| 1 | Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears. | Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG | 2021 | Science China(Information Sciences)2021，64，1： | 122 |
| 2 | Direct differentiation of atrial and ventricular myocytes from human embryonic stem cells by alternating retinoid signals显示文摘尽管 myocyte 房间移植研究为心肌的梗塞建议了一个有希望的治疗学的潜力,到为心肌的修理的临床的治疗的发展的一个主要障碍是与为移植获得相对同类的室的 myocytes 联系的困难。人的胚胎的干细胞(hESCs ) 是 cardiomyocytes 的有希望的来源。这里,我们报导发信号的 retinoid 在 hESCs 的心脏的区别期间调整 atrial 对室的 myocytes 的命运说明。我们发现少量和 pan-retinoic 酸受体对手 BMS-189453 (RAi ) 显著地增加了 hESCs 的心脏的区别效率。为了调查 retinoid,工作,我们把对待 Noggin+RAi 的文化与对待 Noggin+RA 的文化作比较。我们的结果证明室特定的基因 IRX-4 的表示层次极端地在对待 Noggin+RAi 的文化被提高。MLC-2V,另一个室特定的标记,在对待 Noggin+RAi 的文化,然而并非在对待 Noggin+RA 的文化的 cardiomyocytes 在 cardiomyocytes 的多数被表示。流动 cytometry 分析和 electrophysiological 研究与 64.7 | Qiangzhe Zhang Junjie Jiang Pengcheng Han Qi Yuan Jing Zhang Xiaoqian Zhang Yanyan Xu Henghua Cao Qingzhang Meng Li Chen Tian Tian Xin Wang Pu Li Jurgen Hescheler Guangju Ji Yue Ma | 2011 | Cell Research2011，21，4： | 10 |
| 3 | A novel xeno-free and feeder-cell-free system for human pluripotent stem cell culture显示文摘While human induced pluripotent stem cells(hiPSCs)have promising applications in regenerative medicine,most of the hiPSC lines available today are not suitable for clinical applications due to contamination with nonhuman materials,such as sialic acid,and potential pathogens from animal-product-containing cell culture systems.Although several xeno-free cell culture systems have been established recently,their use of human fibroblasts as feeders reduces the clinical potential of hiPSCs due to batch-to-batch variation in the feeders and time-consuming preparation processes.In this study,we have developed a xeno-free and feeder-cell-free human embryonic stem cell(hESC)/hiPSC culture system using human plasma and human placenta extracts.The system maintains the self-renewing capacity and pluripotency of hESCs for more than 40 passages.Human iPSCs were also derived from human dermal fibroblasts using this culture system by overexpressing three transcription factors—Oct4,Sox2 and Nanog.The culture system developed here is inexpensive and suitable for large scale production. | Qihui Wang Xiaoning Mou Henghua Cao Qingzhang Meng Yanni Ma Pengcheng Han Junjie Jiang Hao Zhang Yue Ma | 2012 | Protein & Cell2012，3，1： | 6 |

| 6 | Circ_ASPH promotes cholangiocarcinoma growth and metastasis through the miR-581/ATP-binding cassette transporter G1 signaling pathway显示文摘Dear Editor,Cholangiocarcinoma(CCA)is an aggressive malignant tumor of the hepatobiliary system,mainly originating from the cholangiocytes of small intrahepatic bile ducts[1].The overall survival of patients with CCA is still unfavorable[1].Circular RNAs(circRNAs)are a type of non-coding RNAs with limited protein-coding capacity[2]and have shown to exert regulatory effects in multiple diseases by interacting with certain miRNAs to inhibit their expression and functions[3].Emerging evidence indicates that circRNAs can directly bind to several RNA-binding proteins to execute their biological functions.Hence,determining the mechanisms underlying the progression of CCA and searching for new drugs from the perspective of circRNAs are imperative. | Yi Xu Pengcheng Kang Kaiming Leng Yue Yao Guanqun Liao Yi Han Guangjun Shi Xiangyu Zhong Yunfu Cui | 2020 | Cancer Communications2020，40，10： | 1 |

| 8 | Comparative Study on Wire-Arc Additive Manufacturing and Conventional Casting of Al–Si Alloys:Porosity,Microstructure and Mechanical Property显示文摘Here,we compare the porosity,microstructure and mechanical property of 4047 Al–Si alloys prepared by wire-arc additive manufacturing(WAAM)and conventional casting.X-ray microscopy reveals that WAAM causes a higher volume fraction of gas pores in comparison with conventional casting.Effective refi nements ofα-Al dendrites,eutectic Si particles and Ferich intermetallic compounds are achieved by WAAM,resulting from its rapid solidifi cation process.Both ultimate tensile strength(UTS,up to 205.6 MPa)and yield stress(YS,up to 98.0 MPa)are improved by WAAM at the expense of elongation after fracture.The mechanical property anisotropy between scanning direction and build direction is minimal for alloys via WAAM.Additional microstructure refi nement and strength enhancement are enabled by increasing the travel speed of welding torch from 300 to 420 mm/min. | Yueling Guo Qifei Han Jinlong Hu Xinghai Yang Pengcheng Mao Junsheng Wang Shaobo Sun Zhi He Jiping Lu Changmeng Liu | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，3： | 1 |
