| 1 | Municipal wastewater treatment in China:Development history and future perspectives显示文摘China has the world's largest and still growing wastewater sector and water market,thus its future development will have profound influence on the world.The high-speed development of China's wastewater sector over the past 40 years has forged its global leading treatment capacity and innovation ability.However,many problems were left behind,including underdeveloped sewers and sludge disposal facilities,low sustainability of the treatment processes,questionable wastewater treatment plant(WWTP)effluent discharge standards,and lacking global thinking on harmonious development between wastewater management,human society and the nature.Addressing these challenges calls for fundamental changes in target design,policy and technologies.In this mini-review,we revisit the development history of China's municipal wastewater management and identify the remaining challenges.Also,we highlight the future needs of sustainable development and exploring China's own wastewater management path,and outlook the future from several aspects including targets of wastewater management,policies and technologies,especially the new concept WWTP.Furthermore,we envisage the establishment of new-generation WWTPs with the vision of turning WWTP from a site of pollutant removal into a plant of energy,water and fertilizer recovery and an integrated part urban ecology in China. | Jiuhui Qu Hongchen Wang Kaijun Wang Gang Yu Bing Ke Han-Qing Yu Hongqiang Ren Xingcan Zheng Ji Li Wen-Wei Li Song Gao Hui Gong | 2019 | Frontiers of Environmental Science & Engineering2019，13，6： | 13 |
| 2 | Epidermal self-powered sweat sensors for glucose and lactate monitoring显示文摘Sweat could be a carrier of informative biomarkers for health status identification;therefore,wearable sweat sensors have attracted significant attention for research.An external power source is an important component of wearable sensors,however,the current power supplies,i.e.,batteries,limit further shrinking down the size of these devices and thus limit their application areas and scenarios.Herein,we report a stretchable self-powered biosensor with epidermal electronic format that enables the in situ detec-tion of lactate and glucose concentration in sweat.Enzymatic biofuel cells serve as self-powered sensing modules allowing the sweat sensor to exhibit a determination coefficient(R2)of 0.98 with a sensitivity of 2.48 mV/mM for lactate detection,and R2 of 0.96 with a sensitivity of 0.11 mV/μM for glucose detection.The microfluidic channels developed in an ultra-thin soft flexible polydimethylsiloxane layer not only enable the effective collection of sweat,but also provide excellent mechanical properties with stable performance output even under 30%stretching.The presented soft sweat sensors can be integrated at nearly any location of the body for the continuous monitoring of lactate and glucose changes during normal daily activities such as exercise.Our results provide a promising approach to develop next-generation sweat sensors for real-time and in situ sweat analysis. | Xingcan Huang Jiyu Li Yiming Liu Tszhung Wong Jingyou Su Kuanming Yao Jingkun Zhou Ya Huang Hu Li Dengfeng Li Mengge Wu Enming Song Shijiao Han Xinge Yu | 2022 | Bio-Design and Manufacturing2022，5，1： | 3 |

| 5 | Soft,stretchable,wireless intelligent three-lead electrocardiograph monitors with feedback functions for warning of potential heart attack显示文摘Cardiovascular diseases(CVDs)are fatal chronic diseases,where electrocardiography(ECG)monitoring could be a prominent solution for early diagnosis.In spite of available commercialized,multilead ECG devices,bulky formats,discontinuous monitoring,and no safety alarm system significantly limit their practical applications.Herein,we present a soft,and stretchable,three-lead ECG device allowing continuous monitoring and wireless transmission of ECG signals.A newly developed organohydrogel patch with a strong adhesive ability(~9.9 kPa)and higher conductivity(~6.5 kΩ)is applied for high-quality ECG signals collection.With a long operation duration(6.5 h)and wireless transmission distance(20.9 m),it could fulfill most of the daily applications.Machine learning algorithms and the graphical user interface are used for real-time ECG monitoring and cardiac abnormalities diagnosis.The vibratory flexible actuator,which is triggered by cardiac abnormalities that need immediate medical treatment,is also integrated as a warning system for the user.As a newly reported stretchable multi-lead ECG device for long-term ECG signal monitoring,there is a high potential for improving users'life quality with the high-risk population of CVDs. | Chunki Yiu Yiming Liu Chao Zhang Jingkun Zhou Huiling Jia Tsz H.Wong Xingcan Huang Jian Li Kuanming Yao Ming K.Yau Ling Zhao Hu Li Binbin Zhang Wooyoung Park Yuanting Zhang Zuankai Wang Xinge Yu | 2022 | SmartMat2022，3，4： | 1 |

