description: One of the most critical tasks in tractor operation is the accurate steering during field operations, e.g., accurate trajectory following during mechanical weeding or spraying, to avoid damaging the crop or planting when there is no crop yet. To automate the trajectory following problem of an autonomous tractor-trailer system and also increase its steering accuracy, a nonlinear model predictive control approach has been proposed in this paper. For the state and parameter estimation, moving horizon estimation has been chosen since it considers the state and the parameter estimation within the same problem and also constraints both on inputs and states can be incorporated. The experimental results show the accuracy and the efficiency of the proposed control scheme in which the mean values of the Euclidean error for the tractor and the trailer, respectively, are 6.44 and 3.61 cm for a straight line trajectory and 49.78 and 41.52 cm for a curved line trajectory.

description: A tiny fraction of observed gamma-ray bursts (GRBs) may be lensed. The time delays induced by the gravitational lensing are milliseconds to seconds if the point lenses are intermediate-mass black holes. The prompt emission of the lensed GRBs, in principle, should have repeated pulses with identical light curves and spectra but different fluxes and slightly offset positions. In this work, we search for such candidates within the GRBs detected by Fermi/GBM, Swift/BAT, and HXMT/HE and report the identification of an attractive event GRB 200716C that consists of two pulses. Both the autocorrelation analysis and the Bayesian inference of the prompt emission light curve are in favor of the gravitational lensing scenario. Moreover, the spectral properties of the two pulses are rather similar and follow the so-called Amati relation of short GRBs rather than long duration bursts. The measured flux ratios between the two pulses are nearly constant in all channels, as expected from gravitational lensing. We therefore suggest that the long duration burst GRB 200716C was a short event being lensed. The redshifted mass of the lens was estimated to be $4.25^{+2.46}_{-1.36}$ $\times$ $10^5$ $M_{\odot}$ (90$\%$ credibility). If correct, this could point towards the existence of an intermediate-mass black hole along the line of sight of GRB 200716C.

description: Stimulated by the newly reported doubly-charmed tetraquark state $T_{cc}^+$ by LHCb, we carry out a systematic investigation of the $S$-wave interactions between the charmed meson ($D,\,D^{*}$) in $H$-doublet and the charmed meson ($D_{1},\,D_{2}^{*}$) in $T$-doublet by adopting the one-boson-exchange model. Both the $S$-$D$ wave mixing effect and the coupled channel effect are taken into account. By performing a quantitative calculation, we suggest that the $S$-wave $D^{*} D_{1}$ states with $I(J^{P})=0(0^{-},\,1^{-})$ and the $S$-wave $D^{*}D_{2}^{*}$ state with $I(J^{P})=0(1^{-})$ should be viewed as the most promising candidates of the doubly-charmed molecular tetraquark states, and the $S$-wave $DD_{1}$ state with $I(J^{P})=0(1^{-})$, the $S$-wave $DD_{2}^{*}$ state with $I(J^{P})=0(2^{-})$, and the $S$-wave $D^{*}D_{2}^{*}$ state with $I(J^{P})=0(2^{-})$ are the possible doubly-charmed molecular tetraquark candidates. With the accumulation of experimental data at Run III and after High-Luminosity-LHC upgrade, these predicted doubly-charmed molecular tetraquark states can be accessible at LHCb in the near future.

description: In recent years the goal of estimating different cosmological parameters precisely has set new challenges in the effort to accurately measure the angular power spectrum of CMB. This has required removal of foreground contamination as well as detector noise bias with reliability and precision. Recently, a novel {\em model-independent} method for the estimation of CMB angular power spectrum solely from multi-frequency observations has been proposed and implemented on the first year WMAP data by Saha et al. 2006. All previous estimates of power spectrum of CMB are based upon foreground templates using data sets from different experiments. However our methodology demonstrates that {\em CMB angular spectrum can be reliably estimated with precision from a self contained analysis of the WMAP data}. In this work we provide a detailed description of this method. We also study and identify the biases present in our power spectrum estimate. We apply our methodoly to extract the power spectrum from the WMAP 1 year and 3 year data.

description: Quantum computation represents a threat to many cryptographic protocols in operation today. It has been estimated that by 2035, there will exist a quantum computer capable of breaking the vital cryptographic scheme RSA2048. Blockchain technologies rely on cryptographic protocols for many of their essential sub-routines. Some of these protocols, but not all, are open to quantum attacks. Here we analyze the major blockchain-based cryptocurrencies deployed today -- including Bitcoin, Ethereum, Litecoin and ZCash, and determine their risk exposure to quantum attacks. We finish with a comparative analysis of the studied cryptocurrencies and their underlying blockchain technologies and their relative levels of vulnerability to quantum attacks.

