We provide generalisations of two Schwarz-type lemmas — the first a result of Globevnik and the other due to Ransford and White — for holomorphic mappings into the spectral unit ball. The first concerns mappings of the unit disc in C into the spectral unit ball, while the second concerns self-mappings. The aforementioned results apply to holomorphic mappings that map the origin to the origin. W...

scholars concern about colors application in poetic images, because color is considered one of the basic principles in images literary aesthetic field. in contemporary literature, poets portray beauty images by colors and indeed the presence of colors in nazok almalaeke poems is one of the basic rhetorical and expressive principles as other contemporary poets. in nazok almalaeke poems white is ...

Objective(s):There is much evidence indicating that depression is influenced by the levels of neurotransmitters such as dopamine, GABA and adrenaline. The current study we designed to investigate the effect of exposure of pregnant rats to different colors on neurotransmitters level, as indicators of mood disorders in off springs. Materials and Methods:Five groups of pregnant female Wistar rats ...

This paper presents a color demosaicing method applied to the Bayer pattern color filter array (CFA). Reliable estimation of an edge direction, edge-directed asymmetric interpolation, and the use of color samples at immediate neighbors are considered as the key guidelines for smooth and sharp image restoration. Also, special interest is directed to local areas that are rich in high spatial freq...

nima yoshij and badr shaker sayyab are two contemporary renowned poet in iran and iraq which using the concepts of the verious colors could show their own personal and social opinion at their poets. no doubt, personal experiences, litererary life and the political and social environment surrounding of each poet can affect the role of the colors in his poems. similar pretty or horrible incident ...

(Received September 1, 2009) Abstract. For a nontrivial connected graph G, let c : V (G) → N be a vertex coloring of G where adjacent vertices may be colored the same. For a vertex v ∈ V (G), the neighborhood color set NC(v) is the set of colors of the neighbors of v. The coloring c is called a set coloring if NC(u) 6= NC(v) for every pair u, v of adjacent vertices of G. The minimum number of c...

We provide a simple overview of some hypoellipticity results with sharp indices for a class of kinetic equations and we outline a general strategy based on some geometrical properties.
