Chiral matter and transitions in heterotic string models [PDF]

open access: yes, 1998
In the framework of N=1 supersymmetric string models given by the heterotic string on an elliptic Calabi-Yau $\pi :Z\ra B$ together with a SU(n) bundle we compute the chiral matter content of the massless spectrum.

Maximum entanglement of formation for a two-mode Gaussian state over passive operations [PDF]

open access: yes, 2020
We quantify the maximum amount of entanglement of formation (EoF) that can be achieved by continuous-variable states under passive operations, which we refer to as EoF-potential.

Differential inequalities for spirallike and strongly starlike functions

open access: yesAdvances in Difference Equations, 2021
In this paper, by using a technique of the first-order differential subordination, we find several sufficient conditions for an analytic function p such that p ( 0 ) = 1 $p(0)=1$ to satisfy Re { e i β p ( z ) } > γ $\operatorname{Re}\{ {\mathrm{e ...

Identification of rice blast resistance genes in the rice varieties developed with DNA-markers assistance

open access: yesЗерновое хозяйство России, 2018
Eight rice varieties of the Far East breeding have been studied by the method of DNA-typing to establish the presence of rice blast resistance genes. Six varieties possess one gene each: the varieties ‘Khankaysky 429’ and ‘Khankaysky 52’ possess the gene

Holomorphic Lagrangian subvarieties in holomorphic symplectic manifolds with Lagrangian fibrations and special Kahler geometry

open access: yes, 2021
Let $M$ be a holomorphic symplectic K\"ahler manifold equipped with a Lagrangian fibration $\pi$ with compact fibers. The base of this manifold is equipped with a special K\"ahler structure, that is, a K\"ahler structure $(I, g, \omega)$ and a symplectic

Jak pies z kotem, czyli natura w kreacji nazw blogów o tematyce zwierzęcej

open access: yesRoczniki Humanistyczne, 2023
Nazwy własne reprezentują obszar języka, który – pozostając w ścisłej korelacji z całokształtem ludzkiej kultury – stanowi świadectwo zarówno faktów z przeszłości, jak i obecnej rzeczywistości. Są odzwierciedleniem aktywnej działalności człowieka oraz jego współistnienia i wzajemnych relacji z przyrodą.

Semiclassical Analysis of Spinfoam Model with a Small Barbero-Immirzi Parameter

open access: yes, 2013
We study the semiclassical behavior of Lorentzian Engle-Pereira-Rovelli-Livine (EPRL) spinfoam model, by taking into account of the sum over spins in the large spin regime.

A Tanh Control Method for the Third Mirror’s Z Axis of Large Optical Telescope

open access: yesIEEE Access, 2023
The position accuracy of the third mirror’s Z axis will directly affect the measurement accuracy of the optical telescope, so it is necessary to improve the position accuracy. In order to improve the control performances of the third mirror’
