Current Biology, 2018 How do some insects jump so quickly? As anyone who has tried to catch a grasshopper or a planthopper knows, many insects can jump very rapidly. A planthopper can accelerate in less than 1 millisecond to a take-off velocity of 5 m s–1, requiring a power output (energy per given time) of tens of thousands of Watts per kilogram of muscle.

Sprint performance following plyometric conditioning activity in elite sprinters
Baltic Journal of Health and Physical ActivityIntroduction: Considering the significance of the ankle joint for sprinting with the spring-like properties of the Achilles tendon, it seems that plyometric activating exercises could significantly potentiate maximum velocity sprinting.

Anomalous jumping in a double-well potential [PDF]
, 1999 Noise induced jumping between meta-stable states in a potential depends on the structure of the noise. For an $\alpha$-stable noise, jumping triggered by single extreme events contributes to the transition probability.

A note on the depth-from-defocus mechanism of jumping spiders [PDF]
, 2017 Jumping spiders are capable of estimating the distance to their prey relying only on the information from one of their main eyes. Recently, it has been shown that jumping spiders perform this estimation based on image defocus cues.

Detecting jumps from Lévy jump diffusion processes☆ [PDF]
Journal of Financial Economics, 2008 Abstract Recent asset-pricing models incorporate jump risk through Levy processes in addition to diffusive risk. This paper studies how to detect stochastic arrivals of small and big Levy jumps with new nonparametric tests. The tests allow for robust analysis of their separate characteristics and facilitate better estimation of return dynamics ...

The influence of camouflage and prey type on predatory decisions of jumping spider [PDF]
, 2013 Decisions made by predators during predatory encounters are often based on multiple factors that may influence the outcome of the encounters. For stalking predators their visibility to the prey and the ability of their prey to escape may be important ...

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
