The full\r\ndiscretization uses the surface finite element method in space and the backward\r\nEuler method in time. The proposed error indicator bounds the error quantities\r\nglobally in space from above and below, and globally in time from above and\r\nlocally from below. A space--time adaptive algorithm is proposed using the\r\nderived error indicator. Numerical experiments illustrate and complement the\r\ntheory."}],"citation":{"ieee":"B. Kovács and M. F. R.

By contrast, robust information storage and magnetic random-access memories are implemented using the spin of the carrier and the associated magnetization in ferromagnets2. The missing link between the respective disciplines of photonics, electronics and spintronics is to modulate the circular polarization of the emitted light, rather than its intensity, by electrically controlled magnetization. Here we demonstrate that this missing link is established at room temperature and zero applied magnetic field in light-emitting diodes2,3,4,5,6,7, through the transfer of angular momentum between photons, electrons and ferromagnets. With spin–orbit torque8,9,10,11, a charge current generates also a spin current to electrically switch the magnetization. This switching determines the spin orientation of injected carriers into semiconductors, in which the transfer of angular momentum from the electron spin to photon controls the circular polarization of the emitted light2. The spin–photon conversion with the nonvolatile control of magnetization opens paths to seamlessly integrate information transfer, processing and storage. Our results provide substantial advances towards electrically controlled ultrafast modulation of circular polarization and spin injection with magnetization dynamics for the next-generation information and communication technology12, including space–light data transfer. The same operating principle in scaled-down structures or using two-dimensional materials will enable transformative opportunities for quantum information processing with spin-controlled single-photon sources, as well as for implementing spin-dependent time-resolved spectroscopies."}],"extern":"1","date_created":"2025-04-23T13:27:27Z","type":"journal_article","keyword":["Lasers","LEDs and light sources","Spintronics"],"department":[{"_id":"977"}],"status":"public","page":"783-788","publisher":"Springer Science and Business Media LLC","_id":"59663","user_id":"15911","volume":627,"citation":{"ieee":"P.

Such data protection has become even more important since the European Union rolled out the General Data Protection Regulation (GDPR). Since app developers are not legal experts, they find it difficult to write privacy-aware source code. Moreover, they have limited tool support to reason about data protection throughout their app development process.\r\nThis paper motivates the need for a static analysis approach to diagnose and explain data protection in Android apps. The analysis will recognize personal data sources in the source code, and aims to further examine the data flow originating from these sources. App developers can then address key questions about data manipulation, derived data, and the presence of technical measures. Despite challenges, we explore to what extent one can realize this analysis through static taint analysis, a common method for identifying security vulnerabilities. This is a first step towards designing a tool-based approach that aids app developers and assessors in ensuring data protection in Android apps, based on automated static program analysis.

They also often contain blank nodes that do not have a constant identifier over all versions. Linking such blank nodes from different versions is a challenging task. Previous works propose different approaches to create signatures for all blank nodes based on named nodes in their neighborhood to match blank nodes with similar signatures. However, these works struggle to find a good mapping when the difference between the KGs’ versions grows too large. In this work, we propose Blink, an embedding-based approach for blank node linking. Blink merges two KGs’ versions and embeds the merged graph into a latent vector space based on translational embeddings and subsequently matches the closest pairs of blank nodes from different graphs. We evaluate our approach using real-world datasets against state-of-the-art approaches by computing the blank node matching for isomorphic graphs and graphs that contain triple changes (i.e., added or removed triples). The results indicate that Blink achieves perfect accuracy for isomorphic graphs. For graph versions that contain changes, such as having up to 20% of triples removed in one version, Blink still produces a mapping with an Optimal Mapping Deviation Ratio of under 1%. These results show that Blink leads to a better linking of KGs over different versions and similar graphs adhering to the linked data guidelines."}],"date_created":"2025-09-11T10:19:47Z","department":[{"_id":"574"}],"type":"book_chapter","conference":{"name":"ISWC 2024: : The 23ed International Semantic Web Conference","start_date":"2024-11-11","location":"Baltimore, USA","end_date":"2024-11-15"},"status":"public","_id":"61210","publisher":"Springer Nature Switzerland","user_id":"67234","citation":{"ieee":"A.

Most NLP methods are not sensitive to such variations. This may lead to unfair behavior of the methods, conveying negative bias towards dialect speakers. While previous work has studied dialect-related fairness for aspects like hate speech, other aspects of biased language, such as lewdness, remain fully unexplored. To fill this gap, we investigate performance disparities between dialects in the detection of five aspects of biased language and how to mitigate them. To alleviate bias, we present a multitask learning approach that models dialect language as an auxiliary task to incorporate syntactic and lexical variations. In our experiments with African-American English dialect, we provide empirical evidence that complementing common learning approaches with dialect modeling improves their fairness. Furthermore, the results suggest that multitask learning achieves state-of-the-art performance and helps to detect properties of biased language more reliably."}],"related_material":{"link":[{"url":"https://github.com/webis-de/acl24-dialect-aware-bias-detection","relation":"software"}]},"_id":"58722","publisher":"Association for Computational Linguistics","page":"9294–9313","editor":[{"full_name":"Ku, Lun-Wei","first_name":"Lun-Wei","last_name":"Ku"},{"full_name":"Martins, Andre","first_name":"Andre","last_name":"Martins"},{"full_name":"Srikumar, Vivek","first_name":"Vivek","last_name":"Srikumar"}],"user_id":"84035","status":"public","place":"Bangkok, Thailand","oa":"1","citation":{"apa":"Spliethöver, M., Menon, S.
