Abstract
In this study, we investigated the effect of a rotation field and magnetic field on a homogeneous photo-thermoelastic nonlocal material and how its thermal conductivity changes as a result of a linearly distributed thermal load. The thermal conductivity of an interior particle is supposed to increase linearly with temperature under the impact of laser pulses. Microelastic (microelements distribution), non-local semiconductors are used to model the problem under optoelectronic procedures, as proposed by the thermoelasticity theory. According to the microelement transport processes, the micropolar-photo-thermoelasticity theory accounts for the medium’s microelongation properties. This mathematical model is solved in two dimensions using the harmonic wave analysis. Non-local semiconductor surfaces can generate completely dimensionless displacement, temperature, microelongation, carrier density, and stress components with the appropriate boundary conditions. The effects of thermal conductivity, thermal relaxation times, magnetic pressure effect, laser pulses, and rotation parameters on wave propagation in silicon (Si) material are investigated and graphically displayed for a range of values.

Abstract
We present new AMS 14C dates and technological characteristics of an enigmatic osseous implement – the T-shaped antler axe. T-shaped axes (T-axes) are made of red deer (Cervus elaphus L.) antler beams with the perforation for a shaft through the removed trez tine. Our study centres on 33 axes from Belarus, Latvia and Lithuania, most of which were found during drainage of wetlands or sediment extraction in the 20th century, and thus remained unknown internationally. We successfully dated 19 of these artefacts, and here we compare their dates to published dates of T-shaped antler axes from western Europe (Belgium, The Netherlands, western Germany, Scotland), the southwestern Baltic (Denmark, northern Germany and northwestern Poland) and southeastern Europe (Ukraine). Radiocarbon results suggest the gradual spread of this specific antler tool producing technique from southern Europe towards the Baltic during the 6th millennium BC. The technological characteristics of T-axes in combination with the radiocarbon data enable us to preliminary discuss the chronology of aspects of T-axe production.
The State of the Sanatorium-Resort Sphere of the Baikal Region in the Post-Pandemic Period
Authors: Rubtsova Natalia , Rzhepka Elina 
Published: February 2024

As a result of the geopolitical crisis of the third decade of the XXI century in Russia, the number of available foreign destinations has decreased, which has led to a renewed interest of Russians to sanatorium and resort vacations within the country. As a result, sales in some sanatorium and resort facilities this year exceeded the figures of three years ago. At the same time, the cost of sanatorium and resort treatment in popular health resorts in the country increased to 40 %. The key factors stimulating the growth in demand for holidays in Russian sanatoriums, according to experts, are not only the inaccessibility of foreign destinations, but also the popularization of the tourist cashback program, as well as the effect of pent-up demand - during the COVID-19 pandemic, Russians refused to travel, resuming them after the removal of most health restrictions. However, the situation in the industry as a whole is not the same. Resorts located in regions with the greatest transport accessibility turned out to be in a winning position. On the territory of the regions of the Baikal region (Irkutsk region and the Republic of Buryatia) there is an almost complete range of sanatorium-and-spa institutions. Nevertheless, having significant potential, the sanatorium and resort sphere of the regions of the Baikal region still lags behind the industry leaders. The purpose of the article was to characterize the state and forecast development trends in the sanatorium and resort sector of the regions of the Baikal region in the post-pandemic period.

Purpose: As technology advances, electronic devices have become ubiquitous among individuals of all backgrounds. From mobile phones to computing devices, people rely on these tools on a daily basis for both personal and professional purposes. The presented research seeks to investigate the extent to which individuals are being monitored in the digital realm and identify solutions to safeguard citizens from the threat of mass surveillance.
Findings: In the modern era, it is common for people to utilize various devices for a multitude of purposes, such as search engines and social networks. However, many are unaware that the information they share online is not always erased from cyberspace. This study aims to shed light on how this data is obtained and utilized and the potential risks humanity faces if privacy is not safeguarded in the digital age.
Research limitations/implications: The objective of this research is to thoroughly examine the current scientific literature, studies, and articles regarding the perils of surveillance in the digital era. The paper aims to highlight the challenges associated with combating surveillance. In the concluding section of the analysis, a concise set of recommendations will be provided, which are crucial to uphold in order to safeguard individuals' constitutional rights in the face of the potential ramifications of streamlined surveillance.
Originality/value: In today's digital age, it has become almost universal for people to communicate through electronic devices in cyberspace, whether for work or personal purposes. Unfortunately, this environment is often not secure, and automated surveillance models can be used to acquire people's data without their knowledge or consent. This raises serious concerns about privacy and the protection of fundamental human rights. That is why it is essential to conduct research that sheds light on the means of surveillance and explores ways to fight against it.
Digital Referendum - Effective Modeling of Public Administration in Georgia
Authors: Muradishvili Khatuna , Zakaradze Ekaterina 
Published: February 2024

