Measuring the characteristics of seawater constituent is in great demand for studies of marine ecosystems and biogeochemistry. However, existing techniques based on remote sensing or in situ samplings present various tradeoffs with regard to the diversity, synchronism, temporal-spatial resolution, and depth-resolved capacity of their data products. Here, we demonstrate a novel oceanic triple-field-of-view (FOV) high-spectral-resolution lidar (HSRL) with an iterative retrieval approach. This technique provides, for the first time, comprehensive, continuous, and vertical measurements of seawater absorption coefficient, scattering coefficient, and slope of particle size distribution, which are validated by simulations and field experiments. Furthermore, it depicts valuable application potentials in the accuracy improvement of seawater classification and the continuous estimation of depth-resolved particulate organic carbon export. The triple-FOV HSRL with high performance could greatly increase the knowledge of seawater constituents and promote the understanding of marine ecosystems and biogeochemistry.
Algorithm for identification of emergencies prerequisites based on “if-then” rules
Authors:   Southern Federal University, Kravchenko D.Yu. , Kravchenko Yu.A. , Kuliev E.V. , Rodzin S.I.
Published: July 2023

The article is devoted to solving the scientific problem of decision support for the prevention and elimination of emergencies consequences based on solving the problem of emergencies identification types. The relevance of this problem is due to the need to optimize the risk of adverse effects on human health and the environment in connection with emergencies. The increased complexity of the tasks solved within the framework of the designated scientific problem is associated with the presence of information uncertainty in the complex accounting of heterogeneous characteristics, which in some cases can’t be normalized and brought to a single measurement scale. The authors have developed a heuristic algorithm for identifying the risks of emergency situations based on the “if-then” rules. New models of fuzzy inference have been built, for the implementation of which an algorithm has been developed for identifying the prerequisites for the occurrence of emergencies based on the “if-then” rules when solving problems of mass evacuation in the event of floods, hurricanes and other natural disasters, which allow making decisions on evacuation, partial evacuation, refusal to evacuate and others. Combinations of low-level “if-then” rules built for specific precedents for the occurrence and development of emergencies create unique sets of decision support alternatives to eliminate the consequences of a particular emergency. Each such alternative is essentially a trajectory that reflects the sequence of actions with many clarifying variations built on the basis of the fuzzy methods use for structuring operational information. To create test examples of specific ESs, the basic architecture of the ontological model of rules has been built, which has the form of a three-sided tensor. The main elements of this ontological model are entity concepts and relationships between them, the presence of which at the upper level of decomposition will indicate the risk of an emergency, and at each lower level it will expand the taxonomy of emergency situations possible detailed description and the necessary actions to prevent them or elimination of consequences.
Expansion of fuzzy sets to account for doubts and uncertainty of experts based on a modified aggregation operator
Authors:   Federal State Autonomous Educational Institution of Higher Education Southern Federal University, Danilchenko V.I.
Published: July 2023

Quantification in collective behavior and decision-making in fuzzy conditions is crucial to ensure the health and safety of the population. The task of modeling and predicting behavior in fuzzy conditions, as is known, has increased complexity due to a large number of factors from which an NP-complete multi-criteria problem is formed. There is a difficulty in quantifying the impact of fuzzy factors using a mathematical model. In this regard, the paper proposes a stochastic model of human decision- making to account for doubts and uncertainty of experts based on a modified aggregation operator. The developed fuzzy model combines fuzzy logic into a conventional model of social behavior. Unlike existing models and applications, this approach uses fuzzy sets and membership functions to describe the evacuation process in an emergency situation. The purpose of this work is to expand fuzzy sets to account for doubts and uncertainty of experts based on a modified aggregation operator and analysis of existing solutions. The problem statement in this paper is as follows: to form a set of fuzzy sets to account for doubts and uncertainty of experts based on a modified aggregation operator. The scientific novelty lies in the formation of a set of factors that form fuzzy rules for making dynamic decisions. The practical value of the work lies in the creation of fuzzy sets to account for doubts and uncertainty of experts based on a modified aggregation operator [1-3]. To implement the proposed model, the process of social behavior during evacuation, independent variables are determined. These variables include measurements related to social factors, in other words, the behavior of individual subjects and individual small groups, which are fundamental at an early stage of evacuation.
Side-channel leak detection methods for cryptographic information security tools
Authors:   Southern Federal University, Maro E.A.
Published: July 2023

The analysis of the parameters of hardware implementations of cryptographic information security tools is one of the promising areas for searching for vulnerabilities in information security tools. Cryptographic transformations underlying the applied software or hardware-software tools of information protection are either mathematically or computationally robustness. To guarantee the computational robustness of a cryptographic algorithm, it is fundamentally important to assess the possibility of including additional information about the ongoing cryptographic transformations to the attack model. Sources of such information about the operation of a cryptographic tool can be: the time of performing various cryptographic operations, the power consumption of devices during the encryption of various data blocks, electromagnetic, vibroacoustic and other emitting that occurs during the operation of hardware information security devices, specially created computational errors (faults). The article observes the approaches used to detect leaks through side-channels based on the analysis of the power consumption of cryptographic information protection tools during performing data encryption. The use of a hardware device emulator to search for statistical dependencies between the device’s power consumption and the encrypted data set that occurs in hardware implementations of cryptographic systems is described.

