纳米粒子可提高电池能量密度,满足电动汽车续航要求。在莫妮卡驾驶电动汽车前往母亲家的路上,电池电量显示该充电了。她在一个充电站停下来,在泵上刷了一下信用卡,然后将管口插入汽车,用了5分钟的时间,将400升已耗尽电量的纳米流体换成新的液体。在她等待的时候,一辆罐车停了下来给充电站补充燃料,用数万升已充电燃料替换电量已耗尽的燃料。

We are evaluating dryland cotton production in Martin County, Texas, measuring cotton lint yield per unit of rainfall. Our goal is to collect rainfall data per 250 - 400 ha. Upon selection of a rainfall gauge, we realized that the cost of using, for example, a tipping bucket-type rain gauge would be too expensive and thus searched for an alternative method. We selected an all-in-one commercially available weather station;hereafter, referred to as a Personal Weather Station (PWS) that is both wireless and solar powered. Our objective was to evaluate average measurements of rainfall obtained with the PWS and to compare these to measurements obtained with an automatic weather station (AWS). For this purpose, we installed four PWS deployed within 20 m of the Plant Stress and Water Conservation Meteorological Tower that was used as our AWS, located at USDA-ARS Cropping Systems Research Laboratory, Lubbock, TX. In addition, we measured and compared hourly average values of short-wave irradiance (Rg), air temperature (Tair) and relative humidity (RH), and wind speed (WS), and calculated values of dewpoint temperature (Tdew). This comparison was done over a 242-day period (1 October 2022-31 May 2023) and results indicated that there was no statistical difference in measurements of rainfall between the PWS and AWS. Hourly average values of Rg measured with the PWS and AWS agreed on clear days, but PWS measurements were higher on cloudy days. There was no statistical difference between PWS and AWS hourly average measurements of Tair, RH, and calculated Tdew. Hourly average measurements of Rg and WS were more variable. We concluded that the PWS we selected will provide adequate values of rainfall and other weather variables to meet our goal of evaluating dryland cotton lint yield per unit rainfall.

条锈病是世界范围内小麦上的重要病害，培育和种植抗病品种是防治条锈病最经济有效的措施。为明确澳大利亚小麦材料的抗条锈病水平及所含抗条锈病基因，本研究利用8个澳大利亚小麦条锈菌流行小种对121份小麦材料进行了苗期抗性鉴定，同时应用小麦抗条锈病基因Yr5、Yr9 (1B/1R)、Yr10、Yr15、Yr17及Yr26的特异性分子标记进行了分子检测。结果表明，121份小麦材料中，21份(17.35%)对所有供试条锈菌小种均表现抗病，7份(5.79%)均表现感病，其他材料对一个或多个条锈菌小种表现抗病。分子检测结合抗病性鉴定结果显示，3份(2.48%)可能含有Yr5基因，15份(12.40%)可能含有Yr9,9份(7.44%%)可能含有Yr10,6份(4.96%)可能含有Yr17,19份(15.70%)可能含有Yr26，没有检测到Yr15基因。此外，其中13份材料同时检测到两个或两个以上的抗条锈病基因，还有19份材料可能含有其他已知或未知的抗条锈基因。本研究为121份澳大利亚小麦材料的合理利用和小麦抗病育种提供了科学依据。

在碳纤维增强树脂基复合材料轻量化与结构性能持续提高的前提下，同时附加其特定的功能，尤其是在不损失、甚至提升其层间断裂韧性的情况下，不仅可以弥补结构复合材料天然的缺陷，例如树脂基体的电绝缘性，也可以使其满足特定产品的要求，例如高刚度兼具一定的吸声降噪特性等。显然，对于航空航天这样的尖端应用领域，这种功能附加或结构功能一体化的复合材料技术对航空航天技术的未来发展至关重要。本文介绍了4种具有典型性的结构功能一体化复合材料的设计、制备与性能研究，分别是基于层间功能化插层和基于内织导电纬纱的导电增韧一体化复合材料及多级孔碳化棉纤维填充蜂窝/微穿孔面板的夹芯复合材料结构和编织布/无纺纤维毡复合材料片材折叠成型的结构吸声一体化复合材料。前两种材料分别通过在复合材料富树脂的层间插入导电功能化插层和在复合材料内引入贯通整个材料的导电纬纱网络实现了复合材料的导电性能与层间韧性的同步提高，而后两种材料则分别通过多级孔结构的碳化棉纤维材料填充蜂窝/微穿孔面板夹芯技术和编织布/无纺纤维毡复合材料片材的折叠技术实现了良好的吸声性能等，以展示多尺度、多层次结构设计和制备技术在结构复合材料功能化集成和结构功能一体化方面的应用。

