with an initial spike, order-of-magnitude enhancements can persist compared with the rate in spike-free models, with important implications for indirect dark matter searches with GLAST and Air Cherenkov Telescopes like HESS and CANGAROO.

description: We analyze the ordering dynamics of the voter model in different classes of complex networks. We observe that whether the voter dynamics orders the system depends on the effective dimensionality of the interaction networks. We also find that when there is no ordering in the system, the average survival time of metastable states in finite networks decreases with network disorder and degree heterogeneity. The existence of hubs in the network modifies the linear system size scaling law of the survival time. The size of an ordered domain is sensitive to the network disorder and the average connectivity, decreasing with both; however it seems not to depend on network size and degree heterogeneity.

description: We study step bunching under conditions of attachment/detachment limited kinetics in the presence of a deposition or sublimation flux, which leads to bunch motion. Analysis of the discrete step dynamics reveals that the bunch velocity is inversely proportional to the bunch size for general step-step interactions. The shape of steadily moving bunches is studied within a continuum theory, and analytic expressions for the bunch profile are derived. Scaling laws obtained previously for non-moving bunches are recovered asymptotically, but singularities of the static theory are removed and strong corrections to scaling are found. The size of the largest terrace between two bunches is identified as a central scaling parameter. Our theory applies to a large class of bunching instabilities, including sublimation with attachment asymmetry and surface electromigration in the presence of sublimation or growth.

description: The paper discusses trends in ownership concentration in three principal stages of the food system: food retailing, food manufacturing, and selected inputs purchased by agricultural producers and by food processors. In each of these levels, the available information from North America, Western Europe, or global sources shows that sales concentration is increasing. An attempt is then made to assess the impact on performance of these concentration trends for final consumers and to a lesser extent for agricultural producers. Performance measures most of interest are the traditional ones derived from economic welfare analysis of imperfect competition. Market performance is analyzed one level at a time but the more difficult arena of vertical subsector performance is also examined. The current role played by public policies in ameliorating consumer and producer welfare as it is affected by the exercise of market power is also assessed. In general, competition laws that apply to horizontal conduct are more settled and more easily enforced than are public policies directed at vertical strategic conduct.

description: When a gas in an externally imposed potential field is compressed, temperature gradients appear. This has been called the piezothermal effect. It is possible to analytically calculate the time-dependent behavior of the piezothermal effect using a linearized fluid model. Quantitative differences between the fluid-model results and previous numerical calculations can be explained by the effects of viscosity and heat conductivity. The fluid model casts the piezothermal effect as a spectrum of buoyancy oscillations, which yields new physical insights into the effect.

description: On 2018, April 29, a bright classical nova (CN) Per 2018 was discovered. Its progenitor is a well-known dwarf nova V392 Per. In this contribution, we analyze $UBVR_{C}I_{C}$ photometry and optical spectroscopy of the CN V392 Per. From the $V$ light curve (LC) we found the brightness decline times t$_{2,V}$ = 3 d, t$_{3,V}$ = 10 d and calculated absolute magnitude of the nova at maximum $MV_{max}$ = -9.30 ${\pm}$0.57 using the new $MV_{max}$ - t$_{3}$ "universal" decline law and $MV_{15}$ relations, adopting the Gaia data for CNe. We determined the colour excess $E_{B-V}$ = 0.90$\pm$0.09 and distance to the nova $d$ = 3.55$\pm$0.6 kpc. The optical spectrum obtained in brightness maximum resembles that of the F2 supergiant. Its bolometric luminosity computed by fitting the continuum by atmospheric and black-body models is in agreement with the luminosity, that we have found from photometry. We estimated the mass of the ONe white dwarf in V392 Per as $M_{wd}$ = 1.21 M$_{\odot}$. The CN Per 2018 can be classified as a fast super-Eddington nova with an outburst LC of plateau type. Nova displayed He/N spectrum classification, large expansion velocities, and triple-peaked emission-line profiles during the decline, explained by equatorial ring seen nearly face on and a bipolar flow aligned almost with the line of sight. The post maximum spectra of CN Per 2018 and available radio data were used to estimate the inclination angle of the system as $i\sim$ 9$^{\circ}$. The difference in intensity of redward and blueward emission bumps is possible to explain by about 1.5 times higher density of the receding outtflow. The rapid increase of the bipolar outflow radial velocities by $\sim$300 km/s around day 5 after the maximum was caused by the fast bipolar winds from the burning white dwarf after shrinking of its pseudophotosphere.

