Tam pam pam pam and mi – fa – sol: constituting musical instructions through multimodal interaction in orchestra rehearsals
Authors: Stoeckl Hartmut , Messner Monika 
Published: October 2021

Abstract
Using multimodal (inter)action/conversation analysis, the present contribution inventories the repertoire of higher-level actions that constitute musical instruction in orchestra rehearsals. The study describes the modal complexity of the instructional actions as built from a varied combination of speech, gesture, gaze, vocalizing and body posture/movement. A high modal intensity of speech and vocalizing is explained with recourse to their contextually useful modal reaches. While some modes, like vocalizing and body posture appear to be action-specific, others turn out to be pervasive default modes. Besides modal intensity, the study also attends to the transitioning between higher-level actions through gaze and the role of the score as frozen action. The analyses help demystify orchestra rehearsals as a special type of professional communicative interaction, which builds on a rich multimodal texture motivated by recurring instructional functions. The methodological rationale demonstrated will be suited to exploring the social variation of instructional interaction in orchestra rehearsals.
Frühbyzantinische Kreuzdiskurse des 6. und 7. Jahrhunderts und ihre Rezeption in Konstantinopel, Kappadokien und im Westen
Authors: Warland Rainer 
Published: October 2021

Abstract
The paper establishes connections between funerary art in the Eastern (Cappadocia) and the Western Mediterranean (Lombard kingdom in Northern Italy) during the seventh century. Jewelry pendants and gemstone decorations are also covered. The similarities of the image concepts suggest common design principles, with the cross as a symbol of the Son of Man when God returns on Judgment Day (Mt 24, 30). As celestial signs in the midst of stars and planets, these forms of the cross, which may also have influenced the Baiuvarian and Alemannic gold-leaf crosses, have a cosmic character. Under the sign of the concentric cross, according to Mt 24, 31, the angels gather together the elect (Christians) from the four directions of the world.
A New Edition of the De cerimoniis: No Longer a ‘geteiltes Dossier’?
Authors: Haldon John 
Published: October 2021

AbstractThis review article presents a brief survey of the new critical edition, translation and commentary of the important tenth-century Byzantine imperial treatise known as the De cerimoniis aulae byzantinae (on the ceremonial of the Byzantine court), a title ascribed to the text only in the 16th century. The edition offers an upto- date and highly accurate edition of the tenth century manuscripts through which the text has been transmitted and the detailed and rigorous commentary includes a complete historical and structural analysis of the two books into which the text is divided. In the course of their analysis, the editors arrive at a number of important new conclusions about the origins, intentions and structure of the text, the working methods of the emperor who commissioned it, and the aims and intentions of Basil the parakoimomenos, the person who commissioned the Leipzig manuscript, the chief surviving witness for the text. The 5 volumes of the publication represent a superb achievement by the team of French scholars under the original direction of Gilbert Dagron (†).
Lifting the voices of Spanish-speaking Kansans: a community-engaged approach to health equity
Authors: Showstack Rachel , Duque Silvia , Keene Woods Nikki , López Ana , Chesser Amy 
Published: October 2021

Abstract
An important component of social justice research is centering the voices of those individuals whose lives the research is intended to improve, not as subjects from whom researchers collect data but as active participants in a process of understanding and addressing issues of concern to the community. This ideal of community engagement slows the pace of dissemination of traditional social science or sociolinguistic scholarship but also allows scholars and community members to collaborate to identify and implement meaningful solutions to community problems. We describe a process of engagement of Spanish-speaking patients, interpreters, and healthcare providers in developing a health equity agenda for Spanish speakers in Kansas, grounded in a community-based participatory approach called Patient-Centered Outcomes Research. Stakeholders were engaged through sharing and amplifying their testimonios, stories that tied personal experiences of encountering language barriers in healthcare with calls to action, and they contributed to decisions about what to do with the stories and how to respond to the problems they identified. The result of our engagement process is the formation of a community-based team that has amplified the voices of Spanish-speaking patients and families to reach a range of audiences and responded to a number of evolving community needs. We provide recommendations for language researchers interested in pursuing community-engaged work and explore the possibilities for aligning such work with the expectations of academic institutions.
Dynamical behavior of fractionalized simply supported beam: An application of fractional operators to Bernoulli-Euler theory
Authors: Abro Kashif Ali , Atangana Abdon , Khoso Ali Raza 
Published: October 2021

