Sensitivity analysis of the refinement to the mann-whitney test

Abdul Rahman Othman, Lai CH

Sains Malaysiana, 2014;43:1095-1100.

The aim of researchers when comparing two independent groups is to collect large normally distributed samples unless they lack the resources to access them. In these situations, there are a myriad of non-parametric tests to select, of which the Mann Whitney U test is the most commonly used. In spite of its great advantages of usage, the U test is capable of producing inflated Type I error when applied in situation of heterogeneity or distinct variances. This current study will present a viable alternative called the refined Mann-Whitney test (RMW). A Monte Carlo evaluation test is conducted on RMW using artificial data of various combinations of extreme test conditions. This study reviews that the RMW test justified its development by enhancing the performance of the U test. The RMW test is able to control well its Type I error rates even though it has a lower power.

Abdul Razak SF, Yogarayan S, Azman A, Abdullah MFA, Muhamad Amin AH, Salleh M

F1000Res, 2021;10:1265.
PMID: 36852011 DOI: 10.12688/f1000research.73398.2

Background: V2V (Vehicle-to-Vehicle) is a booming research field with a diverse set of services and applications. Most researchers rely on vehicular simulation tools to model traffic and road conditions and evaluate the performance of network protocols. We conducted a scoping review to consider simulators that have been reported in the literature based on successful implementation of V2V systems, tutorials, documentation, examples, and/or discussion groups. Methods: Simulators that have limited information were not included. The selected simulators are described individually and compared based on their requirements and features, i.e., origin, traffic model, scalability, and traffic features. This scoping review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR). The review considered only research published in English (in journals and conference papers) completed after 2015. Further, three reviewers initiated the data extraction phase to retrieve information from the published papers. Results: Most simulators can simulate system behaviour by modelling the events according to pre-defined scenarios. However, the main challenge faced is integrating the three components to simulate a road environment in either microscopic, macroscopic or mesoscopic models. These components include mobility generators, VANET simulators and network simulators. These simulators require the integration and synchronisation of the transportation domain and the communication domain. Simulation modelling can be run using a different types of simulators that are cost-effective and scalable for evaluating the performance of V2V systems in urban environments. In addition, we also considered the ability of the vehicular simulation tools to support wireless sensors. Conclusions: The outcome of this study may reduce the time required for other researchers to work on other applications involving V2V systems and as a reference for the study and development of new traffic simulators.

Edge computing for Vehicle to Everything: a short review

Abdullah MFA, Yogarayan S, Abdul Razak SF, Azman A, Muhamad Amin AH, Salleh M

F1000Res, 2021;10:1104.
PMID: 38595984 DOI: 10.12688/f1000research.73269.4

Vehicle to Everything (V2X) communications and services have sparked considerable interest as a potential component of future Intelligent Transportation Systems. V2X serves to organise communication and interaction between vehicle to vehicle (V2V), vehicle to infrastructure (V2I), vehicle to pedestrians (V2P), and vehicle to networks (V2N). However, having multiple communication channels can generate a vast amount of data for processing and distribution. In addition, V2X services may be subject to performance requirements relating to dynamic handover and low latency communication channels. Good throughput, lower delay, and reliable packet delivery are the core requirements for V2X services. Edge Computing (EC) may be a feasible option to address the challenge of dynamic handover and low latency to allow V2X information to be transmitted across vehicles. Currently, existing comparative studies do not cover the applicability of EC for V2X. This review explores EC approaches to determine the relevance for V2X communication and services. EC allows devices to carry out part or all of the data processing at the point where data is collected. The emphasis of this review is on several methods identified in the literature for implementing effective EC. We describe each method individually and compare them according to their applicability. The findings of this work indicate that most methods can simulate the EC positioning under predefined scenarios. These include the use of Mobile Edge Computing, Cloudlet, and Fog Computing. However, since most studies are carried out using simulation tools, there is a potential limitation in that crucial data in the search for EC positioning may be overlooked and ignored for bandwidth reduction. The EC approaches considered in this work are limited to the literature on the successful implementation of V2X communication and services. The outcome of this work could considerably help other researchers better characterise EC applicability for V2X communications and services.

