Seven-Day Landslide Forecasting from PCA-Derived InSAR Data with a Random Forest Classifier
Combines PCA-reduced InSAR deformation histories with a random forest to forecast instability seven days ahead. The study asks whether satellite displacement signals can support short-horizon prediction, rather than only retrospective detection.

2.5 CNN: Leveraging 2D CNNs to Pretrain 3D Models in Low-Data Regimes for COVID-19 Diagnosis
Uses 2D CNN pretraining to give a 3D CT model a stronger starting point when labeled volumetric data are scarce. The method was developed for COVID-19 diagnosis, where full 3D training sets are relatively small.

Weak-Form Physics-Informed Neural Networks for Noise-Robust Inverse Problems
Weak-form constraints transfer derivatives from noisy data to smooth test functions, stabilizing inverse parameter recovery on scientific imaging problems where pointwise physics-informed losses amplify noise.

Covert-Channel Forensics of Deceptive Language Models: When Internal-State Monitoring Adds Admissible Evidence
Internal activations add evidence when deceptive or collusive information is hidden from the transcript. When visible behavior already reveals it, white-box probes add much less beyond the behavioral evidence.

Modified-Equation-Informed Solution-Discrepancy Signatures Detect Hidden Stabilization Changes in Convective Heat-Transfer Solvers
Small stabilization changes can leave heat-transfer outputs nearly unchanged even when the solver has changed. Modified-equation signatures reveal those hidden numerical changes directly from the computed solution fields.

Emergence of a Deterministic Butterfly Cone in Structural Glasses
A localized perturbation spreads through a structural glass inside a deterministic butterfly cone. Its speed changes little as structural relaxation slows dramatically, separating information spreading from glassy dynamics.

Predicting and Relocating the Shear Band in a Two-Dimensional Model Glass
The undeformed glass contains enough structural information to predict where its shear band will form. Softening a targeted region before loading can then move the eventual band to a different location.
