Arousal State-Dependent Alterations in Neural Activity in the Zebra Finch VTA/SNc
Frontiers in Neuroscience, 2020 Sleep-wake behaviors are important for survival and highly conserved among animal species. A growing body of evidence indicates that the midbrain dopaminergic system is associated with sleep-wake regulation in mammals.

Detecting exotic wakes with hydrodynamic sensors [PDF]
arXiv, 2017 Wake sensing for bioinspired robotic swimmers has been the focus of much investigation owing to its relevance to locomotion control, especially in the context of schooling and target following. Many successful wake sensing strategies have been devised based on models of von Karman-type wakes; however, such wake sensing technologies are invalid in the ...

Sleep pattern disruption of flight attendants operating on the Asia–Pacific route [PDF]
, 2011 Jet lag is a common issue with flight attendants in international flights, as they have to cross several time zones back and forth, while their sleep patterns get disrupted by the legally required rest times between flights, which are normally carried

Decline of long-range temporal correlations in the human brain during sustained wakefulness [PDF]
, 2017 Sleep is crucial for daytime functioning, cognitive performance and general well-being. These aspects of daily life are known to be impaired after extended wake, yet, the underlying neuronal correlates have been difficult to identify.

Wakes in inhomogeneous plasmas [PDF]
Physical Review E, 2014 The Debye shielding of a charge immersed in a flowing plasma is an old classic problem in plasma physics. It has been given renewed attention in the last two decades in view of experiments with complex plasmas, where charged dust particles are often levitated in a region with strong ion flow.

Creativity and its link to epilepsy
Epilepsia Open, EarlyView.Abstract Creative thinking represents one of our highest‐order cognitive processes, involving multiple cortical structures and an intricate interplay between several cortical and subcortical networks. It results in novel ideas that translate to useful products or concepts. The evolutionary purpose of creativity is therefore apparent, as it advances our

Dynamic wake modulation induced by utility-scale wind turbine operation [PDF]
arXiv, 2019 Understanding wind turbine wake mixing and recovery is critical for improving the power generation and structural stability of downwind turbines in a wind farm. In the field, where incoming flow and turbine operation are constantly changing, wake recovery can be significantly influenced by dynamic wake modulation, which has not yet been explored.

Interaction of two high Reynolds number axisymmetric turbulent wakes [PDF]
arXiv, 2021 The interaction between turbulent axisymmetric wakes plays an important role in many industrial applications, notably in the modelling of wind farms. While the non-equilibrium high Reynolds number scalings present in the wake of axisymmetric plates has been shown to modify the averaged streamwise scalings of individual wakes, little attention has been ...

Augmented generation of protein fragments during wakefulness as the molecular cause of sleep: A hypothesis [PDF]
, 2012 Despite extensive understanding of sleep regulation, the molecular-level cause and function of sleep are unknown. I suggest that they originate in individual neurons and stem from increased production of protein fragments during wakefulness.
