Published: April 2024

В настоящей работе рассматривается вопрос организации хранения корпусов поэтических текстов в информационных аналитических системах с учетом специфики структуры поэтического текста. В Федеральном исследовательском центре информационных и вычислительных технологий разработана и реализована оригинальная программная система автоматизированного комплексного анализа русских поэтических текстов. Информационная система, как соответствующий компонент программной системы, объединяет разнородную информацию о результатах анализа поэтических текстов. Поэтический текст – структура иерархичная по своей языковой природе, что необходимо учитывать при разработке информационных систем, предназначенных для хранения и обработки текстов на естественном языке. Вопрос иерархии текста равнозначно важен для процесса его анализа и для хранения корпусов текстов. Хранилище текстов является, как правило, центральным компонентом информационных аналитических систем и либо проектируется как база данных, либо представляет собой неструктурированный набор данных. Для экспертов-филологов, работающих с системой, принципиально качество данных, что наиболее достижимо при работе с правильно организованным материалом. В результате концептуального проектирования хранилища корпусов поэтических текстов, с учетом специфики объектов предметной области, обосновано целесообразное использование двух систем хранения и поиска данных: реляционной базы данных для хранения связей между объектами в системе, а также объектов, не являющихся частью корпуса, и хранилища файлов с инструментом полнотекстового поиска в корпусе текстов, что повышает качество анализа текстов и расширяет возможности применения системы в целом.

Assessing improvements in global ocean pCO2 machine learning reconstructions with Southern Ocean autonomous sampling

Published: April 2024

Abstract. The Southern Ocean plays an important role in the exchange of carbon between the atmosphere and oceans and is a critical region for the ocean uptake of anthropogenic CO2. However, estimates of the Southern Ocean air–sea CO2 flux are highly uncertain due to limited data coverage. Increased sampling in winter and across meridional gradients in the Southern Ocean may improve machine learning (ML) reconstructions of global surface ocean pCO2. Here, we use a large ensemble test bed (LET) of Earth system models and the “pCO2-Residual” reconstruction method to assess improvements in pCO2 reconstruction fidelity that could be achieved with additional autonomous sampling in the Southern Ocean added to existing Surface Ocean CO2 Atlas (SOCAT) observations. The LET allows for a robust evaluation of the skill of pCO2 reconstructions in space and time through comparison to “model truth”. With only SOCAT sampling, Southern Ocean and global pCO2 are overestimated, and thus the ocean carbon sink is underestimated. Incorporating uncrewed surface vehicle (USV) sampling increases the spatial and seasonal coverage of observations within the Southern Ocean, leading to a decrease in the overestimation of pCO2. A modest number of additional observations in Southern Hemisphere winter and across meridional gradients in the Southern Ocean leads to an improvement in reconstruction bias and root-mean-squared error (RMSE) of as much as 86 % and 16 %, respectively, as compared to SOCAT sampling alone. Lastly, the large decadal variability of air–sea CO2 fluxes shown by SOCAT-only sampling may be partially attributable to undersampling of the Southern Ocean.

Abstract. We present direct measurements of BVOC-induced nitrate radical (NO3) reactivity (kVOC) through the diel cycle in the suburban, temperate forest of Rambouillet near Paris (France). The data were obtained in a six-week summer period in 2022 as part of the ACROSS campaign (Atmospheric ChemistRy Of the Suburban foreSt). kVOC was measured in a small (700 m2) clearing mainly at a height of 5.5 m above ground level, but also at 40 m (for 5 days/nights). At nighttime, mean values of knightVOC(5.5 m) = (0.24 ± 0.27) s-1 and knightVOC(40 m) = (0.016 ± 0.007) s-1 indicate a significant vertical gradient and low NO3 reactivity above the canopy, whereas knightVOC(5.5 m) showed peak values of up to 2 s-1 close to the ground. The strong vertical gradient in NO3 reactivity could be confirmed by measurements between 0 and 24 m on one particular night characterised by a strong temperature inversion, and is a result of the decoupling of air masses aloft from the ground- and canopy-level sources of BVOCs (and NO). No strong vertical gradient was observed in the mean daytime NO3 reactivity with kdayVOC(5.5 m) = (0.12 ± 0.04) s-1 for the entire campaign and kdayVOC(40 m) = (0.07 ± 0.02) s-1 during the 5-day period. Within the clearing, the fractional contribution of VOCs to the total NO3 loss rate (LNO3, determined by photolysis, reaction with NO and VOCs) was 80–90 % during the night and ~50 % during the day. In terms of chemical losses of α-pinene below canopy height in the clearing, we find that at nighttime OH and O3 dominate with NO3 contributing “only” 17 %, which decreases further to 8.5 % during the day. Based on OH, O3 and NO3 concentrations, the chemical lifetime of BVOCs at noon is about one hour and is likely to be longer than timescales of transport out of the canopy (typically in the order of minutes), thus significantly reducing the importance of daytime, in-canopy processing. Clearly, in forested regions where sufficient NOX is available, the role of NO3 and OH as initiators of BVOC oxidation are not strictly limited to the night and to the day, respectively, as often implied in e.g. atmospheric chemistry text-books.

