Green plants provide the foundation for the structure, function, and interactions among organisms in both tropical and temperate zones. To date, many investigations have revealed patterns and mechanis...
Timestamping is an important cryptographic primitive with numerous applications. The availability of a decentralized blockchain such as that offered by the Bitcoin protocol offers new possibilities to...
Era-Interim (ECMWF Re- analysis) is a global reanalysis atmospheric product which is being continuously updated in real time since 1979. It is also termed as third generation reanalysis product. The E...
ERA方法是基于环境激励的结构振动测试的方法中重要的时域分析方法。主要由ERA算法对齐齐哈尔砌体结构居民房的基本模态参数进行测试。简述了ERA算法的主要思路和计算过程,介绍了相应的模态识别准则MAC,以及ERA算法在MATLAB中的实现。由ERA算法得到的模态参数与有限元建模分析结果分析比较吻合,为砌体结构在环境激励下用ERA方法测试模态参数提供了实验依据。最后,讨论了ERA方法与有限元建模分析结...
Consensus (a.k.a. Byzantine agreement) is arguably one of the most fundamental problems in distributed systems, playing also an important role in the area of cryptographic protocols as the enabler of ...
Antimicrobials enable modern medicine, but their efficacy is a limited resource. In the past 20 years, antimicrobial development has slowed dramatically while antimicrobial resistance continues to ris...
As precision medicine research and its clinical applications continue to advance, it is critical for pharmacists to be involved in these developments to deliver optimal, tailored drug therapies for pa...
China's global shipping connectivity had been somewhat overlooked as the bulk of related studies predominantly focused on the throughput volume of its own port cities. This article tackles such lacuna...
In the last decade a significant number of projects and programmes in different domains of Earth Observation and environmental monitoring have generated a substantial amount of data and knowledge on d...
研究了基于时域缩放选带,使用振动模态特征系统实现算法(eigensystem realization algorithm,ERA)的工作模态辨识技术。分析了ERA环境激励模态辨识方法的理论,给出了时域缩放选带技术和真实模态挑选技术的方法以及工作流程。通过算例研究了采用时域缩放技术的ERA工作模态辨识方法。研究结果表明:使用该方法可以有效地辨识出结构的模态,且可以采用滑动时间窗的方法获得模态随时间的...
Since the end of the cold war, especially since the 9/11, religion’s importance has risen sharply in international relations. It has already become an inevitable and important factor in the strate...
One of the crucial factors for enabling fast and secure computations in the Zettabyte era is the use of incremental cryptographic primitives. For files ranging from several megabytes up to hundreds ...
Cyber technologies are becoming an increasingly important part of all facets of our lives. Consequently, cybersecurity is a fundamental and growing part of what it means for us to be safe. One of the...
Advances in nucleic acid sequencing technology are removing obstacles that historically prevented use of genomics within ocean change biology. As one of thefirst marine calcifiers to have ...
The purpose of this article is to examine how and to what extent schools’ responses to accountability policies in the United States influence the ability of new teachers of color to draw on their own ...
