Today, the vast majority of civilian and military vehicles use internal combustion engines as a power plant. One of the ways to increase the economic efficiency of overhauling such engines is to maximize the residual life of the crankshaft. The life of the crankshaft depends on the wear resistance of the journal surfaces and the fatigue strength of the part. Therefore, when restoring crankshafts, it is necessary not only to preserve these surface properties, but also to improve them. The wear resistance of the surface of the part can be influenced by changing the chemical composition and structure of the surface layer or by changing the surface topography. There are many traditional processing methods that allow obtaining high wear resistance of friction surfaces. Analysis of these methods has shown that they have a number of disadvantages that do not allow ensuring the required level of operational characteristics of the restored surfaces, and cannot be used for restoring crankshafts. Over the past decades, in various branches of science and technology, there have been attempts to create new unconventional methods of increasing the wear resistance of parts, which would be devoid of many of the shortcomings of classical technologies. One of such methods is the method of forming a microrelief with combined roughness on the working surfaces of the main and connecting rod journals of crankshafts due to their discrete hardening. A set of full-scale laboratory studies of the tribotechnical characteristics and fatigue strength of the surfaces of parts after their discrete hardening by the proposed method has been carried out. The results of the studies have shown that discrete hardening of the working surfaces of the crankshaft journals with combined roughness leads to a significant increase in their wear resistance and resource.

The analysis of the nature of the armed struggle of the last decades shows a sharp increase in the influence of modern weapons, their condition, reliability indicators and operational characteristics on the technical readiness of military units to successfully perform their assigned tasks. The level of technical readiness of units is determined by proper technical equipment, the level of staffing of units with weapons and military equipment, and the level of readiness of weapons samples for use. A methodology for assessing the technical readiness of military units to perform assigned tasks has been developed. The technical readiness of a military unit to perform assigned tasks is determined by the probability that at the time of performing combat tasks in the unit, the required amount of equipment will be operational, and starting from this point in time, it will function without fail during the time of performing combat tasks (as assigned tasks). A control algorithm is proposed that implements the proposed methodology and allows, based on the analysis of the received data, to form decisions on increasing the effectiveness of measures aimed at improving the indicators of the technical readiness of units to perform assigned tasks. The control algorithm provides for the following procedures: collection, processing, analysis of information on the staffing of units with weapons and equipment, technical condition, reliability indicators and operational characteristics of weapons samples; assessment of the probability of equipping units with weapons and military equipment; evaluation of operational readiness coefficients of weapons and military equipment samples; assessment of the probability of readiness of a sufficient number of samples of weapons and military equipment of the units to perform tasks as assigned; assessments of the technical readiness of units to perform assigned tasks; formation of a decision to improve indicators of the technical readiness of units to perform assigned tasks; analysis of the effectiveness of measures to improve indicators of the technical readiness of units to perform assigned tasks and correct the decision.

The article is devoted to the topical issue of using wargaming during educational war games. Purpose is the study of the etymology of the concepts of "war game" and "wargaming", foreign education and methodological features of wargaming with the aim of developing its use during the training of military specialists in the Armed Forces of Ukraine. Methods are: a systematic approach, content analysis of the legal framework and scientific literature on the researched problem, systematization and generalization, comparing of theoretical views and approaches. The etymology of the concepts "war game" and "wargaming", their purpose and goals, foreign experience and methodical features of wargaming during the professional training of military specialists are studied. The existence of significant ethical issues and features of conducting wargaming using artificial intelligence during the study of a number of problems of the security and defense environment in the world has been clarified. The article discusses and defines the semantic aspects of the use of wargaming during war games to ensure the professional training of military specialists. The purpose of the war game is to analyze the progress of the battle, the development of situations and the development of decisions, including the necessary countermeasures. The goals of the war game are the organization of interaction, the identification of operational plan deficiencies, risks and opportunities, situations that require a commander's decision, compliance with critical requirements for information, and a deep understanding by the participants of the actions of the goals of the actions taken and the contribution of everyone. The goals of training wargaming during war games are to understand the elements of the decision-making process that are practiced and developed using individual players. The goal of wargaming is the development of certain cognitive skills. There is a problem with simply using simulations and wargaming to test DoD concepts, capabilities, and plans. In addition to technology, new ways of thinking and a new approach to decision-making are needed. The prospect of successful use of wargaming in the process of military decision-making is based on the combination of two complex objects - human and artificial intelligence, which is already becoming an important task today.