| 9 | Joint optimization of spectral efficiency and energy efficiency with low-precision ADCs in cell-free massive MIMO systems显示文摘In cell-free massive multiple-input multiple-output(MIMO)systems,it is beneficial to apply low-precision analog-to-digital converters(ADCs)to reduce power consumption,hardware cost,and the load on backhaul link.However,low-precision ADCs will result in serious degradation in spectral efficiency(SE).It is important to achieve a good tradeoff between SE and energy efficiency(EE)for cell-free massive MIMO systems with low-precision ADCs.In this paper,we first derive the closed-form expressions of uplink achievable rates with maximal ratio combining(MRC)receiver and zero-forcing(ZF)receiver in cell-free massive MIMO systems.Then we analyze the EE model of cell-free massive MIMO systems.Based on the above analysis,the tradeoff between SE and EE is studied.Moreover,we propose two quantization bit allocation algorithms to optimize the SE and EE jointly from the perspective of multi-objective optimization.One algorithm is based on the deep Q-network(DQN)and the other one is based on the non-dominated sorting genetic algorithmⅡ(NSGA-Ⅱ).The proposed algorithms provide more feasible solutions and achieve better system performance than equal quantization bit allocation algorithm.Numerical results verify the accuracy of the derived closed-form expressions and the effectiveness of the proposed optimization algorithms. | Han WANG Chang SUN Jiamin LI Pengcheng ZHU Dongming WANG Xiaohu YOU | 2022 | Science China(Information Sciences)2022，65，5： | 1 |

| 13 | Intrinsically stretchable polymer semiconductor based electronic skin for multiple perceptions of force,temperature,and visible light显示文摘As a stretchable seamless device,electronic skin(E-skin)has drawn enormous interest due to its skin-like sensing capability.Besides the basic perception of force and temperature,multiple perception that is beyond existing functions of human skin is becoming an important direction for E-skin developments.However,the present E-skins for multiple perceptions mainly rely on different sensing materials and heterogeneous integration,resulting in a complex device structure.Additionally,their stretchability is usually achieved by the complicated microstructure design of rigid materials.Here,we report an intrinsically stretchable polymer semiconductor based E-skin with a simple structure for multiple perceptions of force,temperature,and visible light.The E-skin is on the basis of poly(3-hexylthiophene)(P3HT)nanofibers percolated polydimethylsiloxane(PDMS)composite polymer semiconductor,which is fabricated by a facile solution method.The E-skin shows reliable sensing capabilities when it is used to perceive strain,pressure,temperature,and visible light.Based on the E-skin,an intelligent robotic hand sensing and controlling system is further demonstrated.Compared with conventional E-skins for multiple perceptions,this E-skin only has a simple monolayer sensing membrane without the need of combining different sensing materials,heterogeneous integration,and complicated microstructure design.Such a strategy of utilizing intrinsically stretchable polymer semiconductor to create simple structured E-skin for multiple perceptions will promote the development of E-skins in a broad application scenario,such as artificial robotic skins,virtual reality,intelligent gloves,and biointegrated electronics. | Dongjuan Liu Pengcheng Zhu Fukang Zhang Peishuo Li Wenhao Huang Chang Li Ningning Han Shuairong Mu Hao Zhou Yanchao Mao | 2023 | Nano Research2023，16，1： | 0 |

