[{"abstract":[{"lang":"eng","text":"This article examines the use of the Arabic term khalīfah in the Qur’an through the lens of its implicit historical-political theology. To achieve this, the study employs a comparative analysis of the concept of vicarious kingship within the Syriac tradition. The findings suggest that the Qur’an rejects the notion of a historical replacement or substitution of believing individuals or groups with new ones. Furthermore, it challenges the framework of a political theology that envisions the typological and eschatological fulfillment of messianic rulership. Instead, the term khalīfah primarily emphasizes the inherently political nature of humanity, in which each individual is continuously accountable to their Creator."}],"related_material":{"link":[{"relation":"table_of_contents","url":"https://www.degruyterbrill.com/de/document/doi/10.1515/jiqsa-2024-0016/html"}]},"publication":"Journal of the International Qur’anic Studies Association","type":"journal_article","department":[{"_id":"469"}],"date_created":"2026-06-25T19:36:18Z","date_updated":"2026-06-25T19:36:31Z","article_type":"original","intvolume":"        11","title":"History and political Theology: The term khalīfah in the Qur’an","year":"2026","author":[{"id":"83446","first_name":"Zishan","last_name":"Ghaffar","full_name":"Ghaffar, Zishan"}],"doi":"https://doi.org/10.1515/jiqsa-2024-0016","language":[{"iso":"eng"}],"citation":{"apa":"Ghaffar, Z.

Here, we systematically quantify the irradiance-dependent behavior of ordered mesoporous In2O3 under visible light illumination. Photoconductivity measurements reveal two distinct irradiance regimes consistent with trap-limited transport at low power and recombination- or saturation-limited transport at high power. Gas sensing experiments towards CO and H2 show a pronounced non-monotonic response, reaching maximum responses of 0.74 for 135 ppm CO at 67 mW cm−2 and 0.64 for 90 ppm H2 at 11 mW cm−2, followed by strong suppression at higher irradiance. Illumination also accelerated the response kinetics. At 60 ppm, t90 decreases from 96 to 12 s for CO and 141 to 27 s for H2, corresponding to an 8- and 5-fold faster response time, respectively. Near-ambient pressure-XPS under controlled atmosphere and density functional theory calculations indicate defect-mediated excitation. Oxygen vacancy states and illumination-induced modification of surface oxygen species govern this behavior. The results establish irradiance as a critical mechanistic parameter that determines whether In2O3 operates in a surface-controlled or bulk photoconductive regime. These findings highlight the need to explicitly optimize and report irradiance in illuminated gas sensor studies, and not only the power consumption of the light source."}],"publication":"ACS Sensors","doi":"10.1021/acssensors.6c01100","article_number":"acssensors.6c01100","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2026-06-24T11:35:36Z","article_type":"original","year":"2026","title":"Role of Irradiance in Light-Activated In<sub>2</sub>O<sub>3</sub>Gas Sensors: Why More Light Is Not Always Better","publication_identifier":{"issn":["2379-3694","2379-3694"]},"author":[{"last_name":"Voth","first_name":"Sven","full_name":"Voth, Sven"},{"last_name":"Zhao","first_name":"Zhenyu","full_name":"Zhao, Zhenyu"},{"full_name":"Baier, Dominik","last_name":"Baier","first_name":"Dominik"},{"last_name":"Glass","first_name":"Alexandra","full_name":"Glass, Alexandra"},{"id":"60250","last_name":"Elgabarty","orcid":"0000-0002-4945-1481","first_name":"Hossam","full_name":"Elgabarty, Hossam"},{"full_name":"Sandberg, Oskar J.","last_name":"Sandberg","first_name":"Oskar J."},{"full_name":"Grundmeier, Guido","first_name":"Guido","last_name":"Grundmeier","id":"194"},{"id":"23547","orcid":"0000-0003-1711-2722","first_name":"Michael","last_name":"Tiemann","full_name":"Tiemann, Michael"},{"first_name":"Jan-Henrik","last_name":"Smått","full_name":"Smått, Jan-Henrik"},{"last_name":"Anttu","first_name":"Nicklas","full_name":"Anttu, Nicklas"},{"full_name":"de los Arcos, Teresa","last_name":"de los Arcos","first_name":"Teresa"},{"id":"11848","full_name":"Weinberger, Christian","last_name":"Weinberger","first_name":"Christian"}]},{"status":"public","_id":"66040","publisher":"AIP Publishing","volume":139,"user_id":"54556","citation":{"short":"C.