Objective: Toxoplasma gondii is an obligate intracellular protozoan of significant veterinary and medical concern, as it causes toxoplasmosis, a disease that is easily transmissible and presents in various infectious forms. This review aims to explore the complexities of T. gondii transmission and pathogenesis, as well as the challenges in developing effective vaccines. Methodology: To produce the article, a literature review was carried out based on books and experimental papers through searches in Google, academic databases and PubMed. Impact: Toxoplasmosis remains a widespread public health and veterinary issue, particularly in immunocompromised individuals, where the disease can lead to more severe outcomes. We highlight comprehensive analysis of T. gondii’s life cycle, transmission routes, and mechanisms of host infection is presented. The review focuses on the parasite's ability to invade nucleated cells in the intermediate host, such as macrophages, epithelial cells, and neural and muscle cells, ultimately leading to the formation of cysts that contribute to chronic infection. Despite numerous studies on the parasite, the lack of an effective vaccine continues to hinder progress in disease prevention and control. Findings and Unique Contributions: This review highlights the sophisticated mechanisms by which T. gondii infects host cells and the chronicity of the disease through cyst formation. It emphasizes the ongoing gap in vaccine development, underscoring the urgent need for innovative approaches to vaccine design. The study offers a critical perspective on the current understanding of T. gondii biology and challenges in creating lasting immunity against toxoplasmosis, making it a valuable contribution to the field.

Global dependence on fossil fuels has generated significant environmental consequences, such as increased greenhouse gas emissions, air pollution and climate change. In response to these challenges, there is growing interest in alternative energy sources that are more sustainable and less harmful to the environment. Hydrogen appears as a promising alternative due to its high energy capacity and the fact that its direct combustion generates only water as a by-product, without emission of atmospheric pollutants. The aim of this article is to explore the feasibility and benefits of bacterial anaerobic fermentation as an effective strategy for hydrogen production. Literature data highlights that this approach not only provides a clean energy source, but also contributes to sustainable waste management. This type of fermentation offers an economical and accessible alternative to hydrogen production, using organic waste by-products from industrial or agricultural activities, reducing production costs and reducing environmental impacts. The study addressed the theoretical and practical foundations of this technology, its challenges and opportunities, and how it can be integrated into broader strategies for a more sustainable energy future.

The AI-Enabled Instructor: Three Methods for Enhancing Political Science Learning
Authors: Peters Sean
Published: January 2025

The explosion of artificial intelligence tools in recent years has created a rich environment for scholars, both in improved research and in the creation of novel methodologies. Yet in conceptually abstract fields like the social sciences these tools may prove useful as well. I present three AI-enabled methods for enhanced instructional ability, each targeting a different component of the learning and instructional process, and unified under a framework known as ClassFactory. ClassFactory aims to assist instructors in three key areas of lesson preparation, course alignment, and student assessment. ClassFactory includes BeamerBot: an AI-powered lesson generator yielding a set of lecture slides in LaTeX; ConceptWeb: a module leveraging AI to perform relation extraction and community detection methods to generate interactive knowledge graphs; and QuizMaker: an automated quiz generator drawing directly from course readings. Taken together, these methods have the potential to significantly reduce instructor administrative workload while simultaneously enhancing student learning.

Chitooligosaccharides suppress airway inflammation, fibrosis, and mucus hypersecretion in a house dust mite-induced allergy model
Authors: Kim Yun-Ho , Park Chan-Ho , Kim Ju Myung , Yoon Yeo Cho
Published: January 2025

Background

Respiratory allergy is a serious respiratory disorder characterized by inflammation, mucus hypersecretion, and airway tissue sclerosis. Disruption of the T helper 1 (Th1) and T helper 2 (Th2) immune systems by stimuli induced by house dust mites (HDM) and fine particulate matter leads to the secretion of various inflammatory cytokines, resulting in immune respiratory diseases characterized by airway inflammation. Chitooligosaccharides (COS) are known for their antioxidant and anti-inflammatory properties.

Methods

Human airway epithelial cells (BEAS-2B) were cultured in DMEM/F12 medium containing COS at concentrations of 25–100 µg/ml for 24 h. No intracellular toxicity was observed up to 1,000 µg/ml. Cell experiments were conducted at COS concentrations below 100 µg/ml, while animal experiments were performed at concentrations below 100 mg/kg body weight for 4 weeks. Samples of right lung tissue obtained from the experimental animals were used for gene and protein expression analysis, whereas samples of contralateral lung tissue were used for immunohistochemical analysis.

