IvTerm-An R package for interactive visualization of functional analysis results of meta-omics data.

Interpreting functional analysis results derived from environmental samples using direct sequencing meta-omics data, including metagenomics and meta-transcriptomics data, is challenging due to their complexity. Visualization of functional analysis results can help researchers discover relevant biological insights. Despite the availability of many R packages, there lacks interactive and comprehensive graphic systems for displaying functional terms and corresponding genes in meta-omics analysis results.Here, we present ivTerm, an R-shiny package with a user-friendly graphical interface that enables users to inspect functional annotations, compare results across multiple experiments, create customized charts, and download these charts. It provides various basic and innovative chart types to visualize functional terms and involved genes. Users can also browse the description of terms obtained from the database web servers automatically. Two examples, including a metagenome analysis data for human gut and a meta-transcriptome data for coral symbiomes, are given to show the usage of ivTerm. In the end, we compared ivTerm with existing tools with similar functions, such as GOplot, ViSEAGO, and Chordomics.The tool ivTerm is convenient and efficient for biologists to gain an integrated view and develop deep insights by interactive analysis of meta-omics data. It can accelerate the procedure to develop insights from complex meta-omics data. The code for ivTerm is freely available at https://github.com/SJTU-CGM/ivTerm.

Computing Algorithm of Robot Distributed 3D Graphic Simulation System

In view of the shortcomings of current multi-robot path planning strategies, such as high path coupling, long total path, and long waiting time for collision avoidance, as well as the resulting problems of low system robustness and low robot utilization, the paper proposes Multi-robot path planning particle swarm algorithm based on distributed three-dimensional space-time graphics and motion decomposition. We first generate a dynamic temporary obstacle in the time dimension according to the existing path set and the current robot position, and expand it together with the static obstacle into a three-dimensional search graphics space. Secondly, in the three-dimensional image space, the total path movement time is divided into three parameters: movement time, turning time and staying time in place, and using the conditional depth-first search strategy to calculate all the matching parameters from the starting node to the target node the required path collection. The experimental results show that the path of distributed 3D graphics planning by our proposed particle swarm algorithm has the advantages of total length, less running time, system collision-free, and high robustness, which solves the problem of multi-robot systems completing continuous random tasks.

Modelling local nanobiomaterial release and concentration hotspots in the environment

Nanobiomaterials (NBMs) are a special category of nanomaterials used in medicine. As applications of NBMs are very similar to pharmaceuticals, their environmental release patterns are likely similar as well. Different pharmaceuticals were detected in surface waters all over the world. Consequently, there exists a need to identify possible NBM exposure routes into the environment. As the application of many NBMs is only carried out at specific locations (hospitals), average predicted environmental concentrations (PECs) may not accurately represent their release to the environment. We estimated the local release of poly(lactic-co-glycolic acid) (PLGA), which is investigated for their use in drug delivery, to Swiss surface waters by using population data as well as type, size and location of hospitals as proxies. The total mean consumption of PGLA in Switzerland using an explorative full-market penetration scenario was calculated to be 770 kg/year. 105 hospitals were considered, which were connected to wastewater treatment plants and the receiving water body using graphic information system (GIS) modelling. The water body dataset contained 20,167 river segments and 210 lake polygons. Using the discharge of the river, we were able to calculate the PECs in different river segments. While we calculated high PLGA releases of 2.24 and 2.03 kg/year in large cities such as Geneva or Zurich, the resulting local PECs of 220 and 660 pg/l, respectively, were low due to the high river discharge (330 and 97 m3/s). High PLGA concentrations (up to 7,900 pg/l) on the other hand were calculated around smaller cities with local hospitals but also smaller receiving rivers (between 0.7 and 1.9 m3/s). Therefore, we conclude that population density does not accurately predict local concentration hotspots of NBMs, such as PLGA, that are administered in a hospital context. In addition, even at the locations with the highest predicted PLGA concentrations, the expected risk is low.

