description: Background: Eclipse effect of the neutron and proton in a deuteron target is essential to correctly describe high-energy deuteron scattering. The nucleus-deuteron scattering needs information not only on the nucleus-proton but also the nucleus-neutron interaction, for which no direct measurement of the nucleus-neutron cross sections is available for unstable nuclei. Purpose: We systematically evaluated the total reaction cross sections by a deuteron target to explore the feasibility of extracting the nucleus-neutron interaction from measurable cross sections. Methods: High-energy nucleus-deuteron collision is described by the Glauber model, in which the proton and neutron configuration of the deuteron is explicitly taken into account. Results: Our calculation reproduces available experimental total reaction cross section data on the nucleus-deuteron scattering. The possibility of extracting the nucleus-neutron total reaction cross section from nucleus-deuteron and nucleus-proton total reaction cross sections is explored. The total reaction cross sections of a nucleus by proton, neutron, and deuteron targets can be expressed, to good accuracy, in terms of the nuclear matter radius and neutron skin thickness. Incident-energy dependence of the total reaction cross sections is examined. Conclusions: The total reaction cross section on a deuteron target includes information on both the nucleus-neutron and nucleus-proton profile functions. Measuring the cross sections by deuteron and proton targets is a promising tool to extract the nuclear size properties.

description: This is an elementary introduction to a method for studying harmonic maps into symmetric spaces, and in particular for studying constant mean curvature (CMC) surfaces, that was developed by J. Dorfmeister, F. Pedit and H. Wu. There already exist a number of other introductions to this method, but all of them require a higher degree of mathematical sophistication from the reader than is needed here. The authors' goal was to create an exposition that would be readily accessible to a beginning graduate student, and even to a highly motivated undergraduate student. Constant mean curvature surfaces in Euclidean 3-space, and also spherical 3-space and hyperbolic 3-space, are described, along with the Lax pair equations that determine their frames. The simplest examples, including Delaunay surfaces and Smyth surfaces, are described in detail.

description: Nearly a century after the first reports of Rift Valley fever (RVF) were documented in Kenya, questions on the transmission dynamics of the disease remain. Specifically, data on viral maintenance in the quiescent years between epidemics is limited. We implemented a cross-sectional study in northern Kenya to determine the seroprevalence, risk factors, and ecological predictors of RVF in humans and livestock during an interepidemic period. Six hundred seventy-six human and 1,864 livestock samples were screened for anti-RVF Immunoglobulin G (IgG). Out of the 1,864 livestock samples tested for IgG, a subset of 1,103 samples was randomly selected for additional testing to detect the presence of anti-RVFV Immunoglobulin M (IgM). The anti-RVF virus (RVFV) IgG seropositivity in livestock and humans was 21.7% and 28.4%, respectively. RVFV IgM was detected in 0.4% of the livestock samples. Participation in the slaughter of livestock and age were positively associated with RVFV exposure in humans, while age was a significant factor in livestock. We detected significant interaction between rainfall and elevation's influence on livestock seropositivity, while in humans, elevation was negatively associated with RVF virus exposure. The linear increase of human and livestock exposure with age suggests an endemic transmission cycle, further corroborated by the detection of IgM antibodies in livestock.

