description: We analyse the rotation curves and gravitational stability of a sample of six bulgeless galaxies for which detailed images reveal no evidence for strong bars. We explore two scenarios: Newtonian dark matter models and MOdified Newtonian Dynamics (MOND). By adjusting the stellar mass-to-light ratio, dark matter models can match simultaneously both the rotation curve and bar-stability requirements in these galaxies. To be consistent with stability constraints, in two of these galaxies, the stellar mass-to-light ratio is a factor of ~1.5-2 lower than the values suggested from galaxy colours. In contrast, MOND fits to the rotation curves are poor in three galaxies, perhaps because the gas tracer contains noncircular motions. The bar stability analysis provides a new observational test to MOND. We find that most of the galaxies under study require abnormally-high levels of random stellar motions to be bar stable in MOND. In particular, for the only galaxy in the sample for which the line-of-sight stellar velocity dispersion has been measured (NGC 6503), the observed velocity dispersion is not consistent with MOND predictions because it is far below the required value to guarantee bar stability. Precise measurements of mass-weighted velocity dispersions in (unbarred and bulgeless) spiral galaxies are crucial to test the consistency of MOND.

description: A longstanding conjecture of Erdős and Simonovits states that for every rational $r$ between $1$ and $2$ there is a graph $H$ such that the largest number of edges in an $H$-free graph on $n$ vertices is $Θ(n^r)$. Answering a question raised by Jiang, Jiang and Ma, we show that the conjecture holds for all rationals of the form $2 - a/b$ with $b$ sufficiently large in terms of $a$.

The first report of the iranian combination of tetralogy of fallot and hypertrophic cardiomyopathy, A rare case report
Publisher: name: Birjand University of Medical Sciences
Year: 2022

description: The Tetralogy of Fallot is the most common cyanotic congenital heart disease that is often associated with chromosomal aberration had a high prevalence rate of all congenital heart diseases. The association of the Tetralogy of Fallot (ToF) with other congenital cardiac defects, especially with hypertrophic cardiomyopathy, is infrequent. While, unlike the tetralogy of Fallot, hypertrophic cardiomyopathy is accompanied by specific gene loci.\nWe report this scarce association in a 6-month male infant, cyanotic since birth and known with ToF, in her first hospital admission for treatment of recurring cyanotic crises. After the preliminary evaluations and the unsuccessful stenting of the patent ductus arteriousus (PDA) under an angiographic manner, he was prepared to undergo cardiac surgery to establish a modified Blalock-Taussig Shunt procedure. The patient was discharged in good condition and suggested that his parents follow up on his cardiac function after it. On follow-up at the age of three, the child had no cyanotic crises in this period.

description: The coalescence of a neutron star with a black hole is a primary science target of ground-based gravitational wave detectors. Constraining or measuring the neutron star spin directly from gravitational wave observations requires knowledge of the dependence of the emission properties of these systems on the neutron star spin. This paper lays foundations for this task, by developing a numerical method to construct initial data for black hole--neutron star binaries with arbitrary spin on the neutron star. We demonstrate the robustness of the code by constructing initial-data sets in large regions of the parameter space. In addition to varying the neutron star spin-magnitude and spin-direction, we also explore neutron star compactness, mass-ratio, black hole spin, and black hole spin-direction. Specifically, we are able to construct initial data sets with neutron stars spinning near centrifugal break-up, and with black hole spins as large as $S_{\rm BH}/M_{\rm BH}^2=0.99$.

description: The Eifel – Wuppertal-Elberfeld – Mainz Connections of the Archaeologist Adolf Schulten and the Painter Curtius Schulten. A Newly Attributed Painting in Mainz of the Celtiberian and Roman Site of Numantia, Spain While this author was working on an English translation of Adolf Schulten’s book »Die Stadt Numantia« (Munich 1931) about Schulten’s 1905 excavations at the Celtiberian and Roman city of Numantia, he unexpectedly encountered a footnote mentioning the artist Curtius Schulten producing a painting of Numantia, owned by Adolf Schulten. The subsequent research led to the identification of a previously unrecognised oil painting by this well-known twentieth-century German, mainly Eifel-based artist. Ironically, it had long been on public display in the Römisch-Germanisches Zentralmuseum (RGZM; since 2023: Leibniz-Zentrum für Archäologie [LEIZA]), Mainz. The assistance of the painter’s son, Marius Schulten, also led to the revelation of surviving, and in several cases unpublished, engravings and photographs from Curtius Schulten’s 1925 Numantia visit. These include local people whom Adolf Schulten would have known and employed on his excavations, as well as an unpublished and undated photograph of Numantia by Adolf Schulten. The painting’s commission, purpose and context, with reference to some other near-contemporary Numantia artwork, the painting itself and a discussion of some of the associated images created by Curtius Schulten are presented here.

