    由于化石燃料对环境的不利影响,绿色能源技术正逐渐成为亟待解决的热点问题之一。理论家和实验家正在研究和开发的策略之一是使用光电化学(PEC)电池,它们正在成为从水分解产生氢的候选者。然而,创建满足PEC水分解要求的光电极已成为将该技术实现商业成果的主要障碍。这里,我们构造了一个异质结构,它由MoS2/TiO2/Au纳米颗粒(NPs)组成,以克服光电阳极的缺点。由于对电荷转移的依赖,MoS2/TiO2的带隙和利用AuNP作为激发剂,通过局域表面等离子体共振效应以及增加热电子注入阴极,导致光催化活性得到改善。结果表明,光电流密度从TiO2的2.3μAcm-2显着增加到MoS2/TiO2/AuNP的约16.3μAcm-2。这项工作揭示了一条有希望的途径,通过将二维材料与金属NP结合来增强PEC电池光电电极中的可见光吸附和电荷转移。
    Green energy technology is generally becoming one of hot issues that need to be solved due to the adverse effects on the environment of fossil fuels. One of the strategies being studied and developed by theorists and experimentalists is the use of photoelectrochemical (PEC) cells, which are emerging as a candidate to produce hydrogen from water splitting. However, creating photoelectrodes that meet the requirements for PEC water splitting has emerged as the primary obstacle in bringing this technology to commercial fruition. Here, we construct a heterostructure, which consists of MoS2/TiO2/Au nanoparticles (NPs) to overcome the drawbacks of the photoanode. Owing to the dependence on charge transfer, the bandgap of MoS2/TiO2and the utilization the Au NPs as a stimulant for charges separation of TiO2by localized surface plasmon resonances effect as well as the increase of hot electron injection to cathode, leading to photocatalytic activities are improved. The results have recorded a significant increase in the photocurrent density from 2.3μAcm-2of TiO2to approximately 16.3μAcm-2of MoS2/TiO2/Au NPs. This work unveils a promising route to enhance the visible light adsorption and charge transfer in photo-electrode of the PEC cells by combining two-dimensional materials with metal NPs.

    背景:命名实体识别(NER)是自然语言处理中的一项基本任务。然而,它之前通常是命名实体注释,这带来了一些挑战,尤其是在临床领域。例如,确定实体边界是注释者之间最常见的分歧来源之一,因为诸如是否应该注释修饰语或外围词。如果未解决,这些会导致产生的语料库不一致,然而,另一方面,严格的指导方针或裁决会议可以进一步延长已经缓慢和复杂的过程。
    目的:本研究的目的是通过评估两种新颖的注释方法来解决这些挑战,宽松的跨度和点注释,旨在减轻精确确定实体边界的难度。
    方法:我们通过对日本医学病例报告数据集的注释案例研究来评估其效果。我们比较注释时间,注释者协议,和生成的标签的质量,并评估对在注释的语料库上训练的NER系统的性能的影响。
    结果:我们看到了标签过程效率的显着提高,与传统的边界严格方法相比,整体注释时间减少了25%,注释者协议甚至提高了10%。然而,与传统的注释方法相比,即使是最好的NER模型也表现出一些性能下降。
    结论:我们的发现证明了注释速度和模型性能之间的平衡。尽管忽略边界信息会在一定程度上影响模型性能,这是由显著减少注释者的工作量和显著提高注释过程的速度所抵消的。这些好处可能在各种应用中被证明是有价值的,为开发人员和研究人员提供了一个有吸引力的折衷方案。
    BACKGROUND: Named entity recognition (NER) is a fundamental task in natural language processing. However, it is typically preceded by named entity annotation, which poses several challenges, especially in the clinical domain. For instance, determining entity boundaries is one of the most common sources of disagreements between annotators due to questions such as whether modifiers or peripheral words should be annotated. If unresolved, these can induce inconsistency in the produced corpora, yet, on the other hand, strict guidelines or adjudication sessions can further prolong an already slow and convoluted process.
    OBJECTIVE: The aim of this study is to address these challenges by evaluating 2 novel annotation methodologies, lenient span and point annotation, aiming to mitigate the difficulty of precisely determining entity boundaries.
