A Free Variation of Anna Akhmatova's "Lines"

Oxygen consumption during hover-feeding in free-ranging Anna hummingbirds.

Rates of oxygen consumption during hover-feeding of wild, unrestrained, adult male Anna hummingbirds (Calypte anna) were measured with an artificial outdoor feeder converted into a respirometer mask. A computer sampled changes in O2 concentration in air drawn through the mask, automatically detecting the presence of a hummingbird from a drop in the O2 concentration, and photoelectrically timing...

Overlap - Free Symmetric D 0 L words † Anna

It was rediscovered several times, can be constructed in many alternative ways and occurs in various fields of mathematics (see the survey [1]). The set of all overlap-free words was studied e. g. by E. D. Fife [8] who described all binary overlapfree infinite words and P. Séébold [13] who proved that the Thue-Morse word is essentially the only binary overlap-free word which is a fixed point of...

ANNA CONTADINI : A World

Anna M

So far studies on language comprehension adopting the embodied and grounded perspective have underlined the similarities between language and action. In line with the idea of neural re-use, this chapter shows that language reflects some characteristics of action organization, but also that it builds on these characteristics, and modifies them in sophisticated ways. In the first part evidence is...

Variation of Quasiconformal Mappings on Lines

We obtain improved regularity of homeomorphic solutions of the reduced Beltrami equation, as compared to the standard Beltrami equation. Such an improvement is not possible in terms of Hölder or Sobolev regularity; instead, our results concern the generalized variation of restrictions to lines. Specifically, we prove that the restriction to any line segment has finite p-variation for all p > 1 ...