description: En la presente tesis se realiza un análisis del Control Interno como medio de la función administrativa en el Estado colombiano a partir de la teoría del Derecho Anticipativo y la Cultura de la Anticipación, teoría creada y desarrollada por el profesor Juan Carlos Peláez Gutiérrez. Se asume que el Control Interno puede constituir un instrumento del Derecho Anticipativo en la gestión y administración del riesgo. Para el efecto se aborda el Control Interno considerado como un control del primer grado o del primer nivel y complementario del Control Fiscal; asimismo, el análisis recurre a la visión administrativa orientada por los avances del Método Estándar de Control Interno (MECI), integrado para el cumplimiento misional de las entidades. Lo cual genera diferencias apreciativas sobre el deber ser de su desempeño. Estas discrepancias hoy se encuentran irresolutas. Por ello en esta tesis realiza una revisión de la relación entre la orientación que sigue el Control Fiscal y el trabajo que se ejecuta en el Control Interno.
description: In this thesis an analysis of Internal Control is carried out as a means of administrative function in the Colombian State based on the theory of Anticipatory Law and the Culture of Anticipation, a theory created and developed by Professor Juan Carlos Peláez Gutiérrez. It is assumed that Internal Control can constitute an instrument of Anticipatory Law in risk management and administration. For this purpose, Internal Control is addressed, considered as a control of the first degree or first level and complementary to Fiscal Control; Likewise, the analysis uses the administrative vision guided by the advances of the Standard Method of Internal Control (MECI), integrated into the missionary compliance process of the entities. Which generates appreciative differences about the duty of their performance. These discrepancies today are unresolved. For this reason, in this thesis he carries out a review of the relationship between the orientation followed by Fiscal Control and the work carried out in Internal Control
Eating bitterness and eating well: the role of street markets in communities in Beijing
Creators: name: Lary, Tatiana

description: Street markets are one of the most visible signs of China's economic reform. Although there had been a long tradition of street vending, such private sector activity was virtually eliminated nationwide in the Cultural Revolution (1966-1976). It was only with the reform policy of 1978 that vending began to reappear. By the mid-1990's, street markets had become the main source of vegetables and many other goods for urban residents. This qualitative study addresses the role of markets in communities in Beijing. Methods of investigation included a literature review, mapping, participant observation, and interviews of residents, vendors and government officials. Markets provide employment, a cheap source of goods and a vibrant street life, but also bring problems of noise, waste, and traffic congestion. Problems vary according to the location of the markets. Vending is more strictly controlled in the inner city where streets are narrow and greater supervision is in place. There is more space in the outer city, where there are both more legal markets and more illegal vendors. Residents are dependent on markets for most foods, but are adversely affected by the negative aspects of markets. Results of the study indicate that many Beijing markets are poorly managed, in part because of the conflict of interest between different levels of government. Higher levels of government see markets as a backwards and disorderly phenomenon, and try to impose order by limiting the number of legal markets and vendors. Lower levels of government want to increase the number of vendors, and thus the revenue from management fees. In 1996, the Beijing government adopted a market clearance policy to reduce the total number of markets, and move street markets indoors. This policy seems unrealistic; it underestimates both the demand for street markets and the difficulty and cost of finding land for indoor markets. Recommendations stemming from the study focus on improving the current situation of street markets by applying more rigorous and consistent management, not by closing markets down. Street markets have brought many benefits to Beijing residents; with better management the adverse effects of markets can be minimized.

description: Massive MIMO is one of the main features of 5G mobile radio systems. However, it often leads to high cost, size and power consumption. To overcome these issues, the use of constrained radio frequency (RF) frontends has been proposed, as well as novel precoders, e.g., a multi-antenna, greedy, iterative and quantized precoding algorithm (MAGIQ). Nevertheless, the best performance of MAGIQ assumes accurate channel knowledge per antenna element, for example, from uplink sounding reference signals. In this context, we propose an efficient uplink channel estimator by applying machine learning (ML) algorithms. In a first step a conditional generative adversarial network (cGAN) predicts the radio channels from a limited set of full resolution RF chains to the rest of the low resolution RF chain antenna elements. A long-short term memory (LSTM) neural network extracts further phase information from the low resolution RF chain antenna elements. Our results indicate that our proposed approach is competitive with traditional Unitary tensor-ESPRIT in scenarios with various closely spaced multipath components (MPCs).

