Abstract. Clustering of gaseous sulfuric acid (SA) enhanced by dimethylamine (DMA) is a major mechanism for new particle formation (NPF) in polluted atmospheres. However, uncertainty remains regarding the SA-DMA nucleation parameterization that reasonably represents cluster dynamics and is applicable across various atmospheric conditions. This uncertainty hinders accurate three-dimensional (3-D) modeling of NPF and subsequent assessment of its environmental and climatic impacts. Here we extensively compare different cluster dynamics-based parameterizations for SA-DMA nucleation and identify the most reliable one through a combination of box-model simulations, 3-D modeling, and in-situ observations. Results show that the parameterization derived from Atmospheric Cluster Dynamic Code (ACDC) simulations, incorporating the latest theoretical insights (DLPNO-CCSD(T)/aug-cc-pVTZ//ωB97X-D/6-311++G(3df,3pd) level of theory) and adequate representation of cluster dynamics, exhibits dependable performance in 3-D NPF simulation for both winter and summer conditions in Beijing and shows promise for application in diverse atmospheric conditions. Another ACDC-derived parameterization, replacing the level of theory with RI-CC2/aug-cc-pV(T+d)Z//M06-2X/6–311++G(3df,3pd), also performs well in NPF modeling at relatively low temperatures around 280 K but exhibits limitations at higher temperatures due to inappropriate representation of SA-DMA cluster thermodynamics. Additionally, a previously reported parameterization incorporating simplifications is applicable for simulating NPF in polluted atmospheres but tends to overestimate particle formation rates under conditions of elevated temperature (> ~300 K) and low condensation sink (< ~3×10-3 s-1). Our findings highlight the applicability of the new ACDC-derived parameterization, which couples the latest SA-DMA nucleation theory and holistic cluster dynamics, in 3-D NPF modeling. The ACDC-derived parameterization framework provides valuable reference for developing parameterizations for other nucleation systems.
iPyCLES v1.0: A New Isotope-Enabled Large-Eddy Simulator for Mixed-Phase Clouds

Published: April 2024

Abstract. Recent field campaigns and advances in observational techniques have yielded a wealth of observations of stable water isotopes in the atmosphere, but the heirarchy of isotope-enabled models is not well-placed to leverage these observation for improving constraints on parameterized physics in global models. Here, we introduce the isotope-enabled Python Cloud Large-Eddy Simulation model (iPyCLES) for mixed-phase clouds. Isotopic tracers are implemented in a parallel passive water cycle and experience all processes and phase changes that affect the model's prognostic total water variable. Isotopic fractionation occurs during cloud and precipitation processes as well as surface evaporation, with facilities for applying external forcing. In addition to isotopic tracers, we extend the two-moment warm cloud microphysics scheme to enable prognostic simulation of cloud liquid water and ice while eliminating dependence on saturation adjustment. Relative to a one-moment mixed-phase scheme with saturation adjustment, the new microphysical scheme yields substantial benefits in simulating phase partitioning and isotopic exchange in mixed-phase regions. The LES model is based on an energetically-consistent implementation of the anelastic equations and employs high-order weighted, essentially non-oscillatory numerics, and is therefore theoretically suitable for simulations spanning the gray zone of the convective spectrum. In this initial evaluation, we present the results of test cases for non-precipitating subtropical shallow cumulus, precipitating subtropical shallow cumulus, and precipitating Arctic mixed-phase stratocumulus clouds. The iPyCLES simulations agree well with available observations and previous model simulations in all three cases, with distinct signatures among the cases that highlight the added potential of isotopic tracers. The benefits of the revised microphysics scheme are especially evident in the Arctic mixed-phase cloud test case, with vapor-liquid-ice exchange within the cloud producing a conspicuous peak in deuterium excess near the top of the cloud. As an idealized testbed, the iPyCLES model can bridge gaps between cloud chamber experiments, real-world observations, and global and regional models, allowing information provided by water isotopes to be translated more effectively into observational constraints for cloud and boundary layer parameterizations.

