Authors: Abolmasov Biljana , Marjanović Miloš , Đurić Uroš , Krušić Jelka 
Published: December 2023

AbstractThe University of Belgrade, Faculty of Mining and Geology has been involved in landslide risk reduction activities at the national, regional, and site-specific levels in Serbia for decades. Since 2011 the Faculty has had several activities closely connected with the International Consortium on Landslides, including the International Programme on Landslides Projects 181, 210 and 248, as well as World Centre of Excellency (WCoE) from 2017. In the past decade the Faculty of Mining and Geology was involved in several national, regional and local projects funded by the People of Japan, UNDP and The World Bank on landslide risk reduction in Serbia, Bosnia and Herzegovina and North Macedonia. They all closely involved many stakeholders from national to local authorities including Ministries, Local Self Governments, Public Enterprises, Emergency Offices and Civil Protection units. In this report, the activities of WCoE for national and local authorities on landslide risk reduction will be presented.
Remedial Measures Impact on Slope Stability and Landslide Occurrence in Small-Scale Slope Physical Model in 1 g Conditions

Published: December 2023

AbstractPhysical modelling of landslides by analysing the behaviour of small-scale landslide models subjected to artificial rainfall can be divided into modelling under 1 g conditions and under increased acceleration (ntimes gravity) in a centrifuge. Physical modelling of landslide initiation began in 1970s in Japan on scaled natural slope models and after initial experiences with field and laboratory research, the small-scale landslide modelling has found a wide application around the world in different aspects of landslide investigations, analysing different types of landslides, different types of slope materials and landslide movements. The main task of landslide physical modelling is research of initiation, motion and accumulation of fast flow-like slides caused by infiltration of surface water or by shaking on a shaking table. Studies that have included landslide mitigation measures into small-scale physical models are rare and have not established correlations with a behaviour of on-site mitigation constructions. This paper discusses the behaviour of small-scale slope models supported by remedial measures under artificial rain in 1 g loading conditions. Models of slope built of different materials, with and without applied remedial measures (gravity retaining wall, gabion wall, pile wall) were exposed to identical intensities of artificial rainfall. The results of the simulations indicated that the slopes supported by remedial measures retained stability of the slope in the same conditions in which the sandy slope collapsed, as well as under significantly prolonged precipitations. At the end of the simulations, significantly higher rainfall intensities were applied to the supported slopes, exceeding the infiltration capacity of the slope material and affecting surface runout. The combination of surface erosion and saturation of superficial layer of a slope caused initiations of flow processes, while complete saturation of a slope when ground water level reached slope surface caused forming of a surface of rupture and consequently movements of the formed landslide body. The data obtained from the geodetic and geotechnical monitoring system enabled understanding of the overall process of rainfall infiltration and soil strength reduction to the development of the surface of rupture in a slope.
Introduction: Universities and the Matter of Mattering
Authors: Mattsson Pauline , Perez Vico Eugenia , Salö Linus 
Published: December 2023

AbstractIn this introductory chapter, we provide insights into the debates that inspired this volume. Our aim is to extend the boundaries of the concept societal interaction and discuss the conditions for universities to undertake such endeavors. Within this context, we introduce the matter of “mattering” which serves as the central theme that runs through this volume. Mattering, we posit, can be comprehended through three key concepts: collaboration, engagement, and impact. We outline how each concept contributes to an increasing understanding of the manifold ways in which mattering can be grasped and achieved. Furthermore, we provide an overview of the coherent set of individual chapters that, separately or jointly, deal with the three concepts. Through these chapters, this volume aims to make a valuable addition to the evolving literature that explores how universities can expand their impact beyond conventional higher education missions. Collectively, these chapters cover the context of the mattering of universities and draw on various empirical data sources, mainly from Sweden but also internationally. Within this compilation of inquiries, we shed light on the multifaceted impact of universities on societies, exploring the mechanisms, contexts, and temporal dimensions of their contributions to advancing knowledge and addressing societal challenges.
Valorizing the Humanities: Impact Stories, Acting Spaces, and Meandering Knowledge Flows
Authors: Perez Vico Eugenia , Sörlin Sverker , Hanell Linnea , Salö Linus 
Published: December 2023

