Faculty: Information Technology

Abstract: Traditional software effort estimation methods, such as term frequency–inverse document frequency (TF-IDF), are widely used due to their simplicity and interpretability. However, they struggle with limited datasets, fail to capture intricate semantics, and suffer from dimensionality, sparsity, and computational inefficiency. This study used pre-trained word embeddings, including FastText and GPT-2, to improve estimation accuracy in such cases. Seven pre-trained models were evaluated for their ability to effectively represent textual data, addressing the fundamental limitations of TF-IDF through contextualized embeddings. The results show that combining FastText embeddings with support vector machines (SVMs) consistently outperforms traditional approaches, reducing the mean absolute error (MAE) by 5–18% while achieving accuracy comparable to deep learning models like GPT-2. This approach demonstrated the adaptability of pre-trained embeddings for small datasets, balancing semantic richness with computational e

Abstract: This research analyzes some political leaders’ discourse which aims to achieve the objective of persuading their audience to align with their respective viewpoints and policies. Applying the Conceptual Metaphor Theory by Lakoff and Johnson (1980) and guided by the principles of Critical Discourse Analysis by Fairclough (1995), this study examines a corpus of 40 speeches delivered by each of US President Joe Biden and Vice President Kamala Harris. The analysis uncovers a recurrent utilization of metaphors grounded in the domain of life, such as "LIFE IS A BATTLEFIELD," "LIFE IS A JOURNEY," and "LIFE IS A GAME" by Biden. Similarly, Harris frequently employs "LIFE IS A BATTLEFIELD," which conveys attributes of resilience and fortitude, reflecting her capacity as Vice President. Furthermore, the analysis identifies another prevailing conceptual metaphor, "AMERICA IS A PERSON," by Harris. These metaphorical expressions operate as persuasive tools, facilitating the transmission of their respective political ideologies.

Abstract: Autism spectrum disorder (ASD) comprises neurodevelopmental disorders with wide variability in genetic causes and phenotypes, making it challenging to pinpoint causal genes. We performed whole exome sequencing on a modest, ancestrally diverse cohort of 195 families, including 754 individuals (222 with ASD), and identified 38,834 novel private variants. In 68 individuals with ASD (~30%), we identified 92 potentially pathogenic variants in 73 known genes, including BCORL1, CDKL5, CHAMP1, KAT6A, MECP2, and SETD1B. Additionally, we identified 158 potentially pathogenic variants in 120 candidate genes, including DLG3, GABRQ, KALRN, KCTD16, and SLC8A3. We also found 34 copy number variants in 31 individuals overlapping known ASD loci. Our work expands the catalog of ASD genetics by identifying hundreds of variants across diverse ancestral backgrounds, highlighting convergence on nervous system development and signal transduction. These findings provide insights into the genetic underpinnings of ASD and inform molecular diagnosis and potential therapeutic targets.

Abstract: Jambu bol [Syzygium malaccense (L.) Merr. and Perry] is well known to be used in folk medicine and reports are proving the biological activity of each part of this plant. This study aimed to determine the antioxidant activity of S. malaccense L. leaf extract. The methods used in this study were total phenolic content (TPC) assay, 2,2-Diphenyl-1picrylhydrazyl (DPPH) assay, 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS•) radical scavenging activity assay and ferric reducing antioxidant power (FRAP) assay. The results showed that the extract contained TPC of 44.10±0.06 mg GAE/g. The IC50 scavenging activities of DPPH and ABTS• were 0.0334 mg of Ascorbic acid E/g and 0.1352 mg of TE/g, respectively, while the antioxidant reducing power was 1013.50±0.07 mM Fe2+ /g. In conclusion, S. malaccense L. leaf extract was found to possess antioxidant activity, and this extract has potential to be developed to be used in food as a natural antioxidant agent.

Faculty: Allied Medical Sciences

Abstract: Abstract Olive leaf extracts contain several phytochemical and pharmacological properties. This study evaluated the cytotoxic, antioxidant, α amylase inhibitory activities of aqueous, ethanol and ethyl acetate extracts fro m the Nabali, Muhassan and wild olive leaves grown in Jordan. Total polyphenols, flavonoids and flavonols contents, chelating power activity, total antioxidant activity and DPPH free radical scavenging activity of each extract were evaluated. The α amylase inhibitory activity of each extract was evaluated using CNP G3 assay while cytotoxicity was assessed against viability of MCF7 and MB MDA 231 breast cancer cell lines by MTT. The results showed that total polyphenol content was the highest in the ethanoli c wild leaf extract (113.97 mg gallic acid equivalent/g of dry extract). At a concentration of 100 µg/ml, the extracts from ethanolic wild leaf, ethyl acetate of wild leaf, and ethanolic Nabali leaf exhibited the highest chelating activity for ferrous ions (52.4%, 50.5%, and 47.2%). A ll olive leaf extracts significantly reduced MCF7 cell growth, while ethyl acetate wild leaf extract decreased MB MDA 231 viability. The findings revealed a robust correlation between the antioxidant, cytotoxic, and α amylase in hibitory activities of various olive leaf extracts. Further investigations are needed to identify cytoprotective effects of olive leaf extracts and the evaluation of its efficacy in vivo.

