    对植物生长有显著的调节作用,但是功能性状对中华毛竹寄生的响应机制以及性状与高光谱特征之间的权衡关系尚不清楚。我们研究了大叶黄鱼的功能性状响应和高光谱特征,中国最常见的城市绿篱植物,中国的寄生虫。结果表明,毛竹寄生导致叶片功能性状的差异:叶片厚度,气孔密度,叶片干物质含量显著增加,而叶面积,叶片重量,比叶面积,叶绿素含量指数,叶片组织密度显著降低。值得注意的是,C.chinensis的寄生改变了气孔的空间分布格局,促进了气孔的均匀分布。此外,用C.chinensis寄生处理的叶片的光谱反射率趋于增加。C.chinensis的寄生现象导致了叶片高光谱反射率的“蓝移”。光谱参数与叶片功能性状之间存在显著的相关性,叶片生物量占水分胁迫带反射率变化的83%。总的来说,C.chinensis的寄生性决定了植物资源利用的战略方式,并通过影响性状的差异来影响植物策略的变化。城市植物更倾向于将资源投资于养分储存能力,而牺牲了资源投资于光合能力和防御机制。植物生态战略由资源获取向资源保护转变。这一发现提出了一种新的策略,即城市树种可以在寄生植物的干扰下改变功能性状的可塑性,以实现生存和生长。
    Cuscuta chinensis have a significant regulatory effect on plant growth, but the response mechanism of functional traits to the parasitism of C. chinensis and the trade-off relationship between traits and hyperspectral characteristics are not clear. We investigated the functional trait response and hyperspectral characteristics of Euonymus japonicus, the most common urban hedge plant in China, to the parasitism of C. chinensis. The results showed that the parasitism of C. chinensis led to the difference of leaf functional traits: the leaf thickness, stomatal density, and leaf dry matter content were significantly increased, whereas the leaf area, leaf weight, specific leaf area, chlorophyll content index, and leaf tissue density were significantly decreased. Notably, the parasitism of C. chinensis changed the spatial distribution pattern of stomata and promoted the stomata to be evenly distributed. Furthermore, the spectral reflectance of leaves treated with the parasitism of C. chinensis tended to increase. The parasitism of C. chinensis led to the \"blue shift\" of hyperspectral reflectance of leaves. There was a significant correlation between spectral parameters and leaf functional traits, and leaf biomass accounted for 83% of the variation in reflectance of the water stress band. In general, the parasitism of C. chinensis determines the strategic way of plant utilization of resources and affects the change of plant strategy by affecting the difference of traits. Urban plants were more inclined to invest resources in nutrient storage capacity at the expense of resources investment in photosynthetic capacity and defense mechanism. The plant ecological strategy changed from resource acquisition to resource conservation. This finding comes up with a new strategy that urban tree species can modify the plasticity of functional traits for survival and growth under the interference of parasitic plants.

    人乳磷脂(HMPL)在婴儿的神经发育和生长中起着不可或缺的作用。在这项研究中,从人乳和其他天然磷脂来源(包括5种动物来源和2种植物来源)共检测到37种磷脂脂肪酸(PLFA)和139种磷脂分子.此外,建立了HMPL的相似性评价模型,包括磷脂类,PLFA,和磷脂分子种类,评估它们的天然替代品。HMPL替代品在这三个维度中最接近的分数是0.89、0.72和0.77,属于马奶,山羊奶,还有骆驼奶,分别。骆驼奶的综合相似度得分最高,为0.75,而大豆磷脂得分最低(0.22)。因此,这些结果不仅监测了HMPL及其替代品的立体化学结构,也进一步为婴儿配方食品的发展提供了新的见解。
    Human milk phospholipids (HMPLs) play an indispensable role in the neurodevelopment and growth of infants. In this study, a total of 37 phospholipid fatty acid (PLFA) species and 139 phospholipid molecular species were detected from human milk and other natural phospholipid sources (including 5 animal-derived species and 2 plant species). Moreover, a similarity evaluation model for HMPLs was established, including phospholipid classes, PLFAs, and phospholipid molecular species, to evaluate their natural substitutes. The closest scores for HMPL substitute in these three dimensions was 0.89, 0.72, and 0.77, which belonged to mare milk, goat milk, and camel milk, respectively. The highest comprehensive similarity score was obtained by camel milk at 0.75, while the lowest score was observed in soybean phospholipid (0.22). Therefore, these results not only monitored the stereochemical structure of HMPLs and their substitutes, but also further provided new insights for the development of infant formulae.