AbstractDespite its proven societal value, humanities knowledge tends to be marginalized in research policy; this has been a topic of debate for some time. In this chapter, we focus on the valorization of humanities knowledge, with the aim of comprehending the way this process engenders societal impact. We argue that historical impact stories offer an effective methodological approach for a deeper understanding of such valorization and its subsequent impact. Drawing on three humanities research cases from Sweden, we propose that valorization and impacts of humanities knowledge should be seen as processual and as influenced by societal actors who determine the premises and condition the somewhat unpredictable nature of such impacts. We introduce two concepts: (i) acting space, which involves access to collaborators, audiences, and channels that enable knowledge valorization, and (ii) meandering knowledge flows, which provides insight into the uneven and hard-to-predict nature of valorization. Through these concepts, we wish to provide a better and more nuanced understanding of how knowledge valorization in the humanities unfolds. By doing so, we hope to support humanities scholars to find ways of articulating their own modes of mattering.
Engaging in Societal Collaboration Through Reflexivity: Experiences from a Cross-Disciplinary Pilot Course for Faculty
Authors: Jonsson Anna , Perez Vico Eugenia , Politis Diamanto 
Published: December 2023

AbstractThere is limited understanding of how education initiatives geared toward faculty and support staff can foster a capacity for long-term and integrated societal engagement and collaboration within higher education institutions. Using the experiences from a cross-disciplinary pilot course in Sweden, the current study aims to identify features that explicate how skills and academic rigor for engaging in societal collaboration can be developed toward a “reflexive scholarship of societal collaboration.” Based on a case study of the course, we identify the need for (i) theoretical orientation, (ii) collective reflections among diverse participants, and (iii) application of gained knowledge in real-world contexts. Building on the experiences from the pilot course, we explore and discuss the participants’ reflections on how their partaking in the course may support a reflexive scholarship of societal collaboration. Our study is relevant to managers and policymakers interested in nurturing long-term and integrated collaborations between academia and various societal actors.
Governing by Organizing: The Context of Universities in Sweden
Authors: Bjare Ulrika 
Published: December 2023

AbstractThe chapter provides an overview of how three significant educational reforms, dating back to the late 1970s, have shaped the policy agenda for higher education and research in Sweden. The concept of metagovernance through governing by organizing is applied as a conceptual framework for comprehending the steering mechanisms inherent in these three university reforms. The reforms serve as illustrations, revealing that the state’s governance capacity is strongly contingent upon organizational factors. The application of organizational theory helps uncover new aspects of the state’s role and governance within the domain of higher education and research policy. This mode of steering frequently manifests as the establishment of conditions or the facilitation of capacities for steering mechanisms within specific organizational structures, aimed at achieving policy objectives. The objectives are formulated around various, and often ambivalent, ideas of how to enforce and advance the means through which universities can matter to other parts of society and national development.
Responsive Research Quality Articulations of the Humanities
Authors: Müller Klara 
Published: December 2023

AbstractThis chapter describes the development of research quality articulations. It shows how articulations of research quality in Swedish humanities policy spaces have changed between 1980 and 2010. The study demonstrates an increased presence and diversity of quality articulations in the spaces studied. However, different contexts produced different outcomes. Co-production between science and policy articulations resulted in what this study terms responsive quality articulations, neither internal nor external in nature. These findings have implications for how research quality can be studied and conceptualized, as well as for the history of humanities in Sweden. An understanding of how research quality has developed responsively complicates the commonly used narratives that depict the humanities as either passive or reactive to policy changes. Therefore, the findings offer an alternative narrative to the trope of a “crisis” in the humanities, by highlighting how humanities scholars influenced research policy in articulating quality. It shows that negotiations over research quality during these 30 years have been more complex than previously acknowledged, in turn allowing us to reassess current understandings of research quality in the humanities.

