The effects of the membrane-permeable dibutyryl guanosine 3', 5'-cyclic monophosphate (db-cGMP) on the bombykol-elicited receptor current and nerve impulse activity were studied using the open sensillum recording technique. db-cGMP was applied to the outer dendritic membrane of the olfactory receptor neuron of the moth Bombyx mori. db-cGMP reduced the amplitude of the overall receptor current a...

Impulse noise is caused by errors in the data transmission generated in noisy sensors or communication channels, or by errors during the data capture from digital cameras. Noise is usually quantified by the percentage of pixels which are corrupted. Corrupted pixels are either set to the maximum value or have single bits flipped over. In some cases, single pixels are set alternatively to zero or...

In identification or model reduction problems, an important task is the computation of the characteristic polynomial of the original or reduced-order system. Several literature have shown that the characteristic polynomial of a system can be extracted from the information generated by the impulse response data. For continuous systems, the Gram matrix [1,2] and the impulse response Gramian [3] a...

abstract various mathematical water uptake models have been introduced for plants response to combined drought and salinity stress. the reduction functions are classified as additive, multiplicative and conceptual models. in this study six different macroscopic reduction functions, namely; van genuchten (additive and multiplicative), dirksen et al., van dam et al, skaggs et al and homaee were e...

Image Processing is a technique to enhance raw images received from cameras/sensors placed on satellites, space probes and aircrafts or pictures taken in normal day-to-day life for various applications. Impulse noise reduction method is one of the critical techniques to reduce the noise in color images. In this paper the impulse noise reduction method for color images by using Fuzzy Logic is im...

The fly has a receptor cell highly specialized for the taste of sugars. We introduced inositol 1,4,5-trisphosphate (IP3), Ca2+, or a phorbol ester, 12-deoxyphorbol 13-isobutylate 20-acetate (DPBA), into the cell and investigated their effects on the response to sucrose. The sugar receptor cell generates impulses during constant stimulation with sucrose, but the impulse frequency gradually decli...

1 This work is supported by national natural science foundation of China, No.60475036. Abstract –The noise detection model is build up by using SVM-based fuzzy inference system for detecting the impulse noise in an image. The support vectors which are used to confirm the fuzzy basis function and create the corresponding fuzzy rules are extracted from the training samples by the learning mechani...

We proposed a blind dereverberation method based on spectral subtraction byMulti-Channel Least Mean Square (MCLMS) algorithm for distant-talking speech recognition in our previous study [1]. In this paper, we discuss the problems of the proposed method and present some solutions. In a distant-talking environment, the length of channel impulse response is longer than the short-term spectral anal...

seismic waves travelling through inelastic media are attenuated by the conversion of elastic energy into heat. upon being attenuated, the travelling wave changes: amplitude is reduced, travelling waveform is modified due to high-frequency content absorption, and phase is delayed. attenuation is usually quantified through the quality factor q: the ratio between the energy stored and lost in each...
