description: Automatically providing suggestions for predicting the likely status of a mechanical component is a key challenge in a wide variety of industrial domains. Existing solutions based on ontological models have proven to be appropriate for fault diagnosis, but they fail when suggesting activities leading to a successful prognosis of mechanical components. The major reason is that fault prognosis is an activity that, unlike fault diagnosis, involves a lot of uncertainty and it is not always possible to envision a model for predicting possible faults. In this work, we propose a solution based on massive text mining for automatically suggesting prognosis activities concerning mechanical components. The great advantage of text mining is that it is possible to automatically analyze vast amounts of unstructured information in order to find strategies that have been successfully exploited, and formally or informally documented, in the past in any part of the world.

In particular we give the lowest order equations of motion and resolve a puzzle concerning the counting of massless modes that was reported in hep-th/9906094. In order to find agreement with black hole entropy and anomaly inflow arguments we propose that some of the moduli become massive.

Taming the Rotating Wave Approximation

description: The interaction between light and matter is one of the oldest research areas of quantum mechanics, and a field that just keeps on delivering new insights and applications. With the arrival of cavity and circuit quantum electrodynamics we can now achieve strong light-matter couplings which form the basis of most implementations of quantum technology. But quantum information processing also has high demands requiring total error rates of fractions of percentage in order to be scalable (fault-tolerant) to useful applications. Since errors can also arise from modelling, this has brought into center stage one of the key approximations of quantum theory, the Rotating Wave Approximation (RWA) of the quantum Rabi model, leading to the Jaynes-Cummings Hamiltonian. While the RWA is often very good and incredibly useful to understand light-matter interactions, there is also growing experimental evidence of regimes where it is a bad approximation. Here, we ask and answer a harder question: for which experimental parameters is the RWA, although perhaps qualitatively adequate, already not good enough to match the demands of scalable quantum technology? For example, when is the error at least, and when at most, 1%? To answer this, we develop rigorous non-perturbative bounds taming the RWA.
 We find that these bounds not only depend, as expected, on the ratio of the coupling strength and the oscillator frequency, but also on the average number of photons in the initial state. This confirms recent experiments on photon-dressed Bloch-Siegert shifts. We argue that with experiments reporting controllable cavity states with hundreds of photons and with quantum error correcting codes exploring more and more of Fock space, this state-dependency of the RWA is increasingly relevant for the field of quantum computation, and our results pave the way towards a better understanding of those experiments.

We prove a similar result for groups of area-preserving homeomorphisms without the hypothesis that the orders of group elements are powers of 2 provided there is an element of even order.

description: The dynamical scenario is considered for N=1 SQCD, with N_c colors and N_c\neq 0, while quarks alone don't condense, ==0, so that the color is confined. Such condensation of quarks results in formation of dynamical constituent masses μ_C \gg m_Q of quarks and appearance of light "pions" (similarly to QCD). The mass spectrum of SQCD in this phase is described and comparison with the Seiberg dual description is performed. It is shown that the direct and dual theories are different (except, possibly, for the perturbative strictly superconformal regime).

description: A fundamental challenge in the intersection of Artificial Intelligence and Databases consists of developing methods to automatically manage Knowledge Bases which can serve as a knowledge source for computer systems trying to replicate the decision-making ability of human experts. Despite of most of the tasks involved in the building, exploitation and maintenance of KBs are far from being trivial, and significant progress has been made during the last years. However, there are still a number of challenges that remain open. In fact, there are some issues to be addressed in order to empirically prove the technology for systems of this kind to be mature and reliable.
Transformative Education, Global Citizenship Education and Education for Sustainable Development. An Exploration. Dossier by the Advisory Board "Transformative Education | Global Citizenship Education" of the Austrian Commission for UNESCO.

Transformative Education

description: The term transformative education (or transformative learning TL) has become increasingly significant for UNESCO in recent years (UNESCO 2021a)[1]. The biannual global UNESCO forums as well as new types of events held specifically on this topic, such as the 2022 Transforming Education UN/UNESCO Summit[2], highlight this importance.

