Validity and Reliability of the 23-Item Preterm Birth Risk Assessment Scale
Authors: Kim Jeung-Im
Published: January 2023

AbstractPurpose: This study aimed to perform a psychometric evaluation of the preliminary preterm birth risk assessment scale (PBRAS-K) of 32-item. Method(s): There were 299 subjects, 167 in the exploratory factor analysis (EFA) group and 132 in the confirmatory factor analysis (CFA) group, who delivered before 37+0 weeks after having preterm symptoms and were admitted to high-risk pregnancy maternal-fetal intensive care units (MFICU). After an item reduction process in EFA, the psychometric property scales were assessed using SPSS 26, and CFA was accomplished using AMOS 27. Results: The Kaiser-Meyer-Olkin measure (KMO) and Bartlett’s χ2 test of sphericity confirmed the adequacy of the sample for factor analysis (KMO = .81 (> .80), χ2 = 1841.38, p < .001). The final version of the PBRAS-K was comprised of 23 items within seven dimensions. Factor analysis identified items explaining 65.9% of the total variance. The PBRAS-K had a mean score of 35.58 (±10.35) and showed a high internal consistency and satisfactory reliability with a Cronbach’s alpha of .85. The PBRAS-K had a low correlation with risk scoring of preterm delivery (RPD) for discriminant validity (r = .45, p < .001), a positive, high correlation with the Somatic Awareness Scale with Spontaneous Preterm Labor (SPL-SAS) for criterion validity (r = .65, p < .001), and with pregnant stress for convergent validity (r = .57, p < .001). RPD and SPL-SAS were moderately correlated (r = .53, p < .001). Conclusion(s): The PBRAS-23-K is a valid and reliable instrument for assessing pregnant women’s risk of preterm birth. Clinical nurses are encouraged to apply and obtain information for effective interventions in MFICU. This scale has meaningful results and reflects the voices of women who had a preterm birth. The scale should be evaluated for standardization and cut-off scores using larger subject sizes in the future.
Microbial Evolution: The Dilemma of Direct and Indirect Viral Self-Camouflaging
Authors: Carp Theodor-Nicolae
Published: January 2023

Microbial immune escape represents the primary cause of induced pathogenesis in humans, and it represents a pivotal method used by viral agents to increase their load and suppress key mechanisms of the innate and adaptive immune system. This phenomenon represents the primary factor that led to the onset of the 1918-1920 A(H1N1) Influenza and 2020-2022 COVID-19 pandemics, and it possibly played a major role in the onset of the AIDS pandemic as well. Moreover, repeated incidents of immune evasion could be associated with higher rates of cellular aging (Jackson et al., 2017), most likely due to the consequent increased demands of energy consumption. Highly developed viral immune evasion ultimately indicates the high inner intelligence of human immunity due to reflective and imitative characteristics of reactions that are produced against initial actions. Ribonucleic acid-based viral genomes contain open reading frames, which consist of genes producing sixteen non-structural proteins. Such proteins play a considerable role in desensitizing first-line immunity during cellular infection, and non-structural proteins 1, 10 and 16 have the strongest effects against a healthy expression rate of Type I and Type III Interferon-encoding genes. Type I Interferons consist of IFN-alpha, -beta, -delta, -epsilon, -omega, -tau and -zeta, whilst Type III Interferons consist of IFN-lambda1, -lambda2 and -lambda3, and they act as stimulators of intracellular signalling cascades that in turn lead to the activation and expression of interferon-stimulated genes (Brown et al., 2022). The earlier the interferon-stimulated genes are activated, the lower the extent of pro-inflammatory mediation and overall, the more effective the antiviral immune response will be, given the exponential nature of the viral load increase. Non-structural protein 16 methylates the 5’ cap of the virus, making the pathogen-associated molecular patterns less recognisable by pattern-recognition receptors, and it requires activation by bonding with non-structural protein 10. It is preserved in the S-Adenosyl-L-Methionine pocket of the SARS-CoV-2 genome. Non-structural protein 1 (NS1) directly cleaves the host cell mRNA producing Type I and possibly Type III Interferons, thereby preventing a translation process of the immune proteins. NS1 has recently been found to often be packaged into exosomes once secreted by the viral genome in the cytosol, meaning that exocytosis and paracrine signalling to neighbouring cells before their actual infection is possible. As a result, NS1 is highly capable of silencing the first-line immune responses of uninfected neighbouring cells as well, thereby highlighting the need to adjust the focus of therapeutics and vaccinology toward first-line immunity and further indicating its foundational importance in the support for the development of precise and balanced defenses against microbial agents of concern (EL SAFADI et al., 2022).
Three-Dimensional Evaluation of Microscopic Wheel Surface Topography in Creep Feed Grinding Using Ceramics Grinding Wheel
Authors: Fujimoto Masakazu , Fujita Masashi
Published: January 2023

