SSRN Electronic Journal, 2021 Even moderate amounts of zero returns in financial data, associated with stale prices, are heavily detrimental for reliable jump inference. We harness staleness-robust estimators to reappraise the statistical features of jumps in financial markets. We find that jumps are much less frequent and much less contributing to price variation than what found ...

To jump or not to jump: The Bereitschaftspotential required to jump into 192-meter abyss [PDF]
Scientific Reports, 2018 AbstractSelf-initiated voluntary acts, such as pressing a button, are preceded by a negative electrical brain potential, the Bereitschaftspotential (BP), that can be recorded over the human scalp using electroencephalography (EEG). Up to now, the BP required to initiate voluntary acts has only been recorded under well-controlled laboratory conditions ...

Modern Physics Letters A, 2013 We propose an alternative paradigm to the conjectured Miransky scaling potentially underlying the physics describing the transition from the conformally broken to the conformally restored phase when tuning certain parameters such as the number of flavors in gauge theories.

Jumping Locomotion Strategies: From Animals to Bioinspired Robots
Applied Sciences, 2020 Jumping is a locomotion strategy widely evolved in both invertebrates and vertebrates. In addition to terrestrial animals, several aquatic animals are also able to jump in their specific environments. In this paper, the state of the art of jumping robots

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

Structural design and jumping motion planning of the jumping leg inspired by a goat's hindlimb [PDF]
Mechanical Sciences, 2023 At present, research on bionic jumping robots mainly focuses on imitating various jumping animals, such as kangaroos, frogs, or locusts. These bionic objects have good jumping ability.

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

Drop jumping. I. The influence of jumping technique on the biomechanics of jumping
Medicine & Science in Sports & Exercise, 1987 In the literature, drop jumping is advocated as an effective exercise for athletes who prepare themselves for explosive activities. When executing drop jumps, different jumping techniques can be used. In this study, the influence of jumping technique on the biomechanics of jumping is investigated. Ten subjects executed drop jumps from a height of 20 cm
