description: The American Indian population is in a period of transition. It is young, growing, and becoming more urban. There were some improvements in income, housing, education, and health in the 1960-70 decade, but Indians remain the most disadvantaged of the minority ethnic groups in the United States. By most of the above measures, Indians, especially rural Indians, are not as well off as the U.S. population as a whole. But the Indian people are moving toward self-determination, or self-government, in programs to enhance their lives.

Compact planetary systems perturbed by an inclined companion: II. Stellar spin-orbit evolution

description: The stellar spin orientation relative to the orbital planes of multiplanet systems are becoming accessible to observations. Here, we analyze and classify different types of spin-orbit evolution in compact multiplanet systems perturbed by an inclined outer companion. Our study is based on classical secular theory, using a vectorial approach developed in a separate paper. When planet-planet perturbations are truncated at the second order in eccentricity and mutual inclination, and the planet-companion perturbations are developed at the quadrupole order, the problem becomes integrable. The motion is composed of a uniform precession of the whole system around the total angular momentum, and in the rotating frame, the evolution is periodic. Here, we focus on the relative motion associated to the oscillations of the inclination between the planet system and the outer orbit, and of the obliquities of the star with respect to the two orbital planes. The solution is obtained using a powerful geometric method. With this technique, we identify four different regimes characterized by the nutation amplitude of the stellar spin-axis relative to the orbital plane of the planets. In particular, the obliquity of the star reaches its maximum when the system is in the Cassini regime where planets have more angular momentum than the star, and where the precession rate of the star is similar to that of the planets induced by the companion. In that case, spin-orbit oscillations exceed twice the inclination between the planets and the companion. Even if mutual inclination is only ~ 20 deg, this resonant case can cause the spin-orbit angle to oscillate between perfectly aligned and retrograde values.

description: Heavy metal contamination in various water resources is of great concern because of the toxic effect on human beings and other animals and plants in the environment. Lead is a major element which is released to the environment including water bodies by many industries and it is well known that the presence of Pb(II) in water, even at very low concentrations, is extremely harmful to the human. Therefore, the aim of the present study was to investigate the Pb adsorption potential of chitosan coated activated carbon derived from rice husk (CCAC) in aqueous media. First, chitin was extracted from shrimp shell wastes by following a standard procedure and it was deacetylated to obtain chitosan (deacetylation percentage = 82%). In the preparation of activated carbon from rice husk, HCl acid (5 % v/v) was used as the activating agent. The adsorbent of the study, CCAC was then prepared by coating activated carbon derived from rice husk (20.00 g) with chitosan (3.00 g dissolved in 1% v/v acetic acid) to improve the stability and mechanical strength of chitosan. The surface morphology and the elemental composition of CCAC was examined by Scanning Electron Microscopy & Energy Dispersive Spectroscopy (SEM/EDAX). The novel adsorbent was further characterized by Fourier Transform Infrared Spectroscopy (FT-IR). In order to determine the Pb adsorption potential of CCAC, batch adsorption studies were conducted at room temperature at pH 7. The effects of various experimental parameters such as initial Pb (II) concentration, dose of adsorbent and shaking time on Pb adsorption to CCAC were evaluated. According to the results, the maximum lead removal percentage (89%) was observed at initial Pb (II) concentration of 2 ppm, adsorbent dosage of 1 g/L and 120 minutes of shaking time. Further, the equilibrium adsorption data were analyzed by the Langmuir isotherm model and the Freundlich isotherm model for Pb adsorption onto CCAC. Among the two models, Langmuir isotherm best fitted with the equilibrium data (R2= 0.9916) with a maximum adsorption capacity (q0) of 24.39 mg/g. Based on the results, it can be concluded that CCAC can be considered as an efficient and cost-effective adsorbent for the removal of heavy metals such as Pb from industrial wastewater.

While these Majorana fermions are not topologically protected, the highly tunable setup provides a realistic system for observing the exotic physics associated with Majorana fermions as well as their dynamical generation and manipulation.

description: This paper proposes a multiple-membership generalized linear mixed model for ranking college football teams using only their win/loss records. The model results in an intractable, high-dimensional integral due to the random effects structure and nonlinear link function. We use recent data sets to explore the effect of the choice of integral approximation and other modeling assumptions on the rankings. Varying the modeling assumptions sometimes leads to changes in the team rankings that could affect bowl assignments.

