| 6 | SURFACE STRESS EFFECT IN MECHANICS OF NANOSTRUCTURED MATERIALS显示文摘This review article summarizes the advances in the surface stress effect in mechanics of nanostructured elements,including nanoparticles,nanowires,nanobeams,and nanofilms,and heterogeneous materials containing nanoscale inhomogeneities.It begins with the fundamental formulations of surface mechanics of solids,including the definition of surface stress as a surface excess quantity,the surface constitutive relations,and the surface equilibrium equations.Then,it depicts some theoretical and experimental studies of the mechanical properties of nanostructured elements,as well as the static and dynamic behaviour of cantilever sensors caused by the surface stress which is influenced by adsorption.Afterwards,the article gives a summary of the analytical elasto-static and dynamic solutions of a single as well as multiple inhomogeneities embedded in a matrix with the interface stress prevailing.The effect of surface elasticity on the diffraction of elastic waves is elucidated.Due to the difficulties in the analytical solution of inhomogeneities of complex shapes and configurations,finite element approaches have been developed for heterogeneous materials with the surface stress.Surface stress and surface energy are inherently related to crack propagation and the stress field in the vicinity of crack tips.The solutions of crack problems taking into account surface stress effects are also included.Predicting the effective elastic and plastic responses of heterogeneous materials while taking into account surface and interface stresses has received much attention.The advances in this topic are inevitably delineated.Mechanics of rough surfaces appears to deserve special attention due to its theoretical and practical implications.Some most recent work is reviewed.Finally,some challenges are pointed out.They include the characterization of surfaces and interfaces of real nanomaterials,experimental measurements and verification of mechanical parameters of complex surfaces,and the effects of the physical and chemical processes on the surface properties,etc. | Jianxiang Wang Zhuping Huang Huiling Duan Shouwen Yu Xiqiao Feng Gangfeng Wang Weixu Zhang Tiejun Wang | 2011 | Acta Mechanica Solida Sinica2011，24，1： | 11 |
| 7 | Effectiveness and safety of moxibustion in treatment of lumbar disc herniation: a systematic review and Meta-analysis显示文摘OBJECTIVE: To evaluate the effectiveness and safety of moxibustion therapy in the treatment of lumbar disc herniation (LDH). METHODS: Four Chinese databases and three English databases were searched from their inception to April 2018.Randomized controlled trials (RCTs) were included if moxibustion was used as the sole treatment or as a part of combination therapy with other treatments in patients with LDH. Two reviewers independently extracted the data and assessed the methodological quality using the Cochrane criteria for the risk of bias. The Meta-analysis was performed using Review Manager 5.3 software. RESULTS: In total, 16 RCTs including 1186 patients with LDH were analyzed. The Meta-analysis showed favorable effects of moxibustion in combination with massage therapy on the visual analog scale score compared with massage therapy alone [mean difference (MD)=? 1.32, 95% confidence interval (CI)(? 2.12,? 0.51), P = 0.001]. The subgroup Meta-analysis failed to show favorable effects of electro-acupuncture plus moxibustion on the efficacy rate compared with electro-acupuncture alone [relative risk (RR)= 1.06, 95% CI (0.98, 1.14), P = 0.15]. However, acupuncture or massage therapy plus moxibustion improved the efficacy rates compared with acupuncture or massage therapy alone [RR = 1.33, 95% CI (1.18, 1.49), P < 0.000 01][χ^2 = 2.76, P = 0.25, I2 = 27%],[RR = 1.15, 95% CI (1.06, 1.25), P = 0.001][χ^2 = 0.00, P = 0.95, I2 = 0%]. With respect to the Japanese Orthopaedic Association (JOA) scores, acupuncture or massage therapy in addition to moxibustion produced results different from those of acupuncture or massage therapy alone [MD = 5.58, 95% CI (4.15, 7.00), P < 0.000 01][χ^2 = 0.58, P = 0.45, I2 = 0%],[MD = 3.61, 95% CI (3.01, 4.21), P < 0.000 01]. There were no significant differences in the JOA score for subjective symptoms, objective symptoms, daily living ability, and other parameters. In six RCTs, no adverse reactions occurred during moxibustion. CONCLUSION: Whether moxibustion is an effective intervention for LDH is unclear because of the small sample size of qualified RCTs and the high risk of bias. More high-quality RCTs that overcome the methodological shortcomings of the existing evidence are needed. | Wang Yang Zhang Huiling Xia Liping Sun Zhiling Xu Xiao Du Shizheng | 2019 | Journal of Traditional Chinese Medicine2019，39，5： | 11 |
