According to news reporting out of Beijing, People's Republic of China, by NewsRx editors, research stated, "Calculation of the stress intensity factor K is a crucial and difficult task in linear elastic fracture mechanics. With the capacity to solve complex input-output problems of an underlying system, machine learning is especially useful in the calculation of K. However, when faced with complex systems, such as the firtree groove structure of a turbine disk, the data-consuming issue has always been a thorny problem in K -solutions combined with machine learning studies for a long time." Funders for this research include National Major Science and Technology Project, Fundamental Research Funds for the Central Universities. Our news journalists obtained a quote from the research from Beihang University, "In this paper, a novel K -solution method called PA-GPR (Pool -based Active learning with Gaussian Process Regression) for the calculation of the stress intensity factor for surface cracks in the firtree groove structure of a turbine disk is proposed. Using the pool -based active learning strategy, the proposed K -solution method could make the GPR model have a great regression performance with a few samples required. In the pool -based active learning strategy analysis, the learning function based on greedy sampling is proposed to select samples with a high contribution to the training of the GPR model. The calculation of K for a semi -elliptical surface crack in the firtree groove structure is evaluated to verify the accuracy and effectiveness of the proposed method."

    New Machine Learning Study Findings Reported from University of Colombo (webdraw: a Machine Learning-driven Tool for Automatic Website Prototyping)

According to news reporting from Colombo, Sri Lanka, by NewsRx journalists, research stated, "To overcome the time-consuming nature and improve the cost-effectiveness of classical web development, being automatic is the most convenient alternative recent researchers suggest. Over the years, researchers have been working on inventing new approaches to generating websites automatically." The news correspondents obtained a quote from the research from the University of Colombo, "In this paper, a novel approach is presented that automates the website generation process by incorporating web designer best practices and driving new prototype websites without the significant effort of redesigning websites. It takes high-fidelity mock-up design artifacts such as screen captures of real-world websites, and generates functional websites similar to the input websites, which involves three steps: GUI element detection, classification, and code generation. First, image processing techniques are applied to detect atomic web GUI elements from a mock-up design artifact of a real-world website. Second, a Convolutional Neural Network (CNN) is trained to classify the extracted web GUI elements into their domain-specific types such as headings, paragraphs, images, etc. A Graphical User Interface (GUI) is typically represented in code as a hierarchical tree, with nested GUI elements bundled together within one another to construct a tree. A recursive algorithm is proposed that constructs the appropriate Document Object Model (DOM) hierarchy for a website by recursively grouping classified web GUI elements within each other. Finally, the constructed DOM is converted to the accurate native code. The approach was implemented as a tool called WebDraw. Design science research evaluation shows that WebDraw achieves an average of 90% web GUI element classification and generates website prototypes that are visually similar to the target website design mock-up artifact while producing functional GUI code."

The news reporters obtained a quote from the research from King's College Hospital, "We assess the ability of large language models (LLMs) within the context of radiology specialty exams to determine whether they can evaluate relevant clinical information. A database of questions was created with official sample, author written, and textbook questions based on the Royal College of Radiology (United Kingdom) FRCR 2A and American Board of Radiology (ABR) Certifying examinations. The questions were input into the Generative Pretrained Transformer (GPT) versions 3 and 4, with prompting to answer the questions. One thousand seventy-two questions were evaluated by GPT-3 and GPT-4. 495 (46.2%) were for the FRCR 2A and 577 (53.8%) were for the ABR exam. There were 890 single best answers (SBA), and 182 true/false questions. GPT-4 was correct in 629/890 (70.7%) SBA and 151/182 (83.0%) true/false questions. There was no degradation on author written questions. GPT-4 performed significantly better than GPT-3 which selected the correct answer in 282/890 (31.7%) SBA and 111/182 (61.0%) true/false questions. Performance of GPT-4 was similar across both examinations for all categories of question. The newest generation of LLMs, GPT-4, demonstrates high capability in answering radiology exam questions. It shows marked improvement from GPT-3, suggesting further improvements in accuracy are possible."

According to news reporting originating in Shanghai, People's Republic of China, by NewsRx journalists, research stated, "Electrochemical CO2 reduction reaction (CO2RR) has become a promising application in addressing energy challenges and environmental crises. However, the scaling relationship between the reaction intermediates constrains the successful deep reduction of CO2." Funders for this research include National Natural Science Foundation of China (NSFC), National Key Research and Development Project, Fundamental Research Funds for the Central Universities. The news reporters obtained a quote from the research from Tongji University, "Dual-metal-site catalysts (DMSCs) have emerged as potential electrocatalysts for CO2RR by breaking the scaling relationship due to their more adaptable active sites. Herein, this study aims to investigate the correlation between the adsorption energies of essential intermediates in CO2RR catalysis with double transition metal atoms anchored on graphdiyne monolayer (TM1-TM2@GDY) through machine-learning (ML) assisted density functional theory (DFT) calculations. The results reveal the important descriptors of CO2RR catalyzed by TM1-TM2@GDY, and demonstrate that the heteronuclear TM1TM2@GDY have great potential for deep CO2 reduction. Especially, Co-Mo@GDY and Co-W@GDY show low limiting potential (-0.60 V and -0.39 V, respectively) and high selectivity on the reaction from CO2 to CH4 based on the free energy diagrams. This study indicates that the two TM atoms on GDY act cooperatively for the catalysis of CO2RR."