Hiccups as a rare presentation of pulmonary embolism: A case report study
Publisher: name: Birjand University of Medical Sciences
Year: 2022

description: Pulmonary Embolism (PE) causes more than 300,000 deaths per year in the United States. Early diagnosis and treatment can significantly reduce mortality. Hiccups are involuntary spasmodic contractions in the respiratory muscles (inspiratory muscles), especially the diaphragm. Due to the importance of early diagnosis and quick treatment of PE, knowing its uncommon symptoms can help to diagnose and treat it before death. A 67-year-old man with no history of previous diseases and a history of knee joint surgery (5 years ago) came to the emergency room (ER) with continuous hiccups since 10 days ago. There were no cardiovascular risk factors such as family history, history of stroke and thromboembolism, smoking, alcohol, diabetes mellitus and hypertension. Respiratory rate (RR) was 18 breaths/minute, pulse rate (PR) was 120 beats/minute, blood pressure (BP) was 122/84 mmHg, oxygen saturation (SPO2) in the room was 96%, and body temperature (T) was 36 °C. He was a candidate for computed tomography angiography (CTA). The filling defect was observed in the distal peripheral of the left main pulmonary artery (LMPA), with extension to the left upper lobe (LUL), left lower lobe (LLL), and segmental branches. After 6 days of hospitalization, with the improvement of symptoms and stability of vital signs, he was discharged with medications. Due to the association of hiccups with dangerous diseases, it is important to investigate continuous and long hiccups.

description: Lateinische Inschriften auf merowingerzeitlichen Keramikgefäßen. Studien zum Schriftgebrauch im Merowingerreich Im Raum nördlich und nordöstlich von Paris wurden zwischen ca. 530 und 630 Keramikgefäße mittels Rollrädchen mit Inschriften verziert. Diese Verzierungstechnik erlaubt die gleichartige Dekoration großer Serien von Gefäßen, sodass von einem weit umfangreicheren Auftreten »beschrifteter« Knickwandbecher auszugehen ist. Die kurzen Inschriften nennen christliche Inhalte ebenso wie Namen von Herstellern bzw. Auftraggebern. Zumeist sind die Buchstaben durch gleicharmige Kreuze eingefasst. Der Raum, in dem sie auftreten, ist im 6. Jahrhundert nur relativ locker in kirchliche Strukturen eingebunden. Wir vermuten, dass mit den Gefäßen mit Inschriften an spätantike Praktiken angeknüpft und die Becher zur Verbreitung und Vergegenwärtigung des neuen gemeinsamen religiösen Überbaus genutzt wurden. Die wenigen merowingerzeitlichen Gefäße mit individuellen, eingeritzten Graffiti stellen als Nachahmungen die Wertschätzung der eventuell bei Festen verteilten Exemplare mit Rollrädchenverzierung heraus.

description: Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark discovery, potentially providing a significant clue to some of our most basic, big-picture scientific questions about the Universe. In this white paper, we survey the leading early-Universe mechanisms that may produce a detectable signal -- including inflation, phase transitions, topological defects, as well as primordial black holes -- and highlight the connections to fundamental physics. We review the complementarity with collider searches for new physics, and multimessenger probes of the large-scale structure of the Universe.

