| 2 | An acid-triggered porphyrin-based block copolymer for enhanced photodynamic antibacterial efficacy显示文摘Bacterial infection, especially multidrug-resistant(MDR) bacterial infection has threatened public health drastically. Here, we fabricate an 'acid-triggered' nanoplatform for enhanced photodynamic antibacterial activity by reducing the aggregation of photosensitizers(PSs) in bacterial acidic microenvironment. Specifically, a functional amphiphilic block copolymer was first synthesized by using a pH-sensitive monomer, 2-(diisopropylamino) ethyl methacrylate(DPA) and porphyrin-based methacrylate(TPPC6MA) with poly(oligo(ethylene glycol) methyl ether methacrylate)(POEGMA) as the macromolecular chain transfer agent, and POEGMA-b-[PDPA-co-PTPPC6MA] block copolymer was further self-assembled into spherical nanoparticles(PDPA-TPP). PDPA-TPP nanoparticles possess an effective electrostatic adherence to negatively charged bacterial cell membrane, since they could rapidly achieve positive charge in acidic bacterial media. Meanwhile, the acid-triggered dissociation of PDPA-TPP nanoparticles could reduce the aggregation caused quenching(ACQ) of the photosensitizers, leading to around 5 folds increase of the singlet oxygen(1O2) quantum yield. In vitro results demonstrated that the 'acid-triggered' PDPA-TPP nanoparticles could kill most of MDR S. aureus(Gram-positive) and MDR E. coli(Gram-negative) by enhanced photodynamic therapy, and they could resist wound infection and accelerate wound healing effectively in vivo. Furthermore, PDPA-TPP nanoparticles could well disperse the biofilm and almost kill all the biofilm-containing bacteria. Thus, by making use of the bacterial acidic microenvironment, this 'acid-triggered' nanoplatform in situ will open a new path to solve the aggregation of photosensitizers for combating broad-spectrum drug-resistant bacterial infection. | Fan Yu Chao Chen Guoliang Yang Zhengtong Ren Hongliang Cao Liangshun Zhang Weian Zhang | 2021 | Science China Chemistry2021，64，3： | 2 |
| 3 | Variations in the biomass of Eucalyptus plantations at a regional scale in Southern China显示文摘We quantified deviations in regional forest biomass from simple extrapolation of plot data by the biomass expansion factor method(BEF) versus estimates obtained from a local biomass model,based on large-scale empirical field inventory sampling data.The sources and relative contributions of deviations between the two models were analyzed by the boosted regression trees method.Relative to the local model,BEF overestimated accumulative biomass by 22.12%.The predominant sources of the total deviation (70.94%) were stand-structure variables.Stand age and diameter at breast height are the major factors.Compared with biotic variables,abiotic variables had a smaller overall contribution (29.06%),with elevation and soil depth being the most important among the examined abiotic factors.Large deviations in regional forest biomass and carbon stock estimates are likely to be obtained with BEF relative to estimates based on local data.To minimize deviations,stand age and elevation should be included in regional forest-biomass estimation. | Quanyi Qiu Guoliang Yun Shudi Zuo Jing Yan Lizhong Hua Yin Ren Jianfeng Tang Yaying Li Qi Chen | 2018 | Journal of Forestry Research2018，29，5： | 2 |
| 4 | Fixing, preventing, and recovering from concurrency bugs显示文摘Concurrency bugs are becoming widespread with the emerging ubiquity of multicore processors and multithreaded software. They manifest during production runs and lead to severe losses. Many effective concurrency-bug detection tools have been built. However, the dependability of multi-threaded software does not improve until these bugs are handled statically or dynamically. This article discusses our recent progresses on fixing, preventing, and recovering from concurrency bugs. | DENG DongDong JIN GuoLiang de KRUIJF Marc LI Ang LIBLIT Ben LU Shan QI ShanXiang REN JingLei SANKARALINGAM Karthikeyan SONG LinHai WU YongWei ZHANG MingXing ZHANG Wei ZHENG WeiMin | 2015 | Science China(Information Sciences)2015，58，5： | 2 |