| 8 | Uniform blow-up profiles and boundary layer for a parabolic system with localized nonlinear reaction terms显示文摘This paper deals with the blow-up properties of the solution to a semilinear parabolic system with localized nonlinear reaction terms, subject to the null Dirichlet boundary condition. We first give sufficient conditions for that the classical solution blows up in the finite time, secondly give necessary conditions and a sufficient condition for that two components blow up simultaneously, and then obtain the uniform blow-up profiles in the interior. Finally we describe the asymptotic behavior of the blow-up solution in the boundary layer. | LI Huiling & WANG Mingxin Department of Mathematics, Southeast University, Nanjing 210018, China Department of Mathematics, Xuzhou Normal University, Xuzhou 221116, China | 2005 | Science China Mathematics2005，48，2： | 9 |
| 9 | The maximum coseismic vertical surface displacement and surface deformation pattern accompanying the Ms 8.0 Wenchuan earthquake显示文摘The amount of coseismic deformation and its distribution of the Wenchuan earthquake provide important scientific bases for revealing the mechanisms of earthquake preparation and characterizing the rupture propagation of the Wenchuan earthquake. The previous studies have indicated that the earthquake ruptured the middle-to-north segment of the Longmenshan central fault and the middle segment of the Longmenshan range-front fault, which are characterized by two surface rupture zones of 240 km and 90 km in length, respectively. Based on the pre-earthquake information and photos of landforms and buildings obtained through ge-ologic and geomorphic survey of the area around Shaba Village of Beichuan County, Sichuan Province and the extensive interview with local villagers, we measured the displacements of the major terrain features and the dislocated buildings by total station instruments and differential GPS and obtained the maximum vertical displacement of 9±0.5 m and right-lateral displacement of 2±0.5 m around the Zou’s house in Shaba Village. Though the near-surface deformation exhibits a normal faulting around Shaba Village, the dynamic environment has not changed on the whole. The NW wall of the fault uplifted but without gravity gliding as normally occurring on the hanging wall of a normal fault, which proves that the 9±0.5 m displacement should be the maximum coseismic vertical displacement of the May 12, 2008 Ms 8.0 Wenchuan earthquake. | Ran YongKang Shi Xiang Wang Hu Chen LiChun Chen Jie Liu RuiChun Gong Huiling | 2010 | Chinese Science Bulletin2010，55，9： | 9 |
| 10 | Self-Powered Implantable Skin-Like Glucometer for Real-Time Detection of Blood Glucose Level In Vivo显示文摘Implantable bioelectronics for analyzing physiological biomarkers has recently been recognized as a promising technique in medical treatment or diagnostics. In this study, we developed a self-powered implantable skinlike glucometer for real-time detection of blood glucose level in vivo. Based on the piezo-enzymatic-reaction coupling effect of GOx@ZnO nanowire, the device under an applied deformation can actively output piezoelectric signal containing the glucose-detecting information. No external electricity power source or battery is needed for this device, and the outputting piezoelectric voltage acts as both the biosensing signal and electricity power. A practical application of the skin-like glucometer implanted in mouse body for detecting blood glucose level has been simply demonstrated. These results provide a new technique path for diabetes prophylaxis and treatment. | Wanglinhan Zhang Linlin Zhang Huiling Gao Wenyan Yang Shuai Wang Lili Xing Xinyu Xue | 2018 | Nano-Micro Letters2018，10，2： | 9 |