Abstract. This work assesses a recently produced 21-member climate model large ensemble (LE) based on the U.S. Department of Energy's Energy Exascale Earth System Model (E3SM) version 2 (E3SM2). The ensemble spans the historical era (1850 to 2014) and 21st century (2015 to 2100), using the SSP370 pathway, allowing for an evaluation of the model's forced response. A companion 500-year preindustrial control simulation is used to initialize the ensemble and estimate drift. Characteristics of the LE are documented and compared against other recently produced ensembles using the E3SM version 1 (E3SM1) and Community Earth System Model (CESM) versions 1 and 2. Simulation drift is found to be smaller, and model agreement with observations is higher in versions 2 of E3SM and CESM versus their version 1 counterparts. Shortcomings in E3SM2 include a lack of warming from the mid to late 20th century, likely due to excessive cooling influence of anthropogenic sulfate aerosols, an issue also evident in E3SM1. Associated impacts on the water cycle and energy budgets are also identified. Considerable model dependence in the response to both aerosols and greenhouse gases is documented and E3SM2's sensitivity to variable prescribed biomass burning emissions is demonstrated. Various E3SM2 and CESM2 model benchmarks are found to be on par with the highest-performing recent generation of climate models, establishing the E3SM2 LE as an important resource for estimating climate variability and responses, though with various caveats as discussed herein. As an illustration of the usefulness of LEs in estimating the potential influence of internal variability, the observed CERES-era trend in net top-of-atmosphere flux is compared to simulated trends and found to be much larger than the forced response in all LEs, with only a few members exhibiting trends as large as observed, thus motivating further study.

Abstract. The use of remote sensing methods to accurately measure cloud properties and their spatiotemporal changes has been widely welcomed in many fields of atmospheric research. The Nanjing Joint Institute for Atmospheric Sciences (NJIAS) Himawari-8/9 Cloud Feature Dataset (HCFD) provides a comprehensive description of cloud features over the East Asia and west North Pacific regions for the 7-year period from April 2016 to December 2022. Multiple cloud variables, such as cloud mask, phase/type, top height, optical thickness, and particle effective radius, as well as snow, dust, and haze masks, were generated from the visible and infrared measurements of the Advanced Himawari Imager (AHI) on board the Japanese geostationary satellites Himawari-8 and Himawari-9 using a series of recently developed cloud retrieval algorithms. Verifications with the Cloud–Aerosol Lidar with Orthogonal Polarization (CALIOP) 1 km cloud layer product and the Moderate Resolution Imaging Spectroradiometer (MODIS) Level-2 cloud product (MYD06) demonstrate that the NJIAS HCFD gives higher skill scores than the Japanese Himawari-8/9 operational cloud product for all cloud variables except for cloud particle effective radius. The NJIAS HCFD even outperforms the MYD06 in nighttime cloud detection; cloud-top height, pressure, and temperature estimation; and infrared-only cloud-top phase determination. All evaluations are performed at the nominal 2 km scale, not including the effects of sub-pixel cloudiness or very thin cirrus. Two examples are presented to demonstrate applications of the NJIAS HCFD for climate and typhoon research. The NJIAS HCFD has been published in the Science Data Bank (https://doi.org/10.57760/sciencedb.09950, Zhuge 2023a; https://doi.org/10.57760/sciencedb.09953, Zhuge 2023b; https://doi.org/10.57760/sciencedb.09954, Zhuge 2023c; https://doi.org/10.57760/sciencedb.10158, Zhuge 2023d; https://doi.org/10.57760/sciencedb.09945, Zhuge 2023e).

