| 1 | A nowcasting model for the prediction of typhoon tracks based on a long short term memory neural network显示文摘It is of vital importance to reduce injuries and economic losses by accurate forecasts of typhoon tracks. A huge amount of typhoon observations have been accumulated by the meteorological department, however, they are yet to be adequately utilized. It is an effective method to employ machine learning to perform forecasts. A long short term memory(LSTM) neural network is trained based on the typhoon observations during 1949–2011 in China's Mainland, combined with big data and data mining technologies, and a forecast model based on machine learning for the prediction of typhoon tracks is developed. The results show that the employed algorithm produces desirable 6–24 h nowcasting of typhoon tracks with an improved precision. | GAO Song ZHAO Peng PAN Bin LI Yaru ZHOU Min XU Jiangling ZHONG Shan SHI Zhenwei | 2018 | Acta Oceanologica Sinica2018，37，5： | 17 |
| 2 | Response of grain yield to plant density and nitrogen rate in spring maize hybrids released from 1970 to 2010 in Northeast China显示文摘The objective of this study was to identify the response of grain yield to plant density and nitrogen rate in spring maize hybrids released from 1970 to 2010 and grown extensively in Northeast China.Twenty-one hybrids were grown for 2 years in Northeast China at densities of 30,000,52,500,75,000,and 97,500 plants ha^(-1)and N application levels of 0,150,300,and 450 kg N ha^(-1).Irrespective of density or nitrogen application rate,grain yields both per plant and per unit area were significantly higher for newer than older hybrids.As plant density increased from 30,000 to 97,500 plant ha^(-1),yield per plant of 1970 s,1980 s,1990 s,and 2000 s hybrids decreased by 50%,45%,46%,and 52%,respectively.The response of grain yield per unit area to plant density was curvilinear.The estimated optimum plant densities were about 58,000,49,000,65,000,and 65,000 plants ha^(-1)for hybrids released in the 1970 s,1980s,1990 s,and 2000 s,respectively.The theoretical optimum densities for the hybrids released from the 1970 s to the 2000 s increased by 1750 plants ha^(-1)decade^(-1).Nitrogen fertilization significantly increased grain yields per plant and per unit area for all hybrids.The theoretical optimum N application rates for high yield for hybrids released in the 1970 s and 1980 s were about 280 and 360 kg ha^(-1),and the hybrids from the 1990 s and 2000 s showed highest yield at 330 kg ha^(-1)N.No significant difference in the grain yields of 2000 s hybrids between the N levels of 150 to 450 kg ha^(-1)was found.Significant yield gains per plant and per unit area were found,with average increases of 17.9 g plant^(-1)decade^(-1)and936 kg ha^(-1)decade^(-1)over the period 1970–2010,respectively.Yield gains were attributed mainly to increased yield per plant,contributed by increases in kernel number per ear and1000-kernel weight.The rates of lodging and barren plants of newer hybrids were significantly lower than those of older ones,especially at high plant density. | Chunrong Qian Yang Yu Xiujie Gong Yubo Jiang Yang Zhao Zhongliang Yang Yubo Hao Liang Li Zhenwei Song Weijian Zhang | 2016 | The Crop Journal2016，4，6： | 15 |
| 3 | Integrated(de)multiplexer for orbital angular momentum fiber communication显示文摘The quickly increasing data transfer load requires an urgent revolution in current optical communication. Orbital angular momentum(OAM) multiplexing is a potential candidate with its ability to considerably enhance the capacity of communication. However, the lack of a compact, efficient, and integrated OAM(de)multiplexer prevents it from being widely applied. By attaching vortex gratings onto the facets of a few-mode fiber, we demonstrate an integrated fiber-based OAM(de)multiplexer. A vortex grating fabricated on the fiber facet enables the direct multiplexing of OAM states at one port and the demultiplexing of OAM states at the other port. The measured bit error rate of the carrier signal after propagating through a 5-km few-mode fiber confirms the validity and effectiveness of the proposed approach. The scheme offers advantages in future high-capacity OAM communication based on optical fiber. | ZHENWEI XIE SHECHENG GAO TING LEI SHENGFEI FENG YAN ZHANG FAN LI JIANBO ZHANG ZHAOHUI LI XIAOCONG YUAN | 2018 | Photonics Research2018，6，7： | 13 |

