description: NASA's New Horizons spacecraft will conduct a close flyby of the cold classical Kuiper Belt Object (KBO) designated (486958) 2014 MU69 on January 1, 2019. At a heliocentric distance of 44 AU, "MU69" will be the most distant object ever visited by a spacecraft. To enable this flyby, we have developed an extremely high precision orbit fitting and uncertainty processing pipeline, making maximal use of the Hubble Space Telescope's Wide Field Camera 3 (WFC3) and pre-release versions of the ESA Gaia Data Release 2 (DR2) catalog. This pipeline also enabled successful predictions of a stellar occultation by MU69 in July 2017. We describe how we process the WFC3 images to match the Gaia DR2 catalog, extract positional uncertainties for this extremely faint target (typically 140 photons per WFC3 exposure), and translate those uncertainties into probability distribution functions for MU69 at any given time. We also describe how we use these uncertainties to guide New Horizons, plan stellar occultions of MU69, and derive MU69's orbital evolution and long-term stability.

description: The rapidly evolving field of catalysis research generates a vast spectrum of data, necessitating innovative approaches to data management, interoperability, and utilization. This White Paper, “Ontology Mapping and Interoperability: Insights from Catalysis Research Data,” emerges from comprehensive discussions and expert contributions during the dedicated workshop in November 2023 hosted by NFDI4Cat. It encapsulates collective insights aimed at harnessing the power and applicability of ontologies and related tools to navigate the complex landscape of catalysis and catalysis related research data and the method transfer to other domains. Together with scientific, domain-specific vocabulary and standard metadata, knowledge graphs can be generated allowing to handle and store data in a structured and FAIR manner (Findable, Accessible, Interoperable, Reusable). This does not only enable consistent data handling in research data management but also leaves the data in a format ready for data analysis via advanced methods. Exemplary, the data management is shown for literature search, experimental and simulation data entry, analysis, and storage as well as research planning. 

To enhance accessibility for individuals with varying levels of data literacy, the examples provided cater to different skill sets and interests. While the document extensively elucidates the overarching semantic framework, the application instances are tailored towards researchers with a practical orientation. For those seeking an introduction to this evolving landscape of Research Data Management (RDM), platforms like the Lara Suite, ELN FURTHRmind, or local Digital Labs offer valuable insights into data infrastructure and automation solutions. Advanced users can delve deeper into platforms such as LARAsuite or Nomad, while experts can actively integrate specialized applications like ADACTA, NOMAD, or the Cross Domain Meta Ontology into their projects.

Evolution of Tidally Truncated Globular Clusters with Anisotropy

Publisher: name: arXiv
Year: 1997

description: The evolution of tidally truncated globular clusters is investigated by integrating two-dimensional Fokker-Planck equation that allows the development of velocity anisotropy. We start from the isotropic Plummer model with tidal cut off and followed the evolution through the corecollapse. The heating by three-binary is included to obtain the evolution past the corecollapse. The anisotropy in velocity dispersion develops during the precollapse evolution. However, the anisotropy becomes highly depressed during the post-collapse evolution because of rapid loss of radial orbits. Maximum radial anisotropy appears just after the beginning of the expansion, and degree of anisotropy decreases slowly as the total mass of the cluster decreases. Thus it may be possible to determine the evolutionary status of a cluster if the velocity anisotropy can be measured in the sense that the postcollapse clusters always have very little degree of anisotropy. The structure of the post-collapse cluster can be well fitted to King models because the degree of anisotropy is rather small.

description: Multidimensional systems are becoming increasingly important as they provide a promising tool for estimation, simulation and control, while going beyond the traditional setting of one-dimensional systems. The analysis of multidimensional systems is linked to multivariate polynomials, and is therefore more difficult than the well-known analysis of one-dimensional systems, which is linked to univariate polynomials. In the current paper we relate the realization theory for overdetermined autonomous multidimensional systems to the problem of solving a system of polynomial equations. We show that basic notions of linear algebra suffice to analyze and solve the problem. The difference equations are associated with a Macaulay matrix formulation, and it is shown that the null space of the Macaulay matrix is a multidimensional observability matrix. Application of the classical shift trick from realization theory allows for the computation of the corresponding system matrices in a multidimensional state-space setting. This reduces the task of solving a system of polynomial equations to computing an eigenvalue decomposition. We study the occurrence of multiple solutions, as well as the existence and analysis of solutions at infinity, which allow for an interpretation in terms of multidimensional descriptor systems.

