description: The discovery of gravitational waves (GWs) provides an unprecedented arena to test general relativity, including the gravitational Lorentz invariance violation (gLIV). In the propagation of GWs, a generic gLIV leads to anisotropy, dispersion, and birefringence. GW events constrain the anisotropic birefringence particularly well. Kostelecký and Mewes (2016) performed a preliminary analysis for GW150914. We improve their method and extend the analysis systematically to the whole GW transient catalog, GWTC-1. This is the first global analysis of the spacetime anisotropic Lorentzian structure with a catalog of GWs, where multiple events are crucial in breaking the degeneracy among gLIV parameters. With the absence of abnormal propagation, we obtain new limits on 34 coefficients for gLIV in the nonminimal gravity that surpass previous limits by $\sim 10^2$-$10^5$.

Stochastic Acceleration of 3He and 4He by Parallel Propagating Plasma Waves

description: Stochastic acceleration of $^3$He and $^4$He from a thermal background by parallel propagating turbulent plasma waves with a single power-law spectrum of the wavenumber is studied. In the model, both ions interact with several resonant modes. When one of these modes dominates, the acceleration rate is reduced considerably. At low energies, this happens for $^4$He, but not for $^3$He where contributions from the two stronger modes are comparable so that acceleration of $^3$He is very efficient. As a result, the acceleration of $^4$He is suppressed by a barrier below $\sim 100$ keV nucleon$^{-1}$ and there is a prominent quasi-thermal component in the $^4$He spectra, while almost all the injected $^3$He ions are accelerated to high energies. This accounts for the large enrichment of $^3$He at high energies observed in impulsive solar energetic particle events. With reasonable plasma parameters this also provides a good fit to the spectra of both ions. Beyond $\sim 1$ MeV nucleon$^{-1}$, the spectrum of $^3$He is softer than that of $^4$He, which is consistent with the observed decrease of the $^3$He to $^4$He ratio with energy. This study also indicates that the acceleration, Coulomb losses and diffusive escape of the particles from the acceleration site {\it all} play important roles in shaping the ion spectra. This can explain the varied spectral shapes observed recently by the {\it Advanced Composition Explorer}.

Measuring cost and efficiency in United States crude oil resource development, 1977--1990: A frontier translog cost function approach
Creators: name: Fagan, Marie Nobile
Publisher: name: ProQuest
Year: 2023
Subjects: classificationCode: 38
subject: Economics

description: The U.S oil industry provides an exceptional example of adjustment to a dramatic and disastrous price collapse. After a decade of high (or rising) oil prices, the oil price collapse of 1986 forced oil companies to reduce the cost of developing reserves. This research isolates the individual effects of input price reductions, resource depletion, and technical and firm-specific strategic changes over time on the major U.S. oil companies' cost of finding crude oil in the United States over the period 1977-1990. The model used in this study is a translog specification of the cost-minimization model of firm behavior, combined with econometric techniques for estimating a frontier cost function. The estimates of the marginal cost of crude oil resource development provided by this research can aid others in the debate over the Hotelling Valuation Principle, and shed light on the competitiveness of U.S. crude oil reserves in the world oil market. This research concludes that resource depletion had a significant cost-increasing effect on onshore operations, while showing no statistically significant effect on relatively newer offshore operations. Of particular interest are the estimates of the marginal cost of crude oil resource development, which indicate scale economies for both onshore and offshore operations. Efficiency tests indicated the major U.S. oil companies did not exhibit technical inefficiency relative to the frontier cost function in any given year, although there were systematic differences in the ability to improve efficiency over the 1977-1990 period.

description: We investigate a heat engine under an adiabatic (Thouless) pumping process. In this process, the extracted work and lower bound on dissipated availability are characterized by a vector potential and a Riemannian metric tensor, respectively. We derive a trade-off relation between the power and effective efficiency.

