Aim. Comprehensive assessment of the stability of cross‐border cooperation between the Russian steppe regions of the Urals and Siberia and the Republic of Kazakhstan in the fields of foreign trade and migration. To achieve the goal, a model has been developed to assess the prospects for sustainable cross‐border interaction of the Russian steppe regions of the Urals and Siberia with the Republic of Kazakhstan.The research conducted using the methodology developed made it possible to identify the problems of cross‐border interaction of Russian steppe regions with the Republic of Kazakhstan. Against the background of a decrease in general mobility of the population of the Russian steppe regions, the share of those who left for the Republic of Kazakhstan among the total number of those who left abroad had a positive trend during the period analysed in the vast majority of steppe regions of the Russian Federation. In five of the eight regions considered, the interaction is characterized as "stable" and "steady", "unstable" interaction in the field of migration only in the Altai Territory.The Tyumen Region was the leader in terms of the share in the country's export‐import operations among the steppe regions of the Russian Federation for 2015–2021. In the period under review, foreign trade turnover had a stimulating effect on the economy of the Chelyabinsk region, the Republic of Bashkortostan and the Novosibirsk region. At the same time, the most active foreign trade activity with the Republic of Kazakhstan was observed in the Altai Territory and Omsk and Kurgan regions. Stable cross‐border cooperation in the field of foreign trade with the Republic of Kazakhstan is only in place in the Kurgan region.

Aim. Study and identification of species composition and actual location of birds on the territory of the Kyzyl airport and in the airspace above it throughout the year and assessment of the intensity of the ornithological situation in order to ensure flight safety.

The study of avifauna within the airport area within a radius of 15 km was carried out throughout a calendar year using the method of integrated route accounting and stationary observations on the runway. Statistical processing of the field materials was carried out using the Microsoft Excel program.

In total, a fairly high species diversity was revealed within the airport territory – 76 species in zone I – R =2,5 km and 199 species in zone II – R= 15 km. The population density of birds points was calculated in points, the status of stay, seasonal fluctuations in the number and species diversity of avifauna and the intensity of the ornithological situation were revealed.

Despite the rather high species diversity and significant fluctuations in the number of birds, ornithological intensity in zone II during the year is ‘calm’ and reaches the upper limit of the ‘satisfactory’ level occasionally on certain days of late summer – early autumn. A place of increased concentration of birds within airport area II is an urban landfill. The decision to move the landfill beyond a 50 km radius from the runway, the prevention of nesting of aircraft‐dangerous bird species within zone II and the use of visual repellents will allow maintenance of a low level of ornithological intensity throughout the year.
Supporting STEM Success: Digital Curriculum Innovations to Foster Student Retention
Authors: Kehinde Bamigboye
Published: October 2024

STEM (Science, Technology, Engineering, and Mathematics) education is fundamental to cultivating the skills needed in today’s technologically driven world. However, STEM programs face significant challenges with student retention, particularly due to rigorous coursework, lack of support, and insufficient engagement strategies. This paper examines the role of digital curriculum innovations—such as virtual labs, adaptive learning systems, gamification, and AI-driven tutoring—in improving retention rates in STEM education. By analyzing recent studies, case examples, and student feedback, the paper reveals that these digital tools can address key retention barriers by personalizing learning experiences, enhancing engagement, and providing flexible access to educational resources. This study offers actionable insights for educators, policy makers, and institutions seeking to support student success and foster a sustainable STEM workforce through technology-enhanced curricula.
Affective Experiences of Older Adults Enrolled in a Multi-Component Health Promotion Program: A Focus-Group Study
Authors: Taylor Jennifer , Piatt Jennifer A. , Crandall K. Jason , Ramos William D. , Eldridge Lori Ann
Published: October 2024

The purpose of this qualitative study using focus groups was to explore the affective experiences of older adults enrolled in Bingocize®, a health promotion program that combines bingo and exercise after program facilitators received a supplemental training developed by a recreational therapist titled, FUNctional Movement. The training emphasized participant enjoyment and autonomy support utilizing The Self-Determination Enjoyment Enhancement Service Delivery Model. Focus groups, comprised of 17 participants across three sessions, revealed that while the supplemental training may have improved engagement, many were unaware of the fall prevention components of Bingocize®. Focus group themes included autonomy support, enjoyment, future desired activities, and barriers to physical activity. This may highlight a need to explicitly incorporate fall prevention and functional movement into Bingocize® training for facilitators. Additionally, integrating health education topics like sexual health and incontinence into Bingocize® could address participant needs and enhance program offerings. These findings may provide insights for refining Bingocize® training, aligning it more closely with participant expectations through a recreational therapy approach to physical activity in long-term care settings. The authors provide practice recommendations.
Exploring Parent Perspectives on Autonomy Supportive Environments: A Qualitative Recreational Therapy Approach
Authors: Barmoh Alexis , Hill Eddie , Haegele Justin
Published: October 2024

