Abstract Background With advancements in omics technologies, the range of biological processes where long non-coding RNAs (lncRNAs) are involved, is expanding extensively, thereby generating the need to develop lncRNA annotation resources. Although, there are a plethora of resources for annotating genes, despite the extensive corpus of lncRNA literature, the available resources with lncRNA ontology annotations are rare. Results We present a lncRNA annotation extractor and repository (Lantern), developed using PubMed’s abstract retrieval engine and NCBO’s recommender annotation system. Lantern’s annotations were benchmarked against lncRNAdb’s manually curated free text. Benchmarking analysis suggested that Lantern has a recall of 0.62 against lncRNAdb for 182 lncRNAs and precision of 0.8. Additionally, we also annotated lncRNAs with multiple omics annotations, including predicted cis-regulatory TFs, interactions with RBPs, tissue-specific expression profiles, protein co-expression networks, coding potential, sub-cellular localization, and SNPs for ~ 11,000 lncRNAs in the human genome, providing a one-stop dynamic visualization platform. Conclusions Lantern integrates a novel, accurate semi-automatic ontology annotation engine derived annotations combined with a variety of multi-omics annotations for lncRNAs, to provide a central web resource for dissecting the functional dynamics of long non-coding RNAs and to facilitate future hypothesis-driven experiments. The annotation pipeline and a web resource with current annotations for human lncRNAs are freely available on sysbio.lab.iupui.edu/lantern.

In dynamic and big data environments the visualization of a segmentation process over time often does not enable the user to simultaneously track entire pieces. The key points are sometimes incomparable, and the user is limited to a static visual presentation of a certain point. The proposed visualization concept, called ExpanDrogram, is designed to support dynamic classifiers that run in a big data environment subject to changes in data characteristics. It offers a wide range of features that seek to maximize the customization of a segmentation problem. The main goal of the ExpanDrogram visualization is to improve comprehensiveness by combining both the individual and segment levels, illustrating the dynamics of the segmentation process over time, providing “version control” that enables the user to observe the history of changes, and more. The method is illustrated using different datasets, with which we demonstrate multiple segmentation parameters, as well as multiple display layers, to highlight points such as new trend detection, outlier detection, tracking changes in original segments, and zoom in/out for more/less detail. The datasets vary in size from a small one to one of more than 12 million records.

One of the pinnacles of form in classical Western music, the fugue is often used in the teaching of music analysis and composition. Fugues alternate between instances of a subject and other patterns and modulatory sections, called episodes. Musicological analyses are generally built on these patterns and sections. We have developed several algorithms to perform an automated analysis of a fugue, starting from a score in which all the voices are separated. By focusing on the diatonic similarities between pitch intervals, we detect subjects and countersubjects, as well as partial harmonic sequences inside the episodes. We also implemented tools to detect subject scale degrees, cadences, and pedals, as well as a method for segmenting the fugue into exposition and episodic parts. Our algorithms were tested on a corpus of 36 fugues by J. S. Bach and Dmitri Shostakovich. We provide formalized ground-truth data on this corpus as well as a dynamic visualization of the ground truth and of our computed results. The complete system showed acceptable or good results for about one half of the fugues tested, enabling us to depict their design.

Correction for ‘Dynamic visualization of mRNA splicing variants with a transactivating reporter’ by Si Chen et al., Chem. Commun., 2021, DOI: 10.1039/d1cc02439f.


The present work presents a research carried out with 6th and 7th grade students of Elementary School II at Escola Municipal Mon. Walfredo Gurgel Alto do Rodrigues/RN, aiming to encourage the use of materials such as Ruler and Square in Mathematics classes and to know your opinion about the use of Augmented Reality and Virtual Reality glasses. This aimed at a reflective analysis of how the inclusion of technologies in education can enhance learning when the use of multimedia resources that help in understanding mathematical concepts or that enable a dynamic visualization of the object of study are encouraged. She seeks to know what the contribution of this device to the teaching and learning process of Mathematics. Methodologically, the work is characterized as an exploratory research of qualitative and quantitative nature, with a bias towards a case study, with data collected through a semi-structured questionnaire with 102 students. We can count on an interdisciplinary planning to present the programmed contents with more meaning. The results were analyzed based on the research instruments and the testimonies of the students, in addition to a brief study on information and communication technologies applied to learning. Thus, the data are organized in graphs where the research findings are expressed.

By using object oriented method design graph vertices into class, and in this foundation to increase visual member, realize from the source point to the other vertex of the shortest path algorithm of dynamic visualization. Around the two sync window animation, the left window with thick lines drawn through the vertices and edges, " revealed the source point to the other vertex of the shortest path " list box display shortest path sequence and path length, the right window demonstration algorithm dynamic implementation process, and in the " S " text box to display the current most find shortest path vertices. The system has friendly interface, visual image.
