description: Traditional solar flare forecasting approaches have mostly relied on physics-based or data-driven models using solar magnetograms, treating flare predictions as a point-in-time classification problem. This approach has limitations, particularly in capturing the evolving nature of solar activity. Recognizing the limitations of traditional flare forecasting approaches, our research aims to uncover hidden relationships and the evolutionary characteristics of solar flares and their source regions. Our previously proposed Sliding Window Multivariate Time Series Forest (Slim-TSF) has shown the feasibility of usage applied on multivariate time series data. A significant aspect of this study is the comparative analysis of our updated Slim-TSF framework against the original model outcomes. Preliminary findings indicate a notable improvement, with an average increase of 5\% in both the True Skill Statistic (TSS) and Heidke Skill Score (HSS). This enhancement not only underscores the effectiveness of our refined methodology but also suggests that our systematic evaluation and feature selection approach can significantly advance the predictive accuracy of solar flare forecasting models.

description: In 2003, Del Pino and Dolbeault [14] and Gentil [19] investigated, independently, best constants and extremals associated to Euclidean Lp-entropy inequalities for p > 1. In this work, we present some contributions in the Riemannian context. Namely, let (M,g) be a closed Riemannian manifold of dimension n >= 3. For 1 < p <= 2, we establish the validity of the sharp Riemannian Lp-entropy inequality int_M |u|^p log(|u|^p) dv_g <= n/p log ( A_{opt} int_M |Grad_g u|^p dv_g + B ) on all functions u em H^{1,p}(M) such that ||u||_{Lp(M)} = 1 for some constant B. Moreover, we prove that the first best constant A_{opt} is equal to the corresponding Euclidean one. Our approach is inspired on the Bakry, Coulhon, Ledoux and Sallof-Coste's idea [3] of getting Euclidean entropy inequalities as a limit case of suitable subcritical interpolation inequalities. It is conjectured that the inequality sometimes fails for p > 2.

description: Extracting communities using existing community detection algorithms yields dense sub-networks that are difficult to analyse. Extracting a smaller sample that embodies the relationships of a list of suspects is an important part of the beginning of an investigation. In this paper, we present the efficacy of our shortest paths network search algorithm (SPNSA) that begins with an "algorithm feed", a small subset of nodes of particular interest, and builds an investigative sub-network. The algorithm feed may consist of known criminals or suspects, or persons of influence. This sets our approach apart from existing community detection algorithms. We apply the SPNSA on the Enron Dataset of e-mail communications starting with those convicted of money laundering in relation to the collapse of Enron as the algorithm feed. The algorithm produces sparse and small sub-networks that could feasibly identify a list of persons and relationships to be further investigated. In contrast, we show that identifying sub-networks of interest using either community detection algorithms or a k-Neighbourhood approach produces sub-networks of much larger size and complexity. When the 18 top managers of Enron were used as the algorithm feed, the resulting sub-network identified 4 convicted criminals that were not managers and so not part of the algorithm feed. We also directly tested the SPNSA by removing one of the convicted criminals from the algorithm feed and re-running the algorithm; in 5 out of 9 cases the left out criminal occurred in the resulting sub-network.

PIDs

description: Over the course of their evolution, persistent identifiers (PIDs) have been primarily associated with static “research objects”, the most well-known being the DOI, Digital Object Identifier. Typically, these PIDs have been associated with the final output of the research process – such as a paper or report.
 In this session we will look at 2 approaches and practices and how PIDs and the surrounding metadata and infrastructure might support them in their processes to give a richer capture of the whole research process across multiple disciplines and workflows. We examine the sectional / component driven chaining of the Octopus publishing system and the narrative, declarative chronology of the RAiD PID and the arising infrastructure and policy implications. In doing so, we will discuss whether the declarative, interconnected nature of the resulting informational fabric is the closest global system yet to that envisioned by the early hypertext pioneers, such as Vannevar Bush and then Ted Nelson and Doug Englebart. Please list up to three questions or issues that your session will address Persistent Identifiers can now enable a more nuanced capture of process and practice – how do we bring about infrastructure and culture change to embed this How should this be reflected in the policy landscape? Are PIDs now becoming a “real hypertext” reflecting the visions of Bush, Englebart and Nelson in a way that the web failed to deliver?

