1Quasi-real-time simulation of rotating drum using discrete element method with parallel GPU computing显示文摘Real-time simulation of industrial equipment is a huge challenge nowadays. The high performance and fine-grained parallel computing provided by graphics processing units (GPUs) bring us closer to our goals. In this article, an industrial-scale rotating drum is simulated using simplified discrete element method (DEM) without consideration of the tangential components of contact force and particle rotation. A single GPU is used first to simulate a small model system with about 8000 particles in realtime, and the simulation is then scaled up to industrial scale using more than 200 GPUs in a 1D domain-decomposition parallelization mode. The overall speed is about 1/11 of the real-time. Optimization of the communication part of the parallel GPU codes can speed up the simulation further, indicating that such real-time simulations have not only methodological but also industrial implications in the near future.Ji Xu Huabiao Oi Xiaojian Fang Liqiang Lu Wei Ge Xiaowei Wang Ming xu Feiguo Chen xianfeng He Jinghai Li 2011Particuology2011,9,4:16

3田间行走式测定的红外光谱数据与土壤质地之间的相关性研究显示文摘近红外光谱是利用漫反射来分析物质的某些化学性质,已在农业及其他许多领域得到广泛应用。尽管在实验室条件下,研究证明可以应用近红外光谱分析技术来快速、方便地测定土壤参数,但在田间大范围内应用红外光谱快速测定来分析土壤性质,仍然缺乏研究;该研究以田间行走式设备获取的红外光谱数据为基础,分析和比较了不同数据处理技术下红外光谱信息与土壤质地之间的相关性,发现应用基于算术运算的波段组合技术可以明显地提高红外光谱信息与土壤质地之间的相关性,为田间光谱数据的分析处理与应用提供了依据。沈掌泉 Oi Jiaguo Huang Xuewen 单英杰 王珂 2009光谱学与光谱分析2009,29,6:11
4Hypoxia increases adipogenesis and affects adipocytokine production in orbital fibroblasts-a possible explanation of the link between smoking and Graves' ophthalmopathy显示文摘AIM:To assess the effects of hypoxia on human orbital fibroblasts(OF)on adipogenesis and adipocytokine production.METHODS:Human OF were derived from tissues obtained from patients with Graves'ophthalmopathy(GO)and from patients without known thyroid diseases undergoing blepharoplasty.The OF were cultured separately under normoxic and hypoxic conditions.Comparisons of adipocytokine concentrations using multiplex ELISA and lipid accumulation in the cells using Oil Red O staining were subsequently performed.RESULTS:There was increased adipogenesis in OF from GO subject when exposed to hypoxic culture conditions.This was not observed in OF from normal controls.Hypoxia led to an increase in leptin and a decrease in MCP-1 secretion in OF cultures.CONCLUSION:Hypoxia induces adipogenesis in OF and may represent a mechanism by which smoking contributes to deterioration of GO.We also found novel changes to leptin and MCP-1 production in OF cultures exposed to hypoxia suggesting important roles of these cytokines in the disease process.Chiaw Ling Chng Oi Fah Lai Charmaine Sze-Min Chew Yu Pei Peh Stephanie Man-Chung Fook-Chong Lay Leng Seah Daphne Hsu-Chin Khoo 2014International Journal of Ophthalmology(English edition)2014,7,3:10

7Improving the electrical performance of resistive switching memory using doping technology显示文摘In this paper, improvements of resistive random access memory (RRAM) using doping technology are summarized and analyzed. Based on a Cu/ZrO2/Pt device, three doping technologies with Ti ions, Cu, and Cu nanocrystal, respectively, are adopted in the experiments. Compared to an undoped device, improvements focus on four points: eliminating the electroforming process, reducing operation voltage, improving electrical uniformity, and increasing device yield. In addition, thermal stability of the high resistance state and better retention are also achieved by the doping technology. We demonstrate that doping technology is an effective way of improving the electrical performance of RRAM.WANG Yan LIU Oi LU HangBing LONG ShiBing WANG Wei LI YingTao ZHANG Sen LIAN WenTai YANG JianHong LIU Ming 2012Chinese Science Bulletin2012,57,11:6

