on the verge of the constitutionalist revolution in iran, the three social forces existing in the socio-political arena were competing with each other and at the same time, struggling with the monarchy to increase their share of power: independent intellectuals, traditional followers of religion, and merchants. this rivalry set the scene for a discursive battle in which, each social force was t...

coregistration of optical and radar imageries is a major pre-processing step in many remote sensing applications including change detection and interferometric processing. specially, the coregistration faced more difficulties in radar imageries due to the high noise level and intense spatial-temporal decorrelation. hence, non-automatic coregistration methods are much more time consuming and ine...

Given a nonlinear infinite resistive network, an operating point can be determined by approximating the network by finite networks obtained by shorting together various infinite sets of nodes, and then taking a limit of the nodal potential functions of the finite networks. Initially, by taking a completion of the node set of the infinite network under a metric given by the resistances, limit po...

in the maximum flow network interdiction problem, an attacker attempts to minimize the maximum flow by interdicting flow on the arcs of network. in this paper, our focus is on the nodal interdiction for network instead of the arc interdiction. two path inequalities for the node-only interdiction problem are represented. it has been proved that the integrality gap of relaxation of the maximum fl...

Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors involved in the transcriptional regulation of key metabolic pathways such as lipid metabolism, adipogenesis, and insulin sensitivity. More recent work implicates all 3 PPAR isotypes (alpha, gamma, and delta, also known as beta or beta/delta) in inflammatory and atherosclerotic pathways. Because these ...

C be the normalization of Γ . Let g = (d− 1)(d− 2) 2 − δ; the genus of C. We identify smooth points of Γ with the corresponding points on C. In particular, if P is a smooth point on Γ then the Weierstrass gap sequence at P is considered with respect to C. A smooth point P ∈ Γ is called an (e − 2)-inflection point if i(Γ, T ;P ) = e ≥ 3 where T is the tangent line to Γ at P (cf. Brieskorn–Knörre...

We show that Dirac points can emerge in photonic crystals possessing mirror symmetry when band gap closes. The mechanism of generating Dirac points is discussed in a two-dimensional photonic square lattice, in which four Dirac points split out naturally after the touching of two bands with different parity. The emergence of such nodal points, characterized by vortex structure in momentum space,...

RATIONALE Human embryonic stem cell-derived cardiomyocytes (hESC-CMs) exhibit either a "working" chamber or a nodal-like phenotype. To generate optimal hESC-CM preparations for eventual clinical application in cell-based therapies, we will need to control their differentiation into these specialized cardiac subtypes. OBJECTIVE To demonstrate intact neuregulin (NRG)-1β/ErbB signaling in hESC-C...