    With the tourism industry continuing to boom, the importance of tourism mascots in promoting and publicizing tourism destinations is becoming increasingly prominent. Three core dimensions, market trend, appearance design, and audience feedback, are numerically investigated for deeply iterating tourism mascot design. Further, a subjective and objective evaluation weighting model based on the hierarchical analysis method (AHP) and entropy weighting method is proposed, aiming to utilize the advantages of these methods and ensure the entireness and correctness of results. Taking the mascots of six famous tourist attractions in Xi\'an as an example, the feasibility and effectiveness of the evaluation model are verified. Data analysis and modeling results confirm that the three core evaluation indexes of scalability, innovation, and recommendation should be focused on in the design of tourism mascots in the three dimensions of market trends, appearance design, and audience feedback. The evaluation index scores are 0.1235, 0.1170, and 0.1123, respectively, which further illustrates the priority of mascot design. The evaluation model constructed by the research provides decision-makers with a comprehensive evaluation tool from the perspective of tourist experience, and also effectively assists the optimization process of mascot design. In addition, the model has good versatility and adaptability in structural design and evaluation logic and can be widely used in the optimization and evaluation research of brand mascots.

    中风患者的预后受到营养不良的极大威胁。然而,没有模型来预测住院卒中患者营养不良的风险。这项研究开发了一种预测模型,用于识别中风患者的高危营养不良。
    选择两家三级医院的脑卒中患者作为研究对象。采用二元logistic回归建立模型。使用各种指标评估模型的性能,包括接收器工作特性曲线,Hosmer-Lemeshow测试,灵敏度,特异性,尤登指数,临床决策曲线,和风险分层。
    总共319名中风患者被纳入研究。其中,27%的人在医院中营养不良。预测模型包括所有独立变量,包括吞咽困难,肺炎,肠内营养,BarthelIndex,上臂周长,和小腿围(均p<0.05)。建模组的AUC面积为0.885,验证组,是0.797。当风险阈值概率在0%到80%之间时,预测模型产生更大的净临床效益,如临床决策曲线所示。Hosmer检验的所有p值均>0.05。该模型的最佳截断值为0.269,灵敏度为0.849,特异性为0.804。风险分层后,在建模组和验证组,MRS评分和营养不良发生率均随着风险水平的升高而显著增加(p<0.05).
    这项研究开发了一种中风患者营养不良的预测模型。实践证明,该模型具有良好的微分和标定性。
    UNASSIGNED: The prognosis of stroke patients is greatly threatened by malnutrition. However, there is no model to predict the risk of malnutrition in hospitalized stroke patients. This study developed a predictive model for identifying high-risk malnutrition in stroke patients.
    UNASSIGNED: Stroke patients from two tertiary hospitals were selected as the objects. Binary logistic regression was used to build the model. The model\'s performance was evaluated using various metrics including the receiver operating characteristic curve, Hosmer-Lemeshow test, sensitivity, specificity, Youden index, clinical decision curve, and risk stratification.
    UNASSIGNED: A total of 319 stroke patients were included in the study. Among them, 27% experienced malnutrition while in the hospital. The prediction model included all independent variables, including dysphagia, pneumonia, enteral nutrition, Barthel Index, upper arm circumference, and calf circumference (all p < 0.05). The AUC area in the modeling group was 0.885, while in the verification group, it was 0.797. The prediction model produces greater net clinical benefit when the risk threshold probability is between 0% and 80%, as revealed by the clinical decision curve. All p values of the Hosmer test were > 0.05. The optimal cutoff value for the model was 0.269, with a sensitivity of 0.849 and a specificity of 0.804. After risk stratification, the MRS scores and malnutrition incidences increased significantly with escalating risk levels (p < 0.05) in both modeling and validation groups.
    UNASSIGNED: This study developed a prediction model for malnutrition in stroke patients. It has been proven that the model has good differentiation and calibration.

