1Deep-learning-based information mining from ocean remote-sensing imagery显示文摘With the continuous development of space and sensor technologies during the last 40 years,ocean remote sensing has entered into the big-data era with typical five-V(volume,variety,value,velocity and veracity)characteristics.Ocean remote-sensing data archives reach several tens of petabytes and massive satellite data are acquired worldwide daily.To precisely,efficiently and intelligently mine the useful information submerged in such ocean remote-sensing data sets is a big challenge.Deep learning-a powerful technology recently emerging in the machine-learning field-has demonstrated its more significant superiority over traditional physical-or statistical-based algorithms for image-information extraction in many industrial-field applications and starts to draw interest in ocean remote-sensing applications.In this review paper,we first systematically reviewed two deep-learning frameworks that carry out ocean remote-sensing-image classifications and then presented eight typical applications in ocean internal-wave/eddy/oil-spill/coastal-inundation/sea-ice/green-algae/ship/coral-reef mapping from different types of ocean remote-sensing imagery to show how effective these deep-learning frameworks are.Researchers can also readily modify these existing frameworks for information mining of other kinds of remote-sensing imagery.Xiaofeng Li Bin Liu Gang Zheng Yibin Ren Shuangshang Zhang Yingjie Liu Le Gao Yuhai Liu Bin Zhang Fan Wang 2020National Science Review2020,7,10:19
2Nickel-free Stainless Steel for Medical Applications显示文摘BIOSS4 steel is essentially a nickel-free austenitic stainless steel developed by the Institute of Metal Research, Chinese Academy of Sciences, in response to nickel allergy problems associated with nickel-containing stainless steels that are widely used in medical applications. The high nitrogen content of this steel effectively maintains the austenitic stability and also contributes to the high levels of corrosion resistance and strength. BIOSS4 steel possesses a good combination of high strength and toughness, better corrosion resistance, and better blood compatibility, in comparison with the medical 316L stainless steel. Potential applications of BIOSS4 steel can include medical implantation material and orthodontic or orthopedic devices, as well as jewelries and other decorations.Yibin REN, Ke YANG, Bingchun ZHANG, Yaqing WANG and Yong LIANGInstitute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China 2004Journal of Materials Science & Technology2004,20,5:11
3Meditation promotes insightful problem-solving by keeping people in amindful and alert conscious state显示文摘Although previous studies have shown that sleep can inspire insight,it is still unclear whether meditation can promote insight.Meditation differs from other types of passive rest such as relaxation and sleep because it requires full consciousness andmindfulness of targets such as one's breathing.Forty-eight university students without meditation experience were recruited to learn a simple meditation technique.They were given a list of 10 insight problems to solve (the pre-test session).In this study,we focused on the unsolved problems and examined if they could be successfully solved after a 20min rest interval with or without meditation.Results showed that relative to the control group that listened to Chinese or English words and made a language judgment,the groups who learned meditation successfully solved significantly more failed problems from the pre-test session,providing direct evidence for the role of meditation in promoting insight.Further analysis showed that maintaining amindful and alert state during meditation (raising a hand to report every 10 deep breaths compared to every 100 deep breaths) resulted in more insight regarding the failed items from the pre-test session.This implies that it was watchfulness in meditation,rather than relaxation,that actually contributed to insight.Consistently,in the meditation session or control task,the percentage of alpha waves—a brain index of mental relaxation—was negatively correlated with insight.These results suggest a meditation-based insight-promoting mechanism different from that involved in passive rest such as relaxation and sleep.REN Jun HUANG ZhiHui LUO Jing WEI GaoXia YING XiaoPing DING ZhiGuang WU YiBin LUO Fei 2011Science China(Life Sciences)2011,54,10:11
4High nitrogen nickel-free austenitic stainless steel:A promising coronary stent material显示文摘Currently commercialized coronary stents are mainly made of the medical 316L stainless steel and cobalt-based alloy(L605) due to their good combination of properties,especially excellent mechanical properties.However,the presence of high quantity of nickel and/or cobalt elements,the agents known to trigger the toxic and allergic responses,in these materials has caused many clinic concerns.The potential adverse effect of nickel ions release has prompted the development of high nitrogen nickel-free austenitic stainless steels for medical application.Nitrogen in steel is not only to replace the nickel but also improve the properties of steel.In this paper,the harmfulness and release of nickel from metallic stents,and the advantages in mechanical properties and hemocompatibility of high nitrogen nickel-free stainless steels for coronary stents are reviewed.Apart from the highlight of nickel-free,the superiority of high strength and better hemocompatibility of high nitrogen nickel-free stainless steels can guarantee to manufacture thinner strut coronary stents with remarkable anticoagulation ability.High nitrogen nickel-free stainless steels as a promising coronary stents material will attract more and more clinical doctors and stents makers to bring them into clinical application.YANG Ke REN YiBin WAN Peng 2012Science China(Technological Sciences)2012,55,2:7
