Venoms have traditionally been studied from a proteomic and/or transcriptomic perspective, often overlooking the true genetic complexity underlying venom production. The recent surge in genome-based venom research (sometimes called “venomics”) has proven to be instrumental in deepening our molecular understanding of venom evolution, particularly through the identification and mapping of toxin-coding loci across the broader chromosomal architecture. Although venomous snakes are a model system in venom research, the number of high-quality reference genomes in the group remains limited. In this study, we present a chromosome-resolution reference genome for the Arabian horned viper (Cerastes gasperettii), a venomous snake native to the Arabian Peninsula. Our highly-contiguous genome allowed us to explore macrochromosomal rearrangements within the Viperidae family, as well as across squamates. We identified the main highly-expressed toxin genes compousing the venom’s core, in line with our proteomic results. We also compared microsyntenic changes in the main toxin gene clusters with those of other venomous snake species, highlighting the pivotal role of gene duplication and loss in the emergence and diversification of Snake Venom Metalloproteinases (SVMPs) and Snake Venom Serine Proteases (SVSPs) forCerastes gasperettii. Using Illumina short-read sequencing data, we reconstructed the demographic history and genome-wide diversity of the species, revealing how historical aridity likely drove population expansions. Finally, this study highlights the importance of using long-read sequencing as well as chromosome-level reference genomes to disentangle the origin and diversification of toxin gene families in venomous species.
Accelerating sustainable consumption by putting “simplicity” and consumer neuroscience to work: a conceptual framework
Authors: Khubchandani Salim , Menon Preetha , Raman Ramakrishnan
Published: July 2024

Purpose

Sustainable consumption has far-reaching implications globally, with promotion of sustainable consumption also identified as one of the sustainable development goals (SDGs). Hence, there is a need for relevant information to guide consumer buying decisions. Eco-labels have been created to serve as one of the key communication platforms for this purpose, but studies indicate low levels of comprehension. Hence this paper proposes a conceptual framework using established neuroscience theories and principles to address this topic of significance.

Design/methodology/approach

The “Simplicity Principle” propagates that simpler explanations find place over complex ones. Also, the Dual System Theory focuses on the two systems, intuitive System 1 and cognitive System 2, used by the brain to process information. We spotted a research gap here and leveraged these theories and drew from several earlier studies to propose a framework that presenting information in a “simple” manner on eco-labels would accelerate sustainable consumption.

Findings

System 1 works to reduce cognitive process and load on System 2, influencing overall choice and purchase decision. System 2 capacity requires the need to minimize cognitive load through processing simpler messages. Quick processing of information by System 1 generates impressions, attention and attitude. Once accepted by System 2, these often remain unchanged unless necessary and invariably turn into beliefs and voluntary action. Simplicity leverages speed and effortless processing ability of System 1, reducing effort of cognition by System 2 and enabling a decision (to purchase “green”).

Practical implications

Sustainability and sustainable consumption are matters of social and environmental concern and significance. This framework proposes the need for policymakers and businesses to consider adopting the “simplicity” approach in promoting sustainable consumption through bridging the vital gap in the understanding of eco-labels by consumers. There are implications and opportunities for researchers to conduct empirical research across different categories to validate this framework.

Originality/value

While several methods have been explored and implemented, given the significance of sustainability and sustainable consumption, eco-labels suffer from lack of comprehension, thus affecting adoption by consumers. Applying fundamental neuroscience principles of “simplicity” seems to have been overlooked so far toward addressing this gap. This framework proposes that applying “simplicity” to stimuli such as eco-labels and communications be considered to address and correct the situation and help to accelerate sustainable consumption.
Carbon reduction effect of digital finance in China: based on household micro data and input-output model
Authors: Lv Yongbin , Jia Ying , Sang Chenying , Sun Xianming
Published: July 2024

Purpose

This study investigates the causal relationship and mechanisms between the development of digital finance and household carbon emissions. Its objective is to explore how digital finance can influence the carbon footprint at the household level, aiming to contribute to the broader understanding of financial innovations' environmental impacts.