The surface topography of ceramic grinding wheels used in creep feed grinding is examined in this study. Creep feed grinding experiments are performed using seeded gel (SG) grinding wheels. The three-dimensional surface of the grinding wheel is observed using a two-dimensional high-definition laser displacement sensor, and the effective cutting-edge number is calculated based on three-dimensional surface observations. Microscopic wear behaviors of grain cutting edges are examined based on scanning electron microscope (SEM) images. The cutting-edge area percentage is calculated based on SEM images via the discriminant analysis method. Results show that the micro self-sharpening phenomenon can be evaluated quantitatively. Micro sharp cutting edges on grains and normal grinding forces are suppressed. Subsequently, the relationship between the grinding characteristics and behaviors of the SG wheel working surface is investigated.
Effects of Bit Shape of Electroplated Diamond Tool Used for Drilling Small Diameter Holes in Glass Plate on Machining Fluid Flow and Chip Discharge
Authors: Oyamada Tappei , Mizobuchi Akira , Ishida Tohru
Published: January 2023

Our laboratory has been exploring the development of tools for drilling holes in glass plates, and the drilling techniques to be adopted for it. A devised tool shape that could prevent the occurrence of cracks at the exit holes achieved high quality through hole drilling of 100 holes or more using only the drilling cycle. However, crack-free drilling beyond this number of holes cannot be performed. This is due to the adhesion of the residual chip on the tool surface when the number of holes increases. Therefore, further improvement of chip discharge is needed to achieve crack-free drilling. In this report, we consider that chip discharge results from the flow of the machining fluid. To investigate the cause of chip discharge, we analyzed the flow of the machining fluid in the hole using computational fluid dynamics and the supposed chip discharge conditions. The results obtained in this study are summarized as follows. (1) In the case of a cylindrical tool, the Z-axis directional flow of the machining fluid did not occur in the hole. This is because the tool does not have bumps to agitate the fluid on the side, and the gap between the tool and the inner surface of the hole is narrow. (2) The plate side widened the gap between the tool and inner surface of the hole. Therefore, the fluid was likely to flow in the Z-axis direction in the hole. (3) For the tool with the plane side bit, the flow entered the hole from one plane side and exited the hole from the other plane side. (4) When the tool end is spherical, the Z-axis directional flow of the fluid occurs at the tool end. (5) The fluid flow of the devised tool weakened as the drilling depth increased. To improve the chip discharge performance of the designed tool, the Z-axis directional flow of the machining fluid must occur in an area deeper than 2 mm.
Development of High-Speed Rotation Polishing System with Slurry Confinement and Friction-State Control
Authors: Yoshitomi Kenichiro , Shimada Yoshinori , Une Atsunobu
Published: January 2023

An increased removal rate is required to improve the production efficiency during the polishing of ultrahard-to-process materials. The rotational speed of the polishing pad is increased to increase the removal rate. However, research has not been extensively conducted on polishing with a high-speed rotation because slurry is rarely supplied to a polishing area by the centrifugal force generated through polishing pad rotation. In this study, we developed a high-speed rotational polishing system with slurry confinement and friction-state control. The casing and spiral groove of the polishing pad were designed to confine the slurry in a polishing area, and friction-state control was adopted to maintain the spindle torque generated by friction between the pad and wafer at the target spindle torque. Based on the experiments investigating the supply efficiency, the developed polishing method can supply sufficient slurry to the polishing area by the optimized spiral groove pattern and perform polishing without slurry shortage at a high-speed pad rotation of 10000 min-1. In addition, the results of polishing experiments for a sapphire wafer revealed that friction-state control and wafer rotation could stabilize the polishing state effectively. The proposed polishing system can achieve a higher removal rate than the conventional polishing system.

