This research aimed to investigatethe age of embryos of pink and white lotus for in vitropropagation and examine the sensitivity of young lotus plants derived from tissue culture to acute gamma radiation. The seeds of both lotus varieties were 4-week, 6-week and 8-week-old embryos cultivated on solid MS medium. They were then transferred to solid MS medium supplemented with 3 mg/L BA. After culturing, the 6-week-old pink lotus embryos had an average maximum petiole length of 16.78 ± 1.01 cm and an average of 11.84 ± 0.44 roots/explant, while the 6-week-old white lotus embryos had an average maximum petiole length of 15.48 ± 0.68 cm and an average of 11.76 ± 0.70 roots/explant. Each young lotus plant produced one shoot. After treating the young lotus plants with liquid MS medium supplemented with 3 mg/L BA, both lotus varieties showed increased shoot numbers at 3.54 ± 0.13 and 3.40 ± 0.91 shoots/explant. Young lotus plants of both varieties were exposed to gamma radiation levels of 0, 20, 30 and 40 Gy. The LD50 value for pink lotus was 26.138 Gy, while the LD50 value for the white lotus was 32.031 Gy.The LD50 value will offer vital information for determining the optimal dosage of gamma radiation for both pink and white lotus in vitro.

Extremophiles are organisms that are capable of living in extreme environments (radiation, temperature, pH, salinity etc). Fascinating questions on the potentialities of extremophiles from hypersaline habitats are yet to be fully answered. Hence, it is an intriguing study that needs continuity. Most recent studies, on extremophiles, reveal the intrinsic benefits of halophiles in many biological and biotechnological processes ranging from several medical applications to a wide variety of industrial processes. In most cases, the applications of these extremophilic microorganisms and their metabolites (e.g. enzymes, inhibitors, compatible solutes, etc) in biotechnology have been the driving force to understanding these organisms, and have contributed immeasurably to several biological types of research. Despite the justifications from several studies on the potentialities of extremophiles, relatively little information is still provided on the biotechnological applications of halophiles, hence the optimal capabilities of these diverse populations of microorganisms remain clandestine and need to be explored. This review is aimed at discussing recent applications of extremophiles from hypersaline environments in order to provide a basis for researchers to explore these halophilic organisms for newer applications in many fields such as in agriculture, pharmaceuticals, medicine, food, and industries.

Supply Chain Integration (SCI) is widely acknowledged as a strategic process that significantly contributes to positioning organizations favorably for improved firm performance. This study delves into the relationship between financial performance and supply chain integration, focusing on the impact of various integration strategies, including internal control, supplier integration, customer integration, and internal integration, on a business's financial performance. Through Regression, Reliability, and Correlation analyses conducted on an 80-respondent survey, correlations between the variables were examined. The findings reveal a substantial and positive influence of SCI on a company's financial success. Further analysis of individual dimensions indicates that customer integration yields the most significant positive effect on financial success. Moreover, notable correlations were observed between supplier integration and financial performance, internal control and financial performance, and internal integration and financial performance. While each variable demonstrates a statistically significant impact, customer integration emerges as the most influential factor. This study underscores the relationship between information flows and financial performance, underscoring the benefits of integration resulting from knowledge development. Supply chain experts can leverage these research findings to enhance their business's bottom line.
Minimal Units of Consciousness and Possible Evolution of Intelligence
Authors: Funk Richard H. W. ,   Institute for Anatomy, Medical Faculty, TU Dresden, 01307 Dresden, Germany
Published: July 2024

The present review attempts to find out what are basic elements of consciousness - that is, what are the characteristics of purposeful perceptions and "reactive" actions observed in living beings. The difference between consciousness and intelligence is also dealt with in this respect. These considerations are based on previous work on feedback loops in "active" matter leading to "living matter". To follow this line, we briefly look at the development of information processing and the formation of neural networks in evolution, culminating in the formation of the human brain. As a synthesis, we deal with current hypotheses of biophysical processes that take place in the human brain in connection with consciousness and intelligence. Furthermore, it discusses basic principles of information processing in artificial intelligence and the difference between human consciousness and intelligence compared to AI. In doing so, we touch on philosophical questions such as the relationship to "minimal physicalism", which is related to teleonomy as a "weak form" of "panpsychism". Thus, the present review can also add some aspects to a lively discussion that has recently erupted on animal consciousness, culminating in the "New York Declaration on Animal Consciousness."

