Authors: S.Revathy
Published: September 2024

The aim of this article is to find the fuzzy shortest possible distance for a fuzzy   traveling salesman problem of hexagonal fuzzy numbers. We used to formulate the numerical example using dijkstra's algorithm.
Introduction The traveling salesman problem (TSM) involves finding the shortest possible route to multiple destination and returning to the starting point. —_ there we several applications of TSP, such as vehicle routing, scheduling. The TSP in a serious challenge for the logistics and supply chain industry because of involves optimizing the delivery router for multiple destinations while considering various constraints such as, traffic, delivery windows and customer request with multiple vehicle, more cities and multiple sales professionals, TSP become a more challenging to solve. In this article we proposed shorter possible distance route from multiple destination and returning to the starting point using ranking method of hexagonal fuzzy numbers.
Conclusions: The ranking approach is used in this paper to transform hexagonal fuzzy numbers into expected time, or standard time, for each activity. Thus, using the DIJKSTRA algorithm, the fuzzy shortest path is found. It assists decision makers in selecting the optimal, shortest path in a fuzzy environment by applying the ranking algorithm.
Fluid Mechanics and the Evolution of Biological Complexity
Authors: Goldstein Ray
Published: September 2024

A fundamental issue in biology is the nature of evolutionary transitions from unicellular to multicellular organisms: What are the advantages of being physically larger and more complex? Green algae are models for this transition, as they span from unicellular species to multicellular ones with tens of thousands of cells, all of which swim through the action of flagella that are closely related to the cilia found throughout the human body. A paradigm for understanding this transition is the phenomenon of phototaxis, directed motion toward light. In this talk I will describe experimental and theoretical work on the physical mechanism of algal phototaxis, spanning 3 orders of magnitude in cell number, that reveals an evolutionarily conserved response which raises interesting questions in fluid mechanics, dynamical systems, and cellular decision-making.

Published: September 2024

Records of cirriped species in the family Scalpellidae from the Nordic Seas are scarce. New records of the four species Amigdoscalpellum hispidum (G. O. Sars, 1890), Ornatoscalpellum stroemi (M. Sars, 1859) Tarasovium cornutum (G.O. Sars, 1879) and Weltnerium nymphocola (Hoek, 1883) from the eastern part of the Norwegian Sea are reported. The record of W. nymphocola is the first from the Norwegian coastline, found on the shelf slope, and the rarely found T. cornutum was found in a depth representing the lower depth range for this species. Based on new data from the Norwegian Sea and from the literature the species’ connection to specific oceanographical regimes is discussed.

Published: September 2024

Human cytomegalovirus (CMV ) infection is the most prevalent infection affecting organ transplant recipients, and it is a cause of morbidity and mortality in patients undergoing kidney transplantation. "e introduction of ganciclovir (GCV ) for both prophylaxis and treatment has vastly improved patient outcomes. GCV resistance can be caused by mutations in the UL97 phosphotransferase gene or the UL54 polymerase gene. It occurs in 1 to 2% of kidney transplant recipients with CMV infection or disease. Antiviral resistance should be considered when increased viral loads and disease progression are observed despite the administration of adequate antiviral therapy. "e degree of resistance varies depending on the type of mutation present. We report a patient with resistance to GCV due to a UL97 del597-599 mutation who, despite typically requiring an 8-fold increase in GCV dose, showed a signi#cant decrease in viral load with just a double dose increase. However, the patient’s overall clinical course remained complicated. Due to severe leukopenia, maribavir had to be started, with a good response. Nevertheless, he ultimately died due to indirect CMV-related complications. "is case also highlights the complexity of transplant patients, who present multiple challenges ranging from infections to therapy management.

