The efficient computation of molecular integrals and their derivatives is a crucial step in molecular property evaluation in modern quantum chemistry. As an integral tensor decomposition technique, the density-fitting (DF) approach becomes a popular tool to reduce the memory and disk requirements for the electron repulsion integrals. In this study, an application programming interface (API) framework, denoted Molint (MFW), for the computation of molecular integrals and their first derivatives, over contracted Gaussian functions, for the density-fitted methods is reported. The MFW is free software and it includes overlap, dipole, kinetic, potential, metric, and 3-index integrals, and their first derivatives. Furthermore, the MFW provides a smooth approach to build the Fock matrix and evaluate analytic gradients for the density-fitted methods. The MFW is a C++/Fortran hybrid code, which can take advantage of shared-memory parallel programming techniques. Our results demonstrate that the MFW is an efficient and user-friendly API for the computation of molecular integrals and their first derivatives.

AbstractA multitude of factors contribute to complex diseases and can be measured with “omics” methods. Databases facilitate data interpretation for underlying mechanisms. Here, we describe the Virtual Metabolic Human (VMH, http://vmh.life) database encapsulating current knowledge of human metabolism within five interlinked resources “Human metabolism”, “Gut microbiome”, “Disease”, “Nutrition”, and “ReconMaps”. The VMH captures 5,180 unique metabolites, 17,730 unique reactions, 3,288 human genes, 255 Mendelian diseases, 818 microbes, 632,685 microbial genes, and 8,790 food items. The VMH’s unique features are i) the hosting the metabolic reconstructions of human and gut microbes amenable for metabolic modeling; ii) seven human metabolic maps for data visualization; iii) a nutrition designer; iv) a user-friendly webpage and application-programming interface to access its content; and v) user feedback option for community engagement. We demonstrate with four examples the VMH’s utility. The VMH represents a novel, interdisciplinary database for data interpretation and hypothesis generation to the biomedical community.

Abstract tRNAs have been widely studied for their role as genetic code decoders in the ribosome during translation, but have recently received new attention due to the discovery of novel roles beyond decoding, often in connection with human diseases. Yet, existing tRNA databases have not been updated for more than a decade, so they do not contain this new functional information and have not kept pace with the rate of discovery in this field. Therefore, a regularly updated database that contains information about newly discovered characteristics of tRNA molecules and can be regularly updated is strongly needed. Here, we report the creation of the T-psi-C database (http://tpsic.igcz.poznan.pl), an up-to-date collection of tRNA sequences that contains data obtained from high-throughput tRNA sequencing, e.g. all isoacceptors and isodecoders for human HEK293 cells. This database also contains 3D tRNA structures obtained from Protein Data Bank and generated using homology modeling. The T-psi-C database can be continuously updated by any member of the scientific community, and contains its own application programming interface (API), which allows users to retrieve or upload data in JSON format. Altogether, T-psi-C is user-friendly, easy to develop and an up-to-date source of knowledge about tRNAs.

The paper examines the necessity and possibility of interface interaction of the information modeling program Revit Autodesk with the common office program MS Excel. Such interaction makes it easier to prepare project documentation in accordance with the requirements of Russian standards, GOST. An analysis of the capabilities of the built-in Revit tools for creating specifications and their design according to GOST requirements showed an insufficient level of automation of these processes. Ready-made foreign and Russian solutions in the field of Revit plugins that implement interaction with Excel have a number of disadvantages. The purpose of this article is to demonstrate the capabilities of the application programming interface (API) for creating applications using the example of a developed software solution for automating the unloading of information from a BIM model into an Excel electronic document, in order to bring data presentation standards in line with GOST requirements. The application is developed using a tool environment: the C# programming language, the MS Visual Studio development environment, the WPF user interface creation tool, the Revit-side application programming interface .Net API, an interface for interacting with Excel ClosedXML files. As a result, the interface of the developed plugin is presented. The program allows you to export documents-statements and specifications - to Excel, designed according to the requirements of GOST. The user-friendly tab-based user interface, the compliance of the program design with the Revit system and the implemented functionality give the program advantages over its analogues. The application is available for free download to any Revit user, which is of practical importance.

Operasional sektor perkebunan di Indonesia sebagian besar masih mengandalkan sistem konvensional yang menggunakan tenaga manusia untuk melakukan kontrol ke lapangan. Dengan kondisi tersebut, masih sulit jika ingin melakukan peningkatan kinerja operasional menjadi lebih efisien, efektif, dan produktif. Ditambah lagi, kondisi pandemi yang tengah dihadapi saat ini secara tidak langsung sangat berdampak dan berpotensi menurunkan angka produktivitas. Sistem operasional ataupun pengelolaan lahan perkebunan harus mengalami perubahan. Pemanfaatan teknologi dan inovasi sangat dibutuhkan untuk membantu mempertahankan ataupun meningkatkan kualitas dan kuantitas hasil produksi. Oleh sebab itu, dibutuhkan suatu rancangan sistem informasi berbasis website, yang bekerja menyampaikan informasi kondisi geografis suatu area secara real-time sebagai solusi dari permasalahan pemantauan kondisi geografis. Sistem informasi tersebut bekerja menggunakan informasi berupa data spasial (bereferensi geografis) yang dikenal dengan Sistem Informasi Geografis atau Geographic Information System (GIS).Tujuan penelitian ini adalah untuk  membangun GIS berbasis web guna memberikan informasi dan menggambarkan kondisi (normal, rawan, kritis) pada suatu area/lahan secara real-time. Metode penelitian ini terdiri dari lima tahapan, yaitu persiapan penelitian (studi literatur), pengkajian objek (observasi, analisis kebutuhan sistem), perancangan dan pembangunan GIS dan integrasi dengan IoT, analisis dan pengujian penerapan GIS, serta penarikan kesimpulan. Sistem informasi geografis yang dibuat adalah dengan menampilkan peta (maps) area yang dipantau. Perangkat lunak yang digunakan untuk menampilkan maps adalah Google Maps Platform yang mana pada platform tersebut terdapat interface yang disebut API (Application Programming Interface). Google Maps API digunakan untuk menghubungkan sistem informasi geografis yang berbasis website dengan google maps. GIS memberikan informasi dan menggambarkan kondisi geografis suatu area secara real-time, kondisi area yang normal ditandai dengan warna hijau, kondisi antara (rawan kritis) ditandai dengan warna kuning serta kondisi area yang kritis ditandai dengan warna merah. Dengan adanya sistem informasi geografis, maka membantu para pekerja lapangan dalam memantau kondisi geografis suatu area secara real-time tanpa harus berada langsung di lokasi. Berdasarkan hasil penilaian pengguna, sebagian besar menyatakan “sangat setuju” bahwa GIS ini bermanfaat, bersifat user-friendly, mudah diakses kapanpun dan di manapun, serta memiliki kecepatan akses yang baik. Selain itu, sebagian besar juga menyatakan “setuju” bahwa GIS mampu menampilkan informasi yang akurat dan dapat membantu pekerjaan.
