Comparison of coherent and spontaneous Raman microspectroscopies for noninvasive detection of single bacterial endospores.
Single bacterial spores were analyzed by using nonlinear Raman microspectroscopy based on coherent anti-Stokes Raman scattering (CARS). The Raman spectra were retrieved from CARS spectra and found to be in excellent agreement with conventionally collected Raman spectra. The phase retrieval method based on maximum entropy model revealed significant robustness to external noise. The direct compar...
متن کاملImproving sensitivity in nonlinear Raman microspectroscopy imaging and sensing.
Nonlinear Raman microspectroscopy based on a broadband coherent anti-Stokes Raman scattering is an emerging technique for noninvasive, chemically specific, microscopic analysis of tissues and large population of cells and particles. The sensitivity of this imaging is a critical aspect of a number of the proposed biomedical application. It is shown that the incident laser power is the major para...
متن کاملStochastic Optimization of PCA with Capped MSG
We study PCA as a stochastic optimization problem and propose a novel stochastic approximation algorithm which we refer to as “Matrix Stochastic Gradient” (MSG), as well as a practical variant, Capped MSG. We study the method both theoretically and empirically.
متن کاملDWDM Transmission using Hybrid Optical Amplifiers
In this paper the transmission performance of 32 × 10 Gbps with 0.8 nm channel spacing dense wavelength division multiplexed system using hybrid optical amplifiers (RAMAN-EDFA, RAMAN-SOA AND EDFA-SOA) has been investigated. The performance has been compared at different distances and has been evaluated on the basis of Quality factor, optical output power, bit error rate and average eye opening....
متن کاملX-ray radiation effects in multilayer epitaxial graphene
We characterize multilayer graphene grown on C-face SiC before and after exposure to a total ionizing dose (TID) of 12 Mrad(SiO2) using a 10 keV X-ray source. While we observe the partial peeling of the top graphene layer and the appearance of a modest Raman D-peak, we find that the electrical characteristics (mobility, sheet resistivity, free carrier concentration) of the material are mostly u...
