A Neighborhood-level Perspective of Real Estate Determinants in Three U.S. Cities

This study examines the relationships between commonly available socio-economic and environmental determinants of real estate (crime, quality of schools, racial/ethnic diversity, and built environment) and real estate values in socially and politically recognized units in the three largest cities of the U.S.—New York, Los Angeles, and Chicago. Utilizing a variety of data sources used by potential real estate buyers, we conduct correlations, mapping, and multiple regression analyses to identify the degrees and strengths of associations between select determinants and real estate values at these politically recognized units. Results suggest that the cities exhibit similar patterns for crime-related characteristics and quality of schools. However, the characteristics such as population density, vacancy rates, and especially the ethnic/racial diversity of these recognized units demonstrate nuanced differences with real estate values across the three cities

Parallel Implementation of Numerical Solution of Few-Body Problem Using Feynman’s Continual Integrals

Modern parallel computing algorithm has been applied to the solution of the few-body problem. The approach is based on Feynman’s continual integrals method implemented in C++ programming language using NVIDIA CUDA technology. A wide range of 3-body and 4-body bound systems has been considered including nuclei described as consisting of protons and neutrons (e.g., 3,4He) and nuclei described as consisting of clusters and nucleons (e.g., 6He). The correctness of the results was checked by the comparison with the exactly solvable 4-body oscillatory system and experimental data

Synergy of Nuclear Data and Nuclear Theory Online

The paper describes the NRV web knowledge base on low-energy nuclear physics developed in the Joint Institute for Nuclear Research. The NRV knowledge base working through the Internet integrates a large amount of digitized experimental data on the properties of nuclei and nuclear reaction cross sections with a wide range of computational programs for modeling of nuclear properties and nuclear dynamics. Today, the NRV becomes a powerful instrument for nuclear physics research as well as for educational applications. Advantages of the functioning scheme of the knowledge base provide the synergy of coexistence of the experimental data and computational codes within one platform

Научные журналы по библиотековедению, библиографоведению и книговедению: история, реалии, перспективы

The article presents the presentations of the participants of the round table “Scientific Journals on Library Science, Bibliography Science and Book Studies: History, Realities, Prospects (to the 70th anniversary of the journal “Bibliotekovedenie” (Library Science)”, which took place on April 19, 2022 within the framework of the International Scientific and Practical Conference “Rumyantsev Readings — 2022”. The paper reflects the place and role of the professional scientific journals in the development of communications that contribute to the preservation of libraries as cultural heritage institutions and form the human capital and cultural potential of all generations of Russian citizens.The journal “Library Science”, established in 1952, became the nationwide scientific periodical of the library sector. Participants described in their speeches the characteristics of the publication activity of some Russian journals, professional periodicals of Belarus, Kazakhstan, Azerbaijan and the international scientific journal “Libri”. The authors highlighted the peculiarities of the creation of periodicals of the designated subject, their functioning, the management models used, the diversity of elements of publication policy and design: regional differences, typological characteristics of the founders, departmental affiliation, cultural traditions, the uniqueness of the historical conditions of creation, etc.The discussion resulted in unanimous recognition of the significant role of professional scientific periodicals in supporting the scientific infrastructure of libraries and providing methodological support of the sector, including research practices, as well as atmosphere of creativity and creative competencies. In the future, the journals are considered as points of growth of professional knowledge, interdisciplinary thinking and cultural communications, activators of the socio-cultural space.Представлены выступления участников круглого стола «Научные журналы по библиотековедению, библиографоведению и книговедению: история, реалии, перспективы (к 70-летию журнала “Библиотековедение”)», который состоялся 19 апреля 2022 г. в рамках Международной научно-практической конференции «Румянцевские чтения — 2022». Отражены место и роль профессиональных научных журналов в развитии коммуникаций, способствующих сохранению библиотек как учреждений культурного наследия и формирующих человеческий капитал и культурный потенциал всех поколений граждан России.Журнал «Библиотековедение», созданный в 1952 г., стал общенациональным научным периодическим изданием библиотечной отрасли, задачи которого в разные периоды фокусировались на проблемах становления библиотек как активных участников процессов, происходящих в обществе, и их отражении в научных исследованиях. «Библиотековедение» остается признанным и наиболее авторитетным журналом.В выступлениях участников были отмечены характеристики публикационной активности некоторых российских журналов, профессиональной периодики Беларуси, Казахстана, Азербайджана и международного научного журнала Libri.Выделены особенности создания периодических изданий обозначенной тематики, их функционирования, используемых управленческих моделей, разнообразие элементов публикационной политики и оформления: региональные различия, типологические характеристики учредителей, ведомственная принадлежность, культурные традиции, уникальность исторических условий создания и др.Итогом обсуждения стало единодушное признание значимой роли профессиональной научной периодики в поддержке научной инфраструктуры библиотек и методического обеспечения отрасли, включая исследовательские практики, атмосферу творчества и креативных компетенций. В перспективе журналы рассматриваются как точки роста профессиональных знаний, междисциплинарного мышления и культурных коммуникаций, активаторы социокультурного пространства

"Flora of Russia" on iNaturalist: a dataset

The "Flora of Russia" project on iNaturalist brought together professional scientists and amateur naturalists from all over the country. Over 10,000 people are involved in the data collection.Within 20 months the participants accumulated over 750,000 photo observations of 6,853 species of the Russian flora. This constitutes the largest dataset of open spatial data on the country’s biodiversity and a leading source of data on the current state of the national flora. About 85% of all project data are available under free licenses (CC0, CC-BY, CC-BY-NC) and can be freely used in scientific, educational and environmental activities