Abstract: This paper explores a data-driven method to investigate the stabilization of intermittent controlled discrete-time systems (ICDTSs) with unknown parameter matrices. First, the pre-collected inputstate data is used to supersede the accurate prior system model. Then, in order to obtain the data-dependent stabilization conditions of ICDTSs, a novel relationship is designed among the control width, rest width, and convergence rate. Unlike existing studies on the stabilization of ICDTSs, this paper only needs the collected input-state data. Thus, the time-consuming process of model identification is avoided. In addition, to ensure an acceptable performance level, the data-based guaranteed cost control is also considered, and a new cost function for ICDTSs is correspondingly built. Finally, two simulations are presented to demonstrate the effectiveness of the theoretical analysis.

Abstract: As an optimization technique, the gradient descent method is widely adopted in the training process of deep learning. In traditional gradient descent methods, the gradient of each dimension has the same weight wtih the updating direction, which results in poor performances when there are multiple small gradient dimensions (e.g. near the saddle point). To improve the accuracy and convergence speed of the neural network training, we propose a novel multi-dimensional adaptive learning rate gradient descent optimization algorithm (M-AdaGrad) in this paper. Specifically, in the M-AdaGrad, the learning rate will be updated according to a newly designed weight function related to the current gradient. Experiments on a set of sigmoid-based functions verify that, compared with traditional gradient descent methods such as AdaGrad and Adam, the M-AdaGrad gives more confidence to the larger gradient direction and has a larger probability to reach a more optimal position with a faster speed. Due to its excellent performance in network training, the M-AdaGrad is successfully applied to the magneto-optical nondestructive test of crack detection based on the generative adversarial network.

Abstract: Adaptive control is an effective approach for mitigating undesirable deviations in prescribed closed-loop plant behavior. However, conventional adaptive control methods often exhibit slow responses in various control tasks. This paper introduces a novel adaptive control method to achieve fixed-time synchronization in a class of coupled neural networks. We present coupled neural networks with multiple switching topologies and design a fixed-time adaptive control strategy for this system. Furthermore, we establish a criterion to ensure the fixed-time stability of the closed-loop system. Two numerical examples are provided to demonstrate the effectiveness and accuracy of the theoretical results.
Geochemistry and petrogenesis of the mafic dyke swarm of the north eastern part of the Mesoproterozoic Irumide Fold Belt, North eastern Zambia

Published: September 2024

The area of north eastern Zambia between, Chama and Lundazi towns, is underlain by biotite gneisses of the Mesoproterozic Irumide Fold Belt dominated by biotite gneisses of the Kampemba group, of the Irumide Fold Belt. A complex of a mafic dyke swarm that appears to occupy a NE trending fracture zone, occurs mainly between the two towns. The dykes have the same trend with the fracture zone. Individual dykes vary in size from about 100s of metres long by a few 10s of metres wide, to about 4 km long and about 100 metres wide. This study examined the petrogenesis of the mafic dyke swarm through the application of petrography, whole rock geochemistry as well as isotope geochemistry. Fifteen fresh dyke swarm samples were sent to Actlabs in Canada for whole rock geochemical analysis. Three of the fifteen samples were analysed for Rb-Sr and Sm-Nd isotope geochemistry, as well as age determinations by K-Ar age dating method. The results received on age determination (geochronology) gave the ages, 1522 ± 90 Ma, 1067 ± 55 Ma and 608 ± 35 Ma. Sm and Nd grades ranged from 1.99 – 3.112 ppm and 6.666 – 9.88 ppm respectively. eNd were calculated by the laboratory at -5.23, -8.23 and -9.73. 87Sr/86Sr returned values of 0.710886, 0.714503 and 0.719612. From the petrographic study of the thin sections and photomicrographs, the studied dyke rocks were classified as gabbroic. They were composed mainly of plagioclase, clinopyroxene, hornblende with subordinate olivine, quartz, sericite, epidote and opaque phase minerals. The dyke rocks occur mainly in course and medium grained varieties as only two of the twelve samples examined, were fine grained. The several diagrams which were generated from whole rock geochemical data and applied in the evaluation of petrogenetic processes revealed that the dyke swarm was emplaced in a back arc continental subduction environment. The geochemical data further revealed that fractional crystallisation affected the magma of both types of rocks identified in the study, tholeiitics and calc-alkalics. Since no two samples came from the same dyke, it was deduced that all the mafic dykes in the Study area experienced various levels of fractional crystallisation of possibly olivine, clinopyroxenes, plagioclase feldspars and hornblende. These were the main minerals which were identified in petrographic studies of the same samples. Both types of dykes show enrichment of the source magma by addition.