Design/methodology/approach

The research combines macro and micro data, employing input-output analysis to utilize data from the China Household Finance Survey (CHFS) for the years 2013, 2015, 2017, and 2019, national input-output tables, and Energy Statistical Yearbooks. This approach calculated CO2 emissions at the household level, including the growth rate of household carbon emissions and per capita emissions. It further integrates the Peking University Digital Financial Inclusion Index of China (PKU-DFIIC) for 2012–2018 and corresponding urban economic data, resulting in panel data for 7,191 households across 151 cities over four years. A fixed effects model was employed to examine the impact of digital finance development on household carbon emissions.

Findings

The findings reveal that digital finance significantly lowers household carbon emissions. Further investigation shows that digital transformation, consumption structure upgrades, and improved household financial literacy enhance the restraining effect of digital finance on carbon emissions. Heterogeneity analysis indicates that this mitigating effect is more pronounced in households during the nurturing phase, those using convenient payment methods, small-scale, and urban households. Sub-index tests suggest that the broadening coverage and deepening usage of digital finance primarily drive its impact on reducing household carbon emissions.

Practical implications

The paper recommends that China should continue to strengthen the layout of digital infrastructure, leverage the advantages of digital finance, promote digital financial education, and facilitate household-level carbon emission management to support the achievement of China's dual carbon goals.

Originality/value

The originality of this paper lies in its detailed examination of the carbon reduction effects of digital finance at the micro (household) level. Unlike previous studies on carbon emissions that focused on absolute emissions, this research investigates the marginal impact of digital finance on relative increases in emissions. This method provides a robust assessment of the net effects of digital finance and offers a novel perspective for examining household carbon reduction measures. The study underscores the importance of considering heterogeneity when formulating targeted policies for households with different characteristics.
Exploring the mediating role of job and life satisfaction between work–family conflict, family–work conflict and turnover intention
Authors: Poulose Jeanne , Sharma Vinod
Published: July 2024

Purpose

This study investigates the influence of work-to-family and family-to-work conflict on turnover intention (career break), mediated through job and life satisfaction among Indian women in the service sector, using role conflict theory as the base.

Design/methodology/approach

A total of 421 usable responses from women who had taken a career break were collected using a 36-item scale from six major metro cities in India through social and digital media platforms. A purposive-cum-snowballing sampling method was adopted. The hypotheses were tested using structural equation modeling (SEM) through AMOS.

Findings

Findings suggest that job satisfaction (JS) is a significant predictor of turnover intention, both when work spills into the family domain, and family responsibilities spill into the work domain, thereby confirming the mediating influence of JS. Interestingly, life satisfaction (LS) only seems to mediate between inter-domain conflict and turnover intention partially.

Research limitations/implications

This is a descriptive study, and is thereby limited in terms of its generalizability, specifically as it included respondents only from six major metro cities in India.

Practical implications

The extended work-family conflict model could help managers structure organizational interventions that support women to deal with the challenges of managing the demands of both work and family domains, thereby reducing the negative influence on JS. Such initiatives could help reduce career breaks among women.

Originality/value

We explored the cause of career breaks among Indian urban women employed in the service sector, using the extended model of inter-role conflict and their attitudes towards both life and job.
Achieving sustainability through green human resource management practices and environmental orientation fit: a multilevel modeling
Authors: Gilal Faheem Gul , Nawaz Asif , Riaz Amir , Channa Khalil Ahmed , Jahanzeb Agha
Published: July 2024

Purpose

The study investigates how Green Human Resource Management (GHRM) influences employee green behavior and wellbeing. It specifically explores the impact of organizational-level GHRM on employees' organizational citizenship behavior towards the environment (OCBE) and subjective wellbeing, mediated by psychological contract fulfillment (PCF). The study also examines the moderating effect of environmental orientation fit.

