Проблема бедности семей с детьми в России остается одной из наиболее актуальных и требующих решения. Хотя монетарная поддержка представляет собой важный инструмент борьбы с бедностью, современные механизмы социальных трансфертов оказываются не вполне эффективными. Эксперты считают, что решение данной проблемы возможно за счет адресности выплат, что предполагает тщательный отбор получателей государственной поддержки на основе четких критериев. Однако реализация этого подхода сталкивается с серьезными препятствиями, среди которых ‒ ограниченность существующих теоретико-­методологических наработок и необходимость расширения научного арсенала для более эффективного определения семей, нуждающихся в поддержке. В статье рассмотрен концепт автономности как основы для определения адресности социальной поддержки семей. Показано, что традиционно используемое в социальной политике понятие «благополучие» не позволяет полностью решать проблемы семей, в то время как автономность может служить более точным и эффективным критерием. В ходе эмпирического исследования, реализованного через анкетный опрос семей в Тюменской области и с помощью кластерного анализа, авторы построили типологию семей на основе уровня их автономности. Результаты показали вариативность автономности семей и ее зависимость от множества факторов, в том числе территориальных. Авторы обращают внимание на ключевую роль в обеспечении качества жизни семей региональной политики, на важность адаптации социальной поддержки к специфике каждого региона и необходимость учета индивидуальных особенностей и потребностей семей при формировании и реализации мер поддержки.
Federalism and the Formation of UAE Elites after 1971
Authors: Adrianov Artem 
Published: July 2024

The paper studies the formation of the political elites of the UAE after the country had gained independence in 1971. The author pays special attention to the way federal system influenced this process. On the one hand, it reduced the severity of rivalry between the emirates, and on the other hand, consolidated the political order that existed in 1971 and the process of formation of elites. As centralization processes gained pace in the 1970–1980s, federal authorities gained more influence. However, full-fledged federal elites in the UAE, due to the peculiarities of the government structure, never appeared. It seems that every member of the federal elite is somehow connected to the emirate from which he comes. At the same time, within the federal authorities, especially the Cabinet of Ministers, the influence of Dubai, as well as the northern emirates, began to decline. Abu Dhabi’s role as the richest and most influential emirate continued to grow, giving it the largest representation in the Cabinet. In this regard, the article analyzes the biographies of some minsters from Abu Dhabi that make part of the UAE cabinet, as they are considered to be the most representative members of the so-called federal elites. The influence of tribal origin and close relations with the leadership of the emirate in career growth of particular ministers is assessed.

Background: Pulp capping is one of the treatments for reversible pulpitis and aims to maintain pulp vitality. This treatment requires a material that can protect the pulp with good biocompatibility. The physical and mechanical properties, bio interactivity and bioactivity of pulp capping materials are very important for the formation of reparative dentin. Calcium hydroxide (Ca(OH)2) as the gold standard material in pulp capping treatment also has some disadvantages. Another alternative for pulp capping material is blood clam shell because it contains 98% calcium carbonate (CaCO3), which is a compound with a bone-like structure and can induce pulp cell differentiation. Objective: To investigate and explain the difference in compressive strength between CaCO3 from blood clam shells and Ca(OH)2 as a candidate pulp capping material. Methods: This research is a laboratory experimental study with post test only control group design method. Ca(OH)2 and CaCO3 samples were formed with a mixture of powder and aquadest with 4x6 mm sample size. The samples were dried at room temperature and the compressive strength was measured using a universal testing machine (UTM). Result: There is a significant difference in compressive strength between Ca(OH)2 and CaCO3 blood clam shells in the Mann-Whitney test results (p<0.05). Conclusion: The results of the compressive strength test between the mixture of Ca(OH)2 with aquadest in a ratio of 1:1 are greater than the mixture of CaCO3 blood clam shells with aquadest in a ratio of 3:1 so that pure CaCO3 blood clam shells with distilled water without other additives cannot be used as a candidate for capping pulp material.

