    评估土地质量是土地利用规划和管理决策之前非常重要的一步;例如,在农业领域,它可以用来评估土地种植作物的适宜性,确定合适的灌溉系统类型,或根据土地上每个区域的要求调整化肥和农药等农业投入。土地特征的时空动态性质还需要更新的评估过程和更新的管理计划。本文试图利用信息和通信技术的进步来开发动态系统的概念设计,该系统适应农业土壤特征的时空动态,以实现基于因子分析的土地适宜性评估(LSA)方法。拟议的设计结合了物联网技术,web开发,数据库,和数字制图,并试图将该系统与其他对决策支持有用并适用于不同情况的功能合并在一起。本文进行了调查并进行了比较,以选择适合当前用例实现的最佳技术,并通过通过模式开发静态和动态视图来提出其可重复的概念建模,图表,消息序列图,IoT消息传递主题树,伪代码,等。通过系统模型的简单实现,验证了设计的功能。据我们所知,以前没有针对LSAIoT用例的重大贡献。拟议的设计使LSA过程自动化,以实现更准确的决策,节约成本,时间,在反复的实地考察中消耗的精力。它的特点是空间分析服务的灵活性和集中性,检测,可视化,和状态监测。该设计还允许远程控制现场机械。
    Assessing the quality of land is a very important step that precedes the planning of land use and taking management decisions; for example, in the agricultural field, it can be used to evaluate the suitability of the land for planting crops, determine the suitable irrigation system type, or adjust the agricultural inputs such as fertilizers and pesticides according to the requirements of each zone in the land. The spatial-temporal dynamic nature of land characteristics entails also updated evaluation process and updated management plan. The present paper tries to exploit the advances in information and communication technologies to develop a conceptual design of a dynamic system that accommodates the spatial-temporal dynamics of the agricultural soil characteristics to realize a land suitability assessment (LSA) based on a factor analysis method. The proposed design combines IoT technologies, web development, database, and digital mapping and tries to consolidate the system with other functionalities useful for decision support and suitable for different cases. The paper conducted a survey and made comparisons to select the best technologies that fit the current use case implementation and presents its reproducible conceptual modeling by developing the static and dynamic views through schemas, diagrams, message sequence charts, IoT messaging topic tree, pseudocode, etc. The functionality of the design was validated with a simple implementation of the system model. To our knowledge, there is no previous significant contribution that has addressed a LSA IoT use case. The proposed design automates the LSA process for more accurate decision-making, saving cost, time, and effort consumed in repeated field trips. It is characterized by flexibility and centralization in its offered services of spatial analysis, detection, visualizations, and status monitoring. The design also allows for remote control of field machinery.

    背景:特应性皮炎(AD)的全身性免疫学治疗选择的快速扩展已经为患者和临床医生创造了对临床相关且可理解的比较疗效和安全性信息的需求。鉴于头对头试验的稀缺性,网络荟萃分析(NMA)是一种在治疗方案之间进行稳健比较的替代方法;然而,NMA结果通常很复杂,难以在共同决策中直接实施。
    目的:本研究的目的是开发一个网站,有效地向患者和临床医生用户介绍有关AD治疗的实时系统评价和NMA的结果。
    方法:我们使用来自成人AD的迭代反馈进行了多方法研究,患有AD的儿童的成人看护者,皮肤科医生,和以用户为中心的设计框架内的过敏原。我们使用问卷调查,然后在患者和临床医生中进行研讨会,以开发和改进网站界面。可用性测试是与湿疹患者的护理人员一起进行的。
    结果:问卷由31名患有AD的成年人或护理人员和94名临床医生完成。患者和护理人员认为了解新疗法非常重要(20/31,65%)。临床医生认为缺乏基于证据的比较治疗是护理的障碍(55/93,59%)。“避免危险的副作用”被列为患者最重要的优先事项(加权排名5.2/7,排名越高越重要),“改善患者的整体症状”是临床医生最重要的优先事项(加权排序5.0/6)。共有4名患者和7名临床医生参加了研讨会;他们赞赏NMA结果的可视化,并发现该网站对于比较不同的治疗方法很有价值。患者建议进行更改以简化界面并澄清与比较疗效相关的术语。用户在可用性测试中发现网站导航直观。
    结论:我们开发了一个网站,\"eczematherapies.com,以用户为中心的设计方法。NMA结果的可视化使用户能够将治疗方法作为其共享决策过程的一部分进行比较。
    BACKGROUND: A rapid expansion of systemic immunological treatment options for atopic dermatitis (AD) has created a need for clinically relevant and understandable comparative efficacy and safety information for patients and clinicians. Given the scarcity of head-to-head trials, network meta-analysis (NMA) is an alternative way to enable robust comparisons among treatment options; however, NMA results are often complex and difficult to directly implement in shared decision-making.
