The use of lithium fluoride (LiF) crystals and films as imaging detectors for EUV soft-x-ray radiation is discussed. or can generate stable color centers, emitting in the visible spectral range an intense fluorescence from exposed areas. high dynamic response material to received dose atomic scale centers make this detector extremely interesting at a spatial resolution which be much smaller than light wavelength. Experimental results contact microscopy test meshes demonstrate order 400nm....
Ultrashort-pulse, laser-produced plasmas have become very interesting laboratory sources to study spectroscopically due their high densities and temperatures, the laser-induced electromagnetic fields present. Typically, these are of small volume low emissivity. Thus, studying near point source requires advanced experimental techniques. We present a new spectrometer design called focusing with spatial resolution (FSSR-2D) based on spherically bent crystal which provides simultaneous spectral...
The "superficiality" of the Turin Shroud body image is a characteristic frequently described in scientific papers but too often vague terms. Originating from discussion among members Science Group, this paper was compiled thoroughly describing unique characteristics superficiality. This concept superficiality here at fabric, thread and fiber levels. At fabric level, we show importance geometry fabric. very specific distribution color emphasized. Finally, confirm that chemically altered layer...
Anamorphosis is a procedure for drawing an image that appears distorted and indecipherable when seen frontally, the becoming intelligible only from eccentric viewpoint or reflected by properly designed mirror. In this paper we propose journey through figurative art, history, psycho-perception geometry, including mathematical proof regarding position of observation point anamorphoses. Finally, discuss applications anamorphic techniques in encryption, counterterrorism, street art advertising....
The Wei-Norman ordering technique is utilized to present a unified approach the time for SU(2), SU(1,1), and SU(3) coherence-preserving Hamiltonians. It shown that characteristic equations of method can be cast in form generalized Bloch equation an space. laws conservation, linked Casimir invariants algebra, are also directly derived from equations.

Soft X‐ray contact microscopy (SXCM), using a pulsed source, offers the possibility of imaging ultrastructure living biological systems at sub‐100 nm resolution. We have developed table‐top plasma source for this application, generated by large‐volume XeCl laser, achieving good conversion efficiency to ‘water‐window’ X‐rays (hν≈280–530 eV). Optimum conditions SXCM are discussed, including effect pulse duration, target material and resist development time on image images Chlamydomonas...