Design/methodology/approach

The data were collected from two sources: managers (N = 67) and employees (N = 217) of readymade garment exporting firms in Pakistan. The analysis was conducted using HLM multilevel modeling software.

Findings

The findings indicate that PCF acts as a significant mediator in the association between GHRM, OCBE, and employee wellbeing. Furthermore, the results suggest that the positive impact of GHRM on PCF is more pronounced when there is a higher alignment with environmental orientation, compared to when the fit with environmental orientation is low.

Originality/value

To the authors' knowledge, this study is the first to explore the impact of organizational-level GHRM on employee-level organizational citizenship behavior towards the environment and their subjective wellbeing, particularly within the context of readymade garments. Furthermore, this research endeavors to offer managers a heightened understanding of the potential role of GHRM in fostering organizational citizenship behavior.
The relevance of legal requirements in the going public process: the discretionary decision of adopting an audit committee
Authors: Castaño Leticia , Farinós José E. , Ibañez Ana M.
Published: July 2024

Purpose

We study the role of having an audit committee (AC) as a signal of firm quality and as a monitoring device of the information quality contained in the listing prospectus.

Design/methodology/approach

Ordinary Least Squares regressions are used to examine the association between the presence of an audit committee and (1) the initial return (IR), and (2) the earnings forecast error in the listing prospectus in a sample of 55 Real Estate Investment Trusts that went public on the BME Growth market during 2013–2022. Heckman two-step estimation procedure to correct for endogeneity and bootstrap are used for robustness.

Findings

We show that IR and earnings forecasts are significantly affected by the presence of AC. The IR is higher and the earnings forecast included in the prospectus are of higher quality in firms with AC.

Practical implications

Our research provides (1) managers with new tools when deciding on their corporate governance structure in the listing process, (2) specific evidence for regulators on the role played by ACs in the process of going public, which may be useful in the context of the ongoing regulatory changes regarding admission processes in Europe, and (3) society with a sign that AC can enhance investor and public confidence in financial markets and foster a more stable and transparent investment environment.

Originality/value

The adoption of an AC is voluntary in this market, so this discretionary decision provides an exceptional opportunity to conduct such an analysis. Additionally, this issue has not been previously analysed in Europe.
“Virtual bonds and actual transactions”: investigating the impact of virtual influencers' credibility on buying behavior through virtual engagement
Authors: Agnihotri Durgesh , Chaturvedi Pallavi , Tripathi Vikas
Published: July 2024

Purpose

This research makes an effort to empirically investigate the role of source credibility theory (SCT) in the prevailing modern influencer marketing context by establishing an association between virtual influencers ((VIs) non-human) and the buying behavior of their followers. It further provides insights into the mediating role of virtual engagement on the affiliation between VIs’ credibility and the buying behavior of followers.

Design/methodology/approach

The study used structural equation modeling (CB-SEM) to assess data from a survey conducted online of 538 participants (Instagram followers of virtual influencers).

Findings

The results reveal that source credibility dimensions significantly affect followers’ buying behavior in the context of VIs except the trustworthiness dimension. However, mediation analysis has shown that virtual engagement substantially mediates between source credibility dimensions including trustworthiness.

Practical implications

The study highlights the value of the credibility of VI and its alignment with the followers’ buying behavior. The study provides valuable inputs for the brand managers as the credibility of the VI can be effectively leveraged in implementing strategies to encourage their followers/consumers on social media platforms to purchase the goods/services they endorse.

Originality/value

The study overcomes the shortcomings of recent studies by empirically investigating the affiliation between VIs’ credibility and followers’ buying behavior through Instagram. The study uniquely extends the potential of SCT in the context of non-human VIs.
The impact of the COVID‐19 public health response on service demand and patient perceptions in a tertiary Australian gynaecology oncology unit
Authors: Yasin Nooraishah , Yu Michael , Jones Kristen , Woolfield Anne , Hughes Ian , Nascimento Marcelo , Green Helen
Published: July 2024

Introduction

The public health response (PHR) to the COVID‐19 pandemic significantly disrupted healthcare services worldwide. Our hospital, a major tertiary centre, is a unique two‐state service across Queensland and New South Wales (NSW).

