| 1 | U-Pb zircon geochronology and Hf isotope study of metamorphosed basic-ultrabasic rocks from metamorphic basement in southwestern Zhejiang:The response of the Cathaysia Block to Indosinian orogenic event显示文摘A combined study using LA-ICP-MS U-Pb dating, Hf isotopes, trace elements and the Ti-in-zircon geo-thermometer was carried out on zircons from the metamorphosed basic-ultrabasic rocks in the meta-morphic basement of the Cathaysia Block, southwestern Zhejiang Province. The formation and meta-morphic ages of the rocks from the metamorphic basement of the Cathaysia Block were determined based on zircon U-Pb geochronology. The age for the magmatic crystalline zircons from the protolith is about 1.85 Ga. The εHf(t) values of the older zircons were from ?7 to ?3, with two-stage model Hf ages (TDM2LC) of about 2.9 to 3.4 Ga, indicating that the source material was derived from anatexis and recy-cling of the Archean crust. The newly formed metamorphic zircons yielded U-Pb ages of 260―230 Ma. The metamorphic temperature calculated using the Ti-in-zircon geothermometer ranged from 610 to 720℃, consistent with the results from petrographic observations, indicating that the Cathaysia Block experienced an amphibolite facies metamorphism during the Indosinian. Results from this study pro-vided an important timeframe for the tectonic evolution in South China and the Southeast Asia during the Late Permian and Early Triassic times. | XIANG Hua ZHANG Li ZHOU HanWen ZHONG ZengQiu ZENG Wen LIU Rui JIN Song | 2008 | Science China Earth Sciences2008，51，6： | 24 |
| 2 | Simultaneous determination of ten taste and odor compounds in drinking water by solid-phase microextraction combined with gas chromatography-mass spectrometry显示文摘Taste and odor(T&O)problems in drinking water frequently occur because of many compounds present in the water,of which trans-1,10-dimethyl-trans-9-decalol(geosmin)and 2-methylisoborneol(MIB)are well-known.In this study,a fast and efective method was established for simultaneous determination of 10 T&O compounds,including geosmin,MIB,2,4,6-trichloroanisole(TCA),2-methylbenzofuran,2-isopropyl-3-methoxypyrazine(IPMP),2-isobutyl-3-methoxypyrazine(IBMP),cis-3-hexenyl acetate,trans,trans-2,4-heptadienal,trans,cis-2,6-nonadienal,and trans-2-decenal in water samples by headspace solid-phase microextraction(SPME)coupled with gas chromatography-mass spectrometry.An orthogonal array experimental design was used to optimize the efects of SPME fiber,extraction temperature,stirring rate,NaCl content,extraction time,and desorption time.The limits of detection ranged from 0.1 to 73 ng/L were lower than or close to the odor threshold concentrations(OTCs).All the 10 T&O compounds were detected in the 14 water samples including surface water,treatment process water and tap water,taken from a waterworks in Lianyungang City,China.MIB and geosmin were detected in most samples at low concentration.Six T&O compounds(IPMP,IBMP,trans,cis-2,6-nonadienal,2-methylbenzofuran,trans-2-decenal,and TCA)were efectively decreased in water treatment process(sedimentation and filtration)that is diferent from cis-3-hexenyl acetate,MIB and geosmin.It is noted that the TCA concentrations at 15.9–122.3 ng/L and the trans,cis-2,6-nonadienal concentrations at 79.9–190.1 ng/L were over 10 times higher than their OTCs in tap water.The variation of the analytes in the all water samples,especially distribution system indicated that distribution system cannot be ignored as a T&O compounds source. | Xichao Chen Qian Luo Shengguang Yuan Zi Wei Hanwen Song Donghong Wang Zijian Wang | 2013 | Journal of Environmental Sciences2013，25，11： | 21 |
| 3 | Caledonian reworking of Paleoproterozoic basement in the Cathaysia Block: Constraints from zircon U-Pb dating, Hf isotopes and trace elements显示文摘A combined study of zircon U-Pb dating, Hf isotopes and trace elements has been carried out for granodioritic neosomes of migmatites from the Tianjingping area in northwestern Fujian Province. Zircons are characterized by zoning, higher Th/U ratios (mostly ≥0.1), HREE enrichment, and positive Ce and negative Eu anomalies, and show features similar to magmatic or anatectic zircons. Apparent 206Pb/238U ages for the zircons are 447±2 Ma (95% conf., MSWD = 0.88), corresponding to a Caledonian event. εHf(t) values are ?13.3 to ?9.7, indicating a crustal source. Two-stage Hf model ages are 1.7 to 1.9 Ga, suggesting that protolith of the migmates was probably formed in the Paleoproterozoic. The granodioritic neosomes have the characteristics of peraluminous calc-alkaline granite, and their REE patterns and trace elements spidergrams show features of middle to upper crustal rocks. Together with previous studies, we conclude that the protolith of the Cathaysia basement in the Tianjingping area was likely formed in the middle-late Paleoproterozoic and experienced partial melting during the Caledonian period. The recognition of Caledonian reworking of the Paleoproterozoic basement in the Cathaysia Block provides a new insight into the tectonic evolution of the Cathaysia Block in the Caledonian pe- riod and the interaction between the Cathaysia Block and the Yangtze Block. | ZENG Wen ZHANG Li ZHOU HanWen ZHONG ZengQiu XIANG Hua LIU Rui JIN Song LU XinQian LI ChunZhong | 2008 | Chinese Science Bulletin2008，53，6： | 21 |