The purpose of this study was to explore the ways parents provide autonomy supportive environments to their child with type 1 diabetes. Self-determination theory (SDT) is focused on interplay between extrinsic forces acting on persons and the intrinsic motive and needs of human beings. This study adopted SDT as its theoretical framework, with emphasis on autonomy supportive environments. Interview questions were formulated and prepared according to components within the SDT. Between January 2023 and March 2023, seven parents consented and participated in interviews via Zoom. Interviews followed a pre-constructed interview protocol which included 10 questions centered on the fostering of competence, relatedness, autonomy, choice provision, rational provision, perspective taking, and advocacy. While it is known that parenting children with type 1 diabetes poses many challenges, our findings support giving a child autonomy to lead to more effective diabetes management. Also, findings indicated the importance of involvement in social groups, such as parent groups and medical specialty camps. Recreational therapist (RT) professionals can measure outcomes as well as additional insight into parent perspective through camp involvement. This further supports RT using the self-determination theory within the practice of diabetes camps to improve health. Authors provide suggestions for future studies and practice implications for parental camp involvement.
How Recreational Therapists with a Disability Perceive Their Current Workplace: Perception of Climate of Inclusion, Self-Advocacy, and Occupational Self-Efficacy
Authors: Zahl Melissa L. , Allen Aubrey , Nelson Rhonda , Wong Bob
Published: October 2024

High perceived levels of climate of inclusion, occupational self-efficacy, and self-advocacy skills in employees are beneficial to employers. Yet, it is unclear how recreational therapists with disabilities perceive their workplace's climate of inclusion as well as their own self-advocacy skills and occupational self-efficacy. Therefore, the purpose of this study was two-fold: (a) to investigate the extent to which Certified Therapeutic Recreation Specialists (CTRSs) with a disabling condition perceive climate of inclusion, self-advocacy, and occupational self-advocacy in their current workplace; and (b) to explore if there are associations between climate of inclusion, self-advocacy, and occupational self-efficacy in the workplace. A convenience sample of 77 CTRSs who identified as having a disability participated in this study. Results indicated that participants were neutral regarding the climate of inclusion at their current workplaces, are confident with their self-advocacy skills at work, and perceive their occupational self-efficacy levels to be fairly high. There are also positive associations between the three concepts of climate of inclusion, self-advocacy, and occupational self-efficacy. Future research is needed to better understand the neutrality recreational therapists with disabilities perceive of their workplace as well as to conduct more robust studies.
Determining food intake, the requirement, and weighing the relative risk between food secure and insecure households in rural areas of Ethiopia: The case of West Hararghe zone

Published: October 2024

The severity of food insecurity in Ethiopia is among the worst globally, with record-breaking food assistance needs by various factors. This study tries to uncover various aspects of food security related to food availability, food access, food utilization and food stability dimensions of food security. The study was executed in the west Hararghe zone of the Oromia region of Ethiopia. Its main objective was to determine the food security status of households, with specific objectives aiming at computing individual daily kilo calorie intake, determining the average food requirement, comparing the relative risk between food secure and insecure households and identifying factors that affect household food security status. A multi-stage sampling procedure, involving the purposive selection of; the Zone and Woreda, and a simple random selection of households, to draw the required number of representative sample respondents, was adopted. Hence, from 4163 total households, 134 were selected for collecting primary data. Data were analyzed using descriptive statistics, relative risk analysis using Cohorts and independent tests using ANOVA. Food security status was measured using the Household Food Balance Model (HFBM). Using this model, the study obtained 1973 kilo calories per individual per day intake and 2108 kilo calorie as their requirement, which indicated households were energy deficient by 135 kilo calorie with 2-sided-value < 0.1 critical level (t= -1.747, df =133 & sig2-sided. 0.083). Independent test results showed that farm income (at p-value < 0.1), gross product (at p-value < 0.05), age of household head (at p-value < 0.1), years of owning land (at p < 0.1) and family size (at p-value < 0.1) contributed significantly to food security status. Cross-tabulation showed a linear relationship between food security and higher education level (at p-value < 0.05), which urges a concern in improving farming societies’ literacy to the desired level. In the study areas, about 91.8% of the population produces crops depending on the seasonal rainfall and their daily kilo calorie consumed depends on it; this is statistically correlated with the food insecurity problem at p-value < 0.1 critical level (lambada = 1.75 & sig. = 0.08). Therefore, to tackle the food insecurity problem, alternative method of crop production should be devised such as the establishment of irrigation schemes, water harvesting structures, and water conservation practices, among others. Key words: food security, calorie requirement, food availability, relative risk
Twenty-five years of the United Nations General Comment number 12 on the human right to adequate food – malnutrition continues to surge
Authors:   Kyambogo University, Rukundo Peter , Oniang'o Ruth ,   African Journal of Food, Agriculture, Nutrition and Development
Published: October 2024