Published: July 2024

Background: Nanohybrid composite resins have many advantages, but one disadvantage is their absorbent nature which can lead to discoloration. Phenols and flavonoids in nano propolis cause diffusion and affect the matrix and pigments of nanohybrid composite resins. The accumulation of reduction-oxidation reactions causes new compounds of nanohybrid composite resins to occur so that they have different colors. Objective: The study was conducted to determine the changes in surface color of nanohybrid composite resin after immersion in nano propolis at 5% concentration. Methods: Research experimental laboratory method with pre and post test design was applied to 25 nanohybrid composite resin fruit samples of size (5x5x1.5) mm embedded in bovine incisive, then immersed in 5% nano propolis and 25 ml of distilled water at 37oC for five days. The color change (ΔE) was measured with a DSLR camera and processed with Adobe Lightroom Classic software in CIE L*a*b* format. Results: The anova test on ΔE in the data showed the p-value of sphericity assumed was smaller than 0.05. There is a difference in the average measurement results on the first day to the fifth day in the treatment group. Independent t-test of control and treatment data showed a significant difference in measurement results. The results of the post hoc test with the Tukey method showed that the treatment groups at 4x24 hours and 5x24 hours did not have significant differences. P-value at 4x24 hours and 5x24 hours was 0.957. Conclusion: There was a change in the surface color of the nanohybrid composite resin after being immersed in a nano-solution of propolis with a concentration of 5%.
Exploration of Two Different Length Scale Refinement Strategies on the Application of SPH Simulations on 3D Free-surface Flows
Authors: Tran Nam , Roberts Jon , Hastie David 
Published: July 2024

Abstract

A length scale refinement study is a standard practice to ensure the independence of a numerical model on spatial approximations. For smoothed particle hydrodynamics (SPH), the process of length scale refinement study tends to be conducted based on experience. A challenge of defining a universal length scale refinement strategy is the existence of two length scales – particle spacing and smoothing length. Despite the challenge, further investigations of the impact of different refinement strategies should be continually conducted to improve the reliability of practical SPH applications on 3D free-surface flows. In this study, a conventional strategy and a novel coupled refinement strategy are used to investigate the convergence of SPH simulations for free-surface flows using a standard SPH scheme available in an open-source framework. The two case studies are a dam break flow and a lesser-known stable regime water flow inside a rotating drum with lifters. Validations are conducted using existing literature data for the dam break flow and laser Doppler velocimetry (LDV) measurements for the rotating drum flow. The investigation shows that the proposed coupled length scale refinement strategy does not offer a significant improvement for the SPH model of the dam break flow comparing to the conventional strategy. On the other hand, the stable regime rotating drum fluid flow shows that both refinement strategies are not sufficient to tackle SPH’s on-going fundamental challenge of accurately predicting the flow field of complex 3D turbulent flows with free surfaces.
An adaptive variance adjusting strategy for the climatological background error covariance matrix based on deep reinforcement learning

Abstract

Precision in the initial state is pivotal for the prediction accuracy of numerical weather prediction models. A mature method for providing the initial state, variational data assimilation (VarDA) relies notably on a climatological background error covariance matrix, especially its diagonal, which encapsulates variance information. Nevertheless, variance estimation often contains errors, and current adjustment methods are manual or semi-adaptive. In this paper, an innovative adaptive strategy for adjusting variance, based on deep reinforcement learning is proposed. Harnessing the robust data-sensing capabilities of deep learning alongside the adept decision-making skills of reinforcement learning, our strategy aims to optimize assimilation performance by end-to-end learning from sensing VarDA state input to generating a variance-adjusted vector as output. Numerical experiments on the Lorenz96 model demonstrate that the initial state generated by the VarDA system adjusted by our method exhibits almost consistently the lowest climatological root mean square error compared to state-of-the-art methods, regardless of the quality of observations. With the initial state more aligned with the dynamic properties of the forecast model, the prediction capabilities of the experimental forecast model are enhanced to two Lyapunov times and the mean days of available forecast to the model are maximal in a one-month cycle statistic.