| 9 | Performance Evaluation of Topologies for Multi-Domain Software-Defined Networking显示文摘Software-defined networking(SDN)is widely used in multiple types of data center networks,and these distributed data center networks can be integrated into a multi-domain SDN by utilizing multiple controllers.However,the network topology of each control domain of SDN will affect the performance of the multidomain network,so performance evaluation is required before the deployment of the multi-domain SDN.Besides,there is a high cost to build real multi-domain SDN networks with different topologies,so it is necessary to use simulation testing methods to evaluate the topological performance of the multi-domain SDN network.As there is a lack of existing methods to construct a multi-domain SDN simulation network for the tool to evaluate the topological performance automatically,this paper proposes an automated multi-domain SDN topology performance evaluation framework,which supports multiple types of SDN network topologies in cooperating to construct a multi-domain SDN network.The framework integrates existing single-domain SDN simulation tools with network performance testing tools to realize automated performance evaluation of multidomain SDN network topologies.We designed and implemented a Mininet-based simulation tool that can connect multiple controllers and run user-specified topologies in multiple SDN control domains to build and test multi-domain SDN networks faster.Then,we used the tool to perform performance tests on various data center network topologies in single-domain and multi-domain SDN simulation environments.Test results show that Space Shuffle has the most stable performance in a single-domain environment,and Fat-tree has the best performance in a multi-domain environment.Also,this tool has the characteristics of simplicity and stability,which can meet the needs of multi-domain SDN topology performance evaluation. | Jiangyuan Yao Weiping Yang Shuhua Weng Minrui Wang Zheng Jiang Deshun Li Yahui Li Xingcan Cao | 2023 | Computer Systems Science & Engineering2023，47，10： | 0 |

| 12 | Fast Verification of Network Configuration Updates显示文摘With the expansion of network services,large-scale networks have progressively become common.The network status changes rapidly in response to customer needs and configuration changes,so network configuration changes are also very frequent.However,no matter what changes,the network must ensure the correct conditions,such as isolating tenants from each other or guaranteeing essential services.Once changes occur,it is necessary to verify the after-changed network.Whereas,for the verification of large-scale network configuration changes,many current verifiers show poor efficiency.In order to solve the problem ofmultiple global verifications caused by frequent updates of local configurations in large networks,we present a fast configuration updates verification tool,FastCUV,for distributed control planes.FastCUV aims to enhance the efficiency of distributed control plane verification for medium and large networks while ensuring correctness.This paper presents a method to determine the network range affected by the configuration change.We present a flow model and graph structure to facilitate the design of verification algorithms and speed up verification.Our scheme verifies the network area affected by obtaining the change of the Forwarding Information Base(FIB)before and after.FastCUV supports rich network attributes,meanwhile,has high efficiency and correctness performance.After experimental verification and result analysis,our method outperforms the state-of-the-art method to a certain extent. | Jiangyuan Yao Zheng Jiang Kaiwen Zou Shuhua Weng Yaxin Li Deshun Li Yahui Li Xingcan Cao | 2023 | Computers, Materials & Continua2023，，1： | 0 |