Against this backdrop, the Austrian Commission for UNESCO established the Advisory Board on “Transformative Education/Global Citizenship Education” (TE/GCED) in 2017.This terminology is also becoming more widespread in academic discourse, whereby reference is often, but not exclusively, made to education for sustainable development (ESD) in the German-speaking world, while the TE—ESD—GCED conceptual triangle usually forms the basis for UNESCO.

In 2022, the Advisory Board was commissioned to work on this conceptual triangle in relation to UNESCO and the Austrian context. The purpose of the paper of the advisory board is to clarify the terms transformative education – global citizenship education – education for sustainable development and to demonstrate the links between them. Moreover, it aims to shed light on both the educational policy and overall political contexts which form the back-ground for the current discussion concerning and surrounding these concepts.

description: In the report there are presented the general frameworks for the quartet-metric gravity based upon the two physical concepts. First, there exist in space-time the distinct dynamical coordinates, given by a scalar quartet, playing the role of the Higgs fields for gravity. Second, the physical gravity fields arising due to the spontaneous symmetry breaking serve as the dark components of the Universe. It is argued that the mere admixture to metric of the scalar quartet may give rise to an extremely wide spectrum of the emergent gravity phenomena beyond General Relativity (GR). Developing the proposed frameworks further to find out the next-to-GR theory of gravity is a challenge.

A 3-D sunspot model derived from an inversion of spectropolarimetric observations and its implications for the penumbral heating
Creators: name: Beck, C.
Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: I deduced a 3-D sunspot model that is in agreement with spectropolarimetric observations, to address the question of penumbral heating by the repetitive rise of flow channels. I performed inversions of data taken simultaneously in infrared and visible spectral lines. I used two independent magnetic components to reproduce the irregular Stokes profiles in the penumbra. I studied the averaged and individual properties of the two components. By integrating the field inclination to the surface, I developed a 3-D model of the spot from inversion results without intrinsic height information. I find that the Evershed flow is harbored by the weaker of the two field components. This component forms flow channels that show upstreams in the inner and mid penumbra, continue horizontally as slightly elevated loops throughout the penumbra, and finally bend down in the outer penumbra. I find several examples, where two or more flow channels are found along a radial cut from the umbra to the outer boundary of the spot. I find that a model of horizontal flow channels in a static background field is in good agreement with the observed spectra. The properties of the flow channels correspond very well to the simulations of Schlichenmaier et al. (1998). From the temporal evolution in intensity images and the properties of the flow channels in the inversion, I conclude that interchange convection of rising hot flux tubes in a thick penumbra still seems a possible mechanism for maintaining the penumbral energy balance.

Homotopy type of the neighborhood complexes of graphs of maximal degree at most $3$ and $4$-regular circulant graphs

description: To estimate the lower bound for the chromatic number of a graph $G$, Lovász associated a simplicial complex $\mathcal{N}(G)$ called the neighborhood complex and relates the topological connectivity of $\mathcal{N}(G)$ to the chromatic number of $G$. More generally he proved that the chromatic number of $G$ is bounded below by the topological connectivity of $\mathcal{N}(G)$ plus $3$. In this article, we consider the graphs of maximal degree at most $3$ and $4$-regular circulant graphs. We show that each connected component of the neighborhood complexes of these graphs is homotopy equivalent either to a point, to a wedge sum of circles, to a wedge sum of $2$-spheres $S^2$, to $S^3$, to a garland of $2$-spheres $S^2$ or to a connected sum of tori.

description: The small-scale structure of a string connecting a pair of static sources is explored for the weakly-coupled anisotropic SU(2) Yang-Mills theory in (2+1) dimensions. A crucial ingredient in the formulation of the string Hamiltonian is the phenomenon of color smearing of the string constituents. The quark-anti-quark potential is determined. We close with some discussion of the standard, fully Lorentz-invariant Yang-Mills theory.

