Circular programming problems are a new class of convex optimization problems that include second-order cone programming problems as a special case. Alizadeh and Goldfarb [Math. Program. Ser. A 95 (2003) 3-51] introduced primal-dual path-following algorithms for solving second-order cone programming problems. In this paper, we generalize their work by using the machinery of Euclidean Jordan alg...

up to date, there are four pharmacologically characterized subtypes of muscarinic receptors (m1, m2, m3 and m4). in our study we have investigated muscarinic receptor subtypes in smooth muscle layers of human stomach. isolated preparations of longitudinal and circular muscle layers from human stomach were used. acetylcholine, bethanechol, carbachol, pilocarpine and ahr -602 produced concentrati...

Enantioenriched square-pyramidal oxo- and sulfidorhenium(v) complexes have been prepared and their stereochemistry studied by vibrational circular dichroism (VCD) spectroscopy.

recombinant proteins are tending to be the most favorable vaccine-candidates against botulism. recombinant carboxy-terminal of botulinum neurotoxin serotype e (rbont/e-hcc) has been introduced as an efficient vaccine against botulism type e. in this report, we made an effort to investigate the effect of different ph on protein structure to assess if rbont/e-hcc could be used as a vaccine for or...

This paper reviews the best known techniques using circular dichroism spectroscopy such as conventional circular dichroism (i.e. electronic circular dichroism), magnetic circular dichroisms (magnetic vibrational circular dichroism, x-ray magnetic circular dichroism), fluorescence detected circular dichroism, near-infrared circular dichroism, vibrational circular dichroism, Fourier transform inf...

A magnetization vector M imaging using a transmission x-ray microscope with magnetic circular dichroism ~MCD! contrast is demonstrated. MCD images through a semitransparent, 33-nm-thick Fe film are measured at the Fe L3 edge along three different x-ray propagation directions to determine all three components of the M. The transmission images clearly display the vector nature of complex microstr...

We present an x-ray magnetic circular dichroism XMCD study performed at the R L2 edge in RAl2 and RT2 T=Fe,Co intermetallic compounds. By analyzing the modification of the XMCD spectra as both the rare earth and the alloyed element Al, Fe, or Co are changed in the compound, an extra contribution, XMCDT, has been identified and undoubtedly associated with the R 5d -T 3d hybridization in Fe and C...

in this paper, a multi purpose function is presented for optimum design in circular hydrostatic axial bearings. one or more parameters that are directly or indirectly dependent on given data are optimized. usually in the local optimization methods, it is not possible to optimize several parameters simultaneously. in this research, simultaneous optimization of the power loss and the oil temperat...

this paper is concerned with investigation of vertical impedance function of a surface rigid circular foundation resting on a semi-infinite transversely isotropic alluvium. to this end, the equations of motion in cylindrical coordinate system, which because of axissymmetry are two coupled equations, are converted into one partial differential equation using a method of potential function. the g...
