We present new solutions of higher dimensional Einstein's equations with a cosmological constant that localize gravity on branes which are transverse to Ricci-flat manifolds or to homogeneous spaces with topologically non-trivial solutions of gauge field e ...
We extend to all orders in perturbation theory a method to calculate supersymmetry-breaking effects by analytic continuation of the renormalization group into superspace. A central observation is that the renormalized gauge coupling can be extended to a re ...
We discuss the possibility of obtaining the observed pattern of quark masses and mixings as a consequence of radiative corrections, gauge invariance and particle content of the theory. We do not allow any kind of additional symmetry, such as family and dis ...
Despite a large amount of data and numerous theoretical proposals, the microscopic mechanism of ransport in thick-film resistors remains unclear. However, recent low-temperature measurements point toward a possible variable-range-hopping mechanism of trans ...
A specific choice of gauge is shown to imply a decoupling between the tensor and scalar components of gravitational radiation in the context of Brans–Dicke-type theories of gravitation. The comparison of the predictions of these theories with those of gene ...
The one-loop effective potential of the SU(5) model is investigated both in high and low temperature approximation. We find the regions of values of coupling constants and temperatures where the SU(5), the SU(4)×U(1) and the SU(3)×SU(2)×U(1) symmetric stat ...
This paper investigates the use of embedded optical fiber Bragg gratings to measure strain near a stress concentration within a solid structure. Due to the nature of a stress concentration (i.e. the strong non-uniformity of the strain field) the assumption ...
We examine the models with gauge group U(1)(k-1) x Pi(i=1)(k) SU(n(i)), which are obtained from decomposing the supersymmetry breaking model of Affleck, Dine and Seiberg containing an antisymmetric tensor field. We note that all of these models are distinc ...
