The inflated Chern-Simons number in spectator chromo-natural inflation

open access: yesJournal of High Energy Physics, 2023
The chromo-natural inflation (CNI) scenario predicts a potentially detectable chiral gravitational wave signal, generated by a Chern-Simons coupling between a rolling scalar axion field and an SU(2) gauge field with an isotropy-preserving classical ...

Ultrafilters on the natural numbers

open access: yesJournal of Symbolic Logic, 2003
AbstractWe study the problem of existence and generic existence of ultrafilters onω. We prove a conjecture of Jörg Brendle's showing that there is an ultrafilter that is countably closed but is not an ordinal ultrafilter under CH. We also show that Canjar's previous partial characterization of the generic existence of Q-points is the best that can be ...

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

open access: yesFEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

First Cytogenetic Study Through Conventional Staining of The Ant Genus Blepharidatta Wheeler, 1915 (Hymenoptera: Formicidae: Attini)

open access: yesSociobiology, 2022
Blepharidatta is a rare Neotropical ant genus in the Attini tribe of the subfamily Myrmicinae. It has only four valid species and among them Blepharidatta delabiei was recently described and there is little knowledge on its biology.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
