Researchers have created a heavy-atom-free, twisted D–A–A–D molecule that self-assembles into crystalline nanofibers. These fibers show high light absorption and 72% singlet oxygen yield, enabling rapid visible-light-driven photooxidation. They are easily recovered by sedimentation and remain stable over multiple cycles, offering a new design for efficient, reusable solid-state photosensitizers.

Researchers deliver the first comprehensive survey and open NNLCB benchmark of neural universal lossless compressors, taxonomizing 17 state-of-the-art static/adaptive/semi-adaptive algorithms tested across 8.5 GB of multi-source data on CPUs/GPUs.

EduStudio unifies Cognitive Diagnosis and Knowledge Tracing in a modular PyTorch library, cutting new-model code to templated inheritance and offering live leaderboards at edustudio.ai.

ECG-I2S, an open-source Python toolkit, turns smartphone photos of printed ECGs into beat-aligned digital signals and real-time cardiac diagnoses via a one-line pip install.
