description: We consider the dynamics of a separable Continuous Time Random Walk (CTRW) when the random walker is biased by a velocity field in a uniformly growing domain. Concrete examples for such domains include growing biological cells or lipid vesicles, biofilms and tissues, but also macroscopic systems such as expanding aquifers during rainy periods, or the expanding universe. The considered CTRW can be subdiffusive, normal diffusive or superdiffusive, including the particular case of a Lévy flight. We first consider the case of zero velocity field. In the subdiffusive case, we reveal an interesting time dependence of the kurtosis of the particle probability density function. In particular, for a suitable parameter choice, we find that the propagator, which is fat tailed at short times, may cross over to a Gaussian-like propagator. We subsequently incorporate the effect of the velocity field and derive a bi-fractional diffusion-advection equation encoding the time evolution of the particle distribution. We apply this equation to study the mixing kinetics of two diffusing pulses, whose peaks move towards each other under the action of velocity fields acting in opposite directions. This deterministic motion of the peaks, together with the diffusive spreading of each pulse, tends to increase particle mixing, thereby counteracting the peak separation induced by the domain growth. As a result of this competition, different regimes of mixing arise. In the case of Lévy flights, apart from the non-mixing regime, one has two different mixing regimes in the long-time limit, depending on the exact parameter choice: In one of these regimes, mixing is mainly driven by diffusive spreading, while in the other mixing is controlled by the velocity fields acting on each pulse. Possible implications for encounter-controlled reactions in real systems are discussed.

description: We develop measures of technical and allocative efficiency of producers in marketing certified organic products. A stochastic output distance frontier and the associated revenue share equations are estimated using comprehensive U.S. data on certified organic producers. Farm-level measures of technical efficiency are calculated and factors that enhance performance are identified. Factors that systematically influence allocative efficiency are assessed. The revenue mix of organic producers is systematically inefficient as both male and female producers rely too heavily on revenue from organic markets relative to conventional outlets.

description: Several recent papers have used annual changes and monthly data to estimate demand systems. Such use of overlapping data introduces a moving average error term. This paper shows how to obtain consistent and asymptotically efficient estimates of a demand system using seasonally differenced data. Monte Carlo simulations and an empirical application to the estimation of the U.S. meat demand are used to compare the proposed estimator with alternative estimators. Once the correct estimator is used, there is no advantage to using overlapping data in estimating a demand system.

Graviton collider effects in one and more large extra dimensions

description: Astrophysical bounds severely limit the possibility of observing collider signals of gravity with less than 3 flat extra dimensions. However, small distortions of the compactified space can lift the masses of the lightest graviton excitations, evading astrophysical bounds without affecting collider signals of quantum gravity. Following this procedure we reconsider theories with one large extra dimension. A slight space warping gives a model which is safe in the infrared against astrophysical and observational bounds, and which has the ultraviolet properties of gravity with a single flat extra dimension. We extend collider studies to the case of one extra dimension, pointing out its peculiarities. Finally, for a generic number of extra dimensions, we compare different channels in LHC searches for quantum gravity, introducing an ultraviolet cutoff as an additional parameter besides the Planck mass.

description: A recent update from MiniBooNE has strengthened the observed $4.8σ$ excess of $e$-like events. Motivated by this and other notable deviations from standard model predictions, such as the muon $(g-2)$, we propose a solution to low energy anomalies through a dark neutrino sector. The model is renormalizable and can also explain light neutrino masses with an anomaly-free and dark $U(1)^\prime$ gauge symmetry broken at the GeV scale. Large kinetic mixing leads to s-channel production of heavy neutral leptons at $e^+e^-$ colliders, where we point out and explain a $\gtrsim 2σ$ excess observed in the BaBar monophoton data. Our model is also compatible with anomalous $e$-like events seen at old accelerator experiments, as well as with an excess of double vertex signatures observed at CCFR.

description: An accumulator is a bet that presents a rather unique payout structure, in that it combines multiple bets into a wager that can generate a total payout given by the multiplication of the individual odds of its parts. These potentially important returns come however at an increased risk of a loss. Indeed, the presence of a single incorrect bet in this selection would make the whole accumulator lose. The complexity of selecting a set of matches to place an accumulator bet on, as well as the number of opportunities to identify winning combinations have both dramatically increased with the easier access to online and offline bookmakers that bettors have nowadays. We address this relatively under-studied combinatorial aspect of sports betting, and propose a binary optimization model for the problem of selecting the most promising combinations of matches, in terms of their total potential payout and probability of a win, to form an accumulator bet. The results of an ongoing computational experiment, in which our model is applied to real data pertaining to the four main football leagues in the world over a complete season, are presented and compared to those of single bet selection methods.

