Synthesis, characterization, and process optimization of natural coagulants from jackfruit and durian seeds for turbidity removalNARA Subscribed
Starch was extracted from jackfruit and durian seeds using distilled water and alkaline methods, with higher yields obtained via distilled water (27.7% and 18.4%, respectively). The extracted starches were cationized using 3-chloro-2-hydroxypropyltrimethylammonium chloride (CTA) to enhance coagulation performance. Characterization confirmed successful functionalization, with particle size increases of 32% (jackfruit) and 45% (...
Interpretable deep learning reveals spatiotemporal MRI features of brain aging that align with neurodegenerationNARA Subscribed
Cortical thinning and atrophy are hallmarks of brain aging that have been characterized using magnetic resonance imaging (MRI). Brain aging involves many neuroanatomic features whose effects on brain structure remain unexplored. To address this challenge, we trained interpretable deep neural networks (DNNs) to estimate brain age (BA) from T 1 -weighted ( T 1 w) MRI. By identifying MRI features unapparent to humans, DNNs can fi...
From Industrial Residue to Agronomic Asset: Gyplime’s Role in Enhancing Wheat Yield and Soil HealthNARA Subscribed
Gyplime, a by-product of lithium extraction, contains high levels of gypsum (calcium sulfate) and lime (calcium carbonate), making it a potentially valuable amendment. This study examined gyplime’s effect on wheat growth, yield, nutrient uptake, and soil health. A glasshouse experiment was conducted using two soil types: Shenton Park and Kojonup, and four gyplime rates: 0, 2.5, 5.0, and 10 g pot -1 (equivalent to 0, 1, 2, and...
Alzheimer’s disease (AD) disproportionately affects women and carriers of the apolipoprotein E ε4 allele (APOE4), yet little is known about how sex and APOE interact to influence white matter (WM) integrity during disease progression. We integrated diffusion MRI and matched blood transcriptomic data to investigate these interactions and their underlying biological mechanisms. WM microstructure was quantified using diffusion te...
Cortical and deep brain topography are core components of undergraduate neuroanatomy teaching and neurosurgical training. Due to the technical challenges associated with dissecting and maintaining preserved brains, deep white matter preparations are often omitted from anatomy curricula. This reduced opportunity for tactile neuroanatomical exploration contributes to surface-level approaches to learning and is associated with po...
The anthropause as a behavioral reset: persistent reduction in territorial aggression in an urban songbirdNARA Subscribed
Cities are evolutionarily novel environments that can impose unique stressors on wildlife. The period of movement restrictions during the COVID-19 pandemic, dubbed the “anthropause,” temporarily decoupled human activity from urban landscape stressors, creating a natural experiment otherwise impossible to replicate. We investigated whether the post-anthropause increase of human activity affected territorial behavior in urban da...
