Towards a Unified Theory of Health-Disease: I. Health as a complex model-object

Revista de Saúde Pública, 2013
Theory building is one of the most crucial challenges faced by basic, clinical and population research, which form the scientific foundations of health practices in contemporary societies.

Family Unification on an Orbifold

, 2004
We construct a family-unified model on a Z_2xZ_2 orbifold in five dimensions. The model is based on a supersymmetric SU(7) gauge theory. The gauge group is broken by orbifold boundary conditions to a product of grand unified SU(5) and SU(2)xU(1) flavor ...

A Field Theory with Curvature and Anticurvature

Advances in High Energy Physics, 2014
The present work is an attempt to construct a unified field theory in a space with curvature and anticurvature, the PAP-space. The theory is derived from an action principle and a Lagrangian density using a symmetric linear parameterized connection ...

Unification of the standard model and dark matter sectors in [SU(5) × U(1)]4

Journal of High Energy Physics, 2019
A simple model of dark matter contains a light Dirac field charged under a hidden U(1) gauge symmetry. When a chiral matter content in a strong dynamics satisfies the t’Hooft anomaly matching condition, a massless baryon is a natural candidate of the ...

Quantum deSitter cosmology and phantom matter

, 2003
We consider deSitter universe and Nariai universe induced by quantum CFT with classical phantom matter and perfect fluid. The model represents the combination of trace-anomaly driven inflation and phantom driven deSitter universe.

APPLICATION OF ATTACHEMENT THEORY TO EQUINE-FACILITATED THERAPY

Society Register, 2017
Over the past two decades there has been a growing body of evidence, clinical and anecdotal, that equine-facilitated therapy (EFT) is a powerful tool for social workers and mental health clinicians.

Field Equations and Equations of Motion in Post-Newtonian Approximation of the Projective Unified Field Theory

, 2012
The equations of motion of $N$ gravitationally bound bodies are derived from the field equations of Projective Unified Field Theory. The Newtonian and the post-Newtonian approximations of the field equations and of the equations of motion of this system ...

A unified quantum theory I: gravity interacting with a Yang-Mills field

, 2013
Using the results and techniques of a previous paper where we proved the quantization of gravity we extend the former result by adding a Yang-Mills functional and a Higgs term to the Einstein-Hilbert action.Comment: v4: minor corrections in some formulas,

Unified Field Theory

Journal of Applied Mathematics and Physics, 2016
In the Einstein field equations, the geometry or the curvature of space-time defined as depended on the distribution of mass and energy principally resides on the left-hand side is set identical to a non-geometrical tensorial representation of matter on the right-hand side.

Unified model of loop quantum gravity and matter

, 2004
We reconsider the unified model of gravitation and Yang--Mills interactions proposed by Chakraborty and Peld\'an, in the light of recent formal developments in loop quantum gravity.