10Ultrasonic Plasma Engineering Toward Facile Synthesis of Single-Atom M-N4/N-Doped Carbon(M=Fe,Co) as Superior Oxygen Electrocatalyst in Rechargeable Zinc-Air Batteries显示文摘As bifunctional oxygen evolution/reduction electrocatalysts,transition-metal-based single-atom-doped nitrogen-carbon(NC)matrices are promising successors of the corresponding noblemetal-based catalysts,offering the advantages of ultrahigh atom utilization effciency and surface active energy.However,the fabrication of such matrices(e.g.,well-dispersed single-atom-doped M-N4/NCs)often requires numerous steps and tedious processes.Herein,ultrasonic plasma engineering allows direct carbonization in a precursor solution containing metal phthalocyanine and aniline.When combining with the dispersion effect of ultrasonic waves,we successfully fabricated uniform single-atom M-N4(M=Fe,Co)carbon catalysts with a production rate as high as 10 mg min-1.The Co-N4/NC presented a bifunctional potential drop ofΔE=0.79 V,outperforming the benchmark Pt/C-Ru/C catalyst(ΔE=0.88 V)at the same catalyst loading.Theoretical calculations revealed that Co-N4 was the major active site with superior O2 adsorption-desorption mechanisms.In a practical Zn-air battery test,the air electrode coated with Co-N4/NC exhibited a specific capacity(762.8 mAh g(-1))and power density(101.62 mW cm^(-2)),exceeding those of Pt/C-Ru/C(700.8 mAh g^(-1) and 89.16 mW cm^(-2),respectively)at the same catalyst loading.Moreover,for Co-N4/NC,the potential difference increased from 1.16 to 1.47 V after 100 charge-discharge cycles.The proposed innovative and scalable strategy was concluded to be well suited for the fabrication of single-atom-doped carbons as promising bifunctional oxygen evolution/reduction electrocatalysts for metal-air batteries.Kai Chen Seonghee Kim Minyeong Je Heechae Choi Zhicong Shi Nikola Vladimir Kwang Ho Kim Oi Lun Li 2021Nano-Micro Letters2021,13,4:4
11Color Correction for Multi-view Video Using Energy Minimization of View Networks显示文摘Systems using numerous cameras are emerging in many fields due to their ease of production and reduced cost,and one of the fields where they are expected to be used more actively in the near future is in image-based rendering(IBR).Color correction between views is necessary to use multi-view systems in IBR to make audiences feel comfortable when views are switched or when a free viewpoint video is displayed.Color correction usually involves two steps:the first is to adjust camera parameters such as gain,brightness,and aperture before capture,and the second is to modify captured videos through image processing.This paper deals with the latter,which does not need a color pattern board.The proposed method uses scale invariant feature transform(SIFT) to detect correspondences,treats RGB channels independently,calculates lookup tables with an energy-minimization approach,and corrects captured video with these tables.The experimental results reveal that this approach works well.Kenji Yamamoto Ryutaro Oi 2008International Journal of Automation and computing2008,5,3:4

18Tissue Extracts From Infarcted Myocardium of Rats in Promoting the Differentiation of Bone Marrow Stromal Cells Into Cardiomyocyte-like Cells显示文摘Objective To investigate whether cardiac tissue extracts from rats could mimic the cardiac microenvironment and act as a natural inducer in promoting the differentiation of bone marrow stromal cells (BMSCs) into cardiomyocytes. Methods Three kinds of tissue extract or cell lysate [infarcted myocardial tissue extract (IMTE), normal myocardial tissue extract (NMTE) and cultured neonatal myocardial lysate (NML)] were employed to induce BMSCs into cardiomyocyte-like cells. The cells were harvested at each time point for reverse transcription-polymerase chain reaction (RT-PCR) detection, immunocytochemical analysis, and transmission electron microscopy. Results After a 7-day induction, BMSCs were enlarged and polygonal in morphology. Myofilaments, striated sarcomeres, Z-lines, and more mitochondia were observed under transmission electron microscope. Elevated expression levels of cardiac-specific genes and proteins were also confirmed by RT-PCR and immunocytochemistry. Moreover, IMTE showed a greater capacity of differentiating BMSCs into cardiomyocyte-like cells. Conclusions Cardiac tissue extracts, especially IMTE, can effectively differentiate BMSCs into cardiomyocyte-like cells.XIAO-NING LIU Oi YIN HAO ZHANG HONG ZHANG SHEN-JUN ZHU YING-Jie WEI SHENG-SHOU HU 2008Biomedical and Environmental Sciences2008,21,2:2