Authors: Battista Daniele
Published: July 2024

The current technological landscape has been profoundly shaped by rapid and significant advances in artificial intelligence (AI), sparking extraordinary interest in academia and beyond. Considered an unprecedented revolutionary technology, it has captured the attention of researchers, scholars, and professionals from various disciplines as it offers transformative prospects in a wide range of fields. This technological progress has sparked a broad debate on its social, ethical, and economic impacts, raising important questions that require in-depth and multidisciplinary investigations. AI thus emerges as an ever-evolving discipline with significant implications for the future of human progress. Besides being seen as an opportunity to pursue common societal goals, many observers have recognized the potential risks associated with such developments. Its integration into the political context also presents a promising opportunity to enhance the efficiency of political decisions however, its adoption raises significant challenges that require careful evaluation. The aim of this research is to explore in detail the relationship between AI and political communication, focusing on the analysis of AI's usage in this context while highlighting the phenomenon of deepfakes, which jeopardize democratic stability and security in many cases. The importance of this research contribution lies in the context where AI is assuming an increasingly prominent role in daily dynamics, making it essential to fully understand the implications and potential consequences of AI application in the political field. Furthermore, it is crucial to assess whether such initiatives can genuinely be considered democratic or if they could represent a dangerous trend towards the use of manipulative algorithms.

Published: July 2024

Defined as the killing of a newborn individual by a conspecific, infanticide by males is widespread in mammals. Results from this paper used genetic analysis to confirm and characterize the first report of non-parental infanticide in giant armadillos. Genetic evidence demonstrates that the killer male is unrelated to the killed infant but is the father of the next offspring. This evidence supports the sexual selection hypothesis, in which infanticide is used to obtain increased access to breeding females.

Authors: Wang Feixiang , Huang Guoxin , Luo Yuqing , Xiong Kaixin , Liu Ying , Wang Yao
Published: July 2024

Background

Malignant lymphoma (ML) is a group of malignant tumors originating from the lymphatic hematopoietic system. Previous studies have found a correlation between circulating immune cells and ML. Nonetheless, the precise influence of circulating immune cells on ML remains uncertain.

Methods

Based on publicly available genetic data, we explored causal associations between 731 immune cell signatures and ML risk. A total of four types of immune signatures, median fluorescence intensities, relative cell, absolute cell, and morphological parameters were included. Primary analysis was performed using inverse variance weighting (IVW) to assess the causal relationship between circulating immune cells and the risk of ML. Sensitivity analysis was conducted using Cochran’s Q test, the Mendelian randomization Egger regression intercept test, and leave-one-out analysis.

Results

ML had a statistically significant effect on immunophenotypes. Twenty-three immunophenotypes were identified to be significantly associated with Hodgkin lymphoma risk through the IVW approach, and the odds ratio values of CD64 on CD14− CD16+ monocyte [2.31, 95% confidence interval (CI) = 1.41–3.79, P1 = 0.001], IgD+ CD24+ B-cell %lymphocyte (2.06, 95% CI = 1.13–3.79, P1 = 0.018), B-cell %lymphocyte (1.94, 95% CI = 1.08–3.50, P1 = 0.027), CD24+ CD27+ B-cell %lymphocyte (1.68, 95% CI = 1.03–2.74, P1 = 0.039), and CD14+ CD16− monocyte %monocyte (1.60, 95% CI = 1.15–2.24, P1 = 0.006) ranked in the top five. Eleven immunophenotypes were identified to be significantly associated with non-Hodgkin lymphoma risk, CD86 on granulocyte (2.35, 95% CI = 1.18–4.69, P1 = 0.015), CD28−CD8+ T-cell absolute count (1.76, 95% CI = 1.03–2.99, P1 = 0.036), CCR2 on myeloid dendritic cell (CD24+ CD27+ B cell, 95% CI = 1.02–1.66, P1 = 0.034), CD3 on effector memory CD8+ T cell (1.29, 95% CI = 1.02–1.64, P1 = 0.012), and natural killer T %lymphocyte (1.28, 95% CI = 1.01–1.62, P1 = 0.046) were ranked in the top five.