Maximum approximate entropy and r threshold: A new approach for regularity changes detection

description: Approximate entropy (ApEn) has been widely used as an estimator of regularity in many scientific fields. It has proved to be a useful tool because of its ability to distinguish different system's dynamics when there is only available short-length noisy data. Incorrect parameter selection (embedding dimension $m$, threshold $r$ and data length $N$) and the presence of noise in the signal can undermine the ApEn discrimination capacity. In this work we show that $r_{max}$ ($ApEn(m,r_{max},N)=ApEn_{max}$) can also be used as a feature to discern between dynamics. Moreover, the combined use of $ApEn_{max}$ and $r_{max}$ allows a better discrimination capacity to be accomplished, even in the presence of noise. We conducted our studies using real physiological time series and simulated signals corresponding to both low- and high-dimensional systems. When $ApEn_{max}$ is incapable of discerning between different dynamics because of the noise presence, our results suggest that $r_{max}$ provides additional information that can be useful for classification purposes. Based on cross-validation tests, we conclude that, for short length noisy signals, the joint use of $ApEn_{max}$ and $r_{max}$ can significantly decrease the misclassification rate of a linear classifier in comparison with their isolated use.
title: Application of ultrasound technology for improving diagnostic capability in placental dysfunction

description: Introduction: Hypertensive disorders of pregnancy (HDP) and fetal growth restriction (FGR) represent two of the main pregnancy complications and are associated with an increased risk for the mother and her child to develop long term health complications. There is not yet a complete understanding of the physiopathology of these disorders. Historically, the placenta was the major focus of research to understand HDP and FGR. However, there is now a growing body of evidence supporting the significant contribution of the maternal cardiovascular system in the origins of these diseases. In this regard,maternal and fetal ultrasound and non-invasive devices have become important tools in the study of maternal hemodynamics and fetal growth.

Objective and hypothesis: The overall objective of this research is to characterise and evaluate the feasibility of a combination of Ophthalmic artery Doppler and maternal cardiovascular system assessment for the study of HDP and FGR, and in consequence, improve diagnostic capability of these pathologies. I hypothesise that they will provide a useful tool for diagnosis and characterization of HDP and FGR.

Methods: A prospective observational cohort study was conducted in a tertiary hospital between December 2020 to December 2021.Ophthalmic and uterine artery Doppler along with maternal hemodynamics and pulse wave analysis were assessed in 168 women with singleton pregnancies at 28 to 40 weeks gestation. Analysis of 10 maternal plasma biomarkers was also performed in 61 patients. The total cohort was sub-divided into women with hypertension and/or delivering a small baby and compared to nonhypertensive and non-growth restricted controls.

Results: Complicated pregnancies (HDP/FGR) had an increase in systemic vascular resistance and worse hemodynamic profile when compared with controls. Only one Ophthalmic artery Doppler parameter (peak systolic velocity ratio, PSVR) was significantly higher in both hypertensive group and in normotensive individuals with a small for gestational age neonate.

Although the Doppler study of the Ophthalmic artery was well accepted by the patients and a fast and easy method, maternal cardiovascular assessment with non-invasive devices presented technical difficulties that caused the exclusion of nearly one third of the cohort.

Biomarkers of placental dysfunction were significantly different between the study groups, however no correlation was found between maternal blood levels of biomarkers and Ophthalmic artery Doppler measurements.

