| 1 | AoA-Based Channel Estimation for Massive MIMO OFDM Communication Systems on High Speed Rails显示文摘Channel estimation is a well-known challenge for wireless orthogonal frequency division multiplexing(OFDM)communication systems with massive antennas on high speed rails(HSRs).This paper investigates this problem and design two practicable uplink and downlink channel estimators for orthogonal frequency division multiplexing(OFDM)communication systems with massive antenna arrays at base station on HSRs.Specifically,we first use pilots to estimate the initial angle of arrival(AoA)and channel gain information of each uplink path through discrete Fourier transform(DFT),and then refine the estimates via the angle rotation technique and suggested pilot design.Based on the uplink angel estimation,we design a new downlink channel estimator for frequency division duplexing(FDD)systems.Additionally,we derive the Cramér-Rao lower bounds(CRLBs)of the AoA and channel gain estimates.Finally,numerical results are provided to corroborate our proposed studies. | Yanrong Zhao Wenjing Zhao Gongpu Wang Bo Ai Hervin Hidayat Putra Bagus Juliyanto | 2020 | China Communications2020,17,3: | 6 |
| 2 | Serum testosterone and prostate-specific antigen levels are major risk factors for prostatic volume increase among benign prostatic hyperplasia patients显示文摘Objective:Benign prostatic hyperplasia(BPH)is one of the most common diseases found among elderly men.Even though multiple risk factors of BPH have been identified in the past,the risk factors which have a direct impact on prostate volume have not been identified.In this study,we aim to determine the most significant contributing risk factors to prostate volume enlargement by analyzing possible associated risk factors previously studied.Methods:This is a quantitative study with an analytical observational design,performed using a retrospective cohort approach.Total sampling was performed on 83 patients who underwent transurethral resection of the prostate(TURP)in Sanglah General Hospital from January to February 2019.Bivariate analysis is performed to examine each variable's association with prostate volume followed by a multivariate analysis.All variables were reassessed with path analysis to measure the direct effects,indirect effects,and total effects on prostate volume.Results:Bivariate analysis shows that serum testosterone(R=0.208;p=0.059)and prostate-specific antigen(PSA)level(R=0.626;p=0.001)have a significant association with prostate volume.Multivariate analysis shows that serum PSA(B=1.4;p=0.001;95%confidence interval[95%CI]=1.039-1.770)and testosterone(B=0.024;p=0.005;95%CI=0.008-0.041)levels are significant among all the analyzed risk factors.There is a significant and strong effect of PSA to prostate volume(c=0.636;p=0.001)whereas testosterone has a significant albeit weak effect to prostate volume(c=0.246;p=0.009)based on the total effect of the path analysis.Conclusion:Serum testosterone and PSA levels are significantly associated with prostatic volume increase among BPH patients. | Gede Wirya Kusuma Duarsa Yudit Anastasia Sari Anak Agung Gde Oka Kadek Budi Santosa I Wayan Yudiana Pande Made Wisnu Tirtayasa Ida Bagus Putra Pramana Yudhistira Pradnyan Kloping | 2021 | Asian Journal of Urology2021,8,3: | 3 |