State management in its content is a complex and at the same time dynamic process. The second half of the 20th century can be considered the initial period of management transformation and establishment of governance structures.
Governance based on democratic principles is based on a number of fundamental principles, the correct implementation of which is the most important prerequisite for the establishment of democratic institutions. One such important democratic process is the referendum.
In Europe, the practice of referendum is most established in Switzerland, which is governed by a system of direct democracy. Accordingly, in order to solve problematic issues, citizens in Switzerland take part in both regional and national referendums, which are undoubtedly democratic in content and respond to the fundamental principles of modern public administration.
In Georgia, where there is little experience in holding a referendum, the implementation of a digital referendum is the latest challenge, which will be an important step in the way of the country's European integration. The involvement of citizens in the solution of important issues for the state allows the so-called possibility of communication between society and government. It eliminates "black holes" and ensures the reduction of conflicts between them. Of course, all the positive results of the referendum depend on how fairly and objectively it will be conducted.
Thus, one of the important challenges of the digitalization of the public administration of Georgia is the digital referendum, the implementation and development of which is an effective step on the way of the state development of Georgia and as a result ensures the acceleration of the country's institutional and European integration processes.
In the era of digital governance, it is necessary to develop new approaches to state intervention in all spheres of public life and public service delivery systems in order to optimally respond to the needs of citizens. Analysis and comparison methods are mainly used in the work, proposals are given in the direction of improving the provision of public services in connection with the electronic referendum.
Molecular Insights of Excessive Water Cut during Cyclic Gas Injection in Liquid-Rich Shale Reservoirs: Contributions of Hydrocarbon Condensation and Water Trapping
Authors: Chen Fangxuan , Wang Shihao , Nasrabadi Hadi 
Published: February 2024

Summary
In a recent pilot test of cyclic gas injection (huff ‘n’ puff) in a Permian shale reservoir, excessive water product was observed, the reason for which remains unclear. In this work, we analyze the mechanisms of gas huff ‘n’ puff processes using molecular dynamics (MD) simulations and explain the reason for the high water-cut phenomenon. We aim to investigate the hydrocarbon-water-rock interactions during the gas injection as well as production within a shale rock in the pore scale. To mimic the heterogeneous pore structure of the shale rock, we have designed a pore system, including a bulk pore, a pore throat, and a dead-end pore. We simulate the distribution of different fluids during the initial equilibrium stage, the primary depletion stage, and the huff ’n’ puff stage. The results show that an excessive amount of water is trapped by the condensation mechanism in the larger pores during the primary depletion stage. The water is then recovered with the injection of working (lean) gases. Moreover, we have analyzed the effect of different injection gases (IGs) and found that carbon dioxide (CO2) yields a higher water cut compared with methane (C1). Moreover, our findings have revealed the trapping mechanisms of hydrocarbon-water mixtures in shale rocks and have highlighted the impacts of pore structures on the recovery of shale reservoirs. As such, we have provided a potential explanation of the observed phenomenon.
A Transfer Learning-Based Deep Learning Model for Automated Breast Cancer Identification in Mammograms
Authors: katiyar preeti 
Published: February 2024

Abstract
Breast cancer is a severe health issue that affects women worldwide, underscoring the need for reliable and effective screening techniques. The early detection, diagnosis, and treatment of breast cancer are made possible by computer-aided diagnostic (CAD) systems that rely on mammograms. This study introduces a unique deep learning model that uses transfer learning to identify and categorize breast cancer automatically. Several recent studies have shown that deep convolutional neural networks (DCNNs) can be used to diagnose breast cancer in mammograms with performances comparable to or even superior to those of human experts. To extract attributes from the Mammographic Image Analysis Society (MIAS) dataset, the proposed model uses pretrained convolutional neural network (CNN) architectures such as ResNet50 and Visual Geometry Group networks (VGG)-16. This novel deep learning model holds significant potential for enhancing the efficiency and accuracy of breast cancer detection and classification.

