Research on Rural Design of Industrial Towns on the Urban Fringe Based on the Needs of China's National Spatial Planning System
Published: 2024-08-23
Subjects: Environmental Studies
As urbanization continues, villages and industrial townships in peri-urban areas are facing increasingly complex challenges and opportunities. These areas are usually at the crossroads of urban and rural areas, and are rich in resources and potential, but are also accompanied by environmental, economic and social problems. In May 2019, China formally promulgated the Several Opinions of the State [...]
Array-based seismic measurements of OSIRIS-REx's re-entry
Published: 2024-08-23
Subjects: Earth Sciences, Geophysics and Seismology, Physical Sciences and Mathematics, Planetary Sciences
The return home of the OSIRIS-REx spacecraft in September 2023 marked only the fifth time that an artificial object entered the Earth's atmosphere at interplanetary velocities. Although rare, such events serve as valuable analogues for natural meteoroid re-entries; enabling study of hypersonic dynamics, shockwave generation, and acoustic-to-seismic coupling. Here, we report on the signatures [...]
Sanitary inspection characteristics, precipitation, and microbial water quality - A three-country study of rural boreholes in Sub-Saharan Africa
Published: 2024-08-23
Subjects: Civil and Environmental Engineering
Microbial contamination of drinking water contributes to a substantive and preventable burden of enteric disease that disproportionately impacts infants and children. The World Health Organization (WHO) has published guidance on water safety and water quality monitoring, including sanitary inspection (SI) of water systems to detect and manage hazards such as fecal contamination. Sanitary [...]
Natural and human drivers of salinity and major ion composition in United States lakes
Published: 2024-08-23
Subjects: Earth Sciences, Environmental Sciences, Other Physical Sciences and Mathematics
Salinity and major ion composition are important for understanding and predicting lake water quality and responses to global changes. However, little is known about salinity and major ionic composition for populations of lakes at the continental scale, nor the corresponding relationships with natural and human factors operating at multiple spatial scales. To fill these knowledge gaps, we examined [...]
On the link between weather regimes and energy shortfall during winter for 28 European countries
Published: 2024-08-23
Subjects: Atmospheric Sciences
Increasing the proportion of energy generation from renewables is one of the necessary steps towards reducing greenhouse gas emissions. However, renewable energy sources such as wind and solar are highly weather sensitive, leading to a challenge when balancing energy demand and energy production. Identifying periods of high shortfall, here defined as when demand exceeds production by renewables, [...]
The Origin of Forearc Depressions
Published: 2024-08-23
Subjects: Earth Sciences, Geology, Sedimentology, Tectonics and Structure
Forearc depressions form over continental subduction zones with young, slowly subducting slabs and thick trench fills. They are bound seaward by a coast range and landward by a volcanic arc such that subsidence in forearc depressions occurs between orogens and in areas characterized by plate convergence. We propose a model for forearc depression formation based on geophysical and seismic data [...]
Complex and confined laboratory ruptures explain scaling of the critical slip distance for earthquake faulting
Published: 2024-08-22
Subjects: Earth Sciences, Geophysics and Seismology, Physical Sciences and Mathematics, Tectonics and Structure
Earthquake sequences in nature are complex, exhibiting a range of magnitudes and slip behaviors. In contrast, earthquake-like instabilities generated on frictional faults in the laboratory and in continuum numerical models are usually quasi-periodic with a smaller range of magnitudes and durations. The discrepancy, especially apparent for cm-sized samples used in lab friction experiments, has [...]
Operationalizing accessibility in environmental sustainability efforts: Challenges, barriers, and opportunities
Published: 2024-08-22
Subjects: Environmental Studies
There is growing recognition of the need to move towards climate justice in response to the climate crisis; that is, ensuring mitigation and adaptation responses centre equity, and promote the inclusion of marginalized or otherwise ‘equity-deserving’ groups, including people with disabilities. Despite this recognition, there is little empirical research exploring the intersection of disability in [...]
End-to-End Deployment of the Educational AI Hub for Personalized Learning and Engagement: A Case Study on Environmental Science Education
Published: 2024-08-22
Subjects: Education, Engineering, Engineering Education
This study introduces an end-to-end framework for deploying artificial intelligence (AI) enabled educational assistants tailored specifically for environmental sciences learning needs in higher education. Leveraging state-of-the-art AI and natural language processing (NLP) technologies, the framework provides personalized learning experiences by facilitating access to complex environmental data [...]
Decision-making under flood predictions: a risk perception study of coastal real estate
Published: 2024-08-22
Subjects: Social and Behavioral Sciences
Flood models, while representing our best knowledge of a natural phenomenon, are continually evolving. Their predictions, albeit undeniably important for flood risk management, contain considerable uncertainties related to model structure, parameterisation, and input data. With multiple sources of flood predictions becoming increasingly available through online flood maps, the uncertainties in [...]
Evolution of the Spatial Pattern of Manufacturing Innovation Capacity and Influencing Factors in the Yangtze River Delta Region
Published: 2024-08-22
Subjects: Higher Education
This paper aims to reveal the temporal and spatial evolution characteristics and influencing factors of manufacturing innovation capacity in the Yangtze River Delta region, providing empirical references for formulating regional manufacturing innovation center layout policies. Using the number of patents granted in the manufacturing industry to represent manufacturing innovation capacity, [...]

Larger and Steadier Warming since 1850 from Harmonized Land and Ocean Temperature Records
Published: 2024-08-22
Subjects: Physical Sciences and Mathematics
Accurate historical temperature estimates are crucial for understanding current warming levels and informing policy decisions. Trends in global land and ocean temperatures diverge, however, before 1945. Inter-calibration of coastal land-ocean temperatures indicates that this divergence arises from under-corrected biases in sea-surface temperature linked to late 19th century instrumentation [...]
MicroCrystalNet: An Efficient Convolutional Neural Network for Microcrystal Classification using Scanning Electron Microscope Petrography
Published: 2024-08-22
Subjects: Artificial Intelligence and Robotics, Engineering, Other Engineering, Other Environmental Sciences
Morphological characterization of microcrystalline rock textures typically relies upon the visual interpretation and manual measurement of scanning electron microscopy (SEM) imagery: a practice fraught with subjectivity, inefficiency, sampling bias, and data loss. We introduce a state-of-the-art computer vision pipeline, built on deep learning architectures, for segmenting and classifying [...]
Dynamical controls on intensity-duration characteristics of heatwaves in an idealised model
Published: 2024-08-22
Subjects: Atmospheric Sciences, Climate
An idealised climate model is used to study the contribution of the atmospheric circulation to the intensity-duration characteristics of heatwaves. Using the observed correlation between near-surface temperature and lower tropospheric dry static energy (DSE), we study the energetics of the lower troposphere during heatwaves in the model. We observe that, remarkably, the intensity-duration [...]
