Introduction

The WHO Global Action Plan for Poliovirus Containment, 4th edition (GAPIV) describes the necessary conditions for the containment of poliovirus material in poliovirus-essential facilities (PEFs). PEF status is achieved by successfully undergoing the process of certification by the Global Commission for the Certification of the Eradication of Poliomyelitis in compliance with GAPIV requirements. The GAPIV guidelines cover many topics, including waste management, decontamination, disinfection and sterilization. This element of GAPIV requires PEFs to demonstrate in-house validation of decontamination methods with supporting data.

Methods

The method used for validation of chemical products for poliovirus decontamination in this study was based on processes outlined in European Standard EN14476, as recommended by the WHO GAPIV guidelines. In this study, the disinfectants 5 % Microchem Plus and 1 % Virkon®S were evaluated for efficacy against high titre poliovirus in solutions with and without high organic load using an endpoint dilution assay. A poliovirus Sabin 1 strain was used as the reference virus with the titre 8.33 log10 CCID50 (50 % cell culture infectious dose) in 0.1 ml.

Results

The poliovirus titre after Microchem Plus treatment was calculated as 5.5 (representing a 2.8 CCID50 titre reduction), indicating only partial inactivation. In contrast, poliovirus in solutions with and without high organic load achieved >4 log10 CCID50 titre reduction (≥6.8 and ≥5.8 reduction respectively), after Virkon®S treatment. The Virkon®S treatment results were at the limit of detection of the endpoint dilution assay, indicating complete inactivation, or as near complete that can be demonstrated with the assay. The virus culture results were confirmed by a molecular assay for the detection of enterovirus RNA.

Conclusion

Microchem Plus only partially inactivated poliovirus and cannot be relied upon as the sole decontaminant. In contrast, Virkon®S performed well for both high titre poliovirus in solutions with and without high organic load, achieving >4 log10 titre reduction for both, making Virkon®S a suitable disinfectant for poliovirus.
世卫组织遏制脊髓灰质炎病毒全球行动计划第4版(GAPIV)描述了在脊髓灰质炎病毒基础设施(pef)中遏制脊髓灰质炎病毒材料的必要条件。通过成功地通过全球根除脊髓灰质炎认证委员会的认证程序,符合《全球根除脊髓灰质炎疫苗计划》的要求,才能获得PEF地位。GAPIV指南涵盖了许多主题,包括废物管理、去污、消毒和灭菌。GAPIV的这一要素要求pef用支持数据证明净化方法的内部验证。方法本研究中用于脊髓灰质炎病毒去污染化学产品验证的方法基于欧洲标准EN14476中概述的流程,并由世卫组织GAPIV指南推荐。在这项研究中,使用终点稀释法评估了消毒剂5% Microchem Plus和1% Virkon®S在有和没有高有机负荷的溶液中对高滴度脊髓灰质炎病毒的功效。以脊髓灰质炎病毒Sabin 1株为对照病毒,0.1 ml中CCID50滴度为8.33 log10(50%细胞培养感染剂量)。结果Microchem Plus处理后脊髓灰质炎病毒滴度为5.5 (CCID50滴度降低2.8),仅部分失活。相比之下,在具有和不具有高有机负荷的溶液中,脊髓灰质炎病毒在经过Virkon®S处理后,CCID50滴度降低了4 log10(分别降低≥6.8和≥5.8)。Virkon®S处理结果在终点稀释试验的检测极限,表明完全失活,或接近完全失活,可以用该试验证明。病毒培养结果通过检测肠道病毒RNA的分子试验得到证实。结论microchem Plus仅能部分灭活脊髓灰质炎病毒,不能作为唯一的去污剂。相比之下,Virkon®S在有和没有高有机负荷的溶液中对高滴度的脊髓灰质炎病毒都表现良好,两者的滴度都降低了4 log10,使Virkon®S成为脊髓灰质炎病毒的合适消毒剂。