Discussion: Ophthalmic artery Doppler assessment could be a useful tool to use in daily clinical practice to improve diagnostic capability of hypertensive disorders or fetal growth restriction during pregnancy.

description: Feasibility of oxidative cleavage of methyl oleate in a homogeneous reaction, facilitating the subsequent recovery of the catalyst from a single phase, is a challenge. Using the high molecular catalyst phosphotungstic acid (2880 Da) as an affordable catalyst offers potential for membrane separation. To gain insight into side-reactions, the intermediate methyl 9,10-dihydroxystearate was first applied as a model substrate. Thus, the stability of the intermediate methyl 9,10-epoxystearate and the vicinal diol was significantly improved under reaction conditions. Oxidative cleavage of the vicinal diol as a stable intermediate is very promising reaching an overall selectivity of 90% and a selectivity towards the cleavage carboxylic acids of 80%, considering dilution and acidity as the most important parameters. Retention of the catalyst via organic solvent nanofiltration was investigated and we retained 94% of the catalyst in the monophasic system as the first step towards a process concept for a product purification or catalyst recycling strategy.

description: Nuclear-weapon-material detection via gamma-ray sensing is routinely applied, for example, in monitoring cross-border traffic. Natural or deliberate shielding both attenuates and distorts the shape of the gamma-ray spectra of specific radionuclides, thereby making such routine applications challenging. We develop a Lagrange multiplier (LM) test for shielding. A strong advantage of the LM test is that it only requires fitting a much simpler model that assumes no shielding. We show that, under the null hypothesis and some mild regularity conditions and as the detection time increases, LM test statistic for (composite) shielding is asymptotically Chi-square with the degree of freedom equal to the presumed number of shielding materials. We also derive the local power of the LM test. Extensive simulation studies suggest that the test is robust to the number and nature of the intervening materials, which owes to the fact that common intervening materials have broadly similar attenuation functions.

Salpeter normalization of the Stellar Initial Mass Function for massive galaxies at z~1

description: The stellar initial mass function (IMF) is a key parameter to study galaxy evolution. Here we measure the IMF mass normalization for a sample of 68 field galaxies in the redshift range 0.7 to 0.9 within the Extended Groth Strip. To do this we derive total (stellar + dark matter) mass-to-light [$(M/L)_{\rm dyn}$] using axisymmetric dynamical models. Within the region where we have kinematics (about one half-light radius), the models assume: (i) that mass-follows-light, implying negligible differences between the stellar and total density profiles; (ii) constant velocity anisotropy ($β_{\rm z}\equiv1-σ_z^2/σ_R^2=0.2$); (iii) that galaxies are seen at the average inclination for random orientations (i.e. $i=60^\circ$, where $i=90^\circ$ represents edge-on). The dynamical models are based on anisotropic Jeans equations, constrained by HST/ACS imaging and the central velocity dispersion of the galaxies, extracted from good-quality spectra taken by the DEEP2 survey. The population $(M/L)_{\rm pop}$ are derived from full-spectrum fitting of the same spectra with a grid of simple stellar population models. Recent dynamical modelling results by the $ATLAS^{3D}$ project and numerical simulations of galaxy evolution indicate that the dark matter fraction within the central regions of our galaxies should be small. This suggest that our derived total $(M/L)_{\rm dyn}$ should closely approximate the stellar $M/L$. Our comparison of $(M/L)_{\rm dyn}$ and $(M/L)_{\rm pop}$ then imply that for galaxies with stellar mass $M_\odot \geq 10^{11}$ $M_{\odot}$, the $average$ normalization of the IMF is consistent with a Salpeter slope, with a substantial scatter. This is similar to what is found within a similar mass range for nearby galaxies.

description: We propose a hybrid optomechanical quantum system consisting of a moving membrane strongly coupled to an ensemble of N atoms with a Rydberg state. Due to the strong van-der-Waals interaction between the atoms, the ensemble forms an effective two-level system, a Rydberg superatom, with a collectively enhanced atom-light coupling. Using this superatom imposed collective enhancement strong coupling between membrane and superatom is feasible for parameters within the range of current experiments. The quantum interface to couple the membrane and the superatom can be a pumped single mode cavity, or a laser field in free space, where the Rydberg superatom and the membrane are spatially separated. In addition to the coherent dynamics, we study in detail the impact of the typical dissipation processes, in particular the radiative decay as a source for incoherent superpositions of atomic excitations. We identify the conditions to suppress these incoherent dynamics and thereby a parameter regime for strong coupling. The Rydberg superatom in this hybrid system serves as a toolbox for the nanomechanical resonator allowing for a wide range of applications such as state transfer, sympathetic cooling and non-classical state preparation. As an illustration, we show that a thermally occupied membrane can be prepared in a non-classical state without the necessity of ground state cooling.

