Novel small-size seismic metamaterial with ultra-low frequency bandgap for Lamb waves
Authors: Shi Nannan , Liu Han , Zhao Liutao 
Published: August 2024

Abstract
Seismic metamaterials (SMs) possess bandgap characteristics, enabling effective attenuation of seismic waves within a specific frequency range. However, small-sized SMs typically struggle to achieve a wide low-frequency bandgap. This paper proposes four types of SMs. The dispersion curves of these models were analyzed, and their vibration modes were studied to elucidate the bandgap mechanism. To investigate the influence of structural parameters on the bandgap, geometric variables are analyzed. Subsequently, the spectrum and acceleration time history curves of Lamb waves in a finite SM system are analyzed to verify the bandgap's authenticity. The designed structure exhibits a bandgap ranging from 1.24 Hz to 16.86 Hz, with a relative bandwidth as high as 172.6% and over 96% maximum vibration displacement attenuation of the El Centro seismic wave. The designed SMs effectively cover the 2 Hz seismic peak spectrum that leads to structural damage. They possess ideal relative bandwidth and excellent isolation performance, further advancing the engineering application of SMs.
The Market Life of Japanese Literature in Postwar America: Knopf, Translation, and the Archives of Cultural Commerce
Authors: Hurley Brian 
Published: August 2024

Abstract
This article examines the aesthetic and economic forms of judgment that guided the Japanese literature translation program at the American publisher Alfred A. Knopf Inc. in the 1950s—1970s. During these years, the editor Harold Strauss coordinated Knopf’s ambitious translation program that made dozens of recently written Japanese novels available in English to an American audience. This article provides a fresh perspective on Knopf’s well-known Japanese literature translation program by understanding it to be an illuminating case study that reveals how the practical business of cultural commerce mixes aesthetic and economic modes of valuation, producing provocative connections that link what might otherwise seem to be the antagonistic realms of art and the market. Guided by documents held in the Knopf corporate archive, the article shows how the aesthetics of modern Japanese literature and the economics of publishing each encountered the other in the transactional territory of translation.
Between History and Phantasmagoria: Critical Nostalgic Lyricism in Alai's Poetry and Short Fiction
Authors: Li Dian 
Published: August 2024

Abstract
In his poetry and fiction, Alai creates a historiography of Eastern Tibet replete with the grandeur and magnificence of the past occasionally interposed with some oppressive cultural practices. It is a historiography motivated and energized by nostalgic lyricism, which helps locate and construct a symbolic Tibetan ethnicity. This article proposes that Alai's nostalgic lyricism critically reflects on the inversion of loss and the compensation of lack, thus articulating alternatives against the discontent of the present. In so doing, Alai formulates a minority position against the forces of deterministic historicism and discourse of linear modernity that have constantly placed the minority subject in modern China under threat of erasure.
The Undocumented and Archipelagic Universal in Miko Revereza'sNo Data Plan
Authors: Suarez Harrod J. 
Published: August 2024

AbstractThis article argues that the archipelagic serves as a potent cultural geographic figure challenging resurgent nationalisms in two specific ways. First, it enables us to explore a simultaneous proximity and distance in cultural politics; second, it leads us astray from the conceptual binary that would insist that it is simply other to the nation. In doing so, it arrives at a universalism that is fundamentally differentiated. The essay pursues this framework through an analysis of Miko Revereza's recent documentary film, No Data Plan (2019), which explores Revereza's undocumented status in the United States, and its repertoire of aesthetic techniques, including its erratic and partial framing of his train journey across the country as well as its disjointed soundtrack. Above all, the essay draws attention to the film's use of captions, through which Revereza's mother's story is narrated, and which cannot be reconciled with the rest of the film. Her captions hover in proximity to the filmic diegesis without seeking presence, rejecting a dialectical engagement with a presence in the film that stands in for a documented presence in the nation. By choosing instead to “speak nearby,” she disturbs conventional cultural political logics and dwells within an archipelagic relation to the film, her son, and the world.
Gearing in a hydrostatic skeleton: the tube feet of juvenile sea stars (Leptasterias sp.)
Authors: Po Theodora , Carrillo Andres , McKee Amberle , Pernet Bruno , McHenry Matthew J. 
Published: August 2024