Superfluid Fermi-Fermi mixture: phase diagram, stability, and soliton formation

description: We study the phase diagram for a dilute Bardeen-Cooper-Schrieffer superfluid Fermi-Fermi mixture (of distinct mass) at zero temperature using energy densities for the superfluid fermions in one (1D), two (2D), and three (3D) dimensions. We also derive the dynamical time-dependent nonlinear Euler-Lagrange equation satisfied by the mixture in one dimension using this energy density. We obtain the linear stability conditions for the mixture in terms of fermion densities of the components and the interspecies Fermi-Fermi interaction. In equilibrium there are two possibilities. The first is that of a uniform mixture of the two components, the second is that of two pure phases of two components without any overlap between them. In addition, a mixed and a pure phase, impossible in 1D and 2D, can be created in 3D. We also obtain the conditions under which the uniform mixture is stable from an energetic consideration. The same conditions are obtained from a modulational instability analysis of the dynamical equations in 1D. Finally, the 1D dynamical equations for the system are solved numerically and by variational approximation (VA) to study the bright solitons of the system for attractive interspecies Fermi-Fermi interaction in 1D. The VA is found to yield good agreement to the numerical result for the density profile and chemical potential of the bright solitons. The bright solitons are demonstrated to be dynamically stable. The experimental realization of these Fermi-Fermi bright solitons seems possible with present setups.

Transformative Bildung

description: Der Begriff Transformative Bildung (oder auch Transformatives Lernen TL) hat für die UNESCO in den vergangenen Jahren zunehmend an Bedeutung gewonnen (UNESCO 2021a).[1] Dies lässt sich an den globalen UNESCO Foren, die im zweijährigen Rhythmus abgehalten werden, ebenso ablesen wie an neuen Veranstaltungsformaten, die speziell zu dieser Thematik abgehalten werden, wie dem UN/UNESCO Transforming Education Summit 2022.[2]

In diesem Sinne hat die Österreichische UNESCO-Kommission 2017 den Fachbeirat „Transformative Bildung/Global Citizenship Education“ (TB/GCED) eingerichtet. Zugleich ist der Term auch im wissenschaftlichen Diskurs im Vormarsch, wobei im deutschen Sprachraum häufig, aber nicht ausschließlich, ein Bezug zu Bildung für nachhaltige Entwicklung (BNE) hergestellt wird, während die UNESCO meist von einem begrifflichen Dreieck TB – BNE – GCED ausgeht.

2022 wurde der Fachbeirat beauftragt dieses begriffliche Dreieck in Bezug auf UNESCO und den österreichischen Kontext zu bearbeiten. Das soeben erschienene Dossier des Fachbeirats hat sich zur Aufgabe gestellt, die Begriffe Transformative Bildung – Global Citizenship Education – Bildung für Nachhaltige Entwicklung einerseits klarer zu fassen und andererseits Verbindungslinien zwischen ihnen aufzuzeigen. Darüber hinaus sollen sowohl der bildungspolitische wie auch der gesamtpolitische Kontext erhellt werden, auf deren Hintergrund sich die gegenwärtige Diskussion mit diesen und um diese Konzepte abspielt.

When woody perennials are going to be included in grasslands areas they would be better suited if they provide some benefits to the system such as for example (i) the type of tree, legume woody perennials are able to increase pasture production than not legume woody perennials, (ii) the form and distribution of the woody perennial that allows water and light to reach the soil are better than those that generates a lot of shade that limits grass production or the (iii) palatability and quality of the woody perennials from a grazing perspective.

description: We show that a recently proposed solution to the Hierarchy Problem simultaneously solves the Strong CP Problem, without requiring an axion or any further new physics. Consistency of black hole physics implies a non-trivial relation between the number of particle species and particle masses, so that with ~10^{32} copies of the standard model, the TeV scale is naturally explained. At the same time, as shown here, this setup predicts a typical expected value of the strong-CP parameter in QCD of theta ~ 10^{-9}. This strongly motivates a more sensitive measurement of the neutron electric dipole moment.

Search for $\mathrm{t\overline{t}}$H production in the H $\rightarrow$ $\mathrm{b\overline{b}}$ decay channel with leptonic $\mathrm{t\overline{t}}$ decays in proton-proton collisions at $\sqrt{s} =$ 13 TeV