The human right to adequate food is one of the most fundamental human rights crucial for the sustenance of the planet, and the prosperity of all people. It is firmly established in international human rights instruments and is clarified in the United Nations’ General Comment 12 (GC 12). However, deep vulnerabilities and deprivation of the right to adequate food in the form of hunger, food insecurity and malnutrition have persisted in many parts of the world. The climate-induced disasters also continues to devastate many communities, thereby depriving them of their rights including adequate food. This commentary provides a broader perspective on the 25 years of the GC 12 to stimulate further debate and actions to entrench human rights, especially the right to adequate food, at the centre of the food systems transformation and overall sustainable development agenda. This year 2024, marks 25 years of the Global Compact 12 on the human right to adequate food. While it is an important opportunity to celebrate this great achievement of engraining this right into the wider sphere of global reference at the United Nations level, the domestication in countries into actions that concretely address the problem of hunger and malnutrition has been slow in many countries. The world is now faced with the grim realities of starving populations arising from unnecessary and unjust wars, and food continues to be used as a weapon of war against international law and human imagination. Worse still, in the current environment of climate change and its adverse effects on food systems, SDG2 (Zero hunger by 2030), seems unrealistic. Finally, it is no longer a question of providing carbohydrates, as the need to address quality, safety, nutrition and cultural acceptability is ever so pressing. Going forward, there is a need to accelerate advocacy efforts, research and policy formulation that fully operationalise GC 12 in country-level food systems and nutrition interventions. Realization of the right to adequate food benchmarks in GC 12 should certainly be the penultimate of such interventions as strategic food reserves, poverty and hunger reduction programmes, humanitarian disaster preparedness, contingency funding, social protection and child care among others.

Rôle du forestier sahélien
Authors: Ferlin Guy R.
Published: October 2024

Dans les zones sahéliennes, les forestiers ont généralement essayé de délimiter et de préserver un « domaine forestier », comme ils le faisaient dans les zones forestières. L'auteur estime qu'il s'agit là d'une conception erronée ; les principaux produits des savanes sahéliennes sont des produits d'élevage et non des produits ligneux. La première nécessité est donc d'organiser une exploitation rationnelle de la végétation au profit des troupeaux, en liaison avec le développement forestier.L'auteur insiste sur la nécessité de cet aménagement sylvopastoral et évoque deux autres tâches du forestier sahélien : la sylviculture des peuplements naturels et celle des plantations d'arbres.
Orna face analysis
Authors: Lopes Amanda , Germani Marcelo , Granjeiro José Mauro
Published: October 2024

Aim: Facial aesthetics is a dynamic field requiring precise professional assessment, considering beauty concepts, variability in cultural and ethnic facial features, and patient perception. This study aimed to develop the Orna Face Analysis (OFA), an integrated tool for detailed facial evaluation to improve the planning of aesthetic treatments. Methods: The OFA integrates multiple analysis methods, considering key aspects such as youthfulness, average appearance, symmetry, and dimorphic features to create a comprehensive evaluation protocol based on a critical review of the scientific literature searched through PubMed, Scielo, Web of Science, and Scopus databases without language or time restrictions. Results: The OFA was designed as an electronic form that can generate a printed file, allowing for a deep understanding of patients faces by highlighting these essential aspects. This approach enables detailed and personalized diagnostics essential for effectively planning facial aesthetic treatments and meeting patient expectations. The OFA emerges as a complementary and integrative tool in facial aesthetics, promoting a personalized and evidence-based approach to facial harmonization. After constructing the OFA prototype in electronic and printed formats, the tool was tested in a clinical setting (TRL 6 – technology readiness level) to assess its objectivity, clarity, coherence, precision, and usability. TRL 6 indicates that the system has been demonstrated in a relevant environment but requires further testing for full validation. Conclusion: A preliminary evaluation by a facial harmonization specialist confirmed that the OFA enables the creation of highly personalized treatment plans, accurately reflecting a range of aesthetic outcomes. Further validation will solidify its applicability across diverse patient populations and settings.