Fulltext A rapid and sensitive Loop-mediated isothermal amplification assay for detection of pork DNA based on porcine tRNA lys and ATPase 8 genes

Abdullahi, U.F., Igwenagu, E., Aliyu, S., Mu’azu, A., Naim, R., Wan-Taib, W.R.

International Food Research Journal, 2017;24(4):1357-1361.
MyJurnal

This study describes the development of a rapid and sensitive Loop-mediated isothermal
amplification assay for detection of swine DNA in adulterated meat and meat products. The
need to protect consumer’s right to eat foods of their choices, has made it imperative for
researchers to develop efficient means of screening and certification of food products. Six sets
of LAMP primers designed based on porcine tRNA lysine gene and ATPase subunit 8 genes
were used for the assay. Amplification was carried out under constant temperature (630C), using
a simple laboratory water bath. Average time spent in amplification and detection of results was
25 min. All results were visually detected and confirmed by electrophoresis. Detection limit of
the assay was 0.03 femtogram (fg) much high than the PCR assay, and detection probability of
the assay was 100%. Detection of 0.5% of pork spiked with 99.5% of cattle beef is indicative
of the sensitivity and robustness of the assay. This could serve as a prototype for development
of a sensitive and inexpensive Swine DNA LAMP detection kit.

C-Abl Inhibition; A Novel Therapeutic Target for Parkinson's Disease

Abushouk AI, Negida A, Elshenawy RA, Zein H, Hammad AM, Menshawy A, et al.

CNS Neurol Disord Drug Targets, 2018 Apr 26;17(1):14-21.
PMID: 28571531 DOI: 10.2174/1871527316666170602101538

Parkinson's disease (PD) is the most prevalent movement disorder in the world. The major pathological hallmarks of PD are death of dopaminergic neurons and the formation of Lewy bodies. At the moment, there is no cure for PD; current treatments are symptomatic. Investigators are searching for neuroprotective agents and disease modifying strategies to slow the progress of neurodegeneration. However, due to lack of data about the main pathological sequence of PD, many drug targets failed to provide neuroprotective effects in human trials. Recent evidence suggests the involvement of C-Abelson (c-Abl) tyrosine kinase enzyme in the pathogenesis of PD. Through parkin inactivation, alpha synuclein aggregation, and impaired autophagy of toxic elements. Experimental studies showed that (1) c-Abl activation is involved in neurodegeneration and (2) c-Abl inhibition shows neuroprotective effects and prevents dopaminergic neuronal' death. Current evidence from experimental studies and the first in-human trial shows that c-Abl inhibition holds the promise for neuroprotection against PD and therefore, justifies the movement towards larger clinical trials. In this review article, we discussed the role of c-Abl in PD pathogenesis and the findings of preclinical experiments and the first in-human trial. In addition, based on lessons from the last decade and current preclinical evidence, we provide recommendations for future research in this area.

Achour M, Mohd Nor MR, Amel B, Bin Seman HM, MohdYusoff MYZ

J Relig Health, 2017 Oct;56(5):1870-1889.
PMID: 28160189 DOI: 10.1007/s10943-017-0361-9

This study examines the relationship between religiosity and level of happiness in an Islamic context among Muslim students studying at Malaysian universities. The determinants of happiness included in this research are positive attitudes, self-esteem, and other-esteem. Religiosity has long been considered as the main determinant in increasing happiness, and educational level strengthens its relationship. For this purpose, the researchers sampled 230 Muslim students aged 17-40 years studying at Malaysian universities in Kuala Lumpur, Malaysia. The study found a positive and significant correlation between religious commitment and level of happiness. Religious commitment also shows positive and significant correlations with positive attitudes, self-esteem, and other-esteem. The study also concludes that educational attainment moderates the relationship between religious commitment and happiness. Thus, religious commitment plays a very important role in increasing levels of happiness.