description: High natural gas prices have agricultural producers searching for alternative energy sources for irrigation. The economic feasibility of electric and hybrid (electric/wind) systems are evaluated as alternatives to natural gas powered irrigation. Texas Panhandle and Southern Kansas farms are assessed with a quarter-mile sprinkler system, three crops, and two pumping lifts. Breakeven points identify the price at which conversion from a natural gas irrigation system to an electric or hybrid system is cost effective. Results indicate electricity is a more feasible energy source for irrigation and policy changes such as net metering are necessary to make hybrid systems viable.

description: This study estimates the potential impacts of the Doha Development Agenda (DDA) on the Korean raw-milk market. The DDA has not reached an agreement yet. Although there are different attitudes about several issues such as Special Safeguard Mechanism (SSM), Sensitive Products (SP), and Tariff Rate Quota (TRQ) creation, WTO member countries have reached an agreement for major issues of the modalities in the DDA. Hence, this study estimates the impacts of the DDA that will finally reach an agreement sooner or later. For estimating the impacts of the DDA, this study makes a dairy trade model for the Korean dairy industry and measures the impacts of the DDA in terms of raw-milk price for fluid use incurred by further tariff cuts in the Korean dairy market by the DDA. This study considers several scenarios because the status of Korea is not settled yet and a country can select dairy products as sensitive products, special products, or general products and a country can select different options in each category. The results of this study can be used for preparing policies for subsidizing the domestic raw-milk producers to rebalance their loss in the raw-milk market incurred by the DDA.
Nontrivial Correlation between the CKM and MNS Matrices

description: We point out that the Cabibbo-Kobayashi-Maskawa (CKM) quark mixing matrix $V_{\rm CKM}$ and the Maki-Nakagawa-Sakata (MNS) lepton mixing matrix $V_{\rm MNS}$ can naturally be correlated in a class of seesaw models with grand unification, but the texture of their correlation matrix ${\cal F}_ν$ is rather nontrivial. The bimaximal mixing pattern of ${\cal F}_ν$ is disfavored by current data, and other special forms of ${\cal F}_ν$ may suffer from fine-tuning of the free phase parameters in fitting the so-called quark-lepton complementarity relation. A straightforward calculation of ${\cal F}_ν$ in terms of $V_{\rm CKM}$ and $V_{\rm MNS}$ reveals a striking feature of ${\cal F}_ν$: its (1,3) element cannot be zero or too small, no matter whether the (1,3) elements of $V_{\rm CKM}$ and $V_{\rm MNS}$ are vanishing or not. We also add some brief comments on possible radiative corrections to $V_{\rm CKM}$ and $V_{\rm MNS}$.

Cowboy up : gender and sexuality in Calgary’s "gay" and "straight" rodeo
Creators: name: Hanvelt, Jonathan
Publisher: name: University of British Columbia
Year: 2009

description: This thesis addresses varying constructions and expressions of masculinities in two of the rodeo communities in Calgary, Alberta. For this work, I focus on the rodeo produced by the Alberta Rockies Gay Rodeo Association and the one produced by the Calgary Stampede. Using a combination of participant observation and textual analysis, I examine the ways in which the institutional bodies of the rodeos, as well as some of the community members, construct and communicate definite ideas about gender and sexuality. Using Connell's concept of 'hegemonic masculinity,' I describe the Calgary Stampede as a place where the major tenets of that masculinity are represented, enacted, and thereby reinforced. This includes ideologically divided gender roles, a privileging of whiteness, and a compulsory heterosexuality. Conversely, I found the gay rodeo to be a site of great resistance to that hegemonic construct in terms of both gender and sexuality. At an institutional level, the gay rodeo produces a space that refuses to confine itself to the strict confines that are dictated in straight rodeo. This subversion is quite extensive and can even be seen as an arena in which gender is detached from the sexed subject. That is to say that under these circumstances, the broad concept of masculinity is one that is accessible to everyone, regardless of physiology. On the individual level however, we can see how the ideas that guide the production of the gay rodeo are not fully assimilated by all of the people who attend the rodeos. Within gay rodeo culture, there remains a strong presence of hyper-masculinity complete with its sexism and homophobia. This presence limits the transformative possibilities that the gay rodeo otherwise holds.
Spontaneous emission rate and the density of states inside a one dimensional photonic crystal