| 13 | Assessing the Influence of Aerosol on Radiation and Its Roles in Planetary Boundary Layer Development显示文摘A comprehensive measurement of planetary boundary layer(PBL)meteorology was conducted at 140 and 280 m on a meteorological tower in Beijing,China,to quantify the effect of aerosols on radiation and its role in PBL development.The measured variables included four-component radiation,temperature,sensible heat flux(SH),and turbulent kinetic energy(TKE)at 140 and 280 m,as well as PBL height(PBLH).In this work,a method was developed to quantitatively estimate the effect of aerosols on radiation based on the PBLH and radiation at the two heights(140 and 280 m).The results confirmed that the weakened downward shortwave radiation(DSR)on hazy days could be attributed predominantly to increased aerosols,while for longwave radiation,aerosols only accounted for around onethird of the enhanced downward longwave radiation.The DSR decreased by 55.2 W m^(-2) on hazy days during noontime(1100–1400 local time).The weakened solar radiation decreased SH and TKE by enhancing atmospheric stability,and hence suppressed PBL development.Compared with clean days,the decreasing rates of DSR,SH,TKE,and PBLH were 11.4%,33.6%,73.8%,and 53.4%,respectively.These observations collectively suggest that aerosol radiative forcing on the PBL is exaggerated by a complex chain of interactions among thermodynamic,dynamic,and radiative processes.These findings shed new light on our understanding of the complex relationship between aerosol and the PBL. | Zhigang CHENG Yubing PAN Ju LI Xingcan JIA Xinyu ZHANG Pengkun MA Qianqian WANG Junxia DOU Jingjiang ZHANG Jiannong QUAN | 2021 | Journal of Meteorological Research2021，35，2： | 0 |
| 14 | ProbD: Faulty Path Detection Based on Probability in Software-Defined Networking显示文摘With the increasing number of switches in Software-Defined Network-ing(SDN),there are more and more faults rising in the data plane.However,due to the existence of link redundancy and multi-path forwarding mechanisms,these problems cannot be detected in time.The current faulty path detection mechan-isms have problems such as the large scale of detection and low efficiency,which is difficult to meet the requirements of efficient faulty path detection in large-scale SDN.Concerning this issue,we propose an efficient network path fault testing model ProbD based on probability detection.This model achieves a high prob-ability of detecting arbitrary path fault in the form of small-scale random sam-pling.Under a certain path fault rate,ProbD obtains the curve of sample size and probability of detecting arbitrary path fault by randomly sampling network paths several times.After a small number of experiments,the ProbD model can cor-rectly estimate the path fault rate of the network and calculate the total number of paths that need to be detected according to the different probability of detecting arbitrary path fault and the path fault rate of the network.Thefinal experimental results show that,compared with the full path coverage test,the ProbD model based on probability detection can achieve efficient network testing with less overhead.Besides,the larger the network scale is,the more overhead will be saved. | Jiangyuan Yao Jiawen Wang Shuhua Weng Minrui Wang Deshun Li Yahui Li Xingcan Cao | 2023 | Intelligent Automation & Soft Computing2023，，5： | 0 |
| 15 | Memory-Occupied Routing Algorithms for Quantum Relay Networks显示文摘Quantum transmission experiments have shown that the success-ful transmission rate of entangled quanta in optical fibers decreases expo-nentially.Although current quantum networks deploy quantum relays to establish long-distance connections,the increase in transmission distance and entanglement switching costs still need to be considered when selecting the next hop.However,most of the existing quantum network models prefer to consider the parameters of the physical layer,which ignore the influence factors of the network layer.In this paper,we propose a meshy quantum network model based on quantum teleportation,which considers both net-work layer and physical layer parameters.The proposed model can reflect the realistic transmission characteristics and morphological characteristics of the quantum relay network.Then,we study the network throughput of different routing algorithms with the same given parameters when multiple source-destination pairs are interconnected simultaneously.To solve the chal-lenges of routing competition caused by the simultaneous transmission,we present greedy memory-occupied algorithm Q-GMOA and random memory-occupied algorithm Q-RMOA.The proposed meshy quantum network model and the memory-occupied routing algorithms can improve the utilization rate of resources and the transmission performance of the quantum network.And the evaluation results indicate that the proposed methods embrace a higher transmission rate than the previous methods with repeater occupation. | Jiangyuan Yao Kaiwen Zou Zheng Jiang Shuhua Weng Deshun Li Yahui Li Xingcan Cao | 2023 | Computers, Materials & Continua2023，，6： | 0 |
