Finding optimal BKZ parametrs for NTRU lattice reduction
This article is devoted to selection of optimal parameters for lattice reduction attack against lattice-based cryptosystems that use lattices with low rank sublattices. It illustrates design flaws caused by current approach to buiding these types of cryptosystems. Its relevance and novelty lies in the description ...

Hybrid attack on Learning with Errors (LWE) with sparse secret
In 2007, Howgrave-Graham proposed attack against NTRU cryptosystem, which consists of two parts, combining lattice reduction technique and a combinatorial method called meet-in-the-middle (MiTM). In this article, we apply hybrid attack to the Learning with Errors Problem (LWE) with sparse secret. The LWE problem is considered to be one of the most important ...
System analysis and methodology for developing a software product of a mathematical model of physical processes for the aviation industry
The method of closed chains of discrete symmetries is used to multiply Toda lattices in one and two spatial dimensions. Using the modified Toda equations m0TCand m1TC as an example, it is shown that the combination of the Darboux and Schlesinger transformations leads to closed dressing chains.

Distribution of NQR relaxation times in the rotating frame of reference in micro-sized crystallites
This article presents the results of an experimental study into the effect of powder crystallite size on spin-lattice relaxation times in a rotating frame for 35Cl NQR in potassium chlorate, as well as the nutation interferograms. To obtain the distribution of relaxation times, a multi-exponential decay inversion of the longitudinal component of the nuclear magnetization in a rotating frame was used. The multimodal nature of distributions is explained by the influence of surface irregularities and...

The influence of implantation on the bright-ness of nitrogen-vacancy centers
We investigate the properties of spin states in the electronic ground state of a single nitrogen-vacancy center (NV–) in 13C-enriched diamond. The analysis is based on application of a method that uses a complete set of commuting operators (CSCO). Each state is characterized by a single set of values of CSCO. The properties of the spin states change at the level anti-crossing (LAC). This change leads to an increase in the spin-lattice relaxation rate and to a change in the ODMR spectrum. The...

Investigation of changes in the paramets of thin films structures during ion implantation
... paper were investigated the change of parameters of structures of thin film during ion implantation. Thickness of thin films before and after ion implantation were investigated by X-ray reflectivity. Also, crystal structure, average crystallite size and lattice constant were investigated by X-ray diffraction. The possibility of using ion implantation technique as method of changing grains size in structures was demonstrated.

This problem may be solve by NMR study of quadrupolar nuclear, that is probe of electronic environment of guest atom embedded in a host lattice. The study of evolution of coherences of quadrupolar nuclear with spin S = 3/2 in the presence anisotropy chemical shift is shown that interference terms between time dependent quadrupolar interaction and anisotropy chemical shift are induce dynamic ...
Temperature evolution of crystal structure of multiferroic Tb0.95Bi0.05MnO3
The temperature evolution of crystal structure of multiferroic Tb0.95Bi0.05MnO3 has been studied by powder neutron diffraction in the temperature range 100—450 K. It is shown that the lattice parameters and volume expansion coefficient demonstrate anomalies in the interval 150—250 K. These anomalies could be attributed with a phase separation observed earlier for this compound.