New Late Hallstatt Complex of Metal Ware from Panivtsi, Western Podolia / UA

description: A New Late Hallstatt Complex of Metal Ware from Panivtsi, Western Podolia / UA. Preliminary Report A new complex of metal objects was discovered at the end of 2014 during cultivation work near Panivtsi in the Ternopil oblast in Ukraine. The authors could document that the bottom of a large upside down bronze bucket was first unearthed; the situla covered two bronze cauldrons, which had been placed one on top of the other. The vessels had been placed in a shallow pit approximately 1 m in diameter, at a depth of 0.45–0.50 m below the surface. The latest bronze situlas of the Panivtsi type occur only until the first half of the 8th century BCE. The deposit of the West Podolian group presented here demonstrates the coexistence of metal imports from the eastern Alpine region and Upper Italy with metal products of strictly local manufacture (cauldrons, etc.) in closed complexes. How could such »early« vessels and, certainly, »late« cauldrons coexist in one complex? Until recently, it was accepted that the use of similar vessels (of the »Scythian« type) within modern Ukraine began only in the 5th century BCE. However, after the discovery in Shvaikivtsi, where a similarly shaped cauldron from the third quarter of the 8th century BCE was found, and now in Panivtsi as well, the dating of the initial use of this type of cast vessels in the area investigated moves back at least one and a half centuries. After the discovery of the two deformed cauldrons in Panivtsi, the function of the vessels has become clearer. Apparently, the role of the cauldron in the ritual actions could have been twofold: either it could have been manipulated to ensure military fortune and divine help; or the burial of the vessels could have been connected with the death of an eminent dignitary or dynast of the time. In summary, the earliest finds of bronze cast cauldrons within modern Ukraine were made in Western Podolia (Shvaikivtsi, Panivtsi). By the example of the complexes of cauldrons we see that the connections between the Middle Dniester region (including West Podolia) and cultures of the Adriatic coast, the East-Alpine area and Upper Italy, which were established in the beginning of the Ha B3 period, did not cease in the following period and still existed in the 7th century BCE.

description: Background: As improving code review (CR) effectiveness is a priority for many software development organizations, projects have deployed CR analytics platforms to identify potential improvement areas. The number of issues identified, which is a crucial metric to measure CR effectiveness, can be misleading if all issues are placed in the same bin. Therefore, a finer-grained classification of issues identified during CRs can provide actionable insights to improve CR effectiveness. Although a recent work by Fregnan et al. proposed automated models to classify CR-induced changes, we have noticed two potential improvement areas -- i) classifying comments that do not induce changes and ii) using deep neural networks (DNN) in conjunction with code context to improve performances. Aims: This study aims to develop an automated CR comment classifier that leverages DNN models to achieve a more reliable performance than Fregnan et al. Method: Using a manually labeled dataset of 1,828 CR comments, we trained and evaluated supervised learning-based DNN models leveraging code context, comment text, and a set of code metrics to classify CR comments into one of the five high-level categories proposed by Turzo and Bosu. Results: Based on our 10-fold cross-validation-based evaluations of multiple combinations of tokenization approaches, we found a model using CodeBERT achieving the best accuracy of 59.3%. Our approach outperforms Fregnan et al.'s approach by achieving 18.7% higher accuracy. Conclusion: Besides facilitating improved CR analytics, our proposed model can be useful for developers in prioritizing code review feedback and selecting reviewers.

description: Chronology of the Mesolithic Ihren 8 Site (Central Ukraine) The paper proposes a more precise chronology for the Mesolithic assemblages of the Ihren 8 site, Dnipro region, Central Ukraine. It is based on a critical revision of the 33 available radiocarbon dates and the presentation of two new AMS dates carried out on animal bones. The data indicate that there are at least four temporal Mesolithic horizons on the site of Ihren 8: three related to 8200–7600 calBCE and one significantly later event (post-6650 cal BCE). The assemblages with regular blades are thus notably earlier than usual in the Late Mesolithic here, so that one can postulate a Middle Mesolithic period in the South Ukraine.

