The structural and functional characteristics of tectospinal neurons in the golden hamster
Journal of Comparative Neurology, 1987AbstractIntracellular recording and horseradish peroxidase (HRP) injection techniques were used to delineate the structural and functional characteristics of the superior collicular cells in the hamster, which could be antidromically activated from the first cervical segment of the spinal cord.

Structure of the Lining Epithelium of the Cauda Epididymis of the Golden Hamster
Anatomia, Histologia, Embryologia, 2009SummaryThe ductus epididymis has roles in the maturation and storage of spermatozoa. The main function of the cauda epididymis is the storage of spermatozoa; however, this region exerts other morphophysiological roles. So, this study was aimed at investigating structural features of the cauda epididymis epithelium, which could indicate roles other than

Electronic golden structure of the periodic chart
Chaos, Solitons & Fractals, 2009Abstract The golden ratio has been studied since the ancient Greeks due to its inherent symmetry and aesthetic beauty, especially in the five Platonic Solids. The golden mean is now established as a pillar of El Naschie’s E infinity where it achieves the physical manifestation of 0.618 034 MeV.

On Kähler–Norden–Codazzi golden structures on pseudo-Riemannian manifolds
International Journal of Geometric Methods in Modern Physics, 2018In this paper, we consider a pseudo-Riemannian manifold equipped with a Kähler–Norden–Codazzi golden structure. For such a manifold, we study curvature properties. Also, we define special connections of the first type and of the second type on the manifold, which preserve the associated twin Norden golden metric and satisfy some special conditions and

On Submanifolds in a Riemannian Manifold with Golden Structure
2018A golden Riemannian structure $(J,g)$ on a Riemannian manifold is given by a tensor field $J$ of type $(1,1)$ satisfying the golden section relation $J^{2}=J+I,$ and a pure Riemannian metric $g$, that is a metric satisfying $g(JX,Y)=g(X,JY).$ We investigate some fundamental properties of the induced structure on submanifolds immersed in golden ...

Golden and Metallic Structures on Hessian Manifolds
We consider the reciprocal cost function $ J(x)=\frac12(x+x^{-1})-1 $ and its $n$-dimensional extension $$J(x_1,\ldots,x_n) = \frac12(R+R^{-1})-1, \qquad R=\prod_{i=1}^n x_i^{α_i}, \qquad α=(α_1,\ldots,α_n)\in\mathbb{R}^n\setminus\{0\}.$$ In logarithmic coordinates $t_i=\log x_i$, the Hessian of $J$ has rank one at every point.Washburn, Jonathan, Zlatanović, Milan

Ideological structuring during the Golden Age
Abstract The 1945–1975 period witnessed the emergence of a ‘social democratic’ consensus around welfare state building. In the Nordic countries and the UK the formation of this consensus proceeded in a relatively smooth way. In the original Six (and especially in France and Italy), instead, the coming together of the Christian democraticopenaire +1 more source