Lower growth rates and a reduced N content, favoring graphitic sp2 structures, hinder industrial scalability due to prolonged deposition times and produce softer, less dense films with inferior hardness, elasticity, and wear resistance. Carbon nitride films deposited by magnetron sputtering exhibit growth behavior strongly influenced by plasma–surface interactions. However, nitrogen resputtering and reduced film growth rates are commonly attributed to chemical etching by positive ions. We propose an additional, unreported power-dependent mechanism involving negative ions formed at the carbon target. These ions are accelerated through the plasma sheath, reaching the substrate with high kinetic energy and inducing both chemical and physical resputtering. This effect is localized to the geometrical projection of the target, as shown by spatially resolved analysis: ellipsometry reveals thickness reduction, and x-ray photoelectron spectroscopy and Raman spectroscopy indicate nitrogen depletion within this region. Correlation between stoichiometry and structural signatures confirms the decisive role of negative ions in modifying the film composition and microstructure. At the same time, the composition of the gas mixture exerts only a minor effect.</jats:p>"}],"date_created":"2026-06-25T12:15:04Z","department":[{"_id":"302"}],"type":"journal_article"},{"author":[{"last_name":"Voth","first_name":"Sven","full_name":"Voth, Sven"},{"first_name":"Zhenyu","last_name":"Zhao","full_name":"Zhao, Zhenyu"},{"last_name":"Baier","first_name":"Dominik","full_name":"Baier, Dominik"},{"first_name":"Alexandra","last_name":"Glass","full_name":"Glass, Alexandra"},{"first_name":"Hossam","last_name":"Elgabarty","full_name":"Elgabarty, Hossam"},{"last_name":"Sandberg","first_name":"Oskar J.","full_name":"Sandberg, Oskar J."},{"first_name":"Guido","last_name":"Grundmeier","full_name":"Grundmeier, Guido"},{"last_name":"Tiemann","first_name":"Michael","full_name":"Tiemann, Michael"},{"first_name":"Jan-Henrik","last_name":"Smått","full_name":"Smått, Jan-Henrik"},{"last_name":"Anttu","first_name":"Nicklas","full_name":"Anttu, Nicklas"},{"full_name":"de los Arcos de Pedro, Maria Teresa","orcid":"0000-0002-8684-273X ","last_name":"de los Arcos de Pedro","first_name":"Maria Teresa","id":"54556"},{"last_name":"Weinberger","first_name":"Christian","full_name":"Weinberger, Christian"}],"publication_identifier":{"issn":["2379-3694","2379-3694"]},"status":"public","title":"Role of Irradiance in Light-Activated In                    <sub>2</sub>                    O                    <sub>3</sub>                    Gas Sensors: Why More Light Is Not Always Better","year":"2026","publication_status":"published","date_updated":"2026-06-25T12:18:13Z","publisher":"American Chemical Society (ACS)","_id":"66041","language":[{"iso":"eng"}],"article_number":"acssensors.6c01100","user_id":"54556","doi":"10.1021/acssensors.6c01100","citation":{"bibtex":"@article{Voth_Zhao_Baier_Glass_Elgabarty_Sandberg_Grundmeier_Tiemann_Smått_Anttu_et al._2026, title={Role of Irradiance in Light-Activated In                    <sub>2</sub>                    O                    <sub>3</sub>                    Gas Sensors: Why More Light Is Not Always Better}, DOI={<a href=\"https://doi.org/10.1021/acssensors.6c01100\">10.1021/acssensors.6c01100</a>}, number={acssensors.6c01100}, journal={ACS Sensors}, publisher={American Chemical Society (ACS)}, author={Voth, Sven and Zhao, Zhenyu and Baier, Dominik and Glass, Alexandra and Elgabarty, Hossam and Sandberg, Oskar J. and Grundmeier, Guido and Tiemann, Michael and Smått, Jan-Henrik and Anttu, Nicklas and et al.}, year={2026} }","ama":"Voth S, Zhao Z, Baier D, et al.