Published: February 2024

Abstract

Colorectal cancer is a global health challenge with high morbidity and mortality, but its causative factors remain unclear. In recent years, associations between various dietary patterns and colorectal cancer have been identified, but no studies have examined the association between macro- and micronutrient intake and colorectal cancer. This study analyzed the association between colorectal cancer and dietary intake using the logistic least absolute shrinkage and selection operator (LASSO). The data were derived from national data from the 1999–2010 National Health and Nutrition Examination Survey (NHANES) cycle. These data were further filtered to select those aged 50 years or older who self-reported having colorectal cancer (n = 168) and those who did not self-report having colorectal cancer (n = 649). LASSO regression is a new statistical shrinkage technique based on the R statistical software. In this study, LASSO was used to analyze the association between colorectal cancer and the variables from which the most relevant variables were selected. These variables included currently recognized risk factors for colorectal cancer and nutrients related to dietary intake. Age, sex, and race, which are recognised risk factors, still showed a significant association with colorectal cancer after LASSO regression shrinkage. For dietary intake of macro- and micronutrients, only thiamine (beta = 0.003) and zinc (beta = 0.0007) were positively associated with colorectal cancer. The results suggest that thiamine and zinc may be strongly associated with colorectal cancer. However, the results of the LASSO regression are based on statistically derived propensities and have not been validated by ex vivo experiments.
Characterization of Synoptic Systems Triggering Disasters in the State of Espírito Santo, Brazil
Authors: Silva Lindsay , Seluchi Marcelo Enrique 
Published: February 2024

Abstract
Despite the large amount of research about hydrometeorological disasters in southern Brazil, only a tiny part covers the State of Espírito Santo. The State is frequently affected by disasters of this nature. Therefore, this work aims to determine and characterize the types of synoptic systems that produce heavy rainfall and cause disasters in ES. Between 2013 and 2021, the S2ID database, synoptic charts from CPTEC, images from GOES 13 and 16 satellites, and precipitation data from INMET were used to select the dates and characterize the meteorological situation. Additionally, the ERA5 reanalysis was used for the construction of composite. It was found that disasters that affect ES occur mainly during the summer, which agrees with a thermodynamically more unstable atmosphere. The main systems identified can be described as follows: 1- Intense Frontal Systems related to blocking configuration in previous days that allow humid air advection from the Atlantic Ocean, through the presence of an anticyclone together with colder air at medium levels; 2- SACZ related to a warm anomalous anticyclone in the Atlantic and an intense low-pressure center located to the north, also showing a blocking pattern; 3- Troughs with slow displacement and low baroclinicity associated with high convective instability, acting as an extension of the Chaco Low and Thermo-Orographic Low, and 4- Cold core Cyclones with barotropic characteristics, located over ES, linked to warm blocking anticyclones, positioned south of about 40–45°S. In general, these patterns could be identified at least 48 hours in advance, observing disturbances at higher latitudes.
Analysis of Perfluoroalkyl Carboxylates and Perfluoroalkyl Sulfonates in Environmental Water by In-Port Arylation Gas Chromatography-Electron Impact Ionization-Mass Spectrometry

Published: February 2024

Abstract

Per- and polyfluoroalkyl substances (PFASs) are persistent environmental pollutants that have been used for various purposes. Although PFASs can pollute the environment in a variety of areas related to use, storage, and disposal of their products, there are insufficient data on the extent of PFASs pollution outside industrialized countries with their manufacturing facilities. Most of analyses depend on high-cost liquid chromatography-tandem mass spectrometry. In this study, we established a method to analyze anionic PFASs using gas chromatography-electron impact ionization-mass spectrometry with in-port arylation by diaryl iodonium. Extraction of PFASs from water samples was performed using solid phase extraction with reverse phase sorbent. Fourteen PFAS compounds could be detected from spiked water samples, and the detection limit ranged from 3.1 to 8.1 ng L− 1. Using this method, we analyzed groundwater samples from Okinawa Island, Japan, and detected PFASs up to a total concentration of 1.9 µg L− 1. This method uses relatively inexpensive analytical equipment, hence it can possibly enable surveys on PFAS contaminations in a wide range of regions and opportunities.

