Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

PLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Effectiveness of model‐based decision tools for disease control in wheat, potato and grapevine: a multilevel meta‐analysis

Pest Management Science, EarlyView.
Meta‐analysis results indicate that decision tools can provide effective disease control, although their performance may vary among crops. Despite differences, decision tools reduced the Treatment Frequency Index across three crops. Abstract BACKGROUND A multilevel meta‐analysis was conducted to provide further evidence on the benefits of decision ...

Revisiting bare‐ground evaporation in a high‐resolution numerical weather prediction system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An improved method is proposed to parameterize evaporation in numerical weather prediction models. The figure shows dew‐point temperature forecast error (standard deviation of forecast error and bias) versus lead time over the North Plains region during spring 2022 for three parameterizations: CTL, the α$$ \alpha $$ method of Jacquemin and Noilhan; IFS:

Modeling of Surface Structure Formation after Laser Irradiation

The Stefan problem in a semi-infinite media under laser irradiation is consideres. It is related to the melting and solodification processes, resulting in certain surface structure after the solidification. A simple model, as well as a more sophisticated

Adaptive Sliding‐Mode Control of a Perturbed Diffusion Process With Pointwise In‐Domain Actuation

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT A sliding mode–based adaptive control law is proposed for a class of diffusion processes featuring a spatially‐varying uncertain diffusivity and equipped with several point‐wise actuators located at the two boundaries of the spatial domain as well as in its interior.

Passive Acoustic Identification of Social Groups in the Hainan Gibbon

Remote Sensing in Ecology and Conservation, EarlyView.
Passive acoustic monitoring offers a non‐invasive means of assessing visually hard‐to‐survey wildlife species with distinctive vocalizations. We evaluated whether deep learning can identify Hainan gibbon (Nomascus hainanus) social groups from their calls.
