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 the presence of non‐monotonicities

open access: yesCanadian Journal of Economics/Revue canadienne d'économique, 2020
AbstractThe aim of this paper is to generalize the endogenous timing game proposed by Hamilton and Slutsky (Games and Economic Behavior, 1990, 2, pp. 29–46) by allowing the payoff or the marginal payoff of a player to become non‐monotonic with respect to the strategy of the opponent. We propose a taxonomy of the subgame‐perfect Nash equilibria based on

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

Anthropoid primate-specific retroviral element THE1B controls expression of CRH in placenta and alters gestation length. [PDF]

open access: yesPLoS Biology, 2018
Pregnancy and parturition are intricately regulated to ensure successful reproductive outcomes. However, the factors that control gestational length in humans and other anthropoid primates remain poorly defined.

A Bibliometric Analysis of Publications in Uremic Toxins From 1991 to 2024

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Uremic toxins are a growing area of research in nephrology, with significant implications in the progression and treatment of chronic kidney disease (CKD) and the management of end‐stage kidney disease (ESKD). This bibliometric analysis aims to evaluate the global research trends, key contributors, and the impact of publications in ...

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.
