description: A high energy muon collider can provide new and complementary discovery potential to the LHC or future hadron colliders. Leptoquarks are a motivated class of exotic new physics models, with distinct production channels at hadron and lepton machines. We study a vector leptoquark model at a muon collider with $\sqrt{s} = 3, 14$ TeV within a set of both UV and phenomenologically motivated flavor scenarios. We compute which production mechanism has the greatest reach for various values of the leptoquark mass and the coupling between leptoquark and Standard Model fermions. We find that we can probe leptoquark masses up to an order of magnitude beyond $\sqrt{s}$ with perturbative couplings. Additionally, we can also probe regions of parameter space unavailable to flavor experiments. In particular, all of the parameter space of interest to explain recent low-energy anomalies in B meson decays would be covered even by a $\sqrt{s} = 3$ TeV collider.

Charadra dispulsa

description: Charadra dispulsa Morrison Figs 16, 29, 34 Charadra dispulsa Morrison, 1875: 214. Type material. Type locality: [USA:] “ Waco, Texas.” Holotype female. MCZ; photograph examined, available at http://insects.oeb.harvard.edu/ MCZ /. Diagnosis. A relatively small, pale silvery-grey species with few forewing markings that are largely confined to a narrow, black antemedial line and a prominent partial medial band from the costa to mid wing. Th e small size, pale colour, reduced markings, lack of central orbicular black scales, and black medial dash connecting the AM and PM lines allow this species to easily be distinguished. Distribution and biology. Occurs from Texas southward and westward to at least San Luis Potosi, Mexico. Collection records range from March through May and July for southern Texas. Nothing is known of the larval stages or food plants, but larvae are possibly oak feeders. Remarks. Barcode sequence for one specimen of C. dispulsa was available, which differed about 3.5% from C. deridens, 4% from C. moneta, and 6% from C. franclemonti.

description: We reveal the existence of systematic variations of isobaric fragility in different supercooled Lennard-Jones binary mixtures by performing molecular dynamics simulations. The connection between fragility and local structures in the bulk is analyzed by means of a Voronoi construction. We find that clusters of particles belonging to locally preferred structures form slow, long-lived domains, whose spatial extension increases by decreasing temperature. As a general rule, a more rapid growth, upon supercooling, of such domains is associated to a more pronounced super-Arrhenius behavior, hence to a larger fragility.

description: We empirically study the genealogical trees of ten families for about five centuries in Korea. Although each family tree contains only the paternal part, the family names of women married to the family have been recorded, which allows us to estimate roughly the family name distributions for the past five hundred years. Revealed is the fact that the unique Korean family name distribution, characterized by a logarithmic form of the cumulative distribution and an exponentially decaying rank-size plot often called the Zipf plot, has remained unchanged for a long time. We discuss the implications of our results within a recently suggested theoretical model and compare them with observations in other countries in which power-law forms are abundantly found.

The Principle of Relativity and Inertial Dragging

description: Machs principle and the principle of relativity have been discussed by H. I. Hartman and C. Nissim-Sabat in this journal. Several phenomena were said to violate the principle of relativity as applied to rotating motion. These claims have recently been contested. However, in neither of these articles have the general relativistic phenomenon of inertial dragging been invoked, and no calculation have been offered by either side to substantiate their claims. Here I discuss the possible validity of the principle of relativity for rotating motion within the context of the general theory of relativity, and point out the significance of inertial dragging in this connection. Although my main points are of a qualitative nature, I also provide the necessary calculations to demonstrate how these points come out as consequences of the general theory of relativity

title: Behind the thin black line: Leslie Illingworth and the political cartoonist in wartime
Creators: name: Bryant, Mark
Publisher: name: University of Kent
Year: 2002

