| 1 | Ultrasensitive terahertz metamaterial sensor based on vertical split ring resonators显示文摘An ultrasensitive metamaterial sensor based on double-slot vertical split ring resonators(DVSRRs) is designed and numerically calculated in the terahertz frequency. This DVSRR design produces a fundament LC resonance with a quality factor of about 20 when the incidence magnetic field component normal to the DVSRR array. The resonant characteristics and sensing performance of the DVSRR array design are systematically analyzed employing a contrast method among three similar vertical split ring resonator(SRRs) structures. The research results show that the elimination of bianisotropy, induced by the structural symmetry of the DVSRR design, helps to achieve LC resonance of a high quality factor. Lifting the SRRs up from the substrate sharply reduces the dielectric loss introduced by the substrate. All these factors jointly result in superior sensitivity of the DVSRR to the attributes of analytes. The maximum refractive index sensitivity is 788 GHz/RIU or 1.04 × 10~5 nm∕RIU.Also, the DVSRR sensor maintains its superior sensing performance for fabrication tolerance ranging from -4% to 4% and wide range incidence angles up to 50° under both TE and TM illuminations. | WEI WANG FENGPING YAN SIYU TAN HONG ZHOU YAFEI HOU | 2017 | Photonics Research2017，5，6： | 9 |
| 2 | Flooding attack and defence in Ad hoc networks显示文摘Mobile ad hoc networks are particularly vulnerable to denial of service (DOS) attacks launched through compromised nodes or intruders. In this paper, we present a new DOS attack and its defense in ad hoc networks. The new DOS attack,called Ad hoc Flooding Attack(AHFA), is that intruder broadcasts mass Route Request packets to exhaust the communication bandwidth and node resource so that the valid communication can not be kept. After analyzed Ad hoc Flooding Attack, we develop Flooding Attack Prevention (FAP), a generic defense against the Ad hoc Flooding Attack. When the intruder broadcasts exceeding packets of Route Request, the immediate neighbors of the intruder record the rate of Route Request. Once the threshold is exceeded, nodes deny any future request packets from the intruder. The results of our implementation show FAP can prevent the Ad hoc Flooding attack efficiently. | Yi Ping Hou Yafei Zhong Yiping Zhang Shiyong Dai Zhoulin | 2006 | Journal of Systems Engineering and Electronics2006，17，2： | 5 |
| 3 | Noise-like pulse generation from a thulium-doped fiber laser using nonlinear polarization rotation with different net anomalous dispersion显示文摘A mode-locked thulium-doped fiber laser(TDFL) based on nonlinear polarization rotation(NPR) with different net anomalous dispersion is demonstrated. When the cavity dispersion is-1.425 ps^2, the noise-like(NL) pulse with coherence spike width of 406 fs and pulse energy of 12.342 nJ is generated at a center wavelength of 2003.2 nm with 3 dB spectral bandwidth of 23.20 nm. In the experimental period of 400 min, the 3 dB spectral bandwidth variation, the output power fluctuation, and the central wavelength shift are less than 0.06 nm, 0.04 d B, and0.4 nm, respectively, indicating that the NPR-based TDFL operating in the NL regime holds good long-term stability. | Shuo Liu Fengping Yan Yang Li Luna Zhang Zhuoya Bai Hong Zhou Yafei Hou | 2016 | Photonics Research2016，4，6： | 5 |

| 5 | High-efficiency second-order nonlinear processes in an optical microfibre assisted by few-layer GaSe显示文摘The centrosymmetric nature of silica fibre precludes the realisation of second-order nonlinear processes in optical fibre systems.Recently,the integration of 2D materials with optical fibres has opened up a great opportunity to develop allfibre active devices.Here,we demonstrate high-efficiency second-order nonlinear frequency conversions in an optical microfibre assisted with few-layer gallium selenide(GaSe)nanoflakes.Attributed to the strong evanescent field of the microfibre and ultrahigh second-order nonlinearity of the GaSe nanoflakes,second harmonic generation(SHG)and sum-frequency generation(SFG)are effectively achieved with only sub-milliwatt continuous-wave(CW)lasers in the