We introduce a model for analyzing periodic short-term COVID-19 lockdowns featuring short, alternating periods of W working days and L lockdown days with a weekly cycle: W+L=7. A modified adaptive SIR epidemic model with vaccination (A-SIRV) with a smooth damping function is used to account for periodic suppression of the transmission rate. We use real-world COVID-19 data from Indonesia, United States, Singapore, and Israel to estimate the non-constant transmission and recovery rates using the Method of Variational Imbedding (MVI). The calculated rates reveal that the results of the simulation using A-SIRV models without a damping function approximate the real-world data accurately enough, with low RMSE and MAE values and high values for the coefficient of determination. We also validate the transmission rates with phases of Delta and Omicron variants and obtain agreeable results. We then simulate various scenarios of periodic short-term lockdown using the damped A-SIRV model, finding that implementing five working days and two lockdown days throughout the entire simulation period is sufficient for consistently flattening the number of active cases in the models for Indonesia and United States. However, for the Singapore and Israel models, the use of five working days and two lockdown days only flattens the number of active cases for several years before a blow-up, an extremely high peak of active cases, appears despite the periodic lockdown remaining in place. We then perform additional numerical simulations for Singapore and Israel models and find that the sudden extreme peak can be suppressed by three scenarios: increasing the share of vaccination to the susceptibles, reducing the number of working days per week to three, or using a dynamic policy of five working days per week followed by a policy shift to only two working days per week when sudden extreme peaks start to form. Our study finds that preventive vaccination should be emphasized while allowing partial economic activity during periodic lockdowns.
我们引入了一个以周为周期,W个工作日和L个工作日交替进行的周期性短期封锁分析模型:W+L=7。采用带有平滑阻尼函数的改进自适应SIR流行病模型(A- sirv)来解释传播率的周期性抑制。我们使用来自印度尼西亚、美国、新加坡和以色列的真实COVID-19数据,使用变分嵌入法(MVI)估计非恒定传播和恢复率。计算速率表明,不加阻尼函数的a - sirv模型的模拟结果与实际数据足够接近,RMSE和MAE值较低,决定系数值较高。我们还用Delta和Omicron变体的相位验证了传输速率,得到了令人满意的结果。然后,我们使用阻尼的A-SIRV模型模拟了周期性短期封锁的各种情景,发现在整个模拟期间实施五个工作日和两个封锁日足以使印度尼西亚和美国模型中的活跃病例数量持续趋于平稳。然而,对于新加坡和以色列的模式,使用5个工作日和2个封锁日只会使活跃病例数在几年内趋于平缓,然后出现爆发,即活跃病例的极高峰值,尽管定期封锁仍然存在。然后,我们对新加坡和以色列的模型进行了额外的数值模拟,发现突然的极端峰值可以通过三种情况来抑制:增加易感人群的疫苗接种份额,将每周工作日减少到三天,或者使用每周五个工作日的动态政策,然后在突然的极端峰值开始形成时将政策转变为每周只有两个工作日。我们的研究发现,应强调预防性疫苗接种,同时在周期性封锁期间允许部分经济活动。

The scope of this work focuses on the digital assets of citizens and their personal and private inheritance. The aim is to protect such digital assets after your death, for example, personal email accounts, not those within the corporate domain, which are neither inheritable nor owned by the employee. It is based on blockchain technology due to the intrinsic need to govern hereditary information. These needs include a public and secure record of transactions that cannot be altered, confidence in the integrity of stored data, decentralization of information, the immutability of records, efficiency, and speed. These features empower users with greater control over their data and transactions. Users, as beneficiaries of their digital assets, will be able to establish specific, planned, and transparent conditions for their digital assets after death safely and transparently, ensuring that the records of these transactions are secure and auditable. By adopting these solutions and planning their digital estate in advance, users can ensure that it is managed securely and effectively for future generations.

An empirical study on deployment in cross-chain decentralised autonomous organisations 跨链分散自治组织部署的实证研究

Decentralised Autonomous Organisations (DAOs) are self-governing democratic entities that operate and provide services via smart contracts on behalf of their users. Certain DAOs, particularly Decentralised Exchanges (DEXs), have recently expanded their market reach through cross-chain deployment and integration, giving rise to Cross-chain DAOs (XDAOs). These XDAOs face unique governance, deployment, and operations challenges, introducing added complexity and risks compared to traditional single-chain DAOs. While existing research has focused primarily on single-chain DAOs, we observe a shift in practice with DAOs to favour cross-chain deployments. The three largest protocols, Uniswap, Curve, and PancakeSwap, which together represent over half of the total value locked in DEXs, have been deployed across 22, 17, and 9 chains, respectively. This creates a research gap that our study addresses. In this study, we review 48 cross-chain deployments and numerous XDAO interactions, using data primarily from their respective discussion forums. Through thematic and root cause analysis, we identify eight requirements, deviations between DEXs, seven lessons learned for cross-chain deployment, and a framework to generalise the governance and deployment processes in XDAOs. As a result, we provide an improved classification of XDAO governance, highlighting limitations and future directions for cross-chain expansion.
去中心化自治组织(dao)是自治的民主实体,代表其用户通过智能合约运营和提供服务。某些dao,特别是去中心化交易所(DEXs),最近通过跨链部署和集成扩大了其市场范围,从而产生了跨链dao (xdao)。这些xdao面临着独特的治理、部署和操作挑战,与传统的单链dao相比,引入了额外的复杂性和风险。虽然现有的研究主要集中在单链dao上,但我们观察到dao在实践中的转变有利于跨链部署。三大协议Uniswap、Curve和PancakeSwap,分别部署在22条、17条和9条链上,占DEXs锁定总价值的一半以上。这就造成了我们的研究要解决的研究空白。在本研究中,我们回顾了48个跨链部署和大量XDAO交互,主要使用了来自各自论坛的数据。通过主题和根本原因分析,我们确定了八个需求、DEXs之间的偏差、跨链部署的七个经验教训,以及一个概括xdao中治理和部署流程的框架。因此,我们提供了一种改进的XDAO治理分类,强调了跨链扩展的局限性和未来方向。

This creates a research gap that our study addresses. In this study, we review 48 cross-chain deployments and numerous XDAO interactions, using data primarily from their respective discussion forums. Through thematic and root cause analysis, we identify eight requirements, deviations between DEXs, seven lessons learned for cross-chain deployment, and a framework to generalise the governance and deployment processes in XDAOs. As a result, we provide an improved classification of XDAO governance, highlighting limitations and future directions for cross-chain expansion.</div></div>","PeriodicalId":53141,"journal":{"name":"Blockchain-Research and Applications","volume":"6 3","pages":"Article 100291"},"PeriodicalIF":5.6,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145104884","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