| 9 | Effects of baffles on separation of aqueous ethanol solution with hollow fibers显示文摘The effects of baffles on the operation and mass-transfer characteristics in novel hollowfiber membrane contactor used in distillation were investi-gated.Hollowfiber membranes,coated with a 7μm polydimethyl-siloxane,were operated as structural packing in the separation of ethanol-water solutions.The parallelflow mode was chosen for separation due to the stronger driving force of the concentration difference,in which liquidflows through the lumens of thefibers and vaporflows countercurrent-wise outside thefibers.Two baffles were installed on the shell side of the membrane contactors to enhance separation,which had a round shape with a semi-lunar hole.The results show that both baffled and unbaffled membrane contactors gave better,more produc-tive separations than traditional packing in distillation,such as the excellent Sulzer Gauze BX structured packing.The baffled membrane contactors performed better than unbaffled ones,especially at high vapor velocities.The minimal HTU of membrane contactor with baffles could reach as low as 4.5 cm,and almost all the contactors could work well above the limit whereflooding normally occurs in conventional cases.Theoretical analysis predicted that baffles helped membrane module to obtain a higher mass-transfer coefficient and a smaller mass-transfer resistance.Finally,theoretical mass-transfer coefficient and experi-mental value were compared as well as the contribution of each individual mass-transfer coefficients among liquid,gas and membrane. | Zhihong YANG Guoliang ZHANG Lan LIN Danping REN Qin MENG Hongzi ZHANG | 2009 | Frontiers of Chemical Science and Engineering2009，3，1： | 0 |

| 11 | Does Success Breed Success?A Study on the Correlation between Impact Factor and Quantity in Chinese Academic Journals显示文摘Purpose:This paper studies the relationship between the impact factor(IF)and the number of journal papers in Chinese publishing system.Design/methodology/approach:The method proposed by Huang(2016)is used whereas to analysis the data of Chinese journals in this study.Findings:Based on the analysis,we find the following.(1)The average impact factor(AIF)of journals in all disciplines maintained a growth trend from 2007 to 2017.Whether before or after removing outlier journals that may garner publication fees,the IF and its growth rate for most social sciences disciplines are larger than those of most natural sciences disciplines,and the number of journal papers on social sciences disciplines decreased while that of natural sciences disciplines increased from 2007 to 2017.(2)The removal of outlier journals has a greater impact on the relationship between the IF and the number of journal papers in some disciplines such as Geosciences because there may be journals that publish many papers to garner publication fees.(3)The success-breeds-success(SBS)principle is applicable in Chinese journals on natural sciences disciplines but not in Chinese journals on social sciences disciplines,and the relationship is the reverse of the SBS principle in Economics and Education&Educational Research.(4)Based on interviews and surveys,the difference in the relationship between the IF and the number of journal papers for Chinese natural sciences disciplines and Chinese social sciences disciplines may be due to the influence of the international publishing system.Chinese natural sciences journals are losing their academic power while Chinese social sciences journals that are less influenced by the international publishing system are in fierce competition.Research limitation:More implications could be found if long-term tracking and comparing the international publishing system with Chinese publishing system are taken.Practical implications:It is suggested that researchers from different countries study natural science and social sciences journals in their languages and observe the influence of the international publishing system.Originality/value:This paper presents an overview of the relationship between IF and the number of journal papers in Chinese publishing system from 2007 to 2017,provides insights into the relationship in different disciplines in Chinese publishing system,and points out the similarities and differences between Chinese publishing system and international publishing system. | Kun Chen Xiantong Ren Guoliang Yang Ailifeire Abudouguli | 2021 | Journal of Data and Information Science2021，6，4： | 0 |
| 12 | A review of DEA methods to identify and measure congestion显示文摘Congestion is an economic phenomenon of overinvestment that occurs when excessive inputs decrease the maximally possible outputs.Although decision-makers are unlikely to decrease outputs by increasing inputs,congestion is widespread in reality.Identifying and measuring congestion can help decision-makers detect the problem of overinvestment.This paper reviews the development of the concept of congestion in the framework of data envelopment analysis(DEA),which is a widely accepted method for identifying and measuring congestion.In this paper,six main congestion identification and measurement methods are analysed through several numerical examples.We investigate the ideas of these methods,the contributions compared with the previous methods,and the existing shortcomings.Based on our analysis,we conclude that existing congestion identification and measurement methods are still inadequate.Three problems are anticipated for further study:maintaining the consistency between congestion and overinvestment,considering joint weak disposability assumption between desirable outputs and undesirable outputs,and quantifying the degree of congestion. | Xiantong Ren Chen Jiang Mohammad Khoveyni Zhongcheng Guan Guoliang Yang | 2021 | Journal of Management Science and Engineering2021，6，4： | 0 |
