This paper investigates the problem of global/semi-global finite-time consensus for integrator-type multi-agent sys-tems.New hyperbolic tangent function-based protocols are pro-posed to achieve global and semi-global finite-time consensus for both single-integrator and double-integrator multi-agent systems with leaderless undirected and leader-following directed commu-nication topologies.These new protocols not only provide an explicit upper-bound estimate for the settling time,but also have a user-prescribed bounded control level.In addition,compared to some existing results based on the saturation function,the pro-posed approach considerably simplifies the protocol design and the stability analysis.Illustrative examples and an application demonstrate the effectiveness of the proposed protocols. 展开更多

As all generators are distributed in different areas among large scale power systems,the cooperative manipulation of the multi-generator system cannot operate well without consideration of the distance information of the generators.A distributed step-by-step finite-time consensus scheme for the heterogeneous battery energy storage system(BESS)is proposed in this paper,where the coordinated consensus can come into reality within a limited time,which is appealing for the electrical engineering community.To be concrete,at first,all BESSs are classified into several clusters according to their locations,and in each cluster,there is an active leader in charge of information receiving from outside.Then,in order to coordinate the multi BESSs,five inputs,which are function oriented,were used to achieve energy level balancing,activeeactive power sharing,and the consensus of voltage and frequency of the multi BESSs.Furthermore,the frequency and voltage restoration to the nominal values of the main grid were made possible by the introduction of a virtual leader,which is actually an external leader.Compared with the centralized methods,this control scheme is entirely distributed,and each BESS only utilizes the information of its own and its neighbors.In addition,this control is robust to the load perturbation and the plug-and-play of the communication topology.Finally,some simulation experiments are executed on the modified IEEE 57-bus system to verify the suggested scheme. 展开更多

Background:Insufficient physical activity and prolonged sedentary behavior have emerged as major global public health challenges.Short bouts(≤10 min)of accumulated exercise(SBAE)throughout the day may be a promising strategy to mitigate the adverse effects of prolonged sitting and promote physical activity,ultimately promoting overall health.However,previous ambiguity in defining this concept has resulted in a fragmented and inconsistent evidence base,impeding practical applications,the development of guidelines,and policymaking.The purpose of this study is to establish an operational definition of SBAE by synthesizing systematic reviews and research trials alongside an expert consensus.Additionally,it seeks to evaluate acute and long-term efficacy and feasibility,providing evidence-based recommendations for practice and future research directions.Methods:A literature search was performed across PubMed and Web of Science,followed by systematic screening and summarization of eligible studies based on predefined inclusion criteria.Inclusion criteria encompassed various modesypes of SBAE(bouts lasting≤10 min,performed multiple times daily with≥30 min intervals);both aerobic and resistance exercise were considered.Relevant systematic reviews and research trials were included.Methodological quality,risk of bias,and evidence certainty were assessed.Expert consensus was obtained through a survey to evaluate recommendations and agreement levels on findings.Results:After analyzing 27 systematic reviews,135 research studies,and an expert consensus involving 48 researchers from 11 countries,SBAE is defined as any exercise mode of activity,regardless of intensity,that is accumulated in either continuous or intermittent bouts lasting≤10 min per session(including multiple intermittent sets)that are performed multiple times(≥2 sessions/day)per day,with intervals of≥30 min between bouts or otherwise sufficient time for recovery.When used to interrupt prolonged periods of sedentary time,SBAE mitigates the acute adverse effects of sedentary behavior on more than 10 clinical biomarkers of endocrine,cardiovascular,and brain health/function among adults of diverse ages and conditions.Moreover,SBAE was superior for improving acute glycemic control compared to a single continuous exercise session.As a long-term intervention(average of 11 weeks),SBAE can improve over 20 health outcomes,including peak oxygen uptake,resting blood pressure,and metabolic health.Additionally,SBAE might be more effective than continuous exercise for improving longer-term glycemic control and body composition.Long-term completion rates for SBAE interventions are generally high(95%),with low dropout rates(12%)and high adherence rates even without supervision(85%),and its safety has been preliminarily validated.Conclusion:An operational definition of SBAE is provided along with its classification and acute and long-term efficacy.Practical exercise prescription recommendations and evidence-based strategies for various populations and contexts are provided.Future research should focus on generating high-quality evidence for SBAE in 5 key areas:quantification and monitoring,population-specific responses,optimization of exercise prescriptions,intervention efficacy,and practical implementation.Additionally,addressing policy,environmental,and promotional barriers is crucial for transitioning from expert consensus to public consensus,and for facilitating the application of this strategy in real-world environments. 展开更多