Abstract. Due to the unbalanced emission reductions in ozone precursors in recent years, ozone trends and the causes of their variations in eastern China remain insufficiently understood. To explore the factors controlling ozone trends in eastern China, the long–term ozone precursors observation experiment was conducted. Combined with the satellite and surface measurements, the trend of low, typical and peak ozone concentrations in eastern China was evaluated in detail. Observation results show that the surface peak ozone concentrations significantly decreased (-0.5 % per year) while low ozone concentrations increased (0.3 % per year) in eastern China during May–September 2017–2022. The underlying cause of surface ozone trends in eastern China is anthropogenic emissions (~85 %), and the contribution of meteorological factors is not significant (~15 %). Ozone formation sensitivity is in VOC–limited regime or transition regime during periods (8:00–11:00) of sharp increases in ozone concentrations, and it is usually in NOx–limited regime when the ozone concentration reaches its peak (~14:00). Substantial reductions in nitrogen oxides (NOx) emissions have diametrically opposed effects on peak (decreasing) and low (increasing) ozone concentrations, and reducing volatile organic compounds (VOCs) concentrations is the key to reversing the current high ozone level situation in eastern China. In addition, there are obvious interannual variations of surface O3 formation sensitivity on spatial scales through long–term satellite observations, in which area proportion of VOC–limited regime is decreasing while the area proportion of NOx–limited regime is increasing. Our results highlight the positive impact of NOx reduction in controlling peak O3 levels, and regular changes in the ozone formation sensitivity throughout the day should be taken into account when formulating ozone control policies.

Published: April 2024

Abstract. Haiti, a Caribbean country, is highly vulnerable to hydroclimatic hazards due to heavy rainfall, which is partly linked to tropical cyclones. Additionally, its steep slopes generate flash floods, particularly in small catchments. Moreover, the hydrology of this region remains poorly understood and understudied. Unfortunately, there is no accessible database for the scientific community to use in this country. To fill this gap, hydroclimatic data were collected to create the first historical database in Haiti. This database, called Simbi (guardian of rivers, freshwater, and rain in Haitian mythology), includes 156 monthly rainfall series over the period 1905–2005, 59 daily rainfall series over the period 1920–1940, 70 daily streamflow series, and 23 monthly temperature series, not necessarily continuous, over the period 1920–1940. It also provides simulated streamflow series over the period 1920–1940 using the GR2M and GR4J rainfall–runoff models for 24 catchments and 49 attributes covering a wide range of topographic, climatic, geological, land use, hydrogeological, and hydrological signature indices. Simbi is the first open-access hydro-meteorological dataset for Haiti and will contribute to a better knowledge of hydrological risk in Haiti. Several sources of uncertainty associated with Simbi are acknowledged, including data quality (historical data), digitisation of paper archives, identification of relevant rain gauges, and rainfall–runoff models. It is important to consider these uncertainties when using Simbi. The database will be regularly updated to include additional historical data that will be digitised in the future. It will thus contribute toward better knowledge of the hydrology of Haitian catchments and will enable the implementation of various hydrological calculations useful for designing structures or flow forecasting. Simbi is an open-access database and is available for download at https://doi.org/10.23708/02POK6 (Bathelemy et al., 2023).
Development and preliminary validation of a land surface image assimilation system based on the Common Land Model

