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…

In a preregistered study across four schools (n = 268), we test whether cross-age peer tutoring reduces self-reported mathematics anxiety. We find a small but robust effect concentrated in students starting in the lowest…

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…

We benchmark a depth-4 variational quantum circuit against classical solvers on constrained portfolio selection with up to 18 assets. On simulator and on trapped-ion hardware the quantum approach matches classical soluti…

We study how attention heads specialise when transformer models under 50M parameters are trained on corpora of fewer than 10 million tokens. Across five low-resource languages we find that induction heads emerge later an…

Forty students deployed 96 open-hardware temperature sensors across a mid-sized city over one summer. We describe the calibration protocol, quantify drift against a reference station, and show the network resolves intra-…