wavelength range of 1500–1620 nm,covering the C and L telecom bands.The SHG intensity from the microfibre is enhanced by more than four orders of magnitude with the assistance of the GaSe nanoflakes on fibre nonlinear processes.Moreover,in the SFG process,the intensity transfer between different frequencies can be effectively manipulated by changing the wavelengths and powers of two pump lasers.The realised strong second-order nonlinearity in the GaSe-integrated microfibre might expand the applications of all-fibre devices in all-optical signal processing and new light source generation at awkward wavelengths. | Biqiang Jiang Zhen Hao Yafei Ji Yueguo Hou Ruixuan Yi Dong Mao Xuetao Gan Jianlin Zhao | 2020 | Light(Science & Applications)2020，9，1： | 4 |
| 6 | 3D hierarchical microspheres constructed by ultrathin MoS2-C nanosheets as high-performance anode material for sodium-ion batteries显示文摘MoS2/C composites are considered to have great application potential in sodium-ion batteries(SIBs).It is a challenging and meaningful subject that developing high-performance anode materials via combining MoS2 and carbon effectively to give free rein to their advantages in sodium ion storage.In this work,a novel MoS2-C material was designed by using cellulose nanocrystals(CNCs)as low-cost and green carbon source.3 D hierarchical microspheres(200-250 nm)constructed by ultrathin MoS2-C nanosheets were synthesized by synchronizing the pre-carbonization of CNCs with the formation of MoS2 in hydrothermal reaction and subsequent pyrolysis process.It is found that the ultrathin MoS2-C nanosheets were composed of CNCs-derived short-range ordered carbon and few-layered MoS2.Benefiting from the unique structure and robust combination of MoS2 and CNCs-derived carbon,the ultrathin MoS2-C nanosheets composite was proved to have excellent cycling stability and superior rate performance in sodium-ion half-cell test and have high first reversible specific capacity of 397.9 m Ah/g in full-cell test.This work provides a significant and effective pathway to prepare MoS2-C materials with excellent electrochemical performance for the application in large-scale energy storage systems. | Wenlong Zhang Haihui Zhou Zhongyuan Huang Songlin Li Chuqing Wang Huanxin Li Zhanheng Yan Teng Hou Yafei Kuang | 2020 | Journal of Energy Chemistry2020，29，10： | 3 |
| 7 | Enhancing sensing capacity of terahertz metamaterial absorbers with a surface-relief design显示文摘Metamaterial absorbers(MAs)serve as important electromagnetic wave-absorbing devices that have captured the attention of researchers for a long term.Functioning as sensitive detectors to determine perturbations in an ambient environment is another significant subsidiary function.Here,we theoretically propose an optimized fabrication method to implement terahertz MAs with fewer steps and also evaluate both absorption and sensing performances of such MAs realized by the new method.Simulation findings demonstrate that such MAs can basically maintain the original absorption features perfectly,including near-complete absorption at resonance as well as strong robustness to wide incident angles.Specifically,the full width at half-maximum and quality factor of the absorption resonances attenuate less than 26%and 8%with this new method,remaining in the ranges of^0.03–0.04 THz and^20–27 for two selected example MAs.More significantly,sensing capacities of this type of MA,in terms of maximum detection range(enhancing at least 9%),observable spectral modulation(increasing at least 6.3%),and refractive index sensitivity,are improved to a large extent because of more intense coupling between resonant field and matter in the case of surface-relief MAs.This stronger coupling results from exposing more spots of the resonantly high field to direct contact with an approaching analyte,which is illustrated by field profiles of the MAs at resonance in this work.Additionally,other desirable absorber features are also explored with such MAs,like functioning as building blocks to configure multiband MAs and strong robustness against fabrication errors.Such new-style terahertz MAs shown in the paper,acting as good examples,not only prove that terahertz MAs can be fabricated by the proposed time-and cost-saving route in contrast to the traditional MA fabrication process,but also can serve as novel platforms to explore other intriguing terahertz photonic effects,such as the field enhancement effect. | WEI WANG FENGPING YAN SIYU TAN HAISU LI XUEMEI DU LUNA ZHANG ZHUOYA BAI DAN CHENG HONG ZHOU YAFEI HOU | 2020 | Photonics Research2020，8，4： | 3 |