Analytical solutions of the Arrhenius-Semenov problem for constant volume burn

Year: 2023
Subjects: subject: Chemical Physics (physics.chem-ph)

description: Analytical solutions to the Semenov thermal ignition problem for constant volume burn governed by Arrhenius reaction kinetics are derived. Specifically, an approximate analytical solution technique for the Arrhenius-Semenov differential equation is derived for reaction orders $n \in \mathbb{R}_{>0}$ and exact solutions are also constructed for reaction orders $n \in \mathbb{N}: n \leq 3$. The approximation technique relies on expansion of the respective nondominant terms in the differential equation at the lower and upper bounds of the reaction progress variable in order to create a pair of integrable series. The two integrated series are then connected to create a single continuous analytical solution. Excellent agreement is observed between the analytical approximation and solutions obtained numerically. The presented approximation constitutes a simple and robust strategy for solving the Arrhenius-Semenov problem analytically.

description: Auf dem Weg von oder nach Hallstatt? Neue Forschungen zur Rolle der hallstattzeitlichen Seeufersiedlung in Traunkirchen (Bez. Gmunden / AT) Auf einer Halbinsel des Traunsees befindet sich die einzige bekannte Seeufersiedlung der Hallstattzeit in Österreich. Aufgrund der verkehrsgeografischen Lage sowie von Grab- und Siedlungsfunden wird seit Langem eine Funktion im Handel mit dem Salz aus der Saline von Hallstatt vermutet, die sich rund 33 km südlich von Traunkirchen befindet. Mittels minimalinvasiver Prospektionen unter Wasser und an Land gelang es in den Jahren 2020 und 2021, die Ausdehnung und Mächtigkeit der ältereisenzeitlichen Siedlungsschichten in Traunkirchen und ihre exakte Datierung zu klären. Durch die Bohrungen lässt sich eine ehemalige Bucht des Traunsees nachweisen, die einen idealen natürlichen Hafen an der Spitze der exponierten Halbinsel bot. Aufgrund der neuen Prospektionsergebnisse und umfangreicher Recherchen zeichnet sich ab, dass Traunkirchen seine Bedeutung während der Hallstattzeit nicht primär als Umschlagplatz im Salztransport, sondern vielmehr als Ausgangspunkt für die Versorgung der Saline mit Lebensmitteln und als Basis für die Lastenträger, Säumer oder Bootsleute erlangte.

description: It is generally acknowledged that a hanging cantilevered pipe conveying fluid becomes unstable by flutter-type instability at a critical flow velocity; moreover, the pipe undergoes periodic self-excited oscillations in the post-flutter region. Additionally, the critical flow velocity increases when the magnetized pipe is exposed to an actuating parallel magnetic field. The question arises as to whether the actuating magnetic field leads to lessening the oscillation amplitude of the system in the post-flutter region. To answer the question, the nonlinear responses of a fluid-conveying cantilevered hard magnetic soft pipe with uniform and nonuniform magnetizations under an actuating parallel magnetic field are examined. In the case of the nonuniform magnetization, the mass density and elastic modulus of the pipe in addition to its residual magnetic flux density vary along its length. The mathematical formulation is constructed via a nonlinear geometrically exact model and is solved by employing the Galerkin technique in conjunction with the Runge-Kutta finite difference scheme. The numerical results are then analyzed to reveal the role of magnetization in the magneto-hydro-elastic responses of the system in the absence and presence of magnetic field.

description: Success and efficiency of software and system design fundamentally relies on its models. The more they are based on formal methods the more they can be automatically transformed to execution models and finally to implementation code. This paper presents model transformation and model integration as specific problem within bidirectional model transformation, which has shown to support various purposes, such as analysis, optimization, and code generation. The main purpose of model integration is to establish correspondence between various models, especially between source and target models. From the analysis point of view, model integration supports correctness checks of syntactical dependencies between different views and models. The overall concept is based on the algebraic approach to triple graph grammars, which are widely used for model transformation. The main result shows the close relationship between model transformation and model integration. For each model transformation sequence there is a unique model integration sequence and vice versa. This is demonstrated by a quasi-standard example for model transformation between class models and relational data base models.

description: The design and optimization of wireless networks have mostly been based on strong mathematical and theoretical modeling. Nonetheless, as novel applications emerge in the era of 5G and beyond, unprecedented levels of complexity will be encountered in the design and optimization of the network. As a result, the use of Artificial Intelligence (AI) is envisioned for wireless network design and optimization due to the flexibility and adaptability it offers in solving extremely complex problems in real-time. One of the main future applications of AI is enabling user-level personalization for numerous use cases. AI will revolutionize the way we interact with computers in which computers will be able to sense commands and emotions from humans in a non-intrusive manner, making the entire process transparent to users. By leveraging this capability, and accelerated by the advances in computing technologies, wireless networks can be redesigned to enable the personalization of network services to the user level in real-time. While current wireless networks are being optimized to achieve a predefined set of quality requirements, the personalization technology advocated in this article is supported by an intelligent big data-driven layer designed to micro-manage the scarce network resources. This layer provides the intelligence required to decide the necessary service quality that achieves the target satisfaction level for each user. Due to its dynamic and flexible design, personalized networks are expected to achieve unprecedented improvements in optimizing two contradicting objectives in wireless networks: saving resources and improving user satisfaction levels.

