Organic carbon dry deposition outpaces atmospheric processing with unaccounted implications for air quality and freshwater ecosystems.
Sci Adv

Department of Chemical and Environmental Engineering, Yale University, New Haven, CT, USA.
Dry deposition is an important yet poorly constrained process that removes reactive organic carbon from the atmosphere, making it unavailable for airborne chemical reactions and transferring it to other environmental systems. Using an aircraft-based measurement method, we provide large-scale estimates of total gas-phase organic carbon deposition rates and fluxes. Observed deposition rates downwind of large-scale unconventional oil operations reached up to 100 tC hour, with fluxes exceeding 0.

Introduction: Chronic Kidney Disease (CKD) is a growing global health issue, affecting approximately 9.1% of the world's population. Oxidative stress is believed to play a key role in CKD development, with indicators such as the Oxidative Balance Score (OBS), Pro-Oxidant-Antioxidant Balance (PAB), and Total Antioxidant Capacity (TAC) being of particular interest.

Medical volume data are rapidly increasing, growing from gigabytes to petabytes, which presents significant challenges in organisation, storage, transmission, manipulation, and rendering. To address the challenges, we propose an end-to-end architecture for data compression, leveraging advanced deep learning technologies. This architecture consists of three key modules: downsampling, implicit neural representation (INR), and super-resolution (SR).

Pd-based nanocatalysts hold significant promise for application in alkaline direct ethanol fuel cells (DEFCs). To address the challenges of low Pd atom utilization and poor reaction kinetics in conventional Pd-based catalysts, a self-etching strategy has been developed to synthesize PdPb nanoparticles (NPs) with tunable size and abundant tensile strain. The nanoparticles demonstrated a markedly enhanced electrocatalytic performance.

Division of Spine Surgery, Department of Orthopedic Surgery, Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University, Zhongshan Road 321, Nanjing, 210008, China.
Purpose: This study is to conduct a retrospective review of the selective resection strategies, their immediate efficacy and prognosis, using double hemivertebrae (DHV) as illustrative cases.
Methods: A total of 59 adolescent and young adult patients with DHV were enrolled from 2009 to 2021. They were categorized into sagittal kyphosis group (SKG), coronal takeoff group (CTG) and balanced group (BG).