Published: January 2023

This study was conducted in the Wahat Elnukhila area, about 600 km northeast of El-fashier town, northern Darfur State, to produce broad–base data on the geographical distribution of soils, characterization of soils using some soil indicators (ECe, pH and SAR), explore the natural land cover and evaluate the soil suitability for agricultural activities in the study area. The study area covers (20000 feddans). This research was based on the data and information extracted from the soil survey, remote sensed landsat, Enhanced Thematic Mapper (ETM+) images dated 2018, in addition to field observation aided by GPS receivers and geographic information system were used to generate soil map in the study area. By using the American soil classification system (FAO, 1990 and 2006) study area may be classified into three units, the total area of the three units and natural vegetation cover decreased in the following order: unit1 (12734 feddans) > unit 2 (3994 feddans) > unit 3 (3272 feddans), green covers as a result of the availability of quantities of ground and surface water, which distinguishes it from the rest of the surrounding desert lands. The predominant vegetation cover is Imperata cylindrica (halfa), Tamarix (Tarfa), phragmites (communist)“ Alboes”, Citrullus Colocynthis (Hanzal), Ischaemum muticum and p. dactylifera (date palm). Regarding soil texture, drainage, soil depth, and fertility status for units 1, unit 2, and unit 3, can be described as follows: sandy to loamy sand, well-drained, shallow and low fertile, coarse texture to moderate, moderately drained, shallow to moderate and low fertile, gravelly surface, moderatly drained, shallow to moderate and very low fertile respectively. Soil analysis reveled that there was high inherent risk of soil salinity and sodicity, especially unit 1. In general, the result showed that there were clear aspects of wind erosion represented as large areas affected by the sand encroachment form of crescent dunes and rocks interspersed with hills and plateaus. Furthermore, soils of the targeted area were formed from the accumulation of creeping and portable aeolian sands. The research site lies in the southeastern part of the border triangle between Sudan, Egypt, Libya and Chad, which is severely affected by wind erosion because the site was bare, open with no wind barriers or shelter belts, also this area falls under the sand moving winds of the Sahara. These are the northerly winds that prevail in Northern Darfur State. Furthermore, the prevalent climatic conditions including high temperature, rainless area and relatively high wind speed are conducive to high wind erosion. The area in danger unless serious measures carried out to reduce wind erosion. The area has very low potential suitability for agriculture. The study area was rich in wild life such as deer, rabbits, birds, many insects and snakes.
AOA Critical Issues: Dichotomies in Leadership. Presidential Address to the AOA, June 17, 2022
Authors: Sebastianelli Wayne J.
Published: January 2023

This speech was given at the 2022 American Orthopaedic Association (AOA) meeting in Providence, Rhode Island, on June 17, 2022, and discusses the most important elements of leadership. A sense of extreme ownership is required for effective leadership. Ownership allows leaders to delegate responsibilities to others and to instill confidence and trust in the people closest to them. True leaders recognize that every situation creates value, regardless of the outcome, because each and every encounter is an opportunity to learn. Oftentimes, a situation creates a natural dichotomy or controversy. Good leaders must recognize this dichotomy and balance the decision-making that is required for such an occurrence for the ultimate good of the individual or organization. True leaders will include rather than exclude the people around them and will graduate the responsibilities of individuals as the skills and trust of those individuals develop. Those in charge must also recognize that leadership includes intelligence, compassion, and instinct. Leaders who are health-care providers must keep patient care as the true “North Star” so that appropriations of space, personnel, and finances are maximally utilized. Finally, true leaders achieve their goals through the core principles of balance, orchestration, growth, inclusion, and envision.

Currently, organic waste is still underutilized. If managed properly, it will produce a sale value and can also be used for various purposes. Organic waste that is still underutilized is like palm fronds. In areas especially Kalimantan, oil palm plantations are very common, the harvesting system in oil palm plantations produces fresh fruit bunches (FFB) and waste in the form of palm fronds which are piled up between the oil palm plants (gangan mati). The purpose of this research is to make a machine that can chop oil palm fronds into animal feed. Before making a coconut frond chopping machine, the design and force calculations are made first. The amount of torque obtained is 1,300 kg.f.mm, the motor power used in the initial design is 3 Hp, and the length of the belt used using pulley 1 with a diameter of 100 mm and pulley 2 with a diameter of 150 mm is A55 inch.