    METHODS: We evaluate their effects through an annotation case study on a Japanese medical case report data set. We compare annotation time, annotator agreement, and the quality of the produced labeling and assess the impact on the performance of an NER system trained on the annotated corpus.
    RESULTS: We saw significant improvements in the labeling process efficiency, with up to a 25% reduction in overall annotation time and even a 10% improvement in annotator agreement compared to the traditional boundary-strict approach. However, even the best-achieved NER model presented some drop in performance compared to the traditional annotation methodology.
    CONCLUSIONS: Our findings demonstrate a balance between annotation speed and model performance. Although disregarding boundary information affects model performance to some extent, this is counterbalanced by significant reductions in the annotator\'s workload and notable improvements in the speed of the annotation process. These benefits may prove valuable in various applications, offering an attractive compromise for developers and researchers.

    生物材料领域的快速发展,计算机辅助设计,和制造业已经推动了清晰的矫正器疗法(CAT)成为一种全面的正畸治疗方式。在设定最终治疗目标时,使用清晰的矫正器实现计划的牙齿移动的效率是一个重要的考虑因素,以及根据现有证据计算治疗时间和费用。当代研究结果证实,CAT最常见的临床问题之一是数字治疗计划中的规定结果与给定系列对准器的临床结果之间的差异。对牙齿运动的不准确预测可能不仅会导致矫正器治疗的持续时间延长,而且还需要完善策略;但它也可能会引起其他问题,如患者倦怠和复发的可能性增加。本文的作者阐明了一些关键要素,这些要素可能有助于解决数字处方和临床结果之间的这种差异,基于基于证据的方法,关于CAT的可预测性和准确性。强大的诊断能力,明智的案例选择,对各种正畸牙齿运动的坚实的生物力学理解,一个与技术和材料发展保持同步的研究框架,并提供关于CAT局限性的循证知识;最重要的是,临床医生根据不同的临床情况不断创新的能力,所有这些都有助于实现治疗的可预测性,功效,和效率与CAT。
    Expeditious strides in the fields of biomaterials, computer-aided design, and manufacturing have catapulted clear aligner therapy (CAT) to become a comprehensive orthodontic treatment modality. The efficiency of achieving planned tooth movement with clear aligners is a significant consideration while setting up the final treatment goals, as well as calculating treatment times and costs based on the available evidence. Contemporary research outcomes confirm that one of the most commonly reported clinical concerns with CAT is the discrepancy between the prescribed outcome in the digital treatment plan and the clinically achieved outcome from a given series of aligners. Inaccurate prediction of tooth movements may not only lead to a prolonged duration of aligner treatment with an additional need for refinement strategies; but it may also cause other concerns, such as patient burnout and increased potential for relapse. The authors of this paper have elucidated some of the critical elements that may help address this discrepancy between digitally prescribed and clinical outcomes based on an evidence-based approach with regard to the predictability and accuracy of CAT. A strong diagnostic acumen, judicious case selection, solid biomechanical understanding of various types of orthodontic tooth movements, a research framework that keeps pace with technological and material developments and provides evidence-based knowledge of the limitations of CAT; and above all, the ability of the clinician to continually innovate as per different clinical scenarios, all contribute to attaining treatment predictability, efficacy, and efficiency with CAT.