Non-perturbative RR Potentials in the c=1 Matrix Model
Creators: name: Gross, David J.
name: Walcher, Johannes
Publisher: name: arXiv
Year: 2003
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We use the \hat c=1 matrix model to compute the potential energy V(C) for (the zero mode of) the RR scalar in two-dimensional type 0B string theory. The potential is induced by turning on a background RR flux, which in the matrix model corresponds to unequal Fermi levels for the two types of fermions. Perturbatively, this leads to a linear runaway potential, but non-perturbative effects stabilize the potential, and we find the exact expression V(C)=\frac{1}{2π}\int da\arccos [\cos(C)/\sqrt{1+e^{-2πa}}]. We also compute the finite-temperature partition function of the 0B theory in the presence of flux. The perturbative expansion is T-dual to the analogous result in type 0A theory, but non-perturbative effects (which depend on C) do not respect naive R\to 1/R duality. The model can also be used to study scattering amplitudes in background RR fluxes.

description: Prior work in computational bioacoustics has mostly focused on the detection of animal presence in a particular habitat. However, animal sounds contain much richer information than mere presence; among others, they encapsulate the interactions of those animals with other members of their species. Studying these interactions is almost impossible in a naturalistic setting, as the ground truth is often lacking. The use of animals in captivity instead offers a viable alternative pathway. However, most prior works follow a traditional, statistics-based approach to analysing interactions. In the present work, we go beyond this standard framework by attempting to predict the underlying context in interactions between captive \emph{Rousettus Aegyptiacus} using deep neural networks. We reach an unweighted average recall of over 30\% -- more than thrice the chance level -- and show error patterns that differ from our statistical analysis. This work thus represents an important step towards the automatic analysis of states in animals from sound.

description: The random Lorentz gas (RLG) is a minimal model of transport in heterogeneous media. It also models the dynamics of a tracer in a glassy system. These two perspectives, however, are fundamentally inconsistent. Arrest in the former is related to percolation, and hence continuous, while glass-like arrest is discontinuous. In order to clarify the interplay between percolation and glassiness in the RLG, we consider its exact solution in the infinite-dimensional $d\rightarrow\infty$ limit, as well as numerics in $d=2\ldots 20$. We find that the mean field solutions of the RLG and glasses fall in the same universality class, and that instantonic corrections related to rare cage escapes destroy the glass transition in finite dimensions. This advance suggests that the RLG can be used as a toy model to develop a first-principle description of hopping in structural glasses.

description: What shaped the emergence of sociological research during the period of late socialism in Albania? What are the causal mechanisms through which a liberalised cultural policy brought about the change. The traditional role of the socialist intelligentsia lessened in importance while the role of social scientists emerged. In the very final years of the state socialist regime, in 1989 to 1990, the latter were pitted against Party cadres and representatives in defending a limited yet free academic practice. In order to explain the intricate, early process of the emergence of sociology under state socialism in Albania, this article utilises a layered theoretical framework that tries to capture the interaction between stages of regime development, the coexistence of various competing modes of legitimation, and the transformation of the heteronomous sector of cultural production into an emergent field of cultural production.

description: The photoproduction of eta-mesons from 2H and 4He has been studied for energies close to the production thresholds. The experiments were carried out with the tagged photon beam of the Mainz MAMI accelerator. The eta-mesons were detected via their two photon decays with the electromagnetic calorimeter TAPS. Total cross sections, angular and momentum distributions of the eta-mesons have been determined for both reactions. The total cross sections in the threshold region show a large enhancement over the predictions of a participant - spectator model, indicating significant final state interaction effects. The results are compared to recent model calculations taking into account nucleon-nucleon and nucleon-eta final state interaction effects on different levels of sophistication.

The effects of student self-assessment on students' attitudes and academic performance in a college mathematics course
Creators: name: Tascione, Carol Ann
Publisher: name: American University
Year: 2023