Conclusion

This study presents compelling evidence indicating the correlation between circulating immune cells and lymphoma, thus providing guidance for future clinical research.
Research progress on anti-cancer mechanism of salidroside regulating miRNA-mRNA signaling axis
Authors: Wu Xiaoxiong , Zhang Zhendong , Wang Xiaoping
Published: July 2024

MiRNA (MicroRNA) can target and regulate mRNA, thereby influencing the biological processes of tumors. The extract of Tibetan medicine Rhodiola demonstrates anti-tumor effects by targeting and regulating cancer-related signaling molecules and pathways. This review aims to pave the way for integrating salidroside into clinical practice, fully leverage its multi-effective and multi-targeted biological effects, and innovate approaches to tumor prevention and management, thus enhancing cancer prognosis. We initially delve into the occurrence and mechanism of action of miRNA, as well as the anti-tumor mechanism of the miRNA-mRNA signaling axis. Additionally, it was described that salidroside can hinder cancer cell proliferation by inducing autophagy and apoptosis, inhibiting cell metastasis and invasion, and modulating the tumor microenvironment and cell cycle. Moreover, examples from lung cancer, gastric cancer, and nasopharyngeal carcinoma confirm that salidroside regulates the onset and progression of tumors through the miRNA-mRNA signaling axis. This groundbreaking discovery carries significant implications for cancer diagnosis and treatment, offering a novel pathway for therapeutic intervention.
The emerging role of cardiovascular magnetic resonance in the evaluation of cardiac involvement in systemic sclerosis
Authors: Mavrogeni Sophie I. , Pepe Alessia
Published: July 2024

Systemic sclerosis (SSc) is an autoimmune rheumatic disease, characterized by vascular, inflammatory and fibrotic alterations. Cardiac involvement is the « fatal tip of the iceberg» in SSc, as it leads to high morbidity/mortality. Cardiovascular imaging modalities play an important role in the early diagnosis and treatment assessment of cardiac involvement. Echocardiography is the corner stone for evaluation of cardiac involvement, providing information about function, wall motion, pulmonary pressure, pericardium and valvular disease. It is a low-cost modality, widely available, without radiation and with great experience among cardiologists. However, it is a window and operator dependent modality and cannot provide tissue characterization information, absolutely necessary for diagnosis and treatment of cardiac involvement in SSc. Cardiovascular magnetic resonance (CMR) can perform myocardial function and tissue characterization in the same examination without radiation, has excellent reproducibility and is window and operator independent. The great advantage of CMR is the capability to assess peri- myo-vascular inflammation, myocardial ischemia and presence of replacement and diffuse myocardial fibrosis in parallel with ventricular function assessment. The modified Lake Louise criteria including T2, native T1 mapping and extracellular volume fraction (ECV) has been recently used to diagnose inflammatory cardiomyopathy. According to expert recommendations, myocardial inflammation should be considered if at least 2 indices, one T2 and one T1 parameter are positive, whereas native T1 mapping and ECV assess diffuse fibrosis or oedema, even in the absence of late gadolinium enhancement (LGE). Moreover, transmural/subendocardial LGE following the distribution of coronary arteries and diffuse subendocardial fibrosis not related with epicardial coronary arteries are indicative of epicardial and micro-vascular coronary artery disease, respectively. To conclude, CMR can overcome the limitations of echocardiography by identifying acute/active or chronic myocardial inflammation/fibrosis, ischemia and myocardial infarction using classic and parametric indices in parallel with biventricular function assessment
A morphosyntactic haplology of -i drop in the Korean vocatives
Authors: Yim Changguk
Published: July 2024

An intriguing phenomenon in Korean vocative constructions has not received comprehensive attention in the generative literature: in the vocatives, the morpheme -i undergoes drop, and its absence hinges on its immediate adjacency to the vocative marker -(y)a. This article contributes to the literature by demonstrating that this drop is an instance of morphosyntactic haplological dissimilation. Specifically, I identify two ϕ-features, ϕ[−HON: intimate] and ϕ[animate], and propose the morphosyntactic *<ϕ,ϕ> constraint on the -i drop, targeting adjacent matching ϕ-features. This constraint rules out the illicit sequence of *-i-(y)a because both morphemes share matching ϕ-features and their exponents are immediately string-adjacent, resulting in the -i drop. This analysis offers theoretical insights into the mechanisms underlying the haplological dissimilation pertaining to ϕ-features.

