judicialização do acidente de trabalho e a competência jurisdicional no Brasil
Authors: Cusciano Dalton Tria
Published: March 2023

O objetivo deste artigo foi o de identificar os motivos da judicialização do acidente de trabalho, discutindo os possíveis efeitos que a unificação de competências jurisdicionais teria sobre a judicialização do acidente de trabalho. A pergunta que norteou esta pesquisa foi: Qual o índice de ações acidentárias de aposentadoria por invalidez e auxílio-doença impetradas em face do Instituto Nacional de Seguridade Social julgadas pelas 16º e 17ª Câmaras de Direito Público do Tribunal de Justiça de São Paulo nos anos de 2017 e 2018 que tiveram em algum momento trâmite pela Justiça Federal e como como tal índice se relaciona com os princípios de maior celeridade e da devida prestação jurisdicional diante da não unificação das competências? A hipótese de que uma minoria processos julgados no período indicado pelas Câmaras teve trâmite pela Justiça Federal foi confirmada, diante da tramitação pela Justiça Federal de 8% dos processos julgados em segunda instância pelo TJSP, o que equivale a 242 processos. Tais processos por tramitarem em justiças distintas tiveram maior duração temporal quando comparado aos similares de tramitação exclusiva por competência estadual, reduzindo a efetividade da prestação jurisdicional, o que teria sido evitado com a unificação de competências.   Para tanto, foram analisados 3.123 acórdãos julgados pelo TJSP, por meio dos da análise de decisões, consistente na coleta dos acórdãos proferidos pelos julgadores das 16ª e 17ª Câmaras de Direito Público, que têm competência específica para julgar apenas as lides acidentárias nos anos de 2017 e 2018.
A challenging responsibility - care for older parents in Turkish immigrant families
Authors: Liversage Anika
Published: March 2023

Objective: This article explores care for older immigrants from Turkey, particularly with regard to receiving support from their family in a welfare state such as Denmark.
Background: The first labour migrants to Europe are currently entering old age in growing numbers. While research on the intersection between immigration and aging is expanding, knowledge about how older immigrants receive care is still limited, making this a timely study.
Method: The article draws on interviews with 30 individuals – older parents, children and grandchildren – from 22 families both with and without pressing care needs. Two of the families utilized a Danish care policy where a family member is remunerated by the municipality for carrying out specified care tasks.
Results: The data show that, in many families, both older and younger family members consider providing family care very important. The needs for such provisions are deepened due to the older immigrants’ often limited command of the Danish language, which makes them unable to communicate with Danish care workers. In some families, older members refuse to receive public help, increasing the need for support from their next of kin.
Conclusion: While the existence of large family networks can facilitate provisions of family care through sharing, family responsibilities can also be stressful in a dual-earner society such as Denmark. Primary caretakers are often female, and such women’s engagement in providing family care may lead already vulnerable individuals to become further marginalized in society.

Published: March 2023

Pests that often attack mustard plants are armyworm (Spodoptera litura F.), tritip caterpillar (Plutella xylostella L.), leaf caterpillar (Crocidolomia binotalis Z.), a common pest that also often attacks mustard plants is the cabbage caterpillar (Hellula undalis F. ), green steamed grasshopper (Atractomorpha crenulata), and snail (Helix pomatia). One of the efforts in controlling Plant Pest Organisms (OPT), this study aims to determine the effect of gadung tuber extract (Discorea hispida Dennst) in controlling the level of damage caused by mustard leaf pests. This vegetable pesticide comes from plants that contain toxins but the residue left does not interfere with the surrounding environment. The treatment of gadung tuber extract given in this study were water control, chemical control and four treatments of botanical pesticide concentration. This research lasted for 35 days from seeding to harvest. The results showed that each treatment had a different attack intensity level. The treatment of gadung tuber extract has the effect of being used as a botanical pesticide against mustard leaf pests because the K4 treatment (10 ml) with an attack intensity percentage of 7.97 showed the best results in controlling the level of damage to mustard leaf pests.
Spanish Society: Stable Instability
Authors: Khenkin S.
Published: March 2023