Abstract
The complex structures usually depend upon unconstrained and constrained simply supported beams because the passive damping is applied to control vibrations or dissipate acoustic energies involved in aerospace and automotive industries. This manuscript aims to present an analytic study of a simply supported beam based on the modern fractional approaches namely Caputo-Fabrizio and Atanagna-Baleanu fractional differential operators. The governing equation of motion is fractionalized for knowing the vivid effects of principal parametric resonances. The powerful techniques of Laplace and Fourier sine transforms are invoked for investigating the exact solutions with fractional and non-fractional approaches. The analytic solutions are presented in terms of elementary as well as special functions and depicted for graphical illustration based on embedded parameters. Finally, effects of the amplitude of vibrations and the natural frequency are discussed based on the sensitivities of dynamic characteristics of simply supported beam.
Reduced graphene oxide coating on basalt fabric using electrophoretic deposition and its role in the mechanical and tribological performance of epoxy/basalt fiber composites
Authors: Mittal Garima , Lee Sang Woo , Rhee Kyong Y. 
Published: October 2021

Abstract
The interfacial bonding between the fiber and matrix plays a pivotal role in deciding the mechanical performance of fiber-reinforced composites. Basalt fibers, due to the absence of surface functional groups, do not interact potentially with the matrix and hence it leads to insufficient load-carrying capacity of the composite. Incorporating nanomaterials in the matrix and surface treatment of the reinforced fiber can improve the fiber–matrix interface. However, poor dispersion of nanomaterials and the complexity of surface treatment methods restrict their industrial applications. Coating nanomaterials directly onto the fiber surface has the potential to distribute the nanomaterials uniformly, along with strengthening the interfacial bonding between the fiber and matrix. In this study, graphene oxide was coated on the basalt fabric through electrophoretic deposition (EPD), and was further reinforced into the epoxy matrix. The aim of this study is to examine the effects of graphene oxide-coated basalt fiber using EPD on the mechanical and tribological performance of the composite. For comparison, epoxy/basalt composites and graphene oxide-coated epoxy/basalt composites were also prepared. Results showed that due to the improved fiber–matrix bonding and uniform distribution of graphene oxide, the coated basalt-reinforced composites showed better tensile strength and less wear loss.
Machine-learning-assisted microstructure–property linkages of carbon nanotube-reinforced aluminum matrix nanocomposites produced by laser powder bed fusion

Published: October 2021

Abstract
In this study, the cellular microstructural features in a subgrain size of carbon nanotube (CNT)-reinforced aluminum matrix nanocomposites produced by laser powder bed fusion (LPBF) (a size range between 0.5–1 μm) were quantitatively extracted and calculated from scanning electron microscopy images by applying a cell segmentation method and various image analysis techniques. Over 80 geometric features for each cellular cell were extracted and statistically analyzed using machine learning techniques to explore the structure–property linkages of carbon nanotube reinforced AlSi10Mg nanocomposites. Predictive models for hardness and relative mass density were established using these subgrain cellular microstructural features. Data dimension reduction using principal component analysis was conducted to reduce the feature number to 3. The results showed that even AlSi10Mg nanocomposite specimens produced using different laser parameters exhibited similar Al–Si eutectic microstructures, displaying a large difference in their mechanical properties including hardness and relative mass density due to cellular structure variance. For hardness prediction, the Extra Tress regression models showed a relative error of 2.47% for prediction accuracies. For the relative mass density prediction, the Decision Tress regression models showed a relative error of 1.42% for prediction accuracies. The results demonstrate that the developed models deliver satisfactory performance for hardness and relative mass density prediction of AlSi10Mg nanocomposites. The framework established in this study can be applied to the LPBF process optimization and mechanical properties manipulation of AlSi10Mg-based alloys and other additive manufacturing newly designed alloys or composites.
Migration, Exile, and Homecoming in the Book of Ruth
Authors: Anzi Achia 
Published: October 2021

