Maffeo Pantaleoni: Liberal Economist and the Crisis of the Liberal State in Italy
Authors: Melnik Denis
Published: February 2025

The article examines the intellectual and political biography of one of the most important (and least known outside Italy) representatives of Italian marginalism, Maffeo Pantaleoni (1857–1924). An outstanding economist and an uncompromising defender of economic liberalism, at the turn of the 19th and 20th centuries he entered into an uncompromising battle against the tendency towards increasing government interference and the formation of a welfare state. He saw the source of this tendency in the alliance between the economic interests of individual groups of the mass electorate and the political interests of the parliamentary parties. The attempt to find a force to counteract this tendency in the situation of the crisis of the Italian political system after the First World War led Pantaleoni to the camp of Benito Mussolini’s supporters. The peculiarities of Italy’s development after the unification provide the context for understanding the evolution of Pantaleoni’s approach. Pantaleoni himself and his supporters are designated in the article as “pure” liberals. Their approach was emerged as a continuation of the struggle waged by the supporters of economic liberalism led by Francesco Ferrara against their compatriots, the «Germanists» — economists whose approach was similar to that of the German Historical School. This struggle gained particular intensity in the 1870s. In the 1890s, the struggle for the ideals of economic liberalism flared up with new force — this time by the economists of Pantaleoni’s generation. They saw the main threat no longer in hostile ideas, but in the distortions of economic policy caused by the activities of liberal reformists — those politicians who considered it necessary to move away from the ideal of non-interference in favor of active government actions in order to accelerate economic development and smooth out social contradictions. The strategy of liberal reformism, not least due to the irreconcilable criticism of «pure» liberals, turned out to be firmly associated with the name of the Italian politician Giovanni Giolitti. The struggle of the 1890s inflicted significant damage on both sides. But at the beginning of the 1900s the Giolitti era began in Italian history, which ended only with the First World War. The persistent nature of the political distortions, which were initially explained by “pure” liberals primarily by subjective factors — the personality of Giolitti himself and the politicians of his circle — led Pantaleoni to move away from studying pure economic theory and to shift his attention to the peculiarities of political processes in an emerging mass society. This led to a sharp rejection of political movements oriented towards the masses, especially the Socialists, as well as to a pessimistic assessment of representative democracy.
Specified method of assessing the fire resistance of ribbed plates by loss of integrity
Authors: Sidnei Stanislav
Published: February 2025

An investigation was carried out to evaluate the immersion capacity of reinforced concrete ribbed slabs at the borderline stage of loss of integrity. EN 1992-1-2 has daily diversification methods for determining the limits and class of immersiveness of reinforced concrete slabs at the limiting point of loss of integrity (E). The scientific work is aimed at directly tracking the concentration of the two boundary conditions of the immersive capacity: non-bearing capacity (R) and thermal insulation capacity (I). Experimental testing is subject to criticism due to the difficulties of fixing the sign of the onset of the borderline stage of loss of integrity, despite the need to control the unheated surface of the ribbed slab after an hour. in the case of mechanical engineering. Even the methodology for carrying out destructuring before assessing the absorbency of reinforced-concrete ribbed slabs behind the boundary mill station loses no integ-rity. In order to ensure the safe evacuation of people in the event of a fire, the protection of more or unsafe officials, as well as the effective work of the military personnel, it is necessary to stagnate the civil servants design with guaranteed immersion resistance classes. The results of the most important thermal and static problems are presented, which are related to the distribution of temperature and the stress-deformation process of a ribbed plate. Carrying out research into the ingressivity of reinforced-concrete ribbed slabs with the protection of the boundary mill at the loss of integrity has made it possible to establish the deposits between the insulation of these structures at a loss integrity depending on the level of applied mechanical strength. Removing the laying schedule makes it possible to evaluate reinforced concrete ribbed slabs based on the criterion of the moment of the boundary stage of loss of integrity, which makes it possible to evaluate more objectively the immersiveness of such future constructions.