description: W. H. Russell, the famous war correspondent of The Times. created the phrase 'The Thin Red Line' to describe the brave stand of British troops against the Russians during the Crimean War. It is the intention of this thesis to explore the work of the political cartoonist in wartime using the example of one particular artist, Leslie Illingworth of the Daily Mail during the Second World War. This is a relatively new area of research and the main aim of the thesis is to discover what it is that a staff political cartoonist working for a national daily newspaper actually does in wartime. In addition, it investigates what sort of person such an artist is, what his relationship is to his newspaper, his public and the government of the day, and how far his material follows in the historical traditions of political cartoon art. The thesis draws on extensive archive material - including a large uncatalogued collection of wartime cartoons by Illingworth deposited in the National Library of Wales in Aberystwyth - and considerable original research into the hitherto unrecorded life of the artist himself. After tracing the history of war cartoons in general, the history of the Daily Mail and the background of Illingworth's own life and career, a detailed study is made of Illingworth's wartime political cartoons - their content, frequency of publication and other factors - before examining his work in the context of his wartime contemporaries and evaluating the impact of his cartoons on the readers of the Daily Mail and the world at large. The thesis concludes that, during the Second World War in particular, political cartoonists had a far from simple job and were important figures who were greatly valued by the newspapers for which they worked, by the public at large and by the government of the day. Their creations were seen by Britain and her allies - as well as her enemies - as a significant weapon in the arsenal of democracy. Also, as the Second World War was the last major international conflict before the widespread use of television, it is argued that this period marked the high point in the development of political war cartoons in daily newspapers throughout history. In addition, by demonstrating that Leslie Illingworth of the Daily Mail can be seen not only as a typical political cartoonist working as a staff artist on a typical national daily newspaper during this period, but also one of its most accomplished practitioners, a case is made for viewing him as one of the finest political war cartoonists of all time.

description: The generation of large-scale magnetic fields ($\overline{\mathbf{B}}$) in astrophysical systems is driven by the mean turbulent electromotive force ($\overline{\cal E}$), the cross correlation between local fluctuations of velocity and magnetic fields. This can depend non-locally on $\overline{\mathbf{B}}$ through a convolution kernel $K_{ij}$. In a new approach to find $K_{ij}$, we directly fit the time series data of $\overline{\cal E}$ versus $\overline{\mathbf{B}}$ from a galactic dynamo simulation using singular value decomposition. We calculate the usual turbulent transport coefficients as moments of $K_{ij}$, show the importance of including non-locality over eddy length scales to fully capture their amplitudes and that higher order corrections to the standard transport coefficients are small in the present case.

description: It was recently pointed out that very energetic subclasses of supernovae (SNe), like hypernovae and superluminous SNe, might host ultra-strong magnetic fields in their core. Such fields may catalyze the production of feebly interacting particles, changing the predicted emission rates. Here we consider the case of axion-like particles (ALPs) and show that the predicted large scale magnetic fields in the core contribute significantly to the ALP production, via a coherent conversion of thermal photons. Using recent state-of-the-art SN simulations including magnetohydrodynamics, we find that if ALPs have masses $m_a \sim {\mathcal O}(10)\, \rm MeV$, their emissivity via magnetic conversions is over two orders of magnitude larger than previously estimated. Moreover, the radiative decay of these massive ALPs would lead to a peculiar delay in the arrival times of the daughter photons. Therefore, high-statistics gamma-ray satellites can potentially discover MeV ALPs in an unprobed region of the parameter space and shed light on the magnetohydrodinamical nature of the SN explosion.

We consider various cases with different target nuclei and energies systematically and find the clear signals in the theoretical spectra for all cases considered in this article. The signals show very interesting structures, such as the $RESONANCE DIP$ instead of the resonance peak. We discuss the origins of the interesting structures and possibilities to get new information on the existence of the kaonic nuclei from the spectra of the atomic state formations.

