Slowly evolving dopaminergic activity modulates the moment-to-moment probability of reward-related self-timed movements

open access: yeseLife, 2021
Clues from human movement disorders have long suggested that the neurotransmitter dopamine plays a role in motor control, but how the endogenous dopaminergic system influences movement is unknown.

Finding Nemo’s clock reveals switch from nocturnal to diurnal activity

open access: yesScientific Reports, 2021
Timing mechanisms play a key role in the biology of coral reef fish. Typically, fish larvae leave their reef after hatching, stay for a period in the open ocean before returning to the reef for settlement.

Regulation of Flowering Time by Environmental Factors in Plants

open access: yesPlants, 2023
The timing of floral transition is determined by both endogenous molecular pathways and external environmental conditions. Among these environmental conditions, photoperiod acts as a cue to regulate the timing of flowering in response to seasonal changes.

Price Competition and Setup Cost

open access: yesMathematics, 2021
Few studies analyze the endogenous emergence of price competition in a new product market. This paper analyzes two differentiated products, an existing product and a newly introduced substitutable product, and investigates conditions under which a price ...

Genomic architecture of migration timing in a long-distance migratory songbird

open access: yesScientific Reports, 2023
The impact of climate change on spring phenology poses risks to migratory birds, as migration timing is controlled predominantly by endogenous mechanisms.

Method to determine whether sleep phenotypes are driven by endogenous circadian rhythms or environmental light by combining longitudinal data and personalised mathematical models.

open access: yesPLoS Computational Biology, 2023
Sleep timing varies between individuals and can be altered in mental and physical health conditions. Sleep and circadian sleep phenotypes, including circadian rhythm sleep-wake disorders, may be driven by endogenous physiological processes, exogeneous ...

Endogenous Time Preference and Endogenous Growth [PDF]

open access: yesInternational Economic Journal, 1994
The present paper develops a one-sector aggregate endogenous growth model with intertemporal preference dependence. The resultant model possesses the fundamental property of growth convergence, in the sense that countries with identical parameters regarding technology, preference, and government policy will converge to a steady state with the same ...

Endogenous timing in a vertically differentiated mixed duopoly with Cournot competition

open access: yesArchives of Control Sciences, 2016
This paper compares the equilibrium outcomes under simultaneous and sequential output setting in a mixed duopoly in a vertically differentiated market. When the timing of the output game is determined endogenously, it is shown that simultaneous play in ...

Endogenous Timing with Free Entry [PDF]

open access: yesSSRN Electronic Journal, 2006
A free entry model with linear costs is considered where firms first choose their entry time and then compete in the market according to the resulting timing decisions. Multiple equilibria arise allowing for infinitely many industry output configurations encompassing one limit-output dominant firm and the Cournot equilibrium with free entry as extreme ...