Published: July 2024

Introduction. Multiple sclerosis is a chronic disease of the central nervous system, resulting from immune system dysfunction and characterized by demyelination and neurodegeneration. An essential aspect of therapy, besides improving overall quality of life, is also the quality of sexual life of patients with multiple sclerosis.
Aim. The aim of this study was to assess the quality of sexual life of female patients with multiple sclerosis.
Material and Methods. The study was conducted among 100 female patients diagnosed with multiple sclerosis in the Neurology Department. Research tools included a questionnaire regarding patients’ demographic and clinical data, as well as the Sexual Quality of Life Questionnaire — Female (SQoL-F).
Results. The level of sexual quality of life among female patients with multiple sclerosis in the neurology department was associated with the following domains: psychosexual feelings, sexual satisfaction, relationship satisfaction, worthlessness, and sexual repression. 44% of women rated their relationship with their partner as poor. Sexual activity was rated as poor in 43% of cases, and 32% experienced a deterioration in their sexual life before and after the onset of multiple sclerosis. Factors such as demographic characteristics (place of residence, employment status, marital status) and clinical factors (obesity and diabetes) influenced the assessment of sexual quality of life.
Conclusions. The mean score for quality of life in the SQoL-F questionnaire was 69.02 with a standard deviation of SD=25.86 and a median of Me=75. Both socio-demographic and clinical factors influenced the assessment of the level of sexual quality of life among patients with multiple sclerosis. (JNNN 2024;13(1):23–28)

In this work, we made an effort to use dopamine hydrochloride and the solid state method to anchor the gold and silver metallic nanoparticles over the graphene oxide-carbon nanotubes to improve the metal nanoparticles' interaction with the support materials. Because the hybrid nanoarchitectures of graphene-CNT provide enhanced electron transfer ability, which facilitates the catalytic activity more quickly and enhances the rate. Additionally, carbon nanotubes–graphene oxide-metal nanoparticles based hybrid catalyst was developed in a similar fashion. The formation of metallic nanoparticles in a size range of 3–15 nm is visible in the micrographs. These particles developed as nano-islands. The excess reductant formed as polydopamine acts as a stabilizer, and further, we utilise this polydoapmine into carbon by the calcination process. It results that carbonous materials will enhance the interaction between metal and support (CNT/GO). This leads to improved catalytic activity towards the reduction of 4-nitrophenol and catalytic decolorization of methylene blue at room temperature. The suggested technique for synthesizing metal nanoparticles over carbon nanostructures is simple and environmentally friendly.

An excellent fit between the theoretical and experimental studies of the related to structure, optics, and magnetism features of pristine and cerium-modified Zn-O NPs prepared through the wet chemical technique. Refining the XR-D pattern using the Rietveld-method reveals that the samples have a hexagonal Wurtzite structure. Absorption spectra reveal a shrinking bandwidth gap as cerium doping increases, substantiating ce2+ ion's essential function in ZnO's spectral qualities. The narrowing of the bandwidth gap due to the presence of impurity states was also verified by first-principles calculations. The residual magnetization increases with Cerium doping, and magnetic tests show roomtemperature weak-ferromagnetism (RTFM). In addition, ferromagnetism for cerium doping is confirmed by both first-principles calculations and experiments. Theoretical calculations imply that the cerium atoms may agglomerate to generate metallicantiferromagnetic chromium oxide when cerium doping reaches 8%. At ambient temperature, however, ferromagnetic behaviour is feasible since both ferromagnetic and antiferromagnetic behaviour are degraded when cerium is widely disseminated throughout the lattice as revealed by XRD studies

Epistemologia da Ciência Forense e a construção de uma síntese teórica: desdobramentos práticos
Authors: Giovanelli Alexandre
Published: July 2024