Published: April 2024

Abstract. Data assimilation is an essential approach to improve the predictions of land surface models. Due to the characteristics of single-column models, assimilation of land surface information has mostly focused on improving the assimilation of single-point variables. However, land surface variables affect short-term climate more through large-scale anomalous forcing, so it is indispensable to pay attention to the accuracy of the anomalous spatial structure of land surface variables. In this study, a land surface image assimilation system capable of optimizing the spatial structure of the background field is constructed by introducing the curvelet analysis method and taking the similarity of image structure as a weak constraint. The fifth-generation ECMWF Reanalysis – Land (ERA5-Land) soil moisture reanalysis data are used as ideal observation for the preliminary effectiveness validation of the image assimilation system. The results show that the new image assimilation system is able to absorb the spatial-structure information of the observed data well and has a remarkable ability to adjust the spatial structure of soil moisture in the land model. The spatial correlation coefficient between the model surface soil moisture and observation increased from 0.39 to about 0.67 after assimilation. By assimilating the surface soil moisture data and combining these with the model physical processes, the image assimilation system can also gradually improve the spatial structure of soil moisture content at a depth of 7–28 cm, with the spatial correlation coefficient between the model soil moisture and observation increased from 0.35 to about 0.57. The forecast results show that the positive assimilation effect could be maintained for more than 30 d. The results of this study adequately demonstrate the application potential of image assimilation system in short-term climate prediction.
Developing meshing workflows in Gmsh v4.11 for the geologic uncertainty assessment of high-temperature aquifer thermal energy storage

Published: April 2024

Abstract. Evaluating uncertainties of geological features on fluid temperature and pressure changes in a reservoir plays a crucial role in the safe and sustainable operation of high-temperature aquifer thermal energy storage (HT-ATES). This study introduces a new automated surface fitting function in the Python API (application programming interface) of Gmsh (v4.11) to simulate the impacts of structural barriers and variations of the reservoir geometries on thermohydraulic behaviour in heat storage applications. These structural features cannot always be detected by geophysical exploration but can be present due to geological complexities. A Python workflow is developed to implement an automated mesh generation routine for various geological scenarios. This way, complex geological models and their inherent uncertainties are transferred into reservoir simulations. The developed meshing workflow is applied to two case studies: (1) Greater Geneva Basin with the Upper Jurassic (“Malm”) limestone reservoir and (2) the 5° eastward-tilted DeepStor sandstone reservoir in the Upper Rhine Graben with a uniform thickness of 10 m. In the Greater Geneva Basin example, the top and bottom surfaces of the reservoir are randomly varied by ± 10 and ± 15 m, generating a total variation of up to 25 % from the initially assumed 100 m reservoir thickness. The injected heat plume in this limestone reservoir is independent of the reservoir geometry variation, indicating the limited propagation of the induced thermal signal. In the DeepStor reservoir, a vertical sub-seismic fault juxtaposing the permeable sandstone layers against low permeable clay-marl units is added to the base case model. The fault is located in distances varying from 4 to 118 m to the well to quantify the possible thermohydraulic response within the model. The variation in the distance between the fault and the well resulted in an insignificant change in the thermal recovery (∼ 1.5 %) but up to a ∼ 10.0 % pressure increase for the (shortest) distance of 4 m from the injection well. Modelling the pressure and temperature distribution in the 5° tilted reservoir, with a well placed in the centre of the model, reveals that heat tends to accumulate in the updip direction, while pressure increases in the downdip direction.