Results

COS regulated Th1 immunity by inhibiting major cytokines, including inflammatory tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6), in BEAS-2B cells. In the HDM-induced allergic respiratory model, COS suppressed the infiltration of inflammatory cells around the airways and inhibited the mRNA expression of Th1 immune cytokines in lung tissues, while also reducing the expression of nuclear factor kappa B (NF-κB)-related proteins. Furthermore, the results confirmed the suppression of the levels of immunoglobulin E (IgE) in the blood secreted by mast cells activated by HDM, which led to a reduction in allergic mucus hypersecretion and airway sclerosis.

Conclusion

In summary, COS are thought to improve airway resistance by alleviating inflammatory allergic respiratory diseases caused by HDM and are regarded as substances that regulate the balance of the Th1 and Th2 immune systems in epithelial cells affected by mucus hypersecretion.
Lamb survivability: a new approach to an old problem
Authors: Wilson Carrie S. , Cherry Natalie L. , Taylor J. Bret
Published: January 2025

Lamb survivability is an important trait from both an economic and animal welfare perspective. Five breeds at the U.S. Sheep Experiment Station were evaluated for survival to weaning and included 74,448 records from 43 years. Objectives were to evaluate 1) the influence of lamb and littermate competition on lamb survivability to 3 d and 120 d (weaning); 2) the influence of within-litter competition on birth weight; 3) the relationship between within-litter birth weight deviation and lamb survivability, 4) the influence of ewe age on lamb survivability and birth weight, and 5) reasons for and timing of lamb loss. Sex of littermate(s) had an impact on lamb survivability, which was more pronounced for triplets than for twins. Although not significant, female birth weights were lighter in mixed-sex litters than all-female litters. Within-litter birth weight deviation had an impact on lamb survivability with lambs from below mean weight litters that were more than 1 kg lighter than the litter having less than a 50% chance of survival. Both young and old ewes had lower lamb survival than mid-age ewes. Reasons for lamb loss differed depending on the age of the lamb with weak and trauma categories resulting in early loss and predation resulting in later loss. This study provides insight into within-litter competition for use in future genetic evaluation.
Co-evolution of fish and rice farming by Austroasiatic communities in the Neolithic Era and early documentation of aquaculture in China
Authors: Edwards Peter
Published: January 2025

This paper is a review of the co-evolution of fish and rice farming about 10,000 years ago in the early Neolithic Era in China. China is often referred to as the origin of fish farming based on an oft cited document of Fan Li (448 BC – 536 BC) about 2,500 years ago. It is the earliest account of farming common carp (Cyprinus carpio) but its origin dates back much further. Oracle bone scripts of the Shang Dynasty (1,046 BC – 1,600 BC) are the earliest written record of fish farming in ponds. Farming common carp was prohibited in the Tang Dynasty (618 AD-907 AD) because the name of the fish, Li, was the same as that of an emperor, and this possibly led to farming Chinese carps in polyculture. There were increases in temperature and rainfall at the end of the last ice age in the Yangtze River Basin during the early Neolithic Era about 8,000 BC, drivers for subsequent development. A vast freshwater environment of inland lakes and swamps developed, with wetland plants including wild rice, as well as fish, bordered by deciduous forests and semi-arid grasslands on higher land. This enabled Austroasiatic people to gather wild foods, terrestrial and aquatic nuts as well as fish and rice. A mixed economy of hunting, gathering and fishing evolved into the co- evolution of fish and rice farming.
Metagenomic next-generation sequencing for lung cancer low respiratory tract infections diagnosis and characterizing microbiome features
Authors: Liu Yao , Yang Bohan , Qi Qi , Liu Shijie , Du Yiheng , Ye Linlin , Zhou Qiong
Published: January 2025

Background

The capability of mNGS in diagnosing suspected LRTIs and characterizing the respiratory microbiome in lung cancer patients requires further evaluation.

Methods

This study evaluated mNGS diagnostic performance and utilized background microbial sequences to characterize LRT microbiome in these patients. GSVA was used to analyze the potential functions of identified genera.

