Nonlocal active sound control for composite regions
Mathematical Methods in the Applied Sciences, EarlyView.In the active sound control problem, additional sound sources, known as control sources, are implemented at the perimeter of a protected domain. The control sources can generate secondary sound inside the shielded domain, which attenuates incoming noise. This leads to an inverse source problem.

Connecting the dots: Network structure as a functional trait in arbuscular mycorrhizal fungi
PLANTS, PEOPLE, PLANET, EarlyView.Soil health and sustainable land management are critical to addressing global challenges such as food security, climate resilience, and biodiversity loss. Arbuscular mycorrhizal (AM) fungi form underground networks that enhance plant nutrient uptake and improve soil structure, yet their functional diversity remains poorly understood, limiting their ...

Efficient modeling of antennas with finite conductivity using calderón preconditioning [PDF]
, 2018 A Calderon preconditioner for a novel single-source integral equation, which allows the simulation of high dielectric contrasts and lossy conductors, is introduced. It is shown that this preconditioner avoids breakdown when simulating scattering problems

Covariates influence optimal camera‐trap survey design for occupancy modelling
Remote Sensing in Ecology and Conservation, EarlyView.We investigated the impact of covariates (e.g., habitat quality, temperature) on the optimal design of camera trap surveys to estimate species occupancy. Using simulations of a virtual species, we found that increasing the number of cameras consistently reduced error across a range of covariate effects.
