1High-resolution pseudo-inverse ghost imaging显示文摘We present a pseudo-inverse ghost imaging(PGI) technique which can dramatically enhance the spatial transverse resolution of pseudo-thermal ghost imaging(GI). In comparison with conventional GI, PGI can break the limitation on the imaging resolution imposed by the speckle’s transverse size on the object plane and also enables the reconstruction of an N-pixel image from much less than N measurements. This feature also allows high-resolution imaging of gray-scale objects. Experimental and numerical data assessing the performance of the technique are presented.Wenlin Gong 2015Photonics Research2015,3,5:24

5Ghost imaging for an axially moving target with an unknown constant speed显示文摘The influence of the axial relative motion between the target and the source on ghost imaging(GI) is investigated.Both the analytical and experimental results show that the transverse resolution of GI is reduced as the deviation of the target’s center position from the optical axis or the axial motion range increases. To overcome the motion blur,we propose a deblurring method based on speckle-resizing and speed retrieval, and we experimentally validate its effectiveness for an axially moving target with an unknown constant speed. The results demonstrated here will be very useful to forward-looking GI remote sensing.Xiaohui Li Chenjin Deng Mingliang Chen Wenlin Gong Shensheng Han 2015Photonics Research2015,3,4:15
6Performance analysis of ghost imaging lidar in background light environment显示文摘The effect of background light on the imaging quality of three typical ghost imaging(GI) lidar systems(namely narrow pulsed GI lidar, heterodyne GI lidar, and pulse-compression GI lidar via coherent detection) is investigated. By computing the signal-to-noise ratio(SNR) of fluctuation-correlation GI, our analytical results, which are backed up by numerical simulations, demonstrate that pulse-compression GI lidar via coherent detection has the strongest capacity against background light, whereas the reconstruction quality of narrow pulsed GI lidar is the most vulnerable to background light. The relationship between the peak SNR of the reconstruction image andσ(namely, the signal power to background power ratio) for the three GI lidar systems is also presented, and theresults accord with the curve of SNR-σ.CHENJIN DENG LONG PAN CHENGLONG WANG XIN GAO WENLIN GONG SHENSHENG HAN 2017Photonics Research2017,5,5:13
7Effects of Filler Metal Composition on Inclusions and Inclusion Defects for ER NiCrFe-7 Weldments显示文摘The effects of filler metal(FM) composition on inclusions and inclusion defects for ER NiCrFe-7 weldments have been investigated and analyzed.Results show that as Al,Ti content in FM increases from 0.14 wt%Al,0.30 wt% Ti to 0.42 wt%Al,0.92 wt%Ti,the Al,Ti reduction will increase during welding.Inclusion defects(point-like defects named by welding workers) are prone to form in the high Al,Ti content weldments.Inclusion defects with Mg,Ca,Al,and Ti as major metallic elements have been found on the surface and interior of the weldments,as Al,Ti content in FM is over 0.29 wt%Al,0.62 wt%Ti.Less Ti content in FM cannot prevent ductility-dip-cracking(DDC) through producing enough intragranular precipitates and lessening intergranular M_(23)C_6 precipitates.Nb can be used to replace Ti to reduce the sensitivity of the DDC in the NiCrFe-7 alloy weldments.Wenlin Mo Shanping Lu Dianzhong Li Yiyi Li 2013Journal of Materials Science & Technology2013,29,5:11
8Retrospective study on Professor Zhongying Zhou's experience in Traditional Chinese Medicine treatment on diabetic nephropathy显示文摘OBJECTIVE:To study and analyze the etiology and pathogenesis,diagnosis and prescription for cases of diabetic nephropathy(DN) treated by Professor Zhongying Zhou(Prof.Zhou) with the help of dada mining technique,so as to inherit his clinical experience and academic thoughts.METHODS:After pretreatment of the medical record information,statistical software SPSS 13.0 was used to analyze and process the standardized data using the descriptive analysis,cluster analysis and association rules.RESULTS:Ninety-four entries derived from Traditional Chinese Medicine(TCM) four-diagnostic information were selected.Through data mining,the highest frequency was yellow-thin-greasy tongue coating,followed by dark tongue,and then by thready-slippery pulse.The main self-conscious symptoms were limb numbness,dry mouth,frequent micturition,etc.With respect to pathogenesis,the etiology related to kidney reached 73.46%.The frequency of pathological factors for deficiency,blood