Ahmad Fazlan Ghazalli, Mahamad Yusof Abdul Rani, Nelfianty Mohd

Jurnal Sains Sukan & Pendidikan Jasmani, 2017;6(1):45-52.
MyJurnal

The purpose of this study examines the effect of Selangor weightlifters concerns over the performance of the National Weightlifting Championship in Johor Bahru 2015. The sample is Selangor weightlifting athletes aged 13 to 15 years who participated in the national weightlifting championship in Johor Bahru. Data were collected through questionnaires Competitive State Anxiety Inventory (CSAI-2) to measure the level of anxiety (cognitive, somatic, self-confidence). The mean value analysis, the percentage used to determine the level of concern for athletes. Correlation tests were used to examine the association between the phases of concern with the performance of athletes during the competition. The results showed the level of anxiety (cognitive, somatic and self-confidence) athletes a day before the tournament is at a moderate level. Other while, cognitive anxiety level significantly correlated with performance or achievement during the tournament. Therefore, the coaches and athletes must continue to concentrate on the concerns of cognitive intentions to achieve excellent performance in a weightlifting tournament in the future. Researchers suggest the management should seek the help of a sports psychologist to provide psychological training for athletes particularly to address the concerns of cognitive as well as physical exercise by periods of sustained exercise.

Ahmad Nadzri SNZ, Hameed Sultan MT, Md Shah AU, Safri SNA, Basri AA

Polymers (Basel), 2020 Jun 04;12(6).
PMID: 32512701 DOI: 10.3390/polym12061285

Environmental awareness and trends to develop sustainable resources have directed much research attention towards kenaf fibre as an alternative reinforcement in composite manufacturing. Numerous studies have been conducted on kenaf and its hybrid composites. Most studies were conducted on kenaf/glass hybrid composites compared to other kenaf/synthetic hybrid composites. Similar with other materials, mechanical properties were the fundamental knowledge identified by the researcher. Limited studies conducted on other properties have restricted the use of kenaf composites to non-structural applications. To extend the potential of kenaf composites to automotive exterior or other critical applications, studies on impact properties can be a valuable contribution in the material field. This review discusses the mechanical and low velocity impact properties of kenaf/glass hybrid composites reported previously. Percentage loading of fibre, the angle of orientation in woven fibres and the chemical treatment applied to the fibre before compounding are the three major parameters that affect the mechanical and impact properties of the composites. This review provides insights into the mechanical and impact properties of kenaf/glass hybrid composites for future research.

Ahmed A, Adam M, Ghafar NA, Muhammad M, Ebrahim NA

Iran J Public Health, 2016 Sep;45(9):1118-1125.
PMID: 27957456

BACKGROUND: Citation metrics and total publications in a field has become the gold standard for rating researchers and viability of a field. Hence, stimulating demand for citation has led to a search for useful strategies to improve performance metric index. Meanwhile, title, abstract and morphologic qualities of the articles attract researchers to scientific publications. Yet, there is relatively little understanding of the citation trend in disability related fields. We aimed to provide an insight into the factors associated with citation increase in this field. Additionally, we tried to know at what page number an article might appear attractive to disability researchers needs. Thus, our focus is placed on the article page count and the number of authors contributing to the fields per article.
METHODS: To this end, we evaluated the quantitative characteristics of top cited articles in the fields with a total citation (≥50) in the Web of Science (WoS) database. Using one-way independent ANOVA, data extracted spanning a period of 1980-2015 were analyzed, while the non-parametric data analysis uses Kruskal-Walis test.
RESULTS: Articles with 11 to 20 pages attract more citations followed by those within the range of zero to 10. Articles with upward 21 pages are the least cited. Surprisingly, articles with more than two authors are significantly (P<0.05) less cited and the citation decreases as the number of authors increased.
CONCLUSION: Collaborative studies enjoy wider utilization and more citation, yet discounted merit of additional pages and limited collaborative research in disability field is revealed in this study.

Akbar John, B., Kamaruzzaman, B.Y., Jalal, K.C.A., Zaleha, K.