The Relevance of Ibn Khaldun’s Economic Thought on The Prices Mechanism in The Modern Economy
Authors: Nisak Khoirun
Published: January 2023

Ibn Khaldun is known as one of the Muslim scholars who made significant contributions to the social sciences, including economics. Ibn Khaldun developed his thoughts on the price mechanism in the market by looking at the condition of Andalusian society at that time. This study aims to discover Ibn Khaldun's thoughts regarding the price mechanism, both from the supply and demand sides, and whether these thoughts remain relevant to today's economic phenomena. The results of the analysis show that naturally,  the price in the market is formed due to the process of attraction between demand and supply. This research found that people's tastes are a factor that shifts the demand curve.   Meanwhile, product scarcity and production costs shift the supply curve. Ibn Khaldun's thought aligns with modern economic theory and remains relevant to present economic phenomena.
Mapeamento participativo com emojis: uma estratégia de ensino de áreas sujeitas a alagamento e inundações

Published: January 2023

Os mapas são fundamentais para entender o espaço geográfico, contudo comumente são apresentados prontos para os(as) alunos(as) não permitindo qualquer inserção de dados. À vista disso, o objetivo deste trabalho foi realizar um mapeamento participativo identificando pontos sujeitos a alagamento e inundações. Ao invés de somente localizar, os(as) alunos(as) usaram emojis para representar as emoções. O trabalho detém um caráter qualitativo e apresenta os resultados de uma oficina aplicada na turma de 8º ano de uma escola localizada em Santa Maria (RS). Em relação aos conceitos usados na oficina, os alunos(as) relataram que conheciam somente o de alagamento, pois este fenômeno faz parte de seu cotidiano, já que nenhum deles indicou que vive em pontos de inundação. O primeiro grupo mapeou 16 pontos, sendo que seis foram com o emoji de raiva,pois relataram que em dia de chuva molhavam os tênis indo para a escola, principalmente nas áreas próximas aos trilhos de trem. Ao passo que o segundo grupo mapeou 12 pontos, sendo que três se referiam à frente da escola, representando raiva, tristeza e fúria, pois estava chovendo e toda entrada estava alagada, fazendo com que molhassem seus calçados. Em síntese, a interação na oficina foi abaixo da esperada, pois provavelmente os alunos não estão acostumados com metodologias ativas. Destaca-se que outras emoções foram citadas nos emojis como a violência e poluição, confirmando possibilidades de aplicação da metodologia com outras temáticas urbanas.sendo que três se referiam à frente da escola, representando raiva, tristeza e fúria, pois estava chovendo e toda entrada estava alagada, fazendo com que molhassem seus calçados.

Neste texto, apresentamos aspectos relacionados à importância dos mapas táteis, como recursos didáticos mediadores para o conhecimento geográfico dos estudantes cegos. Um estudo de caso em desenvolvimento, cujo recorte espacial se dá no município de Francisco Beltrão-PR, com a participação de 15 professores da Educação Básica, que foram entrevistados a respeito do ensino dos estudantes cegos inclusos e sobre o trabalho com os conceitos geográficos, tanto no ensino regular como no Atendimento Educacional Especializado, das Salas de Recursos Multifuncionais - Área da Deficiência Visual (SRM-DV) e no Centro de Apoio Pedagógico para Atendimento às Pessoas com Deficiência Visual (CAP). A linha metodológica segue pela Teoria Histórico Crítica, como base na elaboração e adaptação de recursos didáticos táteis. O trabalho é realizado no Laboratório e Grupo de Pesquisa Representações, Espaços, Tempos e Linguagens em Experiências Educativas (RETLEE), da Universidade Estadual do Oeste do Paraná, Campus de Francisco Beltrão (UNIOESTE-FB), onde as matrizes de mapas táteis são construídas baseadas nos dados recolhidos na investigação e no indicativo da maior necessidade para estudar e ensinar sobre a relação do lugar no mundo dos cegos. As bases foram construídas e avaliadas por professores e estudantes cegos. Os mapas foram reproduzidos em acetato na máquina de termoformagem. Seguimos na afirmativa de que nenhuma proposta pedagógica por si só dá conta da realidade. Portanto, defendemos a perspectiva teórica de Vigotski, pois indica que a mediação dos conteúdos considera a realidade para proporcionar o conhecimento e que sejam analisados os aspectos históricos e sociais do contexto estudado.
Improved environmental stimulus and biological competition tactics interactive artificial ecological optimization algorithm for engineering optimization
Authors: guo wenyan , Wu Mingfei , Min Tao , Dai Fang
Published: January 2023

