Anomalous Diffusion and Decay of Clusters of Dopants in Lanthanide-Doped Nanocrystals
Authors: Pawlik Grzegorz , Mitus Antoni C.
Published: February 2025

Upconversion (UC) luminescence in doped lanthanide nanocrystals is associated with the energy migration (EM) process within clusters of dopant ions. The process of the synthesis of core–shell nanocrystals occurs at elevated temperatures, promoting the diffusion of the dopants into the shell accompanied by the decay of dopant clusters. The details of this unwanted effect are poorly understood. In this paper, we theoretically study a model of the diffusion of dopant ions in a nanocrystal using Monte Carlo (MC) simulations. We characterize the diffusion, spatial neighboring relations and clustering of dopant ions regarding the function of reduced temperature and MC time of the heating process. The dopants undergo a weak subdiffusion caused by trapping effects. The main results of this study are as follows: (i) the phase diagram of the variables reduced the temperature and MC time, which separates the enhanced and limited cluster-driven EM regimes, and (ii) a dependence of the average nearest distance between Yb ions as a function of reduced temperature, the concentration of Yb ions and MC time was found. In both cases, the requirements for an effective EM are formulated.

Published: February 2025

Background: Central hypothyroidism is characterized by either decreased TSH or, more commonly, normal TSH. This study aims to check whether this biochemical difference related to the severity of the pituitary disease, metabolic processes and general well-being. Methods: A retrospective analysis was performed on 108 inpatients with hypopituitarism, aged 18–80, hospitalized (1 January 2020, through 31 December 2022) in the Department of Endocrinology and Metabolic Diseases, Medical University of Lodz, Poland. Hypopituitary patients with central hypothyroidism (n = 90) were divided into two subgroups: patients with TSH below normal ranges (low TSH; n = 52) and patients with TSH in reference ranges (normal TSH; n = 38). Results: Among patients with central hypothyroidism, surgical treatment due to pituitary disease was performed more commonly in those with low TSH than in those with normal TSH (65 vs. 42%, p = 0.010). Expectedly, five pituitary deficiencies were diagnosed more commonly in patients with low TSH than in those with normal TSH (46 vs. 13%, p = 0.001). In a regression analysis, the ACTH concentration was the only independent determinant negatively associated with low TSH (also after limiting the analysis to non-treated patients). Regarding lipid profile, decreased HDL cholesterol occurred more commonly in patients with low TSH vs. normal TSH (44% vs. 23%; p = 0.033), which was also observed after the limitation to non-treated patients (47% vs. 21%; p = 0.013). Conclusions: Low TSH in patients with central hypothyroidism is associated with more advanced pituitary disease and less favorable metabolic profile.
A Complementary Metal-Oxide Semiconductor (CMOS) Analog Optoelectronic Receiver with Digital Slicers for Short-Range Light Detection and Ranging (LiDAR) Systems
Authors: Song Yunji , Park Sung-Min
Published: February 2025

This paper introduces an analog differential optoelectronic receiver (ADOR) integrated with digital slicers for short-range LiDAR systems, consisting of a spatially modulated P+/N-well on-chip avalanche photodiode (APD), a cross-coupled differential transimpedance amplifier (CCD-TIA) with cross-coupled active loads, a continuous-time linear equalizer (CTLE), a limiting amplifier (LA), and dual digital slicers. A key feature is the integration of an additional on-chip dummy APD at the differential input node, which enables the proposed ADOR to outperform a traditional single-ended TIA in terms of common-mode noise rejection ratio. Also, the CCD-TIA utilizes cross-coupled PMOS-NMOS active loads not only to generate the symmetric output waveforms with maximized voltage swings, but also to provide wide bandwidth characteristics. The following CTLE extends the receiver bandwidth further, allowing the dual digital slicers to operate efficiently even at high sampling rates. The LA boosts the output amplitudes to suitable levels for the following slicers. Then, the inverter-based slicers with low power consumption and a small chip area produce digital outputs. The fabricated ADOR chip using a 180 nm CMOS process demonstrates a 20 dB dynamic range from 100 μApp to 1 mApp, 2 Gb/s data rate with a 490 fF APD capacitance, and 22.7 mW power consumption from a 1.8 V supply.