description: Brucella spp. and Rift Valley fever virus (RVFV) are classified as priority zoonotic agents in Kenya, based on their public health and socioeconomic impact on the country. Data on the pathogen-specific and co-exposure levels is scarce due to limited active surveillance. This study investigated seroprevalence and co-exposure of Brucella spp. and RVFV and associated risk factors among slaughterhouse workers in Isiolo County, northern Kenya. A cross-sectional serosurvey was done in all 19 slaughterhouses in Isiolo County, enrolling 378 participants into the study. The overall seroprevalences for Brucella spp. and RVFV were 40.2% (95% CI: 35.2–45.4) and 18.3% (95% CI: 14.5–22.5), respectively while 10.3% (95% CI 7.4%-13.8%) of individuals were positive for antibodies against both Brucella spp. and RVFV. Virus neutralisation tests (VNT) confirmed anti-RVFV antibodies in 85% of ELISA-positive samples. Our seroprevalence results were comparable to community-level seroprevalences previously reported in the area. Since most of the study participants were not from livestock-keeping households, our findings attribute most of the detected infections to occupational exposure. The high exposure levels indicate slaughterhouse workers are the most at-risk population and there is need for infection, prevention, and control programs among this high-risk group. This is the first VNT confirmation of virus-neutralising antibodies among slaughterhouse workers in Isiolo County and corroborates reports of the area being a high-risk RVFV area as occasioned by previously reported outbreaks. This necessitates sensitization campaigns to enhance awareness of the risks involved and appropriate mitigation measures.

description: We studied complex spectra of spin-two boson systems represented by E$\otimes$e and E$\otimes (b_1+b_2)$ Jahn-Teller models. For E$\otimes$e, at particular rotation quantum numbers we found a coexistence of up to three regions of the spectra, (i) the dimerized region of long-range ordered (extended) pairs of oscillating levels, (ii) the short-range ordered (localized) "kink lattice" of avoiding levels, and (iii) the intermediate region of kink nucleation with variable range of ordering. This structure appears above certain critical line as a function of interaction strength. The level clustering and level avoiding generic patterns reflect themselves in several intermittent regions between up-to three branches of spectral entropies. Linear scaling behavior of the widths of curvature probability distributions provides the conventionally adopted indication for the presence of quantum chaos. The mapping onto classical integrable Calogero-Moser gas provided useful insight into the complex level dynamics, including the soliton collisions representing the level avoidings and, in a range of model parameters, a novel view on the notion of quantum chaos formulated in terms of quantum numbers via the logistic equation. We found that apart from two limiting cases of $E\otimes(b_1+b_2)$ model ($E\otimes e$ and Holstein model) the distribution of nearest neighbor spacings of this model is rather stable as to the change of parameters and different from Wigner one. This limiting distribution assumably shows scaling $\sim\sqrt{S}$ at small $S$ and resembles the semi-Poisson law $P(S)= 4S \exp (-2 S)$ at $S\geq 1$. The latter is believed to be universal and characteristic, e.g. at the transition between metal and insulator phases.

description: Welchen Ort hat Literatur in flüchtiger Zeit? Worin liegt die Aufgabe des gedruckten Buchstabens, heute wie einst Medium beständiger Fixierung und Hort dauerhafter Aufbewahrung, verglichen mit den digitalisierten Zeichenwelten einer elektronischen Schreibkultur? Gibt es auf dem gemeinsamen Grund des analogen und des digitalen Worts, von allen Unterschieden abgesehen, möglicherweise so etwas wie ein nomadisches Schreiben? Wie begegnen literarische Werke allgemeiner den universalen Bewegungen ihrer globalisierten Gegenwart? Bilden sie Stätten der Ruhe und der Kontemplation oder werden sie selbst zu Räumen der Unrast und des Aufruhrs? Auf solche und ähnliche Fragen antwortet dieses Buch anhand der ersten groß angelegten Untersuchung zum Nomadischen in der deutschsprachigen Gegenwartsliteratur. Es komplementiert die „Theorie des Nomadischen“ (2024) durch eine Analyse zum Werk von Christoph Ransmayr, in dessen Schaffen das nomadische Argument eine konzentrierte Grundlage und Gestalt gewinnt. In der gezielt gegenstandsnahen Auseinandersetzung mit ihm werden theoretische Positionen erweitert und vertieft, in der Medialität des Materials interpretative Horizonte über das Literarische hinausgeführt. „Signaturen“ sind epochale „Kennzeichen“ ebenso wie mediale „Zeichenzusammenhänge“, die auch multiple Bild- und Klangereignisse einschließen. Die Spannweite reicht von der intermedialen Konfiguration aus Text, Bild, Ton über den Roman bis zum episodischen Erzählen zwischen poetischem und publizistischem Arbeiten. An den geisterhaften Übergängen von Heim und Heimsuchung, Ökologie und Ökonomie, sprachlicher und kolonialer Gewalt werden geschichtliche Größen von der antiken Literatur bis zu Film und Serialität zum Leben erweckt. In der Konzentration auf kanonische Schlüsselwerke des Autors samt deren textuellen und medialen Variationen aus vier Jahrzehnten liefert das Buch zugleich die bislang umfassendste Studie zu Ransmayrs Œuvre überhaupt. Sie erscheint im Jahr seines 70. Geburtstags.

