    骨科手术后,比如髋关节置换,许多患者容易发生深静脉血栓(DVT),在严重的情况下可能导致致命的肺栓塞或大出血。大剂量抗凝治疗的临床干预不可避免地会带来出血的风险。因此,靶向药物递送系统,调整局部DVT病变,并潜在地减少药物剂量和毒副作用。在这项研究中,我们开发了用于DVT治疗的靶向药物递送血小板衍生纳米平台(AMSNP@PM-rH/A),可以同时递送直接凝血酶抑制剂(DTI)重组水蛭素(rH),和因子Xa抑制剂阿哌沙班(A)通过利用氨基化介孔二氧化硅纳米颗粒(AMSNP)。该制剂表现出改善的生物相容性和血液半衰期,并且可以有效地消除深静脉血栓形成病变,并以一半的剂量实现治疗效果。此外,我们采用各种可视化技术来捕获深静脉血栓形成中血小板膜(PM)涂层的靶向积累和释放,并探索其潜在的靶向机制.
    After orthopedic surgeries, such as hip replacement, many patients are prone to developing deep vein thrombosis (DVT), which in severe cases can lead to fatal pulmonary embolism or major bleeding. Clinical intervention with high-dose anticoagulant therapy inevitably carries the risk of bleeding. Therefore, a targeted drug delivery system that adjusts local DVT lesions and potentially reduces drug dosage and toxic side effects important. In this study, we developed a targeted drug delivery platelet-derived nanoplatform (AMSNP@PM-rH/A) for DVT treatment that can simultaneously deliver a direct thrombin inhibitor (DTI) Recombinant Hirudin (rH), and the Factor Xa inhibitor Apixaban (A) by utilizing Aminated mesoporous silica nanoparticles (AMSNP). This formulation exhibits improved biocompatibility and blood half-life and can effectively eliminate deep vein thrombosis lesions and achieve therapeutic effects at half the dosage. Furthermore, we employed various visualization techniques to capture the targeted accumulation and release of a platelet membrane (PM) coating in deep vein thrombosis and explored its potential targeting mechanism.

    眼手协调(EHC)对我们的日常活动至关重要,及其潜在机制正在被深入研究。对同时的眼睛和手运动的分析可以为EHC提供有价值的见解,特别是对于那些在灵巧控制中挣扎的人来说,例如可能由中风或创伤性脑损伤引起。尽管运动捕捉和眼动追踪技术取得了进步,目前还没有用于同时可视化眼睛和手移动数据的自动化方法。为了满足这一需求,我们开发了一个基于MATLAB的仪表板,用于眼睛和手跟踪数据的近瞬时分析和可视化。本文介绍了仪表板的设计,并给出了从其应用中获得的实验结果,利用受我们最近中风研究启发的模拟数据。该测试表明,我们的解决方案有可能通过提供眼睛/手运动的并排和时间锁定比较以及它们的时间和时空误差来显著帮助理解和研究EHC。为研究和临床应用提供新的机会。•在整个实验中收集连续的眼动数据•在整个实验中收集连续的手部运动数据•组合数据集并在单个仪表板中显示时间锁定的眼手数据。
    Eye-hand coordination (EHC) is crucial to our daily activities, and its underlying mechanisms are being intensely studied. The analysis of simultaneous eye and hand movements can provide valuable insights into EHC, particularly for individuals struggling with dexterous control, such as might be caused by stroke or traumatic brain injuries. Despite advancements in motion-capture and eye tracking technologies, there is currently no automated method for visualizing concurrent eye- and hand-movement data. To address this need, we have developed a MATLAB-based dashboard designed for near instantaneous analysis and visualization of eye and hand-tracking data. This paper introduces the design of the dashboard and presents experimental results obtained from its application, leveraging simulated data inspired by our recent work in stroke. This testing suggests that our solution has the potential to significantly aid in understanding and investigating EHC by providing side-by-side and time-locked comparison of eye/hand movements along with their timing and spatio-temporal errors, offering novel opportunities for research and clinical applications.•Continuous eye movement data is collected throughout the experiment•Continuous hand movement data is collected throughout the experiment•Combine datasets and display time-locked eye-hand data in a single dashboard.

