description: We present a highly efficient method for the numerical solution of coupled Gross-Pitaevskii equations describing the evolution dynamics of a multispecies mixture of Bose-Einstein condensates in time-dependent potentials. This method, based on a grid-scaling technique, compares favorably to a more standard but much more computationally expensive solution based on a frozen-resolution grid. It allows an accurate description of the long-time behavior of interacting, multi-species quantum mixtures including the challenging problem of long free expansions relevant for microgravity and space experiments. We demonstrate a successful comparison to experimental measurements of a binary Rb-K mixture recently performed with the payload of a sounding rocket experiment.

description: This paper studies Anglo-Dutch premium auctions used in the secondary market for financial securities in eighteenth-century Amsterdam, Europe's financial capital at the time. An Anglo-Dutch premium auction consists of an English auction followed by a Dutch auction, with a cash premium paid to the winner of the first round regardless of the second-round outcome. To rationalize the introduction and continued use of this auction format, we need to determine whether bidding behavior was consistent with equilibrium play. We model this auction format theoretically, and show that the likelihood of a bid in the second round should be higher when there is greater uncertainty about the value of the security being sold. We then test this prediction on data from 16,854 securities sold at auction on 469 days over an 18-year period in the late 1700s; using several different proxies for the uncertainty of a given security's value, we find support for this theoretical prediction.

Effects of Compton Cooling on Outflow in a Two Component Accretion Flow around a Black Hole: Results of a Coupled Monte Carlo-TVD Simulation

description: We wish to investigate the effects of cooling of the Compton cloud on the outflow formation rate in an accretion disk around a black hole. We carry out a time dependent numerical simulation where both the hydrodynamics and the radiative transfer processes are coupled together. We consider a two-component accretion flow in which the Keplerian disk is immersed into an accreting low-angular momentum flow (halo) around a black hole. The soft photons which originate from the Keplerian disk are inverse-Comptonized by the electrons in the halo and the region between the centrifugal pressure supported shocks and the horizon. We run several cases by changing the rate of the Keplerian disk and see the effects on the shock location and properties of the outflow and the spectrum. We show that as a result of Comptonization of the Compton cloud, the cloud becomes cooler with the increase in the Keplerian disk rate. As the resultant thermal pressure is reduced, the post-shock region collapses and the outflow rate is also reduced. Since the hard radiation is produced from the post-shock region, and the spectral slope increases with the reduction of the electron temperature, the cooling produces softer spectrum. We thus find a direct correlation between the spectral states and the outflow rates of an accreting black hole.

description: This paper evaluates the effects of a high school curriculum reform on students’ probability to enroll at university and to choose Science, Technology, Engineering or Mathematics (STEM) as college major. The reform that was introduced in one German state increased the degree of difficulty to graduate from high school by increasing the mandatory instruction time in the core subjects German, a foreign language, mathematics and natural sciences and by raising the graduation requirements. Based on administrative data covering all students, the empirical analysis is carried out by applying a difference- in-differences model. The results show that the reform increased university enrollment rates for both gender. With regard to choosing STEM as college major, we only find a robust positive effect for males.
title: An exploratory statistical analysis of the ground water in the Abbotsford-Sumas aquifer
Creators: name: Gelinas, Sharon
Publisher: name: Western Washington University
Year: 2000

