use of raman spectroscopy to decrease time for identifying the species of candida growth in cultures
background: the objective of this study is to establish raman signatures from pure cultures of different candida species using raman spectroscopy (rs) and use these signatures for rapid identification of unknown candida species. methods: pure cultures of five candida species were evaluated using rs to build a limited signature library. ‘raman processing’ (rp) software was used for principal com...
In this study, features of neural signal recordings with microelectrode injected into the internal globus pallidus of non-human primates before and after 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP) treatment which induces Parkinson’s disease (PD) were investigated. Neural oscillations were analyzed using the measure of wavelet spectrum and singular value extraction. Differences in th...
In this paper a fast method for large-scale sparse inversion of magnetic data is considered. The L1-norm stabilizer is used to generate models with sharp and distinct interfaces. To deal with the non-linearity introduced by the L1-norm, a model-space iteratively reweighted least squares algorithm is used. The original model matrix is factorized using the Golub-Kahan bidiagonalization that proje...