description: The cosmic near-infrared background (NIRB) offers a powerful integral probe of radiative processes at different cosmic epochs, including the pre-reionization era when metal-free, Population III (Pop III) stars first formed. While the radiation from metal-enriched, Population II (Pop II) stars likely dominates the contribution to the observed NIRB from the reionization era, Pop III stars -- if formed efficiently -- might leave characteristic imprints on the NIRB thanks to their strong Ly$α$ emission. Using a physically-motivated model of first star formation, we provide an analysis of the NIRB mean spectrum and anisotropy contributed by stellar populations at $z>5$. We find that in circumstances where massive Pop III stars persistently form in molecular cooling haloes at a rate of a few times $10^{-3}\,M_\odot \ \mathrm{yr}^{-1}$, before being suppressed towards the epoch of reionization (EoR) by the accumulated Lyman-Werner background, a unique spectral signature shows up redward of $1\,μ$m in the observed NIRB spectrum sourced by galaxies at $z>5$. While the detailed shape and amplitude of the spectral signature depend on various factors including the star formation histories, IMF, LyC escape fraction and so forth, the most interesting scenarios with efficient Pop III star formation are within the reach of forthcoming facilities such as the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx). As a result, new constraints on the abundance and formation history of Pop III stars at high redshifts will be available through precise measurements of the NIRB in the next few years.

description: The article presents a first historical reconnaissance of the Ukrainian theatre  (from 1600 to our days), through a critical approach to the respective  historiography. The dramaturgy and the Ukrainian scene are contextualized  according to the historical-political dimension that has determined, for the  creative shapes of this Country, the evolution of the search of a "territorial -  historical identity" (with particular evidence in the theatre of the twentieth  century). Around such a characteristic there has developed a wider reflection  expressed in the preamble of the article, where some possible interactions are  hypothesized between geopolitics and studies of the theatre, in order to carry  out an adequate analysis of the cultural phenomena relative to the territories  of the ex-URSS.

Okanagana tristis rubrobasilis — [sic], Simons, 1954: 178 (Revised status to original combination and spelling error)
Okanagana rubrobasalis stat. rev. (Revised to species level as proposed by Katō, 1932).
Type Locality: Holotype: male from Nellie, San Diego Co., CA, 24 June 1918; Allotype from Upland, San Bernardino Co., CA 1 July 1920. Holotype and allotype are deposited at American Museum of Natural History (Sanborn & Heath 2017).
Rationale for status revision: Two fresh specimens were sequenced, including one from near the allotype locality of O. tristis rubrobasalis at Upland, San Bernardino Co., California (Davis 1926; Supp. Table 1). Our results found a sister relationship for O. tristis tristis + O. canescens (Figs. 5–7). Unlike O. tristis, this species exhibits a rainfall-mediated protoperiodical phenology (Chatfield-Taylor & Cole 2017) and has a southern distribution that is allopatric from O. tristis tristis. There are also measurable, consistent differences in the dominant frequency of their call (unpublished data). The clear genetic separation from O. tristis tristis (COI uncorrected distance 5.56–5.68%; Supp. Table 2), combined with differing ecology and an allopatric distribution support revising the status of O. tristis rubrobasalis to the level of species as O. rubrobasalis stat. rev. as first proposed by Katō (1932).
Description: O. rubrobasalis was originally described as a subspecies of O. tristis (Davis 1926). Major separating features from O. tristis included the blood-red wing membranes in O. rubrobasalis (Fig. 13A, B) compared to pale orange in O. tristis, a longer, red sternite VIII (Fig. 13C, D), broader wings, and the differing geographic distribution (Davis 1926). We here add that the front is strongly pronounced as in O. cruentifera rather than like O. tristis. The trapezoidal pattern of markings on the mesonotum are red and much less pronounced than the orange markings in typical O. tristis. In new specimens (which Davis seldom had) the sternites are also blood red (Figs 13B, E) rather than orange, losing this strong color gradually over time. The tergites are lined with red along their distal margins (Fig. 13A).

