Additive manufacturing of electrochemical interfaces : simultaneous detection of biomarkers by Ho, Eugene Hong Zhuang, Ambrosi, Adriano, Pumera, Martin

“…A real sample analysis of Vitamin C tablet (500 mg), Vitacimin was conducted using the 3D-printed Au electrode obtaining a variation from claimed concentration of ascorbic acid of only about 0.5%. Therefore, electrodes fabricated by 3D printing would certainly represent a viable alternative to conventional electrodes for efficient electrochemical analysis in the future.…”

Query lower bounds for log-concave sampling by Chewi, Sinho, de Dios Pont, Jaume, Li, Jerry, Lu, Chen, Narayanan, Shyam

“…In this work, we establish the following query lower bounds: (1) sampling from strongly log-concave and log-smooth distributions in dimension ≥ 2 requires Ω(log) queries, which is sharp in any constant dimension, and (2) sampling from Gaussians in dimension (hence also from general log-concave and log-smooth distributions in dimension) requires Ωe(min( √ log,)) queries, which is nearly sharp for the class of Gaussians. …”