Abstract. Soil properties and their associated hydro-physical parameters represent a significant source of uncertainty in Land Surface Models (LSMs) with consequent effects on simulated sub-surface thermal and moisture characteristics, surface energy exchanges and turbulent fluxes. These effects can result in large model differences particularly during extreme events. Typical of many model based approaches, spatial soil information such as location, extent and depth of textural classes are derived from coarse scale soil information and employed largely due to their ready availability rather than suitability. However, the use of a particular spatial soil dataset has important consequences for many of the processes simulated within a LSM. This study investigates NOAH-MP model uncertainty in simulating soil moisture (expressed as a ratio of water to soil volume, m3 m-3) and soil temperature changes associated with two widely used global soil databases (STATSGO and SOILGRIDS) across the Island of Ireland. Both soil datasets produced a significant dry bias in loam soils, up to 0.15 m3 m-3 in a wet period and 0.10 m3 m-3 in a dry period. The spatial disparities between STATSGO and SOILGRIDS also influenced the regional soil hydrothermal changes and extremes. SOILGRIDS was found to intensify drought characteristics – shifting low/moderate drought areas into extreme/exceptional during dry periods – relative to STATSGO. Our results demonstrate that the coarse STATSGO performs as good as the fine-scale SOILGRIDS soil database. However, the results underscore the need to develop detailed regionally-derived soil texture characteristics, and for better representations of soil physics in LSMs to improve operational modeling and forecasting of hydrological processes and extremes.

Research on the Integration of Educational Resources in Higher Education Administration
Authors: Li Lin
Published: April 2024

In order to improve the integration of higher education resources, local governments should strengthen the administrative management of higher education and propose measures to promote social governance. Therefore, from the perspective of local autonomy, this paper puts forward the following hypotheses about local government behavior and public policy adjustment: whether local autonomy affects the adjustment of higher education policy, whether the role of local intervention policy and legal improvement overlaps, whether the impact on resource integration is perfect, whether the public supervision mechanism is perfect, whether the public plays a role in promoting the integration of educational resources, and whether local laws and regulations have an impact on the integration of educational resources, the educational environment, and the level of local governance. The results show that the policy intervention of local governments and the improvement of laws and regulations have a great impact on the integration of educational resources, which can optimize the educational structure and form a good educational environment, which is the direct factor of the integration of educational resources. Therefore, local governments should strengthen the introduction of intervention policies, improve laws and regulations, and guide the public to participate in the integration of education.
Role of preservation methods using deep-freezing and liquid nitrogen in bone allograft characteristics: An in vitro study
Authors: Lisan Rizal A. , Mahyudin Ferdiansyah , Edward Mouli , Buwana Dewan S.
Published: April 2024

Bone grafting has emerged as a key solution in bone defect management such as allograft, graft of bone from another individual. However, bone allografts usually undergo rigorous preparation to eliminate immune-triggering elements. The deep-freezing methods may delay graft use, while cryopreservation using liquid nitrogen allows rapid freezing but may alter graft characteristics. The aim of this study was to investigate the post-preservation changes in bone allograft characteristics and to compare the effectiveness of deep-freezing and liquid nitrogen methods using animal model. An experimental study using a post-test only control group design was conducted. Fresh-frozen femoral cortical bone was obtained from male New Zealand white rabbits. Preservation by deep-freezing involved placing bone samples in a -80°C freezer for 30 days. For liquid nitrogen preservation, bone grafts were immersed in liquid nitrogen for 20 min, followed by a 15-min rest at room temperature and a final immersion in 0.9% sodium chloride at 30°C for 15 min. Bone samples then underwent evaluation of cell viability, compression, and bending tests. Cell viability test employed the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay and the compression and bending tests used the Universal Testing Machine (UTM). Independent Student t-test or Mann-Whitney U test were used to compare the methods as appropriate. Our study found that the use of deep-freezing and liquid nitrogen resulted in similar outcomes for cell viability, compression, and bending tests, with p-values of 0.302, 0.745, and 0.512, respectively. Further exploration with larger sample sizes may help to optimize the methods for specific applications.
The Decision to Install a Rooftop Photovoltaic System by a Small Business: A Case Study
Authors: Schwartz Demitrius , Batabyal Amitrajeet A.
Published: April 2024

The potential of rooftop solar power has been identified as a main driver of clean energy adoption in an urban environment. While residential solar projects have lower capacity than commercial systems, residential solar represents most of the installation base for rooftop solar projects. Rooftop solar adoption in the commercial market lags behind residential solar installation. To better understand why this is the case, we conduct a case study of a small manufacturing firm. Based on the firm’s energy demand and the physical attributes of its location, we study a 25-kilowatt solar array using the National Renewable Energy Laboratory’s (NREL) System Advisor Model (SAM). Our empirical study evaluates the economic prospects of a rooftop solar installation project for the firm under study. This analysis sheds light on the financial ramifications of the adoption of solar panels by small, commercial firms in New York state.

