Two-dimensional(2D)Ruddlesden-Popper(RP)halide perovskites with diverse structures and properties have drawn increasing attention due to their promising optoelectronic ***,a new all-inorganic Cs_(2)Pb(SCN)_(2)Br_(2) has been reported that opens up new potential for the development of 2D RP ***,recent reports of unusual dual emissions and two-edge absorption in Cs_(2)Pb(SCN)_(2)Br_(2) have generated intense debate about its origin and remains ***,by combining continuous pressure tuning with in situ diagnostics,we have unambiguously revealed the underlying mechanisms that the 2D Cs_(2)Pb(SCN)_(2)Br_(2) exhibits an intrinsic blue emission at 2.66 eV and an absorption edge close to the emission *** the gradually formed CsPbBr_(3) is responsible for the green emission at 2.33 eV with the absorption shoulder at 2.41 ***,by fitting the temperature-dependent intensity of the intrinsic blue emission,we have determined the corrected value of exciton binding energy for 2D Cs_(2)Pb(SCN)_(2)Br_(2) to be 90 ***,an emission enhancement of 2.5 times is achieved in Cs_(2)Pb(SCN)_(2)Br_(2) under a mild pressure within 0.8 GPa,caused by the pressuresuppressed exciton-phonon *** work not only elucidates the origin of the dual emissions and two-edge absorption in Cs_(2)Pb(SCN)_(2)Br_(2),but it also provides a potential means to regulate and optimize the optoelectronic properties of 2D perovskites.

有关ESG的争议始终未曾歇止,ESG本土化更是面临许多挑战,其中主要包括:ESG评级的客观中立性受到质疑、ESG信息披露的规范性仍存不足,以及对漂绿行为的打击和治理仍需强化。当前应直面挑战而不是排斥,并结合我国国情构建具有中国特色的ESG体系,将ESG从外部评价融入内部治理。自ESG兴起以来,其目标共识不仅在理论层面,还在我国法律法规和政策中得到确认,主要体现于:一是中华传统文化思想和法治条件是其基础依据;二是服务国家经济战略,推动产品升级和产业转型是其时代命题;三是推动公司治理的现代化变革是其应有内容;四是促进ESG信息披露与投资决策的良性互动是其重点环节;五是强化对漂绿行为的打击和治理是其责任思维。

目的探讨基于容积超声图像的心脏计算机辅助系统(SonoVCADS)在正常胎儿心脏诊断切面显示中的可行性。方法选取2021年8月至2022年3月在丽水市中心医院超声科行胎儿心脏检查的66名正常单胎胎儿为研究对象,使用SonoVCADS获得容积超声图像314个。由3名不同经验的观察者对每个诊断切面进行评分,计算SonoVCADS显示诊断切面的成功率和一致性,比较3名观察者使用SonoVCADS显示胎儿心脏诊断切面的时间。另随机选取50名胎儿,比较SonoVCADS与二维超声心动图显示胎儿心脏诊断切面的时间。结果3名观察者使用SonoVCADS显示胎儿心脏8个诊断切面的成功率比较,差异均无统计学意义(均P>0.05)。以观察者B(相对经验不足)为例,70.70%的容积超声图像可以成功显示8个诊断切面,13.69%的容积超声图像可以成功显示7个诊断切面,仅4.15%的容积超声图像成功显示的诊断切面数<4个。观察者B的8个诊断切面的Kappa值为0.652~0.854;3名观察者的8个诊断切面的Kappa值为0.536~0.752。观察者C(检查经验丰富)花费的时间明显少于观察者A和观察者B(均P<0.05)。观察者C使用SonoVCADS显示胎儿心脏8个诊断切面的时间明显短于二维超声心动图(P=0.018)。结论SonoVCADS显示胎儿心脏8个诊断切面的成功率较高,对操作人员的依赖性低,且具有良好的一致性和检查效率。

Residual feed intake(RFI)is a metric that provides a more accurate measure of feed *** lower the RFI,the higher the feed *** changes in the host microbiome and metabolome contribute to the greater feed efficiency of low RFI(LRFI)*** aim of this study was to explore the differences in rumen microorganisms,rumen metabolites and plasma metabolites of Hu sheep with differing RFI through the microbiome and metabolome.A total of 80 Hu sheep were *** experiment consisted of a 15-d pretrial period and a 128-d experimental *** RFI in the experimental period was calculated for all sheep,and the sheep were screened into high RFI(HRFI,n=8)and LRFI(n=8)*** HRFI and LRFI sheep did not differ in their initial and final body weights,average daily gain and body measurements,but the dry matter intake of LRFI sheep was significantly decreased(28.4%,P<0.001).The sheep with LRFI had higher digestibility of crude protein(P=0.010)and ether extract(P=0.010)compared to HRFI *** concentrations of acetate(P=0.036),propionate(P=0.010),valerate(P=0.027)and total volatile fatty acids(P=0.048)in rumen of LRFI group were higher compared to HRFI *** results of 16S rDNA sequencing indicated that the sheep with LRFI had higher proportions of Prevotella genus in rumen liquid(P=0.031).The rumen metabolome and plasma metabolome results showed that the citrate cycle,pyruvate metabolism and alanine,aspartate and glutamate metabolism processes were more active for sheep in LRFI group,which provided more energy substrate such as malic acid,oxoglutaric acid and citric *** conclusion,sheep with LRFI can utilize feed more efficiently,and the more active energy metabolism pathway and the production of energy substances may account for the higher feed efficiency.

作为最严厉的法律责任形式,刑事责任的适用要求严格区分罪与非罪、此罪与彼罪、轻重与重罪。以此考察互联网金融刑事治理"风暴",发现其面临如下困境:人们虽然意识到互联网金融蕴含犯罪风险,但在其异化过程中由于没有清晰的底线标准,即使是法律专业人士也未能对其刑事法律风险防范提供可操作的指引;互联网金融的刑事治理表现为"事后诸葛亮式"的滞后反应;当"普遍违法"状态下"唯后果"进行"选择性执法"时,刑事治理的权威性受到质疑;在严厉惩治的背景下,司法实践中的经验判断是否突破了罪刑法定值得探讨。对于互联网金融的监管,强调要明确适度监管的必要性;构建中央与地方的分级监管体系,赋予地方对互联网金融预防风险与及时处置的权限;在"穿透式"监管需求下,提高互联网金融科技监管能力。
