The group’s latest strategy emphasizes consultation, lacks spending pledges

Filter-feeding flying reptile was likely devoured by a dinosaur during the early Cretaceous

Arachnids build large lookalikes to ward off predators

The development of effective interventions for neurodegenerative disorders, such as posterior cortical atrophy (a visual Alzheimer's variant), remains to be a significant clinical challenge. We introduce a computational framework using convolutional neural networks (CNNs) as in silico models to simulate visual system degeneration and evaluate intervention strategies. By modeling controlled synaptic decay and comparing three distinct retraining approaches, random data (control), accuracy-based,...