description:
The Abbotsford-Sumas aquifer is a primarily unconfined aquifer, located in Whatcom County, WA, with a history of nitrate contamination. Whatcom County is a large producer of raspberries and contains numerous dairy farms. Both of these agricultural practices involve large quantities of nitrates being produced or used for fertilization. A two-year ground water monitoring program was conducted in 1997 and 1998 by Western Washington University in order to determine the spatial and temporal extent of the nitrate contamination. Possible trends in nitrate concentrations may be associated with ground water movement, chemical and biological nitrate reduction processes, seasonality and land use. Exploratory univariate, bivariate and multivariate statistical analyses were utilized to determine the dominant processes affecting nitrate concentrations in the study area. Nitrate concentrations in shallow wells were associated with local agricultural practices and nitrate concentrations in deeper wells were associated with agricultural practices occurring up-gradient in Canada. Differentiating land use based on nitrate concentrations was determined to be inconclusive. Denitrification was occurring in over half of the wells in the study area. Several types of nitrate concentration trends were observed: higher nitrate concentrations in the fall and winter due to nitrification in the spring and summer; higher nitrate concentrations in the spring and summer due to nitrogen inputs; a steady increase or decrease in nitrate concentrations; no detectable nitrate concentration. Multivariate statistical analyses confirmed that there was not one dominant process affecting nitrate concentrations in the Abbotsford-Sumas study area; therefore, nitrate concentration trends are due to a combination of processes.

description: A theoretical particle-number conserving quantum field theory based on the concept of imaginary time is presented and applied to the scenario of a coherent atomic laser field at ultra-cold temperatures. The proposed theoretical model describes the analytical derivation of the frequency comb spectrum for an atomic laser realized from modeling a coherent atomic beam of condensate and non-condensate quantum field components released from a trapped Bose-Einstein condensate at a given repetition phase and frequency. The condensate part of the atomic vapor is assumed to be subjected to thermal noise induced by the temperature of the surrounding thermal atomic cloud. This new quantum approach uses time periodicity and an orthogonal decomposition of the quantum field in a complex-valued quantum field representation to derive and model the quantum field's forward- and backward-propagating components as a standing wave field in the same unique time and temperature domain without quantitative singularities at finite temperatures. The complex-valued atom laser field, the resulting frequency comb, and the repetition frequency distribution with the varying shape of envelopes are numerically monitored within a Monte-Carlo sampling method, as a function of temperature and trap frequency of the external confinement.

description: We describe the implementation of a search for gravitational waves from compact binary coalescences in LIGO and Virgo data. This all-sky, all-time, multi-detector search for binary coalescence has been used to search data taken in recent LIGO and Virgo runs. The search is built around a matched filter analysis of the data, augmented by numerous signal consistency tests designed to distinguish artifacts of non-Gaussian detector noise from potential detections. We demonstrate the search performance using Gaussian noise and data from the fifth LIGO science run and demonstrate that the signal consistency tests are capable of mitigating the effect of non-Gaussian noise and providing a sensitivity comparable to that achieved in Gaussian noise.

description: Understanding the origin and structure of mean magnetic fields in astrophysical conditions is a major challenge. Shear flows often coexist in such astrophysical conditions and the role of flow shear on dynamo mechanism is only beginning to be investigated. Here, we present a direct numerical simulation (DNS) study of the effect of flow shear on dynamo instability for a variety of base flows with controllable mirror symmetry (i.e, fluid helicity). Our observations suggest that for helical base flow, the effect of shear is to suppress the small scale dynamo (SSD) action, i.e, shear helps the large scale magnetic field to manifest itself by suppressing SSD action. For non-helical base flows, flow shear has the opposite effect of amplifying the small-scale dynamo action. The magnetic energy growth rate ($γ$) for non-helical base flows are found to follow an algebraic nature of the form, $γ= - aS + bS^\frac{2}{3}$ , where a, b > 0 are real constants and S is the shear flow strength and $γ$ is found to be independent of scale of flow shear. Studies with different shear profiles and shear scale lengths for non-helical base flows have been performed to test the universality of our finding.

Effects of Dipole-Dipole Interaction on the Transmitted spectrum of Two-level Atoms trapped in an optical cavity

description: The transmission spectrum of two dipole-dipole coupled atoms interacting with a single-mode optical cavity in strong coupling regime is investigated theoretically for the lower and higher excitation cases, respectively. The dressed states containing the dipole-dipole interaction (DDI) are obtained by transforming the two-atom system into an effective single-atom one. We found that the DDI can enhance the effects resulting from the positive atom-cavity detunings but weaken them for the negative detunings cases for lower excitation, which can promote the spectrum exhibiting two asymmetric peaks and shift the heights and the positions of them. For the higher excitation cases, DDI can augment the atomic saturation and lead to the deforming of the spectrum. Furthermore, the large DDI can make the atom and the cavity decouple, making a singlet of the normal-mode spectrum.

