For mobile speech application, speaker DOA estimation accuracy, interference robustness and compact physical size are three key factors. Considering the size, we utilized acoustic vector sensor (AVS) and proposed a DOA estimation algorithm previously [1], offering high accuracy with larger-than-15dB SNR but is deteriorated by nonspeech interferences (NSI).(More)
Behavioral evidence supports a role for peripheral glutamate receptors in normal nociceptive transmission. In this study, we examined the release of the excitatory amino acids, glutamate and aspartate, in the s.c. perfusate of the rat hind instep by in vivo microdialysis. Antidromic stimulation of the sciatic nerve and noxious stimuli in the form of heat(More)
A-alpha-CAO induces weak analgesia with very short duration in mice and is able to antagonize the analgesic effect of morphine (Mor) up to 3-4 days after a single injection. No tendency of dependence has been observed. It acts as a partial agonist on MVD with Ke value of 9 X 10(-9) mol/L. Its antagonist effect remains after several washes and its agonist(More)