Abstract
My article examines various artworks from Europe and Israel that portray and are inspired by the Book of Ruth. While in Jewish sources such as the Talmud (Yevamot 47b) Ruth is seen as an immigrant and a convert to Judaism, European artists since the seventeenth century highlighted different episodes and aspects of the biblical story that suited their social, political, and religious worldviews. Notably, the expansion of colonialism during the nineteenth century transformed the depictions of Ruth. While in the canvases of painters such as Pieter Lastman and Jan Victors Ruth is depicted as a model of religious identification, in the paintings of Joseph Anton Koch and Francesco Hayez she epitomises “oriental” otherness. Furthermore, while early European painters underscore the immigration of Ruth, Hayez represents Ruth as a dweller of the “East.” Zionist artists were influenced by European traditions of depicting the Book of Ruth but developed a unique fusion between strategies of identification and differentiation. Artists such as Ze’ev Raban (1890–1970) portrayed the story of Ruth as both ancient and contemporary, while imitating and appropriating Palestinian tropes in order to imagine the Zionist narrative of homecoming. The contemporary Israeli artist Leor Grady (b. 1966), on the other hand, addresses questions of immigration and homecoming while exploring the Book of Ruth in his solo exhibition Bethlehem (2019, Tel Aviv). While Raban’s illustrations ignore the Jewish experience of exile, Grady’s oeuvre epitomises what the Israeli historian Amnon Raz-Krakotzkin sees as “exile within sovereignty.” Instead of recounting a linear historical narrative that begins with exile and culminates with the return to the Promised Land, Grady underscores that every return is also a departure and every departure a return. In this manner, Grady foregrounds the voices silenced by Zionist historiography and challenges the exclusion of the Palestinian narrative.
Hopf bifurcation analysis for liquid-filled Gyrostat chaotic system and design of a novel technique to control slosh in spacecrafts
Authors: Sabir Muhammad , Ahmad Salman , Marwan Muhammad 
Published: October 2021

AbstractIn this article, a fuel tank is coupled with gyrostat in a moving spacecraft to discuss its dynamical behaviour and bringing stability in velocity vectors. Parametric study is performed using Hopf bifurcation to find the bifurcation parameter for a considered mechanical model. Furthermore, a region is constructed in which negligible limit cycles appear around unstable spirals for angular momentum greater than bifurcation point. Based on local dynamical analysis, trajectories of angular velocities are observed with respect to damping constant, which is formulated in the form of bifurcation parameter. Moreover, a controller is designed in this article for considered dynamical system by achieving global stability, with the help of Lyapunov theory, into the spacecraft coupled with filled fuel tank, and their results are compared with effective spacecraft control strategies to observe the effectiveness of our proposed control technique. Finally, in presented research, numerical simulations are performed using MATLAB for validation of analytical results, which the authors have achieved for Hopf bifurcation and designed controller.
Prediction of stock index of two-scale long short-term memory model based on multiscale nonlinear integration
Authors: Tang Decai , Pan Zhiwei , Bethel Brandon J. 
Published: October 2021

Abstract
Although the prediction of stock prices and analyses of their returns and risks have always played integral roles in the stock market, accurate predictions are notoriously difficult to make, and mistakes may be devastatingly costly. This study attempts to resolve this difficulty by proposing and applying a two-stage long short-term memory (LSTM) model based on multi-scale nonlinear integration that considers a diverse array of factors. Initially, variational mode decomposition (VMD) is used to decompose an employed stock index to identify the different characteristics of the stock index sequence. Then, an LSTM model based on the multi-factor nonlinear integration of overnight information is established in a second stage. Finally, the joint VMD-LSTM model is used to predict the stock index. To validate the model, the Shanghai Composite, Nikkei 225, and Hong Kong Hang Seng indices were analyzed. Experiments show that, by comparison, the prediction effect of the mixed model is better than that of a single LSTM. For example, RMSE, MAE and MAPE of the mixed model of the Shanghai Composite Index are 4.22, 4.25 and 0.2 lower than the single model respectively. The RMSE, MAE and MAPE of the mixed model of the Nikkei 225 Index are 47.74, 37.21 and 0.17 lower than the single model respectively, and the RMSE, MAE and MAPE of the mixed model of the Hong Kong Hang Seng Index are 37.88, 25.06 and 0.08 lower than the single model respectively.