    OBJECTIVE: The aim of this study is to develop a website that effectively presents the results of a living systematic review and NMA on AD treatments to patient and clinician users.
    METHODS: We conducted a multimethod study using iterative feedback from adults with AD, adult caregivers of children with AD, dermatologists, and allergists within a user-centered design framework. We used questionnaires followed by workshops among patients and clinicians to develop and improve the website interface. Usability testing was done with a caregiver of a patient with eczema.
    RESULTS: Questionnaires were completed by 31 adults with AD or caregivers and 94 clinicians. Patients and caregivers felt it was very important to know about new treatments (20/31, 65%). Clinicians felt the lack of evidence-based comparisons between treatments was a barrier to care (55/93, 59%). \"Avoiding dangerous side effects\" was ranked as the most important priority for patients (weighted ranking 5.2/7, with higher ranking being more important), and \"improving patients\' overall symptoms\" was the most important priority for clinicians (weighted ranking 5.0/6). A total of 4 patients and 7 clinicians participated in workshops; they appreciated visualizations of the NMA results and found the website valuable for comparing different treatments. The patients suggested changes to simplify the interface and clarify terminology related to comparative efficacy. The user in the usability testing found the website intuitive to navigate.
    CONCLUSIONS: We developed a website, \"eczematherapies.com,\" with a user-centered design approach. Visualizations of NMA results enable users to compare treatments as part of their shared decision-making process.

    人工智能(AI)已被广泛引入各种医学成像应用,从疾病可视化到医疗决策支持。然而,数据隐私已成为通过云计算部署深度学习算法的临床实践中必不可少的问题。患者健康信息(PHI)的敏感性通常会限制网络传输,安装定制桌面软件,以及对计算资源的访问。无服务器边缘计算揭示了隐私保护模型分布,同时保持了高灵活性(作为云计算)和安全性(作为本地部署)。在本文中,我们提出了一个基于浏览器的,跨平台,和隐私保护的医疗成像AI部署系统通过无服务器边缘计算在消费者级别的硬件上工作。简而言之,我们通过部署用于基于计算机断层扫描(CT)的肺癌筛查的3D医学图像分割模型来实现此系统。我们通过表征速度,进一步在模型复杂性和数据大小方面进行权衡,内存使用情况,以及各种操作系统和浏览器的限制。我们的实现实现了(1)在CT体积(256×256×256分辨率)上使用3D卷积神经网络(CNN)的部署,(2)Firefoxv.102.0.1/Chromev.103.0.5060.114/MicrosoftEdgev.103.0.1264.44的平均运行时间为80秒,Safariv.14.1.1的平均运行时间为210秒,以及(3)MicrosoftWindows笔记本电脑的平均内存使用量为1.5GB,Linux工作站,和苹果Mac笔记本电脑。总之,这项工作为医学成像AI应用程序提供了一种保护隐私的解决方案,可将PHI暴露的风险降至最低。我们描述了工具的特征,架构,以及我们框架的参数,以促进将现代深度学习方法转化为常规临床护理。
    Artificial intelligence (AI) has been widely introduced to various medical imaging applications ranging from disease visualization to medical decision support. However, data privacy has become an essential concern in clinical practice of deploying the deep learning algorithms through cloud computing. The sensitivity of patient health information (PHI) commonly limits network transfer, installation of bespoke desktop software, and access to computing resources. Serverless edge-computing shed light on privacy preserved model distribution maintaining both high flexibility (as cloud computing) and security (as local deployment). In this paper, we propose a browser-based, cross-platform, and privacy preserved medical imaging AI deployment system working on consumer-level hardware via serverless edge-computing. Briefly we implement this system by deploying a 3D medical image segmentation model for