| 2 | Effects of Rare Earth elements on microstructure evolution and mechanical properties of 718H pre-hardened mold steel显示文摘718 H Pre-ha rdened mold steels with diffe rent Rare Earth(RE) contents were prepared to investigate the influence of RE on microstructure evolution and mechanical properties through a series of experiments and theoretical analysis.The results indicated that the toal oxygen(T.O) content decreased from 15 ppm to 6 ppm with 0.022 wt% RE addition,which is attributed to the active chemical properties of RE elements.For test steels,RE additions of 0.012 wt% and 0.022 wt% were significantly effective for refining inclusions by eliminating 11.5% large-sized inclusions with diameter exceeding 10 μm compared with that of ORE steel.RE addition contributed to modify irregular MnS and Al2 O3 inclusions into ellipsoidal RE-inclusions(RE2 O,RES,RE2 O2 S and REAlO3).The purification of molten steel and the modification of inclusions by RE treatment have significant effects on improvement of the fatigue crack growth tests(FCG) inhibition ability and impact energy as well as the isotropy.However,excessive addition of RE elements(0.07 wt%)seriously reduced the impact energy,ultimate tensile strength and FCG inhibition ability due to rapidly increase of the volume fraction of large-sized inclusions.In addition to the inclusions formed by RE treatment,trace solid solution RE atoms improve the stability of undercooled austenite,resulting in the transformation region of bainite and perlite of 0.07 RE steel shifting to the bottom right and prolonging the incubation period compared with that of ORE steel. | Hanghang Liu Paixian Fu Hongwei Liu Yanfei Cao Chen Sun Ningyu Du Dianzhong Li | 2020 | Journal of Materials Science & Technology2020,47,15: | 11 |
| 3 | Commissioning progress of the FAST显示文摘The Five-hundred-meter Aperture Spherical radio Telescope(FAST) was completed with its main structure installed on September 25, 2016, after which it entered the commissioning phase. This paper aims to introduce the commissioning progress of the FAST over the past two years. To improve its operational reliability and ensure effective observation time, FAST has been equipped with a real-time information system for the active reflector system and hierarchical commissioning scheme for the feed support system, which ultimately achieves safe operation of the two systems. For meeting the high-performance indices, a highprecision measurement system was set up based on the effective control methods that were implemented for the active reflector system and feed support system. Since the commissioning of the FAST, a low-frequency ultra-wideband receiver and 19-beam1.05-1.45 GHz receiver have been mainly used. Telescope efficiency, pointing accuracy, and system noise temperature were completely tested and ultimately achieved the acceptance indices of the telescope. The FAST has been in the process of national acceptance preparations and has begun to search for pulsars. In the future, it will still strive to improve its capabilities and expand its application prospects. | Peng Jiang YouLing Yue HengQian Gan Rui Yao Hui Li GaoFeng Pan JingHai Sun DongJun Yu HongFei Liu NingYu Tang Lei Qian JiGuang Lu Jun Yan Bo Peng ShuXin Zhang QiMing Wang Qi Li Di Li | 2019 | Science China(Physics,Mechanics & Astronomy)2019,62,5: | 11 |
| 4 | Characterization of spontaneous otoacoustic emissions in 2–4 day old neonates with respect to gender and ear显示文摘BACKGROUND: Spontaneous otoacoustic emissions (SOAEs) are regarded as a valuable audio- metric parameter that objectively reflects the function of outer hair cells (OHCs). Many studies have reported that the incidence of SOAEs in adults is less than 50%. Therefore, measurement of SOAEs may be of little value to clinical examinations. However, the incidence of SOAEs in infants and neonates is higher than in adults. OBJECTIVE: To analyze the basic characteristics of SOAEs in 2–4 day old neonates, and to dem- onstrate the difference in OHC function between sexes and ears. DESIGN, TIME AND SETTING: Neurophysiological contrast study, performed in the Department of Neonates, Beijing Chaoyang Hospital, Capital Medical University, between December 2007 and August 2008. PARTICIPANTS: A total of 112 newborns (224 