ABSTRACT
Hydrostatic skeletons, such as an elephant trunk or a squid tentacle, permit the transmission of mechanical work through a soft body. Despite the ubiquity of these structures among animals, we generally do not understand how differences in their morphology affect their ability to transmit muscular work. Therefore, the present study used mathematical modeling, morphometrics, and kinematics to understand the transmission of force and displacement in the tube feet of the juvenile six-rayed star (Leptasterias sp.). An inverse-dynamic analysis revealed that the forces generated by the feet during crawling primarily serve to overcome the submerged weight of the body. These forces were disproportionately generated by the feet at more proximal positions along each ray, which were used more frequently for crawling. Owing to a combination of mechanical advantage and muscle mass, these proximal feet exhibited a greater capacity for force generation than the distal feet. However, the higher displacement advantage of the more elongated distal feet offer a superior ability to extend the feet into the environment. Therefore, the morphology of tube feet demonstrates a gradient in gearing along each ray that compliments their role in behavior.

AimsOur primary aim was to establish the proportion of female orthopaedic consultants who perform arthroplasty via cases submitted to the National Joint Registry (NJR), which covers England, Wales, Northern Ireland, the Isle of Man, and Guernsey. Secondary aims included comparing time since specialist registration, private practice participation, and number of hospitals worked in between male and female surgeons.MethodsPublicly available data from the NJR was extracted on the types of arthroplasty performed by each surgeon, and the number of procedures of each type undertaken. Each surgeon was cross-referenced with the General Medical Council (GMC) website, using GMC number to extract surgeon demographic data. These included sex, region of practice, and dates of full and specialist registration.ResultsOf 2,895 surgeons contributing to the NJR in 2023, 102 (4%) were female. The highest proportions of female surgeons were among those who performed elbow (n = 25; 5%), shoulder (n = 24; 4%), and ankle (n = 8; 4%) arthroplasty. Hip (n = 66; 3%) and knee arthroplasty (n = 39; 2%) had the lowest female representation. Female surgeons had been practising for a median of 10.4 years since specialist registration compared to 13.7 years for males (p < 0.001). Northern Ireland was the region with the highest proportion of female arthroplasty surgeons (8%). A greater proportion of male surgeons worked in private practice (63% vs 24%; p < 0.001) and in multiple hospitals (74% vs 40%; p < 0.001).ConclusionOnly 4% of surgeons currently contributing cases to the NJR are female, with the highest proportion performing elbow arthroplasty (5%). Female orthopaedic surgeons in the NJR are earlier in their careers than male surgeons, and are less involved in private practice. There is a wide geographical variation in the proportion of female arthroplasty surgeons.Cite this article: Bone Jt Open 2024;5(8):637–643.

The X-ray reflectance of Pt-based coatings deposited by atomic layer deposition (ALD) has been measured in support of assessing the feasibility of using this deposition method for the production of X-ray mirror coatings that can achieve high X-ray reflectance without causing unacceptably large degradation of mirror figure as a result of coating stress-driven substrate deformation. Specifically, reflectance measurements of single-layer Pt, Al2O3/Pt bilayer, and Al2O3/Ni/Pt trilayer coatings grown by ALD on flat Si substrates were made using synchrotron radiation at X-ray energies in the range from 0.35 to 10 keV, revealing that the reflectance of the bilayers and trilayers is superior to that of single-layer sputtered Ir below 3.5 keV. Single-layer Pt and Al2O3/Pt bilayer coatings produced using thermal ALD were also deposited onto both the front and back surfaces of thin, figured, sub-arcsecond-quality X-ray telescope mirror segments made of polished, single-crystal Si, without discernible degradation of surface figure. These results, along with the successful implementation of batch-coating of two such mirrors simultaneously with high-reflectance coatings grown by thermal ALD, demonstrate the viability of employing stress-balanced, double-sided ALD coatings to mitigate substrate deformation resulting from film stress in high-reflectance coatings. This approach may thus enable the mass production of high-performance, sub-arcsecond X-ray telescope mirrors.
“Come into This Space and Take”
Authors: Farquhar Zoe C. 
Published: August 2024

Abstract
This essay navigates the complexities of visibility politics for Black counterpublics and enclave spaces. Specifically, this essay explores how the Netflix documentary starring Chelsea Handler, Hello, Privilege. It's Me, Chelsea (2019) illustrates how rhetorics of whiteness are deployed to enter Black spaces, exploit Black intellectual labor, and facilitate anti-blackness while purporting to do important anti-racist work. In a culture where anti-racism has become increasingly popular and profitable, Hello, Privilege exemplifies how the anti-racist industry commodifies Black culture, experiences, and struggles while bolstering white privilege.