description: We present a generalisation of surface photometry to the higher-order moments of the line-of-sight velocity distribution of galaxies observed with integral-field spectrographs. The generalisation follows the approach of surface photometry by determining the best fitting ellipses along which the profiles of the moments can be extracted and analysed by means of harmonic expansion. The assumption for the odd moments (e.g. mean velocity) is that the profile along an ellipse satisfies a simple cosine law. The assumption for the even moments (e.g velocity dispersion) is that the profile is constant, as it is used in surface photometry. We find that velocity profiles extracted along ellipses of early-type galaxies are well represented by the simple cosine law (with 2% accuracy), while possible deviations are carried in the fifth harmonic term which is sensitive to the existence of multiple kinematic components, and has some analogy to the shape parameter of photometry. We compare the properties of the kinematic and photometric ellipses and find that they are often very similar. Finally, we offer a characterisation of the main velocity structures based only on the kinemetric parameters which can be used to quantify the features in velocity maps (abridged).

description: Fresh Juice Inc. (FJI) is in the process of determining whether they should launch a new fruit juice in a market that has been relatively stagnant for the last 15 years. Management of FJI is faced with uncertainty surrounding market share, market size, price, and competitor entry. In addition, FJI has the ability to chose between alternative production processes; this choice directly affects the likelihood the investment will return a positive Net Present Value. This case teaches students how to develop a stochastic simulation models given limited information to analyze risk investment decisions

Risk and Uncertainty

description: Producers' risk perceptions, as well as their empirical measurement, have been an on-going concern for agricultural economists. Identification and categorization of producers' risk attitudes is important in both research and extension contexts. This study explores some alternative measures of farmers' attitudes and their relationships with observed producer behavior. The effect of farmers' personality types, as derived from the Myers-Briggs personality type indicator test, on marketing behavior is also explored. There were positive and statistically significant correlations of producers' risk attitudes in various areas of the farm business. However, there are also some differences in producers' willingness to risk, especially in the finance area. Although a number of variables were statistically significant, farm operator characteristics, characteristics of the farm operation and risk attitudes of the farm operator had little effect on measures of behavior thought to involve risk/return trade-offs. The Myers-Briggs personality types were used in an analysis of marketing behavior that focused on marketing tools other than the spot (cash) market. Although some of the personality types had significant effects, there were often differences between the marketing behavior associated with corn and soybeans.

description: (abridged) We study the mass assembly history (MAH) of dark matter haloes. We compare MAHs obtained using (i) merger trees constructed with the extended Press-Schechter (EPS) formalism, (ii) numerical simulations, and (iii) the Lagrangian perturbation code PINOCCHIO. We show that the PINOCCHIO MAHs are in excellent agreement with those obtained using numerical simulations. Using a suite of 55 PINOCCHIO simulations, with 256^3 particles each, we study the MAHs of 12,924 cold dark matter haloes in a \LambdaCDM concordance cosmology. We show that haloes less massive than the characteristic non-linear mass scale establish their potential wells much before they acquire most of their mass. The time when a halo reaches its maximum virial velocity roughly divides its mass assembly into two phases, a fast accretion phase which is dominated by major mergers, and a slow accretion phase dominated by minor mergers. Each halo experiences about 3 \pm 2 major mergers since its main progenitor had a mass equal to one percent of the final halo mass. This major merger statistic is found to be virtually independent of halo mass. However, the average redshift at which these major mergers occur, is strongly mass dependent, with more massive haloes experiencing their major mergers later.

description: Agricultural lenders in today's environment face many challenges when evaluating the creditworthiness of farm borrowers. To address these challenges, a survey was conducted with financial institutions in Kansas and Indiana where agricultural lenders were asked for their response to hypothetical agricultural loan requests. Each loan request differed by the borrower's character, financial record keeping, productive standing, Fair Isaac credit bureau score, and credit risk. Lenders provided information about themselves and their financial institutions. The survey data obtained determine the relative importance of financial and non-financial information when analyzing agricultural loan applications. Tobit models are estimated to identify the borrower and lender characteristics that are important in determining loan approval while OLS models are used to investigate the factors that affect interest rates offered to farm borrowers. The results provide a comparison of agricultural lending between two important agricultural states. The results from this analysis also provide lenders with insight on the factors that influence the decision making process of other agricultural lenders
“She’ll be fine”: the pregnancy mortality gap and the influence of beliefs and empathy on pregnancy treatment
Creators: name: Hatton, Vanessa

