Snif: Explainability-Driven Feature Selection Through State-Of-The-Art Shap–Nca Intersection Framework For Malware Detection, Sadia Nazim, Syed Shujaa Hussain, Bilal Yousuf, Jawahir Che Mustapha

Research Outputs: 2025-Present

Modern malware detection rely on Deep neural networks to achieve high detection performance by leveraging a large feature space. However, these models often suffer from high dimensionality, limited interpretability, and reduced reliability due to redundant features. As a result, they obscure the true contribution of features to the rationale for the prediction. To address these challenges, this study proposes an explainability-aware feature pruning technique to improve the performance and efficiency of deep neural networks. The key focus of this study is the development of the novel SHAP–NCA Intersection Framework (SNIF), which integrates explainability with feature selection for efficient and trustworthy …

Impact Of Protein Corona Morphology On Nanoparticle Diffusion In Biological Fluids: Insights From A Mesoscale Approach, Beatrice Cipriani, Hender Lopez

Research Outputs: 2025-Present

Nanoparticles (NPs) demonstrate considerable potential in medical applications, including targeted drug delivery and diagnostic probes. However, their efficacy depends on their ability to navigate through the complex biological environments inside living organisms. In such environments, NPs interact with a dense mixture of biomolecules, which can reduce their mobility and hinder diffusion. Understanding the factors influencing NP diffusion in these environments is key to improving nanomedicine design and predicting toxicological effects. In this study, we propose a computational approach to model NP diffusion in crowded environments. We introduce a mesoscale model that accounts for the combined effects of the protein corona …

Simulation Of Ion Migration In Perovskite Solar Cells At Elevated Temperature And Voltage Levels, Ali Hajjiah, Nima Ghadiri

Research Outputs: 2025-Present

A coupled modeling approach based on Sah-Noyce-Shockley theory has been developed to simulate the ion migration in perovskite solar cells under elevated temperature and bias levels. The model considers the migration of cations (MA⁺) and anions (I⁻) across the structure of a MAPbI₃ solar cell (TiO₂/Perovskite/Spiro) demonstrating how at elevated temperature and applied voltage levels, the ion can migrate with different speed and the ion concentration profiles can influence the device performance parameters. Results reveal that low-energy ions migrate rapidly toward the interfaces under forward or reverse bias, with cation concentrations reaching ∼10 …

Fogt, Louis C. Blumenfeld, Tung M. Fong, Eric Lang, Simon P. Chandler, Houman D. Hemmati

Research Outputs: 2025-Present

Introduction: Stage 2 of the Childhood Atropine for Myopia Progression (CHAMP) study was conducted to observe the safety, efficacy and rebound effects of low-dose atropine sulphate ophthalmic solutions (0.01% and 0.02%) for paediatric myopia in the year following cessation of 3 years of prior treatment. Methods: The study was a multicentre, randomised, double-masked, placebo-controlled Phase 3 clinical trial. Children aged 3 to < 17 years with myopia (spherical equivalent refractive error (SER) from −0.50 to −6.00 D) who entered and completed Stage 1 (3 years of treatment) participated in the fourth-year follow-up (Stage 2). Stage 1 participants who were treated with atropine 0.01% or 0.02% were re-randomised 1:1:1 to atropine 0.01%, atropine 0.02% or vehicle in Stage 2. Stage 1 vehicle-treated participants were re-randomised 1:1 to atropine 0.01% or atropine 0.02% in Stage 2. Outcomes included changes in cycloplegic SER, changes in axial length (AL), responder status continuity and progression to high myopia. Results: Four hundred and twenty participants were randomised in Stage 2. Negligible rebound was observed among the participants who switched from 0.01% atropine to vehicle compared to those who continued on 0.01% atropine treatment (least square mean difference in SER change from Month 36 to Month 48 between continued treatment and switching to vehicle = 0.019 D, 95% CI [−0.14, 0.18], p = 0.82 for the modified Intent to Treat set). Stage 1 responders remained responders in 83-90% of participants in various Stage 2 groups. Safety profiles were favourable, with mild, transient adverse events. Conclusions: Atropine sulphate ophthalmic solution (0.01%) exhibited negligible rebound in myopia progression after treatment cessation following 3 years of continued treatment, highlighting its potential as a treatment option. The treatment maintained a favourable safety record, and the overall benefit and risk assessment support its potential use as a long-term myopia management option. Clinical trial registration: The Childhood Atropine for Myopia Progression (CHAMP) study was registered in clinicaltrials.gov (NCT03350620, registration date November 17, 2017).

Modeling The Impact Of Proton Irradiation On Photoluminescence Spectra Of Perovskite Solar Cells, Ming Lang Tseng, Nima Ghadiri

Research Outputs: 2025-Present

This study presents a comprehensive modeling approach to assess the impact of proton-irradiation on the photoluminescence (PL) response and current–voltage (JV) characteristics of CsMAFAPbI₃/P3HT-based perovskite solar cell validated against experimental data reported in literature. Proton irradiation generates displacement damage across the cell structure most critically within the perovskite bulk where the defect density increases approximately linearly with increased fluence and decreases for high proton energies due to reduced non-ionizing energy loss (NIEL) at higher energies. To capture the optical degradation behavior, Time-Resolved PL transient (TRPL) and PL spectra were modeled using a fluence- and energy-dependent Kohlrausch model (stretched-exponential) …
