Magnetron Sputtering Synthesis of La‐Doped BiFeO3 Thin Films and Enhanced Exchange Bias in CoFeB/Bi1‐xLaxFeO3 Heterostructures

open access: yesAdvanced Physics Research, EarlyView.
This study explores the epitaxial growth of high‐quality La‐doped BiFeO3 (BLFO) thin films at 550 °C using magnetron sputtering. The films exhibit good ferroelectric properties and low leakage current. A BLFO/CoFeB heterostructure is constructed, achieving an exchange bias field exceeding the coercive field at room temperature.

Much more than their fangs: Macroscopic anatomy of the brain of Bothrops moojeni Hoge 1966 (Squamata, Serpentes, Viperidae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

open access: yesThe Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Laura Chinellato: L’ara di Ratchis a Cividale

open access: yesArs & Humanitas, 2016
A good mosaic should have a clear-cut frame, a central panel proposing the main subject, and subsidiary ones amplifying the theme. Laura Chinellato’s L’ara di Ratchis a Cividale is indeed such a successful mosaic of words and ideas.

Mosaic Panel «Scythian Ukraine – Steppe Hellas» of Mykola Storozhenko. Architectonics of the Plastic Space

open access: yesResearch and methodological works of the National Academy of Visual Arts and Architecture, 2019
This article shows architectonical features of the plastic space in the mosaic panel of Mykola A. Storozhenko «Scythian Ukraine – Steppe Hellas» (1987–1992) and analyzes the composition structure of this work in the context of interrelationships of the multi-faceted imagery and symbolic formation.

Statistical properties of polarized CMB foreground maps

open access: yes, 2019
Foreground removal techniques for CMB analyses make specific assumptions about the properties of foregrounds in temperature and in polarization. By investigating the statistics of foreground components more understanding about the degree to which these ...

Cutting Through the Green: A Case for Grassland Archaeology Using UAV Multispectral Data

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Advances in low‐altitude remote sensing are needed to improve the effectiveness of archaeological prospection in the Netherlands. The geomorphological situation and land use history make applying various remote sensing and geophysical technologies particularly challenging.

Boundaries, Magic, and Popular Religion in two Mosaics from Ancient Thysdrus (El Jem in Tunisia)

open access: yesNew Classicists, 2020
Jerry Toner defines "popular culture" as "the culture of the non-elite" that was "the unofficial and subordinate culture of Roman society." (Toner 1) Magic, superstition, and religion were interchangeable in Roman antiquity.