ears) consisting of 59 females and 53 males were included in this study. METHODS: The probe was adapted and embedded in the neonate external auditory canal with a foam rubber earplug after checking and clearing up the outer ear canal. The presence of SOAEs was determined when the signal amplitude had a clear peak exceeding –30 dB, or was 3 dB above the noise floor. MAIN OUTCOME MEASURES: The incidence of SOAEs, the number of SOAE signal peaks, and the maximal tension of SOAEs. RESULTS: The incidence in females (79.7%) was higher than males (76.4%) (P > 0.05), and the incidence in right ears (86.6%) was higher than in left ears (69.6%) (P < 0.05). There were no sig- nificant difference in the number of SOAE peaks between females and males (4.49 vs. 4.28), or between right ears and left ears (4.62 vs. 4.12) (P > 0.05). The mean maximum SOAE level per ear in females (–3.29 ± 9.28) dB sound pressure level (SPL) was slightly higher than that in males (–3.91 ± 9.14) dB SPL (P > 0.05). Also, the mean maximum SOAE level in right ears (–2.03 ± 9.11) dB SPL was higher than in left ears (–5.50 ± 9.65) dB SPL (P < 0.05). The maximum SOAE level showed a positive correlation with maximum SOAE number in emitting ears (r = 0.55, P < 0.01). CONCLUSION: The incidence of SOAEs in neonates is high (78.1%) within 4 days of birth. The in-cidence of SOAEs and the maximum SOAE level exhibited a significant difference between right and left ears, but the difference between sexes was insignificant. Both the strongest SOAE signal peak and number of SOAEs per ear are representative of the function OHCs. | Jinfeng Liu Baoyu Shi Ningyu Wang Jinlan Li | 2009 | Neural Regeneration Research2009,4,1: | 8 |
| 5 | Effects of Double Harvesting on Heavy Metal Uptake by Six Forage Species and the Potential for Phytoextraction in Field显示文摘The pollution of soils by heavy metals has dramatically increased in recent decades. Phytoextraction is a technology that extracts elements from polluted soils using hyperaccumulator plants. The selection of appropriate plant materials is an important factor for successful phytoextraction in field. A field study was conducted to compare the efficiency of six high-biomass forage species in their phytoextraction of heavy metals(Cd, Pb, and Zn) from contaminated soil under two harvesting strategies(double harvesting or single harvesting). Among the tested plants, amaranth accumulated the greatest amounts of Cd and Zn, whereas Rumex K^(-1) had the highest amount of Pb in the shoot under both double and single harvesting. Furthermore, double harvesting significantly increased the shoot biomass of amaranth, sweet sorghum and sudangrass and resulted in higher heavy metal contents in the shoot. Under double harvesting, the total amounts of extracted Cd, Pb and Zn(i.e., in the first plus second crops) for amaranth were 945, 2 650 and 12 400 g ha^(-1), respectively, the highest recorded among the six plant species. The present results indicate that amaranth has great potential for the phytoextraction of Cd from contaminated soils. In addition, the double harvesting method is likely to increase phytoextraction efficiency in practice. | LI Ningyu GUO Bin LI Hua FU Qinglin FENG Renwei DING Yongzhen | 2016 | Pedosphere2016,26,5: | 8 |
| 6 | Grey-matter volume as a potential feature for the classification of Alzheimer's disease and mild cognitive impairment: an exploratory study显示文摘Specific patterns of brain atrophy may be helpful in the diagnosis of Alzheimer's disease(AD). In the present study, we set out to evaluate the utility of grey-matter volume in the classification of AD and amnestic mild cognitive impairment(aMCI) compared to normal control(NC) individuals. Voxel-based morphometric analyses were performed on structural MRIs from 35 AD patients, 27 aMCI patients, and 27 NC participants. A two-sample two-tailed t-test was computed between the NC and AD groups to create a map of abnormal grey matter in AD. The brain areas with significant differences were extracted as regions of interest(ROIs), and the grey-matter volumes in the ROIs of the aMCI patients were included to evaluate the patterns of change across different disease severities. Next, correlation analyses between the grey-matter volumes in the ROIs and all clinical variables