computed tomography (CT) based lung cancer screening. We further curate tradeoffs in model complexity and data size by characterizing the speed, memory usage, and limitations across various operating systems and browsers. Our implementation achieves a deployment with (1) a 3D convolutional neural network (CNN) on CT volumes (256×256×256 resolution), (2) an average runtime of 80 seconds across Firefox v.102.0.1/Chrome v.103.0.5060.114/Microsoft Edge v.103.0.1264.44 and 210 seconds on Safari v.14.1.1, and (3) an average memory usage of 1.5 GB on Microsoft Windows laptops, Linux workstation, and Apple Mac laptops. In conclusion, this work presents a privacy-preserved solution for medical imaging AI applications that minimizes the risk of PHI exposure. We characterize the tools, architectures, and parameters of our framework to facilitate the translation of modern deep learning methods into routine clinical care.

    当前的程序术语代码是一种数字编码系统,用于为医疗程序和服务开具账单,代表了主要的报销途径。鉴于病理服务是医院收入的相应来源,了解代码可能被错误分配或欠费的情况是至关重要的。已经提出了几种算法,可以在现有的病理报告数据集中识别不正确的计费CPT代码。估计这些报告的财政影响需要一个编码器(即,计费人员)来查看原始报告并再次手动编码。由于使用机器学习算法可以快速完成代码的重新分配,验证这些重新分配的瓶颈是在手动重新编码过程中,这可以证明是麻烦的。这项工作记录了可快速部署的仪表板的开发,用于检查原始编码器可能有错误计费的报告。我们的仪表板具有以下主要组件:(1)条形图显示每个CPT代码的预测概率,(2)解释图,显示报告中的每个单词如何组合以形成整体预测,和(3)用户输入他们选择分配的CPT代码的地方。该仪表板利用开发的算法来准确地识别CPT代码以突出显示原始编码器错过的代码。为了演示此Web应用程序的功能,我们招募了病理学家,利用它来突出显示错误分配代码的报告。我们希望此应用程序通过促进快速审查假阳性病理报告来加速重新分配代码的验证。在未来,我们将使用这项技术来审查过去的数千个案例,以估计账单不足对部门收入的影响。
    Current Procedural Terminology Codes is a numerical coding system used to bill for medical procedures and services and crucially, represents a major reimbursement pathway. Given that pathology services represent a consequential source of hospital revenue, understanding instances where codes may have been misassigned or underbilled is critical. Several algorithms have been proposed that can identify improperly billed CPT codes in existing datasets of pathology reports. Estimation of the fiscal impacts of these reports requires a coder (i.e., billing staff) to review the original reports and manually code them again. As the re-assignment of codes using machine learning algorithms can be done quickly, the bottleneck in validating these reassignments is in this manual re-coding process, which can prove cumbersome. This work documents the development of a rapidly deployable dashboard for examination of reports that the original coder may have misbilled. Our dashboard features the following main components: (1) a bar plot to show the predicted probabilities for each CPT code, (2) an interpretation plot showing how each word in the report combines to form the overall prediction, and (3) a place for the user to input the CPT code they have chosen to assign. This dashboard utilizes the algorithms developed to accurately identify CPT codes to highlight the codes missed by the original coders. In order to demonstrate the function of this web application, we recruited pathologists to utilize it to highlight reports that had codes incorrectly assigned. We expect this application to accelerate the validation of re-assigned codes through facilitating rapid review of false-positive pathology reports. In the future, we will use this technology to review thousands of past cases in order to estimate the impact of underbilling has on departmental revenue.

