Electrochemical behavior of the new mono and dinuclear Co (III)  complexes of  the types trans-[pyCo((DO)(DOH)pn )(L)]PF6   and [{py Co((DO)(DOH)pn)}2 (μ-dicyd)] (PF6)2   have been studied in acetonitrile solution.  All the  mono nuclear complexes  show two quasi- reversible reduction couples associate  to Co(III/II)an...

We show that a vapor of multilevel atoms driven by far-off-resonant laser beams, with the possibility of interference of two Raman resonances, is highly efficient for creating parity-time symmetric profiles of the probe-field refractive index, whose real part is symmetric and imaginary part is antisymmetric in space. The spatial modulation of the probe-field susceptibility is achieved by a prop...

Based on the bending experiment for two-span continuous post-tension beams with unbounded tendons and externally applied CFRP sheets, the analysis of the stress increment of unbonded tendons is monitored in the loading process. Since self-compacting concrete (SCC) is a suitable innovation,, understanding the implementation of this type of concrete on the ultimate unbonded tendon stress is criti...

Asymmetrically cut perfect crystals, in both the Laue and Bragg geometries, are examined as single crystal monochromators for x-ray beams that are collimated to a small fraction of the Darwin width, as is typical in experiments with coherent x rays. Both the Laue and asymmetric Bragg geometries are plagued by an inherent chromatic aberration that increases the beam divergence much beyond that o...

Basic properties of von Neumann entropy around the strong subadditivity (SSA) are studied for the CAR systems. An entropy inequality named MONO-SSA equivalent to SSA for the tensor-product systems can fail for the CAR systems. However, if the state of the CAR systems is even, MONO-SSA is shown to be equivalent to SSA due to the symmetric purification, and is valid for such a state. Mailing addr...
