Summary: Terrestrial laser scanners (TLS) record a large number of points within a short time, but temporal correlations are often neglected leading to potential errors in deformation analysis. It is suggested that Hurst exponent can be used to model noise of range measurements and scanning settings can affect global correlation parameters. By combining two Hurst-estimators, a simple global model for describing temporal noise in TLS range correlations can be established.

Summary: As one of the largest and most typical continuous karst distribution belts in the world, Southwest China is susceptible to soil erosion and rocky desertification due to its unique geological conditions and heterogeneous landscapes. This study aims to assess the variability of sediment yield in selected karst watersheds and identify the rainfall and runoff variables that are most associated with sediment yield. The findings demonstrate that sediment yield is significantly influenced by rainfall and runoff, with specific rainfall and runoff variables playing dominant roles in different karst watersheds.

Summary: This study evaluates the temporal effect of different soil matric potential thresholds on the marketable yield and irrigation water productivity of container-grown potatoes. The results suggest that a comfort zone maintaining soil matric potential between -10 and -24 kPa maximizes potato yield while reducing irrigation water use. The leaf expansion and tuber initiation stages are identified as the periods where daily soil matric potential has the most influence on the marketable yield.

Summary: This study proposes two time-space domain implicit staggered-grid finite-difference schemes for 2-D elastic wave simulation. The schemes approximate spatial derivatives using weighted average and estimate finite-difference coefficients using variable substitution-based Taylor-series expansion, achieving high-order temporal and spatial accuracy. Furthermore, the spatial accuracy is enhanced using linear optimization strategy, and P- and S-wave separation approach is adopted for better numerical dispersion suppression and stability performance.

Summary: Although many advanced analytical methods have been used to study soil organic matter (SOM), its highly complex and heterogeneous chemical composition remains elusive. Analytical thermal analysis, such as differential scanning calorimetry (DSC) and evolved gas analysis (EGA), can provide valuable insights into SOM characterization. This study aimed to enhance the interpretation of DSC and EGA results using spectral correlations with solid-phase ^13C NMR data. The comparisons between well-understood NMR spectra and less-understood DSC and EGA thermograms shed light on the combustion temperatures of different chemical compounds in SOM.

Summary: Innovations in CMOS SPAD technology have contributed to the development of advanced instruments for TRFS. These instruments can collect fluorescence intensity and fluorescence lifetime information across a broad spectral range with high resolution. We introduce MuFLE, a computational method that efficiently utilizes multi-channel spectroscopy data to estimate emission spectra and spectral fluorescence lifetimes simultaneously. Furthermore, we demonstrate that this approach can extract individual spectral characteristics from mixed samples.

Summary: The genomic selection methodology has revolutionized plant breeding by using statistical machine learning algorithms to predict candidate individuals. However, it faces challenges when predicting future seasons or new environments. This study compared the performance of the multi-trait partial least square (MT-PLS) regression method with the Bayesian Multi-trait Genomic Best Linear Unbiased Predictor (MT-GBLUP) method and found that MT-PLS outperforms MT-GBLUP in predicting future seasons or new environments.

Summary: Radargrammetry is a useful approach for generating Digital Surface Models (DSMs) and offers an alternative to InSAR techniques. Stereo image matching plays a crucial role in determining the quality of DSMs for spatial-temporal analysis of landscapes and terrains. We propose a hierarchical semi-global matching (SGM) pipeline to reconstruct DSMs in forested and mountainous regions using stereo TerraSAR-X images.

Summary: Proteomics is a powerful tool for understanding disease mechanisms and identifying biomarkers. In this study, Tandem Mass Tag-based quantitative analysis was used to identify differentially expressed proteins in the cortical proteome of mice with traumatic brain injury (TBI). The results showed that TBI was associated with a significant number of differentially expressed proteins involved in inflammatory responses. Transcription factor analysis revealed the pivotal role of NF-kappa B1, RelA, IRF1, STAT1, and Spi1 in the secondary injury caused by TBI. The findings suggest that inflammation-related proteins and inflammatory responses are promising targets for the treatment of TBI.

Summary: The study aims to investigate the phagocytosis of synapses by astrocytes in the ipsilateral hippocampus after traumatic brain injury (TBI). Through controlled cortical impact in mice, the researchers found a reduction in excitatory postsynaptic materials in the ipsilateral hippocampus during the subacute stage post-TBI, which was associated with cognitive dysfunction. They also identified phagocytic astrocytes containing secondary lysosomes wrapped around synapses and an increase in the co-location of GFAP and PSD-95, suggesting astrocytic engulfment of synaptic proteins. The study highlighted the role of Megf10 in astrocytic engulfment and its contribution to cognitive dysfunction following severe TBI in the CA1 region of the ipsilateral hippocampus.

Summary: Quantifying the kinematic evolution patterns of mountain glaciers is crucial for assessing glacial instability and secondary disasters. In the Sedongpu Basin near the Yarlung Tsanpo River Valley, the dominant texture deficiencies caused by ice-rock avalanche events were visually identified. To improve image correlation quality, a stepwise combination strategy was used to derive glacier displacement velocities from Landsat-8/Sentinel-2 optical images. The displacement velocities varied significantly before each collapse event, and the dynamic mechanism of active glaciers followed a power law. This study sheds light on interpreting the precursory displacement patterns and failure mechanism of ice-rock avalanche events using optical and SAR observations.

Summary: A deeper understanding of the underlying biological mechanisms of secondary brain injury induced by TBI, especially the role of HIF-1 alpha in regulating neuroinflammation, could advance the development of effective treatments for TBI patients. This study utilized next-generation sequencing and cellular analysis to investigate HIF-1 alpha-mediated events in a rat TBI model. The results demonstrated that TBI induced the accumulation of HIF-1 alpha and neuroinflammation, and the inhibition of HIF-1 alpha could attenuate these effects, suggesting its contribution to secondary brain injury.
