Densely vascularized thick 3D tissue shows enhanced protein secretion constructed with intermittent positive pressure

open access: yesCommunications Biology
Constructing a dense vascular endothelial network within engineered tissue is crucial for successful engraftment. The present study investigated the effects of air-compressing intermittent positive pressure (IPP) on co-cultured mesenchymal stem cells and

Gegenbauer’s Twin

open access: yesJournal of High Energy Physics, 2022
Abstract In Twin Higgs models the dominant source of fine-tuning is the cancellation of order v2/f2 required to obtain a Standard Model-like Higgs, where v and f are the electroweak and new physics scales, respectively. Recently proposed Gegenbauer Goldstone models naturally realise v2/f2 « 1 and hence remove this source of fine ...

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Where Do Cultural Tastes Come From? Genes, Environments, or Experiences

open access: yesSociological Science, 2022
Theories in sociology argue that family background and individual experiences shape cultural tastes and participation. Yet, we do not know the relative importance of each explanation or the extent to which family background operates via shared genes or ...

occumb: An R package for site occupancy modeling of eDNA metabarcoding data

open access: yesPopulation Ecology, EarlyView.
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using

The detailed chemical composition of the terrestrial planet host Kepler-10

open access: yes, 2015
Chemical abundance studies of the Sun and solar twins have demonstrated that the solar composition of refractory elements is depleted when compared to volatile elements, which could be due to the formation of terrestrial planets.

Twin-to-Twin Transfusion Syndrome

open access: yesPostgraduate Medicine, 1970
Plethora in one of a pair of monozygotic twins and pallor in the other are now understood as evidence of intrauterine transfer of blood by way of vascular anastomoses in the placenta. The artery-to-vein type of communication acts as an arteriovenous shunt. The syndrome is an important cause of fetal and neonatal morbidity and mortality.

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders

open access: yesPopulation Ecology, EarlyView.
We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...
