| 1 | Molecular dynamics study on the relationships of modeling,structural and energy properties with sensitivity for RDX-based PBXs显示文摘In this paper,a primary model is established for MD(molecular dynamics) simulation for the PBXs(polymer-bonded explosives) with RDX(cyclotrimethylene trinitramine) as base explosive and PS as polymer binder.A series of results from the MD simulation are compared between two PBX models,which are represented by PBX1 and PBX2,respectively,including one PS molecular chain having 46 repeating units and two PS molecular chains with each having 23 repeating units.It has been found that their structural,interaction energy and mechanical properties are basically consistent between the two models.A systematic MD study for the PBX2 is performed under NPT conditions at five different temperatures,i.e.,195 K,245 K,295 K,345 K,and 395 K.We have found that with the temperature increase,the maximum bond length(L max) of RDX N N trigger bond increases,and the interaction energy(E N-N) between two N atoms of the N-N trigger bond and the cohesive energy density(CED) decrease.These phenomena agree with the experimental fact that the PBX becomes more sensitive as the temperature increases.Therefore,we propose to use the maximum bond length L max of the trigger bond of the easily decomposed and exploded component and the interaction energy E N-N of the two relevant atoms as theoretical criteria to judge or predict the relative degree of heat and impact sensitivity for the energetic composites such as PBXs and solid propellants. | XIAO JiJun ZHAO Li ZHU Wei CHEN Jun JI GuangFu ZHAO Feng WU Qiang XIAO HeMing | 2012 | Science China Chemistry2012，55，12： | 12 |
| 2 | Speech endpoint detection in low-SNRs environment based on perception spectrogram structure boundary parameter显示文摘The Perception Spectrogram Structure Boundary(PSSB)parameter is proposed for speech endpoint detection as a preprocess of speech or speaker recognition.At first a hearing perception speech enhancement is carried out.Then the two-dimensional enhancement is performed upon the sound spectrogram according to the difference between the determinacy distribution characteristic of speech and the random distribution characteristic of noise.Finally a decision for endpoint was made by the PSSB parameter.Experimental results show that,in a low SNR environment from-10 dB to 10 dB,the algorithm proposed in this paper may achieve higher accuracy than the extant endpoint detection algorithms.The detection accuracy of 75.2%can be reached even in the extremely low SNR at-10 dB.Therefore it is suitable for speech endpoint detection in low-SNRs environment. | WU Di ZHAO Heming HUANG Chengwei XIAO Zhongzhe ZHANG Xiaojun XU Yishen TAO Zhi | 2014 | Chinese Journal of Acoustics2014，33，4： | 8 |
| 3 | PDMS microchannel fabrication technique based on microwire-molding显示文摘Micro-flow channel is basic functional component of microfluidic chip,and every step-forward of its construction technique has been receiving concern all over the world.This article presents a not-complicated but flexible method for fabrication of micro-flow channels.This method mainly utilizes the conventional molding capability of polydimethylsiloxane(PDMS) and widespread commercial microwires as templates.We have fabricated out some conventional types of microchannels with different topological shapes,as examples for the demonstration of this flexible fabrication route which was not dependent on the stringent demands of photolithographical or microelectromechanical system(MEMS) techniques.The smooth surface,high-intensity,and high flexibility of the wires made it possible to create many types of topological structures of the two-dimensional or three-dimensional microchannel or channel array.The geometric shape of the cross-section of thus forming microchannel in PDMS was the negative of that of embedded-in microwire,in high-fidelity if suitable measures were taken.More-over,such a microchannel fabrication process can easily integrate the conductivity and low resistivity of the metal wire to create micro-flow devices that are