The Sun, the Moon, and the Orientation of Baltic Graves: A Mythological Approach to an Archaeological Problem
Solnce, luna i orientacija baltskih pogrebenij: mifologičeskij vzljad na arheologičeskuju problemu

Studia Mythologica Slavica, 2018
This paper focuses on the predominating east-west orientation of Iron Age graves (5th century BC to the 13th century AD) and the reasons that could have caused the custom.

Astronomical orientations in sanctuaries of Daunia

, 2013
Prehistoric sanctuaries of Daunia date back several thousand years. During the Neolithic and Bronze Age the farmers in that region dug hypogea and holes whose characteristics suggest a ritual use. In the present note we summarize the results of the astronomical analysis of the orientation of the row holes in three different sites, and we point out the ...

Atom Probe Tomography as an Emerging Tool for Understanding Defect‑Driven Mechanisms in HfO2‑Based Ferroelectrics

Advanced Functional Materials, EarlyView.
This Perspective highlights atom probe tomography as a powerful tool for understanding the atomic‐scale defect chemistry in HfO2‐based ferroelectrics. 3D mapping of dopants, point defects, and interface chemistry can provide new insight into defect‐driven mechanisms underpinning the ferroelectricity in the system and guide the design of more reliable ...

Archaeoastronomy in ancient Helvetia: the theater, the temple and the city of Aventicum (Avenches) [PDF]

Archaeoastronomy and Ancient Technologies, 2019
This article presents our discovery of the astronomical orientation of the city of Aventicum, the capital of ancient Roman Helvetia, where the sacred complex formed by the Temple of the Cigognier and the Theater were oriented along the axis that links ...

Bulk‐Like Spin Cycloid and Fast Switching in Freestanding BiFeO3

Advanced Functional Materials, EarlyView.
Freestanding BiFeO3 membranes overcome substrate‐induced constraints by simultaneously restoring the intrinsic bulk‐like spin cycloid and enabling ≈50% faster ferroelectric switching than substrate‐clamped epitaxial thin films. This combination of robust noncollinear antiferromagnetic order and efficient electric‐field switching establishes ...

Reservoir‐Driven Neuromorphic Computing Based on Composite Rare‐Earth/Transition Metal Oxide Memristor

Advanced Functional Materials, EarlyView.
A defect‐engineered Ag/Gd2O3:Nb2O5/Pt rare earth composite oxide memristor enables stable multilevel reservoir states through pulse driven conductance modulation. Experimentally measured device responses are incorporated into a device aware reservoir computing framework for CIFAR‐100 image classification, highlighting the potential of rare earth ...

The Orientation of Ancient Monuments in Sweden - A Critique of Archaeoastronorny and an Alternative Interpretation

Current Swedish Archaeology, 1997
The results of three archaeoastronomical studies of Scandinavian ancient monuments are discussed and dismissed as unconvincing. The necessity of a broader approach to the problem of orientation is emphasised.

Astronomy and mystic simbols in the Romanesque parish church of Santa Maria in Cortemilia (Cuneo, Italy) [PDF]

Archaeoastronomy and Ancient Technologies, 2016
Cortemilia, a town in Piedmont (Italy), is located in an area that in ancient times belonged to Ligurian tribes then conquered by the Romans. At the edge of the town is the Romanesque church of Santa Maria (Sancta Maria de Plebe) of the twelfth or ...

Accelerated Discovery of Topological Spin Phase Diagrams in CrSBr Magnets Via High‐Throughput Optimization

Advanced Functional Materials, EarlyView.
Here, we develop a high‐throughput algorithm that accelerates the elucidation of phase diagrams of topological spin textures using limited computational resources at high numerical accuracy. Applying this framework to the van der Waals magnet CrSBr, we unveiled a hierarchy of previously unknown topological textures (domain‐wall bimerons, bimeron chains,

Orientarea astronomică a unor cetăţi dacice

Arheologia Moldovei, 2016
Since mid II century BC economic and cultural flowering of Dacia was particularly illustrated by the emergence and development of fortified settlements and the construction of fortified cities, protected by stone walls (e.g. Orăştie-Mountains). Burebista