Published: April 2024

Abstract. The micro-electromechanical system (MEMS)-based seismic network of Trentino (NE Italy) consists of 73 low-cost accelerometers installed close to inhabited areas. These sensors have a suitable sensitivity to detect moderate-to-strong earthquakes but are able to record even weaker seismicity. The densely distributed peak ground acceleration values recorded by MEMS and other types of stations are integrated within the existing seismic monitoring procedure in order to automatically obtain a complete set of strong motion parameters a few minutes after the origin time. The exposure of the resident population and critical buildings is estimated by quantifying the different levels of shaking, which is expressed according to the Mercalli–Cancani–Sieberg intensity scale. These types of results, summarized in synthetic portable document format (PDF), can be useful for civil protection purposes to evaluate the state of emergency after a strong earthquake in a timely manner and to choose how and where to activate first aid measures and targeted structural monitoring.

Abstract. The AutoICE challenge, organized by multiple national and international agencies, seeks to advance the development of near-real-time sea ice products with improved spatial resolution, broader spatial and temporal coverage, and enhanced consistency. In this paper, we present a detailed description of our solutions and experimental results for the challenge. We have implemented an automated sea ice mapping pipeline based on a multi-task U-Net architecture, capable of predicting sea ice concentration (SIC), stage of development (SOD), and floe size (FLOE). The AI4Arctic dataset, which includes synthetic aperture radar (SAR) imagery, ancillary data, and ice-chart-derived label maps, is utilized for model training and evaluation. Among the submissions from over 30 teams worldwide, our team achieved the highest combined score of 86.3 %, as well as the highest scores on SIC (92.0 %) and SOD (88.6 %). Notably, the result analysis and ablation studies demonstrate that instead of model architecture design, a collection of strategies/techniques we employed led to substantial enhancement in accuracy, efficiency, and robustness within the realm of deep-learning-based sea ice mapping. Those techniques include input SAR variable downscaling, input feature selection, spatial–temporal encoding, and the choice of loss functions. By highlighting the various techniques employed and their impacts, we aim to underscore the scientific advancements achieved in our methodology.

Authors: Deepika Shende  , Gagandeep Kaur Sidhu
Published: April 2024

Enzyme-assisted aqueous extraction (EAAE) method is among the emerging technologies and eco-friendly process for oil extraction. The aim of this study was to evaluate the effect of oil extraction methods and packaging material on shelf life of maize germ oil. Maize germ oil extraction was done by EAAE and solvent extraction method. HDPE and glass bottles were used as packaging materials. Quality characteristics evaluated were acid number, pH value, total phenolics content, colour change, unsaponifiable matter, saponification value, peroxide value and density at 15-day intervals for 90 days of storage period. The quality characteristics of oil changed with the passage of storage periods, and maximum change upto 190 % increase in peroxide value occurred when oil was solvent extracted and stored in HDPE bottle. The quality parameters of EAAE extracted oil were superior to solvent extracted oil. During storage acid number, pH, total phenolics, unsaponifiable matter and peroxide value of oil were significantly affected (P< 0.05) by packaging material, storage period and method of oil extraction.

Published: April 2024

Soy protein isolate (SPI) were obtained through ultrafiltration using 10 kDa hollow fibre cartridge, 117.21 kPa trans-membrane pressure and 3.5 volume concentration ratio. SPI prepared by ultrafiltration possessed highest protein content (88±0.3 %) and 91.09±0.84 % nitrogen solubility index (NSI) as compared to 84±0.5 % protein content and 19.29±0.74 % NSI for acid precipitated and 85±0.5 % protein contentfor commercially availableSPI. Ultra filtered SPI also possessed highest value of emulsion stability (ES) of 51.96±1.42 %, whereas commercially available SPI exhibited the least value of 48.38±0.015 per cent. Highest value of oil absorption capacity (OAC) was 2.15±0.04 g.g-1 of protein for ultra-filtered, followed by 1.94±0.01 g.g-1 of protein for commercially available, and 1.73±0.04g.g-1 of protein for acid precipitated SPI. The hydrophilic lipophilic index (HLI) values for both ultra-filtrated and commercial SPIs were more than 2, indicating hydrophilic-lipophilic balance of proteins. However, water absorption capacity (WAC) and emulsion capacity were less for ultra-filtered sample as compared to commercially available counterpart. Commercially available SPI had highest value of 6.84±0.08 ml.g-1 of protein, whereas it was least at 1.67±0.016 ml.g-1 of protein for acid precipitated SPI.