Hybrid fault tolerance in distributed in-memory storage systems
Authors: Gong Zheng , Wu Si , Xu Yinlong ,   School of Computer Science and Technology, University of Science and Technology of China, Hefei 230027, China
Published: April 2024

An in-memory storage system provides submillisecond latency and improves the concurrency of user applications by caching data into memory from external storage. Fault tolerance of in-memory storage systems is essential, as the loss of cached data requires access to data from external storage, which evidently increases the response latency. Typically, replication and erasure code (EC) are two fault-tolerant schemes that pose different trade-offs between access performance and storage usage. To help make the best performance and space trade-off, we design ElasticMem, a hybrid fault-tolerant distributed in-memory storage system that supports elastic redundancy transition to dynamically change the fault-tolerant scheme. ElasticMem exploits a novel EC-oriented replication (EOR) that carefully designs the data placement of replication according to the future data layout of EC to enhance the I/O efficiency of redundancy transition. ElasticMem solves the consistency problem caused by concurrent data accesses via a lightweight table-based scheme combined with data bypassing. It detects corelated read and write requests and serves subsequent read requests with local data. We implement a prototype that realizes ElasticMem based on Memcached. Experiments show that ElasticMem remarkably reduces the time of redundancy transition, the overall latency of corelated concurrent data accesses, and the latency of single data access among them.
PUDING KACANG HIJAU ‘PUJO’ SEBAGAI UPAYA PENCEGAHAN STUNTING
Authors: Dekawaty Ayu
Published: April 2024

Stunting merupakan gangguan tumbuh kembang yang dialami anak akibat gizi buruk, infeksi berulang, dan stimulasi psikososial yang tidak memadai. Gizi yang tidak seimbang pada anak mengakibatkan gangguan pertumbuhan dan perkembangan kedepannya. Angka stunting di Indonesia ditargetkan turun dibawah 20% sehingga mampu mencapai target WHO. Untuk mencapai target tersebut diperlukan upaya bersama, salah satunya dimulai dari unit terkecil dalam masyarakat, yakni keluarga. Berdasarkan data yang didapat dari pelaksanaan Praktik Kerja Lapangan Terpadu (PKLT) yang dilakukan oleh mahasiswa IKesT Muhammadiyah Palembang dengan isntrumen kuesioner, wawancara, dan pengamatan ditemukan data mengenai potensial peningkatan kejadian stunting dengan data:61% responden tidak memenuhi kebutuhan ‘isi piringku’, masyarakat dominan memberikan makanan dengan kandungan karboidrat, dan tidak memperhatikan keberagaman jenis makanan. Hasil data sekunder dari Puskesmas didapatkan 3 kasus stunting di wilayah tersebut. Untuk mengatasi permasalahan tersebut pengabdi melakukan kegiatan yang bertujuan untuk menurunkan potensi peningkatan angka stunting dengan upaya memberikan penyuluhan tentang gizi seimbang ‘isi piringku’ serta pengembangan produk inovatif pembuatan dan pembagian puding kacang hijau ‘PUJO’ pada balita dan anak. Setelah dilakukan kegiatan, evaluasi dilakukan dengan tanya jawab dan observasi. Masyarakat dapat menjawab pertanyaan tentang kebutuhan gizi pada anak serta alternatif makanan sehat yang dapat diberikan pada bayi dan anak, seperti puding kacang hijau. Anak-anak menyukai dan menghabiskan puding yang diberikan. Program seperti ini diharapkan dapat menjadi program rutin yang selanjutnya dapat dilakukan dalam upaya pencegahan stunting.