With the advancement of surgical techniques and enhanced management of early gastric cancer(EGC),minimally invasive function-preserving surgical approaches have emerged as a common goal for patients and clinicians.Laparoscopic-endoscopic cooperative surgery combined with sentinel lymph node navigation surgery(LECSSNNS)has drawn increasing interest because of its dual benefits of minimal invasiveness and organ function preservation.However,robust evidence-based support for guiding clinical implementation remains limited.To address this gap,we systematically evaluated available studies on the clinical application of LECS-SNNS in EGC and integrated expert insights to formulate 20 recommendations.These included preoperative assessment,surgical techniques,intraoperative endoscopic procedures,pathological evaluation,postoperative care,and follow-up.This consensus aimed to provide comprehensive guidance for the standardized application of LECS-SNNS,thereby advancing precise,minimally invasive,and function-preserving treatment for EGC. 展开更多

OBJECTIVE:To develop an expert consensus on kidney deficiency syndrome(KDS)in pregnant women and construct a validated self-reported KDS Patient-Reported Measures Pregnancy Scale(KDS-PRMs-Pregnancy Scale)for early identification and management.METHODS:The study was conducted in three phases.First,a comprehensive review of Traditional Chinese Medicine(TCM)literature and diagnostic criteria was performed,generating initial KDS symptoms for pregnancy.Second,a two-round Delphi survey,involving 21 experts from TCM,obstetrics,and gynaecology,assessed importance,relevance,and appropriateness of the items.Third,a psychometric evaluation was conducted,including exploratory factor analysis and internal consistency assessment.RESULTS:In the first Delphi round,19 items were flagged for revision or removal due to expert variability,with 12 items deemed irrelevant.In the second round,consensus was reached,resulting in a 25-item scale.After psychometric evaluation,seven items were removed due to poor factor loadings,leaving an 18-item scale.Three factors—physiological discomfort,fatigue&weakness,and excretion abnormalities—accounted for 78.4%of the variance.The final scale demonstrated excellent internal consistency(Cronbach's alpha=0.959).CONCLUSION:The validated 18-item KDS-PRMsPregnancy Scale is a reliable tool for assessing KDS in pregnant women.Future research should focus on validation in diverse populations and exploring its predictive validity for pregnancy outcomes. 展开更多

Early colorectal cancer is often treated through endoscopic procedures to remove tumors.However,when initial removal is incomplete or shows high-risk features,further major surgery is required to ensure no cancer remains.This consensus provides a standard for surgeons to decide when and how to perform this additional surgery.A multidisciplinary group of Chinese medical experts reviewed global research and clinical evidence published between 2010 and 2024.The medical experts formulated key clinical recommendations,which were then discussed and finalized through expert voting to ensure high agreement.The consensus identifies specific high-risk factors necessitating additional surgery.The consensus recommends that these follow-up surgeries should ideally take place approximately 4 weeks after the first procedure.Furthermore,the consensus provides detailed protocols for marking the tumor location and selecting the best surgical approach.These consensuses offer a practical framework to improve the safety and effectiveness of treating early colorectal cancer.By standardizing surgical decisions,the consensus aims to help patients achieve better long-term recovery and quality of life. 展开更多