stasis,heat,dampness,phlegm and dryness were 137.65%,80.25%,78.40%,48.77%,21.60%,and 14.20% respectively.A total of 236 kinds of herbs were used 2913 person times,averaging 17.98 herbs per prescription.CONCLUSION:The pathological location of DN is in the kidney.The pathogenesis of the disease is deficiency in origin and excess in superficiality,the former of which include deficiency of the liver and kidney,and deficiency of both Qi and Yin.The main pathological factors are blood stasis,heat,dampness,phlegm,and dryness;and they act upon each other to form the complex pathogenesis in terms of blood stasis-heat,dampness-heat,phlegm-heat,and dryness-heat.All the above factors are always crucial in the aggravation of DN throughout the whole course of its pathological evolution.Kelei Su Fangshi Zhu Lizhong Guo Yao Zhu Wenlin Li Xingjiang Xiong 2013Journal of Traditional Chinese Medicine2013,33,2:11
9Long-and short-chain AHLs affect AOA and AOB microbial community composition and ammonia oxidation rate in activated sludge显示文摘Quorum sensing(QS)regulation of the composition of ammonia-oxidising archaea(AOA)and ammonia-oxidising bacteria(AOB)communities and functions in wastewater treatment was investigated.Specifically,we explored the role of N-acyl-L-homoserine lactones(AHLs)in microbial community dynamics in activated sludge.On average,the specific ammoniaoxidising-rate increased from 1.6 to 2.8 mg NH_4^+-N/g MLSS/hr after treatment with long-chain AHLs for 16 days,and the addition of AHLs to sludge resulted in an increased number of AOA/AOB amoA genes.Significant differences were observed in the AOA communities of control and AHL-treated cultures,but not the AOB community.Furthermore,the dominant functional AOA strains of the Crenarchaeota altered their ecological niche in response to AHL addition.These results provide evidence that AHLs play an important role in mediating AOA/AOB microbial community parameters and demonstrate the potential for application of QS to the regulation of nitrogen compound metabolism in wastewater treatment.Jie Gao Yu Duan Ying Liu Xuliang Zhuang Yichen Liu Zhihui Bai Wenlin Ma Guoqiang Zhuang 2019Journal of Environmental Sciences2019,31,4:11
10Berberine sensitizes ovarian cancer cells to cisplatin through miR-21/PDCD4 axis显示文摘最近的研究证明了 microRNA-21 (miR-21 ) 贡献肿瘤抵抗到化疗。有趣地,我们发现了 berberine 能在几根癌症房间线禁止 miR-21 表示。在这研究,我们调查了 berberine 是否能调制卵巢的癌症房间的敏感到 cisplatin 并且探索机制。被孵化, berberine 与 cisplatin 结合了的 cisplatin 抵抗的 SKOV3 房间独自比 cisplatin 有 signicantly 更低的幸存组和提高的导致 cisplatin 的 apoptosis。Berberine 能在卵巢的癌症禁止 miR-21 表示和功能,由它的目标 PDCD4 的改进出现在卵巢的癌症的重要肿瘤 suppressor。结果建议 berberine 能经由在卵巢的癌症房间调整 miR-21/PDCD4 轴调制 cisplatin 的敏感。Shiguo Liu Yue Fang Huiling Shen Wenlin Xu Hao Li 2013Acta Biochimica et Biophysica Sinica2013,45,9:9
11Effects of Boron on the Microstructure,Ductility-dip-cracking,and Tensile Properties for NiCrFe-7 Weld Metal显示文摘The distribution of boron and the microstructure of grain boundary(GB) precipitates(M_(23)(C,B)_6 and M_2B)have been analyzed with their effects on the susceptibility of ductility-dip-cracking(DDC) and tensile properties for NiCrFe-7 weld metal,using optical microscopy(OM),secondary ion mass spectroscopy(SIMS),scanning electron microscopy(SEM),and transmission electron microscopy(TEM).The results show that boron segregates at GBs in NiCrFe-7 weld metal during the welding process.The segregation of boron at GBs promotes the formation of continuous M_(23)(C,B)_6 carbide chains and M_2B borides along GBs.The addition of boron aggravates GB embrittlement and causes more DDC in the weld metal,by its segregation at GBs presenting as an impurity,and promoting the formation of larger and continuous M_(23)(C,B)_6 carbides,and M_2B borides along GBs.DDC in the weld metal deteriorates the ductility and tensile strength of the weld metal simultaneously.Wenlin Mo Xiaobing Hu Shanping Lu Dianzhong Li Yiyi Li 2015Journal of Materials Science & Technology2015,31,12:9