Digital soil morphometrics of coarse fragments and horizon delineation in soil profiles from Central Mexico

In this study, we developed a method that allows the delimitation of horizons and the quantification of coarse fragments in soil profiles from volcanic areas using digital images. The delineation of the soil profile horizons included the following phases: pre-processing of the digital image, extraction of color systems from the pre-processed image, k-means segmentation of the HSV and CIE L*a*b* color systems, delineation of the horizons, and determination of the horizon characteristics. The coarse fragments were quantified in the following three phases: superpixel analysis of the soil profile image, histogram classification of the image objects, and extraction and quantification of the coarse fragments. For horizon delineation, the HSV color system performed better for the Eutric Andic Cambisol (Loamic, Ochric), and the CIE L*a*b* system performed better for the Eutric Skeletic Mollic Silandic Andosol (Loamic). The RGB image and the S component of the HSV system demonstrated similar coarse fragment volume calculation performance for the Eutric Andic Cambisol (Loamic, Ochric), whereas the S component worked best for the Eutric Skeletic Mollic Silandic Andosol (Loamic). We created a graphic decision-making system for the delineation of soil horizons and for the quantification of coarse fragments in digital images of soil profiles.

Simulation-Based Estimation of the Number of Cameras Required for 3D Reconstruction in a Narrow-Baseline Multi-Camera Setup.

Graphical visualization systems are a common clinical tool for displaying digital images and three-dimensional volumetric data. These systems provide a broad spectrum of information to support physicians in their clinical routine. For example, the field of radiology enjoys unrestricted options for interaction with the data, since information is pre-recorded and available entirely in digital form. However, some fields, such as microsurgery, do not benefit from this yet. Microscopes, endoscopes, and laparoscopes show the surgical site as it is. To allow free data manipulation and information fusion, 3D digitization of surgical sites is required. We aimed to find the number of cameras needed to add this functionality to surgical microscopes. For this, we performed in silico simulations of the 3D reconstruction of representative models of microsurgical sites with different numbers of cameras in narrow-baseline setups. Our results show that eight independent camera views are preferable, while at least four are necessary for a digital surgical site. In most cases, eight cameras allow the reconstruction of over 99% of the visible part. With four cameras, still over 95% can be achieved. This answers one of the key questions for the development of a prototype microscope. In future, such a system can provide functionality which is unattainable today.

Energy Harvesting and Water Saving in Arid Regions via Solar PV Accommodation in Irrigation Canals

The Egyptian irrigation system depends mainly on canals that take water from the River Nile; nevertheless, the arid climate that dominates most of the country influences the high rate of water losses, mainly through evaporation. Thus, the main objective of this study is to develop a practical approach that helps to accommodate solar photovoltaic (PV) panels over irrigation canals to reduce the water evaporation rate. Meanwhile, a solar PV panel can contribute effectively and economically to an on-grid system by generating a considerable amount of electricity. A hybrid system includes a solar PV panel and a diesel generator. Several factors such as the levelized cost of energy (LCOE), total net present cost, loss of power supply probability, and greenhouse gas emissions should be considered while developing a technoeconomically feasible grid-connected renewable integrated system. A mathematical formulation for the water loss was introduced and the evaporation loss was monthly estimated. Thus, this study also aims to enhance an innovative metaheuristic algorithm based on a cuckoo search optimizer to show the way forward for developing a technoeconomic study of an irrigation system integrated with an on-grid solar PV panel designed for a 20-year lifespan. The results are compared using the mature genetic algorithm and particle swarm optimization to delimit the optimal size and configuration of the on-grid system. The optimal technoeconomic feasibility is connected to the graphical information system to delimit the optimal length and direction of the solar PV accommodation covering the canals. Finally, based on the simulated results, the optimal sizing and configuration of the irrigation-system-integrated on-grid solar PV accommodation have less impact on the LCOE without violating any constraint and, at the same time, generating clean energy.

African Linguistic Images for Cross-Cultural Communication

Cross-cultural communication takes place when message is transmitted from a person from one culture to another person from a different culture; however, communication scholars estimate that two-thirds of communications are influenced by the culture of the communication. Based on this, this paper explored socio-cultural relationships as they influence the management of communication patterns Africa. With special focus on African linguistic images, the paper analyzed the relationships between African linguistic images and the communicative powers of language, graphic systems, and the written word. Language is a means which human beings have devised for communicating ideas, feelings, emotions, desires, etc, through complex vocal or written symbols; hence, images play a central role in the complex communications that both link and separate communities and institutions.

