According to news reporting originating in London, United Kingdom, by NewsRx journalists, research stated, "Bowel endometriosis impacts quality of life. Treatment requires complex surgical procedures with associated morbidity." The news reporters obtained a quote from the research from Princess Grace Hospital, "Precision approach with robotic surgery leads to organ preservation. Bowel endometriosis requires a multidisciplinary management to improve patient outcomes. This study evaluates perioperative outcomes of bowel endometriosis undergoing multidisciplinary planning and robotic surgery. Consecutive cases of multidisciplinary robotic bowel endometriosis procedures (January 2021-December 2022) were evaluated from a prospectively maintained database in a national endometriosis accredited centre. Patients were managed through a multidisciplinary setting including gynaecologists, colorectal robotic surgeons, and other specialists. Dyschezia (menstrual and non-cyclical) and quality of life were assessed pre- and postoperatively (6 months) through validated questionnaires. Sixty-eight consecutive cases of robotic bowel endometriosis were included. Median age was 35.0 (30.2-42.0) years. Median body mass index was 24.0 (21.0-26.7) kg/m. Procedures performed were 48 (70.6%) shavings, 11 (16.2%) deep shavings, 3 (4.4%) disc excisions, and 6 (8.8%) segmental resections. One (1.5%) patient required temporary stoma. Median operating time was 150 (120-180) min. There were no conversions/return to theatre postoperatively. Median endometriotic nodule size was 25.0 (15.5-40.0) mm. Two (2.9%) patients developed postoperative complications. Median length of postoperative stay was 2 (2-4) days. Median follow-up was 12 (7-17) months. One (1.5%) patient recurred. Median menstrual dyschezia score improved from 5.0 (2.0-8.0) to 1.0 (0.0-5.7). Median non-cyclical dyschezia significantly improved (p ＜0.001) from 1.0 (0.0-5.7) to 0.0 (0.0-2.0). Median quality of life score improved from 52.5 (35.0-70.0) to 74.5 (60.0-80.0)."

According to news reporting originating from Sao Carlos, Brazil, by NewsRx correspondents, research stated, "Conveyor belts are the most effective way to transport ore in a mining complex. The ore that comes from the mining areas can be heterogeneous in size and type." Our news editors obtained a quote from the research from the University of Sao Paulo, "As the ore has to pass through several processing stages, online information about the ore type and degree of fragmentation can help improve mineral processing for both safety and efficiency. Current instrumentation systems are expensive and require frequent calibration and maintenance. This article presents a novel intelligent instrument for online recognition of type and degree of fragmentation. A 2-D light detection and ranging (LiDAR) sensor along with machine learning (ML) techniques was used to estimate the characteristics of iron ore particles on conveyor belts. An experiment was conducted using several types of ore and granulometry. Five ML models were compared by means of statistical methods, including average accuracy and normality and hypothesis tests. Among them, the random forest (RF) models achieved the highest rate of accuracy, 93.81% for ore type and 85.52% for degree of fragmentation. These models were improved by a voting mechanism that resulted in a reduction of classification errors of 93.3% for ore type and 99.2% for degree of fragmentation."

According to news reporting out of Chongqing, People's Republic of China, by NewsRx editors, research stated, "This paper delves into the practical application of K-Nearest Neighbors (KNN), Kernel Ridge Regression (KRR), and Lasso Regression for the prediction of viscosity of ionic liquids in a dataset characterized by categorical variables (Cation, Anion) and numeric variables (T(K), xIL(mol%))." The news journalists obtained a quote from the research from Chongqing Chemical Industry Vocational College: "Indeed, mole percentage of ionic liquids and temperature were considered as inputs for the models. The models' effectiveness is rigorously assessed, with K-Nearest Neighbors notably exhibiting exceptional predictive performance. To enhance model accuracy, Tabu Search is employed as an optimization tool for hyperparameter tuning. Numeric results showcase KNN's superiority, supported by a remarkable R2 test score of 0.91628 and the lowest RMSE among the models. Tabu Search optimization further refines model performance, emphasizing the critical role of hyperparameter tuning in achieving robust regression models in predicting the viscosity of ionic liquid-water mixtures."

According to news reporting originating from Bristol, United Kingdom, by NewsRx correspondents, research stated, "This paper presents a weakly supervised machine learning method, which we call DAS-N2N, for suppressing strong random noise in distributed acoustic sensing (DAS) recordings. DAS-N2N requires no manually produced labels (i.e. pre-determined examples of clean event signals or sections of noise) for training and aims to map random noise processes to a chosen summary statistic, such as the distribution mean, median or mode, whilst retaining the true underlying signal."

According to news reporting originating in Harbin, People's Republic of China, by NewsRx journalists, research stated, "Water jumping motion extends the robot's movement space and flexibility. However, the jumping performance is influenced by multiple factors such as driving force, rowing trajectory, and robot structure." Financial support for this research came from Equipment Pre-Research Application Innovation Project. The news reporters obtained a quote from the research from the Harbin Institute of Technology, "The interaction force between the robot and water surface is complicated due to water deformation, and the difficulty of the water jumping increases with the robot's scale. This article designs a miniature water jumping robot with rowing driving legs. The hydrodynamic model between driving legs and water is established based on the modified Wagner theory with consideration of water surface deformation. Particularly, the dynamic model of the robot for the whole jumping process is also developed related to multiple factors. Then, the jumping performance is improved by optimizing the energy storage modality, rowing trajectory, and supporting leg shapes through the theoretical analysis and experiments. The fabricated robot weights 91 g, and its length, width, and height are 220, 410, and 95 mm, respectively."