| 4 | Self-contained eigenvector algorithm applied to the identification of aerodynamic derivatives of bridge model显示文摘On one hand, when the bridge stays in a windy environment, the aerodynamic power would reduce it to act as a non-classic system. Consequently, the transposition of the system’s right eigenmatrix will not equal its left eigenmatrix any longer. On the other hand, eigenmatrix plays an important role in model identification, which is the basis of the identification of aerodynamic derivatives. In this study, we follow Scanlan’s simple bridge model and utilize the information provided by the left and right eigenmatrixes to structure a self-contained eigenvector algorithm in the frequency domain. For the purpose of fitting more accurate transfer function, the study adopts the combined sine-wave stimulation method in the numerical simulation. And from the simulation results, we can conclude that the derivatives identified by the self-contained eigenvector algorithm are more dependable. | ZHANG XiaoXu CHEN LiFen SONG HanWen | 2011 | Science China(Technological Sciences)2011，54，5： | 3 |
| 5 | Efficient coding schemes with power allocation using space-time-frequency spreading显示文摘An efficient space-time-frequency (ST F) coding strategy for multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) systems is presented for high bit rate data transmission over frequency selective fading channels. The proposed scheme is a new approach to space-time-frequency coded OFDM (COFDM) that combines OFDM with space-time coding, linear precoding and adaptive power allocation to provide higher quality of transmission in terms of the bit error rate performance and power efficiency. In addition to exploiting the maximum diversity gain in frequency, time and space, the proposed scheme enjoys high coding advantages and low-complexity decoding. The significant performance improvement of our design is confirmed by corroborating numerical simulations. | Jiang Haining Luo Hanwen Tian Jifeng Song Wentao Liu Xingzhao | 2006 | Journal of Systems Engineering and Electronics2006，17，2： | 1 |
| 6 | A frequency-domain method for solving linear time delay systems with constant coefficients显示文摘In an active control system, time delay will occur due to processes such as signal acquisition and transmission, calculation,and actuation. Time delay systems are usually described by delay differential equations(DDEs). Since it is hard to obtain an analytical solution to a DDE, numerical solution is of necessity. This paper presents a frequency-domain method that uses a truncated transfer function to solve a class of DDEs. The theoretical transfer function is the sum of infinite items expressed in terms of poles and residues. The basic idea is to select the dominant poles and residues to truncate the transfer function,thus ensuring the validity of the solution while improving the efficiency of calculation. Meanwhile, the guideline of selecting these poles and residues is provided. Numerical simulations of both stable and unstable delayed systems are given to verify the proposed method, and the results are presented and analysed in detail. | Mengshi Jin Wei Chen Hanwen Song Jian Xu | 2018 | Acta Mechanica Sinica2018，34，4： | 1 |

| 10 | Design and Implementation of Single Chip WCDMA High Speed Channel Decoder显示文摘A memory and driving clock efficient design scheme to achieve WCDMA high-speed channel decoder on a single XILINX’ XVC1000E FPGA chip is presented. Using a modified MAP algorithm, say parallel Sliding Window logarithmic Maximum A Posterior (PSW-log-MAP), the on-chip turbo decoder can decode an information bit by only an average of two clocks per iteration. On the other hand, a high-parallel pipeline Viterbi algorithm is adopted to realize the 256-state convolutional code decoding. The final decoder with an 8×chip-clock (30 72MHz) driving can concurrently process a data rate up to 2 5Mbps of turbo coded sequences and a data rate over 400kbps of convolutional codes. There is no extern memory needed. Test results show that the decoding performance is only 0 2~0 3dB or less lost comparing to float simulation. | 徐友云 Li Zongwang Ruan Ming Luo Hanwen Song Wentao | 2001 | High Technology Letters2001，7，2： | 0 |