A definição da natureza da criminalística e da ciência forense é uma discussão que tem sido retomada com vigor na literatura internacional. No âmago desta discussão está a demarcação de princípios e postulados que caracterizariam a ciência forense como uma ciência autônoma, com métodos próprios. O presente artigo utilizou como base a síntese teórica proposta por Giovanelli [23,24], em que as principais discussões da literatura atual foram consolidadas em seis princípios elencados hierarquicamente e associados a abordagens epistemológicas e metodológicas da ciência forense. Na primeira parte foram discutidos alguns dos pressupostos epistemológicos que fundamentariam a ciência forense, incluindo o seu campo de atuação. Na segunda parte, foram apresentados os desdobramentos práticos e aplicações a partir de metodologia derivada da síntese teórica denominada de “Modelo Sintético da Criminalística”. A partir de seis princípios: Princípio de Locard, Princípio de Kirk, Princípio da Assinatura, Princípio de Bertillon, Princípio da Reconstrução ide Frances Lee e Princípio das Propriedades Emergentes foi estruturado um arcabouço teórico, hierarquicamente organizado e sistemático o qual serve de base para a avaliação crítica do trabalho do cientista forense, incluindo a revisão das metodologias utilizadas, o enfrentamento do viés cognitivo em determinadas fases do trabalho do perito e a ampliação ode possibilidades analíticas. Além disso, o Modelo Sintético da Criminalística proposto permite estruturar um currículo coerente que agregue as competências essenciais para a análise forense. A síntese teórica proposta reforça a ideia de que a ciência forense é uma ciência específica, com seus próprios métodos e princípios.

Authors: So Yeon-Hee
Published: July 2024

This study examines the serial mediating effects of major satisfaction and career adaptability in the relationship between parental career support and occupational engagement among 240 college students. This research employs questionnaire data and serial mediation model analyses via SPSS Macro models 4 and 6 to explore the potential pathways through which parental career support may influence students' occupational engagement. The findings reveal that both major satisfaction and career adaptability serve as significant partial mediators individually (Model 4) and in tandem (Model 6) in the relationship between parental career support and occupational engagement. Furthermore, bootstrapping analysis highlights the indirect effects, showcasing the greater influence of major satisfaction when compared to career adaptability. These findings underscore the importance of incorporating parental career support, major satisfaction, and career adaptability into career education and guidance programs to enhance college students' occupational engagement.
The Effect of Basic Psychological Needs of Mothers with Infants on Parenting Behaviors: The Moderated Mediating Effect of Parenting Stress by Social Support on Social Media
Authors: Oh Mi Ra , Min Ha Yeoung
Published: July 2024

This study focuses on how parenting stress mediates the relationship between basic psychological needs and parenting behaviors in mothers with infants. The study also looks at how social support on social media might moderate this mediated relationship. To empirically verify a moderated mediation pathway, data were collected from 304 mothers of children under 3 years of age through paper questionnaires and online questionnaires and were analyzed using simple regression, multiple regression, process macros model 14 and bootstrapping in IBM SPSS Statistics 22 for Windows. The results are as follows. First, mothers’s parenting stress mediated the relationship between basic psychological needs and parenting behaviors. Second, mothers' parenting stress on parenting behavior was moderated by social support on social media. Parenting stress had a greater negative effect on positive parenting behavior when the level of social support on social media was low rather than high. Third, mothers’ social support on social media positively moderated both paths of this mediated relationship. Depending on the level of social support on social media, the indirect effect of basic psychological needs on parenting behaviors through parenting stress was significant. The findings of this study have important theoretical and practical implications for the use of Internet-based social support when managing basic psychological needs and parenting stress in relation to mothers' positive parenting behavior.

Published: July 2024

Difficulties in comprehending English academic texts encountered by many students lead to the need for improvement in teaching reading. Moreover, in online reading instructions, explicit reading strategies are required so that students can develop their comprehension more independently and become strategic readers. This study aims to find out how explicit reading strategy instructions in online reading classes are implemented and what advantages and challenges are faced during its implementation. This is a case study program evaluation that uses observation, field notes, and interviews. It involves second-year students in an English literature study program taking a reading comprehension course. Despite several limitations, the results reveal that employing explicit reading strategy instructions in the online context can help students enhance their reading skills through structured and systematic phases. This is very much related to the advantage which shows an increase in student motivation in reading that further can improve students' reading ability in general and in comprehending English academic texts. However, these advantages are restricted by technological limits in the online learning process and student motivation variables. To maximize the effectiveness of explicit instruction in the online reading classroom, it is critical to invest in improved technological resources, integrate engaging and interactive content to increase student motivation and provide ongoing professional development for educators. These steps will help to ensure that explicit reading strategy instruction results in the best results possible.

