Recently,the rapid development of non-fullerene acceptors(NFAs)has laid the foundation for performance improvements in near-infrared(NIR)organic photodetectors(OPDs).However,reducing the bandgap of NFAs to achieve strong absorption in the shorter-wave region usually leads to increased dark current density(J_(d))and decreased responsivity(R),severely limiting the detectivity(D*)of *** date,it remains challenging to manipulate the J_(d) of NIR-OPDs through rational structure engineering of ***,three NIR-NFAs,namely bis(2-decyltetradecyl)4,4′-(2′,7′-di-tert-butylspiro[cyclopenta[2,1-b:3,4-b′]dithiophene-4,9′-fluorene]-2,6-diyl)bis(6-(((Z)-1-(dicyanomethylene)-5,6-difluoro-3-oxo-1,3-dihydro-2H-inden-2-ylidene)methyl)thieno[3,4-b]thiophene-2-carboxylate)(TSIC-4F),bis(2-decyltetradecyl)6,6′-(2′,7′-di-tert-butylspiro[cyclopenta[2,1-b:3,4-b′]dithiophene-4,9′-fluorene]-2,6-diyl)bis(4-(((Z)-1-(dicyanomethylene)-5,6-difluoro-3-oxo-1,3-dihydro-2H-inden-2-ylidene)methyl)thieno[3,4-b]thiophene-2-carboxylate)(STIC-4F),and 2,2′-((2Z,2′Z)-(((2′,7′-di-tert-butylspiro[cyclopenta[2,1-b:3,4-b′]dithiophene-4,9′-fluorene]-2,6-diyl)bis(2,3-bis(5-(2-butyloctyl)thiophen-2-yl)thieno[3,4-b]pyrazine-7,5-diyl))bis(metha-neylylidene))bis(5,6-difluoro-3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile(TPIC-4F),were designed using the thieno[3,4-b]thiophene(TT)and thieno[3,4-b]pyrazine(TPy)derivatives as theπ-*** to the intramolecular S-S and S-N interactions,STIC-4F and TPIC-4F exhibited smaller backbone distortions than TSIC-4F.A significantly red-shifted absorption with a peak at 1015 nm was observed in TPIC-4F film,larger than that(ca.960 nm)for TSIC-4F and STIC-4F ***,OPDs operating in a photovoltaic mode were successfully fabricated,and TPIC-4F-based OPDs achieved the lowest J_(d) of 3.18×10^(-8) A/cm^(2) at-0.1 ***,although TPIC-4F-based OPDs exhibited the lowest R,higher shot-noise-limited specific detectivity(D_(sh)*)in 1000-1200 nm co

目的探讨钙卫蛋白S100 A8/A9复合物在重症肺炎支原体肺炎(severe Mycoplasma pneumoniae pneumonia,SMPP)患儿病情评估中的作用。方法前瞻性纳入136例MPP患儿与30例健康对照儿童。根据病情严重程度,将MPP组患儿分为轻症亚组(n=40)和SMPP亚组(n=96)。比较两组及两亚组间S100 A8/A9复合物及相关炎症因子的水平差异,并分析S100 A8/A9在评估MPP严重程度中的作用。结果MPP组患儿S100 A8/A9显著高于健康对照组,其中SMPP组升高更显著(P<0.05)。多因素logistic回归分析发现血清C反应蛋白(C reactive protein,CRP)及S100 A8/A9升高与SMPP密切相关(P<0.05)。受试者操作特征曲线分析结果显示血清S100 A8/A9联合CRP预测SMPP的曲线下面积为0.904,高于S100 A8/A9、CRP单独预测SMPP的AUC(P<0.05),其特异度为0.718,灵敏度为0.952。结论S100 A8/A9与MPP病情严重程度密切相关,S100 A8/A9联合CRP更有利于判断MPP患儿的病情严重程度。

本文通过识别中国城市中微观经营主体的主要功能测算各地区的城市功能分工,继而基于专利数据考察城市功能分工对企业创新的影响和作用机理。研究发现,城市功能分工能够显著促进企业创新,这背后的机制在于,城市功能分工能够促进区域内产业链完整和协同、提高企业供应链稳定性以及拓展企业贸易网络,并且城市功能分工有助于企业知识突破行政边界,在更大地理范围内传播。此外,城市功能分工对企业创新的影响会由于城市间距离、行业属性以及企业业务覆盖度的不同而存在差异。随着市场可达性和中心城市首位度的提高,城市功能分工对企业创新的提升作用趋于增强。本文为中国通过构建优势互补的区域经济布局培育企业创新的新动能提供了参考。

为改善老年人冬季睡眠热舒适性,提高睡眠质量,基于老年人睡眠局部差异热需求研究了分区加热被褥。使用暖体假人及人工气候舱模拟老年人冬季睡眠场景,进行睡眠实验,探究老年人冬季睡眠的加热需求,并比较电加热和热水袋2种加热方式的作用机制,以此为依据提出分区加热被褥设计方案。结果表明:当被褥无加热时,老年人胸部、背部、手部和脚部皮肤温度低于热舒适温度0.5~2.6℃,而背部和脚部更适宜进行局部加热;热水袋加热方式因升温速率高且水温下降后给人体带来接触冷感,而电加热方式升温速率平缓且能维持皮肤温度在34.5~35℃的舒适范围;在背部和脚部组合电加热作用下,被下微环境整体温度得以提升,胸部和手部皮肤温度也升高至热舒适温度范围,即分区电加热方案可有效改善老年人整体及局部睡眠热舒适性。本文研究结果可为开发高性能分区加热被褥提供理论参考及数据支撑。