| 16 | A Robust and Efficient Compressed Sensing Algorithm for Wideband Acoustic Imaging显示文摘Wideband acoustic imaging,which combines compressed sensing(CS)and microphone arrays,is widely used for locating acoustic sources.However,the location results of this method are unstable,and the computational efficiency is low.In this work,in order to improve the robustness and reduce the computational cost,a DCS-SOMP-SVD compressed sensing method,which combines the distributed compressed sensing using simultaneously orthogonal matching pursuit(DCS-SOMP)and singular value decomposition(SVD)is proposed.The performance of the DCS-SOMP-SVD is studied through both simulation and experiment.In the simulation,the locating results of the DCS-SOMP-SVD method are compared with the wideband BP method and the DCS-SOMP method.In terms of computational efficiency,the proposed method is as efficient as the DCS-SOMP method and more efficient than the wideband BP method.In terms of locating accuracy,the proposed method can still locate all sources when the signal to noise ratio(SNR)is−20 dB,while the wideband BP method and the DCS-SOMP method can only locate all sources when the SNR is higher than 0 dB.The performance of the proposed method can be improved by expanding the frequency range.Moreover,there is no extra source in the maps of the proposed method,even though the target sparsity is overestimated.Finally,a gas leak experiment is conducted to verify the feasibility of the DCS-SOMP-SVD method in the practical engineering environment.The experimental results show that the proposed method can locate both two leak sources in different frequency ranges.This research proposes a DCS-SOMP-SVD method which has sufficient robustness and low computational cost for wideband acoustic imaging. | Fangli Ning Zhe Liu Jiahao Song Feng Pan Pengcheng Han Juan Wei | 2020 | Chinese Journal of Mechanical Engineering2020，33，6： | 0 |
| 17 | A time sequential microfluid sensor with Tesla valve channels显示文摘The concentration of biomarkers in sweat can be used to evaluate human health,making efficient sweat sensing a focus of research.While flow channel design is often used to detect sweat velocity,it is rarely incorporated into the sensing of biomarkers,limiting the richness of sensing results.In this study,we report a time sequential sensing scheme for uric acid in sweat through a sequential design of Tesla valve channels.Graphene electrodes for detecting uric acid and directional Tesla valve flow channels were fabricated using laser engraving technology to realize time sequential sensing.The performance of the channels was verified through simulation.The time sequential detection of uric acid concentration in sweat can help researchers improve the establishment of human health management systems through flexible wearable devices. | Pengcheng Zhao Haobin Wang Yaozheng Wang Wei Zhao Mengdi Han Haixia Zhang | 2023 | Nano Research2023，16，9： | 0 |
| 18 | Effects of post annealing on the microstructure,precipitation behavior,and mechanical property of a(CoCrNi)_(94)Al_(3)Ti_(3)medium-entropy alloy fabricated by laser powder bed fusion显示文摘The additive manufacturing of multi-principal element alloys has remarkable potential for industrial ap-plications.In this study,a(CoCrNi)_(94)Al_(3)Ti_(3)medium-entropy alloy(MEA)with adequate strength-ductility synergy was prepared via laser powder bed fusion.The microstructural evolution,mechanical property,and deformation mechanisms of the MEA were investigated after post annealing for a short period(0.5 h)at a temperature range of 773-1373 K using various microstructural characterization techniques and quantitative analysis.The static recrystallization temperature of the(CoCrNi)_(94)Al_(3)Ti_(3)MEA ranged from 973 to 1073 K.The average grain size first decreased and then increased,while the dislocation den-sity persistently decreased and texture gradually weakened with increasing annealing temperature.Cr-richσ-phase precipitates formed after 1073 K and then gradually dissolved at 1373 K,while Ni,Al,and Ti elements were aggregated to form a small amount of fine L1_(2)coherent precipitates with an aver-age diameter of approximately 70 nm at 1373 K.The evolution of the dislocation density,grain size,and precipitates significantly influenced the propensity of deformation twins and stacking faults,which consequently affected the strain hardening behavior and mechanical properties.The quantitative calcu-lation of strengthening mechanisms showed that dislocation strengthening played a dominant role at annealing temperatures below 1073 K,and it significantly weakened at 1373 K.Precipitation and grain boundary strengthening both markedly increased owing to the formation of precipitation particles and recrystallization-induced grain refinement after annealing at 1073 K. | Zhuang Li Pengcheng Zhao Tiwen Lu Kai Feng Yonggang Tong Binhan Sun Ning Yao Yu Xie Bolun Han Xiancheng Zhang Shantung Tu | 2023 | Journal of Materials Science & Technology2023，，4： | 0 |