Monetary and Macroprudential Policy in an Estimated DSGE Model of the Euro Area

description: In this paper, we study the optimal mix of monetary and macroprudential policies in an estimated two-country model of the euro area. The model includes real, nominal and nancial frictions, and hence both monetary and macroprudential policy can play a role. We nd that the introduction of a macroprudential rule would help in reducing macroeconomic volatility, improve welfare, and partially substitute for the lack of national monetary policies. Macroprudential policy would always increase the welfare of savers, but their e¤ects on borrowers depend on the shock that hits the economy. In particular, macroprudential policy may entail welfare costs for borrowers under technology shocks, by increasing the countercyclical behavior of lending spreads.

description: We find under some mild assumptions that the most general potential of 1-dimensional conformal systems with time independent couplings is expressed as $V=V_0+V_1$, where $V_0$ is a homogeneous function with respect to a homothetic motion in configuration space and $V_1$ is determined from an equation with source a homothetic potential. Such systems admit at most an $SL(2,\bR)$ conformal symmetry which, depending on the couplings, is embedded in Diff(R)$ in three different ways. In one case, $SL(2,\bR)$ is also embedded in Diff(S^1). Examples of such models include those with potential $V=αx^2+βx^{-2}$ for arbitrary couplings $α$ and $β$, the Calogero models with harmonic oscillator couplings and non-linear models with suitable metrics and potentials. In addition, we give the conditions on the couplings for a class of gauge theories to admit a $SL(2,\bR)$ conformal symmetry. We present examples of such systems with general gauge groups and global symmetries that include the isometries of $AdS_2 x S^3$ and $AdS_2 x S^3 x S^3$ which arise as backgrounds in $AdS_2/CFT_1$.

description: We present experimental and theoretical evidence of novel bound state formation in the low transverse field ordered phase of the quasi-one-dimensional Ising-like material CoNb$_2$O$_6$. High resolution single crystal inelastic neutron scattering measurements observe that small transverse fields lead to a breakup of the spectrum into three parts, each evolving very differently upon increasing field. This can be naturally understood starting from the excitations of the ordered phase of the transverse field Ising model, domain wall quasiparticles (solitons). Here, the transverse field and a staggered off-diagonal exchange create one-soliton hopping terms with opposite signs. We show that this leads to a rich spectrum and a special field, when the strengths of the off-diagonal exchange and transverse field match, at which solitons become localized; the highest field investigated is very close to this special regime. We solve this case analytically and find three two-soliton continua, along with three novel bound states. Perturbing away from this novel localized limit, we find very good qualitative agreement with the experimental data. We also present calculations using exact diagonalization of a recently refined Hamiltonian model for CoNb$_2$O$_6$ and using diagonalization of the two-soliton subspace, both of which provide a quantitative agreement with the observed spectrum. The theoretical models qualitatively and quantitatively capture a variety of non-trivial features in the observed spectrum, providing insight into the underlying physics of bound state formation.

description: We propose a semi-parametric approach to heterogeneous dynamic panel data modelling. The method generalizes existing approaches to model cross-section homogeneity within such panels. It allows for partial influence of other cross-section units on estimated coefficients, differentiating between short- run and long-run homogeneity, and determines the optimal degree of such homogeneity. The issue of cross-section homogeneity emerges as a special case of categorical conditioning. Applying our model to equilibrium exchange rate determination in a cross-country panel, we find evidence of largely heterogeneous adjustment and more homogeneous long-run coefficients across countries. The coefficient heterogeneity appears largely idiosyncratic and is not captured by simple categorizations like exchange rate regime classification.