International Food Research Journal, 2012;19(2):423-425.
MyJurnal

Endotoxins (chemically known as Lipopolysaccharide) from gram-negative microorganisms initiates clot formation in blood when it is accidentally encountered by horseshoe crab blood stream. This property was extensively studied by various researchers as a result Limulus Amebocyte Lysate (LAL) test was established. The LAL tests in general, 3 to 300 times more sensitive than the United States Pharmacopeial (USP) rabbit pyrogen test method. It is apparent that major differences among the LAL preparations lie in the area of sensitivity. Differences, up to 100-fold, exist in the sensitivity of the various LAL preparations to the same endotoxin. Based on the above perspective, a portable Kit (Endo sensor) was developed to detect the presence of bacterial endotoxin in liquid biological samples using Tachypleus Amebocyte Lysate (TAL) as a source. Sensitivity of the Kit was determined using various concentrations of prepared endotoxin standards and pyrogen free water samples. It was observed that Endo sensor could detect up to nano gram level of endotoxin in liquid biological samples which could be expressed in (EU/ml) and the labeled sensitivity of the lysated product was 0.125 EU/ml. The gel clotting principle method was utilized for the detection of bacterial endotoxin in liquid biological samples.

An in vitro study to evaluate the genotoxicity of value added hydroxyapatite as a bone replacement material

Akram Hassan, Swaminathan D

Sains Malaysiana, 2011;40.

Hydroxyapatite (HA) used for bone replacement is one of the most active areas of ceramic biomaterials research currently. It has been used clinically for the last 20 years due to its excellent biocompatibility, osseoconduction and osseointegration. Many modifications have been done to develop a stronger, tougher and biocompatible ceramic biomaterial because pure HA is brittle. Researchers in Universiti Sains Malaysia had developed this value added HA that is stronger and less brittle compared to pure HA. The objective of this in vitro study was to evaluate the genotoxic characteristic of the value added HA based material by using Bacterial Reverse Mutation Assay (Ames test). The Bacterial Reverse Mutation Assay of HA was performed on Salmonella typhimurium strains TA98, TA100, TA1535, TA1537 and Escherichia coli strain WP2 uvrA using the preincubation method in the presence and absence of an exogenous metabolic activation system. All the bacterial tester strains treated with and without S9 Mix showed no increase of revertant colonies with increase in concentration of test substance for both the dose finding test and the main test. The number of revertant colonies was less than twice that of the solvent control for all the five bacterial strains and this was reproducible for both the dose finding test and the main test. The numbers of revertant colonies in the negative and positive controls were within the background data of our laboratory. In conclusion the results of the tests showed that the value added HA was considered to have no reverse mutagenic potential under the present test conditions.

A resistant variety with high yielding potential is key for increasing crop production to
fulfill the food requirement of the ever increasing world populations. Consequently, the aim of plant
breeders is to develop high yielding varieties or cultivars that are resistant or tolerant to specific
diseases or insects. For developing a resistant variety, it is enormously indispensable to incorporate or
introgress the specific resistant genes of that particular disease into the recipient. Suppression
subtractive hybridization (SSH) is a powerful technique for the identification of disease specific
differentially expressed genes that are expressed in a resistant or susceptible variety. This paper
presents a brief review on the SSH technique with examples focusing on the identification of the
wheat disease specific differentially expressed genes and their defense mechanisms against fungal
pathogens in global wheat cultivars. This review is helpful for wheat researchers for the updated
information on the SSH technique for the identification of differentially expressed genes in the global
wheat cultivars and varieties. Eventually, the identified genes could be used to develop the disease
resistance variety through marker-assisted backcrossing programme or conventional breeding.

