The purpose of this research is to provide a deeper understanding of the planar high- symmetry configuration instability. In the ideal case, the distortion corresponds to the movements of nuclei along normal modes that belong to non-totally symmetric irreps of the high symmertry (HS) point group of molecule. The analysis of the structural distortion from the HS nuclear arrangements of the JT ac...

The local, covariant, continuous, anticommuting and nilpotent Becchi-Rouet-Stora-Tyutin (BRST) and anti-BRST symmetry transformations for all the fields of a (0 + 1)-dimensional spinning relativistic particle are obtained in the framework of augmented superfield approach to BRST formalism. The trajectory of this super-particle is parametrized by a monotonically increasing parameter τ that is em...

Variations in the projection of objects on a 2D image , e.g., due to occlusion and articulation, lead to edge maps which are noisy, contain gaps and spurious elements, and which are deformed. These variations in turn cause variations in the edge map which are typically regularized by the use of a salient measure for each edge element. The use of edge salience, however, typically faced with two ...

We study the rise of exceptional points degeneracy (EPD) in various distinct circuit configurations such as gyrator-based coupled resonators, resonators with PT-symmetry, and a single resonator time-varying component. In particular, we analyze their high sensitivity to changes resistance, capacitance, inductance show resonance frequency perturbations. also investigate stability instability cond...

we introduce a new solution for kawahara-kdv equations. the lie group analysis is used to carry out the integration of this equations. the similarity reductions and exact solutions are obtained based on the optimal system method.

It is argued that the problems of the cosmological constant, stability and renormalizability of quantum gravity can be solved if the space-time manifold is not fundamental, but arises through spontaneous symmetry breaking. A “pre-manifold” model is presented in which many points are connected by random bonds. A set of D real numbers is assigned to each point. These numbers are coupled between p...

There are two methods to calculate nucleon decay matrix elements using lattice QCD. One is the direct calculation of the matrix elements dealing with threeand various two-point functions [1,2,3]. The other is the indirect method where one relies on chiral perturbation theory whose low energy constants are calculated on the lattice [4,5,1,2,3]. The former method is preferable but requires huge c...

We present a six-dimensional Higgsless Standard Model with a realistic gauge sector. The model uses only the Standard Model gauge group SU(2)L × U(1)Y with the gauge bosons propagating in flat extra dimensions compactified on a rectangle. The electroweak symmetry is broken by boundary conditions, and the correct splitting between the W and Z gauge boson masses can be arranged by suitable choice...
