Embryological development and comparative analysis of Anguis colchica (Nordmann, 1840): Insights into ossification and morphological traits in anguimorph lizards

open access: yesJournal of Anatomy, Volume 247, Issue 6, Page 1157-1173, December 2025.
This study examines the embryonic development of Anguis colchica across three stages, highlighting key morphological and skeletal features. Ossification begins before stage 6, with cranial bones forming early, while frontal and parietal bones remain unfused at stage 7.

In vitro and in vivo Human Metabolism of (S)-[18F]Fluspidine – A Radioligand for Imaging σ1 Receptors With Positron Emission Tomography (PET)

open access: yesFrontiers in Pharmacology, 2019
(S)-[18F]fluspidine ((S)-[18F]1) has recently been explored for positron emission tomography (PET) imaging of sigma-1 receptors in humans. In the current report, we have used plasma samples of healthy volunteers to investigate the radiometabolites of (S)-

Raman spectra of epitaxial graphene on SiC and of epitaxial graphene transferred to SiO2

open access: yes, 2008
Raman spectra were measured for mono-, bi- and trilayer graphene grown on SiC by solid state graphitization, whereby the number of layers was pre-assigned by angle-resolved ultraviolet photoemission spectroscopy.

Emission Markets Linkage and Strategic Environmental Policy

open access: yesJournal of Public Economic Theory, Volume 27, Issue 6, December 2025.
ABSTRACT This study develops a strategic environmental policy model with linked emission permit markets. We examine whether a cooperative outcome can emerge when exporting countries act non‐cooperatively. We endogenize the participation decision through a specific permit revenue‐sharing scheme.

Wide bandgap semiconductor from a hidden 2D incommensurate graphene phase

open access: yes, 2016
Producing a usable semiconducting form of graphene has plagued the development of graphene electronics for nearly two decades. Now that new preparation methods have become available, graphene's intrinsic properties can be measured and the search for ...

Greenhouse gas emissions altered by the introduction of a year‐long fallow to continuous rice systems

open access: yesJournal of Environmental Quality, Volume 54, Issue 6, Page 1722-1736, November/December 2025.
Abstract Rice (Oryza sativa L.) production in California follows a norm of mono‐cropping with little to no rotations or fallows. Both winter droughts, which lead to water restrictions, and spring rains, which inhibit field machinery operations, have resulted in increased fallow frequencies, where no crop is grown during the summer growing season.