This research aims to provide empirical evidence that is related to the effect of financial distress and profitability on earnings management. Earnings management is measured by the Jones Modified Model. Financial distress is measured by the Grover Model. Profitability is proxied by profit margin, return on assets, return on equity, and earnings per share. The research sample of this study is a consumer goods industry which is listed in Indonesia Stock Exchange 2015-2017. Purposive sampling was used as a sampling method and obtained 108 samples. The analysis technique used is panel regression analysis with Stata 14. The results of this study indicate that each of financial distress, return on equity, and earnings per share has an effect on earnings management while profit margin and return on assets do not affect earnings management.
Wychowanie do człowieczeństwa Eduarda Sprangera
Authors: Zieliński Paweł 
Published: August 2024

The author reconstructs and interprets the Education to Humanity by Eduard Spranger, a prominent German philosopher, psychologist, and pedagogue, whose pedagogical work is little known in Poland. The barbarism of the Russian-Ukrainian War is a reminder of how topical the issue of realising the value of humanity is in contemporary education. Spranger not only answers the question of what humanity is, but points to specific, rather than general, methods of its formation in young people. He refers to selected teaching methods of Socrates, specifically to moral stories, and also to meditation, as in Zen Buddhism. He links a number of universal values to the formation of humanity, such as self-reflection, dignity of the person, self-criticism, responsibility, conscience, and love. Spranger’s theory of upbringing is holistic. Its teleology is oriented towards personality development, with an emphasis on altruistic values and human moral development. It is largely consistent with the pedagogical thought of Otto F. Bollnow, Abraham H. Maslow, Theodor Adorno, Hans Waldenfens, Andrzej Szyszko-Bohusz, Hilarion G. Petzold and other contemporary scholars – humanists. It also seems a continuation of Immanuel Kant’s, Johann H. Pestalozzi’s, Leo N. Tolstoy’s, Rudolf Steiner’s and even Mencius’s concepts of education, as well as those of Zen and Daoist teachers. Spranger opposed the idea of a transhumanism based on modern technology, as well as the instrumental and utilitarian treatment of nature, and the materialistic and technological trend, that is omnipresent in modern human life.
Trajectory Similarity Measurement: An Efficiency Perspective
Authors: Chang Yanchuan , Tanin Egemen , Cong Gao , Jensen Christian S. , Qi Jianzhong 
Published: August 2024

Trajectories that capture object movement have numerous applications, in which similarity computation between trajectories often plays a key role. Traditionally, trajectory similarity is quantified by means of non-learned measures, e.g., Hausdorff, that operate directly on the trajectories. Recent studies exploit deep learning to map trajectories tod-dimensional vectors, called embeddings. Then, some distance measure, e.g., Manhattan, is applied to the embeddings to quantify trajectory similarity. The resulting similarities are inaccurate: they only approximate the similarities obtained using the non-learned measures. As embedding distance computation is efficient, focus has been on obtaining embeddings of high accuracy.Adopting an efficiency perspective, we analyze the time complexities of both the non-learned and the learning-based approaches, finding that the time complexities of the former approaches are not necessarily higher. Through extensive experiments on open datasets, we find that only a few learning-based approaches can deliver the promised higher efficiency, when the embeddings can be pre-computed, while non-learned approaches are more efficient for one-off computations. Among the learning-based approaches, the self-attention-based ones are the fastest and the most accurate. These results have implications for the use of trajectory similarity approaches given different application requirements.
Mobile borders and chronotope of homeland
Authors: Smagulova Juldyz , Imyarova Zulfiya 
Published: August 2024

AbstractIn this article, we examine the imagining of homeland as one of the discursive practices of rearticulating belonging within new state borders. The study focuses on an under-researched diasporic group of the Dungan community in Kazakhstan and examines how the diaspora subjects make sense of shifting borders and legitimize their presence within an increasingly homogenizing nation-state. Specifically, our interrogation focuses on spatiotemporal frames for re-imagining the notion of homeland and belonging in the context of shifting borders and changing conditions of settlement. We show how the Dungan negotiate their social positioning by re-orienting themselves to their ancestral home and their current place by discursively constructing double loss – permanent dispersal from China, their ancestral homeland, and displacement from the home and ideal life they managed to build in the Soviet Union. This spatiotemporal perspective allows us to see that the notion of homeland, a defining feature of diaspora and often viewed as naturalized and fixed, is a fluid construct, and one which can be rooted in time just as much as in space. The study contributes to understanding of processes of diasporic imagination in response to sociopolitical changes, and shows us that feelings of displacement can arise without physical dispersal, that temporality is as important in the processes of constructing diasporas as spatial movement.
Using language in boundary-making: nation-state building in the early years of the Turkish Republic (1927–1965)
Authors: Ahn Elise S. 
Published: August 2024