description: The professional literature in mathematics education is filled with recommendations for changing the way mathematics is taught and how student performance is evaluated. Appeals to reform curriculum, instruction and evaluation are gaining acceptance. Unfortunately, there is little experimental evidence that supports the efficacy of these suggested reform measures. This research was designed to determine if student self-assessment, a form of alternative assessment, can enhance student academic performance and improve student attitudes in the mathematics classroom. The study involved four Finite Mathematics classes at The American University; two classes made up the experimental group, the other two comprised the control group. The experiment was designed so that instructional and evaluation procedures were the same for all students participating in the study. Student self-assessment supplemented other evaluation procedures for the experimental group: students in the experimental group assessed their own performance on a variety of tasks throughout the semester. Test grades and attitude surveys were used to determine if student self-assessment had a measurable impact on the experimental group's performance. Qualitative evidence was also collected during the course of the study. Conclusions were based on both statistical and qualitative evidence. One-way analysis of variance, the Mann-Whitney U test, and the t-test for paired samples were used to statistically test the study hypotheses. Statistical evidence indicates that end-of-study attitudes of experimental students towards mathematics assessment were significantly more positive than their pre-study attitudes. Statistical evidence also indicates that there was a significant difference in the academic performance of male and female experimental students at the end of the experimental treatment. Males scores on the final exam were significantly better than those of females when pre-study scores were taken into consideration. There were no other statistically significant findings that can be attributed to the experimental treatment. However, qualitative evidence and statistical testing of selected subgroups of the study population point out the benefits of the experimental intervention.

description: This study examines archaeological data from the Hughes site in the context of historical processes evident in the regional archaeological record. The study focuses on the Hughes village as a particular form of Late Woodland residential community that was historically linked to social and economic practices that are first documented in the region nearly four thousand years ago during the Transitional period. The historical context of the Hughes site is established in the first part of this study through the review and interpretation of archaeological data from various sites within the Potomac Piedmont and within the larger Potomac Valley and Middle Atlantic region. These data are examined from multiple perspectives, including the history of resource use and occupation of the Piedmont relative to surrounding areas, the histories of selected social and economic practices involved in long-term processes of culture change, and the history of the cultural group with whom the residents of the Hughes site were most closely related. The remainder of the study focuses explicitly on the Hughes village site, beginning with a review of the archaeological data recovered during previous and more recent excavations and concluding with an examination of the cultural landscape of the region during the site's occupation and the social construction of the Hughes village community. Data related to site structure, village economy, and stylistic expression at the site suggest that the residents of the site were adaptive, economically self-sufficient, egalitarian in terms of access to resources, socially undifferentiated, and that they represented themselves as a unified social entity. The burial data from the site, on the other hand, suggest that the village was composed of multiple subgroups that likely maintained a degree of social distance, had different conceptions of the role of the individual in communal life, and possibly had differential access to external relationships. This internal tension, together with external tension rising from their occupation of a strategic location on the Potomac River ca. 1400 A.D., may have precipitated the abandonment of the site and probable move to a location in the Shenandoah Valley.

description: In this study, a stochastic model was applied to investigate the degradation of landfill leachate by solar photo-Fenton processes. The coefficient of determination (R2) between experimental and predicted data ranged from 0.9958 to 0.9995. The optimal conditions for the initial phase (lasting 5–22 min) were high Fe2+ level, low pH level, and intermediate H2O2 level. For the second phase, optimal leachate degradation percentages were obtained by maintaining the pH, increasing H2O2, and decreasing Fe2+ to the lowest level. Determination of optimal reaction conditions (such as pH, Fe2+, and H2O2 values) for both degradation phases is of paramount importance for process scale-up. The major contribution of this study was the development of a tool that considers the effects of one or more reactions on organic carbon degradation. This was achieved by assessing the significance of the effects of experimental conditions on model parameters for the fast and slow steps of leachate degradation by advanced oxidation processes.

description: The excess of cosmic positrons observed by the HEAT experiment may be the result of Kaluza-Klein dark matter annihilating in the galactic halo. Kaluza-Klein dark matter annihilates dominantly into charged leptons that yield a large number and hard spectrum of positrons per annihilation. Given a Kaluza-Klein dark matter particle with a mass in the range of 300-400 GeV, no exceptional substructure or clumping is needed in the local distribution of dark matter to generate a positron flux that explains the HEAT observations. This is in contrast to supersymmetric dark matter that requires unnaturally large amounts of dark substructure to produce the observed positron excess. Future astrophysical and collider tests are outlined that will confirm or rule out this explanation of the HEAT data.

