How Will Precipitation Characteristics Associated with Tropical Cyclones in Diverse Synoptic Environments Respond to Climate Change?
Published: 2024-06-22
Subjects: Atmospheric Sciences, Climate, Meteorology, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
Landfalling tropical cyclones (TCs) can produce large rainfall totals which lead to devastating flooding, loss of life, and significant damage to infrastructure. Many studies have examined future changes in TC precipitation, however few have considered changes owing to differences in the synoptic environment during landfall. Here we focus on three North Atlantic TCs that impacted the southeastern [...]

Critical transition in barrier islands’ dune ecosystem and the sudden loss of barrier’s resilience
Published: 2024-06-18
Subjects: Physical Sciences and Mathematics
Barrier islands cover a large fraction of US coasts and support unique ecosystems and coastal infrastructure. The 'barrier' function of a barrier island depends on coastal dunes that can prevent storm flooding and widespread ecosystem loss. Furthermore, dune-less barriers are more susceptible to breaching and potential drowning under sea level rise. Here we study the transition from [...]
Modeling the Impact of Storm Surge Flooding and Associated Costs on North Carolina Coastal Region Corn and Soybean Fields via Remote Sensing
Published: 2024-06-16
Subjects: Earth Sciences, Environmental Sciences, Physical Sciences and Mathematics
Hurricane and tropical storm-driven storm surge flooding places coastal farmlands at high risk of crop damage and soil salinization. The damage can total to millions of dollars in costs and force farmers to abandon coastal fields. Additionally, many agricultural, and often rural, areas are unable to access accurate and reliable flood-risk projection maps and analyses that can inform prevention [...]
The Impact Measurement and Application of Conservation System (IMACS): A Review of a Framework for Impact Measurement, Application of Conservation and a Return to Sustainable Conditions
Published: 2024-06-14
Subjects: Physical Sciences and Mathematics
The Impact Measurement and Application of Conservation System (IMACS) was recently described in ten preprint papers. IMACS represents the first “first principals” based system for measurement of damaging and conserving impacts and the calculation of sustainabilities for products, services and individuals. IMACS distinguishes “participating” and [...]
Power optimisation of a rogue-wave energy device in a contraction
Published: 2024-06-14
Subjects: Physical Sciences and Mathematics
We consider optimisation of a wave-energy device placed in a contraction consisting of unidirectional wave-induced buoy motion coupled to a tubular electromagnetic generator. First, optimisation of the generator is achieved by using three induction coils instead of one. Second, geometric optimisation is explored for two contraction-shape parameters. Finally, we discuss the advantages of using [...]
The direction of core soldification in asteroids: implications for dynamo generation.
Published: 2024-06-14
Subjects: Physical Sciences and Mathematics
Paleomagnetic studies of meteorites over the past two decades have revealed that the cores of multiple meteorite parent bodies, including those of certain chondritic groups, generated dynamo fields as they crystallised. However, uncertainties in the direction and mode of core solidification in asteroid-sized bodies have meant using the timings and durations of these fields to constrain parent [...]
The migration of hydrogen in sedimentary basins
Published: 2024-06-13
Subjects: Engineering, Physical Sciences and Mathematics
Understanding the mechanisms of large-scale, subsurface hydrogen migration is essential for natural hydrogen exploration and for hydrogen storage assessment. The unique properties of hydrogen make that the timescales of hydrogen migration within geological basins vary from thousands of years to days. Within the shallow Earth, diffusive and advective transport mechanisms are dependent on a wide [...]
Implementing machine learning to establish a relationship between coal ash spread and lined vs. unlined sites using publicly available data
Published: 2024-06-12
Subjects: Physical Sciences and Mathematics
The fuel combustion process within coal power plants causes a significant amount of waste, called coal ash, often stored in slush basins. Due to low maintenance and lack of proper regulations, coal ash ponds have a high tendency to contaminate nearby groundwater sources. Without a simple way to ascertain whether the drinking water and soil near a private residential area is contaminated, citizens [...]
Providing Conservation as “Title-To-Conservation” Under IMACS
Published: 2024-06-10
Subjects: Physical Sciences and Mathematics
In order to prevent the devastating effects of global warming on biodiversity and in turn on humanity, CO2 emissions and other forms of environmental damage must be all but eliminated, while environmental protection and restoration must be applied on increasingly larger scales. The methods described here are used under the IMAC system and create both the vehicles and the incentives to provide [...]
Calculation of Individual and Product Sustainability under IMACS
Published: 2024-06-10
Subjects: Physical Sciences and Mathematics
The methods described allow calculation of individual and product sustainabilities and of human conditions for all products, services and individual labor, in a globally standardized way. Product and service sustainabilities reflect natural resource use, environmental damage done and harmful or inhumane labor and living conditions that existed, to make, transport and sell the product or service. [...]
Calculation Of Excess Impact Deduction for Products and Services under IMACS
Published: 2024-06-10
Subjects: Physical Sciences and Mathematics
The first universally standardized and first-principal-based system of methods was developed to calculate the environmental (E) and human condition (H) impacts embodied by products and services where EH-impacts originating from employee labor are added to other production process EH-impacts. While the addition of employee labor EH-impacts is essential to correctly calculate the EH-impacts of [...]
Impact Measurement and Application of Conservation System (IMACS)

Subjects: Physical Sciences and Mathematics
This article describes the first “first principals’ based” system of methods for the calculation of environmental (E) and human condition (H) impacts and sustainabilities for all products, services and individuals as a set of universally standardized methods, earlier published as a patent application (1). The overall system allows buyers to select more sustainable products and services, and [...]
Calculation of Individual Sustainable Absorption for IMACS
Published: 2024-06-10
Subjects: Physical Sciences and Mathematics
This article describes the first universally standardized and first-principals-based method to calculate the amounts of environmental and human resources an individual can use sustainably. The sustainable available resource amount calculated for each resource type used, must be deducted from the individual’s resource consumption to calculate the net resource use of the individual’s labor output. [...]