Objective. This paper analyzes the training received by early childhood education teachers during their university studies, as well as their valuation of natural spaces, to determine their qualification to teach environmental education (EE). It also considers the compulsory nature of teaching this subject in early childhood education centers and the general perception of the importance of environmental education as part of sustainable educational awareness. This analysis was conducted among in-service early childhood education teachers in Spain and Costa Rica to establish the differences and similarities in the approach to EE in both education systems. Method. A random and anonymous selection of educators from Spain and Costa Rica was conducted, comprising 199 and 63 participants, respectively. Teachers answered a validated online questionnaire adapted to the purpose of this research. Responses were statistically processed using SPSS and JAMOVI, taking into account possible differences not only between countries but also in aspects such as gender, age, and teaching experience. Results. Despite some significant differences, generally speaking, a globalized perspective of the various issues addressed is shared, emphasizing the need to enhance the initial training of teachers. Conclusions. The differences between countries are not decisive in practice, and many of the problems, shortcomings, and concerns are shared in both countries.

Потенциометрическим методом исследована кислотность NH-групп ряда сульфонамидов и производных глицина в среде диметилсульфоксида. По кривым титрования определены константы диссоциации этих соединений. Показано, что кислотность NH-групп исследованных сульфонамидов контролируется полярным эффектом заместителей. Впервые установлена возможность количественного потенциометрического анализа производных глицина. С помощью программы PASS осуществлен прогноз биологической активности. Установлена взаимосвязь кислотности NH-групп с биологическим потенциалом соединений.

The acidity of NH-groups of a number of sulphonamides and glycinederivatives in a dimethyl sulphoxide medium has been investigated using the potentiometric method. Dissociation constants of these compounds are determined from titration curves. It is shown that the acidity of NH groups in the studied sulphonamides is controlled by the polar effect of substituents. The possibility of quantitative potentiometric analysis of glycine derivatives has been established for the first time. Biological activity has been predicted with the help of PASS software. The correlation of NH group acidity with the biological potential of the compounds has been established.

Бактерии выполняют важные и разнообразные функции в экосистемах крупных рек. В среднем и нижнем течении р. Оби в районах городов и населенных пунктов определяли уровень количественного развития и изучали характер пространственного распределения гетеротрофного бактериопланктона и его размерно-морфологических групп. Вода реки характеризовалась высоким содержанием взвешенных частиц (в среднем (2,22 ± 0,21) × 106 мл-1), к которым была прикреплена значительная часть бактерий: в среднем 41,5 % их общей численности и 35,7 % биомассы. Установлено, что концентрация взвешенных частиц и электропроводность воды находятся среди главных факторов, влияющих на количественное развитие и структуру бактериопланктона. Существенное возрастание его количества, в основном за счет мелких одиночных клеток, зарегистрировано ниже впадения в р. Обь ее крупнейшего притока - Иртыша, и расположенного на его берегах г. Ханты-Мансийска. На этом участке Оби средние значения численности и биомассы бактериопланктона составляли (6,87 ± 4,99) × 106 кл/мл и 142 ± 13 мг С/м3 соответственно, что в 1,6-1,7 раза выше, чем в зонах влияния других городов. Пространственное распределение гетеротрофного бактериопланктона в р. Оби определяется главным образом динамикой водных масс, а также влиянием притоков и городов

Bacteria perform important and diverse functions in the ecosystems of large rivers. The abundance, biomass and spatial distribution of heterotrophic bacterioplankton and its size-morphological groups were studied in the middle and lower reaches of the Ob River in the areas impacted by cities. The river water was characterized by a high content of suspended particles (on average (2.22 ± 0.21) × 106 ml-1), to which a significant part of bacteria was attached: on average, 41.5 % of their total number and 35.7 % of their biomass. The concentration of suspended particles and water conductivity were found to be among the main factors affecting the abundance and structure of bacterioplankton. A significant increase in bacterial abundance, mainly due to small free-living bacteria, was recorded below the mouth of the largest tributary, the Irtysh River, and the city of Khanty-Mansiysk. On this section of the Ob River, the average values of bacterioplankton abundance and biomass were (6.87 ± 4.99) × 106 cells/mL and 142 ± 13 mg C/m3, respectively, which were 1.6-1.7 times higher than in the other sections. The spatial distribution of heterotrophic bacterioplankton in the Ob River is mainly determined by the dynamics of water masses and the influence of tributaries and cities.

