Molecular methods for differentiating Phragmites australis subspecies and identification of hybrid stands in the Upper Midwestern United States

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise In North America, Phragmites australis (common reed) has drawn a great deal of research attention. Non‐native P. australis subsp. australis is a noxious weed that has locally displaced native P. australis subsp. americanus in some areas.

Diffusion‐Governed Growth Mechanisms of Epitaxial GaAs Islands on CMOS‐Compatible Si(001) Nanotip Arrays

open access: yesAdvanced Physics Research, EarlyView.
The mechanism and kinetics of selective GaAs growth on Si nanotip wafers via nanoheteroepitaxy were investigated as a function of pitch (center‐to‐center nanotip spacing). The pitch dependence reveals distinct surface‐diffusion‐controlled regimes, demonstrating that lateral Ga adatom transport on the SiO2 mask governs material redistribution and ...

An unusual titanosaur axis from the Upper Cretaceous of Brazil and its significance for sauropod anatomy and systematics

open access: yesThe Anatomical Record, EarlyView.
Abstract The Upper Cretaceous São José do Rio Preto Formation (Bauru Group, southeastern Brazil) has yielded a fragmentary but taxonomically diverse record of titanosaur sauropods, although elements from cervical series remain scarce. Here, we describe a nearly complete sauropod axis from the Vila Ventura Paleontological Area, representing an uncommon ...

Single‐Staged Combined Retrograde Subchondral Drilling and In Situ Autologous or Micronized Cartilage Repair With Bone Marrow Aspirate Concentrate for Focal Patellofemoral Chondral Lesions

open access: yesArthroscopy Techniques, EarlyView.
Abstract Patellofemoral cartilage lesions are uniquely challenging to treat due to high joint contact pressures, complex tracking mechanics, and limited intrinsic healing potential. Conventional methods such as debridement, microfracture, or staged autologous chondrocyte implantation may disrupt the calcified cartilage layer, violate the subchondral ...
