由此可见,集中/分布单元CU/DU(Centralized Unit/Distributed Unit)架构是研究C-RAN的基础。 本文结合运营商的基本需求和3GPP讨论结果,来简单分析CU/DU架构的特点和实现方式。 1.CU和DU逻辑功能分离的需求 目前,5G RAN架构考虑采用中央单元(CU)和分布单元(DU)独立部署的方式,以更好地满足各场景和应用的需求。这在...
Copper is an essential element in various biological processes, copper deficiency can reduce blood vessel elasticity and increase platelet aggregation, thereby increasing the risk of ischemic vascular disease; however, excess copper ions can lead to cytotoxicity, trigger cell death, and ultimately result ...
Surgical retrieval of an extrauterine IUD is advised by the FFPRHC.6The scientific literature strongly recommends removal of an extrauterine IUD even if its migration has not given rise to any clinical symptoms.IUDs in the abdomen, especially copper-containing ones,can result in the development of...
Labomed Inc., USA). The suspension solution was diluted based on the suspension to a solvent dilution ratio of 1:6. The 4.0 ml diluted suspension was then pipetted into the quartz cell for the test. Prior to the test, a baseline measurement was...
10. The presence of ZrO2could also enhance the copper dispersion as well as the surface basicity, which should strongly affect the CO2adsorption and methanol selectivity11,12. As a result, the Cu–ZnO–ZrO2(CZZ) system has gained an increasing interest for its outstanding activity1,8,9,11,...
Si(111)-(7 × 7) surfaces with deposits of noble metals form ordered overlayers after annealing. Coverages in the monolayer range of Ag and Au result in ( 3 × 3 )R30° overlayer structures and for Cu a pseudo "(5 × 5)" structure is produced, while at higher coverage of Au a (...
Through finite element studies, it is observed that the insertion bonding technique result in significantly larger plastic deformation in comparison to the conventional bonding technique under the same bonding conditions. Experimental studies of the insertion bonding technique were performed and it is ...
DO LARGE EARNINGS SURPRISES RESULT FROM MANIPULATION? RESEARCHERS Paul Griffin of the University of California, Davis, and David Lott of the University of Otago in New Zealand believe that the increasing empha... CC Verschoor - 《Strategic Finance》 被引量: 0发表: 2018年 Analysis of international...
This is the result of a new buffer management and heuristics in the cuBLAS library. As described in Results Reproducibility, numerical results may not be deterministic when cuBLAS APIs are launched in more than one CUDA stream using the same cuBLAS handle. This happens when two buffer sizes (...
(~11 nm; estimated from the XRD data; Supplementary Table1). The smaller mean grain sizes of the derived Cu relative to those of the parent materials could be attributed to the combined effect of the volume shrinkage of the unit-cell and crystal fragmentation7. We therefore concluded that...