description: In several rule-based applications using graph transformation as underlying modeling technique the following questions arise: How can one be sure that a specific sequence of rules is applicable (resp. not applicable) on a given graph? Of course, it is possible to use a trial and error strategy to find out the answer to these questions. In this paper however, we will formulate suitable sufficient criteria for applicability and other ones for non-applicability. These criteria can be checked in a static way i.e. without trying to apply the whole rule sequence explicitly. Moreover if a certain criterion is not satisfied, then this is an indication for reasons why rule sequences may or may not be applicable. Consequently it is easier to rephrase critical rule sequences. The results are formulated within the framework of double pushout (DPO) graph transformations with negative application conditions (NACs).

We show that inter-band excitations in semimetals are generally comprised of both excitons and antiparticles of excitons. These two stand for two distinct inter-band collective modes in semimetals, having different energies and opposite conserved charges. The conserved charge here is a quantity conjugate to a joint U(1) symmetry of two electron's bands associated with the inter-band excitations. The opposite charges foster fertile scattering processes among the inter-band collective modes. In spin-polarized systems, they also suggest possible experimental detections of the antiparticles. We clarify that the effective theory of the inter-band excitations is given by a generalized Klein-Gordon theory. Our theory provides a comprehensive understanding of excitonic spectra in generic semimetals, bringing a new insight into electronic collective phenomena in solids.

description: Magic states are the resource that allows quantum computers to attain an advantage over classical computers. This resource consists in the deviation from a property called stabilizerness which in turn implies that stabilizer circuits can be efficiently simulated on a classical computer. Without magic, no quantum computer can do anything that a classical computer cannot do. Given the importance of magic for quantum computation, it would be useful to have a method for measuring the amount of magic in a quantum state. In this work, we propose and experimentally demonstrate a protocol for measuring magic based on randomized measurements. Our experiments are carried out on two IBM Quantum Falcon processors. This protocol can provide a characterization of the effectiveness of a quantum hardware in producing states that cannot be effectively simulated on a classical computer. We show how from these measurements one can construct realistic noise models affecting the hardware.

Alignment

description: Due to the remarkable optoelectronic properties, two-dimensional molybdenum disulfide (MoS2) exhibits great potential for photonic applications. However, to utilize its full potential it is imperative to have a homogenous and controlled distribution of MoS2 nanosheets within a polymer matrix which is a major problem experienced during fabrication of polymer nanocomposites. Moreover, methods for aligning nanosheets in polymer composites have received considerable interest due to physical properties of such composites being significantly enhanced but such methods are rarely reported. Here we show a novel, simple and scalable method to align MoS2 nanosheets within wet-spun poly(vinyl alcohol) (PVA) fibers. This was achieved by drawing single filament hydrated fibers containing MoS2 under uniaxial strain. Highly drawn (>200% strain) fibers comprise of large microfibrils running along the length of the fibers that are in turn comprised of smaller perpendicular striations. Atomic force microscopy revealed that MoS2 flakes are preferentially embedded between the smallest of these fibrils formed as a result of a secondary crystallization upon drawing while Raman spectroscopy confirmed high degree of anisotropy of MoS2 within the fibers. This method can be generalized and also used to align other 2D nanomaterials including graphene, transition metal dichalcogenides and black phosphorus monolayers among others for a range of optoelectronic applications such as polarization-dependent saturable absorbers.