Contro il populismo: forme di vita collettiva intelligente. In risposta a 11 domande su Olivetti

Populism

description: Roberto Ciccarelli focuses his reflections on the questions of community, territory, and intellectual work. He sees Olivetti’s community as “a civil constitution founded on the self-governance of territories, the good governance of cities, the networking of local institutions, and a rethinking of ‘intermediate bodies’”. A community that is foreign to any form of populism, right- or left-winged, and the ideas of community that they promote founded on property, on borders. He warns that, if Olivetti’s paternalism and holism are limiting, nevertheless the idea of an osmosis between business and territory, of a ‘making together’, can be a means to give value to citizenship as cultural, political and social participation by way of a platform that is not only digital but political, international, and opposed to the concept of smart city reserved for owners and consumers; an idea that is able to overcome individualisms and subjectivisms, through the activation of intellectual work seen as critical, clinical and conflictual.

Der Wandel vom Lehren zum Lernen im didaktischen Diskurs, der die gegenwärtigen Debatten über die Gestaltung von Unterricht bestimmt, ist jedoch auch dadurch gekennzeichnet, dass er zwar eine Verlagerung der Aktivitäten von der Lehrperson zu den Lernenden fordert, sich allerdings nicht der Frage stellt, wie durch Lehre und Unterricht Erziehung und Bildung hervorgebracht werden kann und wer und wie Lernen ver-antwortet wird. Der Beitrag vergleicht die Mathetik und die lernseitige Orientierung im Unterrichtsgeschehen und versucht die eigene Positionierung gegenüber anderen Konzepten aufzuzeigen.

description: One-shot decoupling is a powerful primitive in quantum information theory and was hypothesized to play a role in the black hole information paradox. We study black hole dynamics modeled by a trilinear Hamiltonian whose semiclassical limit gives rise to Hawking radiation. An explicit numerical calculation of the discretized path integral of the S-matrix shows that decoupling is exact in the continuous limit, implying that quantum information is perfectly transferred from the black hole to radiation. A striking consequence of decoupling is the emergence of an output radiation entropy profile that follows Page's prediction. We argue that information transfer and the emergence of Page curves is a robust feature of any multi-linear interaction Hamiltonian with a bounded spectrum.

The Role of Temporary Agency Employment in Tight Labor Markets

description: This paper examines the reasons why employers used and even increased their use of temporary help agencies during the tight labor markets of the 1990s. Based on case study evidence from the hospital and auto supply industries, we evaluate various hypotheses for this phenomenon. In high-skilled occupations, our results are consistent with the view that employers paid substantially more to agency help to avoid raising wages for their regular workers and to fill vacancies while they recruited workers for permanent positions. In low-skilled occupations, our evidence suggests that temporary help agencies facilitated the use of more “risky” workers by lowering their wages and benefits and the costs associated with turnover. The use of agency temporaries in both high- and low-skilled occupations reduced the pressure on companies to raise wages for existing employees, and thereby may have contributed to the stagnant wage growth and low unemployment observed in the 1990s.

Term dependence: Truncating the Bahadur Lazarsfeld expansion
Creators: name: Losee, Jr.,
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: The performance of probabilistic information retrieval systems is studied where differing statistical dependence assumptions are used when estimating the probabilities inherent in the retrieval model. Experimental results using the Bahadur Lazarsfeld expansion suggest that the greatest degree of performance increase is achieved by incorporating term dependence information in estimating Pr(d|rel) . It is suggested that incorporating dependence in Pr(d|rel) to degree 3 be used; incorporating more dependence information results in relatively little increase in performance. Experiments examine the span of dependence in natural language text, the window of terms in which dependencies are computed and their effect on information retrieval performance. Results provide additional support for the notion of a window of ± 3 to ± 5 to terms in width; terms in this window may be most useful when computing dependence.

description: In order to develop the quality of human resource in agriculture, a presence of agricultural extension workers – who were professional, creative, innovative, dan have global insight – in performing a agricultural extension that productive, effective, and efficient. The performance of agricultural extension workers had a strategic position in agricultural development. Thus, they had a lot of variety in job. The ability to perform their job were influenced by both internal and external factors. The internal factors include the characteristic of agricultural extension worker, educational background, and working experience that formed their behaviour. The external factors such as wages or rewards and career promotion of agricultural extension worker. When the rewards can meet their needs, a high level of task variety could be done. It is also expected that if the career or functional position being promoted, the performance of agricultural extension worker would also increase. Hence, career promotion may have influence to agricultural extension worker’s performance. The purposes of this research were to analyse both the direct and indirect impact of task variety, reward, and career promotion to performance. The research conducted through survey using interview and fill up questionnaire. Using the design of structural equation model of factors that influence the performance of agricultural extension worker, the data was analysed using model Structural Equation Models (SEM) with software Smart PLS 3.2.7 ver. Results of the research was: (1) there were a direct impact of task variety to performance, and indirect impact through career promotion and reward; (2) there were a direct impact of career promotion to performance, and indirect impact through task variety and reward; (3) there were a direct impact of reward to performance, and indirect impact through task variety and career promotion.

