Many European Universities emerged since the first call in 2019, up to now 44 of them. These alliances have some specific goals but also share basic ideas like boosting student, teacher and researcher mobility and cooperation or creating and implementing joint study programmes. To fulfil these shared goals and keep the related processes running smoothly in the alliance, a virtual campus is often envisioned as an information system that will bind the partner universities’ information and fill in the gaps where needed. However, building such a system presents a number of challenges on organisational, informational, and technical levels.In this paper, the basic functionalities of virtual campuses are identified, and a set of specific principles for building such a distributed information system is stated. The architecture of such a system is presented using the example of a particular virtual campus, along with the lessons learned in creating it. The topic is complemented with information on the current state of the system and the future work on this virtual campus.
自2019年第一次呼吁以来,涌现了许多欧洲大学,目前已有44所大学。这些联盟有一些具体的目标,但也有一些共同的基本理念,比如促进学生、教师和研究人员的流动性和合作,或者创建和实施联合研究项目。为了实现这些共同的目标,并保持联盟中相关流程的顺利运行,虚拟校园通常被设想为一个信息系统,它将绑定合作大学的信息,并在需要时填补空白。然而,构建这样一个系统在组织、信息和技术层面上提出了许多挑战。本文明确了虚拟校园的基本功能,并阐述了构建分布式信息系统的一套具体原则。本文以一个特定的虚拟校园为例,介绍了这种系统的体系结构,以及在创建过程中获得的经验教训。该主题还补充了该系统的现状和该虚拟校园未来工作的信息。

This research paper proposes a digitalization framework based on Society 5.0 principles for promoting resilient and sustainable agricultural value chains in the context of climate change. Climate change is affecting the productivity and sustainability of agricultural systems and threatening food security in many parts of the world. Digitalization has the potential to enhance the resilience of agricultural value chains to climate change by improving efficiency, promoting sustainability, and reducing vulnerability to climate risks. This study reviews the literature to investigate the potential benefits and challenges of Society 5.0-inspired digitalization for agricultural value chains in the context of resilience and sustainability. Further, this study establishes critical design requirements for digitalization, which inform the development of a theoretical framework for Society 5.0-inspired digitalization framework in realizing resilient and sustainable agricultural value chains.
本研究提出了一个基于社会5.0原则的数字化框架,以促进气候变化背景下有弹性和可持续的农业价值链。气候变化正在影响农业系统的生产力和可持续性,并威胁到世界许多地区的粮食安全。数字化有可能通过提高效率、促进可持续性和减少对气候风险的脆弱性来增强农业价值链对气候变化的抵御能力。本研究回顾了文献,探讨了在韧性和可持续性背景下,社会5.0启发的数字化对农业价值链的潜在好处和挑战。此外,本研究建立了数字化的关键设计要求,为社会5.0启发的数字化框架的理论框架的发展提供了信息,以实现弹性和可持续的农业价值链。

Since the joint EUNIS/euroCRIS CRIS/IR survey report was published in 2016, Current Research Information Systems (CRISs) have become even more widely implemented at institutions and in countries all over the world. These platforms traditionally serve a double purpose: as tools to showcase the research activity conducted within its walls and as internal databases to enable evidence-based decision-making processes. Increasingly, they also act as a reliable and comprehensive information source for external systems and services. This text provides a snapshot of the current CRIS landscape – with an emphasis on Europe – and summarises the various ways CRISs are currently used as well as introduces new emerging uses and scenarios. Special attention is paid to the ever-growing number of national and regional CRIS platforms, which are increasingly seen as valuable research information collection systems for the analysis of the strengths and weaknesses of research in specific geographies.
自2016年EUNIS/euroCRIS联合发布CRIS/IR调查报告以来,当前研究信息系统(CRISs)在世界各地的机构和国家中得到了更广泛的应用。这些平台传统上具有双重目的:作为展示其内部进行的研究活动的工具,以及作为实现基于证据的决策过程的内部数据库。它们也逐渐成为外部系统和服务的可靠和全面的信息源。本文提供了当前CRIS景观的快照-重点是欧洲-并总结了目前使用CRIS的各种方式,并介绍了新的新兴用途和场景。特别注意数目日益增加的国家和区域危机信息系统平台,这些平台日益被视为有价值的研究资料收集系统,可用于分析特定地区研究的优缺点。