    如今,机器人在越来越多的领域被发现,它们与人类紧密合作。由轻质材料和安全传感器启用,这些合作机器人在家庭护理中越来越受欢迎,他们在日常生活中支持身体受损的人。然而,当协作机器人自主执行动作时,人类合作者理解和预测他们的行为仍然具有挑战性,这对于实现信任和用户接受至关重要。预测协作机器人行为的一个重要方面是理解他们的感知并理解他们如何“看待”世界。为了应对这一挑战,我们比较了三种不同的空间增强现实可视化技术。所有这些都通过视觉上指示协作机器人周围的哪些物体已被其传感器识别来传达协作机器人的感知。我们将完善的可视化Wedge和Halo与我们提出的可视化Line在远程用户实验中进行了比较,参与者患有身体损伤。在第二个远程实验中,我们使用更广泛的非特定用户群验证了这些发现.我们的发现表明Line,复杂性较低的可视化,与Halo相比,反应时间明显加快,与楔形和光晕相比,任务负载更低。总的来说,用户更喜欢Line作为更直接的可视化。在空间增强现实中,由于其已知的投影面积有限的缺点,建立的屏幕外可视化不能有效地传达协作机器人的感知,而Line提供了一个易于理解的替代方案。
    Nowadays, robots are found in a growing number of areas where they collaborate closely with humans. Enabled by lightweight materials and safety sensors, these cobots are gaining increasing popularity in domestic care, where they support people with physical impairments in their everyday lives. However, when cobots perform actions autonomously, it remains challenging for human collaborators to understand and predict their behavior, which is crucial for achieving trust and user acceptance. One significant aspect of predicting cobot behavior is understanding their perception and comprehending how they \"see\" the world. To tackle this challenge, we compared three different visualization techniques for Spatial Augmented Reality. All of these communicate cobot perception by visually indicating which objects in the cobot\'s surrounding have been identified by their sensors. We compared the well-established visualizations Wedge and Halo against our proposed visualization Line in a remote user experiment with participants suffering from physical impairments. In a second remote experiment, we validated these findings with a broader non-specific user base. Our findings show that Line, a lower complexity visualization, results in significantly faster reaction times compared to Halo, and lower task load compared to both Wedge and Halo. Overall, users prefer Line as a more straightforward visualization. In Spatial Augmented Reality, with its known disadvantage of limited projection area size, established off-screen visualizations are not effective in communicating cobot perception and Line presents an easy-to-understand alternative.

    There is a growing understanding that cross-sector risks faced by critical infrastructure assets in natural disasters require a collaborative foresight from multiple disciplines. However, current contributions to infrastructure interdependency analysis remain centered in discipline-specific methodologies often constrained by underlying theories and assumptions. This perspective article contributes to ongoing discussions about the uses, challenges, and opportunities provided by interdisciplinary research in critical infrastructure interdependency analysis. In doing so, several modes of integration of computational modeling with contributions from the social sciences and other disciplines are explored to advance knowledge that can improve the infrastructure system resilience under extreme events. Three basic modes of method integration are identified and discussed: (a) integrating engineering models and social science research, (b) engaging communities in participative and collaborative forms of social learning and problem solving using simulation models to facilitate synthesis, exploration, and evaluation of scenarios, and (c) developing interactive simulations where IT systems and humans act as \"peers\" leveraging the capacity of distributed networked platforms and human-in-the-loop architectures for improving situational awareness, real-time decision making, and response capabilities in natural disasters. Depending on the conceptualization of the issues under investigation, these broadly defined modes of integration can coalesce to address key issues in promoting interdisciplinary research by outlining potential areas of future inquiry that would be most beneficial to the critical infrastructure protection communities.