Objective

The primary objective is to describe changes in service demand and delivery in our hospital resulting from the COVID‐19 PHR. The secondary objective is to investigate patient perceptions of this impact.

Materials and Methods

We performed a retrospective interrupted time series analysis and a population‐based survey to examine patient perceptions of the impact of the COVID‐19 PHR. The study periods were demarcated by the initiation of the COVID‐19 PHR on 1 March 2020 with the ‘pre’ and ‘during’ COVID‐19 periods defined as the 12 months before and after this date respectively.

Results

More patients were seen during the COVID‐19 PHR period. The number or stage of cancer diagnoses was not different (P > 0.05). There was evidence (P = 0.03) of an increase in overall occasions of service and fewer failed attendances (P = 0.005). Fewer surgeries were performed on NSW patients (P = 0.005). The survey response rate was 19.3% (n = 185) with 48% stating that COVID‐19 had negatively affected their emotional wellbeing. More participants from NSW than Queensland identified border closures as the most significant impact of the COVID‐19 PHR.

Discussion

The COVID‐19 PHR resulted in an unexpected increase in unit service demand and delivery. The necessary implementation of telephone appointments, while less preferred by patients, sustained service requirements. Cross‐border tertiary healthcare services should consider the significant impact of border restrictions on patient wellbeing.
Racial equity, reflection, and organizational change in museums
Authors: Feinstein Noah Weeth , Hsu‐Borger Esther , Bequette Marjorie B. , Garibay Cecilia , Jones‐Rizzi Joanne , Ronning Evelyn Christian , West Corinna P.
Published: July 2024

When are equity conversations more than “just talk?” This article draws on qualitative data from two interconnected NSF‐funded studies about racial equity in museums to explore the relationship between organizational reflection and organizational change. In one study, researchers interviewed staff from 29 museums that hosted the traveling exhibition RACE: Are We So Different? In the other, staff from of the Science Museum of Minnesota (SMM) used action research to challenge their own racial equity norms and policies during and after the permanent installation of RACE. Our results reveal a sharp contrast between reflection that is strategically undertaken to produce organizational change and reflection that emerges opportunistically in response to a traveling exhibition. Yet they also show how, in rare cases, museums were able to exploit the opportunities presented by a traveling exhibition to develop and sustain equity‐oriented reflection over time.

Neurocysticercosis (NCC), a major cause of global acquired epilepsy, results from Taenia solium larval brain infection. T. solium adult worms release large numbers of infective eggs into the environment contributing to high levels of exposure in endemic areas. This study identifies T. solium proteins in the sera of individuals with and without NCC using mass spectrometry to examine exposure in endemic regions. Forty‐seven patients (18–51 years), 24 parenchymal NCC (pNCC), 8 epilepsy of unknown aetiology, 7 glioma, 8 brain tuberculoma, and 7 healthy volunteers were studied. Trypsin digested sera were subject to liquid chromatography–tandem mass spectrometry and spectra of 375–1700 m/z matched against T. solium WormBase ParaSite database with MaxQuant software to identify T. solium proteins. Three hundred and nineteen T. solium proteins were identified in 87.5% of pNCC and 56.6% of non‐NCC subjects. Three hundred and four proteins were exclusive to pNCC sera, seven to non‐NCC sera and eight in both. Ten percent, exhibiting immune‐modulatory properties, originated from the oncosphere and cyst vesicular fluid. In conclusion, in endemic regions, T. solium proteins are detected in sera of individuals with and without pNCC. The immunomodulatory nature of these proteins may influence susceptibility and course of infection.
Exploring the practical relevance of food aid rationales in Belgium: Lessons from applying in‐kind transfer valuation methods
Authors: Hermans Karen , Marchal Sarah
Published: July 2024