description: Through an intertemporal budget constraint, jurisdictions may gain advantages in tax and spending competition by 'competing' on debt. While the existing spatial econometric literature focuses on tax and spending competition, very little is known about spatial interaction via public debt. This paper estimates the spatial interdependence of public debt among German municipalities using a panel on municipalities in the two largest German states from 1999 to 2006. We find significant and robust interaction effects between debt of neighboring municipalities, which we compare to spatial tax and spending interactions. The results indicate that a municipality increases its per capita debt by 16-33 Euro as a reaction to an increase of 100 Euro in neighboring municipalities.

title: Trajectories of Functional and Species Change During Plant Community Assembly in a California Serpentine Grassland
Creators: name: Habenicht, Melissa N
Publisher: name: Western Washington University
Year: 2015

description: "
Elucidating the mechanisms that underlie species coexistence and community assembly is central for understanding basic ecological patterns of species’ abundances, how global change may alter those patterns, and how to effectively manage ecosystems. Niche and neutral theory represent two opposite sides on a continuum of potential drivers of community composition and coexistence. Niche theory poses that species’ differences facilitate coexistence by causing intraspecific competition to be stronger than interspecific competition. In contrast, neutral theory assumes that species are similar in fitness and their effects on one another, and that stochastic variation in births, deaths, immigration, and extinction allow coexistence. Rather than being mutually exclusive mechanisms, niche and neutral processes may operate at different levels of biological organization. We tracked the natural assembly of experimental serpentine grassland communities to test this idea. Specifically, we hypothesized: 1) complementarity, a niche-based deterministic process, would cause communities to converge toward a common functional composition; while 2) species composition within functional groups would be neutral and driven by stochastic forces such as dispersal.

The communities were created in 1992 for a previous experiment and initially varied in both functional (and therefore species) richness and composition. Four functional groups, chosen based on complementary resource acquisition strategies, comprised the experimental communities: early season annuals, late season annuals, perennial bunch grasses, and nitrogen-fixing annuals. Starting in 2001, species from the surrounding grassland colonized the experimental communities. I analyzed data on species richness and relative abundance over the subsequent six years. Over the first four years of the study, both functional and species compositions converged across treatments. Subsequently, however, functional composition remained relatively constant while species composition diverged among communities. Niche complementarity likely drove overall convergence in functional composition and initial convergence in species composition. However, species composition was driven by additional forces, including trait-environment relationships, density-dependent plant feedbacks, and potential neutrality. Our results suggest that community composition may be driven simultaneously by both niche and neutral processes, and that the drivers of community composition likely shift over time.

description: Recent studies indicate that the natural resource curse, that is, the negative link between resource abundance and growth, may operate through a country’s financial system. Scholars show that resource-abundant economies suffer from lower financial development, which may indirectly affect welfare. The present study provides an explanation for this financial channel. It argues that resource-rich countries are likely to have a concentrated export structure, causing a reduction of the financial system’s size due to volatility and the associated high real interest rates. The paper shows empirically that export concentration tends to weaken private credit to GDP. The analysis builds on cross-sectional and panel data from 93 countries for the period 1970-2007. The direction of causality is tested with an instrumentation strategy using geographic and geospatial variables as well as dynamic panel techniques.

description: We analyze empirically the optimal design of social insurance and assistance programs when families obtain insurance by making labor supply choices for both spouses. For this purpose, we specify a structural life-cycle model of the labor supply and savings decisions of singles and married couples. Partial insurance against wage and employment shocks is provided by social programs, savings and the labor supplies of all adult household members. The optimal policy mix focuses mainly on Social Assistance, which provides a permanent universal household income oor, with a minor role for temporary earnings- related Unemployment Insurance. Reecting that married couples obtain intra- household insurance by making labor supply choices for both spouses, the optimal generosity of Social Assistance decreases in the proportion of married individuals in the population. The link between optimal program design and the family context is strongest in low-educated populations.

