According to news originating from Lianyungang, People’s Republic o f China, by NewsRx editors, the research stated, “Robot technology shows broad a pplication prospects in rehabilitation medicine, especially in hand rehabilitati on. Hand function plays an important role that cannot be ignored in daily life, and its key properties are reflected in multiple levels.” The news editors obtained a quote from the research from Nanjing Medical Univers ity: “From basic life skills to occupational needs, healthy hand function is ind ispensable. Hand function is the foundation for performing daily life skills, in cluding activities such as self-care, eating, dressing, and grooming. The abilit y to freely use hand functions is directly related to an individual’s quality of life and independence. This study proposed a gesture recognition algorithm by f using Ycbcr color space and convolutional neural network. The method first conve rted gesture images and recognizes them through the converted images. Then, a ha nd function rehabilitation training robot based on Ycbcr and CNN was designed, w hich provided rehabilitation treatment for patients with impaired hand function. These experiments confirmed that when the data set size was 500, the signal-to- noise ratios of YOLOV3, YOLOV3-SPP, YOLOV4, and hybrid algorithms were 27.5dB, 3 2.7dB, 34.8dB, and 41.2dB, respectively.”

According to news reporting originating in Cambrid ge, Massachusetts, by NewsRx journalists, research stated, “Imitation learning ( IL) can train computationally-efficient sensorimotor policies from a resource-in tensive model predictive controller (MPC), but it often requires many samples, l eading to long training times or limited robustness. To address these issues, we combine IL with a variant of robust MPC that accounts for process and sensing u ncertainties, and we design a data augmentation (DA) strategy that enables effic ient learning of vision-based policies.” Financial support for this research came from MURI. The news reporters obtained a quote from the research from the Massachusetts Ins titute of Technology, “The proposed DA method, named Tube-NeRF, leverages Neural Radiance Fields (NeRFs) to generate novel synthetic images, and uses properties of the robust MPC (the tube) to select relevant views and to efficiently comput e the corresponding actions. We tailor our approach to the task of localization and trajectory tracking on a multirotor, by learning a visuomotor policy that ge nerates control actions using images from the onboard camera as only source of h orizontal position. Numerical evaluations show 80-fold increase in demonstration efficiency and a 50% reduction in training time over current IL m ethods.”

According to news reporting originating from O saka University by NewsRx correspondents, research stated, “Dynamic mode (DM) de composition decomposes spatiotemporal signals into basic oscillatory components (DMs).” Funders for this research include Mext | Japan Science And Technology Agency; Ja pan Agency For Medical Research And Development; Mext | Japan Society For The Pr omotion of Science. Our news correspondents obtained a quote from the research from Osaka University : “DMs can improve the accuracy of neural decoding when used with the nonlinear Grassmann kernel, compared to conventional power features. However, such kernel- based machine learning algorithms have three limitations: large computational ti me preventing real-time application, incompatibility with non-kernel algorithms, and low interpretability. Here, we propose a mapping function corresponding to the Grassmann kernel that explicitly transforms DMs into spatial DM (sDM) featur es, which can be used in any machine learning algorithm. Using electrocorticogra phic signals recorded during various movement and visual perception tasks, the s DM features were shown to improve the decoding accuracy and computational time c ompared to conventional methods. Furthermore, the components of the sDM features informative for decoding showed similar characteristics to the high-g power of the signals, but with higher trial-to-trial reproducibility.”

According to news reporting originating from Hart ford, Connecticut, by NewsRx editors, the research stated, “Artificial intellige nce has recently become available for widespread use in medicine, including the interpretation of digitized information, big data for tracking disease trends an d patterns, and clinical diagnosis. Comparative studies and expert opinion suppo rt the validity of imaging and data analysis, yet similar validation is lacking in clinical diagnosis.” Our news editors obtained a quote from the research from Hartford Hospital, “Art ificial intelligence programs are here compared with a diagnostic generator prog ram in clinical neurology. Using 4 nonrandomly selected case records from New En gland Journal of Medicine clinicopathologic conferences from 2017 to 2022, 2 art ificial intelligence programs (ChatGPT-4 and GLASS AI) were compared with a neur ological diagnostic generator program (NeurologicDx.com) for diagnostic capabili ty and accuracy and source authentication. Compared with NeurologicDx.com, the 2 AI programs showed results varying with order of key term entry and with repeat querying. The diagnostic generator yielded more differential diagnostic entitie s, with correct diagnoses in 4 of 4 test cases versus 0 of 4 for ChatGPT-4 and 1 of 4 for GLASS AI, respectively, and with authentication of diagnostic entities compared with the AI programs.”

According to news reporting originating from Vienna, Austria, by NewsRx correspondents, research stated, “The performance of postinstalled faste ners in concrete can be affected by the chosen drilling and setting techniques. In the context of the development of a drilling robot for construction site impl ementation the impact of an automated setting process on the pull-out loads of f astening systems was evaluated.” Financial support for this research came from Fischerwerke GmbH Co. Our news editors obtained a quote from the research from the University of Natur al Resources and Applied Life Science, “This article investigates the effect of two different fixing systems, drop-in expansion and chemical anchors, on the pul l-out behaviour of manual and robotic drilling and installation. While for chemi cal anchors, the results indicate that robotic installation leads to similar pul l-out forces with smaller deviation, expansion anchors in robotically drilled ho les show slightly lower pull-out loads than those in manually drilled holes. Fur thermore, a more uniform pull-out behaviour was observed for chemical anchors wh en set by the robot.”

According to news reporting out of Qingdao, People’s Republic of C hina, by NewsRx editors, research stated, “Complex risk factors make metro const ruction safety accidents prone to occur, and there are various types of accident s. Accident reports record detailed information about different types of acciden ts in text form.” Our news journalists obtained a quote from the research from the Qingdao Univers ity of Technology, “However, effectively utilizing such unstructured data presen ts a significant challenge. Text mining ™provides a viable foundation for addre ssing this challenge, but related studies have limitations in risk feature extra ction and lack of in-depth analysis capability. To address the deficiencies of e xisting studies and provide a feasible strategy for identifying key risk factors in the metro construction domain, this paper proposes an integrated model combi ning TM and machine learning-based Bayesian networks. Firstly, the term frequenc y-inverse document frequency (TF-IDF) algorithm in TM was used to separately ext ract the direct and indirect cause factors from the accident reports, with the m issing factors supplemented using the TextRank algorithm. Then, depending on the assumption of whether to consider the conditional independence between factors, an improved naive Bayesian network (NBN) and a tree-augmented naive Bayesian ne twork (TAN) were built based on the extracted factors and the corresponding acci dent types, respectively, for further in-depth analysis. Finally, the training s et was divided to train the two network models, and sensitivity analysis was use d to identify the key risk factors. Using 162 accident reports from China as an application example, the results showed that TAN exhibited a higher average accu racy (79.62 %) in the test set compared with the improved NBN (71.75 %), and the importance of risk factors for different accident types was successfully ranked from multiple perspectives using TAN. Meanwhile, some n ew insights into metro accidents in China were obtained, which can support decis ion-making for accident prevention and control.”