Authors: Kallem Sushanth  , Anil Bhardwaj
Published: April 2024

Knowledge of geomorphologic characteristics is necessary for management of land and water resources in a watershed. These characteristics for Patiala-Ki-Rao watershed, located in Shivalik foot-hills of Punjab, were assessed using remote sensing and Geographic Information System (GIS). The form factor (0.27), circulatory ratio (0.53) and elongation ratio (0.59) indicated an elongated shape of the watershed, which might result in low-peaked hydrograph. Drainage characteristics of the watershed, namely drainage density (1.58 km.km-2), drainage texture (6.4 number.km-1), mean bifurcation ratio (2.4) and stream frequency (4.36 number.km-2) indicated quick disposal and low retention of runoff. Slope was less than 10 % in 21.04 km2 (41 % of watershed area), and 63.57 % and 16.39 % areas of the watershed were categorized as forest and agricultural lands, respectively. Furthermore, suitable runoff potential zones were identified by integrating thematic layers of slope, soil texture and land-use using GIS and multicriteria decision making techniques. The high, moderate and low runoff potential zones covered 13.74 km2 (26.73 %), 21.87 km2 (42.55 %), and 15.79 km2 (30.72 %) areas, respectively. The moderate to high runoff potential zones were mostly situated towards the upstream portion, whereas runoff potential was less in the downstream portion. Therefore, water harvesting and conservation treatment planning in the watershed is necessary for sustainable livelihood of the inhabitants.

Published: April 2024

A study was conducted to assess yield variability of paddy crop using automatic yield monitoring (AYM) system fitted on an indigenous grain combine harvester. Algorithms were developed to assess the on-farm yield variability and classify the field in different yield zones. Yield maps were created using ArcGIS and open source GeoDa software for four years (2014, 2015, 2016 and 2017). The calibration factor (CF) of AYM system for paddy crop was 6.79. Yield variations were recorded in one ha plot, and classified in five different yield zones of<1900 kg.ha-1, 2000-2999 kg.ha-1, 3000-3999 kg.ha-1, 4000-4999 kg.ha-1, and >5000 kg.ha-1. Variation in actual yield and yield measured by automatic yield monitor varied from (+) 2.8 to (+)5.1 per cent. Maximum temporal variability (14.7 %) was observed between the year 2014 and 2017. The AYM system could show the real-time temporal and spatial variability classification and quantification in paddy field.

Published: April 2024

Plum tomatoes were dried under hot air convection for producing powder. Different physical treatments were performed to achieve faster drying and milling. Initial moisture of tomato was 93.97 % with TSS of 4.6 %, which was dried to around 5 % moisture. Among the treatments, longitudinally cut in 16 pieces and cross-section slice segments took less time to dry and gave higher (6.4 %) drying yield. The effectiveness of treatments on drying characteristics and quality of tomato powder were examined. Mathematical models were employed by non-linear regression analysis to appropriately describe the drying behaviours. The physico-chemical quality characteristics of fresh and powder tomato were evaluated in terms of size and shape, peel pulp seed ratio, TSS, ascorbic acid, acidity, lycopene and solubility. The overall sensory perception revealed that all treatment samples of tomato powder reconstituted well in the form of soup-mix and achieved nearly equal scores on different quality attributes.