    本文讨论了专有决策模型的概念,该模型可以确定是否可以以安全的方式在不受防洪堤保护且有洪水风险的地区进行计划开发。该模型用于评估在洪水风险地区塑造发展的可能性,例如Olender村庄的一种类型-位于Warta河(波兰西部)洪泛区的分散村庄。到目前为止,没有综合评价方法支持洪水风险区的适当空间规划。使用多准则分析方法能够指定本次评估的关键标准,构成决策支持系统的基础。此外,详细的方法可以确定所研究的地区是否可以保留其当前的功能性质,以及是否有基于Olpder村特征的进一步空间发展的潜力。提出的方法可以很容易地适应位于不同发展水平国家的其他文化领域,传统,景观或气候。
    The paper discusses the concept of a proprietary decision-making model that allows for determining whether the planned development in areas not protected by flood embankments and at risk of flooding can be shaped in a safe manner. The model was used to evaluate the possibility of shaping the development in flood-risk areas on the example of one of the types of Olęder villages - a dispersed village located in the floodplains of the Warta River (western Poland). So far, there has been no comprehensive evaluation method supporting proper spatial planning for flood-risk areas. The use of multi-criteria analysis methods enabled to specify the key criteria of this evaluation, which form the basis of the decision-making support system. Additionally, the elaborated method enables to determine whether the localities under study can retain their current functional nature and if there is a potential for further spatial development based on the characteristics of an Olęder village. The presented methodology can be easily adapted to other cultural areas located in countries with different levels of development, traditions, landscape or climate.

    银屑病是一种常见的炎症性皮肤病,严重影响患者的生活质量。银屑病的诊断主要依据临床和病理特征,评估取决于银屑病面积和严重程度指数(PASI)。然而,很少有可靠和准确的评估方法来评估病变的严重程度和治疗效果。这项工作从GEO数据集中鉴定了17个模型基因,并通过LASSO回归建立了6个银屑病评估模型,线性回归,和随机森林分开。在不同的GEO数据集中对模型进行了训练和评估。所有6个模型在训练和测试数据中准确地分类了银屑病皮损和非皮损,并显示良好的AUC。在生物制品处理的样品中,模型评分与病变严重程度呈正相关,与治疗时间呈负相关。因此,模型具有评估治疗效果的潜力。此外,在角质形成细胞中检测模型基因的表达,IMQ诱导的银屑病小鼠的皮肤,和牛皮癣患者的病变。在细胞因子刺激的角质形成细胞和银屑病病变中,模型基因的RNA和蛋白质水平如预期的那样增加。这项工作提供了评估银屑病皮损严重程度和生物制剂治疗效果的新方法。
    Psoriasis is a common inflammatory skin disease that seriously affects the patient\'s quality of life. The diagnosis of psoriasis is mainly based on clinical and pathological features, and the assessment depends on the psoriasis area and severity index (PASI). However, there are few reliable and accurate evaluation methods to assess lesion severity and therapeutic effects. This work identified 17 model genes from GEO datasets and established 6 psoriasis evaluation models by LASSO regression, linear regression, and random forest separately. Models were trained and evaluated in different GEO datasets. All 6 models accurately classified psoriatic lesions and non-lesional skin in training and testing data, and showed good AUC. In biologics-treated samples, the model scores were positively correlated with the severity of lesions and negatively correlated with treatment length. Thus, models have the potential to assess the therapeutic effects. In addition, the expression of model genes was examined in keratinocytes, skin of IMQ-induced psoriatic mice, and lesions of psoriasis patients. The RNA and protein levels of model genes increased in cytokine-stimulated keratinocytes and psoriatic lesions as expected. This work provides new methods to assess the lesion severity and therapeutic effects of biologics in psoriasis.

    制备了Ni-Mn@KL臭氧催化剂,用于反渗透膜浓缩液的高效处理。系统研究了Ni-Mn@KL臭氧催化氧化的工作条件和反应机理。然后,建立了一个全面的CRITIC加权耦合协调度评价模型。通过扫描电子显微镜对Ni-Mn@KL进行了表征,BET,X射线衍射,X射线光电子能谱,能量色散光谱法,和X射线荧光光谱法,发现条纹颗粒具有较大的比表面积和均匀的表面分散。在初始pH值为7.9(原水)的最佳工作条件下,反应高径比为10:1,臭氧曝气强度为0.3L/min,催化剂填充率为10%,最大COD去除率为60.5%。自由基猝灭实验表明,OH氧化在Ni-Mn@KL催化的臭氧氧化体系中起主导作用,反应体系符合二级反应动力学规律。Ni-Mn@KL催化剂经反复使用后,具有良好的催化性能和力学性能。实践要点:Ni-Mn@KL催化剂可以实现对RO膜浓缩液的有效处理。以低成本获得了高COD去除率的RO膜浓缩液。Ni-Mn@KL催化剂促进臭氧分解生成·OH和O2-·氧化有机物。Ni-Mn@KL催化剂在反复使用后可以保持良好的稳定性。建立了临界重量耦合配位模型来评估催化臭氧化。
    Ni-Mn@KL ozone catalyst was prepared for the efficient treatment of reverse osmosis membrane concentrates. The working conditions and reaction mechanism of the ozone-catalyzed oxidation by Ni-Mn@KL were systematically studied. Then, a comprehensive CRITIC weighting-coupling coordination evaluation model was established. Ni-Mn@KL was characterized by scanning electron microscopy, BET, X-ray diffraction, X-ray photoelectron spectroscopy, energy-dispersive spectrometry, and X-ray fluorescence spectrometry and found to have large specific surface area and homogeneous surface dispersion of striped particles. Under the optimum working conditions with an initial pH of 7.9 (raw water), a reaction height-to-diameter ratio of 10:1, an ozone-aeration intensity of 0.3 L/min, and a catalyst filling rate of 10%, the maximum COD removal rate was 60.5%. Free-radical quenching experiments showed that OH oxidation played a dominant role in the Ni-Mn@KL-catalyzed ozone-oxidation system, and the reaction system conformed to the second-order reaction kinetics law. Ni-Mn@KL catalysts were further confirmed to have good catalytic performance and mechanical performance after repeated utilization. PRACTITIONER POINTS: Ni-Mn@KL catalyst can achieve effective treatment of RO film concentrated liquid. High COD removal rate of RO membrane concentrated liquid was obtained at low cost. Ni-Mn@KL catalyst promotes ozone decomposition to produce ·OH and O2 -· oxidized organic matter. The Ni-Mn@KL catalyst can maintain good stability after repeated use. A CRITIC weight-coupling coordination model was established to evaluate the catalytic ozonation.