Instability has become a “new normal” for Spain. This relatively young democracy with numerous semiperipheral traits is seeing new challenges overlap the long-standing old ones, which makes instability greater than in more developed European Union countries. The article is the first Russian academic paper to cover the entirety of destabilizing factors in contemporary Spanish society. Among the destabilizers one can identify those that may be traced back to Spain’s historical past. These include polarization of opinions on the legacy of the Civil War and the Franco regime, elements of authoritarian attitudes in mass consciousness and political practices of organizations, as well as conflicts between supporters of monarchy and the republican movement, between avid catholics and secularists. Another contributing factor is fragility of the political system that shows itself in personalist (caudillist) parties, whose mechanisms for intra-party democracy are still immature. There is also a disproportionate electoral legislation, politicized judiciary, and the unfinished nation state that has failed to truly integrate Catalonia and the Basque Country. Another destabilizer is volatile social and economic development. Spain has one of the highest rates of unemployment and precarious employment in the EU, intensive growth of precariat, flawed healthcare and education systems, immigration galvanizing both indigenous nationalism and xenophobia, with the reluctance of many immigrants to adapt to Spanish culture and society. Minimizing risks related to destabilizing factors is an imperative for Spain’s present and future.

In this study, the effects of in-feed clinoptilolite treatment on biomarkers such as serum amyloid A (SAA), haptoglobin, apolipoprotein A–I (APO A–I), and paraoxonase-1 (PON1) activity, triglycerides (TRIG) and high-density lipoprotein cholesterol are investigated in dairy cows with subclinical mastitis. A total of 69 Holstein dairy cows, aged between 2 and 7 years, kept on a farm in North-Western Croatia, were included in the experiment. The cows were randomly assigned into the following three groups: (1) clinoptilolite (CPL) group with subclinical mastitis (n = 20), treated with in-feed 50 g natural powdered clinoptilolite twice daily from the 270th day of pregnancy to the end of the study; (2) non-treated cows (n = 19) with subclinical mastitis (SCM); and (3) the control group (CON) of healthy cows (n = 30). The blood samples were taken on the day of calving and on days 5, 12, 19, 26, 33, 40, and 60 after parturition. The concentration of SAA was highest in the SCM group (p < 0.001). PON1 activity was statistically significantly lower (p < 0.001) in the cows from the SCM group than in the CPL and CON groups. Decreased PON1 activity and increased APO A–I were observed in the SCM group. The positive effect of the addition of vibro-activated clinoptilolite in the feed of treated cows resulted in reduced values of APO A–I, SAA, and haptoglobin, and higher activity of PON1 during the two-month period of lactation after calving, on the basis of which we can assume that they may be less sensitive to infection with SCM.
The Cambrian Explosion: macroevolution and biomineralization
Authors: McMenamin Mark A. S.
Published: March 2023

Recent advances in our understanding of the Cambrian evolutionary diversification event (Cambrian Explosion) show that, although eumetazoan stem taxa were present in the late Proterozoic, a tremendous burst of macroevolutionary change occurred near the beginning of the Cambrian. Explanations relying on paleoecological feedback are insufficient to explain the macroevolutionary patterns observed, particularly those associated with the near simultaneous appearance of new higher taxa. The diversity of biomineralization types among the small shelly fossils of the early Cambrian can be explained if putative ancestral scleritome-bearers (found in both Proterozoic and Cambrian strata) had, as some new data suggest, intact scleritomes that hosted individual sclerites of varying biomineral composition.

We investigated which species of waterbirds at Bolivar, a wastewater treatment plant in Metropolitan Adelaide, South Australia, are likely to have been immigrants from the ephemeral wetlands in the arid zone. To do this, we compared the abundance of waterbird species observed at Bolivar during the dry period in the eastern arid zone of late 2018 and 2019 with that during the subsequent wet period 2020–2022. Pink-eared Duck Malacorhynchus membranaceus, Grey Teal Anas gracilis, Australasian Shoveler Spatula rhynchotis, Hardhead Aythya australis and Blue-billed Duck Oxyura australis were all more abundant during the arid-zone dry period. By contrast, Australian Shelduck Tadorna tadornoides, Eurasian Coot Fulica atra and Black Swan Cygnus atratus showed increased abundance in spring and early summer in all years, with no marked differences between the dry and wet periods in the arid zone. Wader species that breed in the Northern Hemisphere – Sharp-tailed Sandpiper Calidris acuminata and Red-necked Stint C. ruficollis – also tended to be more abundant during the arid-zone dry year, as did Red-necked Avocet Recurvirostra novaehollandiae, whereas Pied Stilt Himantopus leucocephalus tended to be more abundant in the arid-zone wet years, with breeding by this species taking place in spring. These data suggest that Bolivar is a critically important conservation site for waterbirds and that various species use this location as a refuge during dry times in the arid zone of eastern Australia.
A Novel Process for Recovery and Exploitation of Polyesters and Polyamides from Waste Polymeric Artifacts
Authors: Barbieri Massimo , Terreni Edoardo , Tollini Flavio , Storti Giuseppe , Moscatelli Davide
Published: March 2023

