Structured illumination microscopy (SIM) is a very important super-resolution technique, which provides high speed with about two-fold spatial resolution enhancement. Several attempts aimed at improving the performance of SIM reconstruction algorithm have been reported. However, most these highlight only one specific aspect -- such as determination pattern phase shift accurately whereas other key elements modulation factor, estimation object power spectrum, Wiener filtering frequency...

Structured illumination microscopy (SIM) achieves doubled spatial resolution through exciting the specimen with high-contrast, high-frequency sinusoidal patterns. Such an pattern can be generated by laser interference or incoherent structured Opto-electronic devices, such as a Spatial Light Modulator (SLM) Digital Micro-mirror Device (DMD), provide rapid switch of patterns for SIM. Although DMD is much more cost-effective than SLM, it was previously restricted in association light sources,...

Conventional 2D structured illumination microscopy (SIM) requires nine raw images to reconstruct a super-resolved image. In order increase the frame rate of SIM, attempts are being made reduce number SIM images. However, all proposed reconstruction algorithms (SIM-RA) capable reconstructing super-resolution (SR) image with reduced operate in spatial domain. Here, we present frequency domain SIM-RA based on ordinary least squares technique, which enables SR using four Unlike RA, produces...

We developed a dual oscillator model to facilitate the understanding of dynamic interactions between parafacial respiratory group (pFRG) and preBötzinger complex (preBötC) neurons in rhythm generation. Both neuronal groups were modeled as 81 interconnected pacemaker neurons; bursting cell described by Butera others [model 1 et al. (J Neurophysiol 81:382-397, 1999a)] used neurons. assumed (1) both pFRG preBötC networks are generators, (2) receives excitatory inputs from pFRG, inhibitory...

We hypothesize that the network topology within pre-Bötzinger Complex (preBötC), mammalian respiratory rhythm generating kernel, is not random, but optimized in course of ontogeny/phylogeny so produces efficiently and robustly. In present study, we attempted to identify synaptic connections among constituent neurons preBötC based on this hypothesis. To do this, first developed an effective evolutionary algorithm for optimizing a neuronal exhibit ‘desired characteristic’. Using algorithm,...

This work is a result of an exploration in response to the following observation: though reconstruction methodology SIM image since its origin carried out frequency domain, recent works this field, specially when it comes using lesser than 9 raw images, have ventured into methodologies that operate directly spatial domain. formulates and demonstrates domain four images – one wide-field three images. One chief feature presented algorithm employs standard 'tools tricks' used by conventional...
