We study the transition widths of $\Upsilon(10753)$ and $\Upsilon(11020)$ into standard bottomonium under hypothesis that they correspond to two lowest laying $1^{--}$ hybrid states. employ weakly coupled potential NRQCD an effective filed theory incorporating heavy quark multipole expansions. consider transitions generated by leading order next-to-leading singlet-octet operators. In expansion ...

This article proposes a method to diminish the pose (position plus attitude) drift experienced by an SVO (Semi-Direct Visual Odometry) based visual navigation system installed onboard UAV (Unmanned Air Vehicle) supplementing its estimation non linear optimizations with priors on outputs of GNSS (Global Navigation Satellite System) Denied inertial system. The is inspired in PI (Proportional Inte...

We show a superconvergence property for the Semi-Lagrangian Discontinuous Galerkin scheme of arbitrary degree in the case of constant linear advection equation with periodic boundary conditions.

In this paper, we establish the existence and boundedness of solutions of a doubly nonlinear parabolic system. We also obtain the existence of a global attractor and the regularity property for this attractor in [L(Ω)] and 2 ∏ i=1 B 1+σi,pi ∞ (Ω).

In 1908 Schoenflies characterized a continuous curve (in the plane) by means of its complement. In view of more recent work, the kernel of his characterization may be stated as follows : In order that a plane, bounded, cyclic continuum be a continuous curve it is necessary and sufficient that (1) each of its complementary domains be simple and (2) the collection of its complementary domains be ...

In this paper, we further investigate the constructions of fuzzy connectives on a complete lattice. We firstly illustrate the concepts of left (right) semi-uninorms and implications satisfying the order property by means of some examples. Then we give out the formulas for calculating the upper and lower approximation implications, which satisfy the order property, of a binary operation.

We study semi-stable degenerations of toric varieties determined by certain partitions of their moment polytopes. Analyzing their defining equations we prove a property of uniqueness.

In this paper we deal with the problem of computing Lyapunov functions for stability verification of differential systems. We concern on symbolic methods and start the discussion with a classical quantifier elimination model for computing Lyapunov functions in a given polynomial form, especially in quadratic forms. Then we propose a new semi-algebraic method by making advantage of the local pro...