| 9 | NiCo_(2)S_(4)/N microspheres grown on N,S co-doped reduced graphene oxide as an efficient bifunctional electrocatalyst for overall water splitting in alkaline and neutral pH显示文摘It is of vital importance to design efficient and low-cost bifunctional catalysts for the electrochemical water splitting under alkaline and neutral pH conditions.In this work,we report an efficient and stable NiCo_(2)S_(4)/N,S co-doped reduced graphene oxide(NCS/NS-rGO)electrocatalyst for water splitting,in which NCS microspheres are composed of one-dimentional(1D)nanorods grown homogeneously on the surface of NS-rGOs).The synergetic effect,abundant active sites,and hybridization of NCS/NS-rGO endow their outstanding electrocatalytic performance for hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)in both alkaline and neutral conditions.Furthermore,NCS/NS-rGO employed as both anode and cathode in a two-electrode alkaline and neutral system electrolyzers deliver 10 mA/cm^(2) with the low cell voltage of 1.58 V in alkaline and 1.91 V in neutral condition.These results illustrate the rational design of carbon-supported nickel-cobalt based bifunctional materials for practical water splitting over a wide pH range. | Haoquan Li Long Chen Pengfei Jin Yafei Li Jianxiang Pang Juan Hou Shanglong Peng Gang Wang Yulin Shi | 2022 | Nano Research2022，15，2： | 1 |

| 11 | Homotypic clustering of L1 and B1/Alu repeats compartmentalizes the 3D genome显示文摘Organization of the genome into euchromatin and heterochromatin appears to be evolutionarily conserved and relatively stable during lineage differentiation.In an effort to unravel the basic principle underlying genome folding,here we focus on the genome itself and report a fundamental role for L1(LINE1 or LINE-1)and B1/Alu retrotransposons,the most abundant subclasses of repetitive sequences,in chromatin compartmentalization.We find that homotypic clustering of L1 and B1/Alu demarcates the genome into grossly exclusive domains,and characterizes and predicts Hi-C compartments.Spatial segregation of L1-rich sequences in the nuclear and nucleolar peripheries and B1/Alu-rich sequences in the nuclear interior is conserved in mouse and human cells and occurs dynamically during the cell cycle.In addition,de novo establishment of L1 and B1 nuclear segregation is coincident with the formation of higher-order chromatin structures during early embryogenesis and appears to be critically regulated by L1 and B1 transcripts.Importantly,depletion of L1 transcripts in embryonic stem cells drastically weakens homotypic repeat contacts and compartmental strength,and disrupts the nuclear segregation of L1-or B1-rich chromosomal sequences at genome-wide and individual sites.Mechanistically,nuclear co-localization and liquid droplet formation of L1 repeat DNA and RNA with heterochromatin protein HP1αsuggest a phase-separation mechanism by which L1 promotes heterochromatin compartmentalization.Taken together,we propose a genetically encoded model in which L1 and B1/Alu repeats blueprint chromatin macrostructure.Our model explains the robustness of genome folding into a common conserved core,on which dynamic gene regulation is overlaid across cells. | J.Yuyang Lu Lei Chang Tong Li Ting Wang Yafei Yin Ge Zhan Xue Han Ke Zhang Yibing Tao Michelle Percharde Liang Wang Qi Peng Pixi Yan Hui Zhang Xianju Bi Wen Shao Yantao Hong Zhongyang Wu Runze Ma Peizhe Wang Wenzhi Li Jing Zhang Zai Chang Yingping Hou Bing Zhu Miguel Ramalho-Santos Pilong Li Wei Xie Jie Na Yujie Sun Xiaohua Shen | 2021 | Cell Research2021，31，6： | 1 |