| 6 | Ultra-broadband on-chip twisted light emitter for optical communications显示文摘On-chip twisted light emitters are essential components of orbital angular momentum(OAM)communication devices1,2.These devices address the growing demand for high-capacity communication systems by providing an additional degree of freedom for wavelength/frequency division multiplexing(WDM/FDM).Although whispering-gallery-mode-enabled OAM emitters have been shown to possess some advantages3–5,such as compactness and phase accuracy,their inherent narrow bandwidths prevent them from being compatible with WDM/FDM techniques.Here,we demonstrate an ultra-broadband multiplexed OAM emitter that utilizes a novel joint path-resonance phase control concept.The emitter has a micron-sized radius and nanometer-sized features.Coaxial OAM beams are emitted across the entire telecommunication band from 1,450 to 1,650 nm.We applied the emitter to an OAM communication with a data rate of 1.2 Tbit/s assisted by 30-channel optical frequency combs(OFCs).The emitter provides a new solution to further increase capacity in the OFC communication scenario. | Zhenwei Xie Ting Lei Fan Li Haodong Qiu Zecen Zhang Hong Wang Changjun Min Luping Du Zhaohui Li Xiaocong Yuan | 2018 | Light(Science & Applications)2018，7，1： | 7 |
| 7 | Seroprevalence of Neutralizing Antibodies against Six Human Adenovirus Types Indicates the Low Level of Herd Immunity in Young Children from Guangzhou, China显示文摘Human adenoviruses(HAdVs) commonly cause many diseases such as respiratory diseases, gastroenteritis, cystitis worldwide. HAdV-3,-7,-4 and emergent HAdV-55 and HAdV-14 are the most important types causing severe respiratory diseases. There is no effective drug available for clinical treatment, and no vaccine available for the general population.Therefore, it is important to investigate the seroprevalence against HAdV for developing novel vaccines and vectors. In this study, we investigated the seroprevalence and titer levels of neutralizing antibodies(NAb) against HAdV-3,-4,-7,-14,-55,and-11 in total 278 healthy populations between 0 months and 49 years of age(228 children and 50 adults) from Guangzhou. In children under the age of 18 years, the seropositive rates were significantly increased against HAdV-3 at12.07%, 33.96%, and 64.29% and against HAdV-7 at 0%, 18.87%, and 19.05% in age groups of 1–2, 3–5, and 6–17 years,respectively. The seroprevalence was very low(0% - 8.1%) for all other four types. In adults aged between 18 and49 years, HAdV-3,-4, and-7(> 50.00%) were the most common types, followed by HAdV-14(38.00%),-55(34.00%),and-11(24.00%). Adults tended to have high NAb titers against HAdV-4 and-55. HAdV-55-seropositive donors tended to be HAdV-11-and HAdV-14-seropositive. These results indicated the low level of herd immunity against all six HAdV types in young children, and HAdV-14,-55,-11 in adults from Guangzhou City. Our findings demonstrate the importance of monitoring HAdV types and developing vaccines against HAdV for children and adults. | Xingui Tian Ye Fan Changbing Wang Zhenwei Liu Wenkuan Liu Yun Xu Chuncong Mo Aiping You Xiao Li Xia Rong Rong Zhou | 2021 | Virologica Sinica2021，36，3： | 5 |

| 9 | Probing the limits of plasmonic enhancement using a two-dimensional atomic crystal probe显示文摘Achieving larger electromagnetic enhancement using a nanogap between neighboring metallic nanostructures has been long pursued for boosting light–matter interactions.However,the quantitative probing of this enhancement is hindered by the lack of a reliable experimental method for measuring the local fields within a subnanometer gap.Here,we use layered MoS2 as a two-dimensional atomic crystal probe in nanoparticle-on-mirror nanoantennas to measure the plasmonic enhancement in the gap by quantitative surface-enhanced Raman scattering.Our designs ensure that the probe filled in the gap has a well-defined lattice orientation and thickness,enabling independent extraction of the anisotropic field enhancements.We find that the field enhancement can be safely described by pure classical electromagnetic theory when the gap distance is no<1.24 nm.For a 0.62 nm gap,the probable emergence of quantum mechanical effects renders an average electric field enhancement of 114-fold,38.4%lower than classical predictions. | Wen Chen Shunping Zhang Meng Kang Weikang Liu Zhenwei Ou Yang Li Yexin Zhang Zhiqiang Guan Hongxing Xu | 2018 | Light(Science & Applications)2018，7，1： | 4 |