The Brain-Derived Neurotrophic Factor (BDNF) gene Val66Met (rs6265) polymorphism and stress among preclinical medical students in Malaysia

Al-Hatamleh MAI, Hussin TMAR, Taib WRW, Ismail I

J Taibah Univ Med Sci, 2019 Oct;14(5):431-438.
PMID: 31728141 DOI: 10.1016/j.jtumed.2019.09.003

Objective: This study aimed to determine the allelic and genotypic association of the Val66Met (rs6265) polymorphism in the BDNF gene with stress levels in preclinical medical students of Universiti Sultan Zainal Abidin (UniSZA), Terengganu, Malaysia.
Methods: In this cross-sectional study, we recruited all 122 preclinical medical students. The validated depression anxiety stress scales-21 (DASS-21) questionnaire was distributed and blood samples were collected from each subject for DNA extraction. Genotyping analysis of the BDNF gene (Val66Met) polymorphism was performed via an optimised polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.
Results: A total of 105 subjects agreed to participate in this study. Indian students were found to more likely have the Val/Val genotype, whereas Malay students were more likely to have the Met/Met genotype (p = 0.027). Individuals carrying any one of the three BDNF genotypes (Val/Val, Val/Met and Met/Met) differed significantly from each other in terms of their perception of stress (p = 0.010); students carrying the Val/Val genotype (M = 10.6) perceived significantly lower stress than students carrying the Val/Met (M = 14) and Met/Met (M = 15.1) genotypes.
Conclusion: In our study, the Met-allele was associated with higher stress levels. To the best of our knowledge, this is the first study investigating this stress-related gene in medical students. The findings from this study should trigger more investigators to focus on the impact of stress on genetically predisposed medical students.

Fulltext The effects of rainfall event and land use characteristics on river basin hydrological response: a case of Sg. Kayu Ara, Malaysia

Alaghmand, S., Abdullah, R., Abustan, I., Vosoogh, B.

Pertanika Journal of Science & Technology, 2012;20(2):205-219.
MyJurnal

As a crucial demand in urban areas, flood risk management has been considered by researchers and decision makers around the world. In this case, hydrological modelling that simulates rainfall-runoff process plays a significant role. This paper quantified the roles of three main parameters in river basin hydrological response, namely, rainfall event duration, rainfall event ARI (magnitude) and land-use development condition. The case study area of this research was Sungai Kayu Ara basin which is located in the western part of Kuala Lumpur, Malaysia. A total of twenty seven scenario were defined for this research, including three different rainfall event durations (60, 120 and 360 minutes), three different ARIs (20, 50 and 100 years) and in three different land-use conditions (existing, intermediate and ultimate). The results of this research indicate that rainfall event duration, rainfall event ARI (magnitude) and land-use development condition have considerable effects of the surface runoff hydrographs in terms of peak discharge and volume.

Sim-to-Real: Employing ultrasonic guided wave digital surrogates and transfer learning for damage visualization

Alguri KS, Chia CC, Harley JB

Ultrasonics, 2021 Mar;111:106338.
PMID: 33338729 DOI: 10.1016/j.ultras.2020.106338

Wavefield imaging is a powerful visualization tool in nondestructive evaluation for studying ultrasonic wave propagation and its interactions with damage. To isolate and study damage scattering, damage-free baseline data is often subtracted from a wavefield. This is often necessary because the damage wavefield can be orders of magnitude weaker than the incident waves. Yet, baselines are not always accessible. When the baselines are accessible, the experimental conditions for the baseline and test data must be extremely similar. Researchers have created several baseline-free approaches for isolating damage wavefields, but these often rely on specific experimental setups. In this paper, we discuss a flexible approach based on ultrasonic guided wave digital surrogates (i.e., numerical simulations of incident waves) and transfer learning. We demonstrate this approach with two setups. We first isolate reflections from a circular, 2 mm diameter half-thickness hole on a 10 × 10 cm steel plate. We then isolate 8 circular, half-thickness holes of various diameters from 1 mm to 40 mm on a 60 × 60 cm steel plate. The second plate has a non-square geometry and the data has multi-path reflections. With both data sets, we isolate damage reflections without explicit experimental baselines. We also briefly illustrate the comparison of our dictionary learning method with wavenumber filtering technique which is often used to enhance the defect wavefields.

