Published: December 2024

Addressing these water management challenges requires a comprehensive and integrated approach. Floods and other water-related challenges in urban areas can have an impact on land values. However, the lack of studies has developed a comprehensive index methodology related to examining floods and land value relationships for urban areas. Therefore, the main purpose of this study is to develop a comprehensive index methodology related to examining floods and land value relationships for urban areas that is called a Flood-Adjusted Land Value Index (FALVI) Methodology. This paper illustrates the importance of the proposed FALVI methodology to determine the relationship between flood events and land value. Important variables within three main aspects—environmental, socio, and historical flood variables—would be elaborated and measured by GIS-based analysis. It provides a more accurate and thorough assessment of property values by taking flood risk variables into account throughout the valuation process. This methodology is also regarded as an essential methodology for examining floods and land value links in metropolitan areas. FALVI can help guide government strategies on flood management, land use planning, and catastrophe risk reduction. By identifying high-risk locations, governments can prioritize flood mitigation measures and enact restrictions that prevent development in susceptible areas. Urban areas in certain watershed systems can be kept viable for the long term by carefully reviewing this methodology and implementing suitable land management strategies.

Published: December 2024

This study explores the prospective of risperidone-loaded β-cyclodextrin nanosponges as a therapeutic strategy for managing altered mental status (AMS) and delirium in cancer patients. Almost 87% of patients with advanced cancer experience AMS or delirium, significantly impacting prognosis and quality of life. The present study aims to enhance the solubility, bioavailability, and therapeutic effectiveness of second-generation antipsychotic medication risperidone (RSP), with poor aqueous solubility, it was encapsulated in β-cyclodextrin nanosponges. The nanosponges prepared by fusion technique using different β-CD: DPC molar ratios, were tested for their ability to encapsulation efficiency, drug loading, and dissolutions kinetics. Batch 1, (1:1 molar ratio) exhibits RSP loading capacity (454.2 µg/mg) and encapsulation efficiency (90.84%) along with DSC and FTIR also confirmed that the RSP was successfully encapsulated and without any chemical interactions. In vitro dissolution studies demonstrated a biphasic release profile, with an initial burst followed by sustained release, governed by Fickian diffusion as confirmed by release kinetics modeling. The improved solubility and dissolution profile of the nanosponges will be significant to improve risperidone delivery, ensuring better symptom management in a vulnerable population. These findings highlight the potential of β-cyclodextrin nanosponges as an innovative and adaptable platform for enhancing antipsychotic drug delivery.

Lepidocephalichthys guntea, commonly known as loach, is a popular freshwater fish found in various water bodies. This study collected 210 specimens (148 females, 62 males) from fish markets in Noakhali, Bangladesh, to measure various length, weight, gonado-somatic index (GSI), fecundity and condition factor. To establish correlations, the relationships between length-length, length-weight, and GSI with both length and weight were analyzed. Body weight ranged from 1.99 to 8.89 g (mean 4.21 ± 1.49 g), and total length from 6.5 to 10.3 cm (mean 7.91 ± 0.77 cm). GSI peaked in June (8.63±1.16%), followed by May (6.58±0.89%), with the lowest values in September (0.01%). Mean fecundity was 7415.3±1168.54 in May and June (spawning season). The condition factor (KF) was highest (1.04) in fish between 9.5–10.4 cm and lowest (0.87) in the 7.5–8.4 cm group. The coefficient of correlation (r2) values showed a strong positive relationship between body weight (BW) and both total length (TL) and standard length (SL). Moderate positive correlations were found between BW and head length (HL), and BW and body circumferences (BD) in pooled and female samples. However, in male, the correlations for BW vs. HL, BW vs. BD, as well as TL vs. HL and TL vs. BD, were asymmetrical. The relationships between GSI and both BW and gonad weight (GW) showed moderate positive correlations. Conversely, the coefficient of correlation between GSI and TL in the pooled sample, and GSI with both TL and BW in males, were indicating weak correlations. This study will provide valuable insights for conservation policymakers and hatchery owners, aiding in efforts to prevent the extinction of this species in the wild.

