  text: "This paper develops and discusses a residual-based a posteriori error\r\nestimate
    and a space--time adaptive algorithm for solving parabolic surface\r\npartial
    differential equations on closed stationary surfaces. 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."

  text: Controlling the intensity of emitted light and charge current is the basis
    of transferring and processing information1. 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.

  text: "Android applications collecting data from users must protect it according
    to the current legal frameworks. 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. "

  text: Knowledge graphs (KGs) differ significantly over multiple different versions
    of the same data source. 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.

abstract:
- lang: eng
  text: Dialects introduce syntactic and lexical variations in language that occur
    in regional or social groups. 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.
