This work proposes an open-source, web-based clinical decision support platform to address fragmented outpatient data, inefficient clinician–patient communication, and high follow-up burdens in gestational diabetes management. The platform introduces a novel dual-endpoint architecture that leverages large language models (LLMs) to intelligently aggregate and summarize patients’ extramural health data, providing clinicians with context-aware decision support. Personalized lifestyle guidance and treatment explanations are delivered directly to patients via WhatsApp. Designed with a modular architecture, the system integrates electronic health records and messaging interfaces to significantly enhance clinical oversight and patient adherence, strengthen continuity of care, and reduce the need for in-person follow-ups. Its adaptable framework also holds promise for extension to other chronic disease management contexts.
This work addresses the inefficiency in large language model (LLM) inference caused by excessive computation and communication overhead from low-information tokens. The authors propose Entropy Gate, a novel framework that introduces thermodynamic entropy quenching into LLM token compression. By integrating statistical, structural, and positional features into a multi-factor information energy metric, the method employs adaptive temperature scheduling and Boltzmann-based survival probabilities to dynamically prune low-energy tokens, augmented with semantic fidelity gating and context deduplication. Theoretically, selecting tokens in descending order of information energy maximizes semantic retention and approaches the information-theoretic compression limit. Experiments demonstrate 40–60% compression rates across five prompt types while maintaining semantic similarity (SE > 0.80); with energy-squared amplification and external memory, agent tasks achieve total compression of 88–96%, supporting stateless, model-agnostic deployment.
This work addresses the challenge of balancing privacy preservation and data utility in quantum computing by proposing a geometry-aware differential privacy framework grounded in the spectral structure of quantum Fisher information (QFI). By replacing conventional isotropic noise with direction-dependent perturbations, the method enables optimized allocation of the privacy budget. It introduces a QFI-aligned optimal noise mechanism that elucidates the impact of decoherence basis selection on privacy and establishes a privacy–utility uncertainty relation. Integrating adaptive QFI estimation, subspace projection, and zero-knowledge auditing, the approach is validated on IBM Quantum hardware and Qiskit Aer GPU simulations, achieving a privacy parameter ε ≈ 0.001 at equivalent utility—significantly outperforming classical differential privacy methods (ε ≈ 4800)—and demonstrating, for the first time, the privacy-amplifying potential of intrinsic hardware noise.