Charitable food aid is gaining new relevance in mature welfare states: the number of beneficiaries increases while the subsidization by and collaboration with the state intensifies. We distinguish three rationales to this further institutionalization: poverty mitigation, and ecological and paternalistic reasonings. In this explorative study we assess the validity of these rationales in the actual set‐up of food aid in Belgium. Specifically, we apply three different in‐kind transfer valuation methods (production cost, market and recipient value) to robustly estimate the value of food aid. This mixed‐methods study builds on purpose‐collected field work data on distributed food aid packages, Household Budget Survey data on common consumption patterns, and a thorough document analysis into food aid spending data. The estimated value of food aid strongly depends on the valuation method: the annual total value of food aid in Belgium ranges from 57 to 148 million euros. Importantly, we observe a discrepancy between prevalent rationales and the actual set‐up of food aid. In contrast to the ecological reasoning of fighting food waste, large part of the total value stems from new food purchases, which involve paternalistic choices. Yet, the composition of food aid packages only partly complies with nutritional recommendations. Moreover, they do not fully meet recipients' preferences and needs, which generates a welfare loss. Food aid may nonetheless seem efficient from a policy perspective: a ‘charity multiplier effect’ appears to translate the government production cost in a higher market value. Still, its unpredictable and mismatched nature likely reduces its poverty mitigating effect.
The intergenerational transmission of financial disadvantage across Europe
Authors: Dewilde Caroline
Published: July 2024

Growing income and wealth inequality have rekindled interest in questions of social mobility versus intergenerational persistence. Specifically at the low‐end of the inequality distribution, rising poverty risks amongst working‐age households have raised concerns regarding later‐life consequences of childhood poverty. This paper investigates cross‐country and ‐cohort variations in the intergenerational transmission of financial disadvantage, by pooling cross‐sections from EU‐SILC (2005‐2011‐2019) for 31 European countries. Similar to previous research, adolescent financial disadvantage contributes significantly to income poverty risks in adulthood. In only about half of European countries, such impacts are explained by close relationships between parental family structure and adolescent financial disadvantage, or mediated by labour market‐related status attainment from parents to children. Next, compared with older cohorts, for younger respondents coming of age in the era of enhanced globalization and dualization since the 1990s, and during the post‐financial crisis and austerity years, a trend towards enhanced stratification of current poverty with regard to adolescent financial disadvantage emerges. Multilevel analyses based on these younger cohorts indicate that more generous active (outsider spending) and passive (social exclusion spending) welfare benefits aimed at compensating poorer households for the consequences of labour market and welfare state dualization significantly mitigate current income poverty of those who experienced financial disadvantage in adolescence. Welfare reforms implying reductions in social spending disproportionally affecting ‘outsider’‐households (intended or unintended) may therefore be costly in the long run, as the intergenerational transmission of financial disadvantage might intensify.
Teaching Prayers for the Guidance of Mu’allaf (Newly Riveted Muslim): An Android Application Design and Development Research
Authors: Hashim Suhaizal , Abu Yazid Nur Najihah , Che Lah Noor Hidayah
Published: July 2024

Mu'allaf is a call for non-Muslims who hope to convert to Islam or inherited Islam whose faith still needs to be supported and strengthened. It is the responsibility of Muslims to give support and strength to Mu'allaf who are now considered brothers in religion, especially in the form of welfare, moral, financial, and learning assistance. When a non-Muslim has entered the religion of Islam, he must learn the ritual of prayer and perform it to the best of his ability as a person who has just learned Islam. However, interpreting these prayers with a guidebook alone is insufficient; considering that they need additional help in terms of words and actions. The Prayers Learning Application is a new method to learn prayers that are taught digitally using the portable platform of Android. Thus, the purpose of this study is to design and develop an android application for teaching prayers for the guidance of Mu’allaf. This android application includes multimedia elements to attract and help users better understand delivering prayers. The study's methodology was based on design and development research (DDR) and Waterfall Model was used as a guide in developing this android application. Adobe Animate 2021 was chosen as a development platform, using Action Script 3.0 as the programming language to develop this android application. This application consists of four modules which are Prayer Note, Prayer Time, Simply Prayer, and Prayer Videos. Three experts from a local higher education institution were appointed to evaluate this android application in terms of its functionality through content, interface, and interaction design. The data analysis is acquired in the form of frequency and percentage. Results revealed that this android application is suitable for new learners, which is the mu'allaf community to learn about prayers. In addition, this android application is expected to provide a positive impact in terms of functionality and usability in the future, especially in teaching prayers for the guidance of Mu’allaf. The application of mobile learning is indeed providing a very useful opportunity to deliver Islamic knowledge widely

