In this paper we investigate the recently found γ-deformed Maldacena-Nunez background by studying the behavior of different semiclassical string configurations. This background is conjectured to be dual to dipole deformations of N = 1 SYM. We compare our results to those in the pure Maldacena-Nunez background and show that the energies of our string configurations are higher than in the undefor...

As a matter of fact, the estimated loss of the human life caused by the earthquake is a crucial issue. This estimate helped to administrators in planning for the preventive measures or the crisis management after the earthquake. In this article, we represented a new model for measuring the loss of human life utilizing the self-organizing competitive neural networks. In the latest model, the neu...

We derive the general equations of motion for a braneworld containing a (localized) domain wall. Euclideanization gives the geometry for braneworld false vacuum decay. We explicitly derive these instantons and compute the amplitude for false vacuum decay. We also show how to construct a toy ekpyrotic instanton. Finally, we comment on braneworlds with a compact spatial direction and the adS soli...

This is a summary of the work in the author’s recent paper with this title written with Jerome Gauntlett, George Papadopoulos and Paul Townsend, hep-th/97022012. We showed how to construct hyper-Kähler 8metrics in terms of arrangements of three-dimensional hyperplanes in six-dimensional euclidean space. The slopes of the planes define two relatively prime integers (p, q). Under reduction to ten...

We study string theory on the analytically continued β deformed background proposed in hep-th/0509036. This non-static model provides a solvable conformal field theory which describes time-dependent twisted string dynamics. With the mini-superspace approach, we examine disk one-point correlators of D-branes and compute winding string pair production rate. We find that these results are consiste...

Institutions of higher education, both public and private, are among the most important institutions of a country. Several economic factors have forced them to act for improving the cost-effectiveness of their activities and the quality of their products (outputs) is strongly expected. Such issues have led universities to focus on profit-making activities and commercialization like manufacturin...
