Quantum Tetrahedra

open access: yes, 2009
We discuss in details the role of Wigner 6j symbol as the basic building block unifying such different fields as state sum models for quantum geometry, topological quantum field theory, statistical lattice models and quantum computing.

The exceptional story of massive IIA supergravity [PDF]

open access: yes, 2016
The framework of exceptional field theory is extended by introducing consistent deformations of its generalised Lie derivative. For the first time, massive type IIA supergravity is reproduced geometrically as a solution of the section constraint.

Psychological Safety Among Interprofessional Pediatric Oncology Teams in Germany: A Nationwide Survey

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Psychological safety (PS) is essential for teamwork, communication, and patient safety in complex healthcare environments. In pediatric oncology, interprofessional collaboration occurs under high emotional and organizational demands. Low PS may increase stress, burnout, and adverse events.

Three-Dimensional Time and One-Dimensional Space: A Basic Reformulation of Physical Reality

open access: yesReports in Advances of Physical Sciences
This paper proposes a radical reformulation of spacetime structure, positing that reality consists basically of one spatial dimension and three temporal dimensions, with our perceived three-dimensional space evolving as a projection from this underlying ...

Kirjandusteoreetilise ühendvälja poole / Unified Theoretical Field Perspectives

open access: yesMethis: Studia Humaniora Estonica, 2013
Estonian cultural studies constitute a rich and promising area of research. This area is uniquely positioned to bring together the vast array of methodological approaches that increasingly have come to define our postmodern mindscape.

Affine Connection Representation of Gauge Fields

open access: yesAdvances in High Energy Physics, 2022
There are two ways to unify gravitational field and gauge field. One is to represent gravitational field as principal bundle connection, and the other is to represent gauge field as affine connection.

A cosmotopological relation for a unified field theory

open access: yes, 2007
I present an argument, based on the topology of the universe, why there are three generations of fermions. The argument implies a preferred unified gauge group of SU(5), but with SO(10) representations of the fermions.

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

The elusive unified field theory?

open access: yesRevista Técnica de la Facultad de Ingeniería, 2011
The proposal that the Einstein field equations (Rµï³ = O) originally conceived solely for the gravitational field in a matter free region of space, actually constitute a possible set of unified field equations is re-examined.

Heterotic E6 GUTs and Partition Functions

open access: yes, 2011
The E6 grand unified theory is an attractive candidate intermediate theory between the standard model and string theory. However, only one E6 grand unified model with three generations and at least one adjoint Higgs field has been derived from string ...