suitable for the electromagnetic control of liquid or the temperature regulation in the microchannel.Furthermore some preliminary optical analysis was provided for the observation of thus forming rounded microchannel.Based on this molding strategy,we even made some prototypes for functional microflow application,such as microsolenoids chip and temperature control gadgets.And an experiment of forming a droplet in the cross channel further confirmed the feasibility and applicability of this flexible microchannel forming technique. | JIA YueFei JIANG JiaHuan MA XiaoDong LI Yuan HUANG HeMing CAI KunBao CAI ShaoXi WU YunPeng | 2008 | Chinese Science Bulletin2008，53，24： | 5 |
| 4 | Construction of [Cu_nI_n]-based coordination polymers via flexible benzimidazolyl-based ligands显示文摘Four new [CunIn]-based coordination polymers, [{Cu4(μ3-I)4(mbbm)2}·2DMF]n (1), [(CuI)2(mbbm)2]n (2), [{Cu2(μ-I)2-(ebbm)2}·2MeCN]n (3), and [Cu2(μ-I)2(prbbm)2]n (4), were prepared from solvothermal reactions of CuI with three flexible ligands [(bzim)(CH2)n(bzim)] (bzim = benzimidazole; n = 1, mbbm; n = 2, ebbm; n = 3, prbbm). These compounds were characterized by elemental analysis, IR and X-ray crystallography. 1 consists of cubanelike [Cu4(μ3-I)4] fragments that link the neighboring ones via mbbm bridges to form a 1D ladder-type chain. 2 contains mononuclear [CuI] fragments that are bridged by mbbm ligands to yield a 1D zigzag chain. 3 or 4 contains a [Cu2(μ-I)2] dimeric fragment, which works as a four-connecting node to link its four equivalent ones to form a 2D (4,4) network (3) or acts as a two-connecting node to connect its two equivalent ones via two pairs of prbbm bridges to form a 1D double chain (4). The photoluminescent properties of 1-4 in the solid state at ambient temperature were investigated. | LI LingLing, REN ZhiGang, Lü Xue, WANG HeMing, CHANG YuJie, LI HongXi, WU Bing & LANG JianPing College of Chemistry, Chemical Engineering and Materials Science, Suzhou University, Suzhou 215123, China | 2010 | Science China Chemistry2010，53，10： | 1 |

| 7 | Conversion from whispered speech to normal speech using the extended bilinear transformation method显示文摘A method of conversion from whispered speech to normal speech using the extended bilinear transformation was proposed.On account of the different deviation degrees of the whisper's formants in different frequency bands,the spectrum of the whispered speech will be processed in the separate partitions of this paper.On the basis of this spectrum,we will establish a conversion function able to usefully convert whispered speech to normal speech.Because of the whisper's non-linear offset in relation to normal speech,this paper introduces an expansion factor in the bilinear transform function making it correspond more closely to the actual conversion demands of whispered speech to normal speech.The introduction of this factor takes the non-linear move of the spectrum and the compression of the formant bandwidth into consideration,thus effectively reducing the spectrum distortion distance in the conversion.The experiment results show that the conversion presented in this paper effectively improves both the sound quality and the intelligibility of whispered speech. | TAO Zhi ZHAO Heming TAN Xuedan GU Jihua ZHANG Xiaojun WU Di | 2013 | Chinese Journal of Acoustics2013，32，4： | 1 |

| 13 | Two-photon 3D printed spring-based Fabry-Pérot cavity resonator for acoustic wave detection and imaging显示文摘Optical fiber microresonators have attracted considerable interest for acoustic detection because of their compact size and high optical quality.Here,we have proposed,designed,and fabricated a spring-based Fabry-Pérot cavity microresonator for highly sensitive acoustic detection.We observed two resonator vibration modes:one relating to the spring vibration state and the other determined by the point-clamped circular plate vibration mode.We found that the vibration modes can be coupled and optimized by changing the structure size.The proposed resonator is directly 3D printed on an optical fiber tip through two-photon polymerization and is used for acoustic detection and imaging.The experiments show that the device exhibits a high sensitivity and low noise equivalent acoustic signal level of 2.39 mPa∕Hz^(1∕2)at 75 kHz that can detect weak acoustic waves,which can be used for underwater object imaging.The results demonstrate that the proposed work has great potential in acoustic detection and biomedical imaging applications. | HEMING WEI ZHANGLI WU KEXUAN SUN HAIYAN ZHANG CHEN WANG KEMIN WANG TIAN YANG FUFEI PANG XIAOBEI ZHANG TINGYUN WANG SRIDHAR KRISHNASWAMY | 2023 | Photonics Research2023，11，5： | 0 |
