Patch antennas on inhomogeneous substrates

Patch antennas on inhomogeneous substrates are analyzed with the stable FEM-FDTD hybrid method [T. Rylander and A. Bondeson, “Stable FEMFDTD hybrid method for Maxwell’s equations,” Comput. Phys. Comm. 125, 75 (2000)] and an analytic propagator technique. For inhomogeneous substrates with a fixed homogenized value of the permittivity, our results conjecture that a decrease of the permittivity in the

Carbon stocks and fluxes in a young Siberian larch (Larix sibirica) plantation in Iceland

The understanding of how forests function with respect to carbon (C) balance and its interaction with the climate system is a fundamental question in climate change research. Another important question is how large the sink for CO2 is in northern forests and how it varies with forest type, management, stand age and with external factors, such as climate variability. According to the Kyoto Protocol

Physiological and behavioral responses in human fear of bears and wolves.

Research on human emotions towards large carnivores is often based on self-reported emotions. This study aimed to investigate physiological and behavioral responses to feared animals among people who say that they are fearful or not fearful of brown bear and wolf. Participants were recruited to be bear fearful only (n=8), fearful of both bear and wolves (n=15), or fearful of neither carnivore (n=1