Leishmania (Leishmania) infantum chagasi infections range from asymptomatic (AS) to severe visceral leishmaniasis (VL). One of the manifestations is an atypical non-ulcerated cutaneous leishmaniasis (NUCL), which occurs in some locations of Central America with few cases of VL. We conducted a transcriptomic analysis of cell-mediated immunity (CMI) on blood samples from NUCL, AS, VL patients from Amapala, Honduras, and healthy controls. RNA-seq revealed a similar perturbation of gene expression in NUCL and AS. Eight gene signatures of CMI were found in NUCL involved in CD8+ T lymphocyte infiltration, reactive oxygen species generation, PD-1 receptor ligand, inflammasome assembly, chemotaxis, complement receptor and suppressor immune cell infiltration. NUCL was distinguished from VL by its up-regulation of differently expressed genes (DEGs) related to T lymphocyte exhaustion, adhesion and transmigration of leukocytes, and down-regulation of oxidative stress genes. In contrast, VL exhibited up-regulated DEGs involved in antigen cross-presentation, and similar to VL from Brazil, down-regulated DEGs involved in innate immunity. Corroborating the transcriptome findings, both the Leishmanin skin test, and the immunopathology of NUCL skin lesion defined NUCL as a proinflammatory condition, intermediate between the AS and VL clinical outcomes. That condition may be the underlying element for the benign nature of the NUCL.

Published: February 2025

In recent years, mechanical activation technology has been extensively applied as a pretreatment process to increase the leaching efficiency in hydrometallurgical mineral processing. However, studies on its application in the lepidolite bioleaching process are limited. Therefore, the effects of mechanical activation on lithium extraction by an acidophilic iron/sulfur-oxidizing microbial community under different nutrient conditions were evaluated in this study. The solution behavior, phase morphology, and compositional evolution, and microbial community structure succession under eutrophic conditions with exogenous pyrite as the energy substrate and oligotrophic conditions, were investigated. The results revealed that mechanical activation significantly influences the microbial community structure and the interrelationship between microbial activity and mineral phase decomposition and transformation by altering the physical and chemical properties of lepidolite. The best leaching effect was observed in the eutrophic bioleaching groups, followed by the oligotrophic groups at all mechanical activation times. Notably, at a rotation speed of 200 r/min, a material-to-ball mass ratio of 1:20, and an activation time of 150 min, the maximum leaching rates of lithium under eutrophic and oligotrophic conditions were 24.9% and 20.8%, respectively, which were 20.0% and 17.9% higher than those of the nonactivated group. The phase and composition analyses indicated that the dissolution of lithium silicate minerals occurs through a combination of protic acid corrosion, the complexation/electrostatic interactions of extracellular polymeric substances, and the complexation of secondary minerals. These results indicate that the leaching effect is closely related to the pretreatment of mechanical activation, the energy substrates, and the microbial community structure, and this has important reference value for the optimization of the bioleaching process of lepidolite.
Integrated Single Superphosphate with Cattle Manure Increased Growth, Yield, and Phosphorus Availability of Maize (Zea mays L.) Under Rainfed Conditions
Authors: Ali Samraiz , Ali Abid
Published: February 2025

