Networks of neurons in the cerebral cortex operate in regime that are typically characterized by high levels of ‘noise’. Contrary to many sources of noise in physical systems, the neuronal noise is generated for the most part internally, through the highly irregular nature of neuronal discharges, in awake animals in particular. It is still highly debated how neurons and populations of neurons m...

Noise removal operation is commonly applied as pre-processing step before subsequent image processing tasks due to the occurrence of noise during acquisition or transmission process. A common problem in imaging systems by using CMOS or CCD sensors is appearance of  the salt and pepper noise. This paper presents Cellular Automata (CA) framework for noise removal of distorted image by the salt an...

The small GTPase Ras plays an important role in many cellular signaling processes. Ras activity is negatively regulated by GTPase activating proteins (GAPs). It has been proposed that RasGAP may also function as an effector of Ras activity. We have identified and characterized the Drosophila homologue of the RasGAP-binding protein G3BP encoded by rasputin (rin). rin mutants are viable and displ...

Here we demonstrate theoretically that stimulated Brillouin scattering (SBS) can induce a phase shift of the optical carrier relative to its sidebands due to the waveguiding effect of the optical fiber on the acoustic wave. This causes conversion of frequency modulation to intensity modulation, which results in an increase in the relative intensity noise and degradation of the modulation respon...

Recent studies suggest that fruit cuticle is an important contributing factor to tomato (Solanum lycopersicum) fruit shelf life and storability. Moreover, it has been hypothesized that variation in fruit cuticle composition may underlie differences in traits such as fruit resistance to desiccation and microbial infection. To gain a better understanding of cuticle lipid composition diversity dur...

The results of an experimental study the effects noises on flows in a rotating spherical layer are presented. Noise is introduced into flow form random fluctuations inner sphere rotational rate relative to time constant mean value. velocity was measured with laser Doppler anemometer. It found that equal amplitude, but different spectra cause generation intensity. shown increase average velociti...

Recently, we have found that the accumulation of ripening inhibitor (RIN) protein increased gradually during tomato fruit ripening. Here, the recombinant protein was expressed in Escherichia coli and affinity-purified. The DNA binding activity of renatured RIN protein was tested by electrophoretic mobility shift assay. The results indicated that an optimal expression and purification system was...