Clarifying the biological nature of the interaction between the systems-based epigenetic landscape and the epigenome 阐明基于系统的表观遗传景观与表观基因组相互作用的生物学本质

The epigenetic landscape concept initially proposed by Conrad H. Waddington has become a powerful tool to quantitatively address constraints underlying cell differentiation and morphogenesis. In theoretical and experimental terms, this has been enabled by grounding gene regulatory network models on experimental data. Such models have, in turn, led to proposing epigenetic landscape models that entail functional and structural constraints of cell differentiation and morphogenetic dynamics, and thus the understanding of development from a systems–based perspective. Therefore, it is mainly in the context of the study of development where the epigenetic landscape has been anchored as a conceptual support. On the other hand, nonetheless, given the recent understanding of gene control by epigenomic modifications and the capacity to profile these modifications using high– throughput molecular techniques, the notion of epigenetics has been mainly related to non-genetic heritable modifications of the genome. Therefore, this approach, which until now has not been based on a systems–based dynamical treatment, has given proximal epigenomic modifications a central role in understanding development. The latter, has left the dynamic view of epigenetic landscape aside. In this paper we aim at establishing a conceptual link between both conceptualizations of epigenetic regulation.
最初由Conrad H. Waddington提出的表观遗传景观概念已经成为定量解决细胞分化和形态发生限制的有力工具。在理论和实验方面,这是通过在实验数据上建立基因调控网络模型来实现的。这样的模型反过来又导致了表观遗传景观模型的提出,这些模型需要细胞分化和形态发生动力学的功能和结构约束,从而从基于系统的角度理解发育。因此,它主要是在发展研究的背景下,表观遗传景观已被锚定为概念支持。另一方面,尽管如此,鉴于最近对表观基因组修饰的基因控制的理解以及使用高通量分子技术描述这些修饰的能力,表观遗传学的概念主要与基因组的非遗传遗传修饰有关。因此,这种迄今为止尚未基于系统动力学治疗的方法,已经赋予近端表观基因组修饰在理解发育方面的核心作用。后者把表观遗传景观的动态观点放在一边。在本文中,我们的目的是建立两个概念之间的概念联系表观遗传调控。

Bert Zulauf, Nina Knipprath
At German universities and universities of applied sciences, a new way of working is currently opening up in the area of the structure and composition of laboratory work: Documentation by means of electronic laboratory notebooks (ELN). Researchers produce and use a colourful mixture of data such as graphic files, formulas, tables or microscopy files. At Heinrich Heine University Düsseldorf (HHU), advice and support for researchers in the field of research data management (RDM) is provided on a regular basis. In addition to assistance with applications, we also offer support using various RDM tools, including electronic lab books. Why it makes sense to use electronic lab books, how our path with them has progressed so far, and what are the current hurdles to be overcome are presented in this report.