A hydroacoustic survey of the distribution of aggregations of Macrohectopus branickii (Amphipoda) in Barguzinsky Bay of Lake Baikal was conducted for the first time in the last 30 years. The hydroacoustic complex “Echo-Baikal” was used in the research. Verification of hydroacoustic data is based on the results of synchronous net catches with a JOM net. The present study demonstrates that macrohectopus aggregations are confined to slope zone areas with depths of 100–150 m. The dependence between the strength of the mean volume backscattering and the density of macrohectopus was obtained, based on which its biomass in Barguzinsky Bay was estimated at 2.7·106 kg.

Published: December 2024

Biodiversity is the mainstay of mankind and crucial for ecosystem functions. Although so, it is not stable and changing pattern of biodiversity are discernible worldwide on account of biological or plant invasion. Plant species are invaded intentionally, naturally or accidentally. Before embarking upon any developmental activities in a region, we have to take a stock of scenario about the status of biodiversity. In this regard, the present author made a headway collecting evidences of plant invasion (bioinvasion) on Indian subcontinent. Kalidasa's ancient Sanskrit scripts viz., Abhigyanshakuntalam, Meghaduta, Raghuvansham and Kumarsambhavam have been assessed from the viewpoint of plant invasion in India, the results of this study are being presented in this communication. This account may aid in the history of bioinvasion in India in view of biodiversity management.

Published: December 2024

The Digital Botanical Repository at Universiti Utara Malaysia (UUM) is an initiative designed to support the conservation and study of herbal plants, reflecting the region's rich biodiversity. This repository aims to bridge the gap between the physical herbal plant garden and a wider audience by providing detailed plant profiles and advanced search functions online. The problem addressed by this study is the limited accessibility and engagement with the herbal plant garden's resources. Despite the garden's potential as a useful educational and research tool, physical access is limited, and there is a need for a more efficient way to disseminate information about the herbal plants it houses. The objective of the repository is to improve access to and engagement with the garden's resources, enhance research capabilities, and support educational initiatives. By digitizing the plant information and making it available online, the project seeks to reach a broader audience and promote the garden's use in various academic and research contexts. The methodology for developing the repository involved several key phases: conducting a requirement analysis to understand user needs, designing a database to store extensive botanical data and high-resolution images, creating a user-friendly and scalable interface, integrating the database with the interface, and implementing advanced search functionality. Usability testing was conducted using the Website Analysis and Measurement Inventory (WAMMI) framework to ensure a high standard of user experience. The findings from usability testing indicated that while users generally found the repository effective and engaging, there were issues with efficiency, error tolerance, and ease of learning. For instance, 49% of users agreed that the website seemed logical, but some experienced difficulties with navigation and search functionalities. The impact of this study is significant for botanical conservation and research. By addressing the identified usability issues and implementing suggested enhancements such as interactive educational tools, user-generated content, multilingual support, and collaborations with other botanical institutions, the repository can further its role as an invaluable resource.
Принцип двойственности в математической теории общего равновесия
Authors: Козырев А.Н. 
Published: December 2024

В статье излагается подход к математической теории экономического равновесия на основе последовательного применения принципа двойственности, привнесенного Л.В. Канторовичем из функционального анализа в выпуклый анализ, в линейное программирование и в экономику. Показано, что, следуя принципу двойственности, можно переписать все элементы известных моделей экономического равновесия на языке сопряженных пространств, сопряженных конусов и сопряженных полиэдров. Это позволяет очистить математические конструкции, используемые в теории общего экономического равновесия, от шлейфа идеологических догм, придать им в отдельных случаях новую интерпретацию и эффективно использовать в реальной экономике.
The article describes an approach to the mathematical theory of economic equilibrium based on the consistent application of the duality principle introduced by L.V. Kantorovich from functional analysis to convex analysis, linear programming and economics. It is shown that, following the principle of duality, it is possible to rewrite all the elements of known models of economic equilibrium in the language of conjugate spaces, conjugate cones and conjugate polyhedra. This makes it possible to clear the mathematical constructions used in the theory of AER from the plume of ideological dogmas, to give them a new interpretation in some cases and to use them effectively in the real economy.

