• Inherent uninterruptible power supply via directly grid-connected machines and variable inertia flywheels

  Rettig, A., Jahromi, S. N., Jauch, C., & Reese, L. (2026). Inherent uninterruptible power supply via directly grid-connected machines and variable inertia flywheels. Electric Power Systems Research, 256, 11. http://doi.org/https://doi.org/10.1016/j.epsr.2026.112880 (Original work published 2026)

  This paper analyses the potential of a novel hydraulic variable inertia flywheel to improve standby power systems when attached to directly grid-connected electrical machines. Conventional standby power systems often require several seconds to reach full operation after a grid outage. During this time, critical loads may be left without power, unless supported by an additional uninterruptible power supply system. By flange-mounting a hydraulic variable inertia flywheel to an existing grid-connected electrical machine, emergency power can be provided immediately without the need for power electronics. The ability of the hydraulic variable inertia f lywheel to discharge at a quasi-constant speed offers improved frequency and voltage stability. The performance of the hydraulic variable inertia flywheel is compared with traditional flywheels of equivalent inertia and energy content across the two most common machines. The simulation results identify the most appropriate machine- f lywheel configuration to complement standby power systems. Combining a hydraulic variable inertia f lywheel with an electrically excited synchronous machine provides the most stable voltage and frequency support. The application of the widely used induction machine is found to be not preferable. Beyond acting as supplementary technology for standby power systems, combining directly grid-connected electrical machines with flywheels also offers secondary and tertiary benefits.

• SonoGame – more than just a game: Evaluation of an ultrasound training platform

  Guergan, S., Henze, V., Gall, C., Schönfisch, B., Brucker, S. Y., Bertel, S., … Hahn, M. (2026). SonoGame – more than just a game: Evaluation of an ultrasound training platform. European Journal of Ultrasound, 47(02), 171–179. http://doi.org/10.1055/a-2627-8194

  Ultrasound examination is a vital imaging tool in medicine, yet opportunities for comprehensive theoretical and practical training during medical education are limited. Effective ultrasound education requires both theoretical knowledge and hands-on practice. To address this, we developed SonoGame, a gamified platform designed to teach ultrasound skills to medical students. SonoGame provides a step-by-step introduction to ultrasound imaging and aims to improve skills such as image orientation, spatial visualization, and hand-eye-coordination through mini-games using geometric objects. This study evaluates the impact of SonoGame training on ultrasound skills.In this prospective, single-center study, 56 medical students, the majority of whom had no prior ultrasound experience, were randomly assigned to either a control group or a SonoGame group. The SonoGame group trained with the platform in four 30-minute sessions over 4 weeks, while the control group received no training. Ultrasound skills were assessed in both groups before and after the training period.The SonoGame group showed significant improvement in ultrasound skills, particularly with complex anatomical structures, compared to the control group. Participants in the SonoGame group also reported increased familiarity and confidence with sonography, viewing SonoGame as a valuable tool in their training.SonoGame is an effective supplement to conventional ultrasound education, enhancing the skills necessary for ultrasound examinations in medical students.

  This paper synthesizes insights from a scoping workshop funded by the Volkswagen Foundation that focused on reading competencies in the digital age. The purpose of the workshop was to discuss the current state of research, identify actionable next steps and outline considerations for future work in the context of learning to read in a digital world. The conference brought together German researchers with a wide range of backgrounds and expertise in reading research including computer science, psychology, language processing and educational science. Presentations and discussions during the conference centred broadly on potentials and challenges of learning to read and reading support in the context of digitalization—focusing on issues related to artificial intelligence and app-based learning. Results of the workshop and subsequent writing sessions include a synthesis of key considerations and core questions for the field of research on digital approaches to support reading. Findings highlight the need for the field at large to identify and develop digital tools for diagnosing readers’ abilities and providing them with the support they need, and to do so with increased interdisciplinary collaboration, open science practices and communication among scholars.

• Seeing the invisible: Enhancing radiation protection competencies through a curricular virtual reality simulation in medical education

  Dabel, J., Meier, N., Süncksen, M., Mayer, L., Zak, G., Teistler, M., … Junga, A. (2026). Seeing the invisible: Enhancing radiation protection competencies through a curricular virtual reality simulation in medical education.

  Background: Radiation protection remains abstract in medical training as ionizing radiation is not perceptible to human senses. Theoretical instruction often fails to bridge the gap to safe clinical behavior in the operating room. This study evaluates a newly developed, curricular virtual reality (VR) course designed to visualize scatter radiation and improve medical students’ safety-related self-efficacy.