5In vitro Study on a New High Nitrogen Nickel-free Austenitic Stainless Steel for Coronary Stents显示文摘Most commercialized coronary stents are made of 316L stainless steels due to its good combination of properties,and currently some new stents are made of cobalt-based alloy owing to its higher mechanical properties. However,the presence of high quantity of nickel and/or cobalt elements in these materials,which are known to trigger the toxic and allergic responses,has caused many concerns.Nickel-free austenitic stainless steels have been developed in order to solve these problems.In this paper,based on the development of a new Fe-Cr-Mn-Mo-N type high nitrogen nickel-free austenitic stainless steel,properties such as mechanical property,corrosion resistance in Hank s solution,and in vitro blood compatibility including the kinetic clotting time and the platelets adhesion,were investigated in comparison to the above two conventional materials,a 316L stainless steel and a Co-28Cr-6Mo alloy.The results showed that the new high nitrogen steel possessed better combination of mechanical properties,corrosion resistance and blood compatibility than those of 316L steel and the Co-28Cr-6Mo alloy,and can be a promising alternative material for manufacture of coronary stents.Yibin Ren Peng Wan Feng Liu Bingchun Zhang Ke Yang 2011Journal of Materials Science & Technology2011,27,4:6
6Effect of cold deformation on corrosion fatigue behavior of nickel-free high nitrogen austenitic stainless steel for coronary stent application显示文摘Due to the excellent mechanical properties, good corrosion resistance, high biocompatibility and nickelfree character, the high nitrogen nickel-free austenitic stainless steel(HNASS) becomes an ideally alternative material for coronary stents. Stent implantation works in harsh blood environment after a balloon dilatation, i.e., the material is used in a corrosive environment with a permanent deformation. The present study attempts to investigate effects of pre-straining on high-cycle fatigue behavior and corrosion fatigue behavior of HNASS in Hank's solution and the relevant mechanism for coronary stents application. It is found that higher pre-straining on HNASS results in higher strength and maintains almost same corrosion resistance. Fatigue limit of 0% HNASS is 550 MPa, while corrosion fatigue limit is 475 MPa. And improvement in fatigue limit of 20% and 35% pre-strained HNASS is in comparison with the 0% HNASS, while corrosion would undermine the fatigue behavior of HNASS. In a suitable range, the prestraining had a beneficial effect on corrosion fatigue strength of HNASS, such as nearly 300 MPa improved with 20% cold deformation. This result provides a good reference for predicting the life of HNASS stent and as well its design.Jun Li Yixun Yang Yibin Ren Jiahui Dong Ke Yang 2018Journal of Materials Science & Technology2018,34,4:4
7Model-independent trend of α-preformation probability显示文摘The α-preformation probability is directly deduced from experimental α decay energies and half-lives in an analytical way without any modified parameters. Several other model-deduced results, are used to compare with that of the present study. The key role played by the shell effects in the α-preformation process is indicated in all these cases. In detail, the α-preformation factors of different theoretical extractions are found to have similar behavior for one given isotopic chain, implying the model-independent varying trend of the preformation probability of α particle. In addition, the formation probability of heavier particle in cluster radioactivity is also obtained, and this confirms the relationship between the cluster preformation factor and the product of the cluster and daughter proton numbers.QIAN YiBin REN ZhongZhou 2013Science China(Physics,Mechanics & Astronomy)2013,56,8:3
8Analysis of Magnetism in High Nitrogen Austenitic Stainless Steel and Its Elimination by High Temperature Gas Nitriding显示文摘Stable austenitic structure in medical stainless steels is basically required for surgical implantation. A weak magnetism was found in a high nitrogen nickel-free austenitic stainless steel for cardiovascular stent application. This magnetic behavior in high nitrogen stainless steel was investigated by optical microscopy, X-ray diffraction (XRD), electron probe microanalysis (EPMA) and superconducting quantum interference device (SQUID). The results showed that the magnetism came from the composition segregation of ferrite formation elements such as Cr and Mo in the steel and some δ-ferrites were locally formed during the pressurized electroslag remelting process. The magnetism of high nitrogen stainless steel could be eliminated by a proper high temperature gas nitriding (HTGN).Peng Wan Yibin Ren Bingchun Zheng Ke Yang 2011Journal of Materials Science & Technology2011,27,12:3
