НЕРАВНОМЕРНОЕ РАЗВИТИЕ РЕГИОНОВ РОССИИ В КОНТЕКСТЕ ИНФРАСТРУКТУРНОЙ ФИНАНСИАЛИЗАЦИИ
Authors: ВАСИЛЬЕВ Д.К. , ЛИМОНОВ Л.Э. 
Published: January 2025

Влияние государственных и частных инвестиций в инфраструктуру на сокращение региональных неравенств пока еще не получило достаточного научного внимания, особенно в контексте стран БРИКС, в том числе в России (несмотря на важность проблемы и ее исследования в ряде стран, в частности в Китае). Восполняя этот пробел, настоящая статья посвящена вопросам оценки влияния инфраструктурной финансиализации на неравномерность регионального развития в России. С использованием регрессионной модели Тобита и панельных данных за период с 2005 по 2019 г. в исследовании измеряются характеристики неравномерного регионального развития в России. Инфраструктурная финансиализация задействована в качестве основной объясняющей переменной. Полученные результаты показывают, что развитие инфраструктурной финансиализации ведет к снижению неравномерности регионального развития в России. Несмотря на то что российская экономика полностью ориентирована на государственное управление, необходимо увеличивать объемы регионально пропорциональных частных инвестиций в инфраструктуру для конвергенции регионов. При этом настоящее исследование отличается от предыдущих, проведенных в других странах с использованием аналогичной методологии, что подчеркивает спорный характер данной темы.
This article addresses the insufficient scientific attention given to the impact of public and private infrastructure investments on reducing regional inequalities, especially within the BRICS countries, and particularly Russia. Despite the importance of this issue, it has been under-researched there, unlike in other countries such as China. To bridge this gap, the article evaluates how infrastructural financialization influences uneven regional development in Russia. Using a Tobit regression model and panel data from 2005 to 2019, the study analyzes regional development disparities, with infrastructural finanicate that advanced infrastructural financialization contributes to reducing regional inequality in Russia. Although Russia’s economy focuses on public administration, the article emphasizes the need for increased regionally proportional private investment in infrastructure to achieve regional convergence. Notably, the study’s conclusions differ from those of studies using similar methodology abroad, highlighting the controversial nature of the topic.
ОЦЕНКА ВКЛАДА КОМПАНИЙ РАЗНОГО ВОЗРАСТА И РАЗМЕРА В РАЗВИТИЕ РЕГИОНАЛЬНЫХ РЫНКОВ

Следуя за теориями, изучающими причины и факторы роста компаний, данная статья фокусирует внимание на выделении растущих компаний как важного элемента в развитии высокотехнологичного бизнеса. В статье разрабатывается методика, позволяющая идентифицировать ключевые для регионального рынка категории компаний, определяющие его динамику. Региональный рынок понимается здесь как совокупность компаний, находящихся в данном регионе. Категоризация компаний проводится на основе группировки компаний по размеру (четыре уровня) и возрасту (четыре уровня), так что компании каждого региона объединяются в 16 размерно-возрастных групп. Разработанная методика проверяется на примере развития высокотехнологичного бизнеса в восточных регионах России. Показано, что несмотря на то что структура выручки высокотехнологичного бизнеса различается по регионам, доминирующими во всех регионах являются крупные зрелые компании. Оценка вклада различных размерно-возрастных групп в динамику общей региональной выручки позволила выделить группы, являющиеся локомотивами роста в каждом регионе. Представляется, что государственная поддержка этих групп компаний может оказать большее влияние на развитие экономики региона. Предложенная методика может быть использована для анализа динамики развития других отраслей и регионов.
This article, building on theories that explore the causes and factors of company growth, focuses on identifying growing companies as a key element in developing high-tech businesses. It presents a methodology for categorizing companies that influence regional market dynamics, where the regional market is defined as the set of companies within a specific region. The categorization is based on company size (four levels) and age (four levels), grouping companies from each region into 16 distinct size and age categories. This methodology is tested against high-tech business development in Russia’s eastern regions. Despite regional variations in the revenue structure of high-tech businesses, large mature companies are found to dominate across all regions. Analyzing the contribution of different size and age groups to overall regional revenue growth reveals the groups driving growth in each region. Targeted state support for these key groups could have a more significant impact on regional economic development. The proposed methodology can also be applied to assess growth dynamics in other industries and regions.
УКОРЕНЕННЫЙ СЕКТОР ЭКОНОМИКИ В СИБИРСКИХ РЕГИОНАХ
Authors: СЫСОЕВА Н.М. 
Published: January 2025

