We consider the algebraic issues concerning the solution of general, large-scale, linearly constrained nonlinear optimization problems. Particular attention is given to suitable methods for solving the linear systems which occur at each iteration of such methods. The main issue addressed is how to ensure that a quadratic model of the objective function is positive definite in the null-space of ...

Microalgae have many biotechnological applications in various industries including food and feed, fertilizer, biofuel, cosmetics, pharmaceutics, wastewater treatment. Since hey produce secondary metabolites under stress conditions such as pigments, carotenoids, hydrocarbons, vitamins, investigating the effects of factors on growth parameters biochemical composition microalgal biomass is needed ...

Rhesus monkeys were trained to criterion on a two-stimulus and a fivestimulus pattern discrimination task. The probabilities of response to the various stimuli throughout learning are examined for individual subjects, and it is fOlL'1d that the subjects exhibit consistency in the order and manner in which incorrect stimuli are eliminated. This suggests a simple mathematical description of the p...

We give a thorough analysis of those subgroups of SO(3) generated by rotations about perpendicular axes by 2π/p and 2π/q. A corollary is that such a group is the free product of the cyclic groups of rotations about the separate axes if and only if p, q ≥ 3 and are both odd. These groups are naturally associated with a family of hierarchical tilings of Euclidean 3-space. Subject Classification: ...

Results The prevalence of various pregnancy complications was 8. 6% for birth prematurely, 9. 2% for hypertension or preeclampsia, IUGR 5. 8% and 7. 3% for loss pregnancy. PAPP A levels were lower in fetal loss group (P = 0. 005), vascular disease group(P = 0. 001) and preterm delivery group(P = 0. 001). In addition, a lower rate of bHCG was associated with the occurrence of placental pathologi...

We report a new measurement of the ratio h/mRb between the Planck constant and the mass of Rb atom. A new value of the fine structure constant is deduced, α = 137.035 999 037 (91) with a relative uncertainty of 6.6 × 10. Using this determination, we obtain a theoretical value of the electron anomaly ae = 0.001 159 652 181 13(84) which is in agreement with the experimental measurement of Gabriel...
