Lessons from Toy-Models for the Dynamics of Loop Quantum Gravity
Symmetry, Integrability and Geometry: Methods and Applications, 2012 We review some approaches to the Hamiltonian dynamics of (loop) quantum gravity, the main issues being the regularization of the Hamiltonian and the continuum limit.

Powers That Be: An Adventure in Metaphysics
Philosophical Investigations, EarlyView.ABSTRACT This paper is an investigation into the increasingly popular trend amongst philosophers on the metaphysics of powers, exemplified by the statement: ‘To be real is to possess a power to affect (or to be affected by) other things’. First, I briefly trace the history of this idea (from the Eleatic dialectic of ancient times to present day quantum

Renaissance Studies, EarlyView.Abstract Pedro de Ayala served as a diplomat for King Ferdinand II of Aragon and Queen Isabella I of Castile at the courts of Henry VII, King of England, and James IV, King of Scots. In July 1498, he wrote a letter, partly in cipher, to report to his king and queen on such matters as Spain's interests in international diplomacy; the characters and ...

Effects of underlying topology on quantum state discrimination
European Physical Journal C: Particles and FieldsIn this work, we show that quantum state discrimination can be modified due to a change in the underlying topology of a system. In particular, we explicitly demonstrate that the quantum state discrimination of systems with underlying discrete topology ...

Spin Foams and Canonical Quantization
Symmetry, Integrability and Geometry: Methods and Applications, 2012 This review is devoted to the analysis of the mutual consistency of the spin foam and canonical loop quantizations in three and four spacetime dimensions.

Noncommutative scalar fields: Quantum symmetries and braided BV quantization [PDF]
Kragujevac Journal of ScienceIt is strongly believed that the fully consistent quantum gravity theory should lead to a quantum spacetime. The continuous description of spacetime in terms of differential manifolds is no longer adequate at the quantum gravity energies.

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

A quantum reduction to spherical symmetry in loop quantum gravity
Physics Letters B, 2015 Based on a recent purely geometric construction of observables for the spatial diffeomorphism constraint, we propose two distinct quantum reductions to spherical symmetry within full 3+1-dimensional loop quantum gravity.

Engineering Reports, Volume 8, Issue 8, August 2026.Our research establishes a hybrid feature selection and ensemble machine learning pipeline for the classification of euthyroid, hyperthyroid, hypothyroid, and subclinical hypo‐ and hyperthyroid disorders. Variance Threshold with Backward Feature Elimination attained nearly 100% accuracy, while SHAP and LIME clarified the significance of features and ...