An interactive artificial ecological optimization algorithm (SIAEO) based on environmental stimulus and competition mechanism was devised to find the solution of complex calculation and be apt to get bogged down in local optimum in virtue of the sequential execution of consumption and decomposition stages in artificial ecological optimization algorithm. Firstly, the environmental stimulus defined by population diversity makes the population interactively execute the consumption operator and decomposition operator to abate the inhomogeneity of the algorithm. Secondly, the three different types of predation modes in the consumption stage were regarded as three different tasks, and the task execution mode was determined by the maximum cumulative success rate of each individual task execution. Furthermore, the biological competition operator is recommended to modify the regeneration strategy, so that the SIAEO algorithm can give consideration to the exploitation in the exploration stage, break the equal probability execution mode of the AEO, and promote the competition among operators. Finally, the stochastic mean suppression alternation exploitation problem is introduced in the later exploitation process of the algorithm, which can tremendously heighten the SIAEO algorithm to run away the local optimum. A comprehensive comparison between SIAEO and other improved algorithms is performed on the challenging CEC2017 and the latest CEC2019 test set. The optimization results state clearly that the SIAEO algorithm possesses excellent property in search efficiency, convergence accuracy and avoiding local optimization for both high and fixed dimensional questions. In the meantime, the SIAEO algorithm is utilized to resolve the four engineering majorization problems and high-dimensional K-means clustering problem, and the comparison results verify that the SIAEO algorithm is provided with good practical performance.
Analysis of MAP/PH(1),PH(2),PH(3)/2 Queueing System with Three Fluctuating Modes of Service, Standby Server, Working Breakdown, Impatient Behaviour of Customers, Vacations under Bernoulli Schedule and Phase Type Repairs
Authors: Govindan Ayyappan , Karthikeyan Thilagavathy
Published: January 2023

In this model, we consider the customers arrive according to Markovian Arrival Process (MAP) and their three fluctuating modes of service and repair process of both servers are based on phase-type (PH) distributions. While the main server-1 is offering any one of the modes of service who may affect by breakdown immediately go for phase-type repair process at that moment the standby server will interrupt the main server-1 and carry over the service process up to the phase-type repair completion of main server-1. Likewise, the main server-2 also caused by breakdown while offering any one of the modes of service to customers but the main server-2 has a capacity to provide service at the slower rate for the interrupted customer only before move to the phase-type repair process for rejuvenation due to the concept of working breakdown. At every service completion epoch, the main server-1 has an option to move forward to vacation or else remain in the system to offer service to next customer who is next in the queue. If both the server’s are unavailable in the system, the waiting customers in the queueing line may renege from the system because of impatient behaviour. Using matrix analytic method, we examine the steady-state probability vector, busy period and waiting time distribution. Furthermore, we illustrated some of the numerical and graphical representations of the proposed model.
Mathematical Model for the Quantification of Pulmonary and Intrapulmonary Arteriovenous Anastomoses Blood Flow
Authors: Vanni Rosalba
Published: January 2023

