Cold spell en route delays spring arrival and decreases apparent survival in a long-distance migratory songbird

open access: yesBMC Ecology, 2017
Background Adjusting the timing of annual events to gradual changes in environmental conditions is necessary for population viability. However, adaptations to weather extremes are poorly documented in migratory species.

Interacting Roles of Breeding Geography and Early-Life Settlement in Godwit Migration Timing

open access: yesFrontiers in Ecology and Evolution, 2020
While avian migration timing is clearly influenced by both breeding and non-breeding geography, it is challenging to identify the relative and interdependent roles of endogenous programs, early-life experience, and carry-over effects in the development ...

Timing of sleep and its relationship with the endogenous melatonin rhythm

open access: yesFrontiers in Neurology, 2010
While much research has investigated the effects of exogenous melatonin on sleep, less is known about the relationship between the timing of the endogenous melatonin rhythm and the sleep-wake cycle.

Endogenous timing in duopolies

open access: yes, 2021
Tesis para optar al grado de Doctor en Sistemas de Ingeniería ; In this thesis we aim to understand how does leadership emerge in duopolistic competitions. In particular, we want to know which are the key features, of the firms and the market, that explain that some interactions are simultaneous while others are sequential.

Endogenous Timing in a Price-Setting Mixed Duopoly with a Foreign Competitor [PDF]

open access: yesInternational Journal of Management, Accounting and Economics, 2016
This paper considers mixed duopoly games where a state-owned public firm and a foreign private firm compete in price. The public firm aims to maximize the un-weighted sum of consumer surplus and its own profit. The paper examines a desirable role (either

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Endogenous Timing of Moves in Bertrand-Edgeworth Triopolies [PDF]

open access: yes, 2012
We determine the endogenous order of moves in which the firms set their prices in the framework of a capacity-constrained Bertrand-Edgeworth triopoly. A three-period timing game that determines the period in which the firms announce their prices precedes

Rif1 Binding and Control of Chromosome-Internal DNA Replication Origins Is Limited by Telomere Sequestration

open access: yesCell Reports, 2018
Summary: The Saccharomyces cerevisiae telomere-binding protein Rif1 plays an evolutionarily conserved role in control of DNA replication timing by promoting PP1-dependent dephosphorylation of replication initiation factors.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...
