However, small and medium-sized enterprises and public organizations face significant challenges navigating and leveraging these ecosystems due to resource constraints, knowledge gaps, and partnership difficulties. While digital innovation hubs have been introduced as potential intermediaries to foster innovation, existing models primarily focus on individual solutions and networking rather than orchestrating service innovation. This study investigates the design of a digital service innovation hub as an orchestrating entity that facilitates service innovation within ecosystems. Under the design science research paradigm, we analyze the challenges faced by small and medium-sized enterprises and public organizations and derive design requirements for these hubs.

Recent advances in artificial intelligence, including learning approaches like reinforcement\r\nlearning and architectures like transformers and foundation models, combined with access to massive datasets, has created attractive\r\nopportunities to apply those data-hungry techniques to this problem. We argue that the focus on massive amounts of pre-collected\r\ndata, and the resulting learning paradigm, where humans demonstrate and robots learn in isolation, is overshadowing a specialized\r\narea of work we term Human-Interactive-Robot-Learning (HIRL). This paradigm, wherein robots and humans interact during the\r\nlearning process, is at the intersection of multiple fields (artificial intelligence, robotics, human-computer interaction, design and others)\r\nand holds unique promise. Using HIRL, robots can achieve greater sample efficiency (as humans can provide task knowledge through\r\ninteraction), align with human preferences (as humans can guide the robot behavior towards their expectations), and explore more\r\nmeaningfully and safely (as humans can utilize domain knowledge to guide learning and prevent catastrophic failures). This can result\r\nin robotic systems that can more quickly and easily adapt to new tasks in human environments. The objective of this paper is to\r\nprovide a broad and consistent overview of HIRL research and to guide researchers toward understanding the scope of HIRL, and\r\ncurrent open or underexplored challenges related to four themes — namely, human, robot learning, interaction, and broader context.\r\nThe paper includes concrete use cases to illustrate the interaction between these challenges and inspire further research according to\r\nbroad recommendations and a call for action for the growing HIRL community"}],"status":"public"},{"doi":"10.1103/7l6y-hdw5","title":"Antiferromagnetic ordering and critical behavior induced giant magnetocaloric effect in distorted kagome lattice <mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\"><mml:mrow><mml:mi mathvariant=\"normal\">G</mml:mi><mml:msub><mml:mi mathvariant=\"normal\">d</mml:mi><mml:mn>3</mml:mn></mml:msub><mml:mi>BW</mml:mi><mml:msub><mml:mi mathvariant=\"normal\">O</mml:mi><mml:mn>9</mml:mn></mml:msub></mml:mrow></mml:math>","date_created":"2025-09-17T13:08:11Z","author":[{"full_name":"Wang, Zhuoqun","last_name":"Wang","first_name":"Zhuoqun"},{"first_name":"Xueling","last_name":"Cui","full_name":"Cui, Xueling"},{"last_name":"Treu","full_name":"Treu, Tim","first_name":"Tim"},{"full_name":"Guo, Jiesen","last_name":"Guo","first_name":"Jiesen"},{"first_name":"Xinyang","full_name":"Liu, Xinyang","last_name":"Liu"},{"first_name":"Marvin","full_name":"Klinger, Marvin","last_name":"Klinger"},{"first_name":"Christian","orcid":"0009-0006-4365-5607","last_name":"Heil","full_name":"Heil, Christian","id":"120539"},{"first_name":"Nvsen","last_name":"Ma","full_name":"Ma, Nvsen"},{"last_name":"Sheng","full_name":"Sheng, Xianlei","first_name":"Xianlei"},{"last_name":"Deng","full_name":"Deng, Zheng","first_name":"Zheng"},{"full_name":"Lu, Xingye","last_name":"Lu","first_name":"Xingye"},{"first_name":"Xiancheng","last_name":"Wang","full_name":"Wang, Xiancheng"},{"last_name":"Li","full_name":"Li, Wei","first_name":"Wei"},{"full_name":"Gegenwart, Philipp","last_name":"Gegenwart","first_name":"Philipp"},{"last_name":"Jin","full_name":"Jin, Changqing","first_name":"Changqing"},{"first_name":"Kan","last_name":"Zhao","full_name":"Zhao, Kan"}],"volume":9,"publisher":"American Physical Society (APS)","date_updated":"2025-09-17T14:21:31Z","citation":{"ama":"Wang Z, Cui X, Treu T, et al.