| 10 | LncDACH1 promotes mitochondrial oxidative stress of cardiomyocytes by interacting with sirtuin3 and aggravates diabetic cardiomyopathy显示文摘Diabetic cardiomyopathy(DCM)is a common complication in diabetic patients.The molecular mechanisms of DCM remain to be fully elucidated.The intronic long noncoding RNA of DACH1(lnc DACH1)has been demonstrated to be closely associated with heart failure and cardiac regeneration.In this study,we investigated the role of lnc DACH1 in DCM and the underlying molecular mechanisms.The expression of lnc DACH1 was increased in DCM hearts and in high glucose-treated cardiomyocytes.Knockout of lnc DACH1 reduced mitochondrial oxidative stress,cell apoptosis,cardiac fibrosis and hypertrophy,and improved cardiac function in DCM mice.Overexpression of lnc DACH1 exacerbated mitochondria-derived reactive oxygen species(ROS)level and apoptosis,decreased activity of manganese superoxide dismutase(Mn-SOD);while silencing of lnc DACH1 attenuated ROS production,mitochondrial dysfunction,cell apoptosis,and increased the activity of Mn-SOD in cardiomyocytes treated with high glucose.Lnc DACH1 directly bound to sirtuin3(SIRT3)and facilitated its degradation by ubiquitination,therefore promoting mitochondrial oxidative injury and cell apoptosis in mouse hearts.In addition,SIRT3 silencing abrogated the protective effects of lnc DACH1 deficiency in cardiomyocytes.In summary,lnc DACH1 aggravates DCM by promoting mitochondrial oxidative stress and cell apoptosis via increasing ubiquitination-mediated SIRT3 degradation in mouse hearts.Inhibition of lnc DACH1 represents a novel therapeutic strategy for the intervention of diabetic cardiomyopathy. | Qi Zhang Danyang Li Xue Dong Xiaowen Zhang Junwu Liu Lili Peng Bo Meng Qi Hua Xinyu Pei Lu Zhao Xiaoxi Hu Yang Zhang Zhenwei Pan Yanjie Lu Baofeng Yang | 2022 | Science China(Life Sciences)2022，65，6： | 4 |
| 11 | CMOS-compatible all-optical modulator based on the saturable absorption of graphene显示文摘Graphene resting on a silicon-on-insulator platform offers great potential for optoelectronic devices.In the paper,we demonstrate all-optical modulation on the graphene-silicon hybrid waveguides(GSHWs)with tens of micrometers in length.Owing to strong interaction between graphene and silicon strip waveguides with compact light confinement,the modulation depth reaches 22.7%with a saturation threshold down to 1.38 pJ per pulse and a 30-μm-long graphene pad.A response time of 1.65 ps is verified by a pump-probe measurement with an energy consumption of 2.1 pJ.The complementary metal-oxide semiconductor compatible GSHWs with the strip configuration exhibit great potential for ultrafast and broadband all-optical modulation,indicating that employing two-dimensional materials has become a complementary technology to promote the silicon photonic platform. | HONG WANG NINGNING YANG LIMIN CHANG CHAOBIAO ZHOU SHIYU LI MENG DENG ZHENWEI LI QIANG LIU CHI ZHANG ZHIYONG LI YI WANG | 2020 | Photonics Research2020，8，4： | 4 |
| 12 | OsbZIP60-mediated unfolded protein response regulates grain chalkiness in rice显示文摘Grain chalkiness,an undesirable trait caused by complex factors,has great negative impacts on the quality and economic value of rice.However,little is known about the regulatory mechanism of grain chalkiness,particularly the effect of endoplasmic reticulum(ER)stress.Here,a genome-wide association study(GWAS)reveals that the transcription factor Osb ZIP60 is a vital regulator of rice grain chalkiness.Genetic analysis demonstrates that knockout of Osb ZIP60 results in extremely high grain chalkiness and aberrant structure of storage substances.Notably,the expression of unfolded protein response(UPR)genes,such as OsbZIP50,Os Bi P1,Os Bi P2 and Os Bi P3,is up-regulated in the endosperm cells of osbzip60,and overexpression of all these UPR genes causes various degrees of chalkiness.Furthermore,Osb ZIP60 is found to activate the expression of key genes related to grain chalkiness,such as GPA3,FSE1,FLO7,Chalk5,Os NF-YB1,and Os PK2,whose expression is significantly suppressed in osbzip60 and overexpression lines of Osb ZIP50,Os Bi P1,Os Bi P2,and Os Bi P3.Our study provides novel insights into the function of Osb ZIP60 and the role of the UPR pathway in the formation of grain chalkiness in rice. | Weiping Yang Pengkun Xu Juncheng Zhang Shuo Zhang Zhenwei Li Ke Yang Xinyuan Chang Yibo Li | 2022 | Journal of Genetics and Genomics2022，49，5： | 4 |