description: Inspired by the discovery of quantum hall effect and topological insulator, topological properties of classical waves start to draw worldwide attention. Topological non-trivial bands characterized by non-zero Chern numbers are realized with external magnetic field induced time reversal symmetry breaking or dynamic modulation. Due to the absence of Faraday-like effect, the breaking of time reversal symmetry in an acoustic system is commonly realized with moving background fluids, and hence drastically increases the engineering complexity. Here we show that we can realize effective inversion symmetry breaking and effective gauge field in a reduced two-dimensional system by structurally engineering interlayer couplings, achieving an acoustic analog of the topological Haldane model. We then find and demonstrate unidirectional backscattering immune edge states. We show that the synthetic gauge field is closely related to the Weyl points in the three-dimensional band structure.

description: We exploit a recent advance in the study of topological superconductors to propose a solution to the family puzzle of particle physics in the context of SO(18) (or more correctly, Spin(18)) grand unification. We argue that Yukawa couplings of intermediate strength may allow the mirror matter and extra families to decouple at arbitrarily high energies. As was clear from the existing literature, we have to go beyond the Higgs mechanism in order to solve the family puzzle. A pattern of symmetry breaking which results in the SU(5) grand unified theory with horizontal or family symmetry USp(4) = Spin(5) (or more loosely, SO(5)) leaves exactly three light families of matter and seems particularly appealing. We comment briefly on an alternative scheme involving discrete non-abelian family symmetries. In a few lengthy appendices we review some of the pertinent condensed matter theory.

Exploring Gender Distribution in Music Recommender Systems

description: Music Recommender Systems (mRS) are designed to give personalised and meaning-ful recommendations of items (i.e. songs, playlists or artists) to a user base, thereby reflecting and further complementing individual users’ specific music preferences. Whilst accuracy metrics have been widely applied to evaluate recommendations in mRS literature, evaluating a user’s item utility from other impact-oriented perspec-tives, including their potential for discrimination, is still a novel evaluation practice in the music domain. In this work, we centre our attention on a specific phenomenon for which we want to estimate if mRS may exacerbate its impact: gender bias. Our work presents an exploratory study, analyzing the extent to which commonly de-ployed state of the art Collaborative Filtering (CF) algorithms may act to further increase or decrease artist gender bias. To assess group biases introduced by CF, we deploy a recently proposed metric of bias disparity on two listening event datasets: the LFM-1b dataset, and the earlier constructed Celma’s dataset. Our work traces the causes of disparity to variations in input gender distributions and user-item pref-erences, highlighting the e˙ect such configurations can have on user’s gender bias after recommendation generation.

Text windows and phrases differing by discipline, location in document, and syntactic structure

Year: 1996

description: Knowledge of window style, content, location and grammatical structure may be used to classify documents as originating within a particular discipline or may be used to place a document on a theory versus practice spectrum. This distinction is also studied here using the type-token ratio to differentiate between sublanguages. The statistical signi cance of windows is computed, based on the the presence of terms in titles, abstracts, citations, and section headers, as well as binary independent (BI) and inverse document frequency (IDF) weightings. The characteristics of windows are studied by examining their within window density (WWD) and the S concentration (SC), the concentration of terms from various document  fields (e.g. title, abstract) in the fulltext. The rate of window occurrences from the beginning to the end of document fulltext differs between academic fi elds. Different syntactic structures in sublanguages are examined, and their use is considered for discriminating between speci c academic disciplines and, more generally, between theory versus practice or knowledge versus applications oriented documents.

description: Explosive energy release in the solar atmosphere is driven magnetically, but mechanisms triggering the onset of the eruption remain in debate. In the case of flares and CMEs, ideal or non-ideal instabilities usually occur in the corona, but direct observations and diagnostics there are difficult to obtain. To overcome this difficulty, we analyze observational signatures in the upper chromosphere or transition region, in particular, brightenings and dimmings at the feet of coronal magnetic structures. In this paper, we examine the time evolution of spatially resolved light curves in two eruptive flares, and identify a variety of tempo-spatial sequences of brightenings and dimmings, such as dimming followed by brightening, and dimming preceded by brightening. These brightening-dimming sequences are indicative of the configuration of energy release in the form of plasma heating or bulk motion. We demonstrate the potential of using these analyses to diagnose properties of magnetic reconnection and plasma expansion in the corona during the early stage of the eruption.