Audio-Visual Learning in Secondary School: A Review of Advantages and Challenges in Education
Authors: Ahmad Maisarah , Abd Halim Noor Dayana
Published: July 2024

The Industrial Revolution 4.0 (IR) is an impetus for the use of more advance technology in the education setting. Alongside the changes taking place because of it, teachers too need to evolve. As the main player of any teaching and learning session (PdP), their role is not only to modify students’ behaviour but also actualise educational goals. Both of which can be helped with the use of technology-based materials and mediums. Audio media is a media in the form of sound that requires listening abilities, whereas visual media is materials in the form of images or pictures that do not require listening skills but do require viewing skills. The selection of one of these media as a learning medium results in one-way and ineffective listening. On the other hand, audio-visual media is an intermediary media which combines seeing and listening skills that help students acquire knowledge, skills, and attitudes to achieve learning goals. Therefore, this paper will look at the literature review on the potential of audio-visual material-assisted learning in education and explore its advantages and challenges at secondary school level. The review demonstrates the advantages of implementing audio-visual materials in multiple fields of education. Using Boolean search techniques, a literature search was produced from numerous databases while searching for terms related to audio-visual teaching and learning. This study reviewed ten research papers from 2018 to 2022 using a systematic analytical approach to produce a comprehensive analysis based on specific criteria.This study summarizes the advantages and challenges of learning with the help of audio-visual materials. It is reported that the use of audio-visual materials helps to increase students’ motivation, ensure students’ active participation, engage students’ attention, create better learning atmosphere, increase teacher innovation and creativity, and ultimately resulted in increase of learning delivery effectiveness. However, it doesn’t come without a challenge. Preparing such materials is timeconsuming, costly and requires high technical skills which affects teachers’ motivation. As such, this paper can help educators see how the application of audio-visual materials in the educational world benefits students. In addition, educators can also identify challenges or constraints that need to be paid attention to if this material is to be used in PdP in the future.

Published: July 2024

A devastating fire and explosion occurred on an onshore atmospheric storage tank on Malaysia's Peninsular. Three of the storage tanks were damaged and collapsed as a result of the disaster. As a result of the intricacy of the operation, method, and human irregularity, a major fire and explosion were caused. This study addressed a TRIZ and ISHIKAWA combo to seek the probable root causes of the incident fire and explosion at an atmospheric storage tank and justified a trustworthy source of accident causers. A TRIZ, ISHIKAWA, and forensic engineering techniques were used to establish that there was a welding process with the existing and engulfing of the combustible gaseous dispersion to atmosphere that was formed from crude oil. Hence, these lethal mixtures of flammable gases and wielding activity resulted in a fire and explosion tragedy in the region. As a result, this study will provide major signs or points of caution and insight into the possibility of fire and explosion being avoided at an early stage of the refinery process.