The relationship of neurotrophin levels with stress-induced urinary incontinence in multiparous premenopausal women
Authors: Ünal Kübranur , Latif Çöllüoğlu Musa , Erdem Elif , Özbas¸ Cansu , Özdemir Özhan
Published: February 2025

Objective: Urinary incontinence (UI) is involuntary urine leakage, mainly due to a feeling of high pressure in the abdominal part, the immediate and urgent need for micturition, or both. Neurotrophins (NTs) are a family of peptides that play a role in the regulation of nerve cells. Their effects on the lower urinary tract organs may provide a perspective to understand the development and diagnosis of UI. This study aims to investigate NT levels to understand how these molecules change in multiparous premenopausal women who suffer from stress-related UI. The study also evaluates diagnostic and distinguishing capabilities of NTs for these disorders.

Methods: In this cross-sectional case–control study, multiparous premenopausal women underwent a urodynamic examination, a stress cough test, and were evaluated with an International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Participants were divided into three groups: 29 healthy women in the control group and two patient groups consisting of 26 women diagnosed with stress urinary incontinence (SUI) and 33 women diagnosed with mixed urinary incontinence (MUI). Nerve growth factor (NGF), brain-derived neurotrophic factor, neurotrophin-3 (NT-3), and neurotrophin-4 (NT-4) levels in serum were measured by enzyme-linked immunosorbent assay. The body mass index (BMI) and ICIQ-SF scores of the patients were also calculated. The data obtained were compared between the groups. Receiver-operating characteristic analysis was performed to determine the role of NTs in diagnosing UI.

Results: The result showed that serum NGF and NT-3 levels were significantly low in both incontinence subtypes compared to the control group (p < 0.05). BMI scores and number of vaginal deliveries were higher in incontinence subtypes compared to the control group, and ICIQ-SF scores were higher in the MUI group.

Conclusion: The differences in serum NGF and NT-3 levels were observed in multiparous premenopausal patients with UI. There was a decrease in serum NGF levels in MUI patients and serum NT-3 levels in SUI patients. Although the changes in serum NGF and NT-3 levels were significant, their discriminatory potential was weak or moderate.

Published: February 2025

Background: Cancer is a significant global health challenge. One of the biggest health issues that cancer patients face is depression and anxiety. This has a significant impact on their quality of life and treatment outcomes.

Aim: The aim of this study was to investigate the frequency of depression and anxiety among cancer patients in Qatar.

Materials and methods: This study was a cross-sectional design using the Patient Health Questionnaire-9 (PHQ-9) and Generalized Anxiety Disorder-7 (GAD-7) scales. A total of 500 cancer patients were surveyed from the National Center for Cancer Care and Research in Doha.

Results: The study found that a significant proportion of cancer patients suffered from depression, with an average PHQ-9 score indicating mild levels of severity. Depression was commonly categorized as mild, with a smaller percentage experiencing moderate, moderate-to-severe, or severe depression. Additionally, patients were predominantly anxious, as reflected by an average GAD-7 score, with most patients experiencing mild to moderate symptoms, while a few experienced moderate or severe anxiety. These findings highlight the significant prevalence of both depression and anxiety among cancer patients, pointing to the importance of comprehensive mental health support. Moreover, patients with advanced-stage cancer, those in their 40s and 60s, those undergoing radiotherapy or hormone therapy, and female patients were found to be more susceptible to depression and anxiety.

Conclusion: Treatment of mental health issues is essential to enhancing the effectiveness of cancer treatment. Cancer patients can have a higher quality of life and better adherence to cancer treatments when mental illnesses such as depression and anxiety are identified and treated early. Furthermore, most patients reported having depression and anxiety, according to the study, which showed that these conditions were more common in Qatar than in other countries. Several demographic groups have been linked to higher rates of depression and anxiety, including women, middle-aged adults, people with stage IV cancer, and patients receiving therapies such as radiotherapy and chemotherapy.
The effect of SLC5A5 gene expression in tumor tissues on refractoriness to radioactive iodine treatment of differentiated thyroid carcinomas
Authors: Erten Aslı , Sayiner Zeynel Abidin , Erkılıç Suna , OğFuzkan Balcı Sibel , Akarsu Ersin
Published: February 2025

Background and objective: The majority of thyroid cancer patients have a good prognosis. Even in advanced disease, the radioactive iodine (RAI) response improves the prognosis. However, RAI refractoriness poses a significant challenge for these patients. The objective of the study was to assess the expression of SCL5A5 as a potential marker for predicting future resistance to radioiodine treatment.