Для выявления внутренних ресурсов развития территории на основе человеческого капитала в данной работе выделен сектор регионального хозяйства, связанный с экономической активностью местного населения. Для характеристики сектора использовано понятие укорененности экономических действий в региональном сообществе. Критерием укорененности экономики предложено считать долю доходов местного населения от предпринимательства и собственности, отражающую степень вовлеченности в рыночные отношения регионального сообщества как субъекта экономических процессов. Рассматриваются пространственные различия в степени укорененности с выделением ресурсных регионов Сибири, где основу экономики составляет деятельность внешних для этих регионов корпораций по добыче и первичной переработке сырья. Степень развития укорененного сектора, особенно в сферах, связанных с интеллектуальной деятельностью, влияет на закрепление наиболее активной и образованной части населения в восточных районах. Результаты исследования могут быть применены в региональном социально-экономическом планировании, которое должно сместить акценты с ресурсного потенциала на человеческий потенциал через приоритетное развитие укорененного сектора экономики.
This study explores internal resources for territorial development based on human capital by identifying a sector of the regional economy associated with the economic activities of the local population. We use the concept of “embeddedness" of economic actions within the regional community to describe this sector. The share of income derived from entrepreneurship and property among the local population is proposed as a criterion for measuring economic embeddedness, reflecting the extent to which the regional community participates in market relations as an economic actor. The analysis highlights spatial differences in the degree of economic embeddedness, notably in Siberian resource regions where external corporations dominate the economy through raw material extraction and primary processing. The development of the embedded sector, especially in areas related to intellectual activity, plays a part in retaining the most active and educated members of the population in eastern regions. The findings can be applied to regional socio-economic planning, advocating a shift from reliance on natural resources to prioritizing human potential by fostering the growth of the embedded economy.

Authors: Moya Lázaro Nancy , Sulca Paredes Teodoro , Chancan Rojas Gladys 
Published: January 2025

En el presente artículo se analiza la solución de la ecuación del calor y de la ecuación de Schrödinger en espacios de Sobolev con peso en RN . Con pesos en la clase Rρ1,ρ2 probamos que la ecuación del calor tiene una única solución, u(t):=S(t)u0, donde {S(t) := eΔt}t≥0 es el semigrupo analítico generado por el operador elíptico lineal de segundo orden, −Δ realizado en el espacio de Banach Lqρ(RN). También se prueba que el operador de Schrödinger −Δ − V (x)I, con potenciales V en espacios localmente uniformes en RN genera un semigrupo analítico SV (t) := e(Δ+V (x)I)t que preserva orden en Lqρ(RN) y tiene los mismos espacios de potencias fraccionarias del −Δ.

Published: January 2025

AbstractThe prosthetic feet available in the market are characterized by high costs and are made of carbon fiber materials, fiberglass, or silicone-coated wood. This study aims to design and manufacture a prosthetic foot to enhance biomechanical performance and user comfort and mimic the natural movement of the human foot; the foot will be designed and manufactured from low-cost materials, namely carbon fiber filaments, using 3D printer technology. The practical part consists of tensile, fatigue tests, and manufacturing the foot using a 3D printer. In this study, the ANSYS program will also analyze the designed model numerically to determine the stresses generated when applying the assumed body weight to the foot model. The results showed that the model is successful in terms of design and does not suffer any mechanical failure during use, in addition to the success of the selection of the material used in the manufacturing process due to its mechanical properties, where the yield stress value = 36.4 MPa, the ultimate stress value = 58.39 Mpa and Young's modulus = 1.23 GPa.
A primer for culturally attuned psychedelic clinical trials
Authors: Ching Terence H. W. , Kelmendi Benjamin 
Published: January 2025

AbstractBackgroundThere is a need to systemically diversify psychedelic clinical trials, considering the growing interest in in the therapeutic potential of psychedelics within Black, Indigenous, and Peoples of Color (BIPOC) and queer communities. Doing so contributes to a more inclusive foundation of evidence-based research and addresses ethical considerations surrounding anticipated demand for these treatments following regulatory approval. Cultural attunement may be key to facilitating effective research and ensuring equitable treatment.AimsHere, we introduce a primer for culturally attuned psychedelic clinical trials. We narratively review prevalent psychological and pragmatic barriers to diversity – as part of set and setting – in modern psychedelic trials. We also propose potential strategies for the culturally attuned recruitment, assessment, and retention of diverse participants.MethodsThis primer narratively synthesizes existing literature on barriers and potential strategies for culturally attuned psychedelic trials. Here, the scope is on classic psychedelics and other drugs with consciousness-altering effects (3,4-methylenedioxy-methamphetamine [MDMA], ketamine). The term ‘diversity’ focuses on BIPOC and sexual- and gender-diverse populations, primarily in the US.ResultsPsychological and pragmatic barriers include stigma, medical mistrust, history of psychedelic-assisted conversion therapy, income disparities, schedule inflexibilities, and transportation inaccessibility. Culturally attuned recruitment, assessment, and retention strategies include queering/diversifying the study team, debinarizing the therapist dyad, developing culturally attuned flyers, community outreach, using culturally attuned language, improving transportation-related access, diversifying room setup, and using culturally attuned assessments.ConclusionsPsychedelic research groups are encouraged to adapt and enact these recommendations in their clinical trials, to improve accessibility to innovative mental health treatments for diverse populations.