| 11 | Design and Implementation of a Novel Algorithm for Iterative Decoding of Product Codes显示文摘A novel product code iterative decoding algorithm and its high speed implementation scheme are proposed in this paper. Based on partial combination of selected columns of check matrix, the reduced-complexity syndrome decoding method is proposed to decode sub-codes of product code and deliver soft output information. So iterative decoding of product codes is possible. The fast sorting algorithm and a look-up method are proposed for high speed implementation of this algorithm. Compared to the conventional weighing iterative algorithm, the proposed algorithm has lower complexity while offering better performance, which is demonstrated by simulations and implementation analysis. The implementation scheme and verilog HDL simulation show that it is feasible to achieve high speed decoding with the proposed algorithm. | 李宗旺 Song Wentao Luo Hanwen | 2003 | High Technology Letters2003，9，1： | 0 |
| 12 | Interface challenges and optimization strategies for aqueous zinc-ion batteries显示文摘Aqueous zinc-ion batteries have advantages over lithium-ion batteries,such as low cost,and good safety.However,their development is currently facing several challenges.One of the main critical challenges is their poor electrode–electrolyte interface.Addressing this requires understanding the physics and chemistry at the electrode–electrolyte interface,including the cathode-electrolyte interface and anodeelectrolyte interface.This review first identifies and analyses the interfacial challenges of aqueous zincion batteries.Then,it discusses the design strategies for addressing the defined interfacial issues from the perspectives of electrolyte optimization,electrode modification,and separator improvement.Finally,it provides corrective recommendations and strategies for the rational design of electrode–electrolyte interface in aqueous zinc-ion batteries towards their high-performance and reliable energy storage. | Hanwen Liu Qianqin Zhou Qingbing Xia Yaojie Lei Xiang Long Huang Mike Tebyetekerwa Xiu Song Zhao | 2023 | Journal of Energy Chemistry2023，，2： | 0 |
| 13 | A Novel Concatenated Chaotic Communication System显示文摘A strategy for a novel concatenated chaotic communication system is presented. The transmitter system comprises chaotic turbo encoder and logistic CSK block in a serially concatenated form. Chaotic turbo code is capable of reducing bit error rate (BER) of the chaotic system in the AWGN channel. Through the chaotic turbo encoder, the coded sequence, which has quasi-chaotic properties, will be transmitted into the logistic CSK block. Having a very sensitive dependence on initial conditions of the map, the logistic CSK block can also be taken as the chaotic authentication method. The receiver, which has logistic demodulation block and chaotic decoder, is a linear asymptotic approximation to the inverse of the transmitter system. A chaotic iterative soft-decision decoding algorithm is also developed based on conventional maximum A posteriori decoding algorithm. At last, a two-step authentication method of this chaotic system is also presented. | Zhou Xiaolin, Song Wentao, Wu Dijia, Liu Jianbo & Luo Hanwen Department of Electronic Engineering, Shanghai Jiaotong University, Shanghai 200030, P.R.China(Received August 7, 2001) | 2002 | Journal of Systems Engineering and Electronics2002，13，2： | 0 |
| 14 | Time-delay identification for linear controlled systems显示文摘A new approach for time-delay identifcation is proposed in linear controlled systems.The delay is derived from the control loop in the system.The frequency-response function of the system is presented in terms of the impedance matrix.It is proved that the inverse form of the function may be expressed in the harmonic function,which is used to ft those data from the experiment.As an example,an isolator with the delayed feedback control is schemed to acquire such data.Using least square algorithm yields that the identifed delay can reach any required accuracy. | Yiqiang Sun Hanwen Song Jian Xu | 2013 | Theoretical & Applied Mechanics Letters2013，3，6： | 0 |