Publisher: name: arXiv
Year: 2021
Subjects: subject: Optics (physics.optics)

description: Different densities of electromagnetic states inside a one dimensional photonic crystal (1D PC) are studied. Hertz vector formalism is used to calculate Green tensor inside a layered structure, semi-analytically. Based on the obtained Green tensor, the local density of electromagnetic states (LDOS) and the density of states (DOS) inside a 1D PC are calculated and discussed. The Green tensor is also used to approximate the density of Bloch states inside the 1D PC and is compared with its exact calculation based on the 1D PC dispersion relations. Using a practical 1D PC parameters in the visible range, the aforementioned quantities are calculated and verified with a full-wave solver based on finite element method (FEM). The formulations and the results are aimed to be helpful in thermal and spontaneous radiation studies.

description: The relationship among rice yield and weather variables in Korea is explored using a stochastic production function. The results reveal that average rice yield is positively related to temperature and negatively associated with precipitation. Both temperature and precipitation, which are risk-increasing inputs, are positively related to rice yield variability. The widened yield variability can be transferred to the fluctuation of rice production and rice price instability. Larger market risk is expected in the future since both temperature and precipitation are anticipated to increase. An evaluation of climate change impact on rice yield variability reveals that it may increase by up to 10%~20%. Reducing yield variability and managing market risk would be the primary goals of the government's farm policy and research.

description: The comparison between the new Spitzer data at 24 micron and the previous ISOCAM data at 15 micron is a key tool to understand galaxy properties and evolution in the infrared and to interpret the observed number counts, since the combination of Spitzer with the ISO cosmological surveys provides for the first time the direct view of the Universe in the Infrared up to z~2. We present the prediction in the Spitzer 24-micron band of a phenomenological model for galaxy evolution derived from the 15-micron data. Without any ``a posteriori'' update, the model predictions seem to agree well with the recently published 24-micron extragalactic source counts, suggesting that the peak in the 24-micron counts is dominated by ``starburst'' galaxies like those detected by ISOCAM at 15 micron, but at higher redshifts (1 < z < 2 instead of 0.5 < z < 1.5).

description: This talk begins with some history and basic facts about string theory and its connections with strong interactions. Comparisons of stacks of Dirichlet branes with curved backgrounds produced by them are used to motivate the AdS/CFT correspondence between superconformal gauge theory and string theory on a product of Anti-de Sitter space and a compact manifold. The ensuing duality between semi-classical spinning strings and long gauge theory operators is briefly reviewed. Strongly coupled thermal SYM theory is explored via a black hole in 5-dimensional AdS space, which leads to explicit results for its entropy and shear viscosity. A conjectured universal lower bound on the viscosity to entropy density ratio, and its possible relation to recent results from RHIC, are discussed. Finally, some available results on string duals of confining gauge theories are briefly reviewed.

description: Private labels, also known as store brands, are an important component of competitive strategy among multi-product retailers, as they can increase retailers’ power over suppliers in the vertical channel or facilitate horizontal differentiation among retailers. This paper seeks to identify the relative importance of each role, conditional on the location of both private labels and national brands of ice cream in attribute space. We find that retailers’ share of the total margin (retail price less production cost) is higher for private labels than national brands when retailers choose to imitate national brands with their own offerings.

Based on the high-order plane wave expansion model, we derive an effective Hamiltonian which characterizes dual band gaps. Metallic valley photonic crystals are demonstrated as examples in which all four topological phases are found. At the domain walls between topologically distinct valley photonic crystals, frequency-dependent edge states are demonstrated and a broadband photonic detouring is proposed. Our findings provide the guidance for designing the frequency-dependent property of topological structures and show its potential applications in wavelength division multiplexers.

description: We study in this work the dynamics of a collection of identical hollow spheres (ping-pong balls) that rest on a horizontal metallic grid. Fluidization is achieved by means of a turbulent air current coming from below. The upflow is adjusted so that the particles do not levitate over the grid, resulting in quasi-two-dimensional dynamics. We show that the behavior of diffusion and correlations in this system is particularly rich. Noticeably as well (and related to the complex dynamical behavior), a variety of phases appear, with important peculiarities with respect to analogous setups. We observe gas, liquid, glass, and hexagonal crystal phases. Most notably, we show that the melting of the hexagonal crystal occurs in coexistence with a liquid phase. This strikingly differs from the corresponding transition in a purely two-dimensional systems of air-fluidized disks, for which no phase coexistence has been reported in the literature.