Latar Belakang: Gizi seimbang adalah susunan pangan harian yang mengandung zat gizi dalam jenis dan jumlah yang sesuai dengan apa yang dibutuhkan tubuh. Gizi seimbang diperlukan anak sekolah untuk masa pertumbuhan. Sebagian besar anak sekolah dasar belum mengetahui gizi seimbang karena mereka masih terpaku pada konsep empat sehat lima sempurna yang mana mereka berpendapat bahwa makan nasi harus lebih banyak daripada lauk pauk dan sayuran, juga sebagian anak menyatakan bahwa minum susu saja sudah cukup dan tidak memerlukan makanan lainnya. Tujuan: untuk meningkatkan pengetahuan anak-anak sekolah MI Al-Kautsar di Kelurahan 13 Ulu, Kecamatan Seberang Ulu II di kota Palembang. Metode: Penyuluhan ini dilakukan dengan menggunakan media powerpoint dengan metode ceramah dan tanya jawab. Hasil: Hasil dari kegiatan pengabdian masyarakat ini yaitu pengetahuan siswa MI Al-Kautsar mengenai gizi seimbang meningkat. Simpulan: Edukasi kesehatan dilakukan untuk meningkatkan pengetahuan yang akhirnya akan mempengaruhi sikap dan tindakan anak-anak untuk memperbaiki kebiasaan hidup sesuai dengan anjuran gizi seimbang dan mengetahui porsi makanan apa saja yang ada di isi piringku.

Authors: Anggarini Inge Anggi
Published: April 2024

Changes in the postpartum period require a lot of adjustments so they can cause both psychological and physical disorders. Depression in postpartum mothers tends to be invisible but has a negative impact. Mothers who cannot adapt to the critical postpartum period can experience psychological disorders. This disorder is common in women during pregnancy and postpartum but often goes undiagnosed and untreated.. Maternal depressive symptoms affect the mother's emotional and cognitive ability to interact with the baby and family, especially in conditions of long-term depression. Education or counseling can be carried out to increase knowledge or understanding of postpartum mothers. The community service method is in the form of education or counseling with the title Early Detection of Depression in Postpartum Mothers. This activity will be carried out in January-February 2024 at PMB Herasdiana Palembang. During this 2 month period, several stages of preparation were carried out and coordinated with related parties and provided education to mothers at PMB Herasdiana Palembang.

The main aim of this work is to find out LULC classes for the Indore region. For the last seven years, Indore has been crowned the cleanest city in India according to the latest ranking of 2023. In the Indian state of Madhya Pradesh, the city and district of Indore are situated on the southern edge of the Malwa plateau. The municipalities of the Indore district majorly cover Manpur, Depalpur, Goutampura, Mhow, Hatod, Betma, Rau and Sanwer, with an area of approximately 3900 square kilometers. In contrast, Indore covers a land area of approximately 530 square kilometres. It is in charge of the nation’s slow but steady industrialization and population growth found in the last three decades. The city was much smaller and had a far smaller population thirty years ago. However, to evaluate the changes and decide on Indore city's future planning, Indore has taken over responsibility for the city's economic activities in recent years. New appropriate patterns should be recommended based on local factors like topography characteristics. The satellite image with multiple spectrums was used for the investigation. ArcGIS is based on pixel-by-pixel supervised classification using the maximum likelihood approach of Landsat satellite images from 2003 and 2023. The ground area, agriculture, and urbanization are linked to the LULC features. The various categories of classified land use and land cover features include the area of built-up regions, water bodies, cropland, forest, and barren land taken to predict the broad changes. Remotely sensed Landsat 5 images of 2003 and 8 images of 2023 were utilized to identify changes to accomplish this goal. This work clarifies the comparison of LULC classes for the Indore region.

This experimental study aimed to assess the effectiveness of soft tissue manipulation and Instrument Assisted Soft Tissue Mobilization (IASTM) in alleviating calf muscle tightness in children diagnosed with spastic cerebral palsy (CP). Cerebral palsy, a condition affecting two to three out of every 1,000 live births, encompasses a range of challenges related to movement, posture, gait abnormalities, and balance issues. Specifically, spastic diplegic cerebral palsy, characterized by leg spasticity, often results in walking difficulties, with tiptoeing as a common symptom due to calf muscle tightness. The study involved 30 children aged 5-12 diagnosed with spastic cerebral palsy at ACS Medical College and Hospital. Participants meeting the inclusion criteria were divided into two groups: Group receiving soft tissue manipulation and Group B undergoing IASTM. Outcome measures included goniometry and the Modified Ashworth Scale. Random sampling was employed to select subjects, with exclusions for specific medical conditions. Written consent was obtained and demographic data were collected. Based on goniometry and the Modified Ashworth Scale, both interventions demonstrated highly significant differences in mean values within their respective groups. The findings underscore the potential efficacy of both soft tissue manipulation and IASTM in addressing calf muscle tightness in children with spastic cerebral palsy.