| 16 | Stretchable magnesium-air battery based on dual ions conducting hydrogel for intelligent biomedical applications显示文摘Flexible and bio-integrated electronics have attracted great attention due to their enormous contributions to personalized medical devices.Power sources,serving as one of the most important components,have been suffering from many problems,including deficient biocompatibility,poor stretchability,and unstable electrical outputs under deformed conditions,which limits the practical applications in flexible and bio-integrated electronics.Here,we reported a fully stretchable magnesium(Mg)–air battery based on dual-ions-conducting hydrogels(SDICH).The high-performance battery enables long-term operation with lighting 120 lighting emitting diodes(LEDs)for over 5 h.Benefiting from the advanced materials and mechanical designs,the battery exhibits stability electrical outputs under stretching,which allows to operate ordinarily under various mechanical deformations without performance decay.Furthermore,the great biocompatibility of the battery offers great opportunity for biomedical applications,which is demonstrated by a self-adaption wound dressing system.The in vitro and in vivo results prove that the self-adaption wound dressing can effectively prevent wound inflammation and promote wound healing.By exploiting thermal feedback mechanics,the system can adjust antibiotic release rate and dosage spontaneously according to the real-time wound conditions.The proposed fully stretchable Mg-air battery and self-adaption wound dressing display great potential in skin-integrated electronics and personalized medicine. | Xingcan Huang Yiming Liu Wooyoung Park Zhao Zhao Jiyu Li Chee Kent Lim Tsz Hung Wong Chun Ki Yiu Yuyu Gao Jingkun Zhou HuLi Ling Zhao Jian Li Binbin Zhang Ya Huang Rui Shi Dengfeng Li Jiaying Mo Jinpei Wang Chao Zhang Yuhang Li Zuankai Wang Xinge Yu | 2023 | InfoMat2023，5，3： | 0 |
| 17 | Exploring High-Performance Architecture for Data Center Networks显示文摘As a critical infrastructure of cloud computing,data center networks(DCNs)directly determine the service performance of data centers,which provide computing services for various applications such as big data processing and artificial intelligence.However,current architectures of data center networks suffer from a long routing path and a low fault tolerance between source and destination servers,which is hard to satisfy the requirements of high-performance data center networks.Based on dual-port servers and Clos network structure,this paper proposed a novel architecture RClos to construct high-performance data center networks.Logically,the proposed architecture is constructed by inserting a dual-port server into each pair of adjacent switches in the fabric of switches,where switches are connected in the form of a ring Clos structure.We describe the structural properties of RClos in terms of network scale,bisection bandwidth,and network diameter.RClos architecture inherits characteristics of its embedded Clos network,which can accommodate a large number of servers with a small average path length.The proposed architecture embraces a high fault tolerance,which adapts to the construction of various data center networks.For example,the average path length between servers is 3.44,and the standardized bisection bandwidth is 0.8 in RClos(32,5).The result of numerical experiments shows that RClos enjoys a small average path length and a high network fault tolerance,which is essential in the construction of high-performance data center networks. | Deshun Li Shaorong Sun Qisen Wu Shuhua Weng Yuyin Tan Jiangyuan Yao Xiangdang Huang Xingcan Cao | 2023 | Computer Systems Science & Engineering2023，46，7： | 0 |