Plastic waste constitutes one of the most important sources of pollution worldwide. Despite the growing recycling trend, nowadays there are no effective technologies that can compensate for the continuous increase in plastic production. Polyesters and polyamides are one of the most produced single-use plastics, mainly used in manufacturing textiles and soft drinks bottles. Today, only a very low fraction of these polymers can be recycled. It can be done by exploiting two leading technologies: mechanical and chemical recycling. Mechanical recycling represents, nowadays, the most used industrial application. However, it can treat a very narrow range of waste materials due to the impossibility of removing dyes and the deterioration of mechanical properties due to the incompatibility of different plastic materials. Another critical limit of this recycling technology is the limited number of recycling loops that can be done due to the thermal degradation that occurs during the extrusion process. The second possibility is chemical recycling, which allows the depolymerization of the original product to recover the monomers directly. The main drawbacks are the long reaction times and the many solvents needed to achieve high-purity products. Therefore, chemical recycling is economically feasible, only for big companies that can produce the virgin polymer in situ. In this work, a new technology has been patented. This process is constituted of three main steps. The first one is the distillation-assisted cyclodepolymerization (DA-CDP), introduced as a modification of the CDP process. In this unit, cyclic oligomers together with high molecular weight compounds have been produced. Then, after polymer purification, it is possible to achieve the same molecular weight of the initial polymer in less than 30 minutes, exploiting the ring-opening polymerization (ROP) in the next step.

Authors: Costantiello Alberto , Leogrande Angelo
Published: March 2023

In this article, we analyse the determinants of Regulatory Quality-RQ for 193 countries in the period 2011-2020. We use a database from ESG-Environment Social Governance of the World Bank. We apply OLS, Panel Data with Fixed Effects and Panel Data with Random Effects. We found that the variables that have the most positive impact on RQ, among others, are “GHG Net Emission”, “Mean Drought Index”, and “Heat Index”. We also found that the variables that have the most negative impact on RQ are among others “Renewable Energy Consumption”, “Voice and Accountability” and “Rule of Law”. Furthermore, we have applied the k-Means algorithm optimized with the Elbow Method and we find the presence of five clusters. In adjunct, we confront eight machine learning algorithms to predict the value of RQ and we found that the best predictor is Polynomial Regression. The predictive level of RQ for the analysed countries is expected to diminish of -1,29%. In the end, we present a network analysis with the Euclidean distance and we found the presence of a structure of seven networks using augmented data.
Leaf Gas Exchange and Photosystem II Fluorescence Responses to CO2 Cycling
Authors: Bunce James
Published: March 2023

Experimental systems to simulate future elevated CO2 conditions in the field often have large, rapid fluctuations in CO2. To examine possible impacts of such fluctuations on photosynthesis, intact leaves of field grown plants of five species were exposed to two-minute cycles of CO2 between 400 and 800 mol mol-1 lasting a total of 10 minutes, with photosynthesis, stomatal conductance and PSII fluorescence measured at the end of each half-cycle, and also 10 minutes after the end of the cycling. Prior to the cyclic CO2 treatments, steady-state responses of leaf gas exchange and fluorescence to CO2 were determined. In four of the five species, in which stomatal conductance decreased with increasing CO2, the cyclic CO2 treatments reduced stomatal conductance. In those species, both photosynthesis and the photochemical efficiency of PSII were reduced at limiting internal CO2 levels, but not at saturating CO2. In the fifth species, there was no change in stomatal conductance with CO2, and no change in either photosynthesis or PSII efficiency at any CO2 level with CO2 cycling. It is concluded that in many, but not all, species fluctuations in CO2 may reduce photosynthesis at low CO2 partly by decreasing the photochemical efficiency of photosystem II, as well as by decreasing stomatal conductance.