Published: October 2024

In this research, it was intended to find out the frequency of cyber bullying and cyber victimization experienced by students who are attending different schools in a city center and to investigate the relationship between these situations and anxiety and risk of depression. The research population consisted of 460 students studying at Anatolian High School, Private High School, and Imam Hatip High School. This cross-sectional, analytical study included 9th, 10th, 11th and 12th grade voluntary students. Data collected via questionnaire consisted of three parts: socio-demographic information form, the cyber bullying scale (CBS) and the hospital anxiety and depression scale (HADS). The daily internet usage time of the participants were found to be 4.07±3.77 hours. Fifty-eight point seven percent (n=270) of the students were victims while 24.5% (n=112) of them were both bully and victims. The cyber victimization score of male students was found to be 24.1±9.6. The mean anxiety and depression scores of the students were 9.6 ± 4.3 and 7.2 ±3.9 respectively, and difference was significant between cyber victims and those who are neither bully nor victims (p<0.001). Anxiety and depression risk were positively correlated to cyber victimization score. The results of this study reveal that cyber bullying and victimization in young people are quite high. The relationship between cyber bullying, cyber victimization and anxiety and depression poses a significant threat for adolescents.
Varicose vein disease in the context of insulin resistance
Authors: Korolenya Valeria , Filipenko Maxim , Smetanina Mariya
Published: October 2024

The prevalence of insulin resistance (IR) is growing every year, which determines the risks of developing type 2 diabetes and cardiovascular diseases. Currently, IR is not recognized as a risk factor for the development of varicose veins (VVs), but the connection between the two is tacitly obvious because obesity and diabetes are risk factors for VVs. In this review, we have attempted to highlight the common nature of these two conditions in the context of mitochondrial dysfunction, inflammation, endothelial dysfunction, and tissue hypertrophy, and spotlight the role of IR in the development of VVs. We conclude that IR can contribute to the appearance of VVs.
Robin’s Criterion on Divisibility (II)
Authors: Vega Frank
Published: October 2024

Robin's criterion states that the Riemann hypothesis is true if and only if the inequality $\sigma(n) < e^{\gamma } \cdot n \cdot \log \log n$ holds for all natural numbers $n > 5040$, where $\sigma(n)$ is the sum-of-divisors function of $n$ and $\gamma \approx 0.57721$ is the Euler-Mascheroni constant. The possible smallest counterexample $n > 5040$ of the Robin inequality implies that $(N_{m})^{Y_{m}} > n$, $(\log q_{m}) \cdot \left(1 + \frac{1}{\log^{2}(q_{m})}\right) > \log \log n$ and $\left(1 + \frac{0.2}{\log^{3}(q_{m})}\right) > \frac{\log \log N_{m}}{\log q_{m}}$, where $N_{m} = \prod_{i = 1}^{m} q_{i}$ is the primorial number of order $m$, $q_{m}$ is the largest prime divisor of $n$ and $Y_{m} = \frac{e^{\frac{0.2}{\log^{2}(q_{m})}}}{\left(1 - \frac{1}{\log^{3}(q_{m})}\right)}$. By combining these results, we present a proof of the Riemann hypothesis. This work is an expansion and refinement of the article "Robin's criterion on divisibility", published in The Ramanujan Journal.

