Plasma levels of luteinizing hormone and prolactin in relation to double brooding in Great Tit (Parus major)

open access: yesAvian Research, 2022
The reproductive behaviors of birds are mainly controlled by the hypothalamus-pituitary-gonad axis. Many studies have shown that reproductive hormones are tightly linked to the breeding sub-stages.

Genetic architecture of rainbow trout survival from egg to adult [PDF]

open access: yes, 2010
Survival from birth to a reproductive adult is a challenge that only robust individuals resistant to a variety of mortality factors will overcome. To assess whether survival traits share genetic architecture throughout the life cycle, we estimated ...

Comparative life stages and behavioral characteristics of two Spilomelinae moths with overlapping feeding periods on Azolla spp., in the northern Iran [PDF]

open access: yesJournal of Crop Protection, 2023
Diasemiopsis ramburialis and Nomophila noctuella are moths from Spilomelinae (Lepidoptera: Crambidae) with an overlapping feeding period on Azolla spp. in northern Iran. Due to some morphological similarities, immature stages often lead to confusion.

Explicit modeling of multi-period setup times in proportional lot-sizing and scheduling problem with variable capacity [PDF]

open access: yesArchives of Control Sciences, 2021
Small bucket models with many short fictitious micro-periods ensure high-quality schedules in multi-level systems, i.e., with multiple stages or dependent demand. In such models, setup times longer than a single period are, however, more likely.

A soluble phosphorylated tau signature links tau, amyloid and the evolution of stages of dominantly inherited Alzheimer’s disease

open access: yesNature Medicine, 2020
Development of tau-based therapies for Alzheimer’s disease requires an understanding of the timing of disease-related changes in tau. We quantified the phosphorylation state at multiple sites of the tau protein in cerebrospinal fluid markers across four ...
