实时操作系统RTOS能够满足精确的实时性要求和提供良好的稳定性,线程信号作为RTOS的同步与通信手段之一,常用于协同任务间或任务与中断间的工作。本文通过深入剖析RTOS的线程信号作用、响应机制以及关键技术要素,提出了基于printf输出的线程信号过程分析方法,给出了Mbed OS的调度策略。以NXP的KL36芯片为例,对Mbed OS的线程信号进行了实践和响应时间分析,直观输出了线程响应线程信号的调度过程信息,并对调度时序进行了梳理与剖析,从微观层面上展示了Mbed OS的线程信号响应机制,为更好地分析其

生态风险评价的目的是采取应对措施,减少风险灾害造成的损失。城市建设前的规划评估阶段进行生态风险评估非常重要,如何通过生态风险评价确定城市建设开发的核心区、拓展区以及其他功能分区的空间位置,规避可能发生的生态风险一直是城市生态规划的核心内容之一。本文以京津冀核心区的雄安地区为研究对象,采用风险因子识别、风险等级划分和风险指数评估的方法,基于Arc GIS平台及其空间分析工具,确定了暴雨、洪涝、工程地质灾害等生态风险空间分布特征,并据此结合河流、湖泊分布,提出了雄安地区城市核心区、拓展区、协调区、限建区、禁建
Use of a non-zero hydrologic response unit(HRU) threshold is an effective way of reducing unmanageable HRU numbers and simplifying computational cost in the Soil and Water Assessment Tool(SWAT) hydrologic modelling. However, being less representative of w
Epigenetic modifications within promoter sequences can act as regulators of gene expression.Shoot regeneration is influenced by both DNA methylation and histone methylation,but the mechanistic basis of this regulation is obscure.Here,we identified 218 gen
Trichomes function in plant defenses against bi-otic and abiotic stresses;examination of glabrous lines, which lack trichomes, has revealed key as-pects of tric
本文利用H2O2脱色、酶法和Sevage法联合脱蛋白对野巴子粗多糖进行初步纯化并得到初步纯化多糖(YBZp),对YBZp采用Superdex-75和Superdex-30串联凝胶柱进行进一步纯化,得到野巴子多糖(YBZb)。经高效凝胶渗透色谱法检测为均一的纯化多糖,分子量6 400.3 u。YBZb的结构鉴定采用甲基化、气相色谱、气相色谱-质谱、核磁共振、红外光谱方法。结果表明,YBZb的单糖组成为阿拉伯糖、甘露糖、葡萄糖、半乳糖,相对摩尔比为0.526:0.061:0.166:0.247,YBZb是由4
本文基于区域绿色创新多维度评价视角,选用粤闽浙沿海城市群13个城市2013年-2019年数据,分别运用基于规模效益分析需求的BCC模型、K均值聚类分析法、基于双边比较分析需求的Bilateral SBM模型和考虑了工业排放非期望产出约束的Undesired SBM模型,测度了粤闽浙沿海城市群在不同约束下的绿色创新效率,并进行了不同维度效率的可视化构图。结果表明,粤闽浙沿海城市群存在一定程度的绿色创新发展不均衡现象,群内城市出现了显著的发展层次差异,部分沿海工贸城市的绿色效率达到了较高发展水平,为群内城市树
Plants have a hierarchical circadian structure comprising multiple tissue-specific oscillators that operate at different speeds and regulate the expression of distinct sets of genes in different organs.However,the identity of the genes differentially regu
Protein phosphorylation and dephosphorylation have been reported to play important roles in plant cold responses.In addition,phospho-regulatory feedback is a conserved mechanism for biological processes and stress responses in animals and plants.However,i
In eukaryotes, histone acetylation is a major modification on histone N-terminal tails that is tightly connected to transcriptional activation. HDA6 is a histon
Copy number variations(CNVs), which can affect the role of long non-coding RNAs(lncRNAs), are important genetic changes seen in some malignant tumors. We analyzed lncRNAs with CNV to explore the relationship between lncRNAs and prognosis in bladder cancer
