Differences in kinematics of the support limb depends on specific movement tasks of take-off

open access: yesActa Gymnica, 2016
Background: Many sport activities are a sequence of jumps (running, jumping, hurdling etc.). Each jump flight phase is the result of the execution of the previous support phase.

Frog origins: inferences based on ancestral reconstructions of locomotor performance and anatomy [PDF]

open access: yes, 2016
Frogs are the most species-rich and ecologically diverse group of amphibians and are characterized by a unique body plan including long legs, elongated ilia, and fused caudal vertebrae.

$D$-modules, Bernstein-Sato polynomials and $F$-invariants of direct summands [PDF]

open access: yes, 2016
We study the structure of $D$-modules over a ring $R$ which is a direct summand of a polynomial or a power series ring $S$ with coefficients over a field. We relate properties of $D$-modules over $R$ to $D$-modules over $S$. We show that the localization

The Dual Phases of Massless/Massive Kalb-Ramond Fields [PDF]

open access: yes, 2001
We have developed dualization of ordinary and ``Stueckelberg compensated'' massive phase for the Kalb-Ramond theory. The compensated phase allows to study the interplay between spin jumping and duality.

Conditioning exercises in ski jumping: biomechanical relationship of squat jumps, imitation jumps, and hill jumps [PDF]

open access: yesSports Biomechanics, 2017
As hill jumps are very time-consuming, ski jumping athletes often perform various imitation jumps during training. The performed jumps should be similar to hill jumps, but a direct comparison of the kinetic and kinematic parameters has not been performed yet.
