Colour and melanopsin mediated responses in the murine retina

open access: yesFrontiers 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 ...

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

open access: yesIEEE 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-

A time for atlases and atlases for time [PDF]

open access: yesFrontiers in Systems Neuroscience, 2010
Advances in neuroanatomy and computational power are leading to the construction of new digital brain atlases. Atlases are rising as indispensable tools for comparing anatomical data as well as being stimulators of new hypotheses and experimental designs. Brain atlases describe nervous systems which are inherently plastic and variable. Thus, the levels

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

open access: yesApplied 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.

Continuous-time games of timing [PDF]

open access: yesJournal of Economic Theory, 2005
Abstract We address the question of existence of equilibrium in general timing games with complete information. Under weak assumptions, any two-player timing game has a Markov subgame perfect e-equilibrium, for each e>0. This result is tight. For some classes of games (symmetric games, games with cumulative payoffs), stronger existence results are ...

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

open access: yesApplied 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.

Circadian clock mechanism driving mammalian photoperiodism

open access: yesNature 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.

Hypothalamic remodeling of thyroid hormone signaling during hibernation in the arctic ground squirrel

open access: yesCommunications Biology, 2022
Arctic ground squirrels hibernating in darkness activate the pars tuberalis - hypothalamus thyroid hormone signaling pathway, remodel hypothalamic tanycytes, and activate the reproductive axis.

Time Discounting and Time Consistency [PDF]

open access: yes, 2012
Time discounting is the phenomenon that a desired result in the future is perceived as less valuable than the same result now. Economic theories can take this psychological fact into account in several ways. In the economic literature the most widely used type of additive time discounting is exponential discounting. In exponential discounting, the fall

From time to times [PDF]

open access: yesFractional Calculus and Applied Analysis, 2022
Abstract We give an overview of the concept of random time changes in evolution processes. First of all, we discuss random times in Markov processes. Secondly, we propose to use the concept of random times for dynamical systems. In both cases did appear fractional evolution equations.
