Geometry-Based Description for Hydrogen Bond Organization in Small Water Clusters Derived from Spectroscopic and Quantum Chemical Data

Hydrogen-bond organization plays a central role in determining the structure and properties of water from molecular to macroscopic scales. In this study, we propose a geometry-based descriptor for small hydrogen-bonded water clusters, (H2O)n, with n = 2–6. The central element of...

Performance Analysis of Q-Learning; DQN-Enhanced PID Controllers for Aircraft Trajectory Tracking Under Wind Disturbances

Traditional fixed-gain proportional–integral–derivative (PID) controllers often exhibit limited adaptability when regulating the longitudinal motion of passenger aircraft under varying flight conditions and external disturbances. This study proposes an adaptive control framework...

Non-Compensatory Security and Utility Gates for Blockchain Lifecycle Assessment: Framework Development and an Operational-Energy Application to the Ethereum Merge

Environmental comparisons of blockchain systems are often reduced to electricity per transaction, although operational services also depend on validators, cloud gateways, storage, monitoring, key management, recovery, and hardware replacement. This study develops a lifecycle asse...

Robustness and cross-cohort concordance of developmental regulons in endometrial carcinoma

Claims about regulatory differences among endometrial carcinoma molecular classes must distinguish association, target-set robustness, and cross-cohort transportability. We evaluated a fetal Müllerian epithelial module and 20 prespecified developmental transcription-factor regulo...
