Background Aggregation of amyloid-β (Aβ) and tau is central to Alzheimer’s disease (AD) pathogenesis and forms the basis of established cerebrospinal fluid (CSF) and imaging biomarkers. However, increasing evidence suggests that AD involves systemic processes beyond the central nervous system. [...]

We want to tell you a story about JuPedSim, a pedestrian dynamics simulator. It is a story about success, failure and renewal. [...]

High-performance computing (HPC) applications often suffer from performanceissues such as communication overhead, synchronization delays, load imbalance,serialization, etc., which are traditionally identified through manual and expert-driven analysis of profiling data. This work investigates the utility of large lan-guage models (LLMs) for analyzing performance problems in parallel programswith load imbalance analysis as a representative use case.To explore the use of Large Language Models (LLM) in parallel applications,structured performance data is extracted from CubeGUI (a GUI that displays per-formance data for parallel programs including MPI and OpenOpenMP applica-tions). [...]

The search for superionic conductors requires a deep understanding of the underlying crystal structure and local dynamic processes. Therefore, cationic and anionic substitutions are typically performed to monitor the resulting changes in the structure and ionic transport, ultimately drawing conclusions to find optimized $Li^+$ conductors. [...]

Multiple properties of materials and energy devices are linked by known physical relationships, yet machine-learning models commonly predict each property independently from descriptors, here termed Direct prediction. This study tests whether these relationships remain useful when their inputs are themselves model predictions. [...]

Efficient solid-electrolyte discovery requires a tractable, interpretable link between composition, structure and ion transport despite sparse datasets. Here, intrinsic lattice formation strain (ILFS) is introduced to provide a reduced, family-referenced structural coordinate defined by the relative volumetric deviation between an experimentally refined structure and a symmetry-limited virtual reference. [...]

Non-Arrhenius ion transport is increasingly observed in solid electrolytes but remains difficult to compare across materials or use in screening. A curated database of 867 conductivity-temperature entries from thio-LISICON and LGPS-type sulfides is used to introduce Meyer-Neldel deviation (MND), a physics-informed, material-level descriptor of temperature-dependent changes in apparent activation energy.
