| 2 | Research progress in rehabilitation treatment of stroke patients A bibliometric analysis显示文摘BACKGROUND: Stroke presents as a transient or chronic brain dysfunction and is associated with high morbidity and high mortality. The doctors and scientists would like to argue how to enhance the validity of the rehabilitation treatment and how to further improve the level of treatment on stroke. OBJECTIVE: The aim of this study was to quantitatively analyze the current worldwide progress in research on stroke rehabilitation treatment based on Web of Science database and ClinicalTrial.gov in the past 10 years. METHODS: We conducted a quantitative analysis of clinical trial articles regarding stroke rehabilitation published in English from 2003 to 2013 and indexed in the National Institutes of Health Clinical Trials registry and Web of Science databases. Data were downloaded on March 15, 2013. RESULTS: (1) From 2003 to 2013, 2 654 clinical trials investigating stroke were indexed in ClinicalTrials.gov. There were only 58 clinical trials registered in 2003, and there was a marked increase from 2005. A total of 605 clinical trials on the rehabilitation of stroke were conducted in the past 10 years. (2) The analysis showed that most of the trials in the field were registered by North American institutions. With respect to the Asian countries, China and Taiwan Region of China also published a reasonable proportion of the trials, but comparatively speaking, the number of trials is really rare. Most of the interventions were drugs, followed by the devices, and behavioral interventions were ranked third. (3) In the past 10 years, there were 4 052 studies on stroke indexed by Web of Science database. CONCLUSION: From perspective of research progress, we found that the number of clinical trials and papers on stroke rehabilitation has increased significantly in the past 10 years, between them a remarkable positive correlation exists. | Xiaodong Feng Chengmei Liu Qingchuan Guo Yanjie Bai Yafeng Ren Binbin Ren Junmin Bai Lidian Chen | 2013 | Neural Regeneration Research2013,8,15: | 3 |
| 3 | Hydrogen storage of multiwalled carbon nanotubes coated with Pd-Ni nanoparticles under moderate conditions显示文摘A type of novel material with a high hy-drogen storage capacity was prepared by supporting PdNi18 alloy nanoparticles,which were synthesized by using a new colloid method,on the surface of pretreated multiwalled carbon nanotubes (MWCNTs). The average PdNi18 alloy particle sizes calculated from XRD patterns were ca. 3 nm,and the high dis-persion of these particles on MWCNTs was con-firmed by TEM image. Hydrogen storage perform-ance of the composite was investigated under mod-erate pressure (0.1―1.5 MPa) at room temperature,and a maximum storage capacity of ca. 2.3 wt% was achieved under 1.5 MPa at room temperature,which was much higher than that reported previously under the same conditions. | REN Jianwei LIAO Shijun LIU Junmin | 2006 | Chinese Science Bulletin2006,51,24: | 2 |
| 4 | Experimental research on oil fi lm thickness and its microwave scattering during emulsifi cation显示文摘Synthetic Aperture Radar(SAR) plays a major role in identifying oil spills on the sea surface.However,obtaining information of oil spill thickness(volume) is still a challenge.Emulsification is an important process affecting the thickness and normalized radar cross section(NRCS) of oil film.Experiments of crude oil emulsification with C-band fully-polarized scatterometer were conducted combining airborne hyperspectral imaging spectrometer and 3 D laser scanner observation data,to provide experimental parameters and method to support accurate remote sensing monitoring on marine oil spill.It is further proved that through quantitative homogeneous emulsified oil spill experiments,to a certain extent,the NRCS of oil film increased during the emulsification process of crude oil.The backscattering mechanism of crude oil emulsification was explored using a semi-empirical model(SEM);the change of oil film NRCS was modulated by its dielectric constant and surface roughness,in which the dielectric constant showed a dominant effect.The relationship between thickness and NRCS of oil film was