Elliptic quantum groups can be associated to solutions of the star-triangle relation of statistical mechanics. In this paper, we consider the particular case of the Eτ,η(so3) elliptic quantum group. In the context of algebraic Bethe ansatz, we construct the corresponding Bethe creation operator for the transfer matrix defined in an arbitrary representation of Eτ,η(so3).

We give a classification of 3-family SO(10) and E6 grand unification in string theory within the framework of conformal field theory and asymmetric orbifolds. We argue that the construction of such models in heterotic string theory requires certain Z6 asymmetric orbifolds that include a Z3 outerautomorphism, the latter yielding a level-3 current algebra for the grand unification gauge group SO(...

We examine the in uence of gauge kinetic mixing on the couplings of a TeV scale Z 0 in both E6 and SO(10) models. The strength of such mixing, which arises due to the existence of incomplete matter representations at low scale, can be described by a single parameter, . The value of this parameter can signi cantly in uence the ability of both hadron and lepton colliders to detect a Z 0 using con...

We examine the influence of gauge kinetic mixing on the couplings of a TeV scale Z ′ in both E6 and SO(10) models. The strength of such mixing, which arises due to the existence of incomplete matter representations at low scale, can be described by a single parameter, δ. The value of this parameter can significantly influence the ability of both hadron and lepton colliders to detect a Z ′ using...

A Z2 orbifold compactification of the heterotic string is considered. The resulting 6D GUT groups can be SO(16) or E7 × SU(2) plus some hidden sector groups. The N = 4 supersymmetry is reduced to N = 2. In particular, the SO(16) 6D model with one spinor representation 128 can reduce to the previous 5D SO(16) or SO(14) family unification models after compactifying the sixth dimension. To obtain ...

Stem cells are cells with the ability to divide for indefinite periods and to give rise to specialized cells.  Stem cell therapy has now been emerged as an extraordinary promise to treat a wide range of diseases and conditions.  However, except blood stem cell transfer by bone marrow transplant which has been used as an standard practice for more than 50 years, nearly all of therapeutic potenti...

neurological development is largely a result of the learning that takes place starting at birth and during the earliest years of life. child care and preschool education programs are key to predicting ultimate success in school and life. children who attend preschool or other early education programs have enhanced cognitive, verbal, and social development (which is maintained into the first few...
