AbstractDNA strand displacement reactions are vital for constructing intricate nucleic acid circuits, owing to their programmability and predictability. However, the scarcity of effective methods for eliminating circuit leakages has hampered the construction of circuits with increased complexity. Herein, a versatile strategy is developed that relies on a spatially controlled proximity split tweezer (PST) switch to transduce the biomolecular signals into the independent oligonucleotides. Leveraging the double‐stranded rigidity of the tweezer works synergistically with the hindering effect of the hairpin lock, effectively minimizing circuit leakage compared with sequence‐level methods. In addition, the freely designed output strand is independent of the target binding sequence, allowing the PST switch conformation to be modulated by nucleic acids, small molecules, and proteins, exhibiting remarkable adaptability to a wide range of targets. Using this platform, established logical operations between different types of targets for multifunctional transduction are successfully established. Most importantly, the platform can be directly coupled with DNA catalytic circuits to further enhance transduction performance. The uniqueness of this platform lies in its design straightforwardness, flexibility, scalable intricacy, and system compatibility. These attributes pave a broad path toward nucleic acid‐based development of sophisticated transduction networks, making them widely applied in basic science research and biomedical applications.

AbstractMetallic substrates, widely studied in the context of monolithic catalysts, offer inherent advantages in heterogeneous catalysis due to their exceptional thermal conductivity and mechanical properties. However, synthesizing stable monolithic catalysts with metallic substrates in a well‐controlled manner remains a significant challenge. Here, this work introduces a simple, cost‐efficient method to fabricate robust Cu mesh‐supported thermo‐catalysts using a modified cycling chronopotentiometry approach, where the Cu mesh serves as a donor of Cu ions. In this method, the Cu mesh surface generates two distinct layers of CuO and Cu2O. In this context, CuO acts as the active phase, accounting for the high CO oxidation activity of Cu mesh catalysts with T90 ≈ 120 °C. Additionally, these catalysts exhibit considerable potential in electrocatalysis, showcasing significant research and application value.

AbstractSulfonic acid‐containing bioorganic monomers with wide molecular designability and abundant hydrogen bonding sites hold great potential to design diverse functional biocrystals but have so far not been explored for piezoelectric energy harvesting applications due to the lack of strategies to break the centrosymmetry of their assemblies. Here, a significant molecular packing transformation from centrosymmetric into non‐centrosymmetric conformation by the addition of an amide terminus in the sulfonic acid‐containing bioorganic molecule is demonstrated, allowing a high electromechanical response. The amide‐functionalized molecule self‐assembles into a polar supramolecular parallel β‐sheet‐like structure with a high longitudinal piezoelectric coefficient d11 = 15.9 pm V−1 that produces the maximal open‐circuit voltage of >1 V and the maximal power of 18 nW in nanogenerator devices pioneered. By contrast, molecules containing an amino or a cyclohexyl terminus assemble into highly symmetric 3D hydrogen bonding diamondoid‐like networks or 2D double layer structures that show tunable morphologies, thermostability, and mechanical properties but non‐piezoelectricity. This work not only presents a facile approach to achieving symmetry transformation of bioorganic assemblies but also demonstrates the terminal group and the property correlation for tailor‐made design of high‐performance piezoelectric biomaterials.

Published: December 2023

AbstractGa2O3‐based Ultraviolet‐C photodetector (UVCPD) is considered the most promising UVCPD at present and is divided into Metal‐Semiconductor‐Metal (MSM) and PN junction types. Compared with MSM‐PDs, PN‐PDs exhibit superior transient performance due to the built‐in electric field. However, current Ga2O3‐based PN‐PDs lack consideration for carrier collection and electric field distribution. In this study, PN‐PDs with an interdigital n‐Ga2O3 layer and finger electrodes are fabricated on p‐GaN/n‐Ga2O3 epilayers. Ultrafast response times of 31 µs (1/e decay) and 2.76 µs (fast component) are realized, which outperforms all Ga2O3 UVC‐PDs up to now. Under 0 V self‐powered, the responsivity (0.25 A W−1) of interdigital PD is enhanced by the interdigital electrode structure due to increasing carriers’ collection length. Under bias, the performances of interdigital PD with 41.7 A W−1 responsivity and 8243 selection ratios are significantly elevated by enhancing the built‐in electric field in the Ga2O3 region, which is 34.76 and 39.4 times those of traditional PDs, respectively. The intrinsic enhancing mechanism of interdigital structure is also investigated by interdigital PDs with various electrode spacings and perimeters. In summary, this paper not only reports a highly performed interdigitated structure p‐GaN/n‐Ga2O3 UVCPDs, but also provides guidelines for structure design in Ga2O3‐based PN‐PDs.