Published: April 2024

The Indian economy is heavily dependent on agriculture as most people have agriculture as their source of income. Therefore, Indian researchers must focus on the various challenges in this field. As there is huge diversity in the cultivation scenario in the different geographical locations of the country. However, sugarcane is one of the important crops grown in the country's major states. The major challenge other than climate change is the impact of plant diseases on the various crops. Various infections are caused by the different viruses and bacteria that lead to poor crop yield, leading to losses to farmers, which reflects losses to the country. The identification of the diseases is done by due inspection by experts in the fields; however, it is difficult for farmers to contact them, and their availability will be a challenge.  Therefore, it is wise enough for the tools to be developed to extract the features from the images of the plant leaves and effectively identify the diseases. In this paper, a solution to the problem of disease identification is proposed with the help of the CNN model, the parameters of which are tuned using the grey wolf optimization neural network. The model based on IGWO is compared with the three other optimization algorithms, GWO, GA and PSO, out of which the IGWO and GA had the competitive result in accuracy comparison. However, the precision was better for PSO and GWO algorithms.

The diagnosis of periprosthetic joint infection is a difficult task because there is no absolute test to confirm or rule out infection. We have developed a local protocol for diagnosing periprosthetic joint infection to use a combination of diagnostic studies with the highest level of sensitivity and specificity.The purpose of the study: To evaluate the effectiveness of a local protocol for diagnosing periprosthetic joint infection to determine surgical treatment tactics.Methods. We analyzed 283 audits that took place during 2020-2022 at the Federal Center for Traumatology, Orthopedics and Endoprosthetics (Smolensk, Russian Federation). Patients with a preliminary diagnosis of aseptic loosening of knee or hip joint endoprosthesis components and periprosthetic joint infection were monitored. All patients were examined in accordance with the local protocol for the diagnosis of periprosthetic joint infection, which includes clinical and radiological data, CRP and ESR, analysis of the cellular composition of synovial fluid, microbiological examination of biopsies, endoprosthesis components, planned and frozen sections. The final diagnosis was made taking into account clinical and laboratory data. The effectiveness was assessed by delayed treatment results. Results. Positive microbiological cultures were isolated in 165 patients (58%), 150 patients had increased cytosis of synovial fluid (53%), leukocyte esterase was increased in 147 cases, according to the results of an urgent histological examination, 159 conclusions of «infectious type membrane» (56%) were obtained, a combination of increased ESR and CRP was observed in 93 cases.Conclusions. Analysis of the local periprosthetic joint infection diagnostic protocol showed that each stage of diagnosis allows to identify additional cases of infection, therefore, all patients admitted for revision endoprosthetics should be examined throughout hospitalization. The inclusion of urgent histological diagnostics at the intraoperative stage makes it possible to change the tactics of surgical treatment in a timely manner. In general, the local protocol of step-by-step diagnosis of periprosthetic joint infection with the inclusion of urgent histological examination helps to increase the chances of a successful outcome of revision endoprosthesis surgery, regardless of the nature of loosening.

Osteoarthritis is a degenerative joint disease that leads to damage to cartilage tissue and changes in the structure of bones, ligaments and muscles that surround joints. Despite numerous studies of osteoarthritis in our country and abroad, the wide variability in the development of the disease does not give a clear picture of the true cause of osteoarthritis formation. In the available domestic literature, there is still almost no information about genetic factors in the development of osteoarthritis. In this literature review, we discuss some evidence suggesting a genetic association with the risk of knee and hip osteoarthritis and summarize recent advances in this field, with special emphasis on genetically associated studies.