The winged bean is an underutilized legume that has the potential to contribute to nutrition and food security globally, especially in sub-Saharan Africa (SSA). However, very little research attention is paid to exploiting its full potential due to a lack of adequate knowledge of the existing genetic diversity in the available winged bean germplasm. To bridge this gap, seed morphometric and selected agro-morphological traits which are crucial for yield and seed quality determination in crop plants were used to assess the genetic diversity of thirty accessions of winged bean sourced from the Gene bank of the International Institute of Tropical Agriculture (IITA), Ibadan. The thirty winged accessions were evaluated under field trials at three agro-ecological zones in Nigeria. The agro-morphological data as well as the seed morphometric dataset obtained from a Multi-Spectral Imaging (MSI) system were subjected to Analysis of Variance (ANOVA), Principal Component (PC) analysis, cluster analysis, and correlation analysis. Significant differences (p < 0.05) were observed among the accessions for all measured traits. The first three PCs accounted for 93% of the variation observed among the accessions for all measured traits. Accessions were grouped into three clusters based on the agro- morphological traits and three clusters under the MSI system. Seed yield per plant had the highest estimates of significant positive correlation with hundred seed weight, pod weight per plant, etc. at both phenotypic and genotypic levels. TPt-31 had the highest seed yield per plant, pod weight per plant, and early maturity while TPt-7 had an extended flowering and maturity period, the highest number of pods per peduncle and pods per plant as well as the lowest seed yield. These accessions could serve as a good resource for future winged bean improvement programs. The result also confirmed that the MSI system is an invaluable tool for discriminating among accessions of the same crop species.

The performance of modern wireless communication systems is highly dependent on the adoption of multiple antennas and the associated signal processing. In 5G and 6G networks, beamforming and beam management become challenging tasks due to aspects such as user mobility, increased number of antennas, and the adoption of higher frequencies. Artificial intelligence, and more specifically, machine learning, are efficient tools to reduce the complexity involved in generating beams and the overhead associated with beam management without sacrificing system performance. Therefore, AI-aided beamforming and beam management have received a lot of attention recently. This article presents a complete survey on this topic, emphasizing open problems and promising directions. The discussion includes architectural and signal processing aspects of modern beamforming and beam management. The article presents communication problems and respective solutions using centralized/decentralized, supervised/unsupervised, semi-supervised, active, federated, and reinforcement learning.

Published: March 2023

Green microalgae including those from the genus Lobosphaera are exploited in biotechnology to obtain valuable fatty acids e.g., arachidonic acid (C20:4, ARA) for the production of infant formulae, food and feed additives. In nature, microalgae frequently exist in naturally immobilized state (as biofilms) with limited cell division rate and increased stress resilience. In biotechnology, immobilization of microalgae on artificial cell carriers simplifies biomass harvesting, increases culture robustness and productivity. The choice of suitable cell carrier is central to biotechnology of immobilized culture. Cell carriers based on the natural amine-containing polymer chitosan and synthetic polyethylenimine (PEI) are promising candidates for immobilization of phototrophic microorganisms. This is the first report on the effects of immobilization on PEI and chitosan on the accumulation and composition of polyunsaturated fatty acids, including ARA, in Lobosphaera sp. IPPAS C-2047. The immobilization on PEI increased ARA percentage in the total tatty acids and ARA accumulation by 72% and 81%, compared with the suspended cells cultured respectively in complete or nitrogen-deprived medium 14 days. Immobilization of Lobosphaera sp. on the chitosan-based carrier declined ARA but increased oleic and α-linoleic acid percentages. Mechanisms of the effects of immobilization on fatty acid profiles of the microalgae are discussed.

Published: March 2023

In a previous companion study, satellite data were used to describe peculiar characteristics of ocean surface wave fields, generated by two extra-tropical cyclones (ETCs) rapidly propagating in the North Atlantic. Based on a 2D parametric wave model, further details are now provided to analyse and interpret the spatio-temporal evolution of ETC very intense generated waves. Significant wave height and wavelength values are shown to reach extreme values, 18 m and 500 m, respectively. Resulting energetic swell systems waves then radiate in the whole eastern part of North Atlantic, and more particularly in the Norwegian sea region. Moving to higher latitudes, wind forcing characteristics of ETCs evolve, with the shape of the wind field changing from quasi-cyclonic to "air jets/Icelandic lows". In this paper, the resulting swell generation and propagation, after the deformation of an individual ETC, are studied, as well. Confirmed with comparisons with multi-satellite observations, the application of the parametric-2D wave-ray model is demonstrated to provide robust and highly detailed information on wave generation under very complex wind regime changes.

