Does hatch date set the clock? Timing of post‐fledging movements for families of a colonially breeding, long‐distance migratory songbird

open access: yesJournal of Avian Biology, 2022
Factors that influence the development of migration timing in juvenile songbirds have implications for the ability of individuals to respond positively to rapid environmental changes.

Advances in research on relationship of circadian disruption with cardiac dysfunction [PDF]

open access: yesJichu yixue yu linchuang, 2022
Accumulating evidence has shown that disruption of the circadian timing system by either endogenous genetic variants or exogenous environmental factors is significantly associated with increased risk of cardiovascular diseases, such as myocardial ...

Overconfidence and Timing of Entry

open access: yesGames, 2020
We analyze the impact of overconfidence on the timing of entry in markets, profits, and welfare using an extension of the quantity commitment game. Players have private information about costs, one player is overconfident, and the other one rational.

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 Timing in Mixed Duopoly with Wage-Rise Contracts as Strategic Device [PDF]

open access: yesInternational Journal of Management, Accounting and Economics, 2020
This paper considers a mixed duopoly market in which a private firm competes against a public firm. Each firm first has to choose the timing for offering a wage-rise contract as a strategic device. The timing of the game is as follows. In stage one, each