| 13 | Plants response to light stress显示文摘Plants require solar energy to grow through oxygenic photosynthesis;however,when light intensity exceeds the optimal range for photosynthesis,it causes abiotic stress and physiological damage in plants.In response to high light stress,plants initiate a series of signal transduction from chloroplasts to whole cells and from locally stressed tissues to the rest of the plant body.These signals trigger a variety of physiological and biochemical reactions intended to mitigate the deleterious effects of high light intensity,such as photodamage and photoinhibition.Light stress protection mechanisms include chloroplastic Reactive oxygen species(ROS)scavenging,chloroplast and stomatal movement,and anthocyanin production.Photosynthetic apparatuses,being the direct targets of photodamage,have also developed various acclimation processes such as thermal energy dissipation through nonphotochemical quenching(NPQ),photorepair of Photosystem II(PSII),and transcriptional regulation of photosynthetic proteins.Fluctuating light is another mild but persistent type of light stress in nature,which unfortunately has been poorly investigated.Current studies,however,suggest that state transitions and cyclic electron transport are the main adaptive mechanisms for mediating fiuctuating light stress in plants.Here,we review the current breadth of knowledge regarding physiological and biochemical responses to both high light stress and fiuctuating light stress. | Yafei Shi Xiangsheng Ke Xiaoxia Yang Yuhan Liu Xin Hou | 2022 | Journal of Genetics and Genomics2022，49，8： | 1 |

| 17 | Distribution Assessment and Source Identification Using Multivariate Statistical Analyses and Artificial Neutral Networks for Trace Elements in Agricultural Soils in Xinzhou of Shanxi Province, China显示文摘Multivariate statistical analyses were used to assess the contents and distributions of trace elements in agricultural soils in Xinzhou of Shanxi Province, China, and to identify their sources. Samples with high levels of trace elements were concentrated in eastern Xinzhou, with contents declining from the east to west. Principal component and redundancy analyses revealed strong correlations among Co, Cu, Mn, Ni, Se, V, and Zn contents, suggesting that these elements were derived from similar parent materials. There were also strong correlations between the contents of these elements and soil properties. Contents of Cd and Pb were significantly higher in the agricultural soil samples than in the background soil samples(P < 0.05), and were higher in areas with higher levels of gross domestic product but decreased with distance to the nearest road. Therefore, human activities appear to have a strong influence on the Cd and Pb distribution patterns. A novel artificial neural network(ANN) model, using environmental input data, was used to predict the soil Cd and Pb contents of specified test dates. The performances of the ANN model and a traditional multilinear model were compared. The ANN model could successfully predict Cd and Pb content distributions, projecting that soil Cd and Pb contents will increase by 128% and 25%, respectively, by 2020. The results thus indicated that the economic condition of an area has a greater effect on trace element contents and distributions in the soil than the scale of the economy itself. | SHANGGUAN Yuxian CHENG Bin ZHAO Long HOU Hong MA Jin SUN Zaijin XU Yafei ZHAO Ruifen ZHANG Yigong HUA Xiaozan HUO Xiaolan ZHAO Xiufeng | 2018 | Pedosphere2018，28，3： | 1 |
| 18 | Physical Activity,Sedentary Behavior,and the Risk of Cardiovascular Disease in Type 2 Diabetes Mellitus Patients:The MIDiab Study显示文摘The aim of this study was to explore the associations of moderate-to-vigorous-intensity physical activity(MVPA)time and sedentary(SED)time with a history of cardiovascular disease(CVD)and multifactorial(i.e.,blood pressure(BP),body mass index(BMI),low-density lipoprotein cholesterol(LDL-C),and glycated hemoglobin A1c(HbA1c))control status among type 2 diabetes mellitus(T2DM)patients in China.A cross-sectional analysis of 9152 people with type 2 diabetes from the Multifactorial Intervention on Type 2 Diabetes(MIDiab)study was performed.Patients were grouped according to their self-reported MVPA time(low,<150 min·week−1;moderate,150 to<450 min·week−1;high,≥450 