A Photoionization Model For The Soft X-Ray Spectrum Of NGC 4151

description: We present analysis of archival data from multiple XMM-Newton observations of the Seyfert 1 galaxy NGC 4151. Spectral data from the RGS instruments reveal several strong soft X-ray emission lines, chiefly from hydrogen-like and helium-like oxygen, nitrogen, neon and carbon. Radiative recombination continua (RRC) from oxygen and carbon are also detected. Our analysis suggests that the emission data are consistent with photoionization. Using the CLOUDY photoionization code, we found that, while a two-component, high column density model (10e23 cm-2) with low covering factor proved adequate in reproducing all detected Lyman series lines, it proved insufficient in modeling He-like triplets observed (neon, oxygen, and nitrogen). If resonance line data were ignored, the two-component model was sufficient to match flux from intercombination and forbidden lines. However, with the inclusion of resonance line data, He-like triplets could no longer be modeled with only two components. We found that observed oxygen G and R ratios especially were anomalous in parameter space investigated. We investigated, and were forced to dismiss, the possibility that a third purely collisional component could be responsible for enhanced resonance line contributions. We succeeded in modeling the observed spectrum with the addition of a third, lower column density (10e20.5 cm-2) component with non-zero microturbulence and high covering factor. While sufficient to reproduce observed soft X-ray flux, our model faces certain shortcomings, particularly in a less-than-ideal visual fit to the line profile. Two of the three emission model components bear similarities to components determined by Kraemer et al. (2005) in their study of NGC 4151 absorption spectra.

description: We report the prediction of quasi-bound states (resonant states with very long lifetimes) that occur in the eigenvalue continuum of propagating states for a wide region of parameter space. These quasi-bound states are generated in a quantum wire with two channels and an adatom, when the energy bands of the two channels overlap. A would-be bound state that lays just below the upper energy band is slightly destabilized by the lower energy band and thereby becomes a resonant state with a very long lifetime (a second QBIC lays above the lower energy band).

description: We present the Herschel Extragalactic Legacy Project (HELP). This project collates, curates, homogenises, and creates derived data products for most of the premium multi-wavelength extragalactic data sets. The sky boundaries for the first data release cover 1270 deg2 defined by the Herschel SPIRE extragalactic survey fields; notably the Herschel Multi-tiered Extragalactic Survey (HerMES) and the Herschel Atlas survey (H-ATLAS). Here, we describe the motivation and principal elements in the design of the project. Guiding principles are transparent or "open" methodologies with care for reproducibility and identification of provenance. A key element of the design focuses around the homogenisation of calibration, meta data and the provision of information required to define the selection of the data for statistical analysis. We apply probabilistic methods that extract information directly from the images at long wavelengths, exploiting the prior information available at shorter wavelengths and providing full posterior distributions rather than maximum likelihood estimates and associated uncertainties as in traditional catalogues. With this project definition paper we provide full access to the first data release of HELP; Data Release 1 (DR1), including a monolithic map of the largest SPIRE extragalactic field at 385 deg2 and 18 million measurements of PACS and SPIRE fluxes. We also provide tools to access and analyse the full HELP database. This new data set includes far-infrared photometry, photometric redshifts, and derived physical properties estimated from modelling the spectral energy distributions.

description: We present a kinematic study of ionised extraplanar gas in two low-inclination late-type galaxies (NGC 3982 and NGC 4152) using integral field spectroscopy data from the DiskMass H$α$ sample. We first isolate the extraplanar gas emission by masking the H$α$ flux from the regularly rotating disc. The extraplanar gas emission is then modelled in the three-dimensional position-velocity domain using a parametric model described by three structural and four kinematic parameters. Best-fit values for the model are determined via a Bayesian MCMC approach. The reliability and accuracy of our modelling method are carefully determined via tests using mock data. We detect ionised extraplanar gas in both galaxies, with scale heights $0.83^{+0.27}_{-0.40}\,\mathrm{kpc}$ (NGC 3982) and $1.87^{+0.43}_{-0.56}\,\mathrm{kpc}$ (NGC 4152) and flux fraction between the extraplanar gas and the regularly rotating gas within the disc of 27% and 15% respectively, consistent with previous determinations in other systems. We find lagging rotation of the ionized extraplanar gas in both galaxies, with vertical rotational gradients $-22.24^{+6.60}_{-13.13} \,\mathrm{km\,s^{-1}\,kpc^{-1}}$ and $-11.18^{+3.49}_{-4.06}\,\mathrm{km\,s^{-1}\,kpc^{-1}}$, respectively, and weak evidence for vertical and radial inflow in both galaxies. The above results are similar to the kinematics of the neutral extraplanar gas found in several galaxies, though this is the first time that 3D kinematic modelling of ionised extraplanar gas has been carried out. Our results are broadly consistent with a galactic fountain origin combined with gas accretion. However, a dynamical model is required to better understand the formation of ionised extraplanar gas.