Book Review: Why Managers Matter: The Perils of the Bossless Company
Authors: Möller Ulrich
Published: July 2023

Nicolai Foss and Peter Klein's new book _Why Managers Matter: The Perils of the Bossless Company_ revolves around what the authors call the “bossless narrative,“ the unsubstantiated claim that organization without hierarchy and management is superior and will soon be dominant in companies around the world. This claim is predominantly made in popular, practitioner focused literature and business school classes. Unfortunately, these treatments often select bad examples of hierarchy and management and use them to argue that hierarchy and management are bad in general. The authors’ aim is to counter such arguments with a well-substantiated analysis and to provide a levelheaded entry to the overall discussion. They fully succeeded. Although critical of the bossless company, their reasoning is grounded in solid research and starts from the fundamental problems every organization faces.

Authors:   Rhode Island School of Design, Chen Debbie
Published: July 2023

“Drawdown: Play to Enter” is a cooperative game designed tosimulate the joys of negotiation and collective action required to work through climate strategy and resource management in the built environment. Disciplinary approaches to representingclimate activism often focus on a fixed condition of intervention (before vs. after), whereas game design embodies the active qualities of negotiation, compromise, balance, and incremental progress that occur in the in-between. By introducing the concept of interplay1 to architectural frameworks on the climate,game design expands the territory of architectural agency to model complex mechanisms of environmental stewardship that engage in scientific processes and stakeholder ecologies.The project leverages the fundamental principles of games as a medium of agency.2 Using the large table game board as a representational tool for our shared domain, players in DRAWDOWN are tasked with the shared responsibility of mitigating carbon outputs through the introduction of drawdown technologies while maintaining critical public programs.

Objectives: This study examined the effectiveness of carbendazim, Trichoderma harzianum, T. asperellum, T. viride, and a combination of the carbendazim and the bio-fungicides for the management of Foc both under in vitro and greenhouse conditions. Methodology and Results: The poisoned food technique was used in the in vitro tests. Fungal radial growth was recorded daily for seven days. In the greenhouse, the test products and Foc were applied directly into the soil, disease severity data was recorded at seven day intervals for 98 days using a scale of 1-5. Data on plant biomass was recorded at the end of the experiment (98 days). ANOVA was used to analyze data on fungal radial growth, disease severity, and plant biomass. The Student-Newman-Keuls (SNK) test was used to compare the results at P≤0.05. For the in vitro test, all treatments significantly (P<0.05) suppressed the growth of Foc compared to the untreated control. In the greenhouse trials a significant difference (P<0.05) in external/yellowing symptoms was observed but vascular discoloration was not different. Conclusions and application of findings: This study provides insights into the performance of bio fungicides and carbendazim in managing Panama disease. Keywords: Banana, Fusarium oxysporum f.sp. cubense, , Panama disease, Trichoderma sp.
Complete mode conversion between longitudinal and transverse waves by an elastic metamaterial slab with a double-scatterer structure
Authors: Liu Di , Peng Pai , Yu Wenjie , Du Qiujiao , Liu Fengming
Published: July 2023

In this work, we propose a design of a double-scatterer structure to achieve complete conversion for elastic bulk waves. Every unit of the elastic metamaterial slab contains a pair of scatterers with a relatively oblique direction. When the slab attaches on a semi-infinite solid background, it can completely convert the normal incident longitudinal wave into the reflected shear wave, or vice versa. The conversion can be attributed to the in-phase coupling of the double scatterers’ quadrupolar resonances. The coupled two quadrupoles could interact with the background and bring oblique displacements. Consequently, the oblique displacements generate horizontal displacements for reflected waves.

The Internet of Things (IoT) has revolutionized our lives by providing convenience in various aspects of our lives. However, for the IoT environment to function optimally, it is crucial to regularly collect data from IoT devices. This is because timely data collection enables more accurate evaluations and insights. Additionally, energy conservation is another crucial aspect to consider when collecting data, as it can have a significant impact on the sustainability of the IoT ecosystem. To achieve this, Unmanned Aerial Vehicles (UAVs) and Unmanned Ground Vehicles (UGVs) are increasingly being used to collect data. In this study, we delve into the problem of how UAVs and UGVs can effectively and efficiently collect data from IoT devices in an environment with obstacles. To address this challenge, we propose a Q-learning-based Obstacle Avoidance Data Harvesting (QOA-DH) method, which utilizes the principles of reinforcement learning to make decisions on data collection. Additionally, we conduct a comparison of the performance of UAVs and UGVs, considering the different restrictions and assumptions that are unique to each type of vehicle. This research aims to improve the overall efficiency and effectiveness of data collection in IoT environments and pave the way for sustainable IoT solutions.