    全要素生产率是经济高质量发展的重要标志。目前,数字经济能否为提高全要素生产率注入新的动力,这一问题在中国已经成为一个突出的问题。本文利用2011-2020年中国省际面板数据,构建了一种新的非期望产出,用基于松弛测度(SBM)的非期望全要素生产率(CTFP)。然后,本文利用固定效应(FE)面板模型和中介效应模型探讨了数字经济(DIG)对CTFP的影响。结果表明,CTFP平均增长3.9%,技术效率贡献-1.1%,技术进步贡献率为5.0%。技术进步是CTFP增长的主要源泉。实证结果表明,DIG对CTFP有积极而显著的影响。本文进行了各种稳健性测试,结果与之前的结论保持一致。此外,机制测试表明,DIG对CTFP的促进作用可归因于三个主要效应:技术创新,要素禀赋结构和教育水平。此外,异质性分析结果表明,DIG对CTFP的促进作用在中国东部地区存在,中部和西部地区。这项研究的结果可以作为一个有价值的参考,为有关中国环境治理和经济高质量发展的决策过程提供参考。
    Total factor productivity is an important symbol of high-quality economic development. At present, the question of whether the digital economy can infuse fresh impetus into enhancing total factor productivity has emerged as a prominent concern in China. This paper constructs a new undesirable output to measure comprehensive total factor productivity (CTFP) with the slack-based measure (SBM) undesirable Malmquist-Luenberger index by using 2011-2020 Chinese provincial panel data. Then, this paper explores the impact of the digital economy (DIG) on CTFP with a fixed effects (FE) panel model and a mediating effect model. The results show that CTFP increases by an average of 3.9%, technical efficiency contributes -1.1%, and the contribution rate of technological progress is 5.0%. Technological progress is the main source of CTFP growth. The empirical findings show that the DIG has a positive and significant impact on CTFP. This paper conducts various robustness tests, and the results remain consistent with the previous conclusion. Moreover, mechanism tests suggest that the promoting effect of the DIG on CTFP can be attributed to three main effects: technological innovation, the factor endowment structure and the educational level. Furthermore, the results of heterogeneity analysis demonstrate that the promoting effect of the DIG on CTFP exists in China\'s eastern, central and western regions. The findings of this research can serve as a valuable reference for informing decision-making processes related to environmental governance and high-quality economic development in China.

    猪胃肠道中的微生物种群可以通过将纤维状副产物掺入日粮中而受到影响。这项研究调查了在猪饮食中加入两种类型的干橄榄饼(OC)对粪便细菌组成的影响。粪便菌群与生长性能的相关性,营养素消化率,还评估了肠道发酵模式和浆液气体排放。将30头雄性Pietrainx(长白猪x大白猪)(47.9±4.21kg)分为三组:对照组(C),一组饲喂20%部分脱脂OC(20PDOC)的饮食,一组饲喂20%旋风OC(20COC)的饮食21天。分析在提供实验饮食之前和之后收集的粪便样品的16SrRNA基因的V3-V4区域。猪称重,在整个研究过程中记录饲料摄入量。测量来自浆料的潜在氨和甲烷排放。α多样性指数没有发现显著差异。分类学分析显示,Firmicutes和Bacteroidota在所有组的门水平上占主导地位。使用ALDEx的差异丰度分析显示,对于门的各种细菌,属,和实验结束时的物种水平。来自20PDOC和20COC组的猪表现出增加的健康促进细菌的丰度,例如门水平的Plattomycetota和属水平的Allisonella和来自Eggerthellaceae科的一个未鉴定的属。这些变化影响了浆料中短链脂肪酸(SCFA)的浓度,导致更大的乙酸,丁酸,OC喂养组中的己酸和庚酸,尤其是20COC猪。波动率分析显示,未培养的拟杆菌和未培养的Selenomonadaceae与能量消化率之间存在显着正相关(p<0.05)。单球形和脱硫弧菌与总SCFA呈显著正相关(p<0.05),表明对肠道发酵的影响很大。然而,生长性能参数和潜在的气体排放与特定细菌属没有显着相关性。总之,我们的结果表明,在猪日粮中加入OC可以积极调节和促进肠道微生物群的有利组成和功能。此外,养分消化率和肠道发酵模式可能与特定的微生物种群有关。
    The microbial population in the pig\'s gastrointestinal tract can be influenced by incorporating fibrous by-products into the diets. This study investigated the impact of including two types of dried olive cake (OC) in pigs\' diets on fecal bacterial composition. The correlation between fecal microbiota and growth performance, nutrient digestibility, gut fermentation pattern and slurry gas emissions was also evaluated. Thirty male Pietrain x (Landrace x Large white) pigs (47.9 ± 4.21 kg) were assigned to three groups: a control group (C), a group fed a diet with 20% partially defatted OC (20PDOC), and a group fed a diet with 20% cyclone OC (20COC) for 21 days. Fecal samples collected before and after providing the experimental diets were analyzed for the V3-V4 region of the 16S rRNA gene. Pigs were weighed, and feed intake was recorded throughout the study. Potential ammonia and methane emissions from slurry were measured. No significant differences in alpha diversity indexes were found. The taxonomic analysis revealed that Firmicutes and Bacteroidota phyla were dominant at the phylum level across all groups. Differential abundance analysis using ALDEx showed significant differences among groups for various bacteria at the phylum, genus, and species levels at the end of the experiment. Pigs from 20PDOC and 20COC groups exhibited increased abundances of health-promoting bacteria, such as Plactomycetota at the phylum level and Allisonella and an unidentified genus from the Eggerthellaceae family at the genus level. These changes influenced short-chain fatty acids\' (SCFA) concentration in slurries, leading to greater acetic, butyric, caproic and heptanoic acids in OC-fed groups, especially 20COC pigs. A volatility analysis revealed significant positive correlations (p < 0.05) between Uncultured_Bacteroidales and Unculured_Selenomonadaceae and energy digestibility. Monoglobus and Desulfovibrio showed a positive significant (p < 0.05) correlation with total SCFA, indicating a high impact on gut fermentation. However, growth performance parameters and potential gas emission displayed no significant correlations with a specific bacterial genus. In conclusion, our results suggest that OC inclusion into pig diets could positively modulate and contribute to the gut microbiota\'s favorable composition and functionality. Also, nutrient digestibility and gut fermentation patterns can be associated with specific microbial populations.

