  1. Fulltext Investigation of the dynamical structures of double-chain deoxyribonucleic acid model in biological sciences
    Yousaf MZ, Abbas M, Nazir T, Abdullah FA, Birhanu A, Emadifar H
    Sci Rep, 2024 Mar 17;14(1):6410.
    PMID: 38494490 DOI: 10.1038/s41598-024-55786-z
    The present research investigates the double-chain deoxyribonucleic acid model, which is important for the transfer and retention of genetic material in biological domains. This model is composed of two lengthy uniformly elastic filaments, that stand in for a pair of polynucleotide chains of the deoxyribonucleic acid molecule joined by hydrogen bonds among the bottom combination, demonstrating the hydrogen bonds formed within the chain's base pairs. The modified extended Fan sub equation method effectively used to explain the exact travelling wave solutions for the double-chain deoxyribonucleic acid model. Compared to the earlier, now in use methods, the previously described modified extended Fan sub equation method provide more innovative, comprehensive solutions and are relatively straightforward to implement. This method transforms a non-linear partial differential equation into an ODE by using a travelling wave transformation. Additionally, the study yields both single and mixed non-degenerate Jacobi elliptic function type solutions. The complexiton, kink wave, dark or anti-bell, V, anti-Z and singular wave shapes soliton solutions are a few of the creative solutions that have been constructed utilizing modified extended Fan sub equation method that can offer details on the transversal and longitudinal moves inside the DNA helix by freely chosen parameters. Solitons propagate at a consistent rate and retain their original shape. They are widely used in nonlinear models and can be found everywhere in nature. To help in understanding the physical significance of the double-chain deoxyribonucleic acid model, several solutions are shown with graphics in the form of contour, 2D and 3D graphs using computer software Mathematica 13.2. All of the requisite constraint factors that are required for the completed solutions to exist appear to be met. Therefore, our method of strengthening symbolic computations offers a powerful and effective mathematical tool for resolving various moderate nonlinear wave problems. The findings demonstrate the system's potentially very rich precise wave forms with biological significance. The fundamentals of double-chain deoxyribonucleic acid model diffusion and processing are demonstrated by this work, which marks a substantial development in our knowledge of double-chain deoxyribonucleic acid model movements.

  2. Fulltext Prosocial motives underlie scientific censorship by scientists: A perspective and research agenda
    Clark CJ, Jussim L, Frey K, Stevens ST, Al-Gharbi M, Aquino K, et al.
    Proc Natl Acad Sci U S A, 2023 Nov 28;120(48):e2301642120.
    PMID: 37983511 DOI: 10.1073/pnas.2301642120
    Science is among humanity's greatest achievements, yet scientific censorship is rarely studied empirically. We explore the social, psychological, and institutional causes and consequences of scientific censorship (defined as actions aimed at obstructing particular scientific ideas from reaching an audience for reasons other than low scientific quality). Popular narratives suggest that scientific censorship is driven by authoritarian officials with dark motives, such as dogmatism and intolerance. Our analysis suggests that scientific censorship is often driven by scientists, who are primarily motivated by self-protection, benevolence toward peer scholars, and prosocial concerns for the well-being of human social groups. This perspective helps explain both recent findings on scientific censorship and recent changes to scientific institutions, such as the use of harm-based criteria to evaluate research. We discuss unknowns surrounding the consequences of censorship and provide recommendations for improving transparency and accountability in scientific decision-making to enable the exploration of these unknowns. The benefits of censorship may sometimes outweigh costs. However, until costs and benefits are examined empirically, scholars on opposing sides of ongoing debates are left to quarrel based on competing values, assumptions, and intuitions.

    PLoS One, 2023;18(8):e0286112.
    PMID: 37616315 DOI: 10.1371/journal.pone.0286112
    Technology invention and implementation have resulted in long-term educational progress. This study aimed to identify the innovative strategies in determining the factors influencing in-service teachers' technology integration in China, focusing on the information and communication technology (ICT) integration. The sample consists of 685 in-service teachers. Four factors are found to influence in-service teachers' ICT integration: attitudes, self-efficacy, digital competence, and digital tools use. The results of the study utilizing the PLS-SEM approach demonstrated that all four factors have a substantial impact on in-service teachers' ICT integration and interact with each other. Meanwhile, attitudes, digital competence, and digital tools use have a mediating effect in this research. In addition, the study discussed the effects of gender, age, and teaching experience on influencing factors and ICT integration. This research provided beneficial insights for a successful design of instruction with ICT and contributed to innovative strategies for educational technology.

    Tao H, Rahman MA, Al-Saffar A, Zhang R, Salih SQ, Zain JM, et al.
    Work, 2021;68(3):853-861.
    PMID: 33612528 DOI: 10.3233/WOR-203419
    BACKGROUND: Nowadays, workplace violence is found to be a mental health hazard and considered a crucial topic. The collaboration between robots and humans is increasing with the growth of Industry 4.0. Therefore, the first problem that must be solved is human-machine security. Ensuring the safety of human beings is one of the main aspects of human-robotic interaction. This is not just about preventing collisions within a shared space among human beings and robots; it includes all possible means of harm for an individual, from physical contact to unpleasant or dangerous psychological effects.