description: A search is presented for the associated production of a standard model Higgs boson with a top quark-antiquark pair ($\mathrm{t\overline{t}}$H), in which the Higgs boson decays into a b quark-antiquark pair, in proton-proton collisions at a centre-of-mass energy $\sqrt{s} =$ 13 TeV. The data correspond to an integrated luminosity of 35.9 fb$^{-1}$ recorded with the CMS detector at the CERN LHC. Candidate $\mathrm{t\overline{t}}$H events are selected that contain either one or two electrons or muons from the $\mathrm{t\overline{t}}$ decays and are categorised according to the number of jets. Multivariate techniques are employed to further classify the events and eventually discriminate between signal and background. The results are characterised by an observed $\mathrm{t\overline{t}}$H signal strength relative to the standard model cross section, $μ= σ$ / $σ_{\mathrm{SM}}$, under the assumption of a Higgs boson mass of 125 GeV. A combined fit of multivariate discriminant distributions in all categories results in an observed (expected) upper limit on $μ$ of 1.5 (0.9) at 95% confidence level, and a best fit value of 0.72 $\pm$ 0.24 (stat) $\pm$ 0.38 (syst), corresponding to an observed (expected) signal significance of 1.6 (2.2) standard deviations above the background-only hypothesis.

description: Understanding quantum thermalization through entanglement build-up in isolated quantum systems addresses fundamental questions on how unitary dynamics connects to statistical physics. Here, we study the spin dynamics and approach towards local thermal equilibrium of a macroscopic ensemble of S = 3 spins prepared in a pure coherent spin state, tilted compared to the magnetic field, under the effect of magnetic dipole-dipole interactions. The experiment uses a unit filled array of 104 chromium atoms in a three dimensional optical lattice, realizing the spin-3 XXZ Heisenberg model. The buildup of quantum correlation during the dynamics, especially as the angle approaches pi/2, is supported by comparison with an improved numerical quantum phase-space method and further confirmed by the observation that our isolated system thermalizes under its own dynamics, reaching a steady state consistent with the one extracted from a thermal ensemble with a temperature dictated from the system's energy. This indicates a scenario of quantum thermalization which is tied to the growth of entanglement entropy. Although direct experimental measurements of the Renyi entropy in our macroscopic system are unfeasible, the excellent agreement with the theory, which can compute this entropy, does indicate entanglement build-up.

We find that the hyperon bulk viscosity coefficient in the presence of antikaon condensate is suppressed compared with the case without the condensate. The suppressed hyperon bulk viscosity in the superconducting phase is still an efficient mechanism to damp the r-mode instability in neutron stars.

description: We prove a relation between the scaling $h^β$ of the elastic energies of shrinking non-Euclidean bodies $S_h$ of thickness $h\to 0$, and the curvature along their mid-surface $S$. This extends and generalizes similar results for plates [BLS16, LRR] to any dimension and co-dimension. In particular, it proves that the natural scaling for non-Euclidean rods with smooth metric is $h^4$, as claimed in [AAE+12] using a formal asymptotic expansion. The proof involves calculating the $Γ$-limit for the elastic energies of small balls $B_h(p)$, scaled by $h^4$, and showing that the limit infimum energy is given by a square of a norm of the curvature at a point $p$. This $Γ$-limit proves asymptotics calculated in [AKM+16].

The points in X are certain monomial valuations, and X admits a natural structure of Euclidean CW-complex of dimension n-1. When n = 3, and for K of characteristic zero, we prove that X has non-positive curvature and is simply connected, hence is a CAT(0) space. As an application we obtain the linearizability of finite subgroups in Tame($K^3$).

description: Perfectly Matched Layer (PML) is a widely adopted non-reflecting boundary treatment for wave simulations. Reducing numerical reflections from a discretized PML has been a long lasting challenge. This paper presents a new discrete PML for the multi-dimensional scalar wave equation which produces no numerical reflection at all. The reflectionless discrete PML is discovered through a straightforward derivation using Discrete Complex Analysis. The resulting PML takes an easily-implementable finite difference form with compact stencil. In practice, the discrete waves are damped exponentially in the PML, and the error due to domain truncation is maintained at machine zero by a moderately thick PML. The numerical stability of the proposed PML is also demonstrated.

