there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...

Let R be an n by n nontrivial real symmetric involution matrix, that is, R R−1 R / In. An n × n complex matrix A is termed R-conjugate if A RAR, where A denotes the conjugate of A. We give necessary and sufficient conditions for the existence of the Hermitian R-conjugate solution to the system of complex matrix equations AX C andXB D and present an expression of the Hermitian R-conjugate soluti...

Spectropholornetrie technique is used to evaluate binding of the vanadium(1U) ion to a water solublecaruc[4] arene molecule in aqueous solution. On the basis of the calculated value formation constant at25rC.we found that the eomplexation of this metal on is very favored towards 25, 26, 27, 2Stetrahydroxy-5, 11, 17, 23-tetnmulphonalic acid-calix[0]areneGaussian 03 package.

A square complex matrix A is called if it can be written in the form EP   1 0 U A U  with U being fixed unitary and 1 A being arbitrary matrix in . We give necessary and sufficient conditions for the existence of the solution to the system of complex matrix equation r r   r EP , AX B XC D   and present an expression of the solution to the system when the solvability conditions are satisf...

Currently, all commercial available nebulized salbutamol in China is in its racemic form. It is known that only R-salbutamol (eutomer) has therapeutic effects, while S-salbutamol (distomer) may exacerbate asthma after chronic use. Therefore, it is an unmet clinical need to develop R-salbutamol as a nebulized product that is more convenient for young and old patients. In our study, a stable aero...
