The whisker somatosensory system in awake, behaving rodents is a powerful model for studying neurobiology of sensation, from molecules to circuits to behavior. Recent studies reveal how key tactile features are detected in awake animals and encoded by spike trains in somatosensory cortex (S1). Here we summarize progress on detection of surface texture (roughness). Texture appears to be inferred...

Network coding is a data transmission technique which allows intermediate nodes in a network to re-code data in transit. In contrast to traditional network communication where a node repeats incoming data to its outgoing channel without modifying the payload, a node implementing network coding not only repeats but also alters data. Network coding has been demonstrated to increase network throug...

The NGCS is based on neuroscience research. While previous gesture classification systems were developed on the basis of gesture observation and their categories were heuristical, the NGCS links the phenomenology to the neurobiology of gestures. The theoretical assumption behind the NGCS is that its main kinetic and functional gesture categories are differentially associated with specific cogni...

Discrete Multitone (DMT) modulation is a multicarrier technique which makes efficient use of the channel, maximizing the throughput by sending different numbers of bits on different subchannels. The number of bits on each subchannel depends on the Signal-to-Noise Ratio of the subchannel. The performance of a DMT system can be further increased by using powerful coding techniques. This thesis in...

This paper is focused in the effect of adaptive weighted non-linearity in speech coding. The results showed that the effect of adaptive non-linearity improves the spectral distance measure when compared to the system without non-linearity. Key-Words: Coding, Non-linearity, Hammerstein Model, Adaptation

In this paper, the combination of equalization and turbo decoding is studied. In the iterative decoding of a product code in block turbo coding system, the equalization process is performed within the iteration loop. The present study aims to investigate the decision feedback equalizer (DFE) incorporated in the iterative decoding. Simulation results show that the more severe the channel interfe...

this research aims to develop a theory of talent management. the research method is qualitative based on grounded theory. data were gathered in investment market as theoric sampling and 16 interviews were done by managers of investment market. the results of open, axial and selective coding lead to develop dual-core hr architecture theory. based on this theory, organizations should differentiat...

micrornas (mirnas) are small preserved non-coding rna molecules that regulate gene expression post-transcriptionally by targeting the 3' utr of mrnas for translational repression or degradation. the rising evidence has established the significant role of mirnas within the regulation of immune system and the prevention of autoimmunity. mir-146a has obtained an importance as a modulator of d...

a self-regulated high-copy number plasmid containing chloramphenicol resistant gene, for the production of recombinant proteins under the regulation of bacteriophage ?pl promoter, was constructed. the designed 5024 base pair expression plasmid contained a heat sensitive repressor ci857 coding gene to regulate the function of ?pl promoter under heat shock induction. using the constructed vector,...