| 13 | Ar Ion Implantation Induced Tc Degradation of YBa_(2)Cu_(3)O_(7-x) Thin Films显示文摘The Ar ion implantation induced changes of structure and transport properties of YBa_(2)Cu_(3)O_(7-x) thin films were studied as a function of fluence.Both the zero resistance temperature Tc and the critical current density Jc decrease rapidly with fluence,however,the transition temperature onset almost remains constant at low fluences.At dose of 1.2×10^(13)Ar/cm^(2),the sample has a metal to semiconductor phase transition.When the fluence further increases,a crystalline to amorphous phase transition occurs,and the sample becomes insulator. | LI Yijie REN Congxin CHEN Guoliang LIN Zixin ZOU Shichang | 1991 | Chinese Physics Letters1991，8，3： | 0 |
| 14 | Unlocking high-rate O3 layered oxide cathode for Na-ion batteries via ion migration path modulation显示文摘O3-NaNi1/3Fe1/3Mn1/3O2is a promising layered cathode material with high specific capacity,low cost,and simple synthesis.However,sluggish kinetic hindrance is attributed to the size discrepancy between the large Na-ion and narrow tetrahedral interstitial positions,leading to inferior rate capacity and low reversible capacity.Herein,F with light-weight and strong electronegativity is introduced to substitute O atoms in the bulk structure,which intensifies the bond strength of transition metal and oxygen and enlarges the Na+diffusion channel.In addition,density-functional theory(DFT) calculations demonstrate that the electrostatic interaction is weakened between Na+in the tetrahedral site and the transitionmetal cation directly below it,dramatically reducing the migration barriers of Na+diffusion.Consequently,the as-obtained NaNi1/3Fe1/3Mn1/3O1.95F0.05sample displays outstanding rate performance of 86.7 mA h g^(-1)at 10 C and excellent capacity retention of 84.1% after 100 cycles at 2 C.Moreover,a full cell configuration using a hard carbon anode reaches the energy density of 307.7 Wh kg^(-1).This strategy paves the way for novel means of modulating the Na-ion migration path for high-rate O3-type layered cathode materials. | Guoliang Liu Weile Xu Jianghua Wu Yong Li Liping Chen Shuyue Li Qinghui Ren Juan Wang | 2023 | Journal of Energy Chemistry2023，，8： | 0 |
| 15 | Toughened (Ti_(0.2)Zr_(0.2)Hf_(0.2)Nb_(0.2)Ta_(0.2))B_(2)–SiC composites fabricated by one-step reactive sintering with a unique SiB_(6) additive显示文摘High-entropy diboride has been arousing considerable interest in recent years.However,the low toughness and damage tolerance limit its applications as ultra-high-temperature structural materials.Here we report that a unique SiB_(6) additive has been first incorporated as boron and silicon sources to fabricate a high-entropy boride(Ti_(0.2)Zr_(0.2)Hf_(0.2)Nb_(0.2)Ta_(0.2))B_(2)–SiC composite though one-step boro/carbothermal reduction reactive sintering.A synergetic effect of high-entropy sluggish diffusion and SiC secondary phase retarded the grain growth of the(Ti_(0.2)Zr_(0.2)Hf_(0.2)Nb_(0.2)Ta_(0.2))B_(2)–51SiC composites.The small grain size was beneficial to shorten the diffusion path for mass transport,thereby enhancing the relative density to~99.3%.These results in an increase of fracture toughness from~5.2 in HEBS-1900 to~7.7 MPa·m^(1/2) in HEBS-2000,which corresponded to a large improvement of 48%.The improvement was attributed to a mixed mode of intergranular and transgranular cracking for offering effective pinning in crack propagation,resulting from balanced grain boundary strength collectively affected by improved densification,solid solution strengthening,and incorporation of SiC secondary phase. | Wei Hao Xinzhe Lu Ling Li Tao Wang Guoliang Ren Huangyue Cai Xiaofeng Zhao Dongyun Wang Na Ni | 2024 | Journal of Advanced Ceramics2024，13，1： | 0 |
| 16 | Securing acoustics-based short-range communication systems:an overview显示文摘Mobile devices such as smartphones and tablets have continued to grow in recent years.Nowadays,people rely on these ubiquitous smart devices and carry them everywhere in their daily lives.Acoustic signal,as a simple and prevalent transmitting vector for end-to-end communication,shows unique characteristics comparing with another popular communication method,i.e.,optical signal,especially on the applications performed over smart devices.Acoustic signal does not require line-of-sight when transmission,the computational power of most smart devices are sufficient to modulate/demodulate acoustic signal using software acoustic modem only,which