The aim of this paper is to study jumping numbers and multiplier ideals of any ideal in a two-dimensional local ring with a rational singularity. In particular we reveal which information encoded in a multiplier ideal determines the next jumping number. This leads to an algorithm to compute sequentially the jumping numbers and the whole chain of multiplier ideals in any desired range. As a cons...

In ski jumping low body weight development resulted in some serious underweight problems and therefore International Ski Federation (FIS) decided to solve the problem by relating maximum ski length to Body Mass Index (BMI). The present study examined the current relationship between body weight (BMI), ski length and performance (jumping distance) in ski jumping. The computer simulation showed t...

Cases of mimicry provide many of the nature's most convincing examples of natural selection. Here we report evidence for a case of predator mimicry in which metalmark moths in the genus Brenthia mimic jumping spiders, one of their predators. In controlled trials, Brenthia had higher survival rates than other similarly sized moths in the presence of jumping spiders and jumping spiders responded ...

Zug, George R. Anuran Locomotion—Structure and Function, 2: Jumping Performance of Semiaquatic, Terrestrial, and Arboreal Frogs. Smithsonian Contribution to Zoology, number 276, 31 pages, 9 figures, 15 tables, 1978.—Frogs evolved as jumping machines. The earliest recognized anuran fossil possessed a foreshortened body and elongated hindlimbs, primary adaptations for jumping. The majority of ext...

Coalescence-induced jumping of condensate droplets from a superhydrophobic surface with hierarchical micro/nanoscale roughness is quantitatively characterized. Experimental observations show that the condensate droplet jumping is induced by coalescence of multiple droplets of different sizes, and that the coalesced droplet trajectories typically deviate from the surface normal. A depth-from-def...

In the present study, interactions of dopamine receptor agonists and antagonists with water swimming stress (WSS) on naloxone-induced jumping in morphine-dependent mice were examined. Mice were rendered dependent as described in the methods section. The opioid receptor antagonist, naloxone (1 mg/kg), was injected to elicit jumping (as a withdrawal sign). The first group exposed to WSS in the pr...

Small creatures have inherent mobility problems due to their stride limitation and small body size compared to surroundings. Meanwhile, some of them, such as locusts and fleas, have evolved to acquire better mobility by employing saltatorial (jumping) locomotion. In the similar context, the mobility of small-scale robots can be improved by jumping. To date, several small-scale jumping robots ha...