12Streamflow responses to climate change and LUCC in a semi-arid watershed of Chinese Loess Plateau显示文摘Climate change and Land Use/Cover Change(LUCC) have been identified as two primary factors affecting watershed hydrological regime. This study analyzed the trends of streamflow, precipitation, air temperature and potential evapotranspiration(PET) from 1962 to 2008 in the Jihe watershed in northwestern Loess Plateau of China using the Mann-Kendall test. The streamflow responses to climate change and LUCC were quantified independently by the elasticity method. The results show that the streamflow presented a dramatic decline with a turning point occurred in 1971, while the precipitation and PET did not change significantly. The results also show that the temperature rose markedly especially since 1990 s with an approximate increase of 1.74°C over the entire research period(1962–2008). Using land use transition matrix, we found that slope cropland was significantly converted to terrace between 1970 s and 1990 s and that forest cover increased relatively significantly because of the Grain for Green Project after 2000. The streamflow reduction was predominantly caused by LUCC and its contribution reached up to 90.2%, while the contribution of climate change to streamflow decline was only 9.8%. Although the analytical results between the elasticity method and linear regression model were not satisfactorily consistent, they both indicated that LUCC(human activity) was the major factor causing streamflow decline in the Jihe watershed from 1962 to 2008.LI Qingyun SUN Yanwei YUAN Wenlin LYU Subing WAN Fang 2017Journal of Arid Land2017,9,4:9
13Expression of neurocan mRNA and ultrastructure of brain tissue after cerebral ischemia and reperfusion in stroke-prone renovascular hypertensive rats treated by electroacupuncture显示文摘We established a stroke-prone renovascular hypertensive rat model by bilateral constriction of the renal artery with sliver loop clips. After ten weeks, middle cerebral artery occlusion was induced for 2 hours. The rats then received electro-acupuncture at Baihui (DU 20) and Dazhui (DU 14) after onset of ischemia for 30 days. In situ hybridization study showed that electroacupuncture significantly reduced the number of neurocan mRNA-positive cells in the ischemic penumbra and hippocampal tissues of rats. Electron microscopy results demonstrated that the structure of neurons and blood vessels in the ischemic tissues were restored with electroacupuncture. Overall, these data suggest that electroacupuncture may protect neurons against ischemic reperfusion injury in stroke-prone renovascular hypertensive rats, which may be regulated by downregulation of expression of nerve inhibitory factor neurocan mRNA.Feng Tan Saiying Wan Haike Wu Qiwen HUO Jinliang Wang Wenlin Chen Meifeng Fang Xiaolin Liu Xuewen Wang Jingbo Sun 2011Neural Regeneration Research2011,6,36:8

15WWOX suppresses KLF5 expression and breast cancer cell growth显示文摘The WW domain-containing oxidoreductase(WWOX) is a tumor suppressor in a variety of cancers, including breast cancer. Reduced WWOX expression is associated with the basal-like subtype and a relatively poor disease-free survival rate among breast cancer patients. Though several WWOX partners have been identified, the functional mechanisms of WWOX's role in cancers have not been fully addressed to date. In the current study, we found WWOX suppresses expression of KLF5—an oncogenic transcription factor—at protein level, and suppresses cancer cell proliferation in both bladder and breast cancer cell lines. Furthermore, we demonstrated that WWOX physically interacts with KLF5 via the former's WW domains and the latter's PY motifs. Interestingly, we found the expression of WWOX negatively correlates with KLF5 expression in a panel of breast cancer cell lines. Taken together, we conjecture that WWOX may suppress cancer cell proliferation partially by reducing the expression of KLF5.Fei Ge Wenlin Chen Runxiang Yang Zhongmei Zhou Nanshan Chang Ceshi Chen Tianning Zou Rong Liu Jing Tan Guosheng Ren 2014Chinese Journal of Cancer Research2014,26,5:7

17Far-field super-resolution ghost imaging with a deep neural network constraint显示文摘Ghost imaging(GI)facilitates image acquisition under low-light conditions by single-pixel measurements and thus has great potential in applications in various fields ranging from biomedical imaging to remote sensing.However,GI usually requires a large amount of single-pixel samplings in order to reconstruct a high-resolution image,imposing a practical limit for its applications.Here we propose a far-field super-resolution GI technique that incorporates the physical model for GI image formation into a deep neural network.The resulting hybrid neural network does not need to pre-train on any dataset,and allows the reconstruction of a far-field image with the resolution beyond the diffraction limit.Furthermore,the physical model imposes a constraint to the network output,making it effectively interpretable.We experimentally demonstrate the proposed GI technique by imaging a flying drone,and show that it outperforms some other widespread GI techniques in terms of both spatial resolution and sampling ratio.We believe that this study provides a new framework for GI,and paves a way for its practical applications.Fei Wang Chenglong Wang Mingliang Chen Wenlin Gong Yu Zhang Shensheng Han Guohai Situ 2022Light(Science & Applications)2022,11,1:6