Abstract

Background
The in vitro maturation efficiency of porcine oocytes is relatively low and this limits the production of in vitro porcine embryos. Since melatonin is involved in the mammalian reproductive physiology, in this study, we have explored whether the endogenously produced melatonin can help the porcine oocyte in vitro maturation.
Results
We have found for the first time, that mitochondria are the major sites for melatonin biosynthesis in porcine oocytes. This mitochondrially originated melatonin reduces ROS production increases the activity of mitochondrial respiratory electron transport chain, mitochondrial biogenesis, and mitochondrial membrane potential and ATP production. Therefore, melatonin improves the quality of oocytes and their in vitro maturation. In contrast, the reduced melatonin level caused by siRNA to knockdown AANAT (siAANAT) is associated abnormal distribution of mitochondria and decreased the ATP level porcine oocytes and inhibits their in vitro maturation. These abnormalities can be rescued by melatonin supplementation. in addition, we found that siAANAT can switches the mitochondrial oxidative phosphorylation to glycolysis, a Warberg effect. This metabolic alteration can also be corrected by melatonin supplementation. All these activities of melatonin appear to be mediated by its membrane receptors since the non-selective melatonin receptor antagonist luzindole can blunt melatonin’s effects.
Conclusions
Taken together, the mitochondria of porcine oocyte can synthesize melatonin and improve the quality of oocyte maturation. The mitochondria of porcine oocyte can synthesize melatonin and improve the quality of oocyte maturation.These results provide an insight from novel aspect to study the oocyte maturation in the in vitro condition.
Neonatal meningitis induces ADHD-like behaviors via modulation of dopaminergic inputs by macrophages
Authors: Tanabe Shogo , Muramatsu Rieko 
Published: February 2024

Abstract
Neonatal meningitis often causes neurodevelopmental disorders, including attention deficit hyperactivity disorder (ADHD), in adulthood. However, the molecular mechanism by which neonatal meningitis induces brain dysconnectivity, leading to neurodevelopmental disorders, remains unclear. To investigate the pathological mechanisms of neonatal meningitis-induced neurodevelopmental disorders, we established mouse model of neonatal meningitis by injecting carrageenan, and found that mice with neonatal meningitis exhibited ADHD-like behaviors later in life and neural hyperactivation in the nucleus accumbens due to the increase in dopaminergic inputs induced by macrophages. RNA-sequencing revealed macrophages in carrageenan-treated mice express increased level of Semaphorin 4A (Sema4A), and treatment with a Sema4A neutralizing antibody prevented ADHD-like behaviors after carrageenan treatment. In addition, Sema4A concentration was increased in the cerebrospinal fluid of patients with meningitis, and Sema4A promoted dopaminergic synapse formation in human neurons. Collectively, these findings suggest macrophages increase dopaminergic inputs by producing Sema4A, which is a critical factor in the development of neonatal meningitis-induced ADHD-like behaviors.

Abstract

The productivity and sustainability of many tropical agricultural systems must be increased to meet sustainability requirements to prevent deforestation of new non-agricultural areas. The availability and uptake efficiency of crop nutrients are fundamental considerations for any attempt to achieve this increase in productivity. We hypothesised that leguminous residues modify soil attributes through chemical and biological changes that affect plant growth and the long-term sustainability of agroecosystems in humid tropical regions. The present study aimed to determine the effects of leguminous biomass on the variations of soil organic matter fractions and soil basic cation contents and to evaluate the effects of these changes on the proportions of soil phosphorus (P) in different pools in a cropping system. A randomised block design with four replications and the following treatments was used for the modified alley cropping: Leucaena + Clitoria (L + C); Leucaena + Gliricidia (L + G); Leucaena + Acacia (L + A); Gliricidia + Acacia (G + A); Gliricidia + Clitoria (G + C), and no residues (NR). Our results confirmed the positive effects of the long-term application of leguminous biomass on those soil attributes that are the main drivers of the sustainability of tropical agroecosystems. However, such effects can differ depending on the biomass quality used. Indeed, the biomass of lower quality was more efficient in redirecting the fluxes of P towards the organic P pool, decreasing the less available Pi fractions. While the use of high-quality biomass from leucaena + gliricidia was superior to increase the stabilised carbon fraction in association with basic cations content. Ultimately, it can be concluded that to prevent cultivated land degradation and to avoid deforestation of new areas in the Amazonian periphery, production and application of high-quality biomass is an adequate strategy.