description: Using data from the SDSS-DR7, including structural measurements from 2D surface brightness fits with GIM2D, we show how the fraction of quiescent galaxies depends on galaxy stellar mass $M_*$, effective radius $R_e$, fraction of $r-$band light in the bulge, $B/T$, and their status as a central or satellite galaxy at $0.010.3$ are excluded. For satellite galaxies, the quiescent fraction is always larger than that of central galaxies, for any combination of $M_*$, $R_e$ and $B/T$. The quenching efficiency is not constant, but reaches a maximum of $\sim 0.7$ for galaxies with $9 < \log(M_*/M_\odot) < 9.5$ and $R_e<1$ kpc. This is the same region of parameter space in which the satellite fraction itself reaches its maximum value, suggesting that the transformation from an active central galaxy to a quiescent satellite is associated with a reduction in $R_e$ due to an increase in dominance of a bulge component.

description: The variances of most economic time series display marked fluctuations over time. Panel unit root tests of the so-called first and second generation are not robust in such cases. In response to this problem, a few heteroskedasticity-robust panel unit root tests have been proposed. An important limitation of these tests is, however, that they become invalid if the data are trending. As a prominent means of drift adjustment under the panel unit root hypothesis, the (unweighted) forward detrending scheme of Breitung suffers from nuisance parameters if the data feature time-varying variances. In this article, we propose a weighted forward-detrending scheme. Unlike its unweighted counterpart, the new detrending scheme restores the pivotalness of the heteroskedasticity-robust panel unit root tests suggested by Demetrescu and Hanck and Herwartz et al. when applied to trending panels with heteroskedastic variances. As an empirical illustration, we provide evidence in favor of non-stationarity of health care expenditures as shares of GDP in a panel of OECD economies.

description: The generalized persistence (GP) model, developed in the context of estimating ``value added'' by individual teachers to their students' current and future test scores, is one of the most flexible value-added models in the literature. Although developed in the educational setting, the GP model can potentially be applied to any structure where each sequential response of a lower-level unit may be associated with a different higher-level unit, and the effects of the higher-level units may persist over time. The flexibility of the GP model, however, and its multiple membership random effects structure lead to computational challenges that have limited the model's availability. We develop an EM algorithm to compute maximum likelihood estimates efficiently for the GP model, making use of the sparse structure of the random effects and error covariance matrices. The algorithm is implemented in the package GPvam in R statistical software. We give examples of the computations and illustrate the gains in computational efficiency achieved by our estimation procedure.

description: Diese Dissertation befasst sich in drei voneinander unabhängigen Kapiteln mit dem Forschungsfeld des ökonomischen Designs. Das "Design" von Situationen wirtschaftlicher Interaktion hat zum Ziel, den Verlauf und das Ergebnis der jeweiligen Interaktion zu steuern. In dieser Arbeit werden mathematisch-theoretische "Designs" zum einen formal entwickelt und diese zum anderen durch politische oder soziale Institutionen realisiert. Das erste Kapitel thematisiert die Implementierung von Sozialwahlfunktionen in einem kollusiven Umfeld. Es wird gezeigt, wie die gezielte Schaffung von asymmetrischer Information zwischen den kolludierenden Parteien deren Koordination erschweren und die Implementierung erleichtern kann. Im zweiten Kapitel wird dieser Ansatz im Kontext der Bestechlichkeit bei Finanzaudits angewendet. Korruption kann verhindert werden, wenn der bestechliche Akteure eine Warnung über anstehende Kontrollen erhält, nicht jedoch der bestechende Akteur. Das dritte Kapitel wiederum untersucht "Design" in Form von Markt- und Wettbewerbsregulierung. Eine Beschränkung des Wettbewerbs - durch eine Begrenzung der Zahl miteinander konkurrierender Firmen - kann entgegen der ökonomischen Intuition wohlfahrtsoptimierend sein.
description: This thesis contributes to the field of economic design in three independent chapters. Taking the perspective of a "designer", it derives formal solutions in the framework of economic theory and suggests political as well as social institutions to put these solutions to practice. The first chapter employs mechanism design to mitigate the problem of collusion. It shows how the implementation of social choice functions can be achieved by introducing asymmetric information into a system prone to collusion. In the second chapter, this methodology is applied to the context of corruption in auditing. Bribery is impeded by selectively warning one - and only one - of the corruptive parties about upcoming inspections. Finally, the third chapter studies market regulation as a means of "design". Contrary to economic intuition, it may be beneficial in terms of welfare to limit competition by restricting the number of firms allowed to enter a market.