Authors: Белоусов Ф.А. , Иванова А.К. , Неволин И.В. 
Published: December 2024

Экономическая модернизация и технологическое развитие страны всё больше связывают с мерами по укреплению международного сотрудничества и развитию возможностей взаимодействия в области высоких технологий. Если в 2015 г. развитие получили меры по усилению диалога между государством и бизнесом (деловые форумы с представителями органов власти, программы поддержки малого и среднего бизнеса, меры поддержки экспортеров), то сегодня на фоне ужесточения глобальной технологической конкуренции, роста протекционизма и феномена экстерриториальных экономических ограничений, внимание обращено на развитие международного технологического сотрудничества. Причём последнее приобретает не только стратегическую значимость, но, попадая в сферу экономической безопасности России, также получает иное наполнение в качестве объекта исследования. Новое понимание этого явления показал прошедший в сентябре 2024 года Международный технологический конгресс. Его центральной темой стало технологическое партнёрство и возможности для его развития между странами, в том числе, в рамках БРИКС. Отраслевые вопросы красной нитью связывала тема сотрудничества, надежного и долгосрочного партнёрства как основы технологического суверенитета. Данная статья вносит вклад в обсуждение темы технологического суверенитета, представляя позицию бизнеса в сообщениях участников конгресса. Эта позиция соотносится с возможными барьерами на пути к технологическому суверенитету и научными методами их преодоления. Подробного рассмотрения заслужили технологии искусственного интеллекта как одно из направлений сотрудничества и достижения в этой сфере, озвученные участниками конгресса.
Economic modernization and technological development are increasingly associated with measures to strengthen international cooperation. In 2015, measures were developed to strengthen the dialogue between the government and business. Nowadays, however, the intensification of global technological competition, the growth of protectionism and the phenomenon of extraterritorial economic restrictions move the focused on the international technological cooperation. The latter has strategic importance and receives a different content as an object of research. A new understanding of this phenomenon was shown by the International Technological Congress held in September 2024. Its central theme was technological partnership and opportunities for its development between countries, including BRICS platform. The theme of cooperation, reliable and long-term partnership as the basis of technological sovereignty threaded the industry issues. This article contributes to the discussion of the topic of technological sovereignty by presenting the position of business in the messages of the congress participants. This position correlates with possible barriers to technological sovereignty and scientific methods of overcoming them. Artificial intelligence deserves detailed consideration as one of the areas of cooperation, according to the participants of the congress.

Published: December 2024

В данной работе рассматривается задача многопериодного прогнозирования реализованной волатильности (realized volatility, ) и системного бэк-тестирования торговых стратегий для опционов на торгуемые биржевые фонды (Exchange-Traded Fund, ETF). Цель исследования – построение моделей глубокого обучения для многопериодного прогнозирования волатильности активов, таких как SPY и QQQ, и проверка эффективности прогнозов в рамках бэк-тестирования опционных стратегий. Для прогнозирования было использовано несколько архитектур нейронных сетей: LSTM, GRU, BiLSTM, BiGRU, FNN и NBEATSx, а также базовая эконометрическая модель HAR-RV для сравнения. В исследовании вводится новая функция потерь, квантильный лог-гиперболический косинус, для повышения точности прогнозов на высоких значениях волатильности. Точность моделей оценивалась на основе метрик MSE, MAE, MAPE и скорр. , что показало превосходство рекуррентных архитектур. С целью апробации в условиях различных рыночных сценариев полученные прогнозы реализованной волатильности были использованы в бек-тестировании двух опционных стратегий: стрэддл и v-скальпинг.

Published: December 2024

Сенсорная активность мозга является необходимым компонентом психических и физиологических процессов, связанных с восприятием информации и возникновением различных заболеваний, в том числе обусловленных нарушением периферических границ поля зрения, отслоением сетчатки глаза и других. В данной статье рассматривается возможность создания отечественного аналога периметра для офтальмологической диагностики полей зрения. Глаукома прогрессирует, не вызывая симптомов, пока заболевание не достигнет стадии тяжелого повреждения нервов. Для замедления прогрессирования заболевания необходимо раннее вмешательство и наблюдение за развитием течения болезни. Именно поэтому принято решение изучить возможность использования методов графической обработки периметрических изображений с дальнейшей возможностью использования методов машинного обучения.
Sensory activity of the brain is a necessary component of mental and physiological processes related to the perception of information and the occurrence of various diseases, including those related to the violation of peripheral boundaries of the visual field, retinal detachment, etc. with the eyes. This article considers the issue of creating a domestic analog of perimeter for ophthalmologic diagnostics of visual fields. Since glaucoma progresses without causing symptoms until the disease reaches the stage of severe nerve damage. To slow down the progression of the disease, early intervention and monitoring of the course of the disease is necessary. That is why we decided to study the possibility of using methods of graphical processing of perimetric images with further possibility of training a neural network.