description: We propose consumption inertia as a new explanation for asymmetric price transmission. Inertia in consumer demand enlarges retailers’ gains in gross profits from raising prices in response to higher wholesale prices and reduces gains from decreasing prices in response to lower wholesale prices. Thus, consumption inertia can cause asymmetries in price transmission whereby retailers are more willing to change their prices, and change them more quickly, in response to wholesale price increases as opposed to wholesale price decreases.
Minimum Perimeter Rectangles That Enclose Congruent Non-Overlapping Circles

description: We use computational experiments to find the rectangles of minimum perimeter into which a given number n of non-overlapping congruent circles can be packed. No assumption is made on the shape of the rectangles. In many of the packings found, the circles form the usual regular square-grid or hexagonal patterns or their hybrids. However, for most values of n in the tested range n =< 5000, e.g., for n = 7, 13, 17, 21, 22, 26, 31, 37, 38, 41, 43...,4997, 4998, 4999, 5000, we prove that the optimum cannot possibly be achieved by such regular arrangements. Usually, the irregularities in the best packings found for such n are small, localized modifications to regular patterns; those irregularities are usually easy to predict. Yet for some such irregular n, the best packings found show substantial, extended irregularities which we did not anticipate. In the range we explored carefully, the optimal packings were substantially irregular only for n of the form n = k(k+1)+1, k = 3, 4, 5, 6, 7, i.e., for n = 13, 21, 31, 43, and 57. Also, we prove that the height-to-width ratio of rectangles of minimum perimeter containing packings of n congruent circles tends to 1 as n tends to infinity.
description: existence of irregular minimum perimeter packings for n not of the form (10) is conjectured; smallest such n is n=66; existence of irregular minimum area packings is conjectured, e.g. for n=453; locally optimal packings for the two minimization criteria are conjecturally the same (p.22, line 5); 27 pages, 12 figures

description: This paper examines structural breaks in the vertical price relationships in U.S. beef/cattle and pork/hog sectors using monthly data of the past 40 years. A major methodological issue addressed is how to estimate price relationships when data contain intermittent structural breaks with unknown break dates. The adopted procedures endogenously search for structural break dates while explicitly accounting for this search in statistical inferences. Four breaks for the beef/cattle price relationship and three breaks for the pork/hog price relationship are identified. The estimation results further confirm the importance of allowing for structural breaks in the analysis of vertical price relationships.

The proposed approach is applied to the evaluation of the potential economic impact of the locally grown campaign in South Carolina. Results reveal that the first season of the promotion campaign increased consumer willingness to pay for produce by 3.4%. The change in consumer preferences and the corresponding shift in demand increased producer surplus by $3.09 million. This economic benefit, combined with the 2007 promotion campaign investment, resulted in a benefit-cost ratio of 6.18.

description: Introduction: The method of choice for monitoring post-transplant rejection status for heart transplant patients is the evaluation of multiple tissue biopsies. The diagnostic technique is time consuming, costly and invasive with possible life threatening complications. The major histocompatibility complex is the most widely distributed and significant determinant for transplantation. We hypothesized that the MHC II expression on peripheral T-lymphocytes is reflective of rejection status in allotransplanted hearts. The objective of this project is to determine if MHC II expression on peripheral Tlymphocytes correlates with histological findings of rejection after transplantation. Materials and methods: The heterotopic heart transplant was performed in 24 female domestic swine, weighing 27-30 Kg. Animals were divided into two groups. Group A (6 donors + 6 recipients) was not treated with immunosuppressive therapy. In group B (6 donors + 6 recipients) immunosuppressive therapy (Cyclosporine 6mg/Kg/BID, Methylpednisolone 1.8mg/Kg/day and Azathioprine 3mg/Kg/day) was used. Cyclosporine levels in blood were maintained at 400 ng/mL. Donor animals were anaesthetisized and the heart was harvested through a median sternotomy. The hearts were antegradely perfused with isoosmolar Tyers's solution and were then preserved in a hypothermic storage for two hours at 4°C. In the postoperative period animals were monitored by ECG, heart-rate, body temperature, blood samples for MHC II expression, cyclosporine levels, CBC plus differential and creatinine daily . Animals in Group A, survived for a period of five days and animals in Group B, where immunosuppressive therapy was applied, survived for five days also. The endomyocardial biopsies (EMB) were taken from the graft's free wall, apex and septum on day one and five for both groups A and B. The evaluation of #120 EMB (biopsies) was done using modified International Society Heart and Lung Transplant Grading Scale. Results: Results of this experimental endeavour demonstrated that MHC II expression on T-lymphocytes significantly correlates with biopsy findings from apex (P<0.01; R² = 0.83) for Group A (non-immunosuppressed animals) on day five. The combined data for both Groups A and B (non-immunosuppressed and immunosuppressed animals) at this time were also correlated significantly (P<0.01; R² = 0.63) for free wall and (P=0.01; R² =0.7) for apex despite a significant difference between non-immunosuppressed and immunosuppressed animals. Conclusions: Results of this experimental protocol suggested that there is a significant correlation between MHC II expression on peripheral T-lymphocytes and Grade of rejection assessed by endomyocardial biopsy on day five after surgery. Further studies will be required to establish the long term relationship of MHC II expression on peripheral T-lymphocytes and histological findings, particularly in animals with immunosuppressive therapy.