Expressive Performance Modeling in Polyphonic Flamenco and Jazz Guitar
Creators: name: Nou Plana, Ignasi
Publisher: name: Zenodo
Year: 2020

description: In musical performances, expressive models have been proposed in order to study the analysis and characterization of the deviations that a musician introduces when performing a musical piece. In this work, expressiveness in guitar performance is presented as a case of study. However, in guitar case studies, the ability to produce polyphonic sounds and its musical versatility, results on a variability of sounds, possessing significant challenges on the automatic transcription and on the analysis of the recorded data when building the dataset for the model. Data-driven methods have become increasingly popular in order to approach problems like guitar transcription and, datasets of labeled audio data are highly needed. This work proposes a system capable of collecting audio and MIDI annotations from guitar performances based on specific musical pieces, jazz and flamenco in this work. In particular, by recording guitar performances using a hexaphonic pickup, the system is able to, not only provide recording of the individual strings, but also to largely automate the annotation process of the expressive content of the music performance. Then a pretrained machine learning model is used in order to automatically generate music sequence excerpts based on the acquired data. Finally, di˙erent sets of data are presented in order to compare results and qualitative evaluations of the generated sequences are performed.

description: We show that a rank two finite group G admits a finite G-CW-complex X homotopy equivalent to a sphere, with rank one prime power isotropy, if and only if G does not p'-involve Qd(p) for any odd prime p. This follows from a more general theorem which allows us to construct a finite G-CW-complex by gluing together a given G-invariant family of representations defined on the Sylow subgroups of G.

description: We study the contribution of Galactic sources to the flux of astrophysical neutrinos recently observed by the IceCube Collaboration. We show that in the simplest model of homogeneous and isotropic cosmic ray diffusion in the Milky Way the Galactic diffuse neutrino emission consistent with $γ$-ray (Fermi-LAT) and cosmic ray data (KASCADE, KASCADE-Grande and CREAM) is expected to account for only $4\%-8\%$ of the IceCube flux above 60 TeV. Direct neutrino emission from cosmic ray-gas ($pp$) interactions in the sources would require an unusually large average opacity above 0.01. On the other hand, we find that the IceCube events already probe Galactic neutrino scenarios via the distribution of event arrival directions. Based on the latter, we show that most Galactic scenarios can only have a limited contribution to the astrophysical signal: diffuse Galactic emission ($\lesssim50\%$), quasi-diffuse emission of neutrino sources ($\lesssim65\%$), extended diffuse emission from the Fermi Bubbles ($\lesssim25\%$) or unidentified TeV $γ$-ray sources ($\lesssim25\%$). The arguments discussed here leave, at present, dark matter decay unconstrained.

Rabi oscillation in a quantum cavity: Markovian and non-Markovian dynamics

description: We investigate the Rabi oscillation of an atom placed inside a quantum cavity where each mirror is formed by a chain of atoms trapped near a one-dimensional waveguide. This proposal was studied previously with the use of Markov approximation, where the delay due to the finite travel time of light between the two cavity mirrors is neglected. We show that Rabi oscillation analogous to that obtained with high-finesse classical cavities is achieved only when this travel time is much larger than the time scale that characterizes the collective response of the atomic chain. Therefore, the delay must be taken into account and the dynamics of the problem is inherently non-Markovian. Parameters of interest such as the Rabi frequency and the cavity loss rate due to photon leakage through the mirrors are obtained.

