This paper discusses multi-skyrmions on the 3-sphere S 3 with variable radius L using the rational map ansatz. For baryon number B = 3,. .. , 9 this ansatz produces the lowest energy solutions known so far. By considering the geometry of the model we find an approximate analytic formula for the shape function. This provides an insight why skyrmions have a shell-like structure.

With the implementation of India’s new map policy user community is looking towards a transformation in the spatial database (from Everest 1830 ellipsoid, Polyconic projection system to WGS 84 ellipsoid, UTM projection system). To bring them on same platform, problem of existence of different transformation parameters has to be dealt with, since due to unavailability of such data from Survey of...

Objective(s): Cholinergic neurons are important neurons in the Pedunculopontine tegmental nucleus (PPT). In this study, nicotinic receptor of the PPT in central cardiovascular regulation in the anesthetized rat was evaluated. Materials and Methods: Saline, acetylcholine (Ach; doses: 90 and 150 nmol), hexamethonium (Hexa; doses: 100 and 300 nmol) and higher doses of Hexa (300 nmol) + Ach (150 nm...

A filtration satisfying this last property has been constructed by Saito [11], but it is not shown that the filtration terminates, that is F p+1CH(X)Q = 0. A definition has also been proposed by J. P. Murre ([8]), under the assumption that a strong Künneth decomposition of the diagonal exists, but it is not proved to satisfy condition ii) above. In fact proving the existence of such a filtratio...

the balanced scorecard framework with a hierarchical, multilayer, and causal-effect structure can shed light on the growth path and pave the development steps, which in addition to monitoring the financial goals. it also considers and controls the other effective and driving factors. in this study, after reviewing the balanced scorecard, a model was proposed in addition to extract the strategic...

any (continuous) map N → M between stably parallelizable compact n-manifolds, n 6= 1, 2, 3, 7, is realizable in R, i.e. the composition of f with an embedding M ⊂ R is C-approximable by embeddings. It has been long believed that any degree 2 map S → S, obtained by capping off at infinity a time-symmetric (e.g. Shapiro’s) sphere eversion S×I → R, was non-realizable in R. We show that there exist...

scientific communications network is presented in, sociology of science. and we can use steven's evaluative bibliometrics to map it. in citation network approach, scientist's communication behavior is predicted through their citation behavior. in this paper, first, concepts such as sociology of science, scientific community, scientific communications and its kinds are described. two k...

The Azores archipelago is located in the Atlantic Ocean and is composed of nine volcanic islands. S. Miguel, the largest one, is formed by three active, E-W trending, trachytic central volcanoes with caldera (Sete Cidades, Fogo and Furnas). Chains of basaltic cinder cones link those major volcanic structures. An inactive trachytic central volcano (Povoação) and an old basaltic volcanic complex ...

1.1. Connections and derivations. Let S be a scheme, and X smooth and finite type over S throughout. We have the rank-n vector bundle ΩX/S of 1-forms on X over S. We also fix some notation in the case that S is of characteristic p: in this case, we denote by FT the absolute Frobenius map for any scheme T , by X = X×S S the p-twist of X over S, where the map used in the fiber product is FS : S →...
