Vectorized isosurface mapping is critical for conducting scientific research in computational fluid dynamics (CFD). We provide a Python-based tool for the vectorized isosurface mapping of scalar field information in CFD simulation results, with the goal of reducing file size while ensuring file editability and graphical presentation independent of resolution. The ideal interpolation angle is first determined by spatially rotating the target region, which reduces the invalid interpolation range. Second, because it uses the spatial clipping approach, it offers a graphics processing method for particular geometric structures such as 'islands' or 'masks.' Finally, the data size is decreased using Probuf's space-compressed storage format. The application case, which visualizes the spatiotemporal evolution of the EFDC concentration field, demonstrates that the spatial rotation and clipping strategies improve both the spatial interpolation and isosurface tracking effectiveness, and make the analysis results conform better to the actual situation. The spatial compression strategy substantially promotes network propagation and the retrieval of contour maps, supporting multi-scenario analysis web applications based on the isosurface spatiotemporal evolution animation method. © 2022, The Authors.

The biggest bottleneck for nanozymes-initiated chemodynamic therapy (CDT) of cancer is that nanozymes cannot continuously yield hydroxyl radicals towards lasting CDT, given their diffusion and clearance from tumor tissues as well as lower tumor accumulation. Herein, based on a composition-transformable bovine serum albumin (BSA) modified Cu/CuFe2O4 (CCFOB) nanozyme, we present a novel avenue to achieve lasting CDT. This CCFOB nanozyme with peroxidase (POD)-like activity and glutathione depletion ability not only amplifies oxidative stress for effective CDT, but exhibits magnetic targeting and imaging-guided simultaneous photothermal therapy (PTT)/magnetic hyperthermia therapy (MHT)/chemotherapy. Contrasting with traditional cognition, we clarify Cu/CuFe2O4 is actually composed of CuFe2O4 nanocrystal clusters and Cu nanospheres. Attractively, for the first time, it is demonstrated that in residual tumor microenvironment, CCFOB nanozyme could be progressively transformed into BSA modified Cu2O/Cu/CuFe2O4, which renders Cu element in CCFOB to be a Cu+ reservoir to continuingly produce high-reactivity Cu+, thereby granting CCFOB nanozyme increasingly enhanced POD-like activity for lasting CDT despite its diffusion and clearance from tumor tissues. Thus, a programmed synergistic therapy strategy starting with high-intensity PTT/MHT/chemotherapy/CDT to eradicate larger tumors, followed by lasting CDT to eliminate residual tumors and prevent tumor recurrence, has been put forward to eventually realize the concept of "one injection, long-lasting and complete cancer therapy". This strategy may provide a new insight for the design of other high-activity nanozymes. © 2024, The Authors. All rights reserved.

The Yangtze River Delta (YRD) suffers severe surface ozone (O 3 ) pollution during summer (June-July-August, JJA). Elucidating the role of meteorology and emissions is crucial for effective controls on O 3 pollution. We used the Weather Research and Forecasting (WRF) - Community Multiscale Air Quality (CMAQ) modeling system to quantify the influences of meteorology, anthropogenic and biogenic emissions on O 3 variations in the YRD between 2019 and 2022. Contrasting trends in surface O 3 were found in the Hangzhou Bay (HZB) (3.3 μg m −3 yr −1 ) and the rest of the YRD (−1.9 μg m −3 yr −1 ). Underlying factors affecting surface O 3 differed between these two subregions. In HZB, meteorological variations dominated the strong O 3 increase with a contribution of ∼94 %. By contrast, in the rest of the YRD, meteorology (42 %) and anthropogenic emissions (53 %) were both key contributors to the modest O 3 decrease. Our results reveal a shift in O 3 drivers in contrast to 2013–2019, characterized by an increasing importance of meteorology and a decreasing contribution of anthropogenic emissions. Consequently, the anthropogenically driven O 3 decrease, which ensues from current pollutant control policies, is difficult to offset the strong positive meteorological influence such as in HZB. There is an urgent need for stricter and more efficient control of O 3 precursor emissions to mitigate the substantial influences of meteorology. Emissions of non-methane volatile organic compounds are of particular concern, as they are still on the rise.