The basic idea consists in considering separately each equation of this system and incorporating a loping strategy. The first technique is a Kaczmarz-type method, equipped with a novel stopping criteria. The second method is obtained using an embedding strategy, and again a Kaczmarz-type approach. We prove well-posedness, stability and convergence of both methods.

description: The Andreev spectrum of a quantum dot embedded in a hybrid semiconductor-superconductor interferometer can be modulated by electrostatic gating, magnetic flux through the interferometer, and Zeeman splitting from in-plane magnetic field. We demonstrate parity transitions in the embedded quantum dot system, and show that the Zeeman-driven transition is accompanied by a 0-π transition in the superconducting phase across the dot. We further demonstrate that flux through the interferometer modulates both dot parity and 0-π transitions.

description: We report on a large-scale study of student learning of quantum tunneling in 4 traditional and 4 transformed modern physics courses. In the transformed courses, which were designed to address student difficulties found in previous research, students still struggle with many of the same issues found in other courses. However, the reasons for these difficulties are more subtle, and many new issues are brought to the surface. By explicitly addressing how to build models of wave functions and energy and how to relate these models to real physical systems, we have opened up a floodgate of deep and difficult questions as students struggle to make sense of these models. We conclude that the difficulties found in previous research are the tip of the iceberg, and the real issue at the heart of student difficulties in learning quantum tunneling is the struggle to build the complex models that are implicit in experts' understanding but often not explicitly addressed in instruction.

description: The tension between measurements of the Hubble constant obtained at different redshifts may provide a hint of new physics active in the relatively early universe, around the epoch of matter-radiation equality. A leading paradigm to resolve the tension is a period of early dark energy, in which a scalar field contributes a subdominant part of the energy budget of the universe at this time. This scenario faces significant fine-tuning problems which can be ameliorated by a non-trivial coupling of the scalar to the standard model neutrinos. These become non-relativistic close to the time of matter-radiation equality, resulting in an energy injection into the scalar that kick-starts the early dark energy phase, explaining its coincidence with this seemingly unrelated epoch. We present a minimal version of this neutrino-assisted early dark energy model, and perform a detailed analysis of its predictions and theoretical constraints. We consider both particle physics constraints -- that the model constitute a well-behaved effective field theory for which the quantum corrections are under control, so that the relevant predictions are within its regime of validity -- and the constraints provided by requiring a consistent cosmological evolution from early through to late times. Our work paves the way for testing this scenario using cosmological data sets.

description: We study interacting scalar field theory non-minimally coupled to gravity in the FRW background. We show that for a specific choice of interaction terms, the energy-momentum tensor of the scalar field vanishes, and as a result the scalar field does not gravitate. The naive space dependent solution to equations of motion gives rise to singular field profile. We carefully analyze the energy-momentum tensor for such a solution and show that the singularity of the solution gives a subtle contribution to the energy-momentum tensor. The space dependent solution therefore is not non-gravitating. Our conclusion is applicable to other space-time dependent non-gravitating solutions as well. We study hybrid inflation scenario in this model when purely time dependent non-gravitating field is coupled to another scalar field.

