CAUSES OF THERMAL SUFFOSION ATTENUATION ON THE BESTYAKH TERRACE OF THE LENA RIVER, CENTRAL YAKUTIA
Authors: Gagarin L. A. , Olenchenko V. V. , Pavlova N. A. 
Published: April 2024

This paper presents the results of thermal suffosion study in the Ulakhan-Taryn Creek valley, Central Yakutia, where intrapermafrost groundwater is discharged. Interpretation of satellite images and analysis of field data from landscape surveys, electrical resistivity tomography studies and ground temperature observations were used to determine the factors contributing to the attenuation of thermal suffosion in sandy deposits of the IV (Bestyakh) terrace of the Lena River. Successional stages of revegetation in the accumulation zones of sands washed off by subsurface flow were examined. Vegetation succession was found to modify geocryological conditions in the groundwater discharge area, sometimes leading to its complete freezing. Conditions favorable both for permafrost aggradation and degradation may develop, depending on the landscape type. Ground temperature data indicate that the active layer thickness in sands at a thermal suffosion site covered by sparse pine forest is 3.5 m, while the mean annual permafrost temperature at the depth of zero annual amplitude is –0.2°С. In 2014, a subaerial talik began to form at this site, the bottom of which lowered from 3.5 m down to 6.0 m. At a larch site with tussocks, the active layer thickness is within 0.5–0.8 m and the mean annual permafrost temperature is about –2.0°С. An ERT survey provided information on the current permafrost and groundwater conditions, where groundwater discharge has ceased. A scenario is proposed describing the changes in the discharge area caused by permafrost disturbance above an aquifer. Formation of an underground cavity and collapse of the overlying permafrost layer resulting in characteristic depressions and sinkholes at the surface promote ground freezing in the discharge zone. Mechanical blocking the flow paths reduces the flow velocity promoting the restoration of permafrost and cutting off the area of soil removal by thermal suffosion. Further on, this attenuates the thermal suffosion. Its active phase can shift spatially due to thawing the pore ice in the permafrost in contact with the confined aquifer, widening soil voids and forming new flow pathways. Thus, attenuation of thermal suffosion on the Bestyakh Terrace of the Lena River results from the combination of internal (impeded flow) and external (vegetation succession) factors.

Published: April 2024

Studies have been conducted on the variations of ambient noise recorded by broadband and short-period seismic stations in the area of South Baikal before and after the large December 9, 2020 Kudara earthquake with Mw = 5.6. 10 days before the earthquake, there was a gradual increase of oscillation amplitudes in the frequency range from 0.01 to 0.1 Hz, with an increasing background observed also during 4 days after the main shock (period from 01.12.2020 to 13.01.2021). The maximum amplitude increase is 19.5 against the background. During this time, there were recorded 48 aftershocks. The analysis of direction of particle motion in seismic waves over the reporting period showed an abrupt change in the orientation of oscillations, which is fully consistent with the azimuth for the main shock epicenter. The analysis of seismograms over the next period (from December 13) did not show similar effects in the ambient noise field. Apparently, the ambient noise field reflected the process of slow faulting before the earthquake and after the main shock with subsequent attenuation.
NEW DATA ON THE AGE OF MAGMATIC ROCKS OF THE ALPHA-MENDELEEV RISE (ARCTIC OCEAN): RESULTS OF ISOTOPIC U/Pb DATING OF ZIRCONS
Authors: Skolotnev S. G. , Fedonkin M. A. , Korniychuk A. V. 
Published: April 2024

The age of magmatic rocks of the basic composition sampled at the Alpha-Mendeleev Rise in the Arctic Ocean with the help of a research submarine was studied, based on the measurement of the U/Pb age of zircons separated from them. Early Cretaceous rocks of the moderately alkaline series, formed at the turn of 112 million years, are most common on the Rise. These rocks contain a large number of ancient xenogenic zircons, the age analysis of which shows that the subalkaline melts interacted with the crust at two levels: with the horizon of Early Cretaceous sandstones and with rocks of the Late Archean crystalline basement with an age of 2675.1 ± 11.6 million years. They also contain a small number of younger zircons with an age of 83–87 million years, which probably arose during the recrystallization of Early Cretaceous zircons under the influence of Late Cretaceous magmatism.

The paper analyses the methods of designing wing mechanisation for transport category aircraft. The wing layout with the placement of wing mechanisation means on the leading and trailing edges of the wing is analysed. Specific requirements for wing mechanisation units are considered. The analysis takes into account the requirements of aircraft operation, which provide easy access to inspect the mechanisation units and their attachment mechanisms. The need for constant monitoring of the synchronous operation of all mechanisation sections and ensuring their smooth movement is emphasised. The design of any type of mechanisation means involves the simultaneous solution of a number of development tasks: kinematic scheme, installation and control system, support structure and the device itself. In most cases, the drive mechanisms are also developed. The design of a new aircraft is a multi-stage iterative process that includes external design, development of a technical proposal, preliminary design, detailed design, production of prototypes, ground and flight tests, which determine the actual characteristics of the aircraft and the degree of its compliance with the technical specifications. Consider the advantages created by wing mechanisation equipment. The mechanisation of the AN-140 is considered as a representative of aircraft whose wings have trailing edge mechanisation but no leading edge mechanisation. The mechanisation of the AN-74 is also considered as a representative of aircraft that use two- or three-slotted retractable flaps, winglets or nose shields of large curvature over the entire wing span. The design technologies in integrated computer information systems are characterised, which allow to build a single process of computer modelling and engineering analysis and to conduct multivariate studies to select optimal design solutions in a sufficiently short time. A block diagram of the process of detailed design of flaps is proposed.

