Implementation of Circular Economy Between Mining and Construction Sectors: A Promising Route to Achieve Sustainable Development Goals
Authors: El Machi Aiman , Hakkou Rachid 
Published: January 2024

AbstractThe mining sector is the largest solid waste producer in the world. Mining, mineral processing, and metallurgical activities generate more than 100 billion tons of waste per year in several forms. However, the current management of mine waste is still based on a linear system through its storage and landfilling. At the same time, growth of urbanization and industrialization induces the consumption of natural resources for building engineering in many countries. In this regard, the high demand for raw materials in the construction industry is becoming a worldwide issue. In order to tackle those challenges presented by the mining sector and the depletion of natural resources, innovative concepts are being developed. The circular economy concept is very beneficial, where mine waste can be considered as new raw materials for other applications, which will contribute not only to the reduction of natural resource consumption but also to the reduction of CO2 emissions. This chapter sheds light on the implementation of the circular economy concept with regard to the impact toward sustainable development goals, supported by examples of actual experiences around the world. Moreover, the importance of technical advances and the legislative aspect is discussed in order to underline its contribution to sustainable development.
Spectral flow of vortex shape modes over the BPS 2-vortex moduli space
Authors: Izquierdo A. Alonso , Fuertes W. Garcia , Manton N. S. , Guilarte J. Mateos 
Published: January 2024

Abstract
The flow of shape eigenmodes of the small fluctuation operator around BPS 2-vortex solutions is calculated, as a function of the intervortex separation 2d. For the rotationally-invariant 2-vortex, with d = 0, there are three discrete modes; the lowest is non-degenerate and the upper two are degenerate. As d increases, the degeneracy splits, with one eigenvalue increasing and entering the continuous spectrum, and the other decreasing and asymptotically coalescing with the lowest eigenvalue, where they jointly become the eigenvalue of the 1-vortex radial shape mode. The behaviour of the eigenvalues near d = 0 is clarified using a perturbative analysis, and also in light of the 2-vortex moduli space geometry.
Initial-final and initial-initial antenna functions for real radiation at next-to-leading order
Authors: Fox Elliot , Glover Nigel 
Published: January 2024

Abstract
The antenna subtraction method has achieved remarkable success in various processes relevant to the Large Hadron Collider. In Reference [1], an algorithm was proposed for constructing real-radiation antenna functions for electron-positron annihilation, directly from specified unresolved limits, accommodating any number of real emissions. Here, we extend this algorithm to build antennae involving partons in the initial state, specifically the initial-final and initial-initial antennae. Using this extended algorithm, we explicitly construct all NLO QCD antenna functions and compare them with previously extracted antenna functions derived from matrix elements. Additionally, we rigorously match the integration of the antenna functions over the initial-final and initial-initial unresolved phase space with the previous approach, providing an independent validation of our results. The improved antenna functions are more compact and reduced in number, making them more readily applicable for higher-order calculations.
NLO corrections to the deeply virtual meson production revisited: impact on the extraction of generalized parton distributions
Authors: Čuić Marija , Duplančić Goran , Kumerički Krešimir , Passek-K Kornelija 
Published: January 2024

Abstract
We revisit the next-to-leading order (NLO) perturbative QCD corrections for the deeply virtual meson production (DVMP) process, exploring its phenomenology both in isolation and in a multichannel fit combined with deeply virtual Compton scattering (DVCS). Our approach involves the conformal partial wave (CPaW) formalism, which allows for the straightforward inclusion of higher-order contributions and evolutionary effects. Our findings indicate that a description of the longitudinal component of the vector meson DVMP cross-section at high energies is achievable only at NLO within the standard collinear approach. Furthermore, we demonstrate a simultaneous description of DIS, DVCS, and DVMP processes, providing insights into the proton structure described at NLO by unique universal generalized parton distribution (GPD) functions.
Äußere Wendung – Chancen und Risiken
Authors: Bossung Verena , Andermatt Michelle 
Published: January 2024