description: A diagrammatic theory around atomic limit is proposed for normal state of Anderson Impurity Model. The new diagram method is based on the ordinary Wick's theorem for conduction electrons and a generalized Wick's theorem for gtrongly correlated impurity electrons. This last theorem coincides with the definition of Kubo cumulants. For the mean value of the evolution operator a linked cluster theorem is proved and a Dyson's type equations for one-particle propagators are established. The main element of these equations is the correlation function which contains the spin, charge and pairing fluctuations of the system. The thermodynamic potential of the system is expressed through one-particle renormalized Green's functions and the corelation function. The stationary property of the thermodynamic potential is established with respect to the changes of correlation function.

description: We numerically investigated the connection between isobaric fragility and the properties of high-order stationary points of the potential energy surface in different supercooled Lennard-Jones mixtures. The increase of effective activation energies upon supercooling appears to be driven by the increase of average potential energy barriers measured by the energy dependence of the fraction of unstable modes. Such an increase is sharper, the more fragile is the mixture. Correlations between fragility and other properties of high-order stationary points, including the vibrational density of states and the localization features of unstable modes, are also discussed.

description: We review latest progress in gaseous photomultipliers (GPM) combining solid photocathodes and various types of novel electron multipliers. Cascaded gaseous electron multipliers (GEM) coated with CsI photocathodes can efficiently replace UVsensitive wire chambers for single-photon recording in Cherenkov and other detectors. Other hole-multipliers with patterned electrodes (Micro-Hole and Strip Plates) and improved ion-blocking properties are discussed; these permit reducing considerably photon- and ion-induced secondary effects. Photon detectors with other electron-multiplier techniques are briefly described, among them GPMs based on Micromegas, capillary-plates, Thick-GEMs and resistive Thick GEMs. The two latter techniques, robust and economically produced, are particularly suited for large-area GPM applications, e.g. in RICH. Cascaded hole-multipliers with very high ion-blocking performance permitted the development and the first demonstration of DC-operated visible-sensitive gaseous photomultipliers with bialkali photocathodes and single-photon sensitivity. Recent progress is described in GPMs operated at cryogenic temperatures for rare-event noble-liquid detectors and medical imaging.

description: Event Horizon Telescope (EHT) observations of the core of the galaxy M87 suggest an observational appearance dominated by a ring of approximately 40$μ$as in diameter. The thickness of the ring is less certain: imaging efforts constrained it to be less than half the diameter (consistent with an imaging resolution of 20$μ$as), while visibility-domain modeling suggested a variety of fractional widths, including as low as $10\%$ on some days. The fractional width is very interesting as it has the potential to discriminate between different astrophysical scenarios for the source; in fact, the $10$--$20\%$ range is so narrow as to be in tension with theoretical expectations. In the first of a series of papers on the width of the observed ring, we reproduce a subset of EHT visibility-domain modeling results and we explore whether alternative data analysis methods might favor thicker rings. We point out that the closure phase (and closure amplitude) likelihood function is not independent of residual station gain amplitudes, even at high signal-to-noise, and explore two approximations of practical interest: one standard in the field (and employed by the EHT collaboration), and a new one that we propose. Analyzing the public data, we find that the new likelihood approximation prefers somewhat thicker rings, more in line with theoretical expectations. Further analysis is needed, however, to determine which approximation is better for the EHT data.

SIMULATION AND POSSIBILITIES OF ARTISTIC EXPRESSION
Creators: name: Azimbayeva, Nargiza
Publisher: name: Zenodo
Year: 2023

description: This scientific article explores the intersection of simulation technology and artistic expression, investigating the ways in which simulations open up new possibilities for artists to create immersive and interactive experiences. The study delves into the impact of simulation on various art forms, from visual arts to performing arts, and examines the potential implications for the future of artistic creation. Through an interdisciplinary lens, the article aims to shed light on the evolving relationship between technology-driven simulations and the realm of artistic expression. This cross-sectional study investigates the usage of similes in Persian and Uzbek languages, aiming to explore the linguistic and cultural dimensions that shape the metaphorical expressions in these two distinct languages. Similes, as a form of metaphorical language, play a crucial role in conveying abstract concepts and enriching the linguistic landscape of a given culture. By conducting a comparative analysis of similes in Persian and Uzbek, this research seeks to uncover similarities, differences, and cultural nuances in the metaphorical expressions employed by speakers of these languages.