Abstract: Background: The purpose of cardiotocograph (CTG) usage is to detect any alterations in fetal heart rate (FHR) early before they are prolonged and profound. However, the use of CTG machines on a routine basis is not an evidence-supported practice. There is no Jordanian study that assesses the midwives’ attitudes toward this machine. This study aimed to identify Jordanian midwives’ attitudes towards the use of cardiotocograph (CTG) machines in labor units, alongside examining the relationships between midwives’ personal sociodemographic characteristics and such attitudes. Methods: A descriptive research design was used to identify Jordanian midwives’ attitudes towards the use of CTG machines in both public and private labor units in Jordan. Data were collected using the valid and reliable tool designed by Sinclair (2001), and these were used to identify midwives’ attitudes towards CTG usage. A total of 329 midwives working in the labor units of governmental and private hospitals in the center and north of Jordan participated in the study from May to July 2022. Results: The total mean score for the attitude scale was M = 3.14 (SD = 0.83). More than half of the sample (N = 187, 58.4 %) demonstrated a mean score greater than 3.14, however, which indicates generally positive attitudes toward CTG usage in labor units. Midwives working in private hospitals and those holding Bachelor’s degrees had more positive attitudes toward the use of CTG machines. Conclusion: This study provides new insights into the attitudes of Jordanian midwives towards CTG use in labor units. These suggest that it is critical to conduct training courses for registered midwives to help them develop and/or regain confidence and competence with respect to various key aspects of intrapartum care, including intermittent auscultation and the appropriate use of CTG.

Abstract: This study determined the cytotoxicity, antioxidant activity, total phenolic and flavonoid contents of hydroethanolic and aqueous extracts of aerial parts of Anchusa strigosa Banks et Sol, Cardaria draba, Marrubium vulgare, Sarcopoterium spinosum and Capparis spinosa. These medicinal plants were collected from Jordan. Hydro-ethanolic and aqueous extracts displayed a strong scavenging capacity for DPPH radical; IC50 values ranging from 11 to 57, and from 13 to 464 g/mL, respectively. Total phenolic contents, expressed as gallic acid equivalent, varied from 3.4 to 16 mg/g dry plant in hydro-ethanolic extract and from 1.8 to 15.1 mg/g in aqueous extracts. Total flavonoids in the same extracts, expressed as quercetin equivalent, ranged from 2.55 to 10.1 and from 0.68 to 9.4 mg/g dry plant, respectively. There was a strong correlation between antioxidant activities and phenolics for aqueous extracts (r= 0.893), but moderate correlation for hydro-ethanolic ones (r=0.581) implying the contribution of other non-phenolic compounds to the antioxidant activity in the latter. Both hydro-ethanolic and aqueous extracts of Sarcopoterium Spinosum showed the highest antioxidant activity, reducing power, phenolic, and flavonoid contents. Therefore, Sarcopoterium Spinosum is a promising candidate for antioxidants from a natural source Furthermore. Hydro-ethanolic extracts of all plants were not toxic to HCT116 or SW480 cell-lines.

Abstract: Abstract: The influence of nonionic surfactant micelles such as Tween 80, polyethylene glycol 400, and coco glucoside on inhibiting aluminum corrosion in hydrobromic acid solutions was investigated via weight reduction, thermometric, and electrical conductivity techniques. In the absence of inhibitors, the rise in temperature and acid levels has led to a tremendous acceleration in aluminum corrosion in HBr solutions. Intriguingly, coco glucoside, PEG 400, and Tween 80 have shown a remarkable inhibitory action on aluminum corrosion in corrosive solutions at different temperatures. The findings demonstrated that the inhibition efficacy of inhibitors and the extent of surface coverage of the micelles on aluminum rise with higher concentrations of the inhibitor and decline with rising temperature. Notably, Tween 80 was a more effective inhibitor than PEG 400, and coco glucoside at all temperatures. This effect may be explained by the force and type of their micelles’ adsorption on the aluminum surface, which occurs when hydrophilic regions of coherent layers of micelles donate their electrons to the metal surface. Also, the thermodynamic factors (ΔH0, ΔS0, and Ea) for the corrosion and adsorption processes were assessed and addressed. The experimental data were best fit by models of Langmuir, Temkin, and Flory–Huggins adsorption isotherms fit each other well.
