Directed Acyclic Graphs (DAGs) are directed graphs in which there is no path from a vertex to itself. DAGs an omnipresent data structure computer science and the problem of counting given number vertices has been solved 70’s by Robinson. In many applications one needs construct connected control their edges, but adaptation Robinson’s enumeration take this into account led formulas based on incl...

Abstract The Generalized Uncertainty Principle (GUP) has been discussed in the thick braneworld scenario. By considering Rydberg atoms this background, we show that spacetime geometry affects Maxwell equations inducing an effective dielectric constant on space. In its turn, corrected Coulomb potential by gravitational interaction yields a deviation 3-dimensional Bohr radius. Then, compute corre...

Pleomorphism in cultures of Azotobacter vinelandii was induced by addition of Difco peptone to the growth medium. Under the conditions of the study, 5% peptone gave rise to transient forms described as "fungoid cells" which were osmotically fragile. After some 48 hr of culture, they became osmotically stable and resumed a more typical morphology. It was shown that the pleomorphism-inducing prin...

An optical switch structure which combines a planar lightwave circuit and liquid crystal is proposed and experimentally demonstrated. The switching is realized by inducing total internal reflection through controlling the refractive index of the liquid crystal. The principle and the design of the integrated optical switch are described. Experimental results suggest that anchoring of the liquid ...

In this paper we prove that if $X $ is a Banach space, then for every lower semi-continuous bounded below function $f, $ there exists a $left(varphi_1, varphi_2right)$-convex function $g, $ with arbitrarily small norm,  such that $f + g $ attains its strong minimum on $X. $ This result extends some of the  well-known varitional principles as that of Ekeland [On the variational principle,  J. Ma...

This paper aims to seek approaches in investigating the relationships within emotion words under linguistic aspect, rather than figuring out new algorithms or so in processing emotion detection. It is noted that emotion words could be categorized into two groups: emotion-inducing words and emotion-describing words, and emotion-inducing words would be able to trigger emotions expressed via emoti...

Inductive interactions play a major role in the diversification of cell types during vertebrate development. These interactions have been extensively studied in amphibian embryos (usually Xenopus laevis) where the earliest is mesoderm induction, in which an equatorial mesodermal rudiment is induced from the animal hemisphere under the influence of signal from the vegetal hemisphere. The molecul...

Adenosine triphosphate (ATP) is now established as a principle vaso-active mediator in the vasculature. Its actions on arteries are complex, and are mediated by the P2X and P2Y receptor families. It is generally accepted that ATP induces a bi-phasic response in arteries, inducing contraction via the P2X and P2Y receptors on the smooth muscle cells, and vasodilation via the actions of P2Y recept...

SINCE the discovery by Bautzmann, Holtfreter, Spemann & Mangold (1932) that a diffusion of inducing substance takes place from the inductor into the competent reacting tissue, protein and ribonucleic acid have been favoured by candidates for the study of the nature of the inducing substance (see Brachet, 1960a, b). Recently Mangold, Tiedemann & Woellwarth (1956) studied the inductive capacity o...
