Correlation between the golden ratio and nanowire transistor performance
An observation was made in this research regarding the fact that the signatures of isotropic charge distributions in silicon nanowire transistors (NWT) displayed identical characteristics to the golden ratio (Phi). In turn, a simulation was conducted regarding ultra-scaled n-type Si (NWT) with respect to the 5-nm complementary metal-oxide-semiconductor (CMOS) application. The results reveal that the amount of mobile charge in the channel and intrinsic speed of the device are determined by the device geometry and could also be correlated to the golden ratio (Phi). This paper highlights the issue that the optimization of NWT geometry could reduce the impact of the main sources of statistical variability on the Figure of Merit (FoM) of devices. In the context of industrial early successes in fabricating vertically stacked NWT, ensemble Monte Carlo (MC) simulations with quantum correction are used to accurately predict the drive current. This occurs alongside a consideration of the degree to which the carrier transport in the vertically stacked lateral NWTs are complex

Position-Dependent Performance in 5 nm Vertically Stacked Lateral Si Nanowires Transistors
In this work, we investigated the performance of vertically stacked lateral nanowires transistors (NWTs) considering the effects of series resistance. Also, we consider the vertical positions of the lateral nanowires in the stack and diameter variation of the lateral NWTs as new sources of process variability
Does a Nanowire Transistor Follow the Golden Ratio? A 2D Poisson-Schrödinger/3D Monte Carlo Simulation Study
In this work, we observed the signatures of isotropic charge distributions showing the same attributes as the golden ratio (Phi) described in art and architecture, we also present a simulation study of ultra-scaled n-type silicon nanowire transistors (NWT) for the 5nm CMOS application. Our results reveal that the amount of mobile charge in the channel is determined by the device geometry and could also be related to the golden ratio (Phi). We also established a link between the main device characteristics, such as a drive and leakage current, and cross-sectional shape and dimensions of the device. We discussed the correlation between the main Figure of Merit (FoM) and the device variability and reliability
Development Of A Thermostabilized Multiplex PCR Assay For The Rapid Detection Of Methicillin-Resistant Staphylococcus Aureus
Staphylococcus aureus rintang methicillin (MRSA) bertanggungjawab terhadap
kebanyakan jangkitan nosokomial dan komuniti. Ujian kultur konvensional
mengambil masa selama dua hingga lima hari untuk menghasilkan maklumat penuh
mengenai organisma dan pola kerintangan antibiotiknya. Oleh itu, kajian ini bertujuan
untuk membangunkan ujian reaksi berantai polimerasi berganda untuk pengesanan
MRSA dengan pantas. Ujian ini akan mengesan lima gen iaitu 16S rRNA gen dari
genus Staphylococcus,femA Staphylococcus aureus, mecA yang mengekod rintangan
methicillin, lukS yang mengekod pengeluaran leukosidin Panton-Valentine (PVL),
sitotoksin nekrosis, dan satu gen kawalan dalaman secara serentak. Pasangan primer

reaksi berantai polimerasi pada julat 151 hingga 759 bp. Primer yang spesifik
disahkan berdasarkan urutan jujukan DNA produk reaksi berantai polimerasi berganda

The emergence of methicillin-resistant Staphylococcus aureus (MRSA) is
responsible for nosocomial and community-acquired infections. The conventional
culture test takes 2-5 days to yield complete information of the organism and its
antibiotic sensitivity pattern. Hence our present study was focused on developing a
multiplex PCR assay for the rapid detection of MRSA. The assay simultaneously
detected five genes, namely 16S rRNA of the Staphylococcus genus,femA of S. aureus,
mecA that encodes methicillin resistance, lukS that encodes production of Panton-
Valentine leukocidin (PVL), a necrotizing cytotoxin and one internal control. Unique
and specific primer pairs were designed to amplify the 5 genes with the PCR products
ranging from 151 to 759 bp. The specificity of the primers was confirmed by DNA sequencing of the multiplex PCR products and BLAST analysis

Simulation study of vertically stacked lateral Si nanowires transistors for 5 nm CMOS applications
In this paper we present a simulation study of vertically stacked lateral nanowires transistors (NWTs), which may have applications at 5nm CMOS technology. Our simulation approach is based on a collection of simulation techniques to capture the complexity in such ultra-scaled devices. Initially, we used drift-diffusion methodology with activated Poisson-Schrodinger quantum corrections to accurately capture the quantum confinement in the cross-section of the device. Ensemble Monte Carlo simulations are used to accurately evaluate the drive current capturing the complexity of the carrier transport in the NWTs. We compared the current flow in single, double, and triple vertically stacked lateral NWTs with and without contact resistance. The results presented here suggest a consistent link between channel strain and device performance. Furthermore, we propose a device structure for the 5nm CMOS technology node that meets the required industry scaling projection. We also consider the interplay between various sources of statistical variability and reliability in this work
The Role of Kindergarten Teachers in Using the Computer in the Educational Process (Field Study on Schools in the Capital, Amman)
This study sought to know the role of kindergarten teachers in using the computer in the educational process, where the study community of all kindergarten schools are teachers in the capital Amman, and a questionnaire consisting of (10) items was relied upon and a random sample of 75 teachers was chosen in the schools of the capital, Amman. Data were extracted, results were monitored, tabulated, and entered into the computer, and statistical analyzes were performed using the (Statistical Package for Social Sciences) (SPSS). The T-test was used to test the hypothesis of the study. And to verify the stability of the distributed questionnaires, the internal consistency factor (Cronbach's alpha) was calculated, reaching (0.81), which is a value that can be considered acceptable for the purposes of the study. The study resulted in the following: There is a statistically significant relationship at the level of significance 05.0 between kindergarten teachers and the use of the computer in the educational process due to personal factors (age, educational qualification, years of experience). The most important recommendations reached by the study: Holding training courses for teachers on the use of computers in the educational process, and educational institutions should make the computer subject a basic material for all disciplines to enable the teacher and the student to use it with high efficiency in the field of teaching and education and at all educational levels and to find educational computer programs to serve the educational process.

A Review of Graduate Attributes in the Oman Authority for Academic Accreditation and Quality Assurance of Education (OAAAQAE’s) Quality Audit Reports
With the growing importance of the development of graduate attributes (GAs) in higher education, higher education institutions (HEIs) are emphasizing which GAs their graduates attain as part of their mission, vision, and core values, and are required to describe and document how their programs contribute to the development and promotion of those attributes. Qualitative data were collected from 12 quality audit reports from the Oman Authority for Academic Accreditation and Quality Assurance of Education (OAAAQA). This paper identifies the OAAAQA’s key areas of interest and their importance in ensuring quality in college-preparedness programs, as well as making recommendations for future audits. The paper seeks to: (1) highlight the most salient issues that have been raised in their reports regarding GAs and (2) make some suggestions so that HEIs in Oman can establish and implement GAs more effectively to meet both the OAAAQA’s expectations and good international practices. Following a data-driven systematic qualitative content analysis (QCA) of the QA reports, four main categories emerged regarding the GAs. Student learning objectives should be aligned with GA development, while stakeholders’ awareness of these attributes should be raised. Additionally, there is a need for an appropriate evaluation mechanism for GAs to be conducted in a systematic and timely manner. Moreover, GAs should be explicitly assessed and benchmarked based on the feedback obtained from relevant stakeholders. Finally, both internal and external stakeholders should be involved in the GA development and review process