were performed in aMCI and AD patients to determine whether they varied with disease progression. The results revealed significantly decreased grey matter in the bilateral hippocampus/parahippocampus, the bilateral superior/middle temporal gyri, and the right precuneus in AD patients.The grey-matter volumes were positively correlated with clinical variables. Finally, we performed exploratory linear discriminative analyses to assess the classifying capacity of grey-matter volumes in the bilateral hippocampus and parahippocampus among AD, aMCI, and NC. Leave-one-out crossvalidation analyses demonstrated that grey-matter volumes in hippocampus and parahippocampus accurately distinguished AD from NC. These findings indicate that grey-matter volumes are useful in the classification of AD. | Yane Guo Zengqiang Zhang Bo Zhou Pan Wang Hongxiang Yao Minshao Yuan Ningyu An Haitao Dai Luning Wang Xi Zhang Yong Liu | 2014 | Neuroscience Bulletin2014,30,3: | 7 |
| 7 | Detection of cognitive impairment in patients with obstructive sleep apnea hypopnea syndrome using mismatch negativity显示文摘In this experiment,97 patients with obstructive sleep apnea hypopnea syndrome were divided into three groups(mild,moderate,severe) according to minimum oxygen saturation,and 35 healthy subjects were examined as controls.Cognitive function was determined using the mismatch negativity paradigm and the Montreal Cognitive Assessment.The results revealed that as the disease worsened,the mismatch negativity latency was gradually extended,and the amplitude gradually declined in patients with obstructive sleep apnea hypopnea syndrome.Importantly,mismatch negativity latency in severe patients with a persistent time of minimum oxygen saturation < 60 seconds was significantly shorter than that with a persistent time of minimum oxygen saturation > 60 seconds.Correlation analysis revealed a negative correlation between minimum oxygen saturation latency and Montreal Cognitive Assessment scores.These findings indicate that intermittent night-time hypoxemia affects mismatch negativity waveforms and Montreal Cognitive Assessment scores.As indicators for detecting the cognitive functional status of obstructive sleep apnea hypopnea syndrome patients,the sensitivity of mismatch negativity is 82.93%,the specificity is 73.33%,the accuracy rate is 81.52%,the positive predictive value is 85.00%,the negative predictive value is 70.21%,the positive likelihood ratio is 3,and the negative likelihood ratio is 0.23.These results indicate that mismatch negativity can be used as an effective tool for diagnosis of cognitive dysfunction in obstructive sleep apnea hypopnea syndrome patients. | Xiaohui Wen Ningyu Wang Jinfeng Liu Zhanfeng Yan Zhonghai Xin | 2012 | Neural Regeneration Research2012,7,20: | 6 |
| 8 | Zirconium-containing UiO-66 as an efficient and reusable catalyst for transesterification of triglyceride with methanol显示文摘Zirconium-based MOFs of the UiO family have attracted considerable attention due to their high thermal,chemical and mechanical stability. With the aim of further exploring the applications of zirconium-based UiO-66 in acid-catalyzed reactions and elucidating the effects of the defects in UiO-66 materials on their catalytic performances, in this work, a series of zirconium-containing UiO-66 samples were synthesized by varying the synthesis temperatures and BDC/Zr(terephthalic acid/ZrCl_4) ratios in the synthesis system.The synthesized UiO-66 samples were characterized by X-ray diffraction(XRD), N_2 adsorption-desorption,scanning electron microscopy(SEM), thermogravimetrical analysis(TGA), temperature-programmed desorption of NH_3(NH_3-TPD). Their catalytic performances were investigated in transesterification of tributyrin and soybean oil with methanol. The results showed that UiO-66 samples with different amounts of defects could be successfully prepared by varying the synthesis temperatures and/or the BDC/Zr ratios used in the synthesis system. The catalytic activities of the UiO-66 materials greatly depended on their linker defects and enhanced with the increase of the defect amount. The UiO-66 was an efficient catalyst for transesterification of tributyrin and soybean oil with methanol under mild reaction conditions and its catalytic activity was comparable to other solid acid catalysts reported in the literatures. The UiO-66 catalyst was relatively stable and could be reused. | Fan Zhou Ningyue Lu Binbin Fan Huigang Wang Ruifeng Li | 2016 | Journal of Energy Chemistry2016,25,5: | 6 |