    OBJECTIVE: In this paper, Non-linear Adaptive Heuristic Mathematical Model (NAHMM) has been proposed for the prevention of workplace violence using security Human-Robot Collaboration (HRC). Human-Robot Collaboration (HRC) is an area of research with a wide range of up-demands, future scenarios, and potential economic influence. HRC is an interdisciplinary field of research that encompasses cognitive sciences, classical robotics, and psychology.

    RESULTS: The robot can thus make the optimal decision between actions that expose its capabilities to the human being and take the best steps given the knowledge that is currently available to the human being. Further, the ideal policy can be measured carefully under certain observability assumptions.

    CONCLUSION: The system is shown on a collaborative robot and is compared to a state of the art security system. The device is experimentally demonstrated. The new system is being evaluated qualitatively and quantitatively.

    Marzan M, Islam DZ, Lugova H, Krishnapillai A, Haque M, Islam S
    Infect Drug Resist, 2021;14:519-533.
    PMID: 33603416 DOI: 10.2147/IDR.S289964
    Background: Antibiotics are lifesaving drugs, and inappropriate uses lead to the resistance that renders them ineffective. This study aims to understand knowledge, attitude, and practice (KAP) concerning antibiotic use and resistance among university students in Bangladesh.

    Methods: A cross-sectional study was performed from January to April 2020 among students at Jahangirnagar University (JU), Bangladesh. Purposive sampling was conducted through an in-person interview using a structured questionnaire. Students from the faculties of biological sciences and non-biology background were included. The univariate ordinal regression technique was used to analyze the relationship between predictors and good knowledge about the antibiotics. A two-tailed p-value was calculated to determine statistical association.

    Results: Out of 205 study participants, 92 and 113 responders were from biological science faculty and non-biology disciplines, respectively. Less than half of the students (42.4%) showed a good knowledge level (scores higher than 80%). Biology-background students possess better knowledge than non-biology students [odds ratio (OR) = 4.44, 95% confidence level (CL) (2.56, 7.70), p < 0.001]. A better attitude was noticed among all students. The self-medication rate was quite low, and more than 90% of students were found to consume antibiotics according to the physician's prescription. Lack of treatment adherence was recorded, and students admitted to stop-taking antibiotics when symptoms disappeared (48.67% biology and 36.26% non-biology). Multivariate regression analysis was unable to detect any significant association between self-medication and gender, student category or the level of knowledge about antibiotics.

    Conclusion: Students of biological science background possessed better knowledge indicating the importance of appropriate curriculum imparted in knowledge buildup. Introducing a short course about the risk and development of antibiotic resistance will grow the students' awareness to avoid the resistance phenomenon.

    Teoh SL, Sapri SRB, Yusof MRBM, Yahaya MF, Das S
    J Am Assoc Lab Anim Sci, 2020 09 01;59(5):512-518.
    PMID: 32600503 DOI: 10.30802/AALAS-JAALAS-19-000167
    Recently, the zebrafish has gained in popularity as a vertebrate animal model for biomedical research. Commercial zebrafish housing systems are available and are designed to maximize stocking density of fish for a given space, but these systems are expensive and purchasing them may not be feasible for emerging laboratories with limited funding. In this article, we describe the construction of a simple and affordable recirculating zebrafish housing system. This system can be constructed in 3 working days, with materials readily available in hardware stores. The cost for construction of the system was only 3,000 MYR (750 USD). The system consists of a water reservoir, a supply line that delivers water to the shelves holding the zebrafish tanks, and a drainage line that receives water from both the supply line and the shelves containing the fish tanks and returns this water to the reservoir. This system also has a 3-stage filtration process to ensure that clean water is delivered to the zebrafish tank. The system can house up to 360 zebrafish. This low-cost housing system may make research using zebrafish feasible some laboratories.

    Supervision and monitoring of practical students are among the pertinent components in the management of industrial training among students in institutions of higher learning (IPT) in Malaysia. The easiest way to monitor is by reporting such students’ daily activities in their logbooks. Due to the dispersal of offshore industries, it directly impacts to students, institution and industry such as management costs, wastes supervision time for travel and stresses other factors in managing industry supervision such as ongoing supervision, verification of customization of industry entities regarding needs and reduction of allocation by IPT. Thus, a new mechanism needs to be implemented by considering the advantages and benefits that can be developed throughout the use of information technology (IT). In conjunction with this circumstance, a Smart LogBook prototype has been developed to address the problems encountered in the supervision process of the industry training students as stated. A study of students’ perceptions of the Smart Logbook prototype was also tailored to assess student perception compared to using supervisory methods using the old logbook. The Rapid Application Development (RAD) methodology was used in software development while a set of questionnaires was distributed to 65 respondents to obtain their assessment feedback data. The findings show that students have a positive assessment of their perception of the use of this prototype.