Abstract

The blue crab (Callinectes sapidus) is an invasive species that has occurred in the Mediterranean Sea since the mid twentieth century but undergone a significant population increase in the last decade. This worrying increase has raised concerns necessitating to provide information about its ecology and population dynamics at different scales, including its dispersal patterns. Biophysical modeling is a valuable tool for addressing the challenges associated to the study of marine species dispersal across various timeframes and geographical areas. To study the dispersal routes and connectivity of the blue crab in regions of the Mediterranean Sea where this invasive species has been observed, we used a biophysical modeling study, combining a Lagrangian tool with two hydrodynamic models of different spatial resolutions and geographical coverages but with the same period (2010 to 2020). We highlight the main larval dispersal routes, such as the recurrent connections between nearby coastlines including Tunisia and Sicily, as well as Sardinia, Corsica, and the Ligurian Sea coast, and their consistency, both across the entire Mediterranean Sea and a focus on its Northwestern part. The areas with the highest larval retention are revealed to be the Gulf of Lion, the Gulf of Gabès, the Adriatic Sea and the Levantine basin. Furthermore, the critical role of islands in the colonization dynamics of the blue crab is emphasized. Interconnected regions are identified, including Tunisia, Sicily, Sardinia, Corsica, and the coastlines of the Ligurian and Tyrrhenian Seas. Larval connectivity was determined to be high between the Eastern and Western Mediterranean basins, likely explaining the crab's rapid invasion into suitable habitats over the whole sea. In more isolated regions, such as the Adriatic Sea, highest self-recruitment rates were obtained. These findings provide valuable insights for the development of tools and visualizations that can assist managers and stakeholders in gaining a better understanding of the challenges posed by the invasion of the blue crab in the Mediterranean Sea.

Abstract

Triage is of great importance in the procedure of the emergency diagnosis, which needs artificial intelligence to assist due to the scarcity of medical resources. However, AI models for aiding triage have difficulty in identifying levels that are difficult or ambiguous for human clinicians to distinguish. Here, to address this challenge and improve the performance of triage models, we propose KUTS, a foundational classification model for emergency triage, which leverages a knowledge prompt-tuning encoder and an uncertainty-based classifier. KUTS takes tabular data and chief complaints as input, and then generates the recommended triage level for human clinicians. On the most difficult level for human to distinguish (Level 3), our KUTS significantly outperformed the previous shallow single-modal methods, deep single-modal methods and deep multi-modal methods by an average of 14.85%, 28.38% and 11.14%, respectively. Besides, on all the triage levels, our KUTS also outperformed the previous shallow single-modal methods, deep single-modal methods and deep multi-modal methods by an average of 9.02%, 9.45% and 4.18%, respectively. KUTS provides a foundational framework and paradigm for the study of emergency triage, and can be extended to scenarios that require pre-hospital emergency treatment such as disasters and accidents.
Hippo pathway and NLRP3-driven NETosis in macrophages: Mechanisms of viral pneumonia aggravation
Authors: Pan Linghui , Luo Bijun , Wang Xiaoxia , Lin Jinyuan , Mo Jianlan , Xie Jiaan , Zhou Yanqiong , Feng Jifeng 
Published: July 2024

Abstract

Background
Severe viral infections can precipitate acute lung injury, causing substantial morbidity and mortality. NETosis plays a crucial role in defending against pathogens and viruses, but its excessive or dysregulated formation can cause pulmonary damage, with research into its regulation offering potential insights and treatment strategies for viral lung injuries.
Methods
Elevated levels of NETosis were detected in the peripheral blood of patients with viral pneumonia. To explore the correlation between NETosis and virus-induced acute lung injury, we employed a murine model, administering poly(I:C) (polyinosinic-polycytidylic acid), an artificial substitute for double-stranded RNA, intratracheally to mimic viral pneumonia. Assessment of NETosis biomarkers in afflicted patients and poly(I:C)-stimulated mice was conducted, alongside mechanistic investigations into the involvement of the Hippo signaling pathway, inflammatory factors, and chemokines in the injury process. Cytokine assays, co-culture experiments, and downstream inflammatory mediator analyses were used to ascertain the role of the Hippo pathway in macrophage to mediate NETosis.
Results
Enhanced expression of NETosis biomarkers was found both in patients with viral pneumonia and in poly(I:C)-stimulated mice. Hippo pathway activation in conjunction with increased levels of inflammatory actors and chemokines was observed in lung tissues of the mouse model. Elevated IL-1β was detected in cells and macrophages isolated from infected mice; this was mitigated by Hippo pathway inhibitors. IL-1β was confirmed to induce NETosis in co-culture experiments, while NLRP3, functioning downstream of the Hippo pathway, mediated its secretion. Patients with viral pneumonia exhibited increased NLRP3 and IL-1β in monocyte-macrophages relative to healthy controls.
Conclusions
Activated Hippo pathway in macrophages during poly(I:C) exposure upregulates NLRP3 and IL-1β expression to promote the occurrence of NETosis, thereby aggravating virus-induced lung injury. This study identifies a potential target pathway for therapeutic intervention to mitigate lung injury stemming from viral infections.