  Methods: In a prospective study at the University of Münster (winterterm 2025/26), a VR radiation protection module was implemented as a mandatory curricular component for 169 third-year medical students. Data from 139 students who provided written informed consent were included in the evaluation. The core intervention consisted of an immersive VR simulation featuring a virtual operating room with a C-arm based on the proof-of-concept by Süncksen et al. [1] and was specifically adapted for this course. Scatter radiation was rendered as real-time 3D heatmap. Evaluation was conducted via pre- and post-intervention surveys (5-point Likert scales), including the NASA Task Load Index (NASA-TLX) to assess mental demand and frustration. Statistical analysis presented in mean (M)±SD, utilized paired samples t-tests and Cohen’s d.

  Results: The module achieved a global rating of 71.2±21.7 (scale 1-100). Students reported high immersion (M=3.6±0.9) and enjoyment (M=4.1±1.0) with low physical demand (M=1.7±0.9). NASA-TLX scores indicated moderate mental demand (M=2.4±1.1) and task complexity (M=2.5±0.9), suggesting a well-balanced challenge. Comparisons of self-assessment scores in the pre- and post-intervention questionnaires revealed significant improvements across all competency domains (p<0.001). The most pronounced effect was observed for safe positioning within the room (d=1.1; pre: M=2.3±1.0, post: M=3.3±0.9). Overall, 91.7% of students recommended the permanent integration of the VR course.

  Discussion: Virtual reality effectively bridges the gap between theory and practice by rendering invisible radiation hazards visible. The immersive 3D heatmap enables students to experience spatial dose distributions, transforming abstract safety principles into tangible experiences. Our results align with prior research [2], while highlighting the specific impact of high-fidelity heatmaps on spatial awareness. NASA-TLX data confirm the simulation is intellectually stimulating without inducing excessive cognitive demand, ensuring feasibility for mandatory curricular use. Building on institutional VR-expertise [3], this module can help to establish a scalable educational standard that effectively prepares students for radiation-safe behavior in clinical practice.

  Take-home messages: Immersive 3D heatmaps significantly enhance student self-efficacy in radiation-safe positioning. The balanced cognitive load and high student acceptance made this scalable VR module a useable approach for risk-free practical training.

• Intratumoral distribution of anisokaryosis in canine cutaneous mast cell tumors

  Abstract

  anzeigen ▸

  Automated measurements of anisokaryosis in canine cutaneous mast cell tumors (ccMCTs) have been shown to be predictive of survival, but questions remain regarding the intratumoral distribution of anisokaryosis. Whole-slide images of 96 ccMCTs were analyzed with a deep learning-based segmentation algorithm to quantify anisokaryosis using the standard deviation (SD) of the nuclear area. In 35/96 cases, \textgreater5\% of the non-overlapping 256 × 256 µm 2 regions were hotspots (SD ≥11.5 µm 2 ). Regions selected by 7 pathologists within these 35 cases matched hotspots in 32\% of the instances. Outcome analysis (tumor-related death) based on single tumor regions yielded an area under the curve (AUC) of 0.901 for pathologist-selected hotspots, falling between random region selection (AUC: 0.862) and 90th-percentile targeted selection (AUC: 0.956). Whole-slide analysis of the hotspot proportion predicted survival with an AUC of 0.956, with 20\% of hotspots as a prognostically meaningful threshold. Whereas pathologists-selected tumor regions are prognostically meaningful for nuclear morphometry, whole-slide analysis may provide additional prognostic information.

• Fatigue Life Evaluation of a Wind Turbine Tower with a Hydraulic-Pneumatic Flywheel System in the Rotor

  Goga, A., Jauch, C., Lippke, A., & Gagel, A. (2026). Fatigue Life Evaluation of a Wind Turbine Tower with a Hydraulic-Pneumatic Flywheel System in the Rotor. In TORQUE Conference 2026. Bruges, Belgium: IOP: Journal of Physics. http://doi.org/10.1088/1742-6596/3224/9/092001 (Original work published Mai 2026)

  Abstract

  This study investigates the effectiveness of a hydraulic-pneumatic flywheel system integrated into the rotor of a wind turbine for structural load reduction. The analysis uses the state-of-the-art aeroelastic simulation tools OpenFAST and HAWC2, coupled with a novel Simulink based flywheel and control model, to evaluate fatigue loads mitigation abilities of the flywheel. Fatigue load simulations are performed for cases with and without the flywheel system, with a specific focus on the fatigue life of the tower. The findings indicate that different flywheel control functionalities exhibit varying levels of influence on tower fatigue loading in both simulation environments. A fatigue-life extension of up to 20% is achieved, demonstrating the potential of flywheel control strategies for structural load mitigation.