This paper studies the problem of privacy preservation in achieving the average consensus of dynamic Multi-Agent Systems(MAS).Average consensus performs an essential role in dynamic MAS to promote collaboration,coordinate decision-making,resolve conflicts,and enhance system reliability.The process of achieving average consensus requires the information exchange between agents,which raises concerns about sensitive data leakage.To address this issue,we propose a novel algorithm that combines state decomposition with edge characteristics in network topology to protect the critical data during the average consensus process.Specifically,the original state of each agent is decomposed into|Ni|+1 substates,where|Ni|represents the number of neighboring nodes.For each agent,the public substate performs the function of the original state to participate in computation and interaction between other agents,while the private parts only interact with the first one of the same agent and keep invisible to other agents.Unlike other approaches that focus solely on the privacy preservation of agents'initial state information,this paper extends to dynamic state of agents at every moment.Next,rigorous proofs of the accuracy in average consensus are provided.Furthermore,it is shown that privacy can be protected by employing our algorithm if agent i has at least one neighbor who is not an honest-but-curious agent.As for external eavesdroppers,a sufficient condition is presented that the state information is not estimated with any guaranteed accuracy.Finally,numerical simulations are presented to verify the effectiveness of our approach. 展开更多

First, we give out a nonlinear consensus protocol for the multi-species system with Brownian motion, and propose the definition of finite-time consensus in probability. Second, we prove that the multi-species system can achieve finite-time consensus in probability with different proper protocols by use of graph theory, stochastic Lyapunov function method and probability theory. Finally, some simulations are provided to illustrate the effectiveness of the theoretical results. 展开更多

In this paper,an analysis-definition-processing(ADP)framework is proposed to search positive-incentive noise in continuous action iterated dilemma(CAID).We analyze the influence of communication noise on the cooperative behavior of players in the system and introduce the concept of positive-incentive noise in CAID.We design a global cost function to ensure convergence of the system can be achieved and strive to improve the final level of cooperation.An optimal CAID control method is proposed to derive the deterministic optimal learning rate in analytical form,avoiding the variability and uncertainty brought about by neural network fitting or parameter adjustment.On this basis,the convergence of the dynamic model is further analyzed by using the Lyapunov function instead of the Jacobian matrix.Additionally,an adaptive filtering mechanism is designed to dynamically ensure that only positive-incentive noise affects the system,effectively reducing the impact of negative noise and enhancing system stability.The framework is validated through simulations involving triple classical game models,including the hawk-dove game,the stag hunt game,the chicken game on networks,and a straightforward illustrative example. 展开更多

The Internet of Vehicles(IoV)operates in highly dynamic and open network environments and faces serious challenges in secure and real-time authentication and consensus mechanisms.Existing methods often suffer from complex certificate management,inefficient consensus protocols,and poor resilience in high-frequency communication,resulting in high latency,poor scalability,and unstable network performance.To address these issues,this paper proposes a secure and efficient distributed authentication scheme for IoV with reputation-driven consensus and SM9.First,this paper proposes a decentralized authentication architecture that utilizes the certificate-free feature of SM9,enabling lightweight authentication and key negotiation,thereby reducing the complexity of key management.To ensure the traceability and global consistency of authentication data,this scheme also integrates blockchain technology,applying its inherent invariance.Then,this paper introduces a reputation-driven dynamic node grouping mechanism that transparently evaluates and groups’node behavior using smart contracts to enhance network stability.Furthermore,a new RBSFT(Reputation-Based SM9 Friendly-Tolerant)consensus mechanism is proposed for the first time to enhance consensus efficiency by optimizing the PBFT algorithm.RBSFT aims to write authentication information into the blockchain ledger to achieve multi-level optimization of trust management and decision-making efficiency,thereby significantly improving the responsiveness and robustness in high-frequency IoV scenarios.Experimental results show that it excels in authentication,communication efficiency,and computational cost control,making it a feasible solution for achieving IoV security and real-time performance. 展开更多

