According to news reportingout of Singapore, Singapore, by New sRx editors, research stated, "Nowadays, humans are allowed to workside-by-side with a robot team, which consists of dual robots in most cases. To ensure human safety, themotion of each robot should be reactive to and compliant with human s via human-in-the-loop control."Financial support for this research came from National Research Foundation, Sing apore, under theNRF Medium Sized Centre scheme (CARTIN).Our news journalists obtained a quote from the research from Nanyang Technologic al University,"Furthermore, when the robots conduct a cooperative task, the rea ctive and compliant motion of eachrobot must fulfill the constraints imposed by the cooperation with the other robot. It is challenging toguarantee human safe ty and robot cooperation simultaneously, especially in a decentralized architecture. This letter presents a decentralized control framework that guarantees both human safety and robotcooperation in human dual-robot interaction. First, the high-order time-varying control barrier functions(HO-TV-CBFs) are defined to re present human safety, based on which a safety control set is formulatedto guara ntee human safety. Second, the cooperation functions are introduced to abstract the cooperationconstraints of different cooperative tasks of dual robots, which are further guaranteed by a cooperationcontrol set. Then, a centralized contro l framework based on the safety and cooperation control setsis constructed. Fin ally, the centralized control framework is decentralized while maintaining the s ameperformance."

According to newsreporting originating in Krishnankoil , India, by NewsRx journalists, research stated, "Software-definednetwork (SDN) platforms play a key role in providing security against today's Internet attack s. SDNsdecouple the control plane from the data plane to maximize network perfo rmance."The news reporters obtained a quote from the research from the Kalasalingam Acad emy of Researchand Education, "A DDOS attack is one of several in cloud-based n etworks. SDNs play a crucial role incontrolling DDoS attacks and protecting end nodes like IoT nodes, as well as other computing devices,in large-scale cloud networks. This paper provides an efficient approach to DDoS attack detection andprevention using machine learning algorithms. The paper analyses the performanc e of SDNs in IoTsystems, incorporating a huge set of computing devices that use multi-controllers. It also proposes aneffective method to handle DDoS attacks. DDoS attacks are generated from IoT end devices in theinfrastructure layer, wh ich targets resources via an SDN-controlled testbed. The proposed ML methodoutp erforms existing methods in terms of accurately and effectively detecting and mi tigating floodingDDoS attacks with 99.99% accuracy."

According to news reportingoriginating from Gauhati, India, by NewsRx correspondents, research stated, "In this article, the snake robothavin g nine links with eight joints is considered for serpentine motion in the underw ater environment.The movement of a snake robot occurs due to nonlinear drag for ces and fluidic torque in underwaterconditions."Funders for this research include IITG Technology Innovation and Development Fou ndation (IITGTIDF), Department of Science & Technology (India).Our news editors obtained a quote from the research from Indian Institute for Te chnology, "Theuncertainties in drag forces and fluidic torque are considered to track the head angle and tangentialvelocity in this work. The virtual holonomi c constraints are formulated to track all the joints by designinga controller f or single joint. The parameters of gait pattern are obtained using the sliding s urface. Thesliding surface is formulated for head link angle and velocity track ing. Super twisting sliding mode controlapproach is proposed to deal with uncer tainties, and results are compared with sliding mode control andadaptive slidin g mode control. The robustness of controller is verified by inputting measuremen t noise.The significant improvement has been observed in chattering indicator a nd control effort by using theproposed super twisting sliding mode control."

According tonews reporting out of Katowice, Polan d, by NewsRx editors, research stated, "This study evaluatesthe effectiveness o f the ChatGPT-3.5 language model in providing correct answers to pathomorphologyquestions as required by the State Speciality Examination (PES). Artificial int elligence (AI) in medicine isgenerating increasing interest, but its potential needs thorough evaluation."Our news journalists obtained a quote from the research from the Medical Univers ity of Silesia,"A set of 119 exam questions by type and subtype were used, whic h were posed to the ChatGPT-3.5 model. Performance was analysed with regard to t he success rate in different question categoriesand subtypes. ChatGPT-3.5 achie ved a performance of 45.38%, which is significantly below the minimum PES pass threshold. The results achieved varied by question type and subtype, with better resultsin questions requiring ‘comprehension and critical thinking ' than ‘memory'. The analysis shows that,although ChatGPT-3.5 can be a useful t eaching tool, its performance in providing correct answers topathomorphology qu estions is significantly lower than that of human respondents. This conclusion highlights the need to further improve the AI model, taking into account the spec ificities of the medicalfield."