description: We investigate the dependence of switching current density on the junction sizes in the spin transfer torque nanopillar structures by using micromagnetic simulations. While the macro spin model predicts weak dependence of switching current density on the junction sizes, we find that the switching current density is a sensitive function of the junction sizes. It can be explained with the complicated spin configurations and dynamics during the switching process. The detail spin configurations and dynamics are determined by spin wave excitation with the finite wave vector, which is related with the exchange coupling energy and junction shape.

description: By using estimates from an Almost Ideal Demand System (AIDS), we investigate how the German energy tax on car fuels changes the private households’ CO2 emissions, living standards, and post-tax income distribution. Our results show that the tax implies a trade-off between the aim to reduce emissions and vertical equity, which refers to the idea that people with a greater ability to pay taxes should pay more.

description: Generous income support programs as provided by European welfare states have often been blamed to hamper employment. This paper investigates the importance of incentives inherent in the tax-benefit system for the individual decision to take up work. Using German microdata over the period 1993- 2010 we find that recent reforms in Germany increased work incentives at the extensive margin measured by the Participation Tax Rate (PTR), particularly for low- income individuals. Work incentives are even higher if the time horizon is extended to more than one year, pointing at an overestimation of the disincentives by standard measures. Regression analysis reveals that a decrease in the PTR increases the likelihood of taking up work significantly.

description: Melanin protects Z. tritici against SDHI fungicides. Reduction in growth by fungicides (% growth decrease) of the wild-type 3D7 and 3D7Δzmr1. Strains were grown on Whatman filter paper placed on PDA for 5 days and later transferred to PDA plates supplemented with the fungicide bixafen or propiconazole. Asterisks (*) indicate that the percentage in decrease in growth of the mutant strain, in the presence of the fungicide, is significantly different from the wild-type 3D7 (Kruskal-Wallis, p value ≤ 0.05). Mean and standard error of differential radial size of at least 25 colonies grown on three independent plates are presented. The experiment was performed twice with similar results. (PDF 122 kb)

description: We derive rigorously the reduced dynamical laws for quantized vortex dynamics of the nonlinear wave equation on the torus when the core size of vortex $\varepsilon\to 0$. It is proved that the reduced dynamical laws are second-order nonlinear ordinary differential equations which are driven by the renormalized energy on the torus, and the initial data of the reduced dynamical laws are determined by the positions of vortices and the momentum. We will also investigate the effect of the momentum on the vortex dynamics.

title: Marine Microzooplankton are Indirectly Affected by Ocean Acidification Through Direct Effects on Their Phytoplankton Prey
Creators: name: Kendall, Kasey
Publisher: name: Western Washington University

description:
To date few studies have explored indirect effects of OA on microzooplankton. Microzooplankton grazing behavior is acutely sensitive to prey cell size, physiology, and nutritional state, which may all be influenced by OA in phytoplankton. Therefore, microzooplankton may be indirectly affected by OA through their prey. Due to undersaturation of CO2 for the carboxylating enzyme, RuBisCO, increasing availability of CO2 through acidification could affect algal cellular processes, physiological states, and the nutritional value for their primary consumers. In this study I tested for indirect effects of OA on three microzooplankton species, representing two ecologically significant functional groups of microzooplankton, tintinnid ciliates (Favella taraikaensis and Eutintinnus sp.) and heterotrophic dinoflagellates (Oxyrrhis marina). I characterized the direct effects of OA on the physiology and biochemistry of two phytoplankton, Emiliania huxleyi CCMP 2668 and Rhodomonas sp. CCMP 755 under three pCO2 treatments (400ppmv, 750ppmv, and 1000ppmv). I quantitatively assessed cell size, C:N, growth rate, photosynthetic capacity, cellular carbohydrate and chlorophyll a concentrations. Phytoplankton cell size increased significantly under 750 ppmv and 1000 ppmv with no other consistent changes under elevated pCO2. To test for indirect effects on microzooplankton, the grazers were fed a diet of pCO2-acclimated cells. All three microzooplankton species showed increased short-term ingestion rates and increased population feeding on prey grown in elevated pCO2. Multiple Linear Regression models revealed that that OA indirectly affects microzooplankton through direct effects on the size of their phytoplankton prey. This pathway for OA effects has the potential for widespread impacts within marine food webs.

