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. However, there is no scientific evidence to back up these claims. This study was undertaken to measure(More)
An accurate and efficient base resistance (R<sub>B</sub>) extraction methodology for SiGe HBT HICUM model is developed in this paper. Differing from previous methods, the proposed technique is based on the rational function fitting. Two formulas are used to determine the lower and upper limits of R<sub>B</sub>, and then R<sub>B</sub> is confined to a very(More)
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)
An improved high-frequency small-signal model for SiGe HBTs under the off-state is presented in this paper. The proposed model takes into account the distribution characteristics of the intrinsic transistor, link base region under spacer, and extrinsic base-collector junction. The equivalent circuit for each region is separately derived using the(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)
