An AI‐enabled micromixing framework is developed by integrating cGAN with Bayesian optimization for predictive control of microrobot‐driven flow manipulation. Through this framework, the spatiotemporal evolution of micromixing is learned directly from experimental images, while rapid identification of optimized microrobot actuation strategies is ...

ABSTRACT Background Robotic computer‐assisted implant surgery (r‐CAIS) aims to improve implant placement trueness, but existing reviews include heterogeneous designs, and no review has exclusively synthesized RCTs to date. This review aimed to evaluate the positional trueness and clinical outcomes of r‐CAIS compared with free‐hand implant surgery (FHIS)

First‐principles investigation of A2CaTiH6 (A = Li, Na, K, Rb) hydrides reveals structural, electronic, mechanical, thermodynamic, and hydrogen storage properties. Negative formation energies confirm stability, while all compounds are metallic and mechanically stable. K2CaTiH6 and Rb2CaTiH6 are dynamically stable, with capacities of 2.28 wt.%–5.61 wt.%.

This study addresses hard roof coal seam conditions by optimizing key stratum blasting‐cutting parameters through theoretical analysis, numerical simulation, and field tests. It proposes calculation methods for blast hole spacing and delay timing based on stress wave theory, controlling roadway deformation within 35 mm, thereby enhancing resource ...

Prediction of Directional Changes in Well Drilling Based on Formation Rock Strength
To increase oil and gas production deviated wells are drilled where the wellpath changes both in the horizontal and vertical planes. Directional change tolerances are becoming tighter because wells have to be placed with increased accuracy in soft ...

This study investigates three methodologies for measuring boulder axes in coastal boulder ridge deposits. Traditional Tape Measurements were statistically compared against handheld LiDAR data and digitised boulder perimeters from a UAV generated orthomosaic collected at the Grind o' da Navir, Shetland.
