On a general Lie group G endowed with sub-Riemannian structure and of local dimension d, we characterize the pointwise multipliers Triebel–Lizorkin spaces Fαp,q for p,q∈(1,∞) α>d/p, those Besov Bαp,q q∈[1,∞], p>d d/p<α<1. When is stratified, extend latter characterization to all p,q∈[1,∞] α>d/p.

the electronic structure, energy band structure and electronic density of 2 sno ceramic in cubicphase have been investigated using first principle full potential-linearized augmented plane wave (fp-lapw)method within density functional theory (dft). local density approximation (lda) and the generalizedgradient approximation (gga), which are based on exchange- correlation energy optimization wer...

the high pressure behavior of the structural and electronic properties of kc1 is studied with use of the density functional pseudopotential method within local-density approximation. atzero pressure, the rocksalt phase is found to be lower in energy than cscl structure. however, we predict a phase transition into csci structure at a pressure of about 1.5 gpa. the calculated ground state propert...

To understand how underwinding and overwinding the DNA helix affects its structure, we simulated 19 independent DNA systems with fixed degrees of twist using molecular dynamics in a system that does not allow writhe. Underwinding DNA induced spontaneous, sequence-dependent base flipping and local denaturation, while overwinding DNA induced the formation of Pauling-like DNA (P-DNA). The winding ...

In this paper, Internal Multiple Model Control (IMMC) based on Robust Clustering Algorithm (RCA) is proposed. The IMMC requires, firstly, the definition of set a of local models each one valid in a given region. Different strategies exist in the literature dealing with the determination of the local models base. However, most of these strategies need a priori knowledge of the system. In order t...

A frequency domain dynamic analysis is needed to obtain the response of structures constructed on a system of base isolators on flexible soil when subjected to earthquake ground motion. In such systems, the lateral stiffness of the base isolators is so small, compared to the structural stiffness, that in an earthquake attack the fundamental vibration mode dominates the response. With this in mi...

     Roads have an important role in plants dispersal on different scales. Various plant species settle on roadsides, but some of them can enter the natural environments and threaten their biodiversity. Worldwide knowledge of roadside flora is necessary for local and global management of natural areas. Accordingly, the roadside flora of Northern Khorasan rangelands was studied along the 600 km ...
