According to news reporting from Beijing, People’s Republic of China, by NewsRx journalists, research stated, “In this article, the dynamics of a seve n degrees of freedom robot with a telescopic forearm for the spray-painting of l arge workpiece is investigated.” The news reporters obtained a quote from the research from Tsinghua University: “A novel two-step inverse kinematic solving method that combines numerical and a nalytical approaches is proposed to solve the inverse kinematics of the seven de grees of freedom robot with two redundant degrees of freedom for spray-painting applications. Based on the kinematic model, the dynamic model is derived using t he Newton-Euler method. For the dynamic parameter identification, the dynamic mo del is written in a linear form with respect to dynamic parameters. Considering the effect of the telescopic forearm on the dynamics of the robot, two novel per formance indices concerning the inertial load and gravitational load in the join t space are proposed to evaluate the effect of the telescopic forearm on the dyn amic load of the robot.”

According to news reporting originating from College Station, Te xas, by NewsRx correspondents, research stated, “Pluvial flash floods are fast-m oving hazards and causes significant disruptions in urban areas. With the increa se in heavy precipitations, the ability to proactively identify flash floods hot spots in cities is critical for flood nowcasting and predictive monitoring of ri sks.” Financial support for this research came from National Science Foundation (NSF). Our news editors obtained a quote from the research from Texas A&M University, “While rainfall runoff models and hydrologic models are useful model s for flash flood prediction, these models are computationally expensive and eff ort intensive to be used for flood nowcasting. To address this challenge, this s tudy presents interpretable machine learning models for predicting urban flash f lood hotspots based on intertwined land and built environment features. The task of predicting flash flood hotspots is formulated as a binary classification pro blem, and three recent flash flood events in U.S. cities are selected for data c ollection and model validation. Various features related to land and built envir onment characteristics are constructed using diverse datasets, and the occurrenc es of flash floods are captured using crowdsource data from the events. Using th ese features and datasets, the flash flood hotspots of cities are predicted with two ensemble models based on decision trees. The results demonstrate that the m odels can achieve good accuracy (0.8) in identifying flooded/non-flooded locatio ns. Especially, the models can achieve high true positive rate (0.83-0.89) and l ow missing rate, demonstrating the methods’ practicability for accurately predic ting flooded hotspots. The model interpretation results indicate that land featu res related to hydrological and topological features have greater impacts on fla sh flood risk, than built environment features. Further analysis reveals that th e feature importance, model performance, and model transferability performance v ary among cities and localized specifications of the models are needed for accur ate prediction of flash flood for a particular city.”

According to news reporting out of Buffalo, New York, by NewsRx editors, research stated, “Artificial intelligence models represented in machine learning algorithms are promising tools for risk assessment used to guid e clinical and other health care decisions.” Funders for this research include Nih Nlm. Our news editors obtained a quote from the research from State University of New York (SUNY) Buffalo: “Machine learning algorithms, however, may house biases th at propagate stereotypes, inequities, and discrimination that contribute to soci oeconomic health care disparities. The biases include those related to some soci odemographic characteristics such as race, ethnicity, gender, age, insurance, an d socioeconomic status from the use of erroneous electronic health record data. Additionally, there is concern that training data and algorithmic biases in larg e language models pose potential drawbacks. These biases affect the lives and li velihoods of a significant percentage of the population in the United States and globally. The social and economic consequences of the associated backlash canno t be underestimated.”

According to news reporting from Vienna, Austria, by NewsRx journ alists, research stated, “Sensory feedback for prosthesis control is typically b ased on encoding sensory information in specific types of sensory stimuli that t he users interpret to adjust the control of the prosthesis. However, in physiolo gical conditions, the afferent feedback received from peripheral nerves is not o nly processed consciously but also modulates spinal reflex loops that contribute to the neural information driving muscles.” The news correspondents obtained a quote from the research from the Medical Univ ersity of Vienna, “Spinal pathways are relevant for sensory-motor integration, b ut they are commonly not leveraged for prosthesis control. We propose an approac h to improve sensory-motor integration for prosthesis control based on modulatin g the excitability of spinal circuits through the vibration of tendons in a clos ed loop with muscle activity. We measured muscle signals in healthy participants and amputees during different motor tasks, and we closed the loop by applying v ibration on tendons connected to the muscles, which modulated the excitability o f motor neurons. The control signals to the prosthesis were thus the combination of voluntary control and additional spinal reflex inputs induced by tendon vibr ation. Results showed that closed-loop tendon vibration was able to modulate the neural drive to the muscles. When closed-loop tendon vibration was used, partic ipants could achieve similar or better control performance in interfaces using m uscle activation than without stimulation. Stimulation could even improve prosth etic grasping in amputees.”