| 15 | Magnesium promotes vascularization and osseointegration in diabetic states显示文摘Diabetes has long been considered a risk factor in implant therapy and impaired wound healing in soft and hard oral tissues.Magnesium has been proved to promote bone healing under normal conditions.Here,we elucidate the mechanism by which Mg~(2+)promotes angiogenesis and osseointegration in diabetic status.We generated a diabetic mice model and demonstrated thealveolar bone healing was compromised,with significantly decreased angiogenesis.We then developed Mg-coating implants with hydrothermal synthesis.These implants successfully improved the vascularization and osseointegration in diabetic status.Mechanically,Mg~(2+)promoted the degradation of Kelch-like ECH-associated protein 1 (Keap1) and the nucleation of nuclear factor erythroid 2-related factor 2 (Nrf2) by up-regulating the expression of sestrin 2 (SESN2) in endothelial cells,thus reducing theelevated levels of oxidative stress in mitochondria and relieving endothelial cell dysfunction under hyperglycemia.Altogether,our data suggested that Mg~(2+)promoted angiogenesis and osseointegration in diabetic mice by regulating endothelial mitochondria metabolism. | Linfeng Liu Feiyu Wang Wei Song Danting Zhang Weimin Lin Qi Yin Qian Wang Hanwen Li Quan Yuan Shiwen Zhang | 2024 | International Journal of Oral Science2024，16，1： | 0 |
| 16 | A channel- and QoS-adaptive turbo coded modulation architecture for mobile multimedia communication显示文摘This paper proposed a cross-layer dual adaptive coded modulation architecture using turbo codes formobile multimedia communication,which simultaneously adapted to both the varying channel characteris-tics and the quality of service(QoS)of various mobile multimedia services to increase the average systemthroughput substantially.A pragmatic channel-adaptive turbo coded modulation scheme,which comeswithin 2.5dB of the Shannon limit,was optimally designed,and then a QoS-adaptive scheme was super-imposed to build the dual adaptive architecture.Simulation results show that the novel dual adaption re-duces the difference with the fading channel capacity to 2dB when assuming different services occur in e-qual probability and the service duration follows the exponential distribution. | 左健存 Song Wentao Luo Hanwen Xu Youyun | 2009 | High Technology Letters2009，15，1： | 0 |
| 17 | The Palestine-Israel Issue in the Post-Covid-19 Era—From the Perspective of Neocolonialism显示文摘Strictly speaking,the economic relationship between Israel and Palestine cannot be simply defined as neocolonial occupation,but are closely related to neo-colonialism,in terms of control,dependence,resistance,exploitation,monopoly and interference.Therefore,neo-colonialism can be used as a perspective to analyse the economic relations between Palestine and Israel.Although the two sides have always been in a relatively hostile relationship,due to years of stalemate and Israeli economic control,the two sides have formed an interdependent economic relationship,where Israel has a relatively dominant position in the relations,thanks to its long-term occupation and control over the land,while the Palestinian economy will continue to remain highly dependent on Israel,despite its official efforts to achieve economic disengagement.In this case,Israel is reluctant to sever the relationship,and Palestine is unable to decouple from the Israeli economy.The outbreak of the Covid-19 pandemic has made the prospects for Palestinian-Israeli peace talks even bleaker.As the peace process continues to stall,a settlement to resolve the dispute between Israel and the Palestinians remains highly unlikely. | Meng Shu Yun Song Hanwen Zhang | 2021 | Asian Journal of Middle Eastern and Islamic Studies2021，15，4： | 0 |
| 18 | Novel time-frequency differential space-time modulation for multi-antenna OFDM systems显示文摘Differential space-time (DST) modulation has been proposed recently for multiple-antenna systems over Rayleigh fading channels, where neither the transmitter nor the receiver knows the fading coefficients. Among existing schemes, differential modulation is always performed in the time domain and suffers performance degradations in frequency-selective fading channels. In order to combat the fast time and frequency-selective fading, a novel time-frequency differential space-time (TF-DST) modulation scheme, which adopts differential modulation in both time and frequency domains, is proposed for multi-antenna orthogonal frequency division multiplexing (OFDM) system. A corresponding sub-optimal yet low-complexity non-coherent detection approach is also proposed. Simulation results demonstrate that the proposed system is robust for time and frequency-selective Rayleigh fading channels. | Tian Jifeng Jiang Haining Song Wentao Luo Hanwen Xu Youyun | 2006 | Journal of Systems Engineering and Electronics2006，17，1： | 0 |