This paper presents a model for analyzing contestant progress in real-time coding contests, emphasizing the critical need for effective measures in assessing code similarity and plagiarism cases. Current coding contest platforms often need more robust procedures to identify and address these issues, compromising the integrity of the evaluation process. To tackle these challenges, we propose a novel system that leverages advanced techniques to analyze code and collective behavior, providing a holistic evaluation of submissions. The system enhances performance assessment accuracy and maintains fairness and credibility in real-time coding contests. The findings and insights from this study shed light on the importance of integrating sophisticated mechanisms to ensure the authenticity of code submissions and uphold the competitive nature of coding competitions.
Triadic effects in dynamic networks modelling
Authors:   , Juozaitienė Rūta
Published: July 2024

Statistical network analysis has become an essential methodological framework for modelling and analysing complex systems in a variety of domains. In many cases, the underlying network structure is non-static, with links existing only intermittently. Scientific literature states that triadic closure is a key driving force behind more complex social interactions. The triadic closure hypothesis contends that new links in a network arise preferentially between nodes having common ties. The idea behind the triadic effect is that established relations create opportunities to meet and interact with new actors, for example the tendency of becoming friends with friends of friends. The aim of the thesis is to propose approaches for proper analysis and modelling of triadic effects in dynamic networks. The dissertation presents a framework for testing triadic closure and triadic protection of ties in relational state networks. It also introduces a two-step approach for assessing the dynamical structure of reciprocal and triadic effects in relational event networks, that operates without arbitrary and possibly incorrect assumptions about the temporal aspect of network event processes. Moreover, the thesis uncovers how a failure to account for nodal heterogeneity can vastly overstate the prevalence of the triadic closure effect present in the relational event networks. The suggested frailty approach is capable of disentangling random nodal effects from triadic closure.

The training of pediatric specialists has gone through several stages over the years. The analysis of decision-making is essential in the training of this specialist. The aim of this work is to evaluate decision-making in the training of this professional, with its corresponding premises, stages, objectives, and concrete actions, following the logic of the Clinical Method. The feasibility and relevance of this proposal was corroborated by means of the Delphi Method, which makes it possible to calculate the numerical ray, and the identification of the different stages, objectives and concrete actions in the numerical range of excellence. This was also corroborated by Kendall's W statistical method through the assessment of a group of experts, who were previously selected for their level of competence on the subject.
Evaluation of the efficacy of a TCA medium peeling procedure combined with skin biorevitalization in face rejuvenation: a case series
Authors: SMIT Riekie
Published: July 2024

Background: Aging is triggered by both intrinsic and external factors. Although chemical peels with trichloroacetic acid (TCA) are used to reduce wrinkles and hyperpigmentation, they cannot help to enhance the other factors that contribute to overall skin quality. Objective: The aim of this case series was to compare the efficacy of 15% TCA peel alone versus a combination of NCTF®135HA injection and 15% TCA for face rejuvenation. Methods: Six patients were treated on each side of their face with 15% TCA combined or not with NCTF®135HA. Each patient was subjected to one session of peeling on both sides of the face followed by three sessions of NCTF®135HA injections, on only one randomized side of the face, with an interval of two weeks between each treatment. Skin aging measures were assessed before and after treatments (D0 and D45). Results: At D45, clinical scoring demonstrated a significant difference in reducing the lower face sagging score, increasing skin hydration, and improving skin homogeneity on the side treated with NCTF®135HA combined with peeling compared to the side treated with peeling alone. There is a tendency for improvement in Crow’s feet only on the side treated with both peeling and NCTF®135HA, compared to the side treated with peeling alone. Both the evaluator and the patient reported a greater improvement on the side of the face treated with 15% TCA + NCTF®135HA on the Global Aesthetic Improvement Scale (GAIS). Conclusions: The addition of NCTF®135HA to 15% TCA chemical peel application significantly enhanced the peeling effect on skin aging features, this improvement was perceived by both subjects and the physician.
Exploring barriers to postpartum sterilization

Sterilization is a prevalent form of contraception, yet not all women who desire postpartum sterilization undergo the procedure. This retrospective cohort study aimed to investigate reasons for non-performance of postpartum sterilization. These reasons included lack of documentation, no longer desiring the procedure, and desiring another form of contraception. Undergoing cesarean delivery significantly increased the likelihood of undergoing postpartum sterilization, suggesting a need for prioritizing sterilization access amongst patients delivering vaginally. Further research is warranted to explore clinical decision-making and patient uptake of postpartum sterilization in larger samples. Addressing documentation issues may facilitate shared decision-making and improve access to sterilization.
