Fuzzy classification of countries according to their sustainable economic potential: application of the Solow-Swan and Green Solow models.
Published: 2023-10-02
Subjects: International and Area Studies
The pollution and the progressive depletion of resources are global problems that affect all humanity, but their approach is affected by the different sociopolitical and economic conditions present in the different regions. Thus, the objective of this work is to implement and analyze a methodological structure based on the Solow/Green-Solow models that facilitates the identification and [...]
Short-term magma-carbonate interaction: A modelling perspective
Published: 2023-10-17
Subjects: Physical Sciences and Mathematics
The short-term, syn-eruptive interaction of magma with crustal carbonates can largely affect the eruptive style and drive even low-viscosity magmas toward large explosive eruptions. Only a few studies focus on the short-term interaction and the physical processes behind the experimental observations are still poorly understood. In this work, we study for the first time the short-term [...]

The Application of Wavelet Deconvolution for Noise Reduction in Seismic Data
Published: 2023-10-03
Subjects: Physical Sciences and Mathematics
Seismic data plays a crucial role in investigating subsurface geological structures, but it is often contaminated by noise that reduces interpretability. This study investigates the application of wavelet deconvolution for enhancing seismic data quality by attenuating noise. The methodology involves the preprocessing of field data from Wyoming's Teapot Dome, implementation of trace-by-trace [...]
Two-dimensional ideal magnetohydrodynamic waves on a rotating sphere under a non-Malkus field: I. Continuous spectrum and its ray-theoretical interpretation
Published: 2023-10-05
Subjects: Fluid Dynamics
Two-dimensional ideal incompressible magnetohydrodynamic (MHD) linear waves at the surface of a rotating sphere are studied as a model to imitate the outermost layer of the Earth's core or the solar tachocline. This thin conducting layer is permeated by a toroidal magnetic field the magnitude of which depends only on the latitude. The Malkus background field, which is proportional to the sine of [...]
The contemporary stable isotope hydrology of Lake Suigetsu and surrounding catchment (Japan) and its implications for sediment-derived palaeoclimate records
Published: 2023-10-03
Subjects: Fresh Water Studies, Geochemistry, Hydrology, Meteorology
The Lake Suigetsu sediment cores exemplify a high-quality archive of palaeoclimatic change in East Asia during the past 150 ka. Robust interpretation of stable isotope-based proxy reconstructions from the Suigetsu cores can be aided by a greater understanding of the factors affecting the isotope composition of the lake and how it relates to that of precipitation. Here we use extended contemporary [...]
Insights into deglacial East Asian Monsoon seasonality and inter-regional teleconnections from Lake Suigetsu, Japan
Published: 2023-10-04
Subjects: Climate, Geochemistry
The past evolution of the East Asian Monsoon (EAM) was affected by remote climate processes. However, there is uncertainty surrounding these teleconnections and their impact on each seasonal EAM mode during periods of rapid global change. Here we use the unique biannual precipitation patterns of central Japan to reconstruct winter and summer EAM evolution during the last glacial termination [...]
CASH Paradox, ReWASH, Bronze-2-Gold and JEDI AWAKENS: introduction of new concepts to enhance the sustainability of the water-energy nexus
Published: 2023-10-04
Subjects: Education, Engineering, Social and Behavioral Sciences
Amidst the escalating impacts of climate change and extreme weather events, participatory decision-making in water management stands out as a sustainable approach for disaster risk reduction. Hydrological disasters, such as floods and droughts, are increasing globally due to anthropogenic activities, necessitating adaptation in water infrastructure. The OECD projects severe water stress for 2.3 [...]
The importance of anisotropic viscosity in numerical models for olivine textures in shear and subduction deformations
Published: 2023-10-05
Subjects: Earth Sciences, Geophysics and Seismology, Physical Sciences and Mathematics
Olivine lattice preferred orientation (LPO), or texture, forms in relation to deformation mechanisms such as dislocation creep and can be observed in the upper mantle as seismic anisotropy. Olivine is also mechanically anisotropic, meaning that it responds to stresses differently depending on the direction of the stress. Understanding the interplay between anisotropic viscosity (AV) and LPO, and [...]
Poroelastic Properties of Sierra White Granite
Published: 2023-10-19
Subjects: Engineering
In this work, poroelastic properties of Sierra White granite are determined, including elastic moduli, Biot's effective stress coefficient, α, and Skempton’s pore pressure coefficient, B. The Biot’s coefficient of this rock was determined using two different approaches. It is found that overall, the Biot’s coefficient decreases from 0.77 at low effective stress (3~4 MPa) to 0.45~0.55 at high [...]
Novel observations of East Asian Summer Monsoon evolution during Glacial Termination II from Lake Suigetsu, Japan
Published: 2023-10-04
Subjects: Climate, Geochemistry
Glacial terminations offer a unique opportunity to examine how the East Asian Summer Monsoon (EASM) responds to rapid increases in global temperature and accompanying abrupt climatic reorganisation. Reconstructions from contrasting glacial terminations with differently evolving boundary conditions are of particular value to our understanding of deglacial EASM behaviours, e.g., Termination I (from [...]
Digitization of Weather Records of Seungjeongwon Ilgi: A Historical Weather Dynamics Dataset of the Korean Peninsula in 1623-1910
Published: 2023-10-06
Subjects: Climate, Meteorology, Oceanography and Atmospheric Sciences and Meteorology
Historical weather records from Europe indicate that the Earth experienced substantial climate variability, which caused, for instance, the Little Ice Age and the global crisis in the period between the 14th and 19th centuries. However, it is still unclear how global this climate variability was because of the scarce meteorological data availability in other regions including East Asia, [...]

A shift in the Sr isotopic composition of the magmatic source triggering 2019 paroxysmal eruptions at Stromboli Volcano
Published: 2023-10-05
Subjects: Earth Sciences, Geochemistry, Physical Sciences and Mathematics, Volcanology
The persistent volcanic activity of Stromboli Volcano, Aeolian Islands, Italy, is interrupted by paroxysmal eruptions on a decadal interval. In 2019, two strong paroxysms on July 3rd and August 28th, ended a more than a decade long period of regular strombolian activity. During normal strombolian activity the volcano erupts highly porphyritic scoria and lava (HP)20 with a shoshonitic basalt [...]