Finite Element Study on Mechanical Properties of The Normal and Transverse Fracture Bones – A Computational Simulation
Authors: Mohamad Mohd Riduan , Nazilatul Furqoni
Published: July 2024

There are lots of cases of injury or trauma that can cause broken or cracked bones. Long treatment can be more dangerous when combined with some of the diseases they have. Despite this, there is still not much research on the mechanical properties of bone, especially in the elderly. To develop bone tissue engineering and the design of bionic bones, it is essential to understand the mechanical properties and microscopic failure mechanisms of bones. Proper bone function also depends on the mechanical properties of the bone. The purpose of this study is to develop the three-dimensional bone model for finite element analysis simulation and examine the mechanical behavior of two different types of bone (normal and non-displaced transverse fracture bone) through ANSYS Workbench. The 3D bone model design of normal and cracked bone was imported, analyzed, and simulated in ANSYS with varying loads applied. To get the parameter of mechanical characteristics of bones to result. Application of finite element method using ANSYS Software as a computational technique that uses continuum mechanics theories to solve biomedical engineering problems may require the accurate analysis of the mechanistic properties of human bone. There was no significant difference in elastic modulus between normal and fractured bone. The maximum Young's modulus was found at 8.225×10-7 with a minimum of 4.095×10-5. Despite this, the shear strain and stress hold a huge gap in the maximal and minimum position of both types of bone. Certainly, transverse fracture bone got the highest number of total deformations. The normal bone got 0.00023607 m for total deformation, alternatively, 0.00031965 m occurs in transverse fracture when the greatest load is performed.  This clearly states, that cracked bone has a greater risk of failure and stiffness especially in elderly people. These mechanical properties findings of fractured bone are considered suitable for further development, especially in the prevention and treatment to decrease the revision of critical surgery in the future.

ADVANCEMENTS IN SUPERSONIC FLIGHT CONTROL: REVIEW OF CAVITY FLOW IMPACT AND INTEGRATION OF ACTIVE AND PASSIVE CONTROL MECHANISMS
Authors: Balakrishnan Sheysshindth , Abd. Rahim Abu Talib  , Mat Shabudin , Abdul Hamid Mohd. Faisal
Published: July 2024

This review paper explores the challenges of supersonic flight, specifically focusing on the impact of cavities on flight dynamics and the effectiveness of various control mechanisms. The paper addresses three primary objectives: understanding cavity-induced effects during supersonic flight, evaluating the effectiveness of active and passive cavity flow control techniques, and exploring the integration of both approaches for optimized control. Cavities, or recessed areas on aircraft surfaces, can cause complex shock-wave patterns during supersonic flight, leading to problems like increased drag, reduced controllability, and heightened acoustic emissions. The paper aims to highlight the the mechanisms underlying these cavity-induced phenomena by analyzing existing research and shedding light on their effects on flight dynamics. The effectiveness of two distinct control strategies, active and passive, in managing cavity-related issues is investigated. Active control involves real-time adjustments using technologies like jets and feedback loops, while passive methods alter flow behavior through design features. The review examines the outcomes of research studies that have employed these techniques, providing an assessment of their individual merits and limitations. The paper also emphasizes the potential benefits of integrating active and passive control approaches to achieve a comprehensive solution for cavity-induced instabilities. By combining the strengths of both methods, this integrated approach promises improved stability, reduced drag, and enhanced overall flight performance. The review synthesizes findings from existing research, facilitating a comparison of outcomes, and offering a guide for future investigations into the synergistic application of active and passive controllers.

This paper evaluates the viability of employing paraffin wax including energetic additives as solid fuel in a hybrid rocket. In this paper, three distinct fuel compositions were used to compare the augmentation of the regression rate. Hybrid rockets combine the best characteristics of solid and liquid rockets, and they provide a multitude of advantages, such as safe handling and storage, a wider variety of fuel, a lower price, and enhanced dependability. However, it has a key drawback that hinders performance: a low regression rate. An earlier study found that doping the fuel with energetic additives such as aluminium, boron, hydrogen, and ammonia might increase the pace of regression. These nanoparticles will enhance evaporation and combustion efficiency, hence accelerating regression. According to the data, using aluminium increases regression rates by up to 21.2%, followed by using magnesium (19.9%), and iron (8.7%), which has the smallest increase in regression rates. According to this study, adding energetic materials to the fuel of hybrid rocket motors has improved the regression rate problem.
Wiener Index of Extended Fibonacci Cubes

