Holographic Approach

In the usual holographic approach to QCD, the meson spectrum is generated due to a nontrivial five-dimensional background. We propose an alternative five-dimensional scenario in which the spectrum emerges due to coupling to a scalar field whose condensation is supposed to be dual to the formation of gluon condensate and mimics the scale anomaly in QCD. The spectrum of model has finite number of discrete states plus continuum and reveals a Regge-like behavior in the strong coupling regime.

Two novel sample preparation procedures have been developed to visualize morphological structures in embryonic and fetal tissues. In the first, optimization of the sample preparation allows for the visualization of embryos with a thickness in excess of 500 microns. The morphology of the internal structures in these embryos is observed by optical sectioning. The general sample preparation procedures included paraformaldehyde fixation, methanol dehydration and clearing with either benzyl alcohol/benzyl benzoate or methyl salicylate. The dyes (i.e. LysoTracker Red, YoPro) are incorporated into living or fixed embryos to indicate a specific biological function or embryo morphology. Using these stained embryos, the detection of apoptosis and its subsequent quantification were made in addition to the observation of morphology.In the second technique, the confocal microscope has been adapted to produce images similar to those generated by a scanning electron microscope. For this application, the embryos are coated with a dilute solution of acridine orange resulting in opaque surface fluorescence.

Holographic Approach

For magnetic flux mapping in magnetic materials it is important to use a simple, reliable and quantitative method operating with resolution down to few nanometers scale. The traditional off-axes electron holography can reach, in principle, such a resolution. However, the time-consuming phase reconstruction procedure limits its applications to real-time dynamic studies of magnetic domains behavior under varied external field. A novel recently developed in-line holographic approach, based on magnetic interferograms generated by phase-coherent Foucault (PCF)-imaging, complies with most of these demands and is suitable for dynamic studies of domain structure. For instance, it was successfully applied for induction mapping of closure domains in soft Fe-films [1]. It was found, however, that the resolution of PCF-imaging was lower than that of off-axis electron holography, since it is limited by the observed fringe spacing [2].We report that the real resolution of PCF-imaging can be improved significantly with help of a novel phase amplification method.