AbstractBackgroundGastric cancer is the most common malignant tumour of the digestive system, yet there is a lack of reported prognostic biomarkers for STAD patients.MethodsTranscriptomic expression data of STAD from GEO database, single cell sequencing data from OMIX gastric cancer database. Conservative molecular typing of gastric cancer was constructed using non‐negative matrix factorization (NMF). The abundance of 28 immune cells in the tumour samples was assessed using ssGSEA. The R package “oncoPredict” was used to predict chemotherapy response. TIDE website for immunotherapy response prediction. Finally, single cell analysis was performed to clarify the specific type annotation of STAD cells and to analysis their spatial expression.ResultsHypoxia‐score demonstrated excellent prognostic discrimination in TCGA gastric cancer samples. Among multiple deconvolution‐based algorithms for immune infiltration, Hypoxia‐score presented a general immunosuppressive efficacy across multiple datasets, as evidenced by a broad negative correlation with immune cell infiltration. By the likelihood that each group may have specific drug sensitivity to multiple chemotherapeutic and targeted agents. Results showed that high‐risk scoring patients were more sensitive to Staurosporine, Sabutoclax, and AZD8055, while low‐risk patients were more sensitive to Bortezomib, Dactinomycin, Docetaxel, Daporinad, Sepantronium, and bromide. In the immunotherapy cohort, the Hypoxia‐score presented the ability to discriminate for immunotherapy efficacy. The distribution of Hypoxia‐score in single‐cell descending space was calculated using AddModuleScore and was found to be distributed across the various cell types annotated in the single‐cell analysis. It is suggested that various cells in the tumour microenvironment are involved in hypoxia gene set processes to varying degrees.ConclusionThe Hypoxia‐score proves to be a valuable tool for assessing the prognosis of gastric cancer patients and guiding drug treatments, providing significant guidance for clinical diagnosis and treatment in the context of gastric cancer.
Cultural Change in Post-Migrant Societies: Re-imagining Communities Through Arts and Cultural Activities
Authors: Sievers Wiebke 
Published: December 2023

AbstractWhere do we stand between the exclusion of migrants as others from national narratives and traditions invented in the nineteenth century and the emergence of new narratives that include them and enable their social, political and cultural participation? This is what we discuss under the label cultural change in this volume, Cultural change in post-migrant societies: Re-imagining communities through arts and cultural activities. Since history has shown that arts and cultural activities have the potential to effectuate cultural change, we focus on the question of whether and how far they contribute to such a change in post-migrant societies. In the introduction, I explain the theme and objective of the present volume. Subsequently, I place it in the wider debate on social and cultural change in migration and cultural studies. I then explain in more detail where and how this volume moves beyond the state-of-the-art. Finally, I discuss our results in the light of recent changes in migration studies.
Refugees in a Multimedia Dialogue: A Methodology that Inspires the Creation of New Narratives on Migration in an Evolving Process of Change
Authors: Kamm Martina , Meyer Lhamo 
Published: December 2023

AbstractBased on the project No child’s play this chapter describes how arts-based methods and, especially, (visual) storytelling can inspire the creation of new narratives on migration in a slow process of change. No child’s play is a long-term project of more than 13 years that deals with the consequences of persecution, war and flight for refugees and their families as well as the Swiss public. The project is a good example of participatory action research (PAR), as it contributes to the empowerment of and awareness among the different groups in society which participated in the project. The analysis shows that arts-based methods create an emotional access and awareness, serving as a ‘teaser’. They can move, especially young participants, to reflect and talk about personal experiences or attitudes related to origins, war, trauma, home or discrimination. Many would speak about their past in front of others for the very first time, suddenly realising that their stories matter and that it is important to deal with them. This chapter illustrates this process of change with various examples. Moreover, it analyses two prominent perspectives that shaped the narratives. One is the family and its ambivalent role as a place of refuge and (over)protection. The other is the role of religion and faith as coping strategies and cultural ties for refugee families.
Culture as Deconstruction and Participation? Reflections from a field…in Transition
Authors: Moralli Melissa , Musarò Pierluigi 
Published: December 2023

