“…This difference is attributed to higher numerical noise levels produced by Method 2 with regard to Method 1. If it were desired to improve the performance of Method 2 at such small , this could be done by decreasing the Courant number [1] and optimizing the parameters (such as conductivity profile and number of layers) of perfectly matched layers (PMLs) absorbing boundary conditions [15]. However, the use of step is usually more than enough for the most exigent FDTD simulations [1].…”

“…For V/m, we obtain 97.2% and 97%. Since the losses increase as increases, they are attributed to a PML numerical artifact often observed in numerical models at high power levels [15]. Fig.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…A limitation of this approach, however, is that it does not apply to nonlinear media. For a recent (non-Maxwellian) extension of the PML to nonlinear media, see [20].…”
