In next-generation light sources, high-brightness electron beams are used in a free-electron laser configuration to produce for use by scientists and engineers numerous fields of research. High-brightness described such sources as having low transverse longitudinal emittances, high peak currents, slice emittance energy spread. The optimal generation preservation during the acceleration process propagation through photon-producing element is imperative quality performance source. To...
Three identical new WEST Ion Cyclotron Resonance Heating (ICRH) antennas have been designed, assembled then commissioned on plasma from 2013 to 2019.The ICRH system is both load-resilient and compatible with long-pulse operations.The three successfully operated together in 2019 2020.The load resilience capability has demonstrated the antenna feedback controls for phase matching developed.The breakdown detection systems validated protected antennas.The use of combination Lower Hybrid...
Despite recent advances in molecular diagnostics, ultrafast determination of the antibiotic susceptibility phenotype pathogenic microorganisms is still a major challenge vitro diagnostics (IVD) infectious diseases. Raman microspectroscopy has been proposed as means to achieve this goal. Previous studies have shown that phenotyping could be done through analysis microbial cells, either large clusters or down single-cell level case Gram-negative rods. Gram-positive cocci such Staphylococcus...
To obtain introgressed sunflower lines with improved disease resistance, interspecific crosses were performed foreign perennial species. We report on several unusual features displayed by these hybrid plants. The methods used to produce the kernels affected yield and genotypes of progeny. Phenotypic traits DNA markers investigated in 97 plants derived from cross‐pollination between annual diploid cultivated (Helianthus annuus) species H. mollis or orgyalis, reverse reciprocal crosses. level...
We present a new method to achieve autofocus in digital holographic microscopy. The is based on inserting calibrated objects into sample placed slide. Reconstructing hologram using the inverse problems approach makes it possible precisely locate and measure inserted thereby derive slide plane location. Numerical focusing can then be performed at any chosen distance from of reproducible manner independently diversity sample.
A variety of groups like a Fischer carbene complex, an N-hydroxysuccinimide or ferrocene derivative have been grafted by ruthenium-catalyzed cross-metathesis reaction with terminal alkene on monolayer-protected gold clusters as mild and convenient strategy to anchor functional molecules.
In the context of digital in-line holographic microscopy, we describe an unsupervised methodology to estimate aberrations optical microscopy system from a single hologram. The method is based on Inverse Problems Approach reconstructions holograms spherical objects. forward model Lorenz-Mie distorted by described Zernike polynomials. This thus able characterize most varying in field view order take them into account improve reconstruction any sample. We show that this approach increases...
Here, we develop a system where long double-stranded DNAs (ds-DNAs) are immobilized on the surface of polystyrene (PS) microsphere. A simple synthetic strategy is adopted in order to achieve this goal which single DNA chain anchored by one its extremities latex We chose hybridization as unique method attach ds-DNA chains solution with oligonucleotides grafted modified aminated microspheres. The chosen were various sizes and sources: T7A1 (4.48 kilobase pair (kbp)), plasmid DNA; ΔDIIIT7...
In multispectral digital in-line holographic microscopy (DIHM), aberrations of the optical system affect repeatability reconstruction transmittance, phase and morphology objects interest. Here we address this issue first by model fitting calibration using transparent beads inserted in sample. This step estimates as a function lateral position field view at each wavelength. Second, use regularized inverse problem approach (IPA) to reconstruct transmittance Our method accounts for...
In several areas of imaging, it is necessary to detect the weak signal a known pattern superimposed similar or more contrasted patterns. Detecting interest then requires robust detection techniques. case spatially extended patterns, computational complexity systematically evaluating loss function at all possible locations becomes prohibitive. this work, we propose fast algorithm applicable various functions. The proposed approach evaluated on simulated and experimental in-line holograms.
In the context of multi-wavelength in-line holographic microscopy micrometer-sized samples, we propose a 2-step methodology to estimate geometric and chromatic aberrations optical system then use this calibration step better reconstruct complex transmittance at focus. The first uses an aberration-wise Lorenz-Mie model jointly parameters beads spread in sample 14 Zernike coefficients each wavelength. Then, reconstruction is performed using regularized inverse problems approach whole data set...