| 14 | Safety of endovascular therapy for symptomatic intracranial artery stenosis:a national prospective registry显示文摘Introduction The safety outcomes of endovascular therapy for intracranial artery stenosis in a real-world stetting are largely unknown.The Clinical Registration Trial of Intracranial Stenting for Patients with Symptomatic Intracranial Artery Stenosis(CRTICAS)was a prospective,multicentre,real-world registry designed to assess these outcomes and the impact of centre experience.Methods 1140 severe,symptomatic intracranial arterial stenosis(ICAS)patients treated with endovascular therapy were included from 26 centres,further divided into three groups according to the annual centre volume of intracranial angioplasty and stent placement procedures over 2 years:(1)high volume for≥25 cases/year;(2)moderate volume for 10–25 cases/year and(3)low volume for<10 cases/year.Results The rate of 30-day stroke,transient ischaemic attack or death was 9.7%(111),with 5.4%,21.1%and 9.7%in high-volume,moderate-volume and low-volume centres,respectively(p<0.05).Multivariable logistic regression confirmed high-volume centres had a significantly lower primary endpoint compared with moderate-volume centres(OR=0.187,95%CI:0.056 to 0.627;p≤0.0001),while moderate-volume and low-volume centres showed no significant difference(p=0.8456).Conclusion Compared with the preceding randomised controlled trials,this real-world,prospective,multicentre registry shows a lower complication rate of endovascular treatment for symptomatic ICAS.Non-uniform utilisation in endovascular technology,institutional experience and patient selection in different volumes of centres may have an impact on overall safety of this treatment. | Yabing Wang Tao Wang Adam Andrew Dmytriw Kun Yang Liqun Jiao Huaizhang Shi Jie Lu Tianxiao Li Yujie Huang Zhenwei Zhao Wei Wu Jieqing Wan Qinjian Sun Bo Hong Yongli Li Liyong Zhang Jianfeng Chu Qiong Cheng Yiling Cai Pengfei Wang Qi Luo Hua Yang Baijing Dong Yang Zhang Jun Zhao Zuoquan Chen Wei Li Xiaoxin Bai Weiwen He Xueli Cai Maimai Ti Osama O Zaidat | 2022 | Stroke & Vascular Neurology2022，7，2： | 3 |

| 16 | Acetytation of ACAP4 regutates CCL18-elicited breast cancer cell migration and invasion显示文摘Tumor metastasis represents the main causes of cancer-related death.Our recent study showed that chemokine CCL18 secreted from tumor-associated macrophages regulates breast tumor metastasis,but the underlying mechanisms remain less clear.Here, we show that ARF6 GTPase-activating protein ACAP4 regulates CCL18-elicited breast cancer cell migration via the acetyltransferase PCAF-mediated acetylation.CCL18 stimulation elicited breast cancer cell migration and invasion via PCAF-dependent acetylation.ACAP4 physically interacts with PCAF and is a cognate substrate of PCAF during CCL18 stimulation.The acetylation site of ACAP4 by PCAF was mapped to Lys311 by mass spectrometric analyses.Importantly,dynamic acetylation of ACAP4 is essential for CCL18-induced breast cancer cell migration and invasion,as overexpression of the persistent acetylation-mimicking or nonacetylatable ACAP4 mutant blocked CCL18-elicited cell migration and invasion.Mechanistically,the acetylation of ACAP4 at Lys311 reduced the lipid-binding activity of ACAP4 to ensure a robust and dynamic cycling of ARF6-ACAP4 complex with plasma membrane in response to CCL18 stimulation.Thus,these results present a previously undefined mechanism by which CCL18-elicited acetylation of the PH domain controls dynamic interaction between ACAP4 and plasma membrane during breast cancer cell migration and invasion. | Xiaoyu Song Wei Liu Xiao Yuan Jiying Jiang Wanjuan Wang McKay Mullen Xuannv Zhao Yin Zhang Fusheng Liu Shihao Du Adeel Rehman Ruijun Tian Jian Li Andra Frost Zhenwei Song Hadiyah-Nicole Green Calmour Henry Xing Liu Xia Ding Dongmei Wang Xuebiao Yao | 2018 | Journal of Molecular Cell Biology2018，10，6： | 3 |
| 17 | Optical orbital angular momentum multiplexing communication via inversely-designed multiphase plane light conversion显示文摘Multiplexing and demultiplexing of optical orbital angular momentum(OAM)are critical operations in modedivision multiplexing communications.Traditional Dammann gratings,spiral phase planes,and optical geometric transformations are regarded as convenient methods for OAM mode(de)multiplexing.However,crosstalk between the different modes and the difficulty of mode multiplexing greatly limit their application to modedivision multiplexing communications.Here,using a set of inversely-designed phase planes,we demonstrate an OAM(de)multiplexer based on multiphase plane light conversion that can enable perfect OAM multiplexing communication.The sorted patterns are Gaussian-like and can be