min·week−1)and SED time(low,<4 h·d–1;moderate,4 to<8 h·d–1;high,≥8 h·d–1).Participants who self-reported a history of CVD were identified as having a CVD risk.Odds ratios(ORs)and 95%confidence intervals(CIs)of CVD risk and multifactorial control status associated with MVPA time and SED time were estimated using mixed-effect logistic regression models,adjusting for China’s geographical region characteristics.The participants had a mean±standard deviation(SD)age of(60.87±8.44)years,44.5%were women,and 25.1%had CVD.After adjustment for potential confounding factors,an inverse association between high MVPA time and CVD risk that was independent of SED time was found,whereas this association was not observed in the moderate-MVPA group.A higher MVPA time was more likely to have a positive effect on the control of BMI.Compared with the reference group(i.e.,those with MVPA time≥450 min·week−1 and SED time<4 h·d–1),CVD risk was higher in the low-MVPA group:The OR associated with an SED time<4 h·d–1 was 1.270(95%CI,1.040–1.553)and that associated with an SED time≥8 h·d–1 was 1.499(95%CI,1.149–1.955).We found that a high MVPA time(i.e.,≥450 min·week−1)was associated with lower odds of CVD risk regardless of SED time among patients with T2DM. | Yafei Wu Guijun Qin Guixia Wang Libin Liu Bing Chen Qingbo Guan Zhongshang Yuan Xu Hou Ling Gao Chao Xu Haiqing Zhang Xu Zhang Qiu Li Yongfeng Song Fei Jing Shizhan Ma Shanshan Shao Meng Zhao Qingling Guo Nanwei Tong Hongyan Zhao Xiaomin Xie Chao Liu Zhongyan Shan Zhifeng Cheng Xuefeng Yu Shulin Chen Tao Yang Yangang Wang Dongmei Li Zhaoli Yan Lixin Guo Qiuhe Ji Wenjuan Wang Jiajun Zhao | 2023 | Engineering2023，，1： | 1 |
| 19 | Arginine-peptide complex-based assemblies to combat tumor hypoxia for enhanced photodynamic therapeutic effect显示文摘Tumor hypoxia is one of the major factors restricting the photodynamic therapy(PDT)efficacy.To address this problem,we designed an arginine-peptide complex,namely Fluorenylmethoxycarbonyl-Leucine-Leucine-Leucine-Arginine-OH(Fmoc-L_(3)-Arg),which is able to co-assemble with 5,10,15,20-Tetrakis(4-hydroxyphenyl)porphyrin(THPP)into stable nanoparticles(NPs)with uniform and spherical shapes.The THPP/Fomc-L_(3)-Arg NPs were ultra-sensitive to tumorous acidic and oxidative conditions,and could rapidly release photosensitizers in tumor cells.Meanwhile,the co-loaded Fmoc-L_(3)-Arg could efficiently generate nitric oxide(NO),inhibiting mitochondrial cellular respiration and increasing oxygen in tumor cells to support the profound improvement of reactive oxygen species(ROS)yield and PDT efficacy.After intravenous injection,the THPP/Fomc-L_(3)-Arg NPs greatly accumulated at tumor tissue and significantly inhibited tumor growth upon irradiation.In conclusion,such an arginine-peptide complex-based nanoassembly addresses the inevitable problem of hypoxia-induced tumor resistance to PDT. | Yanxian Hou Yafei Kuang Qikun Jiang Shuang Zhou Jiang Yu Zhonggui He Jin Sun | 2022 | Nano Research2022，15，6： | 0 |
| 20 | Continuous-Variable Quantum Network Coding Based on Quantum Discord显示文摘Establishing entanglement is an essential task of quantum communication technology.Beyond entanglement,quantum discord,as a measure of quantum correlation,is a necessary prerequisite to the success of entanglement distribution.To realize efficient quantum communication based on quantum discord,in this paper,we consider the practical advantages of continuous variables and propose a feasible continuous-variable quantum network coding scheme based on quantum discord.By means of entanglement distribution by separable states,it can achieve quantum entanglement distribution from sources to targets in a butterfly network.Compared with the representative discrete-variable quantum network coding schemes,the proposed continuous-variable quantum network coding scheme has a higher probability of entanglement distribution and defends against eavesdropping and forgery attacks.Particularly,the deduced relationship indicates that the increase in entanglement is less than or equal to quantum discord. | Tao Shang Ran Liu Jianwei Liu Yafei Hou | 2020 | Computers, Materials & Continua2020，，9： | 0 |
