Interaural-delay sensitivity to high-frequency (> or = 3 kHz) sinusoidal-frequency-modulated (SFM) tones is examined for rates from 25 to 800 Hz and depths of -12 to 18 dB. Comparison is made to thresholds obtained for sinusoidal-amplitude-modulated (SAM) tones for the same observers and modulation rates. Both SAM and SFM threshold-by-rate functions are U-shaped with optimum sensitivity to SFM ...

A phenomenological model with time-varying excitation and inhibition was developed to study possible neural mechanisms underlying changes in the representation of temporal envelopes along the auditory pathway. A modified version of an existing auditory-nerve model [Zhang et al., J. Acoust. Soc. Am. 109, 648-670 (2001)] was used to provide inputs to higher hypothetical processing centers. Model ...

Recently reported plasmon-induced transparency (PIT) in metamaterials endows the optical structures classical systems with quantum effects. In particular, nonreconfigurable nature makes multifunctional applications of PIT effects terahertz communications and networks remain a great challenge. Here, we present an ultrafast process-selectable modulation effect. By incorporating silicon islands in...

A polarization-insensitive graphene-assisted electro-optic modulator is proposed. The orthogonal T-shaped metal slot hybrid plasmonic waveguide allows the polarization-independent propagation of transverse electric field mode and complex mode. By introduction dual-layer graphene on ridge waveguide, modulation depths TE are 0.511 dB/µm 0.502 dB/µm, respectively. 3 dB bandwidth we have proposed a...

This paper develops a new class of functional depths. A generic member this is coined $J$th order $k$th moment integrated depth. It based on the distribution cross-sectional halfspace depth function in marginal evaluations (in time) random process. Asymptotic properties proposed depths are provided: we show that they uniformly consistent and satisfy an inequality related to law iterated logarit...