Authors: Tiulieniev S. A. 
Published: April 2024

Establishment and development of the economic security of the state requires taking effective measures to counteract and minimise the negative impact of criminal offences that encroach on public relations in the areas of economic activity, legal activities of business entities, professional activities of public administration entities, etc. Among such criminal offences, much attention is paid to those with signs of raiding, i.e. those related to the unlawful takeover and seizure of property, assets of enterprises, institutions, organisations, corporate rights to them and other resources, encroachment on the rights of owners or authorised persons of business entities of various forms of ownership, etc. An important role in proving and clarifying the circumstances to be proved in these criminal offences is played by expert opinions. Given the insufficient elaboration of the issues related to the appointment of forensic examinations in the course of investigation of criminal offences related to raiding, the purpose of the article is to define the range of forensic examinations which are appointed during the pre-trial investigation of the latter, and to clarify the specifics of their appointment. To achieve this goal, the article uses a range of general scientific methods, as well as some philosophical and special research methods, in particular, analysis, synthesis, systemic and structural method, forecasting method and dialectical method.
Based on the results of the analysis of the investigative and judicial practice of investigating criminal offences related to raiding, it has been found that the typical expert examinations which are appointed during their investigation are forensic technical examination of a document, forensic economic examination, and forensic handwriting examination. It has been generalised that they are appointed in every second criminal proceeding of the type under study.
The author identifies the factors which should be taken into account when deciding on the necessity and expediency of appointing a forensic examination during a pre-trial investigation. The article also identifies the mistakes made by the prosecution when appointing the specified types of qualified specialised investigations. Given the nature of raiders’ actions, the processes taking place in society and in the professional activities of individual participants in social relations, the author outlines the prospects for further scientific research.

Published: April 2024

BackgroundIn the face of continued growth in the elderly population, the need to understand and combat age-related cardiac decline becomes even more urgent, requiring us to uncover new pathological and cardioprotective pathways.MethodsWe obtained the aging-related genes of heart failure through WGCNA and CellAge database. We elucidated the biological functions and signaling pathways involved in heart failure and aging through GO and KEGG enrichment analysis. We used three machine learning algorithms: LASSO, RF and SVM-RFE to further screen the aging-related genes of heart failure, and fitted and verified them through a variety of machine learning algorithms. We searched for drugs to treat age-related heart failure through the DSigDB database. Finally, We use CIBERSORT to complete immune infiltration analysis of aging samples.ResultsWe obtained 57 up-regulated and 195 down-regulated aging-related genes in heart failure through WGCNA and CellAge databases. GO and KEGG enrichment analysis showed that aging-related genes are mainly involved in mechanisms such as Cellular senescence and Cell cycle. We further screened aging-related genes through machine learning and obtained 14 key genes. We verified the results on the test set and 2 external validation sets using 15 machine learning algorithm models and 207 combinations, and the highest accuracy was 0.911. Through screening of the DSigDB database, we believe that rimonabant and lovastatin have the potential to delay aging and protect the heart. The results of immune infiltration analysis showed that there were significant differences between Macrophages M2 and T cells CD8 in aging myocardium.ConclusionWe identified aging signature genes and potential therapeutic drugs for heart failure through bioinformatics and multiple machine learning algorithms, providing new ideas for studying the mechanism and treatment of age-related cardiac decline.

BackgroundThe effect of total intravenous anaesthesia (TIVA) and inhalation anaesthesia (IA) on the prognosis of patients with colorectal cancer after resection is controversial. This study aimed to explore the effects of different anaesthesia methods on the postoperative prognosis of colorectal cancer.MethodsPubMed, Embase and Cochrane Library databases were searched for relevant literature from each database’s inception until 18 November 2023. The literature topic was to compare the effects of TIVA and IA on the prognosis of patients undergoing colorectal cancer resection.ResultsSix studies were selected for meta-analysis. The studies involved 111043 patients, with a trial size of 1001–88184 people. A statistically significant difference was observed in the overall survival (OS) between colorectal cancer patients administered TIVA and IA (hazard ratio [HR], 0.83; 95% confidence interval [CI], 0.70–0.99), but none in recurrence-free survival (RFS) (HR, 0.99; 95% CI, 0.90–1.08). In the subgroup analysis of OS, no statistically significant difference was observed between colorectal cancer patients administered TIVA and IA in Asia (HR, 0.77; 95% CI, 0.57–1.05), and not in Europe (HR, 0.99; 95% CI, 0.93–1.06). Regarding tumour location, no significant association was found between TIVA and IA in the colon, rectum and colorectum ((HR, 0.70; 95% CI, 0.38–1.28), (HR, 0.95; 95% CI, 0.83–1.08) and (HR, 0.99; 95% CI, 0.93–1.06), respectively).ConclusionOS differed significantly between patients administered TIVA and IA when undergoing colorectal cancer resection, but no difference was observed in RFS. The prognostic effects of TIVA and IA differed.Systematic review registrationhttps://www.crd.york.ac.uk/prospero/display_record.php?ID=CRD42023453185, identifier CRD42023453185.
Human–object interaction, connectedness with nature, and life satisfaction: a cross-sectional study
Authors: Kamide Hiroko , Arai Tatsuo 
Published: April 2024