The growing number of joining tasks requires a large number of joining elements. Friction spun joint connectors (FSJC) offer an innovative approach that meets the growing demand for flexibility. This process combines rotational movement and axial force to create targeted friction heating, enabling the production of FSJCs and the joining of various sheet metal materials. The shape of the FSJC can be optimally adapted to the joining situation in question, providing a significant advantage in terms of process chain versatility. This paper investigates FSJCs made of the steel grades C45E+C (1.1191) and 115CrV3 (1.2210), the effect of in situ quenching during the joining process. The influences of the essential parameters of rotational speed, feed rate, and FSJC length on the mechanical properties after quenching are being focused on and compared to similar conditions during joining without quenching. At the same time, the material change is analyzed to determine the effect of different alloy approaches on hardness profiles and strength characteristics in cross-tensile testing. For this purpose, systematic test series with varying process parameters are conducted and evaluated using hardness measurements and cross-tensile tests.</jats:p>","lang":"eng"}],"publication":"Transactions of the Indian Institute of Metals","issue":"6","department":[{"_id":"156"}],"type":"journal_article","date_created":"2026-06-29T06:35:48Z"},{"publisher":"Springer Science and Business Media LLC","_id":"66074","language":[{"iso":"eng"}],"main_file_link":[{"url":"https://link.springer.com/article/10.1007/s11858-026-01806-3","open_access":"1"}],"user_id":"37888","doi":"10.1007/s11858-026-01806-3","author":[{"orcid":"https://orcid.org/0000-0003-0318-0329","first_name":"Franz Yannik","last_name":"Fleischer","full_name":"Fleischer, Franz Yannik","id":"42660"},{"full_name":"Biehler, Rolf","last_name":"Biehler","first_name":"Rolf","id":"16274"}],"publication_identifier":{"issn":["1863-9690","1863-9704"]},"status":"public","year":"2026","title":"Informal approaches to predictive modeling: fostering data literacy and critical engagement through decision tree construction","publication_status":"published","date_updated":"2026-06-29T07:47:44Z","date_created":"2026-06-29T07:43:33Z","department":[{"_id":"363"}],"oa":"1","type":"journal_article","citation":{"ieee":"F.

Focusing on the most important private firms operating in U.S. industries, we investigate whether private peer disclosure—despite differing substantially from public firm disclosure—is incorporated into analysts’ forecasts. In a cross-sectional analysis, we document lower forecast quality in industries where private peers’ disclosure intensity is low. In contrast, when private peers’ disclosure intensity is high, forecast quality does not differ from that in industries with only public peers. We find consistent results for a subsample of U.S. private peers. Consistent with this interpretation, a difference-in-differences analysis documents increased analyst forecast activity around the disclosure dates of private peers. Together, these findings indicate that analysts incorporate private peers’ information when these peers are both economically important and sufficiently transparent, and highlight that variation in private firms’ disclosure intensity generates heterogenous externalities for public firms. Overall, our evidence supports a cost-benefit trade-off in analysts’ information acquisition, and, by documenting the relevance of private peers’ information for public firms, contributes to the debate on the externalities of private firms’ disclosure transparency.","lang":"eng"}],"citation":{"mla":"Beyer, Bianca, et al. <i>Private Peers’ Disclosure Transparency and Public Firms’ Information Environment</i>.

In most of its experiments, ICO has been investigated in a photonic platform. Here, we investigate ICO in a cavity quantum electrodynamics system composed of two cavities. Our results show that ICO can create highly entangled states of two distant cavity fields that never interact directly independent of the initial (excited or ground) state of the atom. These entangled states can have the form of one- or two-photon NOON states. We show that ICO can interchange one photon between both cavities without changing the state of the atom, something that is impossible to achieve for two cavities in well-defined order. Furthermore, the vacuum Rabi oscillations either disappear or lose their sinusoidal form with ICO. Our results show the potential that ICO can offer in the paradigm of light-matter interaction for coherently controlling atom-field observables.</jats:p>","lang":"eng"}],"language":[{"iso":"eng"}],"article_number":"023295","doi":"10.1103/wgr6-1g5m","publication_identifier":{"issn":["2643-1564"]},"author":[{"full_name":"Castaños-Cervantes, Luis Octavio","last_name":"Castaños-Cervantes","first_name":"Luis Octavio"},{"full_name":"Procopio, Lorenzo M.","last_name":"Procopio","first_name":"Lorenzo M."},{"full_name":"Bartley, Tim J.","first_name":"Tim J.","last_name":"Bartley"}],"year":"2026","title":"Indefinite causal order in cavity quantum electrodynamics","intvolume":"         8","article_type":"original","date_updated":"2026-06-29T08:11:13Z","publication_status":"published"},{"date_updated":"2026-06-29T10:32:34Z","author":[{"id":"21863","full_name":"Fuchs, Christian","orcid":"0000-0003-0589-4579","last_name":"Fuchs","first_name":"Christian"},{"first_name":"Kevin","last_name":"Friesch","full_name":"Friesch, Kevin"},{"first_name":"Joel","last_name":"Museba","full_name":"Museba, Joel"}],"status":"public","year":"2026","title":"INNOVADE Interdisciplinary Knowledge Base on Digital Democracy - D2.1 ","doi":"10.5281/zenodo.20341002","user_id":"21863","language":[{"iso":"eng"}],"_id":"61278","publisher":"INNOVADE","page":"320","main_file_link":[{"url":"https://doi.org/10.5281/zenodo.20341002","open_access":"1"}],"project":[{"_id":"1397","name":"INNOVAtive DEmocracy Through Digitalisation"}],"abstract":[{"lang":"eng","text":"This report outlines foundations of digital democracy and digital democracy research.