    The world has suffered from a critical shortage of Personal Protective Equipment (PPE) (Riva et al., 2007) during the pandemic of Covid-19 for medical staffs, the front liners. Like the whole world, Malaysia also imposed the stay-at-home and Movement Control Order (MCO) to break the chain of infections and flatten the curve of cases. The supply of PPE became a challenge during the lock down. There have been joined efforts from various parties stepping up, with different ways to help the production process of these key equipment but mostly focus on PPTs for male. Another challenge was face mask for Muslim lady health workers who wear hijab. This paper is about how to overcome these challenges and designed a novel face mask clip for hijab, using 3D printing. The face mask clip is for wearing a mask over hijab and is designed by generating a 3D digital file using computer-aided design (Hourcade, Bullock-Rest, & Hansen, 2012) software. Then the 3D design was converted to Standard Tessellation Language (STL) format, for the use of 3D printing systems. Then the design was split into layers for precise printing. The clips were tested by the staff in faculty of Cognitive Sciences and Human Development, Universiti Malaysia Sarawak. Feedbacks were collected by an online survey using the modified System Usability Scale. The participants reported that the clips are very comfortable and easy to use.

    Introduction: Recently mobile communication technology had tremendous advances and became the priority for most of the users with some opponent opinions that highlight the accountability and the privacy issues in using these messaging applications. WhatsApp is scored to be the first top used messaging application worldwide that is used in 180 countries by about 1.5 billion population. This research aims to determine the staff reflections regarding the WhatsApp usage for organizational communication. Methods: This study is implied among the staff at the medical and health life science cluster, Management and Science University (MSU), Malaysia. A questionnaire was distributed to all the staff through an online google form. Responses were analysed by the ‘Statistical Package for Social Sciences’ (SPSS) Version 24.0. Results: Results showed that all the staff responded (100%) are using WhatsApp for organizational communication with variable degrees of satisfaction; 8.1% are extremely satisfied, 61.3 % are satisfied, 12.9% are not satisfied and 16.1 % are extremely not satisfied. Their level of satisfaction is significantly affected by the respondent’s age, benefit of usage, and the time of messaging. Conclusion: To ensure effectiveness of communication through WhatsApp, it should be through official groups and the organization should put specific announced rules for the time of usage and the content of messages to be posted to all members.

    Kalantari K, Afifi AM, Jahangirian H, Webster TJ
    Carbohydr Polym, 2019 Mar 01;207:588-600.
    PMID: 30600043 DOI: 10.1016/j.carbpol.2018.12.011
    This review outlines new developments in the biomedical applications of environmentally friendly ('green') chitosan and chitosan-blend electrospun nanofibers. In recent years, research in functionalized nanofibers has contributed to the development of new drug delivery systems and improved scaffolds for regenerative medicine, which is currently one of the most rapidly growing fields in all of the life sciences. Chitosan is a biopolymer with non-toxic, antibacterial, biodegradable and biocompatible properties. Due to these properties, they are widely applied for biomedical applications such as drug delivery, tissue engineering scaffolds, wound dressings, and antibacterial coatings. Electrospinning is a novel technique for chitosan nanofiber fabrication. These nanofibers can be used in unique applications in biomedical fields due to their high surface area and porosity. The present work reviews recent reports on the biomedical applications of chitosan-based nanofibers in detail.

    The number of small and medium-sized accommodations (SMSAs) has increased in Malaysia in tandem with the growth of the tourism industry worldwide. The states involved in this study were Terengganu, Kelantan and Pahang. The SMSAs in these states are rated using Orchid rating, namely 1-Orchid, 2-Orchid and 3-Orchid, generated by the Ministry of Tourism, Arts and Culture Malaysia (MOTAC). This study applied the Resource-based View (RBV) theory to investigate four factors (marketing management, human resourcesmanagement, innovation capability management and information technology) assumed to be competitive capabilities that may influence accommodation’s performance. The objective of the study is to examine whether the four factors influence the performance of Orchid-rated accommodations located in the East Coast of West Malaysia. The results revealed that the four factors do not have any relationship with the accommodation’s performance. The analysis also singled out one argument of the director of SMSA that competitive capabilities are not important to their business. This argument coincides with the results of the analysis that the four factors are not significant with regards to the accommodations’ performance.

    Mechanism diagrams exhibit visually the organized parts and operations of a biological mechanism. A mechanism diagram can facilitate mechanistic research by providing a mechanistic explanation of the phenomenon of interest. Much research has been focusing on the mechanistic explanation and the explanatory mechanistic models. As a specific type of scientific diagram, a simple mechanism diagram can be explanatory by drawing on the rich explanatory resources of non-depicted background knowledge. The relationship between the visually depicted and the background knowledge is underexplored. It is unclear how the non-depicted background knowledge of a mechanism diagram contributes to providing a better-informed explanation of the phenomenon of interest in biological sciences. With the aim to explore this relationship, I articulate that a mechanism diagram provides a mechanistic explanation by a process called abstraction-by-aggregation. Through visual cues, the unified relevant background knowledge provides an epistemic access to a better-informed explanation.
