Inequalities between Dirichlet and Neumann eigenvalues of the Laplacian and of other differential operators have been intensively studied in the past decades. The aim of this paper is to introduce differential forms and the de Rham complex in the study of such inequalities. We show how differential forms lie hidden at the heart of the work of Rohleder on inequalities between Dirichlet and Neumann
Rewetting is widely promoted as a climate mitigation strategy to preserve soil carbon in drained wetlands, although rewetting may enhance methane production and corresponding emissions. The increase in methane emissions following rewetting might be underestimated without considering near-surface methane oxidation under a fluctuating water table. Here, we refined the methane module in Lund-Potsdam-
This review examines how coordination is infrastructured in digital health ecosystems where technologies, institutions, and practices intersect across organisational and professional boundaries. Drawing on a systematic analysis of the literature, we identify three interdependent infrastructural layers: technological, informational, and institutional, and four recurring processes through which coor
Abstract in GermanIn dieser Folge spricht Maria del Carmen Moreno Escobar mit Florian Hermann und Adrian Kinzig über ihre Forschung zu römischer Landschaft, Mobilität und Connectivity. Sie zeigt, wie GIS, Fernerkundung und geoarchäologische Methoden helfen, antike Häfen, Verkehrswege und Interaktionsräume zu rekonstruieren – und wie sich historische und archäologische Daten zu einem vielschichtigeIn this episode, Maria del Carmen Moreno Escobar speaks with Florian Hermann and Adrian Kinzig about her research on Roman landscape, mobility, and connectivity. She demonstrates how GIS, remote sensing, and geoarchaeological methods help reconstruct ancient ports, transport routes, and spaces of interaction—and how historical and archaeological data can be combined to create a multifaceted pictur
Microalgae emit volatile organic compounds (VOCs) that can profoundly impact climate by leading to new particle formation and influencing clouds. Among these VOCs, dimethyl-sulphide (DMS) is of particular interest due to its key role in atmospheric processes. Despite its importance, many detailed processes linking microalgae and sea-atmosphere interactions remain poorly understood. We investigated
This introductory essay explains the motivation behind this collection and provides summaries of the individual contributions to this volume. Bernard Williams is often regarded as a merely negative or critical philosopher, with no distinctive philosophical approach of his own. This perspective ignores Williams’s efforts to make positive contributions to several areas in ethics and metaethics, incl
This chapter provides an overview of the different optical sectioning methods that enable performing three dimensional (3D) imaging of possibly complex samples. It discusses their benefits and limitations regarding their penetration depth, their imaging speed, their photo-toxic effect or their complexity. Focusing on fluorescence imaging, the chapter dives into approaches that make it possible to
Deoxyhypusine synthase (DHS) catalyzes the rate-limiting step of hypusination, a unique post-translational modification of eukaryotic translation factor 5 A (eIF5A). While DHS activity plays a critical role in both normal cellular processes and disease development, the lack of specific molecular tools has hindered detailed studies of this enzyme and the hypusination pathway in general. Existing in
Articles pose a particular challenge to second-language learners whose first language does not have them. Variability in article production in these learners is often explained in terms of first-language influence, but there are also suggestions that frequency-biased regularities in the target language itself might play a role. While most second-language research on articles has focused on English
While Generative Artificial Intelligence (GAI), particularly tools powered by Large Language Models (LLMs), offer benefits in teaching and learning, they also raise critical concerns about academic integrity, fairness in examinations d ue to their potential for generating educational content. This evolving landscape requires higher education institutions to rethink their assessment models, ensurin
Rapidly evolving academic and professional environments require essential skills such as communication, collaboration, creativity and critical thinking, which are not typically learned and assessed explicitly in formal education. These skills encompass a significant part of the competencies and are increasingly valued in an AI-driven workforce because they cannot be easily replicated by machines.

Age estimation based on the dentition of animal remains is one of the most important methods used for analysis of the demography of past as well as contemporary animal populations by zooarchaeologists and wild game biologists (Wagenknecht 1967; Silver 1969; Morris 1972; Wilson et al. 1982). By constructing age profiles from faunal remains it is possible to study hunting of wild boar and pig husban