Authors: Salazar-Montoya Omar , Idárraga-Arcila Verónica , Torres-Martínez Paula , Duarte-Correa Yudy
Published: October 2024

The increasing demand for fresh and convenient foods has led to the production of Minimally Processed Products (MPP), making them more suitable for culinary and industrial uses. However, cutting potatoes can trigger browning, negatively impacting their sensory and nutritional quality. This study aimed to evaluate different anti-browning methods on Colombian potato varieties (Diacol Capiro, Pastusa, Nevada, and Sabanera) as raw materials for the development of MPP. The physicochemical properties evaluated included moisture, pH, acidity, enzymatic activity, total phenolic content, vitamin C, and browning index. The anti-browning treatments involved immersing the potatoes in citric acid (1%), ascorbic acid (1%), and garlic extract (0.5%). Evaluations were carried out over a 15-day storage period at refrigerated conditions. The results indicated that the Sabanera variety had the highest browning index, followed by Nevada, while Diacol Capiro and Pastusa showed lower browning indices even without the use of technological coadjuvants. Among the treatments, citric acid proved to be the most effective across all varieties, with Diacol Capiro exhibiting the least browning after 15 days. Garlic extract was the least effective against browning. Sensory analysis indicated that the acidic descriptor was noted for both treated (with citric acid) and untreated (control) Diacol Capiro potatoes at similar intensities, suggesting that citric acid did not negatively affect sensory quality and/or was masked during cooking, enhancing overall quality. In conclusion, the Diacol Capiro variety treated with 1% citric acid is the most appropriate choice for use as raw material for MPP without compromising sensory quality.

Authors: Wang Fanglong , Hussain Norhuzailin , Abdul Aziz Faziawati
Published: October 2024

Aging is a common global challenge. The World Health Organization has released the guide “Global Age-Friendly Cities: An equitable, inclusive and sustainable place” in which it is stated that age-friendly recreational landscapes are one of the important elements for cities and communities to create suitable leisure and social activities for older people. As a healthy green living room at the doorstep, residential green space is of great significance for building age-friendly recreational landscapes in residential green spaces. In this paper, based on the perspective of the demand of older adults for residential green space recreational landscapes, we use the systematic literature review method to comprehensively and deeply comb and summarize the existing research results and put forward China’s future key research directions in this field in a comparative analysis. The study found that: 1. The research heat in this direction has been high in the past five years, and the amount of literature in China and the United States is the highest. 2. The main disciplines involved in the study are landscape architecture, public health, and sociology, and the amount of literature in the direction of public health in international journals is the most, and the papers in the direction of landscape architecture in China are the most. 3. The main research methods used are quantitative research, which accounts for 58% of the literature, and questionnaire surveys, which account for 51% of the literature. 4. The main independent variables involved are green space area, walking environment, recreational and health facilities, community participation, etc., and the main dependent variables are satisfaction, frequency of green space use, physical and mental health, community cohesion, and sense of well-being. 5. The five main theories involved are demand theory, ecology theory, health promotion theory, environmental psychology, and environmental gerontology theory. International literature is mostly studied from health promotion theory and ecological theory, and Chinese literature is mostly studied from the perspective of need theory. 6. Measurement indexes are different in diverse disciplines, among which the direction of landscape architecture mainly explores the influence of green space safety, accessibility, multi-functionality, environmental aesthetics, and recreational facilities on the satisfaction, and happiness of older adults from the perspective of green space planning and design. In the direction of public health, the impact of green space on the physical, psychological, and social health of older adults is mainly explored from the perspectives of green space areas, neighborhood environments, and community participation.
Study on the Electric Field Distribution Characteristics of 66kV Dry-type Transformer Based on Functional Graded Material (FGM) Treatment

Published: October 2024

Functional graded materials (FGMs) have been successfully applied in improving the insulation performance of insulators, yet there is currently no relevant literature on their application in dry-type transformers. Therefore, it is meaningful to study on the feasibility of using FGMs to improve the insulation performance of dry-type transformers through research on electric field distribution. This paper sets FGMs in the dry-type transformer spacer only or both spacer and winding end to change the relative permittivity values in the corresponding areas. By comparing the electric field distribution characteristics on the inner and outer surfaces of the high-voltage coil and the lower surface of the spacer of the dry-type transformer under each control method with the case without setting FGMs, the study found that when FGMs were only set on the spacer, the control methods set in this paper could not improve the electric field distribution of the transformer. When FGMs are employed at the spacers and end windings, two modulation strategies can mitigate the electric field intensity on the outer surface of high-voltage windings. Specifically, a continuous increase in relative permittivity can reduce the electric field intensity by 34.02%, while an initial decrease followed by an increase can result in a reduction of 13.58%. This paper provides theoretical guidance for insulation design of transformers with high voltage levels of 66 kV and above, especially as transformers with high voltage levels face greater challenges in regulating surface electric fields.
Requirements Elicitation from Multiple Sources: Case Studies
Authors: Messaoudi Mohammed
Published: October 2024

