Interactions and disorder in 2D graphite sheets [PDF]

open access: yesarXiv, 2005
The present work discusses theoretical models which address the effects of electron--electron interactions and disorder in graphene planes. The starting point for the study is a simple tight-binding model for the electronic structure followed by discussion of the interesting features induced by the unscreened Coulomb interaction.

Analysis pipeline to quantify uterine gland structural variations

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Technical advances in whole tissue imaging and clearing have allowed 3D reconstruction of exocrine uterine glands deep‐seated in the endometrium. However, there are limited gland structure analysis platforms to analyze these imaging data sets. Here, we present a pipeline for segmenting and analyzing uterine gland shape.

Comparative wood anatomy and origin of woodiness in subfamilies Secamonoideae and Asclepiadoideae (Apocynaceae)

open access: yesTAXON, Volume 71, Issue 6, Page 1230-1250, December 2022., 2022
Abstract The Apocynaceae subfamilies Secamonoideae and Asclepiadoideae have undergone several transitions during their evolution with regard to growth form and degree of woodiness. In this study, we present a wood anatomical overview of both subfamilies that complements previous work on the remaining Apocynaceae.

Phylogenomics and generic limits of Dypsidinae (Arecaceae), the largest palm radiation in Madagascar

open access: yesTAXON, Volume 71, Issue 6, Page 1170-1195, December 2022., 2022
Abstract With 178 species, palm subtribe Dypsidinae is one of the largest plant radiations on Madagascar. A well‐resolved species‐level phylogeny is required not only to unpick the drivers of this spectacular radiation, but also to define natural and useful generic limits in this taxonomically difficult group.
