Sparse Recovery Guarantees Under Aggressive Quantisation

D. Abebe (High school)

We extend restricted isometry arguments to the case where measurements are quantised to two bits, and give a recovery bound that degrades gracefully in the quantisation level. Numerical experiments match the predicted sc…

Microplastic Accumulation in Freshwater Gastropods Across an Urban Gradient

N. Haruna (High school), L. Whitfield (Graduate)

We sampled 312 gastropods from nine sites along an urbanisation gradient and quantified microplastic burden by polymer type. Burden scaled with upstream impervious surface area. We discuss limitations of digestion-based…