Physics potential of neutrino oscillation experiment with a far detector in Oki Island along the T2K baseline

description: Oki Island is located between Japan and Korea along the Tokai-To-Kamioka (T2K) baseline. The distance from J-PARC to Oki Island is about 653km, which is twice that of the T2K experiment (L=295km). When the off-axis angle of the neutrino beam from J-PARC is 3.0^\circ (2.0^\circ) at Super-Kamiokande (SK), the off-axis beam (OAB) with 1.4^\circ (0.6^\circ) reaches at Oki Island. We examine physics case of placing a far detector in Oki Island during the T2K experimental period. We estimate the matter density profile along the Tokai-to-Oki baseline by using recent seismological measurements. For a detector of 100kton fiducial volume and 2.5x10^21 POT (protons on target) exposure for both ν_μand \barν_μbeams, we find that the mass hierarchy pattern can be distinguished at 3σlevel if sin^22theta_rct \equiv 4|U_{e3}|^2(1-|U_{e3}|^2) \gsim 0.09, by observing the electron-like CCQE (Charged-Current Quasi Elastic) events. The CP phase in the Maki-Nakagawa-Sakata lepton flavor mixing matrix, δ_mns, can be constrained with \pm 20^\circ. As a reference, we repeat the same analysis by placing the same detector in Korea at L=1000km and OAB=0.5^\circ (T2KK) and also by placing it at the SK site (T2K_122). The Tokai-to-Kamioka-OKI (T2KO) sensitivity to the mass hierarchy is about 1/3 (in Δχ^2_min) of T2KK, while the sensitivity to the phase δ_mns is similar between T2KO and T2KK. The T2K_122 option has almost no sensitivity to the mass hierarchy, and cannot measure the CP phase except when δ_mns \sim -90^\circ (90^\circ) for the normal (inverted) hierarchy.

title: Effect of Substrate Stiffness and Formin on Fibrillar Force Generation by Fibroblasts
Creators: name: Eftekharjoo, Mohamad

Publisher: name: Old Dominion University Libraries

description: Fibroblasts in connective tissues often interact with a fibrillar extra-cellular matrix (ECM) that restricts their shape along one-dimension (1D, along the fiber). At the same time, the fibroblast responds to and affects the mechanical nature of its microenvironment which consists of the inter-woven fibrillary ECM, other matrix components and cells. The determinants of force generation by fibroblasts, which is necessary to understand normal physiology and disease, is however unclear. In order to construct the 1D geometry of fibroblasts, we plated NIH 3T3 fibroblasts on micropatterned 1.5 μm-wide fibronectin lines on polyacrylamide gels with stiffness of 13 or 45 kPa. We used traction force microscopy to quantify the cellular traction force exerted and the associated strain energy stored in the substrate. We found that strain energy or maximum traction stress is not a function of cell length. Even though cell length depends on substrate stiffness, the strain energy and the maximum traction forces exerted were independent of substrate stiffness. Besides, we found that fibroblasts in a 1D morphology have prominent linear actin structures and inhibition of a family of actin nucleators (formin) significantly reduced linear actin level. Importantly, we found that the fibrillar force exerted by fibroblasts also strongly decreased, implicating formin in fibrillar fibroblast force exertion.

description: We consider the problem of estimating a random state vector when there is information about the maximum distances between its subvectors. The estimation problem is posed in a Bayesian framework in which the minimum mean square error (MMSE) estimate of the state is given by the conditional mean. Since finding the conditional mean requires multidimensional integration, an approximate MMSE estimator is proposed. The performance of the proposed estimator is evaluated in a positioning problem. Finally, the application of the estimator in inequality constrained recursive filtering is illustrated by applying the estimator to a dead-reckoning problem. The MSE of the estimator is compared with two related posterior Cramér-Rao bounds.
