Quantum imaging with spatially entangled photons offers advantages such as enhanced spatial resolution, robustness against noise, and counterintuitive phenomena, while a biphoton spatial aberration generally degrades its performance. Biphoton aberration correction has been achieved by using classical beams to detect the aberration source or scanning the correction phase on biphotons if the source is unreachable. Here, a new method named position-correlated biphoton Shack-Hartmann wavefront sensing is introduced, where the phase pattern added on photon pairs with a strong position correlation is reconstructed from their position centroid distribution at the back focal plane of a microlens array.

The glomerular filtration rate (GFR) is a key measure of renal function, typically estimated using creatinine-based equations. More precise clearance measurements are obtained with radiotracers, such as [Tc]Tc-diethylenetriaminepentaacetic acid (DTPA), and blood samples over several hours. However, standard plasma clearance methods require labor-intensive plasma preparation, limiting efficiency in clinical practice.

This study investigates the vertical profiles, pollution status and ecological risks of heavy metal(loid)s contamination in three sediment cores (N21, N03, and 38002) from the North Yellow Sea (NYS), with a focus on the influence of grain size effects on sedimentary profiles. The results revealed distinct vertical distribution patterns of heavy metal(loid)s content among the three sediment cores. Enrichment Factor (EF) and Geo-accumulation Index (I) assessments identified Sb as significantly enriched, indicating anthropogenic influence, whereas Co, Cr, Cu, Ni, and Zn primarily originated from natural weathering.
