The paper says many 3D MRI transformer models hit an accuracy ceiling not because they need more data, but because their internal features collapse into a few dominant patterns.
A benchmark evaluates ECG representations across eight public datasets and ten tasks, including tests on unfamiliar data distributions. The accompanying xECG model provides a reference for broader foundation-model comparisons.
This CT benchmark examines tumour-detection performance across patient groups and imaging conditions. Its subgroup analyses illustrate why average scores can conceal weaknesses relevant to deployment.
Researchers describe a battery-free sweat sensor that measures several biomarkers and restores its sensing surface electrically. The work connects wearable engineering with the challenge of sustained measurements outside the laboratory.