Mostly, phosphorus (P) fertilizers are fixed in the interlayer of soil and become unavailable to crop plants. Combined inorganic fertilizers with organic manures could be a suitable solution to release these nutrients from the soil. P deficiency in soil adversely affected crop growth and development to a larger extent. To check out this problem, present research was conducted over a two-year period to evaluate the efficiency of a combined mixture of inorganic P and organic manure as a better farming strategy, in relation to their sole treatments, for enhancing P availability, plant growth, yield and quality, and soil properties. The inorganic source of P was SSP in the form of P2O5, while the organic source was cattle manure mixed with crop residues called farmyard manure (FYM). The experiment consisted of the same six treatments over each year: (i) control (0F+0P), (ii) 45 kg P2O5 ha−1 (45P), (iii) 90 kg P2O5 ha−1 (90P), (iv) 45 kg P2O5 ha−1 + 1000 kg FYM ha−1 (45P+1000F), (v) 1000 kg FYM ha−1 (1000F), and (vi) 2000 kg FYM ha−1 (2000F), using randomized complete block design (RCBD), to five replications. Results demonstrated that the combination of SSP with FYM increased the plant height (27.9%), grain yield (23.4%), and plant P uptake efficiency (43.7%) of maize as compared to sole SSP at 90 kg P2O5 ha−1, which occurred due to improved P availability in soil. By comparing sole amendments of P fertilizer sources, FYM-treated plots have performed better in increasing maize growth and yield components such as plant height, dry matter, crop growth rate (CGR), net photosynthetic rate, grain yield, and crude protein (e.g., nitrogen contents); this happened due to enhanced soil chemical properties that might be related to improvement in P level and decreased bulk density of soil. Further, significant positive correlations were exhibited among studied crop and soil data. The plant available P and grain protein contents (N concentration) also showed a significant positive correlation and exhibited higher nitrogen contents under organic amendments of P fertilizer, as compared to inorganic treatments. The study concluded that combined SSP at 45 kg P2O5 ha−1 with organic cattle manure at 1000 kg ha−1 has a great potential for enhancing maize productivity under water deficit conditions. Results of this research may further be improved by including rigorous soil samples and field heterogeneity data between the plots and the years, which will provide more clear findings from a combined mixture of organic and inorganic fertilization.

Published: February 2025

Objectives: To assess the effects of agrimol-containing Agrimonia pilosa Ledeb. extract (APE) for senescent immune cell removal in middle-aged Japanese adults with immunosenescence. Design and Setting: A randomized, double-blind, placebo-controlled, parallel-group study was conducted in Japan between June 2023 and April 2024. Participants: 110 individuals aged 40–59, selected based on CD8+ T cells with highly-expressing-senescence-associated-β-galactosidase (SA-βGal). Intervention: Participants were randomly assigned to receive 50 mg APE containing 0.2 mg of agrimols or a placebo for eight consecutive weeks. Measurements: The primary endpoint was the change in the proportion of CD8+ T cells with high SA-βGal expression at 8 weeks of intake from the baseline. The secondary endpoints included the proportion of CD4+ T cells with high SA-βGal expression, CD4+ and CD8+ T cell subsets, and the ratio of various immune cells. Results: Of the 635 subjects screened, 110 with immunosenescence were included in this study. In total, 55 participants in the placebo group and 53 in the APE group completed the intervention. There were no statistically significant changes in either the primary or secondary endpoints due to APE intake. In the male population, the proportion of CD8+ T cells with high SA-βGal expression was reduced by APE intake (p = 0.044). Furthermore, the proportion of naïve CD8+ T cells increased and the number of effector memory CD8+ T cells decreased with the consumption of APE. Conclusions: APE was suggested to reduce senescent immune cells, indicating its potential as a candidate senolytic agent for humans; however, the results of this study are preliminary data, and further research on APE is needed (clinical trial registration: UMIN000051574).