Materials and methods: Radioactive iodine-refractory papillary thyroid carcinoma (RAIR-PTC) and iodine-sensitive papillary thyroid carcinoma (PTC) were included in the study. Demographic and clinicopathological data were retrospectively analyzed. RNA samples were converted to cDNA. Gene expression reactions were performed using synthesized solute carrier family 5 member 5 (SLC5A5) and glyceraldehyde-3-phosphate dehydrogenase (GADPH) primer samples.

Results: Of the patients, 51 (61.4%) had iodine-sensitive PTC and 32 (38.5%) were RAIR-PTC. Patients were followed up for 8 ± 6.4 years. The mean age at diagnosis was higher in the RAIR-PTC group (56.56 ± 15.22 years vs. 46.82 ± 12.43 years, p = 0.002). The PTC group had higher SLC5A5 gene expression than RAIR-PTC. In addition, no statistically significant correlation was observed between basal thyroglobulin levels and tumor standardized uptake value-maximum (SUV-max) on fluorodeoxyglucose positron emission tomography (p = 0.304).

Conclusion: SLC5A5 gene expression is reduced in radioactive iodine-refractory thyroid carcinoma. Furthermore, the decreased expression status of the SLC5A5 gene before preablative iodine treatment may serve as a predictive indicator of future resistance to RAI therapy.

Acute pancreatitis is an uncommon cause of abdominal pain in childhood. The diagnosis is made by classical presentation of epigastric pain, with typical clinical examination findings, elevated levels of amylase and lipase and imaging findings. Practically, measurement of enzyme levels is used to screen for pancreatitis in children presenting with abdominal pain, since lipase levels have high negative predictive value in diagnosis of acute pancreatitis. But recently, we managed a child with pancreatitis, who had normal enzyme levels. In this case report, we are presenting the details of the case, along with literature review on acute pancreatitis with normal enzyme levels.

This paper introduces the concept of Pentapartitioned Neutrosophic Numbers (PNNs) and proposes score and accuracy functions to effectively rank PNNs based on their score values. Utilizing the adaptability of Dombi operators to accommodate various parameters, the study applies these operators to address complex Multicriteria Attribute Group Decision Making (MAGDM) problems. To achieve precise aggregation under neutrosophic conditions, Dombi T-norm and T-conorm operations for two PNNs are defined. Building upon these Dombi operations, the paper presents two weighted aggregation operators—PNDWAA (Pentapartitioned Neutrosophic Dombi Weighted Arithmetic Average) and PNDWGA (Pentapartitioned Neutrosophic Dombi Weighted Geometric Average)—and investigates their properties within the pentapartitioned neutrosophic environment. Furthermore, the study explores a Multicriteria Attribute Decision Making (MADM) approach that utilizes either the PNDWAA or PNDWGA operators for decision-making.An illustrative example is provided to demonstrate the proposed method, offering a detailed step-by-step process that highlights the effectiveness of the approach in determining the optimal alternative based on ranking order.

Conformity Model in Social Network Opinion Formation
Authors: Liu Zhiwei
Published: February 2025

The advent of social media has profoundly influenced how public opinion is formed and consolidated. This paper delves into the intricate dynamics of opinion stabilization within various network structures and examines the role of conformity in the opinion formation process. Drawing on existing theoretical frameworks, including social psychology and evolutionary game theory, this study uses agent-based modeling to simulate opinion dynamics across different network topologies. This study compares the mean stabilization times across basic structures (star, ring, tree) and complex structures (BarabsiAlbert, Watts-Strogatz, Scale-Free, random graph), considering variations in group size. For simple social networks, linear model analysis indicates that a larger network size, a larger network diameter, smaller density, and higher measures of betweenness, degree, closeness, and eigenvector centralities are statistically significant in relation to longer average opinion stabilization times. For complex structures, linear model analysis indicates that a larger network size, a smaller network diameter, larger density, and higher measures of degree, closeness, and eigenvector centralities, along with lower measures of betweenness centrality, are statistically significant in relation to longer average opinion stabilization times.
Analysis of the Dilemma of the Responsibility to Protect and Reconstruction of Norms: A Review
Authors: Wu Jingen
Published: February 2025