AbstractThis chapter explores how different artistic activities can promote cultural and social change in terms of both 1) narratives built around migration and diversity and 2) practices of resistance and social inclusion facilitating intercultural dialogue. Our reflection focuses on a double level of analysis. From the methodological point of view, it investigates how, in the project “Atlas of Transitions”, the approach of action research sustains the conditions under which groups of people can organise and learn from their own experience, showing a major shift in both the reflection on knowledge production within and outside the academy and in the relations between research, action and social change. Secondly, our analysis focuses on the processes of audience development which encourage the audience of artistic practices to intervene directly in the performances. In this way, both action research and audience development can intervene in supporting a critical reflection by the participants, nurturing change and awareness about migration and linking the artistic, civic and political spheres.
Youth in the City: Fostering Transcultural Leadership for Social Change
Authors: Dutto Matteo , Ricatti Francesco , Simeone Luca , Wilson Rita 
Published: December 2023

AbstractWhen considering the impact of migrants’ creative practices within superdiverse urban environments and their ability to both represent and engender linguistic, cultural and social change, there is a tendency to rigidly demarcate and separate the crucial roles played by artists, researchers, educators, students and activists. Furthermore, little consideration is usually given to the development of transcultural and multilingual youth’s ability to lead and engender such changes. The focus tends to be on the impact of the final artistic product, rather than on the impact of the complex participatory processes through which many of these artistic products have been developed. Drawing from the transdisciplinary work we conducted for ourYouth in the Cityinitiative (YITC), this chapter challenges these prevailing assumptions. Using theLa Nostra Pratoproject (2019–2020) as an illustrative example, we suggest an alternative model for understanding and engendering social and cultural change: one that focuses on the transdisciplinary and transcultural processes through which young people in superdiverse urban contexts develop leadership skills through creative practices.In loving memory of Salvatore Iaconesi, who taught us the meaning and power of facing the world with a sense of “meraviglia”.
How to Tell the History of Cultural Change Through Migration: A Post-migrant Field Theoretical Approach
Authors: Sievers Wiebke 
Published: December 2023

AbstractHow can we tell the history of cultural change through migration? This chapter presents a new theoretical and methodological approach, which I developed in response to this question by combining Bourdieu’s field theory with a post-migrant perspective. While my focus is on literary fields, the approach may also serve as an inspiration for exploring similar changes in other fields, including not only the arts but also politics and the economy. Bourdieu’s literary field theory allows us to understand authors and their works as part of a societal process of change. In that respect, it is ideal to grasp how literary fields have changed in response to immigration. Yet, due to his methodological nationalism, Bourdieu ignores nationalisation as a process that implied the drawing of boundaries towards immigrants and their descendants in literary fields on four levels: language, literary traditions, literary themes and the right to state support. These mechanisms of exclusion have become naturalised in nationalised literary fields to such an extent that they were long also accepted by immigrants and their descendants. Only when they began to fight exclusion in and through their literary works did immigrants and their descendants become accepted as authors in literary fields.
Continuity or Change? How Migrants’ Musical Activities (Do not) Affect Ethnic Boundaries
Authors: Parzer Michael , Mijić Ana 
Published: December 2023

AbstractOur article discusses whether and how the musical activities of migrants and their descendants contribute to cultural change. Drawing on Andreas Wimmer’s work, we examine both the benefits and limitations of his ‘boundary-making approach.’ In so doing, we define cultural change as a transformation of ethnic boundaries. Based on the assumption that these boundaries arise from social classification, we shed light on the various processes that shape how musicians and their music are located in the symbolic order of internal identification and external categorisation. Following Wimmer, we suggest distinguishing between three fundamental modes of how social activities in the field of music affect boundaries: (1) Boundary changing, which includes boundary blurring and reinforcing; (2) boundary shifting, meaning the contraction and expansion of an ethnic boundary; and (3) boundary crossing, which occurs when an individual shifts sides and crosses a given boundary by changing their position. By adapting Wimmer’s typology, we aspire to provide a toolkit for analysing ethnic boundaries in the musical field and to contribute to the debate on the challenges of researching migrants’ impact on the social and cultural transformation of contemporary societies.
How Does “Migrant” and “World” Music Change Local and National Cultures? An Insight from the Cologne Carnival, Related Antiracist Networks and Recent Cultural Politics
Authors: Salzbrunn Monika , Ellinghaus Birgit 
Published: December 2023

