Multilayer Laue lenses are volume diffractive optical elements for hard X-rays with the potential to focus beams sizes as small 1 nm. This ability is limited by precision of manufacturing process, whereby systematic errors that arise during fabrication contribute wavefront aberrations even after calibration deposition process based on metrology. Such can be compensated using a phase plate. However, current high numerical aperture nanometer resolution exhibit exceed those corrected single To...
Cash flow control is a reference point for the effective activities of business entities, which allows achieving specific effect from and functioning both individual corporate structures large economic systems — industries, regions state as whole. In this regard, in order to form unified approach cash control, it advisable create an system standards regulating these processes. preparation national controlling implementation particular activity becoming very relevant, helps strengthen...
We present experimental data on H2 formation processes gas-phase polycyclic aromatic hydrocarbon (PAH) cations. This process was studied by exposing coronene radical cations, confined in a radio-frequency ion trap, to H atoms. Sequential attachment of up 23 hydrogen atoms has been observed. Exposure atomic D instead allows one distinguish from competing abstraction reactions, as the latter now leave unique fingerprint measured mass spectra. Modelling results using realistic cross-sections...
The Multi-Purpose Detector (MPD) is designed to study a hot and dense baryonic matter formed in heavy-ion collisions at SQRT(sNN)=4-11 GeV the NICA accelerator complex (Dubna, Russia). Large-sized electromagnetic calorimeter (ECal) of MPD spectrometer will provide precise spatial energy measurements for photons electrons central pseudorapidity region |eta|<1.2. Shashlyk-type sampling structure ECal optimized range from about 40 MeV 2-3 GeV. Fine segmentation projective geometry allow deal...
A Multi Purpose Detector (MPD) is being constructed for the Heavy-Ion Collider at Dubna (NICA). One of important components MPD setup an Electromagnetic Calorimeter, which will operate in magnetic field solenoid 0.5 T and provide good energy space resolution to detect particles range from ∼20 MeV few GeV . For this purpose the, so-called, "shashlyk" sampling structure with fiber readout silicon Pixel Avalanche Photodetector used. Serious modifications comparison conventional "shaslyk"...

<title>Abstract</title> High-resolution X-ray imaging of non-crystalline objects is often achieved through the approach scanning coherent diffractive known as ptychography. The resolution usually limited by scattering properties sample, where weak diffraction signals at highest angles compete with background noise and parasitic scattering. Here we demonstrate that multilayer Laue lenses high numerical aperture (NA) can be used to create a strong reference beam holographically boosts from...
A noise-robust sub-10 nanometer imaging resolution from a Siemens star sample was achieved, by ptychographically reconstructing projection holograms recorded at an effective magnification of more than 11,800 in the regime hard X-rays.

In this regard, issue legality effectiveness such structures on part control bodies increasing, responsibility for targeted effective usage relevant funds also increasing view trend expand boundaries at all levels government....
Sub-angstrom spatial resolution of electron density coupled with sub-femtosecond temporal is required to directly observe the dynamics electronic structure a molecule after photoinitiation or some other ultrafast perturbation. Meeting this challenge, pushing field quantum crystallography attosecond timescales, would bring insights into how and nuclear degrees freedom couple, enable study coherences involved in molecular dynamics, ultimately these be controlled. Here we propose reach realm by...