Requirements elicitation from multiple human sources involves information validation and conflicts resolution to deal with uncertainty inherent in the process. Most requirements analysis methods focus on expressing the requirements and ignore the uncertainty inherent in the process of requirements elicitation. This paper build on the work presented by the author in [1,10], where a method for requirements elicitation from multiple sources was presented. This paper gives an overview of the method and presents detailed case studies. The cases studies were designed to illustrate different aspects of the Source Control Method and to determine its feasibility and its practical utility as a problem investigation and information validation technique

Authors: Chen Hsing-Chih , Lee Chun-Hung , Seekings Timothy Bernd Wallace , Nguyen Linh Bao
Published: October 2024

Renewable energy (RE) is one of the keys to achieving the global goal of net-zero carbon emissions by 2050. Understanding the factors influencing public participation behavior and social acceptance in RE management (REM) is thus essential to a sustainable energy transition embraced by communities and stakeholders. This study aims to assess nine indicators in REM across three dimensions of social acceptance through the public lens, employing an importance–performance analysis. Our findings reveal a significant gap between the perceived importance and performance of various REM components, suggesting dissatisfaction among respondents. Furthermore, the highest priority for improvement was given to the following strategies: "strengthening communication with residents”, "reducing air pollution emissions from power plants", "establishing supervision and management mechanisms", and "building smart grid and power storage equipment" to ensure successful implementation of REM policies. We also found that respondents who were under 50 years of age, lived in Northern Taiwan, had a higher monthly income, and had a better awareness of social acceptance were more likely to participate in the energy transition. The insights gained from this study outline policy implications for improving the public’s social acceptance and advancing the development of RE in Taiwan, contributing to the world’s carbon-neutral mission.
The Shrinking Fermi Liquid Scenario for Cuprates Under the Scrutiny of Optical Conductivity Measurements
Authors: Caprara Sergio , Di Castro Carlo , Mirarchi Giovanni , Seibold Götz , Grilli Marco
Published: October 2024

In a recent paper [B. Michon et al., Nat. Commun. (2023) 14:3033] optical conductivity experiments in cuprate superconductors were shown to display scaling properties consistent with the Marginal Fermi Liquid theory. Here we argue, that the temperature regime studied in these experiments does not allow to distinguish between Marginal Fermi Liquid and a Shrinking Fermi Liquid. In the latter scenario, which we recently proposed and which applies near a quantum critical point, dynamical fluctuations of the order parameter with short correlation length mediate a nearly isotropic scattering among the quasiparticles over the entire Fermi surface leading to strange-metal behavior. If the damping of these nearly local fluctuations increases by decreasing the temperature, the Fermi liquid regime shrinks and the strange-metal behavior is extended to the lowest temperatures. This Shrinking Fermi liquid scenario has many similarities and some differences with respect to the Marginal Fermi liquid theory. In particular, we show that the approximate scaling properties of the optical conductivity in some high-frequency regime predicted by the Shrinking Fermi liquid scenario account to a very good extend for the experimental data.

Published: October 2024

Poverty elimination is an essential and unavoidable step in human development. Predicting poverty is the first crucial step in addressing this issue, especially in developing countries where it remains a significant concern. The main objectives of this paper are: (i) to explore and analyze the multidimensional poverty data in Pattani province, and (ii) to apply feature selection techniques (Chi-Square, Mutual Information, and Gini Index) to enhance the prediction process. These techniques help in reducing irrelevant and redundant features, leading to more efficient models and better insights. This paper presents the development of a predictive model aimed at classifying poverty and providing actionable recommendations for policymakers. Machine learning models, including Decision Tree (DT), Random Forest (RF), and Support Vector Machine (SVM), were employed to assess the impact of feature selection methods on model performance. The effectiveness of each model was evaluated through various metrics, including accuracy. The experimental results show that the success of these models in predicting poverty, with DT, RF, and SVM obtaining 93%, 95%, 94% of accuracy, respectively. The findings underline the importance of feature selection in improving the performance of machine learning models.
DFT Investigation of the Mechanism of Methoxycarbonylation of Styrene by Palladium Chloride
Authors: Patra Shanti Gopal , Saha Aritra , Chattaraj Pratim Kumar
Published: October 2024

