Development of crystal optics for Multi-Projection X-ray Imaging for synchrotron and XFEL sources
Valerio Bellucci, Sarlota Birnsteinova, Tokushi Sato +27
X-ray Multi-Projection Imaging (XMPI) is an emerging technology that allows for the acquisition of millions of 3D images per second in samples opaque to visible light. This breakth…
Development towards high-resolution kHz-speed rotation-free volumetric imaging
Eleni Myrto Asimakopoulou, Valerio Bellucci, Sarlota Birnsteinova +19
X-ray multi-projection imaging (XMPI) provides rotation-free 3D movies of optically opaque samples. The absence of rotation enables superior imaging speed and preserves fragile sam…
Universality in Incompressible Active Fluid: Effect of Non-local Shear Stress
Viktor Skultety, Sarlota Birnsteinova, Tomas Lucivjansky +1
Phase transitions in active fluids attracted significant attention within the last decades. Recent results show [L. Chen et al., New J. Phys. 17, 042002 (2015)] that an order-disor…
Passive advection of percolation process: Two-loop approximation
Š. Birnšteinová, M. Hnatič, T. Lučivjanský +2
The paradigmatic model of the directed percolation process is studied near its second order phase transition between an absorbing and an active state. The model is first expressed…
