Since 1999, PhysioNet (http://physionet.org/) has offered free access via the web to large collections of recorded physiologic signals and medical databases as well as associated open-source software. The intention of this scientific resource is to stimulate current research and new investigations in the study of cardiovascular and other complex biomedical signals. PhysioBank archives include today the records obtained from healthy individuals and from patients with different diagnoses obtained under various conditions. It includes sudden cardiac death, congestive heart failure, neurological disorders, epilepsy and many others. Software packages PhysioToolkit is valuable for physiological signal processing and analysis, for creation of new databases, the interactive display and characterization of signals, the simulation of physiological and other signals. Nonetheless, a researcher should have skills to work with the operating system Unix and be knowledgeable in special commands to successful use software PhysioToolkit. Therefore, it makes sense to convert the necessary signals to a user-friendly computer algebra system. This paper describes interface elements of scientific web-resource PhysioNet, the simple methods of converting from binary medical data files to the text format and import of received digital signals into computer mathematics system Maple 17.

Abstract Radian Corporation has developed extensive data display capabilities to analyze vibration and acoustic data from structures and rotating equipment. The Machinery Interactive Display and Analysis System (MIDAS) displays data collected through the acquisition functions of MIDAS. The graphics capabilities include displaying spectra in three-dimensional waterfall and in X-Y formats. Both types of plots can relate vibrations to time, equipment speed, or process parameters. Using menu-driven parameter selection, data can be displayed in formats that are the most useful for analysis. The system runs on a popular mini-computer, and it can be used with a great variety of graphics terminals, workstations, and printer/plotters. The software was designed and written for interactive display and plotting. Automatic plotting of large data files is facilitated by a batch plotting mode. The user can define display formats for the analysis of noise and vibration problems in the electric utility, chemical processing, paper, and automotive industries. This paper describes the history and development of graphics capabilities of the MIDAS system. The system, as illustrated in the examples, has proven efficient and economical for displaying large quantities of data.

<p>Since 2017, Open Data has been a part of the DWD data distribution strategy. Starting with a small selection of meteorological products, the number of available datasets has grown continuously over the last years. Since the start, users can access datasets anonymously via the website https://opendata.dwd.de to download file-based meteorological products. Free access and the variety of products has been welcomed by the general public as well as private met service providers. The more datasets are provided in a directory structure, however, the more tedious it is to find and select among all available data. Also, metadata and documentation were available, but on separate public websites. This turned out to be an issue, especially for new users of DWD's open data.</p><p>To help users explore the available datasets as well as to quickly decide on their suitability for a certain use case, the Open Data team at DWD is developing a geoportal. It enables free-text search along with combined access to data, metadata, and description along with interactive previews via OGC WMS.</p><p>Cloud technology is a suitable way forward for hosting the geoportal along with the data in its operational state. Benefits are expected for the easy integration of rich APIs with the geoportal, and the flexible and fast deployment and scaling of optional or prototypical services such as WMS-based previews. Flexibility is also mandatory to respond to fluctuating user demands, depending on time of day and critical weather situations, which is supported by containerization. The growing overall volume of meteorological data at DWD may mandate to allow customers to bring their code to the data – for on-demand processing including slicing and interpolation –  instead of transferring files to every customer. Shared cloud instances are the ideal interface for this purpose.</p><p>The contribution will outline a protoype version of the new geoportal and discuss further steps for launching it to the public.</p>

Activity and emotion recognition based on physiological signal processing in health care applications is a relevant research field, with promising future and relevant applications, such as health at work or preventive care. This paper carries out a deep analysis of features proposed to extract information from the electrocardiogram, thoracic electrical bioimpedance, and electrodermal activity signals. The activities analyzed are: neutral, emotional, mental and physical. A total number of 533 features are tested for activity recognition, performing a comprehensive study taking into consideration the prediction accuracy, feature calculation, window length, and type of classifier. Feature selection to know the most relevant features from the complete set is implemented using a genetic algorithm, with a different number of features. This study has allowed us to determine the best number of features to obtain a good error probability avoiding over-fitting, and the best subset of features among those proposed in the literature. The lowest error probability that is obtained is 22.2%, with 40 features, a least squares error classifier, and 40 s window length.