description: The search for the chiral magnetic effect (CME) in relativistic heavy-ion collisions helps us understand the $\mathcal{CP}$ symmetry breaking in strong interactions and the topological nature of the QCD vacuum. Since the background and signal of the CME have different correlations with the spectator and participant planes, a two-plane method has been proposed to extract the fraction of the CME signal inside the CME observable of $Δγ$ from the experimental measurements relative to the two planes. Using a multiphase transport model with different strengths of the CME, we reexamine the two-plane method in isobar collisions at $\sqrt{s_{_{\rm NN}}} = 200$ GeV. The ratios of the CME signals and the elliptic flow backgrounds relative to the two different planes are found to be different, which is inconsistent with the assumptions made in the current experimental measurements. This difference arises from the decorrelation effect of the chiral magnetic effect relative to the spectator and participant planes caused by final state interactions. Our finding suggests that the current experimental measurements may overestimate the fraction of the CME signal in the CME observable in the final state of relativistic heavy-ion collisions.

description: The heart exhibits complex systems behaviors during atrial fibrillation (AF), where the macroscopic collective behavior of the heart causes the microscopic behavior. However, the relationship between the downward causation and scale is nonlinear. We describe rotors in multiple spatiotemporal scales by generating a renormalization group from a numerical model of cardiac excitation, and evaluate the causal architecture of the system by quantifying causal emergence. Causal emergence is an information-theoretic metric that quantifies emergence or reduction between microscopic and macroscopic behaviors of a system by evaluating effective information at each spatiotemporal scale. We find that there is a spatiotemporal scale at which effective information peaks in the cardiac system with rotors. There is a positive correlation between the number of rotors and causal emergence up to the scale of peak causation. In conclusion, one can coarse-grain the cardiac system with rotors to identify a macroscopic scale at which the causal power reaches the maximum. This scale of peak causation should correspond to that of the AF driver, where networks of cardiomyocytes serve as the causal units. Those causal units, if identified, can be reasonable therapeutic targets of clinical intervention to cure AF.

description: We determine under what conditions Scalar Tensor cosmologies predict an expansion rate which is reduced as compared to the standard General Relativity case. We show that ST theories with a single matter sector typically predict an enchanced Hubble rate in the past, as a consequence of the requirement of an attractive fixed point towards General Relativity at late times. Instead, when additional matter sectors with different conformal factors are added, the late time convergence to General Relativity is mantained and at the same time a reduced expansion rate in the past can be driven. For suitable choices of the parameters which govern the scalar field evolution, a sizeable reduction (up to about 2 orders of magnitude) of the Hubble rate prior to Big Bang Nucleosynthesis can be obtained. We then discuss the impact of these cosmological models on the relic abundance of dark matter is minimal Supergravity models: we show that the cosmologically allowed regions in parameter space are significantly enlarged, implying a change in the potential reach of LHC on the neutralino phenomenology.

Vie académique

description: [transcription] Monsieur

Il ne m'a pas été possible encore de tenir la promesse que j'eus l'honneur de vous faire l'année dernière, au sujet des cailloux de Remusat. Plusieurs personnes que j'avois chargées de ma commission s'en sont très mal acquitté; et de trente pierres qui m'ont été procurées, une seule peut vous être offerte car ces cailloux n'ont quelque valeur, qu'autant qu'ils renferment des crystallisations. Celui que vous recevrés, a été cassé fort à propos. Sa forme extérieure est assés singulière; et l'oeil peut en découvrir intus toute l'organisation. Il est à remarquer aussi que les crystallisations ont d'autant plus d'éclat, qu'elles ont moins de volume. L'explication de ce phénomène et de leur formation est réservée à votre pénétration. Ces deux points d'histoire [v] naturelle et de physique exigent, Monsieur, autant de profondeur et de génie que vous en avez.

Je ne sçais si vous avez dans votre musée, des ostracites de Valréas. Ces coquillages pétrifiés ont quelquefois deux et trois palmes de longueur; on les trouve dans une montagne, par couches horizontales. Je me ferai un vrai plaisir de vous en procurer, si vous en manquez; vous n'avés qu'à parler, Monsieur. Je désirerois bien pouvoir vous offrir des morceaux plus rares; mais j'habite un pays stérile en histoire naturelle, comme en urbanité et en ressources; quelques honnêtes gens exceptés, il y règne presqu'autant d'ignorance et de barbarie qu'à Tripoli et à Salé. D'où je crois pouvoir conjecturer que l'insensibilité et la rudesse du caractère des habitans d'un pays quelconque, est toujours en raison composée de l'ingratitude du sol, et de l'horreur qu'inspirent les objets dont la vue est habituellement frappée. M. de Vérone eût été toute ma société, si je n'eusse eu le malheur de le perdre.