J´ai decrit cette espece d'apres un type unique, provenant de Dakar (Senegal), el qu ¡ devait etre une ouvriere media, a en juger par la forme de sa tete non retrecie en arriere. Sans connaitre l'ouvriere major, je rattachais cette espece au groupe du Camp. foraminosus Forel, et cette hypothese est aujourd'hui confirmee par la decouverte de la femelle, que j'ai recue de Sierra-Leone et dont l'identification avec l'ouvriere ne me parait laisser prise a aucun doute. En voici la description:
Femelle. En tout semblable a l'ouvriere pour la couleur d´un noir mat, la sculpture et les autres caracteres, sauf les differences suivantes: Independamment de la sculpture fonciere, la tete offre les gros points-fossettes caracteristiques des especes du groupe. Ces fossettes sont plus grandes et plus profondes sur les joues, plus faibles sur l'epistome, le front et le vertex, et disparaissent sur l'oc ciput. Le scape des antennes est bien moins dilate que chez l'ouvriere. Le metanotum est creuse en arriere, a la jonction de ses faces basale et declive, d'un large sillon longitudinal qui produit, de chaque cote, deux saillies tuberculeuses rappelant la conformation de cette partie chez l'ouvriere; la sculpture du thorax est un peu plus fine que chez cette derniere et la pubescence blanche de l'abdomen est plus distincte, quoique tres eparse. Ailes fortement enfumees sur leur moilie basale; stigma d'un brun fonce, nervures d'un brun clair. - Long., 12 - 13 mill.

description: ``Natural'' inflationary theories are a class of models in which inflation is driven by a pseudo-Nambu-Goldstone boson. In this paper we consider two models, one old and one new, in which the potential for inflation is generated by loop effects from a fermion sector which explicitly breaks a global $U(1)$ symmetry. In both models, we retrieve the ``standard'' natural inflation potential, $V\left(θ\right) = Λ^4\left[1 + \cos\left(θ/ μ\right)\right]$, as a limiting case of the exact one-loop potential, but we carry out a general analysis of the models including the limiting case. Constraints from the COBE DMR observation and from theoretical consistency are used to limit the parameters of the models, and successful inflation occurs without the necessity of fine-tuning the parameters.

Depuis, j'ai recu de Sierra-Leone plusieurs autres individus, mais seulement des ouvrieres media et minor, sans aucune ouvriere major. L'ouvriere minor, qui est de meme taille que la media, se distingue de cette derniere par sa tete plus ou moins retrecie en arriere, avec le bord posterieur arrondi et les angles non saillants.

description: A number of ultracompact H II regions in Galactic star forming environments have been observed to vary significantly in radio flux density on timescales of 10-20 years. Theory predicted that such variations should occur when the accretion flow that feeds a young massive star becomes unstable and clumpy. We have targeted the massive star-forming region W49A with the Karl G. Jansky Very Large Array (VLA) for observations at 3.6 cm with the B-configuration at 0.8'' resolution, to compare to nearly identical observations taken almost 21 years earlier (February 2015 and August 1994). Most of the sources in the crowded field of ultracompact and hypercompact H II regions exhibit no significant changes over this time period. However, one source, W49A/G2, decreased by 20% in peak intensity (from 71+/-4 mJy/beam to 57+/-3 mJy/beam), and 40% in integrated flux (from 0.109+/-0.011 Jy to 0.067+/-0.007 Jy), where we cite 5 sigma errors in peak intensity, and 10% errors in integrated flux. We present the radio images of the W49A region at the two epochs, the difference image that indicates the location of the flux density decrease, and discuss explanations for the flux density decrease near the position of W49A/G2.

description: We discuss the possibility that gamma-ray bursts result from internal shocks in an ultra-relativistic matter. Using a simple model we calculate the temporal structure and we estimate the efficiency of this process. In this model the ultra-relativistic matter flow is represented by a succession of shells with random values of the Lorentz factor. We calculate the shocks that take place between those shells and we estimate the resulting emission. Internal shocks can produce the highly variable temporal structure observed in most of the bursts provided that the source emitting the relativistic flow is highly variable. The observed peaks are in almost one to one correlation to the activity of the emitting source. A large fraction of the kinetic energy is converted to radiation. The most efficient case is when an inner engine produces shells with comparable energy but very different Lorentz factors. It also gives the most preferable temporal structure.