Introduction. The search for affordable and accurate predictors of the outcome of COVID-19 is extremely important, as it provides the possibility to effectively correct the patient treatment tactics.
Aim of the study. To develop simple and accurate criteria based on the dynamics of red blood counts that predict the outcome of COVID-19.
Materials and methods. Observations were carried out in 125 patients with severe and extremely severe COVID-19, in whom indicators characterizing the state of red blood were determined in dynamics on days 1, 5, 7, 10, 14 and 21 after the hospitalization. ROC analysis was performed to calculate the threshold predictive values for survival and mortality.
Results. The total number of erythrocytes and the level of hemoglobin in severe and extremely severe patients did not go beyond the acceptable limits, although showed a tendency to decrease in the group of fatal cases. On the 1st and 21st days, the number of MacroR in the deceased patients was reduced compared to those in group of survivors. It has been established that the RDW-CV test can predict the outcome of the COVID-19 with a high degree of probability at a relatively early stage of disease. RDW-SD test can be an additional predictive criterion of COVID-19 outcome.
Conclusion. The RDW-CV test can be used as an effective predictor of disease outcome in patients with severe COVID-19.
Exosomes in the life cycle of viruses and the pathogenesis of viral infections
Authors: Kushch Alla A. , Ivanov Alexandr V.
Published: July 2023

Exosomes are extracellular vesicles of endosomal origin, with a bilayer membrane, 30160 nm in diameter. Exosomes are released from cells of different origins and are detected in various body fluids. They contain nucleic acids, proteins, lipids, metabolites and can transfer the contents to recipient cells. Exosome biogenesis involves cellular proteins of the Rab GTPase family and the ESCRT system, which regulate budding, vesicle transport, molecule sorting, membrane fusion, formation of multivesicular bodies and exosome secretion. Exosomes are released from cells infected with viruses and may contain viral DNA and RNA, as well as mRNA, microRNA, other types of RNA, proteins and virions. Exosomes are capable of transferring viral components into uninfected cells of various organs and tissues. This review analyzes the impact of exosomes on the life cycle of widespread viruses that cause serious human diseases: human immunodeficiency virus (HIV-1), hepatitis B virus, hepatitis C virus, SARS-CoV-2. Viruses are able to enter cells by endocytosis, use molecular and cellular pathways involving Rab and ESCRT proteins to release exosomes and spread viral infections. It has been shown that exosomes can have multidirectional effects on the pathogenesis of viral infections, suppressing or enhancing the course of diseases. Exosomes can potentially be used in noninvasive diagnostics as biomarkers of the stage of infection, and exosomes loaded with biomolecules and drugs - as therapeutic agents. Genetically modified exosomes are promising candidates for new antiviral vaccines.

The aim of the work is to assess the prevalence of hepatitis B virus drug resistance mutations and immune escape mutations in pregnant women in the Republic of Guinea.
Materials and methods. Blood plasma samples obtained from 480 pregnant women from different regions of the Republic of Guinea with laboratory-confirmed viral hepatitis B were studied. Nucleotide sequences for genotype identification and mutation detection were obtained using nested-PCR followed by Sanger sequencing, based on overlapping pairs of primers spanning the complete genome of the virus.
Results and discussion. In the examined group, the viral genotype E was the most prevalent (92.92%) compared with subgenotypes A1 (1.67%), A3 (1.46%), D1 (0.63%), D2 (1.04%) and D3 (2.29%). Among the examined HBV-infected pregnant women, 188 (39.17%) had undetectable HBsAg. Drug resistance mutations were detected in 33 individuals, which amounted to 6.88%. The following mutations were found: S78T (27.27%), L80I (24.24%), S202I (15.15%), M204I/V (42.42%). The presence of polymorphic variants not described as drug resistant has also been shown in positions associated with the development of drug resistance to tenofovir, lamivudine, telbivudine and entecavir (L80F, S202I, M204R). When analyzing the MHR and the region of a determinant, mutations were detected in 318 (66.25%) of pregnant women. In 172 of them, which amounted to 54.09%, multiple mutations were found. The amino acid substitutions in 13 positions associated with HBsAg-negative hepatitis B and/or potentially affecting HBsAg antigenicity were identified.
Conclusion. The high prevalence of immune escape and drug resistance mutations potentially associated with false-negative result of HBsAg screening, prophylaxis failure, and virological failure of therapy that has been identified among treatment naive pregnant women imposes a serious problem.
