The existing algorithms for the minimum concave cost network flow problems mainly focus on the single-source problems. To handle both the single-source and the multiple-source problem in the same way, especially the problems with dense arcs, a deterministic annealing algorithm is proposed in this paper. The algorithm is derived from an application of the(More)
Ginger (Zingiber officinale) has been traditionally used to check hair loss and stimulate hair growth in East Asia. Several companies produce shampoo containing an extract of ginger claimed to have anti-hair loss and hair growth promotion properties.

The transition from acute pain to chronic pain entails considerable changes of patients at multiple levels of the nervous system and in psychological states. An accurate differentiation between acute and chronic pain is essential in pain management as it may help optimize analgesic treatments according to the pain state of patients. Given that acute and(More)
In the title compound, {[Cu(C24H15N2O4)2(H2O)2]·4C3H7NO} n , the Cu(II) ion, lying on an inversion center, is six-coordinated by two N atoms from two 4-[6-(4-carb-oxy-phen-yl)-4,4'-bipyridin-2-yl]benzoate (L) ligands, two deprotonated carboxyl-ate O atoms from two other symmetry-related L ligands and two water mol-ecules in a slightly distorted octa-hedral(More)