BACKGROUND The sphericity of the femoral head is a metric used to evaluate hip pathologies and is associated with the development of osteoarthritis and femoral-acetabular *** To analyze the three-dimensional asphericity of the femoral head of asymptomatic pediatric *** hypothesized that femoral head asphericity will vary significantly between male and female pediatric hips and increase with age in both *** Computed tomography scans were obtained on 158 children and adolescents from a single institution in the United States(8-18 years;50%male)without hip *** femoral measurements including the femoral head diameter,femoral head volume,residual volume,asphericity index,and local diameter difference were used to evaluate femoral head *** In both sexes,the residual volume increased by age(P13 years)in females,there were no sex-differences in residual volume and aspherity *** were no age-related changes in mean diameter difference in both sexes(P=0.07)with no significant sex-differences across different age groups(P=0.06).In contrast,there were significant increases in local aspherity(maximum diameter difference)across whole surface of the femoral head and all quadrants except the inferior regions in males(P=0.03).There were no sex-differences in maximum diameter difference at any regions and age group(P>0.05).Increased alpha angle was only correlated to increased mean diameter difference across overall surface of the femoral head(P=0.024).CONCLUSION There is a substantial localized asphericity in asymptomatic hips which increases with age *** 2D measured alpha angle can capture overall asphericity of the femoral head,it may not be sensitive enough to represent regional asphericity patterns.

Introduction: One in two cardiac patients fear having another heart event or their heart condition getting worse. Research in other chronic illnesses demonstrates that screening for fear of progression and recurrence is vital for adequately addressing such concerns in clinical care. The current project aims to develop and validate a measure for fear of progression and recurrence in cardiac ***: The Fear of Cardiac Recurrence and Progression Scale (FCRP) will be developed through a multistep process. An initial item pool will be generated through a review of the literature and existing measures and consultation with and feedback from key informants. The item pool will be tested in a sample of over 250 adults who have ever had an acute coronary event, undergone cardiac surgery, or a chronic cardiac condition. Exploratory factor analysis will be used to identify the underlying factors, and Rasch analysis will be used to reduce the number of items. A short form version of the FCRP will be developed for use as a brief screening tool, informed by clinical relevance and Rasch psychometric ***: While many cardiac patients experience fears related to the progression or recurrence of their illness, there remains the need for a validated tool with which these concerns can be identified and measured. It is expected that the design and validation of the FCRP will aid identification of cardiac patients suffering from clinically significant levels of fear of progression and recurrence and facilitate the design of tailored psychological interventions to target these fears.

《荀子·天论》至少包含三种不同的天论.首先,天为无目的、无规范性的自然之天.这种理论与自然化观点相呼应,后者主张作为自然的天不可能是伦理规则的来源,伦理规则只能是在非自然的礼中找到.其次,天是有明确规范性的自然.这一理论把天看作是人制作伦理区分和创作礼序能力的自然之根.在回应自然主义的挑战方面与之前的理论不同,它采取的方式是,试图将人类礼仪与前人类形式的生物性相调和,后者对自然主义而言,必定是人类价值的终极来源.最后,"天"的使用并非在自然意义上,存在一种如上帝、命运或礼之序的直接根据的内涵.《荀子》,如同其它早期儒家文本一样,并非意在形成一贯的形上哲学理论.有关天的所有探讨,天都不是重点,主要意图是礼的合法化.不管天是被描绘为无目的的自然、规范性的自然力量、命运、还是有目的的神,它的工具性作用都是一样的:将礼仪形式、礼之学习、和礼仪社会合法化.

Background Clonorchiasis and opisthorchiasis, caused by the liver flukesClonorchis sinensis andOpisthorchis viverrini respectively, represent significant neglected tropical diseases (NTDs) in Asia. The co-existence of these pathogens in overlapping regions complicates effective disease control strategies. This study aimed to clarify the distribution and interaction of these diseases within Southeast *** We systematically collated occurrence records of human clonorchiasis (n = 1809) and opisthorchiasis (n = 731) across the Southeast Asia countries. Utilizing species distribution models incorporating environmental and climatic data, coupled machine learning algorithms with boosted regression trees, we predicted and distinguished endemic areas for each fluke species. Machine learning techniques, including geospatial analysis, were employed to delineate the boundaries between these *** Our analysis revealed that the endemic range ofC. sinensis andO. viverrini in Southeast Asia primarily spans across part of China, Vietnam, Thailand, Laos, and Cambodia. During the period from 2000 to 2018, we identifiedC. sinensis infections in 84 distinct locations, predominantly in southern China (Guangxi Zhuang Autonomous Region) and northern Vietnam. In a stark contrast,O. viverrini was more widely distributed, with infections documented in 721 locations across Thailand, Laos, Cambodia, and Vietnam. Critical environmental determinants were quantitatively analyzed, revealing annual mean temperatures ranging between 14 and 20 °C in clonorchiasis-endemic areas and 24–30 °C in opisthorchiasis regions (P < 0.05). The machine learning model effectively mapped a distinct demarcation zone, demonstrating a clear separation between the endemic areas of these two liver flukes with AUC from 0.9 to1. The study in Vietnam delineates the coexistence and geographical boundaries ofC. sinensis andO. viverrini, revealing distinct endemic zones and a transitional area where both live