| 14 | A review of recent advances(2018–2021)on tropical cyclone intensity change from operational perspectives,part 1:Dynamical model guidance显示文摘This review summarizes the rapporteur report on tropical cyclone(TC)intensity change from the operational perspective,as presented to the 10th International Workshop on TCs(IWTC-10)held in Bali,Indonesia,from Dec.5–9,2022.The accuracy of TC intensity forecasts issued by operational forecast centers depends on three aspects:real-time observations,TC dynamical model forecast guidance,and techniques and methods used by forecasters.The rapporteur report covers the progress made over the past four years(2018–2021)in all three aspects.This review focuses on the progress of dynamical model forecast guidance.The companion paper(Part II)summarizes the advance from operational centers.The dynamical model forecast guidance continues to be the main factor leading to the improvement of operational TC intensity forecasts.Here,we describe recent advances and developments of major operational regional dynamical TC models and their intensity forecast performance,including HWRF,HMON,COAMPS-TC,Met Office Regional Model,CMA-TYM,and newly developed HAFS.The performance of global dynamical models,including NOAA's GFS,Met Office Global Model(MOGM),JMA's GSM,and IFS(ECMWF),has also been improved in recent years due to their increased horizontal and vertical resolution as well as improved data assimilation systems.Recent challenging cases of rapid intensification are presented and discussed. | Zhan Zhang Weiguo Wang James D.Doyle Jonathan Moskaitis William A.Komaromi Julian Heming Linus Magnusson John P.Cangialosi Levi Cowan Michael Brennan Suhong Ma Ananda Kumar Das Hosomi Takuya Peter Clegg Thomas Birchard John A.Knaff John Kaplan Mrutyunjay Mohapatra Monica Sharma Ikegami Masaaki Liguang Wu Eric Blake | 2023 | Tropical Cyclone Research and Review2023，12，1： | 0 |
| 15 | A review of recent advances(2018–2021)on tropical cyclone intensity change from operational perspectives,part 2:Forecasts by operational centers显示文摘This paper summarizes the progress and activities of tropical cyclone(TC)operational forecast centers during the last four years(2018–2021).It is part II of the review on TC intensity change from the operational perspective in the rapporteur report presented to the 10th International Workshop on TCs(IWTC)held in Bali,Indonesia,from Dec.5–9,2022.Part I of the review has focused on the progress of dynamical model forecast guidance.This part discusses the performance of TC intensity and rapid intensification forecasts from several operational centers.It is shown that the TC intensity forecast errors have continued to decrease since the 9th IWTC held in 2018.In particular,the improvement of rapid intensification forecasts has accelerated,compared with years before 2018.Consensus models,operational procedures,tools and techniques,as well as recent challenging cases from 2018 to 2021 identified by operational forecast centers are described.Research needs and recommendations are also discussed.©2023 The Shanghai Typhoon Institute of China Meteorological Administration.Publishing services by Elsevier B.V.on behalf of KeAi Communication Co.Ltd.This is an open access article under the CC BY-NC-ND license(http://gffzzeb6f7f563f66445dhc65fpuxxpqqf6f5b.ffgz.tsg.suse.edu.cn/licenses/by-nc-nd/4.0/). | Weiguo Wang Zhan Zhang John P.Cangialosi Michael Brennan Levi Cowan Peter Clegg Hosomi Takuya Ikegami Masaaki Ananda Kumar Das Mrutyunjay Mohapatra Monica Sharma John A.Knaff John Kaplan Thomas Birchard James D.Doyle Julian Heming Jonathan Moskaitis Suhong Ma Charles Sampson Liguang Wu Eric Blake | 2023 | Tropical Cyclone Research and Review2023，12，1： | 0 |
