“…Other typical ER algorithms include EPRCA with Explicit Rate Indication, Explicit Rate Indication for Congestion Avoidance (ERICA) [3], and Congestion Avoidance using Proportional Control (CAPC) [4]. An extensive simulation analysis of these ER schemes' performance was presented by Kawahara [5]. The major performance limitations of these algorithms include ad hoc rate computation, slow response, excessive buffer requirement, and difficulty in tuning the control parameters.…”

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.

“…This scenario is an extremely stressful test for ABR algorithms where responsiveness, stability and fairness can be evaluated. Reference [2] evaluates all the algorithms considered with an RIF of 1/16. To produce more stressful and aggressive test conditions, we use an RIF of 1.0 (maximum value).…”