description: We extend the regret analysis of the online distributed weighted dual averaging (DWDA) algorithm [1] to the dynamic setting and provide the tightest dynamic regret bound known to date with respect to the time horizon for a distributed online convex optimization (OCO) algorithm. Our bound is linear in the cumulative difference between consecutive optima and does not depend explicitly on the time horizon. We use dynamic-online DWDA (D-ODWDA) and formulate a performance-guaranteed distributed online demand response approach for heating, ventilation, and air-conditioning (HVAC) systems of commercial buildings. We show the performance of our approach for fast timescale demand response in numerical simulations and obtain demand response decisions that closely reproduce the centralized optimal ones.

These SEDs are then used to predict at various redshifts the number of Seyfert type 1 and type 2, starburst, normal galaxies, and quasars, that will be detected by future Space Missions dedicated to far-infrared and submillimeter astronomy, like SIRTF and Herschel. These predictions are then compared with the expected capabilities and detection limits of future deep far-IR surveys. Possible ways to identify AGN candidates on far-IR colour-colour plots for follow-up observations are then explored.

description: Coronavirus Disease 2019 (COVID-19), caused by the novel coronavirus (SARS-CoV-2), has led to a large number of patients having to be admitted to intensive care because of respiratory failure and multi-organ dysfunction. About 20% of critically ill patients with COVID-19 require renal replacement therapy (RRT). However, data on the prediction of acute kidney injury requiring RRT is lacking. Novel biomarkers, such as mid-regional pro-adrenomedullin (MR-proADM) might be likely candidates for risk assessment due to its involvement during the initial phase of multiple organ dysfunction. Therefore, the aim of this study was to investigate MR-proADM for prediction of RRT in critically ill patients with COVID-19. We analysed data of all consecutive patients with microbiologically confirmed COVID-19, requiring ICU admission at one of 12 intensive care units at a tertiary care university hospital in Germany between March and September 2020. Clinical characteristics including details on acute kidney injury, RRT, and survival were assessed. MR-proADM was measured as part of routine lab monitoring on admission to ICU. 64 patients were included in the study. The median age was 62.5 (54 – 73) years; 49 patients (77%) were male. 47 (73%) patients were mechanically ventilated and 50 (78%) needed vasopressor therapy. 25 (39%) patients suffered from severe ARDS; veno-venous extracorporeal membrane oxygenation was established in 10 patients. 29 (45%) patients required RRT during the ICU-stay; Median time from ICU admission to start of RRT was 2 (1 – 9) days. MR-proADM on ICU admission was significantly higher in patients requiring RRT (2.491 vs. 1.230 nmol/l; p = 0.002) and showed the highest correlation with SOFA renal subscore on day 1. ROC curve analysis showed that MR-proADM predicts RRT with an AUC of 0.685 (95% CI: 0.543 – 0.828; p = 0.019). In multivariable logistic regression MR-proADM was an independent predictor (OR: 3.813, 95% CI 1.110 – 13.102, p < 0.05) for the requirement of RRT. Acute kidney injury requiring RRT is a frequent finding in critically ill patients with COVID-19. MR-proADM on admission to ICU was able to predict later requirement for RRT, which may be of interest for early risk stratification and patient management.

description: We study the processes $K\bar{K} \to ϕ$, $πD \to D^\ast$, $π\bar{D} \to \bar{D}^\ast$, and the production of $ψ(3770)$, $ψ(4040)$, $ψ(4160)$, and $ψ(4415)$ mesons in collisions of charmed mesons or charmed strange mesons. The process of 2-to-1 meson-meson scattering involves a quark and an antiquark from the two initial mesons annihilating into a gluon and subsequently the gluon being absorbed by the spectator quark or antiquark. Transition amplitudes for the scattering process derive from the transition potential in conjunction with mesonic quark-antiquark wave functions and the relative-motion wave function of the two initial mesons. We derive these transition amplitudes in the partial wave expansion of the relative-motion wave function of the two initial mesons so that parity and total-angular-momentum conservation are maintained. We calculate flavor and spin matrix elements in accordance with the transition potential and unpolarized cross sections for the reactions using the transition amplitudes. Cross sections for the production of $ψ(4040)$, $ψ(4160)$, and $ψ(4415)$ relate to nodes in their radial wave functions. We suggest the production of $ψ(4040)$, $ψ(4160)$, and $ψ(4415)$ as probes of hadronic matter that results from the quark-gluon plasma created in ultrarelativistic heavy-ion collisions.