The intense emergence of mucilage in the Marmara Sea in 2021 has raised concerns due to its potential impact on the global marine system. Considering the potential of mucilage threatening the diverse ecosystems, it is important to define the mucilage microbiome. However, studies dedicated to exploring the biodiversity of mucilage are limited and de novo approaches are needed to understand unexplored biodiversity of mucilage microenvironment. This study aimed to investigate mucilage and water samples from certain stations in Marmara Sea. For this reason, 11 mucilage, 2 pre-mucilage water and 3 clean sea water were collected from 16 stations. DNA isolation, shotgun metagenome sequencing and bioinformatics analysis were performed. It was revealed that the mucilage microbiome and the clean water microbiome were different from each other, and the reads that could not be assigned to any taxon (dark matter) accounted for 58% (p=0.014) of the mucilage metagenome. The clean water had a higher presence of Euryarchaeota (p=0.014), Proteobacteria (p=0.019) and Rhodothermaeota (p=0.034), while Chlamydiae (p=0.014) and Fusobacteria (p=0.034) were found in excess in the mucilage. The study produced the first comparative data on clean sea water and the mucilage microbiome using shotgun metagenomics approaches.
Tutorial on Bayesian Optimization
Authors: Nguyen Loc
Published: March 2023

Machine learning forks into three main branches such as supervised learning, unsupervised learning, and reinforcement learning where reinforcement learning is much potential to artificial intelligence (AI) applications because it solves real problems by progressive process in which possible solutions are improved and finetuned continuously. The progressive approach, which reflects ability of adaptation, is appropriate to the real world where most events occur and change continuously and unexpectedly. Moreover, data is getting too huge for supervised learning and unsupervised learning to draw valuable knowledge from such huge data at one time. Bayesian optimization (BO) models an optimization problem as a probabilistic form called surrogate model and then directly maximizes an acquisition function created from such surrogate model in order to maximize implicitly and indirectly the target function for finding out solution of the optimization problem. A popular surrogate model is Gaussian process regression model. The process of maximizing acquisition function is based on updating posterior probability of surrogate model repeatedly, which is improved after every iteration. Taking advantages of acquisition function or utility function is also common in decision theory but the semantic meaning behind BO is that BO solves problems by progressive and adaptive approach via updating surrogate model from a small piece of data at each time, according to ideology of reinforcement learning. Undoubtedly, BO is a reinforcement learning algorithm with many potential applications and thus it is surveyed in this research with attention to its mathematical ideas. Moreover, the solution of optimization problem is important to not only applied mathematics but also AI.

Published: March 2023

La generación de efluentes industriales está convirtiéndose en uno de los problemas ambientales más relevantes, debido a su capacidad para contaminar a los cuerpos de agua naturales. El agua residual procedente de los procesos industriales contiene cargas tóxicas de diferentes contaminantes que pueden variar en concentración, entre los cuales se encuentra a los metales pesados. Las trazas de metales pesados requieren atravesar un proceso de remoción antes que el agua residual llegue a su disposición final. Existen diversos métodos capaces de remover estos contaminantes en aguas residuales entre los que se incluyen: métodos convencionales, basados en procesos físico- químicos y; métodos no convencionales, caracterizados por ser innovadores y usar sistemas biológicos. La presente revisión evalúa la aplicabilidad de diversas técnicas de tratamiento para la eliminación de metales pesados en aguas residuales provenientes de industrias; asimismo, señala las ventajas y limitaciones de cada una de las técnicas con el fin de reconocer su efectividad.

