Hypercaloric diets have been successfully used as experimental models of obesity. This work compared morphological characteristics of inferior gastrointestinal organs. The experiment lasted 10 weeks, during which the rats' food consumption, body weight, distance between the mouth and neck, distance between mouth and neck, distance between neck and tail, and abdominal circumference were evaluate...

allometric growth pattern and body shape changes of the green terror (andinoacara rivulatus)(cichlidae) were studied using landmark-based geometric morphometric (gm) and traditional methods, from hatching up to 1266 hours post hatching (hph) under culture conditions. the left side of specimens were photographed using digital camera and morphometric characters, including total length, head lengt...

Chains of magnetic impurities placed on a superconducting substrate and forming helical spin order provide a promising venue for realizing a topological superconducting phase. An effective tight-binding description of such helical Shiba chains involves long-range (power-law) hopping and pairing amplitudes which induce an unconventional topological critical point. At the critical point, we find ...

It is well-known that parameter estimates and forecasts are sensitive to assumptions about the tail behavior of the error distribution. In this paper we develop an approach to sequential inference that also simultaneously estimates the tail of the accompanying error distribution. Our simulation-based approach models errors with a tν-distribution and, as new data arrives, we sequentially compute...

Because maturing oocytes and early embryos lack appreciable transcription, posttranscriptional regulatory processes control their development. To better understand this control, we profiled translational efficiencies and poly(A)-tail lengths throughout Drosophila oocyte maturation and early embryonic development. The correspondence between translational-efficiency changes and tail-length change...

The outermost tail feathers in male barn swallows {Hirundo rustica) are the target of a strong directional female mate preference. The" tait ornament is also expressed in females, since females have considerably longer tails than juveniles, either due to (1) a strong genetic correlation between the characters in the two sexes, or (2) direct sexual selection on females. To discriminate between t...