The Legal Implications Of Non-Performing Assets On The Indian Economy: A Comprehensive Analysis
Creators: name: Dr.Santosh Sharma
Publisher: name: Zenodo
Year: 2024

description: Concerns about non-performing assets (NPAs) have grown inside the Indian banking industry. exerting significant pressure on financial institutions and impacting the broader economy. This paper explores the intricate relationship between NPAs, legal frameworks, and their ramifications for India's economic landscape. Through a thorough examination of existing literature, regulatory provisions, and case studies, it sheds light on the multifaceted legal dimensions of NPAs and their implications. The firstpart of the study outlines the legal framework that governs debt recovery and the resolution of nonperforming assets (NPAs) in India. The Insolvency and Bankruptcy Code (IBC) and other pertinent statutes will be specifically highlighted. It clarifies the function of oversight bodies like the Reserve Bank of India (RBI), in overseeing asset quality and enforcing prudential norms to address NPA-related challenges. Furthermore, the paper delves into the impact of NPAs .on credit availability, investment climate, andfinancial stability. It underscores how delayed legal proceedings and inadequate enforcement mechanisms hinder effective NPA resolution, exacerbating systemic risks and impeding economic growth. Through empirical evidence and case studies, the paper highlights the practical implications of NPAs on banks' balance sheets, capital adequacy, and lending behaviour. It also examines the role of alternative mechanisms, such as asset reconstruction companies and debt restructuring frameworks, in mitigatingNPA-related risks. Ultimately, this paper underscores the imperative of a robust legal infrastructure to address the NPA crisis effectively. It advocates for reforms aimed at expediting debt recovery processes, enhancing creditor rights, and strengthening regulatory oversight to restore confidence in the banking sector and foster sustainable economic development in India
Numerical scheme for simulation of transient flows of non-Newtonian fluids characterised by a non-monotone relation between the symmetric part of the velocity gradient and the Cauchy stress tensor

description: We propose a numerical scheme for simulation of transient flows of incompressible non-Newtonian fluids characterised by a non-monotone relation between the symmetric part of the velocity gradient (shear rate) and the Cauchy stress tensor (shear stress). The main difficulty in dealing with the governing equations for flows of such fluids is that the non-monotone constitutive relation allows several values of the stress to be associated with the same value of the symmetric part of the velocity gradient. This issue is handled via a reformulation of the governing equations. The equations are reformulated as a system for the triple pressure-velocity-apparent viscosity, where the apparent viscosity is given by a scalar implicit equation. We prove that the proposed numerical scheme has---on the discrete level---a solution, and using the proposed scheme we numerically solve several flow problems.

description: Quantitative magnetic resonance imaging (qMRI) allows images to be compared across sites and time points, which is particularly important for assessing long-term conditions or for longitudinal studies. The multiparametric mapping (MPM) protocol is used to acquire images with conventional clinical contrasts, namely PD-, T1-, and MT-weighted volumes. Through multi-echo acquisition for each contrast and variations in flip angles between PD- and T1-weighted contrasts, parameter maps, such as proton density (PD), longitudinal relaxation rate (R1), apparent transverse relaxation rate (R2$^*$), and magnetization transfer saturation (MT$_{sat}$), can be estimated. Various algorithms have been employed to estimate these parameters from the acquired volumes. This paper extends an existing maximum a posteriori approach, which uses joint total variation regularization, by transitioning from a Gaussian noise approximation to a more physically plausible model that assumes noncentral chi-distributed noise.

