目的应用美国临床和实验室标准化协会(CLSI)EP9-A3文件评价两种方法学检测血清总胆红素结果的可比性,评估常规检测系统能否满足临床需求。方法收集北京航天总医院患者新鲜血清标本40例,以总胆红素Doumas参考方法作为参比系统,迈克氧化法试剂及雅培C16000生化分析仪组成的检测系统作为待评系统,对检测结果进行分析,选取最适合的回归模型拟合回归方程,计算其在医学决定水平处的偏移,以国家卫健委临床检验中心室间质评1/2允许总误差TEa(7.5%)为可接受标准。结果待评系统与参比系统的检测结果分别为56.27(32.90,125.33)μmol/L、63.05(36.09,139.16)μmol/L,差异有统计学意义(Z=-5.511,P<0.05)。选择Deming和Passing-Baklok回归对结果进行线性拟合,回归方程分别为Y=0.958 X-2.756(r=0.998)和Y=0.942 X-1.453(r=0.999)。将医学决定水平值34.2、171、342分别代入回归方程,计算得到的相对偏移分别为-13.06%、-5.99%、-5.13%和-10.58%、-6.88%、-6.42%。结论待评的常规检测系统与参比系统间存在明显负偏移,低值医学决定水平处的偏移不可接受。

Federated learning(FL)， as a distributed learning paradigm， allows multiple medical institutions to collaborate on learning without the need to centralize all client data. However， existing methods pay little attention to more challenging medical image semantic segmentation tasks， especially in the scenario of the imbalanced dataset in federated few-shot learning. In this paper， we propose a subnetwork-based federated few-shot organ image segmentation method. Firstly， individual clients train using local training samples and then upload local model gradients to the server. The server utilizes their respective local model gradients to update the subnetwork maintained on the server and generate aggregation weights for forming personalized model parameters. Through this method， we can learn the similarities between different clients to address data heterogeneity issues. In addition， to enhance the communication efficiency between clients and the server， we have also designed a personalized layer aggregation strategy， which only transmits partial layer model parameters during the communication process to improve communication efficiency. Finally， we conducted experiments on ABD-MRI and ABD-CT datasets to demonstrate the effectiveness of our method.

为提高热带潮湿气候条件下蒸发冷却空调系统的制冷效率和舒适度,提出一种复合式蒸发预冷空调系统。该复合系统将间接蒸发式换热器作为预冷装置与传统的机械蒸汽压缩机组相结合,通过建立针对间接蒸发换热器和冷却盘管的数学模型,研究利用室内排风作为工作空气的预冷性能。数值模拟结果表明,在潮湿环境下,间接蒸发冷却预冷装置可以降低空气温度并可将空气中的水分冷凝。在典型工况下,复合系统能够采用更高温度的冷冻水。因预冷过程以及冷水机组效率的提高,该复合式蒸发预冷空调系统能够在热带潮湿环境下实现节能。

L10-FePt-type bit-patterned media has provided a promising alternative for ultrahigh-density magnetic recording systems in the current digital era, but rapid fabrication of magnetic patterns with hyperfine bit islands is still challenging, especially with the target for miniaturization and scalable production simultaneously. Herein, Fe,Pt-containing block copolymers were utilized as single-source precursors for solution-processable patterning and subsequent generation of the demanding magnetic FePt dots by in situ pyrolysis. High-throughput nanoimprint lithography was initially employed to fabricate the predefined bit cells precisely,and then the intrinsic self-assembly of phase-separated block copolymers further drove the formation of accurate bit *** from the synergistic effect of top-down lithographic approach and bottom-up self-assembly, the customizable patterns could be achieved for large-scale mass production in targeted areas, but high-density isolated dots could also be accurately aligned along the patterned features after subsequent self-assembly. This reliable strategy would provide a good avenue to precisely construct ultrahigh-density magnetic data storage devices.

Solution-processed Cu（In,Ga）Se2（CIGS） solar cells suffer from serious carrier recombination and power conversion efficiency（PCE） loss because of the poor film properties and easy formation of ***, we propose Ag&Se co-selenization strategy to enhance the crystallization and passivate harmful defects of the CIGS films. The formation of Ag-Se phase during the selenization process enables the formation of large grains and suppresses the deep level defects. It is found that Ag doping can enlarge the depletion region width, lower the Urbach energy and prolong the carrier lifetime. As a result, a champion solution-processed CIGS solar cell presents a high efficiency of 16.48% with the highly improved opencircuit voltage（VOC） of 662 m V and fill factor（FF） of 75.8%. This work provides an efficient strategy to prepare high quality solution-processed CIGS films for high-performance CIGS solar cells.

政治叙事是儒家树立理想人格、阐释社会正义、教化广大民众的常见载体与主要途径,可谓是展现儒家伦理的基本场所。宋代诗话政治叙事看似散乱无章,实则是这种主流观念的诗学再现,并汇集为人格伦理、正义伦理、诗教伦理三重主体话语,展示出宋人对儒家伦理的时代阐释。与官方主流话语相比,宋代诗话政治叙事并未脱离史实,反而更具传播力。这不仅印证了诗话是按传播逻辑成篇的文体特性,而且有助于拓展智识精英圈的政治认知,深化受众的伦理意识,并为宋代意识形态建设提供了典型样本及话语助力。

五四运动爆发后,日本主流舆论将其定性为“排日运动”,多指责中国青年学生排斥日本,认为英美势力与中国亲英美派政客煽动青年学生促成了“暴动”。部分日本在华媒体人和以吉野作造为代表的日本新知识分子以及大阪报刊《大正日日新闻》却肯定了五四运动体现出的进步思想,呼吁日本民众理性看待中国的民众运动。其中,《大正日日新闻》1920年新年号连载“中国名士之对日意见”,这些意见集中介绍了五四运动、新思想运动的真义,体现了五四运动后日本知识界对中国新思想的关注,同时也呈现出日本对华观的多面性与复杂性。