The peculiarities of financial audits conducted by the Accounting Chamber of Ukraine according to a methodology that meets the requirements of ISSAI are explored. The Financial Audit Manual with detailed instructions, audit procedures, and templates of audit documentation, elaborated by the Accounting Chamber and international partners in 2019, is considered. The analysis of the experience of 31 European SAIs showed that most of SAIs do not publish audit manuals, in particular, only SAI of Albania, Georgia, Lithuania, Moldova, and Romania provided free access to financial audit manuals. The methodological recommendations for conducting the financial audit by the Accounting Chamber of Ukraine, adopted and published in 2015, cover all the issues that are outlined in such manuals of SAIs from those countries..Besides, the risks of providing open access to the Financial Audit Manual, elaborated by the Accounting Chamber of Ukraine were detected. They are the risks of fraud by officials of audited entities, not detecting a material risks by auditors, the use of intellectual property of the Accounting Chamber for commercial purposes by other entities and reputational risks due to breach of agreements with international partners involved in the development of the manual. The Financial Audit Manual was tested on six financial audits conducted by the Accounting Chamber in 2019 and main results are analyzed in the paper. Significant deficiencies of internal control, fraud risks and risks associated with accounting, budgeting and financial reporting software, and the need of improvement in accounting policies, internal control and workflow in all audit entities were identified. Additionally,, the audit results are presented in a user-friendly format tailored to the needs of decision- makers, with an emphasis on issues that require rapid response. Based on the conducted analysis, the conclusions about the low quality of financial and budgetary reporting of public sector entities and the systematic nature of identified problems and risks were made. Thus, the importance of financial audits was emphasized and the proposals for further improvement of this type of audit of the Accounting Chamber were elaborated. In particular, updating of the legislation and internal documents, usage of modern information technologies and software for audits, translation of ISSAI, training for staff, changes in personnel policy, improvement of the quality control system.

SummaryMicroRNAs (miRNAs/miRs) are important cellular components that regulate gene expression at posttranscriptional level. Various upstream components regulate miR expression and any deregulation causes disease conditions. Therefore, understanding of miR regulatory network both at upstream and downstream level is crucial and a resource on this aspect will be helpful. Currently available miR databases are mostly related to downstream targets, sequences, or diseases. But as of now, no database is available that provides a complete picture of miR regulation in a specific condition.Our miR regulation web resource (miReg) is a manually curated one that represents validated upstream regulators (transcription factor, drug, physical, and chemical) along with downstream targets, associated biological process, experimental condition or disease state, up or down regulation of the miR in that condition, and corresponding PubMed references in a graphical and user friendly manner, browseable through 5 browsing options. We have presented exact facts that have been described in the corresponding literature in relation to a given miR, whether it’s a feed-back/feed-forward loop or inhibition/activation. Moreover we have given various links to integrate data and to get a complete picture on any miR listed. Current version (Version 1.0) of miReg contains 47 important human miRs with 295 relations using 190 absolute references. We have also provided an example on usefulness of miReg to establish signalling pathways involved in cardiomyopathy. We believe that miReg will be an essential miRNA knowledge base to research community, with its continuous upgrade and data enrichment.This HTML based miReg can be accessed from: www.iioab-mireg.webs.com or www.iioab.webs.com/mireg.htm.

Abstract DNAproDB (https://dnaprodb.usc.edu) is a web-based database and structural analysis tool that offers a combination of data visualization, data processing and search functionality that improves the speed and ease with which researchers can analyze, access and visualize structural data of DNA–protein complexes. In this paper, we report significant improvements made to DNAproDB since its initial release. DNAproDB now supports any DNA secondary structure from typical B-form DNA to single-stranded DNA to G-quadruplexes. We have updated the structure of our data files to support complex DNA conformations, multiple DNA–protein complexes within a DNAproDB entry and model indexing for analysis of ensemble data. Support for chemically modified residues and nucleotides has been significantly improved along with the addition of new structural features, improved structural moiety assignment and use of more sequence-based annotations. We have redesigned our report pages and search forms to support these enhancements, and the DNAproDB website has been improved to be more responsive and user-friendly. DNAproDB is now integrated with the Nucleic Acid Database, and we have increased our coverage of available Protein Data Bank entries. Our database now contains 95% of all available DNA–protein complexes, making our tools for analysis of these structures accessible to a broad community.
