《民谣》是王尧的一部回忆录式小说,从故乡的一座码头写起,讲述“我”的成长记忆,展现人们在时代变迁中不同的选择与命运。作品给读者带来了“非虚构感”的阅读体验,主要来源于真实的时空叙述和采取的第一人称叙述形式,使读者能够在阅读中真切感受到人物的行为与心境。围绕《民谣》的叙述声音解读,发现独特的叙述声音使作品具备了可读性,现场感、读者参与感、真实感三方面优势增强了作品的真实性和说服力。但在解读过程中,发现作品采取的第一人称叙述视角存在一定的局限性,不仅容易使作品立场变得单一,也容易影响读者的认知立场。

郁达夫小说充满浓重的悲剧与感伤色彩,这是其小说的一大特色。《沉沦》与《春风沉醉的晚上》两部作品中的主人公,作为近代社会的“零余者”,身上虽都具有浓浓的悲剧色彩,但又有所不同。前者主要展现的是青年知识分子的“欲”,后者则反映了爱情的“灵”而无欲望。而作为创作者的郁达夫,在文本内塑造这些“悲情”主人公的同时,在文本外的写作过程中也上演了“崇高”的悲剧。

电极材料是推进电池技术发展及应用的关键。作为锂离子电池正极材料的LiFePO4表现出优异的电池性能(大容量、优异循环特性),但也有本征低电导率的缺点。具有橄榄石结构的LiFePO4在电池充放电过程发生FePO4与LiFePO4之间的相变,已有实验证明充放电过程中出现固溶体LixFePO4。掺杂是提高材料电导率的常用手段,但LiFePO4的掺杂却一直饱受争议;缺陷化学的研究初步认定通过适当点缺陷的电荷补偿,晶体内引入掺杂元素是可以实现的,并且提出几种缺陷补偿机制。导电相复合可降低电极颗粒间的接触电阻,特别是LiFePO4的碳包覆有效地改善其电化学性能,促进其工业化推广;碳包覆的有效性取决于碳的sp2杂化键的比例及碳含量。由于电极材料形貌影响电池的充放电动力学过程,LiFePO4的颗粒尺寸、形状、表面粗糙度等的控制都成为提高电池性能的重要手段;LiFePO4的薄膜制备及三维构架技术则进一步推动微型电池的应用发展。

Recently,Peter et al reported a novel form of cell death(cuproptosis)that was different from other known death mechanisms.1 They found that accumulation of copper ions could induce destabilization of Fe-S cluster proteins and aggregation of mitochondrial lipoylated proteins,ultimately resulting in cuproptosis.1 of note,ten genes were identified as cuproptosis-related genes(CRGs)in copper ion-induced cell death,including PDHB,PDHA1,DLAT,DLD,LIPT1,LIAS,FDX1,CDKN2A,GLS,and MTF1.1 Since dysregulation of copper metabolism is involved in many cancers,cuproptosis and CRGs may play vital roles in cancer development and treatment.1.2 Herein,our pancancer analysis revealed the coordinated upregulation of 9 of 10 CRGs in human liver hepatocellular carcinoma(LIHC)across 33 solid tumors(Fig.S1A;Fig.1A),suggesting the distinct role of CRGs in *** then explored the genetic landscape,biological function,and clinical significance of CRGs in LIHC,and validated our bioinformatic findings by in vitro experiments and clinical *** detailed methods were described in the supplementary material.