The alkoxycarbonylation of styrene by palladium chloride is studied employing the density functional theory (DFT). Initially, [PdCl3]– reacts with methanol to form the methoxy-bound intermediate, which undergoes β-hydride elimination to form the key intermediate [PdCl2H]–. Then, a 1,2-insertion reaction to styrene takes place to form linear and branched alkyl coordinated with the PdII. Then CO coordination followed by a 1,1-insertion reaction leads to the formation of acyl intermediate. Next, the methanolysis leads to the formation of esters. Previous reports with other catalysts suggested the intermolecular/intramolecular transition state (TS) formation with a high activation barrier, and this step was the bottleneck. To the best of our knowledge, it is the first time we have considered a two-step mechanism for the alcoholysis of the ester formation mechanism. After coordination with the metal, the methanol undergoes oxidative addition to form the PdIV square pyramidal intermediate, followed by reductive elimination to form the ester with regeneration of the metal hydride active intermediate. Deeper insight into the nature of bonding at the TSs are obtained through energy decomposition with natural orbital for chemical valence (EDA-NOCV) and quantum theory of atoms in molecules (QTAIM).
A Comparative Study of Swarm-Optimized Machine Learning Models for Diabetic Kidney Disease Prediction
Authors: VENKATESAN DHARINI SHREE , G Saideepika , S Sarathambekai
Published: October 2024

Diabetic kidney disease (DKD) is regarded as a silent assassin due to its delayed signs. It is a progressive illness that can appear in various ways, from mild to severe. The severity of DKD must be determined in order to make educated treatment decisions and understand the hazards that the patient may encounter. DKD is one of the primary causes for death and morbidity among noncommunicable illnesses, affecting 10% to 15% of the global population. Timely prediction of DKD is expected to improve patients' health and reduce mortality. This study aims to predict DKD using machine learning models like Decision Trees, Random Forest, Logistic Regression, Bagging Tree Model and Support Vector Machine, to help in timely detection and cure of this deadly disease. Clinical data required for model training were taken from Kaggle's public repository and additional samples of 50 individuals were collected from local hospital, Coimbatore, Tamil Nadu. Meta-heuristic algorithms based on Swarm Intelligence, such as Particle Swarm Optimization, Ant Colony Optimization, and Firefly Optimization, were employed to optimize the selected models. The main aim of this study is to compare the predictions of different models and identify models that best agree with the given scenario.

In a sports hall, three different groups of young adults played the "bluegill game" (a Prisoner's Dilemma-like sports game). The present study's objective was to measure the extent of cooperative behaviour in a group of 25 team sports players. To maximise gains, a player had to adopt selfish tactics half the time. The group of team sports players came closest to this mixed-strategy Nash equilibrium (chi2=4.07 in a logistic regression, p<0.05). The two control groups (23 individual sports players and 24 non-sportspeople) were found to be significantly more cooperative. The altruistic players kept the game alive while working towards their own defeat. We discuss how the "bluegill game" model can be broadened to other social situations. In these non-collaborative, non-zero-sum games, cooperation is an irrational choice on the individual level but is essential on the group level.

Introduction: Based on clinical practice guidelines, the application of corticosteroids as first-line therapy is common. Although SSHL's etiology is primarily idiopathic, hearing loss can result from perilymphatic fistula (PLF). Recent findings show evidence of a spe-cific rate of PLF based on a cochlin- tomoprotein (CTP) detection test. Based on this rate of PLF treatment, the concepts of SSNHL need to be re-evaluated. The present study aimed to evaluate CTP in SSNHL patients and compare pre-surgical and post-surgical pure tone hearing thresholds after round and oval window sealing as first-line treatment.
Material and Methods: 30 patients with unilateral SSNHL with pure tone average (PTA) (4 Freq.) of 60 dB or more were enrolled in a prospective study. All patients underwent tympanoscopy for middle ear exploration as first-line treatment. After intraoperative obser-vation of possible PLF all patients obtained middle ear lavage to gain CTP samples for following ELISA-based CTP detection tests. All patients received round window and oval window sealing with fascia. PTA hearing thresholds were analyzed post-surgical 3 weeks after treatment based on 4-frequency bone conduction (BC).
Results: Average preoperative pure-tone BC threshold was 97,7 dB compared with 69 dB postoperative BC threshold. Mean BC improved by 20,3 dB after middle ear explora-tion and window sealing. 56% (17 of 30) of patients recovered at least 10 dB. Middle ear cochlin-tomoprotein detection rate was in 70% positive.
Conclusion: The combination of early tympanoscopy and inner ear-specific cochlin-tomoprotein as a detection tool for suspected perilymphatic fistula shows evidence of PLF as a key causative in SSNHL.