| 16 | Phenolic rigid organic filler/isotactic polypropylene composites. Ⅲ. Impact resistance property显示文摘A novel phenolic rigid organic filler(KT)was used to modify isotactic polypropylene(iPP).The influence of KT particles on the impact resistance property of PP/KT specimens(with similar interparticles distance,1.8μm)was studied by notched izod impact tests.It was found that the brittle-ductile transition(BDT)of the PP/KT microcomposites took place at the filler content of about 4%,and the impact strength attains the maximum at 5%(with filler particles size of 1.5μm),which is about 2.5 times that of unfilled iPP specimens.The impact fracture morphology was investigated by scanning electron micro-scopy(SEM).For the PP/KT specimens and the high-density polyethylene/KT(HDPE/KT)specimens in ductile fracture mode,many microfibers could be found on the whole impact fracture surface.It was the filler particles that induced the plastic deformation of interparticles ligament and hence improved the capability of iPP matrix on absorbing impact energy dramatically.The determinants on the BDT were further discussed on the basis of stress concentration and debonding resistance.It can be con-cluded that aside from the interparticle distance,the filler particles size also plays an important role in semicrystal-line polymer toughening. | Heming LIN Dongming QI Jian HAN Zhiqi CAI Minghua WU | 2009 | Frontiers of Chemical Science and Engineering2009，3，2： | 0 |

| 18 | Phenolic rigid organic filler/isotactic polypropylene composites.I.Preparation显示文摘A novel phenolic rigid organic filler(KT)was melt-mixed with an isotactic polypropylene(iPP)to prepare a series of PP/KT composites,with or without maleic anhydride grafted polypropylene(MAPP)as compatilizer.The evolution of filler morphology during melt-mixing and melt-pressure processes was monitored by scanning electron microscope(SEM)and polarized optical microscope(POM).The influences of shear force,pressure time,filler content and MAPP concentration on the final filler dispersion were studied.We found that this rigid organic filler readily melted and dispersed homogenously into the iPP matrix through a fission-fusion process during the melt-mixing process.Thus a balanced dispersion,which was closely related to shear force and MAPP concentration,can be achieved.During the meltpressure process,parts of the filler particles combined gradually through a coalescence process.However,the incorporation of MAPP can effectively inhibit the tendency to coalesce and refine the filler particles sizes into nanoscale.Thus,a series of PP/KT composites with controllable filler particles size and narrow size distribution can be obtained just by adjusting process conditions and MAPP concentration.In addition,due to the in-situ formation mechanism,the filler phase possessed a typical solid true-spherical shape. | Dongming QI Lei YANG Minghua WU Heming LIN Kohhei NITTA | 2008 | Frontiers of Chemical Science and Engineering2008，2，3： | 0 |
| 19 | Research advances in peptide-drug conjugates显示文摘Peptide-drug conjugates(PDCs)are drug delivery systems consisting of a drug covalently coupled to a multifunctional peptide via a cleavable linker.As an emerging prodrug strategy,PDCs not only preserve the function and bioactivity of the peptides but also release the drugs responsively with the cleavable property of the linkers.Given the ability to significantly improve the circulation stability and targeting of drugs in vivo and reduce the toxic side effects of drugs,PDCs have already been extensively applied in drug delivery.Herein,we review the types and mechanisms of peptides,linkers and drugs used to construct PDCs,and summarize the clinical applications and challenges of PDC drugs. | Liming Gong Heming Zhao Yanhong Liu Hao Wu Chao Liu Shuangyan Chang Liqing Chen Mingji Jin Qiming Wang Zhonggao Gao Wei Huang | 2023 | Acta Pharmaceutica Sinica B2023，13，9： | 0 |