We first discuss the quantum numbers of these systems, including charge conjugation. Two types of systems are discussed in detail: ``gluelumps'' which have a heavy adjoint color charge at the origin and glueballs which are composed entirely of glue. Both systems are discussed using the bag model and the flux tube model. For glueballs the model spectra are compared with the resulst of Teper. Both models capture many features of the numerical results.

description: Background: Using sentiment analysis to study software developers' behavior comes with challenges such as the presence of a large amount of technical discussion unlikely to express any positive or negative sentiment. However, emoticons provide information about developer sentiments that can easily be extracted from software repositories. Aim: We investigate how software developers use emoticons differently in issue trackers in order to better understand the differences between developers and determine to which extent emoticons can be used as in place of sentiment analysis. Method: We extract emoticons from 1.3M comments from Apache's issue tracker and 4.5M from Mozilla's issue tracker using regular expressions built from a list of emoticons used by SentiStrength and Wikipedia. We check for statistical differences using Mann-Whitney U tests and determine the effect size with Cliff's delta. Results: Overall Mozilla developers rely more on emoticons than Apache developers. While the overall ratio of comments with emoticons is of 2% and 3.6% for Apache and Mozilla, some individual developers can have a ratio above 20%. Looking specifically at Mozilla developers, we find that western developers use significantly more emoticons (with large size effect) than eastern developers. While the majority of emoticons are used to express joy, we find that Mozilla developers use emoticons more frequently to express sadness and surprise than Apache developers. Finally, we find that developers use overall more emoticons during weekends than during weekdays, with the share of sad and surprised emoticons increasing during weekends. Conclusions: While emoticons are primarily used to express joy, the more occasional use of sad and surprised emoticons can potentially be utilized to detect frustration in place of sentiment analysis among developers using emoticons frequently enough.

The Problem of Time in the Quantum Theory of Black Holes

description: We discuss the problem of time in spherically symmetric pure Einstein gravity with the cosmological term by using an exact solution to the Wheeler-DeWitt equation. A positive definite inner product is defined, based on the momentum constraint rather than the hamiltonian constraint. A natural notion of time is introduced via the Heisenberg equation. This notion enables one to reproduce the time-time component of the classical metric. Non-Hermiticity of the hamiltonian is essential in the definition of time.

Thinging for Software Engineers

description: The aim of this paper is to promote the terms thing and thinging (which refers to the act of defining a boundary around some portion of reality and labeling it with a name) as valued notions that play an important role in software engineering modeling. Additionally, we attempt to furnish operational definitions for terms thing, object, process, and thinging. The substantive discussion is based on the conception of an (abstract) machine, named the Thinging Machine (TM), used in several research works. The TM creates, processes, receives, releases, and transfers things. Accordingly, a diagrammatic representation of the TM is used to model reality. In the discussion section, this paper clarifies interesting issues related to conceptual modeling in software engineering. The substance of this paper and its conclusion suggest that thinging should be more meaningfully emphasized as a valuable research and teaching topic, at least in the requirement analysis phase of the software development cycle.

description: The suggestion of momentum dependence in the amplitude for rho-omega mixing has generated concern over related implications for vector meson dominance and the photon-rho coupling. We discuss two established representations of vector meson dominance and show that one of these is completely consistent with such a coupling. We then apply it to a calculation of the pion electromagnetic form-factor. Our analysis leads to a new value for the on-shell rho-omega mixing amplitude of (-3800 +/- 370) MeV^2.

Ouvriere. Taille tres petite (4 1 / 2 - 5 mill.). Tout le corps plus trapu et moins allonge que chez l´ Oe. smaragdina Fab.; le scape depasse l'occiput de moins de moitie de sa longueur, les articles du funicule sont beaucoup moins allonges et les quatre avant-derniers sont seulement un peu plus longs que larges. Le thorax est moins grele, le mesonotum moins fortement etrangle. Le petiole est remarquablement court, moins de deux fois aussi long que haut et fortement epaissi en arriere en forme de n oe ud. Ce n oe ud est largement sillonne en-dessus et echancre en arriere de facon a former deux lobes arrondis, analogues a ceux que presente le second article du petiole de certains Cremastogaster. Tout le corps est ferrugineux avec l'abdomen rembruni. Les autres caracteres sont ceux de l´ Oe. smaragdina.
J'ai recu quelques exemplaires de cette fourmi en meme temps qu'un grand nombre d' Oe. smaragdina. Malgre les variations que presenle cette derniere espece, la brevinodis s'en eloigne par des caracteres tellement frappants que je suis oblige de l'en separer, avec d'autant plus de raison que tous les individus que j'ai sous les yeux sont identiques et que je n'ai pas rencontre un seul exemplaire de transition entre les deux formes.