    We aimed to obtain the optimal formula for human milk fat substitute (HMFS) through a combination of software and an evaluation model and further verify its practicability through an animal experiment. The results showed that a total of 33 fatty acid (FA) and 63 triglyceride (TAG) molecular species were detected in vegetable oils. Palmitic acid, oleic acid, linoleic acid, 18:1/16:0/18:1, 18:2/16:0/18:2, 18:1/18:1/18:1 and 18:1/18:2/18:1, were the main molecular species among the FAs and TAGs in the vegetable oils. Based on the HMFS evaluation model, the optimal mixed vegetable oil formula was blended with 21.3% palm oil, 2.8% linseed oil, 2.6% soybean oil, 29.9% rapeseed oil and 43.4% maize oil, with the highest score of 83.146. Moreover, there was no difference in the weight, blood routine indices or calcium and magnesium concentrations in the feces of the mice between the homemade mixed vegetable oil (HMVO) group and the commercial mixed vegetable oil (CMVO) group, while nervonic acid (C24:1) and octanoic acid (C8:0) were absorbed easily in the HMVO group. Therefore, these results demonstrate that the mixing of the different vegetable oils was feasible via a combination of computer software and an evaluation model and provided a new way to produce HMFS.

    越来越多的建筑和拆除废物(CDW)已成为全球环境议程上的一个突出挑战。然而,CDW管理(CDWM)策略的有效性因城市而异。现有文献主要评估CDWM在项目层面的有效性,提供本地化视角,无法捕获城市的全面CDWM配置文件。这种局部聚焦具有某些局限性。为了填补城市规模评估的这一空白,这项研究引入了一种新的模型来评估市一级的CDWM有效性。在粤港澳大湾区(GBA)内的11个城市进行了实证调查,以实施该模型。该模型定义了CDWM有效性的五个不同级别。调查结果显示,香港一贯达到最高水平(一级),而大多数城市属于三级和四级。这种模式表明CDWM在GBA中的有效性是适度发展的,CDW管理成果和支持系统的进展不平衡。本质上,缺乏CDWM结果和保障体系的同步开发。拟议的评估模型丰富了现有的CDWM研究领域,并提供了一个框架,可以为其他国家的未来研究提供信息。
    The growing generation of construction and demolition waste (CDW) has emerged as a prominent challenge on global environmental agendas. However, the effectiveness of CDW management (CDWM) strategies varies among cities. Existing literature predominantly evaluates the effectiveness of CDWM at the project level, offering a localized perspective that fails to capture a city\'s comprehensive CDWM profile. This localized focus has certain limitations. To fill this gap in city-scale evaluations, this study introduces a novel model for assessing CDWM effectiveness at the municipal level. An empirical investigation was conducted across 11 cities within the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) to operationalize this model. The model defines five distinct levels of CDWM effectiveness. Findings indicate that Hong Kong consistently achieves the highest level (level I), while the majority of cities fall within levels III and IV. This pattern suggests that CDWM effectiveness in the GBA is moderately developed, with uneven progress in CDW management outcomes and supporting systems. Essentially, there is a lack of synchronous development of CDWM results and guarantee systems. The proposed evaluation model enriches existing CDWM research field and offers a framework that may inform future studies in other countries.
