We have successfully aligned single-walled carbon nanotubes (SWNTs) in patterns with nanoscale width, micron-scale length and controllable pitch on SiO2/Si substrates using a poly(dimethysiloxane) (PDMS) microchannel mold. The microchanneled mold was patterned with a funnel-shaped channel to minimize nanotube jamming during capillary-driven inflow. Two (i.e. preand post-capillary) gas blows wer...

Neural representation of pitch-relevant information at both the brainstem and cortical levels of processing is influenced by language or music experience. However, the functional roles of brainstem and cortical neural mechanisms in the hierarchical network for language processing, and how they drive and maintain experience-dependent reorganization are not known. In an effort to evaluate the pos...

This study aims at investigating the interface between emotion and intonation patterns (more specifically, duration and pitch amplitude of speech). To this end, the acoustic properties of spectral parameters related to speech prosody are investigated. The results of acoustic and Statistical analysis show that mean level and range of FO in the contours vary strongly as a function of the degree o...

A discussion of tonal categories relating to pitch perception discrimination thresholds focuses on the differences between pitch perception per se and the perception of tonal timing. In the light of several experimental studies on the perception of tonal timing categories in different languages, it is hypothesized that the perception of level tones can be related to the highly acute psychophysi...

Single-channel speech enhancement is often formulated in the Short-Time Fourier Transform (STFT) domain. As an alternative, several previous studies have reported advantages of speech processing using pitch-synchronous analysis and filtering in the modulation transform domain. We propose to use the Double Spectrum (DS) obtained by combining pitchsynchronous transform followed by modulation tran...

Considering the difficulties in planar CMOS transistor scaling to secure an acceptable gate to channel control FinFET based multi-gate (MuGFET) devices have been proposed as a technology option for replacing the existing technology. The desirability of FinFET that it’s operation principle is same as CMOS process. This permits to lengthening the gate scaling beyond the planar transistor limits, ...

In this paper, we present our speaker verification (SV) systems for the cross-channel text-independent and dependent speaker verification (TI-SV and TD-SV) tasks of ISCSLP’2006 speaker recognition evaluation (ISCSLP2006-SRE). To address the cross-channel issues and take advantage of the unique characteristics of Mandarin (i.e., tonal language), prosodic contours are modeled to assist the state-...

Although pitch is a fundamental auditory percept that plays an important role in music, speech, and auditory scene analysis, the neural codes and mechanisms for pitch perception are still poorly understood. In a previous study (Cedolin and Delgutte 2005), we tested the effectiveness of two classic representations for the pitch of harmonic complex tones at the level of the auditory nerve (AN) in...
