Wide-aperture Faraday Cup for the High-Intensity Linear Proton Accelerator of the Project DARIA Open
One of the main problems for beam diagnostics in the projected linear proton accelerator for the DARIA compact neutron source is the high pulse and average beam power combined with a relatively low energy, that significantly limits the cho…

Identification of paramagnetic centers of gadolinium and iron in scandium and yttrium orthosilicates Open
The study of grown Sc 2 SiO 5 : Gd and Sc 2 SiO 5 : Fe crystals was carried out by the paramagnetic resonance method. It has been established that Fe 3+ ions replace Sc 3+ in both crystallographic positions, while Gd 3+ ions exhibit a sing…

Optimization in complex spaces with the Mixed Newton Method Open
We propose a second-order method for unconditional minimization of functions $f(z)$ of complex arguments. We call it the Mixed Newton Method due to the use of the mixed Wirtinger derivative $\frac{\partial^2f}{\partial\bar z\partial z}$ fo…

Adaptive Algorithms for Relatively Lipschitz Continuous Convex Optimization Problems Open
Recently there were proposed some innovative convex optimization concepts, namely, relative smoothness [1] and relative strong convexity [2,3]. These approaches have significantly expanded the class of applicability of gradient-type method…