Methodology: Based on the analysis of the national and local legislation of CDW management frontier cities in Colombia, this study puts forward an alternative to the formulation of a comprehensive management plan. Based on this analysis, the conditions and characteristics of medium-sized cities such as Barranquilla are studied and analyzed in order to provide a comprehensive alternative for the management and treatment of this kind of waste. Result: The prevention, storage, collection, transportation, use, and final disposal aspects that should be considered in the CDW integrated management plan most suitable for Barranquilla City are determined. According to these special characteristics and conditions, a scheme of treatment plants is proposed. Conclusion: In view of the rapid development of Barranquilla in recent years, Barranquilla needs to quickly adjust its CDW management mode. The city recognizes that the separation of source and use is at the core of the model needed to achieve sustainable management processes. In addition, the shortcomings of the current management system are found, and combined with the application of the linear economic model, a management model based on the principle of circular economy is proposed.

Published: September 2024

A proper evaluation of the health risks and economic burden incurred by urban residents due to air pollution is crucial for regional air pollution management, the formulation and execution of environmental policies, and the promotion of public health in China. Utilizing data on PM2.5 concentration and population density from 338 Chinese cities between 2015 and 2017, this study employs the Exposure-Response model to estimate the premature mortality and disease incidence linked to PM2.5 exposure. It also assesses the direct economic losses associated with PM2.5 pollution using the Value of Statistical Life (VSL) and Cost of Illness (COI) approaches. The findings indicate that: 1) Between 2015 and 2017, there was a slight improvement in PM2.5 concentration levels, yet the overall spatial distribution of pollution remained largely unchanged. The most polluted areas were concentrated in the Beijing-Tianjin-Hebei region and adjacent cities; 2) PM2.5 pollution has resulted in substantial reductions in both health and economic losses. Specifically, the number of residents affected by severe health issues due to pollution decreased by 23.9%, and the total economic loss for residents decreased by 24.24%, from 1824.96 billion yuan in 2015 to 1382.64 billion yuan in 2017; 3) The rising urbanization rate has intensified the health impacts and economic costs of PM2.5 pollution, particularly in cities with both high pollution levels and high urbanization rates, such as Beijing and Tianjin. Moving forward, it is imperative to implement tailored measures to enhance PM2.5 monitoring and control in key cities, thereby effectively safeguarding the health of urban residents.

Objective: The study aims to investigate the impact of atmospheric nitrogen dioxide (NO2) levels on pediatric outpatient consultations for respiratory illnesses in the Yuexiu District of Guangzhou, China. Methods: Data on atmospheric NO2levels, weather conditions, and outpatient visits for respiratory diseases were gathered from a children's hospital in Guangzhou's Yuexiu District over the period of 2014 to 2016. Spearman rank correlation analysis and time-series analysis employing a generalized additive model were utilized to examine the association and lagged effects between NO2concentrations and concurrent pediatric respiratory outpatient visits. Results: The annual mean NO2concentrations in Yuexiu District during 2014, 2015, and 2016 were 6130, 6046, and 6081 μg/m3, respectively, and the number of days exceeding national standard values was 70, 64, and 62, respectively. The time-series analysis revealed a significant impact of NO2on respiratory outpatient visits from day 0 to day 7, with the most pronounced effect observed on lag day 0 (lag0). An excess risk (ER) of 145% (95% CI: 93%–198%) was observed on lag day 0 (lag0). The highest cumulative lag effect and ER of 307% (95% CI: 204%–410%) were found on lag days 0 to 6(lag06 d). Conclusion: The rise in NO2levels in Guangzhou's Yuexiu District between 2014 and 2016 was associated with an increase in pediatric respiratory disease outpatient visits.

