According to news originating from Shanghai, People's Republic of China, by NewsRx correspondents, research stated, "This study introduces a new machine learning-based algorithm for the retrieving significant wave height (SWH) using synthetic aperture radar (SAR) images."Funders for this research include National Key Research And Development Program of China; National Natural Science Foundation of China; Natural Science Foundati on of Shanghai. The news reporters obtained a quote from the research from Shanghai Ocean Univer sity: "This algorithm is based on the azimuthal cut-off wavelength and was devel oped in quad-polarized stripmap (QPS) mode in coastal waters. The collected imag es are collocated with a wave simulation from the numeric model, called WAVEWATC H-III (WW3), and the current speed from the HYbrid Coordinate Ocean Model (HYCOM ). The sea surface wind is retrieved from the image at the vertical-vertical pol arization channel, using the geophysical model function (GMF) CSARMOD-GF. The re sults of the algorithm were validated against the measurements obtained from the Haiyang-2B (HY-2B) scatterometer, yielding a root mean squared error (RMSE) of 1.99 m/s with a 0.82 correlation (COR) and 0.27 scatter index of wind speed. It was found that the SWH depends on the wind speed and azimuthal cut-off wavelengt h. However, the current speed has less of an influence on azimuthal cut-off wave length."

According to news reporting from Changchun, People's Repu blic of China, by NewsRx journalists, research stated, "Cr(VI) and phenol common ly coexist in wastewater, posing a great threat to the environment and human hea lth. However, it is still a challenge for microorganisms to degrade phenol under high Cr(VI) stress."Funders for this research include National Natural Science Foundation of China, Education Department of Jilin Province of China. The news correspondents obtained a quote from the research from Jilin Agricultur al University, "In this study, the phenol-degrading strain ZWB3 was co-cultured with the Cr(VI)-reducing strain MZ-1 to enhance phenol biodegradation under Cr(V I) stress. Compared with phenol-degrading strain ZWB3, which has weak tolerance to Cr(VI), and Cr(VI)-reducing strain MZ-1, which has no phenol-degrading abilit y, the co-culture of two strains could significantly increase the degraded rate and capacity of phenol. In addition, the co-cultured strains exhibited phenol de gradation ability over a wide pH range (7-10). The reduced content of intracellu lar proteins and polysaccharides produced by the co-cultured strains contributed to the enhancement of phenol degradation and Cr(VI) tolerance. The determinatio n coefficients , RMSE, and MAPE showed that the BP-ANN model could predict the d egradation of phenol under various conditions, which saved time and economic cos t. The metabolic pathway of microbial degradation of phenol was deduced by metab olic analysis."

    Beijing Institute of Technology Researchers Report Research in Virtual Reality a nd Intelligent Hardware (Effects of virtual agents on interaction efficiency and environmental immersion in MR environments)

According to news originating from Beijing, P eople's Republic of China, by NewsRx correspondents, research stated, "Physical entity interactions in mixed reality (MR) environments aim to harness human capa bilities in manipulating physical objects, thereby enhancing virtual environment (VEs) functionality. In MR, a common strategy is to use virtual agents as subst itutes for physical entities, balancing interaction efficiency with environmenta l immersion."Our news journalists obtained a quote from the research from Beijing Institute o f Technology: "However, the impact of virtual agent size and form on interaction performance remains unclear. Two experiments were conducted to explore how virt ual agent size and form affect interaction performance, immersion, and preferenc e in MR environments. The first experiment assessed five virtual agent sizes (25 %, 50%, 75%, 100%, and 125% of physical size). The second experiment tested four types of frames (no frame, consistent frame, half frame, and surrounding frame) across all agent sizes. Par ticipants, utilizing a head-mounted display, performed tasks involving moving cu ps, typing words, and using a mouse. They completed questionnaires assessing asp ects such as the virtual environment effects, interaction effects, collision con cerns, and preferences. Results from the first experiment revealed that agents m atching physical object size produced the best overall performance. The second e xperiment demonstrated that consistent framing notably enhances interaction accu racy and speed but reduces immersion. To balance efficiency and immersion, frame less agents matching physical object sizes were deemed optimal."

Acc ording to news originating from Beijing, People's Republic of China, by NewsRx c orrespondents, research stated, "Metabolic syndrome (MetS) is considered to be a n important parameter of cardio-metabolic health and contributing to the develop ment of atherosclerosis, type 2 diabetes. The incidence of MetS significantly in creases in postmenopausal women, therefore, the perimenopausal period is conside red a critical phase for prevention."Our news journalists obtained a quote from the research from Peking University, "We aimed to use four machine learning methods to predict whether perimenopausal women will develop MetS within 2 years. Women aged 45-55 years who underwent 2 consecutive years of physical examinations in Ninth Clinical College of Peking U niversity between January 2021 and December 2022 were included. We extracted 26 features from physical examinations, and used backward selection method to selec t top 10 features with the largest area under the receiver operating characteris tic curve (AUC). Extreme gradient boosting (XGBoost), Random forest (RF), Multil ayer perceptron (MLP) and Logistic regression (LR) were used to establish the mo del. Those performance were measured by AUC, accuracy, precision, recall and F1 score. SHapley Additive exPlanation (SHAP) value was used to identify risk facto rs affecting perimenopausal MetS. A total of 8700 women had physical examination records, and 2,254 women finally met the inclusion criteria. For predicting Met S events, RF and XGBoost had the highest AUC (0.96, 0.95, respectively). XGBoost has the highest F1 value (F1 = 0.77), followed by RF, LR and MLP. SHAP value su ggested that the top 5 variables affecting MetS in this study were Waist circumf erence, Fasting blood glucose, Highdensity lipoprotein cholesterol, Triglycerid es and Diastolic blood pressure, respectively. We've developed a targeted MetS r isk prediction model for perimenopausal women, using health examination data."

    Research from Saint Martin's University Provide New Insights into Robotics (New Design and Prototype of Two Degrees-of-Freedom Planar Parallel Manipulator for U se in Creating an Infinite 3D Printer)

    36-36页
    查看更多>>摘要:By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Current study results on robotics have been published. According to news reporting originating from Saint Martin's Uni versity by NewsRx correspondents, research stated, "This paper presents a novel two degrees-of-freedom planar parallel manipulator (PPM) designed for infinite-a xis 3D printing, alongside tools for facilitating future design iterations."The news editors obtained a quote from the research from Saint Martin's Universi ty: "Unlike traditional gantry-supported designs used in infinite-axis 3D printi ng, which impose significant mass movement requirements, the examined new design prioritizes reducing overall weight to enhance speed potential at the cost of a reduced work area. In this innovative approach, the PPM effectively reduces wei ght by decoupling the motion of the hot end from that of the motor. Motors are a ttached to the frame, controlling a system of pulleys, and connecting arms to dr ive the hot-end's motion. Due to the length of the arms, the hot end will be una ble to fully explore the entire printing plane. Verification of the angled PPM f or 3D printing involved developing kinematic and dynamic equations, conducting f inite element analysis on critical components, and testing a completed prototype . A metaheuristic optimization method was employed to derive optimal design para meters, focusing on optimizing the arm length of the connectors while maximizing dynamic performance."
