Thymosm (Ti) is a 4.9 kDa polypeptide that interacts with G-actin and is thought to be an important mediator in cell proliferation, migration, and differentiation. T4 has been identified as a factor involved in the differentiation of human umbilical vein endothelial cells (HUVECs) cultured on Matrigel. Here we have used various in vitro and in vivo migration assays to demonstrate the role of T1...

since direct experimental evidence is not available, this must be verified through a modeling approach, providedadequate data be available. many statistical methods are used to study the relation between independent anddependent variables.this research was carried out at the western part of jazmurian basin tlocated in the southeast ofiran. in this paperused ten physical characteristics such as ...

INTRODUCTION The chemical shift artifact (CSA) results from temporally undersampling a spatial-spectral distribution along a tilted k-t trajectory. This is illustrated in Fig. 1 for the case of H imaging. Figure 1(a) shows a typical H spatial-spectral distribution, in which the two predominant spectral components are from lipid and water protons. Figure 1(b) shows the k-t space sampling pattern...

We study the long-time evolution of surface gravity waves on deep water excited by a stochastic external force concentrated in moderately small wave numbers. We numerically implemented the primitive Euler equations for the potential flow of an ideal fluid with free surface written in Hamiltonian canonical variables, using the expansion of the Hamiltonian in powers of nonlinearity of terms up to...

in this paper, we establish some new results in ultra bessel sequences and ultra bessel sequences of subspaces. also, we investigate ultra bessel sequences in direct sums of hilbert spaces.specially, we show that {( fi, gi)}∞ i=1 is a an ultra bessel sequencefor hilbert space h ⊕ k if and only if { fi}∞ i=1 and {gi}∞ i=1 are ultrabessel sequences for hilbert spaces h and k, respectively.

Previous attempts to accurately compute critical exponents from Wilson’s momentum shell renormalization prescription suffered from the difficulties posed by the presence of an infinite number of irrelevant couplings. Taking the example of the 1d long-ranged Ising model, we calculate the momentum shell renormalization flow in the plane spanned by the coupling constants (u0, r0) for different val...