Background: Accurately quantifying blood flow through a shunt vessel is vitally important, because
shunt prevents gas exchange and can provide a pathway for emboli that bypass the pulmonary
microcirculation. Some current techniques allow an approximate estimate of the pulmonary shunt
and present technical and evaluative difficulties that can compromise the result.
Objectives: To develop a mathematical model, based on important chemical-physical laws, for the
precise calculation of pulmonary blood flow (Qp), intrapulmonary arteriovenous anastomoses blood
flow (QIPAVA) and then validate it.
Methods: Some experimental data, obtained from healthy subjects, were input into the model.
Results: Qp and QIPAVA were precisely calculated at rest and at moderate (50% of VO2max) and heavy exercise (90% of VO2max) in both normoxia (FIO2 = 0.2093) and acute hypoxia (FIO2 = 0.125).
In normoxia under heavy exercise, Qp decreased slightly (97.56% of Qt), and QIPAVA represented
2.44% of Qt.
Instead, in hypoxia at heavy exercise, Qp decreased significantly (85.25% of Qt), and QIPAVA
increased significantly (14.75% of Qt).
It was possible to demonstrate a negative contribution of QIPAVA directly to gas exchange efficiency
and identify incorrect Qt measurements.
Conclusions: This model is precise because composed of equations which describe the real
representation of gas exchange and therefore of universal application.
Qp differs significantly from Qt under some physiological conditions already in healthy subjects.
The use of this model will allow research a general advance in the understanding of this critical
biological function and in clinical practice a precise and early detection of the pathology.

Purpose. The commitment of multidisciplinary teams in antimicrobial stewardship programs (ASPs) is often inadequately considered, especially in surgical wards. We wanted to evaluate clinical, microbiological, and pharmacological outcomes before and after the implementation of an ASP in the Vascular Surgery ward of Fondazione IRCCS Policlinico San Matteo, a tertiary care hospital in Pavia, Italy.
Methods. This was a quasi-experimental quality-improvement study. The antimicrobial stewardship activity was conducted twice a week for 12 months and consisted of both prospective audit and feedback of all the ongoing antimicrobial prescriptions by the infectious diseases’ consultants and educational meetings for the healthcare workers of the Vascular Surgery ward. For comparison between the study periods, Student t test (Mann-Whitney test for skewed distributions) was used for quantitative variables (ANOVA or Kruskall-Wallis for >2 groups respectively), and Pearson’s chi-squared test (Fisher exact test where appropriate) for categorical variables. 2-tailed tests were used. P-value significance cut-off was 0.05.
Results. During the 12-month intervention period, among a total number of 689 patients, 186 prescriptions were revised, mostly leading to de-escalating an ongoing antimicrobial therapy (39, 20.97%). A statistically significant reduction in isolates of carbapenem-resistant Pseudomonas aeruginosa (p-value 0.003) and the absence of Clostridioides difficileinfections were reported. No statistically significant changes were observed in terms of length of stay and all-cause in-hospital mortality. A significant decrease in the administration of carbapenems (p-value 0.01), daptomycin (p-value <0.01) and linezolid (p-value 0.43) was registered. A significant reduction in antimicrobial costs was also observed.
Conclusions. The implementation of a 12-month ASP brought significant clinical and economic results, highlighting the benefits of a multidisciplinary teamwork.

The aim of this research work is to simultaneously evaluate the effects of inhomogeneous plastic strain-induced and anisotropy on frictional behavior. The studied material is the cold-rolled steel grade DC06EK intended for sheet metal forming. To achieve this work, stretched and unstretched DC06EK strips following different rolling directions (0°, 45° and 90°) with different levels of equivalent plastic strain were used in microscratch tests. The findings show that the calculated coefficient of friction (COF) decreases as a function of the equivalent plastic strain for different rolling directions. The COF have a clear trend lines of regression except in the case for 45°. Trend lines of the COF following 0° and 90° converge to very closely values, since the effect of anisotropy disappears with the increase in the level of plastic strain.

Epigenomics in stress tolerance of plants under the climate change
Authors: Kumar Mithlesh , Rani Kirti , Goswami Parth
Published: January 2023