19Assessing the benthic habitat quality in the Huanghe(Yellow River) Estuary and its adjacent areas using AMBI and M-AMBI显示文摘The protection of the biological diversity and the maintenance of the regional ecological integrity for the Huanghe(Yellow River) Estuary and its adjacent areas are practically significant and valuable. However, frequent human activities and natural climate changes have caused vigorous disturbances on the ecosystem in these sea areas. An objective assessment on the benthic habitat quality(BHQ) of the Huanghe Estuary and its adjacent areas is conducted, using AZTI's Marine Biotic Index(AMBI) and multivariate AMBI(M-AMBI) based on the data of macrobenthos in May and August 2011. The results show that both the indices do not correlate significantly, and their assessment results are greatly different. All of the samples assessed using the AMBI were 'high' or 'good', because the ecological group I(EGI) and the ecological group II(EGII) were dominant macrobenthic ecological groups in the research area. Owing to a low species' richness and a high individual abundance in some samples, the BHQ levels using the M-AMBI were worse than those of the AMBI. Significant correlations are observed between the M-AMBI, water depth, bottom water salinity and dissolved inorganic nitrogen, thus the M-AMBI could sensitively respond to environmental changes and distinguish influences from uninfluenced stations, but the AMBI could not. The consistent results between the AMBI and the M-AMBI mainly appeared in the uninfluenced(undisturbed or slightly disturbed) stations. Therefore, the M-AMBI is more effective than the AMBI in assessing the benthic habitat quality in the Huanghe Estuary and its adjacent areas. Using the M-AMBI to assess the BHQ of the Huanghe Estuary and its adjacent areas, the results show that 3% of the stations are undisturbed and the BHQs are 'high', and 61% of the stations are slightly disturbed and those of the BHQ are 'good', and the rest are meanly disturbed and those of the BHQ are 'moderate'.LUO Xianxiang ZHANG Juan YANG Jianqiang SONG Wenpeng CUI Wenlin 2014Acta Oceanologica Sinica2014,33,9:6
20Effect of microwave pre-treatment on physical quality,bioactive compounds,safety risk factor,and storage stability of peanut butter显示文摘Microwave,as a new heat treatment technology,has the characteristics of uniform and fast heating speed.It is an energy-saving technology known for improving oilseed product quality.Its efficiency mainly depends on the roasting power and time.However,the production of high-quality peanut butter using short-time roasting con-ditions are limited.Herein,we determined an appropriate microwave roasting power and time for peanuts and evaluated its impacts on the quality of peanut butter.Different roasting powers(400 W,800 W and 1200 W)and times(4,4.5,5,and 5.5 min)were preliminarily tested.Among them,800 W at 5 min was the most suitable.The roasting efficiency was further evaluated using color,sensory,bioactive compounds,storage stability,and safety risk factors of peanut butter produced from four peanut cultivars(Silihong,Baisha-1016,Yuanza-9102,and Yuhua-9414).The pre-treated butter obtained from three cultivars(Silihong,Yuanza-9102,and Yuhua-9414)with moisture content between 5%and 7.2%had a similar sensory score(6-7)as the commercial on a 9-point hedonic scale compare to the other.The color of the pre-treated peanut butter varies statistically with the commercial but remained in the recommended range of Hunter L*values of 51-52,respectively,for high initial moisture peanut cultivars.The total polyphenol(35.20-31.59±0.59μmol GAE/g)and tocopherol(19.05±0.35 mg/100 g)content in the butter obtained from three cultivars(Yuahua-9102,Yuhua,and Baisha-1016)and Silihong respectively,were significantly(P<0.05)higher than those in the commercial butter.The induction times of all pre-treated butter(19.80±0.99-7.84±0.07 h)were significantly(P<0.05)longer during storage at accelerated temperature than commercial samples.In addition,no benzo[a]pyrene was found in the pre-treated samples.Collectively,the microwave pretreated peanut butter was superior to the commercial one.These findings provided data support and a reference basis to promote microwave use for peanut butter production.Jefferson G.Degon Chang Zheng Abdeen Elkhedir Bo Yang Qi Zhou Wenlin Li 2021Oil Crop Science2021,6,3:6