The aim is to provide a relatively nontechnical introduction to the underlying ideas, emphasizing the connection between the two areas. We also indicate how operator-valued $(L^{p},L^{q})$ Fourier multipliers can be applied to functional calculus theory.

description: Wer oder was war und ist ein ‚Gastarbeiter‘? Eigentlich scheint sich der Begriff ganz eindeutig auf diejenigen Arbeitsmigrant:innen zu beziehen, die zwischen 1955 und 1973 über die bilateralen Anwerbeabkommen aus den ‚Anwerbeländern‘ in die Bundesrepublik migrierten. Im Bild des ‚Gastes‘ war die Erwartungshaltung einer Rückkehr verankert, ein dauerhafter Verbleib war politisch nicht vorgesehen. Der folgende Beitrag argumentiert, dass der Begriff ‚Gastarbeiter‘ trotz seiner scheinbaren Eindeutigkeit in Geschichte und Gegenwart vielfältig, asynchron und ambivalent verwendet wurde und wird. In seinen Entwicklungslinien bewegt sich der Wortgebrauch zwischen beschönigender Adaption, rassistischer Projektionsfläche und indifferentem Sammelbegriff. Zur Uneindeutigkeit und Langlebigkeit des Begriffs trug maßgeblich seine alltägliche gesellschaftliche Verwendung bei. Das Wort wurde ‚von unten‘ geprägt und erhielt erst dadurch Einzug in den politischen Diskurs. Der ‚Gastarbeiter‘ ist keinesfalls eine Wortschöpfung der politischen Amtssprache der Arbeitsmigration. Speziell in den noch jungen 2020er Jahren wird der Begriff erneut auf vielfältige Weise umgedeutet.

description: In this paper we construct a new factorized representation of the $R$-matrix related to the affine algebra $U_{q}(\widehat{sl_{n}})$ for symmetric tensor representations with arbitrary weights. Using the 3D approach we obtain explicit formulas for the matrix elements of the $R$-matrix and give a simple proof that a "twisted" $R$-matrix is stochastic. We also discuss symmetries of the $R$-matrix, its degenerations and compare our formulas with other results available in the literature.

description: A subset $M$ of a continuum $X$ is called a \textit{meager composant} if $M$ is maximal with respect to the property that every two of its points are contained in a nowhere dense subcontinuum of $X$. Motivated by questions of Bellamy, Mouron and Ordoñez, we show that no tree-like continuum has a proper open meager composant, and that every tree-like continuum has either $1$ or $2^{\aleph_0}$ meager composants. We also prove a decomposition theorem: If $X$ is tree-like and every indecomposable subcontinuum of $X$ is nowhere dense, then the partition of $X$ into meager composants is upper semi-continuous and the space of meager composants is a dendrite.

description: We construct spectral zeta functions for the Dirac operator on metric graphs. We start with the case of a rose graph, a graph with a single vertex where every edge is a loop. The technique is then developed to cover any finite graph with general energy independent matching conditions at the vertices. The regularized spectral determinant of the Dirac operator is also obtained as the derivative of the zeta function at a special value. In each case the zeta function is formulated using a contour integral method, which extends results obtained for Laplace and Schrodinger operators on graphs.

description: Which patients may benefit more from immune checkpoint inhibitors (ICIs) is still an important question. The present study aimed to investigate the role of the PD-L1 molecule in predicting the effectiveness of PD-1/PD-L1 inhibitors in gastric cancer patients. We searched PubMed, Scopus, Web of Science, and EMBASE databases as of 25 March 202225 March 2022. Ten articles were included. When we used the TPS method for PD-L1 expression, none of the patients in tumor proportion score (TPS)≥1% and TPS < 1% groups took advantage of ICI therapy in terms of OS and PFS. However, gastric cancer patients with combined-positive score (CPS)≥1, CPS ≥ 5, and CPS ≥ 10 tumors represented superior OS for ICIs over the control agents, while their counterparts (i.e. patients with CPS < 1, CPS < 5, and CPS < 10 tumors) did not. In the subgroup analysis when patients with CPS ≥ 1 were selected, Nivolumab improved the OS and PFS remarkably by 26% and 25% when compared with control agents, respectively. However, Pembrolizumab significantly increased the rate of disease progression by 47% relative to the control medications. Among patients suffering from gastric cancer, considering PD-L1 CPS thresholds seems to be a more reliable predictive factor than TPS threshold for lower rate of mortality when PD-1/PD-L1 inhibitors are administered.
