Ecological Solutions and Evidence, Volume 7, Issue 1, January–March 2026.Careful woodland design can avoid planting on high‐carbon soils. In the Yorkshire Dales, tree planting targeted lower SOC areas, showing new guidelines and standards help protect soil carbon in upland woodland creation. Abstract Tree planting is a key climate mitigation strategy, but afforestation on organo‐mineral soils may cause soil organic carbon ...

The Role of Leaf Wettability and Morphology on Leaf Surface Water Storage: A Cross‐Biome Synthesis
Ecohydrology, Volume 19, Issue 1, January‐February 2026.ABSTRACT The presence of water on leaves impacts plant function and ecosystem fluxes by supplementing moisture, reducing evapotranspirational demand and encouraging pathogen spread. Maximum phytoelement water storage capacity (MWSC)—the maximum amount of water that can be held on the surface of the leaf‐ is an important but poorly constrained parameter

A UKF Algorithm Based on the Singular Value Decomposition of State Covariance
, 2010 One of the existing problems of General UKF is the stability problem due to the strong nonlinearity and the complexity of the system. When the algorithm can't ensure the state covariance to be positive semidefinite, the precision will be decreased or

UKF-based MEMS micromirror angle estimation for LiDAR
Journal of Micromechanics and Microengineering, 2019 Azimuth and distance measurement are two key technologies of MEMS LIDAR. In order to improve the accuracy of (micro-electronical mechanical system scanning mirror) MEMS-SM angle measurement, this paper proposes an angle estimation algorithm based on ...

Italian National Conference on Sensors, 2017 In this paper, we propose a cost-effective localization solution for land vehicles, which can simultaneously adapt to the uncertain noise of inertial sensors and bridge Global Positioning System (GPS) outages. First, three Unscented Kalman filters (UKFs)

Adaptive UKF and Its Application in Fault Tolerant Control of Rotorcraft UAV
, 2007 Fault tolerant control (FTC) is essential for rotorcraft UAV (RUAV). Due to the inherently unstable dynamics, either flight test or real application of a RUAV is in high risk while a minutial failure may lead to the whole system collapse.

Adaptive Unscented Kalman Filter for Target Tracking with Unknown Time-Varying Noise Covariance
Sensors, 2019 The unscented Kalman filter (UKF) is widely used to address the nonlinear problems in target tracking. However, this standard UKF shows unstable performance whenever the noise covariance mismatches.