description: Black women are three to four times more likely to die due to pregnancy-related causes than White women, and experience greater maternal health complications, including increased infant mortality rates. While research documents the role of doctors’ racial and gender biases in the treatment of pain, cancer, and other health complications, limited research examines these biases in the context of pregnancy treatment. Further, these studies neglect the interaction between gender and race to form unique biases specific to a particular group, or individuals with “intersecting” identities. The present study examined the influence that the gendered and racialized stereotypes specific to Black women have on the medical treatment of pregnant women among White laypersons (N = 278) instructed to imagine that they are a physician. Further, this study examined the additional role that empathy biases play in the treatment of pregnant women. I predicted that participants randomly assigned to treat a Black pregnant target (versus a White pregnant target) would view the target in ways consistent with stereotypes about Black women, which would in turn decrease their empathy for this target, and therefore lead participants to view the Black pregnant target’s symptoms as less severe than the White pregnant target. Results of the present experiment revealed a nonsignificant overall relationship between target patient race and symptom severity ratings via an internalized model, but a significant indirect relationship between target patient race and symptom severity ratings as mediated through externalized archetype endorsement (M1) and externalized empathy (M2) via an externalized (projective) model. I suggest that these findings demonstrate that 1) racialized and gendered stereotypes can influence levels of empathy for an individual, and 2) empathy influenced via participant biases and/or perceptions of their patient can influence treatment outcomes for their target patient. Future studies should further elucidate the racialized and gendered stereotypes that influence perceptions of Black women, and the ways that these perceptions influence the medical treatment of Black women (outside of the realm of pain) using methodology that includes in-person studies.

description: Both market structure and corporate practices of Archer Daniels Midland fostered the implementation of the largest price-fixing conspiracies seen in modern times. The overcharges imposed on U.S. buyers of lysine and citric acid during 1994-1995 by ADM and its co-conspirators amounted to at least $250 million, and the total amount of public penalties, private damages, and legal costs exceeds $740 million. Perpetrators of price-fixing now face monetary exposures that are five times the amount of the harm caused to buyers. These events have spurred renewed attention by U.S. antitrust authorities in prosecuting international cartels.

description: Landauer's formula relates the conductance of a quantum wire or interface to transmission probabilities. Total transmission probabilities are frequently calculated using Green function techniques and an expression first derived by Caroli. Alternatively, partial transmission probabilities can be calculated from the scattering wave functions that are obtained by matching the wave functions in the scattering region to the Bloch modes of ideal bulk leads. An elegant technique for doing this, formulated originally by Ando, is here generalized to any Hamiltonian that can be represented in tight-binding form. A more compact expression for the transmission matrix elements is derived and it is shown how all the Green function results can be derived from the mode matching technique. We illustrate this for a simple model which can be studied analytically, and for an Fe|vacuum|Fe tunnel junction which we study using first-principles calculations.

description: The capture of photoexcited deep-band hot carriers, excited by photons with energies far above the bandgap, is of significant importance for photovoltaic and photoelectronic applications since it is directly related to the quantum efficiency of photon-to-electron conversion. By employing time-resolved photoluminescence and state-of-the-art time-domain density functional theory, we reveal that photoexcited hot carriers in organic-inorganic hybrid perovskites prefer a zigzag interfacial charge-transfer pathway, i.e., the hot carriers transfer back and forth between CH3NH3PbI3 and graphene, before they reach a charge separated state. Driven by quantum coherence and interlayer vibrational modes, this pathway at the semiconductor-graphene interface takes about 400 femtoseconds, much faster than the relaxation process within CH3NH3PbI3 (in several picoseconds). We further demonstrate that the transfer rate of the pathway can be further enhanced by interfacial defects. Our work provides a new insight for the fundamental understanding and precise manipulation of hot-carrier dynamics at the complex semiconductor-graphene interfaces, paving the way for highly efficient photovoltaic and photoelectric device optimization.

description: Soybean production in narrow rows is not a novel idea. Wiggans (1939) reported yield advantages of drilled soybeans in narrow rows (8-inches) over soybeans planted in 28-inch rows. However, farmers, consultants, and extension agents face a bewildering array of information regarding optimal row widths intended to maximize return from corn and soybeans during a growing cycle. This information is further complicated by the choices of planting equipment specialized for certain row widths. That soybeans planted in narrow rows generally out-yield soybean produced in wider rows is well documented. However, what is not clear is which narrow row width consistently and significantly outperforms other widths, yield-wise and return-wise, in which regions (Devlin et al., 1995).
The cytoplasm of living cells: A functional mixture of thousands of components

description: Inside every living cell is the cytoplasm: a fluid mixture of thousands of different macromolecules, predominantly proteins. This mixture is where most of the biochemistry occurs that enables living cells to function, and it is perhaps the most complex liquid on earth. Here we take an inventory of what is actually in this mixture. Recent genome-sequencing work has given us for the first time at least some information on all of these thousands of components. Having done so we consider two physical phenomena in the cytoplasm: diffusion and possible phase separation. Diffusion is slower in the highly crowded cytoplasm than in dilute solution. Reasonable estimates of this slowdown can be obtained and their consequences explored, for example, monomer-dimer equilibria are established approximately twenty times slower than in a dilute solution. Phase separation in all except exceptional cells appears not to be a problem, despite the high density and so strong protein-protein interactions present. We suggest that this may be partially a byproduct of the evolution of other properties, and partially a result of the huge number of components present.