Abstract

The research investigated on the phytochemical compositions, proximate analysis, and antioxidant properties of ten selected underutilized fruits in Sri Lanka. Despite their potential health benefits, these fruits are often overlooked in favor of more commonly consumed varieties. Hence, this research aims to highlight the nutritional and therapeutic value of these fruits, encouraging their incorporation into the diet and promoting conservation of biodiversity. The presence of phytochemicals; polyphenols, flavonoids, tannins and saponins in different extracts of fruits was qualitatively tested using methanol, water and acetone as solvents. Total phenolic and flavonoid contents were estimated using Folin-Ciocalteu and Aluminium chloride methods, respectively. Antioxidant activity of the fruit extracts was assessed using DPPH assay, ABTS assay and FRAP assay. The vitamin C, fat, protein, carbohydrate, moisture and ash contents of the fruits were also analyzed. The total phenolic contents, flavonoid contents and antioxidant activities of the fruit extracts were different depending upon the type of the solvent used for extraction. Acetone was the most efficient solvent for the extraction of total phenolics, flavonoids and antioxidants of the selected fruits. The highest total phenolic content, flavonoid content and ascorbic acid content were recorded from P. pussilla and S. caryophyllatum. These findings conclude the potential of the 10 selected underutilized fruits and suggest to enhance and promote their commercial value in utilization with better biodiversity conservation strategies.

Abstract

Sediment flocculation and sedimentation is a common phenomenon in estuarine coastal areas, and its sedimentation characteristics are one of the key contents of sediment transport research. In order to realize the purpose of high turbidity sediment flocculation without affecting the water quality, the authors propose a method to promote the flocculation and sedimentation of viscous sand to realize the separation of water and sand - ultrasonic-assisted flocculation and sedimentation method. Flocculation and sedimentation of viscous sand was studied by ultrasonic waves, and the results showed that: (1) when the concentration of sand content was 29 ~ 79%, the rate of flocculation and sedimentation of viscous sand was V natural > V ultrasonic waves + natural, but compared with natural sedimentation, the turbidity of the water quality was significantly reduced by the flocculation and sedimentation of ultrasonic waves and then natural sedimentation; at the same time, due to the pulsating vortex generated by the ultrasonic waves, the algae in the water body and other At the same time, due to the pulsating vortex generated during the ultrasonic action, other impurities in the water body such as algae floated on the water surface, which had the effect of removing algae in the water; (2) when the concentration of sand content was 41%~52%, the ultrasonic action prompted the viscous sand to produce the best flocculation and sedimentation effect, which corresponded to the clear and muddy interface with the settling height of 3.05 ~ 3.45 cm, and the rate of settling was 0.161 ~ 0.173 cm/min; (3) under the action of ultrasonic action, the water content of water W top > W middle > W middle, and then natural settlement after flocculation and sedimentation were achieved at different times. (3) Under the effect of ultrasonic waves, different time corresponds to different layers of wet substrate with water content Wupper > Wmiddle > Wlower, and dry substrate with water content Wupper < Wmiddle < Wlower. The research results can provide research and technical references for the study of flocculation kinetics and the treatment of high turbidity sandy water bodies.