9Cytocompatibility of High Nitrogen Nickel-Free Stainless Steel for Orthopedic Implants显示文摘Cytocompatibility of high nitrogen nickel-free stainless steel(HNS) with different nitrogen content was evaluated and compared with a conventional austenitic stainless steel 317L.The MTT assay(3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) was performed on MG63 osteoblasts to assess the cytotoxicity.The expression of selected marker typical of differentiated osteoblasts,such as alkaline phosphatase activity(AKP),was also monitored in MG63 cells cultured on the tested materials.As a result,HNS had higher cell growth than 317L;meanwhile the cytocompatibility was increased with increasing nitrogen content.Furthermore,HNS enhanced osteoblasts differentiation,as confirmed by AKP activity.Overall these facts indicated that HNS had higher cytocompatibility than 317L and the nitrogen content contributed to the higher cytocompatibility of HNS.The influence of nitrogen on surface energy further explained the cytocompatibility of HNS.Tianchi Ma Peng Wan Yuyan Cui Guirong Zhang Jiqiang Li Jihui Liu Yibin Ren Ke Yangg Li Lu 2012Journal of Materials Science & Technology2012,28,7:2
10Preliminary Study on Porous High-Manganese 316L Stainless Steel Through Physical Vacuum Dealloying显示文摘In this study, porous stainless steel was prepared successfully by physical vacuum dealloying method. The based alloy is high-manganese 316L-50 Mn alloy. The porous high-manganese 316L stainless steel showed a three-dimensional continuous porous structure with 1–2 μm pore size. Temperature was the key factor for the physical dealloying process to produce porous stainless steel, and the optimized treatment temperature was between 800 and 850 °C for the highmanganese 316L-50 Mn alloy.Yibin Ren Jun Li Ke Yang 2017Acta Metallurgica Sinica(English Letters)2017,30,8:2

19An RNA-RNA crosstalk network involving HMGB1 and RICTOR facilitates hepatocellular carcinoma tumorigenesis by promoting glutamine metabolism and impedes immunotherapy by PD-L1+ exosomes activity显示文摘Hepatocellular carcinoma(HCC)is the global leading cause of cancer-related deaths due to the deficiency of targets for precision therapy.A new modality of epigenetic regulation has emerged involving RNA-RNA crosstalk networks where two or more competing endogenous RNAs(ceRNAs)bind to the same microRNAs.However,the contribution of such mechanisms in HCC has not been well studied.Herein,potential HMGB1-driven RNA-RNA crosstalk networks were evaluated at different HCC stages,identifying the mT0RC2 component RICTOR as a potential HMGB1 ceRNA in HBV^(+)early stage HCC.Indeed,elevated HMGB1 mRNA was found to promote the expressio n of RICTOR mRNA through competitively bin ding with the miR-200 family,especially miR-429.Functio nal assays emplo ying overexpressi on or in terference strategies dem on strated that the HMGB1 and RICTOR 3zuntra nslated regions(UTR)epigenetically promoted the malignant proliferation,self-renewal,and tumorigenesis in HCC cells.Intriguingly,in terference agai nst HMGB1 and RICTOR in HCC cells promoted a stron ger an ti-PD-L1 immuno therapy resp on se,which appeared to associate with the production of PD-L1^(+)exosomes.Mechanistically,the HMGB1-driven RNA-RNA crosstalk network facilitated HCC cell glutamine metabolism via dual mechanisms,activating a positive feedback loop involving mT0RC2-AKT-C-MYC to upregulate glutamine synthetase(GS)expression,and inducing mTORCI signaling to derepress SIRT4 on glutamate dehydrogenase(GDH).Meanwhile,this crosstalk network could impede the efficacy of immunotherapy through mTORCI-P70S6K dependent PD-L1 production and PD-L1^(+)exosomes activity.In conclusion,our study highlights the non-coding regulatory role of HMGB1 with implicatio ns for RNA-based therapeutic targeting together with a predictio n of an ti-PD-L1 immuno therapy in HCC.Yanping Wei Xuewu Tang Yibin Ren Yun Yang Fengliang Song Jingbo Fu Shuowu Liu Miao Yu Jing Chen Suyang Wang Kecheng Zhang Yexiong Tan Zhipeng Han Lixjn Wei Baohua Zhang Zhangjun Cheng Liang Li Hongyang Wang 2022Signal Transduction and Targeted Therapy2022,7,1:0
20Time difference based measurement of ultrasonic cavitations in wastewater treatment显示文摘Intensity of cavitation is significant in ultrasonic wastewater treatment,but is complicated to measure.A time difference based method of ultrasonic cavitation measurement is proposed.The time differences at different powers of 495 kHz ultrasonic are measured in experiment in comparison with conductimetric method.Simulation results show that time difference and electrical conductivity are both approximately positive proportional to the ultrasonic power.The degradation of PNP solution verifies the availability in wastewater treatment by using ultrasonic.朱昌平 Wang Bin Liu Changwei Gong Runhang Liu Jing Ren Qinggong Han Qingbang Huang Bo Shan Minglei Tang Yibin Ni Caihua 2016High Technology Letters2016,22,1:0
