Signaling cascades transmit information downstream and upstream but unlikely simultaneously
(BioMed Central, 2016-08)
Background: Signal transduction is the process through which cells communicate with the external environment, interpret stimuli and respond to them. This mechanism is controlled by signaling cascades, which play the role ...
Contrasting cascade effects of carnivores on plant fitness: a meta-analysis
(Wiley-blackwellMaldenEUA, 2011)
Postural control during cascade ball juggling: Effects of expertise and base of support
(2016-01-01)
Cascade ball juggling is a complex perceptual motor skill which requires efficient postural stabilization. The aim of this study was to investigate effects of experience (expert and intermediate groups) and foot distance ...
Inverse cascades and resonant triads in rotating and stratified turbulence
(American Institute of Physics, 2017-11)
Kraichnan’s seminal ideas on inverse cascades yielded new tools to study common phenomena in geophysical turbulent flows. In the atmosphere and the oceans, rotation and stratification result in a flow that can be approximated ...
Strategy for stopping failure cascades in interdependent networks
(Elsevier Science, 2018-06)
Interdependencies are ubiquitous throughout the world. Every real-world system interacts with and is dependent on other systems, and this interdependency affects their performance. In particular, interdependencies among ...
Ion cyclotron instability triggered by drifting minor ion species: Cascade effect and exact results
(2004)
On the basis of bi-Maxwellian velocity distribution functions it has been recently shown that the combined effect of heavy ion thermal anisotropy and drift velocity can trigger ion-cyclotron instabilities beyond the ...
Metals in superficial sediments of a cascade multisystem reservoir: contamination and potential ecological risk
(2017-11-01)
Cascade multisystem reservoirs are extremely complex ecosystems that require studies to improve understanding of their dynamics and functioning, including the effects of contamination with metals. In this work, superficial ...
Selective defaunation affects dung beetle communities in continuous Atlantic rainforest
(2013-07-01)
Overhunting has caused severe decline or local extinction in many large-bodied mammals with direct consequences on plant regeneration, yet little is known about indirect impacts of selective defaunation on commensal species. ...

Terahertz GaAs/AlAs quantum-cascade lasers
(American Institute of Physics, 2016-03)
We have realized GaAs/AlAs quantum-cascade lasers operating at 4.75 THz exhibiting more than three times higher wall plug efficiencies than GaAs/Al0.25Ga0.75As lasers with an almost identical design. At the same time, the ...
