Transporter Interactionsof Methoxyflavones and Their In Vivo PharmacokineticImplications
Abstract Flavonoids are widely consumed dietary polyphenols that modulate drug disposition via membrane transporters. Increasing attention has been paid to methoxyflavones (MeO-FLVs) because methoxylation can increase membrane permeability and metabolic stability, potentially ele...

Carrier Dynamicsin Nonfullerene Acceptor OrganicPhotovoltaics through Ultrafast Spectroscopy
Abstract Nonfullerene acceptors (NFAs) have transformed organic photovoltaics (OPVs) by enabling high efficiencies at small energetic offsets, but rational progress demands a mechanistic view of photoinduced processes across femtosecond–microsecond windows. This review synthesize...

Efficient retrieval-augmented generation via multi-signal token compression
Retrieval-augmented generation (RAG) improves question answering by grounding large language models in retrieved passages, but long contexts increase prompt-token cost and latency. We introduce HLLC, a deterministic, generator-agnostic framework that compresses corpus chunks duri...

Patient-level topology-aware graph transformer for breast histopathology classification
Progress in computational pathology is limited not only by model architecture, but also by evaluation design. In breast histopathology benchmarks such as BreaKHis, multiple correlated image tiles often originate from the same patient; consequently, image-wise splits can inflate p...