As an important theory in the field of humanitarian protection, the responsibility to protect has not been adequately adapted to the practical situation, and is prone to produce unfavorable consequences beyond the scope of humanitarian protection. Based on in-depth investigation of the dilemma of the responsibility to protect in the application, in order to explore the possible path of improvement. This paper summarizes the past literature at home and abroad, and focuses on the case of humanitarian intervention in Libya. The findings reveal that the "Responsibility to Protect" faces challenges in practice, including "unclear triggering conditions," "excessive costs of action," and "lack of post-intervention reconstruction measures," all of which hinder its practical effectiveness. In order to improve the theoretical framework of the responsibility to protect, we can draw on the theoretical perspective of responsible protection, while actively promoting the establishment of a more equitable and just international political and economic order.

Authors: Zhang Shuai
Published: February 2025

Interpreting, including simultaneous and consecutive interpreting, is one of the most significant means of intercultural communication. Different factors can affect the content of output of consecutive interpreting, including the speakers accent, the delivery rate of the source speech, tiredness, note-taking, environmental noise and personal factors. Among these factors, the factor of noise will be the focus of this research. In this research, the author conducts experiments for professional and non-professional translators by means of questionnaires and case studies, aiming to summarize and analyze the different translation strategies and techniques preferred and adopted by various groups of translators when faced with noise during consecutive interpreting, as well as exploring the reasons why these differences occur. The preliminary conclusion is that professional translators have a richer and more systematized knowledge base of translation, while the non-professional translators have a less completed one. More details and analysis will be discussed in the text.

This paper investigates the impact of the COVID-19 pandemic on the mental health of on-campus students in China, with a focus on the pre-, during, and post-pandemic periods. The pandemic has disrupted traditional college life, as students faced prolonged isolation, online learning, and limited social interaction. Drawing on mental health criteria, including self-security, emotional stability, and social connectedness, the paper explores the primary psychological issues affecting students, such as anxiety, social withdrawal, internet dependency, and stress from online education. The study highlights that while social media has helped maintain peer connections, it cannot fully substitute for in-person interactions essential to students development. Findings underscore that pandemic-related disruptions led to increased stress and a mix of fear and anticipation for offline experiences. Consequently, the study recommends enhancing both online and offline mental health support, along with improving early warning systems for psychological issues. Despite limitations related to data scope and regional disparities, this paper provides insights into the unique mental health challenges faced by students and calls for future research on the long-term effects of virtual contact on student mental well-being.

Published: February 2025

For fresh supermarkets, it is crucial to formulate restocking decisions and pricing strategies that maximize profits while meeting market demand. This paper mainly studies the automatic pricing and restocking decisions for vegetable products. Through model assumptions, correlation analysis, and time series methods, the study investigates these decisions. Based on the obtained sales data, Pearson correlation coefficients are calculated to analyze the relationships between different categories and individual product sales. A Long Short-Term Memory (LSTM) time series model is built to forecast future costs, with the model parameters estimated using the least squares method. The optimal restocking and pricing strategies are derived using Random Forest and Autoregressive Integrated Moving Average (ARIMA) models. Additionally, the restocking and pricing problems are treated as a combinatorial optimization problem and solved using a mixed-integer linear programming model to maximize revenue. This paper emphasizes the importance of comprehensive data collection in automatic pricing and restocking decisions to address challenges in the industry.

Published: February 2025

The THESAN Project combines the successful IllustrisTNG galaxy simulation framework with advanced radiation transport, non-equilibrium heating and cooling, realistic ionizing sources, and a cosmic dust model. Conducted on some of the worlds most powerful supercomputers, THESAN consists of high-resolution Flagship simulation, which balances physical accuracy and box size to resolve hundreds of thousands of galaxies in a region of the universe spanning over 300 million light years. THESAN offers higher resolution than previous simulations of similar volume and employs galaxy formation simulations that match observations up to the present-day Universe. Its findings today align almost perfectly with recent observations. This study explains how THESAN accurately simulates different fields, e.g., having to consider concepts such as escape fractions and dark matter models. Moreover, to minimize errors, this simulation incorporated softening, which reduces gravitational forces on scales of 2.2ckpc. The success of this project was also due to the assistance of other simulations, including the efficient radiation hydrodynamics solver AREPO-RT, which is explained later, that can capture the interaction between ionizing photons and gas and IllustrisTNG that can predict the properties of galaxies. With THESAN simulations, humanity will be able to understand interactions both within the IGM and the future Universe.