    背景:连续肾脏替代疗法(CKRT)可用于医院中一些最危重的患者。这种疗法是昂贵的并且需要多学科团队的协调以确保规定的剂量被递送。随着对重症监护护理人员的需求增加,重症监护病房患者的复杂性增加,我们评估了专门的肾脏技术专家在确保提供处方剂量方面的作用.因此,本研究的目的是调查在阿拉伯联合酋长国,支持重症监护病房护士与专业肾脏科医师合作对优化CKRT课程效率的影响.
    方法:这是一项回顾性研究,比较了在专业肾脏技术专家监督下接受CKRT的危重病人与2021年未承保的危重病人。
    结果:共纳入了158名患者的331个疗程。与未覆盖组相比,专业肾脏技术人员覆盖的患者的平均过滤器寿命更长(66vs.59小时,p=0.019)。在通过多元回归分析对风险因素进行调整后(即,年龄,性别,机械通气,脓毒症,平均动脉压,血管升压药,和SOFA)可能会影响CKRT机器的过滤器寿命,专门的肾脏技术专家的存在导致过滤器寿命显著延长(系数0.129;CI95%1.080,11.970;p值:0.019).
    结论:我们的研究表明,专业的肾脏技术人员在延长CKRT机的过滤器寿命和优化CKRT机的效率方面发挥着至关重要的作用。进一步的研究应该集中在其他潜在的好处,有专门的肾脏技术人员进行CKRT会议,并确认这项研究的发现。此外,可以进行成本效益分析,以确定由专业团队执行CKRT的经济影响.
    BACKGROUND: Continuous renal replacement therapy (CKRT) is delivered to some of the most critically ill patients in hospitals. This therapy is expensive and requires coordination of multidisciplinary teams to ensure the prescribed dose is delivered. With increased demands on the critical care nursing staff and increased complexities of patients admitted to critical care units, we evaluated the role of specialized renal technologists in ensuring the prescribed dose is delivered. Therefore, the aim of this study is to investigate the impact of supporting intensive care unit nurses with specialized renal technologists on optimizing efficiency of CKRT sessions in the United Arab Emirates.
    METHODS: This is a retrospective study that compared critically ill patients on CKRT overseen by specialized renal technologists versus who are non-covered in the year 2021.
    RESULTS: A total of 331 sessions on 158 patients were included in the study. The mean filter life was longer in specialized renal technologists-covered patients compared to the non-covered group (66 vs. 59 h, p = 0.019). After adjustment by multiple regression analysis for risk factors (i.e., age, gender, mechanical ventilation, sepsis, mean arterial pressure, vasopressors, and SOFA) that may affect CKRT machines\' filter life, presence of a specialized renal technologists resulted in significantly longer filter life (co-efficient 0.129; CI 95% 1.080, 11.970; p-value: 0.019).
    CONCLUSIONS: Our study suggests that specialized renal technologists play a vital role in prolonging CKRT machine\'s filter life span and optimizing CKRT machine\'s efficiency. Further research should focus on other potential benefits of having specialized renal technologists performing CKRT sessions, and to confirm the finding of this study. Additionally, a cost-benefit analysis could be conducted to determine the economic impact of having specialized teams performing CKRT.