coupled easily into single-mode fiber arrays.Inputs from the fiber array are turned into coaxial OAM modes after the phase planes.OAM mode crosstalk generated by the multiplexer is less than-20 d B,with insertion loss of less than 2.6 d B.OAM modes are sorted by the demultiplexer with mode crosstalk below-10 d B,and the sorting results are coupled to the fiber array.OAM modes carrying 10 Gbit/s on–off keying signals were transmitted in a 5 km few-mode fiber.The measured bit-error-rate curves have power penalties of less than 10 d B.The proposed configuration is highly efficient and convenient and will be beneficial for potential applications in quantum information,information processing,and optical communications. | JUNCHENG FANG JINPEI LI ARU KONG YOUPENG XIE CHUXUAN LIN ZHENWEI XIE TING LEI XIAOCONG YUAN | 2022 | Photonics Research2022，10，9： | 3 |
| 18 | Revisiting the breakdown of Stokes-Einstein relation in glassforming liquids with machine learning显示文摘The Stokes-Einstein(SE) relation has been considered as one of the hallmarks of dynamics in liquids. It describes that the diffusion constant D is proportional to(τ/T)–1, where τ is the structural relaxation time and T is the temperature. In many glassforming liquids, the breakdown of SE relation often occurred when the dynamics of the liquids becomes glassy, and its origin is still debated among many scientists. Using molecular dynamics simulations and support-vector machine method, it is found that the scaling between diffusion and relaxation fails when the total population of solid-like clusters shrinks at the maximal rate with decreasing temperature, which implies a dramatic unification of clusters into an extensive dominant one occurs at the time of breakdown of the SE relation. Our data leads to an interpretation that the SE violation in metallic glass-forming liquids can be attributed to a specific change in the atomic structures. | ZhenWei Wu Renzhong Li | 2020 | Science China(Physics,Mechanics & Astronomy)2020，63，7： | 2 |
| 19 | Passively Q-switched erbium doped fiber laser using a gold nanostars based saturable absorber显示文摘In this paper, we propose and demonstrate an all-fiber passively Q-switched erbium doped fiber laser(EDFL) by using gold nanostars(GNSs) as a saturable absorber(SA) for the first time, to the best of our knowledge. In comparison with other gold nanomorphologies, GNSs have multiple localized surface plasmon resonances, which means that they can be used to construct wideband ultrafast pulse lasers. By inserting the GNS SA into an EDFL cavity pumped by a 980 nm laser diode, a stable passively Q-switched laser at 1564.5 nm was achieved for a threshold pump power of 40 mW. By gradually increasing the pump power from 40 to 120 mW, the pulse duration decreases from 12.8 to 5.3 μs and the repetition rate increases from 10 to 17 kHz. Our results indicate that the GNSs are a promising SA for constructing pulse lasers. | ZHE KANG MINGYI LIU ZHENWEI LI SIQING LI ZHIXU JIA CHENGZHI LIU WEIPING QIN GUANSHI QIN | 2018 | Photonics Research2018，6，6： | 2 |
| 20 | Novel titanium dioxide ceramics containing bismuth and antimony显示文摘Here,we developed one kind of novel TiO_(2) ceramics with colossal dielectric constant by chemical modifications(Bi^(3+) and Sb^(5+)),and discussed the physical origin for giant dielectric constant.Effects of Bi and/or Sb on their microstructure,dielectric properties as well as its frequency and temperature stability were studied in detail.It was found that their dielectric properties are strongly sensitive to(Bi,Sb)contents,and colossal dielectric permittivity(CP)(10^(4)~10^(5))together with low dielectric loss(~5.7%)can be obtained in a wide composition range.In addition,all the ceramics possessed good frequency(10^(2)~10^(6)Hz)and temperature(-150-200℃)stability of dielectric properties.In addition,the defects caused by the Bi volatilization may be the reason for higher dielectric properties of(Bi_(0.5)Sb_(0.5))_(x)Ti_(1-x)O_(2) ceramics with respect to(A_(0.5)Sb_(0.5))_(x)Ti_(1-x)O_(2)(A=In,Pr,Dy,Sm,Gd,Yb,Ga,Al,Fe or Sc).According to the results of complex impedance and XPS,the electron-pinned defect-dipoles may be suitable to explain the CP phenomenon,and oxygen vacancies-induced by Bi^(3+)&Sb^(5+) substitution for Ti^(4+) should be responsible for conduction mechanism.We believe that this profound investigation can benefit the development of TiO_(2) ceramics as a CP material. | Zhenwei Li Jiagang Wu | 2017 | Journal of Materiomics2017，3，2： | 2 |