ZusammenfassungDie äußere Wendung ist ein risikoarmes geburtshilfliches Manöver, bei dem der Fet manuell von einer Beckenend- oder Querlage in eine Schädellage gedreht wird. Sie wird in der Regel am wehenfreien Uterus 3–4 Wochen vor dem Entbindungstermin durchgeführt. Die Erfolgsrate variiert in der Literatur und liegt bei etwa 50 %. Sie wird von verschiedenen maternalen und fetalen Faktoren beeinflusst. Eine Wendung sollte bei Fehlen von Kontraindikationen jeder Schwangeren mit fetaler Beckenend- bzw. Querlage angeboten werden, um die Rate an vaginalen Geburten aus Schädellage zu steigern, Kaiserschnitte zu verhindern und damit die perinatale Morbidität und Mortalität zu senken. Die durchschnittliche Komplikationsrate beträgt 6 %, am häufigsten treten vorübergehende Auffälligkeiten der fetalen Herzfrequenz auf. Schwere Komplikationen sind selten. Eine äußere Wendung wird von den meisten Frauen gut toleriert. Tokolytika und analgetische Maßnahmen können unterstützend eingesetzt werden.
Understanding users’ responses to disclosed vs. undisclosed customer service chatbots: a mixed methods study
Authors: van der Goot Margot J. , Koubayová Nathalie , van Reijmersdal Eva A. 
Published: January 2024

AbstractDue to huge advancements in natural language processing (NLP) and machine learning, chatbots are gaining significance in the field of customer service. For users, it may be hard to distinguish whether they are communicating with a human or a chatbot. This brings ethical issues, as users have the right to know who or what they are interacting with (European Commission in Regulatory framework proposal on artificial intelligence. https://digital-strategy.ec.europa.eu/en/policies/regulatory-framework-ai, 2022). One of the solutions is to include a disclosure at the start of the interaction (e.g., “this is a chatbot”). However, companies are reluctant to use disclosures, as consumers may perceive artificial agents as less knowledgeable and empathetic than their human counterparts (Luo et al. in Market Sci 38(6):937–947, 2019). The current mixed methods study, combining qualitative interviews (n = 8) and a quantitative experiment (n = 194), delves into users’ responses to a disclosed vs. undisclosed customer service chatbot, focusing on source orientation, anthropomorphism, and social presence. The qualitative interviews reveal that it is the willingness to help the customer and the friendly tone of voice that matters to the users, regardless of the artificial status of the customer care representative. The experiment did not show significant effects of the disclosure (vs. non-disclosure). Implications for research, legislators and businesses are discussed.
Design of convex-shaped transparent heat spreaders for symmetrical cooling of a thin-disk laser crystal by mechanical pressing
Authors: Wolter Jan-Hinnerk , Voss Andreas , Graf Thomas , Abdou Ahmed Marwan 
Published: January 2024

AbstractWe present the design for a double-sided cooling of a thin-disk laser crystal using transparent, convex-shaped heat spreaders. The thermal contact between laser crystal and heat spreaders is established without bonding by solely applying an axial compressive force. A model of the contact behavior taking into account the deformation of the surfaces of the heat spreaders due to bending under mechanical loading is presented. The scope and accuracy of the modeling is verified by numerical simulations using the finite-element method. Based on the modeling, an exemplary design of the heat spreader which has been used for the first experimental demonstration of this concept is carried out. Based on the model, an almost ideal scalability of the heat transfer coefficient is predicted.
Evidence of pial synagiosis through ventriculoperitoneal shunt entry site in a patient who manifested Moyamoya syndrome later in childhood: A case report and historical perspective
Authors: AlEssa Awn , AlSahli Alaa , AlJared Tariq 
Published: January 2024

AbstractThe term Moyamoya , or “puff of smoke” in Japanese , was first used in 1969 by Suzuki and Takaku to describe the classical appearance of collateral blood vessels in response to progressive vascular stenosis of distal internal carotid artery (ICA). Such condition may result in various clinical presentations ranging from strokes to developmental delays. In order to cease the progression of such stenotic vasculopathy, several means of revascularization have been developed over the years. In this paper we present a case of a two-year-old girl with history of myelomeningocele repair and ventriculoperitoneal shunt insertion followed by manifestation of Moyamoya syndrome later in childhood as an evidence of revascularization through a burr hole. To our knowledge, this paper is the first of its kind to report such findings in one patient. Moreover, this paper provides a historical perspective on the development of different types of revascularization techniques.
A Grassmann manifold handbook: basic geometry and computational aspects
Authors: Bendokat Thomas , Zimmermann Ralf , Absil P.-A. 
Published: January 2024

