Summary: The quantification of soil organic matter (SOM) has been increasing in the Brazilian Cerrado region, where SOM content tends to be low. This study evaluated the performance of a local spectral model for SOM prediction using spectroradiometry. The results showed that recalibration of the local models improved the prediction accuracy, but further research is needed to improve the identification of SOM spatial variability.

Summary: The study analyzed the behavior and contamination risk of potentially harmful metals in the Thessaly plain based on soil samples collected from 2013 to 2017. Vertical distribution of metals and prediction models for Fe and Cd concentrations were established using robust quadratic regression analysis, showing the impact of soil properties on metal distribution in the area. The study concluded that the regression equations are a useful tool for managing and predicting pollution in the studied area.

Summary: The study presents a general computational method for constructing maps between different cell fates and parametric conditions by systematic perturbations. The method does not require accurate parameter measurements or bifurcations. The maps obtained can help in understanding how systematic perturbations drive cell fate decisions and transitions, providing valuable information for predicting and controlling cell states.

Summary: This study investigated the capability of a new hyperspectral imager, ZY1-02D, to estimate and map topsoil N content in black soil farmlands in northeast China. The results showed that sensitive bands modeling can enhance estimation accuracy and simplify the model, demonstrating the ideal capability of ZY1-02D for soil N content estimation at the regional scale.

Summary: The introduction of exotic plants and improper management strategies can alter the soil-water balance and lead to the formation of dried soil layers. This study in the Loess Plateau of China found that gullies significantly influenced the depth and spatial patterns of dried soil layers. Soil properties, particularly clay and silt content, were identified as key factors influencing the formation of dried soil layers.

Summary: In this article, the relationship between partial least squares (PLS) and other regularized regression algorithms such as Lasso and ridge regression is explored. A steepest descent alternative to the PLS algorithm is also considered. The emphasis is placed on PLS latent variable analysis and its connections to conjugate gradient, Krylov space, and matrix pseudo-inverse using existing literature. Comparison of PLS with Lasso and ridge regression is conducted in terms of different resolutions along the regularization paths, providing insights into why PLS may not always outperform the other algorithms. A steepest descent PLS is proposed as a regularized regression alternative and evaluated against other algorithms through simulations and an industrial case study.

Summary: This article provides an overview of alternative methods for restoring contaminated soils (phytoremediation), focusing on areas of excessive metallurgical activities in Greece. Two case studies in Northern Greece were selected, one characterized by metal mining and a hot summer Mediterranean climate, and the other involving lignite mining and pollution under subtropical climate.

Summary: Exposure to potentially toxic elements (PTEs) via dust inhalation in the streets of Kashan, Iran poses a risk to human health. The study found that residents of Kashan are facing considerable carcinogenic risk due to high concentrations of PTEs in street dust, highlighting the need for control measures to reduce emissions of PTEs.