IntroductionThis study aimed to elucidate the relationship between interactions with everyday objects (e.g., stationery, clothing, and tools) and one’s connectedness with nature, environmentally conscious behavior, and life satisfaction. While previous research has predominantly explored the link between awareness of and behavior toward nature with direct education and experience related to the natural environment, we focused on the origins of the objects that surround us, which are inherently derived from nature.MethodsWe conducted an online survey with 1,102 Japanese participants, who completed an object–interaction measure assessing the two dimensions of care and learning, and measures of connectedness with nature, pro-environmental behavior, and life satisfaction.ResultsInteractions with everyday objects involving care and learning were significantly associated with a sense of connectedness with nature, pro-environmental behavior, and life satisfaction.DiscussionThe study highlights that interactions with everyday artifacts are not isolated experiences but are related to broader awareness of and behavior toward the natural world, and with individual life satisfaction. Hence, environmental awareness and actions can extend beyond direct environmental experiences and encompass daily interactions with objects. Future research could examine how cultural factors shape the relationship between human–object interactions, connection with nature, environmentally conscious behavior, and life satisfaction.

Published: April 2024

BackgroundExposure to high levels of heavy metals has been widely recognized as an important risk factor for metabolic syndrome (MetS). The main purpose of this study is to assess the associations between the level of heavy metal exposure and Mets using machine learning (ML) method.MethodsThe data used in this study are from the national health and nutrition examination survey 2003–2018. According to the demographic information and heavy metal exposure level of participants, a total of 22 variables were included. Lasso was used to screen out the key variables, and 9 commonly used ML models were selected to establish the associations with the 5-fold cross validation method. Finally, we choose the SHapley Additive exPlanations (SHAP) method to explain the prediction results of Adaboost model.Results11,667 eligible individuals were randomly divided into two groups to train and verify the prediction model. Through lasso, characteristic variables were selected from 24 variables as predictors. The AUC (area under curve) of the models selected in this study were all greater than 0.7, and AdaBoost was the best model. The AUC value of AdaBoost was 0.807, the accuracy was 0.720, and the sensitivity was 0.792. It is noteworthy that higher levels of cadmium, body mass index, cesium, being female, and increasing age were associated with an increased probability of MetS. Conversely, lower levels of cobalt and molybdenum were linked to a decrease in the estimated probability of MetS.ConclusionOur study highlights the AdaBoost model proved to be highly effective, precise, and resilient in detecting a correlation between exposure to heavy metals and MetS. Through the use of interpretable methods, we identified cadmium, molybdenum, cobalt, cesium, uranium, and barium as prominent contributors within the predictive model.

Spartina alterniflora (S. alterniflora) has grown rapidly in China since its introduction in 1979, showing the trend of alien species invasion, which has seriously affected the ecosystem balance of coastal wetlands. The temporal and spatial expansion law of S. alterniflora can be obtained through remote sensing monitoring, which can provide a reference and basis for S. alterniflora management. This paper presents a method for extracting and mapping S. alterniflora based on phenological characteristics. The coastal areas of the Yangtze River Delta Urban Agglomeration are selected as the research area, and the Landsat time series data from 1990 to 2022 on the Google Earth Engine (GEE) platform are used to support the experiment in this paper. Firstly, the possible growing area of S. alterniflora was extracted using the normalized differential moisture index (NDMI), normalized differential vegetation index (NDVI), and normalized differential water index (NDWI); Then, the time series curve characterizing the phenological characteristics of vegetation was constructed using the vegetation index to determine the difference phase of phenological characteristics between S. alterniflora and other vegetation. Finally, a decision tree was constructed based on the phenological feature difference phase data to extract S. alterniflora, and it is applied to the analysis of temporal and spatial changes of S. alterniflora in the study area from 1990 to 2022. The results show that the area of S. alterniflora increased from ~1426 ha in 1990 to ~44,508 ha in 2022. However, the area of S. alterniflora began to show negative growth in 2015 due to the construction of nature reserves and ecological management. The results of correlation analysis showed that the growth of C. japonicum was significantly affected by temperature stress and weakly affected by precipitation. This study verified that Landsat time series images can effectively extract vegetation phenological information, which has strong feasibility for extraction and dynamic monitoring of S. alterniflora and provides technical support for the management and monitoring of invasive plants in coastal wetlands.