AbstractIn 1927, the nascent Turkish Republic engaged in its first endeavor as a nation-state to systematically account for all its citizens. Included on this census were a number of different attributes the Turkish government wanted to know about its citizenry, including language. In the Turkish context, examining the language categories on the census between 1927 and 1965 and how – they changed over time – provides insight into how the new republic was imagining its citizenry (and by extension, itself). The dynamic nature of the language categories not only reflected an ambiguity that the nascent nation-state had regarding what constituted salient ethnolinguistic category for governing purposes, it also reflected the realization and subsequent politicization of minoritized populations over time. After examining the history of the development of the Turkish census, the article outlines the use of running records like censuses to provide insight into how state apparatuses were creating taxonomies to realize (or visualize) its citizenry and the value of utilizing such unobtrusive measures in Durkheimian social facts such as those who are “Us” and those who are “Other”. This article then situates the census data in its geographical context and demonstrates how the delineation of historic parts of the country that were settled by non-Turkish communities were ones that were then later demarcated into smaller administrative borders, allowing for closer government and military oversight. While this article is an exploratory case study of the Turkish census as part of its state building process, I contend that looking at how language categories were used in the 1927–1965 censuses provides insight into the nature of the Turkish government’s imaginings regarding its citizenry. In particular, the use of language data as a proxy for ethnicity was concomitant with processes of internal border demarcation that was taking place to increase government oversight in particular non-Turkish contexts, resulting in a “new” form of minoritization and marginalization in the Turkish Republic.
Design and simulation analysis of an extrusion structure based on screw extrusion 3D printing

Published: August 2024

Abstract
In response to the problems of 3D printing, such as uneven wire discharge and easy clogging of printing nozzles in FDM (Fused Deposition Modeling) printing technology, this paper develops a screw extrusion 3D printing melting deposition system based on simulation. The simulation results show that the maximum deformation of the screw occurs at the tail end, with a maximum value of 0.04 mm, while the fluid pressure and the pressure on the surface of the screw gradually increase along the direction of extrusion, and the maximum pressure occurs near the nozzle, with a value of 0.13 MPa. The fluid pressure is positively correlated with the screw speed and negatively correlated with the screw pitch. The fitting formula is obtained by numerical simulation of the screw speed and the flow velocity at the nozzle outlet. Using a self-made screw extrusion 3D printing equipment, relevant experiments are conducted to explore the influence of different layer thicknesses and line spacings on the mechanical properties of printed samples, as well as the influence of printing speed on surface quality. It is found that layer thickness has a significant impact on the bending strength of printed samples, with a maximum value of 24.74 MPa and a minimum of 19.21 MPa. The bending strength decreases by 28.79 % from 0.6 mm to 1.0 mm layer thickness. The line spacing has a significant impact on the tensile strength of printed samples, with a maximum value of 27.22 MPa and a minimum of 21.16 MPa. As the printing speed increases, the surface roughness of the printed piece also gradually increases from Ra = 389.28 μm at v = 30 mm/s to Ra = 535.45 μm at v = 70 mm/s, an increase of 37.55 %.
The (in)justice of EMI: a critical discourse analysis of two key stakeholders’ views on the Polytechnic University of Milan court case
Authors: Zuaro Beatrice , Yuksel Dogan , Wingrove Peter , Nao Marion , Hultgren Anna K. 
Published: August 2024

AbstractWhile English-medium Instruction (EMI) continues to be appealing for various stakeholders, it also raises some epistemological and ethical concerns, which have in the past found expression in polarized debates. A well-known example is the 2012 Milan court case, in which the academic staff sued the Polytechnic University of Milan over its attempt to promote an EMI-only policy. Now almost ten years after the case, the motivations of the key proponents and opponents of the policy are yet to be explored in depth. In order to explain how different interpretations of EMI could result in such unreconcilable positions, in this paper we adopt a new analytical angle, focusing on twoelite participants: the rector who promoted the policy and the lawyer (also a faculty member) who represented the lecturers in court. Via a critical discourse analysis of interviews to these participants, we aim to unveil how different stakeholders from the same context frame EMI in relation to ideas of justice/injustice. Results indicate that, despite comparable personal commitment to education and similar understandings of language/power interactions, the participants evaluate English against different frames of reference (i.e. a horizon of globalized education, versus the traditional national understanding of the goals of education). This leads to diametrically opposite evaluations of the growing presence of English in higher education.