Sensor-based automated irrigation scheduling reduces the water losses, and applies precise quantities of water as per the crop water requirements, thereby improving the water use efficiency of irrigation systems. An automatic irrigation system (AIS) comprising of controller (raspberry pi), dual probe conductance-based soil moisture sensors and liquid crystal display it should read as liquid crystal display (LCD) LCD screen was developed to automate sprinkler irrigation system. The controller of the system was programmed using python programming language to control the solenoid valve and the motor on the basis of field-sensed soil moisture data. Field capacity and 50 % depletion of available soil moisture content were set as the upper and lower limits of soil moisture for switching the motor to ‘OFF’ or ‘ON’ condition, respectively. The developed system was compared with manual sprinkler irrigation for cabbage as indicator crop. Over the crop growing season, the moisture content under AIS was in the range of 0-10 % of soil moisture, indicating better accuracy of the AIS in sensing the water content in the crop root zone. The total cost of the AIS for 1 ha area was ₹ 16,058/-. The benefit-cost ratio of AIS was higher (2.59) as against manual irrigation (2.16), for cabbage.

Published: April 2024

In this work, the optical and morphological properties of an artificial opal-ZnO nanocomposite obtained by chemical deposition were investigated. ZnO nanofilm filled in the pores of artificial opals with photonic crystal properties showed a strong effect on their photonic band gap. After filling ZnO nanofilm in the pores of the opal, its photonic bandgap was found to redshift from a wavelength of 585 nm to 625 nm. The pore-filling factor of opal is calculated to be 9.1%. Under the influence of N2 laser radiation, luminescence with a maximum around 435 nm is excited in the opal-ZnO nanocomposite. Its spectrum is shifted towards shorter wavelengths compared to the luminescence spectrum of bare opal. It was discovered that the exciton luminescence of ZnO was suppressed, and the luminescence of the opal-based nanocomposite matrix was enhanced, possibly due to the transfer of energy from the ZnO nanofilm to the luminescence centers localized on the surface of the silicon dioxide from that the artificial opal is consisted.

Published: April 2024

Currently, there are known pig breeds that are characterized by a high rate of growth and development, precocity, fertility, individual structural features, high productivity and economic profitability. The study and breeding of new pig breeds helps to thoroughly analyze the data obtained in comparative, species, age aspects with similar types of farm animals. This fact helps to make a reliable assessment of all economic factors, as well as to analyze the quality of products received from the pig industry. The study was conducted at the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine. Cadaveric material for the study was delivered to the Department of Animal Anatomy of the St. Petersburg State University of Veterinary Medicine from the pig breeding complex of the Leningrad Region. To achieve this task, traditional morphological research methods were used, namely: fine anatomical dissection with injection of latex vessels, photographing, vasorentgenography with injection of lead meerkat, morphometry in the "RadiAnt" program. The largest main vessels diverting blood from the pig's stomach are the splenic, left and right gastric veins. Ultimately, they are syntopically connected to the small omentum, passing between the leaves of which they open into the portal vein of the liver. The branch of the right gastric vein branches along the loose type, and the splenic and left gastric veins branch along the main one. When conducting a comparative analysis of the morphometric characteristics of the diameter, the splenic vein will prevail over the left and right gastric veins. The results of the study can be used by veterinary specialists, in particular surgeons, to establish operative access to the stomach of pigs.

Methodological features of the implementation of pharmacoeconomic models in veterinary medicine
Authors: Ponamarev V. S.
Published: April 2024

The relevance of introducing pharmacoeconomic studies into veterinary medicine is undeniable, since they allow us to assess the cost and effectiveness of various medications and manipulations associated with their use, which helps veterinary specialists choose the most optimal treatment methods and prevent inappropriate or unnecessarily expensive con-sumption of medical resources. Such an economic assessment makes it possible to reduce the costs of veterinary care and ensure the availability of high-quality medical care for all categories of animals.

The main problem of using existing pharmacoeconomic methods in veterinary medicine is the actual absence or impossibility of relevant assessment of certain characteristics (for example, indicators of the “benefit” of treatment for compaion animals; the integral indicator QALY - “years of quality life saved,” etc.), which allows us to consider analysis and generalization of methodological features of the implementation of pharmacoeconomic models in veterinary medicine is an urgent task.

