Summary: This study investigates the formation of argillic horizons in the Marilia Formation during the Maastrichtian in the Cretaceous period. The study analyzes various soil attributes, including macromorphological and micromorphological data, to understand the polygenetic processes involved. The results suggest that the presence of argillic horizons does not necessarily indicate wet conditions but is associated with changes in granulometry, macroaggregates-microaggregates, carbonate accumulation, and water table oscillation.

Summary: The study of BMS supertranslation generators on a black hole horizon reveals the existence of dual BMS supertranslations and an anomalous central term in the Dirac bracket between these generators. Introduction of a holographic gravitational Chern-Simons theory on the horizon is necessary to remove this central term and preserve general coordinate invariance.

Summary: This paper investigates the thermodynamics of a small body near a black hole horizon using a first-principles analysis. The study focuses on a quantum ideal gas confined in a small box above the Schwarzschild horizon. The authors analyze the system in terms of free quantum fields and identify thermodynamic properties through the microcanonical distribution. They find that the effective dimension of the system changes as it approaches the horizon, and that the pressure is highly anisotropic. Additionally, they show that the approximation of quantum fields on a fixed background breaks down at microscopic distances from the horizon, requiring the inclusion of backreaction effects.

Summary: This letter investigates the effect of a quantum massless scalar field on the Cauchy horizon inside rotating black holes and calculates the impact on the stress-energy tensor. It is found that the effect is generally non-zero and changes sign with varying parameters. Regardless, the results indicate that these effects diverge on the Cauchy horizon.

Summary: The model proposed in this study describes the near-inner horizon geometry of a rotating, accreting black hole using radial streams of a collisionless null fluid. It predicts a Kasner-like collapse towards a spacelike singularity near the inner horizon, interrupting the standard Poisson-Israel mass inflation phenomenon. Through comparison to the conformally separable Kerr model, it is shown to be valid near astrophysically realistic black holes, providing a natural connection to a self-similar, accreting spacetime.

Summary: This paper investigates the orbits of charged particles near the event horizon of a magnetized black hole. By using a properly constructed near-horizon approximation, the properties of these orbits can be effectively and easily determined. It is found that the effective potential can be written in a form invariant under rescaling of the magnetic field, making it universal. The findings have important implications for evaluating the lifetime of particles near black holes.

Summary: This paper investigates the phenomenon of quantum backflow of a quantum particle crossing the event horizon of a Schwarzschild black hole. Through a toy model approach, the study demonstrates a nonvanishing quantum backflow in a small region around the event horizon, contrasting with the classical black hole theory of excitation being lost forever once crossing the horizon. Further implications of this phenomenon are speculated, along with a study of quantum backflow in the Rindler spacetime.

Summary: This paper investigates the orbits of charged particles near the event horizon of a magnetized black hole. The dimensionless parameter b 1/4 eBGM/(mc4) determines the radius of the circular orbits and the position of the innermost stable circular orbit (ISCO). The properties of these orbits can be effectively determined using a near-horizon approximation, and the effective potential governing the position of the orbit is universal under rescaling of the magnetic field. The particle orbits in the near-horizon approximation are stationary worldlines in Minkowski spacetime, and the lifetime of the particle before reaching the ISCO and falling into the black hole can be evaluated by considering the slow changes in the distance of the particle orbit from the horizon due to the electromagnetic field radiated by the particle.

Summary: This study develops a unified framework to describe the complex diversity in atmospheric black carbon (BC) morphology and composition using a phase shift parameter. The framework provides a computationally inexpensive method to estimate BC absorption and has been packaged into an open-source Python application. Analysis of field and laboratory data reveals that rho BC > 1 leads to decreased absorption by BC, explaining weaker absorption enhancements observed in certain regions. The framework can be used to constrain BC light absorption throughout its atmospheric lifetime.

Summary: The study found that despite different calcium carbonate distributions and morphological features, the clay mineral composition in soils developed on menilite shales slope deposits was very uniform, with secondary phases such as chlorite, illite, vermiculite, kaolinite, and mixed phases present in all horizons. This suggests a similar mass movement controlling the slope covers formation and a consistent scale of pedogenesis advancement across all soils. The weak intensity of illuviation process within the homogeneous substrate may have contributed to the uniform composition of clay minerals in the soils.

Summary: This study examined the potential toxic elements (PTE) in Arctic soils and their origin. The results showed that the pollution in the soils was anthropogenic in nature and had a higher concentration in areas closer to the coastlines. Both local factors, such as parent material, and long-distance factors, such as wet deposition from European industrial centers, were found to contribute to the enrichment of PTE in the soils. Monitoring and assessing the quality of Arctic soils is important for identifying the sources of PTE pollution and developing methods for their protection and maintenance.

Summary: Loess landscapes in south-western Poland provide insights into the record of denudation processes. Soil redeposition events occurred around 9.1 ka, followed by denudation events attributed to different historical periods. The soil cover in the area has been reshaped, with predominant Luvisols experiencing progressive erosion processes. Modern soil erosion rates have significantly increased, potentially leading to a complete transformation of the Luvisol status within approximately 80-300 years.

Summary: By studying soil samples from different slope directions along an elevational gradient in a mountain ecosystem, we found that soil bacterial diversity and microbial functions exhibit distinct elevational patterns, which are consistent across slope directions. The bacterial diversity shows a hump-shaped pattern, while microbial functions exhibit a linear increasing trend. Additionally, the beta diversity pattern of soil bacteria is significantly influenced by elevational distance decay relationships. Soil bacterial diversity patterns are determined by transitions in community assembly processes, whereas microbial functions are mainly influenced by bacterial community composition.

Summary: Soil respiration plays a crucial role in the global carbon cycle in arid and semi-arid regions, and is regulated by hydrothermal factors. This study examined the seasonal and diurnal dynamics of soil respiration in two typical ecosystems in northern China, and investigated their responses to precipitation, temperature, and drought. The results showed that soil respiration varied seasonally and diurnally, and its response to environmental factors depended on the ecosystem type and soil moisture status. Incorporating multiple factors into carbon cycle models can improve the simulation and prediction of carbon emissions in arid and semi-arid regions.

Summary: Lake drawdown areas, where sediment is exposed due to water level fluctuations, have a significant impact on the carbon cycle. This study examined microbial necromass carbon (MNC) content and its contribution to soil organic carbon (SOC) in different habitats within the drawdown area of Dongting Lake. The results showed that MNC content varied among habitats and was primarily influenced by carbon and nitrogen availability, plant biomass, clay content, and soil moisture. External factors, such as plant and soil properties, played a more crucial role in the long-term accumulation of MNC. These findings enhance our understanding of MNC stability in drawdown areas.