The Influence of Epigenetics on Gene Expression: Mechanisms, Environmental Interactions and Clinical Applications in Disease Prevention and Treatment
Authors: Ao Yun
Published: February 2025

Epigenetics, as defined, is a crucial field of heritable modifications in gene activity or function independent of genetic DNA code variability. Determining this knowledge is very important. The review will elaborate on the principal epigenetic mechanisms comprising DNA methylation, histone modifications, and non-coding RNAs. Each bears responsibilities for being a major contributor to specifying gene expression as well as guardians for maintaining genomic stability. It also covers the impact of environmental factors, including nutrition, psychosocial stress, and toxic exposure, on changing epigenetic states often associated with shifts in disease susceptibility. By focusing on paradigmatic examples like the Dutch Hunger Winter study and research on chronic stress, this review illustrates that epigenetic changes can last many generations, hence affecting health even when the exposures occur far from the temporal context of an individual.
Effects of Muscle Stretching on Muscle Flexibility and Strength: A Literature Review
Authors: Chen Boyang
Published: February 2025

For numerous years, stretching has been a widely employed technique across various sports disciplines. One of the primary factors influencing the effect on range of motion post-stretching is muscle-tendon stiffness (MTS). Recently, researchers have made groundbreaking discoveries, revealing that stretching can significantly enhance movement range by effectively decreasing MTS. While traditional static stretching has been a staple in warm-up routines, it also appears to adversely impact exercisers' strength performance, raising concerns among athletes and coaches alike. In response to these findings, various studies have introduced alternative stretching forms such as dynamic stretching and proprioceptive neuromuscular facilitation (PNF) stretching, alongside long-term training programs. These innovative approaches aim to optimize the beneficial effects of stretching while mitigating its detrimental outcomes on strength and performance. To comprehensively understand and delineate the immediate and prolonged impacts of both static and dynamic stretching, along with the efficacy of different stretching protocols, this study meticulously examined recent research articles. The objective of this review is to propose a clear terminology and methodology for stretching practices, thereby providing guidance for exercise training and physical activities. By doing so, it seeks to enhance the efficiency and scientific rigor of stretching protocols, ensuring that athletes and fitness enthusiasts can reap the maximum benefits from their stretching routines.
Historical Evolution and CRISPR-Mediated Gene Editing Applications in NK Cell Therapy
Authors: Yan Ziqing
Published: February 2025

Natural Killer (NK) cell therapy has emerged as a transformative approach in cancer immunotherapy, driven by decades of research since their discovery in the 1970s. NK cells possess a unique ability to target tumor cells through antigen-independent recognition, which has been expanded with the discovery of antigen-specific memory and licensing mechanisms. This review explores the evolution of NK cell biology, highlighting key findings such as the enhanced response of NK cells upon re-exposure to cytomegalovirus (CMV), defying conventional immune paradigms. Recent advancements in gene editing, particularly with CRISPR technology, have led to the development of "armored" NK cells. For example, knock-in strategies have enabled the insertion of chimeric antigen receptors (CAR), enhancing tumor specificity, while knock-out approaches have improved NK cell activation by removing inhibitory molecules like PD-1 and NKG2A. Early clinical trials demonstrate improved tumor-targeting efficacy and reduced resistance. However, challenges remain, including high R&D costs, limited clinical data, and technical uncertainties such as off-target effects. In China, NK cell therapy is in its nascent stages, with increasing interest but limited clinical applications due to regulatory and funding barriers. This review provides a comprehensive analysis of NK cell evolution, CRISPR-based advancements, and future directions for overcoming current limitations and optimizing therapeutic outcomes.
