A Semi-Empirical Method for Estimating All-Sky Photosynthetically Active Radiation from Sentinel-2 for High-Resolution Land Surface Analysis

Photosynthetically active radiation (PAR) is a fundamental driver of terrestrial photosynthesis and a key input for light use efficiency-based estimates of gross primary productivity (GPP). However, existing PAR products are typically designed for regional to global applications...

Inventories of Rich Carbon-Chain Chemistry in Prestellar and Starless Cores in the Perseus Molecular Cloud

Abstract Carbon-chain molecules serve as an important reservoir of reactive organic matter that will eventually be incorporated into protoplanetary disks, planets, and cometary material. Prestellar and starless cores are composed of cold (~ 10 K) and dense (~ 105 cm−3) clumps of...

A tale of ten cities: data bias in human mobility is pervasive and highly location specific

Abstract Large-scale human mobility datasets play increasingly critical roles in many algorithmic systems, business processes, and policy decisions. Unfortunately, there has been little focus on understanding bias and other fundamental shortcomings of these datasets and how they...

Cold Atmospheric Plasma Disrupts Microbial Wound Bioburden: In Vitro, Porcine MRSA Biofilm, and Clinical Fluorescence Evidence from Bench to Bedside

Background: Biofilm-associated microbial burden is a major barrier to wound healing and is increasingly difficult to control in the era of antimicrobial resistance. This translational study evaluated the antimicrobial performance and tissue compatibility of a commercially availab...

Atomic-precision π-driven peptide hydrogel nanofibers with ordered water channels

Aromatic interactions organize molecules into ordered supramolecular architectures, while peptides form functional soft materials through hydrogen bonding and water-mediated assembly. In peptide-based systems, strong aromatic stacking is typically achieved by terminal capping, wh...
