Comparative metabolomic and physiological analysis uncovers distinct drought tolerance mechanisms in four rice cultivars

Scientific Reports
Drought stress is a major abiotic challenge threatening global food security by negatively affecting rice morphology, physiology, and biochemistry. This study explored the morpho-physiological and metabolomic responses of four rice cultivars (Giza 179 ...

Essay on Kolmogorov Law of Minus 5 over 3 Viewed with Golden Ratio

Advances in High Energy Physics, 2013
The golden ratio is an astonishing number in high-energy physics, neutrino physics, and cosmology. The Kolmogorov −5/3 law plays a role in describing energy transfer of random data or random functions. The contributions of this essay are in twofold.

Spanning forests and the golden ratio

Discrete Applied Mathematics, 2008
For a graph G, let f_{ij} be the number of spanning rooted forests in which vertex j belongs to a tree rooted at i. In this paper, we show that for a path, the f_{ij}'s can be expressed as the products of Fibonacci numbers; for a cycle, they are products of Fibonacci and Lucas numbers. The {\em doubly stochastic graph matrix} is the matrix F=(f_{ij})/f,

Golden sections of inter-atomic distances as exact ionic radii of atoms [PDF]

, 2009
The Golden ratio which appears in the geometry of a variety of creations in Nature is found to arise right in the Bohr radius of the hydrogen atom due to the opposite charges of the electron and proton.

An SU(5)×A5 golden ratio flavour model

Nuclear Physics B, 2015
In this paper we study an SU(5)×A5 flavour model which exhibits a neutrino mass sum rule and golden ratio mixing in the neutrino sector which is corrected from the charged lepton Yukawa couplings.