Results

Bacteria were the most common pathogens (n=74) in LRTIs of lung cancer patients, and polymicrobial infections predominated compared to monomicrobial infections (p<0.001). In diagnosing LRTIs in lung cancer patients, the pathogen detection rate of mNGS (83.3%, 70/84) was significantly higher than that of sputum culture (34.5%, 29/84) (p<0.001). This result was consistent with that of non-lung cancer patients (p<0.001). Furthermore, in the specific detection of bacteria (95.7% vs. 22.6%) and fungi (96.0% vs. 22.2%), the detection rate of mNGS was also significantly higher than that of CMTs mainly based on culture (p<0.001, p<0.001). However, in the detection of CMV/EBV viruses, there was no significant difference between the detection rate of mNGS and that of viral DNA quantification (p = 1.000 and 0.152). mNGS analysis revealed Prevotella, Streptococcus, Veillonella, Rothia, and Capnocytophaga as the most prevalent genera in the LRT of lung cancer patients. GSVA revealed significant correlations between these genera and tumor metabolic pathways as well as various signaling pathways including PI3K, Hippo, and p53.

Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) caused an outbreak in 2002-2003, spreading to 29 countries with a mortality rate of about 10%. Strict quarantine and infection control methods quickly stopped the spread of the disease. Later research showed that SARS-CoV came from animals (zoonosis) and stressed the possibility of a similar spread from host to human, which was clearly shown by the COVID-19 outbreak. The COVID-19 pandemic, instigated by SARS-CoV-2, has affected 776 million confirmed cases and more than seven million deaths globally as of Sept 15, 2024. The existence of animal reservoirs of coronaviruses continues to pose a risk of re-emergence with improved fitness and virulence. Given the high death rate (up to 70 percent) and the high rate of severe sickness (up to 68.7 percent in long-COVID patients), it is even more critical to identify new therapies as soon as possible. This study combines research on antivirals that target SARS coronaviruses that have been conducted over the course of more than twenty years. It is a beneficial resource that might be useful in directing future studies.

Advances in high-throughput sequencing (HTS) have made it a powerful resource for the conservation of threatened species, providing information at both population and individual levels to inform management decisions. In South America, however, the application of HTS in conservation has been limited, primarily due to challenges in funding and access to advanced genomic equipment and analytical expertise. Darwin’s fox (Lycalopex fulvipes), endemic to Chile’s Valdivian Temperate Rainforest, is the most endangered canid in South America with a small and declining population estimated at less than 1000 mature individuals. Despite its endangered status, significant knowledge gaps remain. Here we highlight the potential of HTS to address these challenges, such as clarifying its taxonomy, demographic history, geographic distribution, population structure, genetic diversity, and pathogen exposure. Integrating molecular data into conservation planning will be pivotal in ensuring the long-term survival of Darwin’s fox by identifying priorities for targeted management interventions, highlighting areas of critical habitat for conservation, and guiding genetic rescue efforts to enhance genetic diversity and resilience.

Published: January 2025

Background

Heart failure (HF) is a clinical syndrome resulting from structural damage or dysfunction of the heart. Previous investigations have highlighted the critical involvement of immune cells in the progression of heart failure, with distinct roles attributed to different types of immune cells. The objective of the current research was to explore the potential connections between immune characteristics and the development of HF, as well as to ascertain the nature of the causality between these factors.

Methods

To assess the causal association of immunological profiles with HF based on publicly available genome-wide studies, we employed a two-sample Mendelian randomization technique, utilizing the inverse variance weighted (IVW) method as our primary analytical approach. In addition, we assessed heterogeneity and cross-sectional pleiotropy through sensitivity analyses.

Results

A two-sample Mendelian randomization (MR) analysis was conducted using IVW as the primary method. At a significance level of 0.001, we identified 40 immunophenotypes that have a significant causal relationship with HF. There is a significant causal relationship between these phenotypes and heart failure. These immunophenotypes, 8 of which were in B cells, 5 in cDC, 2 in T cell maturation stage, 2 in monocytes, 3 in myeloid cells, 7 in TBNK and 13 in Treg. Sensitivity analyses were conducted to validate the strength and reliability of the MR findings.

Conclusions

Our study suggests that there appears to be a causal effect between multiple immune cells on heart failure. This discovery provides a new avenue for the development of therapeutic treatments for HF and a new target for drug development.

Introduction

Ambient acoustic detection and localization play a vital role in identifying events and their origins from acoustic data. This study aimed to establish a comprehensive framework for classifying activities in home environments to detect emergency events and transmit emergency signals. Localization enhances the detection of the acoustic event's location, thereby improving the effectiveness of emergency services, situational awareness, and response times.