Fulltext Development of a valid and reliable software customization model for SaaS quality through iterative method: perspectives from academia

Ali AQ, Md Sultan AB, Abd Ghani AA, Zulzalil H

PeerJ Comput Sci, 2020;6:e294.
PMID: 33816945 DOI: 10.7717/peerj-cs.294

Despite the benefits of standardization, the customization of Software as a Service (SaaS) application is also essential because of the many unique requirements of customers. This study, therefore, focuses on the development of a valid and reliable software customization model for SaaS quality that consists of (1) generic software customization types and a list of common practices for each customization type in the SaaS multi-tenant context, and (2) key quality attributes of SaaS applications associated with customization. The study was divided into three phases: the conceptualization of the model, analysis of its validity using SaaS academic-derived expertise, and evaluation of its reliability by submitting it to an internal consistency reliability test conducted by software-engineer researchers. The model was initially devised based on six customization approaches, 46 customization practices, and 13 quality attributes in the SaaS multi-tenant context. Subsequently, its content was validated over two rounds of testing after which one approach and 14 practices were removed and 20 practices were reformulated. The internal consistency reliability study was thereafter conducted by 34 software engineer researchers. All constructs of the content-validated model were found to be reliable in this study. The final version of the model consists of 6 constructs and 44 items. These six constructs and their associated items are as follows: (1) Configuration (eight items), (2) Composition (four items), (3) Extension (six items), 4) Integration (eight items), (5) Modification (five items), and (6) SaaS quality (13 items). The results of the study may contribute to enhancing the capability of empirically analyzing the impact of software customization on SaaS quality by benefiting from all resultant constructs and items.

Fulltext Total quality management in the health-care context: integrating the literature and directing future research

Alzoubi MM, Hayati KS, Rosliza AM, Ahmad AA, Al-Hamdan ZM

Risk Manag Healthc Policy, 2019;12:167-177.
PMID: 31576185 DOI: 10.2147/RMHP.S197038

Background: Synergistic integration of predictors and elements that determine the success of total quality management (TQM) implementations in hospitals has been the bane of theoretical development in the TQM research area. Thus, this paper aims to offer a systematic literature review to provide a foundation on which research on TQM can be built and to identify the predictors of successful TQM in the health-care context.
Materials and methods: A systematic literature survey was adopted in this paper, involving the review of 25 relevant researched articles found in the databases Science Direct, EBSCO, MEDLINE, CINAHL and PubMed.
Result: The systematic literature survey reveals five variables to be core predictors of TQM, signifying how important these variables are in the successful implementation of TQM in the health-care context. Also, it is revealed that the identified core predictors have positive effects on an improved health-care system. However, the systematic survey of the literature reveals a dearth of studies on TQM in the health-care context.
Conclusion: As TQM has become an important management approach for advancing effectiveness in the health-care sector, this kind of research is of value to researchers and managers. Stakeholders in the health sectors should introduce and implement TQM in hospitals and clinics. Nevertheless, this study has limitations, including that the databases and search engines adopted for the literature search are not exhaustive.

Fulltext An Accidental Finding of Pulmonary Sequestration in an Adult

Amran, A.R.

International Medical Journal Malaysia, 2006;5(1):1-6.
MyJurnal

Pulmonary sequestration is defined as a segment of ç separated from the tracheobronchial tree and receiving its blood supply from a systemic artery rather than a pulmonary arterial branch. Classically, it has been described in two forms: (1) intralobar sequestration (ILS), in which the sequestrated part of lung lies within normal pulmonary visceral pleura, and (2) extralobar sequestration (ELS), in which the abnormal segment of lung is completely separate and enclosed in its own pleural investment. The term sequestration was coined by Pryce in 1946 to describe a disconnected bronchopulmonary mass or cyst with an anomalous systemic artery. Since this original description, terminology has become confusing as investigator has recognized many variants of sequestration not strictly meeting the original description. The spectrum now recognized as a continuum, with normal vessels supplying abnormal lung at one end and abnormal vessels supplying normal lung at the other end. Recently, we incidentally found an asymptomatic, intralobar pulmonary sequestration during CT pneumocolon.