description: The joint that pivots the jawbone with the skull, called the temporomandibular joint (TMJ), can sometimes become dislocated, leading to an inability to close the mouth. This dislocation can happen as a result of trauma, but is more commonly caused by problems in the joint and/or surrounding tissues, causing the joint to dislocate out of its socket when the mouth is opened excessively. It is most commonly seen in women between the ages of 20 and 30.This dislocation is very rare in children. Muhammad Khilji and Aftab Malik, of Sultan Qaboos University Hospital’s emergency department in Oman, reported the case of a 26-month-old girl with temporomandibular joint dislocation on both sides of the jaw in the Journal of Emergency Medicine Trauma & Acute Care.The child was brought to the emergency department presenting with drooling and an inability to close her mouth that had been on-going for two hours. Before the dislocation, she was fine and had eaten only two hours earlier. Clinical examination and X-rays revealed mild tenderness on both sides of the jaw, absence of injury marks, and anterior displacement of the lower jaw. Her vital signs were normal.To treat her, the child was sedated and the clinician manually returned the lower jaw into its joint. She was discharged once she fully regained consciousness and her ability to move her jaw and speak. She was bandaged to prevent excessive opening of her mouth and the clinicians explained to the mother how to prevent her daughter from excessively opening her mouth while yawning and crying.Prior to this report, only three other cases of young children (aged 10, 23 and 24 months) with bilateral TMJ dislocation appeared in the literature.“Bilateral TMJ dislocation is rare in children but it should be considered in children presenting in the [emergency department] with drooling of saliva, inability to close the mouth and preauricular [in front of the ears] swelling. Prompt reduction is necessary as delay increases muscle spasm necessitating anaesthesia for reduction,” the authors conclude.

Cumulant expansions for atmospheric flows

description: The equations governing atmospheric flows are nonlinear. Consequently, the hierarchy of cumulant equations is not closed. But because atmospheric flows are inhomogeneous and anisotropic, the nonlinearity may manifest itself only weakly through interactions of mean fields with disturbances such as thermals or eddies. In such situations, truncations of the hierarchy of cumulant equations hold promise as a closure strategy. We review how truncations at second order can be used to model and elucidate the dynamics of atmospheric flows. Two examples are considered. First, we study the growth of a dry convective boundary layer, which is heated from below, leading to turbulent upward energy transport and growth of the boundary layer. We demonstrate that a quasilinear truncation of the equations of motion, in which interactions of disturbances among each other are neglected but interactions with mean fields are taken into account, can capture the growth of the convective boundary layer even if it does not capture important turbulent transport terms. Second, we study the evolution of two-dimensional large-scale waves representing waves in Earth's upper atmosphere. We demonstrate that a cumulant expansion truncated at second order (CE2) can capture the evolution of such waves and their nonlinear interaction with the mean flow in some circumstances, for example, when the wave amplitude is small enough or the planetary rotation rate is large enough. However, CE2 fails to capture the flow evolution when nonlinear eddy--eddy interactions in surf zones become important. Higher-order closures can capture these missing interactions. The results point to new ways in which the dynamics of turbulent boundary layers may be represented in climate models, and they illustrate different classes of nonlinear processes that can control wave dissipation and momentum fluxes in the troposphere.

description: We show that for any graph $G$, by considering "activation" through the strong product with another graph $H$, the relation $α(G) \leq \vartheta(G)$ between the independence number and the Lovász number of $G$ can be made arbitrarily tight: Precisely, the inequality \[ α(G \times H) \leq \vartheta(G \times H) = \vartheta(G)\,\vartheta(H) \] becomes asymptotically an equality for a suitable sequence of ancillary graphs $H$. This motivates us to look for other products of graph parameters of $G$ and $H$ on the right hand side of the above relation. For instance, a result of Rosenfeld and Hales states that \[ α(G \times H) \leq α^*(G)\,α(H), \] with the fractional packing number $α^*(G)$, and for every $G$ there exists $H$ that makes the above an equality; conversely, for every graph $H$ there is a $G$ that attains equality. These findings constitute some sort of duality of graph parameters, mediated through the independence number, under which $α$ and $α^*$ are dual to each other, and the Lovász number $\vartheta$ is self-dual. We also show duality of Schrijver's and Szegedy's variants $\vartheta^-$ and $\vartheta^+$ of the Lovász number, and explore analogous notions for the chromatic number under strong and disjunctive graph products.

description: Stellar age estimates are often calculated by interpolating a star's properties in a grid of models. However, different model grids will give different ages for the same star. We used the open cluster M67 to compare four different model grids: DSEP, GARSTEC, MIST, and YREC. Across all model grids, age estimates for main sequence stars were consistently higher than the accepted age of M67, while age estimates for red giant stars were lower. We compared model-generated age and mass values to external constraints as an additional test of the reliability of each model grid. For stars near solar age and metallicity, we recommend using the DSEP model grid to estimate the ages of main sequence stars and the GARSTEC model grid for red giant stars.
