An Invitation to Singular Symplectic Geometry [PDF]
, 2017 In this paper we analyze in detail a collection of motivating examples to consider $b^m$-symplectic forms and folded-type symplectic structures. In particular, we provide models in Celestial Mechanics for every $b^m$-symplectic structure.

The Problem of Christ’s Acquired Knowledge
Modern Theology, EarlyView.Abstract Thomas Aquinas is universally applauded for his “courage and perspicacity” in eventually admitting an acquired knowledge in Christ. According to this doctrine, Christ, through the experience of his senses, came to know what he previously did not know.

Motion of Test Bodies in a Quasi-Newtonian Potential. II. Comparison with Experiments
Open Astronomy, 2003 The paper deals with the motion of test bodies in a Quasi-Newtonian potential for which the expressions corresponding to the effects of General Relativity are found. It is impossible to choose the values of parameters of the potential which could be in a

Global regularization method for planar restricted three-body problem [PDF]
Serbian Astronomical Journal, 2015 In this paper, global regularization method for planar restricted three-body problem is purposed by using the transformation z = x+iy = ν cos n(u+iv), where i = √−1, 0 < ν ≤ 1 and n is a positive integer. The method is developed analytically and

Celestial Mechanics, Conformal Structures, and Gravitational Waves
, 2005 The equations of motion for $N$ non-relativistic particles attracting according to Newton's law are shown to correspond to the equations for null geodesics in a $(3N+2)$-dimensional Lorentzian, Ricci-flat, spacetime with a covariantly constant null ...

The Analogia Entis for Reformed Theology: Retrieving Calvin's Implicit Metaphysics
Modern Theology, EarlyView.Abstract The famous controversy between Emil Brunner and Karl Barth which led to Barth's ‘No!’ was driven by disagreements over how to read John Calvin: Barth and Brunner never agreed on whether Calvin had a doctrine of the analogy of being. This article rekindles the debate.

Post-Newtonian celestial mechanics in scalar-tensor cosmology [PDF]
, 2016 Applying the recently developed dynamical perturbation formalism on cosmological background to scalar-tensor theory, we provide a solid theoretical basis and a rigorous justification for phenomenological models of orbital dynamics that are currently used

Plant Biotechnology Journal, EarlyView.ABSTRACT Sea Island cotton (Gossypium barbadense) produces premium‐quality fibres, yet the genetic basis underlying its fibre development remains elusive. Here, we identify two key non‐synonymous single nucleotide polymorphisms (SNPs, G/C and G/A) in the gene Gbar_D13G024080, which encodes the TRANSMEMBRANE PROTEIN 209 (TMEM209). These SNPs resulted in