During development and environmental stresses, plants experience genome-wide epigenetic alterations that are typically associated with differentiation in transcriptional gene expression.
An epigenome is the aggregate of a cell's biochemical modifications in its nuclear DNA, post-translational changes in histones, and differences in non-coding RNAs' biogenesis. Differences in gene expression that take place without any change in the underlying nucleotide sequence are frequently caused by these changes. Chromatin remodelling that can epigenetically dictate particular transcriptional outputs and change the function/activity of the genome include post-transcriptional histone modifications, variations in histone proteins, DNA methylation, and activity of non-coding RNA. Epigenetic marks have a significant impact on how plants respond to environmental challenges, and recent developments in the field of major crop "-omics" have made it easier to identify these marks. The phenotypic plasticity of the organism is impacted by the epigenomic alterations, which are dynamic in response to any endogenous and/or external stimuli. After the stress is withdrawn, both changes in gene expression and epigenetic alterations may quickly return to their pre-stress states. Few epigenetic alterations, which have been related to acclimatisation, adaptation, and the evolutionary process, might be retained, though. For better use of genetic resources, epigenome engineering may be used to improve plants' ability to withstand stress. In this chapter, we have outlined recent epigenetic studies that may be crucial for enhancing crop resilience and adaptation to environmental changes, ultimately resulting in the development of stable climate-smart crops.

A digital business model is a way of generating value based on the creation of client advantages using digital technology. The goal of the digital solution is to provide a significant advantage that customers are willing to pay for. For businesses facing digital disruption and digitization, developing digital business models is a crucial responsibility. A global platform for communication, the Internet is rapidly being utilized as a cutting-edge tool for product and service marketing. A competitive threat to conventional retail establishments, online digital market platforms have many benefits over traditional shopping methods. Consumers are quickly embracing internet shopping around the world, and Ethiopia is no exception. Online digital market platform marketers and retailers can further expand their marketing strategies to draw in and keep customers in order to gain a competitive edge globally if they are aware of the elements influencing consumers' purchasing intentions. Due to the scarcity of published research on the variables influencing Ethiopian consumers' intention to purchase online, there is a conceptual gap in the literature on online digital marketing. By identifying the crucial variables impacting Ethiopian consumers' desire to purchase on online digital market platforms, this study aims to close this conceptual gap in the context of online market platform purchasing. The information was gathered from 100 Ethiopian, Addis Ababa University, final year engineering students using a self-administered 5-point Likert scale questionnaire. The partial least square structural model (PLS-SEM) technique was used to examine the data. The results of this study highlighted five crucial decision-making elements that have an impact on Ethiopian consumers' intention to buy on online digital market platforms including Website Design, Perceived Usefulness, Perceived Ease of Use, Trust, and Subjective Norm. With the use of this information, manufacturers, online marketers, and retailers can create effective market strategies, enhance technology, and make smart marketing choices that will help them gain global competitive advantage.
A Randomized Algorithm for Finding Local Maximum Cuts
Authors: Gao Lunshan
Published: January 2023

This paper describes a new randomized algorithm for calculating local maximum cuts of the maximum cut problems in graph theory. The new algorithm transforms the maximum cut problem into a new form by using fuzzy logic technique. The transformation enables the algorithm to use the first-order derivative method to find optimal values for discrete non-linear optimization problems. This paper proves that the solution of the new algorithm satisfies the ϵ−δ condition. The algorithm converts decimal solution points to integer solution points by using the defuzzification technique. This paper also proves that the defuzzification maintains the local maximum value. The new algorithm is compared with IBM ILOG CPLEX. The numerical experiments indicate that the performance of the new algorithm is better than that of IBM ILOG CPLEX for finding local maximum cuts.
Ensemble of Population-Based Metaheuristics With Exchange of Individuals Chosen Based on Fitness and Lifetime for Real Parameter Single Objective Optimization
Authors: Zhu Xuanyu , Ye Chenxi , He Luqi , Zhu Hongbo , Chi Tingzi
Published: January 2023

Real parameter single objective optimization has been studied for decades to find the best decision vector to minimize (or maximize) an objective multi-dimension function. In recent, a new setting is proposed and applied in this field based on the consideration that solving difficulty scales exponentially with the increase of dimensionality. Under the new setting, Differential Evolution (DE) still outstands in performance as before. Meanwhile, a new type of population-based metaheuristic - Gaining-Sharing Knowledge based algorithm (GSK) becomes a dark horse. Furthermore, ensemble of the above two types of algorithm - APGSK-IMODE - is proposed in literature. In this paper, we change the scheme for executing communication between the two constituent algorithms - APGSK and IMODE, and propose APGSK-IMODE-II. In our experiment, our algorithm is compared with state-of-the-art algorithms. Experimental results show that our APGSK-IMODE-II is very competitive.