description: The spin-1/2 quantum Heisenberg model is studied in all spatial dimensions d by renormalization-group theory. Strongly asymmetric phase diagrams in temperature and antiferromagnetic bond probability p are obtained in dimensions d \geq 3. The asymmetry at high temperatures approaching the pure ferromagnetic and antiferromagnetic systems disappears as d is increased. However, the asymmetry at low but finite temperatures remains in all dimensions, with the antiferromagnetic phase receding to the ferromagnetic phase. A finite-temperature second-order phase boundary directly between the ferromagnetic and antiferromagnetic phases occurs in d \geq 6, resulting in a new multicritical point at its meeting with the boundaries to the paramagnetic phase. In d=3,4,5, a paramagnetic phase reaching zero temperature intervenes asymmetrically between the ferromagnetic and reentrant antiferromagnetic phases. There is no spin-glass phase in any dimension.

description: We demonstrate microwave measurements of the Andreev bound state (ABS) spectrum in planar Josephson junctions (JJs) defined in Ge high mobility two-dimensional hole gases contacted by superconducting PtSiGe. The JJs and readout circuitry are located on separate chips and inductively coupled via flip-chip bonding. For a device with $350~\mathrm{nm}$ junction length, spectroscopic signatures were consistent with the short-junction limit, with an induced superconducting gap $Δ^{*}\approx48~\mathrm{μeV}$ and transmission $τ\approx 0.94$. The interaction between the highest-transmission ABS and the resonator was well described by a Jaynes-Cummings model with a vacuum Rabi splitting of approximately $6~\mathrm{MHz}$. A device with junction length of $1~μm$ showed an ABS spectrum consistent with a long junction model. Time-resolved monitoring of the readout resonator in the dispersive regime revealed gate-voltage tunable junction parity fluctuations on the timescale of seconds. Our work indicates a viable path towards hybrid quantum devices based on planar Ge.

description: Few-shot anomaly detection (FSAD) plays a crucial role in industrial manufacturing. However, existing FSAD methods encounter difficulties leveraging a limited number of normal samples, frequently failing to detect and locate inconspicuous anomalies in the spatial domain. We have further discovered that these subtle anomalies would be more noticeable in the frequency domain. In this paper, we propose a Dual-Path Frequency Discriminators (DFD) network from a frequency perspective to tackle these issues. The original spatial images are transformed into multi-frequency images, making them more conducive to the tailored discriminators in detecting anomalies. Additionally, the discriminators learn a joint representation with forms of pseudo-anomalies. Extensive experiments conducted on MVTec AD and VisA benchmarks demonstrate that our DFD surpasses current state-of-the-art methods. The code is available at \url{https://github.com/yuhbai/DFD}.

description: Bereits ein kurzer Blick auf die Spitzenverbände der freien Wohlfahrtspflege zeigt, dass Religion und Soziale Arbeit nach wie vor in einer starken Verbindung stehen. Von sechs Spitzenverbänden verfügen drei Organisationen – der Caritasverband, das Diakonische Werk und die Zentralwohlfahrtsstelle der Juden – über eine enge Anbindung an Religionsgemeinschaften. Konkret bedeutet dies, dass nach wie vor ca. 1 000 000 Menschen als hauptamtliche Kräfte bei Trägern in Deutschland arbeiten, die über religiös geprägte Leitbilder verfügen. In einer Gesellschaft, die seit Dekaden einem sukzessiven Säkularisierungsprozess ausgesetzt ist und in der Kirchenaustritte in hoher Zahl den Normalfall darstellen, wird natürlich darüber diskutiert, ob eine religiös konnotierte Wohlfahrtsarbeit notwendig und zeitgemäß sein kann. Diese Diskussion hat auch die verschiedenen Handlungsfelder der Sozialen Arbeit längst erreicht und wird mit viel Verve diskutiert. Soll eine wie auch immer geartete religiöse Orientierung professionelles sozialarbeiterisches Handeln beeinflussen? Brauchen wir nicht eher neutrale bzw. säkulare Konzepte von Sozialer Arbeit? Wir leben schließlich in einer sehr heterogenen Gesellschaft, in der sich eine Vielzahl von Religions- und Weltanschauungsgemeinschaften unter einem Dach versammeln. Oder aber müssen wir die religiös konnotierten Angebote für die neu hinzugekommenen Religionsgemeinschaften ausbauen? Der konkrete Diskussionsgegenstand wäre hier eine muslimische Wohlfahrtspflege.

description: By studying the 2-dimensional Su-Schrieffer-Heeger-Bose-Hubbard model, we show the existence of topological Higgs amplitude modes in the strongly interacting superfluid phase. Using the slave boson approach, we find that, in the large filling limit, the Higgs excitations and the Goldstone excitations above the ground state are well decoupled, and both of them exhibit nontrivial topology inherited from the underlying noninteracting bands. At finite fillings, they become coupled at high energies; nevertheless, the topology of these modes are unchanged. Moreover, based on an effective action analysis, we further provide a universal physical picture for the topological character of Higgs and Goldstone modes. Our discovery of the first realization of the topological Higgs mode opens the path to novel investigations in various systems such as superconductors and quantum magnetism.