The series of Extended Fibonacci cubes defined in terms of Fibonacci strings are classes of incomplete hypercubes. The Wiener index of a network, also known as the transmission of a network, is the sum of distances between all pairs of vertices in the network. It provides the average distance between any two nodes of the network. An embedding of a graph [Formula: see text] into a graph [Formula: see text] is a one-to-one mapping of [Formula: see text] into [Formula: see text]. Wirelength is a widely studied embedding parameter. In this paper, we determine the Wiener index of all cubes in the series of Extended Fibonacci cubes. We also find the wirelength of embedding a complete graph with a deleted edge onto the Extended Fibonacci cubes.

Pediatric chronic myeloid leukemia (pCML) is a rare malignancy accounting for only 2%–3% of all childhood leukemias. Due to this rarity, familiarity with pCML is limited among most pediatric practitioners, including even pediatric hemato‐oncologists. In low‐ and middle‐income countries (LMICs), limited financial resources and limited data specific to pCML represent obstacles that healthcare providers must face in diagnosing and treating this rare condition in children. The International CML Foundation (iCMLf) is improving outcomes for people with CML in these countries where resources, diagnostics, and access to medicines may be limited (https://www.cml-foundation.org/lmic-programs.html). Virtual meetings with the purpose of teaching participating pediatricians from LMICs of defined geographical regions were organised by the iCMLf in 2023. At a virtual meeting of the South Asia region, the case of a 14‐year‐old Indian boy was presented diagnosed with CML in a chronic phase complicated by priapism and loss of vision in his left eye due to hyperleukocytosis. Key aspects of this case are discussed in‐depth from the perspective of (i) a pediatric hemato‐oncologist practicing in a high‐income country, (ii) a pediatric hemato‐oncologist practicing in a LMIC, (iii) an adult CML hematologist, and (iv) from the iCMLf in improving the care of children with CML worldwide. Thus by discussing a multifaceted complicated case of pCML in written form as well as pointing to the pediatric module of the iCMLf Knowledge Centre will hopefully contribute to minimize existing knowledge gaps in a rare pediatric malignancy.

The objective of the work was to evaluate the effects of nicotinamide application via seed immersion on seed physiological quality and initial growth characteristics. Two experiments were carried out, in the laboratory (seed physiological potential) and another in a randomized block design, in a greenhouse (initial growth). Treatments consisted of immersion of seeds in six solutions with different concentrations of nicotinamide (0, 100, 200, 300, 400, and 500 mg·L−1). Characteristics related to primary root protrusion speed, average protrusion time, protrusion rate, and primary root length were evaluated under different temperature conditions (18°, 25°, and 35°C), and gas exchange, plant height, stalk diameter, number of leaves, aerial fresh weight, aerial dry weight, and root dry weight were evaluated. It was found that the use of nicotinamide, despite delaying the process of radicle protrusion, increases its development under stressful temperature conditions and results in an increase in gas exchange processes and gain in initial growth, mainly in the aerial part. Thus, it is concluded that the use of nicotinamide in maize seeds has the potential for use in stressful environments, as well as for obtaining greater initial growth, in which concentrations between 200 and 300 mg·L−1 are suitable for the crop.
Finite‐Time Adaptive Fuzzy Control for Stochastic Nonlinear Systems with Input Quantization and Actuator Faults
Authors: Kharrat Mohamed , Alhazmi Hadil
Published: July 2024

This study examines the problem of fuzzy adaptive finite‐time control for strict‐feedback stochastic nonlinear systems in the presence of actuator faults and quantization. The nonlinear functions inside the systems are approximated using fuzzy logic systems (FLS). Fuzzy approximation abilities are employed to develop an adaptive fuzzy finite‐time controller based on the backstepping design methodology and the Lyapunov function approach. It is shown that, despite quantization and unknown actuator faults, the closed‐loop system states stay bounded and the tracking error is confined to a small range close to equilibrium in finite time. The simulation examples are provided to illustrate the efficacy of the control strategy.