The Role of Universities in the Implementation of Persistent Identifiers (PIDs) 大学在实现持久标识符(pid)中的作用
Pub Date : 2023-01-01 DOI: 10.29007/97w6
P. de Castro, Ulrich Herb, Laura Rothfritz, Joachim Schöpfel
The report “Building the plane as we fly it: the promise of persistent identifiers” was published last February by the Knowledge Exchange. The report explores the challenges, opportunities, risks and trust-related issues associated with the quickly-developing PID landscape with an emphasis on the six KE member countries (Denmark, Finland, France, Germany, Netherlands and the United Kingdom). A series of seven complementary case studies were published alongside this report examining more in depth the current PID landscape for specific entities such as authors, organisations, instruments and facilities, grants and projects or physical samples. The report summarises the findings of a series of interviews with PID experts that provided the basis for the study. Sets of recommendations are also provided for a range of relevant stakeholders in the PID implementation domain. The current fragmentation of the PID landscape is one of the main challenges highlighted in the report and the case studies. This contribution provides a summary of the findings of this study and analyses this fragmented PID landscape in some detail, specifically exploring the meaning of “community” in expressions like “a community-driven PID landscape”. The role universities are expected to play in the gradual, unstoppable adoption of a wide range of PIDs is laid out, together with some early best practices in the domain.
去年2月,知识交流(Knowledge Exchange)发布了一份名为《边飞边造飞机:持久标识符的前景》的报告。该报告探讨了与快速发展的PID环境相关的挑战、机遇、风险和与信任相关的问题,重点是六个KE成员国(丹麦、芬兰、法国、德国、荷兰和英国)。本报告同时发布了一系列七个补充案例研究,更深入地研究了当前特定实体(如作者、组织、仪器和设施、赠款和项目或物理样本)的PID景观。该报告总结了与PID专家进行的一系列访谈的结果,这些访谈为这项研究提供了基础。还为PID实现领域的一系列相关利益相关者提供了一系列建议。目前PID格局的碎片化是报告和案例研究中强调的主要挑战之一。这篇文章总结了本研究的发现,并对这种碎片化的PID景观进行了一些详细的分析,特别是探讨了“社区驱动的PID景观”等表达中“社区”的含义。在逐步、不可阻挡地广泛采用pid的过程中,预计大学将发挥的作用,以及该领域的一些早期最佳实践。

On social media, false information can proliferate quickly and cause big issues. To minimize the harm caused by false information, it is essential to comprehend its sensitive nature and content. To achieve this, it is necessary to first identify the characteristics of information. To identify false information on the internet, we suggest an ensemble model based on transformers in this paper. First, various text classification tasks were carried out to understand the content of false and true news on Covid-19. The proposed hybrid ensemble learning model used the results. The results of our analysis were encouraging, demonstrating that the suggested system can identify false information on social media. All the classification tasks were validated and shows outstanding results. The final model showed excellent accuracy (0.99) and F1 score (0.99). The Receiver Operating Character- istics (ROC) curve showed that the true-positive rate of the data in this model was close to one, and the AUC (Area Under The Curve) score was also very high at 0.99. Thus, it was shown that the suggested model was effective at identifying false information online.
在社交媒体上,虚假信息可以迅速扩散并引发大问题。为了最大限度地减少虚假信息造成的危害,有必要了解其敏感性和内容。要做到这一点,有必要首先确定信息的特征。为了识别互联网上的虚假信息,本文提出了一种基于变压器的集成模型。首先,进行各种文本分类任务,了解Covid-19假新闻和真实新闻的内容。提出的混合集成学习模型利用了这些结果。我们的分析结果令人鼓舞,表明建议的系统可以识别社交媒体上的虚假信息。对所有分类任务进行了验证,并取得了显著的效果。最终模型的准确率为0.99,F1分数为0.99。受试者工作特征(ROC)曲线显示,该模型中数据的真阳性率接近于1,曲线下面积(AUC)得分也非常高,为0.99。因此,该模型在识别在线虚假信息方面是有效的。

Uncovering the role of mutations in Epithelial-to-Mesenchymal transition through computational analysis of the underlying gene regulatory network 通过对潜在基因调控网络的计算分析,揭示突变在上皮细胞向间质细胞转化中的作用

We illustrate here a systems-based computational analysis technique intended for uncov- ering dynamic properties of gene regulatory networks described in discrete Boolean terms. This through the use of the algebraic Semi-Tensor Product (STP), and with the purpose of exploring the regulatory consequences of genetic mutations in the modification of cell phenotypes. The proposed technique derives from the state-based reachability analysis of dynamic systems via the design of open-loop perturbative control schemes. We choose as a case-of-study the discrete Boolean network that describes in qualitative formal terms the transcriptional gene regulatory network that underlies the Epithelial-to-Mesenchymal transition in the context of epithelial cancer. We are particularly interested in qualitatively understanding the systems level consequences of mutations in specific genes that regulate the phenotypic transition. More specifically, we are interested in bringing to light potential preventive therapeutic interventions that promote the Mesenchymal-to-Epithelial transition.
我们在这里说明了一种基于系统的计算分析技术,旨在揭示以离散布尔术语描述的基因调控网络的动态特性。这是通过使用代数半张量积(STP),并以探索基因突变在细胞表型修饰的调控后果的目的。通过设计开环摄动控制方案,对动态系统进行基于状态的可达性分析。我们选择离散布尔网络作为研究案例,该网络以定性形式描述了上皮癌背景下上皮到间质转化的转录基因调控网络。我们对定性地理解调节表型转变的特定基因突变的系统水平后果特别感兴趣。更具体地说,我们感兴趣的是揭示潜在的预防治疗干预,促进间质向上皮的转变。