| 11 | Critical velocity in phosphorus exchange processes across the sediment-water interface显示文摘Sediments are ultimate sinks of nutrients in lakes that record the pollution history evolutionary processes, and anthropogenic activities of a lake. However, sediments are considered as inner sources of environmental factor changes such as the variation in hydrodynamic conditions because of the nutrients they release. How does this process happen? This study investigates a typical nutrient phosphorus(P) exchange among sediment, suspended particle matter(SPM), and water. Compared with numerical and experimental studies, this study confirms that the critical velocity that occurs at a lower flow rate state exists in the range of 7 to 15 cm/sec. Critical velocity below the critical flow rate promotes the migration of particulate phosphorus(PP) to the SPM. On the other hand, critical velocity above the critical flow rate promotes the release of PP in water. | Jun Wan Ze Wang Zhijie Li Huiling Duan HezhongYuan | 2013 | Journal of Environmental Sciences2013，25，10： | 9 |
| 12 | A LysM Receptor Heteromer Mediates Perception of Arbuscular Mycorrhizal Symbiotic Signal in Rice显示文摘Symbiotic microorganisms improve nutrient uptake by plants.To initiate mutualistic symbiosis with arbus-cular mycorrhizal(AM)fungi,plants perceive Myc factors,including lipochitooligosaccharides(LCOs)and short-chain chitooligosaccharides(CO4/CO5),secreted by AM fungi.However,the molecular mechanism of Myc factor perception remains elusive.In this study,we identified a heteromer of LysM receptor-like kinases consisting of OsMYR1/OsLYK2 and OsCERK1 that mediates the perception of AM fungi in rice.CO4 directly binds to OsMYR1,promoting the dimerization and phosphorylation of this receptor complex.Compared with control plants,Osmyr1 and Oscerk1 mutant rice plants are less sensitive to Myc factors and show decreased AM colonization.We engineered transgenic rice by expressing chimeric receptors that respectively replaced the ectodomains of OsMYR1 and OsCERK1 with those from the homologous Nod factor receptors MtNFP and MtL YK3 of Medicago truncatula.Transgenic plants displayed increased cal-cium oscillations in response to Nod factors compared with control rice.Our study provides significant mechanistic insights into AM symbiotic signal perception in rice.Expression of chimeric Nod/Myc recep-tors achieves a potentially important step toward generating cereals that host nitrogen-fixing bacteria. | Jiangman He Chi Zhang Huiling Dai Huan Liu Xiaowei Zhang Jun Yang Xi Chen Yayun Zhu Dapeng Wang Xiaofeng Qi Weichao Li Zhihui Wang Guoyong An Nan YU Zuhua He Yong-Fei Wang Youli Xiao Peng Zhang Ertao Wang | 2019 | Molecular Plant2019，12，12： | 9 |
| 13 | Focal adhesion protein Kindlin-2 regulates bone homeostasis in mice显示文摘Our recent studies demonstrate that the focal adhesion protein Kindlin-2 is critical for chondrogenesis and early skeletal development. Here, we show that deleting Kindlin-2 from osteoblasts using the 2.3-kb mouse Col1 a1-Cre transgene minimally impacts bone mass in mice, but deleting Kindlin-2 using the 10-kb mouse Dmp1-Cre transgene, which targets osteocytes and mature osteoblasts, results in striking osteopenia in mice. Kindlin-2 loss reduces the osteoblastic population but increases the osteoclastic and adipocytic populations in the bone microenvironment. Kindlin-2 loss upregulates sclerostin in osteocytes,downregulates β-catenin in osteoblasts, and inhibits osteoblast formation and differentiation in vitro and in vivo. Upregulation ofβ-catenin in the mutant cells reverses the osteopenia induced by Kindlin-2 deficiency. Kindlin-2 loss additionally increases the expression of RANKL in osteocytes and increases osteoclast formation and bone resorption. Kindlin-2 deletion in osteocytes promotes osteoclast formation in osteocyte/bone marrow monocyte cocultures, which is significantly blocked by an anti-RANKLneutralizing antibody. Finally, Kindlin-2 loss increases osteocyte apoptosis and impairs osteocyte spreading and dendrite formation.Thus, we demonstrate an important role of Kindlin-2 in the regulation of bone homeostasis and provide a potential target for the treatment of metabolic bone diseases. | Huiling Cao Qinnan Yan Dong Wang Yumei Lai Bo Zhou Qi Zhang Wenfei Jin Simin Lin Yiming Lei Liting Ma Yuxi Guo Yishu Wang Yilin Wang Xiaochun Bai Chuanju Liu Jian QFeng Chuanyue Wu Di Chen Xu Cao Guozhi Xiao | 2020 | Bone Research2020，8，1： | 8 |