description: This article suggests new panel unit root tests that allow for multiple structural breaks and control for cross-correlations in the panel. Breaks are modeled with a Fourier function, which allows for smooth or gradual change rather than abrupt breaks. Cross-correlations are corrected by using the PANIC procedure. The simulations show that our tests have good size and power properties and perform reasonably well when the nature of breaks or the factor structure is unknown. The new panel unit root tests support fresh evidence on the persistence of healthcare expenditures in OECD countries.
Tunguska, ecco dove cercare la meteorite

Il 30 giugno 1908 era da poco sorta l’alba, lungo le rive del fiume Tunguska, nella Siberia centrale, quando si verificò quello che viene considerato l’impatto del millennio: un’esplosione da 15 megatoni prodotta  probabilmente da un meteoroide di circa 50-80 metri di diametro. Non è mai stato ritrovato. È il grande mistero di Tunguska. Ora uno studio guidato da tre ricercatori dell’Istituto nazionale di astrofisica ha calcolato in quale zona cercare eventuali frammenti

description: We consider a two-asset non-linear model of option pricing in an environment where the correlation is not known precisely, but varies between two known values. First we discuss the non-negativity of the solution of the equation. Next, we construct and analyze a positivity preserving, flux-limited difference scheme for the corresponding boundary value problem. Numerical experiments are analyzed.
Relationship between LTA4H promotor polymorphism and tuberculosis-associated immune reconstitution inflammatory syndrome and its prevention with prednisone.

description: The development of paradoxical tuberculosis-associated immune reconstitution inflammatory syndrome (TB-IRIS) and its prevention using prednisone may potentially be mediated by the LTA4H genotype. We assessed this hypothesis in a clinical trial evaluating prednisone to prevent TB-IRIS. We did not find an association between LTA4H genotype and TB-IRIS incidence or prednisone efficacy.

description: When conducting regression analysis, econometricians often face the situation where some relevant regressors are unavailable in the data set at hand. This article shows how to construct a new class of nonparametric proxies by combining the original data set with one containing the missing regressors. Imputation of the missing values is done using a nonstandard kernel adapted to mixed data. We derive the asymptotic distribution of the resulting semiparametric two-sample estimator of the parameters of interest and show, using Monte Carlo simulations, that it dominates the solutions involving instrumental variables and other parametric alternatives. An application to the PSID and NLS data illustrates the importance of our estimation approach for empirical research.

title: Transmitting Development: Global Networks and Local Grids in the Electrification of East Africa, 1906-1970
Creators: name: Straeten, Jonas van der
Publisher: name: UNSPECIFIED
Year: 2023

description: Transmitting Development provides a comprehensive archive-based historical account of the electrification of East Africa, covering British colonial Kenya, Uganda, and Tanganyika until political independence, and Tanzania until the present day. Departing from the national histories of electricity prevalent in the history of technology, it focuses on the global interconnections and interdependencies in electrification processes. The author argues that electrification in East Africa was shaped by concepts and interests from outside the continent, most notably by ideas of development and the strive for profit. Until today, the agents of transfer of these ideas represent a relatively small subset of international consultants, private investors, and government officials who control and manage many of the most sensitive aspects of infrastructural development.

description: A comparative study of 41 sample gins in the San Joaquin Valley of California in 1972/73 with the previous season revealed higher overall averages in rated ginning capacities, annual volumes ginned, and in plant capacity utilization. Operating cost averages, per bale, ranged from $16.27 for out-of-pocket to $21.64 for total standardized costs; down $2.59 and $5.03, respectively, from 1971/72. Ginning revenues from all sources combined, for independents and some cooperatives in the sample, were almost identical both seasons. A stepwise multiple linear regression analysis revealed that volume ginned was the most influential factor in determining annual gin operating costs.