| 9 | Effect of vanadium micro-alloying on the microstructure evolution and mechanical properties of 718H pre-hardened mold steel显示文摘The effects of different contents of vanadium(V)(0.1,0.2,and 0.3 wt%)on the microstructure evolution and mechanical properties of 718H steel were investigated.The precipitate was characterized by means of atom probe tomography(APT)and bright-field transmission electron microscopy(TEM).The increase in V content has great benefits for strength,but has an adverse effect on impact toughness.The strength increase can be attributed to the influence of V addition on dislocation density,misorientation gradient,and fine scale MC precipitates.Precipitation strengthening mainly contributes to the V-added steel by analyzing various strengthening mechanisms.However,fine scale MC precipitates can pin dislocation leading to a decrease in its mobility.A large number of immovable dislocations will increase the dislocation accumulation,internal stress and brittle cracking,resulting in a gradual decrease in impact toughness with the V addition.In addition,compared with V-free steel,the dissolved V content in austenite decreases the grain boundary energy and inhibits the diffusion of the C atoms,ultimately reducing the transformation range of pearlite(P). | Hanghang Liu Paixian Fu Hongwei Liu Chen Sun Ningyu Du Dianzhonga Li | 2019 | Journal of Materials Science & Technology2019,35,11: | 5 |
| 10 | Local inhibition of GABA affects precedence effect in the inferior colliculus显示文摘The precedence effect is a prerequisite for faithful sound localization in a complex auditory environment,and is a physiological phenomenon in which the auditory system selectively suppresses the directional information from echoes.Here we investigated how neurons in the inferior colliculus respond to the paired sounds that produce precedence-effect illusions,and whether their firing behavior can be modulated through inhibition with gamma-aminobutyric acid(GABA).We recorded extracellularly from 36 neurons in rat inferior colliculus under three conditions: no injection,injection with saline,and injection with gamma-aminobutyric acid.The paired sounds that produced precedence effects were two identical 4-ms noise bursts,which were delivered contralaterally or ipsilaterally to the recording site.The normalized neural responses were measured as a function of different inter-stimulus delays and half-maximal interstimulus delays were acquired.Neuronal responses to the lagging sounds were weak when the inter-stimulus delay was short,but increased gradually as the delay was lengthened.Saline injection produced no changes in neural responses,but after local gamma-aminobutyric acid application,responses to the lagging stimulus were suppressed.Application of gamma-aminobutyric acid affected the normalized response to lagging sounds,independently of whether they or the paired sounds were contralateral or ipsilateral to the recording site.These observations suggest that local inhibition by gamma-aminobutyric acid in the rat inferior colliculus shapes the neural responses to lagging sounds,and modulates the precedence effect. | Yanjun Wang Ningyu Wang Dan Wang Jun Jia Jinfeng Liu Yan Xie Xiaohui Wen Xiaoting Li | 2014 | Neural Regeneration Research2014,9,4: | 4 |

| 12 | Analysis of a Mesoscale Convective System that Produced a Single Sprite显示文摘Sprites are brief optical emissions occurring above thunderstorms. Features of sprites and their parent thunderstorms and lightning activities have been studied by many researchers. Here, we report a single sprite recorded over a mesoscale convective system during its life cycle in Northeast China. The results show that the sprite might have been a dancing one,with a 20 km horizontal displacement from its parent cloud-to-ground flash(CG) and a 38 ms time delay; all the sprite elements occurred during the continuing current process of the parent flash. The peak current of the parent CG was the largest during the almost one-hour time window containing the sprite, and the absolute