Published: September 2024

The health of individuals is intimately linked to air quality, making it crucial to investigate the pollutants that influence it. A sequential Logistic multi-classification approach, which utilizes the distance between classes, was applied to analyze the air quality data of Chengdu spanning from May 2019 to April 2020. By leveraging the inter-class distance metric, the multi-class classification challenge was converted into a series of binary classification tasks. Using a sequential strategy, binary Logistic regression was then employed for each task. The accuracy rate post-stepwise regression was utilized to assess the impact of various pollutants on air quality. The findings indicate that PM2.5, PM10, NO2, and O3 are the four primary pollutants with the most significant collective influence on Chengdu's air quality. Consequently, the government should enhance the joint monitoring of these pollutants and develop targeted policies to mitigate their levels.

Published: September 2024

The high-temperature pyrolysis oxidation process was utilized to produce reed biochar, which was then employed as a carrier for immobilizing the predominant petroleum hydrocarbon-degrading bacteria. The study investigated the effects of this biochar-bound microbial immobilization on the remediation efficacy and enzymatic activity of soil contaminated with petroleum hydrocarbons. The findings indicated that after 40 days of treatment with reed biochar-immobilized microorganisms, the soil's petroleum hydrocarbon removal rate reached 55.01%, markedly surpassing the removal rates of biochar (45.82%) and the untreated control group (24.83%). Additionally, it was observed that the biochar-immobilized microorganisms significantly enhanced the activities of soil enzymes such as dehydrogenase, catalase, urease, and polyphenol oxidase. The application of biochar-bound microbial immobilization technology not only boosts the cleanup efficiency of petroleum hydrocarbon-contaminated soil but also substantially elevates the soil's biological enzyme activity.
The present state of lead (Pb) and zinc (Zn) contamination in agricultural soil as revealed by meta-analytic findings
Authors: Ning Yinzhong
Published: September 2024

Agricultural soil serves as the fundamental resource for grain production, with its quality being integral to both the national economy and the well-being of the population. As economic and societal development progresses, the levels of lead (Pb) and zinc (Zn) in farmland soil are on the rise. Currently, research into the total quantities and speciation distribution of Pb and Zn in agricultural soil, as well as their influencing factors, is fragmented, and there is a gap in comprehensive understanding regarding the transformation mechanisms and pollution status of various forms of these heavy metals. To gain a clearer picture of the heavy metal pollution in soil, as well as the distribution and transformation dynamics of different forms, this study conducts an integrated analysis of the pollution levels, speciation distribution, and influencing factors of Pb and Zn in Chinese farmland soil. Additionally, it assesses the ecological risk of heavy metals using principal component analysis and the geoaccumulation index. The findings indicate that the average concentrations of Pb and Zn are 4045 mg/kg and 10699 mg/kg, respectively. The residual form of Pb is most predominant in the Northwest, while the exchangeable form is most prevalent in the Southwest. The residual form of Zn constitutes over 50% of its presence. The analysis reveals that pH is the primary factor influencing the speciation distribution of heavy metals. The combined results of the geoaccumulation index and the potential ecological risk index (RI) suggest that Pb levels at the study site exceed those of Zn, though both are classified as posing a slight risk. A holistic analysis of soil environmental factors reveals that the speciation distribution of heavy metals reaches an equilibrium state through the interaction of multiple factors.

Published: September 2024

This study sought to find the relationship between the two variables and decide which domain of online learning strategies significantly influences the students’ speaking performance in English. This study employed a descriptive-correlational method. There were 100 senior high school students involved in this study. The research instruments used were an adapted survey questionnaire and a speech task. The results showed a high mean score for the online learning strategies of students, and the students’ speaking performance was described as good. The relationship between the two variables was insignificant, and only metacognitive strategies positively influenced the students’ speaking performance. The students must learn how to use online learning strategies appropriately to overcome challenges in the online learning environment since online learning strategies might not be typical for students when delivering speaking performance tasks. Thus, teachers may teach students how to employ online learning strategies to help them improve their online learning.
