摘要： This paper describes a collaborative project that was conducted to promote the Computer Science (CS) and Computation Thinking (CT) Education among Education Faculties. 9 Education Faculties from three local and regional schools participated in a learning experience designed to address the K-12 Computer Science Framework[1] and Maryland's K-12 Computer Science Standards. The collaboration was designed to develop CS/CT knowledge, understanding, skills and application among Education Faculties who work to prepare teachers. The plan is to build the capacity of faculty to integrate CS and CT into several preservice courses as well as build into the coursework sequence meaningful experiences that expose future teachers to CS and CT knowledge and skills so that they can in turn incorporate these into their own lesson plans. Project evaluation included formative and summative assessments to examine changes in content and pedagogical knowledge. Phase one feedback from the participants shows positive result.

摘要： Some specific services for Internet of Things, such as real-time map and providing local weather information, depend strongly on geographical time and location. We refer to the data for such service as spatio-temporal data (STD). When STD is used in a query response system similar to conventional Internet services, users not only need to acquire data actively as required, they must also have functions for retrieving data available STD. Therefore, we propose an STD retention system that uses vehicles as information hubs (InfoHubs) for disseminating and retaining the data in a specific area. In our system, InfoHubs diffuse, maintain, and advertise STD over places and times where the STD are strongly dependent, thereby allowing users to receive such data passively within the specific area. Additionally, because STD are associated with a particular space, the system can reduce search costs. We also propose an adaptive transmission control method that each vehicle effectively operates its wireless resources autonomously and STD are retained and distributed efficiently. Finally, we evaluated our proposed method using simulations and clarified that our proposed system is capable of achieving a coverage rate of nearly 100 percent for STD while reducing the number of data transmissions compared to existing systems.

摘要： The article deals with the problem of creating conditions for the formation of metasubject educational results of primary schoolchildren, including communicative and regulatory universal educational actions, in the context of the digitalization of education. The analysis of scientific literature has shown that after the transition of the initial stage of education to the second generation standard in 2010, this problem still occurs. The article describes the possibilities of implementing joint network activities of elementary school students within the framework of the academic subject “informatics” in a specially organized digital educational environment that promotes the formation of universal educational actions by gradually increasing the complexity of network communication through the joint performance of network tasks based on a four-level model of network interaction. Positive influence of the inclusion of network interaction in lesson activities in elementary school on students’ readiness to carry out training in a remote mode has been substantiated.

摘要： The breakdown of vital communication infrastructures is one of the most common characteristics of all disasters. It can cause severe communication problems such as time delays and data loss, which cause deterioration in system performance. New techniques are needed to cope with such situations, many of which have been made possible due to the ongoing evolution of artificial intelligence technologies. In this study, we consider the case of a network consisting of several router allocation problems in situations of high priority and emergency data allocation. A novel network component called the scheduler is introduced and window constraints for routers are imposed. To solve the studied problem, four different algorithms are developed in this work. These algorithms were then applied in a particular scenario consisting of several routers and 2200 instances. In terms of the gap and running time, the proposed algorithms provide acceptable results. The best performances were achieved using the critical packet algorithm for 80% of instances with an average gap value of 0.009 and an average time of 0.209 s.

摘要： As software has become more essential to research across disciplines, and as the recognition of this fact has grown, so too has the importance of professionalizing the development and maintenance of this software. The community of software professionals who work on this software have come together under the title "research software engineer" ("RSE") over the last decade. This, in turn, has created the need to understand how RSEs come into this profession and into these groups, how to further promote this career path to potential members as well as the need to understand what training gaps need to be filled for RSEs coming from different entry points. We have categorized three main classifications of entry paths into the RSE profession and identified key elements, both advantages and disadvantages, that should be acknowledged and addressed by the broader research community to attract and retain a talented, diverse pool of future RSEs.

摘要： When a user is performing a manual task, AR or VR can provide information about the current subtask (cueing) and upcoming subtasks (precueing) that makes them easier and faster to complete. Previous research on cueing and precueing in AR and VR has focused on path-following tasks requiring simple actions at each of a series of locations, such as pushing a button or just visiting. We consider a more complex task, whose subtasks involve moving to and picking up an item, moving that item to a designated place while rotating it to a specific angle, and depositing it. We conducted two user studies to examine how people accomplish this task while wearing an AR headset, guided by different visualizations that cue and precue movement and rotation. Participants performed best when given movement information for two successive subtasks and rotation information for a single subtask. In addition, participants performed best when the rotation visualization was split across the manipulated object and its destination.

摘要： MicroRNA (miRNA) is a class of non-coding single-stranded RNA molecules encoded by endogenous genes with a length of about 22 nucleotides. MiRNAs have been successfully identified as differentially expressed in various cancers. There is evidence that disorders of miRNAs are associated with a variety of complex diseases. Therefore, inferring potential miRNA-disease associations (MDAs) is very important for understanding the aetiology and pathogenesis of many diseases and is useful to disease diagnosis, prognosis and treatment. First, We creatively fused multiple similarity subnetworks from multi-sources for miRNAs, genes and diseases by multiplexing technology, respectively. Then, three multiplexed biological subnetworks are connected through the extended binary association to form a tripartite complete heterogeneous multiplexed network (Tri-HM). Finally, because the constructed Tri-HM network can retain subnetworks' original topology and biological functions and expands the binary association and dependence between the three biological entities, rich neighbourhood information is obtained iteratively from neighbours by a non-equilibrium random walk. Through cross-validation, our tri-HM-RWR model obtained an AUC value of 0.8657, and an AUPR value of 0.2139 in the global 5-fold cross-validation, which shows that our model can more fully speculate disease-related miRNAs.