A compact, flexible controller for PWM inverters
Creators: name: Mauch, Konrad
Publisher: name: University of British Columbia
Year: 2010

description: A flexible, low cost inverter controller for use in variable speed AC motor drives has been designed. Originally designed for use in a submersible thruster drive, the controller has been found to have potential for use in other drives as well. Low cost and small size are made possible by the use of large scale integrated circuits. Flexibility in a variety of motor drive applications is achieved by using a microcomputer as the heart of the controller. In comparison to other controllers for PWM inverters, this controller has the following distinctive features: i) The controller can operate the inverter to output frequencies of 400 Hz or more as opposed to maximum frequency limits of 120 Hz to 200 Hz for other controllers. ii) The controller is programmed in the C high level programming language instead of the assembly language used in other microcomputer based controllers. This allows the controller to be adapted more rapidly to new applications, iii) The controller is smaller and has a lower component count than most other controllers. As a result the controller should be more reliable, easier to package, and less expensive. After a review of AC drive technology, the objectives and the basic alternatives in the design of the controller are presented. The circuit design and software design of the controller are discussed. Two applications of the inverter controller are presented and the success of the design in these two applications is evaluated. Conclusions are presented on the overall success of the design and suggestions are made for improvements and further work.

description: We study how the volatility, node- or link-based, affects the evolution of social networks in simple models. The model describes the competition between order -- promoted by the efforts of agents to coordinate -- and disorder induced by volatility in the underlying social network. We find that when volatility affects mostly the decay of links, the model exhibit a sharp transition between an ordered phase with a dense network and a disordered phase with a sparse network. When volatility is mostly node-based, instead, only the symmetric (disordered) phase exists These two regimes are separated by a second order phase transition of unusual type, characterized by an order parameter critical exponent $β=0^+$. We argue that node volatility has the same effect in a broader class of models, and provide numerical evidence in this direction.

Geometrical and topological properties of the quasi-plane Szekeres model and of the plane symmetric dust model are discussed. Some related comments on the quasi-hyperbolical model are made. These properties include: (1) The pattern of expansion in the plane symmetric case, and the Newtonian model that imitates it; (2) The possibility of toroidal topology of the $t =$ const sections in the plane symmetric model; (3) The absence of apparent horizons in the quasi-plane and quasi-hyperbolic models (they are globally trapped); (4) Description of the toroidal topology in the Szekeres coordinates; (5) Interpretation of the mass function in the quasi-plane model.

However, the one-nucleon exchange calculations by using the standard 3He wave functions have failed to reproduce the strong variation of the tensor analyzing powers as a function of the angle in the c.m.

Das soziale Handeln im Islam
Creators: name: Begić, Dr. Esnaf
Publisher: name: Perspektiven - Soziale Arbeit in der Migrationsgesellschaft und muslimische Wohlfahrtspflege
Year: 2019

description: Der erste Beitrag, Das soziale Handeln im Islam, stammt aus der Feder des Islamwissenschaftlers und Theologen Esnaf Begić, der am Institut für Islamische Theologie der Universität Osnabrück lehrt. Eingangs konstatiert Begić, dass eines der „wesentlichen Merkmale des Islam“ seine Manifestation in der Praxis sei. Glauben und Handeln seien gleichermaßen bedeutsam. Dies zeige sich in zahlreichen Belegstellen des Korans, wo stets vom Glauben und Verrichten der guten Werke die Rede sei. Der Autor spricht daher nachfolgend vom Glauben und sozialen Handeln als substantiellen Merkmal derislamischen Religion, auf deren Grundlage sich eine ausdifferenzierte Ethik entwickelt habe.

description: Soziale Arbeit als Profession muss sich im Handlungsfeld Migration multiplen fachlichen Herausforderungen stellen. Wenn sie sich in einer werteplural orientierten Migrationsgesellschaft profilieren möchte, muss sie sich ihrer Multifunktionalität bewusstwerden. Dabei geht es weniger um die Vollständigkeit einer Kompetenzauflistung. Primär handelt es sich hier um eine erste Bestandsaufnahme. Der vorliegende Text befasst sich daher mit Aspekten, wie z.B. Auftragsklärung, Kompetenzen, Methoden und Qualitätsstandards der Profession. Ein weiterer Schwerpunkt in diesem Text ist die muslimische Wohlfahrtspflege. Dazu werden Themenfelder vorgestellt, in denen künftig geforscht werden sollen.