The Velvet Assembler Using OpenACC Directives 使用OpenACC指令的天鹅绒汇编器
Pub Date : 2023-01-01 DOI: 10.29007/pzbt
E. B. Costa, Gabriel P. Silva
There are several programs available in bioinformatics for DNA sequence assembly. This is typically an extremely time-consuming endeavor, as DNA sequences can be extensive and intricate. Velvet was created to combine short and long read sequencing data into larger genomic sequences. Using OpenMP parallel programming, the last version of Velvet was created to support multiple threads. Through OpenACC directives, we present a new version of Velvet that takes advantage of multiprocessing using graphical processing units (GPU). Our tests demonstrate that this extension of Velvet allows for faster performance and efficient memory use.

Our tests demonstrate that this extension of Velvet allows for faster performance and efficient memory use.","PeriodicalId":93549,"journal":{"name":"EPiC series in computing","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69449928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Those advocating for technology integration within education claim that teachers need to reform their pedagogic practices to make learning more engaging and relevant. While educational technology researchers claim teachers are primarily responsible for these failures, it seems teachers do not embrace technology unquestionably. This paper aims to develop an understanding of how teachers’ beliefs and professional dispositions (PDs) influence technology use within different social and educational contexts. A set of three interviews were conducted at four South African secondary schools with vastly different social contexts, over different periods of time (before and during COVID) with cross-case analyses. Findings show that the provision of technology does not guarantee integration as use varies amongst teachers within technology-rich schools, with teachers who hold more positive Internal Beliefs (IBs) of technology not only focusing less on External Structure (ES) barriers, but also utilising technology in more varied ways, even to enhance and transform their pedagogic practices. Furthermore, teachers’ PDs seem to exist on a continuum and do not appear to be the sole influencer of technology use, with the context alongside the school’s technology policy and related technology structures influencing teachers’ IBs and resulting technology use. In addition, while mandatory use of technology during COVID led to more positive IBs as teachers understood the value of the technology, this only appears to be true if external structures (ESs) supported the learners as well. Moreover, all teachers expressed their belief that technology is no replacement for face-to-face teaching. Finally, the rich data from the interviews underlined the intricacies of factors influencing the use of technology in classrooms, indicating a need for a meta-theory to gain a holistic understanding of technology use by teachers.
那些倡导在教育中整合技术的人声称,教师需要改革他们的教学实践,使学习更具吸引力和相关性。虽然教育技术研究人员声称教师对这些失败负有主要责任,但教师似乎并没有毫无疑问地接受技术。本文旨在了解教师的信仰和专业倾向(pd)如何影响不同社会和教育背景下的技术使用。在不同时期(COVID之前和期间),在社会背景截然不同的四所南非中学进行了三次访谈,并进行了跨案例分析。研究结果表明,技术的提供并不能保证整合,因为在技术丰富的学校里,教师的使用情况各不相同,对技术持有更积极的内在信念(ib)的教师不仅较少关注外部结构(ES)障碍,而且还以更多样化的方式利用技术,甚至可以增强和改变他们的教学实践。此外,教师的个人发展倾向似乎存在于一个连续体中,似乎并不是技术使用的唯一影响因素,学校的技术政策和相关的技术结构都影响着教师的个人发展倾向和由此产生的技术使用。此外,虽然在COVID期间强制使用技术导致了更积极的ib,因为教师了解技术的价值,但这似乎只有在外部结构(ESs)也支持学习者的情况下才能实现。此外,所有教师都表示,他们认为技术不能取代面对面的教学。最后,来自访谈的丰富数据强调了影响课堂技术使用的因素的复杂性,表明需要一种元理论来全面了解教师的技术使用情况。