| 18 | Generation of Low-Delay and High-Stability Multicast Tree显示文摘Delay and stability are two key factors that affect the performance of multicast data transmission in a network.However,current algorithms of tree generation hardly meet the requirements of low delay and high sta-bility simultaneously.Given a general network,the generation algorithm of a multicast tree with minimum delay and maximum stability is an NP-hard problem,without a precise and efficient algorithm.To address these challenges,this paper studies the generation of low-delay and high-stability multicast trees under the model of spanning tree based on stability probability,degree-constrained,edge-weighted for multicast(T-SDE).A class of algorithms was proposed which creates the multicast tree greedy on the ratio of fan-out to delay(RFD)and probability of stability of terminal to obtain a high performance in multicast.The proposed algorithms greedily select terminals with a large RFD and a high probability of stability as forwarding nodes in the generation of the multicast tree,where the larger RFD and higher stability of upstream nodes are beneficial to achieve a low transmission delay and high stability in multicast.The proposed RFD can be compatible with the original model,which can take advantage of network connectivity during the generation of a multicast tree.This paper carries out simulation experiments on Matlab R2016b to measure the performance of the proposed algorithm.Experimental results show that the proposed algorithm can provide a smaller height,higher stability,and a lower transmission delay of the resulting multicast tree than other solutions.The spanning tree of the proposed algorithms can support low transmission delay and high stability in multicast transmission. | Deshun Li Zhenchen Wang Yucong Wei Jiangyuan Yao Yuyin Tan Qiuling Yang Zhengxia Wang Xingcan Cao | 2023 | Computers, Materials & Continua2023，，7： | 0 |
| 19 | Electrically pumped optomechanical beam GaN-LED accelerometer based on the quantum-confined Stark effect显示文摘Micro-nano optomechanical accelerometers are widely used in automobile,aerospace,and other industrial applications.Here,we fabricate mechanical sensing components based on an electrically pumped GaN light-emitting diode(LED)with a beam structure.The relationship between the blueshift of the electroluminescence(EL)spectra and the deformation of the GaN beam structure based on the quantum-confined Stark effect(QCSE)of the InGaN quantum well(QW)structure is studied by introducing an extra mass block.Under the equivalent acceleration condition,in addition to the elastic deformation of GaN-LED,a direct relationship exists between the LED’s spectral shift and the acceleration’s magnitude.The extra mass block(gravitational force:7.55×10^(-11)N)induced blueshift of the EL spectra is obtained and shows driven current dependency.A polymer sphere(PS;gravitational force:3.427×10^(-12)N)is placed at the center of the beam GaN-LED,and a blueshift of 0.061 nm is observed in the EL spectrum under the injection current of 0.5 mA.The maximum sensitivity of the acceleration is measured to be 0.02 m∕s^(2),and the maximum measurable acceleration is calculated to be 1.8×10^(6)m∕s^(2).It indicates the simultaneous realization of high sensitivity and a broad acceleration measurement range.This work is significant for several applications,including light force measurement and inertial navigation systems with high integration ability. | GANGYI ZHU XIN JI ZHENFU ZHANG XINGCAN YAN YING YANG FEIFEI QIN XIN LI JIAGUI WU XIAOJUAN SUN JUNBO YANG YONGJIN WANG | 2023 | Photonics Research2023，11，9： | 0 |
| 20 | Thin,soft,3D printing enabled crosstalk minimized triboelectric nanogenerator arrays for tactile sensing显示文摘With the requirements of self-powering sensors in flexible electronics,wearable triboelectric nanogenerators(TENGs)have attracted great attention due to their advantages of excellent electrical outputs and low-cost processing routes.The crosstalk effect between adjacent sensing units in TENGs significantly limits the pixel density of sensor arrays.Here,we present a skin-integrated,flexible TENG sensor array with 100 sensing units in an overall size of 7.5 cm×7.5 cm that can be processed in a simple,low-cost,and scalable way enabled by 3D printing.All the sensing units show good sensitivity of 0.11 V/kPa with a wide range of pressure detection from 10 to 65 kPa,which allows to accurately distinguish various tactile formats from gentle touching(as low as 2 kPa)to hard pressuring.The 3D printing patterned substrate allows to cast triboelectric layers of polydimethylsiloxane in an independent sensing manner for each unit,which greatly suppresses the cross talk arising from adjacent sensing units,where the maximum crosstalk output is only 10.8%.The excellent uniformity and reproducibility of the sensor array offer precise pressure mapping for complicated pattern loadings,which demonstrates its potential in tactile sensing and human-machine interfaces. | Jian Li Yiming Liu Mengge Wu Kuanming Yao Zhan Gao Yuyu Gao Xingcan Huang Tsz Hung Wong Jingkun Zhou Dengfeng Li Hu Li Jiyu Li Ya Huang Rui Shi Junsheng Yu Xinge Yu | 2023 | Fundamental Research2023，3，1： | 0 |