description: The Navier-Stokes equations and magnetohydrodynamics equations are written in terms of poloidal and toroidal potentials in a finite cylinder. This formulation insures that the velocity and magnetic fields are divergence-free by construction, but leads to systems of partial differential equations of higher order, whose boundary conditions are coupled. The influence matrix technique is used to transform these systems into decoupled parabolic and elliptic problems. The magnetic field in the induction equation is matched to that in an exterior vacuum by means of the Dirichlet-to-Neumann mapping, thus eliminating the need to discretize the exterior. The influence matrix is scaled in order to attain an acceptable condition number.

description: В современной экономической литературе на теоретическом уровне рассматривается целый ряд стратегий развития предприятий. Однако стратегия внешнеэкономической деятельности как самостоятельная форма стратегий не рассматривается вообще либо ей не уделяется достаточного внимания. Цель исследования – идентификация стратегий внешнеэкономической деятельности российских предприятий нефтегазовой отрасли, таких как «Газпром», «Лукойл», «Роснефть» и «Сургутнефтегаз», на основании их ежегодных отчетов и рейтингов российских аналитических агентств. Задачи исследования: разработка методики анализа результатов реализации стратегий внешнеэкономической деятельности, а также анализ результатов реализации стратегий внешнеэкономической деятельности указанных нефтегазовых корпораций. В итоге выявлены особенности стратегий внешнеэкономической деятельности предприятий нефтегазового сектора, показаны их траектории в системе координат «товарная позиция – страна».
description: In modern economic literature, several strategies for the development of enterprises are examined at the theoretical level. However, the strategy of foreign economic activity, as an independent form of strategy, is not acknowledged at all, or not enough attention is paid to it. The purpose of the article is to identify strategies for the foreign economic activity of Russian oil and gas companies, such as Gazprom, Lukoil, Rosneft, and Surgutneftegaz, based on their annual reports and ratings of Russian analytical agencies. The objectives of the study are, firstly, the development of a methodology for analyzing the results of strategies for foreign economic activity, and secondly, the analysis of the implementation results of strategies for foreign economic activity of the mentioned oil and gas companies. As a result of the study, the features of the strategies of foreign economic activity of enterprises in the oil and gas sector were revealed. Their trajectories are shown in the “commodity item – country” coordinate system.

description: Synchronized movement of (both unicellular and multicellular) systems can be observed almost everywhere. Understanding of how organisms are regulated to synchronized behavior is one of the challenging issues in the field of collective motion. It is hypothesized that one or a few agents in a group regulate(s) the dynamics of the whole collective, known as leader(s). The identification of the leader (influential) agent(s) is very crucial. This article reviews different mathematical models that represent different types of leadership. We focus on the improvement of the leader-follower classification problem. It was found using a simulation model that the use of interaction domain information significantly improves the leader-follower classification ability using both linear schemes and information-theoretic schemes for quantifying influence. This article also reviews different schemes that can be used to identify the interaction domain using the motion data of agents.

A systems approach to improving patient safety through medical device purchasing
Creators: name: Hinrichs, S
Publisher: name: Apollo - University of Cambridge Repository
Year: 2009
Subjects: healthcare design

description: The purchase of medical devices involves engaging various stakeholders as well as balancing clinical, technical and financial requirements. Failure to consider these requirements can lead to wider consequences in the delivery of care. This study first builds a general knowledge base of current purchasing practice in a sample of NHS Trusts, which confirms the direction and guidance given by policy documents and literature as to the extent of the challenges faced by purchasing stakeholders. This then leads to an analysis to identify inefficiencies in the purchasing process, and how such practice can lead to risks in the delivery of care. These risks range from injury to individuals, impacts to the healthcare delivery service, and financial and litigation risks. Finally, a framework that highlights these potential risks in the life-cycle of medical devices in hospitals is presented. Key policy guidance has encouraged both researchers and implementers of healthcare services to approach patient safety from a systems perspective, acknowledging that medical device errors are not only directly related to device design, but to the design of the healthcare delivery service system in which the device operates. Little evidence exists of successfully applying systems approaches specifically to medical device purchasing practice. Medical device purchasing, because of its implications to patient safety on the one hand, and the uniqueness of the healthcare context, requires a unique approach. By demonstrating the influence of purchasing practice to service delivery and patient care, the thesis made is that taking a holistic systems approach is one method to improve device purchasing practice, and hence influence better care.