Je prends la liberté de vous addresser un Mémoire sur la médecine morale; et de vous prier de vouloir bien le présenter à l'académie de Nismes où vous occupés une place si distinguée. Je serois infiniment flatté de son suffrage et du vôtre, Monsieur. J'ai déjà l'honneur d'être votre confrère [r] à l'académie de Dijon. Daignés être mon protecteur auprès de la vôtre, et l'assurer que rien ne me seroit plus agréable que si elle acceptoit mes travaux. Je ne dis pas mes talens, parce que je me connois. Je n'ai pour moi, que beaucoup d'envie de bien faire, du respect pour les sçavans et de l'amour pour les sciences.

J'ai l'honneur d'être avec respect

Monsieur

Votre très humble et très obéissant serviteur

Nicolas

D.M.

P.S. Celui qui vous portera mon envoy, Monsieur, pourroit se charger de votre réponse, dans 10 jours. Il va à Balaruc et logera à l'Orange.

Subjects: pastoral counselling, technology, Africa, teletherapy, mHealth, digital divide, cultural context, religion, mental health

description: This study explores the transformative impact of technology on pastoral care and counselling within the African context. Departing from traditional, in-person models, we investigate the integration of digital tools to enhance the delivery of spiritual and emotional support. Through a historical analysis of pastoral counselling in Africa and a contemporary examination of technology-mediated services, we identify opportunities and challenges in this evolving landscape. Our research employs case studies to evaluate the effectiveness of teletherapy, mHealth initiatives, and social media platforms in improving accessibility, affordability, and confidentiality. We critically assess the interplay between technology and factors such as the digital divide, privacy concerns, and cultural nuances. To optimize the benefits of technology, we propose a strategic framework encompassing training, capacity building, and collaborative partnerships. Our findings contribute to the growing discourse on technology and religion, providing actionable insights for policymakers, practitioners, and researchers seeking to enhance pastoral counselling in Africa. The authors gave recommendations that will make for improved pastoral care and counselling services in Africa

description: O presente estudo tem como principal objetivo analisar a situação económica e financeiramente o setor do turismo da região Norte de Portugal (NUT II), relacionando a sua competitividade e inovação a indicadores de crescimento, através de uma análise comparativa das empresas ativas no período de 2006 – 2016. Esta análise foi desenvolvida com base na Informação Empresarial Simplificada (IES) do Sistema de Balanços Ibéricos (SABI), procedeu-se à análise e tratamento dos indicadores económicos e financeiros referentes a 11 611 empresas ativas. Para além disso, pretendeu-se investigar em concreto as empresas localizadas na região financiadas pelo Sistema de Incentivo à Inovação alocado ao campo da competitividade e inovação no âmbito do Quadro de Referência Estratégica Nacional (QREN), através da aplicação de uma metodologia de análise contra factual. Podemos concluir a existência de uma relação direta entre os nove indicadores analisados (VN, ROA, VAB, PAT, LQD, AF, SOLV, END e o EBE), sendo que a grande maioria dos indicadores apresentaram taxas de crescimento negativas superiores a 35%, não apresentado qualquer vantagem competitiva, inovadora ou produtiva para as empresas. Comprovamos ainda a existência de uma relação direta de causa-efeito entre o recebimento do incentivo e os fatores de competitividade, concretamente, existe uma relação positiva em termos produtivos, por outro lado existe também uma relação negativa em termos financeiros.

description: Moduli spaces of (polarized) Enriques surfaces can be described as open subsets of modular varieties of orthogonal type. It was shown by Gritsenko and Hulek that there are, up to isomorphism, only finitely many different moduli spaces of polarized Enriques surfaces. Here we investigate the possible arithmetic groups and show that there are exactly $87$ such groups up to conjugacy. We also show that all moduli spaces are dominated by a moduli space of polarized Enriques surfaces of degree $1240$. Ciliberto, Dedieu, Galati, and Knutsen have also investigated moduli spaces of polarized Enriques surfaces in detail. We discuss how our enumeration relates to theirs. We further compute the Tits building of the groups in question. Our computation is based on groups and indefinite quadratic forms and the algorithms used are explained.