can be easily deployed on current off-the-shelf smart devices.Therefore,many acoustics-based short range communication systems have been developed and are used in sensitive applications such as building access control and mobile payment system.However,past work shows that an acoustic eavesdropper snooping on the communication between a transmitter and its legitimate receiver can easily break their communication protocol and decode the transmitted information.To solve this problem,many solutions have been proposed to protect the acoustic signal against eavesdroppers.In this overview,we explore the designs of existing solutions,the corresponding implementations,and their methodologies to protect acoustic signal communication.For each dependable and secure acoustics-based short range communication system,we present the major technical hurdles to be overcome,the state-of-the-art,and also offer a vision of the future research issues on this promising technology. | CHEN Si QIN Zhan XING Guoliang REN Kui | 2016 | Journal of Communications and Information Networks2016，1，4： | 0 |
| 17 | Normalised stabilisation for singular semi-Markov jump systems with discontinuous jump states显示文摘This paper addresses the almost surely exponential(ASE)stabilisation problem of continuoustime singular semi-Markov jump systems(s-MJSs),where the state at jump instants is discontinuous.Because of such a discontinuity existing,the consistency of initial condition at jump instants is impossible to be ensured but is an essential issue of singular systems.A proportional-derivative(PD)state feedback controller is proposed to deal with it such that the closed-loop singular s-MJSs is normal and ASE-stable.New sufficient conditions for the existence of such a controller are derived as linear matrix inequalities,which includes some existing considered systems as special situations.Two numerical examples are used to show the effectiveness and superiority of the methods. | Guoliang Wang Yunshuai Ren | 2022 | Journal of Control and Decision2022，9，3： | 0 |
| 18 | Study on the spatiotemporal variability of eco-hydrological characteristics of the rivers in the Longitudinal Range-Gorge Region and their driving forces显示文摘Taking two typical rivers in high mountains and steep gorge areas as example,this paper analyzes the spetiotemporal variability of the eco-hydrological characteristics and the driving forces leading to changes.Firstly,based on the species-environmental data processing,this paper adopts canonical correspondence analysis(CCA)method to identify the environmental factors influencing the distribu- tion of river bank vegetation.Secondly,this study uses the ecological diversity Index to represent the spatiotemporel variability of ecological characteristics.Thirdly,this paper uses the multiple correlation method to analyze the relationship between the hydrological factors and meteorological factors,and to identify the key factors leading to the hydrological regime changes.At last,based on the analysis of basin water quality data,this paper analyzes the regularity of spatiotemporal variability and its driving forces.By the systematic analysis on the outcome,we could get that the spatiotemporel distribution of eco-hydrological characteristics shows the regular changes from the upstream to downstream(from the north to the south),and the spatiotemporal variability of eco-hydrological characteristics is typical from the east to the west.Altitude,aspect and water distribution are the primary natural driving forces leading to the spatiotemporel variability of eco-hydrological characteristics;and exploitation and op- eration of hydroelectric power station,construction of road on the river bank,and basin land utilization are the main human driving forces. | HU Bo CUI BaoShan WEI GuoLiang ZHAI HongJuan REN HuaLi | 2007 | Chinese Science Bulletin2007，52，A02： | 0 |
| 19 | Spatial correlations in ground motion intensity measuring from the 2023 Türkiye earthquake显示文摘When evaluating an area's seismic risk or resilience,it is necessary to use the spatial correlation to analyze the ground motion parameters of multiple sites together in an earthquake.These two large earthquakes in Türkiye provided the possibility for spatial correlation analysis of ground motion intensity measurements in this area.Based on the strong motion records provided by The Disaster and Emergency Management Authority of Türkiye(AFAD),this study uses the local ground motion prediction equation in Türkiye to give spatial correlation analysis of Intensity Measurements.This study gives an exponential model based on a semivariogram and compares it with the correlation model obtained from previous studies. | Guoliang Shao Ruizhi Wen Hongwei Wang Yeifei Ren Baofeng Zhou | 2024 | Earthquake Research Advances2024，4，1： | 0 |