values of all the negative flashes were smaller than 100 k A during the same time period and did not produce sprite. The sprite did not occur during the time period in which the maximum area of the thunderstorm reached. The occurrence of sprite corresponded well with the decay of the thunderstorm convection, and no significant relationship between the occurrence of sprite and the increase in the 30–35 d BZ and 35–40 d BZ interval was found. The large wind gradient in the 8–12 km region of the thunderstorm may have played an important role in the sprite production. | Jing YANG Gaopeng LU Ningyu LIU Haihua CU Yu WANG Morris COHEN | 2017 | Advances in Atmospheric Sciences2017,34,2: | 3 |
| 13 | Identification of anti-Gram-negative bacteria agents targeting the interaction between ribosomal proteins L12 and L10显示文摘Gram-negative bacteria have become the main pathogens and cause serious clinical problems with increased morbidity and mortality. However, the slow discovery of new antimicrobial agents is unable to meet the need for the treatment of bacterial infections caused by drug-resistant strains. The interaction of L12 and L10 is essential for ribosomal function and protein synthesis. In this study, a yeast two-hybrid system was established to successfully detect the interaction between L12 and L10 proteins from gram-negative bacteria Escherichia coli, which allows us to screen compounds that specifically disrupt this interaction. With this system, we identified two compounds IMB-84 and IMB-87 that block L12-L10 interaction and show bactericidal activity against E. coli. We used glutathione-S-transferase(GST) pull-down and surface plasmon resonance(SPR) assays to demonstrate that these compounds disrupt L12-L10 interaction in vitro and the target of compounds was further confirmed by the overexpression of target proteins. Moreover, protein synthesis and elongation factor G-dependent GTPase activities are inhibited by two compounds. Therefore, we have identified two antibacterial agents that disrupt L12-L10 interaction by using yeast two-hybrid system. | Weiwei Wang Chao Liu Ningyu Zhu Yuan Lin JiANDong Jiang Yanchang Wang Yan Li Shuyi Si | 2018 | Acta Pharmaceutica Sinica B2018,8,5: | 3 |

| 16 | Comparison of 16 slice multi-detector computed tomography and breath hold 3D magnetic resonance angiography in the detection of coronary stenosis显示文摘Objective To compare 16-slice multi-detector spiral computed tomography (MDCT) and breathhold 3D magnetic resonance (MR) coronary angiography in the visualization of coronary arteries and the accuracy of detecting significant (> 50%) coronary stenoses in patients with suspected coronary artery disease. Methods Forty patients were examined by 16-slice CT (GE, Lightspeedl6)and MR (GE,Twinspeed) within 3 days; 31 of them underwent conventional coronary angiography (CAG) within 2 weeks after CT and MR scan. CT was performed with 16× 1.25 mm detector collimation, 0.5 s rotation time and images were reconstructed at 60%-75% of the cardiac cycle. MR was performed with breath hold 3D FIESTA (TR4.0 ms, TE1.7 ms, flip angle 65, slice thickness 3 mm, FOV 280 mm, matrix 256× 192). Mean heart rate was 63 ± 5.8 bpm and β-blocker was used in 24 patients. MR and CT image quality was evaluated in 9 coronary segments (RCA1, RCA2, RCA3, LM, LAD1, LAD2, LAD3, LCX1, LCX2) using a four-point grading scale.Sensitivity, specificity, positive predictive value, negative predictive value and accuracy were calculated for detection of significant stenosis using CAG as the gold standard. Results 16-slice CT showed higher image quality in most coronary segments except RCA2.Forty-three segments were diagnosed as significant stenosis by CAG, 36 and 27 of these were correctly detected by CT and MR respectively. Sensitivity, specificity, positive predictive value, and negative predictive value of 16-slice CT and MR for detecting significant stenosis were 83 %, 84 %, 49 %, 97 % and 63 %, 90 %, 55 %, 93 %, respectively. Conclusion Sixteen-slice CT showed higher image quality in most coronary segments excepted for middle RCA. 16-slice CT had higher sensitivity than MR for detection of coronary significant stenosis, whereas MR had higher specificity than CT. Both CT and MR showed high negative predictive value,which is useful for excluding coronary stenosis in symptomatic patients. | Xin LIU Zulong CAI Youquan CAI Shaohong ZHAO Ningyu AN Yuangui GAO | 2006 | Journal of Geriatric Cardiology2006,3,1: | 2 |