To achieve this goal, the scientific literature was analyzed (including bibliographic peer-reviewed databases such as Scopus, WoS, Pubmed, elibrary) with a further selection of relevant and current sources (published over the last 10 years) with their subsequent stratification according to the principle of applicability of the described methodological approaches for veterinary medicine, which were generalized and systematized.

As a result of the analysis, it was determined that in veterinary medicine it is permissible to use analytical, statistical and simulation mathematical models.

Pharmacoeconomic studies play an important role in assessing the relationship between treatment costs and outcomes. This allows you to evaluate the effectiveness of using a particular drug, conduct a comparative analysis of various treatment methods and make informed decisions about choosing the most suitable drug. In this way, pharmacoeconomic studies help improve the quality of veterinary treatment and ensure maximum benefit to the owner.

Chicken egg is a valuable dietary product and is often included in the daily human diet. In recent years, the demand of the population of our country for chicken eggs has increased and the requirements for the quality of table eggs of different categories have increased. In the trade network of St. Petersburg sells chicken table eggs of commodity categories of different manufacturers, among which quite often there is an egg, which by some indicators does not meet the requirements of regulatory documents. In this connection, a comparative analysis of commodity properties of hen's eggs of large poultry farms of the Leningrad region, selling their products in different retail chains of St. Petersburg was carried out. For the study was selected 10 packages of table chicken eggs 10 pieces per package of the following categories: selected, 1 and 2. Comparative analysis of eggs was carried out by their weight (one and ten pieces), presence of contamination, defects of egg shell and its integrity (fight), calculated shape index.

According to the conducted research it was established that the greatest deviations from the requirements of GOST on the weight of eggs and the presence of defects were established in the batch of eggs of the enterprise №1, sold in the retail network "Lenta". The analysis of the weight of eggs of all categories of poultry enterprise No. 2 corresponds to the permissible limit of GOST. In spite of single cases of non-compliance of egg weight to the trade categories indicated on the pack-age, the weight of 10 pcs. corresponded to the GOST requirements. 

According to the data of the conducted research it is established that the greatest deviations from the requirements of GOST on egg weight and the presence of defects were established in the batch of eggs of enterprise No.1, sold in the retail network "Lenta". The analysis of the weight of eggs of all categories of poultry enterprise No. 2 corresponds to the permissible limit of GOST. In spite of single cases of non-compliance of egg weight to the trade categories indicated on the pack-age, the weight of 10 pcs. corresponded to the GOST requirements. 

The table eggs produced by enterprise No.1 are sold in the trade network "Lenta" and "Magnit" with signs of contami-nation (31-36%) and breakage (3-9%), as well as with shell defects. (3-9%). For poultry farm No.2 the noted defects made up 17-22%, 1-6% and 1-4% respectively. Enterprise No.1 sells table eggs of different shapes with insignificant deviations from the recommended norm with egg shape index of 72-80%. At enterprise No.2 this index was 77-80%. That fully meets the normative requirements. It was found that eggs of category C2 of both producers to a greater extent met the requirements of normative documents and can be recommended to consumers of St. Petersburg.

Published: April 2024

Ophthalmopathy associated with parneoplastic syndrome is a poorly studied pathology of the dogs eye. They occur as a result of the malignant neoplasm’s systematic exposure on the animal's body. They appear in the form of non-specific clinical signs. Main objective of the study – to study the pathomorphological changes in the dog’s eyes with malignant neo-plasms. The material for the study were 30 eyeballs enucleated in dogs in the terminal stage of cancer. Autopsy material obtained from animals was subjected to standard histological processing. As a result of histological studies, pathomorphological changes in eyeball structures associated with Patnaik G2 and G3 mastocytomas (28.6% of cases), liver and kidney carcinomas (28.6%), lymphoma (28.6%) and spleen hemangiosarcoma (14.2%) were revealed in 46.7% of cases. The main histopathological changes were thickening of the iris due to inflammatory cellular infiltration (57.1%) and vasodilation of blood vessels (42.9%), the presence of fibrinous hemorrhagic exudate in the anterior chamber of the eye (28.6%), edema and inflammatory infiltration of the vascular membrane proper (42.9%), thinning, loss of layering and weak retinal atrophy (42.9%). The revealed histological changes indicate the predominant involvement in the pathological process of the vascular membrane of the eye with a violation of the hematophthalmic barrier, as the main pathogenetic mechanism for the development of endogenous uveitis against the background of malignant neoplasm in the animal body.