In this paper,the bounded control gain based prescribed-time(Pre-T)consensus problem for general linear multiagent systems(MASs)with controllable agent dynamics is addressed.First,an observer with Pre-T performance is designed for each agent to estimate the leader's state within a prescribed time.Then,based on the estimated states,a Pre-T switching controller integrating a bounded control gain is developed by employing a special coordinate transformation in combination with the backstepping technique,under the assumption that the agents'system matrix pair is controllable.It is shown that the proposed controller enables general linear MASs to achieve the Pre-T consensus independently of the agents'initial conditions and control parameters.Notably,the controller eliminates the numerical implementation problem associated with unbounded control gains,without compromising the consensus performance.The proposed approach is further applied to high-order singleinput MASs to demonstrate its broader applicability.Finally,a simulation example validates the effectiveness of both the proposed observer and the Pre-T switching controller. 展开更多

To address the finite-time tracking control problem for fractional-order nonlinear systems(FONSs) with actuator faults and external disturbance,a novel strategy of the finite-time adaptive fuzzy fault-tolerant controller is presented in this paper by utilizing the finite-time stability theory and fractional-order dynamic surface control scheme combined with backstepping method.A new lemma is developed for analyzing the finite-time stability of FONSs in terms of fractional differential inequality,which modifies some existing results.Fuzzy logic systems are adopted to identify unknown nonlinear characteristics in FONS.In order to compensate for the influence of unknown external disturbance and estimation error for fuzzy logic systems,an auxiliary function is employed to estimate the upper bound of parameters online.Furthermore,a global coordinate transformation is first introduced initially to decouple the fractional-order dynamic system of a specific class of underactuated single-link flexible manipulator systems,thereby transforming it into lower triangular systems.Simulation analyses and experimental results verify the feasibility and effectiveness of finite-time tracking control algorithm. 展开更多

In China,the incidence and mortality rates of hepatocellular carcinoma(commonly referred to as liver cancer)are relatively high.To further standardize the surgical treatment of liver cancer,the Liver Surgery Group of Chinese Society of Surgery took the lead in 2000 in formulating and releasing the selection of surgical treatment modalities for primary hepatocellular carcinoma,which was subsequently revised three times in 2004,2009,and 2016.In recent years,with the rapid advancement of medical science and technology,new concepts and treatment modalities have continuously emerged.Based on this,the Liver Surgery Group of Chinese Society of Surgery convened all committee members of the group,along with other leading domestic experts in liver surgery,to revise the fourth edition of the Expert Consensus on the Selection of Surgical Treatment Modalities for Hepatocellular Carcinoma,incorporating the latest advances in surgical treatment of liver cancer,ultimately resulting in the fifth edition of the Expert Consensus on the Selection of Surgical Treatment Modalities for Hepatocellular Carcinoma,intended for reference by physicians engaged in the diagnosis and treatment of liver cancer. 展开更多

Colorectal cancer(CRC)adjuvant therapy is evolving from tumor-node-metastasis stage-based strategies toward molecular-profiling-guided precision medicine.This minireview,based on a comprehensive literature search in PubMed and Web of Science using keywords related to CRC biomarkers and adjuvant therapy(from 2010 to 2025),examines how key biomarkers,including mismatch repair(MMR)status,rat sarcoma viral oncogene homologapidly accelerated fibrosarcoma mutations,consensus molecular subtypes,and circulating tumor DNA,refine risk stratification and treatment selection.Despite consensus guidelines advocating individualized therapy,significant disparities persist in real-world implementation due to technical variability in testing,limited or evolving evidence for specific scenarios(e.g.,adjuvant immunotherapy for MMR-deficient/microsatellite instability-high patients,wherein phase 3 trials such as ATOMIC have yet to report mature overall survival data),and health economic barriers.The mini-review analyzes gaps across testing,decision-making,and dynamic monitoring phases,and proposes integrated solutions involving technological innovation(e.g.,artificial intelligence-integrated multiomics,circulating tumor DNA monitoring),optimized clinical pathways,and supportive health policies.Bridging these gaps requires multidisciplinary collaboration to translate molecular insights into equitable,personalized adjuvant care for CRC patients. 展开更多
