A similar conclusion was drawn from optical videos, where the plants were injured and the milky fluid was stretched (sometimes forming fibers) after the cut. Rapid solidification cannot be explained with physical drying because physical drying is transport-limited and therefore is inherently slow. It can, however, be explained with coagulation being triggered by a sudden decrease in hydrostatic pressure. A mechanism based on a pressure drop is corroborated by optical videos of both plants being injured under water. While the liquid exuded by E. characias keeps streaming away, the liquid exuded by C. glomerata quickly forms a plug even under water. Presumably, the pressure drop causes an influx of serum into the laticifers. The serum, in turn, triggers a transition from a liquid–liquid phase separated state (an LLPS state) of a resin and hardener to a single-phase state. QCM measurements, optical videos, and cryo-SEM images suggest that LLPS plays a role in the solidification of C. glomerata."}],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["2223-7747"]},"publication_status":"published","intvolume":" 14","citation":{"short":"A.

The study focused on determining the adsorption kinetics, viscoelastic properties, and electroresponsivity of polyelectrolyte layers. For the first time, it was demonstrated that the structure (compact or expanded) of the layers can be determined by electroresponsivity. Viscoelastic modeling alone did not provide a conclusive answer as to whether the layers were compact or expanded. The study was further enriched by streaming potential and contact angle measurements, where polyelectrolyte multilayers were formed on mica. It was found that successive adsorption of layers led to periodic inversion of the zeta potential. Systematic differences were observed between the different top layers, which were explained by intermixing between layers. The presence or absence of interpenetration, as determined by the measurements of streaming potential and contact angles, correlated well with electroresponsivity.","lang":"eng"}]},{"year":"2025","intvolume":" 27","page":"19733-19747","citation":{"chicago":"Leppin, Christian, Arne Langhoff, and Diethelm Johannsmann. “A Fast Electrochemical Quartz Crystal Microbalance (EQCM) Evidences the Presence of Nanobubbles in Alkaline Water Splitting.” Physical Chemistry Chemical Physics 27, no. 37 (2025): 19733–47. https://doi.org/10.1039/d5cp02691a.","ieee":"C.

The minimal dimension of such a representation is the \\emph{linear dimension of the group action} and this has applications in cryptography and cryptosystems.\r\n\r\nWe develop the idea of linear dimension from an algebraic point of view by using the theory of permutation modules. We give structural results about representations of minimal dimension and investigate the implications of faithfulness, transitivity and primitivity on the linear dimension. Furthermore, we compute the linear dimension of several classes of finite primitive permutation groups. We also study wreath products, allowing us to determine the linear dimension of imprimitive group actions. Finally, we give the linear dimension of almost simple finite $2$-transitive groups, some of which may be used for further applications in cryptography. Our results also open up many new questions about linear representations of group actions."}],"status":"public"},{"article_type":"original","department":[{"_id":"175"}],"user_id":"21765","_id":"62906","status":"public","type":"journal_article","doi":"10.3224/fug.v5i2.02","volume":5,"author":[{"last_name":"Riedl","full_name":"Riedl, Lars","id":"31513","first_name":"Lars"},{"first_name":"Heiko","full_name":"Meier, Heiko","id":"21765","last_name":"Meier"}],"date_updated":"2025-12-19T15:53:01Z","intvolume":" 5","page":"97 - 119","citation":{"apa":"Riedl, L., & Meier, H.

Despite the simplicity of the process’s setup, the thermomechanical loads and high relative velocities involved, especially in the contact zone, make the application of classical methods for characterising friction inaccurate. It is therefore essential to find a way to describe the frictional behaviour under real process conditions to be able to gain a holistic understanding of the process and the effect of the adjustable parameters on the outcome, especially the temperature. To achieve this goal, an experimental setup that considers the actual process boundary conditions in forming tubes made of EN AW-6060 was used to measure in situ normal and frictional forces, in addition to process temperatures, under varying rotational speed and feed rate values."}],"publication":"Journal of Manufacturing and Materials Processing","type":"journal_article","doi":"10.3390/jmmp9090302","title":"In Situ Investigation of the Frictional Behaviour in Friction-Spinning","volume":9,"author":[{"last_name":"Wiens","full_name":"Wiens, Eugen","id":"7888","first_name":"Eugen"},{"last_name":"Hijazi","full_name":"Hijazi, Dina","first_name":"Dina"},{"full_name":"Jüttner, Maik","last_name":"Jüttner","first_name":"Maik"},{"first_name":"Werner","id":"233","full_name":"Homberg, Werner","last_name":"Homberg"},{"first_name":"Mark Dennis","full_name":"Kensy, Mark Dennis","last_name":"Kensy"},{"last_name":"Tillmann","full_name":"Tillmann, Wolfgang","first_name":"Wolfgang"}],"date_created":"2025-12-19T10:05:03Z","publisher":"MDPI AG","date_updated":"2025-12-22T10:39:34Z","intvolume":" 9","citation":{"ama":"Wiens E, Hijazi D, Jüttner M, Homberg W, Kensy MD, Tillmann W.

As the matrix dimension grows, the law of large numbers and the central limit theorem for the number of real eigenvalues are well understood, but the probabilities of rare events remain largely unexplored. Large deviation type results have been obtained only in extreme cases, when either a vanishingly small proportion of eigenvalues are real or almost all eigenvalues are real. Here, in both the strong and weak asymmetry regimes, we derive the probabilities of rare events in the moderate-to-large deviation regime, thereby providing a natural connection between the previously known regime of Gaussian fluctuations and the large deviation regime.

We describe this limit distribution $μ_t$ as a function of the time parameter $t$ of the heat evolution: For small time, zeros start to spread out in approximately semicircular distributions, then intricate curves start to form and merge, until for large time, the zero distribution approaches a widespread semicircle law through the initial center of mass. The Stieltjes transform of the limit distribution $μ_t$ satisfies a self-consistent equation and a Burgers' equation.

This assessment gap is addressed in this thesis by developing and validating a role-play-based simulation (RobS) designed for the summative assessment of pre-service EFL teachers' feedback competence on writing. Drawing on theories from multiple disciplines, such as higher education, medical education, teacher education, educational psychology, and EFL-specific didactics, the RobS is developed as a performance-oriented assessment format. In the RobS, pre-service EFL teachers engage in a feedback conversation with trained actors who portray a standardized learner. Following an argument-based approach to validation, the extent to which the RobS can be considered valid is investigated. Data from multiple studies, focusing on aspects such as authenticity, fairness, reliability, and external validity, are presented. The discussion in the validity argument indicates that the RobS can elicit and assess the performative facet of feedback competence on writing with sufficient confidence. This work contributes a novel, empirically supported assessment framework to teacher education research. Moreover, it presents an approach to address the assessment gap, enabling pre-service EFL teachers to show how they provide feedback, rather than just tell their lecturers about it."}]}]