| 17 | Mutations in DNAH8 contribute to multiple morphological abnormalities of sperm flagella and male infertility显示文摘Asthenoteratospermia is an important cause of male infertility.Here,we report two infertile patients with severe asthenoteratospermia accompanied by new genetic abnormality.Whole-exome sequencing and bioinformatics analysis suggested that compound heterozygous mutations in DNAH8(MIM:603337)may be responsible for multiple morphological abnormalities of the sperm flagella(MMAF).Immunofluorescence assay showed that DNAH8 protein expression was significantly decreased in the sperm tail of the patients,and electron microscopy exhibited an abnormal flagellum ultrastructure,while clinical pregnancy could be achieved by intracytoplasmic sperm injection.Therefore,the compound heterozygous mutations in the DNAH8 gene may be responsible for MMAF. | Mingxiang Weng Yanwei Sha Yu Zeng Ningyu Huang Wensheng Liu Xinzong Zhang Huiliang Zhou | 2021 | Acta Biochimica et Biophysica Sinica2021,53,4: | 2 |
| 18 | Effect of age on click-evoked otoacoustic emission A systematic review显示文摘OBJECTIVE:The aims of this study were to investigate the changes of the total intensity of transient evoked otoacoustic emission(TEOAE) and signal-to-noise ratio in various frequency bands as a function of aging,and to explore the role of age-related decline of cochlear outer hair cells.DATA SOURCES:The literature was searched using the PubMed database using 'transient-evoked otoacoustic emissions' as a keyword.Articles were limited as follows:Species was 'Humans';languages were 'English and Chinese';publication date between 1990-01-01 and 2010-12-31.The references of the found were also searched to obtain additional articles.DATA SELECTION:Inclusion criteria:(1) Articles should involve the total TEOAE level or signal-to-noise ratio.(2) The measurement and analysis system used was Otodynamics ILO analysis system(ILO88,ILO92,ILO96 or ILO292).(3) Studies involved groups of greater than 10 subjects and TEOAE results were from normally hearing ears.(4) If more papers from the same author or laboratory analyzed the same subjects,only one was used.MAIN OUTCOME MEASURES:The correlations of the age scale with the total level and signal-to-noise ratio of TEOAE was determined,respectively.RESULTS:(1) TEOAE total level gradually increased until 2 months of age,and then decreased with increasing age.Significant negative correlations between total TEOAE level and age were found(r =-0.885,P = 0.000).(2) The most rapid decrease of TEOAE amplitude occurred at 1 year old.The total TEOAE level decreased about 4.25 dB SPL between 2 months to 1 year old,then about 0.26-0.52 dB SPL from 1 year to 10 years old,about 0.23 dB SPL from 11 years to 25 years old,and about 0.14 dB SPL from 26 years to 60 years old.(3) The signal-to-noise ratio in the frequency bands centered at 1.5,2,3 and 4 kHz decreased with increasing age after 2 months of age.Significant negative correlations between the signal-to-noise ratio and age were found for frequency bands ranging from 1.5 kHz to 4 kHz,with the highest correlations at 4 kHz(r =-0.890,P < 0.01),then at 3 kHz(r =-0.889,P < 0.01),at 2 kHz(r =-0.850,P < 0.01) and at 1.5 kHz(r =-0.705,P < 0.05).Conversely,a positive correlation between the signal-to-noise ratio centered at 1 kHz and age was found,but was not statistically significant(r = 0.298,P = 0.374).CONCLUSION:The total TEOAE response level decreased with increasing age after the first 2 months of age.The signal-to-noise ratio also decreased with increasing age in frequency bands above 1.5 kHz.The signal-to-noise ratio in higher frequencies decreased faster than in lower frequencies,leading to the maximum signal-to-noise ratio shift form 3.2-4.0 kHz in neonates to 1.5 kHz in adults,and further decreasing the total TEOAE response level.The age-related TEOAE spectrum peak shift is most likely because the outer hair cells functioning in higher frequencies are more prone to damage than those for lower frequencies. | Jinfeng Liu Ningyu Wang | 2012 | Neural Regeneration Research2012,7,11: | 2 |