description: A choice experiment was used to determine consumer value for verification of livestock production process attributes. Willingness to pay for verification of production process attributes varied for both milk and pork chops across attributes and verifying entity. Statistically significant evidence of social desirability bias was found by comparing estimates of consumer preferences solicited using direct and indirect questioning. Indirect questioning may yield more accurate representations of consumer value than direct questioning, and therefore more accurate estimates for agribusiness decision making.

description: Molecular Music grew out of the danceroom Spectroscopy (dS) project, an arts/science collaborative project exploring molecular dynamics allowing users to interact with a scientifically-accurate molecular simulation through movement in real time. Where this interaction was originally through movement, in Molecular Music Hyde led a project to explore interaction through sound, both in a solo audiovisual performance (Cloud Chamber) and in collaboration with other musicians.

This item contains a paper from the proceedings of the XVII Generative Art Conference, written about the project, as contextual information.

description: Representation of brain network interactions is fundamental to the translation of neural structure to brain function. As such, methodologies for mapping neural interactions into structural models, i.e., inference of functional connectome from neural recordings, are key for the study of brain networks. While multiple approaches have been proposed for functional connectomics based on statistical associations between neural activity, association does not necessarily incorporate causation. Additional approaches have been proposed to incorporate aspects of causality to turn functional connectomes into causal functional connectomes, however, these methodologies typically focus on specific aspects of causality. This warrants a systematic statistical framework for causal functional connectomics that defines the foundations of common aspects of causality. Such a framework can assist in contrasting existing approaches and to guide development of further causal methodologies. In this work, we develop such a statistical guide. In particular, we consolidate the notions of associations and representations of neural interaction, i.e., types of neural connectomics, and then describe causal modeling in the statistics literature. We particularly focus on the introduction of directed Markov graphical models as a framework through which we define the Directed Markov Property -- an essential criterion for examining the causality of proposed functional connectomes. We demonstrate how based on these notions, a comparative study of several existing approaches for finding causal functional connectivity from neural activity can be conducted. We proceed by providing an outlook ahead regarding the additional properties that future approaches could include to thoroughly address causality.

description: Two-dimensional (2D) molybdenum disulfide (MoS2) holds great promise in electronic and optoelectronic applications owing to its unique structure and intriguing properties. The intrinsic defects such as sulfur vacancies (SVs) of MoS2 nanosheets are found to be detrimental to the device efficiency. To mitigate this problem, functionalization of 2D MoS2 using thiols has emerged as one of the key strategies for engineering defects. Herein, we demonstrate an approach to controllably engineer the SVs of chemically exfoliated MoS2 nanosheets using a series of substituted thiophenols in solution. The degree of functionalization can be tuned by varying the electron withdrawing strength of substituents in thiophenols. We find that the intensity of 2LA(M) peak normalized to A1g peak strongly correlates to the degree of functionalization. Our results provide a spectroscopic indicator to monitor and quantify the defect engineering process. This method of MoS2 defect functionalization in solution also benefits the further exploration of defect free MoS2 for a wide range of applications.

description: Do non-wage fringe benefits affect women’s off-farm work decisions? We test the impact of the 1995 introduction of universal National Health Insurance (NHI) in Taiwan on off-farm labor force participation (LFP) among farm wives. Our results, based on a difference-in- differences approach, indicate that employment-delinked NHI reduced farm wives’ off-farm LFP by 9.6 to 13.6 percentage points. The larger impact was for wives from small farm households. The health insurance reform had a larger negative impact on overall LFP among married women in agricultural households than in nonagricultural households.

description: We apply the methods of C{ă}ld{ă}raru to construct a twisted Fourier-Mukai transform between a pair of holomorphic symplectic four-folds. More precisely, we obtain an equivalence between the derived category of coherent sheaves on a certain four-fold and the derived category of twisted sheaves on its `mirror' partner. As corollaries, we show that the two spaces are connected by a one-parameter family of deformations through Lagrangian fibrations, and we extend the original Fourier-Mukai transform to degenerations of abelian surfaces.