The impact of structural hypocrisy on the school performance of young African-American males
Creators: name: Towns, Donna Penn

description: This study of life in an inner-city elementary school takes a critical look at cultural factors in the school that negatively affect the school performance of young African American male students. If, as a review of the literature indicated, the performance of young black males begins to decline by grade four, the question posed was, what is it in these early years that effects the decline?; The ethnography is the result of a year spent as a participant/observer in an elementary school in Washington, D.C. The observation of classroom sessions, PTA meetings, assemblies, cafeteria and playground activities; the interviewing of both children and adult personnel in the school, and the examination of documentary evidence of student performance rendered an in-depth picture of the plurality of cultures that interplay as the participants attempt to derive meaning from their disparate experiences. It pinpoints aspects of the school culture transmitted by the teachers and administrators, which make the school culture unique, on the one hand, while reflecting the norms and values of the dominant, white middle-class culture of American society in general, on the other. It demonstrates ways in which this culture conflicts with the culture that underpriviledged, African American children from the inner-city bring to their school experience. Highlighted in the study are the disparities between words and actions--between ideology and reality--found not only in this particular school, but in American society in general in its beliefs about schools and the role of education. The suggestion is that the conflict between ideology and reality creates a need to mask reality. This mask is referred to as hypocrisy--a kind of hypocrisy that is so pervasive and deeply entrenched in the system that those who participate in it are not always aware of its existence. In other words, it is a "structural hypocrisy.". The conclusion is that the difference in socialization patterns of poor, black males predisposes them to reject the hypocrisy as they move up in grade level. This rejection results in passive or active resistance, both of which lead to their ultimate failure in the school system.

description: We present galaxy-galaxy lensing measurements over scales 0.025 to 10 Mpc/h in the Sloan Digital Sky Survey. Using a flux-limited sample of 127,001 lens galaxies with spectroscopic redshifts and mean luminosity = L_* and 9,020,388 source galaxies with photometric redshifts, we invert the lensing signal to obtain the galaxy-mass correlation function xi_{gm}. We find xi_{gm} is consistent with a power-law, xi_{gm} = (r/r_0)^{-gamma}, with best-fit parameters gamma = 1.79 +/- 0.06 and r_0 = (5.4+/-0.7)(0.27/Omega_m)^{1/gamma} Mpc/h. At fixed separation, the ratio xi_{gg}/xi_{gm} = b/r where b is the bias and r is the correlation coefficient. Comparing to the galaxy auto-correlation function for a similarly selected sample of SDSS galaxies, we find that b/r is approximately scale independent over scales 0.2-6.7 Mpc/h, with mean  = (1.3+/-0.2)(Omega_m/0.27). We also find no scale dependence in b/r for a volume limited sample of luminous galaxies (-23.0 < M_r < -21.5). The mean b/r for this sample is _{Vlim} = (2.0+/-0.7)(Omega_m/0.27). We split the lens galaxy sample into subsets based on luminosity, color, spectral type, and velocity dispersion, and see clear trends of the lensing signal with each of these parameters. The amplitude and logarithmic slope of xi_{gm} increases with galaxy luminosity. For high luminosities (L ~5 L_*), xi_{gm} deviates significantly from a power law. These trends with luminosity also appear in the subsample of red galaxies, which are more strongly clustered than blue galaxies.

description: Prime power fold cyclic branched covers along smoothly slice knots all bound rational homology balls. This phenomenon, however, does not characterize slice knots. In this paper, we give a new construction of non-slice knots that have the above property. The sliceness obstruction comes from computing twisted Alexander polynomials, and we introduce new techniques to simplify their calculation.
