KACST Arabic Text Classification Project: Overview and Preliminary Results

Electronically formatted Arabic free-texts can be found in abundance these days on the World Wide Web, often linked to commercial enterprises and/or government organizations. Vast tracts of knowledge and relations lie hidden within these texts, knowledge that can be exploited once the correct intelligent tools have been identified and applied. For example, text mining may help with text classification and categorization. Text classification aims to automatically assign text to a predefined category based on identifiable linguistic features. Such a process has different useful applications including, but not restricted to, E-Mail spam detection, web pages content filtering, and automatic message routing. In this paper an overview of King Abdulaziz City for Science and Technology (KACST) Arabic Text Classification Project will be illustrated along with some preliminary results. This project will contribute to the better understanding and elaboration of Arabic text classification techniques

An adaptive moving mesh method for two-dimensional thin film flow equations with surface tension

In this paper, we extend our previous work [A. Alharbi and S. Naire, An adaptive moving mesh method for thin film flow equations with surface tension, J. Computational and Applied Mathematics, 319 (2017), pp. 365-384.] on a one-dimensional r-adaptive moving mesh technique based on a mesh density function and moving mesh partial differential equations (MMPDEs) to two dimensions. As a test problem, we consider the gravitydriven thin film flow down an inclined and pre-wetted plane including surface tension and a moving contact line. This technique accurately captures and resolves the moving contact line and associated fingering instability. Moreover, the computational effort is hugely reduced in comparison to a fixed uniform mesh

Backbending phenomena in light nuclei at A~60 mass region

Recent studies of the backbending phenomenon in medium light weight nuclei near A~60 expanded greatly our interest about how the single particle orbits are nonlinearly affected by the collective motion. As a consequence we have applied a modi…ed version of the exponential model with the inclusion of paring correlation to describe the energy spectra of the ground state bands and/or the backbending phenomenon in mass region at A~60. A firm conclusion is obtained concerning the successful validity of the proposed modified model in describing the backbending phenomenon in this region. Comparison with different theoretical descriptions is discussed.Comment: 4 pages, 1 figure

QED radiative corrections for elastic e(mu)p scattering in hadronic variables

A numerical analysis of QED radiative corrections for elastic e(mu)p cattering in hadronic variables at energies of the current experiment at JLab is performed. The explicit formulas from the review of Akhundov et al. resulting from the integration over the phase space of leptonic variables plus photon are used to obtain the values of the cross sections and the radiative correction factor for unpolarized lepton-proton scattering. Our numerical results agree with the corresponding results arising from the formulas of Afanasev et al.Comment: 4 Pages, 4 figure

Effect of dietary factor on response of the immune system numerically

Systematic Paleontology section that official synonymizes Neognathodus the species pairs of N. medadultimus and N. medexultimus to N. medadultimus, and and N. dilatus and N.metanodosus to N. dilatus. This synonymy is based on our geometric morphometric results that show there is no statistically significant shape difference between the species pairs of N. medadultimus/N. medexultimus and between N. dilatus/N. metanodosus

The Attitudes of Saudi Intermediate Students towards English Speaking Tasks in Flipped Learning via an Online Learning Community

This paper investigates Saudi intermediate students’ attitudes towards using flipped learning via an online learning community to enhance their speaking skill at a Saudi female’s public-school number 186. The writer observed and analysed the effect of using flipped learning in an online community on the development and engagement of students in speaking tasks. The study uses a quantitative quasi-experimental method to describe and analyse the student’s attitudes and development of the speaking skill among Arabic-speaking students in the public-school number 186 in Saudi Arabia during the academic year 2019-2020. The researcher applied a questionnaire and an observation checklist as the main instrument to achieve the study goal. The findings of the study were not statistically significant regarding the effect of flipped learning via an Online Learning Community (OLC) on the development of students’ speaking skill. However, there was a slight difference in the mean scores in favor to the post-test of the experimental group. The students’ attitudes were positive towards the flipped learning via OLC for speaking tasks

Under-triage of older trauma patients in prehospital care: a systematic review

Background: It is argued that many older trauma patients are under-triaged in prehospital care which may adversely affect their outcomes. This systematic review aimed to assess prehospital under-triage rates for older trauma patients, the accuracy of the triage criteria, and the impact of prehospital triage decisions on outcomes. Methods: A computerised literature search using MEDLINE, Scopus, and CINHAL databases was conducted for studies published between 1966 and 2021 using a list of predetermined index terms and their associated alternatives. Studies which met the inclusion criteria were included and critiqued using the Critical Appraisal Skills Programme tool. Due to the heterogeneity of the included studies, narrative synthesis was used in this systematic review. Results: Of the 280 identified studies, 23 met the inclusion criteria. Current trauma triage guidelines have poor sensitivity to identify major trauma and the need for TC care for older adults. Although modified triage tools for this population have improved sensitivity, they showed significantly decreased specificity or were not applied to all older people. The issue of low rates of TC transport for positively triaged older patients is not well understood. Furthermore, the benefits of TC treatment for older patients remain uncertain. Conclusions: This systematic review showed that under-triage is an ongoing issue for older trauma patients in prehospital care and its impact on their outcomes is still uncertain. Further high-quality prospective research is needed to assess the accuracy of prehospital triage criteria, the factors other than the triage criteria that affect transport decisions, and the impact of under-triage on outcomes

Frailty Identification in Prehospital Care: A Scoping Review of the Literature

The proportion of older adults is increasing worldwide. Frailty assessment in prehospital care was suggested to improve triage decisions and paramedics’ judgment. This study aimed to assess the scope and nature of available evidence around frailty identification in prehospital care. A systematic search of the literature was performed using MEDLINE, SCOPUS, CINHAL, and Web of Science to identify relevant articles published from January 2022 downwards. A list of indexed terms and their associated alternatives were pre-determined. Of the 71 identified and reviewed articles after removing duplicates, six articles were included in the review. Due to the heterogeneity of the included articles, the findings were described narratively. The findings of this review showed that the available evidence is limited and heterogenic. Two themes emerged from the findings of the included articles: 1) Paramedics’ Perceptions about Frailty Assessment in Prehospital Care and 2) Frailty Scores for Application in Prehospital Care. Paramedics recognised frailty assessment in pre-hospital care to be feasible and important. They highlighted the need for a simple and clear frailty score that could be used and mentioned to other healthcare professionals when handing over patients. Six frailty scores were reported to be used in prehospital care. The evidence around each frailty score is very limited. Overall, frailty assessment in prehospital care was shown to be important and feasible. Different frailty scores have been assessed for use in prehospital care. Further research investigating frailty identification in prehospital care is needed
