The Ultraviolet-visible (UV) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. The electric dipole moments and polarizabilities in the molecular excited electronic states were determined. It was found that the electric dipole moments for the excited states (µ*) and the ground states (µ) of these compounds are equal, and the change in dipole moment i...

at present, faryomad is one of the valleys in mayami county from shahrood city that is situated at the eastern part of semnan province (iran). according to hamdolah mostofi, a historian, this city was the capital of jovein county at 8th hegira century (15th ad century). during ilkhanates dynasty, this city was highly credible for several reasons. name of this city has been implied in historical...

mosque architecture is considered as a potent visual symbol of the islamic architects’ design ability. prayer-hall as the manifestation of equality between the believers and the unity of architectural space has challenged such an ability throughout the history. this study, considering the characteristics of light-openings in the domes of iranian mosques’ prayer-hall, aims to investigate these d...

beyond its quantity, natural light has unique properties used intelligently in iranian historical architecture in order to transfer spiritual concepts. religious buildings are a good context for re-reading of light concept. due to its valuable place in iranian-islamic belief as well as its direct relationship with wisdom and philosophy, the qualitative presence of light in architecture, aimed a...

In this article, we study the semilinear elliptic equation −∆u = |u|p(x)−2u, x ∈ R u ∈ D(R ), where N ≥ 3, p(x) = ( p, x ∈ Ω 2∗, x 6∈ Ω, with 2 < p < 2∗ := 2N/(N − 2), Ω ⊂ RN is a bounded set with nonempty interior. By using the Nehari manifold, we obtain a positive ground state solution.

We study linked loops of string in the presence of bosonic condensates and fermionic zero modes on the strings. We find that the strings necessarily carry a current if the bosons have an AharanovBohm interaction with the string. The fermionic case is analyzed in the context of the standard model where there are lepton and quark zero modes on Z−strings. Here we find that the fermionic ground sta...

The triplet zero-field splitting parameters D of [4n]and [4n + 2]-annulenes are calculated within a n-model. The dependence of D on n and the degree of bond lengths alternation is compared with that of ground state properties like magnetic ring currents. Furthermore it is shown that corannulenes which consist of two concentric perimeters with connecting radial bonds cannot be regarded as macroc...

This paper addresses the task of zero-shot image classification. The key contribution of the proposed approach is to control the semantic embedding of images – one of the main ingredients of zero-shot learning – by formulating it as a metric learning problem. The optimized empirical criterion associates two types of sub-task constraints: metric discriminating capacity and accurate attribute pre...