    在COVID-19大流行期间,越来越需要描述这种疾病的特征。一个非常重要的方面是测量免疫程度的能力,这可以使用定量测量COVID相关抗体存在的抗原微阵列来实现。这些测试的一个重要限制是手动分析结果的复杂性,以及用于其分析的软件可用性有限。在本文中,我们描述了COVID-BIOCHIP的发展,一种基于网络的临时解决方案,用于自动分析和可视化COVID-19抗原微阵列数据结果。
    During the COVID-19 pandemic, there was a growing need to characterise the disease. A very important aspect is the ability to measure the immunisation extent, which can be achieved using antigen microarrays that quantitively measure the presence of COVID-related antibodies. A significant limitation for these tests was the complexity of manually analysing the results, and the limited availability of software for its analysis. In this paper, we describe the development of COVID-BIOCHIP, an ad-hoc web-based solution for the automatic analysis and visualisation of COVID-19 antigen microarray data results.

    居民接受培训的时间有限。虽然案件数量变化很大,但对住院医师培训应该是有益的,居民不一定能得到均匀分布的案件。通过开发一个仪表板,居民和他们的出席者可以跟踪他们所做的程序和他们所看到的案例,我们希望让居民对他们的培训有更深入的了解,以及他们培训中可能出现的差距。通过利用NLP技术的现代进步,我们处理医疗记录并生成统计数据,描述到目前为止每个居民的进展。我们已经在NYP生态系统中建立了所描述的系统及其生命。通过创建更好的跟踪,我们希望可以改变工作量,以更好地缩小培训方面的任何差距。放射学住院医师的教育痛点之一是分配病例以匹配均衡的课程。通过阐明居民的历史案例,我们可以更好地分配未来的案例,以获得更好的教育体验。
    Residents have a limited time to be trained. Although having a highly variable caseload should be beneficial for resident training, residents do not necessarily get a uniform distribution of cases. By developing a dashboard where residents and their attendings can track the procedures they have done and cases that they have seen, we hope to give residents a greater insight into their training and into where gaps in their training may be occurring. By taking advantage of modern advances in NLP techniques, we process medical records and generate statistics describing each resident\'s progress so far. We have built the system described and its life within the NYP ecosystem. By creating better tracking, we hope that caseloads can be shifted to better close any individual gaps in training. One of the educational pain points for radiology residency is the assignment of cases to match a well-balanced curriculum. By illuminating the historical cases of a resident, we can better assign future cases for a better educational experience.

    背景:高通量转录组研究的一个主要挑战是将数据以可解释的格式呈现给研究人员。在许多情况下,这些研究的输出是基因列表,然后检查丰富的生物学概念。帮助研究人员解释大型基因数据集的一种方法是使用eGIFT文本挖掘系统将从生物医学文献中获得的基因和信息术语(iTerm)相关联。然而,检查iTerm和基因对的大型列表是一项艰巨的任务。
    结果:我们开发了WebGIVI,基于Web的交互式可视化工具(http://raven。anr.udel.edu/webgivi/)探索基因:iTerm对。WebGIVI是通过Cytoscape和数据驱动文档JavaScript库构建的,可用于将基因与iTerms联系起来,然后可视化基因和iTerm对。WebGIVI可以接受用于检索基因符号的基因列表和相应的iTerm列表。可以提交此列表以使用两种不同的方法可视化基因iTerm对:概念图或Cytoscape网络图。此外,WebGIVI还支持上传和可视化任何两列标签分隔的数据。
    结论:WebGIVI提供了基因和iTerms的交互式集成网络图,允许过滤,排序,和分组,这可以帮助生物学家根据输入的基因列表发展假设。此外,WebGIVI可以可视化数百个节点并生成高分辨率图像,这对大多数研究出版物都很重要。源代码可以在https://github.com/sunliang3361/WebGIVI免费下载。WebGIVI教程可在http://raven获得。anr.udel.edu/webgivi/tutorial.php。
    BACKGROUND: A major challenge of high throughput transcriptome studies is presenting the data to researchers in an interpretable format. In many cases, the outputs of such studies are gene lists which are then examined for enriched biological concepts. One approach to help the researcher interpret large gene datasets is to associate genes and informative terms (iTerm) that are obtained from the biomedical literature using the eGIFT text-mining system. However, examining large lists of iTerm and gene pairs is a daunting task.