| 16 | Plasma Nesfatin-1 concentration and its correlation with HPA axis in depression model rats显示文摘Objective To explore plasma Nesfatin-1 concentration and its correlation with hypothalamic pituitary adrenal(HPA) axis in depression model rats. Methods Twelve SD rats were randomly divided into normal control group(NCG) and depression model group(DMG). DMG received 5 consecutive weeks of 7 different chronic unpredictable mild stress(CUMS). The behavior of rats was evaluated by an open field test,sucrose preference test,and forced swimming test(FST). The concentration of plasma corticosterone and Nesfatin-1 were measured with an enzyme-linked immuno-sorbent assay(ELISA). Results Compared with NCG,DMG had a lower weight gain,lower index of sucrose preference and spent longer time being immobile in FST while all of these differences were statistically significant(P<0.05). The plasma concentrations of corticosterone and Nesfatin-1 were significantly higher in DMG than in theN CG(P<0.05). The plasma concentration of Nesfatin-1in DMG was positively correlated with the plasma corticosterone concentration. Conclusion CUMS could induce depression-like behavior in rats and increase the plasma concentration of Nesfatin-1 and corticosterone,while the HPA axis hyperactivity induced by CUMS may be associated with the increased concentration of Nesfatin-1. | WANG Gaohua WU Shengjuan WANG Huiling Wei Yanyan Gao Guoqing Li Jiangbo | 2016 | 国际精神病学杂志2016，43，3： | 6 |
| 17 | A Covert Communication Method Using Special Bitcoin Addresses Generated by Vanitygen显示文摘As an extension of the traditional encryption technology,information hiding has been increasingly used in the fields of communication and network media,and the covert communication technology has gradually developed.The blockchain technology that has emerged in recent years has the characteristics of decentralization and tamper resistance,which can effectively alleviate the disadvantages and problems of traditional covert communication.However,its combination with covert communication thus far has been mostly at the theoretical level.The BLOCCE method,as an early result of the combination of blockchain and covert communication technology,has the problems of low information embedding efficiency,the use of too many Bitcoin addresses,low communication efficiency,and high costs.The present research improved on this method,designed the V-BLOCCE which uses base58 to encrypt the plaintext and reuses the addresses generated by Vanitygen multiple times to embed information.This greatly improves the efficiency of information embedding and decreases the number of Bitcoin addresses used.Under the premise of ensuring the order,the Bitcoin transaction OP_RETURN field is used to store the information required to restore the plaintext and the transactions are issued at the same time to improve the information transmission efficiency.Thus,a more efficient and feasible method for the application of covert communication on the blockchain is proposed.In addition,this paper also provides a more feasible scheme and theoretical support for covert communication in blockchain. | Lejun Zhang Zhijie Zhang Weizheng Wang Rasheed Waqas Chunhui Zhao Seokhoon Kim Huiling Chen | 2020 | Computers, Materials & Continua2020，，10： | 6 |
| 18 | Two-port network model and startup criteria for thermoacoustic oscillators显示文摘The startup process of a thermoacoustic engine is a self-excited oscillation process generated in inhomogeneous acoustic media. To reveal these coupling relations between various influential factors is an important task of basic research on thermoacoustics. In this paper thermoacoustic engines are regarded as thermoacoustic oscillators consisting of the active network and the passive network. Accordingly, the two-port Y-parameter for relevant component is derived, and standing wave and traveling wave thermoacoustic engine are described by the negative-resistance and feedback model, respectively. The relevant two-port network topology is given as well. The startup criteria for thermoacoustic oscillators are obtained by using Nyquist instability criterion. The model prediction of startup parameters, particularly, startup frequency and mode characteristic are in agreement with that of experimental results reported in the literature. Moreover, with topological graphs it is verified that standing wave engines would start up in a negative-resistance state and there would exist high frequency modes in thermoacoustic-Stirling engines. By investigating into the frequency response of thermoacoustic system, this method proposed can achieve such an objective that these effects of operating and structural parameters of engine on startup modes and startup temperature can be revealed in an analytical way. Thus this approach to test and check thermal stability can be provided in a design phase, instead of using empirical frequency to design thermoacoustic systems. | HU XingHua ZHANG XiaoQing WANG HuiLing SHU ShuiMing | 2009 | Chinese Science Bulletin2009，54，2： | 6 |