Air pollution in urban centers comes from anthropogenic activities. Tropospheric ozone (O3) depends on chemical precursors that promote an increase in its production, mainly in wind-dominated and large green areas. It is a gas produced by a series of complex chemical reactions catalyzed by sunlight in the atmosphere. It can be concentrated to a greater or lesser extent depending on factors such as the amount of volatile organic compounds (VOCs), the amount of nitrogen dioxide (NO2), the intensity of solar radiation, or by climatic conditions such as temperature and other factors. The objective of this study was to predict tropospheric ozone levels from Land Surface Temperature (LST) data of Landsat 8 in the city of Durango, Dgo. Tropospheric O3 and LST values were obtained from 14 sampling points in the urban area of the city of Durango, of which 11 were obtained by collecting from temperature-monitoring station data and the rest from three fixed monitoring stations established in the city, specifically located in Ministry of Natural Resources and Environment (SRNyMA), Durango Institute of Technology (ITD) and Interdisciplinary Research Center for Regional Integral Development Durango Unit (CIIDIR). A correlation analysis was performed for the 12 months of the year 2023. Subsequently, a linear regression analysis was executed for each month. The results showed a greater positive correlation between O3 concentration and temperature for January (r = 0.91); additionally, this period showed a greater goodness of fit in the prediction of O3 (R2 = 0.91; RMSE = 0.65 ppm). The LST allows for the spatial prediction of ozone concentrations in terms of covering complete urban areas without measuring air stations.

Published: February 2025

Polymer science, a discipline focusing on the synthesis, characterization, and application of macromolecules, has increasingly benefited from the adoption of machine learning (ML) techniques. Among these, Support Vector Machines (SVMs) stand out for their ability to handle nonlinear relationships and high-dimensional datasets, which are common in polymer research. This review explores the diverse applications of SVM in polymer science. Key examples include the prediction of mechanical and thermal properties, optimization of polymerization processes, and modeling of degradation mechanisms. The advantages of SVM are contrasted with its challenges, including computational cost, data dependency, and the need for hyperparameter tuning. Future opportunities, such as the development of polymer-specific kernels and integration with real-time manufacturing systems, are also discussed.

Published: February 2025

Desertification is one of the most severe environmental issues facing the world today, and effective desertification monitoring is critical for understanding its dynamics and developing prevention and control strategies. Although numerous studies on desertification monitoring using remote sensing have been conducted, there remain differences in indicator selection, and a unified monitoring system has yet to be established. In this study, we constructed the Desertification Composite Index (DCI) using Landsat satellite images, integrating six remote sensing indicators reflecting the natural and ecological characteristics of desertified areas. We also incorporated 383 UAV imagery datasets to accurately identify and analyze the spatial and temporal distributions of desertification in the Ring-Tarim Basin from 1990 to 2020 and subsequently assess its spatiotemporal trends. The results show the following: (1) The constructed DCI was used to identify desertification in 2020, achieving an overall accuracy of 0.86 and a Kappa coefficient of 0.8, indicating that the DCI is suitable for extracting regional desertification information. (2) From 1990 to 2020, the area of desertification decreased significantly, with an average annual reduction rate of −0.0022 ha/a, indicating continuous ecological improvement. Despite localized deterioration, the overall trend was one of “general improvement and local containment.” (3) GeoDetector-based analysis showed that cultivated land area and land use type were the primary single-factor drivers of desertification. The interaction between cultivated land and vegetation type exhibited a synergistic effect as a two-factor driver. (4) Desertification in the Ring-Tarim Basin is primarily influenced by human activities. Appropriate management and intervention measures, efficient and intensive cropland management, and rational land use planning can help develop effective strategies to combat desertification.
Behavioral Macroeconomics—A Basis for Developing Sustainable Economic Policies
Authors: Bejenaru Cristina-Elena , Altăr-Samuel Adam , Cheptiș Alexandra , Vid Alin-Ioan
Published: February 2025

