A recently introduced two-channel confocal microscope with correlated detection promises up to 50% improvement in transverse spatial resolution [Simon, Sergienko, Optics Express 18, 9765 (2010)] via the use of photon correlations. Here we achieve similar results in a different manner, introducing a triple-confocal correlated microscope which exploits the correlations present in optical parametr...
Tetanus is caused by the toxin secreted by Clostridium tetani. Due to the rapid infection with this bacterium, it is so important to investigate the tetanus immunity of people. Therefore, electrochemical biosensors, as one of the most effective tools in this regard, have demanded characteristics such as being fast, simple, cost-effective and portable. However, their detection sensitivity is not...
patients with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (melas) present with recurrent and partially reversible neurological deficits. lesions of melas classically cause a signal change in both the grey and white matter, predominantly in the occipital and parietal lobes. these lesions mimic infarction. here, we reported a case of melas with rare neuroimaging finding...
We present a brief overview of the speech enhancement problem for wide-band noise sources that are not correlated with the speech signal. Our main focus is on the spectral subtraction approach and some of its derivatives in the forms of linear and non-linear minimum mean square error estimators. For the linear case, we review the signal subspace approach, and for the non-linear case, we review ...
