The Ka canov method is an iteration method for solving nonlinear problems. In this paper, we apply the Ka canov method to solve the problem of quasi-Newtonian ow obeying the Carreau law. The emphasis of the paper is the derivation of a posteriori error estimate for Ka canov iterates. A numerical example shows the eeciency of the error estimate.

PURPOSE Melatonin synthesis in mammalian retinal photoreceptors is under photic and circadian control and regulated by changes in the activity of arylalkylamine N-acetyltransferase (AANAT). Recent studies have suggested that retinal dopaminergic neurons contain a circadian pacemaker, and dopamine is the neurotransmitter that drives circadian rhythmicity in the mammalian retina. METHODS To inv...

Synchrony, Excitability and Firing Frequency in Neurons Containing Dendritic A-type Potassium Currents Current interpretations of mental processes in neuroscience usually focus on the properties of either single nerve cells or of large networks of neurons. The interplay between the cellular and the network levels remains, however, poorly understood. Based on existing experimental evidence, we s...

The effect of cycloheximide (CHX), a protein synthesis inhibitor, on the regulation of proenkephalin (proENK) and prodynorphin (proDYN) mRNA levels, proto-oncogenes, such as c-fos, 35-kDa fra and c-jun mRNA, and the levels of their products induced by kainic acid (KA) in rat hippocampus was studied. The proENK and proDYN mRNA levels were markedly increased 4 and 8 h after KA (10 mg/kg i.p.) adm...

In many languages, the same particles build quantifier words and serve as connectives, additive and scalar particles, question markers, existential verbs, and so on. Do the roles of each particle form a natural class with a stable semantics? Are the particles aided by additional elements, overt or covert, in fulfilling their varied roles? I propose a unified analysis, according to which the par...

The essence of standard X-bar theory is that structure building is asymmetric in the sense that a complex structure inherits properties from only one of its constituents. There are some structures, however, that are best analyzed as reflecting the properties of all their constituents. This kind of symmetric projection should in principle be allowed within the minimalist program if the union of ...
