Summary: The seasonal dynamics of the freeze-thaw front during the freezing and thawing period strongly affect the hydrothermal processes in permafrost regions. This study analyzed the freeze-thaw front dynamics using field observation data in the Qinghai-Tibet Plateau. Changes in the freeze-thaw front were characterized by three distinct stages: the downward migration of the thaw front, zero curtain process at the bottom of the active layer, and the bidirectional freezing period. The findings provide insights into the hydrothermal characteristics of the active layers in permafrost regions and can improve future permafrost simulation models.

Summary: An investigation of an active layer detachment slide (ALDS) on the Qinghai-Tibet Plateau (QTP) revealed that it was likely triggered by the intersection of a layer with high ice content and a thaw depth. The minimum downslope velocity of the main slide mass was approximately 20 m/h, and it collided with the embankment of the Qinghai-Tibet Railway (QTR).

Summary: This study used stable isotope techniques to investigate saline lakes on the Qinghai-Tibet Plateau (QTP) and found significant spatial variability in their stable isotopes due to the source of water vapor, recharge patterns, and local evaporation conditions. The average water vapor recycling ratio of saline lakes on the QTP was 20.16%, with some lakes exceeding 30%. Saline lakes lose 26% of their water through evaporation, with 26% experiencing high evaporation losses of over 40% of the total inflow. Precipitation and altitude were identified as the main factors controlling the water vapor recycling ratio and evaporation loss, respectively, with significant differences found between saline lakes above and below 4500 m elevation.

Summary: This study investigates the effects of soil wetting and granularity on the changes in active layer thickness (ALT) and assesses the spatiotemporal dynamics of ALT on the Qinghai-Tibet Plateau (QTP). The results show that soil wetting slows down the thickening of the active layer in response to warming, and latent heat has a stronger control on ALTs compared to thermal conductivity. Additionally, under similar warming conditions, coarse soils have a faster thickening rate than fine soils.

Summary: Thermokarst lakes are formed by the degradation of ice-rich permafrost. This study used time series InSAR analysis to characterize the spatial-temporal variations of surface deformation in the Beiluhe Basin in the Qinghai-Tibet Plateau and extracted thermokarst lakes. The results showed that the density of thermokarst lakes is positively correlated with the linear subsidence rate, seasonal deformation amplitude, and active layer thickness.

Summary: This study revealed that ground temperatures of permafrost island on the Qinghai-Tibet Plateau were significantly higher compared to nearby marginal permafrost and continuous permafrost, showing a continuous increase over the past 8 years. The disappearance of the permafrost island in 2018 was attributed to the persistent increase in active-layer thickness, decrease in permafrost table depth, and anomalously high air temperatures in 2016 and 2017.

Summary: Due to its high safety and low cost, aqueous Zn-ion batteries (AZIBs) have become one of the most promising energy storage devices. In this study, a stable cathode with fast kinetics and high-energy density, KOH-induced oxygen-deficient VO2 (K-VO2), was developed. The K-VO2 cathode achieved improved kinetics and enhanced Zn-ion storage capability through unique morphology, abundant active sites, and oxygen vacancy. The optimized K-VO2-3:4 demonstrated excellent electrochemical performance, indicating the potential of the KOH activation strategy for developing high-energy and stable cathodes.

Summary: Numerous studies have been conducted to evaluate and project permafrost changes based on CMIP datasets. However, the lack of verified data has led to over-projection of permafrost changes in CMIP3 and CMIP5. Moreover, future permafrost changes in CMIP6, especially on the Qinghai-Tibet Plateau, remain unknown. To address this, the study evaluated and calibrated monthly ground surface temperature (GST) based on in situ measurements, and found that the calibrated GST performed better than the CMIP6 models. The reconstructed GST data series could be used to simulate long-term permafrost temperature over the Qinghai-Tibet Plateau. Rating: 7/10

Summary: Most studies have focused on the mechanism of changes in frozen soil and the contribution of climate change, hydrological processes, and ecosystems in cold regions. Although there have been improvements in simulating water and heat transfer processes in cold regions, differences still exist among models and parameterizations due to the lack of observations and understanding. Further research is needed to enhance the accuracy of parameterization and improve the understanding of water and heat transfer processes in frozen soil.

Summary: Climate changes significantly impact the hydrological cycle, especially when it comes to precipitation. This study investigates the relationship between temperature and daily precipitation in different percentile ranges over the Qinghai-Tibet Plateau. The results show that precipitation type and regional factors play a role in this relationship, and higher percentiles of daily precipitation have a larger positive scaling rate than lower percentiles. The findings help in understanding the impact of climate change on the hydrological cycle in this region.

Summary: Thermal conductivity, an important soil property, is widely used in agricultural production, land surface processing research, and geothermal resource development. However, there is no unified model for different soil types. To overcome data shortage, this study established a comprehensive lambda dataset and identified 10 influential parameters. A comparison was made between classical parametric models and machine learning models, with the ensemble machine learning methods performing better. The XGBoost model showed better simulation accuracy and generalization capability. The results can provide basic thermal conductivity data and a parameterization scheme for land surface processing research.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