Exploiting symmetries and progressive refinement for apodized pupil Lyot coronagraph design

description: Modern coronagraph design relies on advanced, large-scale optimization processes that require an ever increasing amount of computational resources. In this paper, we restrict ourselves to the design of Apodized Pupil Lyot Coronagraphs (APLCs). To produce APLC designs for future giant space telescopes, we require a fine sampling for the apodizer to resolve all small features, such as segment gaps, in the telescope pupil. Additionally, we require the coronagraph to operate in broadband light and be insensitive to small misalignments of the Lyot stop. For future designs we want to include passive suppression of low-order aberrations and finite stellar diameters. The memory requirements for such an optimization would exceed multiple terabytes for the problem matrix alone. We therefore want to reduce the number of variables and constraints to minimize the size of the problem matrix. We show how symmetries in the pupil and Lyot stop are expressed in the complete optimization problem, and allow removal of both variables and constraints. Each mirror symmetry reduces the problem size by a factor of four. Secondly, we introduce progressive refinement, which uses low-resolution optimizations as a prior for higher resolutions. This lets us remove the majority of variables from the high-resolution optimization. Together these two improvements require up to 256x less computer memory, with a corresponding speed increase. This allows for greater exploration of the phase space of the focal-plane mask and Lyot-stop geometry, and easier simulation of sensitivity to Lyot-stop misalignments. Moreover, apodizers can now be optimized at their native manufactured resolution.

description: In this paper we present a Bayesian reinforcement learning framework that allows robotic manipulators to adaptively recover from random mechanical failures autonomously, hence being survivable. To this end, we formulate the framework of Bayesian Policy Morphing (BPM) that enables a robot agent to self-modify its learned policy after the diminution of its maneuvering dimensionality. We build upon existing actor-critic framework, and extend it to perform policy gradient updates as posterior learning, taking past policy updates as prior distributions. We show that policy search, in the direction biased by prior experience, significantly improves learning efficiency in terms of sampling requirements. We demonstrate our results on an 8-DOF robotic arm with our algorithm of BPM, while intentionally disabling random joints with different damage types like unresponsive joints, constant offset errors and angular imprecision. Our results have shown that, even with physical damages, the robotic arm can still successfully maintain its functionality to accurately locate and grasp a given target object.

description: A new purely algebraic algorithm is presented for computation of invariants (generalized Casimir operators) of Lie algebras. It uses the Cartan's method of moving frames and the knowledge of the group of inner automorphisms of each Lie algebra. The algorithm is applied, in particular, to computation of invariants of real low-dimensional Lie algebras. A number of examples are calculated to illustrate its effectiveness and to make a comparison with the same cases in the literature. Bases of invariants of the real solvable Lie algebras up to dimension five, the real six-dimensional nilpotent Lie algebras and the real six-dimensional solvable Lie algebras with four-dimensional nilradicals are newly calculated and listed in tables.

description: We present doubly-periodic solutions of the infinitely extended nonlinear Schrodinger equation with an arbitrary number of higher-order terms and corresponding free real parameters. Solutions have one additional free variable parameter that allows to vary periods along the two axes. The presence of infinitely many free parameters provides many possibilities in applying the solutions to nonlinear wave evolution. Being general, this solution admits several particular cases which are also given in this work.

Comment: The original description of O. hispanica is based on a larger number ("in grösserer Anzahl") of syntypes from "Nordspanien (Palencia)" and few specimens ("einzelne Stücke") from "Navacenada" and "Badajoz" (BERNHAUER 1914). Nine syntypes from Palencia were located in the Bernhauer collection at the FMNH; one of the males is designated as the lectotype. The species is conspecific with O. virgata ASSING 2008, whose description is based on numerous specimens from Andalucía and Castilla-La Mancha; hence the synonymy proposed above. For an illustration of the median lobe of the aedeagus and the spermatheca of the lectotype and a paralectotype, respectively, see Figs 44-45. The aedeagus of O. virgata is illustrated in ASSING (2008).
Oxypoda hispanica had been recorded only from Spain, where it is widespread and apparently not particularly rare. The above specimens from the Haut Atlas represent the first records from Morocco (Map 5).
