Probabilistic Risk Stratification and Transition-Sensitive Explainability for Attorney Involvement in Workers' Compensation Claims

This study utilizes a CatBoost classifier on 48,130 workers' compensation claims to model attorney involvement as a probabilistic risk process, demonstrating how litigation drivers shift across low-, medium-, and high-risk tiers and revealing asymmetric feature patterns near regime boundaries to enhance risk stratification and explainability.

Reverse-Engineering Radiation Oncology: A Reproducible Pipeline for Affiliation Disambiguation and Author Localisation in the Medical Sciences

This paper presents a reproducible, field-agnostic pipeline that improves the accuracy of author location and seniority assignment in radiation oncology by deriving data directly from raw affiliation strings rather than relying on error-prone institutional tags, achieving significantly higher precision (F1 ≈ 0.92) than standard baselines.

The name-collision burden of name-based author attribution is unequal across name origins: a measurement in OpenAlex, and an identifier-based remedy (SigmaCV)

This study quantifies the significantly higher burden of name collisions faced by East-Asian researchers compared to their Anglophone and Other counterparts within the OpenAlex database, demonstrating that name-based attribution is inherently unequal and advocating for the adoption of identifier-based solutions like SigmaCV to ensure fair research assessment.

Neural Networks for net survival estimation and prediction

This paper introduces a machine learning approach using an adapted Partial Logistic Artificial Neural Network (PLANN) to estimate and predict net survival, demonstrating its flexibility in handling complex data structures compared to traditional spline-based regressions while noting higher variance in estimates for smaller sample sizes and providing the `survivalPLANN` R package for implementation.

Tracking Structural Evolution in Higher Education Mobility -- A Comparative Analysis of Graph Distance Metrics (Hungary, 2006--2024)

This study introduces a graphon-based framework to analyze the structural evolution of Hungary's higher education mobility networks from 2006 to 2024, demonstrating that spectral and distributional distance metrics outperform traditional statistics in capturing policy-induced shifts and revealing hierarchical network tiers.
