Abstract Objectives We aim to build a generalizable information extraction system leveraging large language models extract granular eligibility criteria for diverse diseases from free text clinical trial protocol documents. investigate the model’s capability entities along with contextual attributes including values, temporality, and modifiers present strengths limitations of this system. Materials Methods The data were acquired https://ClinicalTrials.gov/. developed system, AutoCriteria,...
Grinding is a highly precise machining process. However, excessive temperatures during grinding can result in adverse thermal effects on the machined material. In this study, cup wheel was analyzed using model that represents heat generation as trochoid discrete source formed by interactions between abrasive particles and workpiece surface. With approach, certain assumptions were made to facilitate analysis, including modeling of grains rigid point sources. Finite element simulations...
Abstract High-frequency electric pulse signals are often applied to stimulate functional materials in devices. To investigate the relationship between structure and dynamic behavior under high-frequency excitation, stroboscopic imaging mode is widely used a transmission electron microscope (TEM). From technical point of view, it crucial quantitatively determine attenuation an electric-pulse-excited TEM. Here, we propose quantitative method evaluate voltage by using magnification variation...
Polyether-ether-ketone (PEEK) and polyimide (PI) are two kinds of engineering polymer materials widely used as roller bearing cages rings under extreme environment because their noise reduction corrosion resistance properties. The Si3N4 ceramic is the most common ball material. Many current applications bearings require aqueous lubrication. Therefore, this study presents lubrication tribopairs formed by PEEK PI material sliding against ceramic. Experimental results show that exhibited...
Superlubricity has been recognized as the future of tribology. However, it is hard to achieve superlubricity under extreme conditions such a high load and low sliding speed on macroscale. In this paper, remarkable synergetic lubricating effect between nanoparticles silicon nitride (Si3N4) demonstrated; helps water-lubricated Si3N4 successfully. Different kinds hairy silica were prepared, dispersed into water, characterized using variety methods. The tribological properties with nanoparticle...
(1) Background: Diabetic retinopathy, one of the most serious complications diabetes, is primary cause blindness in developed countries. Therefore, prediction diabetic retinopathy has a positive impact on its early detection and treatment. The based high-dimensional small-sample-structured datasets (such as biochemical data physical data) was problem to be solved this study. (2) Methods: This study proposed XGB-Stacking model with foundation XGBoost stacking. First, wrapped feature selection...
Vibration-assisted grinding is one of the most promising technologies for manufacturing optical components due to its efficiency and quality advantages. However, damage crack propagation mechanisms materials in vibration-assisted are not well understood. In order elucidate mechanism abrasive scratching during grinding, a kinematic model vibration was developed. The influence process parameters on evolution scratches indentation or straight revealed by displacement metrics velocity metrics....
Abstract The remarkable advances in ultra-precision machining technology have forced a re-examination of the effect spindle perpendicularity errors on milled surface quality at micro-nano scale. In this paper, method precision adjustment is proposed to improve finish quality. sensitive process are identified based multi-body kinematic theory by taking milling as an example. A 2-DOF rotation platform designed, optimized, and fabricated. static model established elastic beam verified finite...