气候变化背景下,高温会影响职业人群的工作效率并造成劳动生产力损失.本研究基于区域气候模式并采用本土化的暴露-反应函数,预估了未来气候变化情景下中国因高温造成的劳动时间损失.研究发现,与基线期的213亿小时高温相关劳动时间损失相比,到21世纪末在RCP2.6、RCP4.5和RCP8.5情景下,损失将分别增加-17.8%、10.8%及121.1%.损失主要集中在华南、华中和华东地区,其中广东与河南将占到全国总损失的四分之一.因为这些区域的温度将更高、人口更密集、户外工作者在总人群中的比例较大.与RCP2.6、RCP4.5和RCP8.5情景相比,若能实现1.5℃温控目标,将分别能够避免11.8%、33.7%和53.9%的劳动时间损失,相当于避免了全中国21世纪中叶的0.1%、0.6%及1.4%的年均GDP损失.本研究显示未来气候变化会给中国造成严重的热相关劳动生产力损失,并强调亟需采取因地制宜的气候减缓及适应策略以保护职业人群健康.本研究对其他与中国相似的发展中国家同样具有重要意义.

Pyrethroid insecticides are among the most consumed insecticides worldwide and pose a serious threat to human health and the environment. In this study, we applied high-throughput organic analysis testing combined with high-volume solid-phase extraction (Hi-throat/Hi-volume SPE) to investigate the occurrence of 11 pyrethroid insecticides in surface water (n=37), tributaries (n=15), and tap water (n=6) in Taihu Lake Basin. Permethrin was 100% detected as the major contributing pyrethroid insecticide. The contributions of different lake areas to pyrethroid insecticides were as follows: southern (S023–S26, mean 2331 ng/L) > eastern (S01–S04 and S32–S37, mean 1664 ng/L) > western (S17–S22 and S28–S31, mean 1459 ng/L) > northern (S05–S16, mean 821.1 ng/L). The results of the principal component analysis (PCA) with multiple linear regression indicated that the main sources of pyrethroid insecticides in the surface waters of Taihu Lake were landscape maintenance, agricultural cultivation, and livestock breeding. Runoff input plays an important role in the accumulation of pyrethroid insecticides in Taihu Lake, and surrounding rivers contribute 2,292 kg of pyrethroid insecticides to Taihu Lake annually. The results of the risk assessment indicate that pyrethroid insecticides pose a high risk to the ecological environment of Taihu Lake and surrounding humans and need to be taken seriously, and the use of pyrethroid insecticides in the Yangtze River Delta region needs to be controlled. This is the first study in China to report the residue levels in water sources and tap water. © 2022, The Authors. All rights reserved.

In this study, we applied high-volume solid phase extraction (Hi-volume SPE) to investigate the occurrence of 11 pyrethroid insecticides in surface waters of Lake Taihu and its runoff. Permethrin was the most important pollutants, accounting for more than 60% of the total pyrethroid insecticides. The results explained by principal component analysis-multiple linear regression indicated that pyrethroid insecticides in surface waters of Lake Taihu were influenced by human activities such as agriculture and household use. Tributaries play an important role in the distribution of pyrethroid insecticides in Lake Taihu, and the effect of atmospheric deposition can be neglected. The rivers surrounding Lake Taihu contribute 2292 kg of pyrethroid insecticides into Lake Taihu annually. The results of risk assessment indicate that pyrethroid insecticides take high risk to the ecology of Lake Taihu and human beings around it, which needs to be taken seriously and the use of permethrin in the Yangtze River Delta region in particular needs to be controlled. © 2022, The Authors.