AbstractThe Grassmann manifold of linear subspaces is important for the mathematical modelling of a multitude of applications, ranging from problems in machine learning, computer vision and image processing to low-rank matrix optimization problems, dynamic low-rank decompositions and model reduction. With this mostly expository work, we aim to provide a collection of the essential facts and formulae on the geometry of the Grassmann manifold in a fashion that is fit for tackling the aforementioned problems with matrix-based algorithms. Moreover, we expose the Grassmann geometry both from the approach of representing subspaces with orthogonal projectors and when viewed as a quotient space of the orthogonal group, where subspaces are identified as equivalence classes of (orthogonal) bases. This bridges the associated research tracks and allows for an easy transition between these two approaches. Original contributions include a modified algorithm for computing the Riemannian logarithm map on the Grassmannian that is advantageous numerically but also allows for a more elementary, yet more complete description of the cut locus and the conjugate points. We also derive a formula for parallel transport along geodesics in the orthogonal projector perspective, formulae for the derivative of the exponential map, as well as a formula for Jacobi fields vanishing at one point.
Understanding rate of return dynamics of cryptocurrencies: an experimental campaign
Authors: Koszewski Krzysztof , Mazumdar Somnath , Kumar Anoop S. 
Published: January 2024

AbstractIn recent years, cryptocurrencies have been considered as an asset by public investors and received much research attention. It is a volatile asset, thus predicting its prices is not easy due to the dependence on multiple external factors. Machine learning models are becoming popular for cryptocurrency price predictions, while also considering social media data. In this article, we analyze the rate of return of three cryptocurrencies (Bitcoin, Ether, Binance) from an investor point of view. We also consider three traditional external variables: S&P 500 stock market index, gold price, and volatility index. The rate of return prediction is based on three stages. First, we analyze the correlation between the cryptocurrency returns and the traditional external variables. Next, we focus on the influential social media variables (from Twitter, Reddit, and Wikipedia). Later, we use these variables to improve prediction accuracy. Third, we test how the standard time series models (such as ARIMA and SARIMA) and four machine learning models (such as RNN, LSTM, GRU and Bi-LSTM) predict one-day rate of return. Finally, we also analyze the risk of investing in each cryptocurrencies using value risk statistics. Overall, our result shows no correlation between cryptocurrency returns and three traditional external variables. Second, we found that overall LSTM model is the best, GRU is the second-best prediction model, while the impact of the social media variables varies depending on the cryptocurrencies. Finally, we also found that investment in gold offers better returns than cryptocurrency during Covid-19-like situations.

Abstract
Background
Invasive lobular carcinoma (ILC) is distinct from invasive ductal carcinoma (IDC) in terms of their hormonal microenvironments that may require different therapeutic strategies. We previously reported that selective estrogen receptor modulator (SERM) function requires F-box protein 22 (Fbxo22). Here, we investigated the role of Fbxo22 as a potential biomarker contributing to the resistance to endocrine therapy in ILC.

Methods
A total of 302 breast cancer (BC) patients including 150 ILC were recruited in the study. Fbxo22 expression and clinical information were analyzed to elucidate whether Fbxo22 negativity could be a prognostic factor or there were any correlations among clinical variables and SERM efficacy.

Results
Fbxo22 negativity was significantly higher in ILC compared with IDC (58.0% vs. 27.0%, P < 0.001) and higher in postmenopausal patients than premenopausal patients (64.1% vs. 48.2%, P = 0.041). In the ILC cohort, Fbxo22-negative patients had poorer overall survival (OS) than Fbxo22-positive patients, with 10-year OS rates of 77.4% vs. 93.6% (P = 0.055). All patients treated with SERMs, Fbxo22 negativity resulted in a poorer outcome, with 10-year OS rates of 81.3% vs. 92.3% (P = 0.032). In multivariate analysis regarding recurrence-free survival (RFS) in ILC patients, Fbxo22 status was independently predictive of survival as well as lymph node metastasis.

