| 1 | An Ultra‑Durable Windmill‑Like Hybrid Nanogenerator for Steady and Efficient Harvesting of Low‑Speed Wind Energy显示文摘Wind energy is one of the most promising and renewable energy sources;however,owing to the limitations of device structures,collecting low-speed wind energy by triboelectric nanogenerators(TENGs)is still a huge challenge.To solve this problem,an ultra-durable and highly efficient windmill-like hybrid nanogenerator(W-HNG)is developed.Herein,the W-HNG composes coupled TENG and electromagnetic generator(EMG)and adopts a rotational contact-separation mode.This unique design efficiently avoids the wear of friction materials and ensures a prolonged service life.Moreover,the generator group is separated from the wind-driven part,which successfully prevents rotation resistance induced by the friction between rotor and stator in the conventional structures,and realizes low-speed wind energy harvesting.Additionally,the output characteristics of TENG can be complementary to the different performance advantages of EMG to achieve a satisfactory power production.The device is successfully driven when the wind speed is 1.8 m s−1,and the output power of TENG and EMG can achieve 0.95 and 3.7 mW,respectively.After power management,the W-HNG has been successfully applied as a power source for electronic devices.This work provides a simple,reliable,and durable device for improved performance toward large-scale low-speed breeze energy harvesting. | Ying Zhang Qixuan Zeng Yan Wu Jun Wu Songlei Yuan Dujuan Tan Chenguo Hu Xue Wang | 2020 | Nano-Micro Letters2020，12，12： | 6 |

| 4 | rAAV/ABAD-DP-6His attenuates oxidative stressinduced injury of PC12 cells显示文摘Our previous studies have revealed that amyloid β(Aβ)-binding alcohol dehydrogenase(ABAD) decoy peptide antagonizes Aβ42-induced neurotoxicity. However, whether it improves oxidative stress injury remains unclear. In this study, a recombinant adenovirus constitutively secreting and expressing Aβ-ABAD decoy peptide(rAAV/ABAD-DP-6His) was successfully constructed. Our results showed that rAAV/ABAD-DP-6His increased superoxide dismutase activity in hydrogen peroxide-induced oxidative stress-mediated injury of PC12 cells. Moreover, rAAV/ABADDP-6His decreased malondialdehyde content, intracellular Ca2+ concentration, and the level of reactive oxygen species. rAAV/ABAD-DP-6His maintained the stability of the mitochondrial membrane potential. In addition, the ATP level remained constant, and apoptosis was reduced. Overall, the results indicate that rAAV/ABAD-DP-6His generates the fusion peptide, Aβ-ABAD decoy peptide, which effectively protects PC12 cells from oxidative stress injury induced by hydrogen peroxide, thus exerting neuroprotective effects. | Mingyue Jia Mingyu Wang Yi Yang Yixin Chen Dujuan Liu Xu Wang Lei Song Jiang Wu Yu Yang | 2014 | Neural Regeneration Research2014，9，5： | 3 |
| 5 | English and Chinese language frequency time series analysis显示文摘English and Chinese language frequency time series (LFTS) were constructed based on an English and two Chinese novels. Methods of statistical hypothesis testing were adopted to test the nonlinear properties of the LFTS. Results suggest the series exhibited non-normal, auto-correlative, and stationary characteristics. Moreover, we found that LFTS follow the power law distributions, and thereby we investigated the fractal structure, long range correlation, and intermittency, which indicated the self-similarity features of LFTS, and also provided hints that human societies are likely to share some universal properties. | DENG WeiBing WANG DuJuan LI Wei WANG Qiuping Alexandre | 2011 | Chinese Science Bulletin2011，56，34： | 3 |
| 6 | Dynamic behavior of bridge-erecting machine subjected to moving mass suspended by wire ropes显示文摘The dynamic behavior of a bridge-erecting machine,carrying a moving mass suspended by a wire rope,is investigated.The bridge-erecting machine is modelled by a simply supported uniform beam,and a massless equivalent 'spring-damper' system with an effective spring constant and an effective damping coefficient is used to model the moving mass suspended by the wire rope.The suddenly applied load is represented by a unitary Dirac Delta function.With the expansion method,a simple closed-form solution for the equation of motion with the replaced spring-damper-mass system is formulated.The characters of the rope are included in the derivation of the differential equation of motion for the system.The numerical examples show that the effects of the damping coefficient and the spring constant of the rope on the deflection have significant variations with the loading frequency.The effects of the damping coefficient and the spring constant under different beam lengths are also examined.The obtained results validate the presented approach,and provide significant references in the design process of bridgeerecting machines. | Shaopu YANG Xueqian FANG Jianchao ZHANG Dujuan WANG | 2016 | Applied Mathematics and Mechanics(English Edition)2016，37，6： | 3 |
| 7 | STRENGTH ANALYSIS OF CLAMPING IN MICRO/NANO SCALE EXPERIMENTS显示文摘Two kinds of clamping in micro/nano scale experiments are investigated in this paper,one based on electron-beam-induced deposition,and the other on the van der Waals interaction.The clamping strength and mechanism are analyzed both theoretically and experimentally.The influence of relative humidity on the micro/nano clamping and the method of electrostatic clamping are discussed.The clamping strength and performance of different clamping methods are compared considering the size and material of the clamped objects,and the application environments. | Liang Liu Dujuan Zeng Xianlong Wei Qing Chen Xide Li | 2009 | Acta Mechanica Solida Sinica2009，22，6： | 2 |
| 8 | A NEW IMAGE QUALITY ASSESSMENT BASED ON HVS显示文摘This letter proposes a new kind of image quality philosophy—Modulate Quality based on Fixation Points (MQFP) based on Human Visual System (HVS) model. Dissimilar to the former HVS-based quality assessment, the new measure emphasizes particularly on modeling the jumping phenomenon of human sight instead of modeling the visual perception of human. In other words, to model the HVS using fixation points and stay-frequency instead of Contrast Sensitive Function (CSF) etc. which models the visual perception of HVS. The experiment on various frequency-distortion images indicates that the new measure is correlated with the subjective judgment more than the former HVS-based measure and is a robust measure. | DuJuan YuYinglin XieShengli | 2005 | Journal of Electronics(China)2005，22，3： | 2 |

| 20 | Prehibernation Energy Storage in Heilongjiang Brown Frogs(Rana amurensis) from Five Populations in North China显示文摘Energy storage is an important component in the life history of species that directly influences survival and reproduction. The energetic demands of amphibian reproduction can differ between the sexes, with environmental conditions, reproductive pattern or process of the species, and depending upon the timing of breeding, and the reproductive season for a species. Surprisingly, comparative studies of pre-hibernation energy storage for anuran populations from different latitudes are relatively few in Asia, especially in China. Here we investigated the patterns of pre-hibernation energy storage of Heilongjiang brown frogs Rana amurensis, based on five populations along a finely latitudinal gradient in north China(40.7–43.7°N). We found that pre-hibernation energy storage of the frogs did not show a clear latitudinal cline, but differed strongly between the sexes, with males depositing more energy reserves into the muscle and liver, whereas females accumulate more energy in the gonads. The sexual differences in energy storage may result from differential timing of energy allocation for reproduction. | Wei CHEN Tianpei GUAN Lina REN Dujuan HE Ying WANG Xin LU | 2015 | Asian Herpetological Research2015，6，1： | 0 |