Exact Solution of a Yang-Baxter Spin-1/2 Chain Model and Quantum Entanglement

description: Entanglement is believed to be crucial in macroscopic physical systems for understanding the collective quantum phenomena such as quantum phase transitions. We start from and solve exactly a novel Yang-Baxter spin-1/2 chain model with inhomogeneous and anisotropic short-range interactions. For the ground state, we show the behavior of neighboring entanglement in the parameter space and find that the inhomogeneous coupling strengths affect entanglement in a distinctive way from the homogeneous case, but this would not affect the coincidence between entanglement and quantum criticality.

description: Die Strafverfolgungsstatistik erfasst die im Laufe eines Jahres auf Grund gerichtlicher Entscheidungen rechtskräftig abgeurteilten und verurteilten Personen. Von den Strafvollstreckungsbehörden (Staatsanwaltschaften) werden die Daten von Personen, die sich wegen Verbrechen oder Vergehen nach dem Strafgesetzbuch, nach anderen Bundesgesetzen oder nach Landesrecht einschließlich der Straftaten im Straßenverkehr und Staatsschutzdelikten vor Gericht verantworten mussten, in anonymisierter Form an das Statistische Landesamt übermittelt. Ordnungswidrigkeiten, auch wenn sie in die Zuständigkeit der Strafgerichte fallen, werden durch diese Statistik nicht erfasst. Unterschieden wird dabei in Abgeurteilte und Verurteilte nach allgemeinem Strafrecht und nach Jugendstrafrecht einschließlich nach ehemaligem DDR - Strafrecht. In Thüringen wurde diese Statistik mit Wirkung vom 1. Oktober 1996 erstmals erhoben. In Erwartung des in Vorbereitung befindlichen Rechtspflegestatistikgesetzes war diese Statistik zunächst nicht eingeführt worden. Da die entsprechenden statistischen Informationen auch in Thüringen benötigt werden, erfolgte die Einführung schließlich auf der Grundlage des § 6 des Thüringer Statistikgesetzes. Erste Veröffentlichungen dazu erfolgten im Dezember 1998 für das Berichtsjahr 1997. Im vorliegenden Bericht werden diese Ergebnisse für das Jahr 2004 dokumentiert, weitere Veröffentlichungen erscheinen als Eckzahlen in einem Vorabbericht im Juli sowie in dieser Form im Dezember eines jeden Jahres.

description: In this article, we get classification theorems for a Ricci soliton on the pseudo-Riemannian hypersurface of the Minkowski space $\mathbb{E}^4_1$ taking the potential vector field as the tangent component of the position vector of the pseudo-Riemannian hypersurface, denoted by $(M,g,{\bf x}^T,λ)$ in both Riemannian and Lorentzian settings. First, we obtain the necessary and sufficient condition that a pseudo-Riemannian hypersurface $(M,g)$ in $\mathbb{E}^4_1$ admits a Ricci soliton $(M,g,{\bf x}^T,λ)$. In each of the form of the shape operator of a pseudo-Riemannian hypersurface, we obtain characterization a Ricci soliton on a pseudo-Riemannian hypersurface. More precisely, we show that totally umbilical hypersurfaces, hyperbolic and a pseudo-spherical cylinder in $\mathbb{E}^4_1$ is a shrinking Ricci soliton whose the potential vector field is the tangent part of the position vector. Furthermore, we conclude that there exists only a shrinking Ricci soliton on a Lorentzian isoparametric hypersurface in $\mathbb{E}^4_1$ with nondiagonalizable shape operator whose the minimal polynomial has double real roots.
