Background The interpretation of radiographs suffers from an ever-increasing workload in emergency and radiology departments, while missed fractures represent up to 80% diagnostic errors the department. Purpose To assess performance artificial intelligence (AI) system designed aid radiologists physicians detection localization appendicular skeletal fractures. Materials Methods AI was previously trained on 60 170 obtained patients with trauma. were randomly split into 70% training, 10%...

Penicilloneines A (1) and B (2) are the first reported quinolone–citrinin hybrids. They were isolated from starfish-derived fungus Penicillium sp. GGF16-1-2, their structures elucidated using spectroscopic, chemical, computational, single-crystal X-ray diffraction methods. share a common 4-hydroxy-1-methyl-2(1H)-quinolone unit; however, they differ in terms of citrinin moieties, these two units linked via methylene bridge. exhibited antifungal activities against Colletotrichum...

Abstract Background and Aims Soil phosphorus (P) deficiency salinity are constraints to crop productivity in arid semiarid regions. Salinity may weaken the effect of P fertilization on plant growth. We investigated interactive effects soil availability growth, nutrition salt tolerance two alfalfa (Medicago sativa) cultivars. Methods A pot experiment was carried out grow cultivars a loess under combination different rates added (0, 40, 80 160 mg kg−1 as monopotassium phosphate) sodium...

Abstract Surface ozone (O3) is an important secondary pollutant affecting climate change and air quality in the atmosphere. Observations during COVID-19 lockdown urban China show that co-abatement of nitrogen oxides (NOx) volatile organic compounds (VOCs) caused winter ground-level O3 increases, but chemical mechanisms involved are unclear. Here we report field observations Shanghai reveals increasing photochemical formation from VOC oxidation with decreasing NOx. Analyses profiles NO/NO2...

To study the chemical constituents of roots Angelica dahurica, a well-known Chinese herbal medicine named Baizhi in Chinese. Compounds were separated by various chromatographies, and structures new compounds elucidated based on analysis their spectroscopic spectrometric data (1D, 2D NMR, HRESI MS, IR, UV). The absolute configurations determined calculated electronic circular dichroism derivatization. inhibitory activities all isolates against nitric oxide (NO) production evaluated using...

Abstract Zinc‐based batteries are emerging as the most promising candidates for large‐scale energy storage devices due to their low cost, high safety, and long‐term storage. However, zinc‐based encounter challenges stemming from undesirable side reactions zinc dendrites on anode, well dissolution cathode. Owing extremely small size, substantial surface functional groups, adjustable structure, carbon dots (CDs) present considerable benefits in augmenting coulombic efficiency, expanding cycle...

Abstract Aqueous Zn‐ion batteries (AZIBs) are promising energy storage systems due to their low cost, excellent safety, and environmental friendliness. However, challenges like uncontrollable dendrite growth side reactions during battery operation limit commercialization. Addressing these issues requires regulating ion deposition behavior at the anode/electrolyte interface. The electrostatic shielding effect, which leverages interplay between electric potential ionic motion, provides a...
