针对空间矢量脉宽调制(SVPWM)过调制算法复杂且涉及除法运算的问题,构建一种分裂式可变调制波,该调制波在调制度M∈[0,1]的线性区为正弦波,在M∈(1,4/π)的过调制区则分裂为两种以不同方式变化的正弦曲线段,相衔接构成一种调制波,其面积随M提升进一步扩大,直至方波。采用三角载波采样,在线性区改变调制波幅值即可线性地改变PWM基波值,在过调制区则减小两种正弦波曲线段间的分界角,继续提高PWM基波幅值大小,直至方波模式。经研究过调制区的PWM谐波影响与分界角初值的关系,得出最佳分界角初值。提出的PWM算法简单,线性区间的PWM电流总谐波畸变率(THD)与正弦脉宽调制(SPWM)一致;在M∈(1,1.2]过调制区其值仍延续低位。实验结果验证了该技术的有效性和优越性。

Chemicals possessing reactive electrophiles can denature innate proteins leading to undesired toxicity,and the overdose-induced liver injury by drugs containing electrophiles has been one of the major causes of non-approval and withdraw by the US Food and Drug Administration(FDA).Elucidating the associated proteins could guide the future development of therapeutics to circumvent these drugs’toxicities,but was largely limited by the current probing tools due to the steric hindrance of chemical tags including the common“click chemistry”*** the widely used non-steroidal anti-inflammatory drug acetaminophen(APAP)as an example,we hereby designed and synthesized an APAP analogue using fluorine as a steric-free *** toxicity studies indicated our analogue has similar activity to the parent *** analogue was applied to the mouse hepatocellular proteome together with the corresponding desthiobiotinSH probe for subsequent fluorine-thiol displacement reactions(FTDRs).This set of probes has enabled the labeling and pull-down of hepatocellular target proteins of the APAP metabolite as validated by Western *** preliminary validation results supported the interaction of APAP with the thioredoxin protein,which is an important redox protein for normal liver *** results demonstrated that our probes confer minimal steric perturbation and mimic the compounds of interest,allowing for global profiling of interacting *** fluorine-thiol displacement probing system could emerge as a powerful tool to enable the investigation of drug-protein interactions in complex biological environments.

Purpose–This paper aims to propose a train timetable rescheduling(TTR)approach from the perspective of multi-train tracking optimization based on the mutual spatiotemporal information in the high-speed railway signaling ***/methodology/approach–Firstly,a single-train trajectory optimization(STTO)model is constructed based on train dynamics and operating *** train kinematics parameters,including acceleration,speed and time at each position,are calculated to predict the arrival times in the train timetable.A STTO algorithm is developed to optimize a single-train time-efficient driving ***,a TTR approach based on multi-train tracking optimization(TTR-MTTO)is proposed with mutual *** constraints of temporary speed restriction(TSR)and end of authority are decoupled to calculate the tracking trajectory of the backward tracking *** multi-train trajectories at each position are optimized to generate a timeefficient train ***–The numerical experiment is performed on the Beijing-Tianjin high-speed railway line and *** STTO algorithm predicts the train’s planned arrival time to calculate the total train delay(TTD).As for the TSR scenario,the proposed TTR-MTTO can reduce TTD by 60.60%compared with the traditional TTR approach with dispatchers’***,TTR-MTTO can optimize a time-efficient train timetable to help dispatchers reschedule trains more ***/value–With the cooperative relationship and mutual information between train rescheduling and control,the proposed TTR-MTTO approach can automatically generate a time-efficient train timetable to reduce the total train delay and the work intensity of dispatchers.

林恩·埃里克森建立的“知识的结构”模型,很好地解释了以“大概念”组织单元的原理和机制。该模型分两个层面:第一层面是事实性知识,有“事实”和“主题”两个层级;第二层面是概括性知识,主要有“概念”和“概括性理解”两个层级。在教学中需依赖具体的事实性知识去发现或获得某一概念,经由理解某一概念构成一种“概念性视角”,凭借“概念性视角”去处理相应主题的具体事实。在两个层面相互作用的认知探究过程中,建立某一概念与其他概念的联系。“概念性理解”就是“由事实性实例支撑的真理”,可称为“概括性知识”。从学习内容的角度,“大概念”实际上是跨学科或学科“核心的概括性知识”。