Methods

Acoustic data were collected from a home environment using six strategically placed microphones in a bedroom, kitchen, restroom, and corridor. A total of 512 audio samples were recorded from 11 activities. Background noise was eliminated using a filtering technique. State-of-the-art features were extracted from the time domain, frequency domain, time frequency domain, and cepstral domain to develop efficient detection and localization frameworks. Random forest and linear discriminant analysis classifiers were employed for event detection, while the estimation signal parameters through rational-in-variance techniques (ESPRIT) algorithm was used for sound source localization.

Results

The study achieved high detection accuracy, with random forest and linear discriminant analysis classifiers attaining 95% and 87%, respectively, for event detection. For sound source localization, the proposed framework demonstrated significant performance, with an error rate of 3.61, a mean squared error (MSE) of 14.98, and a root mean squared error (RMSE) of 3.87.

Discussion

The integration of detection and localization models facilitated the identification of emergency activities and the transmission of notifications via electronic mail. The results highlight the potential of the proposed methodology to develop a real-time emergency alert system for domestic environments.

Published: January 2025

Introduction

Solar photovoltaic (PV) power generation, a crucial part of global renewable energy, has been advancing swiftly. However, effective promotion of PV generation relies not only on enhancing generation efficiency but also on thorough evaluations of construction suitability. This study addresses this gap by developing a comprehensive evaluation framework for assessing the suitability of photovoltaic power station locations in China.

Methods

This research developed a subjective-objective evaluation framework that integrates the Analytic Hierarchy Process (AHP) and the Criteria Importance Through Intercriteria Correlation (CRITIC) method. This framework allows for a comprehensive analysis of photovoltaic power station location suitability. Long-term meteorological data and remote sensing products were used to calculate solar radiation and photovoltaic potential data, which were then applied to evaluate the suitability of photovoltaic generation across China.

Results

The study revealed that from 2000 to 2020, China's average annual solar radiation was 5,896.437 MJ·m−2, and the total photovoltaic generation amounted to 1.10726 × 1015 KWh. By 2020, the average score for photovoltaic construction suitability in China was 0.1058, with suitable areas comprising 51.1% of the national territory. High-suitability regions were primarily concentrated in Northwest China, including Xinjiang and Gansu, where suitability scores exceeded 7.5 and annual generation surpassed 213 KWh. In contrast, southeastern coastal and southern provinces such as Jiangsu, Zhejiang, and Fujian exhibited lower suitability scores (<3.5) and annual average generation of less than 19.2262 KWh, primarily due to limited land availability and reduced solar radiation.

Discussion

The findings emphasize the critical need to prioritize photovoltaic development in Northwest China, where favorable conditions offer considerable potential for large-scale photovoltaic generation. These regions possess rich solar resources and extensive land suitability, making them optimal for photovoltaic power station construction. In contrast, southeastern coastal areas and southern provinces are less suitable for photovoltaic development due to constraints in land availability and solar radiation levels. This study provides valuable insights for strategic photovoltaic development planning in China.
Role of hole depth on mechanical behavior and acoustic emission characteristics of pre-drilled sandstone
Authors: Liu Jiahan , Lei Ruide
Published: January 2025

To examine the influence of hole depth on the mechanical properties of rock, a series of uniaxial compression tests were performed on six groups of pre-drilled sandstone samples, each with varying depths. Also, multiple physical fields coupled with acoustic emission (AE) and digital image correlation (DIC) systems were synchronously employed to monitor the fracturing process. The study focused on characterizing the cracking fracturing, energy evolution, and fracture patterns in pre-drilled sandstones with different depths. The findings show that the peak strength of the sandstone decreases linearly with the increase of hole depth. The fracture mode transits from simple unilateral spalling to a complex fracture mode characterized by multiple fractures and spalling. AE analysis shows that the deeper the borehole, the lower the AE signal frequency, indicating fewer but more significant fracturing events. With the increase of hole depth, the peak elastic energy of the sample decreases from 29.81 kJ/m3 to 22.65 kJ/m3, and the dissipated energy increases from 4.48 kJ/m3 to 6.25 kJ/m3. Moreover, the AE energy of the pre-drilled sandstone displays distinct multifractal spectrum features under different stress levels. The multifractal spectrum width (Δα) varies from 0.419 to 0.227, suggesting that small-scale fracturing events predominantly govern the failure mechanism. DIC observation shows that the major principal strain concentration mainly occurs around the hole. The monitoring points around the hole show that the cumulative strain at P2 and P6 is significantly higher compared to other regions. Furthermore, it is observed that the stress release pathways originating from newly formed cracks and dislocation slips become more diversified, suggesting a more complex fracturing mechanism.
