Mesoscale FEM Model of Concrete: Statistical Assessment of Inherent Stress Concentrations in Dependence on Phase Heterogeneity
Concrete heterogeneity originates from its production process, which involves bonding aggregates with a binder matrix. This study presents a mesoscale finite element model (MFEM) that offers detailed insights into the fracture process at the aggregate-cement matrix interface, focusing on one of concrete's key properties: its mechanical response. Unlike discrete models, which often average out critical stress concentrations within the mesostructure, the MFEM approach captures detailed stress dis…

Regression-Based Approach to Anxiety Estimation of Spider Phobics During Behavioural Avoidance Tasks
Phobias significantly impact the quality of life of affected persons. Two methods of assessing anxiety responses are questionnaires and behavioural avoidance tests (BAT). While these can be used in a clinical environment they only record momentary insights into anxiety measures. In this study, we estimate the intensity of anxiety during these BATs, using physiological data collected from unobtrusive, wrist-worn sensors. Twenty-five participants performed four different BATs in a single session,…

From Black Boxes to Transparent Minds: Evaluating and Enhancing the Theory of Mind in Multimodal Large Language Models
As large language models evolve, there is growing anticipation that they will emulate human-like Theory of Mind (ToM) to assist with routine tasks. However, existing methods for evaluating machine ToM focus primarily on unimodal models and largely treat these models as black boxes, lacking an interpretative exploration of their internal mechanisms. In response, this study adopts an approach based on internal mechanisms to provide an interpretability-driven assessment of ToM in multimodal large …

Gold-Standard Chemical Database 138 (GSCDB138): A diverse set of accurate energy differences for assessing and developing density functionals
We present GSCDB138, a rigorously curated benchmark library of 138 data sets (8383 entries) covering main-group and transition-metal reaction energies and barrier heights, non-covalent interactions, dipole moments, polarizabilities, electric-field response energies, and vibrational frequencies. Legacy data from GMTKN55 and MGCDB84 have been updated to today's best reference values; redundant, spincontaminated, or low-quality points were removed, and many new, property-focused sets were added. T…

inrep: A Comprehensive Framework for Adaptive Testing in R
The inrep package provides a comprehensive framework for implementing computerized adaptive testing (CAT) in R. Building upon established psychometric foundations from TAM, the package enables researchers to deploy production-ready adaptive assessments through an integrated shiny interface. The framework supports all major item response theory models (1PL, 2PL, 3PL, GRM) with real-time ability estimation, multiple item selection algorithms, and sophisticated stopping criteria. Key innovations i…

Assessing the Prevalence of AI-assisted Cheating in Programming Courses: A Pilot Study
Tools that can generate computer code in response to inputs written in natural language, such as ChatGPT, pose an existential threat to Computer Science education in its current form, since students can now use these tools to solve assignments without much effort. While that risk has already been recognized by scholars, the proportion of the student body that is incurring in this new kind of plagiarism is still an open problem. We conducted a pilot study in a large CS class (n=120) to assess th…

Day 18
Today I debugged an issue with accessing backend endpoints from a Next.js frontend talking to a NestJS API.
The browser was blocking requests due to a CORS error — the Authorization header was not allowed in the preflight response. Even though frontend domains were correctly set, I forgot to include Authorization in allowedHeaders.
After updating enableCors() to:
`allowedHeaders: 'Authorization, Content-Type, Accept'`
…the issue disappeared, and t…

From a Different Star: 3I/ATLAS in the context of the Ōtautahi-Oxford interstellar object population model
The discovery of the third interstellar object (ISO), 3I/ATLAS (`3I'), provides a rare chance to directly observe a small body from another Solar System. Studying its chemistry and dynamics will add to our understanding of how the processes of planetesimal formation and evolution happen across the Milky Way's disk, and how such objects respond to the Milky Way's potential. In this Letter, we present a first assessment of 3I in the context of the Ōtautahi-Oxford model, which uses data from Gaia…