DWs show very different properties as compared to their hosting bulk crystal, in particular with respect to the high local electrical conductivity. The objective of this work is to demonstrate DW conductivity up to temperatures as high as 400 °C which extends previous studies significantly. Experimental investigation of the DW conductivity of charged, inclined DWs is performed using 5 mol % MgO-doped lithium niobate single crystals. Current–voltage (  ) curves are determined by DC electrometer measurements and impedance spectroscopy and found to be identical. Moreover, impedance spectroscopy enables to recognize artifacts such as damaged electrodes. Temperature dependent measurements over repeated heating cycles reveal two distinct thermal activation energies for a given DW, with the higher of the activation energies only measured at higher temperatures. Depending on the specific sample, the higher activation energy is found above 160 °C to 230 °C. This suggests, in turn, that more than one type of defect/polaron is involved, and that the dominant transport mechanism changes with increasing temperature. First principles atomistic modeling suggests that the conductivity of inclined domain walls cannot be solely explained by the formation of a 2D carrier gas and must be supported by hopping processes. This holds true even at temperatures as high as 400 °C. Our investigations underline the potential to extend DW current based nanoelectronic and sensor applications even into the so-far unexplored temperature range up to 400 °C."}],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2025","date_created":"2025-09-17T16:18:18Z","publisher":"Elsevier BV","title":"Demonstration of domain wall current in MgO-doped lithium niobate single crystals up to 400°C","type":"journal_article","status":"public","department":[{"_id":"15"},{"_id":"288"},{"_id":"623"}],"user_id":"22501","_id":"61338","article_type":"original","article_number":"116949","publication_identifier":{"issn":["0167-2738"]},"publication_status":"published","intvolume":"       429","citation":{"ama":"Wulfmeier H, Yakhnevych U, Boekhoff C, et al.

The macroscopic properties of ferroelectrics highly depend on the structure of the underlying ferroelectric domains, which within mixed crystals can interact with the local changes in chemical compositions. In this work, we demonstrate how ferroelectric domain walls can unambiguously be identified and distinguished from local changes in composition by correlating piezoresponse force microscopy with second harmonic generation microscopy, using the Cherenkov contrast, reference crystal contrast, and negative phase mismatching contrast. We demonstrate how measuring the associated intensity change when approaching negative phase mismatching can be used to deduce the local tantalum concentration fast and over a large sample area. Based on these results, we study the natural domain structures that appear from Czochralski-grown, multi-domain LNT solid solution crystals. The developed results and methods serve as the central foundation to poling these mixed crystal systems and are key for their integration and applications.</jats:p>"}],"publication":"Journal of Applied Physics","title":"Second harmonic generation contrasts of ferroelectric domain structures and composition in lithium niobate–tantalate mixed crystals","publisher":"AIP Publishing","date_created":"2025-09-17T16:16:04Z","year":"2025","quality_controlled":"1","issue":"3","article_number":"034101","funded_apc":"1","_id":"61337","department":[{"_id":"15"},{"_id":"623"}],"user_id":"22501","status":"public","type":"journal_article","doi":"10.1063/5.0276183","main_file_link":[{"open_access":"1","url":"https://pubs.aip.org/aip/jap/article/138/3/034101/3352909"}],"oa":"1","date_updated":"2025-09-17T16:18:02Z","volume":138,"author":[{"first_name":"Boris","full_name":"Koppitz, Boris","last_name":"Koppitz"},{"first_name":"Tanya","full_name":"Saxena, Tanya","last_name":"Saxena"},{"first_name":"Felix","full_name":"Bernhardt, Felix","last_name":"Bernhardt"},{"first_name":"Steffen","full_name":"Ganschow, Steffen","last_name":"Ganschow"},{"first_name":"Simone","full_name":"Sanna, Simone","last_name":"Sanna"},{"id":"22501","full_name":"Rüsing, Michael","orcid":"0000-0003-4682-4577","last_name":"Rüsing","first_name":"Michael"},{"first_name":"Lukas M.","full_name":"Eng, Lukas M.","last_name":"Eng"}],"intvolume":"       138","citation":{"ieee":"B.

Since un-\r\nderstanding depends on the explainee’s back-\r\nground and needs, recent research focused on\r\nco-constructive explanation dialogues, where\r\nan explainer continuously monitors the ex-\r\nplainee’s understanding and adapts their expla-\r\nnations dynamically. We investigate the ability\r\nof large language models (LLMs) to engage as\r\nexplainers in co-constructive explanation dia-\r\nlogues. In particular, we present a user study in\r\nwhich explainees interact with an LLM in two\r\nsettings, one of which involves the LLM being\r\ninstructed to explain a topic co-constructively.\r\nWe evaluate the explainees’ understanding be-\r\nfore and after the dialogue, as well as their\r\nperception of the LLMs’ co-constructive behav-\r\nior. Our results suggest that LLMs show some\r\nco-constructive behaviors, such as asking ver-\r\nification questions, that foster the explainees’\r\nengagement and can improve understanding of\r\na topic. However, their ability to effectively\r\nmonitor the current understanding and scaffold\r\nthe explanations accordingly remains limited."}],"user_id":"50995","_id":"61333","language":[{"iso":"eng"}],"file_date_updated":"2025-09-17T14:34:55Z","ddc":["000"]}]