studied under two experimental conditions.The differences of NRCS between oil film and adjacent seawater(Δσ~0) and the damping ratio(DR) were found to have a linear relationship with oil thickness,which were best in the vertical polarization mode(VV) at 45° incident angle during the quantitative crude oil homogeneous emulsification process.In the natural emulsification process of continuous oil spill in which oil film was mixed with both crude oil and emulsified oil,an empirical equation of oil film thickness is preliminarily established.The Δσ~0,DR,and the empirical equation of oil film thickness were applied to the marine continuous oil spill incident on a 19-3 oil platform with spaceborne SAR image and successfully explained the distribution of the relative thickness of the oil film. | Jie GUO Chenqi XU Genwang LIU Xi ZHANG Junmin MENG Guangbo REN | 2022 | Journal of Oceanology and Limnology2022,40,4: | 2 |
| 5 | 低伽马火山岩岩性测井识别——以准噶尔盆地中拐凸起石炭系为例显示文摘准噶尔盆地中拐凸起石炭系火山岩岩性复杂多样、横向变化快、纵向厚度大,岩性识别和多井对比困难;石炭系火山岩(包括酸性岩)均呈低GR特征,利用GR无法准确识别岩性。运用岩心标定测井,利用ECS测井进行成因、成分分析选取敏感矿物建立交会图进行火山岩化学成分划分,结合电成像测井反映的结构构造信息建立成像模式图版进一步从结构山对岩性进行识别;在特殊测井识别岩性的基础上,分析不同岩性、不同结构及矿物成分的火山岩常规测井相应特征,将特殊测井识别结果推广到常规测井中,进行常规曲线敏感性分析,建立中子-密度交会图,从而实现利用常规测井曲线划分火山岩岩性。 | 李静 Yang Disheng Ren Junmin | 2015 | 国外测井技术2015,0,4: | 1 |
| 6 | MNi_(4.8)Sn_(0.2)(M=La, Nd)-supported multi-walled carbon nanotube composites as hydrogen storage materials显示文摘Two composites LaNi4.8Sn0.2/CNTs and NdNi4.8Sn0.2/CNTs were prepared by an impregnation-reduction method. Their hydrogen storage capacity could reach up to 2.96 wt% and 2.88 wt% respectively at room temperature and 1.0 MPa pressure. These values, which might result from the synergetic effect between the alloy nanoparticles and the pretreated CNTs, were three times higher than those of the unsupported MNi4.8Sn0.2 (M=La, Nd) alloys under the same conditions. XRD and TEM revealed that the alloy particles were uniformly dispersed on the CNTs and the average particle size was ca. 30 nm. The composites also showed good stability and the hydrogen storage capacity decreased by less than 6% after 100 adsorption-desorption cycles. Moreover, no noticeable change in crystalline structure was observed for the composites. | REN JianWei LIAO ShiJun LIU JunMin | 2007 | Chinese Science Bulletin2007,52,12: | 1 |

| 8 | Neural network-based surrogate model for inverse design of metasurfaces显示文摘Metasurfaces composed of spatially arranged ultrathin subwavelength elements are promising photonic devices for manipulating optical wavefronts,with potential applications in holography,metalens,and multiplexing communications.Finding microstructures that meet light modulation requirements is always a challenge in designing metasurfaces,where parameter sweep,gradient-based inverse design,and topology optimization are the most commonly used design methods in which the massive electromagnetic iterations require the design computational cost and are sometimes prohibitive.Herein,we propose a fast inverse design method that combines a physicsbased neural network surrogate model(NNSM)with an optimization algorithm.The NNSM,which can generate an accurate electromagnetic response from the geometric topologies of the meta-atoms,is constructed for electromagnetic iterations,and the optimization algorithm is used to search for the on-demand meta-atoms from the phase library established by the NNSM to realize an inverse design.This method addresses two important problems in metasurface design:fast and accurate electromagnetic wave phase prediction and inverse design through a single phase-shift value.As a proof-of-concept,we designed an orbital angular momentum(de)multiplexer based on a phase-type metasurface,and 200 Gbit/s quadrature-phase shift-keying signals were successfully transmitted with a bit error rate approaching 1.67×10^(-6).Because the design is mainly based on an optimization algorithm,it can address the“one-to-many”inverse problem in other micro/nano devices such as integrated photonic circuits,waveguides,and nano-antennas. | GUOQING JING PEIPEI WANG HAISHENG WU JIANJUN REN ZHIQIANG XIE JUNMIN LIU HUAPENG YE YING LI DIANYUAN FAN SHUQING CHEN | 2022 | Photonics Research2022,10,6: | 0 |