GrAALF: Supporting graphical analysis of audit logs for forensics

Abstract System-level logs play a critical role in computer forensics. They capture interactions between programs and users in detail. However, a typical computer generates more than 2.5 million system events hourly, making finding malicious activities in such logs compute and time-intensive. We introduce GrAALF a graphical system for efficiently loading, storing, processing, querying, and displaying system events for computer forensics. In comparison to similar systems, GrAALF offers the flexibility of storage, intuitive querying, and the tracing power for longer sequences of events in real-time to help identify attacks. GrAALF is a robust solution for analysis to support computer forensics.

On the specific graphic, orthographic and morphological features of the usus of the monastic scriptoria of Nuremberg in the 15th century

The article examines the graphic, spelling and morphological features characteristic for medieval texts created in Nuremberg. The study involves spiritual literature created in various Nuremberg scriptoria. Each investigated text is considered as an integral and independent graphic and spelling system, consisting of interrelated elements. Following features presented in the studied manuscripts are revealed in the course of the analysis of the texts: the Middle and Early New High German features, features characteristic of the Southeastern, East Frankish and Nuremberg dialects, as well as the spelling features. The reasons for the differences between the graphic and spelling systems of the studied texts from the phonetic system of Early New High German and intertextual differences are subject to interpretation. The analysis of the scriptoria peculiarities makes it possible to determine the place of graphic and orthographic systems in the context of Early New High German linguistic dynamics, as well as the degree of influence of various dialects on them. When considering the graphic and orthographic features of the studied texts, the specificity of the written fixation of Early New High German is taken into account as well as the fact that the urban written language and the urban dialect are different sources of influence on the formation of the written tradition of each scriptorium. This study allows to conclude about the degree of independence of the graphic and spelling systems of manuscripts and about the usability of the norms of the written language of the period under study.

Modeling in AUTOCAD for bachelors

The article discusses the methods of using the AutoCad graphic editor for creating three-dimensional objects. The possibilities of three-dimensional modeling in the AutoCad graphic editor for optimizing the educational process of bachelors of technical specialties are also considered. The article analyzes the best ways to create mechanical engineering drawings.The most developed software tool for the production of design documentation is AutoCAD - a universal graphic design system. Creating models of any complexity in space by using this graphic editor, the user will be able to see their relative position, estimate the distance between them. The model can be freely moved in space, viewing many options. The ability to control the point of view allows to conveniently select the view of the 3D model that is being developed. Zooming, panning in real time with the ability to freely rotate the camera around the model provide the ability to quickly view objects from any point of view. The article provides examples of choosing the most optimal option for creating a three-dimensional model. The traditional way to create a 3D model drawing is to make 2D views of the model. When creating a flat drawing, there is a possibility of error when making projections, since they are created independently from each other and consist of several images. It is rather difficult to represent an object in space from a flat drawing. At present, modern software graphic editors are aimed at creating three-dimensional models that allow to create realistic models and, on their basis, get two-dimensional projections. Graphic editor AutoCad allows to create three-dimensional objects based on standard commands, in the form of a cylinder, cone, box, torus, etc., when editing which you can get the desired shapes. After creating a three-dimensional model, the user can get its two-dimensional projections not only on the main planes, but also on any plane at will. The 3D modeling method allows you to create a complex drawing with any number of images based on a 3D model. There are ways to create 2D plane drawings from a 3D model and the ability to edit ready-made designs that can be inserted from model space into paper space. Editing takes place by changing the parameters of a 3D object in model space, and these changes are automatically reflected in paper space. This method allows us to use the tools to quickly create a system of 3-4 linked views for a 3D AutoCad model.

Defining Digital Game-Based Learning for Science, Technology, Engineering, and Mathematics: A New Perspective on Design and Developmental Research.

In the modern age, digital games are widely used as informal media for Science, Technology, Engineering, and Mathematics (STEM) education and medical therapy for game-based learning. Digital games provide learners with a graphical system of interaction that enhances scientific concepts within an enjoyable environment. The vastly increasing number of digital games produced in the market affects the quality of STEM digital games while requiring multidisciplinary expertise. This paper proposes a framework for STEM digital game-based learning encompassing input-process-output stages. Several studies from the early 2000s onward were reviewed to discuss and present a new perspective on a framework for the design and development of digital games, particularly for STEM. This proposed framework consists of digital game development as input, experience as a process, and constructs as output. This simple and precise framework will generate a universal product for various types of learners. It can thus be used as a guideline for game designers, developers, and experts to develop STEM digital games and achieve better learning outcomes.