description: The "golden" channel, in which the newly-discovered Higgs boson decays to four leptons by means of intermediate vector bosons, is important for determining the properties of the Higgs boson and for searching for subtle new physics effects. Different approaches exist for parametrizing the relevant Higgs couplings in this channel; here we relate the use of pseudo-observables to methods based on specifying the most general amplitude or Lagrangian terms for the $HVV$ interactions. We also provide projections for sensitivity in this channel in several novel scenarios, illustrating the use of pseudo-observables, and analyze the role of kinematic distributions and (ratios of) rates in such $H\to4\ell$ studies.

description: We show that evolution of the luminosity density of galaxies in the universe provides a powerful test for the geometry of the universe. Using reasonable galaxy evolution models of population synthesis which reproduce the colors of local galaxies of various morphological types, we have calculated the luminosity density of galaxies as a function of redshift $z$. Comparison of the result with recent measurements by the Canada-France Redshift Survey in three wavebands of 2800Å, 4400Å, and 1 micron at z<1 indicates that the Λ-dominated flat universe with λ_0 \sim 0.8 is favored, and the lower limit on λ_0 yields 0.37 (99% C.L.) or 0.53 (95% C.L.) if Ω_0+λ_0=1. The Einstein-de Sitter universe with (Ω_0, λ_0)=(1, 0) and the low-density open universe with (0.2, 0) are however ruled out with 99.86% C.L. and 98.6% C.L., respectively. The confidence levels quoted apply unless the standard assumptions on galaxy evolution are drastically violated. We have also calculated a global star formation rate in the universe to be compared with the observed rate beyond z \sim 2. We find from this comparison that spiral galaxies are formed from material accretion over an extended period of a few Gyrs, while elliptical galaxies are formed from initial star burst at z >~ 5 supplying enough amount of metals and ionizing photons in the intergalactic medium.

description: We analyze a large system of heterogeneous quadratic integrate-and-fire (QIF) neurons with time delayed, all-to-all synaptic coupling. The model is exactly reduced to a system of firing rate equations that is exploited to investigate the existence, stability and bifurcations of fully synchronous, partially synchronous, and incoherent states. In conjunction with this analysis we perform extensive numerical simulations of the original network of QIF neurons, and determine the relation between the macroscopic and microscopic states for partially synchronous states. The results are summarized in two phase diagrams, for homogeneous and heterogeneous populations, which are obtained analytically to a large extent. For excitatory coupling, the phase diagram is remarkably similar to that of the Kuramoto model with time delays, although here the stability boundaries extend to regions in parameter space where the neurons are not self-sustained oscillators. In contrast, the structure of the boundaries for inhibitory coupling is different, and already for homogeneous networks unveils the presence of various partially synchronized states not present in the Kuramoto model: Collective chaos, quasiperiodic partial synchronization (QPS), and a novel state which we call modulated-QPS (M-QPS). In the presence of heterogeneity partially synchronized states reminiscent to collective chaos, QPS and M-QPS persist. In addition, the presence of heterogeneity greatly amplifies the differences between the incoherence stability boundaries of excitation and inhibition. Finally, we compare our results with those of a traditional (Wilson Cowan-type) firing rate model with time delays. The oscillatory instabilities of the traditional firing rate model qualitatively agree with our results only for the case of inhibitory coupling with strong heterogeneity.

description: Cosmic strings in realistic particle physics models have fermion zero modes in the string core. Such zero modes change the underlying cosmology; for example, the string can carry a current. We consider the stability of fermion zero modes to interactions with particles in the surrounding plasma. We also consider cosmological constraints on such theories, particulary those with a chiral fermion zero mode, such as arises in a class of supersymmetric models.
