Shared Generator-Based Serverless Multimodal Federated Learning For Medical Image Analysis, Mohammed Adel Al-Shahe, Ahmed Saihood, Mustafa Asaad Hasan

Mesopotamian Journal of Big Data

Medical image analysis constitutes the foundation of the diagnosis of potential life-threatening conditions such as lung cancer. Nevertheless, AI model construction in this context is hindered by strict privacy regulations (e.g., HIPAA, GDPR), the variability of imaging protocols, and the paucity of large annotated datasets. These barriers constrain centralised machine learning and dampen interdisciplinary research. To overcome such barriers, this paper introduces shared generator-serverless federated learning (SGS-FL), a decentralised multimodal medical imaging framework. By employing a shared generator and multidiscriminator architecture, SGS-FL eliminates centralised dependency via cross-modal synthesis, while the communication burden is reduced by embedding a sharing protocol. By …

Optimized Wavelet Scatter Method For Accurate Classification And Segmentation Of Lung Nodules, Enas Hamood Al-Saadi, Ahmed Nidhal Khdiar, Nidhal K. El Abbadi

Mesopotamian Journal of Big Data

Lung cancer is a significant global health concern due to its high mortality rate. This is primarily due to the difficulty of identifying malignant growths in early-stage computed tomography (CT) images. The thing is, it's often hard to tell the difference between a benign nodule and a malignant one. This makes it tricky to figure out what's going on with the patient. That's where these computer-aided diagnosis (CAD) approaches come in. This study introduces a lightweight and interpretable framework for comprehensively analyzing lung nodules, including their detection, classification, and segmentation. This approach uses the wavelet scattering transform (WST) to extract …

Resilience Among Undergraduate First-Year Students: The Differential Effects Of Gender, And Socioeconomic Status, Sahanowas Sk, Santoshi Halder

Journal of Educational and Psychological Studies

Resilience, as a multidimensional psychological construct, may vary with respect to personal characteristics such as gender and social context like socio-economic status, particularly in the Indian context. The researchers aim to explore the effects of gender (male and female) and socioeconomic status (low, moderate & high) on resilience and further investigate whether the effect of gender is independent of different levels of SES. The quantitative survey study included 490 first-year undergraduates (M = 18.97, SD = .83) from three districts of West Bengal. The questionnaire comprised socio-demographic data and the adapted Bengali version of the Connor-Davidson Resilience Scale (CD-RISC). The …

Color Stability Of Conventional, 3d-Printed, And Milled Denture Teeth After Immersion In Coloring Agents: An In Vitro Study, Dany Nassif, Nancy Chemaly, Rim Bourgi, Carole Abi-Ghosn, Louis Hardan, Jihad Fakhouri

International Arab Journal of Dentistry

Objectives: This study investigates the color stability of denture teeth made from different materials when subjected to various staining solutions.

Methods: Forty-five A1 shade upper central incisors were divided into three groups: prefabricated, 3D printed, and milled denture teeth (N=45). Each group was further divided into three subgroups, with teeth immersed in coffee, wine, and artificial saliva for up to 120 days (n=5). ∆E values for color change were measured using an Optishade colorimeter.

Results: The type of teeth, type of solution, and immersion time had a significant effect on color stability (p < 0.001). Interactions between the three variables were all significant (p < 0.001). Conventional denture teeth showed slight color changes with saliva (ΔE = 1.256 by day 120), moderate changes with wine (ΔE = 2.893), and more significant changes with coffee (ΔE = 5.208). Milled denture teeth exhibited no color changes with saliva, noticeable changes with wine (ΔE = 5.359), and moderate changes with coffee (ΔE = 3.137). 3D printed denture teeth showed no color changes with saliva, but increased changes with wine (ΔE = 2.533) and highly significant changes with coffee (ΔE = 10.546). Coffee consistently caused the highest ΔE values, especially in 3D printed teeth.

Conclusions: The study …

Faculty Research, Scholarly, and Creative Activity

Tai Chi practice has been widely adopted to improve balance and prevent falls in older adults. However, the neural mechanisms underlying the benefits of Tai Chi are difficult to evaluate during traditional balance assessments. The goal of this study was to evaluate the effects of Tai Chi and healthy aging on corticomuscular coherence (CMC) while standing in virtual balance-demanding environments. We recorded neural, muscular, and behavioral data in an immersive virtual reality environment while implementing sensory and mechanical perturbations to introduce high postural threats. Through the acquisition of electroencephalography and electromyography signals, we examined β and γ CMC changes in …

Circulating Medium- And Long-Chain Acylcarnitines Are Associated With Plasma P-Tau181 In Cognitively Normal Older Adults, Tahmida Sharmin, Pratishtha Chatterjee, James D. Doecke, Nicholas J. Ashton, Kevin Huynh, Steve Pedrini, Hamid R. Sohrabi, Benjamin Heng, Shaun Eslick, Henrik Zetterberg, Kaj Blennow, Manohar Garg, Ralph N. Martins

Research outputs 2022 to 2026

Alzheimer's disease (AD) pathogenesis involves dysregulation in diverse biochemical processes. Nevertheless, plasma tau phosphorylated at threonine 181 (P-tau181), a recognised AD biomarker, has been described to reflect early-stage cortical amyloid-β (Aβ) deposition in cognitively normal (CN) adults. Therefore, identifying changes in plasma metabolites associated with plasma P-tau181 at the pre-clinical stage may provide insights into underlying biochemical mechanisms to better understand initial AD pathogenesis. In the current study, plasma P-tau181, quantified via single molecule array (Simoa) technology, and plasma metabolites, quantified via targeted-mass spectrometry, were investigated for associations in CN older adults and upon stratification by positron emission tomography (PET)-Aβ …

A Review Of The Summer Treatment Program (Stp) For Youth With Callous-Unemotional (Cu) Traits: Moving Past The “Untreatable” Hypothesis, Daniel A. Waschbusch, Pevitr S. Bansal, Michael T. Willoughby

Department of Psychology Faculty Scholarship and Creative Works

Youth with both callous-unemotional (CU) traits and conduct problems (CP) present a significant challenge for treatment due to their disruptive and aggressive behaviors. While traditional interventions often show significant but insufficiently positive effects, the Summer Treatment Program (STP), an intensive behavior therapy program, has shown promise in addressing these challenges. This review examines the existing research on the STP’s effectiveness for youth with CP and CU (CPCU), highlighting its potential to improve behavioral outcomes and treatment response. However, limitations such as small sample sizes, lack of long-term follow-up, and potential iatrogenic effects are also acknowledged. The review then proposes several …

Disentangling The Association Between Cognitive Flexibility And Anxiety In Autistic Youth: Real-World Flexibility Versus Performance-Based Task Switching, Farah Mahmud, Erin Kang, Rachel G. Mcdonald, Drew Wallace, Carrie Masia Warner

Department of Psychology Faculty Scholarship and Creative Works

Introduction: Anxiety symptoms are highly prevalent among autistic youth yet remain under-recognized and undertreated, in part, due to a limited conceptual understanding of autistic cognition. Emerging evidence suggests that autistic differences in cognitive flexibility (CF) may be associated with a greater likelihood of developing and maintaining anxiety symptoms, relative to non-autistic youth. However, further work is needed to elucidate mechanisms of anxiety vulnerability that could inform potential targets for anxiety treatment in autistic youth. The current study aims to examine the associations between CF and anxiety in this population. Given the complexity of CF as a multifaceted construct, we used …