Cerebral palsy is a group of nonprogressive conditions that affect movement and posture caused by damage to the central nervous system at an early stage of a child's development. Among this group of patients, there is a higher risk of the appearance and progression of neurogenic scoliosis, which unlike idiopathic scoliosis, progresses after skeletal maturity. The aim of the study was to analyze the association of comorbid factors with the risk of development and progression of neurogenic scoliosis. The study included 133 patients with cerebral palsy. The relationship between comorbidities in children with cerebral palsy and the risk of developing neurogenic scoliosis was demonstrated and proven.

This paper presents an educational application called AR Firework designed for an interactive science museum exhibition in the wild. We adopted STEAM and a game-based education approach for the major visitors and children to teach them the mechanisms of fireworks. Augmented reality is used to simulate dangerous laboratory environments and visualize abstract concepts. DIY souvenirs featuring fireworks are created in the process of interacting with the exhibits. This hybrid souvenir combines a physical firework launcher and AR models. The visitors can present it as a gift to others or display it in the digital gallery. This souvenir establishes a long-lasting connection between visitors and their personal visiting experiences through digital media. This paper promotes an improved understanding of personalization, socialization, AR, and STEAM education. It can be an inspiration for souvenir designers and education products.

Objectives: The aim of the present preclinical study, using rabbits as an experimental model, investigated the effects of a new implant design that incorporates specific changes in the cervical portion, using a conventional implant design as a control group. Materials and Methods: Ten rabbits and 40 dental implants with two different macrogeometries were used. Two groups were formed (n = 20 per group): Collo group, where implants with a new cervical design were used, which present a concavity (reduction in diameter) in the first 3.5 mm and with this portion of the implant without surface treatment; Control group, where conical implants with conventional design were used, which feature surface treatment throughout the body. All implants present dimensions of 4 mm in diameter and 10 mm in length. The initial implant stability quotient (ISQ) was measured immediately after the implant insertion (T1) and immediately after removing the pieces with the implants. The animals (n=5 animals/time) were euthanized at 3 weeks (T1) and 4 weeks (T2). Histological sections were prepared and, the percentage of bone-implant contact (BIC%) and the tissue area fraction occupancy (TAFO%) were analyzed in the pre-determined cervical area of the first 4 mm from the implant platform. Results: The ISQ values showed no statistical differences in T1 and T2 (p = 0.9458 and p = 0.1103, respectively). However, in T3 superior values were found for the Collo group (p = 0.0475). Higher BIC% values were presented in samples from the Collo group compared to the Control group, with statistical differences (3-weeks p = 0.0009 and 4-weeks p = 0.0007). TAFO% (new bone, medullary spaces, and collagen matrix) had statistical differences between the groups at each evaluation time. Conclusion: Within the limitations of the present pre-clinical study, the results of this study suggest that the new implant design with changes in the cervical portion (Collo group) presents significant advantages concerning the conventional implant (Control group), regarding stability in the initial times and osseointegration.
Investigating the impact of Spatio-Temporal Variations of Water Column Optical Properties on Satellite-Derived Bathymetry Estimates in the Eastern Mediterranean

Bathymetric data is crucial for benthic monitoring in coastal areas but is traditionally obtained through costly and geographically limited acoustic methods. This study uses Satellite-Derived Bathymetry (SDB) in the Eastern Mediterranean, focusing on the Cretan Sea in Greece. It explores how variations in water column optical properties affect SDB models over four years (2019-2022) using Sentinel-2 satellite data. The research covers two areas with contrasting features: Chania Gulf and the open waters around Chrissi Island. Three methodologies were tested: band-ratio, linear-logarithmic, and an inherent optical properties linear model. Significant spatio-temporal variations in SDB models were found due to seasonal changes in water column properties, such as temperature and suspended organic materials. Linear optical properties-based methods performed best, achieving a mean RMSE close to 1 meter, slightly outperforming the ratio-based method. The logarithmic method was less effective, with RMSE values ranging from 1.3 to 1.5 meters. A preliminary Kalman Filter (KF) analysis increased RMSE to the decimeter level. This study demonstrates the impact of water column optical properties on SDB models. It highlights the value of SDB for cost-effective, high-resolution coastal mapping in complex coastlines like those in Greece.