Conclusion
Fbxo22 negativity significantly impacts on survival in BC patients with IDC and ILC, and the disadvantage was enhanced among ILC postmenopausal women or patients treated with SERMs. The findings suggest that different therapeutic strategies might be needed according to the different histopathological types when considering adjuvant endocrine therapy.
Learning analytics dashboards are increasingly becoming about learning and not just analytics - A systematic review
Authors: Paulsen Lucas , Lindsay Euan 
Published: January 2024

AbstractThis systematic review explores the emerging themes in the design and implementation of student-facing learning analytics dashboards in higher education. Learning Analytics has long been criticised for focusing too much on the analytics, and not enough on the learning. The review is then guided by an interest in whether these dashboards are still primarily analytics-driven or if they have become pedagogically informed over time. By mapping the identified themes of technological maturity, informing frameworks, affordances, data sources, and analytical levels over publications per year, the review identifies an emerging trajectory towards student-focused dashboards. These dashboards are informed by theory-oriented frameworks, designed to incorporate affordances that supporting student learning, and realised through integration of more than just activity data from learning management systems – allowing the dashboards to better support students' learnings processes. Based on this emerging trajectory, the review provides a series of design recommendations for student-focused dashboards that are connected to learning sciences as well as analytics.
Academic reading as a grudging act: how do Higher Education students experience academic reading and what can educators do about it?
Authors: Mason Will , Warmington Meesha 
Published: January 2024

AbstractThis article examines Higher Education students’ experiences of academic reading as a grudging act: something that is performed reluctantly or half-heartedly, because it has to be done. Drawing on group interviews with 30 social science undergraduates, registered at a research-intensive UK university, we offer a reflexive thematic analysis of academic reading, experienced as ‘a struggle’, as ‘a chore’ and as ‘pointless’. Our analysis centres the experiential dimensions of reading, revealing how student orientations towards reading—and the teaching that surrounds it—can influence their practices. The article makes two original contributions to the developing literature about student reading experiences in Higher Education. First, by examining student accounts of reading through Bottero’s (2022) sociology of ‘grudging acts’, we extend what is known about the intersection between reading experiences and practices, raising important questions for educators in the social sciences and beyond. Second, by examining what educators can do in response to these challenges, we collate and extend existing guidance for educators that seek to support student engagement with academic reading in Higher Education.
Theoretical and empirical approach to how a professorship is organized in the German higher education system and how the organizational process works
Authors: Wilkesmann Uwe , Wagner Olga 
Published: January 2024

AbstractIn this article, we explore the question of how membership, hierarchy, rules, monitoring, and sanctions are used at German professorships to organize research. Using these five criteria of an organization from Ahrne and Brunsson (Organization, 18(1):83–104, 2011) as a theoretical pattern, we shed light on the meso-level of universities in the German higher education system—the professorship. It is at this level that the collaborative production of research is organized. We show which organizational mechanisms are necessary for this joint production process, how the practical implementation and interpretation of rules as an organizational process take place at the professorships, as well as various negotiations and sanctions. In the German higher education system, professors are the superiors of their academic staff. The professor decides on the hiring and renewal of employees and is the supervisor of doctoral candidates, who in the German higher education system are mostly employed as research assistants. To illustrate the characteristics of the criteria, we draw on empirical material from mixed-methods research, which made it possible to contrast and substantiate the special features of professorships in Germany from different perspectives and data.
The 1895 Ljubljana earthquake: source parameters from inversion of macroseismic data
Authors: Pettenati Franco , Jukić Ivana , Sirovich Livio , Cecić Ina , Costa Giovanni , Suhadolc Peter 
Published: January 2024

AbstractThe 14 April 1895 (Mw 6.1, in the area of Ljubljana, Slovenia) earthquake is still not fully understood. The aim of this work is to derive information about its source from the inversion of an updated dataset of intensities (evaluated with EMS-98). This was done via automatic non-linear geophysical inversion KF-NGA, which was performed using a Niching Genetic Algorithm and has been presented in other articles. The distribution of damage caused by this earthquake is not homogeneous and often shows significant intensity differences between neighbouring sites. Statistical analysis of the intensities, epicentral distances and geologic nature of the sites suggests some site effects. Nevertheless, the resulting solution is consistent with regional seismotectonics, i.e. an almost pure dip-slip mechanism: strike 282° ± 5°, dip 38° ± 7°, rake 86° ± 9° (± 180° because of the intrinsic ambiguity of the KF-NGA-inversion). Since the rake angle is close to 90°, there is an almost perfect ambiguity between the two planes of the focal mechanism. Therefore, our solution has a Dinaric direction and could be associated either with a fault plane that dips NE or with one that dips SW.

In this paper we consider a general random field (rf) Z that is a spectral rf of some stationary max-stable rf X and derive the properties of the corresponding Berman functions. In particular, we show that Berman functions can be approximated by the corresponding discrete ones and derive interesting representations of those functions which are of interest for Monte Carlo simulations presented in this article.