Authors: K. Kavitha, B. Sujatha Kavitha Guda,
Published: April 2024

Due to the growing requirement for powerful processing capabilities, safeguarding and processing sensitive data in big data systems has become an increasingly prevalent issue. Additional effort is required to secure sensitive data on a system with numerous connections, each of which has its own privacy policy, and to exchange cryptographic keys in accordance with the appropriate protocols for each of these parties. Data encrypted using homomorphic encryption algorithms can undergo the same kinds of arithmetic operations as data encrypted using plaintext. This allows for the outsourcing of computations to cloud services while also providing data privacy by processing in the encrypted domain. Also, key exchange sessions become easier for everyone involved because of this. This study presents new privacy-preserving clustering algorithms and homomorphic encryption systems that may together operate on a shared HPC infrastructure, like the cloud. Therefore, it is not necessary for the participants in this system to have a lot of processing power, as the system would distribute the most power-intensive jobs to any provider of cloud computing. Multiple clustering techniques can have their distance matrices computed in a way that does not compromise user privacy using our technology.

Authors: Satvir Singh Sushil Lekhi,
Published: April 2024

The inclusion of innovative technology into sensor networks has resulted in notable advancements in several industries, including mining, healthcare, military surveillance, and more. Using a multi-hop approach, nodes are placed strategically across the Region of Interest (RoI) in order to transfer data to the Base Station (BS). In order to address issues with energy consumption, effective cluster head selection, packet loss, routing algorithms, and energy efficiency, the Wireless Sensor Network (WSN) has become a key field of study. The objectives of this research are to increase nodes' Residual Energy, and lengthen the network lifetime. Using an effective clustering mechanism and Cluster Head  election procedure is the suggested method. The goal of choosing a CH is to minimize the distance from the base station while optimizing the node's remaining energy. The protocol acts in two stages: firstly, computing a new Threshold value for the cluster head election process, and secondly, applying a data fusion mechanism based  energy model is used in the network to reduce redundant energy transfer.

Authors: Raveendra K.
Published: April 2024

The research concerns the design and optimization of microstrip antenna arrays with sequential rotation-based MIMO configurations for 5G sub-3.5 GHz networks. In total, the use of five optimization approaches was accessed, namely, Bayesian optimization, sparse learning, genetic algorithms, particle swarm optimization, and convolutional neural networks, to evaluate their efficiency in improving antenna properties. In general, Bayesian optimization outperformed the other methodologies most consistently, with the value of the average antenna gain ranging from 0.84 to 0.88, SNR between 14.8 and 15.3, and radiation efficiency ranging between 0.90 and 0.93. The use of sparse learning also ensured a high level of performance, with the average gain ranging between 0.80 and 0.85, and the values of SNR between 15.2 and 15.7. Thus, this approach showed the highest resistance to noise. Genetic algorithms, particle swarm optimization , and CNN are also quite close to each other in the efficiency of properties, with the average antenna gain value ranging between 0.85 and 0.89 and the value of SNR between 14.7 and 15.1. In overall, the results of the research show that there is a variety of available approaches to the optimization of antenna design, and each of them has a number of advantages that can be of use for the improvement of the properties and makes it possible to derive a solution that outweighs others in terms of several properties and the efficiency of its application.