This paper contributes to the literature by demonstrating that behavioral macroeconomic models better explain macroeconomic volatility in emerging economies compared to traditional rational expectations frameworks. We explore behavioral macroeconomics as a foundation for sustainable economic policies by comparing New Keynesian models under rational expectations and behavioral heuristics across multiple economies. The model parameters are estimated using the Generalized Method of Moments (GMM) for rational expectations and the Simulated Method of Moments (SMM) for the behavioral framework, evaluating their ability to replicate empirical second moments of output, inflation, and interest rates. The GMM, suited for linear models, provides analytical solutions, ensuring computational efficiency, while the SMM, designed for non-linear models, enables greater flexibility by generating simulated data and departing from restrictive DSGE assumptions. Our findings reveal that the behavioral model—incorporating heterogeneity, heuristic switching, and bounded rationality—better captures the persistent and volatile macroeconomic conditions observed in Central and Eastern European (CEE) economies. In contrast, rational expectations models perform better in advanced economies, where agents rely more on forward-looking information. These results emphasize the need to integrate behavioral features into macroeconomic modeling to enhance empirical accuracy and inform sustainable monetary policy tailored to diverse economic environments.
Scenario-Based Forecasting of the Impact of Tax Incentives on Green R&D in China’s Wind Power Industry in a Complex Network Environment
Authors: Wang Ying , Mayburov Igor A.
Published: February 2025

Due to the deteriorating ecological environment in recent years, many countries have introduced relevant policies to support the development of clean energy. This paper focuses on wind power generation as the subject for examining green R&D diffusion. Many enterprises take advantage of the information asymmetry between them and the government to carry out fake research and development and cheat taxes, resulting in a large loss of fiscal revenue for the state. The aim of the study is to simulate different scenarios for the diffusion of green R&D in China’s wind energy industry under different tax rates, incentives, and penalties. The results of the study show that the state’s ability to increase penalties can inhibit firms’ behavior of camouflaging R&D. Under the current tax incentives, the introduction of green R&D quotas in the electricity market, coupled with strong penalties, can increase the real green R&D capability of enterprises. The government’s implementation of zero R&D tax incentives and strong penalties do not increase firms’ green R&D capabilities. The diffusion effect of green R&D is more significant in the context of strong market demand. This suggests that the introduction of a quota system can encourage firms to accelerate the pace of technological innovation, while a strict regulatory environment is necessary to avoid policy abuse and optimize resource allocation.
UKRAINIAN RED CROSS IN CLAIM CASES AS A SOURCE OF CURRENCY EXTRACTION FROM THE POPULATION (LATE 1920S - EARLY 1930S)
Authors:   National Academy of Security Service of Ukraine, Liaskovska S.
Published: February 2025

Abstract: The purpose of this research is to highlight the activities of the Ukrainian Red Cross in claim cases, its interaction with international organizations and the authorities of the GPU of the Ukrainian SSR, as well as the utilization by the Soviet political regime of this humanitarian aspect of its work as one of the sources of foreign currency accumulation. The research methodology is based on the principles of objectivity, systematicity, dialectics, and historicism. The study relies on historical methods: problem-chronological, institutional, and historical anthropology (comprehension of motives, aspirations, views, socio-cultural behavior stereotypes of people who applied to the Ukrainian Red Cross for assistance, their reaction to influences from punitive authorities).
Scientific novelty: Based on previously unpublished archival materials, the methods of activity of the Ukrainian Red Cross in searching for heirs abroad and heirs in the territories of the Ukrainian SSR have been analyzed. Attention is focused on the interaction of the Ukrainian Red Cross with the GPU authorities of the Ukrainian SSR in work on claim cases, as well as on the place of the Ukrainian Red Cross in the economic strategy of the Bolshevik regime regarding the extraction of foreign currency from the population within the framework of its international activities.
Conclusions: From the second half of the 1920s, the Ukrainian Red Cross conducted extensive work to establish lost connections of Soviet citizens with relatives abroad. The Ukrainian Red Cross provided intermediary services in obtaining inheritance from deceased relatives abroad, pensions, and insurance payments from foreign state and private institutions and enterprises, and so on. All this work was under the control of the Russian Red Cross, and abroad, its foreign representations assisted it. At the same time, the state policy of regulating the receipt of foreign currency by Soviet citizens from abroad was aimed primarily at bringing currency funds into the state treasury. Heirs were supposed to receive only a certain, insignificant percentage of payments due to them by law. Various methods of influence by the GPU authorities of the Ukrainian SSR were applied to citizens who refused the services of the Red Cross. Thus, the activity of the Ukrainian Red Cross in claim cases of citizens became another source of currency accumulation by the state.