    RESULTS: We have developed WebGIVI, an interactive web-based visualization tool ( http://raven.anr.udel.edu/webgivi/ ) to explore gene:iTerm pairs. WebGIVI was built via Cytoscape and Data Driven Document JavaScript libraries and can be used to relate genes to iTerms and then visualize gene and iTerm pairs. WebGIVI can accept a gene list that is used to retrieve the gene symbols and corresponding iTerm list. This list can be submitted to visualize the gene iTerm pairs using two distinct methods: a Concept Map or a Cytoscape Network Map. In addition, WebGIVI also supports uploading and visualization of any two-column tab separated data.
    CONCLUSIONS: WebGIVI provides an interactive and integrated network graph of gene and iTerms that allows filtering, sorting, and grouping, which can aid biologists in developing hypothesis based on the input gene lists. In addition, WebGIVI can visualize hundreds of nodes and generate a high-resolution image that is important for most of research publications. The source code can be freely downloaded at https://github.com/sunliang3361/WebGIVI . The WebGIVI tutorial is available at http://raven.anr.udel.edu/webgivi/tutorial.php .

    在过去的十年中,通过网络获得的植物生物多样性数据的数量激增,但是要获得这些数据需要大量的时间和工作投入,对于希望验证这些在线作品的影响因素的组织和机构来说,这两个都是至关重要的考虑因素。在这里,我们使用了谷歌分析(GA),来衡量这个数字存在的价值。在本文中,我们使用15个不同的GA帐户检查使用趋势,分布在451个机构或植物项目,占世界草药的5%以上。他们在一年和一年中都进行了研究。样本中的用户数据显示:1)超过1700万个网络会话,2)在五个主要操作系统上,3)搜索和直接流量占主导地位,社交媒体的影响最小,4)在过去三年中,移动和新设备类型每年翻了一番,5)和Web浏览器,我们用来与网络互动的工具,正在改变。服务器端分析因站点而异,因此很难比较其数据集。然而,使用GoogleAnalytics消除了独特服务器端分析的报告异构性,因为现在可以用一个为数据驱动的决策提供清晰的标准来检查它们。这里获得的知识赋予任何基于集合的环境,无论大小,关于可用性的指标,设计,以及未来发展的可能方向。
    The amount of plant biodiversity data available via the web has exploded in the last decade, but making these data available requires a considerable investment of time and work, both vital considerations for organizations and institutions looking to validate the impact factors of these online works. Here we used Google Analytics (GA), to measure the value of this digital presence. In this paper we examine usage trends using 15 different GA accounts, spread across 451 institutions or botanical projects that comprise over five percent of the world\'s herbaria. They were studied at both one year and total years. User data from the sample reveal: 1) over 17 million web sessions, 2) on five primary operating systems, 3) search and direct traffic dominates with minimal impact from social media, 4) mobile and new device types have doubled each year for the past three years, 5) and web browsers, the tools we use to interact with the web, are changing. Server-side analytics differ from site to site making the comparison of their data sets difficult. However, use of Google Analytics erases the reporting heterogeneity of unique server-side analytics, as they can now be examined with a standard that provides a clarity for data-driven decisions. The knowledge gained here empowers any collection-based environment regardless of size, with metrics about usability, design, and possible directions for future development.
