Colour and melanopsin mediated responses in the murine retina

Frontiers in Cellular Neuroscience, 2023
Introduction: Intrinsically photosensitive retinal ganglion cells (ipRGCs) integrate melanopsin and rod/cone-mediated inputs to signal to the brain. Whilst originally identified as a cell type specialised for encoding ambient illumination, several lines ...

Time perception: Brain time or event time? [PDF]

Current Biology, 2001
Recent experiments show that synchronous events can appear to an observer to occur at different times. Neural processing time delays are offered as an explanation of these temporal illusions, but equating perceived time with processing time leads to some thorny philosophical problems.

The Effect of BDS-3 Time Group Delay and Differential Code Bias Corrections on Positioning

Applied Sciences, 2020
The timing group delay parameter (TGD) or differential code bias parameter (DCB) is an important factor that affects the performance of GNSS basic services; therefore, TGD and DCB must be taken seriously.

Numerical Modeling of AC Loss in HTS Coated Conductors and Roebel Cable Using T-A Formulation and Comparison With H Formulation

IEEE Access, 2021
With recent advances in second-generation high temperature superconductors (2G HTS) and cable technologies, various numerical models based on finite-element method (FEM) have been proposed to help interpret measured AC loss and assist cable design. The T-

Effect of Pitch Parameters on Aerodynamic Forces of a Straight-Bladed Vertical Axis Wind Turbine with Inclined Pitch Axes

Applied Sciences, 2021
Pitch regulation plays a significant role in improving power performance and achieving output control in wind turbines. The present study focuses on a novel, pitch-regulated vertical axis wind turbine (VAWT) with inclined pitch axes.

Timely Time Estimates

, 2010
Estimations of execution time are essential for design and development of safety critical embedded real-time systems, such as avionics, automotive and aerospace systems. In such systems, execution time is part of the functional specification, hence correct behaviour requires sufficiently powerful target hardware to meet deadlines or achieve required ...

The importance of meal timing for maintenance of daily rhythms in the gut transcriptome and microbiota

npj Biological Timing and Sleep
Gut function exhibits 24 h (circadian) rhythmicity, in part driven by intrinsic clocks within intestinal epithelial cells (IECs). The gut microbiome also demonstrates circadian rhythms in composition and function, important for maintenance of metabolic ...

Time and the other time: Trajectories of Fiji time [PDF]

History and Anthropology, 2018
This article looks into the valuation of time in Fiji with particular emphasis on ‘Fiji time’, an idiom typically employed in reference to unpunctuality or relaxing.

Age interferes with sensorimotor timing and error correction in the supra-second range

Frontiers in Aging Neuroscience, 2023
IntroductionPrecise motor timing including the ability to adjust movements after changes in the environment is fundamental to many daily activities. Sensorimotor timing in the sub-and supra-second range might rely on at least partially distinct brain ...

Circadian clock mechanism driving mammalian photoperiodism

Nature Communications, 2020
“Life in a seasonal environment requires appropriate timing of physiological changes to survive, but how the circadian clockwork times these changes remains unclear.