Abstract
In alignment with the Materials Genome Initiative and as the product of a workshop sponsored by the US National Science Foundation, we define a vision for materials laboratories of the future in alloys, amorphous materials, and composite materials; chart a roadmap for realizing this vision; identify technical bottlenecks and barriers to access; and propose pathways to equitable and democratic access to integrated toolsets in a manner that addresses urgent societal needs, accelerates technological innovation, and enhances manufacturing competitiveness. Spanning three important materials classes, this article summarizes the areas of alignment and unifying themes, distinctive needs of different materials research communities, key science drivers that cannot be accomplished within the capabilities of current materials laboratories, and open questions that need further community input. Here, we provide a broader context for the workshop, synopsize the salient findings, outline a shared vision for democratizing access and accelerating materials discovery, highlight some case studies across the three different materials classes, and identify significant issues that need further discussion.

La régénération naturelle assistée est un moyen pour réhabiliter des parcs agroforestiers dégradés. Cette étude vise à déterminer la densité optimale d’arbustes à conserver dans les champs de mil au sud du bassin arachidier du Sénégal. Un dispositif en blocs a été installé en milieu contrôlé et en milieu paysan. Les blocs étaient constitués de parcelles de 400 m2 avec 3 niveaux de densités (0, 50 et 100 arbustes/ha) de Combretum glutinosum en milieu contrôlé et 4 niveaux de densités (0, 50, 75 et 100 arbustes/ha) de Combretum glutinosum et de Piliostigma reticulatum en milieu paysan. Le rendement du mil a été mesuré et des échantillons de sol ont été prélevés pour analyser leurs propriétés (C, N…). L’effet de la densité des arbustes sur le rendement des cultures dépend de leur taille. Cet effet est positif ou neutre pour des arbustes majoritairement de C. glutinosum de 1,3 à 3,4 m de hauteur et 0,6 à 2,6 m de diamètre de houppier ; neutre ou négatif pour des arbustes de C. glutinosum de 5,3 m de hauteur et 4,1 m de diamètre de houppier ; négatif pour des arbustes de P. reticulatum de 5,8 m de hauteur et 7 m de diamètre de houppier. Aucun effet significatif n’a été trouvé pour la densité des arbustes sur les teneurs en C organique et N total du sol quelle que soit l’espèce. Au cours des cinq premières années d’adoption de la régénération naturelle assistée, il est recommandé de conserver jusqu’à 100 arbustes de C. glutinosum ou de P. reticulatum/ha sans impacter négativement le rendement des cultures. Au-delà, il est recommandé, soit de réduire le houppier des arbustes, soit de réduire leur densité jusqu’à 50 à 40 arbustes/ha au fur et à mesure que leur taille augmente.

Anisotropy reveals contact sliding and aging as a cause of post-seismic velocity changes

Abstract

Rocks exhibit astonishing time dependent mechanical properties, like memory of experienced stress or slow dynamics, which refers to a transient recovery of stiff-ness after a softening induced by almost any type of loading. This softening and transient recovery is observed in the subsurface and in buildings after earthquake shaking, or in laboratory samples. Our investigation of anisotropy of the slow dynamics effect under uniaxial loading shows that it is observed independent of propagation direction, while the loading effect shows the expected anisotropy originating from the opening and closing of cracks. These observations put a number of novel constraints on the enigmatic physics of slow dynamics. We conclude that transient changes in bulk stiffness are caused by sliding of oblique grain-to-grain contacts and resulting changes in frictional properties as empirically described by rate-and-state friction and observed in laboratory experiments across block contacts. Connecting the nonclassical nonlinearity of heterogeneous materials to the powerful framework of rate-and-state friction provides an elegant explanation for the long searched-for origin of slow dynamics and potentially adds a new perspective for the monitoring of very early stages of material failure when deformation is still distributed in the bulk and just starts to coalesce towards a fracture.