description: Der vorliegende Beitrag befasst sich zunächst mit den Entwicklungen der Muslim*innen in Deutschland. Anhand bestimmter Situationen werden Herausforderungen für die Soziale Arbeit abgeleitet. Am Beispiel der Gleichberichtung der Frauen versucht der Autor herauszuarbeiten, warum es von großer Wichtigkeit ist, Soziale Arbeit und islamische Theologie miteinander zu verknüpfen, um entsprechende soziale Dienste anbieten zu können. Ergänzend dazu wird die muslimische Wohlfahrtspflege in drei verschiedenen politischen Kontexten gesetzt: 1.) Wohlfahrtspflege für eine vielfältigere Gesellschaft, 2.) Wohlfahrtspflege als Thema der Deutschen Islam Konferenz und 3.) Wohlfahrtspflege als Thema säkularer Migrant*innenorganisationen. In einem Zwischenfazit werden wesentliche Erkenntnisse kurz wiedergegeben. Die Rolle der Sozialen Arbeit bleibt dabei kontinuierlich mitberücksichtigt.

Performance of Kalman decision-feedback equalization in HF radio modems
Creators: name: Tront, Russell John
Publisher: name: University of British Columbia
Year: 2010

description: The performance of fast-adapting Kalman algorithms in adjusting the tap weights of digital equalizers for high-speed, serial HF radio modems is investigated. Experiments on a large realistic set of simulated HF channels, and on some actual channels, have been conducted using 2400 bps QPSK. Results are presented for linear and decision-feedback equalizers with symbol and half-symbol (fractionally) spaced taps. The bit error rate and the optimum values of several algorithmic parameters in reference-directed mode, and the relative resistance of the various configurations to "crashing" in decision-directed mode, have been determined as a function of the channel characteristics. The results show the superiority of the Kalman, fractionally-tapped decision-feedback equalizer and point out the uniqueness and relative difficulty of equalizing the HF radio channel. At slow fade rates, reference-directed performance within 3-5 dB of optimum is possible. With fade rates above 0.5 Hz though, the technique becomes fade-rate limited. A theoretical argument leads to a new definition of a "slow fading channel" for exponentially-aged Kalman equalizers. Performance in decision-directed mode, necessary for actual communication, was much poorer than expected. It was concluded that the continously-high Kalman Gain necessary on the HF channel results in such adaptation at each iteration that even isolated decision errors can seriously disrupt the adaptation process. In spite of the decision-directed degradation, the serial equalizer technique is shown superior to currently-used parallel modems if the fade rate is less than 0.5 Hz and the transmissions are peak power limited.
Tuning and Amplifying the Interactions in Superconducting Quantum Circuits with Subradiant Qubits

description: We propose a tunable coupler consisting of N fixed-frequency qubits, which can tune and even amplify the effective interaction between two superconducting quantum circuits. The tuning range of the interaction is proportional to N, with a minimum value of zero and a maximum that can exceed the physical coupling rates between the coupler and the circuits. The effective coupling rate is determined by the collective magnetic quantum number of the qubit ensemble, which takes only discrete values and is free from collective decay and decoherence. Using single-photon pi-pulses, the coupling rate can be switched between arbitrary choices of the initial and final values within the dynamic range in a single step without going through intermediate values. A cascade of the couplers for amplifying small interactions or weak signals is also discussed. These results should not only stimulate interest in exploring the collective effects in quantum information processing, but also enable development of applications in tuning and amplifying the interactions in a general cavity-QED system.

Quantum-statistical equation-of-state models of dense plasmas: high-pressure Hugoniot shock adiabats

Subjects: subject: Plasma Physics (physics.plasm-ph)

subject: FOS: Physical sciences

description: We present a detailed comparison of two self-consistent equation-of-state models which differ from their electronic contribution: the atom in a spherical cell and the atom in a jellium of charges. It is shown that both models are well suited for the calculation of Hugoniot shock adiabats in the high pressure range (1 Mbar-10 Gbar), and that the atom-in-a-jellium model provides a better treatment of pressure ionization. Comparisons with experimental data are also presented. Shell effects on shock adiabats are reviewed in the light of these models. They lead to additional features not only in the variations of pressure versus density, but also in the variations of shock velocity versus particle velocity. Moreover, such effects are found to be responsible for enhancement of the electronic specific heat.