Authors: Alkatout Ibrahim , Wedel Thilo , Pape Julian , Possover Marc , Dhanawat Juhi 
Published: October 2021

Abstract
A prerequisite for nerve-sparing pelvic surgery is a thorough understanding of the topographic anatomy of the fine and intricate pelvic nerve networks, and their connections to the central nervous system. Insights into the functions of pelvic nerves will help to interpret disease symptoms correctly and improve treatment. In this article, we review the anatomy and physiology of autonomic pelvic nerves, including their topography and putative functions. The aim is to achieve a better understanding of the mechanisms of pelvic pain and functional disorders, as well as improve their diagnosis and treatment. The information will also serve as a basis for counseling patients with chronic illnesses. A profound understanding of pelvic neuroanatomy will permit complex surgery in the pelvis without relevant nerve injury.
The role of mitophagy during oocyte aging in human, mouse, and Drosophila: implications for oocyte quality and mitochondrial disease
Authors: Cox Rachel T , Poulton Joanna , Williams Suzannah A 
Published: October 2021

There is a worldwide trend for women to have their first pregnancy later in life. However, as oocyte quality declines with maternal aging, this trend leads to an increase in subfertility. The cellular mechanisms underlying this decline in oocyte competence are poorly understood. Oocyte mitochondria are the subcellular organelles that supply the energy that drives early embryogenesis, and thus their quality is critical for successful conception. Mitochondria contain their own DNA (mtDNA) and mutations in mtDNA cause mitochondrial diseases with severe symptoms, such as neurodegeneration and heart disease. Since mitochondrial function declines in tissues as humans age accompanied by an accumulation of mtDNA mutations, mtDNA is implicated as a cause of declining oocyte quality in older mothers. While this mutation load could be caused by declining accuracy of the mitochondrial replisome, age-related decline in mitochondrial quality control likely contributes, however knowledge is lacking. Mitophagy, a cellular process which specifically targets and recycles damaged mitochondria may be involved, but studies are scarce. And although assisted reproductive technologies can help older mothers, how these techniques affect the mechanisms that regulate mitochondrial and oocyte quality have not been studied. With the long-term goal of understanding the molecular mechanisms that control mitochondrial quality in the oocyte, model systems including Drosophila and mouse as well as human oocytes have been used. In this review, we explore the contribution of mitophagy to oocyte quality and the need for further systematic investigation in oocytes during maternal aging using different systems.

Lay summary
Mitochondria are small parts of cells called organelles that generate the chemical energy needed for life. Hundreds of thousands of mitochondria in the developing eggs of the mother support the initial growth and development of the fertilized egg. However, due to increasingly diminished function over time, mitochondria generate less energy as we age, posing real problems for older women considering pregnancy. It is possible that this declining energy could be responsible for declining fertility as women age. Energy may decline because mitochondria fail and the cell’s way of keeping them healthy become less efficient as we age. This review summarizes what is known about mitochondrial quality control in developing eggs as they age. In the future, understanding how the best mitochondria are selected and maintained in the egg, and hence the future baby, may enable older women with or without mitochondrial problems, to have healthy children.
Stroke és a cardiorespiratoricus fittség
Authors: Apor Péter 
Published: October 2021

Összefoglaló. A fizikai inaktivitás a cardiovascularis betegségek –
így a stroke – jelentős kockázati tényezője. A rendszeres testmozgás növeli az
aerob kapacitást, a cardiorespiratoricus fittséget – ezzel csökkenti a
cardiovascularis betegségek, köztük a stroke kockázatát. Az elmúlt évek azon
vizsgálataiból idéz a közlemény, amelyek a fizikai aktivitás, a
cardiorespiratoricus teljesítőképesség szerepét ismertetik a stroke elsődleges
és másodlagos prevenciójában. Említésre kerülnek az aerob kapacitás mérésének
módszerei. A nemzetközi tapasztalatok azt igazolják, hogy magas
cardiorespiratoricus fittség esetén közel harmadával csökken a stroke
előfordulása. A WHO ajánlása mindenkinek a heti legalább 150 percnyi
mérsékelten-közepesen meglihegtető testi tevékenység – ez a leggyakoribb
krónikus betegségek ellen bizonyos védelmet ad. Orv Hetil. 2021; 162(39):
1567–1572.
Summary. Physical inactivity is a significant risk for
cardiovascular diseases, even for stroke. Regular physical activity improves
aerobic capacity, cardiorespiratory fitness, aerob endurance performance
(synonyms), diminishing the risk of cardiovascular diseases as well as the risk
of stroke. We refer to previous literature data from the past two decades
demonstrating the beneficial role of the higher aerob fitness in the primary and
secondary prevention of stroke. Relevant methods of measuring aerob performance
have been described previously. In the case of optimal aerobic fitness, the
occurrence of stroke is lower by a third according to international experience.
WHO advices moderate-medium intensity physical activity of minimum 150 minutes
per week, which carries significant protection against the majority of chronic
cardio-metabolic diseases. Orv Hetil. 2021; 162(39): 1567–1572.