| 3 | 花生“一拌三喷”绿色防控技术示范效果显示文摘为探索花生不同生育阶段的最佳植保解决方案,于2019—2020年进行了“一拌三喷”绿色防控技术示范。结果表明,29%噻虫·咯·霜灵悬浮种衣剂拌种后,能够有效提高花生出苗率,示范区出苗率75.0%,较常规区和对照区增幅分别为17.1%和27.9%,差异显著;同时还可减少根部病害的发生,未发生茎基腐病。示范区出苗齐,主根粗壮,侧根数量多(162根/株),示范区与常规区和对照区差异显著。200 g/L氟酰羟·苯甲唑悬浮剂对花生叶斑病防效显著(94.7%),示范区花生落叶少,叶斑病病情指数仅为2.6,防效显著优于常规区和对照区。花生产量显著提高,示范区两年平均单产达到332.8 kg/667m^(2),较对照区和常规区分别增加107.7 kg和31.6 kg,增产幅度达到47.8%和10.5%。采用“一拌三喷”绿色防控技术,示范区平均比对照区净增收入534元/667m^(2),比常规区净增收入206元/667m^(2),经济效益显著。建议在花生种植区域大面积推广应用以29%噻虫·咯·霜灵悬浮种衣剂拌种、200 g/L氟酰羟·苯甲唑悬浮剂叶面喷雾为主的“一拌三喷”花生绿色防控技术。 | 陈芳龙 曲诚怀 王秀连 迟玉成 Ida Bagus Andika 曹欣然 | 2022 | 中国植保导刊2022,42,2: | 3 |
| 4 | Comparison of Microbubble and Air Layer Injection with Porous Media for Drag Reduction on a Self-propelled Barge Ship Model显示文摘Ship resistance issues are related to fuel economy,speed,and cost efficiency.Air lubrication is a promising technique for lowering hull frictional resistance as it is supposed to modify the energy in the turbulent boundary layer and thereby reduce hull friction.In this paper,the objective is to identify the optimum type of air lubrication using microbubble drag reduction(MBDR)and air layer drag reduction(ALDR)techniques to reduce the resistance of a 56-m Indonesian self-propelled barge(SPB).A model with the following dimensions was constructed:length L=2000 mm,breadth B=521.60 mm,and draft T=52.50 mm.The ship model was towed using standard towing tank experimental parameters.The speed was varied over the Froude number range 0.11–0.31.The air layer flow rate was varied at 80,85,and 90 standard liters per minute(SLPM)and the microbubble injection coefficient over the range 0.20–0.60.The results show that the ship model using the air layer had the highest drag reduction up to a maximum of 90%.Based on the characteristics of the SPB,which operates at low speed,the optimum air lubrication type to reduce resistance in this instance is ALDR. | Yanuar Kurniawan T.Waskito Sigit Y.Pratama Bagus D.Candra Bilmantasya A.Rahmat | 2018 | Journal of Marine Science and Application2018,17,2: | 3 |
| 5 | Hernia mesh prevent dislocation after wide excision and reconstruction of giant cell tumor distal radius显示文摘Giant cell tumor(GCT) remains as major health problem. GCT which located at the lower end of the radius tends to be more aggressive. Wide excision and reconstruction of the wrist in stage 3 of distal radius GCT lesion is an optimal modality to prevent tumor recurrence. However, dislocation often occurs as its complication. We are reporting patient with GCT of distal radius treated with wide excision and reconstruction using nonvascularized fibular graft and the addition of hernia mesh. Circumferential non-absorbable polypropylene hernia mesh was applied, covered radioulnar joint and volar aspect of radius, and served as additional support to prevent dislocation. During five years and two months of follow-up, we found no dislocation in our patient. Furthermore, good functional outcome was obtained. Our finding suggests that the addition of hernia mesh after wide excision and reconstruction with nonvascularized fibular graft may benefit to prevent dislocation and provides an excellent functional outcome. | I Gede E Wiratnaya I Gusti Bagus Arie M Budiartha I Gusti Ngurah Y Setiawan Dwijo A Sindhughosa I Ketut S Kawiyana Putu Astawa | 2017 | World Journal of Orthopedics2017,8,9: | 3 |
| 6 | 提取樱桃中植物病毒RNA方法的建立与优化显示文摘RNA提取是现代分子生物学中的一项常用技术,是后续试验的基础。樱桃样品中富含大量的糖类和酚类物质,同时富含降解RNA酶,为提取高质量的RNA带来了极大的困难。为探寻能够提取樱桃中高质量RNA以满足Northern Blot等分子实验的要求,对近年来国内外常用的RNA提取方法进行了筛选和归纳,进行优化并同商品化试剂盒进行了比较和评价分析。结果表明:尽管适用于樱桃RNA提取的方法有很多,但其在提取樱桃总RNA的效果各有不同,试剂盒B提取的RNA质量好,改良SDS法可以提取出纯度高且量大的樱桃总RNA,改良CTAB法次之。 | 刘杰 于成明 陈芳龙 郭静静 IDA BAGUS ANDIKA 曹欣然 | 2021 | 山东农业大学学报(自然科学版)2021,52,6: | 2 |