We present the three-loop calculations of the nonrelativistic QCD (NRQCD) current renormalization constants and corresponding anomalous dimensions, and the matching coefficients for the spatial-temporal tensor and spatial-spatial axial-tensor currents with two different heavy quark masses. We obtain the convergent decay constant ratio up to the next-to-next-to-next-to-leading order (N3LO) for the S-wave vector meson $$ {B}_c^{\ast } $$

The Källén-Lehmann representation in de Sitter spacetime
Authors: Loparco Manuel , Penedones João , Salehi Vaziri Kamran , Sun Zimo 
Published: December 2023

Abstract
We study two-point functions of symmetric traceless local operators in the bulk of de Sitter spacetime. We derive the Källén-Lehmann spectral decomposition for any spin and show that unitarity implies its spectral densities are nonnegative. In addition, we recover the Källén-Lehmann decomposition in Minkowski space by taking the flat space limit. Using harmonic analysis and the Wick rotation to Euclidean Anti de Sitter, we derive an inversion formula to compute the spectral densities. Using the inversion formula, we relate the analytic structure of the spectral densities to the late-time boundary operator content. We apply our technical tools to study two-point functions of composite operators in free and weakly coupled theories. In the weakly coupled case, we show how the Källén-Lehmann decomposition is useful to find the anomalous dimensions of the late-time boundary operators. We also derive the Källén-Lehmann representation of two-point functions of spinning primary operators of a Conformal Field Theory on de Sitter.
An algebraic formula for two loop renormalization of scalar quantum field theory
Authors: Jenkins Elizabeth E. , Manohar Aneesh V. , Naterop Luca , Pagès Julie 
Published: December 2023

Abstract
We find a general formula for the two-loop renormalization counterterms of a scalar quantum field theory with interactions containing up to two derivatives, extending ’t Hooft’s one-loop result. The method can also be used for theories with higher derivative interactions, as long as the terms in the Lagrangian have at most one derivative acting on each field. We show that diagrams with factorizable topologies do not contribute to the renormalization group equations. The results in this paper will be combined with the geometric method in a subsequent paper to obtain the counterterms and renormalization group equations for the scalar sector of effective field theories (EFT) to two-loop order.
Shrinking the Warm Little Inflaton
Authors: Ferraz Paulo B. , Rosa João G. 
Published: December 2023

Abstract
We show that warm inflation can be successfully realized in the high temperature regime through dissipative interactions between the inflaton and a single fermionic degree of freedom, provided that the latter’s mass is an oscillatory function of the inflaton field value. We demonstrate, in particular, that despite the consequent large amplitude oscillations of the eta slow-roll parameter, their effect is, on average, sufficiently suppressed to allow for a slow-roll trajectory. In addition, we demonstrate that, even though this also induces a parametric resonance that amplifies inflaton perturbations, this has a negligible effect on CMB scales in the relevant parametric range. Hence, the “Warm Little Inflaton” scenario can be realized with one less fermionic degree of freedom and no need of imposing an additional discrete interchange symmetry.

Press-Fit-Hybrid®-Technik in der Rekonstruktion des vorderen Kreuzbands
Authors: Volz R. , Borchert G. H. , Neumann-Langen M. V. 
Published: December 2023

Zusammenfassung
Hintergrund
Das Ziel der Rekonstruktion des vorderen Kreuzbands (VKB) ist die möglichst anatomische und biologische Wiederherstellung der Kniefunktion, um ein Fortschreiten degenerativer Gelenkveränderungen zu vermeiden. Die Press-Fit-Hybrid®(PFH)-Technik ist eine biologische Alternative zur konventionellen Interferenzschrauben(IF)-Technik und kann zur Fixation von Hamstringsehnen- bzw. rein tendinösen Quadrizepssehnentransplantaten angewandt werden.

Fragestellung
Führt die PFH-Technik zu einer geringeren Rerupturrate und zu weniger sekundären Meniskusverletzungen im Vergleich zur IF-Technik?