Published: March 2023

Evaluación de la tasa de filtración de Semimytilus algosus (Mytiloida: Mytilidae) expuestos a diferentes concentraciones de microplásticos y temperaturas. Introducción: El uso desmedido de plástico, conjuntamente con el fraccionamiento de estos polímeros (MPs: microplásticos), y el incremento de temperatura en los océanos, generan perturbaciones en la vida marina, los cuales se pueden relacionar con alteraciones en el metabolismo de organismos filtradores, como los mitílidos. Objetivo: Evaluar el efecto de diferentes concentraciones de MPs y temperaturas sobre la tasa de filtración (TF) de Semimytilus algosus. Métodos: Los organismos (n = 72) fueron expuestos a tres concentraciones de MPs (< 125µm): 0.000 mg.L-1 (MPs0), 0.125 mg.L-1 (MPs1) y 0.250 mg.L-1(MPs2) en combinación con la microalga Isochrysis galbana (1 x 106 cel.ml-1.día-1), y cuatro temperaturas (17, 20, 23 y 26 °C) por un periodo de 21 días. Resultados: A medida que aumentó la concentración de MPs, se redujo la TF de S. algosus. Respecto a la temperatura, al día 7 de evaluación, se observó una mayor TF a 23 °C para todos los tratamientos, y durante los días 14 y 21, la TF mostró los menores valores de TF a 23 °C y 26 °C. La acción conjunta de la presencia de MPs e incremento de temperatura, afectó negativamente la TF de S. algosus, donde ambos factores ocasionaron el descenso de la TF para todos los tiempos de evaluación. No se registró mortalidad a 17 °C para ningún tratamiento, y la mayor mortalidad (67%) fue para de MPs1 a 26 °C y MPs2 a 20 °C. Conclusiones: Este estudio demuestra el efecto adverso de la presencia de MPs e incremento de temperatura sobre la TF de S. algosus.
Variación de los parámetros pélvicos posicionales de bipedestación a decúbito prono en adultos asintomáticos peruanos
Authors:   , Córdova Del Castillo Víctor Harold
Published: March 2023

El propósito principal del presente trabajo es determinar si existe variación en los valores medidos de los parámetros pélvicos posicionales (1): inclinación pélvica (PT) y pendiente sacra (SS); cuando las personas asintomáticas pasan de bipedestación a decúbito prono. La locomoción en bipedestación erecta es propiedad del ser humano, algunos orangutanes, el canguro y el extinto tiranosaurio rex, aunque estos últimos tienen una cola que los estabiliza; es de subrayar que aunque las aves también presentan bipedestación, lo hacen con biomecánica muy diferente (2). En el bipedalismo es fundamental la morfología y posición de la pelvis interactuando con la organización de la columna vertebral y regulando el balance entre ambos. El estudio de la pelvis está determinado por sus parámetros: incidencia pélvica (PI), la cual es independiente de la postura corporal; y, en contraste, la inclinación pélvica (PT) y la pendiente sacra (SS), las cuales son dependientes de la postura y sus valores cambian con la rotación de la pelvis sobre las cabezas femorales (eje de las caderas) (3,4).

Authors: Saxena Ankit
Published: March 2023

The requirement of the wireless network is increasing with the developments in every field of society. As it helps to use contactless controls and communications with different applications. From the fifth generation and beyond, the need of wireless networks is to fulfil the capacity requirement and offered better connectivity between peer entities. To offer high throughput within the wireless network, beamforming is one among the optimum solutions that provides better connectivity and bandwidth among peer entities. In the work, we assessed the wireless capacity of beamforming wireless network using the Frequency Division Duplexing (TDD) and Time Division Duplexing (TDD) type for multiple Transmission Modes (TM) under different radio conditions. We modify the channel properties with respect to varying the Signal to Noise Ratio (SNR) and measured the performance of both systems independently in terms of throughput, and Block Error for both the duplexing using quantitative and ratio analysis. Further, we conclude that the beamforming for higher TMs offered high throughput in best to worst channel conditions.

Published: March 2023

Transportation, temperature control, and the production of pharmaceuticals all rely on 71 percent of the Earth's surface, which is covered by water. Valuable things, including minerals, metals, corals, and coral reefs, can be identified with the help of the IoUT, among other applications. One of the crucial uses is in preventing damage caused by natural disasters. The IoT boosted concepts for a new undersea network (IoUT). Underwater networks have many drawbacks, including a lack of dependability, limited bandwidth, long propagation delays, high processing demands, high energy costs, and node detection with secure communication. Real-time, secure data communication is a significant area of research for us, along with node identification and dynamic network configuration. IoUT faces severe obstacles in the form of these issues. Our strategy involves a dynamic graph for network design, an AFA algorithm based on AI for node recognition, and ECC for a secure communication mechanism. In order to increase discretion and provide the undersea network with adequate robust security.