AbstractNina Glick Schiller and Ayse Çağlar have invited migration scholars to constructively question the transnational paradigm by “locating migration”. Based on our work on the dynamics of the Cologne carnival, this chapter assesses the impact of “migrant” and “world” music on local and national cultural policies.Cologne’s history has always been shaped by migration, even though the enrichment of the music and carnival scene, thanks to migrants, has been recognised and celebrated only for a couple of decades. Over the last 30 years, Cologne’s carnival as well as the broader music scene in Cologne has undergone profound changes: new repertories pertaining to different social and religious references, updated lyrics of songs, hybrid styles with sources from musicians with multiple origins and links between the anti-Nazi resistance movements and current anti-fascist initiatives. Diversification processes have been initiated both top-down and bottom-up, leading to resilient changes concerning the use of musical references and the visibility of new cultural actors. We analyse the creativity and openness of the cultural scene of Cologne, taking into consideration political consciousness, decision-making and the re-shaping of institutions and the short- and long-term strategies and effects of cultural politics. Starting from a local case study, we broaden our perspective to regional dynamics and put these in a broader national and supranational context.
Can Micro Practices Change National Heritage? Norwegian National Day Celebrations in a Multicultural Setting
Authors: Nikielska-Sekuła Karolina 
Published: December 2023

AbstractPresenting the engagement of immigrants, their descendants and native Norwegians with Norwegian Constitution Day celebrations, this chapter discusses how people de facto change elements of national culture through their micro practices. It explores data collected between 2013 and 2020 during the Norwegian Constitution Day celebrations in the area of Drammen municipality, Norway. The analysis is supported theoretically by the concept of the third space. Additionally, I use the concept of heritage in becoming to problematise the dynamic between a genealogical model of national heritage and its interpretation performed by people in relation to the spatial, cultural and structural circumstances in which they live. The chapter argues that the individual patterns of Norwegian Constitution Day celebrations exercised by immigrant minorities constitute a third space. Immigrants de facto change the Norwegian national heritage. Subsequently, I analyse the extent to which this change is reflected at the level of mainstream celebrations and the ways in which it is mediated by agents of non-change. Moreover, the chapter discusses the problem of identity reductionism and the reification of ethnicity present in multicultural societies, arguing that the performances of the actors within the third space may serve as means of resistance against “groupism”.
A Framework for Accessibility in XR Environments

Published: December 2023

AbstractDigital accessibility is vital for ensuring equal access and usability for individuals with disabilities. However, addressing the unique challenges faced by individuals with disabilities in XR environments remains a complex task. This paper presents an ongoing accessibility framework designed to empower developers in creating inclusive XR applications. The framework aims to provide a comprehensive solution, addressing the needs of individuals with disabilities, by incorporating various accessibility features, based on XR accessibility guidelines, best practices, and state of the art approaches. The current version of the framework has focused on the accessibility of XR environments for blind or partially sighted users, enhancing their interaction with text, images, videos, and 3D artefacts. The proposed work lays the foundation for Extended Reality (XR) developers to easily encompass accessible assets. In this respect, it offers customizable text settings, alternative visual content text, and multiple user interaction control mechanisms. Furthermore, it includes features such as edge enhancement, interactive element descriptions with dynamic widgets, scanning for navigation, and foreground positioning of active objects. The framework also supports scene adaptations upon user demand to cater to specific visual needs.
Single-soft emissions for amplitudes with two colored particles at three loops
Authors: Herzog Franz , Ma Yao , Mistlberger Bernhard , Suresh Adi 
Published: December 2023

AbstractWe compute the three-loop correction to the universal single-soft emission current for the case of scattering amplitudes with two additional color-charged partons. We present results valid for QCD and$$ \mathcal{N} $$N= 4 super-symmetric Yang-Mills theory. To achieve our results we develop a new integrand expansion technique for scattering amplitudes in the presence of soft emissions. Furthermore, we obtain contributions from single final-state parton matrix elements to the Higgs boson and Drell-Yan production cross section at next-to-next-to-next-to-next-to leading order (N4LO) in perturbative QCD in the threshold limit.