Material und Methoden
Retrospektive Auswertung von 200 Patienten mit VKB-Rekonstruktionen (100 Patienten in IF-Technik, 100 Patienten in PFH-Technik). Bei der PFH-Technik werden mit einer Diamant-Hohlfräse zeitgleich ein Tunnel und ein Knochenzylinder generiert. Die Herstellung optimaler Press-Fit-Konditionen durch die Anwendung standardisierter Dilatationsschritte erlaubt eine Press-Fit-Fixierung mittels femoralen und tibialen Knochenzylindern sowie zusätzlich femoral mit einem justierbaren Fixationsbutton und tibial mit einer Ankerschraube. Es wurden die Rerupturrate und die sekundären Meniskusverletzungen postoperativ sowie klinische Stabilitäts- und Bewegungsumfänge ermittelt.

Ergebnisse und Schlussfolgerung
Die Rerupturrate betrug in der IF-Gruppe 9 % (n = 9, nach 5,3 Jahren) und in der PFH-Gruppe 4 % (n = 4, nach 4,2 Jahren; p < 0,0001). Postoperative Meniskusverletzungen fanden sich 9 % in der IF-Gruppe und 6 % (p = 0,59276) in der PFH-Gruppe. Postoperativ war die klinische Funktion signifikant besser in der PFH-Gruppe, die Gelenkstabilität war in beiden Gruppen gleich. Die PFH-Technik erzielt im Vergleich mit der IF-Technik eine geringere Rerupturrate und eine geringere Rate sekundärer Meniskusläsionen.
THB-Diff: a GPU-accelerated differentiable programming framework for THB-splines
Authors: Moola Ajith , Balu Aditya , Krishnamurthy Adarsh , Pawar Aishwarya 
Published: December 2023

AbstractWe have developed a differentiable programming framework for truncated hierarchical B-splines (THB-splines), which can be used for several applications in geometry modeling, such as surface fitting and deformable image registration, and can be easily integrated with geometric deep learning frameworks. Differentiable programming is a novel paradigm that enables an algorithm to be differentiated via automatic differentiation, i.e., using automatic differentiation to compute the derivatives of its outputs with respect to its inputs or parameters. Differentiable programming has been used extensively in machine learning for obtaining gradients required in optimization algorithms such as stochastic gradient descent (SGD). While incorporating differentiable programming with traditional functions is straightforward, it is challenging when the functions are complex, such as splines. In this work, we extend the differentiable programming paradigm to THB-splines. THB-splines offer an efficient approach for complex surface fitting by utilizing a hierarchical tensor structure of B-splines, enabling local adaptive refinement. However, this approach brings challenges, such as a larger computational overhead and the non-trivial implementation of automatic differentiation and parallel evaluation algorithms. We use custom kernel functions for GPU acceleration in forward and backward evaluation that are necessary for differentiable programming of THB-splines. Our approach not only improves computational efficiency but also significantly enhances the speed of surface evaluation compared to previous methods. Our differentiable THB-splines framework facilitates faster and more accurate surface modeling with local refinement, with several applications in CAD and isogeometric analysis.

AbstractPurposeTo reach a consensus among obstetrics and gynecology experts on the effects of micronutrient supplementation on fertility and pregnancy to aid clinicians in decision-making and create a unified approach to managing micronutrient deficiencies in women, by performing a modified Delphi study.MethodsA three-round modified Delphi process was conducted among a Delphi panel of 38 Egyptian experts to define recommendations regarding the role of supplementation on fertility and pregnancy in women of reproductive age. A literature review was performed and supporting evidence was graded to help guide the recommendations based on available evidence.ResultsA total of 62 statements were developed for discussion and voting. Out of the 62 statements, 60 statements reached expert consensus. Statements were divided into two domains. The first domain discussed the role of supplementation in fertility: optimizing natural fertility, polycystic ovary syndrome (PCOS), in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI), unexplained infertility, and endometriosis, whereas the second domain was concerned with the role of supplementation in pregnancy during the prenatal, antenatal, and postnatal periods.ConclusionIn this work, a modified Delphi methodology was implemented to reach a consensus on the use of micronutrient supplementation in women of reproductive age. These recommendations can help clinicians in their practice, guide future research, and identify gaps in the market for the pharmaceutical industry. This clinical guidance can be extrapolated to similar communities.
