The unification of gauge coupling constants observed in the extrapolation of the high precision LEP data points to the general validity of the ideas of supersymmetry/supergravity and grand unification. This apparant success also then validates the underlying field theoretic approach at least up to the scaleMGUT ≈ 10 GeV. It is then entirely reasonable that one may extrapolate the grand unified ...

We give a mathematical theory of the wetting phenomenon in the 2D Ising model using the formalism of Gibbs states. We treat the grand canonical and canonical ensembles.

Following hep-th/0305177, we write the boundary state of half S-brane in bosonic string theory as a grand canonical partition function of a unitary matrix model. From this representation, it follows that the annulus amplitude can be written as a grand canonical partition function of a unitary two-matrix model. We also show that the contribution of the exponentially growing couplings to the time...

The impact of a discipline’s research is constrained by its ability to articulate compelling problems. Well-crafted problems are the foundation for mobilizing the effort, resources, and attention essential to scientific progress and broader impact. We argue that Information Systems (IS) scholars, individually and collectively, must develop the practice of articulating and engaging large-scale, ...

We discuss a two scalar doublets model which induces the Higgs mechanism by means of a seesaw mechanism. This model naturally predicts a light Higgs scalar whose mass is suppressed by the grand unification scale. The model predicts an intermediate scale between the electroweak symmetry breaking scale and the grand unification scale at 10 GeV. Below this intermediate energy scale the usual stand...

Requiring that supersymmetric SU(5) and SU(6) grand unifications in the heterotic string theory must have 3 chiral families, adjoint (or higher representation) Higgs fields in the grand unified gauge group, and a non-abelian hidden sector, we construct such string models within the framework of free conformal field theory and asymmetric orbifolds. Within this framework, we construct all such st...

The emerging research area of eParticipation can be characterized as the study of technologyfacilitated citizen participation in (democratic) deliberation and decision-making. Using conventional literature study techniques, we identify 105 articles that are considered to be highly relevant to eParticipation. We develop a definitional schema that suggests different ways of understanding an emerg...

This paper describes a system for detecting and estimating the properties of multiple travel lanes in an urban road network from calibrated video imagery and laser range data acquired by a moving vehicle. The system operates in several stages on multiple processors, fusing detected road markings, obstacles, and curbs into a stable non-parametric estimate of nearby travel lanes. The system incor...