Authors: Ishchuk M. K. , Ajzyatullin H. A. , Cheremnykh V. A. , Pyatikrestovsky K. P.
Published: February 2025

Introduction. In Russian conditions, the depth of support for floor slabs on walls made of large-format ceramic blocks is accepted to be less than in many European countries in order to reduce heat losses. However, with a small depth of support, the shear stresses in the masonry significantly increase, necessitating the construction of a more reliable support joint.

Aim. To develop a design for the support joint of a floor slab on a wall made of large-format ceramic blocks that ensures its shear strength while minimizing heat loss.

Materials and methods. Experimental verification was conducted on samples in the form of columns made of large-format blocks. Three rows of reinforced brick masonry were placed under a fragment of a reinforced concrete slab. A vertical load was applied to the fragment of the floor slab with eccentricity.

Results. The layers of bricks acted as a distribution pad under the floor slab, leading to an increase in loadbearing capacity by at least 13–27 % while maintaining good thermal performance of the wall.

Conclusions. The calculation of the outer wall’s pier showed the feasibility of constructing buildings with external load-bearing and self-supporting walls made of large-format energy-efficient blocks with a thickness of 38 cm for building heights up to five stories. However, considering the brittle nature of masonry failure, it is advisable to limit the height of such walls to two or three stories

El estudio evaluó la efectividad de la fotografía como herramienta para la conservación de las Islas Galápagos, analizando específicamente el proyecto "Jóvenes fotógrafos de Galápagos" implementado por la Dirección del Parque Nacional Galápagos. El enfoque metodológico adoptado fue cualitativo, empleando técnicas de recolección de información como encuestas, entrevistas y revisión documental. La población de estudio estuvo conformada por jóvenes participantes en el programa de fotografía. Los resultados evidencian que la participación en el proyecto no solo aumentó la sensibilización de los jóvenes hacia la conservación de las islas, sino que también fortaleció sus habilidades en fotografía, permitiéndoles acceder a sitios que normalmente no podrían visitar. Un 96,2% de los participantes afirmó que la experiencia tuvo un impacto positivo en sus vidas, y un 100% consideró que la fotografía es un medio útil para transmitir mensajes de conservación a la comunidad. Además, la implicación de los padres en las actividades del proyecto generó un vínculo positivo con la familia y fomentó una mayor comprensión de la importancia de la conservación. En conclusión, la fotografía se demostró como una herramienta efectiva para involucrar a la comunidad local en la conservación de las Islas Galápagos.

La calidad del agua para actividades humanas está cada vez más comprometida por el crecimiento poblacional, la expansión urbana y los residuos industriales y agrícolas. La cuenca del río Culiacán, en Sinaloa, es clave para la producción agrícola del país, con tierras intensivas que abarcan el 60% de su superficie. Este estudio evalúa la calidad del agua en ocho drenes agrícolas de la cuenca, utilizando 22 parámetros físicos y biológicos registrados por CONAGUA entre 2012 y 2020. Se aplicaron cuatro índices para un diagnóstico integral: índice de contaminación integral (ICI), índice de calidad del agua (ICA), índice de estado trófico (IET) e índice de riesgo ecológico (IRE). Estos se eligieron por su uso en investigaciones previas y programas de monitoreo. También se realizó un análisis de correlación de Pearson para identificar las relaciones entre los parámetros. Los resultados muestran que el agua de los drenes no es apta para consumo humano, aunque puede utilizarse en ganadería y agricultura. Se detectó un alto grado de eutrofización, pero la baja concentración de metales pesados implica un bajo riesgo ecológico. Este análisis proporciona información valiosa para la gestión sostenible del agua en una región agrícola estratégica.
